[0002] The relay protection pressure plate is also called the protection connection piece or the tripping pressure plate. It is the bridge and link between the protection device and the external wiring, which is related to whether the protection function and the action outlet can function normally. "Power production, safety first", the safe operation of the relay protection system is the most important safety guarantee for the power system, and the safe operation of related equipment in the relay protection system is particularly important. Due to the particularity of equipment such as relay protection devices, a "pressure plate" must be designed on the tripping circuit, which is an important means to ensure the safe operation of the relay protection system. The relay protection pressure plate is a disconnection point visible to the naked eye, which is convenient for operators to judge whether the tripping circuit of the relay protection device can connect the tripping coil of the switch (circuit breaker), which provides great convenience for maintenance and operation.

[0003] However, the existing relay protection pressure plates are usually directly exposed to the outside, and personnel working nearby may accidentally touch them, which may lead to errors in the use of relay protection and accidents. Therefore, the utility model provides a protective cover for the relay protection pressure plate to prevent accidental operation and accidental contact. Utility Model Content

[0014] 3. Beneficial effects

[0015] Compared with the prior art, the advantages of the present invention are:

[0016] (1) This solution can fully protect the pressure plate body through the packaging plate and the cover body to prevent people from accidentally touching the pressure plate body and reduce the occurrence of safety accidents. When the cover body needs to be opened, the person presses the linkage rod with the thumb and index finger together, and the linkage rod cooperates with the L-shaped connecting block to drive the card block one to move to one side, so that the card block two overlapped on the card block one will be separated from it, and then the cover body will automatically move downward due to gravity, thereby fully exposing the pressure plate body, making it convenient for people to operate the pressure plate body.

[0017] (2) In this solution, only when the person presses the linkage rod with the thumb and index finger together, the card block 1 can be fully separated from the card block 2. If only the linkage rod on one side is pressed, the card block 1 and the card block 2 on the other side will still remain overlapped, and the cover body will not be able to open. The action of pressing the linkage rod with the thumb and index finger together is targeted, and the cover body will not open automatically without being noticed, which is safer. In addition, this action is also in line with the operating habits of the human body and can be completed with one hand.

[0018] (3) In this solution, since the ends of block 1 and block 2 that are close to each other are inclined, when a person pushes the open cover upward, block 1 on the cover will force block 2 to move to one side. When block 1 moves upward into place, block 2 will be reset due to the elastic force of the spring. After reset, block 2 will be stuck at the lower end of block 1, thereby keeping the closed cover stable. When closing the cover, the person only needs to move the cover upward. After moving into place, the cover will be automatically locked, making it convenient for the person to operate and use. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0027] Example

[0028] like Figure 1-5 As shown, a relay protection pressure plate malfunction and malcontact protection cover comprises a side door 1 of a power distribution cabinet, a pressure plate body 2 and a mounting frame 3, one side of the side door 1 of the power distribution cabinet is fixedly connected with the pressure plate body 2 and the mounting frame 3, the mounting frame 3 is sleeved on the outside of the pressure plate body 2, one side of the mounting frame 3 is fixedly connected with a packaging plate 4, one side of the mounting frame 3 is slidably connected with a cover body 5, and the cover body 5 is located below the packaging plate 4;

[0029] Both ends of the packaging plate 4 are provided with cavities 41, and the lower end of the cavity 41 is provided with a through hole 42. Both ends of the packaging plate 4 are penetrated and movably connected with a linkage rod 43, one end of the linkage rod 43 is located in the cavity 41 and fixedly connected with a connecting block 44, one side of the connecting block 44 is fixedly connected with a spring 45, one end of the spring 45 is fixed to the inner wall of the cavity 41, the other side of the connecting block 44 is fixedly connected with an L-shaped connecting block 46, one end of the L-shaped connecting block 46 is fixedly connected with a card block 1 47, the upper end of the cover body 5 is fixedly connected with a fixed block 51 at one end, one side of the fixed block 51 is fixedly connected with a card block 2 52, and the card block 2 52 is overlapped on the upper end of the card block 1 47;

[0030] The ends of the clamping block 1 47 and the clamping block 2 52 that are close to each other are inclined.

