[0002] Shock absorbers are widely used in the automotive industry. They are mainly used to suppress the shock caused by the rebound of the spring after absorbing the shock and the impact from the road surface, so as to improve the smoothness and comfort of the car. Its background technology can be traced back to the early 20th century. The earliest automobile shock absorber was a mechanical shock absorber that controlled the shock absorption effect of the vehicle through metal springs and hydraulic cylinders.
[0003] After consulting the relevant patent document CN218761088U, it is found that there are still some problems with the existing spring shock absorber. The optimization scheme currently on the market is mainly: two springs are arranged on the inner rod, spring one is on the outside, spring two is on the inside, and both ends are fixed, when spring one is compressed, spring two is stretched, and it is in an extended state, when spring one rebounds, spring two is compressed, so that the rebound force is offset by spring two, and then the forces between the two springs are offset to achieve a better shock absorption effect, but it is easy to get stuck after a long period of use, but it is difficult for users to disassemble the sealed shock absorber. In view of the above problems, a spring shock absorber that can easily install and replace parts and is easy to fix is proposed. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the present invention are:
[0013] 1. This kind of spring shock absorber that is easy to install is provided with an installation mechanism. When the spring shock absorber needs to be installed, first, the sliding rod and the chassis are placed into the interior of the sleeve through the hole of the sleeve, and then the telescopic spring is put on the surface of the sliding rod. Then, the limit cap is rotated and fixed to the threaded end of the sliding rod, and then the anti-slip sheet is pressed until the two sets of anti-slip sheets touch each other, and then the middle-layer protrusion is clamped into the inner wall of the sleeve. At the same time, the positioning gasket will press against the surface of the sliding rod, and the inner wall of the anti-slip sheet will be clamped on the outer surface of the sleeve, and then the anti-slip sheet can be loosened. At this time, under the action of the rebound force of the reset spring, the middle-layer protrusion is pressed outward through the support block, so that the middle-layer protrusion can be firmly buckled on the inner wall of the sleeve, and the installation is simple and convenient.
[0014] 2. This easy-to-install spring shock absorber is provided with a waterproof gasket. After the installation of the sliding rod is completed, the inner wall of the sleeve is buckled in the position between the inner gasket and the outer gasket, and then the bottom cover is inserted into the inner wall of the inner gasket to complete the installation. Before inserting the bottom cover, oily liquid needs to be poured into the inside of the sleeve. Since a waterproof hole is provided on the inner wall of the inner gasket, the bottom cover and the waterproof hole fit tightly, and the oily liquid will not leak out. When the chassis slides inside the sleeve, the oily liquid will flow back and forth through the oil filter holes on the surface of the chassis, so that the chassis slides more smoothly under the action of the telescopic spring, thereby improving the shock absorption effect.
