Abstract

A pedal comprises a pedal shaft, a pedal bowl, a pedal fastener and a locknut, etc. When processing the pedal shaft, the narrow-bore length of the prior pedal shaft is reduced to 10 mm and the anti-looseness channel of the narrow-bore screw thread part of the prior pedal shaft is cancelled; when processing the pedal fastener, the screw thread arranged on the inner hole of the prior pedal fastener and the concave channel arranged on the outer side face of the prior pedal fastener used to install the pedal fastener are cancelled; a clamp nut is arranged at the outside of the pedal fastener without being provided with a concave channel and arranged on the external side face of an inner hole without screw thread through being inserted into the pedal bowl positioned on the pedal shaft. The utility model has the advantages of flexible use, convenient assembly and maintenance, less breakdown and longer service life of pedal; therefore, the utility model is suitable to be used in various bicycles (boosting bicycles) and tricycles.

Description

A kind of pedal

The utility model relates to a kind of accessory of the vehicle, especially relates to a kind of pedal.

At present, known bicycle (mini-motorcycle), pedal that three-wheel vehicle uses are made up of materials such as pedal axle, cup, steel ball, pedal bumper, anti-slow nut, anti-slow ring washers.The small diameter part that existing pedal axle one end is installed pedal bumper divides processing long, and it is moving to the inboard string in the thin footpath of pedal axle that pedal bumper or steel ball often take place in daily use, makes its pedal rotate dumb after string is moving or does not rotate.Partly be processed with anti-slow ditch at the thin footpath of its pedal axle screw thread, in order to anti-slow ring washer to be installed.Existing pedal bumper is mounted on the pedal spindle of side in the foot-operated bowl, in its pedal bumper, be processed with screw thread on the eye, on foot-operated shelves lateral surface, also be processed with chase, use during in order to the installation pedal bumper, this pedal, at the assembling pedal bumper, inconvenience during the levelling gap, if the pedal bumper wearing and tearing, dismounting is more inconvenient.These bring a lot of troubles and inconvenience for user's daily life work, have increased manufacturing procedure to the producer.

The purpose of this utility model is to overcome the prior art weak point, provides a kind of assembling easy to maintenance, and operational failure is few, uses brisk a kind of easily pedal flexibly.

The purpose of this utility model is achieved in that

The utility model adopts existing bicycle (mini-motorcycle), three-wheel vehicle is employed rides, and when its processing pedal spindle, shortens the thin electrical path length of pedal axle, and making its thin electrical path length is 10mm.Anti-slow ditch on the screw thread of the thin footpath of cancellation pedal axle.When its processing pedal bumper, employed chase when on the screw thread in the cancellation pedal bumper on the eye and this pedal bumper lateral surface pedal bumper being installed.On its pedal axle, do not have the pedal bumper outside that chase is installed on the without screw thread lateral surface on the eye in packing in the cup and load onto clamp nut by sealing in.

Advantage of the present utility model is:

1, a kind of pedal axle of pedal, owing to shorten thin electrical path length, the anti-slow ditch of the thin footpath of cancellation screw thread part prevents that pedal bumper or steel ball are moving to the inboard string of pedal axle, reduces the pedal fault, operating cycles is long, and is flexible.

2, a kind of pedal bumper of pedal, owing to do not process screw thread on the eye in the pedal bumper, installation and processing chase not on the lateral surface is saved manufacturing procedure, prolongs the operating cycles of pedal bumper, uses flexibly, assembles easy to maintenance.

3, a kind of foot-operated purposes is wide, can be used in various bicycles (mini-motorcycle), on the three-wheel vehicle.

Below in conjunction with drawings and Examples the utility model is further specified:

Fig. 1 is a front view of the present utility model

Fig. 2 is a left view of the present utility model

Fig. 3 is among the A-A cutaway view figure of the present utility model, 1, and axis body 1a, pedal axle 1b, pedal bumper 1c, clamp nut

As shown in the figure, the utility model has one to use the pedal axle, cup, the axis body (1) that material such as pedal bumper and clamp nut is formed, axis body (1) adopts the pedal axle (1a) of existing pedal, when its processing pedal axle (1a), shorten the thin electrical path length of pedal axle (1a), making its thin electrical path length is 10mm, the anti-slow ditch of the thin footpath of cancellation pedal axle (1a) screw thread part, to substitute the existing long small diameter part branch of pedal axle, moving to the inboard string of pedal axle (1a) in order to prevent pedal bumper (1b) or steel ball, make axis body (1) use flexibly brisk convenience.Eye is gone up in packing in the cup that pedal axle (1a) seals in does not have the pedal bumper (1b) that chase is installed on the without screw thread lateral surface, because going up the without screw thread lateral surface, pedal bumper (1b) lining eye do not have the installation chase, make pedal bumper (1b) easy for installation, save time, be convenient to assembling and maintenance.Pedal axle (1a) go up by seal in pack in the cup in eye go up the outside of not having the pedal bumper (1b) that chase is installed on the without screw thread lateral surface and load onto clamp nut (1c), to substitute existing anti-slow ring washer, prevent that pedal bumper (1b) from moving to pedal axle (1a) outside string.During use, a kind of pedal can be used on various bicycles (mini-motorcycle), the three-wheel vehicle.

Claims (3)

1, a kind of pedal comprises the axis body of forming with materials such as pedal axle, pedal bumper, cup, clamp nuts (1), it is characterized in that: axis body (1) is not processed anti-slow ditch on the long thin footpath of the 10mm of pedal axle (1a).

2, a kind of pedal according to claim 1 is characterized in that: eye is gone up and is not had the pedal bumper (1b) that chase is installed on the without screw thread lateral surface in sealing on the thin footpath of the anti-slow ditch of the nothing of pedal axle (1a).

3, a kind of pedal according to claim 1 is characterized in that: load onto clamp nut (1c) in the outside that seals in pedal bumper (1b) on the thin footpath of pedal axle (1a).
