Description

Technical Field

[0001] The utility model relates to the technical field of packaging boxes, and more specifically, to a packaging box which is convenient for assembly and disassembly. Background Art

[0002] Paper packaging boxes are currently a common packaging method for small products. They are usually made by cutting, creasing and folding cardboard. They have a simple structure and low cost. In the process of product sales and promotion, products usually need to be displayed. In order to store the exhibits in a timely manner, they are usually displayed together with the packaging. Frequent opening and closing can easily cause the packaging box to deform or be damaged. In addition, after opening the lid of an ordinary paper packaging box, its lid needs to occupy a large display space, which increases the display cost.

[0003] In view of the above problems, regarding the technical problem that frequent opening and closing may easily cause deformation or damage of the packaging box, after a lot of searches, a packaging box with patent number 202222714492.3 was found, which belongs to the technical field of packaging boxes. A packaging box includes a box body and a box cover cut and folded from a sheet material, and the box body includes a bottom surface, a side surface, a front end surface and a rear end surface; the utility model has a degree of rotational freedom through the provision of a movable plate, and third protrusions are symmetrically provided on the left and right sides of the upper end of the movable plate. The third protrusion is inserted into the notch and can slide in the notch, which meets the needs of product display and packaging. It has high strength and stability, but the technical solution provided by the patent has the following problems:

[0004] During transportation, due to the bumps of the vehicle, the packaging boxes inside the box are more susceptible to external pressure and collisions between the boxes, which can easily lead to deformation and friction damage of the packaging boxes, which is not conducive to subsequent use. At the same time, the packaging boxes will take up more space when transported.

[0005] The utility model can reduce the collision between packaging boxes when transporting packaging boxes, and at the same time reduce the space occupied by the packaging boxes, so that more packaging boxes can be transported. Utility Model Content

[0006] The utility model aims to solve the technical problems raised by the above-mentioned background technology and provide a packaging box which is convenient for assembly and disassembly.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a packaging box that is easy to assemble and disassemble, comprising: a box body, a box cover is movably installed on the upper end of the box body, bending strips are arranged on the sides of the box body, an upper connecting plate and a lower connecting plate are arranged inside the bending strips, and the upper end of the lower connecting plate is embedded in the bottom end of the upper connecting plate.

[0008] A further preferred solution is that a fold groove is provided in the middle of the outer surface of the box body, a limit block is arranged around the upper end of the box body, and insertion holes are provided at the four corners of the upper end of the box body.

[0009] A further preferred solution is that the four corners of the bottom of the box cover are fixedly mounted with plug rods, the plug rods are matched with the sockets provided at the four corners of the upper end of the box body, and the plug rods are embedded in the sockets for connection.

[0010] A further preferred solution is that a movable groove is provided in the middle of the bending strip, and slots are provided at the upper and lower ends of the movable groove, and the slots provided at the upper and lower ends of the movable groove are respectively nested and connected with the upper connecting plate and the lower connecting plate.

[0011] A further preferred solution: a rotating shaft is provided at the bottom of the upper connecting plate, a limiting plate is fixedly installed on the front of the rotating shaft, limiting grooves are provided on the left and right sides of the front of the limiting plate, and the output shaft of the rotating shaft passes through the left and right ends of the bottom of the upper connecting plate and is embedded in the lower connecting plate for connection.

[0012] A further preferred solution is that both left and right sides of the front surface of the lower connecting plate are provided with clamping blocks, and the clamping blocks are matched with the limiting grooves.

[0013] Beneficial effects:

[0014] 1. By setting a limit block, a plug rod and a socket, the limit block is used to initially limit the inside of the box cover, and the limit block clamps the inside of the box cover to prevent the box cover from sliding on the box body. At the same time, the plug rod is inserted into the inside of the socket to further limit and fix the box cover. The plug rod is fixed by the socket, so that the box cover can be better covered on the top of the box body, and the top of the box body is restricted to prevent the items inside the box body from being thrown out of the box body due to bumps and other reasons;

[0015] 2. By providing the bending strips and crease grooves, when the box body is folded, the connection between the rotating shaft and the upper connecting plate and the lower connecting plate is used to push the rotating shaft to move inside the box body, so that the block is withdrawn from the limiting groove, and the limiting plate on the lower connecting plate is released. The upper connecting plate and the lower connecting plate are contracted to the inside of the box body through the rotating shaft to form a V shape, and the box body is folded inward on all sides with the crease grooves. The box body eventually changes from a box shape to a folded shape, and from a box body to a single plate shape, which reduces the space occupied when transporting packaging boxes, so that more packaging boxes can be transported;

[0016] 3. In summary, this kind of packaging box which is easy to assemble and disassemble is provided with structures such as an upper connecting block, a lower connecting block and a rotating shaft. By pushing the rotating shaft inward, the upper connecting plate and the lower connecting plate are changed from a vertical state to a horizontal state. When the rotating shaft is pulled outward, the upper connecting plate is pulled upward obliquely, and the lower connecting plate is driven to move outward by the rotating shaft, so that the upper connecting plate and the lower connecting plate are changed from a side V-shape to a vertical state. When the upper connecting plate and the lower connecting plate are changed from a vertical state to a horizontal state, the box body gradually changes from a box shape to a side V-shape, forming a foldable type, thereby reducing space occupancy. When the upper connecting plate and the lower connecting plate are changed from a side V-shape to a vertical state, they change from a folded shape to a box shape again, so that items can be put into it.

