Referring to Fig. 1, the retracting device 100 showing in the utility model first embodiment, including backrest 10 and retracting Mechanism 20.

The backrest 10 include support frame 11, set on 11 side of support frame two harnesses 12, be set to the support The support rod 13 of 11 other side of frame and the encircling band 16 being connected between two harnesses 12.The support frame 11 is by two Root vertical bar 111 and two cross bars 112 are spliced, and the both ends of the harness 12 are connect with two cross bars 112 respectively, described Support rod 13 includes horizontal part 131 and the vertical portion 132 being vertical on described 131 one end of horizontal part, the horizontal part 131 The other end is vertical with the cross bar 112 at the bottom to be connect.The encircling band 16 is equipped with grafting buckle 161, inserts when described When connecing 161 separation of buckle, the encircling band 16 is divided into two.In the specific implementation, the grafting buckle 161 can be using safety The buckle structure of band.

Wherein, the cross bar 112 is curved rod, and concave surface is towards the harness 12, in this way in backpack, the support frame 11 are more bonded the front of toter, bear more comfortable, laborsaving.

The furling mechanism 20 includes wheel rim 21, set on the rocking handle 22 of 21 side of wheel rim and set on the wheel rim The retracting bar 23 of 21 other sides.The wheel rim 21 includes outer portion 211, the bearing portion at the center of the outer portion 211 212 and the spoke portion 213 that is connected between the bearing portion and the outer portion 211, the outer portion 211 be fixedly arranged on institute On the top for stating horizontal part 131, the connecting pin of the rocking handle 22 is rotatably threaded through on the bearing portion 212, the retracting 23 one end of bar is fixedly connected with the connecting pin of the rocking handle 22, so as to will drive the retracting bar when rotating the rocking handle 22 23 rotate together.

In addition, the backrest 10 further includes a reinforcing rod 14, the both ends of the reinforcing rod 14 respectively with the institute that is in top Cross bar 112 is stated to connect with the top of the wheel rim.The end of the vertical portion 132 extends to the periphery with the wheel rim 21 simultaneously Outer portion 211 connect, be achieved the comprehensive fixation wheel rim 21, improve stability.

Further, the support rod 13 is equipped with far from one end of the support frame 11 for smoothing out with the fingers along to be furled band-like Two guide rods 15 of object, two 15 arranged for interval of guide rod, and two guide rods 15 are separately positioned on described On horizontal part 131 and the vertical portion 132, and it is each perpendicular to the support rod 13.The end outward bending of the guide rod 15 Extend a limiting section 151, the limiting section 151 is used to prevent the banding object of retracting from sliding from guide rod 15.Other In embodiment, the quantity of the guide rod 15 can also be increased or be reduced according to actual needs.

In the specific implementation, the body part of the retracting device 100 is in the case where meeting requirement, it is preferred to use The material of light weight makes, such as plastics or hollow aluminium alloy etc., it is ensured that the retracting device 100 has the excellent of light weight Point.

Referring to Fig. 2, this retracting device 100 is described in detail below for furling fire hose:

In use, can be first by 200 doubling of fire hose, then two harnesses 12 can be suspended on shoulder by fire fighter, and from The good grafting buckle 161 of grafting below, to allow encircling band 16 to be bundled on back, so that stable bear this retracting device 100 200 one end of fire hose (intermediate doubling position) is then wound on retracting bar 23 in advance, and separates fire hose 200 by front It seeks connections on two guide rods 15, then goes to rocking handle 22, so that fire hose is constantly wrapped on retracting bar 23, due to fire-fighting Water band 200 is sought connections on guide rod 15, and in coiling process, which can smooth out with the fingers fire hose 200 suitable, prevents from disappearing Water blocking tape 200 is knotted, is distorted, while the guide rod 15 additionally aids and squeezes away ponding remaining in fire hose 200, to After completing retracting, directly the water band 200 furled is extracted from retracting bar 23.

To sum up, the retracting device in the utility model above-described embodiment, using piggy-back structure, and structure is simple, matter Amount is light, burden that will not be excessive to fire fighter when bearing, uses and carry extremely convenient and at low cost, each is suitble to disappear Anti- vehicle configures one.

Referring to Fig. 3, it is shown the retracting device in the utility model second embodiment, the retracting dress in the present embodiment Set it is more or less the same with the retracting device in first embodiment, the difference is that, the retracting device still further comprises one Retracting set 30.

Retracting set 30 cooperates for being socketed with the retracting bar 23, and the retracting cover 30 and the retracting bar 23 it Between using anti-rotation cooperate.In the present embodiment, the retracting bar 23 is square pole, and the sleeve joint hole of the retracting set 30 is adaptation Square hole so that the retracting covers 30 can not the relatively described volume when retracting set 30 is sheathed on the retracting bar 23 It puts away sports equipment 23 rotations, but can be along the axial movement of the retracting bar 23, i.e., the described retracting, which covers 30, to extract from the retracting bar 23. In other embodiments, it can also be cooperated using other anti-rotations between the retracting set 30 and the retracting bar 23, such as Triangle cooperation, the cooperation of O shape, spline fitted, dovetail groove cooperation etc..

It should be understood that banding object has retracting resistance (such as drag and furl on the ground) due in retracting, cause band-like Object can retracting tightly be wound on retracting bar 23, after the completion of furling, entire bundle banding object extract it is difficult, even if extracting Afterwards, the banding object of retracting also can be loose.To solve the above-mentioned problems, spy's setting retracting covers 30 to the present embodiment, and specific effect is When furling banding object, retracting set 30 can be set on retracting bar 23, then furl banding object in retracting bar 23, this Sample retracting after the completion of, only need to extract retracting set 30, extract easily, and extract after will not be loose.

Further, the one end of the retracting set 30 is equipped with the stop section 31 of an annular, and the stop section 31 is by institute State retracting set 30 outer wall extend outwardly, the stop section 31 for prevent retracting when banding object from retracting set 30 It slides.

Above-described embodiments merely represent several embodiments of the utility model, the description thereof is more specific and detailed, But it should not be understood as limiting the scope of the patent of the utility model.It should be pointed out that for the common of this field For technical staff, without departing from the concept of the premise utility, various modifications and improvements can be made, these all belong to In the protection scope of the utility model.Therefore, the scope of protection shall be subject to the appended claims for the utility model patent.
