Description

Technical Field

[0001] The utility model relates to the technical field of wall panel installation, in particular to an assembled background wall locking structure. Background Art

[0002] With the continuous improvement of living standards and the improvement of construction technology, the TV background wall is the main wall in the living room, office, and bedroom that can reflect one's own image and style. It is one of the focuses of the decoration of the living room background wall. It is usually to make up for the emptiness of the background wall of the TV area in the home space, and at the same time play a decorative role. Prefabricated decoration is currently a very common method. By pre-ordering wall panels of suitable sizes and hanging equipment, and then installing them on the wall surface, the wall panels are finally hung and moved according to the position to complete the installation. Although this type of installed wall panels simplifies the installation process, the wall panels are usually connected in a simple Z-shape. The connection strength between the wall panels is not enough, and large gaps are prone to appear, affecting the appearance. Therefore, those skilled in the art provide a prefabricated background wall locking structure to solve the problems raised in the above background technology. Utility Model Content

[0003] The purpose of the utility model is to provide an assembled background wall locking structure to solve the problems raised in the above-mentioned background technology.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A prefabricated background wall locking structure includes a wall panel unit, wherein the left and right sides of the wall panel unit are respectively provided with a male docking protrusion and a female docking groove that can dock with each other, the male docking protrusion and the female docking groove are arranged in a broken line shape, the male docking protrusion is clamped in the inside of the female docking groove, and the male docking protrusion and the female docking groove are interlocked.

[0006] As a further solution of the present invention: the length of the male docking protrusion is shorter than the depth of the female docking groove.

[0007] As a further solution of the utility model: the surfaces of the male docking protrusion and the female docking groove are both provided with inclined surfaces, the inclined surfaces are inclined, and the inclined direction is toward the direction of the female docking groove, and the two inclined surfaces abut against each other.

[0008] As a further solution of the utility model: a second docking surface is provided at the end of the female docking groove, the second docking surface is located outside the inclined surface, the second docking surface is an arc surface, and a first docking surface is provided at the end of the male docking protrusion, the first docking surface is also an arc surface.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] By setting a male docking protrusion and a female docking groove that dock with each other, and utilizing the contact and abutment between the docking surface one and the docking surface two, after a slight deformation of the docking surface two occurs, the male docking protrusion is inserted into the female docking groove. At this time, the front sides of the two wall panel monomers are tightly fitted, and the inclined surface of the male docking protrusion is also fitted with the inclined surface of the female docking groove, thereby avoiding looseness between the two wall panel monomers and ensuring that there is no gap on the front surface of the wall panel, which is more beautiful. When it needs to be dismantled afterwards, a greater force is used to make the two inclined surfaces slide against each other, so that the male docking protrusion and the female docking groove can be separated, which is also convenient for subsequent disassembly or maintenance.

[0015] See also Figures 1 to 3 In an embodiment of the utility model, an assembled background wall locking structure includes a wall panel unit 1, and the left and right sides of the wall panel unit 1 are respectively provided with a male docking protrusion 13 and a female docking groove 14 that can dock with each other. The male docking protrusion 13 and the female docking groove 14 are arranged in a broken line shape, and the male docking protrusion 13 is clamped in the inside of the female docking groove 14, and the male docking protrusion 13 and the female docking groove 14 are interlocked.

[0016] Preferably, the length of the male docking protrusion 13 is shorter than the depth of the female docking groove 14 , which can ensure that after the male docking protrusion 13 is inserted into the female docking groove 14 , the front surfaces of the two wall panel monomers 1 can be in close contact.

[0017] Preferably, the surfaces of the male docking protrusion 13 and the female docking groove 14 are both provided with inclined surfaces 15 , the inclined surfaces 15 are inclinedly arranged with the inclined direction facing the direction of the female docking groove 14 , and the two inclined surfaces 15 abut against each other.

[0018] Preferably, a docking surface 12 is provided at the end of the female docking groove 14, and the docking surface 12 is located outside the inclined surface 15, and the docking surface 12 is an arc surface. A docking surface 11 is provided at the end of the male docking protrusion 13, and the docking surface 11 is also an arc surface, which facilitates the installation of the female docking groove 14 and the male docking protrusion 13.

[0019] The working principle of the utility model is as follows: when installing the spliced ​​wall panel monomer 1, first install the expansion bolt 3 on the surface of the wall 5, then install the back-hanging long keel 2 to the end of the expansion bolt 3, and tighten it with a nut to fix the back-hanging long keel 2, then fix the back-hanging piece 4 to the inner surface of the wall panel monomer 1 at a suitable height by screws, and then hang the back-hanging piece 4 on the surface of the back-hanging long keel 2, so as to complete the installation and hanging of a wall panel monomer 1, push the wall panel monomer 1 horizontally, adjust the position of the wall panel monomer 1, and then hang the second wall panel monomer 1 on the surface of the back-hanging long keel 2 in the same way, and then push the rear wall panel monomer 1 to move toward the front wall panel monomer 1, when the male docking protrusion 1 of the rear wall panel monomer 1 3 and the female docking groove 14 of the previous block, the docking surface 11 and the docking surface 2 12 contact and abut against each other, so that the docking surface 2 12 is slightly deformed, and then the male docking protrusion 13 is inserted into the female docking groove 14. When the male docking protrusion 13 is completely inserted into the female docking groove 14, the front sides of the two wall panel monomers 1 are tightly fitted, and the inclined surface 15 at the male docking protrusion 13 is also fitted with the inclined surface 15 at the female docking groove 14, thereby avoiding looseness between the two wall panel monomers 1. When it is necessary to dismantle it afterwards, a larger force is used to make the two inclined surfaces 15 slide against each other, and the docking surface 2 12 is deformed, so that the male docking protrusion 13 and the female docking groove 14 can be separated, thereby facilitating subsequent maintenance.

[0020] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
