[0011] 1 threaded connecting rod, 2 upper connecting seat, 21 base, 22 protrusion, 3 oil storage cylinder, 4 piston rod, 5 buffer block, 6 lower connecting seat, 7 oil pipe assembly, 8 nitrogen cylinder, 9 compression adjustment assembly. DETAILED DESCRIPTION

[0012] The utility model is further described below in conjunction with the accompanying drawings.

[0013] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described here are only used to explain the utility model and are not used to limit the utility model.

[0014] See also Figure 1 A tubular nitrogen shock absorber includes a threaded connecting rod 1, an upper connecting seat 2, an oil storage cylinder 3, a piston rod 4, a buffer block 5, a lower connecting seat 6, an oil pipe assembly 7 and a nitrogen cylinder 8; an upper connecting seat 2 is arranged on the top of the oil storage cylinder 3, and the upper connecting seat 2 includes a truncated cone structure base 21 and a hexagonal prism structure protrusion 22, and a threaded connecting rod 1 is arranged on the top of the upper connecting seat 2; a buffer block 5 is arranged on the bottom of the piston rod 4, and a lower connecting seat 6 is arranged on the bottom of the buffer block 5; the upper connecting seat 2 is connected to the nitrogen cylinder 8 through the oil pipe assembly 7. Specifically, the truncated cone structure base 21 and the threaded connecting rod 1 of the upper connecting seat 2 occupy less space, and the threaded connecting rod 1 can be directly installed, which greatly improves the convenience of disassembly and assembly of the shock absorber; the protrusion 22 of the hexagonal prism structure on the upper connecting seat 2, the six faces of the hexagonal prism are equivalent to reinforcing ribs, so the overall strength can be improved.

[0015] In this embodiment, a compression regulating assembly 9 is provided at the output end of the nitrogen cylinder 8. The compression regulating assembly 9 is used to regulate the output of the nitrogen cylinder.

[0016] The above description is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
