Description

Technical Field

[0001] The utility model relates to the technical field of electric power hardware, in particular to an electric testing grounding ring. Background Art

[0002] The test grounding ring is installed on the overhead insulated conductor and is used as a protective device for testing electricity and temporary grounding during maintenance and construction. The test grounding ring in the prior art includes an insulating wire clamp and a ring body of the test grounding ring, wherein the structure of the ring body is generally distributed in a square frame, as shown in the patent application number 201720065572.7 and the name is a test grounding ring device. In order to reduce the exposure of the two ends of its connection, a certain length of rubber insulation sleeve is also provided. When performing maintenance, when the operator hangs the hook of the grounding wire on the connection, the hook is often accidentally hung on the rubber insulation sleeves at both ends of the connection. At this time, the hook needs to be moved so that it is completely located at the connection, which wastes time. Utility Model Content

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a test grounding ring, including an insulating wire clamp and a ring body, the ring body including a clamping rod used to connect with the insulating wire clamp, both ends of the clamping rod are provided with vertical rods perpendicular to it, and the end of the vertical rod away from the clamping rod is provided with a retractable rod, the retractable rod gradually approaches the direction of the symmetry plane of the clamping rod in the direction from approaching to away from the vertical rod, and the two ends of the connecting rod are respectively connected to the ends of the two retractable rods away from the vertical rod, and the two ends of the clamping rod, the vertical rod and the outside of the retractable rod are provided with an insulating layer.

[0005] Preferably, the retractable rod is in the shape of a straight rod.

[0006] Preferably, the extension direction of the retractable rod is in an arc shape.

[0007] Preferably, the extension line of the connecting rod passes through the center of the virtual arc where the retractable rod is located.

[0008] Compared with the prior art, the utility model has the following advantages: vertical rods are provided at both ends of the clamping rod, a retractable rod is provided at the other end of the vertical rod, and the two ends of the connecting rod are respectively connected to the ends of the two retractable rods away from the vertical rods, and an insulating layer is provided at the two ends of the clamping rod, the vertical rod and the outside of the retractable rod. When connecting the grounding wire, the operator extends the hook of the grounding wire into the ring body, and when moving the hook downward, it hits the retractable rod and slides along the retractable rod to the connecting rod, which is very convenient and saves time.

[0012] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0013] Specific implementation method: Combination Figure 1-2 As shown, an electrical testing grounding ring includes an insulating wire clamp 1 and a ring body 2, one side of the insulating wire clamp 1 is connected to the ring body 2, and the other side is used to connect an insulated wire (transmission line). The ring body 2 includes a clamping rod 21 used to connect to the insulating wire clamp 1, and both ends of the clamping rod 21 are provided with vertical rods 22 perpendicular to the clamping rod 21, and one end of the vertical rod 22 away from the clamping rod 21 is provided with a retracting rod 23, and the retracting rod 23 gradually approaches the direction of the symmetry plane of the clamping rod 21 from approaching to away from the vertical rod 22, and the two ends of the connecting rod 24 are respectively connected to the ends of the two retracting rods 23 away from the vertical rod 22, and the connecting rod 24 is used to hang the hook of the grounding wire, and the two ends of the clamping rod 21, the vertical rod 22 and the outside of the retracting rod 23 are provided with an insulating layer. When the operator hangs the hook of the grounding wire on the connecting rod 24, after the hook extends into the ring body 2, when the hook moves downward, it will hit the retracting rod 23 and slide down to the connecting rod 24 along the retracting rod 23, which is very convenient and saves time. In addition, in the prior art, in order to facilitate hanging the hook on the exposed part of the connecting rod 24, the exposed length of the connecting rod 24 is relatively long, while in the present application, the length of the connecting rod 24 can be made relatively short. Although the connecting rod 24 is completely exposed, the exposed length is reduced.

[0014] As an embodiment of the present application, the retractable rod 23 is in the shape of a straight rod (not shown in the figure), and the straight rod is inclined with the connecting rod 24 and the vertical rod 23 .

[0015] As another embodiment of the present application, the extension direction of the retractable rod 23 is in the shape of an arc (the central angle corresponding to the arc is preferably less than 70°), and the extension line of the connecting rod 24 passes through the center of the virtual arc where the retractable rod 23 is located, so that the extension direction of the part of the retractable rod 23 that is connected to the connecting rod 24 is perpendicular to the connecting rod 24. When the hook of the grounding wire contacts the retractable rod 23, the contact point is mostly located below the middle of the retractable rod 23. Since the part below the middle gradually approaches verticality, the hook is easier to slide along the retractable rod 23 to the connecting rod 24.

[0016] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent transformations made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in the relevant technical field, are also included in the patent protection scope of the present invention.
