[0025] In order to make the above-mentioned objects, features, and advantages of the present utility model more obvious and understandable, the following will make a detailed description of the specific embodiments of the present utility model in conjunction with the drawings of the specification.

[0026] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0027] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that can be included in at least one implementation manner of the present utility model. The "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is separately or selectively mutually exclusive with other embodiments.

[0028] Embodiment 1

[0029] Refer to Figures 1 to 3, which is the first embodiment of the present utility model. This embodiment provides an insulator connection device, including an insulating unit 100, which includes an insulator string 101. The lower end of the insulator string 101 is a fixed end 101a, and the upper end is a connection end 101b;

[0030] A fixing unit 200, including a control end joint 201 that cooperates with the fixed end 101a, and a fixing component 202 disposed inside the fixed end 101a. The fixing component 202 also cooperates with the control end joint 201;

[0031] Furthermore, the insulator string 101 is formed by connecting a plurality of insulators 101c in series, which is used to achieve high-voltage insulation between the tool end and the control end, and prevent the high voltage of the wire from damaging the control end equipment during operation. The insulator 101c is bell-shaped, and its covering direction is on the side of the fixed end 101a, which can reduce the accumulation of dirt.

[0032] Furthermore, a block groove 101a-1 is opened inside the fixed end 101a. Both ends of the block groove 101a-1 penetrate the fixed end 101a horizontally to form a block through hole 101a-2. A threaded section 101a-3 is also provided on the outside of the fixed end 101a. The threaded section 101a-3 covers the upper block through hole 101a-2, and the other block through hole 101a-2 is outside the coverage of the threaded section 101a-3.

[0033] Furthermore, the upper end of the control end joint 201 is a fixed groove 201a, which cooperates with the fixed end 101a, and their circumferential diameters are the same. Clamping and positioning holes 201b are symmetrically opened at the upper end of the side wall of the fixed groove 201a. When fixedly connected to the insulator string 101, the clamping and positioning holes 201b are opposite to the lower block through hole 101a-2.

[0034] Furthermore, the fixing component 202 includes clamping and positioning blocks 202a disposed in the block groove 101a-1. There are two clamping and positioning blocks 202a symmetrically arranged along the block groove 101a-1, which are used to connect and fix the insulator string 101 and the control end joint 201. The clamping and positioning blocks 202a are connected and cooperated through a block spring 202b. The fixing component 202 also includes a fixing nut 202c disposed outside the threaded section 101a-3, which can cooperate with the clamping and positioning blocks 202a when rotating and adjusting along the threaded section 101a-3.

[0035] Further, one end of the clamping and positioning block 202a extends out of the block through-hole 101a-2 and is provided with a fixing block 202a-1, which is a triangular inclined plane block, and the inclined plane faces away from the fixing nut 202c. The fixing block 202a-1 cooperates with the clamping and positioning hole 201b. The other end of the clamping and positioning block 202a extends out of the block through-hole 101a-2 and is provided with an opening and closing block 202a-2, which has the same shape and direction as the fixing block 202a-1 and cooperates with the fixing nut 202c. Usually, under the action of the block spring 202b, the fixing block 202a-1 and the opening and closing block 202a-2 extend out of the block through-hole 101a-2. When the fixing nut 202c is screwed upward, it can squeeze the opening and closing block 202a-2 to make the clamping and positioning block 202a retract into the block groove 101a-1.

[0036] During use, the fixed end 101a is plugged and connected according to the positions of the fixing block 202a-1 and the clamping and positioning hole 201b. When the fixing block 202a-1 contacts the upper side edge of the fixing groove 201a, it is squeezed and locked into the block groove 101a-1. After the plugging is completed, under the action of the block spring 202b, the fixing block 202a-1 pops out and cooperates with the clamping and positioning hole 201b. At this time, the fixing nut 202c is screwed to clamp the control end joint 201 in cooperation with the fixing block 202a-1, so that the insulator string 101 is fixedly connected to it.

[0037] In summary, the fixing unit 200 is used to connect and fix the insulator string 101 and the control end, ensuring accurate and stable connection positioning while enabling quick disassembly and assembly.

[0038] Embodiment 2

[0039] Refer to Figures 1 to 4 , which is the second embodiment of the present invention. Based on the previous embodiment, this embodiment provides an insulator connection device, further including: a connection unit 300, including a tool end joint 301 that cooperates with the connection end 101b, and a connection component 302 disposed inside the connection end 101b, and the connection component 302 cooperates with the tool end joint 301 at the same time.

[0040] Further, an arc-shaped connection groove 101b-1 is opened at the upper end of the connection end 101b, which is narrow at the top and wide at the bottom in cross-section, and two are arranged in a circumferential array along the connection end 101b. A limiting block groove 101b-2 is further opened below the arc-shaped connection groove 101b-1, and its width is the same as the width of the lower side of the arc-shaped connection groove 101b-1. An entrance groove 101b-3 is opened at one end of the arc-shaped connection groove 101b-1, and its width is the same as the width of the limiting block groove 101b-2. An adjustment groove 101b-4 is opened through the side wall of the connection end 101b at the position of the limiting block groove 101b-2, and the adjustment groove 101b-4 communicates with the two limiting block grooves 101b-2 on both sides.

[0041] Further, two connecting claws 301a are arranged in a circumferential array on the lower side of the tool end joint 301. Their shapes are arc-shaped and are matched with the arc-shaped connecting groove 101b-1 for connecting the tool end joint 301 and the insulator string 101. A clamping head 301b is also arranged at the lower end inside the connecting claw 301a, and it has the same shape as the entrance groove 101b-3.

[0042] Further, the connecting component 302 includes a limiting block 302a arranged in the limiting block groove 101b-2 and a limiting spring 302b fixedly arranged on the lower side of the limiting block groove 101b-2 and matched with the limiting block 302a. The limiting block 302a is used to limit the connecting claw 301a, and after the connection and cooperation, the limiting block 302a can prevent it from disengaging.

[0043] Further, both ends of the limiting block 302a are adjusting plates 302a-1, which are arranged in the adjusting groove 101b-4 and both ends extend out of the adjusting groove 101b-4. Under the action of the limiting spring 302b, the limiting block 302a extends to the top of the wide section of the arc-shaped connecting groove 101b-1, and at the same time, the adjusting plate 302a-1 is also located at the top of the adjusting groove 101b-4. When the adjusting plate 302a-1 is pressed to make it located at the bottom end of the adjusting groove 101b-4, the limiting block 302a also completely disengages from the arc-shaped connecting groove 101b-1.

[0044] During use, align the connecting claw 301a with the entrance groove 101b-3 and press down the tool end joint 301 until it can no longer be pressed down. During this process, the connecting claw 301a squeezes the limiting block 302a, causing it to move downward and disengage from the arc-shaped connecting groove 101b-1. Then rotate the tool end joint 301 so that the connecting claw 301a rotates along the arc-shaped connecting groove 101b-1 until it can no longer be rotated. When rotating to the limit, the connecting claw 301a disengages from the top of the limiting block 302a. Under the action of the limiting spring 302b, the limiting block 302a pops into the arc-shaped connecting groove 101b-1. At this time, the connecting claw 301a can no longer rotate reversely, and the connection is completed; when disassembly is required, press the adjusting plate 302a-1 to make it located at the bottom end of the adjusting groove 101b-4, and the limiting block 302a also completely disengages from the arc-shaped connecting groove 101b-1, releasing the limit on the connecting claw 301a. At this time, rotate the tool end joint 301 reversely to complete the disassembly.

[0045] In summary, by connecting the tool end and the insulator string 101 through the connecting unit 300, the rapid connection of the tool end can be realized, which is convenient for quick replacement of the tool in the later stage and when a failure occurs, and increases its applicability.
