Abstract

The utility model provides a combination-type folding pedal of a bicycle, which comprises a right pedal and a left pedal which are connected with both ends of the bottom bracket of the bicycle, one pedal is a turnover-type folding pedal, and the other pedal is a crank rotating type folding pedal; the two pedals are positioned at the same end of the bicycle after respectively folded; the two pedals are overlapped from inside to outside, and the pedal board of the turnover-type pedal is positioned at the outside layer. The combination-type folding pedal of a bicycle has simple structure and convenient folding; and the two pedals are positioned at the same end of the bicycle after respectively folded, so the transverse space as well as the length space is saved, and the folding pedals are very practical for a folding bicycle.

Description

Combined type folding pedals of bicycle

Technical field

The utility model relates to bicycle, particularly a kind of combined type folding pedals of bicycle.

Background technology

In various folding bicycles, with bicycle pedal also fold up few.And bicycle pedal part if do not folded, then influences the folding effect of bicycle because its horizontal space that takies when stretching is bigger greatly.The report that has pair bicycle pedal to fold in the prior art is directly made crank 180 degree upsets but mostly be, so that pedal turns to the inboard by the outside.Because two pedals of bicycle are oppositely to be provided with, if two pedals are all done 180 degree upsets and are folded, then the result still becomes 180 degree reverse geometries, though laterally saving the space, but a bit do not save at length direction, this structure influence the folding effect of bicycle, especially if bicycle folding is become box-type bike, this structure is unworkable.

The utility model content

The purpose of this utility model in order to solve the problems referred to above that prior art exists, provides a kind of combined type folding pedals of bicycle with new structure exactly.

The technical solution of the utility model is: a kind of combined type folding pedals of bicycle, comprise be connected the bicycle middle shaft both sides about two pedals, be characterized in, about described in two pedals, one is convertible folding pedals, and another is a crank rotary type folding pedals, all is positioned at the same end of bicycle after two pedals are folding respectively, and two step tread plates are inside and outside superimposed, and wherein the step tread plate of convertible folding pedals is positioned at skin.

Described crank rotary type folding pedals comprises crank and one group of the locking and unlocking mechanism, crank is connected and composed with coaxial rotation mode by crank body and crank head two parts, and the locking and unlocking mechanism is installed in the crank body locking to be stoped its rotation or unlock on the crank head and allows its rotation.

Described crank body is provided with an axial deep hole at itself and crank head bonded assembly one end, described crank head is provided with and the adaptive joint pin of above-mentioned axial deep hole, on this joint pin, be provided with a ring annular groove, two tommys pass crank body and insert and crank body is linked to each other with the crank head in this circular groove, two tommys can slide along circular groove, and the realization crank body is done coaxial rotation around the joint pin of crank head.

Described the locking and unlocking mechanism comprises lock pin, retracing spring, release push button and tie bolt, described crank head is provided with the slotted hole that is used for ccontaining lock pin and retracing spring, described crank body is provided with the lockhole that is used to allow lock pin insert, lock pin be arranged on above-mentioned slotted hole or and lockhole in, the inner that retracing spring is arranged on slotted hole provides reseting elasticity for lock pin; The release push button is arranged on the outside of crank head and is fixedly linked by tie bolt and lock pin, is provided with the long slot bore of allowing that the tie bolt work axially moves back and forth in the relevant position of crank head.

The utility model combined type folding pedals of bicycle is simple in structure, folding convenient; All be positioned at the same end of bicycle after two pedals are folding respectively, both saved horizontal space, saved the length space again, be highly advantageous to and make box-type folding bicycle.

The specific embodiment

The utility model is described in further detail below in conjunction with specific embodiment.

Referring to Fig. 1, cooperation is referring to Fig. 3, combined type folding pedals of bicycle of the present utility model, comprise be connected bicycle middle shaft 1 both sides about two pedals 2 and 3, about in two pedals 2 and 3,2 is convertible folding pedals (for prior art), 3 is crank rotary type folding pedals, all be positioned at the same end of bicycle after two pedals are folding respectively, and two

step tread plates

21,31 are inside and outside superimposed, wherein the step tread plate 21 of convertible folding pedals is positioned at skin.

Referring to Fig. 2, crank rotary type folding pedals 3 in the utility model comprises crank 32, step tread plate 31 and one group of the locking and unlocking mechanism 33, crank 32 is connected and composed with coaxial rotation mode by crank body 321 and crank head 322 two parts, and the locking and unlocking mechanism 33 is installed in crank body 321 lockings to be stoped its rotation or unlock on the crank head 322 and allows its rotation.

Continuation is referring to Fig. 2, crank body 321 in the utility model is provided with an axial deep hole 3211 at itself and crank head 322 bonded assemblys one end, the crank head is provided with the joint pin 3221 adaptive with above-mentioned axial deep hole, on this joint pin, be provided with a ring annular groove, two tommys 4 pass crank body respectively and insert in this circular groove crank body 321 is linked to each other with crank head 322 from the both sides of crank body, two tommys 4 can slide along circular groove, and the realization crank body is done coaxial rotation around the joint pin 3221 of crank head.

Continuation is referring to Fig. 2, the locking and unlocking mechanism 33 in the utility model comprises lock pin 331, retracing spring 332, release push button 333 and tie bolt 334, on crank head 322, be provided with the slotted hole that is used for ccontaining lock pin and retracing spring, on crank body 321, be provided with the lockhole 3212 that is used to allow lock pin insert, lock pin 331 be arranged on above-mentioned slotted hole or and lockhole in, the inner that retracing spring 332 is arranged on slotted hole provides reseting elasticity for lock pin; Release push button 333 is arranged on the outside of crank head 322 and is fixedly linked by tie bolt 334 and lock pin 331, is provided with the long slot bore of allowing tie bolt and doing axially to move back and forth (not shown come out) in the relevant position of crank head 322.
