Description

But collapsible type pedal

Invention field

But the utility model relates to a kind of collapsible type pedal, refers to a kind of quick-disassembly structure of being made up of adapter and pedal axle center especially.

Background technology

Because the rapid transition of environment make Sport ﹠ Casual place and space face wretched insufficiency at present, especially the Regular Bicycle fan often suffers from no suitable athletic ground, and needs with vehicle carrying bicycle to outdoor, to satisfy the enjoyment that it drives.

For making things convenient for the portable delivery of vehicle, except utilization Regular Bicycle portable frame auxiliary fixing, popular on the market Folding Bicycle, little and do not take up space because of volume after folding, so favored by many people; But, no matter whether bicycle is foldable structure, its vehicle frame two side pedals are owing to having the characteristic of pivot and stretching to two pleurapophysis respectively, no matter keep flat or upright state so vehicle frame adopts, all will cause the obstruction in the storing or produce not steady phenomenon, and, be difficult to dismounting as if no speciality tool because the axle center of general pedal is that directly locking is positioned on the crank, and assembling also quite is not easy, thereby makes this phenomenon slowly be difficult to be resolved.

Present pedal structure has multiple different pattern and function, can select collocation for use for the customer, but because general pedal assembly and disassembly is difficult for the dismounting and change voluntarily so Chang Wufa follows one's bent; Existing collapsible bicycle pedal all has its special structural design; Therefore at package assembly and the change existing many disappearances of folding mode and the drawback of existing pedal, remain to be improved.

Summary of the invention

But in view of this utility model proposes a kind of collapsible type pedal, but should be formed by adapter and pedal axle center by the collapsible type pedal, after making this adapter be locked in crank, not only can make pedal assemble quickly and easily, dismantle and fold, to improve packaging efficiency and to dismantle easily and take in, also can guarantee simultaneously the smoothness that pedal rotates, and can supply with various car type, comprise mountain-climbing car, sport car, city car, folded bicycle that Regular Bicycle is used, even cycling-trainer is all applicable, thereby makes whole really tool innovation practical effect.

Thus, but main purpose of the present utility model is to be to provide a kind of collapsible type pedal, but should the collapsible type pedal be to set up one by place, pedal axle center can supply the adapter of simple and easy stopper socket, the structure design that can lock mutually with crank simultaneously by the first terminal bolt portion that transfers, after can making adapter be fixed in crank, can provide the fast and convenient assembling of pedal, dismounting and folding.

The utility model is compared prior art, really can obtain following some advantages:

1, assembly and disassembly is fast and convenient: because adapter of the present utility model can lock mutually with crank, and passing by stopper ring on it, can be easily and the mutual assembly and disassembly in pedal axle center, so make pedal can realize easyly assembling apace, dismantling and folding effect.

2, can guarantee the smoothness of pedal frame commentaries on classics: because the sleeve pipe of the utility model adapter and pedal shaft are formed with the ball and ring pearl groove structure of mutual lift-over location in the heart, so can use the smooth and easy pivot of guaranteeing after pedal is assembled.

3, the pedal of pulling down does not separate with crank, can take back crank at any time, does not influence the function of trampling, and is consistent with general folding step function.

The specific embodiment

See also Fig. 1 to shown in Figure 4, but be a kind of collapsible type pedal, it mainly includes a pedal 10 and an adapter 20; Wherein

Pedal 10, its axle center 11 ends are formed with a shape Plug Division 111, and 111 appropriate locations are formed with a ring pearl groove 111a in the Plug Division;

Adapter 20, comprise a sleeve pipe 21, these sleeve pipe 21 outsides are extended with a bolt part 212 than path, and the inboard sleeve part 213 than path that is extended with, sleeve part 213 external diameter edge appropriate locations then are arranged circumferentially some pearl groove 213a that are embedded with ball 22, and what a sheathed side was resisted against switching portion 211 lateral margins on sleeve part 213 shores spring 23, the stopper ring 24 of a sheathed end tool spring tank 241 on sleeve part 213 again, spring tank 241 just can be covered in shoring spring 23 outsides, the bottom land edge 242 of spring tank 241 then can compress in good time shores spring 23, the internal diameter edge of stopper ring 24 also can be in good time and the ball on the sleeve part 213 22 compress mutually or break away from, between sleeve part 213 and bolt part 212, be embedded a clasp 25 again, for location stopper ring 24; The other end of adapter 20 is provided with U type connecting part 27, when adapter 20 combines with axle center 11, the both sides of U type all have screw 272 to establish for interlocking bolt 271 spiral shells, interlocking bolt 271 spiral shells are established pass screw 272, can go deep into the chute 112 of 11 both sides, axle center, adapter 20 is able to and axle center 11 links, supporting of presetting in the adapter 20 end spring 26 then provide when adapter 20 bullets from the axle center 11 strength;

By forming with upper member, then make the bolt part 212 of adapter 20 combine with crank 30 mutual lockings, see through to pass stopper ring 24 simultaneously and break away from balls 22 (please cooperate consult shown in Figure 5), can make the grafting in pedal 10 axle center 11 close 111 when wearing adapter 20, get the ball 22 of in good time jacking sleeve pipe 21 internal diameter edge and reach the effect that stretches through, simultaneously when loosening stopper ring 24, can pass by shoring spring 23, it just can be compressed among the ring pearl groove 111a that is embedded at 11 Plug Divisions 111, axle center that contracts in the ball 22, not only pedal 10 has smooth-going pivot effect, more can realize fast and convenient disassembling function; And when adapter 20 pushed away axle center 11, because connecting part 27 is with moving ring 24 snappings and link adapter 20 and axle center 11, pedal 10 hung down automatically, promptly just like folding function, and makes pedal can not protrude in the bicycle both sides.

In sum, " but collapsible type pedal " of the present utility model, a kind of quick-disassembly structure of being made up of adapter and pedal axle center is provided, after making this adapter be locked in crank, not only can provide pedal fast and convenient assembly and disassembly, to improve packaging efficiency and to tear folding easily open, also can guarantee the smoothness that pedal rotates simultaneously, and make integral body have industrial applicability and cost benefit.

The above is specific embodiment of the utility model and the know-why used, all changes of doing according to conception of the present utility model, the function that it produced. when effect does not exceed specification sheets and graphic contain spiritual yet, all should be in scope of the present utility model.
