Abstract
A combined mechanism of a pedal and a crank of a bicycle comprises a pedal, a crank and a bearing. The pedestal comprises a pedal spindle and a pedal plate, and the pedal spindle and the pedal plate are fixed into an integral structure and cannot rotate or slide. The crank comprises a chain wheel, a pedal arm and a bearing set, wherein one end of the pedal arm is used for fixedly connecting with the chain wheel while the other end of the pedal arm is used for receiving the bearing seat, and a bearing whose diameter is larger than 20 mm can be mounted. According to the combined mechanism provided by the utility model, the pedal spindle and the pedal plate of the pedal are fixed, a larger space on the crank can be provided for mounting the bearing, and the bearing whose diameter is larger than 20 mm can be mounted, thereby raising durability of the pedal.
Description
Technical field
The utility model relates to bicycle accessories, particularly the combination mechanism of a kind of bicycle pedals and crank.
Background technology
Ordinary bicycle is foot-operated, is installed on crank by the screw on pedal spindle, and pedal spindle is taked to be fixedly connected with crank, not rotatable, and can relatively rotate between pedal spindle and stretcher, moves ahead thereby pedal bicycle.In order to reduce the sliding resistance between pedal spindle and stretcher, generally between pedal spindle and stretcher, bearing is installed.Owing to limited by foot-operated size dimension, therefore, this bearing can not be too large, and bearing diameter is generally less than 20mm, and because bearing is less, bearing load is larger, and bearing is easy to damage, and causes foot-operated also easily damage.Traditional foot-operated and combination mechanism of crank can not meet the requirement with stronger holding capacity.
Utility model content
For above-mentioned problems of the prior art, the purpose of this utility model is to provide the combination mechanism of a kind of bicycle pedals and crank.
In order to realize above-mentioned utility model object, the technical solution adopted in the utility model is as follows:
A combination mechanism for bicycle pedals and crank, is characterized in that, described combination mechanism comprises: foot-operated, and crank, bearing, wherein,
Described foot-operated comprise pedal spindle, stretcher; Between described pedal spindle and stretcher, be fixing integral structure, can not rotational slide between pedal spindle and stretcher;
Described crank comprises the sprocket wheel, pedal arm, the bearing seat that are rotatably mounted; One end and the sprocket wheel of described pedal arm are affixed, and the other end of described pedal arm holds bearing seat; Described bearing seat can be installed the bearing that diameter is greater than 20mm.
Further, described integral type is foot-operated is made up of metal or hard plastic material.
Further, described integral type is foot-operated is that tape is foot-operated and self-locking is foot-operated.
Further, the foot-operated stretcher of described integral type is with tooth.
The bicycle pedals that the utility model provides and the combination mechanism of crank, fix foot-operated pedal spindle and stretcher, provides larger space for bearing is installed simultaneously, and its bearing diameter can be greater than 20mm, has improved foot-operated durability.

The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with embodiment and accompanying drawing, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
The specific embodiment of the present utility model is exactly the connection mode for the combination mechanism of bicycle pedals of the prior art and crank, makes bearing size limited and cause the poor and improvement made of combination mechanism durability foot-operated and crank.Below the specific embodiment of the present utility model is described in detail.
Fig. 1 is a kind of schematic diagram of bicycle pedals.Fig. 2 is a kind of schematic diagram of bicycle crank.
As shown in Figure 1, bicycle pedals of the present utility model (4), comprises pedal spindle (41), stretcher (42), when installation, pedal spindle (41) is fixedly connected with stretcher (42), becomes integral structure.In the time that bicycle is advanced, integral type is foot-operated can bear larger load, has strengthened foot-operated stability.
As shown in Figure 2, the crank of bicycle of the present utility model (1), comprises sprocket wheel (11), the pedal arm (12) of crank and the bearing seat (13) of crank of crank.The sprocket wheel (11) of described crank is installed in rotation on cycle frame by the axle sleeve on vehicle frame and bearing, one end of pedal arm (12) and sprocket wheel (11) are affixed, and the other end is used for holding bearing seat (13).
Fig. 3 is the schematic diagram of a kind of bicycle pedals and crank assembling.Fig. 4 is the schematic diagram of the combination mechanism of a kind of bicycle pedals and crank.
As shown in Figure 3 and Figure 4, the pedal spindle (41) of integral type foot-operated (4) is inserted to bearing hole, make to ride the stretcher (42) of (4) perpendicular to sprocket wheel (11), foot-operated (4) are by bearing (3) connecting crank (1), thus the combination mechanism of formation foot-operated (4) and crank (1).While installing and using, because having larger space, the pedal arm in crank (1) (12) one end holds bearing seat (11), it can install the bearing (3) that diameter is greater than 20mm, therefore, advance in process at bicycle, foot-operated (4) can bear larger load with the combination mechanism of crank (1), improve the durability of Liao Gai mechanism.
Described integral type foot-operated (4) in use, can be made by metal or hard plastic material, can be that tape is foot-operated and self-locking foot-operated, and object based on anti-skidding, the stretcher (42) of described integral type foot-operated (4) can be with tooth.
These are only preferred embodiment of the present utility model, be not used for limiting practical range of the present utility model; If do not depart from spirit and scope of the present utility model, the utility model is modified or is equal to replacement, all should be encompassed in the middle of the protection domain of the utility model claim.
