Abstract
The utility model discloses a through-wall protection tube. The through-wall protection tube comprises a metal tube body, wherein an outer wall of the metal tube body is provided with multiple high-wing rings and multiple low-wing rings, the high-wing rings and the multiple low-wing rings are alternatively arranged, an inner portion of the metal tube body is provided with a cross separation plate, and an inner wall of the metal tube body and an outer surface of the cross separation plate are respectively provided with an insulation layer. Through a scheme above, the through-wall protection tube enables line to pass through a wall body in a separation arrangement mode, so distinguishing is easy, moreover, the through-wall protection tube further has advantages of good insulation performance and high strength in combination with the wall body.
Description
Technical field
The utility model relates to the civil air defense constructions and installations technical field, particularly relates to a kind of protection tube through walls.
Background technology
Wall bushing is called wall pipe again, water string, and the pre-pipe laying of body of wall is widely used in present building.Wall bushing mainly is mounted on the body of wall of basement in civil air defense constructions and installations, is convenient to pipeline, circuit etc. and passes body of wall.When existing wall bushing was used to allow circuit pass body of wall, various circuits were mixed in together, difficult the resolution.In addition, existing wall bushing insulation property are bad, and the bond strength between the body of wall is not high.
The utility model content
The technical problem that the utility model mainly solves provides a kind of protection tube through walls, can solve problems of the prior art, arranged apart in the time of can allowing circuit pass body of wall, differentiate easily, also has good insulating in addition, the advantage high with the body of wall bond strength.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of protection tube through walls is provided, comprise: the metal sleeve body, the outer wall of described metal sleeve body is provided with a plurality of shoulder wing rings and a plurality of low wing ring, described a plurality of shoulder wing ring and a plurality of low wing central spacer arrange, the inside of described metal sleeve body is provided with a cross demarcation strip, is equipped with insulating barrier on the outer surface of the inwall of described metal sleeve body and cross demarcation strip.
In preferred embodiment of the utility model, described cross demarcation strip adopts metallic plate to make.
In preferred embodiment of the utility model, between described cross demarcation strip and the metal sleeve body by being welded to connect.
In preferred embodiment of the utility model, described insulating barrier adopts ceramic insulating layer.
The beneficial effects of the utility model are: the utility model protection tube through walls, and arranged apart in the time of can allowing circuit pass body of wall, differentiate easily, also have good insulating in addition, the advantage high with the body of wall bond strength.
Description of drawings
Fig. 1 is the structural representation of the utility model protection tube one preferred embodiment through walls;
Fig. 2 is the end view of Fig. 1;
The mark of each parts is as follows in the accompanying drawing: 1, metal sleeve body, 2, the shoulder wing ring, 3, low wing ring, 4, the cross demarcation strip.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection range of the present utility model is made more explicit defining.
See also Fig. 1 and Fig. 2, the utility model embodiment comprises:
A kind of protection tube through walls, comprise: metal sleeve body 1, the outer wall of described metal sleeve body 1 is provided with a plurality of shoulder wing rings 2 and a plurality of low wing ring 3, described a plurality of shoulder wing ring 2 and a plurality of low wing ring 3 arrange at interval, the inside of described metal sleeve body 1 is provided with a cross demarcation strip 4, is equipped with insulating barrier on the outer surface of the inwall of described metal sleeve body 1 and cross demarcation strip 4.
By cross demarcation strip 4 is set, the inner space of metal sleeve body 1 is divided into four parts, can allow different circuits arranged apart, differentiate easily.
Described a plurality of shoulder wing ring 2 and a plurality of low wing ring 3 have strengthened the bond strength between protection tube through walls and the body of wall greatly.
Be equipped with insulating barrier on the outer surface of the inwall of described metal sleeve body 1 and cross demarcation strip 4, strengthened the insulation property of protection tube through walls.
Described cross demarcation strip 4 adopts metallic plate to make.
Between described cross demarcation strip 4 and the metal sleeve body 1 by being welded to connect.
Described insulating barrier adopts ceramic insulating layer.
The utility model protection tube through walls, arranged apart in the time of can allowing circuit pass body of wall, differentiate easily, also have good insulating in addition, the advantage high with the body of wall bond strength.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
