Abstract

The utility model relates to a bicycle pedal. The inner end of a pedal shaft is provided with a fender shoulder, and the tail end is provided with an annular groove. The inner ring of the outer end of a pedal shell is provided with an elastic collar provided with a plurality of slots along the radial direction; the inner diameter of the elastic collar is smaller than the outer diameter of the shaft end and larger than the diameter of the annular groove. Under the exogenic action, the elastic collar can have a certain axial deformation. After the shell is inserted from the shaft end, the elastic collar is embedded in the groove of the pedal shaft. The utility model only provided with the pedal shaft and the pedal shell has the characteristics of low cost, convenient installation and maintenance, etc.

Description

Bicycle pedal

The utility model relates to a kind of bicycle pedal.

Existing bicycle pedal is divided into two kinds on antifriction-bearing box and plain bearing.The latter has obtained application more and more widely on ordinary bicycle, but the fixing opening circlip of generally using of its pedal shell and pedal axle, this pedal assembling inconvenience, and the enclosing cover of back-up ring and pedal outer casing end easily comes off.

The purpose of this utility model is the deficiency that overcomes existing pedal, and a kind of simple in structure, cost is low, assembling is easy to maintenance bicycle pedal is provided.

There is shoulder block pedal axle of the present utility model the inner, and end has a cannelure; The inner ring of pedal shell outer end has the circlip that radially has some slits, its internal diameter less than the external diameter of shaft end greater than the external diameter of cannelure.This circlip can have certain flexible deformation under external force within the specific limits vertically.After the pedal shell inserted from the tip of the axis, this circlip embedded in the groove of pedal axle.This circlip can be made with shell is whole, also can embed with axle sleeve or the whole back of making of enclosing cover, and the sliding position of pedal shell and pedal axle can embed axle sleeve.

During assembling, only need firmly insert shell from the tip of the axis and get final product.Simultaneously, because need not open the enclosing cover of pedal outer casing end, enclosing cover can be captiveed joint with shell or whole the manufacturing during assembling.When shell damages, a new shell can be inserted again.

Be expendable weight, the pedal axle can be made into hollow tubular, and the end that itself and crank connect can be made into interior hexagonal hole, so that use the hex drive tool Assembly ﹠Disassembly.

Be simplified structure, the pedal axle can be fixedly connected with crank, thereby saves the spiral marking connection between the two, and the two can take hollow tubular structures simultaneously.

For ease of dismounting with adjust, with the right crank of sprocket wheel, the connection between itself and sprocket wheel, available spiral marking connection.

Below in conjunction with embodiment it is described further

See Fig. 1 Fig. 2 and Fig. 3, bicycle pedal is made up of pedal axle 1 and pedal shell 2, at the pedal shaft end one cannelure 3 is arranged, the flexible back-up ring 5 of the inner ring of pedal shell 2 outer ends, greater than the external diameter of cannelure 3, its thickness is less than the width of cannelure 3 less than the external diameter of shaft end for its internal diameter.

See Fig. 4, have some slits 6 on the circlip 5, thereby make circlip 5 that certain axial deformation can be arranged.When from pedal the tip of the axis insertion pedal shell, because the obstruction of pedal axle outer face 4, when continuing to insert, make circlip 5 begin that certain axial deformation is arranged, when being deformed to a certain degree, the inner ring of circlip 5 slips over the pedal the tip of the axis and snaps in the cannelure 3, thereby finishes the assembling of the two.

See Fig. 3, in embodiment of the utility model, circlip 5, enclosing cover 9 is an integral structure with shell.

See Fig. 5, Fig. 8 and Fig. 9, in other embodiment of the present utility model, be inlaid with axle sleeve 8, circlip 5 and enclosing cover 9 in the pedal shell individually or simultaneously, these inserts can and shell between gluing or interference fit, perhaps in the shell manufacturing process, embed.Circlip 5 is an integral body with enclosing cover 9 among Fig. 5, and Fig. 8 bottom bracket axle 8 and circlip 5 are an integral body, only embed axle sleeve 8 among Fig. 9.

See Fig. 2 and Fig. 6, be expendable weight, the pedal axle can be hollow tubulose, and the end that itself and crank connect is provided with interior hexagonal hole, inserts for corresponding hexagonal key wrench.

See Fig. 7 and Figure 10, in another embodiment of the present utility model, be expendable weight, simplified structure, pedal axle 1 can be fixedly connected with crank 10, and the two can take hollow tubular structures simultaneously; With the right crank of sprocket wheel, they can be with the negative thread 13 formation spiral marking connections on outside thread 12 and the sprocket wheel 11 with the connection position of sprocket wheel 11.

The utility model only has crank shaft and two parts of pedal shell, have cost low, simple in structure, The characteristics such as installation and maintenance are convenient have broad application prospects when producing in enormous quantities.
