[0002] A spring is a mechanical part that uses elasticity to work. The force and deformation of a spring conform to Hooke's law, that is, the force and deformation must be proportional. Spring shock absorbers are mainly used to suppress the shock caused by the spring rebounding after absorbing shock and the impact from the road surface. At present, in order to make a single spring shock absorber have better shock absorption performance, multiple spring shock absorbers are generally combined to form a combined spring shock absorber. The existing combined spring shock absorber is relatively cumbersome to assemble, and generally cannot be adjusted according to actual conditions during later use. It is also difficult to replace a single spring shock absorber later.

[0015] See also Figures 1-2In the embodiment of the utility model, a combined spring shock absorber assembly includes a bottom cylinder 1, a base 2 is fixedly connected to the lower end of the bottom cylinder 1, bottom mounting seats 14 are fixedly connected to the upper surface of the base 2 at equal distances, and the bottom mounting seats 14 are all located inside the bottom cylinder 1, and a shock absorbing spring 11 is embedded and installed inside the bottom mounting seat 14. A top cover 3 is sleeved on the upper part of the bottom cylinder 1, and a top positioning block 13 is fixedly connected to the inner bottom surface of the top cover 3. The number of the top positioning blocks 13 is equal to the number of the bottom mounting seats 14. The position of the top positioning block 13 corresponds to the position of the bottom mounting seat 14. The upper end of the shock-absorbing spring 11 is sleeved on the outer side of the top positioning block 13 directly above it. The upper surface of the base 2 is fixedly connected with a rod sleeve 8, and the rod sleeve 8 is located at the central axis of the bottom cylinder 1. The upper surface of the top cover 3 is provided with a groove 4, and the groove 4 is located directly above the rod sleeve 8. A knob 5 is installed inside the groove 4. The lower surface of the knob 5 is fixedly connected with a screw 7. The lower end of the screw 7 extends to the inside of the bottom cylinder 1 and is threadedly connected to the inside of the rod sleeve 8.

[0016] Preferably, a plane bearing 6 is fixedly connected to the lower surface of the knob 5. The plane bearing 6 is an annular plane bearing with a hole in the middle. The screw 7 passes through the interior of the plane bearing 6. The lower surface of the plane bearing 6 is rough, and the bottom surface of the groove 4 is also rough. The lower surface of the plane bearing 6 and the bottom surface of the groove 4 are in contact with each other. When the knob 5 is rotated, the plane bearing 6 and the groove 4 can rub against each other, and the lower rotation of the plane bearing 6 can be avoided, so that the distance between the top cover 3 and the bottom cylinder 1 can be stably controlled. When the top cover 3 is subjected to pressure, the plane bearing 6 and the groove 4 disengage from each other without affecting the compression of the top cover 3.

[0017] Preferably, the outer surface of the bottom cylinder 1 is fixedly provided with sliding keys 9 at equal intervals, and the inner wall of the top cover 3 is provided with sliding grooves 10 at equal intervals. The number of the sliding grooves 10 is equal to and corresponds to the number of the sliding keys 9. The sliding keys 9 slide in the inside of the sliding grooves 10 respectively. When the shock absorber is used, the top cover 3 can be prevented from rotating.

[0018] Preferably, a mounting hole 12 is formed through the surface of the base 2 for mounting and fixing the spring shock absorber.

[0019] The working principle of the utility model is as follows: when the combined spring shock absorber is used, the base 2 can be fixed by passing the bolt through the mounting hole 12, and then the upper surface of the top cover 3 can be contacted with the other side of the equipment that needs shock absorption, and the shock absorbing spring 11 can be compressed by squeezing the top cover 3, so as to achieve the effect of shock absorption, and the state of the shock absorbing spring 11 can be adjusted by turning the knob 5, so as to change the overall stress condition of the shock absorber, and the screw rod 7 can be rotated inside the rod sleeve 8 by turning the knob 5, and the distance between the top end of the bottom cylinder 1 and the inner bottom surface of the top cover 3 can be adjusted, and because the plane bearing 6 and the groove 4 are in contact through the rough surface, when the knob 5 is turned, the plane bearing 6 does not rotate, and when the top cover 3 is pressed down, the plane bearing 6 and the groove 4 are disengaged from each other, and will not cause obstruction to the downward movement of the top cover 3, and when the top cover 3 moves upward, the plane bearing 6 can form an obstruction to the top cover 3, and the upward movement of the top cover 3 is limited.
