Shock-resistant arc closing-up line

Abstract

According to the anti-impact arc closing-in line, when the anti-impact arc closing-in line is subjected to external impact, the first buffer layer, the second buffer layer and the buffer mechanisms can effectively buffer impact force borne by the anti-impact arc closing-in line. Specifically, in the working process of the buffer mechanism, a first buffer layer extrudes an extrusion ball, and after the extrusion ball is subjected to extrusion force, the extrusion ball extrudes a first compression spring through a sliding rod and an extrusion plate. In the process, the extrusion plate slides along the buffer groove. And meanwhile, the extrusion ball extrudes the second compression spring through the bearing block. In other words, the first compression spring and the two second compression springs can buffer the impact force borne by the extrusion ball. In the process, the sliding column moves along the sliding hole. And due to the design of the extrusion ball, the extrusion ball can move downwards along the buffer groove after being subjected to pressure in different directions, so that the working stability of the buffer mechanism is ensured.

Description

Technical Field

[0001] This utility model relates to the field of edge trim, and in particular to impact-resistant arc edge trim. Background Technology

[0002] An external corner trim, also known as a finishing strip, edge trim, or corner strip, is a decorative molding used to cover the 90-degree convex corners of ceramic tiles. The external corner trim has a base plate as its surface, with one side forming a 90-degree fan-shaped arc. It provides a protective wrap around the corners of tiles, and is easy to install, saving labor, time, and materials. When using an external corner trim, there is no need to chamfer or bevel the tiles or stone. The trim also helps prevent injuries from collisions at the tile corners.

[0003] However, traditional corner trims, such as the technical solution protected by the patent application number 202021260960.9, entitled "Corner Trim Strip," have poor impact resistance and cannot meet the market's requirements for high impact resistance in corner trims. Utility Model Content

[0004] Therefore, it is necessary to provide an impact-resistant rounded edge trim to address the technical problem that traditional corner trims have poor impact resistance and cannot meet the market's requirements for high impact resistance in edge trims.

[0005] An impact-resistant arc-shaped end cap is provided, which has an L-shaped structure. From the outside to the inside, the impact-resistant arc-shaped end cap comprises: a first buffer layer, a support layer, a second buffer layer, an adhesive layer, and several buffer mechanisms. The first buffer layer is connected to the support layer, and the side of the support layer facing away from the first buffer layer is connected to the second buffer layer. The side of the second buffer layer facing away from the support layer is connected to the adhesive layer.

[0006] The first buffer layer has a plurality of hemispherical receiving grooves evenly formed on the side facing the support layer; the support layer has a plurality of buffer grooves evenly formed on the side facing the first buffer layer, and each buffer groove is connected to a hemispherical receiving groove.

[0007] Each of the aforementioned buffer mechanisms is housed in a corresponding buffer groove; each buffer mechanism includes a first buffer assembly and two second buffer assemblies; the first buffer assembly includes a compression ball, a sliding rod, a compression plate, and a first compression spring; the compression ball is connected to one end of the sliding rod, the end of the sliding rod away from the compression ball is connected to the compression plate, and the side of the compression plate facing away from the sliding rod is elastically connected to the bottom of the buffer groove through the first compression spring; the compression plate is adapted to the buffer groove, is housed in the buffer groove, and is slidably connected to the support layer; the compression ball is partially housed in the hemispherical receiving groove; the two second buffer assemblies are symmetrically arranged on both sides of the sliding rod;

[0008] The second buffer assembly includes a receiving block, a sliding column, a bearing block, and a second compression spring. The receiving block has an arc-shaped receiving groove that is adapted to the extrusion ball, with the extrusion ball partially housed within the arc-shaped receiving groove and abutting against the receiving block. One end of the receiving block is connected to the sliding column, and the end of the sliding column away from the receiving block is connected to the extrusion plate. The bearing block is positioned between the extrusion plate and the receiving block and connected to the inner wall of the buffer groove. A receiving groove is formed on the side of the bearing block facing the receiving block, and a sliding hole is formed in the middle region of the bottom of the receiving groove. The sliding column is adapted to the sliding hole, inserted into the sliding hole, and slidably connected to the bearing block. The second compression spring is sleeved on the sliding column. One end of the second compression spring is connected to the receiving block, and the other end of the second compression spring is connected to the bottom of the receiving groove.

[0009] In one embodiment, the first buffer layer is a rigid silicone layer.

[0010] In one embodiment, the second buffer layer is a hard rubber layer.

[0011] In one embodiment, the support layer is a PE board.

[0012] In one embodiment, the support layer is a PVC board.

[0013] In one embodiment, the extrusion plate is a circular plate structure.

[0014] In one embodiment, the sliding rod is a cylindrical structure.

[0015] In one embodiment, the sliding rod is a quadrangular prism structure.

[0016] In one embodiment, the sliding column is a cylindrical structure.

[0017] In one embodiment, the sliding column is a quadrangular prism structure.

