Abstract
A structure for combining a pedal and a crank of a bicycle comprises a pedal mandrel which is combined on a pedal, and is provided with a first threaded shaft on the end which is extended out from the pedal, and a pivoting screw cap whose one end is provided with a threaded shaft which is combined in a threaded hole of a crank, wherein the pivoting screw cap is provided with a threaded hole which is through the front end and the back end thereof, the first threaded shaft of the pedal mandrel is combined in the threaded hole of the pivoting screw cap. The structure is extremely simple, is provided with the functions of assembly and detachment, can reduce the time for assembling the pedal on the crank in the bicycle product line, and be used by users to replace the pedal individually.
Description
Technical field
The utility model relates to the structure with bicycle pedal and crank combination, this structure is simplified very much, have and be convenient to the function assembling and dismantle, can reduce the man-hour that is assembled in crank in the bicycle manufacturing line about stretcher, and can change stretcher voluntarily for the user of a bicycle.
Background technology
A kind of pedal of bicycle and known techniques of crank combination of making as shown in Figure 1, comprises the drive-connecting shaft 21 that a pedal spindle 11, that combines with stretcher 10 combines with crank 20.This stretcher 10 can rotate freely around this pedal spindle 11, and an end of this drive-connecting shaft 21 has threaded shaft 22, combines with the tapped bore 23 of this crank 20.The other end of this drive-connecting shaft 21 has the hole 24 of this pedal spindle 11 of reception, the structural walls that constitutes this hole 24 has the ball 25 of several annular arrangements, this ball 25 is combined in these drive-connecting shaft 21 exterior control loops 26 by one and controls, and can be synchronous do to the axis direction of this drive-connecting shaft 21 or moving back and forth in its position in contrast to axis direction.The mobile some of this ball 25 that makes to axis direction is protruding in this hole 24, with the ball grooves 12 that further is fastened on this pedal spindle 11, pedal spindle 11 is connected in this drive-connecting shaft 21.Move to the reversing sense in axle center and to make this ball 25 not protrude from this hole 24, and remove snap-fit relationship with this ball grooves 12,11 of this pedal spindle can debouch in this drive-connecting shaft 21.
The structure of above-mentioned drive-connecting shaft 21 has related to small spring, groove, clasp, setting element etc., and this makes the complex structureization of this drive-connecting shaft 21, and because each element is small, assembling and location be difficulty more.Yet, a drive-connecting shaft 21 with structure flaw, will make in the bicycle manufacturing line increases about man-hour and the defect rate that stretcher is combined in crank.
Summary of the invention
Main purpose of the present utility model is, a kind of pedal of bicycle and structure of crank combination of making is provided, this structure is simplified, have and be convenient to the function assembling and dismantle, but be combined in the flow process of crank in the reduced proper motion car manufacturing line about stretcher, and can change stretcher voluntarily for the user of a bicycle.
The utility model is reached the major technique of above-mentioned purpose, and a kind of stretcher of bicycle and structure of crank combination of making is characterized in that this structure comprises:
One is incorporated into the pedal spindle of a stretcher, and the end that this pedal spindle is extended this stretcher has one first threaded shaft;
One articulates nut, and the one end has a threaded shaft, and this threaded shaft is incorporated in the tapped bore of a crank; This pivot joint nut has a tapped bore that runs through its front and back end, and first threaded shaft of above-mentioned pedal spindle is incorporated into the tapped bore of this pivot joint nut.
The utility model beneficial effect: the utility model based on thread structure in conjunction with articulating nut and this pedal spindle, simplifying of connection structure with crank and stretcher, and simplified the flow process that stretcher is combined in crank, make that the assembling flow path about stretcher and crank is simplified in the bicycle manufacturing line, and because stretcher is assembled in the method for crank is simple, so can allow the general user of bicycle change stretcher voluntarily.
Description of drawings
Fig. 1 is the prior art that is assembled in crank about stretcher.
Fig. 2 is about stretcher and pedal spindle thereof and crank and articulate the three-dimensional exploded view of nut in the utility model package assembly.
Fig. 3 is about the three-dimensional exploded view of stretcher and pedal spindle in the utility model package assembly.
Fig. 4 utilizes the utility model structure to make stretcher be assembled in the stereo appearance figure of crank.
Fig. 5 utilizes wooden case structure to make stretcher be assembled in the combination section of crank.
The specific embodiment
Fig. 2, Fig. 4 and Fig. 5 disclose the structure that bicycle pedal 30 is combined in crank 50, comprise the pivot joint nut 60 that a pedal spindle 40, that combines with stretcher 30 combines with crank 50.One end of this pivot joint nut 60 has a threaded shaft 61, combines with the tapped bore 51 of this crank 50.This pivot joint nut 60 has a tapped bore 62 that axially runs through its front and back end.The part that this pedal spindle 40 is extended beyond this stretcher 30 is one first threaded shaft 41, and this first threaded shaft 41 combines with the tapped bore 62 of this pivot joint nut 60, can make stretcher 30 be assembled in crank 50.
Fig. 3, Fig. 5 disclose the connection structure of pedal spindle 40 and stretcher 30.This pedal spindle 40 is extended through in the arbor hole 31 of this stretcher 30, two groups of rolling assemblies 70 wear the outer wall due to this pedal spindle 40, and the sidewall that constitutes this arbor hole 31 is preset with two rolling assembly location divisions 32, and these two groups of rolling assemblies 70 further are positioned in this two rolling assemblies location division 32.The end that this pedal spindle 40 penetrates this arbor hole 31 wears connection one barrier module 71 with second threaded shaft 42, and this barrier module 71 has comprised two block nuts 72,73 and an intervenient packing ring 74 in legend.The open end of the arbor hole 31 of this stretcher 30 is fixed a closure elements 75.Based on above structure, this stretcher 30 combines with this pedal spindle 40, and can freely rotate around this pedal spindle 40.
Based on thread structure in conjunction with above-mentioned pivot joint nut 60 and this pedal spindle 40, with connection structure simplify of crank 50 with stretcher 30, and simplified the flow process that stretcher 30 is combined in crank 50, make that the assembling flow path about stretcher and crank is simplified in the bicycle manufacturing line, and because stretcher 30 is assembled in the method for crank 50 is simple, so can allow the general user of bicycle change stretcher voluntarily.
In addition, the threaded shaft 61 of above-mentioned pivot joint nut 60 combines with the tapped bore 51 of crank 50, first threaded shaft 41 of above-mentioned pedal spindle 40 combines with the tapped bore 62 that articulates nut 60, all can utilize known dextrorotation or left-handed hand of spiral to guarantee that this pedal 30 is trampled by the user and when driving bicycle and moving ahead, this pedal spindle 40 can not break away from this pivot joint nut 60, and this pivot joint nut 60 can not break away from this crank 50.
