Description

Technical Field

[0001] This utility model belongs to the field of packaging paper boxes, and specifically relates to environmentally friendly packaging paper boxes that are easy to seal. Background Technology

[0002] Chinese Patent No. CN211281834U discloses a convenient packaging box, including a carton body. Long sealing plates are fixed to two opposite sides of the top surface of the carton body, and a short sealing plate is fixed to the side of the top surface of the carton body closest to the long sealing plates. The long and short sealing plates are made of the same material as the carton body. The connection point between the long sealing plate and the carton body is higher than the connection point between the short sealing plate and the carton body, and the height difference is consistent with the thickness of the short sealing plate, which is between 0.2 and 0.6 mm thick. Multiple fixing grooves are equidistantly provided on the side of the long sealing plate away from the carton body, and two long sealing plates are engaged through these fixing grooves. The fixing grooves are straight teeth. The combined use of these devices improves the efficiency of carton packaging and reduces the use of adhesive tape, thus avoiding the harm to workers' health caused by the highly toxic substances in adhesive tape.

[0003] As can be seen from the above structure, by pulling the connecting rod, the connecting rod drives the fixed rod to slide inside the movable hole and insert between the movable hole and the insertion hole, which can realize the fixation between the two long sealing plates. This can avoid the use of tape during packaging. However, the packaging structure of the carton body is integrated with the carton body. Since the carton body itself is made of a fragile material, the packaging structure cannot be reused when the carton body is damaged, which increases the cost of the carton body. Utility Model Content

[0004] In view of the problems mentioned in the background art, the purpose of this utility model is to provide an environmentally friendly packaging cardboard box that is easy to seal, so as to solve the problems mentioned in the background art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] An environmentally friendly packaging box for easy sealing includes a box body and a connecting assembly. Width covers are fixedly connected to the upper left and right sides of the box body, and length covers are fixedly connected to the upper front and rear sides of the box body. The other side of each length cover is fixedly connected to the connecting assembly. A connecting plate is fixedly connected to the other end of each connecting assembly, and a sealing assembly is fixedly connected to the other end of each connecting plate. The connecting assembly includes a connecting frame, which is interlocked with the length covers. A reset spring is fixedly connected to the upper end of the connecting frame, and a reset plate is fixedly connected to the other end of the reset spring. A fixing cone is fixedly connected to the inner side of the reset plate. A connecting through hole is provided on the surface of the connecting frame, and the fixing cone penetrates the length covers and interlocks with the connecting through hole.

[0007] As a preferred technical solution, the packaging component includes a snap-fit ​​block, and a snap-fit ​​frame is fixedly connected to the other side of the connecting plate on the other side of the upper end of the paper box body, and the snap-fit ​​block and the snap-fit ​​frame are interlocked.

[0008] As a preferred technical solution, square grooves are provided on both sides of the snap-fit ​​block, and snap-fit ​​springs are fixedly connected inside the square grooves. A snap-fit ​​connector is fixedly connected to the other end of the snap-fit ​​springs. A snap-fit ​​hole is provided on the inner side of the snap-fit ​​frame, and the snap-fit ​​hole and the snap-fit ​​connector snap together.

[0009] As a preferred technical solution, a sliding hole is provided at the upper end of the square groove, a connecting rod is fixedly connected to the upper end of the snap connector, and an operating handle is fixedly connected to the other end of the connecting rod. The connecting rod and the sliding hole are slidably connected to each other.

[0010] As a preferred technical solution, the upper end of the snap-fit ​​block and the lower end of the connecting rod are slidably connected to each other, and a limiting groove is provided on both sides of the upper end of the snap-fit ​​block. A limiting slider is fixedly connected to the lower end of the connecting rod, and the limiting slider and the limiting groove are slidably connected to each other.

[0011] As a preferred technical solution, a bottom protective seat is provided at the lower end of the paper box body. The bottom protective seat is located at the lower corner of the paper box body and is inserted into the lower end of the paper box body.

[0012] As a preferred technical solution, the paper box body has movable slots on both sides, and a reinforced protective shell is fixedly connected inside the movable slot. The outer side of the reinforced protective shell is bonded to the inner side of the movable slot.

[0013] In summary, the present invention has the following main advantages:

[0014] First, during connection, the connecting frame and the length cover plate are interlocked. The fixing cone on the inner side of the connecting plate passes through the length cover plate and is interlocked with the connecting through hole on the surface of the connecting frame, thereby achieving sealing and fixing. When the carton body is damaged and it is necessary to disassemble the connecting component from the carton body, the connecting plate is pulled, the reset spring is stretched, and the fixing cone is disengaged from the connecting through hole, which makes it easy to disassemble the connecting component from the carton body. This allows for flexible disassembly during use, reducing production and replacement costs.

[0015] Secondly, this utility model, through its encapsulation component, allows the snap-fit ​​block to be inserted into the snap-fit ​​frame during encapsulation. The snap-fit ​​springs in the square slots on both sides of the snap-fit ​​block push the snap-fit ​​connector out, causing it to snap into the snap-fit ​​hole on the inner side of the snap-fit ​​frame, thus securing the cardboard box tightly. When opening is required, the connecting rod is moved along the sliding hole by sliding the operating handle. The connecting rod pulls the snap-fit ​​connector to compress the snap-fit ​​spring, causing the snap-fit ​​connector to disengage from the snap-fit ​​hole. This allows the snap-fit ​​block to be pulled out of the snap-fit ​​frame, releasing the snap-fit ​​state. Through the insertion and engagement of the snap-fit ​​block and the snap-fit ​​frame, combined with the snap-fit ​​action of the snap-fit ​​connector and the snap-fit ​​hole, the cardboard box encapsulation becomes more secure and reliable, effectively preventing accidental opening of the cardboard box during transportation or storage.

[0027] Operating principle and advantages: During use, the sealing component 6 is connected to the carton body 1. During connection, the connecting frame 41 and the length cover plate 3 are interlocked. The fixing cone 44 on the inner side of the connecting plate 5 penetrates the length cover plate 3 and interlocks with the connecting through hole 45 on the surface of the connecting frame 41, thereby achieving sealing and fixation. Then, during sealing, the snap-fit ​​block 61 is inserted into the snap-fit ​​frame 62. The snap-fit ​​springs 65 in the square slots 64 on both sides of the snap-fit ​​block 61 will push the snap-fit ​​connector 66 out, so that it interlocks with the snap-fit ​​hole 63 on the inner side of the snap-fit ​​frame 62, thereby completing the tight fixation of the carton. When it is necessary to open, the connecting rod 68 is moved along the sliding hole 67 by the sliding operation handle 69. The connecting rod 68 pulls the snap-fit ​​connector 66 to compress the snap-fit ​​spring 65, so that the snap-fit ​​connector 66 is disengaged from the snap-fit ​​hole 63, and the snap-fit ​​block 61 can be pulled out from the snap-fit ​​frame 62. When the cardboard box body 1 is damaged, the connecting component 4 needs to be disassembled from the cardboard box body 1. Pulling the connecting plate 5 will stretch the reset spring 42 and the fixing cone 44 will disengage from the connecting through hole 45, thus making it easier to disassemble the connecting component 4 from the cardboard box body 1. This allows for flexible disassembly and reduces production and replacement costs. A bottom protective seat 7 is inserted at the lower corner of the cardboard box body 1 to support and protect the bottom corner. At the same time, a reinforcing protective shell 9 is glued inside the moving grooves 8 on both sides of the cardboard box body 1 to enhance the structural strength of both sides of the cardboard box body 1.
