[0052] To simplify the drawings, only the parts relevant to the present invention are schematically shown in each figure. They do not represent the actual structure of the product. In addition, to simplify the drawings and facilitate understanding, in some figures, only one of the components with the same structure or function is schematically depicted or labeled. In this document, "one" not only means "only one" but also supports "more than one."

[0053] The advantages and features of the present invention will become more apparent from the following description and claims.

[0054] Example

[0055] See Figures 1 to 7 , this embodiment provides a plate connection system for assembling into a cabinet. It includes: a structural member 1, the structural member 1 can be divided into a lock tongue 101 and a base 102 fixedly connected in an upper and lower manner, and the lock tongue 101 is installed on the base 102. A mounting portion 2 is used to install the structural member 1, and the base 102 of the structural member 1 is installed in the mounting portion 2. A connecting portion 3 is used to achieve a mating connection with the lock tongue 101 of the structural member 1 for fixation. A connecting plate is provided with a mounting portion 2 and / or a connecting portion 3, which is used to connect and fix different connecting plates together through the structural member 1 and the connecting groove.

[0056] See Figure 1 In this embodiment, the structural member 1 is mounted on the edge of the connecting plate. The structural member 1 primarily consists of an upper locking tongue 101 and a lower base 102, with the locking tongue 101 and base 102 fixedly connected. Two mounting holes 103 are provided on either side of the wide side of the base 102, above the portion not connected to the locking tongue 101. Self-tapping screws 104, matching these mounting holes 103, are inserted from top to bottom through the mounting holes 103, thereby bolting the structural member 1 to the mounting portion 2.

[0057] The lock tongue 101 is now described in detail. A lock tongue bevel 105 is provided on one side of the wide side of the lock tongue 101. The width of the lock tongue bevel 105 gradually decreases from the inside to the outside, and the side edges of the lock tongue bevel 105 gradually converge toward the middle. The lock tongue bevel 105 is an insertion edge, which can easily insert the lock tongue 101 into the connecting portion 3 later. The presence of the lock tongue bevel 105 also facilitates disassembly. Limiting notches 106 are provided on both sides of the long side of the lock tongue 101. The width of the two sides of the lock tongue 101 first decreases and then increases from the bottom to the top, thereby forming a limiting notch 106 at the smallest point, which can be fixed with the connecting portion 3 later.

[0058] See Figures 2 to 5Mounting portion 2 comprises a mounting groove 202. This groove 202 is machined on the edge of the connecting plate to match the dimensions of the base 102. The groove depth can be customized based on the function of the connecting plate in different locations within the cabinet. A self-tapping mounting hole 201 is defined at the bottom of the mounting groove 202. This self-tapping hole 201 is used to securely connect the structural component 1 to the mounting portion 2 with a bolt. The self-tapping screw 104 allows the structural component 1 to be adjusted in height within the mounting groove 202, thereby adjusting the tightness.

[0059] See Figure 3 When the depth of the mounting groove 202 is the same as the height of the base 102 of the structural member 1, the base 102 of the structural member 1 is located in the mounting groove 202, and the locking tongue 101 extends out of the mounting groove 202. Then, the locking tongue 101 is connected to the connecting portion 3. This connection method is mainly used to connect the cabinet side panels to the top and bottom panels.

[0060] See Figure 4 and Figure 5 When the depth of the mounting waist groove 202 is greater than or equal to the height of the structural member 1, the self-tapping screw 104 between the mounting hole 103 and the mounting guide hole 201 needs to be covered with an elastic member, which is a spring 203. The spring 203 provides elastic pressure to support the structural member 1, so that the lock tongue 101 also extends out of the mounting waist groove 202. Figure 5 By applying downward pressure to the lock tongue 101, it can be pressed into the mounting groove 202. This connection method can be used for various panel connections, including top and bottom panels, side panels, back panels, and partitions, with the lock tongue 101 being pressed in and ejected. The length of the self-tapping screw 104 drilled into the mounting guide hole 201 is adjustable and is related to the height of the lock tongue 101 protruding from the mounting groove 202.

[0061] See Figure 6 and Figure 7 The connecting part 3 includes an insertion groove 301 and a locking groove 302. The insertion groove 301 and the locking groove 302 are connected waist-shaped groove structures and are processed on the plate surface by a specific milling cutter. The lock tongue 101 of the structural part 1 is aligned with the insertion groove 301, and the lock tongue 101 is inserted into the connecting part 3. Blocking bevels 303 are provided on both sides of the locking groove 302, and the width of the blocking bevel 303 gradually increases from top to bottom. There is a transition bevel between the locking groove 302 and the insertion groove 301, and the transition bevel matches the lock tongue bevel 105. After the lock tongue bevel 105 is inserted, it fits the transition bevel to facilitate the positioning of the connecting part 3 and the structural part 1. Insert the lock tongue 101 into the connecting part 3, and then push the lock tongue 101 into the locking groove 302, so that the limiting notch 106 of the lock tongue 101 fits with the locking groove 302 to achieve locking and fixing.

