Description
Technical Field
The utility model relates to a cable laying pipe specifically is a fire-retardant nothing halogen house ornamentation threading pipe.
Background
The threading pipe is a body that is used for protecting the cable, and during the use, the cable is worn to locate in the body, then buries underground in the wall. The PVC flame-retardant threading pipe is widely applied to the fields of electric cables and communication cables, and has a long-term important position in building threading pipe materials due to low price and simple manufacture.
However, the PVC threading pipe is easy to drip and delay burning in the burning process, and causes invisible damage to wires and cables inside, thus causing fire spreading and aggravation. And because PVC contains a large amount of halogen elements, when the threading pipe is ignited and burnt, a large amount of toxic smoke and dense fog are easily generated, so that the personnel can be damaged secondarily and the escape passage of the disaster-stricken personnel is blocked. In addition, PVC threading pipe end cable is directly worn out, does not have sealed protectiveness, and the intensity of a fire probably stretches to the threading pipe inside from the threading pipe end along the cable when the conflagration breaing out, can't play the effect of suppression.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a fire-retardant no halogen house ornamentation threading pipe 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 flame-retardant halogen-free home decoration threading pipe comprises an outer sleeve, an inner sleeve and a sealing cover, wherein the inner sleeve is glued and fixed in the outer sleeve;
the sealing cover is positioned at the end head of the inner sleeve and comprises an end cover and a cover body, the cover body is connected with a plurality of first elastic sheets integrated with the cover body, the first elastic sheets are symmetrically arranged in an array mode, the first elastic sheets are bent outwards, and the outer diameter of the end head of each bent first elastic sheet is larger than the inner diameter of the outer sleeve; a plurality of threading holes are arranged in an array mode in the end cover, the threading holes are connected with second elastic pieces, the sections of the second elastic pieces are arc-shaped and are bent inwards, and a layer of heat-resistant rubber layer is arranged on the inner sides of the second elastic pieces.
As a further aspect of the present invention: the cover body is provided with an arc-shaped groove, and a fireproof sealing ring is arranged in the arc-shaped groove.
As a further aspect of the present invention: the inner sleeve is an aluminum foil tube.
As a further aspect of the present invention: the outer sleeve is a low-smoke halogen-free flame-retardant pipe.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model adopts the sealing cover to seal the end of the threading pipe, thereby playing the effect of controlling the fire spread of the cable from the end; the low-smoke halogen-free flame-retardant pipe and the aluminum foil inner pipe are compounded, so that the toxic and corrosive gas and toxic smoke generated during combustion of the pipe can be effectively reduced, and the flame-retardant and flame-retardant effects on cables are achieved.

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 to 3, in an embodiment of the present invention, a flame retardant halogen-free home decoration threading tube includes an outer sleeve 1, an inner sleeve 2 and a sealing cover 4, wherein the inner sleeve 2 is fixed inside the outer sleeve 1 by gluing, the inner sleeve 2 is an aluminum foil material tube, the outer sleeve 1 is a low smoke halogen-free flame retardant tube, which can reduce toxic and corrosive gases and toxic smoke generated during combustion, and the aluminum foil tube of the inner layer has a flame retardant and flame retardant effect on the cable 3;
the sealing cover 4 is positioned at the end of the inner sleeve 2, the sealing cover 4 comprises an end cover 45 and a cover body 44, the cover body 44 is connected with a first elastic sheet 41 integrated with the cover body, the first elastic sheet 41 is symmetrically arranged in a plurality of arrays, the first elastic sheet 41 is bent and extended outwards (away from the central axis of the sealing cover 4), and has certain elasticity due to the bent shape, and generates elasticity after being pressed, and the outer diameter of the end of the first elastic sheet 41 is larger than the inner diameter of the outer sleeve 1 after being bent, when the sealing cover is installed, the first elastic sheet 41 is pressed and plugged into the outer sleeve 1, and the sealing cover 4 is fixed at the end of the outer sleeve 1 by utilizing the elasticity of the first elastic sheet 41 and the friction force between the first elastic sheet and the inner wall of; the end cover 45 is provided with a plurality of threading holes 46 in an array mode and used for the cable 3 to pass through, the threading holes 46 are connected with second elastic pieces 42, the cross sections of the second elastic pieces 42 are arc-shaped and bend and extend inwards (close to the central axis of the cover 4), a layer of heat-resistant rubber layer is arranged on the inner sides of the second elastic pieces 42, when the cable 3 passes through the threading holes 46, the cable 3 is pressed by the second elastic pieces 42 due to the fact that the diameter of the cable 3 is slightly larger than the inner diameter of the rubber layer cavity, so that the heat-resistant rubber layer is extruded and deformed and tightly pressed on the surface of the cable 3, the cable 3 is wrapped by the second elastic pieces 42, and if the cable 3 is spread to the heat-resistant rubber layer from outside combustion, the heat-resistant rubber layer has a.
