Abstract

The utility model relates to a bicycle pedal, comprising a shaft, a shaft sleeve and a pedal. The shaft sleeve and the pedal are fabricated to integration and are matched and tightly locked with the shaft, the pedal is caused to be flexibly rotate around the shaft, and the pedal can not carry out the axial displacement; the defects of the existing pedal is overcome; the defects comprise that the quantity of components are large, the looseness and the falling apart are easily generated, and the maintenance is inconvenient; besides, the service life is short. The utility model is suitable for various bicycles, tricycles and other vehicles which need the similar pedal.

Description

Bicycle pedal

The utility model belongs to bicycle pedal.

At present, China's bicycle pedal all is to adopt a plurality of parts (about more than 20) to assemble, under external force, very easily produce loosening and distortion between the part, be contained in the axle and the ball of axle sleeve connection place also very easily because of the distortion landing of axle and axle sleeve, cause stretcher to rotate malfunctioning even fall apart, and a certain damage parts of stretcher repair also inconvenience, the a large amount of optical axises that caused town and country to be found everywhere are worked as the bicycle of pedal, and the traffic accident that causes thus is also of common occurrence.

In order to overcome above-mentioned defective or deficiency, the purpose of this utility model is to provide the whole self-propelled car stretcher that a kind of component part is few, simple in structure, rotate flexibly, do not fall apart, do not have distortion.

Technical solution of the present utility model is: a kind of bicycle pedal, comprise axle, axle sleeve and pedal, its special character is that an end of axle has the screw thread that matches with bicycle turning screw, cooperate with axle sleeve at the axle journal place, the axle sleeve level is rotated flexibly around axle journal, pedal and axle sleeve are unified into an integral body, and the other end of axle is by pad, back-up ring or other tightly encloses part and pedal joins together.

The utility model has the advantages that, the few globality of number of packages is strong in addition, can not produce the phenomenon that the pedal part is loosening and fall apart, saved raw MAT'L to mould for steel, and low price, simplified manufacture craft, repair and replacement are convenient, be applicable to all kinds of bicycles, three-wheel vehicle and the place of useful similar existing stretcher.

Fig. 1 is the utility model integral structure figure.

Fig. 2 is the utility model integral structure left view.

Fig. 3 is along Figure 1A-A line cutaway view.

Below in conjunction with accompanying drawing the utility model most preferred embodiment is further described: use metallic material, the axle sleeve (2) of the most handy " iron one carbon " powder metallurgy material is injection-moulded in together with pedal (3), the outside face of axle sleeve is processed with rough decorative pattern, binding force with increase and pedal, the pedal plastics, preferably adopt rigid polyvinyl chloride to make, two foot-operated outside faces at pedal have concavo-convex netted or other decorative pattern, both sides also have the anti-skidding chimb (7) of edge perpendicular to the axis direction of axle on this surface, and lightening hole and loss of weight groove are arranged on the pedal.Axle (1) passes in the middle of the axle sleeve, and the side by an end step surface withstands pedal makes axle journal (4) cooperate with axle sleeve, locks with pad (5) and back-up ring (6) and pedal at the other end of axle, or fixes with other fastener.At this moment pedal can only can not produce around flexible rotation of axle and move axially.Then the thread end of the axle that cooperates with bicycle turning screw is screwed into the bicycle turning, bicycle pedal just can use for normal.In order to reduce the friction of axle journal and axle sleeve, also can locate to add the moderate lubrication agent in the intermediate gaps (8) that axle cooperates with axle sleeve.

Claims

1, a kind of bicycle pedal, comprise axle (1), axle sleeve (2), a pedal (3), it is characterized in that axle (1) that an end has the screw thread that matches with bicycle turning screw axle journal (4) locate with can around rotate flexibly and and the axle sleeve (2) that becomes one of pedal (3) cooperate, spool the other end join together by fastener and pedal.

2, bicycle pedal according to claim 1 is characterized in that axle sleeve (2) has the raised and concave figures outside face that increases with the pedal binding force.

3, bicycle pedal according to claim 1 and 2 is characterized in that axle sleeve (2) is with " iron one carbon " powder metallurgy material.

4, bicycle pedal according to claim 1 is characterized in that having lightening hole, the pedal of groove (3) outside face has ridge design, has on the both sides of pedal two foot-operated outside faces along the anti-skidding chimb (7) perpendicular to the axis direction of axle.

5,, it is characterized in that pedal (3) is a rigid polyvinyl chloride integral molded plastic spare according to claim 1 or 4 described bicycle pedals.