[0022] The following will be combined with the attached embodiment of the present utility model Figure 1-Figure 4 , clearly and completely describe the technical solutions in the embodiments of the utility model.

[0023] See also Figure 1-4, In the embodiment of the utility model, a packaging box with convenient disassembly and assembly comprises: a box body 1, a box cover 2 is movably installed on the upper end of the box body 1, a bending strip 3 is arranged on the side of the box body 1, an upper connecting plate 4 and a lower connecting plate 5 are arranged inside the bending strip 3, and the upper end of the lower connecting plate 5 is embedded in the bottom end of the upper connecting plate 4, a folding groove 101 is opened in the middle of the outer surface of the box body 1, a limiting block 102 is arranged around the upper end of the box body 1, and a plug hole 103 is opened at the four corners of the upper end of the box body 1, and an insertion rod 201 is fixedly installed at the four corners of the bottom of the box cover 2, and the insertion rod 201 is matched with the plug holes 103 opened at the four corners of the upper end of the box body 1, and the insertion rod 201 is embedded in the internal connection of the plug hole 103. When installing and making the packaging box, a placement cavity is opened inside the box body 1, and items can be placed in the placement cavity. Then a folding groove 101 is opened on the outer surface of the box body 1, which is convenient for the box body 1 to be folded and reduce the placement space. The box cover 2 is provided with a circle of limit blocks 102 around the upper end of the box body 1, and the limit blocks 102 are matched with the grooves inside the box cover 2, so that the box cover 2 is restricted by the limit blocks 102 and will not move easily above the box body 1. The insertion rod 201 at the bottom of the box cover 2 cooperates with the insertion hole 103 at the upper end of the box body 1, and the insertion rod 201 is inserted into the insertion hole 103, so as to further limit the box cover 2, so that the connection between the box body 1 and the box cover 2 is more stable and firm, and the box cover 2 is not easy to slide off from above the box body 1 during transportation. The bending strips 3 provided on the outer side surface of the box body 1 are matched with the crease grooves 101 on the surface of the box body 1. When the bending strips 3 shrink inwardly, the box body 1 can be folded inwardly through the crease grooves 101, so as to reduce the space occupied when placed. When opened, the upper connecting plate 4 and the lower connecting plate 5 are connected and limited, so that the box body 1 will not rebound inward and return to the folded shape when it changes from a folded shape to a box shape, so that the box body 1 is more stable when it is three-dimensional.

[0024] In the embodiment of the utility model, a movable groove 301 is opened in the middle of the bending strip 3, and slots 302 are opened at the upper and lower ends of the movable groove 301. The slots 302 opened at the upper and lower ends of the movable groove 301 are respectively nested and connected with the upper connecting plate 4 and the lower connecting plate 5. A movable groove 301 is opened in the middle of the bending strip 3. The movable groove 301 can ensure that the bending joints of the upper connecting plate 4 and the lower connecting plate 5 are not affected by the bending strip 3 during the bending process, making the bending movement more convenient.

[0025] In the embodiment of the utility model, a rotating shaft 401 is provided at the bottom of the upper connecting plate 4, and a limiting plate 402 is fixedly installed on the front of the rotating shaft 401. Limiting grooves 403 are provided on the left and right sides of the front of the limiting plate 402. The output shaft of the rotating shaft 401 passes through the left and right ends of the bottom of the upper connecting plate 4 and is embedded in the lower connecting plate 5 for internal connection. Blocks 501 are provided on the left and right sides of the front of the lower connecting plate 5. The block 501 is matched with the limiting groove 403. When the box body 1 is folded, the rotating shaft 401 is pushed toward the inside of the box body 1 through the connection between the rotating shaft 401 and the upper connecting plate 4 and the lower connecting plate 5, so that the block 501 is pushed out from the limiting groove 403 to release the box body 1. The limiting plate 402 limits the fixed position of the lower connecting plate 5, and the upper connecting plate 4 and the lower connecting plate 5 shrink toward the inside of the box body 1 through the rotating shaft 401 to form a V-shape, and the crease groove 101 is used to make the box body 1 fold inward on all sides, and the box body 1 eventually changes from a box shape to a folded shape, which reduces the occupied space when transporting and storing the packaging boxes. When the folded shape changes to a box shape, the upper end of the box body 1 is pulled upward to make the upper connecting plate 4 pulled outward through the rotating shaft 401, and the upper connecting plate 4 drives the lower connecting plate 5 from a horizontal state to a vertical state. When it is completely vertical, the block 501 is inserted into the limiting groove 403 to keep the upper connecting plate 4 and the lower connecting plate 5 vertical, so that the box body 1 changes from a folded shape to a box shape.

[0026] Working principle: By pushing the rotating shaft 401 inward, the upper connecting plate 4 and the lower connecting plate 5 can be changed from a vertical state to a horizontal state, the block 501 is withdrawn from the limiting groove 403, and the rotating shaft 401 is pushed toward the inside of the box body 1. The rotating shaft 401 cooperates with the crease groove 101 to shrink the box body 1 inward. The upper connecting plate 4 and the lower connecting plate 5 are in a side V shape at this time, and the box body 1 becomes a folded state. When the rotating shaft 401 is pulled outward, the upper connecting plate 4 is pulled upward obliquely, and the lower connecting plate 5 is driven to move outward through the rotating shaft 401, so that the upper connecting plate 4 and the lower connecting plate 5 are changed from a side V shape to a vertical state, and the box body 1 changes from a folded state to a box shape, and items can be put into the box body 1 later.
