Abstract
The utility model discloses a foot pedal which comprises a foot pedal body and a center shaft assembly plugged on the foot pedal body. The center shaft assembly comprises a center shaft, a first shaft sleeve, ball bearings, a second shaft sleeve and a fixing ring. A shaft shoulder is arranged at the left end of the center shaft. The first shaft sleeve, the ball bearings, the second shaft sleeve and the fixing ring are sequentially sleeved on the center shaft from right to left, and the fixing ring abuts against the shaft shoulder. A third shaft sleeve is sleeved at the right end of the center shaft. The fixing ring is provided with a stepped hole with the right side large and the left side small, and the large diameter end of the fixing ring is provided with an inner thread which is adaptive to an outer thread at the left end of the foot pedal body. According to the foot pedal, the fixing ring with the inner hole of a stair structure is used, the fixing ring is connected to the foot pedal body through the outer thread, and meanwhile the foot pedal body is formed by pressure casting. Thus, materials are saved, and the overall installation of the foot pedal is made to be more convenient.
Description
Technical field
The utility model relates to bicycle, is specifically related to stretcher.
Background technology
Existing various manpower bicycle is riding instead of walk and short-haul vehicle of commonly using of people, wherein, in the prior art, the making of the stretcher of bicycle is because part is too many, so its complex structure is processed loaded down with trivial detailsly, involves great expense, simultaneously the center shaft of stretcher and stretcher body be connected to the negative thread connection mode, caused very large inconvenience to the installation of stretcher integral body.
The utility model content
Technical problem to be solved in the utility model is that the stretcher that solves bicycle is installed inconvenient problem.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts provides a kind of stretcher, comprise stretcher body and the central axis component that is inserted on the described stretcher body, described central axis component comprises center shaft, the first axle sleeve, ball bearing of main shaft, the second axle sleeve and set collar, the left end of described center shaft is provided with the shaft shoulder, described the first axle sleeve, ball bearing of main shaft, the second axle sleeve and set collar are sleeved on the described center shaft from right to left successively, and described set collar and the described shaft shoulder offset, the right-hand member of described center shaft is set with the 3rd axle sleeve, described set collar has right large left little stepped hole, and the larger diameter end of described set collar is provided with the negative thread adaptive with described stretcher body left end outside thread.
In such scheme, described set collar is circular.
In such scheme, the profile of described set collar is polygon.
In such scheme, be laid with many axial fins on the outer circumference surface of described set collar.
In such scheme, the right-hand member of the described shaft shoulder is the circular conical surface platform.
In such scheme, described ball bearing of main shaft is two, is arranged side by side.
The utility model, adopting endoporus is the set collar of hierarchic structure, is connected on the stretcher body by outside thread, and the stretcher body is so not only saved material by die cast simultaneously, and it is convenient that the installation of stretcher integral body also becomes.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is decomposition texture schematic diagram of the present utility model;
Fig. 3 is the structural representation of central axis component of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is made detailed explanation.
As shown in Figure 1 and Figure 2, the utility model provides a kind of stretcher, comprises stretcher body 1 and central axis component.
Again in conjunction with Fig. 3, central axis component comprises center shaft 6, the first axle sleeve 3, ball bearing of main shaft 4, the second axle sleeve 5 and set collar 7, the left end of center shaft 6 is provided with the shaft shoulder, the first axle sleeve 3, ball bearing of main shaft 4, the second axle sleeve 5 and set collar 7 are sleeved on the center shaft 6 from right to left successively, and set collar 7 offsets with the shaft shoulder, the right-hand member of the shaft shoulder is the circular cone table top, the right-hand member of center shaft 6 is set with the 3rd axle sleeve 2, set collar 7 has right large left little stepped hole, and the larger diameter end of set collar 7 is provided with the negative thread adaptive with stretcher body 1 left end outside thread, central axis component is inserted in the stretcher body 1, and is fixed by set collar 7.
Set collar 7 is circular, and is laid with many axial fins on the outer circumference surface of set collar 7, so that install.The profile of set collar 7 also can be polygon.
In this case, ball bearing of main shaft 4 is two, is arranged side by side.
The utility model, adopting endoporus is the set collar of hierarchic structure, is connected on the stretcher body by outside thread, and the stretcher body is so not only saved material by die cast simultaneously, and it is convenient that the installation of stretcher integral body also becomes.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, all fall within the protection domain of the present utility model.
