Abstract
The utility model provides an one -way guide pin bushing, include that one is used for the hollow base of threading cable and locks the hinge with the base through a plurality of that holds power spring hinge, the opening direction of locking hinge is all towards the cable, when the locking hinge rotates, hold the power spring produce one with rotation in the opposite direction's elasticity. The utility model discloses use the base for supporting, the locking hinge is locking device, when passing in the device is followed to rope, cable, can stir the locking hinge, makes the locking hinge hug closely the cable, and at this moment the cable passes from the forward, and the locking hinge is pushed aside by the resistance, when reverse passing was followed to the cable, frictional force can drive locking hinge towards rotation in the other direction, and the locking hinge is pressed the cable tighter, so, stimulate the cable toward reverse, one -way guide pin bushing just blocks tightly more, prevents the cable backward to pass through, thereby the problem of effectively solving the bellows, kick -backing when the cable cuts, simultaneously, the cable passes from this one -way guide pin bushing, puts in order the usefulness of doing of bunch cable in addition, makes the production process seem not in disorder.
Description
Technical field
This utility model belongs to mechanical fitting field, is specifically related to a kind of unidirectional guide pin bushing.
Background technology
When workshop workman cuts corrugated tube, cable by hand, it may appear that after just cutting off, it is local that tube head and the end of a thread retract to another under elastic force or gravity etc. disturb so that when workman cuts again, and needing moves one's steps gets back tube head.This can increase the work of workman, reduces production efficiency, and not yet has suitable frock to solve this problem at present.Automatic cutter relies on drive compression to overcome elastic force and gravity during cutting, and does not the most retrain the frock of corrugated tube, and once drive unclamps, and corrugated tube will eject at an arbitrary position, does not finds to solve very well the device of this problem at present.
Utility model content
The technical problems to be solved in the utility model is: provide a kind of unidirectional guide pin bushing, resilience when solution corrugated tube, cable cut, the in disorder problem of wire harness.
The technical scheme that this utility model is taked by the above-mentioned technical problem of solution is: a kind of unidirectional guide pin bushing, it is characterized in that: it include one for the base of the hollow of threading cable and with base by power spring hinged several locking hinges, locking hinge opening direction all towards cable；When locking hinge and rotating, power spring produces an elastic force contrary with rotation direction.
By such scheme, it is respectively provided on two sides with the positive stop of the anglec of rotation being fixed on base for limiting locking hinge at each locking hinge, wherein less with base angle positive stop is reverse block, the positive stop bigger with base angle is forward block, locks hinge and be close together with reverse block under naturalness.
By such scheme, described base is annular, and several described locking hinges are uniform along base circumference.
By such scheme, the described angle between reverse block and base is 10 to 20 degree, and the angle between forward block and base is 30-50 degree.
By such scheme, described locking hinge is 4.
By such scheme, described base edge connects fixed support.
The beneficial effects of the utility model are:
1, with base for supporting, locking hinge is locking device, when having rope, cable to pass from device, locking hinge can be stirred, locking hinge can produce an elastic force, make locking hinge be close to cable, at this moment cable passes from forward, and locking hinge is pushed aside by resistance；Cable is in time passing back through, and frictional force can drive locking hinge to rotate in the opposite direction, and cable is pressed tighter by locking hinge, maximum static friction force between cable and locking hinge becomes big, so, toward reversely pulling cable, unidirectional guide pin bushing just to block the tightest, effective stop cable back through；Thus effectively solve corrugated tube, cable problem of resilience when cutting, meanwhile, cable passes from this unidirectional guide pin bushing, the most whole bunch cable do use, make production process seem the most in disorder.
2, by practice, find that locking hinge needs more preferable with the cable structure effect that has a certain degree, therefore the positive stop of the anglec of rotation limiting locking hinge is set in locking hinge both sides.
3, this utility model reliability is high, production cost is low, it is possible to significantly improve Workshop Production work efficiency, and this utility model product structure is simple, service life length, spillage of material low, simple to operate, pollution-free.
4, by making the product of different size, it may also be used for the wire harness such as mouse lines, mobile phone charging wire arranges；Applied widely, use simple, effect obvious, the production of the people of great convenience, life.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model one embodiment.
Fig. 2 is the top view of Fig. 1.
In figure: 1-base, 2-locks hinge, 3-power spring, the reverse block of 4-, 5-forward block, 6-fixed support.
Detailed description of the invention
Below in conjunction with instantiation and accompanying drawing, this utility model is described further.
The present embodiment provides a kind of unidirectional guide pin bushing, as depicted in figs. 1 and 2, it include one for the base 1 of the hollow of threading cable and with base 1 by hinged several locking hinges 2 of power spring 3, the opening direction of locking hinge 2 is all towards cable；It is respectively provided on two sides with the positive stop of the anglec of rotation being fixed on base 1 for limiting locking hinge 2 at each locking hinge 2, wherein less with base 1 angle positive stop is reverse block 4, the positive stop bigger with base 1 angle is forward block 5, lock hinge 2 under naturalness to be close together with reverse block 4, when locking hinge 2 and rotating, power spring 3 produces an elastic force contrary with rotation direction.
Preferably, described base is annular, and several described locking hinges 2 are uniform along base circumference.For lock hinge 2 number, the present embodiment only as a example by 4, can with the thickness of sight line cable, base size depending on, cable is the thickest, locking hinge 2 number the most.
It is further preferred that the angle between described reverse block and base is 10 to 20 degree, the angle between forward block and base is 30-50 degree.Practice have shown that, when cable centerline line and locking hinge plane angulation are between 50-70, clamping effect is best, for ensureing using effect, forward link stopper makes in hinge rotary course, angle limits between hinge plane and annulus base transversal plane is below 45, and reverse block ensures that angle is more than 15.In the present embodiment, the angle between reverse block and base is 15 degree, and the angle between forward block and base is 45 degree.
Further preferred, described base edge connects fixed support 6, fixing for base.
This unidirectional being enclosed within does not affects outside normal forward traction corrugated tube, cable, rope, can effectively stop its resilience.Make different size and can be additionally used in the arrangement of the wire harness such as mouse lines, mobile phone charging wire.This unidirectional guide pin bushing is applied widely, it is simple to use, effect is obvious, the production of the people of great convenience, life.
