Abstract
A PVC pipe threading drag reduction protector comprises a metal short pipe connected with the pipe orifice of a wire box, wherein the outer diameter of one end of the metal short pipe is slightly smaller than the inner diameter of a PVC electric wire pipe, the metal short pipe is inserted into a wire outlet port of the PVC electric wire pipe, the edge of the other port of the metal short pipe is turned outwards to be in a horn mouth shape, and the turned outwards edge is clamped on the inner wall of the pipe orifice of the wire box. The utility model relates to a take nozzle stub of horn mouth inserts on the mouth of pipe of PVC electric wire pipe outlet port department, can guarantee in the threading, and belted wire iron wire and BV electric wire do not produce the friction with the PVC electric wire pipe, have reduced the resistance of construction from this, have improved the efficiency of work, make the threading both laborsaving, swift, can not destroy the mouth of pipe of being qualified for the next round of competitions again. The utility model provides a problem that band wire and end of a thread drop easily in traditional installation, avoided a large amount of manual works extravagant, can improve the efficiency more than one time.
Description
Technical field
The utility model relates to a kind of aid of wearing electric wire.
Background technology
In the building electric construction; dark pipe arrangement PVC conduit commonly used; this conduit operates simply; convenient; but when threading being installed in the later stage; because the pipeline of PVC conduit is long; it is many to turn round, and makes band line iron wire; the BV electric wire is through the situation of regular meeting's appearance with PVC conduit CONTACT WITH FRICTION, and strong friction not only produces heat; increase resistance; destroy the outlet mouth of pipe, and reduced the speed of threading, sometimes owing to overexert; also can make band line and wire lead drop out; at this moment, just must come out band line and pulling wire, wear the band line again; cause a large amount of artificial wastes thus, even have a strong impact on project progress.
The utility model content
In order to overcome the deficiencies in the prior art; the utility model provides a kind of pvc pipe threading drag reduction protector; solve in pvc pipe the big and easy ruined technical problem of the outlet mouth of pipe of threading construction resistance, and solve that threading speed is slow, problem that waste man-hour, band line and the end of a thread come off easily.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of pvc pipe threading drag reduction protector; it is characterized in that: comprise a metal short tube that is connected with the mouth of pipe of line box; one end external diameter of this metal short tube is slightly less than the internal diameter of PVC conduit; and be inserted in the outlet port of PVC conduit; the edge, another port turns up; be the horn mouth shape, flanging is stuck on the inwall at line box mouth of pipe place.
The external diameter of described metal short tube is 15mm-25mm, and length is 20mm-30mm, and wall thickness is 1mm-2mm.
The radius length of described metal short tube flanging cambered surface is not less than 3mm.
The beneficial effects of the utility model are as follows:
The utility model is one and is with bell-mouthed short tube, be inserted on the mouth of pipe of PVC conduit outlet port, can guarantee in threading, band line iron wire and BV electric wire do not produce friction with the PVC conduit, reduced the resistance of construction thus, improve the efficient of work, made threading both laborsaving, quick, can not destroy the outlet mouth of pipe again.The utility model has solved the problem of being with line and the end of a thread to come off easily in the conventional mounting process, has avoided a large amount of artificial wastes, can improve effect more than one times.
The mouth of pipe of the present utility model has been made outside horn mouth shape, can guarantee neither can destroy the outlet mouth of pipe and electric wire when threading, can avoid it to leak in the pvc pipe again.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of metal short tube.
Fig. 2 is the perspective view of metal short tube.
Fig. 3 is a mounting structure schematic diagram of the present utility model.
1-metal short tube, 2-flanging, 3-line box, 4-PVC conduit.
Embodiment
Embodiment is referring to shown in Fig. 1-3; this pvc pipe threading drag reduction protector; comprise a metal short tube 1 that is connected with the mouth of pipe of line box 3; one end external diameter of this metal short tube is slightly less than the internal diameter of PVC conduit 4; and be inserted in the outlet port of PVC conduit 4; the edge, another port turns up, and is the horn mouth shape, and flanging 2 is stuck on the inwall at line box mouth of pipe place.
The external diameter of metal short tube 1 is 15mm-25mm, and length is 20mm-30mm, and wall thickness is 1mm-2mm.
The radius length of metal short tube flanging 2 cambered surfaces is not less than 3mm.
Metal short tube 1 is installed on outlet port, the PVC conduit mouth of pipe, should take off when band bundle of lines the end of a thread takes the outlet mouth of pipe to.
