Description

Technical Field

[0001] This invention relates to the field of power operation tools, specifically to a quick-locking structure for an insulated operating rod. Background Technology

[0002] Insulated operating rods are one of the most commonly used safety tools for power supply workers. They are mainly used to perform power outage and restoration operations on distribution transformers and line switches, using the insulated rod to isolate high-voltage electricity and ensure the personal safety of workers.

[0003] Most current insulated operating rods consist of a handheld rod and a working rod locked together by threads. While these rods can help power workers operate transformers and line switches to cut off and restore power, they pose a risk of the rod rotating and detaching during use. Furthermore, power workers need to assemble the rod beforehand, and when adjusting the length of the insulated operating rod, they often have to place it on the ground and reassemble the working rod to the corresponding length, which is inconvenient. Therefore, we propose a quick-locking structure for insulated operating rods. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a quick-locking structure for an insulating operating rod.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a quick-locking structure for an insulating operating rod, comprising a handheld rod, a connecting rod slidably inserted inside the handheld rod and threaded on its outer side, a working rod threaded onto one end of the connecting rod, and a working part fixedly sleeved on the working rod away from the handheld rod. The structure includes an adjustment component, comprising a limiting block fixed to the end of the connecting rod away from the working rod and abutting against the end of the handheld rod for rotating the connecting rod, and an operating part fixed to the side of the limiting block away from the connecting rod for rotating the limiting block. A locking component includes receiving grooves on both sides of the operating part and insert rods disposed inside the receiving grooves for preventing the connecting rod from rotating. The handheld rod near the limiting block has multiple insertion holes that slide with the insert rods. Through the operation of these components, power workers can perform power outage and power-on / off operations on distribution transformers and line switches, lock the insulating operating rod, and facilitate the adjustment of the length of the insulating operating rod when lifting it.

[0006] Furthermore, the actuating assembly includes a connecting groove formed at the end of the operating section away from the limiting block, a connecting block slidably inserted into the connecting groove, and an actuating block fixed at the end of the connecting block located outside the connecting groove. One end of the insert rod is slidably inserted into an adjacent insertion hole, and the end of the insert rod away from the insertion hole is fixed to the actuating block. A spring is fixed at the end of the connecting block located inside the connecting groove, with its tail end fixed to the inner wall of the end of the connecting groove for driving the actuating block to perform a reset displacement. Through the elasticity of the spring, the connecting block, the actuating block, and the insert rod are pulled to perform a reset displacement.

[0007] Furthermore, the insertion hole is circumferentially opened at the end of the connecting rod with the midpoint of the connecting rod as the center, and the limiting block has multiple through holes that slide with the insertion rod. Through the through holes, the limiting block can be prevented from interfering with the displacement of the insertion rod.

[0008] Furthermore, the connecting groove is a rectangular block, and the connecting block is a rectangular block. By using connecting grooves and connecting blocks, which are both rectangular structures, the connecting block can be prevented from rotating inside the connecting groove.

[0009] Furthermore, the limiting block has a connecting ring movably sleeved on the outside of the hand handle on the side away from the operating part. The inner wall of the connecting ring has an annular groove, and multiple fixing blocks fixed on the hand handle are slidably connected inside the annular groove. The limiting block has multiple mounting holes, and a screw with one end fixed on the connecting ring is slidably inserted into the mounting hole. The outer wall of the other end of the screw is threaded with a nut that abuts against the limiting block and has a diameter larger than the mounting hole diameter. Through the operation of the above components, the insulated operating rod can be easily disassembled by power workers.

[0010] Furthermore, the handheld lever has multiple loading slots at one end near the working lever. A loading rod fixed to the end of the working lever is slidably inserted into the loading slot. Through the cooperation of the loading rod and the loading slot, the handheld lever and the working lever can be connected to prevent the working lever from detaching from the handheld lever at will.

[0011] Furthermore, the support assembly includes support parts disposed on both sides of the handheld rod for supporting the handheld rod, a sliding groove opened inside the support parts, and a sliding block sliding inside the sliding groove. The side of the sliding block near the handheld rod is rotatably connected to a connecting shaft whose tail end is fixed on the handheld rod. The side of the actuating block away from the handheld rod is provided with an assembly block located between the two support parts. The end of the support part near the assembly block is provided with a transition hole. A bolt threaded to the assembly block is slidably inserted into the transition hole. Through the operation of the above components, it is convenient for power workers to lift the insulated operating rod, convenient for power workers to adjust the corresponding position of the lifted insulated operating rod, and convenient for power workers to carry the insulated operating rod to climb power equipment.

[0012] Furthermore, the nut of the first bolt is larger than the diameter of the adapter hole. By using a nut larger than the diameter of the adapter hole, the support part can be prevented from separating from the first bolt through the adapter hole.

