Description

Technical Field

[0001] This utility model relates to the field of special wrenches, and in particular to special wrenches for shut-off valve switches. Background Technology

[0002] A special-purpose wrench consists of a special-purpose wrench body and a positioning component. It is mainly used for rotating the shut-off valve switch and is a common type of shut-off valve switch in the current technology.

[0003] Existing technologies, such as the utility model patent with publication number CN204505176U, disclose a stop valve wrench. This patent uses a handle, an extension rod, and a clamping part. The extension rod is a cylindrical rod structure with a handle at one end and a clamping part at the other end. The handle is fixedly connected to the extension rod. The clamping part includes a connecting end and a clamping end. The connecting end is a rectangular plate structure with clamping ends at both ends. The clamping end is a "Y"-shaped plate structure and is fixedly connected to the connecting end. In use, the "Y"-shaped clamping end is placed on the stop valve, and the handle is rotated. The extension rod drives the clamping part to rotate, causing the stop valve to rotate and completing the valve opening and closing action.

[0004] The inventors discovered in their daily work that when using a special wrench to rotate a shut-off valve switch, the operator needs to apply a lot of force to rotate the valve switch because the valve switch has a large tightness and the length of the special wrench body is fixed. This not only makes the operation difficult, but also leads to a decrease in the efficiency of the personnel. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that in the existing technology, when using a special wrench to rotate the shut-off valve switch, the valve switch has a large tightness and the length of the special wrench body is fixed, and the operator needs to apply a lot of force to rotate the valve switch. This not only makes the operation difficult, but also reduces the work efficiency of the personnel. Therefore, a special wrench for shut-off valve switches is proposed.

[0006] To solve the above-mentioned technical problems, this utility model provides a special wrench for shut-off valves, comprising: a special wrench body and a replacement structure. A positioning component is fixedly connected to one side of the special wrench body, and an auxiliary structure is provided on one side of the special wrench body. The auxiliary structure includes two fixing plates and several positioning holes. The two fixing plates are fixedly connected to the special wrench body, and the several positioning holes are evenly opened on the special wrench body. A limit groove is opened on the inner wall of the fixing plate, and a moving block is slidably connected to the inner wall of the limit groove. A moving plate is fixedly connected to the side of the two moving blocks that are close to each other. A plug rod is slidably connected to the inner wall of the moving plate. The plug rod is slidably connected to the positioning hole. A spring is sleeved on the arc surface of the plug rod. The two ends of the spring are fixedly connected to the plug rod and the moving plate, respectively. A handle is fixedly connected to the side of the moving plate away from the positioning component, and an anti-slip sleeve is installed on the arc surface of the handle by means of the replacement structure.

[0007] The effect achieved by the above components is that when personnel need to use the special wrench body to rotate the shut-off valve switch, the personnel can first move the insert rod according to the size of the operating space, so that the insert rod slides out of the inner wall of the positioning hole, and then move the moving plate, so that the moving plate moves away from the positioning component, until the moving plate moves to the appropriate position. This can increase the leverage force, reduce the force required by the personnel, and also improve the applicability of the special wrench body.

[0008] Preferably, a limiting rod is fixedly connected to the inner wall of the limiting groove, and the limiting rod is slidably connected to the moving block.

[0009] The effect achieved by the above components is that the limiting rod can limit the movement of the moving block and prevent the moving block from becoming misaligned during the sliding process on the inner wall of the limiting groove.

[0010] Preferably, a pull ring is fixedly connected to the end of the insertion rod away from the positioning hole, and the pull ring has a circular cross-section.

[0011] The effect achieved by the above components is that the pull ring makes it easy for personnel to move the plug, which can improve the ease of operation for personnel.

[0012] Preferably, a guide block is fixedly connected to the end of the insertion rod away from the pull ring.

[0013] The effect achieved by the above components is that the guide block can guide the insertion rod, making it easier for personnel to slide the insertion rod into the inner wall of the positioning hole.

[0014] Preferably, the fixing plate is a stainless steel plate.

[0015] The effect achieved by the above components is that the stainless steel plate has high strength and good wear resistance, which can prevent the fixing plate from deforming during short-term use.

