[0030] The present invention provides a box body that is easy to assemble and disassemble. In order to make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0031] In the description of this utility model, it should be understood that the terms "upper, lower, left, and right" and the like indicating directions or positions are based on the directions or positions shown in the accompanying drawings and are intended solely to facilitate and simplify the description of this utility model and are not to be construed as limiting the scope of this utility model. Furthermore, the terms "installation" and "connection" are to be understood broadly, and those skilled in the art will be able to understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0032] See also Figures 1 to 3 The present invention provides a box that is easy to assemble and disassemble, which is mainly used in the medical industry, specifically in the dental field. The box that is easy to assemble and disassemble is composed of an upper shell 1 and a lower shell that are tightly connected. The lower shell includes a left shell 2, a right shell 3, a wedge-shaped fixing plate 4, a strip-shaped fixing plate 5 and a clamping structure. Specifically, a wedge-shaped fixing plate 4 and a strip-shaped fixing plate 5 are respectively installed on the front and rear inner walls of the left shell 2 and the right shell 3. The wedge-shaped fixing plate 4 and the strip-shaped fixing plate 5 are provided with at least two clamping structures along their respective height or length directions. Each clamping structure is composed of a clamping protrusion 6 and a clamping groove 7 that match each other. The clamping protrusion 6 can be firmly locked in the clamping groove 7 to achieve a stable connection. More specifically, the inner walls of the front sides of the left shell 2 and the right shell 3 are provided with the same wedge-shaped fixing plate 4, and the inner walls of the rear sides of the left shell 2 and the right shell 3 are provided with the same strip-shaped fixing plate 5. Two of the above-mentioned clipping structures are provided in the height direction of the wedge-shaped fixing plate 4, and two of the above-mentioned clipping structures are provided in the length direction of the strip-shaped fixing plate 5.

[0033] In a preferred embodiment, the snap-fit ​​groove 7 is a longitudinal opening, and its opening width gradually decreases from the bottom to the top, which not only facilitates the easy insertion of the snap-fit ​​protrusion 6, but also ensures that once the snap-fit ​​protrusion 6 reaches the top of the groove, it can be locked more firmly, effectively preventing loosening, thereby improving the overall reliability and durability of the box.

[0034] In addition, the box body is also equipped with a support block 8, which is set at the edge of the upper shell 1. When the lower shell is tightly fitted with the upper shell 1, the support block 8 can provide additional support, effectively disperse the pressure, avoid local stress concentration, and further extend the service life of the box body.

[0035] In order to further enhance the structural stability of the box, screw holes 9 are also opened in the upper shell 1. The lower shell can be firmly fixed to these screw holes 9 by screws, providing additional safety protection for the box, which is especially suitable for application scenarios with strict safety performance requirements.

[0036] The box's structural reinforcement also includes added reinforcing ribs 10, which are located on the inner walls of both the upper and lower shells. These ribs not only significantly enhance the box's compressive strength and rigidity, but also effectively prevent deformation or damage under heavy pressure, ensuring stable operation in a variety of harsh environments. Notably, the ribs 10 on the inner wall of the upper shell 1 are arranged in a staggered pattern, maximizing support without sacrificing internal space while maintaining a flat interior, providing users with a more convenient storage experience.

[0037] In order to meet the user's demand for the flexibility of the box, it also includes a movable cover 11, which is connected to the top of the upper shell 1 by a hinged manner. The user only needs to gently open the movable cover 11 to easily access the inside of the box without the tedious disassembly of the entire upper shell 1. This is convenient and fast, and greatly improves work efficiency. It is especially suitable for scenarios where items need to be frequently stored and retrieved.

[0038] In summary, the present invention provides a conveniently assembled and disassembled box. The snap-fit ​​structure is arranged in the height direction of the shoe-shaped fixing plate and the length direction of the strip fixing plate 5. The snap-fit ​​protrusions 6 and snap-fit ​​grooves 7 on the front and rear sides of the lower shell body quickly complete the positioning in two directions. Furthermore, the box body can be quickly locked after simple operations in two dimensions. The user can connect or separate the upper shell body 1 and the lower shell body without using any tools. This not only improves the structural stability and work efficiency of the box body and reduces maintenance costs, but also opens up the possibility of the box body being used in more fields and enhances its adaptability in various environments. Therefore, the present invention effectively overcomes the various shortcomings of the prior art and has a high industrial utilization value.

[0039] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and the utility model concept of the present invention, and all these changes or substitutions should fall within the scope of protection of the present invention.
