DETAILED DESCRIPTION

[0025] 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.

[0026] The purpose of the present invention is to provide a mortise and tenon joint to solve the technical problem of unstable connection of existing mortise and tenon joints.

[0027] 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.

[0028] like Figure 1-Figure 5 As shown, the present invention provides a mortise and tenon connector, including a mortise 10, at least one mortise and a plurality of connecting columns 40, the mortise 10 includes a connecting block 11 and an insert block 12, the insert block 12 is fixed to the outer wall of the connecting block 11, a groove is provided at the end of the mortise, the insert block 12 can extend into the groove, thereby realizing the insertion of the mortise 10 and the mortise, and then through the mutual limitation of the mortise 10 and the mortise, it is ensured that the external support plate can be stably supported when connecting the external support plate, and a groove is provided on the side wall of the insert block 12. A first connecting hole 123 is formed, and a second connecting hole 23 is formed on the side wall of the groove at a position corresponding to the first connecting hole 123. The tenon 10 and the mortise and tenon parts are connected by the connecting column 40 which passes through the second connecting hole 23 and the first connecting hole 123 in sequence, thereby improving the stability of the connection between the tenon 10 and the mortise and tenon parts, preventing the tenon 10 and the mortise and tenon parts from sliding relative to each other after the installation is completed, thereby affecting the connection stability, and facilitating disassembly and assembly. Preferably, the connecting column 40 is a headed pin, and the first connecting hole 123 and the second connecting hole 23 are both pin holes.

[0029] Specifically, Figure 1 and Figure 2 As shown, the tenon 10 also includes two insertion racks 13, there are four insertion blocks 12, and the connecting block 11 is a rectangular parallelepiped. The two insertion racks 13 are respectively fixed on two opposite side walls of the connecting block 11, and the insertion racks 13 are used to insert the mortise and tenon extending in the vertical direction, thereby facilitating the support of the mortise and tenon in the vertical direction to assemble and form a multi-layer cabinet. Each insertion block 12 is respectively fixed on the other four side walls of the connecting block 11, and the insertion block 12 is used to insert the mortise and tenon extending in the horizontal direction, thereby facilitating the support of the mortise and tenon in the horizontal direction to improve the stability of the overall connection. However, in the mortise and tenon connector provided by the present invention, the specific structure of the tenon 10 is not limited to the above-mentioned limitation, and those skilled in the art can produce tenons 10 with different numbers of insertion blocks 12 according to the actual installation position.

[0030] The connecting block 11 is a cube with openings at both ends, and the open ends of the connecting block 11 are used to fix the plug-in rack 13. Since the plug-in rack 13 mainly bears the longitudinal gravity, its force is simpler than that of the plug-in block 12. Therefore, the corresponding position on the connecting block 11 is set as an opening, which can not only reduce the overall weight but also will not affect the connection stability. The connecting block 11 is hollow inside and is fixed with supporting elements. The supporting elements are 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.

[0031] The supporting element includes a supporting column 141 and a supporting plate 142. The supporting column 141 is located in the middle of the connecting block 11, and both ends of the supporting column 141 extend to the openings at both ends of the connecting block 11 respectively. There are four supporting plates 142, one end of the supporting plate 142 is fixed on the outer wall of the supporting column 141, and the other end of the supporting plate 142 extends to the four corners of the connecting block 11 in a direction away from and perpendicular to the axis of the supporting column 141, and the supporting plate 142 is fixedly connected to the corners of the connecting block 11. The supporting column 141 is a hollow cylinder, which not only realizes the connection between the supporting columns 141, but also does not increase the overall weight too much. The supporting columns 141 form a supporting skeleton, thereby improving the overall stability of the connecting block 11.

[0032] An auxiliary support 143 is fixed to each of the four corners of the connecting block 11, and both ends of the auxiliary support 143 extend to the two ends of the opening on the connecting block 11 respectively, and one end of the support plate 142 away from the support column 141 is fixedly connected to the auxiliary support 143. Preferably, one end of the auxiliary support 143 close to the support column 141 is an arc-shaped surface, and the auxiliary support 143, the support column 141 and the support plate 142 are integrally formed to improve the overall bonding strength.

[0034] A supporting groove 24 is also provided on the outer side wall of the transverse mortise 20, and the supporting groove 24 is used to support the edge of the external supporting plate. When the external supporting plate is a board or glass, the edge of the board or glass can be placed in the supporting groove 24, and then the overall supporting effect is guaranteed by supporting the edge of the board or glass, and the placement of objects on the surface of the board or glass will not be affected.

[0035] like Figure 4As shown, the mortise 30 plugged into the plug-in rack 13 is a longitudinal mortise 30, the length direction of the longitudinal mortise 30 is perpendicular to the horizontal plane, the longitudinal mortise 30 is hollow inside, which can reduce the overall mass, and a plug-in rail 31 is fixed on the side wall of the longitudinal mortise 30, and the two ends of the plug-in rail 31 extend to the two ends of the longitudinal mortise 30 respectively. Preferably, the plug-in rail 31 is formed by the side wall of the longitudinal mortise 30 protruding inwardly, and then a protrusion is formed on the inner wall of the longitudinal mortise 30, and a groove is formed on the outer wall, and the groove can be used to embed the outer edge of the partition, etc.; the plug-in rack 13 includes four columns 131, and the four columns 131 are respectively fixed on the outer wall of the connecting block 11 The four corners of the rack 13 are provided with a third connecting hole 132, and a fourth connecting hole 32 is provided on the side wall of the longitudinal mortise 30.

[0036] The outer corner of the connecting block 11 is also provided with a receiving groove 111, which is opened close to the same plug-in rack 13. During the assembly process, the receiving groove 111 is opened close to the plug-in rack 13 at the upper end. The receiving groove 111 is used to support the corner of the external support plate, thereby ensuring the stability of the support of the external support plate and improving the load-bearing capacity.
