Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage electric equipment, in particular to an insulating rod for testing high-voltage electric equipment. Background Art

[0002] Insulating rod is a unified name for insulating tools specially used in power systems. It can be used for live working, live maintenance and live maintenance work tools. It is mainly made of insulating tubes or insulating rods with end accessories. Generally, live action needs to be performed through insulating rods during the operation and inspection of power equipment. Since the operation is relatively dangerous, the general insulating rods are short and are not used in combination, which requires users to get close to the power equipment, increasing the risk of use. Based on this, an insulating rod for high-voltage power equipment testing is proposed to solve the above problems. Utility Model Content

[0003] The purpose of the utility model is to overcome the shortcomings of the prior art and provide an insulating rod for testing high-voltage power equipment, which effectively solves the deficiencies of the prior art.

[0004] In order to achieve the above-mentioned purpose, an embodiment of the utility model on one hand provides an insulating rod for testing high-voltage power equipment, comprising a first round tube and a second round tube, the first round tube being located on the outer wall of the second round tube, a first mounting seat being arranged at the top end of the first round tube, a second mounting seat being fixedly connected to the bottom end of the first round tube, an inclined surface being arranged in the middle part of the inner wall of the second mounting seat, a conical gasket being arranged inside the second mounting seat, a locking ring being threadedly connected to the bottom end of the inner wall of the second mounting seat, and the top end of the locking ring being fitted with the bottom surface of the conical gasket.

[0005] Preferably, any of the above schemes is that both ends of the inner wall of the first circular tube are fixedly connected to the outer walls of the first mounting seat and the second mounting seat respectively by rivets. By using this scheme, the first mounting seat and the second mounting seat can be stably installed at the two end positions of the first circular tube. At the same time, the rivets are used to prevent relative sliding between the first mounting seat and the second mounting seat and the first circular tube, so that the user can easily rotate the locking ring and the second mounting seat, and the first mounting seat and the fixed plate relative to each other.

[0006] Preferably, any of the above schemes is that a threaded hole is provided in the middle of the first mounting seat, a fixing plate is provided at the top of the first mounting seat, and a clamping tool is fixedly connected to the top of the fixing plate, and a threaded column is fixedly connected to the bottom end of the fixing plate, and the threaded column is threadedly connected to the threaded hole. By using this scheme, it is convenient for the fixing plate to rotate relative to the first mounting seat, which is convenient for early installation and later disassembly and replacement, and is used to replace different power tools and power appliances.

[0007] Preferably, any of the above schemes is that the top end of the outer circumferential surface of the conical gasket is in contact with the inclined surface, and six through grooves are provided on the outer circumferential surface of the conical gasket. By using this scheme, the top end of the conical gasket can be elastically deformed to a certain extent, and the top end of the conical gasket can slide along the inclined surface by pushing the locking ring, thereby facilitating the clamping of the second round tube.

[0008] Preferably, any of the above schemes has an outer diameter of the locking ring that is the same as the outer diameter of the second mounting seat and the first circular tube, and the top of the locking ring is stepped. By using this scheme, after the bottom end of the locking ring is threadedly connected to the bottom end of the second mounting seat, the outer cylindrical surface of the locking ring and the outer cylindrical surface of the second mounting seat can be overlapped with each other. At the same time, the stepped structure of the locking ring facilitates threaded connection with the inner wall of the second mounting seat, which facilitates the pushing of the conical gasket.

[0009] Preferably, any of the above schemes is that the bottom end of the outer wall of the second circular tube is sleeved with an operating handle. By using this scheme, it is convenient to provide a gripping position for the user. At the same time, the material of the operating handle can be insulating rubber, which on the one hand increases the friction between the user's hand, and on the other hand improves the insulation performance between the user's hand, making it convenient for the user to perform live operation.

[0010] The utility model has the following advantages:

[0011] 1. The insulating rod for testing high-voltage power equipment is provided with a first round tube and a second round tube, so that the second round tube can slide inside the first round tube to adjust the length extending out of the first round tube. A locking ring and a conical gasket are provided, the locking ring is rotated to push the conical gasket, and the conical gasket slides along the inclined surface to clamp the second round tube, thereby increasing the friction between the conical gasket and the locking ring, fixing the position of the second round tube, thereby increasing the distance between the operator and the power equipment and reducing the operator's use risk.

[0019] The utility model is further described below in conjunction with the accompanying drawings, but the protection scope of the utility model is not limited to the following description.

