DETAILED DESCRIPTION
[0023] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0024] like Figure 1 As shown, this embodiment provides an embodiment of a protective cover for a protective pressure plate. In this embodiment, the protective cover includes a cover body 1, in which a protective pressure plate 2 is detachably provided. The protective pressure plate 2 includes a pressure plate connecting piece.
[0025] Preferably, the cover body 1 is a rectangular shell with an open side and a hollow interior. The protective pressure plate 2 is located inside the cover body 1. The cover body 1 completely covers the protective pressure plate 2. The cover body 1 is made of polymethyl methacrylate, which has the advantages of being non-brittle, having stable chemical properties, and being easy to clean and maintain.
[0026] Furthermore, pressure plate connecting piece grooves 3 are provided on both sides of the bottom of the cover body 1 for the pressure plate connecting piece to pass through. When the pressure plate connecting piece of the protective pressure plate 2 rotates, the pressure plate connecting piece exits through the pressure plate connecting piece grooves 3, so that the cover body 1 can also normally cover the protective pressure plate 2 when the pressure plate connecting piece exits, and the pressure plate connecting piece grooves 3 play a limiting role on the pressure plate connecting piece to prevent the pressure plate connecting piece from rotating.
[0027] Furthermore, at least two groups of magnet slots 4 are fixedly installed at both ends of the cover body 1. The magnet slots 4 are fixedly installed at the two ends of the outer side of the cover body 1. Magnets 5 are fixedly connected in the magnet slots 4. The cover body 1 is adsorbed above the protective pressure plate 2 through the magnets 5 in the magnet slots 4, so that the cover body 1 completely covers the protective pressure plate 2 and prevents the cover body 1 from falling off.
[0028] Among them, see Figures 2 to 3An identification plate 6 is slidably installed on the surface of the cover body 1. After the cover body 1 completes the covering, the status of the pressure plate connection in the protective pressure plate 2 is marked by sliding the identification plate 6. A fixing component for fixing the identification plate 6 is fixedly connected to the cover body 1.
[0029] Further, see Figure 4 The identification plate 6 includes at least a first plate body 61 and a second plate body 62. Both the first plate body 61 and the second plate body 62 are provided with marks for different operating states of the protection pressure plate 2. For example, the operating pressure plate indicates "operation" and the exit pressure plate indicates "exit". The first plate body 61 or the second plate body 62 with marks for different operating states of the protection pressure plate 2 is moved to the rectangular hole 71 opened at the top of the mounting seat 7, so that the first plate body 61 or the second plate body 62 is exposed from the rectangular hole 71 and is in a visible state, thereby achieving the purpose of marking the state of the pressure plate connection in the protection pressure plate 2.
[0030] Preferably, the fixing assembly includes a mounting seat 7 fixedly installed on the side of the cover body 1 away from the pressure plate connecting groove 3, the identification plate 6 is slidably installed in the mounting seat 7, and handles 8 for moving the identification plate 6 are fixedly installed on both sides of the identification plate 6. The sliding handle 8 allows the identification plate 6 fixedly connected to the handle 8 through a slider to slide in the mounting seat 7.
[0031] Preferably, a rectangular hole 71 is provided on the top of the mounting seat 7 for exposing the identification plate 6. The interior of the mounting seat 7 is hollow, and sliding grooves 72 are provided on both sides of the mounting seat 7. A slider is fixedly installed between the handle 8 and the identification plate 6 and is slidably installed in the sliding groove 72. When the identification plate 6 slides in the mounting seat 7, the slider slides in the sliding groove 72.
[0032] Furthermore, the fixing assembly also includes a moving rod 9 slidably installed at the center of the identification plate 6. Two groups of rectangular grooves 73 are provided on the top of the mounting seat 7 for the moving rod 9 to pass through. The rectangular grooves 73 are respectively located on both sides of the rectangular hole 71. When the moving rod 9 moves to the rectangular grooves 73 located on both sides of the rectangular hole 71, the moving rod 9 passes through one of the rectangular grooves 73 and moves to above the rectangular groove 73, thereby making the moving rod 9 relatively fixed to the mounting seat 7.
