[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] (1) The backrest angle bracket of the present application is suitable for cabinets, especially for fixing the cover and decoration of skirting boards to the bottom of wardrobes. A plug-in structure is provided on the first fixing plate of the backrest angle bracket and the backrest angle bracket is connected to the cabinet bottom plate through the plug-in structure, and is fixedly connected to the skirting board through the second fixing plate. There is no need to use screws to fix the connection as in the past for installing skirting boards on cabinets, which can not only reduce the installation cost, but also achieve the purpose of quickly installing skirting boards on the bottom of the cabinet. In addition, the plug-in structure is clamped with the connecting hole of the cabinet bottom plate through the elastic buckles provided around it, thereby improving the stability of the connection between the backrest angle bracket and the cabinet bottom plate and preventing the backrest angle bracket from falling off.

[0035] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0036] like Figure 1-6 As shown, a backrest angle bracket 03 for connecting a skirting 02 with a cabinet 01 is used to facilitate the skirting 02 to be fixedly installed on the bottom of the cabinet 01 by using the backrest angle bracket 03. The backrest angle bracket 03 of the embodiment of the present application includes a seat body 10 and a plug-in structure 20. The seat body 10 and the plug-in structure 20 can be integrally formed by an injection mold, thereby improving the production and processing efficiency and quality of the backrest angle bracket 03. Among them, the seat body 10 has a first fixed plate 101 and a second fixed plate 102. The first fixed plate 101 and the second fixed plate 102 are integrally formed into an L-shaped bending shape. The first fixed plate 101 is set in the horizontal direction, and the second fixed plate 102 is set in the vertical direction. Moreover, the inner side surface of the first fixed plate 101 and the inner side surface of the second fixed plate 102 are fixedly connected by a reinforcing plate 103 to increase the structural strength of the seat body 10.

[0037] The plug-in structures 20 are arranged on the surface of the first fixed plate 101 in a plurality, and the number of the plug-in structures 20 is the same as the number of the reinforcing plates 103. Since the plug-in structures 20 are arranged on the outer surface of the first fixed plate 101 and the reinforcing plates 103 are arranged on the inner surface of the first fixed plate 101, in order to further improve the strength of the connection structure between the reinforcing seat body 10 and the plug-in structures 20, the reinforcing plates 103 and the plug-in structures 20 are arranged one-to-one on the inner and outer surfaces of the first fixed plate 101.

[0038] The plug-in structure 20 has a base end 201 and a plug-in end 202. The plug-in structure 20 is vertically fixedly connected to the outer surface of the first fixed plate 101 through the base end 201. The plug-in end 202 of the plug-in structure 20 is set to a round cake shape, and chamfers are also set around the end of the plug-in end 202. By setting the plug-in end 202 to a round cake shape with chamfers, it plays a role in reinforcing the structure and introduction, which is used to reinforce the entire plug-in structure 20 and facilitate the plug-in end 202 to be inserted into the connecting hole of the cabinet bottom plate 011.

[0039] At least two elastic buckles 203 are arranged around the plug-in end 202 of the plug-in structure 20, and the two elastic buckles 203 are symmetrically arranged with respect to the center of the end face of the plug-in end 202. The ends of the elastic buckles 203 face the base end 201 of the plug-in structure 20 and can generate an outward elastic force when pressed by an external force. Therefore, when the plug-in end 202 is plugged into the connection hole of the cabinet bottom plate 011, the plug-in end 202 clamps the connection hole through the elastic buckle 203, and the inner wall of the connection hole presses the elastic buckle 203 of the plug-in end 202. At the same time, the elastic buckle 203 clamps the inner wall of the connection hole through outward elastic rebound to prevent the plug-in structure 20 from loosening.

[0040] An adhesive layer 104 is provided on the outer side surface of the second fixed plate 102, and is fixedly connected to the skirting line 02 through the adhesive layer 104. The skirting line 02 is glued to the outer side surface of the second fixed plate 102, thereby covering the bottom of the cabinet 01, which can not only decorate the bottom of the cabinet 01, but also prevent debris and other garbage on the ground from being kicked into the bottom of the cabinet 01, creating a sanitary dead corner.

[0041] In this way, the backrest angle code 03 is connected to the cabinet bottom plate 011 by setting a plug-in structure 20 on the first fixed plate 101, and is fixedly connected to the skirting board 02 through the second fixed plate 102. There is no need to use screws to fix the connection as in the previous installation of the skirting board 02 on the cabinet 01, which can not only reduce the installation cost, but also achieve the purpose of quickly installing the skirting board 02 at the bottom of the cabinet 01; in addition, the plug-in structure 20 is clamped with the connecting hole of the cabinet bottom plate 011 through the elastic buckle 203 arranged around it, so as to improve the connection stability between the backrest angle code 03 and the cabinet bottom plate 011 and prevent the backrest angle code 03 from falling off; by using the snap-in connection of the plug-in structure 20 on the first fixed plate 101 and the adhesion of the second fixed plate 102, the fixed connection area of ​​the cabinet bottom plate 011 and the skirting board 02 can be increased, and the cabinet bottom plate 011 and the skirting board 02 can be avoided from bending and deformation.

