Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, and in particular to a pressure-resistant packaging box structure. Background Technology

[0002] like Figure 4 As shown, this is the previous generation of ring-wrapped packaging box structure. Its main function is to package and transport valuables to prevent them from being damaged during transportation. Compared with the conventional single-layer corrugated cardboard packaging box structure, it has better pressure resistance, impact resistance and deformation resistance due to the use of double-layer ring-wrapped thickened cardboard structure.

[0003] With the increasing demands for safety and protection in the packaging and transportation of valuables, the previous generation of wrap-around packaging box structure can no longer meet the current packaging and transportation requirements. When a large force is applied to the top or side of the packaging box, the entire packaging box is prone to dents, deformation, folding and tearing. The pressure resistance of the packaging box needs to be improved.

[0004] In view of this, it is particularly important to design and manufacture a compression-resistant packaging box structure that can comprehensively improve the horizontal and vertical compression resistance of the packaging box, and apply it in the actual design, manufacturing and use of the packaging box. Utility Model Content

[0005] The purpose of this utility model is to propose a pressure-resistant packaging box structure to address the problem that the traditional ring-shaped packaging box structure needs to improve its resistance to pressure, impact, and deformation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A pressure-resistant packaging box structure includes a lower packaging base, an upper screw cap integrally fixed to the upper end of the lower packaging base, and a box body bonded and fixed between the lower packaging base and the upper screw cap. Reinforcing parts for improving the lateral and longitudinal pressure resistance of the packaging box are provided between the four corners of the lower packaging base, the upper screw cap and the box body.

[0007] As a further description of the above technical solution: The reinforcing part includes symmetrically formed grooves on both sides of the four corners of the box body, a limiting baffle plate integrally fixed inside the groove and capable of bending inward, and a plastic support plate triangularly fixed between the box body and the two limiting baffle plates by a locking component.

[0008] As a further description of the above technical solution: The locking component includes a sliding post integrally fixed on a plastic support plate and extending inward through a limiting baffle, a limiting ring fixed at the inner end of the sliding post and fitting against the outer wall of the limiting baffle, and a vertical sliding groove formed on the limiting baffle for the sliding post to slide in from top to bottom.

[0009] As a further description of the above technical solution: The width of the vertical sliding groove is the same as the diameter of the sliding column, and the diameter of the limiting ring is greater than the width of the vertical sliding groove.

[0010] As a further description of the above technical solution: The plastic support sheet is made of polyimide material.

[0011] As a further description of the above technical solution: A first magnetic piece is fixedly connected to the middle of the side of the upper screw cap facing the front end of the box, and a second magnetic piece is fixedly connected to the top front end of the box, which can be magnetically attracted and fixed to the first magnetic piece.

[0012] As a further description of the above technical solution: The interior of the box is filled with an inner lining pad that covers the lower cover, the limiting baffle, and the plastic support plate.

[0013] As a further description of the above technical solution: The inner side of the upper screw cap is fixedly connected to an upper protective pad facing the inner lining pad.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: In this invention, the original ring-shaped packaging box structure has been scientifically and rationally improved. Rotary grooves, limiting baffles, vertical sliding grooves, plastic support pieces, sliding columns, and limiting rings are installed between the lower base, upper cap, and the four corners of the box body. The plastic support pieces can be fixedly installed between the box body and the two limiting baffles via the sliding columns and limiting rings, forming a triangular reinforcement structure at the corners of the box body. When a load is applied vertically to the packaging box, the four vertically distributed plastic support pieces can actively support and resist the vertical impact load. When a load is applied laterally to the packaging box, due to the triangular support at the corners, the rectangular box body is less likely to deform into a parallelogram. The four limiting baffles can resist the folding and tearing effects of external forces. This structure allows a stable triangular reinforcement structure to be formed at each of the four corners of the packaging box, effectively reducing the occurrence of dents, deformations, and folding tears when the packaging box is subjected to lateral and longitudinal loads, thereby comprehensively improving the compression resistance, impact resistance, and deformation resistance of the ring-shaped packaging box.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 This utility model provides a technical solution: a pressure-resistant packaging box structure, including a lower packaging base 1, an upper screw cap 101 integrally fixed to the upper end of the lower packaging base 1, and a box body 2 bonded and fixed between the lower packaging base 1 and the upper screw cap 101. Reinforcing parts for improving the lateral and longitudinal pressure resistance of the packaging box are provided between the four corners of the lower packaging base 1, the upper screw cap 101 and the box body 2.

