[0024] This part will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the drawings. The function of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it cannot be understood as a limitation on the protection scope of the present utility model.
[0025] Referring to Figure 1-7 , an environmentally friendly self-locking corrugated paper packaging box according to an embodiment of the present utility model includes a box body, and two first folding edges are symmetrically arranged at the top of the box body. Locking components are arranged on both sides of the two first folding edges facing each other;
[0026] The locking assembly includes two second flanges formed on corresponding first flanges, two clamping plates formed on the side of the corresponding second flanges close to the box body, two card slots opened inside the box body and matingly inserted with the corresponding clamping plates, two third flanges formed on the side where the corresponding second flanges are close to each other, and two slots opened inside the corresponding second flanges and on the side opposite to the clamping plates. Both of the two third flanges are L-shaped structures with fourth flanges, and both of the two fourth flanges are matingly inserted with the corresponding slots.
[0027] After the first flange is bent and covers the top of the box body, the second flange is flipped to drive the clamping plate to connect with the card slot, so that the locking operation between the first flange and the box body can be realized. The third flange and the fourth flange are rotated, and the fourth flange is inserted into the slot, so that the locking operation of the two first flanges can be realized, and then the self-locking operation of the packing box can be realized. The structure is stable, easy to assemble and disassemble, and the locking assembly and the box body are of an integral structure, avoiding the problems of insufficient environmental protection and inconvenient recycling caused by the need to add additional components, and having strong practicability.
[0028] In order to facilitate the user to operate the fourth flange, an operation part is opened on one side of each of the four second flanges close to the slot. The operation part can be a small hole or a groove, through which the user can easily insert or pull out the fourth flange of the third flange with a finger.
[0029] In order to enhance the load-bearing capacity of the top of the box body, two reinforcing rib plates are symmetrically arranged at the bottom of the two first flanges, and the bottoms of the reinforcing rib plates are both of an inclined surface structure, which helps to disperse the top pressure and increase the overall strength.
[0030] An extension part is formed on one side of one first flange close to the other first flange. The extension part covers the connection part of the two first flanges, and the extension part can enhance the sealing performance of the top of the box body.
[0031] Two handle parts are symmetrically opened inside the outer surface of the box body, and the handle parts are perpendicular to the second flanges, which is convenient for the user to grasp and lift the packing box during handling and transportation.
[0032] Working principle: After the first flange is bent and covers the top of the box body, the second flange is flipped to drive the clamping plate to connect with the card slot, so that the locking operation between the first flange and the box body can be realized. The third flange and the fourth flange are rotated, and the fourth flange is inserted into the slot, so that the locking operation of the two first flanges can be realized, and then the self-locking operation of the packing box can be realized. The structure is stable, easy to assemble and disassemble, and the locking assembly and the box body are of an integral structure, avoiding the problems of insufficient environmental protection and inconvenient recycling caused by the need to add additional components, and having strong practicability.
