[0021] Clearly, the described embodiments are merely a part of the embodiments of the present application, but not all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0022] In the description of the present application, it should be pointed out that the orientation or positional relationship indicated by the terms "vertical", "upper", "lower", "horizontal" and the like is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0023] In the description of the present application, it should be pointed out that, unless otherwise explicitly specified and limited, the terms "set", "mount", "connected", "connected" should be broadly understood, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication between two elements inside. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0024] Please refer to Figures 1-5 The present application provides a technical scheme: a shell fixing structure of a switch device, comprising a fixing seat 100 and a device shell 200, the fixing seat 100 is provided with a mounting groove 101 on the upper side, the device shell 200 is arranged in the mounting groove 101, the inner wall of the mounting groove 101 is provided with a positioning block 1011, the side of the device shell 200 is provided with a positioning groove 201, the positioning block 1011 is embedded in the positioning groove 201, and the positioning groove 201 is provided with a fixed jack 2011. The positioning block 1011 and the positioning groove 201 have the effect of positioning, and the fixed jack 2011 is used for fixing the device shell 200.

[0025] Furthermore, the fixed base 100 has a movable groove 102 on its side. A movable plate 300 and a sliding column 301 are disposed within the movable groove 102. The sliding column 301 passes through the movable plate 300 and is fixed to the movable groove 102. A connecting block 3011 is provided at the end of the sliding column 301. An elastic component 302 is fixed between the connecting block 3011 and the movable plate 300. A fixing rod 303 is fixed on the movable plate 300 and is inserted into the fixing socket 2011 to restrict the electrical housing 200. By pulling the movable plate 300 outward, the movable plate 300 causes the fixing rod 303 to exit from the fixing socket 2011, thus eliminating the need for disassembly and assembly of the electrical housing 200. The electrical housing 200 can then be removed from the mounting groove 101. The operation is simple and easy to understand.

[0026] Furthermore, a pull ring 304 is fixed in the middle of the movable plate 300, and the pull ring 304 is mainly for the convenience of pulling the movable plate 300.

[0027] Furthermore, a fixing plate 103 is provided below the movable groove 102, and a fixing hole 1031 is provided on the fixing plate 103. The fixing plate 103 and the fixing hole 1031 are provided for installing the fixing seat 100.

[0028] Furthermore, an auxiliary block 202 is provided above the positioning groove 201. The auxiliary block 202 is mainly used to facilitate the removal of the electrical housing 200 from the mounting groove 101.

[0029] Furthermore, the elastic component 302 is a spring, which is sleeved on the sliding column 301. It can also be replaced with other elastic components 302, such as elastic airbags.

[0030] Furthermore, the connecting block 3011 is threaded onto the slide column 301, so that the connecting block 3011 can be removed from the slide column 301, and then the movable plate 300 can be easily removed.

[0031] In summary, during installation, simply hold the pull ring 304 and pull it outwards. This causes the pull ring 304 to move the movable plate 300 outwards, compressing the elastic component 302 and causing it to contract. Then, align the positioning groove 201 on the electrical housing 200 with the positioning block 1011 and insert it, allowing the electrical housing 200 to fit into the mounting groove 101. Release the pull ring 304, and the elastic component 302 will push the movable plate 300 back, causing it to move the fixing rod 303 into the fixing hole 2011 on the electrical housing 200, thus completing the installation of the electrical housing 200. For disassembly, simply pull the movable plate 300 again to pull the fixing rod 303 out of the fixing hole 2011, and then remove the electrical housing 200 from the mounting groove 101. The operation is simple and easy to understand.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
