[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1 - Figure 3 The utility model provides an embodiment: a modular low-voltage switch cabinet that is easy to splice, including a cabinet body 1, a support plate 2 is slidably connected to the lower surface of the cabinet body 1, a connecting seat 3 is fixedly connected to the lower surface of the support plate 2, a first connecting rod 4 is fixedly connected to the inside of the connecting seat 3, a connecting plate 5 is rotatably connected to the outer wall of the first connecting rod 4, a second connecting rod 7 is rotatably connected to the inside of the connecting plate 5, a fixed seat 6 is fixedly connected to the outer wall of the second connecting rod 7, a sliding rod 8 is fixedly connected to the outer wall of the fixed seat 6, a first spring 9 is sleeved on the outer wall of the sliding rod 8, a fixed plate 10 is slidably connected to the outer wall of the sliding rod 8, a bottom plate 11 is fixedly connected to the lower surface of the fixed plate 10, a sliding seat 12 is fixedly connected to the outer wall of the fixed seat 6, and a first spring 9 is sleeved on the outer wall of the sliding rod 8. The outer wall is slidably connected to a limit plate 13, the outer wall of the limit plate 13 is fixedly connected to the upper surface of the bottom plate 11, and a support assembly is arranged on the upper surface of the limit plate 13; the support assembly comprises a sleeve 14, the lower surface of the sleeve 14 is fixedly connected to the upper surface of the limit plate 13, the interior of the sleeve 14 is slidably connected to a support column 15, the upper surface of the support column 15 is fixedly connected to the lower surface of the support plate 2, a second spring 16 is arranged inside the sleeve 14, one end of the second spring 16 is fixedly connected to the interior of the sleeve 14, and the other end of the second spring 16 is fixedly connected to the lower surface of the support column 15; one end of the first spring 9 is fixedly connected to the outer wall of the fixing seat 6, and the other end of the first spring 9 is fixedly connected to the outer wall of the fixing plate 10;

[0024] Specifically, when an external force acts on the switch cabinet, the support plate 2 can be transmitted to the support column 15. The support column 15 slides inside the sleeve 14 and compresses the second spring 16 at the same time. This process preliminarily buffers the external force and provides a first layer of protection for the internal components of the switch cabinet. As the support plate 2 continues to move downward, the connecting seat 3 pushes the connecting plate 5, and then pushes the fixed seat 6. This allows the slide seat 12 to slide inside the limit plate 13. At the same time, the first connecting rod 4 and the second connecting rod 7 are respectively fixed between the connecting seat 3 and the fixed seat 6, which effectively limits the movement range of the connecting plate 5, thereby enhancing stability. When the fixed seat 6 slides, the first spring 9 can be further compressed. The compression of the first spring 9 provides a second layer of buffering for the internal components of the switch cabinet, further reducing the impact of external forces on them.

[0025] Reference Figure 1 , Figure 2 and Figure 4 , both sides of the outer wall of the bottom plate 11 are fixedly connected with a base 17, and the upper surface of the base 17 is fixedly connected with a lower rail 18; the upper surface of the lower rail 18 is fixedly connected with an upper rail 19, and the interior of the lower rail 18 is slidably connected with a slider 20, and the outer wall of the slider 20 is slidably connected to the interior of the upper rail 19; the outer wall of the slider 20 is fixedly connected with a slide plate 24, and the outer wall of the slide plate 24 is slidably connected to the interior of the upper rail 19; the outer wall of the slide plate 24 is rotatably connected with a pulley 21, and the outer wall of the pulley 21 is slidably connected to the interior of the lower rail 18; the outer wall of the slider 20 is fixedly connected with a support seat 22, and the lower surface of the support seat 22 is slidably connected to the upper surface of the upper rail 19, and the interior of the slider 20 is threadedly connected with a fixing bolt 23;

[0026] Specifically, by pushing the cabinet 1, the support seat 22 will drive the pulley 21 to slide in the lower slide rail 18, and at the same time, the slider 20 will slide synchronously in the upper slide rail 19. This not only ensures the stability and accuracy of the movement of the cabinet 1, but also greatly reduces the friction between the cabinet 1 and the slide rail. When the cabinet 1 is moved to a predetermined position, the fixing bolt 23 will be rotated to fix the slider 20. This not only facilitates the adjustment of the position of the switch cabinet, but also provides great convenience for the assembly and installation of the switch cabinet. At the same time, the convenience of the switch cabinet is greatly improved, making the maintenance and upgrading of the power system easier.

[0027] Working principle: when it is necessary to reduce the impact on the switch cabinet, the force is transmitted to the support column 15 through the support plate 2, so that the support column 15 can compress the second spring 16 while sliding inside the sleeve 14, so as to initially buffer the cabinet body 1, and then the connecting seat 3 can push the connecting plate 5 while the support plate 2 moves downward, so that the connecting plate 5 can push the fixed seat 6, and then drive the slide seat 12 to slide inside the limit plate 13, wherein the first connecting rod 4 and the second connecting rod 7 are respectively fixed between the connecting seat 3 and the fixed seat 6, so that the first connecting rod 4 and the second connecting rod 7 can limit the connecting plate 5 to a certain extent, and then the first spring 9 can be compressed while sliding through the fixed seat 6, so that the first spring 9 can further buffer the cabinet body 1, thereby reducing the switch cabinet. The effect of affecting the internal components improves the stability of the switch cabinet and ensures the safe use of the internal components. When the position of the switch cabinet needs to be adjusted, the cabinet body 1 is placed on the support seat 22 and the cabinet body 1 is pushed at the same time, so that the support seat 22 can be driven by the slide plate 24 to drive the pulley 21 to slide inside the lower rail 18, and the support seat 22 can also drive the slider 20 to slide inside the upper rail 19, thereby moving the cabinet body 1, wherein the pulley 21 can reduce the friction between the slider 20 and the lower rail 18 and the upper rail 19. When the cabinet body 1 reaches a specific position, the fixing bolt 23 is rotated so that the fixing bolt 23 can fix the slider 20, thereby achieving the effect of facilitating the adjustment of the position of the switch cabinet and facilitating assembly, improving the convenience of the switch cabinet and facilitating the splicing and installation of the switch cabinet.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
