Abstract

A waterproof structure of an electric wire connecting pipe relates to an electric wire connecting pipe, and is characterized in that a seal ring (1) is arranged in an expanding hole (2) of a bushing (5) at one side, and a rubber ring (7) is sleeved on an outer screw thread (8) of a bushing (9) at the other side; an inner screw thread (6) of the bushing (5) at one side is connected with the outer screw thread (8) of the bushing (9) at the other side, and another one seal ring (1) is arranged in an expanding hole (2) of the bushing (5) at the other side. According to the utility model, the bushing (5) at one side, the bushing (9) at the other side, the seal rings and the rubber ring are used to seal a connection position of electric wires, so that the electric wire connection position is protected directly, a sparking phenomenon does not occur at an electric wire winding part, and rainwater or humidity does not penetrate the electric wire winding part.

Description

A kind of waterproof construction of wire connecting tube

[technical field]

The utility model relates to a kind of wire connecting tube, especially relates to a kind of waterproof construction of wire connecting tube.

[background technology]

Known, what the butt joint of present two wires was adopted is, uses the pliers that strips off the skin that the end crust of two strands of electric wires is pulled down, and utilizes pliers that two strands of electric wires are hinged then and tightens, and achieves UNICOM and reaches the purpose of transmission of electric energy; Owing to much the station that two strands of electric wires are tightened need be not suitable for two people operation simultaneously, so must be by the one-man service, it is very inconvenient that people catches two strands of electric wires to dock simultaneously, and electric wire is fastening not firm, and be subjected to the invasion and attack of rainwater or moisture, the accident potential that sparking occurs or disconnect easily easily in the junction.

[summary of the invention]

In order to overcome the deficiency in the background technology; the utility model discloses a kind of waterproof construction of wire connecting tube; the utility model utilizes a side sleeve pipe and opposite side sleeve pipe and sealing ring and rubber ring that the electric wire junction is directly protected, and the winding part that has guaranteed electric wire spark phenomenon can not occur and be subjected to the invasion and attack of rainwater or moisture.

For achieving the above object, the utility model adopts following technical scheme:

A kind of waterproof construction of wire connecting tube comprises a side sleeve pipe, opposite side sleeve pipe, sealing ring and rubber ring; End end face middle part at a side sleeve pipe is provided with expansion through the hole, the other end end face middle part internal thread of a described side sleeve pipe, and the side sleeve pipe between the hole is provided with the perforation of tie point putting hole and necking down successively at internal thread and expansion; Be provided with expansion through the hole at an end end face of opposite side sleeve pipe middle part, the other end outer edge surface of a described side sleeve pipe is provided with external screw thread, is provided with the tie point putting hole at the male end face, is provided with the perforation of necking down between the hole in tie point putting hole and expansion; The expansion of a described side sleeve pipe is provided with sealing ring in the hole, be with rubber ring at the external screw thread of opposite side sleeve pipe, and the internal thread of a side sleeve pipe is connected with the external screw thread of opposite side sleeve pipe, is provided with sealing ring in the expansion of opposite side sleeve pipe in the hole.

The waterproof construction of described wire connecting tube, the outer edge surface of a described side sleeve pipe is set to polygonal or ellipse.

The waterproof construction of described wire connecting tube, the outer edge surface of described opposite side sleeve pipe is set to polygonal or ellipse.

Owing to adopt aforesaid technical scheme, the utlity model has following superiority:

The waterproof construction of wire connecting tube described in the utility model; utilize a side sleeve pipe and opposite side sleeve pipe and sealing ring and rubber ring to form sealing to the electric wire junction; the electric wire junction is directly protected, guaranteed that spark phenomenon and the invasion and attack that are subjected to rainwater or moisture can not appear in the winding part of electric wire.

Fig. 1 is structural representation of the present utility model;

Fig. 2 is perspective view of the present utility model;

Among the figure: 1, sealing ring; 2, expand through the hole; 3, perforation; 4, tie point putting hole; 5, a side sleeve pipe; 6, internal thread; 7, rubber ring; 8, external screw thread; 9, opposite side sleeve pipe.

[embodiment]

By reference to the accompanying drawings to the utility model further instruction; The utility model is not limited to the following examples;

1 or 2 embodiment that provide by reference to the accompanying drawings, the waterproof construction of wire connecting tube described in the utility model comprises a side sleeve pipe 5, opposite side sleeve pipe 9, sealing ring 1 and rubber ring 7; Be provided with expansion at an end end face of a side sleeve pipe 5 middle part through the hole 2, the other end end face middle part internal thread 6 of a described side sleeve pipe 5 is provided with the perforation 3 of tie point putting hole 4 and necking down successively at internal thread 6 and the side sleeve pipe 5 of expansion between hole 2; Be provided with expansion at an end end face of opposite side sleeve pipe 9 middle part through the hole 2, the other end outer edge surface of a described side sleeve pipe 5 is provided with external screw thread 8, is provided with tie point putting hole 4 at external screw thread 8 end faces, is provided with the perforation 3 of necking down between hole 2 in tie point putting hole 4 and expansion; The expansion of a described side sleeve pipe 5 is provided with sealing ring 1 in hole 2, the internal thread 6 that is with rubber ring 7, one side sleeve pipes 5 at the external screw thread 8 of opposite side sleeve pipe 9 is connected with the external screw thread 8 of opposite side sleeve pipe 9, is provided with sealing ring 1 in the expansion of opposite side sleeve pipe 9 in hole 2; The outer edge surface of a wherein said side sleeve pipe 5 and opposite side sleeve pipe 9 is set to polygonal or ellipse.

Implement the waterproof construction of wire connecting tube described in the utility model, sealing ring 1 and a side sleeve pipe 5 are enclosed within link one side that needs to be connected electric wire, sealing ring 1 and opposite side sleeve pipe 9 be enclosed within needs the link of wire connecting opposite side, tighten the link of electric wire, put rubber ring 7 on the external screw thread 8 with opposite side sleeve pipe 9, internal thread 6 with a side sleeve pipe 5 is connected with the external screw thread 8 of opposite side sleeve pipe 9 then, after the connection two sealing rings 1 is filled in the expansion of a side sleeve pipe 5 and opposite side sleeve pipe 9 respectively in hole 2; The utility model has guaranteed that the electric wire junction can not expose; and the electric wire after twining is directly protected by a side sleeve pipe 5 and opposite side sleeve pipe 9; rubber ring 7 on the external screw thread 8 has also sealed screw connection point; the utility model has not only omitted existing adhesive tape and has twined; and can make the hinged comparatively all even firm of electric wire; waterproof, protection against the tide have guaranteed that the electric wire that twines part spark phenomenon can not occur.
