Description

Technical Field

[0001] This utility model relates to the field of relay protection technology, specifically a relay protection pressure plate device. Background Technology

[0002] Protective pressure plates, also called protective connectors or trip pressure plates, are the bridges and links connecting protective devices to external wiring. They are crucial to the proper functioning of the protection and whether the action outputs can function correctly. Based on the different positions of the pressure plates connected to the secondary circuit of the protective device, they can be divided into two main categories: protective function pressure plates and output pressure plates. Protective function pressure plates enable certain functions of the protective device (such as enabling and disabling main protection, distance protection, zero-sequence protection, etc.). Protective pressure plates effectively protect electrical equipment in daily life. However, during use, maintenance personnel need to manually rotate the protective pressure plates to disconnect the power. During rotation, it is easy to touch conductive parts, posing a significant safety hazard. Furthermore, protective pressure plates that are exposed outside the electrical cabinet have limited protective performance.

[0003] Chinese utility model patent CN221226042U discloses a relay protection pressure plate device, including a relay protection pressure plate body. A first connector is fixedly installed on one side of the relay protection pressure plate body, and a second connector is fixedly installed on another side. An adjusting ring is detachably installed on one side of the first connector, and a connecting arm is fixedly connected to one side of the adjusting ring. The second connector is engaged by a snap-fit ​​groove on a snap-fit ​​claw, thereby achieving the effect of circuit connection. When the circuit is disconnected, the tilt angle of the adjusting ring is adjusted to disengage the snap-fit ​​claw. The inner surface of the snap-fit ​​groove is provided with multiple evenly spaced connecting balls. This arrangement serves two purposes: first, it increases the smoothness of the engagement, allowing for better contact with the surface of the second connector; second, it reduces friction after engagement, thereby improving the service life of the snap-fit ​​claw during circuit switching and ultimately increasing the overall service life of the device.

[0004] Existing relay protection pressure plate devices mostly use a sealed protective cover to cover the surface of the relay protection pressure plate body. When the operator needs to adjust the continuity of the connector circuit, the sealed protective cover must be removed first. The operation process is cumbersome and time-consuming, which greatly reduces the efficiency of circuit adjustment.

[0005] Therefore, this utility model provides a relay protection pressure plate device to solve the above problems. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a relay protection pressure plate device, which solves the aforementioned problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a relay protection pressure plate device, comprising a relay protection pressure plate body, two sets of connector bodies fixedly connected to the upper surface of the relay protection pressure plate body, and a sealing mechanism fixedly connected to the upper surface of the relay protection pressure plate body. A limiting mechanism is fixedly connected to the outer surface of the sealing mechanism. The sealing mechanism includes a sealing shell fixedly connected to the upper surface of the relay protection pressure plate body, a fixed shell slidably connected to the inner wall of the sealing shell, and a rotating shell fixedly connected to the other end of the fixed shell. The rotating shell is sleeved on the upper surface of the relay protection pressure plate body, and the lower surface of the rotating shell is rotatably connected to the upper surface of the relay protection pressure plate body. A sealing plate is slidably connected to the outer surface of the sealing shell, and a fixing rod is fixedly connected to the outer surface of the sealing plate. The limiting mechanism includes a fixing cylinder fixedly connected to the upper surface of the sealing shell, a limiting block slidably connected to the inner wall of the fixing cylinder, and a pulling rod fixedly connected to the upper surface of the limiting block.

[0008] Furthermore, the outer surface of the sealing shell is provided with multiple sets of limiting grooves, the limiting grooves adopt a convex shape structure, and the inner side of the limiting grooves is slidably connected to the outer surface of the sealing plate.

[0009] By adopting the above technical solution, the limiting groove facilitates the limiting of the sealing plate, allowing the sealing plate to slide along the outer surface of the sealing shell, thereby facilitating the sealing of the outer surface of the sealing shell.

[0010] Furthermore, a connecting arm is fixedly connected to the inner wall of the fixed housing, one end of the connecting arm is rotatably connected to the outer surface of the connector body, and the outer surface of the fixed housing is provided with an arc-shaped chamfer.

[0011] By adopting the above technical solution, the arc-shaped chamfer on the outer surface of the fixed shell prevents the fixed shell from getting stuck.

[0012] Furthermore, a spring is fixedly connected to the upper surface of the limiting block, and the upper end of the spring is fixedly connected to the inner wall of the fixed cylinder.

[0013] By adopting the above technical solution, the spring facilitates the reset of the pull rod and the limiting block, and the limiting block adopts a conical structure, which facilitates the limiting of the connecting arm and can prevent the connecting arm from moving to the outer surface of the connector body.

[0014] Furthermore, the outer surface of the rotating housing is slidably connected with a bolt, the outer surface of the bolt is threadedly connected to the upper surface of the connector body, and the outer surface of the bolt is slidably connected with multiple sets of washers.

[0015] By adopting the above technical solution, the bolt is rotated so that it moves downward along the threaded hole on the outer surface of the connector body, thereby facilitating the limiting of the rotating outer shell.

[0016] Furthermore, a retaining ring is provided between the gaskets, and the retaining ring is sleeved on the outer surface of the bolt.

