Abstract

The utility model provides a tightening device which is used for binding cargoes. The utility model is characterized in that the tightening device is composed of a ratchet shaft, a frame and a plate arm; the frame and the plate arm are hinged at both sides of the ratchet shaft, the middle of the ratchet shaft is provided with chemical fiber belts and gaps are arranged between the chemical fiber belts; the both sides of the ratchet shaft is fixedly provided with two ratchet wheels; the frame and the plate arm are respectively provided with a telescopic ratchet pawl. The utility model has the advantages of simple structure, sturdy binding, uniform application of force, high binding speed, time saving and labour saving.

Description

Tightening device

The utility model relates to a kind of goods transport binding utensil, is a kind of fastener.

At present, restraint of loads is adopted light and chemical fibre band that stretching resistance is strong bundlees acarpous rope with the heaviness that replaces original use more and more on the transportation means at home and abroad.But, often easily cause Goods binding not firm because of the chemical fibre band is difficult for knotting and easily loosening knotting.

The purpose of this utility model provides a kind of chemical fibre band fastener, and it replaces manpower to the binding of goods, the work of tying tight and tie a knot with simple machine, saves time to reach, laborsaving and bundle solid purpose.

The purpose of this utility model be achieved in that because of this fastener be to use chemical fibre band design-calculated, therefore, it comprises the chemical fibre band when using, the keystone configuration characteristics of this fastener are: it is by ratchet shaft, framework and remove arm and form, framework and remove the both sides that arm is hinged on ratchet shaft, wherein on ratchet shaft, fix two ratchets, have the slit of wearing the chemical fibre band in the middle of the axle, and framework has telescopic ratchet respectively with removing on the arm.

Narrate embodiment according to accompanying drawing below.

Fig. 1 is the front view of fastener.

Fig. 2 is the birds-eye view of Fig. 1.

Running condition figure when Fig. 3 wears the chemical fibre band for fastener.

Shown in Fig. 1-2: ratchet shaft 1 can adopt by two semicircles and constitute, and can adopt again in the centre of an axle, leaves a strip hole form along axis, its objective is can produce slit 2 in the middle of making axle 1, so that from then on the chemical fibre band is passed in the slit.Two ratchets 3 are fixed in ratchet shaft 1 both sides.The front portion of framework 4 is hinged on the axle 1, and is positioned at the inboard of two ratchets 3.All have chute 5 on the biside plate at framework 4 middle parts, the left and right sides of board-like detent 6 just is inserted in the chute 5, and to keep it to stretch out the chute outside be the distance of a ratchet thickness.Like this, be to contact with ratchet 3 with regard to making the ratchet that is positioned at this board-like front end in the biside plate outside of framework 4, the width of hinge around the chemical fibre band then stayed in the biside plate inboard.Have spring 7 in the rear end of board-like ratchet 6, spring 7 is enclosed within on the caudal peduncle of ratchet 6 rear ends, and is inserted in by this caudal peduncle in the jack on the spring perch 8 that is connected as a single entity with framework 4, makes spring 7 fixing.Like this, board-like detent can only be done telescopic action along the chute track under action of the spring.The rear portion of framework 4 is a chemical fibre band anchor shaft 9, and axle 9 can be enclosed within the chemical fibre band on the axle by its screw-rod structure, and the effect of firm framed structure is also arranged simultaneously.

The front portion of removing arm 10 is hinged on the ratchet shaft 1, and is positioned at the outside of two ratchets 3, for preventing its axial motion, is fixed with pivot pin 11.The two side arms of removing the arm middle part also is provided with chute 12, and what slide in chute 12 is board-like two ends, the left and right sides of stirring ratchet 13.The board-like ratchet 13 front end both sides of stirring contact with two ratchets 3, and the indent gap is left in the centre, so that coiling chemical fibre band.The board-like middle band pin-and-hole 14 of ratchet 13, pin-and-hole 14 is inserted with of torsion spring 15, and the other end of torsion spring is fixed on removes on the arm 10.The rear portion of ratchet 13 is a pull handle 16, and pull handle 16 is to stamp out the rectangle handle on the same block plate of ratchet 13.At the rear portion of removing arm 10 are handles 17.To remove the arm integral structure firm in order to make, and is provided with pivot shaft 18 between the two side arms of removing arm 10.In order to unclamp fastener, make detent 6 withdraw from the teeth groove of ratchet 3 earlier, be provided with camming surface 19 structures at the front end of removing arm.

As shown in Figure 3: during use, fastener connects with the chemical fibre band that is fixed on something by anchor shaft 9, to need fastening chemical fibre band to pass slit 2 on the ratchet shaft again, just can spur handle 17 up and down, make the ratchet of removing on the arm of stirring stir the ratchet rotation, be inserted in the middle chemical fibre band of axle around the axle coiling thereby allow.Because of the stopping function of detent is arranged, even if ratchet is reversed, till tightly wrapping.If fastener is unclamped, will remove the big corner of arm earlier, make its camming surface 19 push up back detent 6, turn round and stretch out the hand handle 17 with pulling again, just can become flexible.

The utility model is simple in structure, the solid and uniform force application of restraint of loads, and binding speed is fast, saves time again, laborsaving.

Claims

1, a kind of fastener, it comprises the chemical fibre band when using, it is characterized in that: this fastener is by ratchet shaft, framework and remove arm and form, framework and remove the both sides that arm is hinged on ratchet shaft, wherein on ratchet shaft, fix two ratchets, have the slit of wearing the chemical fibre band in the middle of the axle, and framework has telescopic ratchet respectively with removing on the arm.

2, fastener according to claim 1 is characterized in that: have the ratchet shaft of wearing chemical fibre crack with seam, promptly can adopt the two halves circular shaft to constitute, can adopt the form of leaving strip hole in the middle of an axle again.
