Description

Technical Field

[0001] This utility model belongs to the field of shock-absorbing pad technology, specifically relating to a damping rubber shock-absorbing pad. Background Technology

[0002] Rubber damping pads are characterized by both high elasticity and high viscosity. The elasticity of rubber arises from changes in the conformation of its coiled molecules. The interaction between rubber molecules hinders the movement of molecular chains, thus exhibiting viscous damping characteristics. Consequently, stress and strain are often in an unbalanced state. This coiled long-chain molecular structure and the relatively weak secondary forces between molecules give rubber materials unique viscoelastic properties, resulting in excellent shock absorption, sound insulation, and cushioning performance. Rubber components are widely used for vibration isolation and shock absorption because of their hysteresis, damping, and reversible large deformation characteristics. However, some existing damping pads still have certain shortcomings in practical applications, thus requiring improvement.

[0003] Chinese patent CN212266912U discloses a butyl rubber damping shock absorber, comprising a shock absorber body, fixing ears installed at the corners of the shock absorber body, and center pads installed on both sides of the middle of the shock absorber body. The shock absorber body is composed of a butyl rubber damping plate, a waterproof layer, and an anti-corrosion aluminum film layer. This invention features fixing ears at the corners of the shock absorber body, with damping pads installed on both sides of the fixing ears. The fixing ears and damping pads provide localized shock absorption and protection for the shock absorber body, reducing its compressive strength, improving its protective capability, and extending its service life. A cross-shaped cutout is installed in the middle of the shock absorber body, allowing the waterproof layer and anti-corrosion aluminum film layer to be divided into four parts. This allows for partial segmentation during replacement, facilitating replacement and reducing material waste during the replacement process.

[0004] However, although the above-mentioned technical solution supports the entire shock-absorbing pad through the fixing ears and the middle pad foot, if it is accidentally damaged during actual use, the staff will need to replace the entire shock-absorbing pad, which increases the replacement cost. The fixing ears and the middle pad foot are integrated with the shock-absorbing pad, so if any part is damaged, the shock-absorbing pad will tilt to a certain extent, which will reduce its shock absorption effect during subsequent use, thus having certain limitations in use.

Two support blocks 2 are provided on both the surface and back of the rubber damping plate 1. Bearing blocks 3 are provided above and below the rubber damping plate 1. Four connecting grooves 6 are opened inside the rubber damping plate 1. Positioning posts 7 are fixedly connected to the inner sidewall of the connecting grooves 6. Positioning plates 8 are fixedly connected to both sides of the support blocks 2. Insertion posts 9 are fixedly connected to the back of the positioning plates 8. Annular sleeves 10 are threadedly connected to the surface of the insertion posts 9. Pushing rings 11 are fixedly connected to one side of the annular sleeves 10. Two L-shaped rods 12 are fixedly connected to the surface of the pushing rings 11. Connecting sleeves 13 are fixedly connected to one end of the L-shaped rods 12, and the inner sidewall of the connecting sleeves 13 is threadedly connected to the surface of the positioning posts 7. With the support block 2, the rubber damping plate 1 provides a certain support during use. With the bearing block 3, the middle part of the rubber damping plate 1 provides a certain support effect during use, making the force more even. With the opening of the connecting groove 6, the positioning post 7 can be fixed inside. With the setting of the positioning plate 8, the plug-in post 9 can be installed and fixed. It should be noted that the surface of the plug-in post 9 penetrates the interior of the positioning post 7. The positioning post 7 is hollow. With the setting of the annular sleeve 10, the pushing ring 11 can be installed and fixed. With the setting of the pushing ring 11, the L-shaped rod 12 can be installed and fixed, which makes it easy to push the connecting sleeve 13 forward. Afterwards, the operator can rotate the annular sleeve 10 to rotate the connecting sleeve 13, and then screw it onto the surface of the positioning post 7, thereby fixing the support block 2.

[0022] Two insertion holes 4 are provided on both sides of the rubber damping plate 1. A connecting block 5 passes through the inside of the insertion hole 4, and the surface of the connecting block 5 is fixedly connected to the back of the support block 2. The insertion holes 4 allow the connecting block 5 to enter the plate, thereby initially connecting the support block 2 and the rubber damping plate 1.

[0023] Example 2:

[0024] Please see Figure 1 , Figure 2 and Figure 4 As shown, the top and bottom of the support block 2 are provided with first damping pads 14, the top of the bearing block 3 is provided with second damping pads 17, the top of the rubber damping plate 1 is provided with a waterproof layer 15, and the top of the waterproof layer 15 is provided with an anti-corrosion layer 16. The first damping pad 14 provides damping at both the top and bottom of the support block 2 during use, thus enabling the rubber damping plate 1 to function as a buffer. The second damping pad 17 provides damping for the bearing block 3. The bearing block 3 has two parts, one above the other, for easy disassembly. The waterproof layer 15 provides waterproofing for the rubber damping plate 1. The anti-corrosion layer 16 provides corrosion resistance.

Simultaneously, the operator inserts the insertion post 9 into the positioning post 7. Then, the annular sleeve 10 is rotated, causing it to move forward through the surface of the insertion post 9. The pushing ring 11 then moves forward along with it, driving the connecting sleeve 13 forward until it contacts the connecting groove 6 and is screwed onto the surface of the positioning post 7. At this point, the connecting sleeve 13 and the positioning post 7 are integrated, and the insertion post 9 is inserted into the interior of the positioning post 7. The support block 2 is then fixed. Next, the operator screws two bearing blocks 3 into the interior of the rubber damping plate 1, causing the support ring 18 to be screwed into the interior of the positioning sleeve 19, thus fixing the bearing blocks 3. The support block 2, bearing blocks 3, and rubber damping plate 1 then form a single unit, facilitating use. The waterproof layer 15 and anti-corrosion layer 16 enhance its waterproof and anti-corrosion effects, extending its service life.
