[0024] Below, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] like Figures 1 to 7 As shown, a new type of rear-end threaded modified car shock absorber includes a shock absorber oil storage cylinder 5, a piston rod 2 and a rod head accessory 1. The piston rod 2 is inserted into the shock absorber oil storage cylinder 5, and the rod head accessory 1 is fixed to the end of the piston rod 2. An external thread 52 is provided on the outer peripheral wall of the middle part of the shock absorber oil storage cylinder 5, and a threaded tray 4 is provided on the external thread 52. The threaded tray 4 is threadedly connected to the shock absorber oil storage cylinder 5; the surface of the shock absorber oil storage cylinder 5 is brushed and galvanized, which is anti-corrosion and wear-resistant, thereby extending the service life.

[0027] An external thread 52 is provided on the lower outer peripheral wall of the shock absorber oil storage cylinder 5, and a lower connecting assembly 6 is provided on the external thread 52. The lower connecting assembly 6 includes a lower connecting threaded barrel and a lifting ring 8. An iron rubber sleeve 7 is provided inside the lifting ring 8. The iron rubber sleeve 7 is provided inside the lifting ring 8 to increase the connection strength. The lower connecting threaded barrel is threadedly connected to the shock absorber oil storage cylinder 5, and the lifting ring 8 is welded and fixed to the lower connecting threaded barrel.

[0028] An adjustment bushing 9 is provided at the lower end of the shock absorber oil reservoir 5. The adjustment bushing 9 is fixed to the outer peripheral wall of the shock absorber oil reservoir 5. The outer peripheral wall of the adjustment bushing 9 is provided with an external thread 52. The lower connecting threaded barrel is sleeved on the adjustment bushing 9 and threadedly connected thereto. The provision of the adjustment bushing 9 is to reduce wear on the shock absorber oil reservoir 5.

[0029] The shock absorber oil storage cylinder 5 is also provided with a limiting ring 51 and a locking ring 41. The limiting ring 51 is fixed to the upper part of the threaded tray 4 and is welded to the outer peripheral wall of the shock absorber oil storage cylinder 5. The limiting ring 51 prevents the threaded tray 4 from sliding upward. The locking ring 41 is arranged at the lower part of the threaded tray 4 and is threadedly connected to the shock absorber oil storage cylinder 5. The locking ring 41 plays a locking role to prevent the threaded tray 4 from accidentally loosening, and also plays a downward limiting role.

[0030] In order to facilitate installation and disassembly, a plurality of rotating blocks 61 are provided on the lower connecting threaded barrel. The rotating blocks 61 are connected to the lower connecting threaded barrel as a whole. The setting of the rotating blocks 61 is convenient for rotating operations using tools. A plurality of heat dissipation grooves 62 are provided on the surface of the lower connecting threaded barrel. The setting of the heat dissipation grooves 62 is conducive to heat dissipation and prolonging service life.

[0031] The outer wall of the threaded tray 4 is provided with a plurality of notches 42, which facilitate the application of force by tools. The outer wall of the locking ring 41 is provided with a plurality of protrusions 411, which are also for the convenience of installation and removal using tools.

[0032] In order to protect the shock absorber from dust and impurities, a dust cover 3 is provided on the outside of the shock absorber oil storage cylinder 5. The dust cover 3 is sleeved on the shock absorber oil storage cylinder 5. One end of the dust cover 3 is fixedly connected to the outer wall of the rod head attachment 1, and the other end is fixedly connected to the outer wall of the shock absorber oil storage cylinder 5. The dust cover 3 is made of flexible and retractable material and can adapt to the expansion and contraction changes of the shock absorber during operation.

[0033] The principle of use of the utility model is: when in use, the external threads 52 on the middle and lower outer peripheral walls of the shock absorber oil storage cylinder 5 are respectively threadedly connected to the threaded tray 4 and the lower connecting assembly 6, the lifting ring 8 is welded to the lower connecting threaded cylinder, and the iron rubber sleeve 7 is ensured to be installed in place;

[0034] As needed, the height of the shock absorber can be adjusted by rotating the lower connecting threaded barrel and the threaded tray 4 respectively. The threaded tray 4 can be fixed using a locking ring 41.

[0035] When a vehicle travels on an uneven road, the wheels will bounce up and down, driving the piston rod 2 to move up and down in the shock absorber oil storage cylinder 5. The movement of the piston rod 2 pushes the piston to slide in the oil storage cylinder. The throttle hole or valve on the piston adjusts the flow of the shock absorber oil according to the movement speed. The shock absorber oil generates a damping force at the throttle hole or valve, converting the vibration energy into heat energy, and dissipating it into the atmosphere through the oil storage cylinder wall and the heat dissipation groove 62.

[0036] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
