Description

Technical Field

[0001] This utility model relates to the field of wall corner protector technology, and in particular to a corner protector strip. Background Technology

[0002] Wall corners typically have sharp edges, which can easily cause personal injury in the event of a collision. If a hard object hits a corner, it can damage the corner, affecting its aesthetic appeal and lifespan. To prevent personal injury and corner damage, corner protectors are usually installed at wall corners.

[0003] In the conventional indoor plastering process, corner guards are usually installed using plastering methods. However, the quality of existing corner guards is not ideal, and they are prone to instability and shaking during construction. In addition, some corner guards bulge or crack after construction. In order to address these technical problems, this application proposes a new type of corner guard. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a corner protector strip. The perforated design allows mortar to enter the perforations during installation, increasing the adhesion between the corner protector strip and the dry wall or wall edge, thus improving the overall adhesion strength between the corner protector strip and the wall surface. The kraft paper is flexible, which can reduce the occurrence of bulging, cracking, and other phenomena in the corner protector strip.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A corner protector includes kraft paper, with a vinyl plastic sheet pasted to the top of the kraft paper, and a face paper pasted to the top of the vinyl plastic sheet. Both the face paper and the vinyl plastic sheet have grooves. The depth of the grooves is three-quarters of the thickness of the vinyl plastic sheet, forming two adjacent vinyl plastic sheets. The thickness of the joint between the two vinyl plastic sheets is one-quarter of the thickness of the vinyl plastic sheet. The folding angle formed by the two vinyl plastic sheets corresponds to the wall angle of the wall surface or drywall.

[0007] Furthermore, the kraft paper is wider than the vinyl plastic sheet, and the kraft paper is flexible.

[0008] Furthermore, both the face paper and the vinyl plastic sheet have multiple perforations at their top ends for mortar to enter.

[0009] Furthermore, the top and front sides of the kraft paper are provided with multiple perforations for mortar to pass through.

[0010] This utility model has the following beneficial effects:

[0011] 1. In this utility model, the perforation allows mortar to enter the perforation during installation, increasing the adhesion between the corner guard strip and the dry wall / wall edge, thus improving the overall adhesion strength between the corner guard strip and the wall surface. The kraft paper is flexible, which can reduce the occurrence of bulging, cracking, and other phenomena in the corner guard strip.

[0012] 2. In this utility model, by creating grooves on the face paper and the vinyl plastic sheet, the user can fold it according to their needs, thereby making the folding angle of the two vinyl plastic sheets correspond to the wall angle, thus improving applicability.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figure 1-3An embodiment of this utility model provides a corner protector strip, comprising kraft paper 1, characterized in that: a vinyl plastic sheet 4 is pasted to the top of the kraft paper 1, a face paper 2 is pasted to the top of the vinyl plastic sheet 4, both the face paper 2 and the vinyl plastic sheet 4 are provided with grooves 3, the depth of the grooves 3 is three-quarters of the thickness of the vinyl plastic sheet 4, forming two adjacent vinyl plastic sheets 4, the thickness of the connection between the two vinyl plastic sheets 4 is one-quarter of the thickness of the vinyl plastic sheet 4, the folding angle formed by the two vinyl plastic sheets 4 corresponds to the wall angle of the wall surface and drywall, the width of the kraft paper 1 is wider than the width of the vinyl plastic sheet 4, the kraft paper 1 is flexible, and multiple perforations 5 are opened at the top of both the face paper 2 and the vinyl plastic sheet 4 for mortar to enter, and multiple perforations 5 are opened on the front and back sides of the top of the kraft paper 1 for mortar to pass through the perforations 5;

[0020] Specifically, the groove 3 is a V-shaped groove rolled and engraved on the surface of the face paper 2 and the vinyl plastic sheet 4 by a machine cutter. Its depth is three-quarters of the thickness of the vinyl plastic sheet 4, dividing a piece of vinyl plastic sheet 4 into two parts. During construction, the user can fold the corner guard strip on both sides through the groove 3, so that the folding angle formed by the two parts of the vinyl plastic sheet 4 after folding corresponds to the wall angle. The perforation 5 allows the mortar applied to the wall to enter, thereby increasing the contact area between the corner guard strip and the wall, thereby improving the adhesion between the corner guard strip and the wall, and making the corner guard strip more firmly installed on the wall.

[0021] Working principle: In actual use, the operator can fold the corner guard according to the wall angle between the two walls, so that the included angle formed by folding the two vinyl plastic sheets 4 along the groove 3 corresponds to the wall angle. Then, the face paper 2 is brought into contact with the wall, so that the mortar applied to the wall can enter the multiple perforations 5 made on the face paper 2 and the vinyl plastic sheet 4, increasing the contact area between the mortar and the corner guard, thereby improving the adhesion strength between the entire corner guard and the wall. At this time, the kraft paper 1 will also be in contact with the wall. The kraft paper 1 itself is flexible, which can reduce the bulging and cracking of the corner guard during use. The multiple perforations 5 made on the kraft paper 1 have the same function as the perforations 5 made on the vinyl plastic sheet 4, which can facilitate the entry of mortar and increase the adhesion between the corner guard and the wall and the wall edge.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
