[0018] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] See Figures 1-3 A mortise and tenon joint structure includes two plugs 100 and one pin 200, wherein: The plug 100 has a first end, which has a tenon 110, a slot 120, and a mortise 130. The slot 120 is located between the tenon 110 and the mortise 130. In a direction perpendicular to the first end, the mortise 130 is recessed relative to the slot 120, and the tenon 110 protrudes relative to the slot 120, that is, the mortise 130, the slot 120, and the tenon 110 are arranged in a stepped manner. The end of the mortise 130 near the slot 120 extends to the bottom of the slot 120 and covers a portion of the slot 120, so that the mortise 130 communicates with the slot 120. The tenon 110 is arranged parallel to the first end, and the end of the tenon 110 near the slot 120 extends to the top of the slot 120 and covers a portion of the width of the slot 120, that is, the mortise 130 and the tenon 110 extend to opposite positions of the slot 120.

[0020] When two plugs 100 are inserted into each other, the tenon 110 of one plug 100 is inserted into the mortise 130 of the other plug 100, and the tenon 110 of the other plug 100 is inserted into the mortise 130 of one plug 100. At this time, the tenons 110 of the two plugs 100 are located above and below the slot 120, respectively, and the pin 200 is inserted into the slot 120 of the two plugs 100. Then, the two tenons 110 hook the upper and lower surfaces of the pin 200, respectively, thus achieving the effect of the two plugs 100 not separating, realizing the mortise and tenon connection between the two plugs 100.

[0021] Additionally, when the two plugs 100 are inserted into each other, the tenon 110 fits perfectly into the mortise 130.

[0022] In this embodiment, the end of the mortise 130 near the slot 120 extends below the slot 120 and covers half of the slot 120, and the end of the tenon 110 near the slot 120 extends above the slot 120 and covers the other half of the width of the slot 120; when the two plugs 100 are inserted into each other and the pin 200 is inserted into the slot 120 of the two plugs 100, one tenon 110 just hooks half of the width of the pin 200, and the other tenon 110 just hooks the other half of the width of the pin 200.

[0023] In this embodiment, two protrusions 140 are provided at the two corners of the first end, and the two protrusions 140 are located on both sides of the tenon 130; two grooves 150 are provided at the other two corners of the first end, and the two grooves 150 are located on both sides of the tenon 110; the two protrusions 140 of one plug 100 are respectively inserted into the two grooves 150 of another plug 100, and the two protrusions 140 of the other plug 100 are respectively inserted into the two grooves 150 of one plug 100. The mutual cooperation of the two protrusions 140 and the two grooves 150 makes the connection between the two plugs 100 more suitable and complete.

[0024] In this embodiment, the plug 100 has a second end, which is adjacent to the first end. The second end has a boss 160, and the slot 120 extends to and passes through the boss 160. That is, the pin 200 can be inserted into the slot 120 from the boss 160. The bosses 160 of the two plugs 100 serve to press the pin 200.

[0025] In this embodiment, the pin 200 is provided with a limiting block 210, and the boss 160 is provided with a limiting groove 161; in a direction perpendicular to the first end, the limiting groove 161 is recessed relative to the slot 120; when the pin 200 is inserted into the slot 120, the limiting block 210 is located in the limiting groove 161, and the limiting block 210 plays the role of controlling the insertion degree of the pin 200.

[0026] In this embodiment, there are two limiting blocks 210, and the two limiting blocks 210 are positioned opposite each other; there are also two limiting grooves 161, and the two limiting grooves 161 are positioned opposite each other, which better controls the insertion degree of the pin 200.

[0027] In this embodiment, the plug 100 has a third end, and the third end has a connecting strip 170. The connecting strips 170 of the two plugs 100 are used to connect an external structure. Specifically, an external structure is disposed between the two connecting strips 170, and the external structure can be fixedly or movably disposed between the two connecting strips 170. There are various ways in which the connecting strip 170 connects to the external structure. For example, the connecting strip 170 has a connecting hole 171, and the external structure has a connecting shaft adapted to the connecting hole 171. The connecting hole 171 is used for the connecting shaft of the external structure to be inserted. Depending on the size of the connecting hole 171 and the connecting shaft, the external structure can be configured to be fixed between the two connecting strips 170 or rotatably disposed between the two connecting strips 170.

[0028] The above description is merely a specific embodiment of the present invention, enabling those skilled in the art to understand or implement the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features claimed herein.
