Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of shock absorbers, in particular to a nitrogen shock absorber connecting seat rebound adjustment structure. Background Art
[0002] Some rebound adjustment structures of nitrogen shock absorbers are prone to getting stuck, making the rebound difficult to adjust and the adjustment range small. Utility Model Content
[0003] The purpose of the utility model is to provide a nitrogen shock absorber connecting seat rebound adjustment structure in response to the defects and shortcomings of the existing technology.
[0004] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a nitrogen shock absorber connecting seat rebound adjustment structure, including a piston rod and a connecting seat, the innovation of which is that a spherical ejector pin and a rotating shaft are arranged horizontally inside the piston rod, a threaded hole is arranged longitudinally inside the connecting seat, a rebound adjustment core is threadedly connected to the threaded hole, a circle of curved surface is provided on the outer surface of the rebound adjustment core, and the spherical ejector pin and the rotating shaft are always pressed against the curved surface under the action of air pressure, and the top of the rebound adjustment core is fixedly connected to the rebound adjustment button by a flat head screw.
[0005] Furthermore, a steel ball and a spring are arranged inside the rebound adjustment core.
[0006] Furthermore, a positioning shaft is provided at the bottom center of the rebound adjustment core.
[0007] Furthermore, an elastic retaining ring is provided between the rebound adjustment core and the rebound adjustment button.
[0008] Furthermore, a sealing ring is provided on the outside of the rebound adjustment button.
[0009] After adopting the above structure, the beneficial effects of the utility model are:
[0010] The utility model adopts a rebound adjustment core with a curved surface. The smooth curved surface makes the adjustment of the spherical ejector smoother, so that the rebound adjustment is smooth without sticking, and increases the distance of the spherical ejector moving forward and backward to 3mm, thereby expanding the range of the rebound adjustment. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Description of reference numerals:
[0013] 1 piston rod, 2 connecting seat, 3 spherical ejector pin, 4 rotating shaft, 5 threaded hole, 6 rebound adjustment core, 7 curved surface, 8 flat head screw, 9 rebound adjustment knob, 10 steel ball, 11 spring, 12 positioning shaft, 13 elastic retaining ring, 14 sealing ring. DETAILED DESCRIPTION
[0014] The present invention will be further described below with reference to the accompanying drawings.
[0015] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0016] See Figure 1 A nitrogen shock absorber connecting seat rebound adjustment structure includes a piston rod 1 and a connecting seat 2. A spherical ejector pin 3 and a rotating shaft 4 are arranged horizontally inside the piston rod 1. A threaded hole 5 is arranged longitudinally inside the connecting seat 2. The threaded hole 5 is threadedly connected to a rebound adjustment core 6. The outer surface of the rebound adjustment core 6 is provided with a circle of curved surface 7. The spherical ejector pin 3 and the rotating shaft 4 are acted upon by air pressure so that the spherical ejector pin 3 always rests on the curved surface 7. The top of the rebound adjustment core 6 is fixedly connected to the rebound adjustment button 9 by a flat head screw 8. Specifically, the spherical ejector pin 3 always rests on the curved surface 7 under the action of air pressure. The smooth curved surface 7 makes the adjustment of the spherical ejector pin 3 smoother, and the rebound adjustment core 6 is smooth and free of jamming. The distance that the spherical ejector pin moves back and forth is increased to 3 mm, thereby expanding the range of rebound adjustment.
[0017] In this embodiment, a steel ball 10 and a spring 11 are provided inside the rebound adjustment core 6 , which can enhance the gear position feeling when the rebound adjustment core 6 rotates.
[0018] In this embodiment, a positioning shaft 12 is provided at the bottom center of the rebound adjustment core 6. This ensures that the rebound adjustment core 6 rotates around the positioning shaft 12, thereby improving the stability of the rotation.
[0019] In this embodiment, an elastic circlip 13 is provided between the rebound adjustment core 6 and the rebound adjustment button 9. The elastic circlip 13 limits the rebound adjustment core 6 to prevent the rebound adjustment core 6 from being separated.
[0020] In this embodiment, a sealing ring 14 is provided on the outside of the rebound adjustment button 9 to improve the sealing performance.
[0021] The above description is only used to illustrate the technical solution of the present invention and is not intended to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