[0018] When subjected to external impacts, the aforementioned impact-resistant arc-shaped finishing line effectively buffers the impact force through its first buffer layer, second buffer layer, and various buffering mechanisms. Specifically, during operation, the first buffer layer compresses the compression ball. Under this pressure, the compression ball then compresses the first compression spring via a sliding rod and compression plate. During this process, the compression plate slides along the buffer groove. Simultaneously, the compression ball compresses the second compression spring via a receiving block. In other words, the first compression spring and the two second compression springs buffer the impact force on the compression ball. During this process, the sliding column moves along the sliding hole. The design of the compression ball ensures that it moves downwards along the buffer groove regardless of the direction of pressure, thus guaranteeing the stability of the buffering mechanism. The aforementioned impact-resistant arc-shaped finishing line exhibits excellent impact resistance, meeting market requirements for high impact resistance in finishing lines.

[0026] Please refer to the following: Figures 1 to 2This utility model provides an impact-resistant arc-shaped edge trim 10, which has an L-shaped structure. From the outside to the inside, the impact-resistant arc-shaped edge trim 10 includes: a first buffer layer 100, a support layer 200, a second buffer layer 300, an adhesive layer 400, and several buffer mechanisms 500.

In another embodiment, the support layer 200 is a PVC board. The side of the support layer 200 facing away from the first buffer layer 100 is connected to the second buffer layer 300. The side of the second buffer layer 300 facing away from the support layer 200 is connected to the adhesive layer 400. In this embodiment, the second buffer layer 300 is a rigid rubber layer.

[0027] The first buffer layer 100 has a plurality of hemispherical receiving grooves 101 evenly distributed on the side facing the support layer 200. The support layer 200 has a plurality of buffer grooves 201 evenly distributed on the side facing the first buffer layer 100, and each buffer groove 201 is connected to a hemispherical receiving groove 101.

[0028] Each buffer mechanism 500 is correspondingly housed in a buffer groove 201. The buffer mechanism 500 includes a first buffer assembly 510 and two second buffer assemblies 520. The first buffer assembly 510 includes a compression ball 511, a sliding rod 512, a compression plate 513, and a first compression spring 514. The compression ball 511 is connected to one end of the sliding rod 512, and the end of the sliding rod 512 away from the compression ball 511 is connected to the compression plate 513. In this embodiment, the sliding rod 512 has a cylindrical structure. In another embodiment, the sliding rod 512 has a quadrangular prism structure. The side of the compression plate 513 facing away from the sliding rod 512 is elastically connected to the bottom of the buffer groove 201 via the first compression spring 514. In this embodiment, the compression plate 513 has a circular plate structure. The compression plate 513 is adapted to the buffer groove 201, is housed in the buffer groove 201, and is slidably connected to the support layer 200. The compression ball 511 is partially housed in a hemispherical receiving groove 101. Two second buffer components 520 are symmetrically arranged on both sides of the sliding rod 512.

[0029] The second buffer assembly 520 includes a receiving block 521, a sliding column 522, a bearing block 523, and a second compression spring 524. The receiving block 521 has an arc-shaped receiving groove 501, which is adapted to fit a compression ball 511. The compression ball 511 is partially housed in the arc-shaped receiving groove 501 and abuts against the receiving block 521. One end of the receiving block 521 is connected to the sliding column 522, and the end of the sliding column 522 away from the receiving block 521 is connected to the compression plate 513. The bearing block 523 is disposed between the compression plate 513 and the receiving block 521 and is connected to the inner wall of the buffer groove 201. A receiving groove 502 is formed on the side of the bearing block 523 facing the receiving block 521, and a sliding hole 503 is formed in the middle area of ​​the bottom of the receiving groove 502. The sliding column 522 is adapted to the sliding hole 503, is inserted into the sliding hole 503, and is slidably connected to the bearing block 523. In this embodiment, the sliding post 522 is a cylindrical structure. In another embodiment, the sliding post 522 is a quadrangular prism structure.

[0030] When the aforementioned impact-resistant arc-shaped taper 10 is subjected to external impact, the first buffer layer 100, the second buffer layer 300, and each buffer mechanism 500 can effectively buffer the impact force received by the impact-resistant arc-shaped taper 10. Specifically, during the operation of the buffer mechanism 500, the first buffer layer 100 compresses the compression ball 511. After being subjected to compressive force, the compression ball 511 compresses the first compression spring 514 through the sliding rod 512 and the compression plate 513. During this process, the compression plate 513 slides along the buffer groove 201. At the same time, the compression ball 511 compresses the second compression spring 524 through the receiving block 521. That is to say, the first compression spring 514 and the two second compression springs 524 can buffer the impact force received by the compression ball 511. During this process, the sliding column 522 moves along the sliding hole 503. The design of the compression ball 511 ensures that the compression ball 511 will move downward along the buffer groove 201 after being subjected to pressure from different directions, thereby ensuring the working stability of the buffer mechanism 500. The aforementioned impact-resistant rounded edge trim 10 exhibits excellent impact resistance, meeting the market's requirements for high impact resistance in edge trims.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0032] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
