Problems solved by technology
[0003] The technical problem to be solved by the present invention is: in order to solve the situation in the prior art where the load is variable, due to the frequent movement of the piston rod, the piston often collides with the upper sealing assembly, which will cause friction between the piston and the piston rod for a long time. To solve the problem of connection failure, a gas spring suitable for variable loads is now provided

Embodiment 1
[0015] Such as figure 1 As shown, a gas spring suitable for variable loads includes a pressure tube 1 with a piston chamber 101, a sealing assembly, a piston rod 3 and a piston 4, and the sealing assembly is installed at the head end of the piston chamber 101, so The piston 4 is slidingly arranged in the piston cavity 101, the piston rod 3 is inserted in the piston cavity 101, one end of the piston rod 3 is fixedly connected with the piston 4, and the other end of the piston rod 3 One end protrudes from the piston cavity 101, and the piston rod 3 has a shoulder 5 above the piston 4. The distance between the lower surface of the shoulder 5 and the upper surface of the piston 4 is 2mm. The shoulder 5 A reinforcing plate 6 is arranged between the lower surface of the piston rod 3 and the piston rod 3 .
[0016] The sealing assembly includes an annular seal 2 made of rubber, the seal 2 is arranged at the head end of the piston chamber 101 on the pressure tube 1 , the inner ring w...

The invention relates to the technical field of gas springs, in particular to a gas spring suitable for changeable loads. The gas spring comprises a pressure pipe with a piston cavity, a sealing assembly, a piston rod and a piston. The sealing assembly is mounted at the head end of the piston cavity, the piston is arranged in the piston cavity in a sliding manner, the piston rod is inserted in the piston cavity, one end of the piston rod is fixedly connected with the piston, and the other end of the piston rod stretches out of the piston cavity; and a shaft shoulder is arranged at the position, located above the piston, of the piston rod, and a reinforcing plate is arranged between the lower surface of the shaft shoulder and the piston rod. According to the gas spring suitable for the changeable loads, the shaft shoulder is additionally arranged on the piston rod, collision between the piston and the sealing assembly is prevented, the service life of the piston is effectively prolonged, an annular sewage sump can remove dirt on the piston rod, motion flexibility of the piston rod is ensured, and meanwhile sealing between the sealing assembly and the piston rod is improved.
Description
technical field [0001] The invention relates to the technical field of gas springs, in particular to a gas spring suitable for variable loads. Background technique [0002] Since the gas spring has a relatively close to ideal quadratic curve elastic change characteristic, it has been widely used in many industries such as the automobile industry, printing machinery, medical equipment, office equipment, furniture manufacturing, industrial machinery, aerospace, and locomotive manufacturing. When some gas springs are used in occasions with variable loads, due to the frequent movement of the piston rod, the piston often impacts and collides with the upper sealing assembly, which will cause the connection between the piston and the piston rod to fail for a long time, and the piston will crack in severe cases And scrapped. Contents of the invention [0003] The technical problem to be solved by the present invention is: in order to solve the situation in the prior art where the...
