[0002] Panel furniture refers to furniture made of engineered wood panels. Connectors are the hardware or plastic accessories that connect the various parts of the furniture. In the production process of panel furniture, connectors are mainly used to complete L-shaped or T-shaped right-angle connections between the vertical and horizontal panels of the cabinet. At present, the furniture connectors on the market are mainly concealed connectors and corner brackets. Concealed connectors require pre-drilling holes and grooves in designated positions on the board components, which requires professional equipment and tools and is a complex process. Although corner brackets are simple and convenient to use, they are not aesthetically pleasing. Utility Model Content

[0003] This utility model provides a furniture connector that eliminates the need for drilling and grooving, has a simple structure, is easy to assemble and disassemble, and improves the overall aesthetics of furniture.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A furniture connector includes an L-shaped first connecting strip, a second connecting strip formed by rotating the first connecting strip 180° into an inverted L-shape, and a plug. The first connecting strip comprises an upper locking strip, an upper limiting platform, a mounting hole fixing plate, a lower locking strip, and a lower limiting platform. The top of the upper locking strip is a longitudinal limiting end, and the slope formed by the longitudinal limiting end tilting downwards to the left is a guide slope. The bottom of the guide slope has a reverse slope forming a groove with anti-slip texture and an engagement reinforcement surface. The cross-section of the upper locking strip is dovetail-shaped. The bottom of the engagement reinforcement surface, horizontally to the left, is the upper limiting platform. The upper part and the left side of the upper snap-fit ​​strip form an insertion cavity; the vertically downward straight plate at the left end of the upper limit platform is a mounting hole fixing plate, which has oblong front and rear adjustment mounting holes, oblong up and down adjustment mounting holes, and fixed mounting holes, arranged in a cycle; the bottom of the groove between the bottom end of the mounting hole fixing plate and the lower snap-fit ​​strip is the lower limit platform; the upper right end of the lower limit platform is the lower snap-fit ​​strip, and the top of the lower connecting strip is the longitudinal limit end A, which is formed by the guide slope, the meshing reinforcement surface, and the snap-fit ​​groove with anti-slip texture. The cross-section of the lower snap-fit ​​strip is dovetail-shaped; the opposite side of the lower limit platform is the outer surface.

[0005] The first connecting strip and the second connecting strip have the same shape.

[0006] The outer diameter of the four sides of the cap at the tail end of the plug is flush with the outer diameter of the first connecting strip and the second connecting strip after they are snapped together. The middle part of the plug is divided into two cuboids, and the outer diameter of the four sides of the cuboids matches the gap left after the first connecting strip and the second connecting strip are snapped together. The head of the plug is conical and protruding.

[0007] Furthermore, the vertical portion of the first connecting strip, from top to bottom third, consists of a dovetail-shaped upper locking strip and an upper limit platform; the remaining two-thirds of the straight plate is a mounting hole fixing straight plate; the bottom end of the mounting hole fixing straight plate, horizontally to the right, is a lower limit platform, and the right end of the lower limit platform, upward, is a dovetail-shaped lower locking strip.

[0008] Furthermore, the bottom end of the slot is a downward-facing engagement reinforcement surface, and the bottom end of the engagement reinforcement surface extends horizontally to the left to the mounting hole fixing plate, which forms an upper limit platform; the space above the upper limit platform and the left side of the upper locking strip forms an insertion groove; the connection between the upper locking strip and the upper limit platform is the axis, and the longitudinal limiting end of the upper locking strip is the symmetrical point, tilted to the left by 0.5 mm.

[0009] Furthermore, the height of the longitudinal limiting end of the upper locking strip to the horizontal plane of the upper limiting platform is equal to the height of the longitudinal limiting end of the lower locking strip to the horizontal plane of the lower limiting platform.

[0010] Furthermore, the mounting hole fixes the bottom end of the straight plate and connects to the lower snap-fit ​​strip horizontally to the right, forming a groove between them. The inner side of the bottom of the groove is the lower limit platform, and the corresponding outer side is the outer decorative surface.

[0011] Furthermore, the lower limiting platform is connected to the lower locking strip at its right end. The top of the lower locking strip is the longitudinal limiting end A. The slope formed by the limiting end tilting to the lower left is the guide slope. The bottom of the guide slope is vertically downward as the meshing reinforcement surface. The bottom of the guide slope forms a groove with anti-slip texture at an angle opposite to the guide slope. The cross-section of the lower locking strip is dovetail-shaped. The connection between the lower locking strip and the lower limiting platform is the axis, and the longitudinal limiting end of the lower locking strip is the symmetrical point, tilting to the left by 0.5 mm.

