Description

Technical Field

[0001] This utility model relates to the field of rubber shock-absorbing pad technology, and in particular to a combined rubber shock-absorbing pad. Background Technology

[0002] Rubber vibration damping pads, widely used in machinery, construction, transportation, and other fields, leverage the excellent elasticity, wear resistance, and damping properties of rubber to absorb vibration energy through their deformation. This effectively reduces vibration and noise generated by equipment operation or external impacts, thereby minimizing the adverse effects of vibration on equipment, structures, and personnel. Their structure is typically simple, often consisting of a single rubber block or a composite of rubber and a metal frame. They rely on the elastic deformation of rubber to achieve basic vibration damping. Due to their low cost and easy installation, they are widely used in various vibration damping scenarios.

[0003] However, existing rubber vibration damping pads have certain limitations in practical use: on the one hand, traditional products mostly rely on the elastic effect of a single rubber material to achieve vibration damping, with limited buffering effect and a narrow applicable load range. When faced with large or complex vibration loads, they are prone to insufficient vibration damping performance due to excessive deformation or insufficient damping, making it difficult to meet the vibration damping requirements of complex working conditions; on the other hand, their vibration damping effect is fixed and cannot be adjusted according to the vibration intensity or load changes in different scenarios. They have poor adaptability in environments with variable vibration conditions and may affect the normal operation of equipment due to insufficient or excessive vibration damping. Utility Model Content

[0004] The main purpose of this invention is to provide a combined rubber shock-absorbing pad that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a combined rubber shock-absorbing pad, including a fixing plate, a connecting bolt provided in the middle of the upper side of the fixing plate, a rubber block provided in the lower part of the fixing plate, and a buffer mechanism provided in the lower part of the rubber block; The buffer mechanism includes multiple piston rods, multiple sleeves, multiple oil discharge slots, a base, and an adjustment component. The upper ends of the multiple piston rods are fixedly connected to the inner top wall of the rubber block at equal intervals. The lower ends of the multiple sleeves are fixedly connected to the upper side of the base at equal intervals. The lower part of the piston rods is slidably connected to the inner side of the upper part of the sleeve. The multiple oil discharge slots are opened at equal intervals in the lower part of the sleeve. The upper part of the adjustment component is disposed inside the sleeve, and the lower part of the adjustment component is disposed in the middle of the base.

[0006] Preferably, the adjusting assembly includes a stop post, a threaded rod, a worm gear, a worm, a transmission rod, and an internal hexagonal knob. The left and right ends of the transmission rod are rotatably connected to the middle of the base. One end of the transmission rod passes through the middle of the base and is fixedly connected to the middle of the internal hexagonal knob. The middle portions of multiple worms are fixedly connected to the outer periphery of the transmission rod at equal intervals. The lower ends of multiple worm gears are rotatably connected to the middle of the base at equal intervals. The worm gears and worms correspond one-to-one and mesh with each other. The lower ends of multiple threaded rods pass through and are rotatably connected to the upper part of the base at equal intervals. The upper end of the threaded rod is threadedly connected to the middle of the stop post. The outer periphery of the stop post is slidably connected to the lower part of the oil unloading slot through a limiting strip.

[0007] Preferably, the base is provided with an anti-slip pad at the bottom, and the anti-slip pad is provided with anti-slip grooves at the bottom.

[0008] Preferably, the rubber block is filled with hydraulic oil, and the hydraulic oil at least seals the oil discharge groove opening.

[0009] Preferably, the outer side is covered with an elastic protective sleeve.

[0010] Preferably, a reinforcing mesh is embedded inside the wall shell of the rubber block.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. The dual buffer structure, formed by the elastic deformation of the rubber block and the flow damping of the internal hydraulic oil, combined with the sliding contact between the piston rod and the sleeve, can efficiently absorb and dissipate external vibration energy, significantly improving vibration reduction and noise reduction performance. Compared with a single rubber damping structure, the buffering effect is more stable and the applicable load range is wider. With the help of the adjustment components composed of hexagonal knob, worm gear, worm, etc., the flow area of ​​the oil unloading groove can be flexibly adjusted by rotating the knob to drive the stop rod to slide up and down, thereby adapting to the vibration load requirements under different scenarios and achieving precise control of the damping effect, solving the problem that traditional damping pads are difficult to adjust as needed.

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] like Figure 1-4 As shown, a combined rubber shock absorber includes a fixing plate 2, a connecting bolt 1 is provided in the middle of the upper side of the fixing plate 2, a rubber block 3 is provided in the lower part of the fixing plate 2, and a buffer mechanism 4 is provided in the lower part of the rubber block 3.

