Example 1:

The fire connection operation is used as an operation project with highest frequency of live working, and a main line and a lead are generally connected together under the condition of live working through a parallel groove wire clamp, a C-shaped wire clamp, a J-shaped wire clamp and other fire connection wire clamps; in the live working, operators wearing insulating gloves hardly hold the elastic pad, the flat pad and the nut to put on the bolt, so that the elastic pad and the flat pad are easy to drop, and a certain risk is brought to live-line fire connection operation.

In view of the above problems, as shown in fig. 1, 2 and 3, the present embodiment provides an integrated sleeve for live working, which includes a sleeve body 3 and a gland 1 sleeved at one end of the sleeve body 3;

A magnetic ring 2 is arranged in the gland 1.

Specifically, sleeve body 3 one end passes through gland 1 sets up magnetic ring 2 can put into nut 7, bullet pad 6 and flat pad 5 in order under the magnetic force effect in sleeve body 3, flat pad 5 is under the suction of magnetic ring 2 with gland 1 terminal surface stable contact forms by nut 7 bullet pad 6 flat pad 5 and telescopic assembly, will be assembled as a whole and load into the fastener bolt, through rotatory sleeve body 3, can effectively with nut 7 bullet pad 6 with flat pad 5 integration is screwed up the fastener bolt on, has solved the operation personnel and has worn insulating glove and hardly held bullet pad, flat pad and nut and put into the bolt and cause bullet pad and flat pad to drop the problem.

It will be appreciated that one end of the gland 1 is provided with an inwardly protruding annular bead which can press the magnetic ring 2 against the end of the sleeve body 3. Correspondingly, a plurality of bolt holes 4 are formed in the side face of the gland 1, and jackscrews are arranged in the bolt holes 4 to fix the gland 1 on the sleeve body 3. Optionally, the plurality of bolt holes are uniformly distributed in the circumferential direction of the gland 1, so that the stability of connection between the gland 1 and the sleeve body 3 is improved.

The gland 1 can be processed by adopting ferromagnetic materials, so that the magnetic distribution of the ferromagnetic magnets can be increased and effectively uniform, and the nut 7, the spring pad 6 and the flat pad 5 can be more favorably and stably arranged in the sleeve of the sleeve body 3. The inside of the gland 1 can be set to be round, the inside diameter of the gland 1 is slightly larger than the outside diameter of the spring pad and the diagonal maximum size of the nut, so that the nut and the spring pad can be conveniently and smoothly put in, and the nut and the spring pad smoothly enter the sleeve when the wire clamp is disassembled.

Alternatively, the sleeve body 3 may be implemented by a conventional sleeve, and it is understood that an inner sleeve capable of tightening a nut is disposed in the sleeve body 3.

In this embodiment, the inner diameter and the outer diameter of the magnetic ring 2 are respectively equal to the inner diameter and the outer diameter of the sleeve body 3.

The working principle or process of the embodiment is as follows:

When the wire clamp is installed, the nut 7, the spring pad 6 and the flat pad 5 are sequentially placed into the sleeve in advance, the flat pad 5 is stably contacted with the end face of the gland 1 under the strong magnetic attraction force of the magnetic ring 2, a combination body of the nut 7, the spring pad 6, the flat pad 5 and the sleeve body 3 is formed, the combination body is integrally installed on the wire clamp bolt, the combination body can be screwed by an electric wrench and the like, and the nut 7, the spring pad 6 and the flat pad 5 are integrally screwed on the wire clamp bolt, so that single part falling is avoided.

When the wire clamp is disassembled, the sleeve at one end of the sleeve body 3 is arranged on a bolt of the wire clamp, after the nut is unscrewed by an electric wrench or a manual wrench, the nut 7, the spring pad 6 and the flat pad 5 are sequentially sucked into the strong magnetic sleeve under the strong magnetic action of the magnetic ring 2, and the flat pad 5 is stably adsorbed to the end face of the gland 1 under the strong magnetic action, so that a stable combination of the nut 7, the spring pad 6, the flat pad 5 and the sleeve body 3 is realized, and the risk that the sleeve body 3 falls after the wire clamp is disassembled is avoided.