[0012] Furthermore, the plug head has a cuboid tail cap that is flush with the outer edge after being snapped shut with the first and second connecting strips; the middle part of the plug head is divided into upper and lower cuboids that match the gap left after being snapped shut with the first and second connecting strips, and the head is a conical protrusion.

[0013] In summary, this application includes the following beneficial technical effects: the main connecting strip of the connector has a simple structure, and the first and second connecting strips have the same shape; it is directly fixed with self-tapping screws through the mounting holes, eliminating the need for pre-grooving and drilling; after the first and second connecting strips are fixed in their respective designated positions, the second connecting strip fixed on the horizontal panel is aligned with the first connecting strip fixed on the vertical panel and pressed vertically downwards; or the lower locking strip at the rear end of the second connecting strip is tilted at a small angle and overlapped into the lower limiting platform at the front end of the first connecting strip, the front end of the second connecting strip is aligned and inserted, and after it is aligned with the first connecting strip at the same horizontal line, it is pushed horizontally backwards to connect; during disassembly, the horizontal panel is tapped upwards or pulled forwards, and the second connecting strip is detached from the first connecting strip, allowing one person to complete the disassembly and assembly work.

[0014] After the two connecting strips are snapped together, plugs are inserted into the gaps at the front ends of the two connecting strips. The outer decorative surfaces of the two connecting strips are flush with the upper and lower surfaces of the horizontal panel to which the second connecting strip is fixed. The cap surface of the plug is flush with the edge sealing surface at the front end of the horizontal panel. The connection between the connector and the horizontal panel is neat and smooth, which improves the overall aesthetics of the furniture. Attached Figure Description

[0022] See Figures 1-5 A furniture connector comprises an L-shaped first connecting strip 1, an inverted L-shaped second connecting strip 2 formed by rotating the first connecting strip 1 180°, and a plug 3. The first connecting strip 1 and the second connecting strip 2 have the same structural shape. The first connecting strip 1 is used to fix to the vertical panel, and the second connecting strip 2 is used to fix to the horizontal panel.

[0023] The first connecting strip 1 is composed of an upper locking strip 11, an upper limit platform 12, a mounting hole fixing plate 13, a lower connecting strip 14, and a lower limit platform 15. The top of the upper locking strip 11 is a longitudinal limiting end 111, and the slope formed by the longitudinal limiting end 111 tilting to the lower left is a guide slope 112. The bottom of the guide slope 112 has a reverse slope with anti-slip texture, forming a locking groove 113 and an engagement reinforcing surface 114. The cross-section of the upper locking strip 11 is dovetail-shaped. The bottom of the engagement reinforcing surface 114 is horizontally to the left as the upper limit platform 12. An insertion cavity is formed above the upper limit platform 12 and to the left of the upper locking strip 11; the vertically downward straight plate of the upper limit platform 12 is a mounting hole fixing plate 13, which has an oblong front-to-back adjustment mounting hole 131, an oblong up-to-down adjustment mounting hole 132, and a fixing mounting hole 133, arranged in a cyclical manner; the bottom of the groove between the bottom end of the mounting hole fixing plate 13 and the lower connecting strip 14 is the lower limit platform 15; the right end of the lower limit platform 15 is the lower connecting strip 14, and the top end of the lower connecting strip 14 is the longitudinal limiting end A 141, which is formed by the guide slope A 142, the meshing reinforcement surface A 143, and the anti-slip groove A 144. The cross-section of the lower connecting strip 14 is dovetail-shaped; the opposite side of the lower limit platform 15 is the outer surface 16.

[0024] The outer diameter of the four sides of the plug 3 and the tail cap 31 are flush with the outer diameter of the first connecting strip 1 and the second connecting strip 2 after they are snapped together. The middle part 32 of the plug is divided into two cuboids, and the outer diameter of the four sides of the cuboids matches the gap left after the first connecting strip 1 and the second connecting strip 2 are snapped together. The head 33 of the plug is conical and protrudes.

