Description

Technical Field

[0001] This utility model relates to the field of power tool technology, specifically a quick-connect multi-functional insulating rod. Background Technology

[0002] Insulating rods are a common safety tool in the power industry. Their length is determined by the voltage level; the higher the voltage level, the longer the rod. To facilitate storage and transport, each section of the insulating rod is generally no more than two meters long. Two or more insulating rods are connected to extend the rod, depending on the voltage level of the application location. A common technique involves attaching a threaded metal tube to one end of the insulating rod and a threaded metal tube to the other end, with the two rods directly connected by threads to achieve the desired length.

[0003] When connecting and extending two or more insulating rods, since the internal and external threads are fixed to the ends of the insulating rods, the two insulating rods need to be kept in a straight line, the internal and external threads aligned, and then the insulating rods rotated until tightened. If the insulating rods are long, the weight will inevitably increase, and it will be difficult for one person to align the internal and external threads with one hand. Not only is it difficult to tighten, but in severe cases, it can damage the threads and prevent the insulating rods from being connected. Moreover, if the threads at the connection point become loose during use, the entire insulating rod will wobble, making it difficult to use. Furthermore, if the insulating rod is rotated counterclockwise (such as when removing the grounding wire), one of the insulating rods may come loose. Utility Model Content

[0004] The purpose of this invention is to provide a quick-connect, multi-functional insulating rod to solve the problems mentioned in the background art, such as the inconvenience, time-consuming and labor-intensive nature of direct threaded connection between existing insulating rods.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-connect multi-functional insulating rod, comprising an insulating rod and a handle. The upper and lower ends of the insulating rod are respectively fixed with a female head and a male head by rivets. The male head has an external thread, and a knurled union nut is movably fitted onto the female head. The external thread of the male head matches the thread structure of the knurled union nut on the female head. Multiple insulating rods are connected at their ends to the external thread of the male head by rotating the knurled union nut movably fitted onto the female head. The handle is fixed at its upper end with a female head connected to the male head on the last insulating rod by rivets.

[0006] Preferably, the male insertion part is a conical head, and the female head has a conical hole inside that matches the structure of the conical head.

[0007] Preferably, the lower end of the conical head is provided with a hexagonal head, and the lower end of the conical hole is provided with a hexagonal hole that matches the structure of the hexagonal head.

[0008] Preferably, the upper end face of the female head is provided with a flange that cooperates with the retaining ring provided at the bottom of the knurled union nut to lock the male head.

[0009] Preferably, the outward protruding portion of the rivet blocks the knurled fitting nut.

[0010] Preferably, the female end of the uppermost insulating rod is connected to the male end of the lower part of the power tool.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The quick-connect multi-functional insulating rod has a male head and a female head at its upper and lower ends, respectively. The knurled nut on the outside of the female head of one end of the insulating rod is movably fitted to the external thread on the outside of the male head of the other insulating rod, so that the insulating rod reaches the working length. When extending the insulating rod, there is no need to rotate the insulating rod. You only need to rotate the knurled nut on the outside of the female head to connect. The use of the quick-connect connection method makes the connection of the insulating rod time-saving, labor-saving and not easy to damage. The male and female ends of this quick-connect multi-functional insulating rod are respectively equipped with a tapered head and a tapered hole. During connection, the tapered head on the male end is inserted into the tapered hole on the female end, so that the external threads on the male end of the two insulating rods are naturally aligned with the knurled union nut on the female end. This not only allows the knurled union nut to be tightened easily, but also ensures that there is no gap at the connection between the two insulating rods, so that there will be no shaking, thus strengthening the connection strength. In addition, a hexagonal head is provided at the lower end of the tapered head, and a hexagonal hole is provided at the lower end of the tapered hole to match the structure of the hexagonal head. When the tapered head is inserted into the tapered hole, the hexagonal head is also inserted into the hexagonal hole at the same time, preventing the insulating rod from loosening when it is rotated counterclockwise.

[0020] Please see Figure 1-6This utility model provides a technical solution: a quick-connect multi-functional insulating rod, including an insulating rod 1 and a handle 4. The upper and lower ends of the insulating rod 1 are respectively fixed with a female head 3 and a male head 2 by rivets 5. The male head 2 has an external thread 21, and a knurled union nut 31 is movably fitted onto the female head 3. A flange 33 is provided on the upper end face of the female head 3, and a retaining ring 35 is provided at the bottom end of the knurled union nut 31. The flange 33 on the female head 3 can block the retaining ring 35 at the bottom end of the knurled union nut 31, ensuring the knurled union nut 31 and the external thread 21 on the male head 2 can move freely together. While connecting, it also prevents the knurled union nut 31 from falling off the top of the female head 3. The rivet 5, besides fixing the female head 3 and male head 2 to the upper and lower ends of the insulating rod 1, also protrudes to block the retaining ring 35 at the lower end of the knurled union nut 31, preventing it from falling off the bottom of the female head 3. The external thread 21 of the male head 2 matches the thread structure of the knurled union nut 31 on the female head 3. Multiple insulating rods 1 are connected at both ends by rotating the knurled union nut 31, which is movably fitted on the female head 3, to the external thread 21 of the male head 2, thus extending the overall length. The insertion part of the male head 2 is... The conical head 22 and the female head 3 have a conical hole 32 inside that matches the structure of the conical head 22. When connecting multiple insulating rods 1, the conical head 22 at the bottom of the male head 2 is inserted into the conical hole 32 inside the female head 3, so that the external threads 21 on the male head 2 of the two insulating rods 1 are naturally aligned with the knurled union nut 31 on the female head 3. This not only allows the knurled union nut 31 to be easily tightened, but also strengthens the connection, ensuring that there is no gap at the connection between the two insulating rods 1 and preventing wobbling. A handle 4 is provided at the bottom of the last insulating rod 1, and the upper end of the handle 4 also has A female head 3 is fixedly installed by rivets 5, and the female head 3 is connected to the male head 2 on the insulating rod 1 for easy gripping. In addition, a hexagonal head 23 is provided at the lower end of the conical head 22, and a hexagonal hole 34 is provided at the lower end of the conical hole 32 to match the structure of the hexagonal head 23. When the conical head 22 is inserted into the conical hole 32, the hexagonal head 23 is also inserted into the hexagonal hole 34 at the same time, preventing the insulating rod 1 from loosening when rotated counterclockwise. The uppermost female head 3 of the insulating rod 1 can be connected to the lower male head 2 of power tools (such as grounding wires, switch rods, high voltage detectors, etc.) for use, achieving a multi-purpose function of one rod.

[0021] Working principle: When using this quick-connect multi-functional insulating rod, if two or more insulating rods 1 need to be connected, insert the tapered head 22 on the male end 2 of one insulating rod 1 into the tapered hole 32 on the female end 3 of the other insulating rod 1. Then, turn the knurled nut 31 to connect and tighten it with the external thread 21 on the outside of the male end 2. After reaching the working length, connect the handle 4 to the lower end of the last insulating rod 1 in the same way for gripping. Connect the required tools (such as grounding wire, switch rod, high voltage detector, etc.) to the top insulating rod 1 in the same way before use. After the work is finished, turn the knurled nut 31 counterclockwise to disengage the female end 3 from the male end 2 to disassemble the insulating rod 1 for storage, handling and handling.
