Description

Technical Field

[0001] This utility model relates to the field of pressure plate operating handle technology, and in particular to a relay pressure plate operating handle with an anti-accidental contact structure. Background Technology

[0002] Relay plates are rigid connecting pieces in power protection systems, used to manually connect or disconnect critical circuits such as tripping and signaling circuits of relay protection devices. Their operation requires direct contact with metal components, and the densely packed plates often carry operating voltage, posing a significant safety hazard. Therefore, a design to prevent accidental contact is crucial. Thus, a relay plate operating handle with an anti-accidental contact structure is required when operating the relay plate.

[0003] The existing operation steps for the relay pressure plate are as follows: the operator rotates the knobs at both ends of the pressure plate so that the bottom end of the pressure plate can rotate and the top end of the pressure plate can disengage from the mating knob. Then the operator manually moves the lever on the pressure plate to adjust the position of the pressure plate. Because relay pressure plates are usually installed close together, there is a risk that workers may accidentally touch the pressure plates with their fingers when operating them. Furthermore, because the operating voltage of the pressure plates is relatively high, there are certain safety hazards when workers directly operate the relay pressure plates manually. Utility Model Content

[0004] Therefore, it is necessary to provide a relay control handle with an anti-accidental contact structure to address the safety hazards associated with manually operating the relay control plate.

[0005] A relay pressure plate operating handle with an anti-accidental touch structure includes: a grip rod, on both sides of which are provided multiple positioning blocks; The operating mechanism includes docking components disposed at the top and middle of the grip rod, a plurality of positioning blocks respectively disposed on both sides of the grip rod, and a driving component disposed between two of the docking components.

[0006] In one embodiment, the docking assembly includes a housing embedded in the inner wall of the grip rod, and a snap-fit ​​block is slidably connected inside the housing. The inner wall of the snap-fit ​​block is provided with textures that cooperate with the pressure plate knob.

[0007] In one embodiment, a connecting block is fixedly connected to the back of the snap-fit ​​block, and an adjustment knob is fixedly connected to the end of the connecting block away from the snap-fit ​​block through the outer shell.

[0008] In one embodiment, a limiting block is provided inside the connecting block, and the limiting block is rotatably connected to the inner wall of the snap-fit ​​block.

[0009] In one embodiment, a turntable is rotatably connected to the back of the snap-fit ​​block, and a spring is fixedly connected between the turntable and the limiting block.

[0010] In one embodiment, the drive assembly includes a slide rail embedded in the grip bar, the slide rail being arc-shaped.

[0011] In one embodiment, a ball bearing is slidably connected to the inner wall of the slide rail, and a mating block is fixedly connected to one end of the ball bearing, the mating block being disposed on the outer side of the slide rail.

[0012] In one embodiment, a drive rod is fixedly connected to the end of the ball away from the mating block. The drive rod passes through the gripping rod, and the inner wall of the gripping rod has a groove that mates with the slide rail. Beneficial effects

[0013] 1. By setting up a grip lever and designing a drive component in the middle of the grip lever that can connect with the pressure plate lever, the operator can use the grip lever in conjunction with the drive lever to move the lever when operating the pressure plate, which reduces the probability of the operator's fingers directly contacting the pressure plate, effectively reducing the risk of accidental contact with the pressure plate, and avoiding electric shock or other safety hazards caused by accidental contact with fingers. 2. By embedding a docking component on the inner wall of the grip, operators can more easily and quickly dock the handle with the knob of the pressure plate, reducing docking difficulty, reducing operator time, and thus improving work efficiency.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] The following is combined with Figure 1 - Figure 5 This invention describes a relay pressure plate operating handle with an anti-accidental-touch structure.

[0019] In one embodiment, a relay pressure plate operating handle with an anti-accidental touch structure includes: a grip rod 100, and multiple positioning blocks 200 are provided on both sides of the grip rod 100; The operating mechanism 300 includes docking components 310 disposed at the top and middle of the grip rod 100, multiple positioning blocks 200 disposed on both sides of the grip rod 100, and a drive component 320 disposed between two docking components 310.

[0020] Before using this device to adjust the pressure plate, it is necessary to ensure that there are four positioning posts around the pressure plate that cooperate with the positioning block 200. At the same time, a columnar protrusion is set on the lever in the middle part of the pressure plate. This protrusion needs to cooperate with the docking block 322. The inner wall texture of the snap-fit ​​block 312 needs to be matched with the texture of the pressure plate knob surface.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the docking assembly 310 includes a housing 311 embedded in the inner wall of the gripping rod 100. A locking block 312 is slidably connected inside the housing 311, and the inner wall of the locking block 312 has textured surfaces that engage with the pressure plate knob. A connecting block 3121 is fixedly connected to the back of the locking block 312. One end of the connecting block 3121, away from the locking block 312, extends through the housing 311 and is fixedly connected to an adjusting knob 3122. A limiting block 3111 is provided inside the connecting block 3121 and is rotatably connected to the inner wall of the locking block 312. A turntable 3112 is rotatably connected to the back of the locking block 312, and a spring 3113 is fixedly connected between the turntable 3112 and the limiting block 3111.

