[0026] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0027] It should be noted that the terms "including" and "having" and any variations thereof in the specification and claims of the present utility model are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally includes steps or units that are not listed, or optionally includes other steps or units inherent to these processes, methods, products or devices. Terms such as "setting" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral body; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. The directions or positions indicated by the terms "upper", "lower", "left", "right", "front", "back", "bottom", etc. are based on the directions or positions shown in the drawings, which are only for the convenience of description and cannot be understood as limitations on the present technical solution.

[0028] It should be noted that during the assembly process of the power supply housing, the existing screw fixing method has some obvious problems. First, it is not convenient to quickly and firmly install the shell cover on the top of the main housing, and the screw fixing requires a cumbersome tightening process, which not only increases the difficulty of installation, but also reduces the efficiency of installation. There is an urgent need for a power supply housing that can be quickly installed.

[0029] like Figure 1 As shown, this embodiment provides a screw structure, and the screw structure 3 connects the upper shell 1 and the lower shell 2 of the power housing to achieve a tight connection between the upper shell 1 and the lower shell 2 of the power housing. The screw structure 3 not only ensures the stability and safety of the power housing installation, but also greatly improves the installation efficiency and user experience.

[0030] Specifically, it includes a screw body 31, a blocking portion 32 is provided in the middle of the screw body 31, the circumferential outer wall of the screw body 31 is covered with an umbrella skirt 33, and the umbrella skirt 33 of the upper part of the screw body 31 is opposite to the umbrella skirt 33 of the lower part of the screw body 31, so as to facilitate the rapid installation of the upper shell 1 and the lower shell 2 of the power supply shell.

[0031] The blocking portion 32 can effectively prevent the screw body 31 from being screwed in too much, thereby ensuring that the length of the screw body 31 screwed in the upper shell 1 and the lower shell 2 of the power supply housing is consistent, thereby ensuring that the power supply housings are tightly connected. The blocking portion 32 can also provide additional support for the power supply housing, thereby enhancing the overall structural strength of the power supply housing.

[0032] The circumferential outer wall of the screw body 31 is covered with an umbrella skirt 33, and the umbrella skirt 33 of the upper part of the screw body 31 is opposite to the umbrella skirt 33 of the lower part of the screw body 31. This relative design allows the screw body 31 to be quickly screwed into the power supply housing when it is screwed into the power supply housing, and after being screwed into the power supply housing, the screw body 31 cannot be pulled out, and the upper and lower umbrella skirts 33 can cooperate with each other to form a mechanism similar to "locking", thereby ensuring that the connection between the upper shell 1 and the lower shell 2 of the power supply housing is more stable.

[0033] In a preferred embodiment, the diameter of the blocking portion 32 is greater than the diameter of the umbrella skirt 33. The blocking portion 32 has a larger diameter, and when the screw body 31 is screwed into the power supply housing, the blocking portion 32 will contact the upper shell 1 and the lower shell 2 of the power supply housing to form a stable support point, ensuring that the connection between the upper shell 1 and the lower shell 2 of the power supply housing is more stable.

[0034] The distances between adjacent sheds 33 are the same or different. When the distances between adjacent sheds 33 are the same, the resistance during installation can be reduced, making it easier for the screw body 31 to be screwed into the hole of the power supply housing. When the distances between adjacent sheds 33 are different, the friction between the screw body 31 and the hole of the power supply housing can be increased, so that the upper shell 1 and the lower shell 2 of the power supply housing can be stably installed.

[0035] The material of the screw structure 3 is hard metal, which can withstand greater force and pressure. This makes the screw structure 3 less likely to deform or be damaged when screwed into the power supply housing, and after being screwed into the power supply housing, it can be in close contact with the power supply housing to ensure that the power supply housing will not fall off.

[0036] like Figure 2-Figure 4 As shown, this embodiment provides a simple power supply housing that can be quickly installed. The upper housing 1 and the lower housing 2 can be quickly installed through the screw structure 3, thereby improving the installation efficiency.

[0037] Specifically, it includes an upper shell 1, a lower shell 2 and the screw structure 3, the lower part of the screw structure 3 is fixed to the lower shell 2 by injection molding, and the upper part of the screw structure 3 is interference fit with the upper shell 1 to achieve rapid installation of the upper shell 1 and the lower shell 2.

[0038] The lower part of the screw structure 3 is fixed to the lower shell 2 by injection molding, and the injection molding fixation method forms a tight connection between the lower part of the screw structure 3 and the lower shell 2, which not only ensures the stability of the connection, but also avoids the situation where the screw becomes loose or falls off during the installation process. The upper part of the screw structure 3 is connected to the upper shell 1 by interference fit, and a tight fit is formed between the upper shell 1 and the upper part of the screw structure 3, thereby realizing the rapid installation of the upper shell 1 and the lower shell 2.

[0039] The setting of the screw structure 3 makes the installation process between the upper shell 1 and the lower shell 2 simple and fast. The user only needs to align the upper shell 1 with the screw structure 3 and press down slightly to complete the installation, and the upper shell 1 and the lower shell 2 are tightly connected. This installation method not only reduces the installation steps, but also improves the installation efficiency, making the assembly of the power supply housing more convenient.

[0040] In one embodiment, the lower shell 2 is provided with a lower mounting column 21, and the lower mounting column 21 is provided with a lower mounting hole 22. The lower portion of the screw structure 3 is provided in the lower mounting hole 22 and is fixed to the lower mounting hole 22 by injection molding. The lower shell 2 serves as the basis of the power supply housing and has a stable supporting function. A plurality of lower mounting columns 21 are provided on the lower shell 2. The lower mounting columns 21 not only play a role in strengthening the structure of the lower shell 2, but also each lower mounting column 21 is provided with a lower mounting hole 22. These lower mounting holes 22 are used to place the lower portion of the screw structure 3.

[0041] The upper shell 1 is provided with an upper mounting column 11, and the upper mounting column 11 is provided with an upper mounting hole 12. The upper portion of the screw structure 3 is disposed in the upper mounting hole 12 and is interference-fitted with the upper mounting hole 12. The upper mounting column 11 corresponds to the lower mounting column 21 on the lower shell 2, and is used to ensure that the upper shell 1 and the lower shell 2 can be accurately aligned during installation.

[0042] In one embodiment, the distance between the upper mounting hole 12 and the lower mounting hole 22 is not less than the blocking portion 32 of the screw structure 3. The purpose of this setting is to ensure that the blocking portion 32 is arranged between the upper shell 1 and the lower shell 2, and the edges of the upper shell 1 and the lower shell 2 can fit together without being blocked by the blocking portion 32.

[0043] The diameter of the blocking portion 32 is larger than the aperture of the upper mounting hole 12, and the diameter of the blocking portion 32 is larger than the aperture of the lower mounting hole 22. The diameter setting of the blocking portion 32 ensures that the blocking portion 32 will not be screwed into the upper mounting hole 12 and the lower mounting hole 22, and can effectively prevent the screw body 31 from being screwed in excessively, thereby ensuring that the screw body 31 is screwed into the upper shell 1 and the lower shell 2 to the same length.

[0044] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to the utility model.

[0045] The above is an exemplary description of the utility model patent in conjunction with the accompanying drawings. It is obvious that the implementation of the utility model patent is not limited to the above-mentioned method. As long as various improvements are made by adopting the method concept and technical solution of the utility model patent, or the concept and technical solution of the utility model patent are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