[0013] Furthermore, connecting straps are fixed on both sides of the assembly block, and a buckle is fixed at the end of the connecting strap on one side of the assembly block to engage with the connecting strap on the other side of the assembly block. Through the cooperation of the connecting straps and the buckles, it is convenient for power workers to fix the assembly block to their bodies.

[0014] Furthermore, a threaded hole is provided on the support part located on one side of the hand handle. The internal thread of the threaded hole is threaded through a bolt two for locking the support part on the hand handle. The support part can be limited to the outside of the hand handle by the bolt two.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention can lock the insulating operating rod, preventing it from rotating and falling off during use, thus ensuring high safety. It also allows power workers to easily adjust the length of the insulating operating rod when lifting it, eliminating the need to place it on the ground for length adjustment. This results in high performance. Furthermore, the insulating operating rod can be easily disassembled for convenient carrying and transportation, making it convenient to use.

[0016] 2. This invention allows power workers to easily lift the insulated operating rod, saving manpower. It also allows power workers to easily adjust the position of the lifted insulated operating rod and carry it to climb power equipment. It has a wide range of applications.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1: Combination Figure 1 , Figure 2 , Figure 5 and Figure 9This embodiment of an insulating operating rod quick-locking structure includes a handheld rod 1, a connecting rod 2 slidably inserted inside the handheld rod 1 and threaded on its outer side, a working rod 3 threadedly sleeved on one end of the connecting rod 2, and a working part 4 fixedly sleeved on the end of the working rod 3 away from the handheld rod 1. It includes: an adjustment assembly comprising a limiting block 5 fixed to the end of the connecting rod 2 away from the working rod 3 and abutting against the end of the handheld rod 1 for rotating the connecting rod 2, and an operating part 15 fixed to the side of the limiting block 5 away from the connecting rod 2 for rotating the limiting block 5; and a locking assembly comprising receiving grooves 20 on both sides of the operating part 15 and insert rods 21 disposed inside the receiving grooves 20 for preventing the connecting rod 2 from rotating. The handheld rod 1 near the limiting block 5 has multiple insertion holes that slidably engage with the insert rods 21. The handheld rod 1 near the working rod 3 has multiple loading grooves 6, and loading rods 7 fixed to the end of the working rod 3 are slidably inserted into the loading grooves 6.

[0021] The implementation principle of the quick-locking structure of the insulating operating rod in this embodiment is as follows: The insulating operating rod, composed of a handheld rod 1, a connecting rod 2, a working rod 3, and a working part 4, can help power workers perform power-on and power-off operations on distribution transformers and line switches. When power workers need to adjust the total length of the insulating operating rod during use, they can pull the insertion rod 21 to disengage it from the adjacent insertion hole. Then, they can rotate the operating part 15 to rotate the connecting rod 2. Through the cooperation of the connecting rod 2 and the working rod 3, and through the cooperation of the loading groove 6 and the loading rod 7, the connecting rod 2 is displaced, and the working part 4 is displaced. At this time, the total length of the insulating operating rod can be adjusted. After the total length of the insulating operating rod is adjusted, the insertion rod 21 can be pushed to insert it into the adjacent insertion hole. At this time, the operating part 15 is locked, the connecting rod 2 is locked, and the length of the insulating operating rod is locked, allowing power workers to conveniently use the insulating operating rod.

[0022] Example 2: Combination Figure 10This embodiment is further improved on the basis of embodiment 1 in that: the toggle assembly includes a connecting groove 16 opened at the end of the operating part 15 away from the limiting block 5, a connecting block 17 slidably inserted into the connecting groove 16, and a toggle block 18 fixed at the end of the connecting block 17 located outside the connecting groove 16. One end of the insertion rod 21 is slidably inserted into the adjacent insertion hole, and the end of the insertion rod 21 away from the insertion hole is fixed to the toggle block 18. The end of the connecting block 17 located inside the connecting groove 16 is fixed with a spring 19 whose tail end is fixed to the inner wall of the end of the connecting groove 16 for driving the toggle block 18 to perform reset displacement. By pulling the toggle block 18, the insertion rod 21 can be moved to move and move the insertion rod 21 away from the adjacent insertion hole. After the total length of the insulating operating rod is adjusted, the toggle block 18 can be loosened. Through the elasticity of the spring 19, the connecting block 17, the toggle block 18 and the insertion rod 21 are pulled to perform reset displacement and drive the insertion rod 21 to insert into the adjacent insertion hole.

[0023] The insertion hole is opened circumferentially at the end of the connecting rod 2 with the midpoint of the connecting rod 2 as the center. The limiting block 5 has multiple through holes that slide with the insertion rod 21. Through the through holes, the limiting block 5 can be prevented from interfering with the displacement of the insertion rod 21.

[0024] The connecting groove 16 is a rectangular block, and the connecting block 17 is a rectangular block. By using the connecting groove 16 and the connecting block 17, which are both rectangular structures, the rotation of the connecting block 17 inside the connecting groove 16 can be prevented.

