Abstract

The utility model relates to a durable manpower vehicle pedal without balls, comprising a pedal axis, a foot rest and a distance sleeve. The utility model is characterized in that one end of the pedal axis is screw threads matched with a crank and one end is a shoulder integrated with the pedal axis; the surface of the axle is provided with a helical oil groove; the foot rest is an overall structure made of rigid plastic, light metal or metal. The utility model has the advantages of simple structure, less parts, no faults and worries of pedal falling, locking, inefficient rotating, etc., convenient maintenance and long service life.

Description

Durable manpower vehicle pedal without balls

The utility model relates to a kind of rickshaw pedal, belongs to the human powered vehicle accessory.

Human powered vehicle pedals such as existing bicycle though the first time spent is flexible, are out of order easily, easily come off as the pedal axle lock nut and to cause whole pedal to break away from the pedal axle, a little axle bowl easily abrasion steel ball enters straight tube and blocks pedal, rotates ineffectively, scarce limit such as does not grow service life.

It is a kind of simple in structure that the purpose of this utility model is to provide, and part is few, and rotate the pedal of flexible long service life.

The utility model is to realize like this, it is made up of pedal axle, spacer and three parts of single-piece stretcher, its main characteristics is on the surface of pedal axle spiral oil groove to be arranged, and there is an axle head shoulder to make the stretcher location, there is being filler port oily on the shoulder to reduce the friction between step tread plate and the pedal axle, though the effect of cliding friction is not as friction of rolling, the rotative speed of pedal is not high, adopts cliding friction not influence the use of pedal.

To be further described by embodiment of the present utility model and accompanying drawing thereof below:

Accompanying drawing 1 is the durable rickshaw pedal structure of no ball figure.

Detailed description of main elements is as follows:

1, crank 2, spacer 3, stretcher 4, pedal axle 5, oil groove 6, filler port 7, axle head shoulder.

Referring to Fig. 1, pedal axle (4), the screw thread that one end has and crank (1) cooperates, one end is the shoulder (7) as a whole with the pedal axle, and the shoulder appearance makes 6 sides' profile, so that with spanner the pedal axle is tightened on the crank, spiral oil groove (5) is arranged on the surface of pedal axle, filler port (6) is arranged on shoulder, and filler port has spring and steel ball sealing, in order to avoid dust enters.Step tread plate 3, as a whole, there is an axis hole that cooperates with the pedal axle at the center, and hollow ring-type can be made to reduce weight in the axis hole both sides, and shape can be made different shapes such as rectangle, garden arc.Its material can be that rigid plastic or light metal or metal are made.Spacer (2) is contained between crank (1) and the stretcher, and purpose is to reduce friction, and during installation, earlier stretcher is installed on the pedal axle, refills spacer, is screwed in the screw of crank 1 to get final product.

In sum, the utility model has the following advantages:

1, simple in structure, part is few, only have 3 parts;

Although 2 is to adopt 3 sliding friction structures, rotates flexibly, does not affect use;

3, easy to maintenance, long service life;

4, do not have distortion, the stuck rotation of ball is ineffective, the pedal worry that fault takes place such as come off.

Claims

1, the durable rickshaw pedal of a kind of no ball, comprise pedal axle, stretcher, spacer, it is characterized in that pedal axle (4) is that an end is the screw thread that cooperates with crank (1), one end is the shoulder (7) in aggregates with the pedal axle, helical oil groove (5) is arranged on the surface of axle, stretcher (3) is the whole stretcher that there is the axis hole that cooperates with pedal axle (4) at a center, between stretcher (3) and crank (1) spacer (2) is arranged.

2, rickshaw pedal according to claim 1 is characterized in that pedal pillow block shoulder (7) is a hexagon, on filler port is arranged.

3, rickshaw pedal according to claim 1 is characterized in that stretcher made by duroplasts or light metal or metal.
