DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] The purpose of the present invention is to provide a tenon and a mortise and tenon joint to solve the technical problem of high production cost of existing mortise and tenon joints.

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Embodiment 1

[0035] like Figure 1-Figure 5As shown, the present embodiment provides a tenon 10, comprising a connecting block 11, at least one plug-in block 12 and at least one locking element, wherein the locking element is fixed on the plug-in block 12, and one plug-in block 12 corresponds to one locking element, the locking element is fixedly connected to the connecting block 11 and can be disassembled, and then according to actual assembly needs, the plug-in block 12 is fixed to the side wall of the connecting block 11 that needs to be connected to the mortise 20, and the plug-in block 12 is not installed on the side wall of the connecting block 11 that does not need to be connected to the mortise 20, which not only avoids the protrusion of the plug-in block 12 affecting the aesthetics, but also saves materials, thereby reducing costs, and the plug-in block 12 can be disassembled to facilitate the reuse of the plug-in block 12 and to install and fix it at different positions.

[0036] Specifically, Figure 4-Figure 5 As shown, the locking element includes two hooks 142, which are fixed on the same side wall of the plug block 12, and are connected to the connecting block 11 through the two hooks 142, thereby improving the stability of the connection; the interior of the connecting block 11 is hollow, and two through holes 113 are provided on the side wall of the connecting block 11, one hook 142 corresponds to one through hole 113, the hook 142 can extend into the connecting block 11 through the through hole 113, and be stuck at one end of the connecting block 11, thereby achieving the fixation of the connecting block 11 and the plug block 12, and the hook 142 is limited by being stuck at one end of the through hole 113, preventing the hook 142 from detaching from the connecting block 11, affecting the fixation of the plug block 12 and the connecting block 11, and further affecting the plugging of the tenon 10 and the mortise 20; the hook heads of the two hooks 142 are arranged back to back, and the two hooks The hook heads of 142 can move in the direction of approaching or moving away from each other. During installation, tweezers or other small tools are used to bring the hook heads of the two hooks 142 closer to each other until the front ends of the hook heads enter the installation grooves 112, and the plug block 12 is continued to be moved in the direction close to the connecting block 11, so that the hook heads of the hooks 142 enter the interior of the connecting block 11 through the through holes 113. Under the action of the elastic restoring force of the hooks 142, the hook heads of the hooks 142 move in the direction away from each other until they are stuck on the end of the through hole 113 away from the plug block 12, thereby achieving the locking of the hooks 142; when disassembly is required, tweezers or small tools are used to pinch the hooks 142, and the hooks 142 are moved in the direction of approaching each other, and the plug block 12 is pulled in the direction away from the connecting block 11, so that the hooks 142 are separated from the connecting block 11, thereby achieving disassembly, simple operation, and convenient installation and disassembly.

[0037] like Figure 3-Figure 4 As shown, a mounting plate 141 is fixed on one side wall of the plug block 12, and one end of the hook 142 is fixed on the mounting plate 141; a mounting groove 112 is provided on the side wall of the connecting block 11, and when the mounting plate 141 is embedded in the mounting groove 112, the hook 142 extends into the interior of the connecting block 11, and then the plug block 12 and the connecting block 11 are limited in the vertical direction through the cooperation of the mounting plate 141 and the mounting groove 112, thereby improving the connection stability.

When the tenon 10 provided in this embodiment is used in the middle position of the cabinet frame 10, that is, when both the upper and lower ends of the tenon 10 need to be connected to the mortise 20, the tenon 10 includes two insertion frames 13, and the insertion blocks 12 are four (such as Figure 1 As shown in the figure, the number of the plug blocks 12 can also be adjusted according to the specific position of the tenon 10. The connecting block 11 is a cube with openings at both ends, and two plug racks 13 are respectively fixed to the open ends of the connecting block 11. The plug racks 13 are used to plug the mortise 20 extending in the vertical direction, so as to facilitate the support of the mortise 20 in the vertical direction to assemble and form a multi-layer cabinet. Since the plug racks 13 mainly bear the longitudinal gravity, they are simpler to bear force than the plug blocks 12. Therefore, the corresponding positions on the connecting block 11 are set as openings, which can reduce the overall weight without affecting the connection stability. The connecting block 11 is hollow inside and fixed with supports. The supporting element is used to support the inner side walls of the connecting block 11, thereby ensuring the overall stability and load-bearing capacity of the connecting block 11; each plug-in block 12 is fixed to the other four side walls of the connecting block 11, and the plug-in block 12 is used to plug the mortise 20 extending in the horizontal direction, thereby supporting the mortise 20 in the horizontal direction to improve the stability of the overall connection; when the tenon 10 provided in this embodiment is located at the edge of the cabinet frame 10, according to the specific position of the tenon 10 and the connection requirements of the tenon 20, it is selected whether the plug-in block 12 needs to be connected to each surface of the tenon 10 to ensure the overall aesthetics and cost savings (such as Figure 2 shown).
