Description

TECHNICAL FIELD

[0001] The present application relates to the packaging box technical field, in particular to a self-locking type circulating packaging box. BACKGROUND

[0002] The packaging box is the mainstream choice of global freight with its convenience, safety and low cost, etc. The packaging box on the market is composed of a bottom tray, side plates, end plates and a cover plate. The bottom tray is connected with the side plates and the end plates around by nails. After the inner load is loaded, the cover plate is connected with the side plates and the end plates around. The packaging box of this style is more troublesome to assemble, and needs to be assembled first and then transported to the customer site, which occupies the transportation space and increases the transportation cost. At the same time, it is difficult to disassemble after the goods are taken out, the box body is easily damaged, and it cannot be recycled for multiple uses.

[0003] At present, the Chinese invention with the publication number CN104787432A discloses a recyclable quick disassembly type combined packaging box, which comprises at least one male and female groove structure engaged connection between each surrounding plate of the box body. Two bottom supports are arranged at both ends of the box body. The bottom support comprises two limiting plates arranged on both sides of the box body and a support plate connecting the two limiting plates. The connecting buckle is composed of two clamping parts in a bent structure. In the combined state of the box body, the connecting buckle is buckled in the two corresponding preset holes of each male and female groove structure. In the recycling state of the box body, all the surrounding plates are stacked on the bottom tray, and the connecting buckle is buckled on the first preset groove and the surrounding plate stacked on the top layer.

[0004] The existing box body is connected between each surrounding plate by the male and female groove structure. When disassembled, the connecting buckle can be separated from the box body by prying the connecting buckle. The box body is not damaged during assembly and disassembly, and can be repeatedly used with high frequency. However, on the one hand, the existing invention realizes the engagement connection between each surrounding plate of the box body through the male and female groove structure and realizes the fixation through the connecting buckle. During the assembly and disassembly process, the connecting buckle needs to be installed or disassembled, which increases the use cost and also increases the complexity of the box assembly and disassembly. On the other hand, the size of the box body in the existing invention cannot be expanded. In order to adapt to the transportation demand of larger goods, different specifications of surrounding plates need to be produced and manufactured, which increases the manufacturing cost of the box body, and it is necessary to improve.

[0017] 1. Set the side plate based on the first plug-in assembly connected to the two sides of the bottom plate, and the protruding end of the bottom plate is fixed with a limiting abutting block for abutting the two ends of the side plate, and a first supporting abutting block is arranged at the bottom of the side plate for abutting the plug-in block and the bottom surface of the limiting abutting block. When assembling, first insert the side plate into the two sides of the bottom plate, support the bottom of the side plate through the first supporting abutting block, so as to realize that no support is needed after installation, and one person can realize assembly. When the side plate is installed, the short plate is inserted into the bottom plate based on the second plug-in assembly and hung at the two ends of the side plate based on the gravity self-locking assembly. The gravity self-locking assembly is provided with a hanging block at the two ends of the side plate, and a self-locking groove is opened at the top of the hanging block. When installing the end plate, first insert the hanging block into the hanging groove on both sides of the end plate, then put down the end plate so that the end plate is clamped into the self-locking groove, and at the same time, the second plug-in block on the second end plate is inserted into the second plug-in groove of the bottom plate, so that the installation of the end plate is completed. The gravity of the end plate itself enables the end plate to be stably limited by the self-locking groove and the second plug-in groove, thereby ensuring the stability of the end plate and the side plate. Finally, the positioning groove of the cover plate is matched with the side positioning block and the end positioning block to complete the installation of the cover plate. When disassembling, first disassemble the cover plate, then lift the end plate upwards to make the end plate unlock the self-locking groove and pull the end plate outward to complete the disassembly of the end plate. Finally, pull the side plate outward to complete the disassembly. It is convenient to disassemble and assemble;

The end expansion plate of the expansion assembly is hung and connected between the adjacent end plates through the third plug-in assembly and the limiting self-locking assembly. When the size of the box needs to be expanded, first assemble the expansion frame between the adjacent brackets for fixation, then insert the limiting self-locking blocks on both sides of the end expansion plate into the hanging groove of the end plate, and then put down the end expansion plate so that the limiting self-locking groove is clamped and pressed at the bottom of the hanging groove, and the third plug-in block at the bottom of the end expansion plate is inserted into the third plug-in groove of the bottom expansion plate. Finally, install the cover expansion plate to connect the two adjacent packaging boxes, thereby adapting to the transportation demand of larger goods. On the one hand, during the expansion process of the size of the packaging box, the number of parts of the expansion assembly is smaller, and there is no need to manufacture different specifications of plates to adapt to the transportation demand of goods of different specifications, thereby greatly reducing the manufacturing cost of the box and the cost of the production line. On the other hand, the expansion frame is provided with a supporting expansion block, and a fixing groove for accommodating the supporting block is opened on the supporting expansion block. By inserting the supporting block into the fixing groove, the expansion frame and the bracket are firmly combined together.
