Abstract
The utility model relates to an electrician's sleeve pipe technical field especially relates to a fire-retardant type electrician's sleeve pipe. Including adopting the sectional type to tear the area, the area of tearing of required distance has been realized freely tearing when the demand, thereby make electrician's sleeve pipe flexible be required angle, and when not tearing the area of tearing, make electrician's sleeve pipe possess stronger intensity and fire behaviour again, solved ordinary electrician's sleeve pipe and can't guarantee the straight line and lay the problem of flexible again in intensity, adopt the built-in fire-retardant layer of outer body, the function of reinforcing electrician's sleeve pipe flame retardant efficiency has been realized, the problem that fire resistance reduces when having solved ordinary electrician's sleeve pipe and crooked.
Description
Technical Field
The utility model relates to an electrician's sleeve pipe technical field especially relates to a fire-retardant type electrician's sleeve pipe.
Background
An electrical casing is a hard PVC rubber pipe, and when the electrical casing is used and laid in daily life, the hard casing is inconvenient to turn and the flame retardant property of the casing is affected due to the fact that the hard casing needs to turn frequently; the soft sleeve is convenient to turn, but cannot achieve the expected strength and flame retardant property when being laid in a straight line.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem, it is not enough to the technique that exists as above, a fire-retardant type electrician's sleeve pipe is provided, adopt the sectional type to tear the area, the area of tearing of required distance has been realized freely tearing when the demand, thereby make electrician's sleeve pipe flexible be required angle, and when not tearing the area of tearing, make electrician's sleeve pipe possess stronger intensity and fire behaviour again, the problem of bendable again when having solved ordinary electrician's sleeve pipe and can't laying intensity guaranteeing the straight line is solved, adopt outer internal fire-retardant layer that embeds, the function of reinforcing electrician's sleeve pipe flame retardant efficiency has been realized, the problem that fire resistance reduces when having solved ordinary electrician's sleeve pipe.
In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: comprises an outer tube body, a flame-retardant layer, a tear tape and a connecting bridge; the outer wall of the outer tube body is provided with a thread mounting groove; the inner wall of the outer pipe body is provided with a corrugated groove; the flame-retardant layer is arranged in the outer pipe body; the inner wall of the outer tube body is clamped with the flame-retardant layer; connecting bridges are arranged on two sides of the tear tape; the tear tape is fixedly connected with the thread mounting groove through the connecting bridge.
Further optimize this technical scheme, it is a plurality of connect the bridge equidistance and arrange in tearing the area both sides.
Further optimizing the technical scheme, the inner wall of the flame retardant layer is provided with a corrugated groove; the flame-retardant layer is provided with a mounting groove.
Further optimizing the technical scheme, a plurality of tear tapes can be installed in the thread installation groove; the two ends of the tear tape are wedge-shaped; an opening groove is reserved between the tearing tapes.
Compared with the prior art, the utility model has the advantages of it is following: 1. the sectional tear tape is arranged in the thread mounting groove, so that the structure is favorable for ensuring that the electrical casing can be bent while the linear laying strength is ensured; 2. the flame-retardant layer is arranged in the outer pipe body, and the structure is favorable for ensuring that the electrical casing has flame-retardant capability when being directly arranged and bent.

Fig. 2 is a schematic partial sectional view of a flame retardant electrical casing.
Fig. 3 is a schematic view of a partial cross-sectional structure of a tear tape of a flame retardant electrical conduit.
In the figure: 1. an outer tubular body; 2. a flame retardant layer; 3. tearing the tape; 4. a connecting bridge; 101. a thread mounting groove; 102. a corrugated groove; 201. mounting grooves; 301. the slot is opened.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.
The specific implementation mode is as follows: as shown in fig. 1-3, the flame-retardant tube comprises an outer tube body 1, a flame-retardant layer 2, a tear tape 3 and a connecting bridge 4; the outer wall of the outer tube body 1 is provided with a thread mounting groove 101; the inner wall of the outer pipe body 1 is provided with a corrugated groove 102; the flame-retardant layer 2 is arranged in the outer tube body 1; the inner wall of the outer tube body 1 is clamped with the flame-retardant layer 2; connecting bridges 4 are arranged on two sides of the tear tape 3; the tear tape 3 is fixedly connected with the thread mounting groove 101 through a connecting bridge 4; a plurality of connecting bridges 4 are arranged at equal intervals on two sides of the tear tape 3; the flame-retardant layer 2 is provided with a mounting groove 201; a plurality of tear tapes 3 can be arranged in the thread mounting groove 101; the two ends of the tear tape 3 are wedge-shaped; an opening groove 301 is left between the tear tapes 3.
When the electrician's sleeve is used, as shown in the combined drawings of fig. 1-3, the electrician's sleeve with the required length is taken out and placed at the in-line laying position, because the tear tape 3 and the connecting bridges 4 at the two sides are arranged in the thread mounting groove 101, the outer wall of the electrician's sleeve is smooth and easy to lay, and the electrician's sleeve has good flame retardant capability and high strength; and when needs are crooked to be laid, tear tape 3 along thread mounting groove 101 from opening groove 301 department, make 3 both sides of tear tape connect bridge 4 and the disconnection of thread mounting groove 101, tear tape 3 suitable quantity, make 1 length enough bending of outer body after tearing be required shape, then can lay outer body 1 along the bending of required shape, it is more convenient when the bending is laid to make the electrician's sleeve pipe, simultaneously because install the fire-retardant layer 2 of outer body 1 inside and the thread mounting groove 101 combined action after the bending, make the electrician's sleeve pipe corner also possess stronger intensity and fire-retardant ability.
It is to be understood that the above-described embodiments of the present invention are merely illustrative of or explaining the principles of the invention and are not to be construed as limiting the invention. Therefore, any modification, equivalent replacement, improvement and the like made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. Further, it is intended that the appended claims cover all such variations and modifications as fall within the scope and boundaries of the appended claims or the equivalents of such scope and boundaries.
