Technical Field

[0001] This utility model relates to the field of rubber pad technology, and in particular to an anti-vibration plastic pad. Background Technology

[0002] Rubber pads are a type of pad that are often installed on train bogies to dampen vibrations. When using rubber pads to cushion and dampen vibrations on train bogies, all the pressure is transferred to the rubber pads, resulting in a greater amount of pressure being transferred to the train bogies. After prolonged use, the rubber pads are prone to damage, reducing their shock resistance. Considering the above problems, it is particularly important to develop a shock-absorbing rubber pad. Utility Model Content

[0003] The main objective of this invention is to provide an anti-vibration plastic pad to solve the above-mentioned technical problems and improve the anti-vibration capability of the plastic pad.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An anti-vibration plastic pad includes a wear-resistant rubber sheet, an antibacterial rubber sheet, a high-elasticity rubber sheet, an antistatic board, and cushioning supports. The cushioning supports are fixed to the lower end of the antistatic board. The wear-resistant rubber sheet is laminated to the upper end of the antibacterial rubber sheet. The high-elasticity rubber sheet is laminated between the antibacterial rubber sheet and the antistatic rubber sheet. The high-elasticity rubber sheet includes an upper elastic rubber layer, a lower elastic rubber layer, and an air bladder. The lower end of the upper elastic rubber layer has an upper mounting cavity evenly distributed, and the upper elastic rubber layer has a lower mounting cavity evenly distributed. The upper mounting cavity and the lower mounting cavity are aligned and combined to form a mounting chamber. The air bladder is installed in the mounting chamber and abuts against the inner walls of the upper and lower mounting cavities.

[0006] As a preferred technical solution, the high-elasticity rubber plate is further provided with locking screws, the upper elastic rubber layer is provided with threaded through holes, the lower elastic rubber layer is provided with threaded grooves, the threaded through holes are aligned with the threaded grooves, and the locking screws are threadedly connected to the threaded through holes and the threaded grooves respectively.

[0007] As a preferred technical solution, the upper elastic adhesive layer is provided with a positioning post, which is disposed between two upper mounting cavities, and the lower elastic adhesive layer is provided with a positioning hole, which is disposed between two mounting cavities, with the positioning post passing through the positioning hole.

[0008] As a preferred technical solution, the buffer support foot includes a sleeve, a spring, and a support leg. The sleeve is fixed to the lower end of the antistatic plate, the spring is sleeved in the support leg, and the support leg moves within the sleeve.

[0009] As a preferred technical solution, a limiting plate is provided on the support leg, one end of the spring abuts against the limiting plate, and the other end abuts against the inner wall of the sleeve.

[0010] As a preferred technical solution, the upper surface of the wear-resistant rubber sheet is uniformly covered with raised textures.

[0011] The beneficial effects of this utility model are as follows: the above-mentioned shock-resistant plastic pad has buffer support feet to improve the shock resistance of the entire shock-resistant plastic pad; the antistatic board is made of PVC board, which gives the plastic pad antistatic ability; the high-elasticity board has high elasticity, which not only gives the plastic pad shock resistance, but also good resilience; and the wear-resistant board is made of rubber material, which not only has wear resistance, but also antistatic properties, further improving the antistatic performance of the shock-resistant plastic pad. Attached Figure Description

[0012] Figure 1 This is a structural schematic diagram of the anti-vibration plastic pad involved in this utility model. Detailed Implementation

