AI Technical Summary
The rebound adjustment structure of existing nitrogen shock absorbers requires a large space and cannot be used for products with relatively tight stroke space.
A nitrogen shock absorber rebound adjustment structure is designed. By setting threaded holes and conical grooves on the connecting seat, the contact between the conical surface of the rebound adjustment core and the spherical thimble is used to combine the movement of the piston rod and the spherical thimble to release the stroke, and the sealing performance is improved through the sealing ring.
It effectively reduces the stroke occupied by the rebound adjustment core, and is suitable for nitrogen shock absorbers with smaller internal strokes, improving space utilization.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of shock absorbers, in particular to a nitrogen shock absorber rebound adjustment structure. Background Art
[0002] The commonly used rebound adjustment structure of nitrogen shock absorbers usually requires a space of 12 - 15 mm. With limited space, it is not applicable to some products with relatively tight stroke space. Therefore, it is necessary to reduce the stroke occupied by the adjustment core to meet the production requirements. Summary of the Utility Model
[0003] The purpose of the utility model is to provide a nitrogen shock absorber rebound adjustment structure aiming at the defects and deficiencies of the prior art.
[0004] To achieve the above purpose, the technical solution adopted by the utility model is: a nitrogen shock absorber rebound adjustment structure, including a connection seat. The innovation lies in that: a threaded hole is radially opened in the connection seat, and a rebound adjustment core is threadedly connected in the threaded hole. An annular tapered groove is opened in the middle and lower part of the rebound adjustment core, so that a conical surface is formed on the surface of the rebound adjustment core; a piston rod is axially arranged on the connection seat, and a spherical top pin is arranged inside the piston rod. The front end of the spherical top pin penetrates into the threaded hole and contacts the conical surface.
[0005] Further, an installation hole is horizontally opened inside the rebound adjustment core. The installation hole is located above the conical surface. A spring is arranged inside the installation hole, and steel balls are arranged at the left and right ends of the spring.
[0006] Further, a sealing ring is arranged between the threaded hole and the rebound adjustment core.
[0007] After adopting the above structure, the beneficial effects of the utility model are as follows:
[0008] By rotating the rebound adjustment core of the utility model to make its conical surface contact with the spherical top pin, the spherical top pin moves back and forth, and by the way of the up and down movement of the conical surface, the stroke is released, the stroke occupied by the adjustment core is reduced, and it is applicable to some nitrogen shock absorbers with a smaller internal stroke.

[0010] Explanation of the Reference Numerals in the Drawings:
[0011] 1 connection seat, 2 threaded hole, 3 rebound adjustment core, 31 tapered groove, 32 conical surface, 33 spring, 34 steel ball, 4 piston rod, 5 spherical top pin, 6 sealing ring. Detailed Description of the Invention
[0012] The present utility model will be further described below in conjunction with the accompanying drawings.
[0013] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be 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 utility model and are not used to limit the present utility model.
[0014] Refer to Figure 1 , a nitrogen shock absorber rebound adjustment structure, including a connection seat 1. A threaded hole 2 is radially opened in the connection seat 1. A rebound adjustment core 3 is threadedly connected in the threaded hole 2. An annular tapered groove 31 is opened in the middle and lower part of the rebound adjustment core 3, so that a tapered surface 32 is formed on the surface of the rebound adjustment core; a piston rod 4 is axially arranged on the connection seat 1, and a spherical thimble 5 is arranged inside the piston rod 4. The front end of the spherical thimble 5 penetrates into the threaded hole 2 and contacts the tapered surface 32. Specifically, by rotating the rebound adjustment core 3, its tapered surface 32 is made to contact the spherical thimble 5, so that the spherical thimble 5 moves back and forth. By means of the up and down movement of the tapered surface 32, the stroke is released, and the stroke occupied by the rebound adjustment core 3 is reduced, which is applicable to some nitrogen shock absorbers with a smaller internal stroke; by means of the up and down movement of the tapered surface, a stroke of at least 3 mm can be released, and the stroke occupied by the rebound adjustment core 3 is reduced to 9 mm, which is applicable to some nitrogen shock absorbers with a smaller internal stroke.
[0015] In this embodiment, an installation hole is horizontally opened inside the rebound adjustment core 3. The installation hole is located above the tapered surface. A spring 33 is arranged inside the installation hole, and steel balls 34 are arranged at the left and right ends of the spring 33. The use of the spring 33 and the steel balls 34 makes the rebound adjustment core 3 have a certain sense of gear when rotating.
[0016] In this embodiment, a sealing ring 6 is arranged between the threaded hole 2 and the rebound adjustment core 3. The sealing ring 6 is used to improve the sealing performance of the two.
[0017] The above is only used to illustrate the technical solutions of the present utility model and not to limit them. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solutions of the present utility model should be covered within the scope of the claims of the present utility model as long as they do not depart from the spirit and scope of the technical solutions of the present utility model.
