[0023] like Figure 1-6 As shown, a packaging box that is easy to assemble and disassemble includes a box body 1, a box cover 2 and a locking mechanism 3. The box cover 2 is buckled on the box body 1, and the locking mechanism 3 is connected to the box cover 2. The locking mechanism 3 includes a limiting plug-in 308, and the limiting plug-in 308 is set to be U-shaped. The limiting plug-in 308 is symmetrically arranged in the box cover 2. The limiting plug-in 308 is sequentially plugged into the box cover 2 and the box body 1, thereby realizing the locking of the box cover 2 and the box body 1.

[0024] like Figure 3 、 4When the cam 312 is in the unlock state, the locking cam 312 is in the unlock state, and the locking cam 312 is in the unlock state, so that the locking cam 312 is locked. One end of the mounting slot 203 is connected to the first mounting slot 202, and the other end of the second mounting slot 203 passes through the mounting plate 201 and is provided with a first socket 205. The box cover 2 is provided with a second socket 206, and the box body 1 is provided with a third socket 101. The other end of the limiting plug-in 308 slides through the first socket 205, the second socket 206 and the third socket 101 in sequence, thereby realizing the locking of the box body 1 and the box cover 2. The upper and lower inner walls of the second mounting slot 203 are symmetrically provided with limiting slots 204, and the upper and lower sides of the limiting plug-in 308 are symmetrically fixed with limiting sliders 310. The limiting sliders 310 are slidably adapted in the limiting slots 204, thereby improving the sliding stability of the limiting plug-in 308. The connecting shaft 302 is fixed with a limiting plate 303, and the box cover 2 is provided with a limiting slot 207. The limiting plate 303 is rotatably adapted in the limiting slot 207, thereby improving the rotation stability of the connecting shaft 302.

[0025] like Figure 5 、 6 As shown, in order to achieve the locking fixation of the connecting shaft 302, a turntable 304 is fixedly connected to the upper end of the connecting shaft 302, and a fastening ring 305 is threadedly connected to the connecting shaft 302. The fastening ring 305 is rotatably arranged between the turntable 304 and the box cover 2. A connecting ring 307 is fixedly connected to the lower end of the fastening ring 305. A connecting groove 208 is provided at the upper end of the box cover 2. The connecting ring 307 is threadedly connected to the connecting groove 208. A plurality of anti-slip ridges 306 are provided on the outer periphery of the fastening ring 305, which facilitates the rotation of the fastening ring 305.

[0026] When the present invention is in use, the rotating disk 304 drives the connecting shaft 302 to rotate, thereby driving the adjusting plate 301 to rotate, so that the two ends of the adjusting plate 301 squeeze the inner wall of the groove 309 of the limiting plug-in 308, thereby driving the limiting plug-in 308 to slide in the second mounting groove 203, and at the same time, the limiting slider 310 slides in the limiting slide groove 204 to improve the sliding stability of the limiting plug-in 308, and the limiting plug-in 308 slides through the first hole 205, the second hole 206 and the third hole 101 in sequence, thereby realizing the limiting plug-in 308 on the box body 1 and the box cover 2 limit, rotate the fastening ring 305 to drive the connecting ring 307 to be threadedly connected to the connecting groove 208 of the box cover 2, and at the same time, the fastening ring 305 is threadedly connected to the connecting shaft 302, thereby fixing the connecting shaft 302, that is, locking the box body 1 and the box cover 2. When unlocking is required, the fastening ring 305 is rotated in the opposite direction to disengage the connecting ring 307 from the connecting groove 208 and then rotated, and then the third socket 101 can push the limiting plug-in 308, so that the limiting plug-in 308 slides out of the third socket 101, thereby unlocking the box body 1 and the box cover 2.

[0027] In summary: In the embodiment of the present invention, the box cover 2 and the box body 1 are connected and locked through the locking mechanism 3, and then the connection between the fastening ring 305 and the box cover 2 is used to lock the connecting shaft 302 in the locking mechanism 3, thereby completing the closure of the box cover 2 and the box body 1. The locking method is simple and can be unlocked by rotating the fastening ring 305 and the turntable 304. It can be repeatedly operated and used, and is highly practical.

[0028] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
