Specific embodiment

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

With reference to shown in Fig. 1-Fig. 7, this automatic band-retracting vehicle safety tensioning device mainly includes handle, enwinding spring axis 17, receives Tep reel, take-up device, detent component, knob 15, ribbon 26 etc., wherein：

The handle includes the left and right lateral plate 2 of structure identical, and two lateral plates 2 are linked into an integrated entity by several connecting shafts 4.Handss The rear portion of handle is coated with involucrum, is beneficial to hand-held and increase comfortable feel degree.Involucrum is by the lower cover 10 of lid on one 11 and mutually knot Couple integral by screw 12 and the class connector of rivet 13 after conjunction, and the top of upper lid 11 is additionally provided with an opening 111, so that dress Button 8 on detent 7 is exposed at outside.In addition a hook-like hook 3 is connected between the afterbody of left and right lateral plate 2, The hook of hook 27 being available on ribbon is held.

The machine reel is integrally formed by biphase isostructural ratchet 22 by a reel 23, and two ratchets 22 are separately fixed at The two ends of reel 23, the opening 231 for having an axial direction on reel 23 can make the ribbon 26 being connected on enwinding spring axis 17 from the opening 231 pass.The enwinding spring axis 17 is rotatably connected to two lateral plates 2 of handle through machine reel, and axle and axis hole it Between be provided with axle sleeve 16.

The knob 15 and take-up device are respectively provided at the outside of the left and right lateral plate 2 of handle, are connected to enwinding spring axis 17 overhanging In two axial ends.Wherein take-up device is the recovery that ribbon 26 is automatically obtained using wind spring 19, and it is mainly by (the clockwork spring bullet of wind spring 19 Spring), jump ring 18 and the assembling of coil spring box 20 constitute, be wherein arranged in coil spring box 20 after the warp of wind spring 19, and the wind spring 19 is anti- An outboard end after volume is plugged and is positioned in the locating slot of box, and a reverse medial extremity then wears the groove for being positioned at enwinding spring axis 17 It is interior.Coil spring box 20 is fixed on the lateral plate 2 of handle by screw 21.

The knob 15 is fixed on the other end of enwinding spring axis 17, can directly drive enwinding spring axis 17 to rotate by it, to meet The needs that ribbon 26 is further tightened up.The outside of knob 15 is equipped with trim 14.

The detent component includes detent 7, spring 6 and button 8, and wherein detent 7 passes through thereon Two sides are movably inserted in the respective aperture of left and right lateral plate 2, and the rear portion of detent 7 has extension pin to be available for spring 6 to be arranged. A catch 5 is fixed between two lateral plates 2 of handle, is available for pin to pass through.And the crown of spring 6 one on pin is enclosed within stop spine On pawl 7, other end is withstood on catch 5, makes detent 7 prop up ratchet 22 by spring force, is placed restrictions on machine reel and is rotated clockwise. Button 8 is fixed on detent 7 by screw 9, can drive the action together of detent 7, i.e., backward promoting button 8 when, only Pawl 7 also departs from ratchet 22 therewith moving afterwards together, and now machine reel is free to rotate.When release button 8, detent 7 reply under spring force, prop up ratchet 22 again again.

The ribbon 26 dresses up one with the machine, and one head is connected with enwinding spring axis 17, other end opening from following reel Mouth 231 is drawn to retread and is passed down through the stop collar 25 for being located at handle leading section.The stop collar 25 is filled by upper and lower two connecting shafts 24 on handle, and ribbon 26 is passed through from the hole of two between centers, below a connecting shaft 24 axial line less than being located at wind spring behind The axial line of axle 17.This stop collar 25 is played and ribbon 26 is oriented to and spacing effect, prevents ribbon crooked.This ribbon 26 is in volume When spring axle 17 is rotated clockwise, ribbon release；Otherwise then ribbon is reclaimed, on reel 23.

The ribbon of needs, this take-up device is used there are different connected modes according to difference, as shown in Fig. 1-Fig. 7 Take-up device, its ribbon 26 only have single ribbon, ribbon 26 from stop collar 25 through it is rear by its link up with 27 can hook hold from On the hook of handle afterbody.It is another kind of as shown in figure 8, have two ribbons, long ribbon 28 is connected on enwinding spring axis 17, from spacing Set 25 is drawn, and short ribbon 30 is connected in a fixing axle 29 of handle afterbody.This kind of mode is to eliminate hook, in handss Handle tail fills a fixing axle.

In conjunction with shown in Fig. 6, Fig. 7.To the completely as follows using process of this take-up device：

When pulling out 26 fixed object of ribbon, promoting button 8 backward first, make to move after detent 7 and depart from ratchet 22, Now machine reel is free to rotate.Therefore during ribbon is pulled out, machine reel and enwinding spring axis also together with along clockwise direction Rotate.And wind spring 19 also begins to pretension storage roll power while enwinding spring axis 17 is rotated, as shown in Figure 7.

After fixing goods, button 8 is pushed backward, wind spring 19 starts release volume power, drives enwinding spring axis 17 and machine reel edge Rotate in an anti-clockwise direction, so as to automatic tightening ribbon.After automatic tightening ribbon, release button 8, detent 7 is in spring force The lower reach of effect is engaged with the ratchet 22 on machine reel ratchet, by machine reel locking, as shown in Figure 6.Tighten up if desired for bigger Power, can continue on counterclockwise twisting knob 15, ribbon 26 is received tighter and tighter.

After the completion of operation, it is possible to carry article.

During release (ungirding), button 8 is pushed backward, detent 7 is separated with ratchet 22, pull out ribbon 26.

And this utility model can also have different modifications or improvement in addition to the description of above-described embodiment, and it is not limited to This.For example handle can also adopt the structure of left and right lateral plate disjunctor；Stop collar includes that its structure and mounting means can be made to become Change, the structure being connected with lateral plate is directly set such as on stop collar, and without connecting shaft.
