Description

Technical Field

[0001] The utility model relates to the technical field of packaging box lock buckles, in particular to a packaging box plastic lock buckle, which has low cost and is easy to install. Background Art

[0002] At present, the structure of plywood boxes generally consists of a base, four facades and a top cover. The locking between the facades, the top cover and the base is done by iron locks. The locks of plywood boxes are required to be strong and durable, easy to lock and can be disassembled three to four times without breaking, so as to ensure that the packaging box is not damaged during transportation and is easy to disassemble after being sent to the customer.

[0003] Problems with existing iron locks: 1. Iron locks require stamping dies to be made; installing iron locks on plywood requires a corresponding press. 2. Iron locks need to be hit with a hammer to be locked, which is labor-intensive for employees and noisy in the workshop. 3. Iron locks also require corresponding tools to be disassembled, and are easily deformed after repeated use. 4. Iron lock boxes are extremely easy to scratch employees during production, transportation and storage, which poses a great safety hazard. Summary of the invention

[0004] The purpose of the utility model is to change the material and structure of the lock buckle, from the original iron lock buckle to a plastic lock buckle, which changes the locking method in structure, reduces the difficulty of making packaging boxes, and also reduces the labor intensity and the probability of injury of employees, improves the production efficiency of packing and unpacking, and makes the packaging boxes reusable.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a packaging box lock, including an expansion bolt, a buckle, and a hook. The buckle is inserted into a round hole of the packaging box, one end of the buckle is connected to a sheet-shaped hook with a bend, and the other end of the buckle is connected to the expansion bolt. The expansion bolt can be bent and inserted into the inner hole of the buckle, and the hook is installed in the iron corner groove of the upper cover of the packaging box.

[0006] Further preferably, the lock is made of plastic.

[0007] Further preferably, the buckle includes three groups of V-shaped openings.

[0008] Compared with the prior art, the utility model has the following beneficial effects: the plastic lock buckle is easy to make and has low cost. The tools used by employees to install and remove the plastic lock buckle are relatively simple: installation can be completed with bare hands, and removal can be completed with only a screwdriver, which reduces the labor intensity of employees. The packaging box replaced with the plastic lock buckle does not damage the structure of the original box when unpacking, making it easier to reuse the packaging box, saving packaging costs.

[0016] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. The components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0017] like Figure 1 to Figure 2 As shown, the original iron lock sealing order:

[0018] (1) Place the four outer surfaces of the packaging box 1 on the bottom bracket and use a hammer to hit the iron lock buckle upwards to lock it.

[0019] (2) Install the upper cover of the packaging box 1 on the four outer facades.

[0020] (3) Use a hammer to hit the iron lock buckle downward to lock the upper cover.

[0021] The iron lock buckle needs to be made into a stamping die, and the installation of the iron lock buckle requires a corresponding press. The iron lock buckle needs to be hit with a hammer when it is locked, which is labor-intensive for employees and noisy in the workshop. The iron lock buckle also needs corresponding tools to be disassembled, and it is easy to deform after repeated use. The iron lock buckle box is extremely easy to scratch employees during the production, transportation and storage process, which poses a great safety hazard.

[0022] Based on the problems with the original lock, we first need to solve the material problem and change the iron lock into a plastic product. Secondly, without changing the structure of the original packaging box, replace the iron locks on the four exterior surfaces of the packaging box with round holes, and use the buckles and expansion bolts on the lock to lock the upper cover and bottom support.

[0023] The specific structure of a packaging box lock buckle of the utility model is as follows: it includes an expansion bolt 3, a buckle 4, and a hook 5. The buckle 4 is inserted into the round hole of the packaging box 1. One end of the buckle 4 is connected to the sheet-shaped hook 5 with a bend. The other end of the buckle 4 is connected to the expansion bolt 3. The expansion bolt 3 can be bent and inserted into the inner hole of the buckle 4. The hook 5 is installed in the iron corner groove of the upper cover of the packaging box. The lock buckle is made of plastic. The buckle 4 includes 3 groups of V-shaped openings. The V-shaped openings are easy to shrink and expand under the action of external force. Under the action of external force, the buckle 4 is easy to be inserted into the round hole of the plywood when it shrinks; under the action of external force, the buckle 4 is easy to expand after the expansion bolt 3 is inserted.

[0024] The improved plastic lock shape and the sealing and unpacking sequence of the utility model are described. Figures 3 to 6 .

[0025] The sealing sequence of this utility model:

[0026] (1) Install the four outer surfaces of the packaging box 1 on the base.

[0027] (2) Install the upper cover of the packaging box 1 on the four outer facades.

[0028] (3) Hang the hook 5 of the lock in the iron corner groove of the upper cover of the packaging box 1.

[0029] (4) Press the buckle 4 of the lock into the circular hole on the outer surface of the packaging box 1.

[0030] (5) Press the expansion bolt 3 of the lock into the inner hole of the buckle 4, so that the buckle 4 expands and tightens in the round hole of the box.

[0031] (6) Finally, follow the above steps to lock the four facades and the base.

[0032] The unpacking sequence of the present invention is opposite to the sealing sequence.

[0033] This plastic lock is small in size, easy to form, and can be sealed and unpacked flexibly and quickly. At the same time, the box boards are stored more neatly, without the protruding sharp corners of the iron lock, which does not affect the work safety of employees, reduces safety hazards, and greatly reduces the noise on the packaging site. This lock structure has been extended to other similar plywood boxes and has also achieved ideal results, proving the rationality of the structure.

[0034] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
