[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model. Embodiment 1

[0021] Referring to Figures 1-4 The embodiment provides a reinforced insulation high-voltage conductor insulation sleeve, which comprises an insulation sleeve 1 and an extrusion structure, characterized in that a first annular groove 4 is formed in the inner wall of the insulation sleeve 1, a first sealing ring 5 is arranged in the first annular groove 4, two fixed sleeves 14 are fixedly connected to the outer wall of the insulation sleeve 1, threaded sleeves 15 are threadedly connected to the fixed sleeves 14, and the two threaded sleeves 15 are provided with the extrusion structure at the sides away from each other.

[0022] Hard fixed rings 2 are fixedly connected to the two ends of the insulation sleeve 1, and open slots 3 are formed in the hard fixed rings 2, and the open slots 3 are in a conical shape.

[0023] In use, the first annular groove 4 in the inner wall of the insulation sleeve 1 is provided with the first sealing ring 5, when the insulation sleeve 1 is sleeved on the high-voltage conductor, the first sealing ring 5 can preliminarily play a sealing role, reducing the entry of impurities such as air and water vapor from the gap between the insulation sleeve 1 and the conductor, the hard fixed rings 2 at the two ends of the insulation sleeve 1, the conical open slots 3 in the hard fixed rings 2 can guide the insulation sleeve 1 to be accurately sleeved on the high-voltage conductor when the insulation sleeve is installed, facilitating installation operation, and the hard fixed rings 2 can enhance the structural strength of the two ends of the insulation sleeve 1, preventing deformation or damage due to stress in use, and guaranteeing the reliability of the insulation sleeve. Embodiment 2

[0024] Referring to Figures 1-4The embodiment is based on the previous embodiment, and differs from the previous embodiment in that the extrusion structure comprises a connecting sleeve 10, a second annular groove 11, a second sealing ring 12 and a third annular groove 13, two of the threaded sleeves 15 are fixedly connected with the connecting sleeve 10 at the distal ends thereof, the connecting sleeve 10 is internally provided with the second annular groove 11, the second annular groove 11 is internally embedded with the second sealing ring 12, and the connecting sleeve 10 is internally provided with the third annular groove 13, and the third annular groove 13 has a trapezoidal cross section.

[0025] The outer side wall of the insulating sleeve 1 is provided with a plurality of placement grooves 6, and the placement grooves 6 are internally provided with top blocks 7, and the top blocks 7 are parallel to the first sealing ring 5.

[0026] The distal end of the top block 7 away from the first sealing ring 5 is fixedly connected with an abutting block 8, the abutting block 8 has a trapezoidal shape, and the abutting block 8 is in sliding connection with the placement groove 6.

[0027] The inner side of the insulating sleeve 1 and located at the distal end of the plurality of placement grooves 6 away from the connecting sleeve 10 is provided with a through groove 9, the through groove 9 is matched with the top block 7, and the through groove 9 is in communication with the first annular groove 4.

[0028] In use, the placement groove 6 on the outer side wall of the insulating sleeve 1 is provided with a top block 7, and the abutting block 8 connected to one end of the top block 7 has a trapezoidal shape and is in sliding connection with the placement groove 6. When the threaded sleeve 15 is rotated, the threaded sleeve 15 will drive the connecting sleeve 10 to move on the insulating sleeve 1, thereby driving the third annular groove 13 to move, and the cross section of the third annular groove 13 is trapezoidal. The inclined surface of the third annular groove 13 will gradually come into contact with the abutting block 8 during movement and extrude the abutting block 8. The abutting block 8 will slide inward along the placement groove 6 due to extrusion. Since the abutting block 8 is fixedly connected with the top block 7, the top block 7 will move through the through groove 9 to the first sealing ring 5 and extrude the first sealing ring 5, so that the first sealing ring 5 is further deformed, thereby more closely adhering to the high-voltage conductor. The design of the through groove 9 provides space for the movement of the top block 7. In this way, not only is the sealing performance between the insulating sleeve 1 and the high-voltage conductor strengthened, effectively reducing the possibility of foreign matter entering the gap between the two, but also the insulation effect is improved, reducing the risk of safety accidents such as electric leakage and short circuit. As the threaded sleeve 15 continues to rotate, the extrusion force of the third annular groove 13 on the abutting block 8 changes constantly. The operator can adjust the extrusion force of the top block 7 on the first sealing ring 5 accurately by controlling the rotation degree of the threaded sleeve 15 to achieve the best sealing and adhesion state. The second annular groove 11 in the threaded sleeve 15 is embedded with a second sealing ring 12, which can play a sealing role to prevent impurities from entering from the connecting sleeve 10.