[0016] Preferably, the inner wall of the grip is provided with a replacement structure, which includes two connecting grooves and a positioning plate. Both connecting grooves are formed on the grip, and the positioning plate is fixedly connected to the grip. A connecting block is slidably connected to the inner wall of each connecting groove, and the two connecting blocks are fixedly connected to an anti-slip sleeve. The inner wall of the positioning plate has two connecting grooves, and an adjusting block and a connecting block are slidably connected to the inner wall of each connecting groove. The adjusting block and the connecting block are fixedly connected. A telescopic rod is fixedly connected to the inner wall of each connecting groove, and the output end of the telescopic rod is fixedly connected to the adjusting block. A compression spring is fitted onto the arc surface of the telescopic rod, and both ends of the compression spring are fixedly connected to the adjusting block and the connecting groove, respectively. A stop block is fixedly connected to the side of the connecting block closest to the connecting block, and an auxiliary block is fixedly connected to the side of the adjusting block furthest from the grip.

[0017] The effect achieved by the above components is that when the anti-slip sleeve needs to be replaced after a long period of use, the personnel can move the two auxiliary blocks to move the two abutments closer to each other until the abutments are away from the side of the connecting block. Then the personnel can move the anti-slip sleeve until the connecting block slides out of the inner wall of the connecting groove, which makes it convenient for personnel to replace the anti-slip sleeve and improves the work efficiency of the personnel.

[0018] Preferably, the inner wall of the auxiliary block is provided with a plurality of anti-slip grooves, and the plurality of anti-slip grooves are evenly provided on the auxiliary block.

[0019] The effect achieved by the above components is that the anti-slip groove can increase the friction between the personnel's hands and the auxiliary block, and can prevent the personnel from slipping when moving the auxiliary block.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0032] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0033] Please see Figure 1 The special wrench for shut-off valves provided in this embodiment includes: a special wrench body 1 and a replacement structure 4. A positioning component 2 is fixedly connected to one side of the special wrench body 1, an auxiliary structure 3 is provided on one side of the special wrench body 1, and a replacement structure 4 is provided on the inner wall of the handle 312.

[0034] In the embodiments of this utility model, please refer to Figures 2 to 5 The auxiliary structure 3 includes two fixed plates 301 and several positioning holes 309. The two fixed plates 301 are fixedly connected to the special wrench body 1. Several positioning holes 309 are evenly opened on the special wrench body 1. The inner wall of the fixed plate 301 is provided with a limiting groove 302. The inner wall of the limiting groove 302 is slidably connected to a moving block 303. The side of the two moving blocks 303 that is close to each other is fixedly connected to a moving plate 308. The inner wall of the moving plate 308 is slidably connected to a plug rod 305. The plug rod 305 is slidably connected to the positioning hole 309. The arc surface of the plug rod 305 is fitted with a spring 307. The two ends of the spring 307 are fixedly connected to the plug rod 305 and the moving plate 308 respectively. The side of the moving plate 308 away from the positioning component 2 is fixedly connected to a handle 312. The arc surface of the handle 312 is fitted with an anti-slip sleeve 311 by means of the replacement structure 4. When a person needs to rotate the shut-off valve using the dedicated wrench body 1, they can first move the insert rod 305 according to the size of the operating space, causing the insert rod 305 to slide out of the inner wall of the positioning hole 309, and then move the moving plate 308 away from the positioning component 2 until the moving plate 308 moves to the appropriate position. This increases the leverage force, reduces the force required by the person, and improves the applicability of the dedicated wrench body 1. The inner wall of the limiting groove 302 is fixedly connected to the limiting rod 304, which is slidably connected to the moving block 303. The limiting rod 304 can limit the moving block 303, preventing the moving block 303 from misaligning during sliding on the inner wall of the limiting groove 302. The end of the insert rod 305 away from the positioning hole 309 is fixedly connected to a pull ring 306, which has a circular cross-section. The pull ring 306 facilitates the movement of the insertion rod 305, improving operational convenience. A guide block 310 is fixedly connected to the end of the insertion rod 305 furthest from the pull ring 306. The guide block 310 guides the insertion rod 305, allowing it to slide easily into the inner wall of the positioning hole 309. The fixing plate 301 is made of stainless steel. Stainless steel has high strength and good wear resistance, preventing deformation of the fixing plate 301 during short-term use.