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0014] like Figure 1 As shown, an anti-vibration plastic pad includes a wear-resistant plastic sheet 5, an antibacterial plastic sheet 4, a high-elasticity plastic sheet 3, an antistatic plate 2, and a cushioning support 1. The cushioning support 1 is fixed to the lower end of the antistatic plate 2. The wear-resistant plastic sheet 5 is laminated to the upper end of the antibacterial plastic sheet 4. The high-elasticity plastic sheet 3 is laminated between the antibacterial plastic sheet 2 and the antistatic plastic sheet 4. The cushioning support 1 is used to improve the anti-vibration performance of the entire anti-vibration plastic pad. The antistatic plate 2 is a PVC sheet, which gives the plastic pad antistatic properties. The high-elasticity plastic sheet 3 has high elasticity properties, which not only gives the plastic pad anti-vibration properties but also makes the plastic pad more durable. The pad has good resilience and can effectively reduce shock. The antibacterial rubber plate 4 is made of commercially available antibacterial plastic. Antibacterial plastic is a type of plastic that inhibits or kills bacteria, mold, yeast, algae and even viruses that contaminate plastic in the environment. It keeps itself clean by inhibiting the reproduction of microorganisms. At present, antibacterial plastic is mainly obtained by adding a small amount of antibacterial agent to ordinary plastic. The wear-resistant rubber plate 5 is made of rubber material, which not only has wear resistance but also antistatic properties, further improving the antistatic performance of the shock-resistant plastic pad.

[0015] The buffer support leg 1 includes a sleeve 11, a spring 13, and a support leg 112. A limit plate 14 is provided on the support leg 12. The spring 13 is sleeved in the support leg 12, and the support leg 12 moves within the sleeve 11. One end of the spring 13 abuts against the limit plate 14, and the other end abuts against the inner wall of the sleeve 11. When subjected to vibration, the spring 13 plays a good role in shock absorption, thereby improving the shock resistance of the support leg 12 and extending the service life of the rubber pad.

[0016] The high-elasticity rubber sheet 3 includes an upper elastic rubber layer 32, a lower elastic rubber layer 31, an air bladder 33, and locking screws 34. The upper elastic rubber layer 32 is provided with an upper mounting cavity 321, a threaded through hole 323, and a positioning post 322. The upper mounting cavities 321 are evenly distributed at the lower end of the upper elastic rubber layer 32, the positioning post 322 is disposed between two upper mounting cavities 321, and the threaded through hole 323 is disposed around the upper elastic rubber layer 32.

[0017] The lower elastic rubber layer 31 is provided with a lower mounting cavity 311, a threaded groove 312, and a positioning hole 313. The lower mounting cavities 311 are evenly distributed at the upper end of the lower elastic rubber layer 31, and are aligned with the upper mounting cavity 321. The upper mounting cavity 321 and the lower mounting cavity 311 are combined to form a mounting chamber. The airbag 33 is installed in the mounting chamber and abuts against the inner walls of the upper mounting cavity 321 and the lower mounting cavity 311. When the high elastic rubber plate 3 is compressed, the airbag 33 is compressed and deformed to reduce vibration transmission, thereby achieving a shock-resistant effect. After being decompressed, the airbag 33 quickly recovers its original shape. 12 is disposed between two lower mounting cavities 311, and threaded grooves 313 are disposed around the lower elastic adhesive layer 31. Threaded through holes 323 are aligned with threaded grooves 313. Locking screws 34 are threadedly connected to threaded through holes 323 and threaded grooves 313 respectively, thereby fixing the upper elastic adhesive layer 32 and the lower elastic adhesive layer 31. Positioning pins 322 are inserted into positioning holes 312, thereby positioning and fixing the upper elastic adhesive layer 32 and the lower elastic adhesive layer 31, ensuring that the lower mounting cavity 311 is aligned with the upper mounting cavity 321, and that the threaded through holes 323 and threaded grooves 313 are aligned.

[0018] The wear-resistant rubber sheet 5 is provided with raised textures 51, which are equidistantly arranged on the upper end of the wear-resistant rubber sheet 5. This can improve the wear resistance, reduce the folding elasticity, strengthen the structural strength of the wear-resistant rubber sheet 5, and prevent the wear-resistant rubber sheet 5 from being damaged.

[0019] The embodiments described above are merely preferred examples of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of this utility model should be included within the scope of this utility model patent application.
