Abstract
The invention relates to a wire-protecting sleeve joint, belonging to the technical field of wire cable adaptors. The wire-protecting sleeve joint comprises a hollow joint body provided with an elbow, wherein the inner cavity of the elbow of the joint body is provided with a wheel axle and a roller wheel sheathed on the wheel axle. Since the inner cavity of the elbow of the wire-protecting sleeve joint is provided with the roller wheel, a wire cable can abut against the circumferential surface of the roller wheel when penetrating through the inner cavity of the elbow, and the roller wheel can be driven to rotate when the wire cable is pulled, so that rolling friction with small friction force is formed between the wire cable and the roller wheel; and thus, the wire cable can easily change in directions to pass through the wire-protecting sleeve joint, thereby providing great convenience for penetrating and arranging the wire cable into the wire-protecting sleeve in field, and facilitating subsequent wire replacement.
Description
Technical field
The present invention relates to a kind of wire bushing pipe joint that is used to install cable, belong to cable and connect the device technical field.
Background technology
The national standard of inside plant wiring requires with PVC protecting pipe and pipe joint cable to be carried out socket.The normally 90 degree turnovers of faying face that existing pipe joint (as elbow, threeway, four-way etc.) is inboard, cable in pipe joint when mobile resistance big, turn and just draw motionless cable when surpassing 3, time-consuming hard when not only laying cable for the first time, and be to change cable later on to bring very big difficulty.
At present, the way that the solution cable moves in the pipe joint inside turn in the practice generally has: one, reserve some Wire casing boxes in the wall or the ground separation at pipe joint place, making things convenient for cable to install, but so not only increase decoration cost, also can cause metope or ground not attractive in appearance; Two, an on-the-spot corner tube wall excision part with pipe joint with reduce lead by the time resistance, but so not only time-consuming, effort, and elbow intensity also can reduce greatly, bigger problem is a cement, sandstone etc. are easy to that the opening part from elbow enters in the pipe in construction, hinder passing through of lead; Three, on-the-spot with one section alternative pipe joint in protecting pipe bending back, but the general radius of bending back protecting pipe is bigger, if all imbed body of wall and ground, just need open very dark groove on the wall or ground is raised, except that increasing difficulty of construction, also influence the intensity of building structure like this; Four, also having a kind of medial surface of 90 degree corners of pipe joint is a bit of arc surface, as the disclosed a kind of cable conduct elbow of Chinese patent ZL200620053575.0, though the interior curved side of this elbow is also smaller than aforementioned tube joint slicker and more sly so that frictional resistance, but the friction of cable and interior curved side remains sliding friction, when cable repeatedly turns round when causing cable in the pulling to be pressed on this inner arc face, still can produce bigger frictional resistance, finally spur still unusual effort, time-consuming even draw motionless of cable.
Summary of the invention
The technical problem to be solved in the present invention is: a kind of wire bushing pipe joint with low frictional resistance is proposed, thus the convenient cable replacing of adopting after wire bushing is laid cable and laying.
Technical scheme of the present invention is: a kind of wire bushing pipe joint comprises hollow and is provided with the joint body of round part that the inner chamber of the round part of described joint body is provided with wheel shaft and is sleeved on roller on the wheel shaft.
Wire bushing pipe joint of the present invention is owing to the inner chamber at its round part is provided with roller, when passing the wire bushing pipe joint, cable abuts on the side face of roller, will drive roller when the pulling cable rotates, make cable and roller form the less rolling friction of frictional force, so cable can change the direction of motion very like a cork and pass through the wire bushing pipe joint.Compare existing various pipe joints, the not only convenient greatly on-the-spot laying cable that in wire bushing, installs, and be to change cable later on to bring very big facility.
Improvement of the technical scheme is: the middle part of described roller forms notch.Like this, can limit cable and on roller, laterally slide and the disengaging roller, remain cable and abut on the roller.
One of further improvement in the technical proposal is: described joint body is involutory two halves housing, is shaped on corresponding connector on the involutory surface of described two halves housing respectively; Described wheel shaft is divided into respectively two that inwall with the two halves housing is connected as a single entity.During installation, with the two halves housing to fashionable, roller with concave is placed in half housing earlier, and roller one end is enclosed within on the wheel shaft of this half housing, again the raised line and the groove respective aligned of two halves housing are pegged graft, simultaneously the roller other end is enclosed within on the wheel shaft on second half housing, on the involutory surface of two halves housing, is coated with a little adhesion agents at last and two halves housing firm engagement can be finished the installation of wire bushing pipe joint of the present invention.
Two of further improvement in the technical proposal is: the round part of described joint body is made two parts of loose joint each other, and a part is the basic shell that is connected as a single entity with joint body, and another part is the guard shield that can dock with basic shell sealing; Described roller is placed in the basic shell, and described basic shell has the biside plate vertical with the axial line of described wheel shaft, is shaped on the axis hole that is used to install wheel shaft on the described biside plate.
The one of perfect of technique scheme is: described connector is raised line and groove.
Perfect two of technique scheme is: described connector is a buckle.
Perfect three of technique scheme is: described connector is a snap ring.
Perfect four of technique scheme is: described connector is to prick silk.
Perfect five of technique scheme is: be shaped on the protection wheel shaft on the described guard shield and rotate unimpeded ear holder.
Further improving of technique scheme is: described joint body is one of elbow, threeway, four-way and Duo Tong.
