Description

Technical Field

[0001] The utility model relates to the technical field of door and window rubber strips, and more specifically to a corner rubber strip which is convenient for processing diagonal corners. Background Art

[0002] Sealing strips are made of rubber and used for product sealing. They are mainly used in automobiles, machinery, doors and windows, etc. Sealing strips can prevent leakage or intrusion of internal and external media (rain, air, dust, etc.), and can prevent or reduce damage caused by mechanical vibration and impact, thereby achieving sealing, sound insulation, heat insulation and shock absorption.

[0003] Corners are often encountered when sticking sealing strips on door and window frames. The usual practice is that construction workers will cut the sealing strips when encountering corners, and cut the end faces of the two strips into 45° bevels to complete the corner connection, forming multiple connections. After a long period of use, the viscosity and elasticity between the sealing strips will be disproportionate, and then they will easily fall off from the connection, resulting in a loose seal. The existing patent is a door and window corner sealing strip, and the patent announcement number CN211692109U can achieve the technical effect of firmly connecting two straight sealing strips while preventing the door and window corners from scratching clothes or the body.

[0004] However, in patent announcement number CN211692109U, one end of the first rubber strip and one end of the second rubber strip are vertically connected, and the portion where the first rubber strip and the second rubber strip are connected needs to be cut into a 45° inclined surface. Usually, the corner inclined surface needs to be cut manually by staff. Since the cutting of the angle requires a certain degree of precision, it is necessary to use tools to measure and then draw lines, and finally cut. The operation is very inconvenient. Therefore, we propose a corner rubber strip that is easy to process diagonally to solve the above-mentioned problems. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of the utility model is to provide a corner rubber strip that is easy to process diagonally. It can be done by installing a corner joint at the end of the rubber strip body, and then using a blade to fit the cutting bevel of the corner joint to cut the rubber strip body, so that the cutting part of the rubber strip body forms a 45° bevel section, which is convenient for rapid processing of the diagonals of the rubber strip body.

[0006] To solve the above problems, the utility model adopts the following technical solutions.

[0007] A corner rubber strip convenient for processing diagonal corners comprises a rubber strip body, the inner side of the rubber strip body is provided with a hollow structure, a partition is provided on the inner side of the rubber strip body, and both sides of the partition are provided with rubber storage cavities;

[0008] A corner joint is installed at the end of the rubber strip body, and a cutting slope is arranged at one end of the corner joint close to the end of the rubber strip body. The surface of the cutting slope is respectively provided with a bump and a groove, and the bump and the groove correspond to each other.

[0009] Furthermore, the length of the partition is adapted to the length of the rubber strip body, and the partition and the rubber strip body are an integrally formed structure.

[0010] Furthermore, the end portion of the glue storage cavity is filled with adhesive glue.

[0011] Furthermore, the angle between the cutting bevel and the horizontal plane at the bottom of the corner joint is 45°.

[0012] Furthermore, the portion where the cutting slope is combined with the rubber strip body is a cutting line.

[0013] Furthermore, the corner joint is made of aluminum alloy, and the protrusion and the groove are an integrally formed structure with the corner joint.

[0014] Furthermore, an embedded structure is formed between the protrusion and the groove.

[0015] Compared with the prior art, the advantages of the present invention are:

[0016] (1) In this scheme, a corner joint is installed at the end of the rubber strip body, and then the rubber strip body is cut by using a blade to fit the cutting bevel of the corner joint, so that the cutting part of the rubber strip body forms a 45° bevel cut surface, which facilitates the rapid processing of the diagonal corners of the rubber strip body.

[0017] (2) In this scheme, a proper amount of adhesive is injected into the adhesive storage cavity at one end of the beveled surface of the rubber strip body, and the ends of the two rubber strip bodies to be spliced ​​with the corner joints are connected to each other. At the same time, the accuracy of the connection between the corner joints can be ensured by connecting the protrusions with the grooves, thereby facilitating the bonding between the diagonal beveled surfaces of the rubber strip bodies.
