With the repeated outbreak of the new crown epidemic, it has become an unchangeable fact that the global economy will continue to decline in the short term. Business orders continued to decrease, factories were laid off in large numbers, and people's spending power continued to decline, making the real estate industry, which was already on the verge of collapse, even worse, and on the verge of collapse. The entire home building materials industry was severely impacted.

Not only that, Huawei, the big brother in the communications industry, which is closely related to people's daily life, has strong financial and technical strength, and has also begun to prepare for the winter under the orders of Mr. Ren.

On the one hand, it has changed its thinking and business policy, and shifted from pursuing scale to pursuing profit and cash flow, so as to ensure that it will survive the crisis in the next three years. On the other hand, surviving is the main program, and edge businesses are shrunk and closed across the board, passing the chill to everyone.

"Three years", as a profit-making period of an enterprise, seems to have passed in a blink of an eye. If it is regarded as a loss-making period, it will be an insurmountable gap for most of the manufacturing enterprises with low profits. How to survive in the next three years, even with quality, has become a question that every enterprise leader must think deeply about.

Resilience and vitality-the British business community is optimistic about China's economic prospects(2)

The British Directors Association was established in 1903 and is one of the most prestigious business associations in the UK. John McLean, the new chairman of the London Branch of the British Board of Directors, said that the Chinese market is very important to British companies and he believes that the two sides will strengthen cooperation in many areas.

McLean said that with Britain leaving the European Union, British companies need to "look east." The Chinese economy continues to grow and there are more and more middle-class consumer groups, which is very attractive to British companies. With the gradual recovery of the tourism industry from the new crown epidemic and the gradual increase in personnel exchanges, the UK and China will further strengthen economic cooperation.

Talking about the potential areas of cooperation between Britain and China, McLean said that the two countries have broad prospects for cooperation in the fields of global finance and innovation, green industry and environment, and healthcare.

William Russell, the mayor of the City of London, said in an interview that the City of London looks forward to maintaining a strong relationship with relevant Chinese institutions and jointly promoting green finance cooperation.

Speaking of China's financial industry becoming more open, Russell said that this is good news. "We hope that as the (opening) door opens wider and wider, we continue to cooperate with China. We hope that more Chinese financial companies will come to London to set up offices."

Gas springs play a crucial role in various mechanical applications, whether it's in office chairs or heavy machinery. These innovative devices utilize compressed nitrogen gas to generate force and aid in the movement of different machinery components. In this comprehensive article, we will delve into the workings of gas springs, including their construction, components, and functions.

The construction of gas springs is relatively straightforward, consisting of a cylinder filled with nitrogen gas, a piston rod, and a piston. Depending on the application, the cylinder can be made from stainless steel, plastic, or aluminum, and it is securely sealed. The piston rod is inserted into the cylinder, with the piston attached to its end. The piston is equipped with a valve that regulates the flow of nitrogen gas between the cylinder and the piston.

Components of Gas Springs

Gas springs primarily rely on three major components: the cylinder, piston rod, and piston. Each of these components plays a vital role in the gas spring's overall function.

Cylinder: The cylinder serves as the key element of the gas spring, housing the nitrogen gas and maintaining it under pressure. Different types of cylinders, such as stainless steel ones for corrosive environments or aluminum counterparts for weight-sensitive applications, are utilized based on the specific requirements.

Piston Rod: Connecting the piston to the rest of the machinery, the piston rod is typically made from stainless steel or aluminum. To enhance its lifespan and minimize friction, the piston rod can undergo coating or polishing.

Piston: Arguably the most critical component, the piston controls the flow of nitrogen gas between the cylinder and piston rod. Its design ensures that the cylinder is sealed, preventing any gas leakage. Additionally, the piston can be equipped with a valve to adjust the gas pressure, enabling the gas spring to accommodate different loads.

Functions of Gas Springs

Gas springs serve several key functions in machinery applications:

4. Safety: In applications like adjustable chairs, gas springs prevent sudden and unexpected movements that could potentially cause harm to machinery operators.

How Gas Springs Work

The operation of gas springs is relatively simple yet effective. When a load is applied to the piston rod, it displaces the piston inside the cylinder, compressing the nitrogen gas. As the gas is compressed, it exerts force on the piston, generating energy. This energy is then transmitted to the piston rod, facilitating movement in the machinery.

When the load is removed, the compressed gas expands, allowing the piston to return to its original position. This cyclic process continues as long as the load is present, resulting in controlled and seamless machinery movement.

Adjusting Gas Springs

Gas springs can be adjusted to accommodate varying loads. This adjustment is made by manipulating the valve within the piston. By altering the valve, the gas pressure can be increased or decreased, ultimately affecting the force generated by the gas spring. The adjustment can be done manually or automatically, depending on the specific application.

Before making any adjustments, it is important to identify and diagnose the problematic issues with gas springs. This is critical to finding the best solution and avoiding unnecessary adjustments. Some common issues with gas springs include insufficient force, excessive force, and sagging. Insufficient force occurs when the gas spring is overloaded and lacks the strength to lift and support the weight. Excessive force can be a safety hazard as it can damage materials or cause injury. Sagging can occur due to temperature changes or wear and tear.

Adjusting gas springs depends on their force output, which can be determined by the manufacturer's specifications or the label attached to the cylinder. To decrease the force of a gas spring, start by loosening the adjustment valve. You can do this by applying a 1/8 turn with an adjustable wrench. Loosening the valve slows down the flow of gas, reducing the force. On the other hand, to increase the force, tighten the adjustment valve by applying a clockwise 1/8 turn. It is essential to make small adjustments and test before repeating the process.

Sagging is a common issue with gas springs over time. To adjust for sagging, some gas spring designs have an adjustable pin on the cylinder. You can tighten this pin using an Allen wrench. By doing so, you increase the tension of the spring, reducing sagging. Additionally, you can adjust the length of the gas spring by extending it to its fullest extension, relieving the pressure, and then measuring and resetting it to the original length using adjustable pliers. The stroke length can also be adjusted by turning the control valve counterclockwise to reduce the stroke or clockwise to increase it.

In conclusion, it is evident that gas springs are reliable and beneficial components in various applications. However, adjustments may be required to meet specific needs or address issues such as sagging. It is crucial to follow the manufacturer's instructions and seek professional help when dealing with large or high-pressure gas springs.

As more and more people embrace the DIY (Do-It-Yourself) trend, many are taking on the challenge of building and renovating their own cabinets. However, before you start purchasing hinges for your cabinet, it's important to understand the different types available and how they vary based on the position of the door and side panels.

Hinges can be categorized into three types: full cover, half cover, and large bend. Let's take a closer look at each type and how to determine which one is suitable for your cabinet.

The full cover hinge, also known as the straight arm hinge, is designed for a door panel that fully covers the vertical side of the cabinet. On the other hand, the half cover hinge is meant for a door panel that covers only half of the side of the cabinet. Lastly, the large bend hinge is used when the door panel does not cover the side of the cabinet at all.

The choice between full cover, half cover, and large bend hinges depends on the side panel of your cabinet. Typically, the side panel thickness ranges from 16-18mm. The cover side panel is around 6-9mm thick, while the inlay type means that the door panel and side panel are on the same plane.

In practice, if your cabinet is constructed by a professional decorator, it will most likely feature half cover hinges. However, if you opt for a custom-made cabinet from a professional factory, then it will likely come with full cover hinges.

In summary, here are some key points about hinges:
