[0034] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0035] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings. Example

[0036] Please refer to Figure 1-4 A wire support for a high-voltage cable comprises a crossarm body 1, the upper surface of the crossarm body 1 is provided with four mounting holes 11, the front side surface of the lower side of the outer surface of the crossarm body 1 is slidably connected with a fixing ring 12, both ends of the fixing ring 12 extend to the rear side of the crossarm body 1 and are threadedly connected with nuts 13, the center position of the front side surface of the crossarm body 1 is arranged in a curved surface, a cavity 14 is arranged on the top side of the fixing ring 12, extending from the inside of the crossarm body 1 to the front surface of the crossarm body 1, the front side of the bottom of the inner surface of the cavity 14 is slidably connected with a fixing piece for pre-fixing the position of the crossarm body 1, a slide groove 21 is arranged on the rear side of the bottom of the inner surface of the cavity 14, the inner surface of the slide groove 21 is slidably provided with an elastic piece for resetting, two rotating rods 25 are fixedly connected to the two sides of the bottom of the inner surface of the cavity 14, and the outer surface of the rotating rod 25 is rotatably connected with a linkage piece. The fixing part includes a clamping plate 3, a slide groove 31 is provided on the front side of the bottom of the inner surface of the cavity 14, the bottom end of the clamping plate 3 is slidably arranged with the slide groove 31, and the clamping plate 3 is mirrored with the slide groove 31. The inner end of the clamping plate 3 is arranged in a curved surface. The elastic part includes a sliding plate 2, the sliding plate 2 is slidably arranged with the slide groove 1 21, and a strong spring 22 is fixedly connected between the rear side of the outer surface of the sliding plate 2 and the rear side of the inner surface of the cavity 14, and four strong springs 22 are arranged in a linear array. Slide grooves 23 are provided on both sides of the front side of the sliding plate 2, and the inner surface of the slide groove 23 is slidably connected with a slider 24. The linkage part includes a rotating plate 1 26, the rotating plate 1 26 is rotatably arranged with the rotating rod 25, one end of the lower surface of the clamping plate 3 is rotatably connected with the rotating plate 2 27 through a connecting rod, and the upper and lower surfaces of the slider 24 are rotatably connected with the rotating plate 1 26 and the rotating plate 2 27 through a rotating shaft.

[0037] Implementation process: The initial positions of the fixing ring 12 and the nut 13 are located on the outside of the crossarm body 1. When the crossarm body 1 needs to be installed, the curved surface of the crossarm body 1 is facing the electric pole, and the crossarm body 1 is pushed. Because one end of the clamping plate 3 is arranged in a curved surface, the clamping plate 3 moves to both sides under the action of the reaction force of the electric pole. Because the rotating plate 2 27 is rotatably arranged with the clamping plate 3, the rotating plate 1 26 is rotatably arranged with the rotating rod 25, and the rotating plate 1 26 and the rotating plate 27 are rotatably connected with the slider 24 through the rotating shaft, the movement of the clamping plate 3 drives the slider 24 slides to the other end of the second slide groove 23 under the action of the second slide groove 23. The sliding of the slider 24 drives the sliding plate 2 to move toward the rear side of the inner surface of the cavity 14 under the action of the first slide groove 21, and compresses the strong spring 22, and continues to push the cross arm body 1, so that the center position of the inner side of the clamping plate 3 moves to the two sides of the electric pole. At the same time, the curved surface position of the cross arm body 1 contacts the electric pole, and the elastic force of the strong spring 22 pushes the clamping plate 3 to move in the direction of the electric pole to clamp the electric pole, thereby realizing the preliminary pre-fixation of the cross arm body 1. When the fixation needs to be released, the reverse operation can be performed.

[0038] Implementation benefits: The position of the cross arm body 1 is pre-fixed to prevent the two ends from sagging due to the long length of the metal plates on both sides of the cross arm, resulting in unstable installation of the cross arm during installation. Example

[0039] Four mounting holes 11 are provided on the upper surface of the cross arm body 1. A fixing ring 12 is slidably connected to the front side of the lower outer surface of the cross arm body 1. Both ends of the fixing ring 12 extend to the rear side of the cross arm body 1 and are threadedly connected to nuts 13.

[0040] Implementation process: After the pre-fixing is achieved, the fixing ring 12 is inserted into the rear side of the crossarm body 1, and the nuts 13 are rotated at both ends of the fixing ring 12 to a position that fits with the crossarm body 1, thereby fixing the position of the crossarm body 1. After the fixing is completed, the external winding porcelain pot is fixed to the upper surface of the crossarm body 1 through the mounting hole 11 to achieve subsequent winding operations.

[0041] Implementation benefits: Achieved stable fixing effect on the cross arm.

[0042] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the invention are included in the scope of the claims of the present invention.
