DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0033] Please refer to Figures 1-4 ,

[0034] First embodiment:

[0035] The present application provides a technical solution: a safety protection device for electrical equipment maintenance, comprising a frame 1, a baffle 2 is connected in the frame 1, an extension device 3 for different equipment is slidingly connected in the frame 1 and the baffle 2, a splicing device 4 for protecting other directions of the equipment is connected outside the extension device 3 and the frame 1, a reminder device 5 for setting warning signs is installed outside the baffle 2 and the splicing device 4.

[0036] Specifically, as Figures 2-3As shown, the extension device 3 includes two sliding rods 31 and two housings 34. The sliding rods 31 are slidably connected inside the frame 1. One side of each sliding rod 31 is connected to the same support leg 33, and one side of the support leg 33 is connected to a sliding plate 32. The sliding plate 32 is slidably connected inside the baffle 2. By setting the sliding plate 32 and the baffle 2, the sliding plate 32 can slide freely inside the baffle 2 to achieve the extension effect, thereby adapting to different equipment. One housing 34 is connected to the back of the frame 1, and the other housing 34 is connected to the back of the sliding rod 31. The baffle 2 has a cavity, and the length of the sliding plate 32 is slightly less than the length of the cavity. The splicing device 4 includes a support frame 41, a sliding groove 45, and two pull springs 47. A protective plate 42 is installed inside the support frame 41, and a limit post 43 is connected to the outside of the support frame 41. A limit groove 44 is opened inside the limit post 43. A sliding groove 45 is formed inside the housing 34, and a slider 46 is slidably connected inside the sliding groove 45. A limiting post 43 is slidably connected inside the support frame 41, and the length of the limiting post 43 is slightly shorter than the length of the support frame 41. Support plates are symmetrically provided outside the slider 46. One end of two return springs 47 is connected to the bottom of the support plate. By setting the return springs 47, the return springs 47 apply a pulling force to the support plate outside the slider 46, so that the slider 46 can move quickly and return to its original position. The other end of the two return springs 47 is connected to the outside of the housing 34. The force-bearing surface of the slider 46 is set as an arc shape to facilitate compression. The size of the slider 46 is slightly smaller than the size of the limiting groove 44, and the slider 46 is locked in the limiting groove 44. By setting the slider 46 and the limiting groove 44, the limiting groove 44 limits the slider 46 and prevents the slider 46 from shaking or falling off.

[0037] During operation, the sliding rod 31 is pulled to extend within the frame 1, which in turn causes the sliding plate 32 to extend within the baffle 2. Then, the limiting posts 43 outside the two support frames 41 are respectively locked into the corresponding housings 34. The support frames 41 are then pushed further, causing the limiting posts 43 to press against the slider 46. At this time, the slider 46 slides within the sliding groove 45. When the slider 46 corresponds to the position of the limiting groove 44, the return spring 47 applies a pulling force to the slider 46. The pulling force causes the slider 46 to move quickly and reset, so that the slider 46 is locked within the limiting groove 44, thereby achieving protection of the equipment perimeter and effectively covering the surrounding area of ​​the equipment.

[0038] Second embodiment:

[0039] Specifically, such as Figure 4As shown, the reminder device 5 includes three mounting plates 51, two of which are symmetrically arranged on one side of the protective plate 42, and the other mounting plate 51 is connected to the front of the baffle 2. A movable plate 52 is slidably connected inside the mounting plate 51. By setting the mounting plate 51 and the movable plate 52, the mounting plate 51 limits the movable plate 52 to prevent the movable plate 52 from detaching from the mounting plate 51 during use. A handle 53 is connected to the movable plate 52, and a warning sign 54 is connected to the outside of the movable plate 52.

[0040] During operation, the movable plate 52 is inserted into and fixed in the mounting plate 51 by operating the handle 53. When the movable plate 52 is fully embedded in the mounting plate 51, the warning sign located on the outside of the movable plate 52 will warn outsiders. Different warning content can be changed according to different equipment to prevent outsiders from approaching and thus avoid potential safety risks.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
