Abstract

The utility model belongs to a bicycle pedal, particularly a bicycle pedal whose shaft tube and shaft are assembled into a whole. The utility model is suitable for various bicycles. The shaft tube made of non-metallic materials is sheathed with and is in sliding fit with a pedal shaft made of steel. Besides, one end of the pedal shaft is provided with a conventional member used for preventing the axial slide of the shaft tube. The utility model has the advantages of simple structure, convenient installation, raw material saving, etc. The utility model is especially suitable for being installed and used on bicycles.

Description

Cycle pedal

The utility model belongs to bicycle pedal, is meant a kind of central siphon and the assembling of axle one especially, is suitable for the bicycle pedal that uses on the various bicycles.

The cooperation of bicycle pedal axle and central siphon at present is generally pearl bowl shaped steel body structure, dependence is arranged on ball between central siphon and the axle and lubricating oil relatively rotating when finishing axle and central siphon and working, the pedal of said structure exists service life short (with high charcoal steel or low charcoal steel axle, bowl stack-mounted pedal service life be 6-12 month or 5 days).Ball easily seals in central siphon and causes that the rotation of pedal axle is ineffective, and waste of raw materials is big, a technical deficiency such as installation and inconvenient maintenance.

The purpose of this utility model is to provide a kind of bicycle pedal, central siphon and the steel pedal axle sleeve dress bearing fit made with non-metallic material, and be provided with in pedal axle one end and prevent that central siphon from doing the deficiency that conventional in axial sliding member overcomes prior art.

Integral structure of the present utility model is:

A kind of bicycle pedal is arranged at the bar shaped

catch

2,3 at pedal axle both ends by pedal axle 1, and the rubber block 4 that is anchored between the bar shaped catch is formed with the central siphon 5 that surrounds pedal axle periphery; Central siphon and pedal axle sleeve dress bearing fit, one end of pedal axle pass on the catch 2 opening with turn bar 6 and be connected, the other end of pedal axle is equipped with the conventional member 7 that prevents that central siphon from axially moving, central siphon cooperates with the catch at its both ends is concavo-convex, and the cross section is that the rubber block of rectangle is fastening with the baffle plate two ends respectively.

The profile of central siphon of the present utility model and material are: central siphon is the bigger garden tubular of both ends diameter of section, and central siphon is main manufactured materials with nonmetallic rigidity material, as polyamide.

Accompanying drawing of the present utility model has:

Fig. 1 is a structure diagram of the present utility model.

Fig. 2 is running condition figure of the present utility model.

Accompanying drawing has provided embodiment of the present utility model, in conjunction with the accompanying drawings embodiment of the present utility model is described as follows:

Integral structure of the present utility model is as shown: central siphon is that main material is made with nylon, profile is the bigger garden tubular of both ends diameter of section, central siphon one end and concavo-convex cooperation of axle, the other end setting of pedal axle prevents central siphon nut in axial sliding, central siphon and bar shaped catch concavo-convex cooperation of middle part that is arranged on its two ends, bar shaped catch two ends are respectively with the screw rod rubber block that to be fastened with two cross-sectional planes be rectangle, with to turn bar fastening, the circular open diameter on the catch is more smaller than central siphon external diameter by the circular open on the catch 8 for pedal axle one end.

The utility model is like this work: central siphon, catch and be fastened on that rubber block is that relative rotation is done in rotating shaft with the pedal axle on the catch when pin is stepped on pedal.

The obtained technological progress of the utility model is:

1, simple in structure, central siphon and the assembling of axle one have been avoided causing that because ball seals in central siphon the pedal rotation is dumb.

2, central siphon is made with nonmetallic materials, without ball and lubricating oil, saves a large amount of raw material.

3, central siphon is made take the high strength polyamide as primary raw material, rotate flexibly, and antiacid alkali, the loading and unloading installation rate is fast when assembling and maintenance, saving of work and time.

Claims

1, a kind of bicycle pedal is arranged at the bar shaped catch 2,3 at pedal axle both ends by pedal axle 1, and the rubber block 4 that is anchored between the bar shaped catch is formed with the central siphon 5 that surrounds pedal axle periphery; It is characterized in that central siphon and pedal axle sleeve dress bearing fit, one end of pedal axle pass on the catch 2 opening 8 with turn bar 6 and be connected, the other end of pedal axle is equipped with the conventional member 7 that prevents that central siphon from axially moving, central siphon cooperates with the catch at its both ends is concavo-convex, and the cross section is that the rubber block of rectangle is fastening with the catch two ends respectively.

2, bicycle pedal according to claim 1 is characterized in that central siphon is the garden tubular of both ends slightly larger in diameter, and central siphon is main manufactured materials with nonmetallic rigidity material, as polyamide.
