[0028] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are 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.

[0029] Combine the following Figure 1-Figure 3 The utility model describes a relay protection pressure plate anti-misoperation and miscollision protection device.

[0030] This embodiment provides a relay protection pressure plate to prevent misoperation or miscollision protection device, such as Figure 1-Figure 3 As shown, it includes: a relay protection pressure plate body 1 and a protective cover 2.

[0031] Among them, the protective cover 2 is covered on the relay protection pressure plate body 1, and the protective cover 2 includes a first cover shell 21 and a second cover shell 22. The second cover shell 22 is located above the first cover shell 21, and the second cover shell 22 can be slidably connected with the first cover shell 21 along a first direction. The first direction is the height direction of the first cover shell 21 or the second cover shell 22.

[0032] Specifically, the top and bottom of the first cover shell 21 are both open, which is convenient for covering the relay protection pressure plate body 1 in the first cover shell 21. The top of the first cover shell 21 is open for connecting with the second cover shell 22. A plug-in slot 211 is provided at the top of the first cover shell 21, and the bottom of the second cover shell 22 is adapted to the plug-in slot 211. The second cover shell 22 can be movably arranged in the plug-in slot 211 along the height direction. That is to say, a plug-in slot 211 with a certain depth is provided at the top of the first cover shell 21, and the second cover shell 22 is installed in the plug-in slot 211. By changing the height of the second cover shell 22 embedded in the plug-in slot 211, the overall size of the protective cover 2 can be adjusted, and relay protection pressure plates of different sizes can be protected, thereby avoiding the situation where the entire relay protection pressure plate cannot be completely covered due to size mismatch, thereby improving the effect of protecting the relay protection pressure plate and improving the versatility of the protective cover 2.

[0033] Optionally, the first cover shell 21 and the second cover shell 22 are both made of transparent acrylic material.

[0034] like Figure 2 As shown, the second cover shell 22 is sealed at the top and open at the bottom. The connection between the first cover shell 21 and the second cover shell 22 is achieved by matching the bottom of the second cover shell 22 with the plug-in slot 211 of the first cover shell 21. The overall size of the protective cover 2 can be adjusted by adjusting the depth of the second cover shell 22 inserted into the plug-in slot 211 along the height direction to adapt to relay protection pressure plates of different sizes.

[0035] In this embodiment, a positioning structure is also included. The positioning structure is arranged between the first cover shell 21 and the second cover shell 22. The positioning structure includes a positioning bolt 212 and a positioning hole. The positioning hole is arranged on the first cover shell 21, and the positioning hole is connected to the plug-in slot 211. The positioning bolt 212 is arranged in the positioning hole. The end of the positioning bolt 212 abuts against the second cover shell 22, which is used to fix the second cover shell 22 in the plug-in slot 211.

[0036] like Figure 2 As shown, a positioning hole is opened on the outer side of the first cover shell 21, and the positioning hole can be a threaded hole. The positioning bolt 212 is installed in the threaded hole. By rotating the positioning bolt 212, its end is abutted against the outer wall of the second cover shell 22 in the plug-in slot 211, so that the second cover shell 22 is fixed in the plug-in slot 211 after the height is adjusted.

[0037] Furthermore, a pair of limit blocks 213 are relatively disposed on the top of the first cover shell 21 , and a pair of slide grooves 221 are relatively disposed on both sides of the second cover shell 22 , and the limit blocks 213 are adapted to the slide grooves 221 .

[0038] With such arrangement, during the process of adjusting the second cover shell 22 in the height direction, the sliding cooperation between the limit block 213 and the slide groove 221 ensures that the second cover shell 22 is lifted and lowered in a straight line without being deflected. By setting the length of the slide groove 221, it can be used as a stroke limit for the second cover shell 22, which is used to limit the moving distance of the second cover shell 22, thereby preventing the second cover shell 22 from escaping from the plug-in slot 211.

[0039] In some embodiments, a sealing ring 214 is provided in the plug-in slot 211, and the sealing ring 214 is in sliding contact with the outer side of the second cover shell 22; the sealing ring 214 can be made of rubber material, and the sealing ring 214 will fit on the surface of the second cover shell 22, thereby improving the sealing effect between the first cover shell 21 and the second cover shell 22, ensuring the protective effect of the protective cover 2 on the relay protection pressure plate body 1, and preventing dust from entering the first cover shell 21 and the second cover shell 22.

[0040] In this embodiment, a pair of limit plates 23 are relatively arranged in the first cover shell 21, and screws 24 are respectively arranged on both sides of the first cover shell 21. One end of each screw 24 passes through the first cover shell 21 and is connected to the corresponding limit plate 23. The screw 24 can drive the limit plate 23 to move along the second direction by rotating. The second direction is the length direction of the screw 24.

[0041] In this arrangement, by rotating the two screws 24 at the same time, the rotation of the screws 24 drives the limit plate 23 to move in the first cover shell 21, driving a pair of limit plates 23 close to the relay protection pressure plate body 1 until the limit plates 23 are tightly fitted to the surface of the relay protection pressure plate body 1, thereby fixing the protective cover 2 to the relay protection pressure plate body 1.

[0042] In some embodiments, an anti-slip structure 4 is provided on the inner side of the limit plate 23 to increase the friction between the limit plate 23 and the surface of the relay protection platen body 1, so as to improve the stability of the connection between the two. Figure 2 As shown, the anti-skid structure 4 can be a plurality of anti-skid strips arranged on the inner side of the limiting plate 23 , or a plurality of anti-skid protrusions arranged on the inner side of the limiting plate 23 .

[0043] Furthermore, guide rods 25 are provided on both sides of the first cover shell 21 , the guide rods 25 are slidably connected to the first cover shell 21 along the second direction, the guide rods 25 are spaced apart from the screw rod 24 , and the guide rods 25 penetrate the first cover shell 21 and are connected to the limit plate 23 .

[0044] With such arrangement, the limit plate 23 will drive the guide rod 25 to slide in the first cover shell 21 when it moves, and the guide rod 25 serves to limit the moving path of the limit plate 23, thereby preventing the limit plate 23 from deflecting or rotating when it moves, and ensuring the reliability of the connection between the limit plate 23 and the relay protection pressure plate body 1.

[0045] In this embodiment, the inner walls of the first cover shell 21 and the second cover shell 22 are both provided with insulating pads 3 to improve the safety of the protection of the relay protection pressure plate body 1 and avoid the situation where the first cover shell 21 and the second cover shell 22 are conductive due to leakage of the relay protection pressure plate body 1.

[0046] When the utility model is in use, firstly rotate the positioning bolt 212. When the positioning bolt 212 is out of contact with the second cover shell 22, pull the second cover shell 22 along the height direction, and the second cover shell 22 slides in the plug-in slot 211. At the same time, the limit block 213 slides in the slide slot 221. When the second cover shell 22 moves to a suitable position, rotate the positioning bolt 212 in the opposite direction until the positioning bolt 212 abuts against the surface of the second cover shell 22. Then, fix the first cover shell 21 and the second cover shell 22 and put them on the relay protection pressure plate. The two screw rods 24 are rotated at the same time. The rotation of the screw rods 24 will drive the limit plate 23 to move towards the direction close to the relay protection pressure plate body 1. When moving, the limit plate 23 will drive the guide rod 25 to slide in the first cover shell 21 until the inner side of the limit plate 23 is tightly attached to the surface of the relay protection pressure plate body 1, thereby firmly connecting the protective cover 2 with the relay protection pressure plate body 1. By limiting the first cover shell 21 and the second cover shell 22 on the relay protection pressure plate body 1, the relay protection pressure plate body 1 is protected.
