SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an overhead power transmission line jumper splicing sleeve to solve the problem that proposes in the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides an overhead power transmission line jumper wire splicing sleeve, includes the arc, the middle part of arc is equipped with first recess, the top fixedly connected with metal block of arc, the top swing joint of first recess has screw one, screw one has the splicing sleeve through first hole threaded connection, the spacing metal hole of one end fixedly connected with of splicing sleeve, the visor has been cup jointed through second recess activity to the one end of splicing sleeve.

Preferably, the inner thread of the limiting metal hole is connected with a second screw, and the second screw is connected with the two splicing sleeves through the limiting metal hole in a threaded manner.

Preferably, the outside joint of metal block has spacing spout.

Preferably, one side of the protective cover is provided with a third groove, and the protective cover is movably connected with a protective sleeve through the third groove.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses built on stilts power transmission line wire jumper splicing sleeve, the mode through threaded connection links together two splicing sleeves, it can be more inseparable the connection together to have realized two splicing sleeves, it produces not hard up influence transmission of electricity effect in daily use to have solved the splicing sleeve, through mutually supporting between the arc, the installation of different thickness size electric wires has been realized, the dismantlement in the later stage of also being convenient for is maintained, the area of contact of wire jumper and splicing sleeve has been increased simultaneously, the waste of transmission of electricity in-process electric power has been reduced, installation through the protective sheath, the safety of the protection complete equipment that can be better, the influence of weather environment to whole splicing sleeve device has been reduced, the efficiency and the safety of transmission of electricity in-process have been improved.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-7, the present invention provides a technical solution: the utility model provides an overhead power transmission line jumper wire splicing sleeve, includes arc 1, its characterized in that: a first groove 2 is arranged in the middle of the arc plate 1, a metal block 3 is fixedly connected with the top end of the arc plate 1, the top end of the first groove 2 is movably connected with a screw I4, the screw I4 is connected with a splicing sleeve 6 through a first hole 5 in a threaded manner, one end of the splicing sleeve 6 is fixedly connected with a limiting metal hole 7, one end of the splicing sleeve 6 is movably sleeved with a protective cover 13 through a second groove 8, when the splicing sleeve is installed, the electric wire is put into the splicing sleeve, the screw I4 is turned to be closed, the position of the jumper wire is adjusted to be fixed, the jumper wire is pressed by the arc-shaped plate 1, when the splicing sleeve is disassembled, the first adjusting screw 4 is rotated to separate the jumper wire from the arc-shaped plate 1, the electric wire is taken out, the assembly and disassembly of the splicing sleeve are facilitated, the subsequent change of the splicing sleeve can be more convenient, and each arc-shaped plate can be matched with the thickness conditions of different positions of the jumper wire, so that the jumper wire and the splicing sleeve are connected more closely.
