Description

Technical Field

[0001] The utility model relates to the technical field of rubber pads, in particular to a wear-resistant rubber shock-absorbing pad. Background Art

[0002] Rubber shock-absorbing pads are a common part that is characterized by both high elasticity and high viscosity. The elasticity of rubber is generated by the change in the curled molecular conformation. The interaction between rubber molecules hinders the movement of the molecular chains, thereby exhibiting the characteristics of viscous damping, so that stress and strain are often in an unbalanced state. They are often used for shock absorption in various types of equipment. Common types include rubber shock-absorbing pads, rubber air springs, rubber bearings, rubber anti-slip pads, etc.

[0003] Most of the shock-absorbing pads on the market today are round or other shaped rubber blocks installed on the supporting feet of the equipment. Their main function is to prevent slipping and provide support during driving, and they also have some shock-absorbing effect. Such devices are exposed to the external environment, and their rubber is easily damaged during use. At the same time, their shock-absorbing effect is also relatively limited. In view of this, in-depth research was conducted on the above-mentioned issues, which led to the creation of this case. Utility Model Content

[0023] A plurality of through grooves 17 are vertically penetrated inside the wear-resistant pad 16 and the buffer rubber pad 10, and the bottom end of the wear-resistant pad 16 is provided with anti-slip grooves;

[0024] Specifically, Figure 1 , Figure 2 and Figure 4 As shown, the first rubber block 6 and the second rubber block 15 are squeezed together by means of the mounting tube 5 and the base 12, so that the two wrap the fixed plate 11 in all directions. The device is connected to the equipment using the mounting platform 1, so that the vibration caused by the equipment will be transmitted to the mounting rod 2 and the fixed plate 11, and will be buffered by the first rubber block 6 and the second rubber block 15. This design can not only eliminate the longitudinal vibration, but also reduce the lateral vibration, and the shock absorbing effect is more ideal.

[0025] A support tube 3 is installed at the top of the installation tube 5, and a filling rubber ring 4 is arranged inside the support tube 3. The filling rubber ring 4 is nested in the outer wall of the installation rod 2. The outer diameter of the filling rubber ring 4 is equal to the inner diameter of the support tube 3, and the inner diameter of the filling rubber ring 4 is equal to the diameter of the installation rod 2.

[0026] Specifically, Figure 1 As shown, the filling rubber ring 4 is used to support and buffer the axial deviation of the mounting rod 2.

[0027] A plurality of positioning grooves 8 are formed at the top of the second rubber block 15, and a corresponding number of positioning posts 7 matching with the first rubber block 6 are installed at the top of the first rubber block 6, and the bottom ends of the positioning posts 7 extend to the inside of the positioning grooves 8;

[0028] Specifically, Figure 1 and Figure 4 As shown, the cooperation between the positioning column 7 and the positioning groove 8 can limit the lateral displacement of the first rubber block 6 and the second rubber block 15 , thereby improving the integrity of the first rubber block 6 and the second rubber block 15 .

[0029] A mounting platform 1 is arranged above the mounting rod 2, and a threaded rod is fixed to the top of the mounting rod 2, and the threaded rods of the mounting platform 1 are threadedly connected;

[0030] Specifically, Figure 1 As shown, such a design allows the mounting platform 1 and the mounting rod 2 to be disassembled and assembled, so as to facilitate the cooperation between the mounting rod 2 and the first rubber block 6 and the second rubber block 15 , and prevent the mounting platform 1 from blocking the installation of the first rubber block 6 .

[0031] The disassembly and assembly structure includes a fixing block 9, which is fixed to both sides of the top of the base 12, and a placement groove 25 is provided inside the fixing block 9, and a fixing box 18 is provided inside the placement groove 25, and a connecting plate 21 is fixed to one side of the fixing box 18, and one side of the connecting plate 21 is welded to the outer wall of the installation tube 5;

[0033] Specifically, Figure 1 , Figure 3 and Figure 5 As shown, the fixing box 18 is aligned with the placement groove 25 and inserted and moved to the maximum stroke. At this time, the installation tube 5 and the base 12 form a closed space, which is exactly the same as the shape and size of the rubber body formed by the first rubber block 6 and the second rubber block 15, so that the separation of the two can be limited. At the same time, since the spring telescopic rod 24 pushes the sliding block 22 to move, the card block 19 is inserted into the card groove 20, which can limit the return movement of the fixing box 18, thereby quickly connecting the installation tube 5 and the base 12 together. Conversely, the lever 23 is pulled to drive the sliding block 22 to overcome the spring telescopic rod 24 and move, and the restriction can be cancelled.
