Description

The pedal device for quickly disassembling

Technical field

The utility model relates to a kind of pedal, and a kind of pedal device for quickly disassembling that provides rapid, for convenience detach replacement pedal to use is provided.

Background technology

The modern not only is light comfortable for the requirement of bicycle, also quite pay attention to for the sturdy and durable of configuration aspects, do not losing under the firm situation of attractive in appearance and structure, the framework of bicycle body's each several part changes with replaceable design and becomes trend trend already.

See also TaiWan, China patent application case number No. 90220059 " bicycle pedal crank device for quickly disassembling " patent, comprising: stretcher, an end of stretcher has protruded out a rotating shaft, then forms the externally threaded screw part of a tool on the free end of this rotating shaft; Fixedly swivel nut is the sleeve body of a central tool functional hole, make this fixedly the functional hole of swivel nut be screwed together on the screw part of stretcher, fixedly swivel nut then is convexly equipped with out the blocking flange of five equilibrium at least by the fixing outer rim of swivel nut away from the in addition end of stretcher again; Pedal crank, on its free end, wear a trepanning of setting for fixing swivel nut, this trepanning inside is with respect to the fixing blocking lugs position of swivel nut, respectively be concaved with the caulking groove of leading for the embedding of blocking flange, then be arranged with a degree of depth and be slightly larger than the blocking thickness of flange with respect to a side of leading caulking groove in the side end face in addition of this pedal crank again by this end face away from fixing swivel nut, and distribute along the circle footpath of trepanning and with lead caulking groove and form the clamping slot that communicates.

Yet, though this kind bicycle pedal device for quickly disassembling can provide dismounting to replace the effectiveness of pedal, but its manner of execution is to utilize the rotating shaft of pedal one end to combine with sleeve body, again the blocking flange of sleeve body one end external diameter and the caulking groove card of leading of crank trepanning are set the position, when desire is dismantled, need utilize instrument with pedal together with the relative trepanning turn of sleeve body to certain degree, make the blocking flange and lead caulking groove and break away from, just can make this moment pedal and crank break away from, its operating mode is quite loaded down with trivial details and convenient inadequately; Or have the dealer to design the chimeric so that design that quick detach uses of pedal and crank elasticity, but it still need utilize instrument and device for quickly disassembling effect could make pedal and crank disengaging, and none is available for users to the design that quick manual is operated, so poor practicability.

The utility model content

Technical problem underlying to be solved in the utility model is, overcomes the above-mentioned defective that prior art exists, and a kind of pedal device for quickly disassembling is provided, and it can provide the effect of rapid, for convenience detach replacement pedal.

For reaching aforesaid creation purpose, the utility model comprises that one can be for connecting element, a conjunction, a control unit and the pulling block established with the pedal group, wherein:

This connecting element one end is for establishing with the pedal group, and the other end is provided with an edge clipping, this edge clipping both sides external diameter is to be to scabble shape, this edge clipping is to supply connecting element and conjunction to fasten group to establish, and generation prevents the effect that conjunction relative fixed part rotates, and be to offer an embedded hole on this connecting element, this embedded hole is to be used in the conjunction and the control unit effect, can be rapid for the user to provide, the effect of pedal for convenience detach;

This conjunction is to offer a combined hole and a functional hole, this functional hole is to be the vertical kenel that communicates with combined hole, wherein this combined hole proximity junction component edge is both sides to scabble shape, and be to be provided with a spacing edge in the combined hole, thereby when connecting element and conjunction group are established, the edge clipping of connecting element is to replace the location with this spacing edge, makes conjunction just make embedded hole and functional hole be relative kenel with the bonding state of connecting element;

This control unit comprises that a control stalk, is to being subjected to part, an elastic component, a steady ring and a pulling block, wherein should support and be subjected to part is to establish fixing with the functional hole spiral shell, and should support is subjected to part central authorities to offer a perforation, this perforation is to hold control stalk to enter, and it is corresponding chimeric with the embedded hole of connecting element that control stalk is extended to by the functional hole place; This steady ring is to bind perforation place that is mounted in being subjected to part, it is to wear usefulness for control stalk, and this steady ring is to make with soft materials, and aperture surface is furnished with lubricated thing, during with the relative perforating movable of convenient control stalk, this steady ring provides the positioning control bar and makes the effectiveness that it can smooth and easy slip; This control stalk comprises that one drives section and one chimeric section, this diameter of chimeric section drives Duan Weichang, and the aperture of this chimeric section diameter and embedded hole is suitable, and this elastic component is arranged on the drive section external diameter of control stalk, and the elastic component two ends are be subjected to the part bottom and drive section to replace with chimeric section intersection with supporting respectively, thereby this control piece can be subjected to the pushing and pressing of elastic component and make chimeric section to combine inlay card with embedded hole, this moment, this connecting element was that restriction and the conjunction of controlled bar fixed, thereby pedal and conjunction was fix the state that can't dismantle; In addition, this pulling block is to wear to combine with a part to fix outside conjunction and with control stalk drive Duan Yiduan, and make pulling block become a continuous action relation with control stalk, thereby when the pulling pulling block, this control stalk is moved outward by the drive of pulling block, this moment, chimeric section i.e. disengaging of control piece established state with the card of embedded hole, and pedal can be detached together with the relative in the lump conjunction of connecting element, and behind the relieving pulling block, control stalk is promoted toward the combined hole direction by the pushing and pressing of elastic component then, thereby user's desire is when replacing pedal, can spur pulling block chimeric section of control stalk broken away from embedded hole, and pedal can be extracted out smoothly outward, and desire is when establishing pedal and conjunction group fixedly, only need pedal is inserted in combined hole together with connecting element, fall into the embedded hole internal fixation, promptly finish the action of fixed pedestal and conjunction until chimeric section of control stalk.

The beneficial effects of the utility model are that it can provide the effect of rapid, for convenience detach replacement pedal.