[0022] In this embodiment, the outer shell 311 is respectively disposed at the top and middle of the grip rod 100. The locking block 312 slides through a limiting ring disposed on its outer surface and a limiting groove disposed inside the outer shell 311. When the locking block 312 is pushed, the locking block 312 slides in the limiting groove through the limiting ring on its surface and compresses the spring 3113. At the same time, the surface of the limiting block 3111 is provided with multiple arc-shaped blocks, and the end of the outer shell 311 is provided with an annular groove that mates with the arc-shaped blocks. Multiple arc-shaped blocks are disposed in the annular groove, and the limiting block 3111 is rotatably connected to the outer shell 311 through the cooperation of the arc-shaped blocks and the annular groove. The surface of the connecting block 3121 is provided with multiple arc-shaped openings that are adapted to the size of the arc-shaped blocks. When the locking block 312 is pushed, The locking block 312 drives the connecting block 3121 and the adjusting knob 3122 to move synchronously. At this time, the arc-shaped block on the surface of the limiting block 3111 will slide in the arc-shaped opening of the connecting block 3121, so that the locking block 312 can slide normally. When the adjusting knob 3122 is rotated, the adjusting knob 3122 drives the connecting block 3121 to rotate the locking block 312. At this time, the locking block 312 drives the arc-shaped block to rotate in the annular groove through the arc-shaped opening. When the locking block 312 rotates until the texture of its inner wall coincides with the texture of the pressure plate knob surface, the spring 3113 will push the turntable 3112 to drive the locking block 312 to insert into the pressure plate knob. At this time, by continuing to rotate the adjusting knob 3122, the locking block 312 and the pressure plate knob will rotate as a whole, so that the adjusting knob 3122 will be loosened. It should be noted that the relay pressure plate is usually installed on the surface of the electrical cabinet and consists of a pressure plate body, a base terminal, and a locking mechanism. The pressure plate body is a metal conductive sheet with a lever in the middle and a cylindrical protrusion in the middle of the lever. The base terminal consists of two copper alloy contacts that are connected to the top and bottom of the metal conductive sheet, respectively. The bottom of the pressure plate body is rotatably connected to the copper alloy contacts, and the top of the pressure plate body is inserted into the copper alloy contacts. A locking mechanism is provided between the copper alloy contacts and the pressure plate body. The locking mechanism is usually a spiral pressure block, which is driven by the pressure plate knob. This device connects to the pressure plate knob and lever and drives them, thereby avoiding the operator's direct contact with the lever to operate the pressure plate, reducing the safety accidents caused by accidental activation of the lever.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the drive assembly 320 includes a slide rail 321 embedded in the grip rod 100, and the slide rail 321 is arc-shaped. A ball bearing 323 is slidably connected to the inner wall of the slide rail 321, and a mating block 322 is fixedly connected to one end of the ball bearing 323. The mating block 322 is located on the outer side of the slide rail 321. A drive rod 324 is fixedly connected to the end of the ball bearing 323 away from the mating block 322. The drive rod 324 passes through the grip rod 100, and a groove that mates with the slide rail 321 is formed on the inner wall of the grip rod 100.

[0024] In this embodiment, the slide rail 321 is recessed and cooperates with the ball 323, so that the ball 323 can slide stably in the slide rail 321 without becoming loose in the slide rail 321. The drive rod 324 consists of a drive pad and a crossbar disposed between the drive pad and the ball 323. The drive pad is disposed on the surface of the grip rod 100, and the crossbar is disposed inside the grip rod 100. The grip rod 100 has a groove for the drive rod 324 to move inside.

[0025] Working principle: Multiple positioning blocks 200 in this device are inserted by aligning them with the positioning rods on the surface of the electrical cabinet. At this time, the locking block 312 will align with the knob of the pressure plate. As the handle slides along the positioning rods, the knob of the pressure plate will correspondingly enter the two outer shells 311. If the texture on the surface of the knob happens to coincide with the texture of the locking block 312, then the knob of the pressure plate will directly insert into the locking block 312. At this point, the connecting block 3121 can be rotated by turning the adjusting knob 3122, and the connecting block 3121 will drive the locking block 3121 to rotate. 2. Rotating the knob of the pressure plate will cause it to rotate, loosening the pressure plate. At the same time, the cylindrical protrusion in the center of the lever in the middle of the pressure plate will be inserted into the docking block 322. Then, the operator directly moves the drive rod 324, which drives the ball 323 to slide along the slide rail 321. The drive rod 324 slides in the groove inside the grip rod 100, causing the docking block 322 to slide. The docking block 322 drives the lever of the pressure plate to move, thereby causing the pressure plate to rotate and separating the top of the pressure plate from the corresponding knob to complete the operation. If the texture on the surface of the pressure plate knob does not match the texture on the inner wall of the mating block 322 when the pressure plate knob is inserted into the outer casing 311, the pressure plate knob will push the locking block 312, pushing the locking block 312 into the grip rod 100. At this time, the locking block 312 will slide along the inside of the outer casing 311. When the handle moves to the preset position, by rotating the adjustment knob 3122, the adjustment knob 3122 will drive the locking block 312 to rotate, so that the inner wall of the locking block 312 coincides with the knob surface of the pressure plate, completing the mating. The above operation can be performed.

[0026] It should be noted that the spring 3113 and the adjusting knob 3122 mentioned above are both devices with relatively mature existing technology. The specific models can be selected according to actual needs, and will not be elaborated here.

[0027] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
