Description

Technical Field

[0001] This utility model relates to the field of vibration damper technology, specifically a vibration damper for reducing noise. Background Technology

[0002] Detailed introduction of shock absorbers: Working principle: When the vehicle frame (or body) and axle are subjected to vibration and relative motion occurs, the piston inside the shock absorber moves up and down. The oil in the shock absorber chamber repeatedly flows from one chamber to another through different orifices. The friction between the orifice wall and the oil and the internal friction between oil molecules form a damping force on the vibration, which converts the vehicle's vibration energy into oil heat energy, which is then absorbed by the shock absorber and dissipated into the atmosphere.

[0003] Regarding the above-mentioned technical solutions, existing vibration dampers are prone to generating noise during use. Excessive noise can affect the user experience and thus the performance. Furthermore, their fixed installation positions make it difficult to match with the reserved installation holes, which also affects the performance.

[0004] Therefore, this utility model provides a vibration damper to reduce noise, in order to solve the above-mentioned problems. Utility Model Content

Pull ring 27 is fixedly installed on one side of movable plate 24. Noise reduction component 2 also includes anti-slip sleeve 28, which is disposed on one side of pull ring 27. Noise reduction component 2 also includes slide rod 29, which is fixedly installed on one side of sound absorption plate 22. Movable plate 24 and slide rod 29 are slidably connected. Positioning component 3 is fixedly installed on both sides of sound absorption plate 22. Positioning component 3 includes positioning block 31 and positioning groove 32. Positioning block 31 is fixedly installed on both sides of sound absorption plate 22. Positioning groove 32 is opened on one side of fixed plate 21.

[0032] In this embodiment, firstly, pulling the pull ring 27 can compress the spring 23 by moving the plate 24, and then the positioning block 31 and the positioning groove 32 are engaged together. After that, releasing the pull ring 27 can allow the spring 23 to reset the moving plate 24, so that the moving plate 24 can drive the locking rod 25 to engage with the locking groove 26, so that the sound-absorbing plate 22 can have a good sound insulation effect on the vibration damper body 1, and also make the vibration damper body 1 quieter to use.

[0033] Reference Figures 1 to 4In one aspect of this embodiment, a positioning component 3 is fixedly installed at the bottom of the shock absorber body 1. An adjustment mounting component 4 is threadedly connected to one side of the positioning component 3. The adjustment mounting component 4 includes a threaded rod 41 and a movable plate 42.

The position of the second movable plate 42 can be adjusted according to actual needs. Then, the whole can be fixed by bolts through the connecting groove 43, and the fixing is simple and convenient.

[0035] Working principle: First, pulling the pull ring 27 will cause the spring 23 to retract by squeezing the moving plate 24. Then, the positioning block 31 and the positioning groove 32 will be engaged together. After that, releasing the pull ring 27 will allow the spring 23 to reset the moving plate 24, so that the moving plate 24 can drive the locking rod 25 to engage with the locking groove 26. This allows the sound-absorbing plate 22 to have a good sound insulation effect on the vibration damper body 1, and also makes the vibration damper body 1 quieter to use.

[0036] Then, turning the knob 46 can drive the threaded rod 41 to rotate on one side of the positioning component 3, so that the second movable plate 42 can slide inside the stabilizing groove 45 through the stabilizing block 44, so that the position of the second movable plate 42 can be adjusted according to actual needs. Then, the whole can be fixed by bolts through the connecting groove 43, and the fixing is simple and convenient.
