CN2289747Y - Abrasion-resistant roller frame for pedal of bicycle and tricycle - Google Patents

Abstract

The utility model relates to a wear resistant roller frame for pedals of bicycles and tricycles, which belongs to the field of fittings of bicycles and tricycles. The utility model is a ring made of wear resistant plastics and provided with braking clamped claws on the excircle cambered surface, and the ring has a certain wall thickness. When the utility model is used to match with a pedal frame provided with braking clamped grooves, the braking clamped claws of the wear resistant roller frame are embedded into the braking clamped grooves arranged on both ends of a center hole of the pedal frame so as to cause the wear resistant roller frame and the pedal frame to form into integration which can not rotate correspondingly, and then an axis fender is forced to rotate only contact with the convex circle cambered surface of one end surface of the wear resistant roller frame, and thereby, steel bowls and steel balls are replaced and the service life of pedals is prolonged. The utility model has the advantages of simple structure, flexible rotation, convenient assembly and disassembly and convenient maintenance.

Description

A kind of bicycle, three-wheel vehicle pedal are with the wear-resisting frame that rolls

The utility model is that application number is 97213959.1, and name is called dividing an application of " a kind of bicycle, three-wheel vehicle pedal and wear-resisting frame, connecting plate steel bowl and the pedal framework of rolling thereof ".

The utility model belongs to bicycle, three-wheel vehicle accessory field, and particularly a kind of bicycle, three-wheel vehicle pedal are with the wear-resisting frame that rolls.

In recent years, popular bicycle, three-wheel vehicle pedal on the market, its pedal framework is to use plastic injection-moulded all-in-one-piece, and is in light weight because of having, the exterior design favor that day by day is subjected to people attractive in appearance.But owing to the reason in the design, existing plastics pedal framework, at the medium pore both ends steel bowl and steel ball are installed, steel bowl and plastic frame are the flush fit assembling, do not design brake equipment, after using a period of time, steel ball increases because of the oil starvation resistance, and plastic frame wears out because of period of service is long, makes the matching loose of steel bowl and plastic frame, both relatively rotate easily, and it is mashed the plastic frame mill steel bowl, steel ball usually to occur.

The purpose of this utility model is, provides a kind of braking claw that has also can be used with plastics pedal framework or connecting plate steel bowl, and the wear-resisting frame that rolls of energy instead of steel bowl and steel ball.

For achieving the above object, the utility model adopts following technical scheme:

A kind of bicycle, three-wheel vehicle pedal are with the wear-resisting frame that rolls, and it is make and the annulus that certain wall thickness is arranged of a usefulness wear-resistant plastic, and its cylindrical cambered surface is provided with at least two braking claws.

This wear-resisting braking claw that rolls frame has two, and it is shaped as rectangular bar shaped.

These wear-resisting two end faces that roll frame can be plane or convex arc surface with the position that the axle shelves contact.

With the pedal framework that the utility model is used, it is with having the pedal framework of braking draw-in groove on plastic injection-moulded all-in-one-piece, interior round youngster's perisporium of aperture, medium pore two ends greater than median pore radius and increase position, aperture, two ends.

With the connecting plate steel bowl that the utility model is used, it is having the connecting plate steel bowl that the steel bowl of brake draw-in groove and plate are made one, justifies braking draw-in groove on youngster's perisporium and quantity corresponding with wear-resisting position of rolling the retaining pawl card on the frame in the steel bowl and equates.

The utility model adopts the technical scheme that is used with pedal framework or connecting plate steel bowl, the aperture, medium pore two ends of the pedal framework that the wear-resisting braking claw that rolls frame is embedded plastics pedal framework or is made up of parts such as connecting plate steel bowls increases in the braking draw-in groove of justifying in the position on youngster's perisporium, make it can not be in relative rotation whole with its formation, force axle shelves can only with wear-resisting roll frame wherein the convex arc surface of an end face contact rotation, contact effective, coefficient of friction is little, thereby instead of steel bowl and steel ball, pedal is prolonged service life, avoided the steel bowl, steel ball is because of the damageable shortcoming of oil starvation, it is simple in structure, rotate flexibly, not fragile, dismounting is easy to maintenance.

The utility model is described in further detail by embodiment below in conjunction with accompanying drawing:

Embodiment 1, see Fig. 1,2,3,4,5,6, a kind of bicycle, three-wheel vehicle pedal are with the wear-resisting frame that rolls, it comprises the annulus of being made by wear-resistant plastic that certain wall thickness is arranged 1, its exterior arc surface is provided with two and the corresponding braking claw 2 in braking draw-in groove position, and two end face is a convex arc surface 3 with the position that the axle shelves contact.

When the utility model and pedal framework are used, see Fig. 7,8, the wear-resisting braking claw 2 that rolls frame 19 is embedded in the frame medium pore 12 two ends braking draw-in groove 7 of pedal frame 14, make it can not be in relative rotation whole with its formation, force axle shelves 16,20 can only with wear-resisting roll frame 19 wherein the convex arc surface 3 of an end face contact rotation, thereby instead of steel bowl and steel ball reach not fragile, prolong the pedal purpose in service life.

When the utility model and connecting plate steel bowl 26,27 are used, see Fig. 9,10,11,12, the wear-resisting braking claw 2 that rolls frame 19 is embedded in the braking draw-in groove 7 of connecting plate steel bowl 26,27, make it can not be in relative rotation whole with its formation, force axle shelves 16,20 can only with wear-resisting roll frame 19 wherein the convex arc surface 3 of an end face contact rotation, thereby instead of steel bowl and steel ball reach not fragile, prolong the pedal purpose in service life.
