Description

Technical Field

[0001] This utility model relates to the field of shock absorber technology, and in particular to a high-strength silicone rubber shock absorber. Background Technology

[0002] A shock absorber is a core device that suppresses mechanical or structural vibrations by absorbing, dissipating, or isolating vibration energy. Its core principle is to use the physical properties of damping elements to convert the kinetic energy generated by vibration into heat energy or other dissipable energy, thereby weakening the transmission of vibration. In practical applications, it can not only reduce the impact damage of vibration on equipment, but also reduce noise and improve system stability. For example, automotive shock absorbers can alleviate the impact of road bumps on the vehicle body, making driving smoother; industrial machinery shock absorbers can protect the core components of motors and pumps, extending their service life.

[0003] Based on differences in damping media and structure, shock absorbers can be classified into hydraulic, pneumatic, and rubber types. Among them, rubber-type shock absorbers include high-strength silicone rubber shock absorbers. High-strength silicone rubber shock absorbers are vibration damping devices with modified silicone rubber as the core damping material. Their high strength comes from the optimized modification of the silicone rubber molecular chain, combined with fumed silica and carbon fiber reinforcement components, which significantly improves tensile strength, tear strength, and fatigue resistance. At the same time, it retains the excellent elasticity and damping characteristics of silicone rubber. During operation, it can buffer external impacts through elastic deformation and consume vibration energy through internal molecular friction, achieving the dual function of supporting loads and absorbing vibrations. However, existing silicone rubber shock absorbers do not have adjustable damping. When using equipment, it is necessary to change the silicone rubber shock absorber model, which increases the operating cost, and the application range of a single shock absorber is small. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a high-strength silicone rubber shock absorber, which aims to improve the problem of non-adjustable damping in the prior art, which requires changing the model of the rubber shock absorber back and forth.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-strength silicone rubber shock absorber, comprising an upper rubber shell, a top fixing plate slidably connected to the top of the upper rubber shell, a telescopic rod fixedly connected to the bottom of the top fixing plate, a sleeve slidably connected to the outer wall of the telescopic rod, a bottom fixing plate fixedly connected to the bottom of the sleeve, a lower rubber shell slidably connected to the outer wall of the bottom fixing plate, a shock-absorbing spring fixedly connected to the bottom of the top fixing plate, limit holes formed in the inner walls of the top and bottom fixing plates, a sliding pin slidably connected to the inner wall of the limit holes, a nut threadedly connected to the outer wall of the sliding pin, and a quick-release mechanism fixedly connected to the inner wall of the top fixing plate, the quick-release mechanism being used for quickly replacing the surface rubber shell of the equipment.

[0006] As a further description of the above technical solution:

[0007] The quick-release mechanism includes an L-shaped column, the top of which is fixedly connected to the inner wall of a top fixing plate. The inner wall of the top fixing plate has a groove, and a spring plate is fixedly connected to the inner wall of the top fixing plate. A buckle is slidably connected to the outer wall of the L-shaped column, and an upper rubber shell is fixedly connected to the outer wall of the buckle. An upper stabilizing column is fixedly connected to the bottom of the upper rubber shell, and a lower stabilizing column is slidably connected to the bottom of the upper stabilizing column. Multiple grooves are formed on the inner walls of the upper and lower stabilizing columns, and T-shaped columns are slidably connected to the inner walls of the multiple grooves.

[0008] As a further description of the above technical solution:

[0009] The inner wall of the top fixing plate is provided with a threaded hole, and the bottom of the bottom fixing plate is fixedly connected to a base plate.

[0010] As a further description of the above technical solution:

[0011] The inner wall of the bottom fixing plate is provided with a threaded hole two, and the inner wall of the base plate is provided with a threaded hole two.

[0012] As a further description of the above technical solution:

[0013] The inner wall of the base plate has a fixing hole, and the inner wall of the base plate is slidably connected with a limit pin.

[0014] As a further description of the above technical solution:

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, when replacing the damper of the shock absorber, the nut is rotated so that the nut moves downward through the sliding pin connected by the thread, so that the nut fixes the top fixing plate and compresses the nut fixedly connected to the bottom of the top fixing plate, thereby increasing the damping. The tightness of the nut can be controlled, thus achieving the effect of controlling the amount of impact force absorbed by the shock absorber without having to replace it with a different model.

[0022] 2. In this utility model, the buckle retracts inward to push the spring plate backward, causing the buckle to slide out of the L-shaped post. The buckle is then removed, allowing the upper and lower rubber shells to be removed from the inner walls of the top and bottom fixing plates. The upper and lower rubber shells are fixedly connected to the upper and lower stabilizing posts. T-shaped posts are slidably connected to the grooves on the inner walls of the upper and lower stabilizing posts. By allowing the T-shaped posts to slide out, the silicone rubber shell of the equipment can be completely removed, achieving the function of quickly replacing the shell. Attached Figure Description

[0039] Working principle: First, when it is necessary to replace the damper of the shock absorber, press the top fixing plate 3 down so that the top fixing plate 3 slides along the sliding pin 9 connected to the inner wall. Then rotate the nut 10. Because the outer wall of the nut 10 is threaded with the sliding pin 9, the nut 10 is stably downward due to the thread mechanism, so the nut 10 fixes the top fixing plate 3 and compresses the nut 10 fixed at the bottom of the top fixing plate 3, thereby increasing the damping. This allows the tightness of the nut 10 to be controlled, thus achieving the effect of controlling the amount of impact force absorbed by the shock absorber without having to replace it with a different model.

[0040] First, when the silicone rubber shell of the equipment is damaged or deformed, hold the upper rubber shell 1 and retract it inward. This causes the upper rubber shell 1 to retract the buckle 201 inward, pushing the spring plate 203 backward. The buckle 201 then slides out of the L-shaped post 202. Remove the buckle 201, and the upper rubber shell 1 can be removed from the inner wall of the top fixing plate 3. Repeat the same operation to remove the lower rubber shell 8 from the inner wall of the bottom fixing plate 4. The bottom of the upper rubber shell 1 is fixedly connected to the upper stabilizing post 205, and the top of the lower rubber shell 8 is connected to the lower stabilizing post 206. The upper stabilizing post 205 and the lower stabilizing post 206 are slidably connected to the T-shaped post 208 through the groove 207 on the inner wall of the upper stabilizing post 205 and the lower stabilizing post 206. Hold the upper rubber shell 1 and the lower rubber shell 8 upward, and the T-shaped post 208 slides out. At this point, the entire silicone rubber shell of the equipment can be removed. Then, install and fix the new shell in the reverse order, achieving the purpose of quickly replacing the shell.
