Abstract
The utility model provides a crank rotating type folding pedal of a bicycle, which comprises a crank and a pedal. The crank is formed by the connection of a crank body and a crank head in a coaxial rotation mode; the folding pedal further comprises a set of locking and unlocking mechanism which is mounted on the crank head to lock the crank body for preventing the crank body from rotation or unlock the crank body for allowing the crank body rotating. The crank rotating type folding pedal of a bicycle has simple structure and convenient folding; and the joint between the crank body and the crank head is firm because of the arrangement of the locking and the unlocking mechanism, so the use is safe and reliable.
Description
Technical field
The utility model relates to bicycle, particularly a kind of crank rotary 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 crank rotary type folding pedals of bicycle with new structure exactly.
The technical solution of the utility model is: a kind of crank rotary type folding pedals of bicycle, be connected on the axis of bicycle, comprise crank and pedal, be characterized in, described crank is connected and composed with coaxial rotation mode by crank body and crank head two parts, also comprise one group of the locking and unlocking mechanism, this 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 crank rotary type folding pedals of bicycle is simple in structure, folding convenient; Owing to be provided with the locking and unlocking mechanism, the combination between crank body and the crank head is firm, safe and reliable.

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 all the other each figure, crank rotary type folding pedals of bicycle of the present utility model, be connected on the axis 1 of bicycle, comprise crank 2, pedal 3 and one group of the locking and unlocking mechanism 4, crank 2 is connected and composed with coaxial rotation mode by crank body 21 and crank head 22 two parts, and the locking and unlocking mechanism 4 is installed in crank body 21 lockings to be stoped its rotation or unlock on the crank head 22 and allows its rotation.
Referring to Fig. 3, cooperation is referring to all the other each figure, crank body 21 in the utility model is provided with an axial deep hole 211 at itself and crank head 22 bonded assemblys one end, the crank head is provided with the joint pin 221 adaptive with above-mentioned axial deep hole, on this joint pin, be provided with a ring annular groove, two tommys 5 pass crank body respectively and insert in this circular groove crank body 21 is linked to each other with crank head 22 from the both sides of crank body, two tommys 5 can slide along circular groove, and the realization crank body is done coaxial rotation around the joint pin 221 of crank head.
Referring to Fig. 3, cooperation is referring to all the other each figure, the locking and unlocking mechanism 4 in the utility model comprises lock pin 41, retracing spring 42, release push button 43 and tie bolt 44, on crank head 22, be provided with the slotted hole that is used for ccontaining lock pin and retracing spring, on crank body 21, be provided with the lockhole 212 that is used to allow lock pin insert, lock pin 41 be arranged on above-mentioned slotted hole or and lockhole in, the inner that retracing spring 42 is arranged on slotted hole provides reseting elasticity for lock pin; Release push button 43 is arranged on the outside of crank head 22 and is fixedly linked by tie bolt 44 and lock pin 41, 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 22.
The normal operating condition of crank rotary type folding pedals of bicycle of the present utility model as shown in Figure 1, at this moment pedal is positioned at the outside of crank, lockhole 212 interior realizations that lock pin 41 in the locking and unlocking mechanism 4 inserts crank body 21 lock, and coaxial rotation can not take place between crank body 21 and the crank head 22.When the needs rotary folding, release push button 43 is inwardly promoted, lock pin 41 is withdrawed from the lockhole 212 of crank body 21, at this moment, the locking of crank body 21 is disengaged, and with its Rotate 180 degree, pedal 3 has been realized folding as Fig. 2, the inboard that forwards crank to shown in Figure 4.
