Description

Technical Field

[0001] The utility model relates to the technical field of gas spring protection, in particular to a protection structure for a gas spring. Background Art

[0002] Gas springs have a wide range of uses. Their working principle is to fill a closed pressure cylinder with inert gas or an oil-gas mixture, making the pressure in the cavity many times higher than the atmospheric pressure. The cross-sectional area of ​​the piston rod is smaller than the cross-sectional area of ​​the piston, thereby generating a pressure difference to achieve the movement of the piston rod.

[0003] During the use of the gas spring, when the piston rod is pulled out of the cylinder, if the piston rod is hit by an external force after the displacement, the connection between the piston rod and the cylinder is prone to deformation or breakage, thereby affecting the subsequent use of the gas spring.

[0004] A gas spring with a protective structure disclosed in announcement number CN217481832U includes a cylinder and a piston rod slidably connected to the end of the cylinder. The end of the cylinder corresponding to the piston rod is provided with a protective assembly. The protective assembly specifically includes a rubber ring. A plurality of reinforcing rods are symmetrically fixedly installed inside the rubber ring. The reinforcing rods pass through the inside of the rubber ring and extend outside the rubber ring. Positions corresponding to the reinforcing rods on the cylinder are provided with sockets matching the reinforcing rods, and the reinforcing rods are inserted into the sockets. In this gas spring with a protective structure, when the piston rod is pulled out of the cylinder, the protective assembly is located at the connection between the cylinder and the piston rod, thereby strengthening the connection between the cylinder and the piston rod and preventing the piston rod from breaking at the connection with the cylinder when it is hit by an external force.

[0005] Although the above patent has achieved a gas spring with a protective structure, when the piston rod is pulled out of the cylinder, the protective component is located at the connection between the cylinder and the piston rod, thereby strengthening the connection between the cylinder and the piston rod and preventing the piston rod from breaking at the connection with the cylinder when impacted by external force; however, the device lacks a buffer component. When the gas spring contracts, if the contraction speed is too fast, the impact force brought by the extension rod will cause damage to the gas spring.

[0006] Therefore, it is necessary to invent a gas spring protective structure to solve the above problems. Utility Model Content

[0007] The technical problems to be solved by the present invention are as follows: to provide a protective structure for a gas spring which is highly practical, can be easily operated, and has a relatively simple structure, thereby solving the problem of the lack of a buffer component in the above-mentioned background technology.
