Abstract
The invention relates to a cable-protecting sleeve joint and belongs to the technical field of cable adaptors. The cable-protecting sleeve joint comprise a hollow joint body provided with a bend portion. The cavity of the bend portion of the joint body is provided with a wheel axle and a rolling wheel sleeved on the wheel axle. Because the cavity of the bend portion of the cable-protecting sleeve joint is provided with the rolling wheel; when penetrating through the cavity, the cable is abutted against the peripheral surface of the rolling wheel; when the cable is drawn, the rolling wheel is driven by the cable to rotate, and rolling friction with small friction force is formed between the cable and the rolling wheel; therefore the cable can easily change motion directions and penetrates through the cable-protecting sleeve joint; accordingly penetrating and wiring of a spot cable can be very conveniently conducted in the cable-protecting sleeve; and later, cable can be conveniently changed.
Description
The application divides an application.The applying date of original application is on March 16th, 2010, and application number is 201010147797.X, and denomination of invention is bushing joint.
Technical field
The present invention relates to a kind of bushing joint for the installing 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 socketed.The normally 90 degree turnovers of faying face that existing pipe joint (as elbow, threeway, four-way etc.) is inboard, when cable moves in pipe joint, resistance is large, turn and just draw motionless cable when surpassing 3, time-consuming hard when not only laying cable for the first time, and bring very large difficulty for changing later on cable.
At present, solving the way that cable moves in the pipe joint inside turn in practice generally has: one, wall or the ground separation at the pipe joint place reserves some Wire casing boxes, facilitating 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 wire by the time resistance, but so not only time-consuming, the effort, and elbow intensity also can reduce greatly, larger problem is cement, sandstone etc. are easy to that the opening part from elbow enters in pipe in construction, hinder passing through of wire; Three, the scene is with one section rear pipe joint that substitutes of protecting pipe bending, but after bending, the general radius of protecting pipe is larger, if all imbed body of wall and ground, just need to open on the wall very dark groove or ground is raised, also affect like this intensity of building structure except increasing difficulty of construction; Four, also having a kind of 90 medial surfaces of spending the corner of pipe joint is a bit of arc surface, a kind of Wire conduit bend as disclosed in Chinese patent ZL200620053575.0, although the interior curved side of this elbow is also smaller than the rounder and more smooth so that frictional resistance of above-mentioned pipe joint, but the friction of cable and interior curved side remains sliding friction, when cable repeatedly turns round when causing cable in pulling to be pressed on this inner arc face, still can produce larger frictional resistance, finally pull cable still very the effort, time-consuming, even draw motionless.
Summary of the invention
The technical problem to be solved in the present invention is: a kind of bushing 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 bushing joint, and comprise hollow and be provided with the joint body of round part, the inner chamber of the round part of described joint body is provided with wheel shaft and is sleeved on roller on wheel shaft.
Bushing joint of the present invention is because the inner chamber at its round part is provided with roller, when passing bushing joint, cable abuts on the side face of roller, will drive roller when 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 bushing joint.Compare existing various pipe joints, not only greatly convenient scene installs the laying cable in wire bushing, and brings very big facility for changing later on cable.
Improvement of the technical scheme is: the middle part of described roller forms notch.Like this, can limit cable and laterally slide on roller and break away from roller, remain that cable abuts on roller.
One of further improvement in the technical proposal is: described joint body is involutory two halves housing, is shaped with respectively corresponding connector on the involutory surface of described two halves housing; Described wheel shaft is divided into respectively two that inwall with the two halves housing is connected as a single entity.During installation, when the two halves housing is involutory, first the roller with concave is placed in half housing, and roller one end is enclosed within on the wheel shaft of this half housing, again 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, is coated with a little adhesion agents at last on the involutory surface of two halves housing and can with two halves housing firm engagement, completes the installation of bushing 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 basic shell, and described basic shell has the biside plate vertical with the axial line of described wheel shaft, is shaped with on described biside plate for the axis hole that wheel shaft is installed.
The one of perfect of technique scheme is: described connector is raised line and groove.
Perfect two of technique scheme is: described connector is buckle.
Perfect three of technique scheme is: described connector is snap ring.
Perfect four of technique scheme is: described connector is tied silk.
Perfect five of technique scheme is: be shaped with the protection wheel shaft on 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.
