[0017] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments, so as to provide a clearer understanding of the technical concept to be protected by the present invention.

[0018] like Figures 1 to 5 As shown, a quick-release connector comprises a buckle wheel 1 and a quick-release rod 2 correspondingly mounted on two furniture panels, the side wall of the buckle wheel 1 is provided with a connected slot 3 and a slide groove 4, and the thickness of the side wall of the buckle wheel 1 gradually increases from the slot 3 to the slide groove 4, one end of the quick-release rod 2 is provided with a rod head 5, the other end of the quick-release rod 2 is provided with an expansion block 6 with a gradually increasing diameter, and an expansion rod sleeve 7 is slidably connected to the quick-release rod 2, the expansion rod sleeve 7 is provided with a through groove 8, and the inner side of one end of the expansion rod sleeve 7 away from the rod head 5 corresponds to the structure of the expansion block 6.

[0019] The working principle of the quick-release connector of the utility model is achieved through the cooperation between the buckle wheel 1 and the quick-release rod 2. Figures 1 to 5 As shown, a mounting hole (not shown in the figure) is provided on the furniture board, the buckle wheel 1 is snap-connected with the mounting hole of one furniture board, the quick-loading rod 2 and the expansion rod sleeve 7 are placed in the mounting hole of the other furniture board and the rod head 5 is exposed, then the rod head 5 of the quick-loading rod 2 is inserted into the slot 3 of the buckle wheel 1, and the buckle wheel 1 is rotated to make the quick-loading rod 2 move along the slide groove 4. As the thickness of the buckle wheel 1 gradually increases, the outer side of the buckle wheel 1 will abut against the expansion rod sleeve 7 and drive the expansion rod sleeve 7 to move along the quick-loading rod 2, and the distance between the rod head 5 and the expansion rod sleeve 7 increases, so that the expansion block 6 on the quick-loading rod 2 will abut against one end of the expansion rod sleeve 7 and push one end of the expansion rod sleeve 7 outward so that the expansion rod sleeve 7 fills the mounting hole of the furniture board, completes the connection and installation of the two furniture boards, and fixes the quick-loading rod 2 to the furniture board. Compared with the traditional plate-type connecting piece, the quick-loading connecting piece can not only connect the buckle wheel 1 with the quick-loading rod 2, but also quickly connect the quick-loading rod 2 to the furniture board, thereby improving the installation efficiency of the furniture board.

[0020] Specifically, the top surface of the buckle wheel 1 is provided with a cross groove, the bottom surface of the buckle wheel 1 is provided with an eccentric arc opening 9, and the side wall of the buckle wheel 1 is provided with a tooth pattern, wherein the slot 3 has a larger slot than the slot 4, and the rod head 5 is smaller than the slot 3. Figures 1 to 5 As shown, the buckle wheel 1 is inserted into the mounting hole of the furniture board through the snap teeth, and the buckle wheel 1 is rotated by cooperating with a screwdriver and a cross slot. The arc-shaped opening 9 of the buckle wheel 1 can save costs and materials, and gradually increase the thickness of the buckle wheel 1, so that the buckle wheel 1 rotates to drive the expansion rod sleeve 7 to move.

[0021] Further, the diameter of the expansion block 6 gradually increases in the direction away from the rod head 5 and presents a truncated cone structure, wherein the length of the expansion rod sleeve 7 is less than the sum of the lengths of the quick-release rod 2 and the expansion block 6, and the through groove 8 is extended along the length direction of the expansion rod sleeve 7. Furthermore, a triangular protrusion 10 is provided in the middle of the outer side of the expansion rod sleeve 7, and a plurality of arc-shaped protrusions 11 are provided on the outer side of the expansion rod sleeve 7 on the right side of the triangular protrusion 10, such as Figures 1 to 5 As shown, the inner side of one end of the expansion rod sleeve 7 is truncated into a cone shape corresponding to the structure of the expansion block 6. When the expansion rod sleeve 7 moves along the quick-release rod 2, the expansion block 6 pushes one end of the expansion rod sleeve 7 outward. The triangular protrusion 10 and the arc-shaped protrusion 11 on the outside of the expansion rod sleeve 7 can increase the connection strength between the expansion rod sleeve 7 and the mounting hole of the furniture board.

[0022] The above are only specific embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