[0025] Specifically, when connecting furniture, the length of the second connecting strip 2 is obtained by subtracting the thickness of the plug cap from the length of the fixed surface of the horizontal panel. The lengths of the first connecting strip 1 and the second connecting strip 2 are the same.

[0026] See Figure 1 , Figure 2 Both the first connecting strip 1 and the second connecting strip 2 are equipped with snap-fit ​​strips and limiting platforms at the top and bottom to enhance the firmness and stability of the connectors; the elongated oval adjustment mounting hole allows for fine-tuning of the fixed position of the connecting strips, improving the installation accuracy of the connecting strips.

[0027] See Figure 3 After securing the connecting strips to the horizontal and vertical panels, place the second connecting strip 2 on the horizontal panel directly above the first connecting strip 1 on the vertical panel and press it vertically downwards. The guide slope 112 and guide slope A 142 of the first connecting strip 1 will slide and engage with the meshing reinforcing surface B 232 and guide slope BB 263 of the second connecting strip 2 in opposite directions. The rear end of the second connecting strip 2 will sink down, and the lower longitudinal limiting end B 264 of the front end of the second connecting strip 2 will overlap with the lower limiting platform 15 of the front end of the first connecting strip 1. The rear end of the second connecting strip 2 will be pushed upwards and forwards until the first connecting strip 1 and the second connecting strip 2 are engaged on the same horizontal line. Push it backwards into the horizontal panel to complete the connection. The disassembly operation can be completed by tapping the lower side of the horizontal panel vertically upwards or by pulling the horizontal panel horizontally.

[0028] See Figure 3 The longitudinal limiting ends BB 234 and B 264 of the second connecting strip 2 extend down to the upper and lower limiting platforms 12 and 15 of the first connecting strip 1, respectively; the upper limiting platform B 22 and the lower limiting platform B 25 of the second connecting strip 2 abut against the longitudinal limiting end 111 and the longitudinal limiting end A 141 of the first connecting strip 1, respectively, to complete the downward braking of the second connecting strip 2.

[0029] See Figure 3 The upper locking strips 111 of the first connecting strip 1, 113 and 114, respectively engage with the upper connecting strips 231 and 232 of the second connecting strip 2; the lower connecting strips 143 and 144 of the first connecting strip 1 engage with the engagement reinforcement surface BB 261 and the anti-slip groove BB 262 of the lower locking strip 26 of the second connecting strip 2.

[0030] See 3- Figure 5After the first connecting strip 1 and the second connecting strip 2 are connected and snapped together, there is a gap in the inner cavity. The plug 3 is inserted, and the four outer diameters of the plug cap 31 are flush with and cover the four outer diameters of the first connecting strip 1 and the second connecting strip 2 after they are snapped together. The upper and lower cuboids of the middle part 32 of the plug are matched and filled with the gap left in the inner cavity after the first connecting strip 1 and the second connecting strip 2 are connected and snapped together.

[0031] See Figure 5 The outer surfaces of the first connecting strip 1 and the second connecting strip 2 are flush with the upper and lower panels of the horizontal panel, and the plane of the plug cap 31 is flush with the front edge banding of the horizontal panel.

[0032] Working principle: The first connecting strip 1, fixed on the vertical panel, with its upper and lower limit platforms 12 and 15, and longitudinal limit ends 111 and A 141, provides braking to the longitudinal limit ends BB 234 and B 264, and the upper limit platform B 22 and lower limit platform B 25 of the second connecting strip 2, respectively, as they move downwards. The upper locking strip 11 and lower connecting strip 14 of the first connecting strip 1 engage with the upper connecting strip 23 and lower locking strip 26 of the second connecting strip 2, providing lateral tension. The anti-slip grooves 113, A 144, B 231, and BB 264 provide anti-slip support. After the 262 interlocking mechanism engages, it prevents the second connecting strip 2 from loosening and falling off from the first connecting strip 1, and from sliding back and forth. The outer decorative surfaces 16 and 21 of the first connecting strip 1 and the second connecting strip 2 provide lateral support between the vertical and horizontal panels. The middle part 32 of the plug fills the gap between the first connecting strip 1 and the second connecting strip 2, making the interlocking between the first connecting strip 1 and the second connecting strip 2 tighter and more secure. The second connecting strip 2, fixed to the horizontal panel, is attached to the first connecting strip 1 on the vertical panel by the weight of the horizontal panel itself, which improves the connection stability and durability of the furniture.