[0016] In this embodiment, the buffer mechanism 4 includes multiple piston rods 401, multiple sleeves 402, multiple oil discharge slots 403, a base 407, and an adjustment component. The upper ends of the multiple piston rods 401 are fixedly connected to the inner top wall of the rubber block 3 at equal intervals. The lower ends of the multiple sleeves 402 are fixedly connected to the upper side of the base 407 at equal intervals. The lower part of the piston rods 401 is slidably connected to the inner side of the upper part of the sleeves 402. The multiple oil discharge slots 403 are opened at equal intervals in the lower part of the sleeves 402. The upper part of the adjustment component is disposed inside the sleeves 402, and the lower part of the adjustment component is disposed in the middle of the base 407. The bottom of the base 407 is provided with an anti-slip pad 5, and the bottom of the anti-slip pad 5 is provided with an anti-slip groove. The rubber block 3 is filled with hydraulic oil, which at least seals the oil discharge slots 403. The outer side of the 3 is wrapped with an elastic protective sleeve, and a reinforcing mesh is embedded inside the wall shell of the rubber block 3.

[0017] Specifically, external vibrations or loads are transmitted to the fixing plate 2 through the connecting bolt 1, and then act on the rubber block 3. The rubber block 3 initially absorbs some of the vibration energy due to its own elastic deformation. At the same time, the rubber block 3 pushes the piston column 401 fixed on the inner top wall of the rubber block 3 to slide downward along the inner side of the sleeve 402, squeezing the hydraulic oil in the sleeve 402. Under pressure, the hydraulic oil will flow out through the oil discharge groove 403 at the bottom of the sleeve 402. In this process, the flow resistance of the hydraulic oil further consumes the vibration energy, achieving secondary buffering. The elastic protective sleeve on the outside of the rubber block 3 and the reinforcing mesh embedded in the wall shell enhance the structural durability. The anti-slip pad 5 with anti-slip grooves on the bottom of the base 407 can effectively prevent the shock-absorbing pad from shifting during operation, further ensuring the stability and service life during use.

[0018] In this embodiment, the adjustment assembly includes a stop post 405, a threaded rod 406, a worm gear 408, a worm 409, a transmission rod 4010, and an internal hexagonal knob 4011. The left and right ends of the transmission rod 4010 are rotatably connected to the middle of the base 407. One end of the transmission rod 4010 passes through the middle of the base 407 and is fixedly connected to the middle of the internal hexagonal knob 4011. The middle portions of multiple worms 409 are fixedly connected to the outer periphery of the transmission rod 4010 at equal intervals. The lower ends of multiple worm gears 408 are rotatably connected to the middle of the base 407 at equal intervals. The worm gears 408 and worms 409 correspond one-to-one and mesh with each other. The lower ends of multiple threaded rods 406 pass through and are rotatably connected to the upper part of the base 407 at equal intervals. The upper ends of the threaded rods 406 are threadedly connected to the middle of the stop post 405. The outer periphery of the stop post 405 is slidably connected to the lower part of the oil unloading slot 403 through a limiting strip 404.

[0019] Specifically, when the damping effect needs to be adjusted, the transmission rod 4010 is rotated by turning the hexagonal knob 4011. The worm gear 409 on the outer periphery of the transmission rod 4010 rotates synchronously. The worm wheel 408, which meshes with the worm gear 409, drives the threaded rod 406 to rotate. The threaded rod 406 drives the stop pin 405 to slide up and down along the limit bar 404 at the lower part of the oil unloading slot 403, changing the flow area of ​​the oil unloading slot 403, thereby adjusting the flow rate of hydraulic oil to adapt to different vibration load requirements. The anti-slip pad 5 at the bottom of the base 407 enhances the friction with the mounting surface through anti-slip grooves, preventing the damping pad from shifting during operation and ensuring the stability of the overall damping process.

[0020] Working principle: External vibrations or loads are transmitted to the fixed plate 2 through the connecting bolt 1, and then act on the rubber block 3. The rubber block 3 initially absorbs some of the vibration energy due to its own elastic deformation. At the same time, the rubber block 3 pushes the piston column 401 fixed on the inner top wall of the rubber block 3 to slide downward along the inner side of the sleeve 402, squeezing the hydraulic oil in the sleeve 402. Under pressure, the hydraulic oil will flow out through the oil discharge groove 403 at the bottom of the sleeve 402. In this process, the flow resistance of the hydraulic oil further consumes the vibration energy, achieving secondary buffering. When the vibration damping effect needs to be adjusted, the transmission rod 4010 is rotated by turning the internal hexagonal knob 4011. The worm gear 409 on the outer periphery of the transmission rod 4010 rotates synchronously. The worm wheel 408, which meshes with the worm gear 409, drives the threaded rod 406 to rotate. The threaded rod 406 drives the stop pin 405 to slide up and down along the limiting strip 404 at the lower part of the oil unloading groove 403, changing the flow area of ​​the oil unloading groove 403, thereby adjusting the flow rate of hydraulic oil to adapt to different vibration load requirements. The anti-slip pad 5 at the bottom of the base 407 enhances the friction with the mounting surface through anti-slip grooves, preventing the vibration damping pad from shifting during operation and ensuring the stability of the overall vibration damping process.
