Description

Technical Field

[0001] The utility model relates to the technical field of rubber, in particular to a tear-resistant high-strength right-angle rubber pad. Background Art

[0002] Right-angle rubber pads are a type of rubber product with a right-angle shape, usually made of multiple layers of rubber sheets that are vulcanized and bonded together. The design of this type of pad allows it to ensure uniform force while facilitating real-time buffering of gravity, thereby effectively reducing the impact of the object on the pad when it is subjected to force, and reducing the risk of breakage and damage at the right angles of the pad when it is subjected to force.

[0003] In order to make the rubber pad fit tightly against the object, a tear-resistant right-angle rubber pad is invented (see patent number: 201620130891.7 for details), which includes a pad body, wherein the body is a right-angled rectangular block, and an arc-shaped notch is set at the right angle of the inner side of the body, and damping mesh grooves are provided on the right-angled side surfaces on both sides of the arc-shaped notch. The tear-resistant right-angle rubber pad described in the utility model has an arc-shaped notch at the corner of the right-angle rubber pad, so that when the right-angle rubber pad is subjected to force and deviates to both sides, the right-angle corner will not be torn. The damping mesh grooves provided on the right-angled sides on both sides of the right-angle rubber pad effectively increase the friction of the right-angle rubber pad, so that the rubber pad fits tightly against the object.

[0004] In the process of using existing rubber pads, in order to facilitate the clip-on installation, corresponding docking holes are generally provided on the rubber pads, so that the docking holes are docked with the corresponding docking posts. However, during the stacking process, such docking holes are easily affected by thermal expansion and contraction, which increases the diameter of the docking holes, resulting in poor docking stability. In addition, during the docking connection between the docking holes and the docking posts, the docking posts will pull on the edges of the docking holes, which makes the connection ends prone to tearing, resulting in poor tearing effect and reduced utilization rate. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that in the process of using existing rubber pads, in order to facilitate the clamping installation, corresponding docking holes are generally provided on the rubber pads, so that the docking holes are docked with corresponding docking posts. However, during the stacking process, such docking holes are easily affected by thermal expansion and contraction, which increases the diameter of the docking holes, thereby making the docking stability poor. In addition, during the docking connection between the docking holes and the docking posts, the docking posts will pull on the edges of the docking holes, which makes the connection ends prone to tearing, resulting in poor tearing effect and reduced utilization rate. The utility model provides a tear-resistant high-strength right-angle rubber pad.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a tear-resistant high-strength right-angle rubber pad, comprising:

[0007] Spacers for shock absorption, vibration isolation and sealing;

[0008] Docking components, located at the four corners of the top of the pad;

[0009] A snap-on assembly, located inside the docking assembly and detachably connected to the docking assembly;

[0010] The docking components all include a limiting ring, a limiting recessed hole is provided on the top of the limiting ring, an insertion hole is provided on the bottom of the limiting ring, and a docking hole is provided at the middle position of the limiting ring. The clamping components all include a clamping column, and a clamping block is provided on the bottom of the clamping column.

[0011] As a further solution of the present invention: the clamping block is located inside the socket and is movably connected to the socket, and the clamping column is located inside the docking hole and is movably connected to the docking hole.

[0012] As a further solution of the present invention: the inner diameter of the docking hole is larger than the outer diameter of the clamping column and smaller than the outer diameter of the clamping block.

[0013] As a further solution of the present invention: the inner diameter of the docking hole is larger than the outer diameter of the clamping column and smaller than the outer diameter of the clamping block.

[0014] As a further solution of the present invention: the bottoms of the clamping posts are all arc-shaped convex surfaces.

[0015] As a further solution of the present invention: the cross-sections of the limiting rings are all arc-shaped structures.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] By providing a pad, docking assembly and clamping assembly, when in use, the raised end of the clamping block is brought into contact with the limiting recessed hole on one group of docking assemblies and squeezes the limiting ring, so that the limiting ring is deformed by force and the aperture of the docking hole is increased by force until the clamping block is plugged into the inside of the socket along the docking hole. At the same time, the limiting ring is reset under the influence of the elastic potential energy of its own rubber, and the limiting ring is clamped to the outside of the clamping column and rests on the end face of the clamping block close to the clamping column, thereby achieving a stable docking connection. At the same time, since the cross-section of the limiting ring is an arc-shaped structure similar to the effect of an arch, the bearing capacity of the stressed end is greater when it is subjected to force, thereby reducing the degree of tearing caused by pulling, thereby making its tearing effect better and improving its utilization rate.