[0033] Further, see Figure 5 A C-shaped seat 10 is fixedly installed at the center of the top of the identification plate 6, and a fixing bolt 11 is fixedly installed at the bottom of the C-shaped seat 10. A threaded hole 12 adapted to the fixing bolt 11 is opened at the top of the identification plate 6, and the moving rod 9 is slidably installed in the C-shaped seat 10.
[0034] It should be noted that the fixing bolts and threaded holes are conventional applications in the prior art, and their detailed structures will not be described in detail in this embodiment, nor will they be shown in the drawings.
[0035] When the cam 73 is in the closed position, the spring 14 is engaged with the spring 14 and the spring 14 is engaged with the spring 14 so that the cam 73 is engaged with the spring 14 and the cam 73 is engaged with the spring 14. When the cam 73 is in the closed position, the spring 14 is engaged with the spring 14 and the cam 73 is engaged with the spring 14. When the cam 73 is in the closed position, the spring 14 is engaged with the spring 14 and the cam 73 is engaged with the spring 14. When the cam 73 is in the closed position, the spring 14 is engaged with the spring 14 and the cam 73 is engaged with the spring 14
[0036] When the utility model is in use, the protective pressure plate 2 is fully covered by the cover body 1, and the cover body 1 is adsorbed on the top of the protective pressure plate 2 by the magnet 5 in the magnet slot 4 to prevent the cover body 1 from falling off. When the pressure plate connecting piece of the protective pressure plate 2 rotates, the pressure plate connecting piece exits through the pressure plate connecting piece slot 3, so that the cover body 1 can normally cover the protective pressure plate 2 when the pressure plate connecting piece exits, and the pressure plate connecting piece slot 3 can also prevent the pressure plate connecting piece from sliding;
[0037] After the cover 1 is completed, the state of the pressure plate connection in the protection pressure plate 2 is marked by sliding the identification plate 6. When the identification plate 6 is moved, the handle 8 is first slid so that the identification plate 6 fixedly connected to the handle 8 by the slider slides in the mounting seat 7. At this time, the slider slides in the slide groove 72, and the first plate body 61 or the second plate body 62 with different operating state marks of the protection pressure plate 2 moves to the rectangular hole 71 opened at the top of the mounting seat 7, so that the first plate body 61 or the second plate body 62 is exposed, thereby achieving the purpose of marking the state of the pressure plate connection in the protection pressure plate 2, realizing protection of the protection pressure plate 2 while taking into account the prevention of misoperation. At the same time, the protection pressure plate 2 is covered with the cover 1 and indicated by the identification plate 6, which can prevent secondary personnel from accidentally throwing or missing the protection pressure plate during the operation of the secondary circuit of the relay protection and safety automatic device, resulting in malfunction or refusal of the protection and safety automatic device, thereby affecting the safe and stable operation of the relay protection and safety automatic device.
[0038] When the identification plate 6 moves, the C-shaped seat 10 fixedly connected to the top of the identification plate 6 by the fixing bolts 11 and the threaded holes 12 also moves, so that the moving rod 9 slidably installed in the C-shaped seat 10 slides in the mounting seat 7. When the moving rod 9 moves to the rectangular grooves 73 on both sides of the rectangular hole 71, the telescopic rod 13 fixedly connected between the moving rod 9 and the C-shaped seat 10 is stretched under the action of the spring 14, so that the moving rod 9 passes through one of the rectangular grooves 73 and moves above the rectangular groove 73, thereby making the moving rod 9 relatively fixed to the mounting seat 7, thereby achieving the purpose of fixing the identification plate 6 and preventing the identification plate 6 from shifting, thereby causing the marking plate body that is inconsistent with the operating state of the pressure plate connecting piece in the protection pressure plate 2 to be exposed outside the rectangular hole 71, affecting the staff's judgment on the working state of the pressure plate connecting piece in the protection pressure plate 2.
[0039] The above detailed description of the specific embodiments of the utility model is intended to be illustrative only, and the utility model is not limited to the specific embodiments described above. For those skilled in the art, any equivalent modifications or substitutions made to the utility model are also within the scope of the utility model. Therefore, equivalent changes, modifications, and improvements made without departing from the spirit and scope of the principles of the utility model should be included within the scope of the utility model.
