[0002] In product packaging, paper box packaging is usually used. Especially today when the demand for express logistics is particularly high, in order to facilitate the packaging of paper boxes, plastic tape is usually used to seal them.

[0003] However, in actual use, the tape will be discarded when it is opened after use, and when the tape is stored for a long time or exposed to sunlight for a long time, it will fail and lose its adhesiveness, and then it will easily break, causing the paper box to be opened. Therefore, a paper box is required that can achieve self-closure and locking structure through structure to prevent it from spreading during storage and transportation. Utility Model Content

[0004] The utility model aims to provide a packaging paper box with a lockable box cover, which solves the problem that the existing paper box needs to be conveniently locked to avoid being accidentally opened.

[0006] One end of the fixed plate used for connection is rotatably connected to one side of the top of the paper box body through a connecting piece, an end of the fixed plate away from the connecting piece is provided with a plug-in piece, and both ends of the plug-in piece are connected to connecting blocks;

[0007] One end of the closing cover for closing is folded and rotatably connected with one end of the top of the paper box body, one end of the closing cover close to the connecting piece is connected with an inserting piece, and both ends of the inserting piece are folded and rotatably connected with folding pieces at one side close to the center of the paper box body;

[0008] Both ends of the penetration strip used for penetration are fixedly connected with support blocks, and the interior of the paper box body is provided with penetration holes corresponding to the penetration strip.

[0009] Preferably, one end of the fixing plate and the connecting piece are folded together to form a curve, and one end of the connecting piece away from the fixing plate is fixed to the top edge of the paper box body.

[0010] Preferably, a support block is provided at one end of the top of the fixing plate close to the plug-in piece, and one end of the support block is in contact with the inner wall of the paper box body, and stop blocks are installed at both ends of the penetration strip.

[0011] Preferably, the penetration strip passes through the interior of the connecting piece and the insertion piece, and a connecting hole corresponding to the penetration strip is opened inside the insertion piece, and a rectangular hole corresponding to the penetration strip is opened inside the connecting piece, and the support blocks at both ends of the penetration strip fit the outer wall of the paper box body.

[0012] Preferably, one side of the support sheet is connected to the top of the paper box body, and the folding sheet on one side of the insertion sheet and the bottom end of the support sheet are in contact with each other for support, and the end of the support sheet away from the insertion sheet is in contact with the top of the support block.

[0014] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0015] The connecting block can be blocked by the card connection frame, thereby fixing the plug-in piece and fixing the position of the fixed plate to prevent it from moving to the top and opening. At the same time, due to the expansion of the connecting blocks on both sides, the plug-in piece can be blocked from being pulled out from the inside of the strip hole. When the through-bar is inserted into the connecting hole, it can be pushed to rotate and unfold to both sides, so that it moves to the bottom of the supporting piece, and then fits with it to block the folding piece from moving to the top, thereby fixing the closing cover. The through-bar can also effectively block the device from opening automatically. At the same time, by installing blocks at both ends of the through-bar, the through-bar is blocked from being pulled out, and the through-bar can always block the fixed plate.
