[0047] The following is a preferred embodiment of a buckle with a mortise and tenon structure provided by the present invention that can solve the above technical problems.

[0048] A preferred embodiment of a mortise and tenon structure buckle provided by the present invention is: a mortise and tenon structure buckle, which includes a first rivet 11 and a second rivet 12 arranged opposite to each other; the first rivet 11 includes a first base 111 and a first plug 112, and a first slot 1111 is provided at one end of the first base 111; the first plug 112 is provided at one end of the first base 111, and the first plug 112 is located on one side of the first slot 1111.

[0049] The second rivet 12 is arranged opposite to the first rivet 11. The second rivet 12 has the same structure as the first rivet 11. The second rivet 12 includes a second base 121 and a second plug 122. A second slot 1211 is provided at the other end of the second base 121, and the second slot 1211 is riveted to the first plug 112; the second plug 122 is provided at the other end of the second base 121, and the second plug 122 is located on one side of the second slot 1211, and the second plug 122 is riveted to the first slot 1111.

[0050] A buckle with a mortise and tenon structure forms a stable connection through the interlocking of a first rivet 11 and a second rivet 12. The riveted connection between the first plug 112 and the second slot 1211, and the second plug 122 and the first slot 1111, ensures a tight fit and resists loosening or falling off, thus enhancing the overall structural stability. The mortise and tenon design eliminates the need for additional connectors or tools during assembly; simply insert the first plug 112 into the second slot 1211, and the second plug 122 into the first slot 1111.

[0051] The structure of the first rivet 11 in this embodiment is described in detail as follows:

[0052] Combine Figure 1 、 Figure 2 and Figure 4In this embodiment, the first plug 112 includes a first fixing portion 1121, a first plugging portion 1123 and a first reinforcing portion 1122; the first fixing portion 1121 is located at one end of the first plug 112, and the first fixing portion 1121 is connected to the first base 111, and the first fixing portion 1121 is provided with a first limiting surface 11211 on the side close to the first slot 1111, and the first limiting surface 11211 limits the position of the second rivet 12, thereby increasing the accuracy and stability of assembly; the first plugging portion 1123 is located at the other end of the first plug 112, and the first plugging portion 1123 is riveted to the second slot 1211; the first reinforcing portion 1122 is located in the middle of the first plug 112, and the first reinforcing portion 1122 is connected to one end of the first base 111 near the side of the first fixing portion 1121, and the first reinforcing portion 1122 extends downward.

[0053] Combine Figure 3 Furthermore, the first plug-in portion 1123 has a first curved surface 11231 at its top and a second curved surface 11232 at its bottom. Both the first curved surface 11231 and the second curved surface 11232 face downward. The structure of the second slot 1211 matches that of the first plug-in portion 1123. The curved surface disperses the impact force during assembly, reducing wear on the plug-in portion and the slot. This curved surface design makes it easier for the plug-in portion to enter the slot during riveting, reducing assembly difficulty.

[0054] In this embodiment, the first base 111 is provided with a first positioning groove 1112, and the second rivet 12 further includes a first positioning block 123, which engages with the first positioning groove 1112. The engagement between the positioning groove and the positioning block ensures the accurate positioning of the rivet on the base, improving assembly accuracy and helping to prevent the two rivets from loosening during long-term use.

[0055] Furthermore, the first positioning groove 1112 is located above the first plug 112, and a first groove 11212 is provided at the top of the first plug 112; the second rivet 12 also includes a first protrusion 124, which is engaged with the first groove 11212, further enhancing the connection strength between the plug and the rivet.

[0056] In this embodiment, a first connecting surface 11221 is provided on the side of the first reinforcement portion 1122 away from the first base 111, with the distance between the first connecting surface 11221 and the first base 111 gradually decreasing from top to bottom. A second connecting surface 1213 is provided on the side of the second base 121 closer to the first base 111, and the second connecting surface 1213 matches the first connecting surface 11221. When the two riveted parts are fully assembled, the inclined first connecting surface 11221 and the second connecting surface 1213 will abut against each other, forming a locking effect that helps prevent the lock from loosening or separating when subjected to external forces, thereby improving the stability and reliability of the connection.