[0042] One end of the elastic buckle 203 is integrally formed with the periphery of the plug end 202, and a plurality of gripping teeth 2031 are arranged on the outer side of the other end (the end) of the elastic buckle 203, and the gripping teeth 2031 protrude from the outer surface of the end of the elastic buckle 203, and the shape of the gripping teeth 2031 gradually tapers from the end to the middle of the elastic buckle 203. Therefore, when the elastic buckle 203 rebounds and clamps the inner wall of the connection hole of the cabinet bottom plate 011, the elastic buckle 203 is also pressed into the wood of the inner wall of the connection hole through the gripping teeth 2031, thereby strengthening the gripping force of the connection hole between the elastic buckle 203 and the cabinet bottom plate 011, and further improving the connection stability and anti-slip effect of the plug-in structure 20 and the cabinet bottom plate 011.

[0043] A plurality of convex ribs 204 are arranged around the plug-in structure 20 , and an arc-shaped recess 205 is provided between two adjacent convex ribs 204 to improve the structural strength between the two adjacent convex ribs 204 . By providing a plurality of convex ribs 204 around the plug-in structure 20 , the structural strength of the plug-in structure 20 is improved. In addition, when the plug-in structure 20 is vertically arranged on the first fixed plate 101 of the base body 10, the width of the rib 204 at one end (the lower end of the rib 204) of the base end 201 is greater than the width of the rib 204 at one end (the upper end of the rib 204) of the plug-in end 202. The base end 201 with a larger and thicker width of the rib 204 is connected to the first fixed plate 101 of the base body 10, and the end with a smaller width of the rib 204 is connected to the plug-in end 202, thereby increasing the connection strength of the plug-in structure 20 on the first fixed plate 101 and with the cabinet bottom plate 011, and preventing the plug-in structure 20 from breaking due to excessive pressure from the skirting board 02.

[0044] The plug-in structure 20 of the embodiment of the present application is provided with four convex ribs 204 along its circumference, wherein two symmetrical convex ribs 204 are provided with arcuate portions 2041 on the opposite sides of the elastic buckle 203, the arcuate portions 2041 are provided at the end close to the convex rib 204 connected to the plug-in end 202, and the arcuate portions 2041 match the shape of the inner side surface of the elastic buckle 203. In this way, when the plug-in structure 20 is plugged into the connection hole of the cabinet bottom plate 011, the elastic buckle 203 is compressed toward the arcuate portion 2041 of the convex rib 204 due to pressure, and the arcuate portion 2041 provided by the convex rib 204 provides deformation space for the compression of the elastic buckle 203, thereby avoiding the problem of the elastic buckle 203 breaking due to force, and ensuring the normal compression of the elastic buckle 203.

[0045] The other two symmetrical convex ribs 204 of the plug-in structure 20 have a plurality of undercut teeth 2042 on their outer surfaces facing the plug-in direction of the plug-in structure 20, and the undercut teeth 2042 are arranged at one end close to the convex rib 204 connected to the plug-in end 202. In this way, the friction between the plug-in structure 20 and the connection hole of the cabinet bottom plate 011 is increased by the undercut teeth 2042, further improving the connection stability and anti-slip effect of the plug-in structure 20 and the cabinet bottom plate 011.

[0046] The outer surface of the convex rib 204 provided with the undercut teeth 2042 is also provided with a guide ridge 206, which is provided at an end close to the convex rib 204 connected to the base end 201. In addition, the outer peripheral surface of the plug end 202 and the outer peripheral surface of the elastic buckle 203 are both provided with an outwardly protruding guide ridge 206, and the guide ridge 206 is extended in the plugging direction of the plug structure 20. The guide ridge 206 has an axial guiding effect on the plug structure 20, and the plug structure 20 can be more easily plugged into the connection hole of the cabinet bottom plate 011 through the guide ridge 206, and the clamping and tight effect between the plug structure 20 and the connection hole is increased.

[0047] The installation method of the skirting 02 in this application is installed at the bottom of the cabinet 01 through the backrest angle code 03 as follows:

[0048] (1) First, a connection hole is opened at the position where the cabinet bottom plate 011 needs to be connected to the backrest angle bracket 03, and then the backrest angle bracket 03 inserts the plug-in structure 20 into the connection hole of the cabinet bottom plate 011 and makes the first fixing plate 101 fit flatly with the cabinet bottom plate 011;

[0049] (2) The adhesive layer 104 is pre-bonded to the outer side of the second fixing plate 102 of the backrest corner code 03. Finally, the skirting board 02 is placed vertically and its upper edge is aligned with the cabinet bottom plate 011. The inner side of the skirting board 02 is glued to the adhesive layer 104 of the second fixing plate 102 and fixedly connected to the second fixing plate 102, thereby completing the installation of the skirting board 02 and the cabinet bottom plate 011.

[0050] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
