Description

Technical Field

[0001] The utility model relates to the technical field of gas spring support rods, in particular to a gas spring support rod which is easy to lubricate. Background Art

[0002] A gas spring support rod is a device used to support and adjust loads. It is commonly used in various applications such as automobiles, industrial machinery, furniture, etc. It is usually composed of a gas spring, a piston, a cylinder, etc. A gas spring is a device that uses the compression properties of gas to store energy and provide supporting force. When the gas spring is compressed, the gas is compressed in the cylinder to generate supporting force. When the external pressure decreases or disappears, the gas spring will return to its original state and release the stored energy.

[0003] After searching, a gas spring support rod with announcement number CN220622572U "comprises a cylinder body, a vent hole is provided on one side of the top of the cylinder body, a rubber outer membrane is fitted and connected to the outer wall of the top peripheral side of the cylinder body, an inner sealing ring is fixedly connected to the inner wall of the top of the cylinder body, and an oil inlet reserved hole is provided on the surface of the rubber outer membrane. The utility model can inject lubricating oil into the inside of the oil storage ring through the oil injection assembly through the relationship between the oil storage ring, the oil injection assembly, the rubber inner membrane, the oil outlet reserved hole, the inner sealing ring, the outer sealing ring, the oil seal assembly, the first wave sealing ring, the second wave sealing ring, the rubber outer membrane and the oil inlet reserved hole, so as to ensure that a thin layer of lubricating oil is attached to the surface of the piston rod, and the user does not need to manually apply lubricating oil to the surface of the piston rod. When the gas spring support rod is working, the piston rod can be evenly attached to a layer of lubricating oil when the piston rod performs piston motion inside the cylinder body";

[0004] Based on the above patent, through the relationship between the oil storage ring, the oil injection assembly, the rubber inner membrane, the oil outlet reserved hole, the inner sealing ring, the outer sealing ring, the oil seal assembly, the first wave sealing ring, the second wave sealing ring, the rubber outer membrane and the oil inlet reserved hole, the lubricating oil can be injected into the interior of the oil storage ring through the oil injection assembly, so as to ensure that a thin layer of lubricating oil is attached to the surface of the piston rod, and there is no need for the user to manually apply lubricating oil to the surface of the piston rod. When the gas spring support rod is working, a layer of lubricating oil can be evenly attached to the surface when the piston rod performs piston movement inside the cylinder body. However, when the device is in use, the lubricating oil is stored through the oil storage ring so that the lubricating oil can naturally flow into the cylinder body. There may be a situation where the lubricating oil flow speed is not fast enough and lubrication cannot be performed in time, resulting in increased wear of the parts of the gas spring support rod, thereby affecting the service life. The gas spring support rod is usually fixed as a whole, which makes maintenance and replacement more difficult, affecting the use efficiency and availability of the gas spring support rod. Therefore, the present application proposes a gas spring support rod that is easy to lubricate. Utility Model Content
