Description

The stretcher structure of collapsible location

Technical field

The utility model relates to bicycle structure, particularly the stretcher structure of bicycle.

Background technology

Bicycle is except that can be used as the instrument use of riding instead of walk, more there are more and more many people will be used as the outdoor leisure activity by bike, and for bicycle being carried easily or collecting, promptly there is the dealer to develop the Folding Bicycle that vehicle frame and stretcher can be folded, dwindle and the bicycle overall volume can be folded as far as possible, so that carry or collect.

See also Fig. 1, Fig. 2, shown in Figure 3, it is No. 092206332 " stretcher structure " novel patent case of TaiWan, China application, it mainly includes pedal body 10, crank shaft piece 11, movable block 12, sealing piece 13 and spring 14, described pedal body 10 is to be horse-hof shape, its inboard offers ㄇ shape groove 101, and sets up opposed two cambered surfaces 102 separately in the both ends open desired location of described ㄇ shape groove 101; The front end of described crank shaft piece 11 be provided with can with the Fixed Division 111 of crank connecting link, and be respectively equipped with the jack-post 112 of tool bulge loop 113 in both sides, for cambered surface 102 places that slip into pedal body 10, the both-side ends of described crank shaft piece 11 forms embeded slot 114 respectively in addition, and the above and below of both sides then is respectively equipped with arcuation guide surface 115; 12 groups of described movable blocks are located in the ㄇ shape groove 101 of pedal body 10, the both sides of described movable block 12 are respectively equipped with blocking part 121, in the embeded slot 114 that penetrates

crank shaft piece

11, and and 10 of pedal bodies wear a spring 14, for shoring movable block 12; In addition described two sealing pieces 13 are that compacting is cemented in the ㄇ shape groove 101 of pedal body 10, and at one end are provided with the arcuation closing portion 131 with jack-post 112 closings of crank shaft piece 11, promptly are combined into described stretcher structure; When described stretcher was received whole pedal body 10 in turnover, it was that compacting movable block 12 contracts backward and moves earlier, and made the blocking part 121 of movable block 12 break away from the embeded slot 114 of build-in crank shaft pieces 11, can be with upwards turnover of pedal body 10; And when using stretcher, it is with outwards light group of pedal body 10, two blocking parts 121 of described movable block 12 and guide surface 115 guidings that rely on crank shaft piece 11, simultaneously with movable block 12 compression springs 14, and when replying to horizontality, described spring 14 is promptly shored movable block 12, so that two blocking parts 121 of movable block 12 penetrate in the embeded slot 114 of crank shaft piece 11 again, and fix, and then make pedal body 10 reply running condition with crank shaft piece 11 clips; Yet, though described stretcher can be easy to gently dial pedal body 10,, still have following scarce fraud in the use to reply running condition:

Described pedal body 10 is when the turnover receipts are whole, two blocking parts 121 of described movable block 12 are only to push up on the plane that the guide surface 115 of pulling at crank shaft piece 11 extends forward, so that two blocking parts 121 of described movable block 12 can utilize guide surface 115 guidings of crank shaft piece 11, though it can be easy to pedal body 10 is replied running condition, make equally that but 12 two blocking parts 121 of described movable block are difficult to crank shaft piece 11 is done actv. clip location, and then cause and to guarantee to turn down the awkward situation of receiving whole stretcher.

Because the arcuation closing portion 131 of the cambered surface 102 of described pedal body 10 and sealing piece 13 only is resisted against on 112 sections anchor rings of jack-post of crank shaft piece 11, bulge loop 113 places of described jack-post 112 but do not have any against, and fail jack-post 112 and bulge loop 113 are done complete coating closing, make when described pedal body 10 turns down, promptly easily produce and rock, and then pedal body 10 and crank shaft piece 11 can't be done firm binding.

The embeded slot 114 of described crank shaft piece 11 is when making moulding, because in the manufacturing process, the influence of the contraction of its material itself and the various factors such as pattern draft of forming mould, to make the width dimensions of described embeded slot 114 open ends greater than the width dimensions of bottom, and when the blocking part 121 of described movable block 12 penetrates the embeded slot 114 of crank shaft piece 11,121 of the open end of described embeded slot 114 and blocking parts promptly produce the gap of rocking, and then make pedal body 10 can't stablize the clip location.

In view of this, the utility model designer then is engaged in the research and development and the making experience of relevant industries for many years with it, at the present problem in-depth study that faces, through the research of long-term endeavour with study, grind the stretcher structure of creating a kind of collapsible location eventually, and significantly to improve the scarce fraud of prior art, this is design aim of the present utility model.

Summary of the invention