[0025] Example 3: Combination Figure 3 and Figure 7This embodiment, based on embodiment 1, further improves upon the following: A connecting ring 8 is provided on the side of the limiting block 5 away from the operating part 15, movably sleeved on the outside of the handheld rod 1. An annular groove is formed on the inner wall of the connecting ring 8, and multiple fixing blocks 9 fixed to the handheld rod 1 are slidably connected inside the annular groove. Multiple mounting holes are formed on the limiting block 5, and a screw 10, one end of which is fixed to the connecting ring 8, is slidably inserted into the mounting holes. A nut 14, with a diameter larger than the mounting hole diameter and abutting against the limiting block 5, is threaded onto the outer wall of the other end of the screw 10. The connecting ring 8 can limit the limiting block 5 to the outside of the handheld rod 1. When it is necessary to disassemble the insulated operating rod, the actuating block 18 can be pulled, which can move the insertion rod 21. The movement causes the insertion rod 21 to disengage from the adjacent insertion hole. Then, the operating part 15 is rotated, causing the connecting rod 2 to rotate. Through the cooperation of the connecting rod 2 and the working rod 3, and through the cooperation of the loading groove 6 and the loading rod 7, the connecting rod 2 is displaced, causing the working part 4 to displace. After the displaced connecting rod 2 separates from the connecting rod 1, the nut 14 can be rotated, causing the nut 14 to displace. After the nut 14 separates from the screw 10, the operating part 15 can be pulled, causing the limiting block 5 to displace, causing the connecting rod 2 to displace. When the connecting rod 2 disengages from the inside of the handheld rod 1, the handheld rod 1, the connecting rod 2, and the working rod 3 are separated, thus facilitating the carrying and transportation of the insulating operating rod by power workers.

[0026] Example 4: Combination Figure 4 , Figure 6 and Figure 8This embodiment, based on embodiment 2, further improves upon the following: the support assembly includes support portions 22 on both sides of the handheld lever 1 for supporting the handheld lever 1, a sliding groove 25 opened inside the support portion 22, and a sliding block 24 sliding inside the sliding groove 25. A connecting shaft 23, with its tail fixed to the handheld lever 1, is rotatably connected to the side of the sliding block 24 closest to the handheld lever 1. An assembly block 11 is located between the two support portions 22 on the side of the actuating block 18 away from the handheld lever 1. A transition hole is opened at the end of the support portion 22 closest to the assembly block 11, and a bolt 27 threadedly connected to the assembly block 11 is slidably inserted into the transition hole. When an electrician needs to lift the insulating operating lever during use, they can fix the assembly block 11 to their body, rotate the bolt 27 to fix the support portion 22 to the assembly block 11, and then hold the operating portion 15 and press it down. At this time, the sliding block 24 and the connecting shaft 23... The working mechanism, through the cooperation of the support part 22 and the handheld rod 1, causes the handheld rod 1 to deflect, which in turn causes the connecting rod 2, working rod 3, and working part 4 to deflect, thus facilitating the lifting of the insulated operating rod by power workers and saving manpower. Furthermore, through the cooperation of the sliding block 24 and the sliding groove 25, the user can easily adjust the corresponding position of the insulated operating rod between the two support parts 22. When power workers are climbing power equipment, they can rotate bolt 27 to move it. When the support part 22 is no longer in contact with the assembly block 11, the angle of the support part 22 can be adjusted through the cooperation of the adapter hole and bolt 27, so that the support part 22 and the power worker are at the same level, thus facilitating the power worker to carry the insulated operating rod while climbing power equipment. By rotating bolt 27, bolt 27 is separated from the assembly block 11, allowing the support part 22 to be detached from the handheld rod 1, thus facilitating the use of the insulated operating rod by power workers.

[0027] The nut of bolt 27 is larger than the diameter of the adapter hole. By using a nut that is larger than the diameter of the adapter hole, the support part 22 can be prevented from separating from bolt 27 through the adapter hole.

[0028] Both sides of the assembly block 11 are fixed with connecting straps 12. The end of the connecting strap 12 on one side of the assembly block 11 is fixed with a buckle 13 for engaging the connecting strap 12 on the other side of the assembly block 11. Through the cooperation of the connecting strap 12 and the buckle 13, the power workers can easily fix the assembly block 11 to their body.

[0029] The support part 22 located on one side of the handheld lever 1 has a threaded hole. The internal thread of the threaded hole is threaded with a bolt 26 that is threaded onto the handheld lever 1 to lock the support part 22. The bolt 26 can limit the support part 22 to the outside of the handheld lever 1. When the support part 22 needs to be adjusted, the bolt 26 can be rotated to separate the bolt 26 from the handheld lever 1, at which time the support part 22 can be adjusted.

[0030] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
