Abstract
Description
Technical Field
[0001] This utility model relates to the field of insulating pad technology, specifically an insulating pad with good sealing performance. Background Technology
[0002] Insulating mats, also known as insulating blankets, insulating mats, insulating rubber sheets, insulating rubber mats, insulating floor mats, insulating rubber sheets, insulating gaskets, etc., are mats with high volume resistivity and resistance to electrical breakdown. They are used as tabletop or floor insulation materials in electrical distribution and other work environments.
[0003] When using current insulating pads, the connection between components is achieved through a single rubber pad structure. This results in the softer rubber pad material deforming severely under pressure, flattening and exposing gaps, leading to poor sealing. On the other hand, using a harder pad structure for connection, without deformation under pressure, fails to fill and seal the gaps, also resulting in an ineffective sealing effect. Utility Model Content
[0004] The purpose of this invention is to provide an insulating pad with good sealing performance, in order to solve the problem mentioned in the background art that, when using current insulating pads, the connection between the components is made by a single rubber pad structure. As a result, when using soft rubber pad materials for installation, severe deformation occurs under compression, causing flattening and exposing gaps, which leads to insufficient sealing. On the other hand, when using a harder gasket structure for connection, it does not deform under compression and cannot fill the gaps to form a seal, which also fails to achieve an efficient sealing effect.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] An insulating pad with good sealing performance includes a main rubber pad body. A top-fitting rubber ring is snapped onto the top surface of the main rubber pad body, and a movable top ring is snapped onto the top surface of the main rubber pad body. A snap-fitting ring groove and a movable ring groove are formed on the top surface of the main rubber pad body. A limit groove is horizontally formed on the inner side of the snap-fitting ring groove, and a positioning bottom groove is formed on the inner bottom surface of the snap-fitting ring groove. A hard plastic ring is horizontally embedded in the inner sidewall of the main rubber pad body, and top positioning holes are evenly formed on the top surface of the hard plastic ring. A top-connecting spring is fixedly engaged on the inner side of the hole. A movable bottom groove is horizontally opened at the bottom end of the movable ring groove. Vertical grooves are evenly opened on the bottom surface of the movable top ring. A top plastic ring is horizontally embedded in the inner side wall of the movable top ring. A top-connecting rubber post is inserted into the inner side of the vertical groove. A limit ring is horizontally fixedly connected to the bottom end of the movable top ring. A blocking ring is symmetrically fixed on the outer and inner sides of the top-connecting rubber ring. A stabilizing ring groove is opened on the bottom surface of the top-connecting rubber ring. An elastic rubber ring is fixedly bonded to the inner side of the stabilizing ring groove.
[0007] In a preferred embodiment of this utility model: the main rubber pad is made of soft rubber insulating material, the top rubber ring is made of soft rubber material, the bottom end of the top rubber ring is snapped into the inner side of the snapping ring groove, the bottom end of the movable top ring is snapped into the inner side of the movable ring groove, and the material of the movable top ring is consistent with that of the top rubber ring.
[0008] In a preferred embodiment of this utility model, the snap-fit ring groove and the movable ring groove are arranged in parallel to each other, and the snap-fit ring groove is located near the outer edge of the main rubber pad, while the positioning bottom groove is located at the center line of the inner bottom surface of the snap-fit ring groove.
[0009] In a preferred embodiment of this utility model: the hard plastic ring is arranged in an annular shape and is horizontally embedded in the inner side of the main rubber pad near the bottom surface. There are multiple top positioning holes, which are arranged in an annular pattern at equal intervals. The bottom end of the top connecting spring is fixed inside the top positioning hole, and the top end is connected to the bottom surface of the top plastic ring. The top connecting springs are all sleeved on the outer side of the top connecting rubber column.
[0010] In a preferred embodiment of this utility model: the movable bottom groove is horizontally positioned between the bottom end of the movable ring groove and the top surface of the hard plastic ring; the top connecting rubber column is made of hard rubber material, and the top end of the top connecting rubber column is fixedly connected to the bottom surface of the top plastic ring, while the bottom end is fixedly connected to the top surface of the hard plastic ring.
[0011] In a preferred embodiment of this utility model: the limiting ring is horizontally engaged on the inner side of the movable bottom groove, the blocking ring is symmetrically engaged on the inner side of the limiting groove, and the bottom end of the elastic rubber ring is fixedly bonded to the inner side of the positioning bottom groove, and the elastic rubber ring is made of highly elastic rubber material.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This invention utilizes a multi-layered compression and isolation mechanism. After the main rubber pad is horizontally placed between the connectors, the compression of the connectors creates a sealing effect. This compression causes the top rubber ring on the top surface to move downwards, and the elastic rubber ring on the bottom surface to deform and flatten outwards. The outward expansion of the compression seals the outer edge of the main rubber pad. The downward compression of the movable top ring on the top surface also compresses multiple top rubber columns on the bottom surface. The toughness of these top rubber columns increases the overall deformation strength of the main rubber pad, preventing it from flattening and becoming unsupported, which could lead to leaks and poor sealing. Furthermore, the internal top springs provide an outward rebound effect during connector disassembly, preventing the connectors from sticking together and becoming difficult to remove. This multi-layered compression and expansion structure improves overall sealing while the internal support structure prevents flattening during deformation, thus avoiding gap exposure and ensuring a good seal.

A top plastic ring 13 is horizontally embedded in the wall. A top-connecting rubber post 14 is inserted into the inner side of the vertical groove 12. The movable bottom groove 11 is horizontally positioned between the bottom end of the movable ring groove 5 and the top surface of the hard plastic ring 8. The top-connecting rubber post 14 is made of hard rubber material, and the top end of the top-connecting rubber post 14 is fixedly connected to the bottom surface of the top plastic ring 13, while the bottom end is fixedly connected to the top surface of the hard plastic ring 8.

[0024] The working principle of this utility model is as follows:
[0025] After the main rubber pad 1 is placed horizontally between the connectors, the compression of the connectors creates a compression isolation operation. This allows the top rubber ring 2 on the top surface to be compressed downwards, and the elastic rubber ring 18 on the bottom surface to be compressed and flattened. After the compression movement is outward, the outer edge of the main rubber pad 1 can be extended outward to seal the gap. The downward compression of the movable top ring 3 on the top surface causes the multiple top rubber pillars 14 on the bottom surface to be compressed downwards. Since the top rubber pillars 14 have a certain degree of toughness, the overall deformation strength of the main rubber pad 1 is increased, making it less likely to become flat and lack support, which would cause gaps to leak and result in poor sealing. In addition, the internal top spring 10 can create an outward rebound effect when the connectors are disassembled, making it less likely to stick together and be difficult to disassemble.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
