Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of corner strips, and in particular relates to an extremely narrow corner strip that can be decorated. Background Technology
[0002] During the renovation of walls in new or existing buildings, inconsistent joints at external corners are frequently encountered. Commonly available corner trims resemble arrowheads, with panels on both sides joined together. At the corner, the trim protrudes from the panel, affecting aesthetics. Furthermore, the lack of buffer between the panels and the trim makes the joints vulnerable to damage, resulting in uneven seams. Products addressing these issues are scarce on the market. To resolve these problems, we have proposed an ultra-narrow, surface-finishable corner trim. Utility Model Content
[0003] The purpose of this utility model is to provide an extremely narrow decorative corner strip to solve the problems of low aesthetics and uneven splicing of board seams in current corner trim strips.
[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0005] This utility model is an ultra-narrow decorative corner strip, including a corner strip body. The corner strip body includes a first mounting strip and a second mounting strip. A first tapering strip extends outward from the connection between the first mounting strip and the second mounting strip. One end of the first tapering strip is connected to the second tapering strip. A plurality of mounting grooves are provided on one surface of both the first mounting strip and the second mounting strip. A mounting hole is provided on one surface of the mounting groove.
[0006] In one embodiment, the first mounting strip, the second mounting strip, the first closing strip, and the second closing strip are an integrated aluminum alloy structure.
[0007] In one embodiment, both the first and second sealing strips have a "T" shaped cross-section, and the long side of the first sealing strip is perpendicular to the long side of the second sealing strip.
[0008] In one embodiment, the long sides of the second mounting strip and the second closing strip are parallel to each other, and the long sides of the first mounting strip and the first closing strip are on the same straight line.
[0009] In one embodiment, a row of process holes is formed on the first mounting strip and the second mounting strip, and the first mounting strip and the second mounting strip are perpendicular to each other.
[0010] In one embodiment, both the first mounting strip and the second mounting strip are fixed to the keel through mounting holes.
[0011] This utility model has the following beneficial effects:
[0012] This utility model adopts a T-shaped edge-trimming structure to solve the problem of the width of the edge trim strip at the external corner of the board;
[0013] This utility model is applicable to decorative panels or ceramic slabs, tiles and other materials with thicknesses of 9mm, 10mm, 12mm and 15mm.
[0014] This utility model connects the plates on both sides of the external corner using a socket joint method, which has the following advantages compared with similar products:
[0015] a. Good sealing performance, uniform board seams;
[0016] b is detachable for easy replacement and installation;
[0017] The right-angled T-shaped design ensures stable edge finishing.
[0018] d can be laminated with corresponding board surfaces, resulting in an aesthetically pleasing appearance.
[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
[0020] To more clearly illustrate the technical solutions of the embodiments of this utility model, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.
[0021] Figure 1 This is a schematic diagram of the overall structure of an extremely narrow, decorative corner strip.
[0022] The attached diagram lists the components represented by each number as follows:
[0023] 101. First mounting strip; 102. Second mounting strip; 103. First closing strip; 104. Second closing strip; 105. Mounting groove. Detailed Implementation
[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.
[0025] Please see Figure 1As shown, this utility model is an ultra-narrow decorative corner strip, including a corner strip body, the corner strip body including a first mounting strip 101 and a second mounting strip 102, a first closing strip 103 extending outward from the connection between the first mounting strip 101 and the second mounting strip 102, a second closing strip 104 connected to one end of the first closing strip 103, a plurality of mounting grooves 105 are provided on one surface of the first mounting strip 101 and the second mounting strip 102, and mounting holes are provided on one surface of the mounting grooves 105.
[0026] Furthermore, the first mounting strip 101, the second mounting strip 102, the first closing strip 103, and the second closing strip 104 are integrated aluminum alloy structures. The corner strips manufactured in the above manner have good stability and are not easily damaged in the event of an impact. Moreover, when subjected to an impact, the torque is reduced due to the L-shaped structure formed by the cross-section, making the corner strip more stable and preventing the corner strip from loosening and causing a large piece of the decorative layer to fall off.
[0027] Furthermore, both the first closing strip 103 and the second closing strip 104 have a "T" shaped cross-section, with the long side of the first closing strip 103 and the long side of the second closing strip 104 being perpendicular to each other.
[0028] Furthermore, the long sides of the second mounting strip 102 and the second closing strip 104 are parallel to each other, and the long sides of the first mounting strip 101 and the first closing strip 103 are on the same straight line.
[0029] Furthermore, a row of process holes is respectively opened on the first mounting strip 101 and the second mounting strip 102, and the first mounting strip 101 and the second mounting strip 102 are perpendicular to each other.
[0030] Furthermore, both the first mounting strip 101 and the second mounting strip 102 are fixed to the keel through mounting holes.
[0031] It needs to be further explained that:
[0032] This utility model uses a T-shaped basic shape to form a T-shaped invisible corner strip by staggered splicing. In use, the second closing strip 104, i.e. the upper T-shaped structure, is used to fix the board on one side, and the first closing strip 103, i.e. the lower T-shaped structure, is used to fix the board on the other side. Then, the first mounting strip 101 and the second mounting strip 102 are fixed to the keel to form a unified whole and constitute the corresponding invisible corner edge closing structure.
[0033] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