[0035] In the embodiments of this utility model, please refer to Figure 6 and Figure 7The replacement structure 4 includes two connecting grooves 401 and a positioning plate 403. Both connecting grooves 401 are formed on the handle 312. The positioning plate 403 is fixedly connected to the handle 312. Connecting blocks 402 are slidably connected to the inner wall of the connecting grooves 401. The two connecting blocks 402 are fixedly connected to the anti-slip sleeve 311. Two connecting grooves 405 are formed on the inner wall of the positioning plate 403. Adjusting blocks 408 and connecting blocks 411 are slidably connected to the inner wall of the connecting grooves 405. Adjusting blocks 408 and... The connecting block 411 is fixedly connected, and the inner wall of the connecting groove 405 is fixedly connected to the telescopic rod 406. The output end of the telescopic rod 406 is fixedly connected to the adjusting block 408. The arc surface of the telescopic rod 406 is fitted with a compression spring 407. The two ends of the compression spring 407 are fixedly connected to the adjusting block 408 and the connecting groove 405 respectively. The side of the connecting block 411 near the connecting block 402 is fixedly connected to the stop block 404, and the side of the adjusting block 408 away from the handle 312 is fixedly connected to the auxiliary block 409. When the anti-slip sleeve 311 needs to be replaced after prolonged use, personnel can move the two auxiliary blocks 409 to move the two abutment blocks 404 closer together until the abutment blocks 404 are away from the connecting block 402. Then, personnel can move the anti-slip sleeve 311 until the connecting block 402 slides out of the inner wall of the connecting groove 401, thus facilitating the replacement of the anti-slip sleeve 311 and improving work efficiency. The inner wall of the auxiliary block 409 is provided with several anti-slip grooves 410, which are evenly distributed on the auxiliary block 409. The anti-slip grooves 410 increase the friction between the personnel's hands and the auxiliary block 409, preventing slippage during the movement of the auxiliary block 409.

[0036] The working principle of the special wrench for shut-off valves provided by this utility model is as follows: When a person needs to rotate the shut-off valve, the person places the positioning component 2 on the body 1 of the special wrench onto the arc surface of the shut-off valve switch. This positioning component 2 can achieve the purpose of saving the person's strength and increasing efficiency by changing the force point to the rotating wheel of the shut-off valve switch. When a person needs to rotate a tight shut-off valve switch, the person can first use the pull ring 306 to drive the insertion rod 305 to move away from the positioning hole 309. The pull ring 306 facilitates the movement of the insertion rod 305, improving the ease of operation. Then, the insertion rod 305 drives the guide block 310 to move away from the positioning hole 309. The insertion rod 305 also drives the spring 307 to stretch. The guide block 310 guides the insertion rod 305, making it easy for the person to slide the insertion rod 305 into the inner wall of the positioning hole 309. Then, the person moves the moving plate 308, causing the moving plate 308 to move away from the positioning component 2. 308 drives two movable blocks 303, insert rod 305, spring 307, and handle 312 to move away from positioning component 2. The movable blocks 303 slide on the arc surface of the limiting rod 304, which limits the movable blocks 303 and prevents them from misaligning during sliding on the inner wall of the limiting groove 302. Then, the handle 312, with the help of the replacement structure 4, drives the anti-slip sleeve 311 to move away from positioning component 2 until the movable plate 308 moves to the appropriate position. The distance is determined by the distance, and then the person releases the pull ring 306. At this time, the spring 307 rebounds, causing the insertion rod 305 and the guide block 310 to move towards the positioning hole 309 until the guide block 310 and the insertion rod 305 slide into the inner wall of the positioning hole 309. At this time, the person can rotate the anti-slip sleeve 311 to drive the shut-off valve switch to rotate. The fixing plate 301 is made of stainless steel plate. Stainless steel plate has high strength and good wear resistance, which can prevent the fixing plate 301 from deforming during short-term use.

[0037] Additionally, when personnel need to replace the anti-slip sleeve 311, they can first move the two auxiliary blocks 409 closer together. The anti-slip grooves 410 on the inner walls of the auxiliary blocks 409 increase the friction between the personnel's hands and the blocks, preventing slippage during movement. Then, the auxiliary blocks 409 move the adjusting block 408 closer together. The adjusting block 408 then moves the connecting block 411 and the output end of the telescopic rod 406 closer together. The adjusting block 408 also causes the compression spring 407 to retract. Finally, the connecting block 411 moves the abutment block 404 away from the connecting block. The block 402 is moved in the direction until the block 404 is completely away from the side of the connecting block 402. Then the personnel move the anti-slip sleeve 311, so that the anti-slip sleeve 311 moves away from the moving plate 308. The anti-slip sleeve 311 drives the two connecting blocks 402 to move away from the connecting groove 401, until the connecting block 402 completely slides out of the inner wall of the connecting groove 401. Then the personnel move the new anti-slip sleeve 311, so that the anti-slip sleeve 311 slides on the arc surface of the handle 312. Then the inclined surface of the connecting block 402 abuts against the connecting block 411. Then the connecting block 402 drives the connecting block 411 to move in the direction where the two connecting blocks 411 are closer to each other, until the connecting block 402 completely slides into the inner wall of the connecting groove 401.

[0038] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0039] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
