Description

A kind of two-way quick tightening device
Technical field
The present invention relates to rope band technique for tightening fields, more particularly to a kind of two-way quick tightening device.
Background technique
In terms of rope band tightening, there are many structure types both at home and abroad, general use receives the rope band mode of knotting It fastens, preferable tightening effect cannot achieve to rope in this way, reduced after in addition rope band knots using pulling force, exist certain Dangerous hidden danger, and when not needing tightening, rope band is difficult to unlock, and the recycling rate of waterused of rope band is very poor, and safety reduces, cost Relatively high, economy is bad, and is easy to be limited by external condition.
Summary of the invention
The purpose of the present invention is:
The present invention provides a kind of two-way quick tightening device for rope band tightening, is applicable to the two-way quick tightening of rope band.
The technical scheme is that
A kind of two-way quick tightening device, including firm banking 1, left tightening connector 2,3,2 torsional springs 4 of fixed pin and the right side Tighten connector 5.Wherein, firm banking 1 is rectangle ring body, is provided with a circular through hole in the intermediate up and down direction of firm banking 1, Left tightening connector 2 is provided with a circular through hole, the circular through hole phase of hole size and firm banking 1 close to right end up and down direction Together, left tightening connector 2 is equipped with an inclined-plane to front protrusion close to left end, has been covered with bumps on left 2 inclined-plane of tightening connector Uneven small triangle, right tightening connector 5 close to right end equipped with an inclined-plane to front protrusion, on right 5 inclined-plane of tightening connector Rough small triangle has been covered with it, left tightening connector 2 and right tightening connector 5 intersection are placed on firm banking 1, fixed Pin 3 sequentially pass through from bottom to top the following round hole of firm banking 1,1 torsional spring 4, left tightening connector 2, right tightening connector 5, 1 top round hole of another 1 torsional spring 4 and firm banking, left tightening connector 2, right tightening connector 5 and 2 torsional springs 4 are solid together It is scheduled on firm banking 1, by the effect of 2 torsional springs 4, compresses left tightening connector 2 and the inclined-plane of right tightening connector 5 respectively On on the inside of the 1 left and right ends rectangular edges of firm banking.
The beneficial effects of the present invention are:
Rope band tightening is integrated into a simple device by the present invention, is reduced costs, high reliablity realizes rope band Two-way quick tightening.Device is simple, and securely, high reliablity is easy to use, is not limited by external condition.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Fig. 2 is the schematic diagram in A-A direction of Fig. 1.
Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings:
As shown in Figure 1, 2, a kind of two-way quick tightening device, including firm banking 1, left tightening connector 2, fixed pin 3, 2 torsional springs 4 and right tightening connector 5.Wherein, firm banking 1 is rectangle ring body, is provided in the intermediate up and down direction of firm banking 1 One circular through hole, left tightening connector 2 are provided with a circular through hole, hole size and firm banking close to right end up and down direction 1 circular through hole is identical, and left tightening connector 2 is equipped with an inclined-plane to front protrusion, left 2 inclined-plane of tightening connector close to left end On be covered with rough small triangle, increase the rubbing action with cinch cord band, right 5 shape of tightening connector and left tightening company Fitting 2 is just the same, and the two can be used interchangeably, and left tightening connector 2 and right tightening connector 5 intersection are placed on fixation On pedestal 1, fixed pin 3 sequentially passes through the following round hole of firm banking 1,1 torsional spring 4, left tightening connector 2, the right side from bottom to top Connector 5,1 top round hole of another 1 torsional spring 4 and firm banking are tightened, by left tightening connector 2, right tightening connector 5 and 2 A torsional spring 4 is fixed on firm banking 1 together, by the effect of 2 torsional springs 4, makes left tightening connector 2 and right tightening connector 5 Inclined-plane be pressed on the inside of 1 left and right ends rectangular edges of firm banking respectively.
In use, pull open left tightening connector forward after rope band is entangled cargo, by rope band one end pass through firm banking with The gap that left tightening connector is formed, then decontrols left tightening connector, left tightening connector is acted on by torsional spring, utilizes wedge shape side Formula compresses rope band on the fixed base, and rope band can not free backward, can only pull out forward, by same method that rope band is another Tightly on the fixed base, rope band realizes cinch cord band by constantly pulling out forward to side pressure, so that rope band be allowed to fix cargo.Rope band Both ends may serve to cinch cord band, prevents from not tightening completely when fixed cargo too long using rope, also prevents rope band list To after tightening, the other end can not be unlocked when not in use.When needing to unlock rope band, it is only necessary to firmly hold rope band one end, together The tightening connector of this one end Shi Lakai, then unclamps rope band, and rope band passes through the big sky between tightening connector and firm banking Gap detaches backward, realizes the two-way quick tightening of rope band and frees, not by the environment shadow such as external shock or artificial collision It rings.
