Description

Technical Field

[0001] The utility model relates to the technical field of shock absorbers, in particular to a shock absorber with adjustable springs. Background Art

[0002] A shock absorber is a mechanical structure that, through its own compression and stretching movements, utilizes the flow resistance of oil (or other damping materials such as gas) to consume vibration energy, thereby mitigating and absorbing the impact vibrations transmitted from the road surface. It is widely used in fields such as automobiles, ships, aviation, industrial machinery, and construction projects.

[0003] In some existing shock absorbers, adjusting the spring compression requires manually disassembling or adjusting multiple components, which not only increases the complexity and time cost of adjustment but may also have a certain impact on the overall performance of the shock absorber, resulting in many inconveniences. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a shock absorber with adjustable springs, which can facilitate the adjustment of the springs through this device to solve the problem that it is inconvenient to adjust the springs in the prior art.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0007] Preferably, a plurality of notches one are provided at the upper end of the movable plate, a plurality of notches two are provided at the lower end of the upper seat, and the upper and lower ends of the spring are respectively located inside the notches one and the notches two.

[0008] Preferably, two sliding grooves are provided inside the base, and the sliding grooves are slidably connected to the sliding plates.

[0009] Preferably, a plurality of through grooves are provided inside the base, the upper and lower ends of the through grooves are respectively communicated with the groove and the sliding groove, and the through grooves are slidably connected to the connecting plates.

[0010] Preferably, a rod body is slidably connected through one side of the base, the rod body is threadedly connected through the sliding plate, and a rotating block is fixedly connected to the end of the rod body.

[0011] Preferably, the damping structure includes a cylindrical column and a vertical rod. The vertical rod is slidably connected to the cylindrical column. The lower end of the cylindrical column is fixedly connected to the upper end of the base, and the upper end of the vertical rod is fixedly connected to the lower end of the upper seat.

[0012] Compared with the prior art, the advantages of the present utility model are as follows:

[0013] 1. The operator places the two ends of the spring into the first notch and the second notch respectively, and then rotates the rotating block to make the rod body rotate, so that the two sliding plates slide relative to each other. The sliding plates drive the connecting seat to slide, causing the connecting plate to rotate between the connecting block and the connecting seat, pushing the connecting block, and at the same time the connecting block pushes the movable plate to slide upward by an appropriate distance to install the spring. By simply rotating the rotating block, the position of the movable plate can be automatically adjusted, providing sufficient space for the installation of the spring, thus greatly simplifying the installation steps.

[0014] 2. When the spring needs to be adjusted, rotate the rotating block to make the rod body rotate, so that the two sliding plates slide relative to each other. The sliding plates drive the connecting seat to slide, causing the connecting plate to rotate between the connecting block and the connecting seat, pushing the connecting block, and at the same time the connecting block pushes the movable plate to slide upward, thereby compressing and adjusting the spring. By controlling the sliding distance of the sliding plate, the rising height of the movable plate can be accurately controlled, so as to achieve fine adjustment of the spring compression amount.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0021] Referring to Figures 1-4 , a spring-adjustable shock absorber includes a base 1. A groove 2 is provided at the upper end of the base 1. A movable plate 3 is slidably connected inside the groove 2. A plurality of connecting blocks 11 are fixedly connected to the lower end of the movable plate 3. Two sliding plates 9 are slidably connected inside the base 1. A plurality of connecting seats 10 are fixedly connected to the upper ends of the sliding plates 9. A connecting plate 12 is hinged between the connecting blocks 11 and the connecting seats 10; an upper seat 5 is provided at the upper end of the base 1. A plurality of damping structures are provided between the upper seat 5 and the base 1. A plurality of springs 7 are provided between the lower end of the upper seat 5 and the upper end of the movable plate 3. The operator places the spring 7 in the space reserved between the movable plate 3 and the upper seat 5. The sliding plate 9 drives the connecting seat 10 to slide, so that the connecting plate 12 rotates between the connecting block 11 and the connecting seat 10, pushing the connecting block 11. At the same time, the connecting block 11 pushes the movable plate 3 to slide upward by an appropriate distance to install the spring 7, thereby reducing the installation difficulty and enabling the operator to more easily complete the installation work. When the spring 7 needs to be adjusted, the sliding plate 9 drives the connecting seat 10 to slide, so that the connecting plate 12 rotates between the connecting block 11 and the connecting seat 10, pushing the connecting block 11. At the same time, the connecting block 11 pushes the movable plate 3 to slide upward, thereby compressing and adjusting the spring 7.

[0022] A plurality of notches 4 are provided at the upper end of the movable plate 3. A plurality of notches 6 are provided at the lower end of the upper seat 5. The upper and lower ends of the spring 7 are respectively located inside the notches 4 and the notches 6, and the upper and lower ends of the spring 7 are limited by the notches 4 and the notches 6.

[0023] Two sliding grooves 8 are provided inside the base 1. The sliding grooves 8 are slidably connected to the sliding plates 9, and the sliding plates 9 are guided and limited by the sliding grooves 8.

[0024] A plurality of through grooves 13 are provided inside the base 1. The upper and lower ends of the through grooves 13 are respectively communicated with the groove 2 and the sliding groove 8. The through grooves 13 are slidably connected to the connecting plate 12, and the connecting plate 12 is received by the through grooves 13.

[0025] A rod 14 is slidably connected through one side of the base 1. The rod 14 is threadedly connected through the sliding plates 9. A rotating block 15 is fixedly connected to the end of the rod 14. A left-right thread is provided on the side wall of the rod 14. The two sliding plates 9 correspond to the left-right thread. By rotating the rotating block 15, the rod 14 rotates, so that the two sliding plates 9 slide relative to each other.

[0026] The damping structure includes a cylinder column 16 and a vertical rod 17. The vertical rod 17 is slidably connected to the cylinder column 16. The lower end of the cylinder column 16 is fixedly connected to the upper end of the base 1. The upper end of the vertical rod 17 is fixedly connected to the lower end of the upper seat 5. Hydraulic oil is provided inside the cylinder column 16. When the vertical rod 17 moves rapidly inside the cylinder column 16, the hydraulic oil will be quickly squeezed, thereby generating a damping force.

[0027] In the present utility model, the operator places the two ends of the spring 7 inside the notch one 4 and the notch two 6 respectively, and then rotates the rotary block 15 to rotate the rod body 14, so that the two sliding plates 9 slide relatively. The sliding plate 9 drives the connecting seat 10 to slide, so that the connecting plate 12 rotates between the connecting block 11 and the connecting seat 10, pushing the connecting block 11. At the same time, the connecting block 11 pushes the movable plate 3 to slide upward by an appropriate distance to install the spring 7, thereby reducing the installation difficulty and enabling the operator to complete the installation work more easily.

[0028] When it is necessary to adjust the spring 7, rotate the rotary block 15 to rotate the rod body 14, so that the two sliding plates 9 slide relatively. The sliding plate 9 drives the connecting seat 10 to slide, so that the connecting plate 12 rotates between the connecting block 11 and the connecting seat 10, pushing the connecting block 11. At the same time, the connecting block 11 pushes the movable plate 3 to slide upward, thereby compressing and adjusting the spring 7.
