Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor are within the protection scope of the utility model.

[0023] Referring to Figures 1 to 5As shown, the utility model provides a detachable equalizing ring, include: ring body 1, the inside connection of ring body 1 has connecting assembly 2, and the inside connection of connecting assembly 2 has center ring 3, and the edge of center ring 3 is connected with compression assembly 4, and the outside swing joint of ring body 1 has reinforcing assembly 5, connecting assembly 2 includes with the fixed connection of center ring 3 outer wall screw rod 26, and the outside of screw rod 26 is screwed with threaded cylinder 24, and the outer end of threaded cylinder 24 is rotatably connected with inner clamping block 21, reinforcing assembly 5 includes hinged lever 51 hinged in the outer wall of ring body 1, and the outer end of hinged lever 51 is connected with hoop 52, both sides of hoop 52 are equipped with connecting lug 53, and connecting lug 53 is connected with fixed bolt 54 between, and reinforcing assembly 5 is equipped with three groups of equal interval arrangement on the circumference of ring body 1.

[0024] In the embodiment, ring body 1, connecting assembly 2, center ring 3, compression assembly 4 and reinforcing assembly 5 constitute the detachable equalizing ring main body structure involved in the application.

[0025] Wherein, ring body 1 and connecting assembly 2 are detachably connected, when transporting or transferring, after connecting assembly 2 is disassembled, the overall size of connecting assembly 2 can be made smaller by the contraction of threaded cylinder 24, thereby realizing the effect of convenient carrying.

[0026] Specifically, connecting assembly 2, center ring 3 and compression assembly 4 are all made of metal conductive material.

[0027] Specifically, after ring body 1 and connecting assembly 2 are disassembled, hinged lever 51 can be turned inward, so that it keeps a folded state with ring body 1, thereby realizing the effect of convenient placement.

[0028] Specifically, after the three hoops 52 included in reinforcing assembly 5 are connected, the small ring body structure formed forms a tapered structure similar to the upper wide and lower narrow structure, which environmentally fixes the insulating terminal and the terminal seat, and improves the stability of installation.

[0029] As Figures 1 to 4 Specifically, threaded cylinder 24 is screwed with locking bolt 25 on the outer wall, threaded cylinder 24 is fixed with connecting rod 23 on the outer end, connecting rod 23 is rotatably connected with adapter block 22, inner clamping block 21 is fixed on the outer end of adapter block 22, and clamping groove 211 is formed on the outer end of inner clamping block 21, compression assembly 4 includes handle screw bolt 41 screwed in the inside of center ring 3, handle screw bolt 41 is rotatably connected with clamp block 43 on the inside end, clamp block 43 is fixed with guide rod 42 on the outer wall, center ring 3 is screwed with stop bolt 31 on the outer wall, stop bolt 31 is in contact with handle screw bolt 41 inside center ring 3, connecting assembly 2 and compression assembly 4 are alternately arranged at equal intervals in the circumferential direction of center ring 3, and connecting assembly 2 and compression assembly 4 are all provided with three groups.

[0030] Specifically, the card slot 211 is designed as a U-shaped slot structure, and the two sets of connecting components 2 are set at a 60-degree angle.

[0031] As another preferred embodiment, by providing a retractable connecting component 2, it is easy to connect with equalizing rings of different diameters, thereby making it easier to determine the required equalizing ring size according to the insulation material of the terminal and the requirements of the power equipment.

[0032] In use, first, attach the central ring to the insulating terminal. Then, by rotating the handle bolt included in the crimping assembly, the drive clamp moves towards the insulating terminal. The insulating terminal is fixed by three sets of clamps. Then, tighten the anti-reverse bolt. Next, place the ring body outside the connecting assembly. At this point, simply rotate the threaded cylinder. Through the screw connection with the lead screw, the threaded cylinder moves outward, thereby driving the inner clamps to move outward until the slots of the three sets of inner clamps are engaged with the inner ring wall of the ring body. Then, tighten the locking bolt. For disassembly, simply rotate the threaded cylinder back. After the ring body is connected to the connecting assembly, rotate the hinge rod included in the reinforcing assembly downward so that the clamp on the lower side of the hinge rod engages with the outer wall of the terminal seat supported on the lower side of the insulating terminal. Then, fix the three sets of clamps with the fixing bolts and connecting ears, thereby adding a connection point on the lower side of the ring body. This allows for two-point fixation with the insulating terminal in conjunction with the crimping assembly, thus enhancing the wind resistance stability of the ring body.

[0033] The detachable equalizing ring of this invention can effectively solve the problems mentioned in the background technology, and achieves the effect of quick disassembly and installation on the basis of existing detachable equalizing ring technology, while increasing the wind resistance stability after installation.
