[0002] During the routine maintenance and switching operation of substations, the length of the grounding wire operating rod is often determined by the voltage level. The higher the high voltage level, the longer the insulating operating rod, which makes the insulating operating rod inconvenient to carry and transport. When splicing traditional grounding wire operating rods, on the one hand, the thread mouth needs to be precisely aligned, which requires at least two people to work together. This not only increases labor costs, but also causes the thread to slip due to slight deviations in the angle during installation, making the entire installation and disassembly time-consuming and inefficient. On the other hand, traditional grounding wire operating rods can often only be used for a single voltage level or a specific type of equipment, and cannot be multifunctional or universal, thus limiting the flexibility and applicability of the operating rod.

DETAILED DESCRIPTION

[0018] The present invention is not limited by the following embodiments, and specific implementation methods can be determined based on the technical solution of the present invention and actual conditions.

[0019] In the present invention, for the convenience of description, the relative position relationship of each component is described according to the attached Figure 1 The positional relationships such as front, back, top, bottom, left, and right are described according to the layout directions of the drawings in the specification.

[0020] The present invention will be further described below in conjunction with embodiments and drawings: Embodiment 1: As attached Figure 1 , 2 As shown in Figures 3 and 4, the screw-on pipe fitting clip comprises a clip rod 1 and a rubber sleeve, a mounting ring groove 4 is provided on the outer side of the lower part of the clip rod 1, a rubber sleeve is provided in the mounting ring groove 4, the rubber sleeve comprises a first half-cylinder 2 and a second half-cylinder 3 which are separately arranged, the inner sides of the middle parts of the first half-cylinder 2 and the second half-cylinder 3 are both provided with a locking ridge 5 which is arranged vertically, an unlocking long groove 6 is provided on the clip rod 1 corresponding to the position of the locking ridge 5, the locking ridge 5 is located in the unlocking long groove 6 at the corresponding position, a mounting hole 7 which opens upward is provided on the upper side of the clip rod 1, a socket ring groove 8 is provided on the clip rod 1 at the bottom position of the corresponding mounting hole 7. During use, two insulating rods with different outer diameters are used, wherein the insulating rod with a larger outer diameter is the outer tube, and the insulating rod with a smaller outer diameter is the inner tube. The inner diameter of the outer tube matches the rubber tube, the outer diameter of the inner tube matches the mounting hole 7, and the wall thickness of the inner tube matches the socket ring groove 8. After the lower end of the inner tube is inserted into the socket ring groove 8, the twisting pipe fitting buckle is inserted into the outer tube. After adjusting the distance between the upper end of the inner tube and the lower end of the outer tube, the inner tube is rotated to make the buckle rod 1 rotate with it relative to the outer tube. During the rotation process, due to the large friction between the outer side of the rubber tube and the inner side of the outer tube, the rubber tube does not rotate with the buckle rod 1. When the locking convex strip 5 is disengaged from the unlocking long groove 6, the locking convex strip 5 expands outward under the support of the outer side of the buckle, and the inner side of the outer tube is blocked, so that the inner tube cannot continue to move downward in the outer tube, thereby realizing the locking of the inner tube. After completing the relevant transmission line operation and maintenance operations, the inner tube is rotated in the opposite direction to make the locking convex strip 5 enter the unlocking long groove 6 to realize the unlocking of the inner tube.

[0021] The above-mentioned twist-on pipe fitting buckle can be further optimized and / or improved according to actual needs: Embodiment 2: As attached Figure 1 , 2 As shown in , 3 and 4, a plurality of deformation annular grooves 9 are arranged at intervals on the upper and lower sides of the outer side of the rubber cylinder. In the process of use, such an arrangement facilitates the rubber cylinder to expand outwards.

[0022] Embodiment 3: As attached Figures 1 to 6As shown, the telescopic insulating operating rod using the above-mentioned twisting pipe buckle comprises a twisting pipe buckle and at least two telescopic tubes 10 arranged at intervals from the inside to the outside, and a twisting pipe buckle matching the two is provided between each two inner and outer adjacent telescopic tubes 10, and the lower ends of the telescopic tubes 10 located at the inner position are all located in the socket ring groove 8 at the corresponding position. During use, by setting the twisting pipe buckle, the total length of multiple telescopic tubes 10 can be quickly adjusted to meet the requirements for the length of the insulating operating rod under different voltage levels; by rotating the telescopic tube 10 located at the inner side, the relative position between it and the telescopic rod located at the outer side is locked, which can effectively solve the problem that the installation of the existing insulating operating rod is time-consuming and labor-intensive and it is inconvenient to adjust the length. According to the needs, the telescopic rod inserted into the socket ring groove 8 can adopt an interference fit or a key connection to achieve the rotation of the telescopic rod and the buckle rod 1 together, wherein the key connection can be a key block set at the lower end of the telescopic rod, and a key groove set at the bottom of the socket ring groove 8; the rubber cylinder and the telescopic rod on its outside can adopt a clearance fit, so as to facilitate the adjustment of the length between the two telescopic rods set inside and outside before the rubber cylinder expands.

[0023] The above-mentioned telescopic insulating operating rod can be further optimized and / or improved according to actual needs: Embodiment 4: As attached Figures 1 to 6 As shown, a protective cap 11 is also included, and a protective cap 11 is provided on the outer side of the telescopic tube 10 corresponding to the upper position of each twist-type pipe fitting buckle. During use, the protective cap 11 is arranged so that its lower part is located on the outer side of the upper end of the outer telescopic tube 10 at the corresponding position, so that the upper part of the protective cap 11 is located on the outer side of the inner telescopic tube 10 at the corresponding position. According to requirements, the hole on the inner side of the upper part of the protective cap 11 matches the outer diameter of the inner telescopic tube 10 at the corresponding position, and the hole on the inner side of the lower part of the protective cap 11 matches the outer diameter of the outer telescopic tube 10 at the corresponding position.

[0024] Embodiment 5: As attached Figures 1 to 6 As shown, a protective ring 12 is also included. The protective ring 12 is provided on the outer side of the middle part of the outermost telescopic tube 10, and a conspicuous layer is provided on the outer side of the telescopic tube 10 below the protective ring 12. By providing the protective ring 12 and the conspicuous layer, the operator is reminded not to touch the telescopic tube 10 above the protective ring 12. According to the requirements, the conspicuous layer can be a red tube section, and the rest can be yellow tube sections.

[0025] Embodiment 6: As attached Figures 1 to 6As shown, a quick connector 13 is also included. The upper end of the inner telescopic tube 10 of each of the two inner and outer adjacent telescopic tubes 10 is located above the outer telescopic tube 10. The outer side of the upper end of the telescopic tube 10 located at the upper position is fixedly installed with a quick connector 13. The quick connector 13 can be quickly installed with the electroscope head, the grounding wire head or the insulating rod head. During use, by setting the quick connector 13, the electroscope head, the grounding wire head or the insulating rod head can be quickly disassembled and assembled, which meets the maintenance requirements of different transmission lines and effectively solves the problem of the single function of the existing insulating operating rod.