[0020] like Figures 1 to 5 As shown, an insulating rod for testing high-voltage power equipment includes a first circular tube 1 and a second circular tube 2. The first circular tube 1 is located on the outer wall of the second circular tube 2. A first mounting seat 7 is provided at the top of the first circular tube 1. A second mounting seat 4 is fixedly connected to the bottom end of the first circular tube 1. An inclined surface 11 is provided in the middle of the inner wall of the second mounting seat 4. A conical gasket 10 is provided inside the second mounting seat 4. A locking ring 8 is threadedly connected to the bottom end of the inner wall of the second mounting seat 4. The top of the locking ring 8 fits with the bottom surface of the conical gasket 10.

[0021] Both ends of the inner wall of the first circular tube 1 are fixedly connected to the outer walls of the first mounting seat 7 and the second mounting seat 4 by rivets respectively. As an optional technical solution of the utility model, this facilitates the first mounting seat 7 and the second mounting seat 4 to be stably installed at the two end positions of the first circular tube 1. At the same time, the rivet connection can avoid relative sliding between the first mounting seat 7 and the second mounting seat 4 and the first circular tube 1, making it convenient for the user to relatively rotate the locking ring 8 and the second mounting seat 4, and the first mounting seat 7 and the fixing plate 5.

[0022] A threaded hole is provided in the middle of the first mounting seat 7, a fixing plate 5 is provided at the top of the first mounting seat 7, and a clamping tool 6 is fixedly connected to the top of the fixing plate 5, a threaded column 9 is fixedly connected to the bottom of the fixing plate 5, and the threaded column 9 is threadedly connected to the threaded hole. As an optional technical solution of the utility model, this facilitates relative rotation between the fixing plate 5 and the first mounting seat 7, facilitates early installation and later disassembly and replacement, and is used to replace different power tools and power appliances.

[0023] The top end of the outer circumferential surface of the conical gasket 10 fits with the inclined surface 11, and six through grooves 13 are provided on the outer circumferential surface of the conical gasket 10. As an optional technical solution of the utility model, this facilitates the top end of the conical gasket 10 to undergo a certain degree of elastic deformation, and through the pushing of the locking ring 8, the top end of the conical gasket 10 slides along the inclined surface 11, thereby facilitating the clamping of the second round tube 2.

[0024] The outer diameter of the locking ring 8 is the same as the outer diameter of the second mounting seat 4 and the first circular tube 1, and the top of the locking ring 8 is stepped. As an optional technical solution of the utility model, it is convenient to make the outer cylindrical surface of the locking ring 8 coincide with the outer cylindrical surface of the second mounting seat 4 after the bottom end of the locking ring 8 is threadedly connected to the bottom end of the second mounting seat 4. At the same time, the stepped structure of the locking ring 8 facilitates threaded connection with the inner wall of the second mounting seat 4, which facilitates the pushing of the conical gasket 10.

[0025] An operating handle 3 is sleeved on the bottom end of the outer wall of the second circular tube 2, which is an optional technical solution of the present invention. This facilitates providing a gripping position for the user. At the same time, the operating handle 3 can be made of insulating rubber, which, on the one hand, increases the friction between the user's hand and, on the other hand, improves the insulation performance between the user's hand, making it easier for the user to perform live operations.

[0026] The following steps are required when using the insulating rod for high-voltage power equipment testing:

[0027] 1) When in use, the conical gasket 10 is in a relaxed state, and the operator pulls the second round tube 2 to adjust the length extending from the first round tube 1;

[0028] 2) Rotate the locking ring 8, one end of the locking ring 8 enters into the second mounting seat 4, and pushes the conical gasket 10;

[0029] 3) The conical gasket 10 slides along the inclined surface 11 , causing the top end of the conical gasket 10 to deform, thereby increasing the friction between the conical gasket 10 and the locking ring 8 , and fixing the position of the second round tube 2 .

[0030] To sum up, when the user uses it, by setting the first circular tube 1 and the second circular tube 2, it is convenient to make the second circular tube 2 slide inside the first circular tube 1 to adjust the length extending out of the first circular tube 1, by setting the locking ring 8 and the conical gasket 10, rotating the locking ring 8, pushing the conical gasket 10, and at the same time the conical gasket 10 slides along the inclined surface 11, which is convenient for clamping the second circular tube 2, increasing the friction between the conical gasket 10 and the locking ring 8, and fixing the position of the second circular tube 2, thereby increasing the distance between the operator and the power equipment and reducing the risk of use for the operator, and then by setting the first circular tube 1 and the first mounting seat 7, the two are fixedly connected by rivets, so that the two are stably connected, and at the same time the fixing plate 5 is threadedly connected to the first mounting seat 7, so that the two are convenient for quick connection and quick disassembly, and are used to install different power tools or electrical testers and other instruments on the top of the first mounting seat 7, thereby improving the practicality of the insulating rod.