[0062] See Figures 8 to 10, for example, the practical application of this embodiment is described. The top and bottom plates, side plates, and back plates are notched according to the required size, and the structural member 1 is installed. Figure 8 As shown. Structural members 1 are installed around the back panel. The symmetrical side panels are provided with connecting grooves at the connection with the back panel and the top and bottom panels. The top and bottom panels are symmetrically arranged, with structural members 1 provided at the connection with the side panels and connecting grooves provided at the connection with the back panel. Then, refer to Figure 9 , insert the lock tongue 101 of the corresponding part of each component into the insertion groove 301 of the connecting groove, assemble the cabinet, at this time the cabinet is not locked, then push the bottom plate inward to lock it, then push the back plate down to lock it, then press the lock tongue 101 of the structural member 1 on the back plate into it, and finally push the top plate in to lock it. Figure 10 As shown, the cabinet is assembled and the connector is not visible from the appearance, making the furniture more beautiful as a whole. When the cabinet needs to be disassembled, it is only necessary to insert a thin sheet into the back plate to press the lock tongue 101 down, and then disassemble it in the reverse order when installing.

[0063] Example 2

[0064] See Figures 11 to 15 This embodiment provides another implementation of the plate connection system, and its connection and setting methods are different from those of Example 1.

[0065] Compared with the embodiment 1, the structural member 1 and the mounting portion 2 of this embodiment are significantly different. Figure 11 The structural member 1 is mainly composed of an upper locking tongue 101 and a lower base 102. The locking tongue 101 is fixedly connected to the base 102. A countersunk hole 107 is provided on one side of the wide side of the base 102 and above the location not connected to the locking tongue 101, and a first connecting bolt 108 that matches the countersunk hole 107 is provided.

[0066] The lock tongue 101 is now described in detail. A beveled edge 105 is provided on one side of the wide side of the lock tongue 101. The width of the beveled edge 105 gradually decreases from the inside to the outside, and the sides of the beveled edge 105 gradually converge toward the center. The beveled edge 105 serves as an insertion edge, making it easy to insert the lock tongue 101 into the mounting portion 2 or the connecting portion 3. The beveled edge 105 also facilitates disassembly. Limiting notches 106 are provided on both sides of the long side of the lock tongue 101. The width of the two sides of the lock tongue 101 first decreases and then increases from the bottom to the top, thereby forming a limiting notch 106 at the smallest point, which can be subsequently fixed to the mounting portion 2 or the connecting portion 3. The lock tongue 101 is fixedly connected to the base 102, and one end of the lock tongue 101 extends out of the base 102. The end of the lock tongue 101 extending out of the base 102 is provided with a vertically extending screw hole 109 and a second connecting bolt 110 that matches the screw hole 109.

[0067] See Figure 12 andFigure 13 , the bottom surfaces of the bases 102 of two identical structural members 1 are connected facing each other to form a structural assembly, and then the structural assembly is installed in the mounting portion 2 for mating connection with the connecting portion 3. For the convenience of description, the structural member located above is named the first structural member, and the structural member below is the second structural member. The specific connection method is to extend the first connecting bolt 108 from the top to the bottom through the countersunk hole 107 of the first structural member, and then bolt it to the screw hole 109 of the second structural member. The second connecting bolt 110 is extended from the bottom to the top through the countersunk hole 107 of the second structural member, and then bolt it to the screw hole 109 of the first structural member, thereby connecting the first structural member and the second structural member together.

[0068] Preferably, the structural assembly further includes an elastic member, and an arcuate groove is defined at one end of the wide sides of the bases of the first and second structural members, where the countersunk hole is not defined. Specifically, the elastic member is a spring, with both ends of the elastic member disposed in the arcuate grooves of the two structural members. Due to the elastic action of the elastic member, the overall height of the structural assembly can be changed by pressing down on the first structural member.

[0069] See Figures 14 to 15 When the structural components of this embodiment are adopted, a different mounting portion 2 is adopted accordingly. The mounting portion 2 is also a mounting waist groove, and the wide side of the mounting waist groove matches the wide side of the base 103. The depth of the groove body of the mounting waist groove is greater than the height of the structural member 1 and less than the height of the structural component. The two inner side walls with long sides in the mounting waist groove are installed with limit strips 204 near the bottom of the groove. The limit strips 204 are used to match the limit notches of the lock tongue 101 inserted into the mounting waist groove, and the length of the limit strip 204 is about half the length of the mounting waist groove. Specifically, the structural component is inserted downward from the bottom where the limit strip 204 is not set in any direction. After it is fully inserted, the structural component is translated toward the limit strip 204, thereby achieving locking and fixation of the inserted structural component. After installation, the locking tongue 101 of the first structural member extends out of the mounting waist groove 202. By applying downward pressure to the locking tongue 101 of the first structural member, the locking tongue 101 of the first structural member can be pressed into the mounting waist groove 202 under the action of the elastic member. It can be used for connecting various panels, such as top and bottom panels, side panels, back panels, and partitions. The locking tongue 101 can be pressed in and popped out. Of course, the locking tongue 101 of the first structural member can also be inserted into the connecting portion 3 in the same manner as in Example 1, which will not be repeated here.

[0070] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments.