[0031] When in use, the sealing plate 4 and the cover body 5 can fully protect the pressure plate body 2 to prevent people from accidentally touching the pressure plate body 2, thereby reducing the occurrence of safety accidents. When it is necessary to open the cover body 5, the person presses the linkage rod 43 with the thumb and index finger, and the linkage rod 43 cooperates with the L-shaped connecting block 46 to drive the card block 1 47 to move to one side, so that the card block 2 52 overlapped on the card block 1 47 will be separated from it, and then the cover body 5 will automatically move downward due to gravity, thereby fully exposing the pressure plate body 2, making it convenient for people to operate the pressure plate body 2;

[0032] Only when the person presses the linkage rod 43 with the thumb and index finger together, the card block 1 47 can be fully separated from the card block 2 52. If only the linkage rod 43 on one side is pressed, the card block 1 47 and the card block 2 52 on the other side are still overlapped, and the cover body 5 cannot be opened. The action of pressing the linkage rod 43 with the thumb and index finger together is targeted, and the cover body 5 will not be opened automatically by accident, which is safer. In addition, this action is also in line with the operating habits of the human body, and the operation can be completed with one hand.

[0033] Since the ends of the clamping block 1 47 and the clamping block 2 52 that are close to each other are inclined, when a person pushes the opened cover body 5 upward, the clamping block 1 47 on the cover body 5 will force the clamping block 2 52 to move to one side. When the clamping block 1 47 moves upward into position, the clamping block 2 52 will be reset due to the elastic force of the spring 45. The reset clamping block 2 52 will be clamped at the lower end of the clamping block 1 47, thereby keeping the closed cover body 5 stable. When closing the cover body 5, the person only needs to move the cover body 5 upward, and the cover body 5 will be automatically clamped after moving into position, which is convenient for the person to operate and use;

[0034] The side door 1 of the power distribution cabinet and the main body 2 of the pressure plate are not the main parts of the protective cover, but are just for the convenience of understanding.

[0035] like Figure 3-4As shown, a pair of dovetail grooves 31 are opened on one side of the installation frame 3, and a pair of dovetail blocks 53 are fixedly connected to one side of the cover body 5. The cover body 5 can slide on the installation frame 3 with the dovetail grooves 31 through the connection of the dovetail blocks 53.

[0036] When in use, the dovetail groove 31 and the dovetail block 53 are slidably connected, and the cover body 5 will not separate to one side. The cover body 5 can slide while maintaining a stable connection with the installation frame 3.

[0037] like Figure 5 As shown, one end of the linkage rod 43 extending to the outside is fixedly connected to a contact block 431 .

[0038] When in use, the contact block 431 increases the contact area between the linkage rod 43 and the fingers of the person, thereby improving the comfort of the person when squeezing the linkage rod 43 with combined force.

[0039] like Figure 2-3 As shown, the specific position of the pressing plate body 2 is close to the right side of the installation frame 3.

[0040] When in use, the pressure plate body 2 can be disconnected by turning left. Even in the disconnected state, the cover body 5 and the packaging plate 4 can still protect the pressure plate body 2. The cover body 5 is transparent, which is convenient for personnel to observe the state of the pressure plate body 2.

[0041] In summary, the specific working process of this scheme is as follows: the packaging plate 4 and the cover body 5 can fully protect the pressure plate body 2 to prevent personnel from accidentally touching the pressure plate body 2 and reduce the occurrence of safety accidents. When the cover body 5 needs to be opened, the personnel presses the linkage rod 43 with the thumb and index finger, and the linkage rod 43 cooperates with the L-shaped connecting block 46 to drive the card block 1 47 to move to one side, so that the card block 2 52 overlapped on the card block 1 47 will be separated from it, and then the cover body 5 will automatically move downward due to gravity, thereby fully exposing the pressure plate body 2. The plate body 2 is convenient for personnel to operate the pressure plate body 2. When the personnel pushes the opened cover body 5 upward, the block 1 47 on the cover body 5 will force the block 2 52 to move to one side. When the block 1 47 moves upward into place, the block 2 52 will be reset due to the elastic force of the spring 45. The reset block 2 52 will be stuck at the lower end of the block 1 47, thereby keeping the closed cover body 5 stable. When closing the cover body 5, the personnel only needs to move the cover body 5 upward. The cover body 5 will be automatically clamped after moving into place, which is convenient for personnel to operate and use.

[0042] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
