[0027] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0028] like Figure 1 to Figure 2 As shown, the utility model provides a combined low-voltage cabinet with a wiring safety isolation device, including a cabinet body 1, which is an assembled structure, and a movable rear plate 2 is arranged behind the cabinet body 1, and a square installation opening 3 and a cover plate 4 with the same shape as the installation opening 3 are arranged on the rear plate 2, and the shape is a conventional geometric shape, which is convenient for cutting and processing. The cover plate 4 is detachably provided with a wiring board 5 on the plane inside the cabinet body 1, and the function and purpose of the wiring board 5 is to collect and organize the circuits and electrical components. A pair of insulating travel plates 6 are hinged on the plane of the rear plate 2 away from the wiring board 5, and the pair of travel plates 6 are arranged at the two side edges of the installation opening 3 in the vertical direction, and the pair of travel plates 6 are hinged in the horizontal direction, and the cover plate 4 can slide on the travel plate 6. When the cover plate 4 slides on the travel plate 6, the wiring board 5 is brought out at the same time, so that the entire wiring device is isolated separately, so that it is safer and more convenient to replace the circuits and electrical components. The arrangement of a pair of travel plates 6 is to assist in adjusting the circuit under live working conditions, and of course the entire wiring device can also be directly taken out.

[0029] like Figure 3 and Figure 5 As shown, a first travel groove 61 is provided at both ends of the travel plate 6 in a direction away from the cover plate 4. The purpose of the first travel groove 61 is to isolate the cover plate 4 from the assembly of the cabinet 1. In addition, the travel plate 6 is made of rubber, so that a separate working area with an insulating environment is formed, making it safer to adjust the circuits and components. A second travel groove 62 is provided on the travel plate 6 in a direction perpendicular to the first travel groove 61. With this arrangement, when the cover plate 4 moves to the terminal end of the first travel groove 61, it can be moved in the direction of the second travel groove 62, and the entire cover plate 4 can be taken out for convenient work as needed. Slide blocks 41 for sliding in the first travel groove 61 and the second travel groove 62 extend outward on both sides of the end surface of the cover plate 4. The entire sliding depends on the cooperation of the slide block 41 and the groove, and the sliding is smooth and convenient.

[0030] In order to facilitate the positioning and alignment of the cover plate 4 at the installation opening 3 when removing and installing, and to prevent it from falling off due to sudden pulling out when removing, a certain blockage is required, which also serves as a certain warning. The blockage is a flexible protrusion 63 provided on the side wall of the second travel groove 62 and at the intersection with the first travel groove 61.

[0031] The flexible protrusion 63 is hemispherical, and the material of the protrusion can be selected from plastic, silicone and other materials. It plays a certain blocking role without squeezing the surface of the cover plate 4

[0032] like Figure 2 and Figure 4 As shown, in order to prevent the travel plate 6 from occupying the space of the cabinet 1 when not in use, a receiving cavity 21 for accommodating the travel plate 6 is provided on the rear plate 2, so that the overall appearance looks more regular and neat. Damping shafts 65 are installed at both ends of the travel plate 6. Through the function of the damping shafts 65, the travel plate 6 can be stabilized in space, and such stability can more firmly support the cover plate 4. A buckle groove 64 is provided on the travel plate 6, which is also convenient for the hand to turn to cover and unfold, and is convenient for the operator to use.

[0033] like Figure 6 As shown, in order to better fix the cover plate 4 at the installation opening 3, magnetic strips 42 are fixedly arranged on both sides of the cover plate 4. The entire cabinet 1 is made of metal material, so the cover plate 4 is more stably fixed by the adsorption of the magnetic strips 42. The circuit and the electrical appliance themselves also play a role in fixing.

[0034] The cover plate 4 is fixedly provided with a support and fixing column 7, and the wiring board 5 is fixedly provided with a sleeve 8 adapted to the support and fixing column 7. By means of such a sleeve arrangement, the flexibility of the wiring board 5 is further increased. Under appropriate on-site conditions, the wiring board 5 can also be taken out separately, and the required circuits and electrical components can be placed, and then fixed by sleeve arrangement. The material of the travel plate 6, the sleeve 8 and the support and fixing column 7 is selected from conventional insulating rubber. This makes material selection convenient and the production cost low.

[0035] In summary, the embodiment of the present application discloses a combined low-voltage cabinet with a wiring safety isolation device, wherein an installation opening 3 is provided through a rear plate 2, and then a cover plate 4 is provided at the installation opening 3, a wiring board 5 is connected to the cover plate 4, and a travel plate 6 is provided at the installation opening 3. By moving the spatial position of the cover plate 4, the entire wiring device is isolated, and the travel plate 6 is made of insulating materials such as rubber, so as to achieve the effect of safety isolation. The problem of inconvenience and unsafety in replacing circuits and components in a live state is solved.

[0036] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
