Description

The twirl device of winch tape spool

Technical field

The invention belongs to field of mechanical technique, the binding tools of using on particularly a kind of automobile.

Background technology

In vehicular transport goods process, goods needs binding usually, comes off when the running car or collides mutually and cause and lose or damage to prevent goods.Though the mode that directly bundlees with rope is in daily use, and wastes time and energy, and is difficult to the goods tighten.

Winch is a kind of advanced person's a binding tools.Adopt not only convenient but also safety of winch restraint of loads, be subjected to the welcome of vast chaufeur deeply.As shown in Figure 5, a support 4 and tape spool 3 are arranged on winch, tape spool 3 is loaded on the support 4, and can rotate.The bundling belt of bundled device is on tape spool 3.By rotating tape spool 3, the bundling belt that is tied on the goods is tightened up, just Goods binding can be got up.

The method that existing rotation tape spool 3 tightens up bundling belt is the crow bar hole 9 of a crow bar being inserted tape spool 3 one ends, pulls crow bar, and tape spool 3 is rotated.Because winch is fixed on the car body, be subjected to position limit, in operating process, after pulling crow bar and making tape spool 3 rotating certain angle, must transfer to crow bar to insert another crow bar hole 9, so that be rotated further tape spool 3.

Obviously, operation effort like this is time-consuming.Simultaneously, because crow bar is transferred to and insertion, cause the damage of human finger or other position easily.

Summary of the invention

To the objective of the invention is in order addressing the above problem, the twirl device on a kind of winch tape spool to be provided, it will not transferred to by crow bar when operation, thereby easy to operate, laborsaving, the binding speed of raising winch is guaranteed the safe and reliable of operating process.

Purpose of the present invention can realize by following technical proposal: the twirl device of this winch tape spool is arranged at the zone axis extension end of winch bracket sidepiece, it is characterized in that, this device comprises a permanent seat and a rotor, permanent seat and tape spool are fixed together, rotor is socketed on the sidepiece of permanent seat, and be provided with a single-way linkage mechanism at the contact surface place of permanent seat and rotor, at least one crow bar hole is arranged on rotor.

In the twirl device of above-mentioned winch tape spool, described single-way linkage mechanism comprises several spring eyes on the rotor that is positioned at rotor and permanent seat contact surface place, a spring and a fore-set all are housed in each spring eye from the inside to the outside, fore-set under the effect of spring roof pressure in the sidepiece of permanent seat, sidepiece at permanent seat is provided with and the cooresponding chute of spring eye equal number and position, a side of chute be one along the rotor rotation direction to lopsidedness and extend to the inclined-plane on fixed seat side surface, another side is facing directly perpendicular to the fixed seat side surface.

In use, when when chute inclined-plane bevelled direction is rotated rotor, the fore-set that stretches out spring eye under action of the spring can move up along the inclined-plane of chute, make in the fore-set retraction spring eye, until the fore-set roof pressure on the side surface of permanent seat.Then, fore-set enters in the next chute, repeats this process again.Obviously, when this direction was rotated, permanent seat was fixed, that is to say that rotor can not drive tape spool and rotate at rotor.

Otherwise if rotor is rotated in opposite direction, then after fore-set entered chute, fore-set can be blocked by facing directly of chute, thereby fore-set can't slip over chute, and like this, rotor and permanent seat become interaction relation.Under the rotating torque effect of rotor, permanent seat also rotates together, drives tape spool at last and rotates.

When this wheel word was applied to winch, the direction of the rotation direction of rotor and the winding of winch tape spool was consistent when rotor was linked with permanent seat.In use, as long as crow bar is inserted in the crow bar hole of rotor, pull crow bar back and forth repeatedly.Owing to can only make permanent seat along unidirectional rotation, bundling belt be tightened up so can drive tape spool.Finish using, transfer to crow bar to get final product.

Directly insert the mode of tape spool end with crow bar in the prior art and compare, after winch adopts this wheel word, in the whole operation process, will not transfer to by crow bar, safe and reliable and laborsaving, can not cause damage to product or human body.Simultaneously, the amplitude of the pulling size of crow bar is also without any restriction, uses very conveniently, improved the binding speed of winch, has higher utility.

The specific embodiment

As shown in Figure 1, the twirl device of this winch is arranged at tape spool 3 external parts of winch bracket 4 sidepieces.This device comprises a permanent seat 1 and a rotor 2.Tape spool 3 is loaded on the support 4 of winch, and can rotate.In use, be wound with bundling belt on the tape spool 3.Permanent seat 1 is fixed together with tape spool 3.

Rotor 2 is socketed on the sidepiece of permanent seat 1.In the present embodiment, be provided with a locating plate 10 between rotor 2 and permanent seat 1, after rotor 2 is placed in permanent seat 1, block rotor 2 by locating plate 10, locating plate 10 is fixed on the permanent seat 1 by screw 11.Adopt such structure, make rotor 2 can not break away from permanent seat 1, and rotor 2 can rotate with respect to positioning seat 1.

In the present embodiment, two crow bar holes 9 that are used for inserting crow bar are arranged on rotor 2, these two crow bar holes 9 communicate.

As Fig. 2, Fig. 3 and shown in Figure 4, five chutes 5 are arranged on permanent seat 1, chute 5 is uniformly distributed in the sidepiece of permanent seat 1.A side of chute 5 is inclined-plane 51, and another side is for facing 52 directly perpendicular to permanent seat 1 side surface.Chute inclined-plane 51 along rotor 2 rotation directions to lopsidedness and extend to permanent seat 1 side surface.

As shown in Figure 1, five rectangular distributions and position and chute 5 corresponding spring eyes 6 are arranged also on rotor 2, a spring 7 and a fore-set 8 all are housed in each spring eye 6 from the inside to the outside.The undersized of fore-set 8 is in the size of chute 5, and fore-set 8 can insert in the chute 5.When rotor 2 turn to spring eye 6 and chute 5 over against the position time, fore-set 8 inserts in the chutes 5 under the effect of spring 7.

Obviously, if rotor 2 is when 51 bevelled directions are rotated along the chute inclined-plane, fore-set 8 can move up along the inclined-plane 51 of chute 5, until fore-set 8 roof pressures on the side surface of permanent seat 1.If make rotor 2 along counter-rotation, then fore-set 8 52 is blocked and can't slip over chute 5 by facing directly of chute 5.At this moment, rotor 2 becomes interaction relation with permanent seat 1, can drive tape spool 3 and rotate.

When coming back rotation rotor 2, can only make permanent seat 1 unidirectional rotation.Therefore,, pull crow bar repeatedly, just can drive tape spool 3 and tighten up bundling belt when crow bar being inserted crow bar hole 9.
