Abstract

The utility model relates to a portable tightening apparatus for cable belts. The utility model comprises a fixed arm with a hook and a movable arm with a handle, wherein, a one-way stop sheet is arranged in a guide groove of the fixed arm, and a shifting sheet which drives a ratchet shell to rotate is arranged in a guide groove of the movable arm. A winding body with a cable belt clamping groove is fixed with the ratchet wheel into a whole. The utility model has the advantages of simple structure, convenient operation, safety, labor saving, and obvious tightening effect improvement, and effectively overcomes the disadvantages of binding looseness, etc., existing in the prior art.

Description

Portable strap tightener

The utility model relates to a kind of rope that restraint of loads uses or portable strap tightener of frenulum strained.

At present, rope or the frenulum used for Goods binding generally all adopt manpower tension or traditional pulley or stir the thick stick tension.Above-mentioned tension method is troublesome poeration, inconvenience not only, and binding is not tight, especially the goods on transport vehicle, if binding is not tight, and the serious consequence that will cause goods to scatter and disappear.

The purpose of this utility model provides a kind of portable strap tightener, and its simple in structure, easy operation, safe and reliable, laborsaving, tension effect significantly improve, and effectively overcomes shortcomings such as the binding that exists in the prior art is not tight.

The purpose of this utility model is achieved in that this device comprises and has deciding arm and having the swing arm of handgrip of hook, unidirectional locking plate is wherein arranged in deciding the arm guide groove, have in the swing arm guide groove to drive the plectrum that ratchet rotates, the coiling body and the ratchet that have clamping strap groove are loaded into one.

Because the utility model adopts moving, as to decide arm version, utilize be assembled in respectively moving, decide plectrum and unidirectional locking plate in the arm guide groove, driving pawl rotates, and drives the coiling body rotation, and the strap that inserts in the coiling body clamping strap groove is twined, reach the purpose of tension strap, so the operation not only simple in structure, easy of this device, and tension effect is very good, uses both safe and reliable, laborsaving again, guarantee tied cargo transportation security.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a kind of concrete structure scheme drawing of the utility model.

Fig. 2 is the cutaway view of Fig. 1 along the A-A line.

Describe concrete structure of the present utility model in detail according to Fig. 1-2.What this device comprised the swing arm 2 that has handgrip 1 and connector 3 and had a hook 12 decides arm 9, coiling body 6, ratchet 7, unidirectional locking plate 8, plectrum 4, anti-protection pad 10, frenulum parts such as (drawing among the figure).Wherein hook 12 is fixed on an end of connecting band 11, on the end axle that anti-protection pad 10 utilizes the other end of connecting band 11 to be sleeved on to decide arm 9.Can make swing arm 2 when swinging, avoid it to contact by anti-protection pad 10, prevent that goods is impaired with goods.Plectrum 4 utilizes retracing spring to be assembled in the guide groove of the chute of connector 3 and swing arm 2, and moves back and forth along chute and guide groove.Unidirectional locking plate utilizes retracing spring to be assembled in to decide in the arm guide groove, and moves back and forth along guide groove.Coiling body 6 has clamping strap groove, but clamping in the frenulum end insertion groove that needs to strain.The specification shape of groove should be determined according to the specification shape of frenulum.Ratchet 7 is loaded into one with coiling body 6, and ratchet rotates and drives the coiling body rotation.When swing arm 2 during around coiling body 6 rotational, plectrum 4 driving pawls 7 are in the time of rotational, and unidirectional locking plate synchronized operation prevents ratchet 7 backwards rotation, thereby guarantee that coiling body 6 can only unidirectional rotation, to the frenulum tension of reeling.

During use, the frenulum termination of restraint of loads is inserted in the coiling tank, hand taut frenulum, utilize the handgrip 1 on the swing arm 2 that swing arm 2 is swung around axle, crank motion driving pawl 7 by plectrum 4 rotates and drives coiling bodies 6 rotations, and strap is reeled on it apace, strains strap gradually.During the dismounting frenulum, as long as pull-up plectrum 4, make it to break away from ratchet 7 and place the positioning groove of deciding arm 9, meanwhile unidirectional locking plate also breaks away from ratchet 7 and places on the circumference of swing arm 2 (as shown in FIG.), can make the coiling body backwards rotation, unclamp the frenulum of coiling, frenulum is taken out from clamping frenulum groove.

Claims

1, a kind of portable strap tightener, comprise and have deciding arm and having the swing arm of handgrip of hook, it is characterized in that unidirectional locking plate is arranged in deciding the arm guide groove, have in the swing arm guide groove to drive the plectrum that ratchet rotates that the coiling body and the ratchet that have clamping strap groove are loaded into one.
