[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 2-Figure 5 The present invention provides a split-type AC dual power switching device, comprising a dual power switching device body 1 and a mounting base 2. Mounting assemblies are fixedly connected to both ends of the mounting base 2. The mounting assemblies include mounting brackets 10 fixedly mounted to both ends of the mounting base 2. Mounting holes 11 are defined on the surface of the mounting brackets 10. The mounting assemblies allow the mounting base 2 to be fixed in its intended use position. When installation is required, the user can secure the mounting brackets 10 to the mounting base using bolts inserted through the mounting holes 11, thereby securing the mounting base 2 in its intended use position.

[0022] Preferably, a positioning frame 3 is fixedly connected to the back of the dual power switching device body 1, and the inner wall of the positioning frame 3 is slidably connected to the surface of the mounting seat 2. A positioning block 4 for fixing the dual power switching device body 1 is provided on the front of the mounting seat 2 and on one side of the dual power switching device body 1. An elastic connection component is provided between the positioning block 4 and the mounting seat 2. The positioning block 4 is movably installed on the front of the mounting seat 2 through the elastic connection component. The elastic connection component includes a fixing groove 5 opened on the front of the mounting seat 2. The back of the positioning block 4 is slidably connected to the inner cavity of the fixing groove 5. A compression spring 6 is fixedly installed on the back of the positioning block 4, and the end of the compression spring 6 away from the positioning block 4 is fixedly connected to the inner wall of the fixing groove 5.

[0023] By using the positioning block 4 in conjunction with the elastic connection component, when the dual power switching device body 1 needs to be installed and fixed on the mounting seat 2, the user can plug the positioning frame 3 into the fixing seat. When the positioning frame 3 is moved, its inner wall will press the positioning block 4, and the movement of the positioning block 4 will squeeze the compression spring 6. When the positioning frame 3 is completely stuck on the surface of the mounting seat 2, the positioning block 4 will be exposed from the inner cavity of the positioning frame 3. At this time, the reaction force generated by the contraction of the compression spring 6 will push the positioning block 4 toward the outside of the fixing groove 5, so that one side of the positioning block 4 is tightly fixed to one end of the dual power switching device body 1.

[0024] When disassembling the dual power switching device body 1 , the user only needs to reverse the above-mentioned installation steps.

[0025] A guide assembly is provided between the back of the positioning block 4 and the inner cavity of the fixing slot 5 to enhance the stability of the positioning block 4. The guide assembly comprises a guide rod 7 fixedly mounted on one side of the inner cavity of the fixing slot 5. A guide hole 8 is provided on the back of the positioning block 4 at a position corresponding to the guide rod 7. One end of the guide rod 7 is slidably engaged with the inner cavity of the guide hole 8. The provision of the guide assembly enhances the stability of the positioning block 4. When the positioning block 4 moves, it drives the guide hole 8 on its back to slide on the surface of the guide rod 7.

[0026] In this embodiment, the compression spring 6 is sleeved on the surface of the guide rod 7. The guide rod 7 can play an auxiliary supporting role for the compression spring 6 to prevent the compression spring 6 from bending sideways when being squeezed.

[0027] It is worth noting that the surface of the positioning block 4 is provided with an oblique cutout 9, and the inner wall of the positioning frame 3 is slidably connected to the surface of the oblique cutout 9. The front of the positioning block 4 passes through the fixing groove 5 and extends to the outside of the fixing groove 5, and one side of the positioning block 4 is in contact with the positioning frame 3 and one end of the dual power switching device body 1. The provision of the oblique cutout 9 facilitates the positioning frame 3 to squeeze the positioning block 4 during the sliding installation process to cause it to move. The contact between one side of the positioning block 4, the positioning frame 3 and one end of the dual power switching device body 1 can tightly fix the dual power switching device body 1.

[0028] Furthermore, a limiting assembly is provided between the inner wall of the positioning frame 3 and the mounting seat 2 for limiting the positioning frame 3. The limiting assembly includes a limiting rod 12 fixedly installed on the upper and lower sides of the inner cavity of the positioning frame 3. The upper and lower sides of the mounting seat 2 are provided with limiting grooves 13 adapted to the limiting rod 12. The surface of the limiting rod 12 is slidably connected to the inner wall of the limiting groove 13.

[0029] By setting the limiting component, the stability of the movement of the positioning frame 3 can be improved. When the positioning frame 3 moves, it will drive the limiting rod 12 to slide in the inner cavity of the limiting groove 13. In addition, through the coordinated use of the limiting component and the positioning block 4, the positioning frame 3 can also be limited to prevent it from falling off from the surface of the mounting seat 2 when it is installed and fixed.

[0030] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