[0019] Specifically, such as Figure 1-3 As shown, the reinforcing part includes swivel grooves 201 symmetrically opened on both sides of the four corners of the box body 2, a limiting baffle 202 integrally fixed inside the swivel grooves 201 and bendable inward, and a plastic support piece 3 triangularly fixed between the box body 2 and the two limiting baffles 202 by a locking piece. The plastic support piece 3 is made of polyimide material, which gives the plastic support piece 3 excellent mechanical properties, high temperature resistance and low temperature resistance, thereby meeting the requirements for structural reinforcement of the packaging box.

[0020] The locking mechanism includes a sliding post 301 integrally fixed to the plastic support plate 3 and extending inward through the limiting baffle 202, a limiting ring 302 fixed to the inner end of the sliding post 301 and fitting against the outer wall of the limiting baffle 202, and a vertical sliding groove 203 formed on the limiting baffle 202 for the sliding post 301 to slide in from top to bottom. The width of the vertical sliding groove 203 is the same as the diameter of the sliding post 301, and the diameter of the limiting ring 302 is larger than the width of the vertical sliding groove 203. This structure allows the plastic support plate 3 to be stably slidably fixed between the two limiting baffles 202 in multiple directions, reducing the problem of the plastic support plate 3 shifting and shaking at the corner of the box body 2 when the packaging box is subjected to lateral or longitudinal loads.

[0021] Specifically, such as Figure 1-4 As shown, a first magnetic piece 102 is fixedly connected to the middle of the side of the upper screw cap 101 facing the front end of the box body 2, and a second magnetic piece 204 that can be magnetically fixed to the first magnetic piece 102 is fixedly connected to the top of the front end of the box body 2. When the upper screw cap 101 is closed on the box body 2, the first magnetic piece 102 on the upper screw cap 101 will magnetically adhere to the second magnetic piece 204 on the box body 2, thereby magnetically fixing the upper screw cap 101 to the upper end of the box body 2.

[0022] Specifically, such as Figure 1-3 As shown, the interior of the box 2 is filled with an inner liner pad 4 that covers the lower packaging seat 1, the limiting baffle 202, and the plastic support 3. The inner side of the upper screw cap 101 is fixedly connected to an upper pad 103 facing the inner liner pad 4. The inner liner pad 4 and the upper pad 103 are arranged to flexibly wrap valuable items in all directions between the lower packaging seat 1, the upper screw cap 101, and the box 2, thereby reducing the occurrence of impact scratches, bumps, and breakage of valuable items inside the packaging box.

[0023] Working principle: During use, when installing the plastic support plate 3, the operator can rotate the limiting baffle 202 in the rotating groove 201 into the box body 2. Then, the sliding post 301 on the plastic support plate 3 is aligned and slides downward into the vertical sliding groove 203 of the limiting baffle 202. When the lower end of the plastic support plate 3 contacts the lower bag seat 1, the plastic support plate 3 is triangularly fixed between the box body 2 and the two limiting baffles 202. Then, the inner lining pad 4 can be inserted into the box body 2, thus completing the reinforcement operation of the box body 2. In actual use, when the impact... When an impact load is applied to the upper cap 101, the four plastic support pieces 3 can actively resist the impact load borne by the lower packaging base 1 and the four corners of the upper cap 101, thereby preventing the overall vertical deformation of the box body 2. At the same time, because the four plastic support pieces 3 form a triangular reinforcement structure at the four corners of the box body 2, it is more difficult for the box body 2 to change from a rectangle to a parallelogram under force, effectively improving the strength of the packaging box against folding and tearing when subjected to lateral load, thereby comprehensively improving the compressive strength of the packaging box in both the lateral and longitudinal directions.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