[0017] By adopting the above technical solution, by rotating the bolt, the outer surface of the bolt's outer surface gasket is pressed against the outer surface of the snap ring, which increases the friction between the snap ring and the rotating housing, thereby facilitating the limiting of the rotating housing and preventing the connecting arm and the connector body from separating.

[0018] Beneficial effects

[0019] This utility model provides a relay protection pressure plate device. Compared with the prior art, it has the following advantages:

[0021] 2. This relay protection pressure plate device can limit the connection arm when the circuit is disconnected by a limit block. The bolts, washers and snap rings work together to increase the friction of the rotating shell, doubly reinforcing the connection and preventing the connection arm from separating from the connector body.

[0029] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] Reference Figures 1 to 4 This application provides a relay protection pressure plate device, including a relay protection pressure plate body 1. Two sets of connector bodies 4 are fixedly connected to the upper surface of the relay protection pressure plate body 1, and a sealing mechanism 2 is fixedly connected to the upper surface of the relay protection pressure plate body 1. A limit mechanism 3 is fixedly connected to the outer surface of the sealing mechanism 2. The sealing mechanism 2 includes a sealing shell 206 fixedly connected to the upper surface of the relay protection pressure plate body 1. A fixed shell 202 is slidably connected to the inner wall of the sealing shell 206. A rotating shell 201 is fixedly connected to the other end of the fixed shell 202. The rotating shell 201 is sleeved on the upper surface of the relay protection pressure plate body 1, and the lower surface of the rotating shell 201 is rotatably connected to the upper surface of the relay protection pressure plate body 1. A sealing plate 204 is slidably connected to the outer surface of the sealing shell 206, and a fixing rod 205 is fixedly connected to the outer surface of the sealing plate 204.

[0031] Furthermore, the outer surface of the sealing shell 206 is provided with multiple sets of limiting grooves 203. The limiting grooves 203 adopt a convex structure. The inner side of the limiting grooves 203 is slidably connected to the outer surface of the sealing plate 204. The inner wall of the fixed shell 202 is fixedly connected with a connecting arm 207. One end of the connecting arm 207 is rotatably connected to the outer surface of the connector body 4. The outer surface of the fixed shell 202 is provided with an arc-shaped chamfer.

[0032] In this embodiment, the multi-layered outer shell structure of the sealing mechanism 2 and the sliding sealing plate 204 work together to effectively block the intrusion of external factors such as dust and moisture, protect the internal components, and the arc-shaped chamfer design of the fixed outer shell 202 eliminates the risk of jamming, ensures smooth sealing operation, and improves the efficiency of circuit adjustment.

[0033] Reference Figures 1 to 4 In one aspect of this embodiment, the limiting mechanism 3 includes a fixed cylinder 305 fixedly connected to the upper surface of the sealed housing 206, a limiting block 306 slidably connected to the inner wall of the fixed cylinder 305, and a pull rod 301 fixedly connected to the upper surface of the limiting block 306.

[0034] Furthermore, a spring 307 is fixedly connected to the upper surface of the limiting block 306, and the upper end of the spring 307 is fixedly connected to the inner wall of the fixed cylinder 305. A bolt 302 is slidably connected to the outer surface of the rotating outer shell 201. The outer surface of the bolt 302 is threadedly connected to the upper surface of the connector body 4, and multiple sets of washers 303 are slidably connected to the outer surface of the bolt 302. A retaining spring 304 is provided between the washers 303, and the retaining spring 304 is sleeved on the outer surface of the bolt 302.

[0035] In this embodiment, the limiting block 306 can limit the connecting arm 207 when the circuit is disconnected. The bolt 302, the washer 303 and the snap ring 304 work together to increase the friction of the rotating housing 201, doubly reinforcing the connection and preventing the connecting arm 207 from separating from the connector body 4.

[0036] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0037] Working principle: In terms of circuit connection, one end of the connecting arm 207 in the device is rotatably connected to the connector body 4. When it is necessary to connect the circuit, the connecting arm 207 can be operated to drive the relevant components to achieve circuit connection. When it is necessary to disconnect the circuit, the connecting arm 207 is rotated to cut off the circuit connection, thereby achieving effective control of circuit on / off. When disconnecting the circuit, rotating the outer shell 201 causes the fixed outer shell 202 and the connecting arm 207 to rotate, so that the outer surface of the connecting arm 207 presses against the outer surface of the limiting block 306, causing the limiting block 306 to move upward, so that the limiting block 306 can limit the connecting arm 207 and prevent the connecting arm 207 from sticking to the connector body 4. When connecting the connector body 4 to the circuit, pulling the pulling rod 301... Pull rod 301 moves upward, contacting the limiting position of connecting arm 207. Then rotate fixed housing 202 and rotating housing 201. Before moving fixed housing 202, fixed rod 205 needs to be pulled. The movement of fixed rod 205 causes sealing plate 204 to move upward, so that the outer surface of connecting arm 207 and outer surface of connector body 4 are in contact. By the contact between the outer surface of fixed housing 202 and inner wall of sealing housing 206, it is easy to seal connecting arm 207 and connector body 4. At the same time, bolt 302 can be rotated. The outer surface of bolt 302 and outer surface of gasket 303 are pressed against outer surface of snap ring 304, which increases friction between snap ring 304 and rotating housing 201, thereby limiting rotating housing 201 and preventing connecting arm 207 and connector body 4 from separating.