[0057] The structure of the second rivet 12 in this embodiment is described in detail as follows:

[0058] Combine Figure 1 、 Figure 2 and Figure 3 The second rivet 12 has the same structure as the first rivet 11. The second plug 122 includes a second fixing portion (not shown), a second plug-in portion 1223, and a second reinforcement portion (not shown). The second fixing portion is located at one end of the second plug 122 and is connected to the second base 121. A second limiting surface is provided on the side of the second fixing portion near the second slot 1211, which defines the position of the first rivet 11. The second plug-in portion 1223 is located at the other end of the second plug 122 and is riveted to the first slot 1111. The second reinforcement portion is located in the middle of the second plug 122 and is connected to one end of the second base 121 near the second fixing portion. The second reinforcement portion extends downward. The second plug 122 includes a second fixing portion, a second plug-in portion 1223, and a second reinforcement portion. Its structure is similar to that of the first plug 112, but its position is opposite. Due to the symmetry of the structure, the first plug 112 and the second plug 122 can be used interchangeably, increasing the flexibility of use.

[0059] Furthermore, a third curved surface 12231 is provided at the top end of the second plug-in portion 1223, and a fourth curved surface 12232 is provided at the bottom end of the second plug-in portion 1223, and the openings of the third curved surface 12231 and the fourth curved surface 12232 are both downward; the structure of the first slot 1111 matches the second plug-in portion 1223; similar to the first plug-in portion 1123, this design helps to simplify the assembly process and reduce wear.

[0060] In this embodiment, a second positioning groove 1212 is provided on the second base 121 , and the first rivet 11 further includes a second positioning block 113 . The second positioning block 113 engages with the second positioning groove 1212 to ensure accurate positioning of the rivet and prevent loosening.

[0061] Furthermore, the second positioning groove 1212 is located above the second plug 122, and a second groove (not shown in the figure) is provided at the top of the second plug 122; the first rivet 11 also includes a second protrusion 114, and the second protrusion 114 is located at the bottom end of the second positioning block 113. The second protrusion 114 is engaged with the second groove, which is the same as the groove and protrusion at the top of the first plug 112. This design enhances the connection strength.

[0062] In this embodiment, a third connecting surface 12221 is provided on the side of the second reinforcement portion away from the second base 121, and the cross-sectional width of the second reinforcement portion gradually decreases downward; a fourth connecting surface 1113 is provided on the side of the first base 111 close to the second base 121, and the fourth connecting surface 1113 matches the third connecting surface 12221, ensuring a tight connection between the plug and the base.

[0063] The working principle of this utility model:

[0064] 1. Align the first plug 112 of the first rivet 11 with the second slot 1211 of the second rivet 12 , and ensure that the first positioning block 123 corresponds to the first positioning groove 1112 .

[0065] Align the second plug 122 of the second rivet member 12 with the first slot 1111 of the first rivet member 11 , and ensure that the second positioning block 113 corresponds to the second positioning groove 1212 .

[0066] Second, fully insert the first plug-in portion 1123 into the second slot 1211, and at the same time, fully insert the second plug-in portion 1223 into the first slot 1111. The curved surface design on the first plug-in portion 1123 and the second plug-in portion 1223 helps reduce impact and wear during assembly, making the riveting process smoother.

[0067] 3. When the first and second rivet members 11 and 12 are fully assembled, the first connection surface 11221 of the first reinforcement 1122 abuts against the second connection surface 1213 of the second base 121, creating a locking effect. Simultaneously, the groove at the top of the first plug 112 engages with the first protrusion 124 of the second rivet member 12, and the groove at the top of the second plug 122 engages with the second protrusion 114 of the first rivet member 11, further enhancing the stability and reliability of the connection.

[0068] This completes the use of the buckle with a mortise and tenon structure of the preferred embodiment.

[0069] This new buckle, which originally required multiple components, now uses a single component to achieve the buckle's function. The components are connected together through a snap-fit ​​method. This product can be assembled from a single component, so only one mold is needed during the mold-making phase. This reduces production efficiency, reduces the number of components, and eliminates the need for manual assembly, significantly reducing production time.

[0070] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. A person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined by the claims.
