[0021] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0022] like Figures 1-5 As shown, the multi-layer combined shock-absorbing and damping rubber block provided in this embodiment includes a metal layer 1, a rubber block 2, and a protective layer 3. The protective layer 3 includes an annular pad 301 and two flat pads 302. The metal layer 1 is fixedly connected to the outer side of the annular pad 301, the rubber block 2 is fixedly connected to the inner side of the annular pad 301, and the flat pads 302 are fixedly connected to the top and bottom surfaces of the rubber block 2. A spring hole 5 is provided on the upper surface of the rubber block 2, and a first spring 4 is provided in the spring hole 5. The two ends of the first spring 4 are respectively fixed to the two flat pads 302. The connection includes a buffer cavity 6 at the center of the rubber block 2, and metal wire mesh 7 inside both the annular pad 301 and the flat pad 302. The metal wire mesh 7 is a single unit. The buffer cavity 6 is a flattened sphere, and a hard rubber ball 8 is fixedly connected to the inner wall of the buffer cavity 6. The hard rubber ball 8 is a closed hollow flattened sphere. A rust-proof layer 13 is provided on the outside of the metal layer 1. The rubber block 2, the protective layer 3, and the metal layer 1 are tightly bonded together by an adhesive process. The metal layer 1 is a thin metal sheet that supports the internal structure, preventing the protective layer 3 from collapsing when the damping block is under stress. Excessive deformation; the anti-rust layer 13 is an anti-rust coating, increasing the wear resistance and corrosion resistance of the metal layer 1; the protective layer 3 is styrene-butadiene rubber, and the rubber block 2 is natural rubber. Styrene-butadiene rubber has good wear resistance, corrosion resistance, and aging resistance, while natural rubber has better elasticity. The protective layer 3 wraps around the rubber block 2, isolating it from the air and protecting it. The first spring 4 inside the rubber block 2 increases the overall elasticity of the damping block. The two ends of the first spring 4 are inserted into the flat pad 302 to fix it in place. The first spring 4 is stably extended and contracted within the spring hole 5. The metal wire mesh 7 inside the annular pad 301 and the flat pad 302 increases the overall strength of the protective layer 3. When the damping block is subjected to large vibrations and impacts, it prevents the protective layer 3 from tearing. When the rubber block 2 is squeezed, the metal layer 1 on the outside of the rubber block 2 supports the rubber block 2, causing the rubber block 2 to compress the air in the buffer cavity 6 inward. The hard rubber ball 8 is made of aging-resistant rubber and supports the buffer cavity 6, preventing excessive deformation of the rubber on the surface of the buffer cavity 6.

[0023] Furthermore, such as Figure 1 as well as Figure 2As shown, the outer side surface of the flat pad 302 is provided with a metal pad 9, the outer side surface of the metal pad 9 is fixedly connected with a metal rod 10, the outer side surface of the metal rod 10 is slidably connected with a guide plate 11, a hard rubber stick 12 is arranged between the two guide plates 11, the two ends of the hard rubber stick 12 are fixedly connected with the guide plates 11 respectively, the metal rod 10 is connected with the external device, the guide plate 11 guides the moving direction of the metal plate, so that the metal rod 10 moves in the axial direction, the hard rubber stick 12 fixedly connects the two guide plates 11, and the non-axial displacement of the metal rods 10 on the two sides is damped through the hard rubber stick 12, so that the metal rods 10 on the two sides can only be slightly angularly deviated.

[0024] As shown, Figures 1-5 The principle of the multi-layer combined shock-absorbing damping rubber block provided by the embodiment is as follows: the metal layer 1 is a thin metal sheet, which supports the internal structure, so that the protective layer 3 will not be excessively deformed when the damping block is under stress; the rust-proof layer 13 is a rust-proof plating layer, which increases the wear resistance and corrosion resistance of the metal layer 1; the protective layer 3 is a butadiene styrene rubber; the rubber block 2 is natural rubber; the butadiene styrene rubber has good wear resistance, corrosion resistance and aging resistance; the natural rubber has better elasticity; the protective layer 3 wraps the rubber block 2, so as to isolate the rubber block 2 from air and protect the rubber block 2; the No. 1 spring 4 in the rubber block 2 increases the elasticity of the damping block as a whole; the two ends of the No. 1 spring 4 are inserted into the inside of the flat pad 302 to fix the No. 1 spring 4, so that the No. 1 spring 4 can stably stretch and contract in the spring hole 5; the annular pad 301 and the metal wire mesh 7 in the inside of the flat pad 302 increase the overall strength of the protective layer 3, so as to prevent the protective layer 3 from being torn when the damping block bears a large shock and impact; when the rubber block 2 is extruded, the metal layer 1 on the outer side of the rubber block 2 supports the rubber block 2, so that the rubber block 2 extrudes the air in the buffer cavity 6 inward to deform; the hard rubber ball 8 is aging-resistant rubber, which supports the buffer cavity 6 to prevent the rubber on the surface of the buffer cavity 6 from being excessively deformed; the protective layer 3 protects the rubber block 2, the metal wire mesh 7 in the protective layer 3 increases the overall strength of the protective layer 3, so as to prevent the protective layer 3 from being torn, and the metal layer 1 supports the protective layer 3, so as to support the internal structure, so that the damping block has high strength as a whole when the damping block is under stress, thereby reducing the deformation amplitude of the damping block, and the internal rubber which is prone to aging is not in contact with air, so as to slow down the aging process of the damping block.

[0025] The metal rod 10 is connected with the external device, the guide plate 11 guides the moving direction of the metal plate, so that the metal rod 10 moves in the axial direction, the hard rubber stick 12 fixedly connects the two guide plates 11, and the non-axial displacement of the metal rods 10 on the two sides is damped through the hard rubber stick 12, so that the metal rods 10 on the two sides can only be slightly angularly deviated.
