Abstract

The utility model relates to a pedal lever, particularly a bicycle pedal lever which is arranged on a bicycle, wherein, the pedal lever can increase structural strength and prevent the bicycle from deforming caused by impact. The utility model has the improvement structure of the bicycle pedal lever that the inner part of the pedal lever is provided with a polygonal hollow part; a solid pedal lever wall with different thickness is formed between the outer circumference and the hollow part of the pedal lever; the thinnest part of the thickness of the solid pedal lever wall is arranged at an angle of a polygon; the thickest part of the thickness is arranged at the center section position of each side of the polygon. The utility model prevents deformation or sag caused by impacting various barriers or dwarf walls, etc.

Description

The prop stand for bicycle treadle improves structure

Technical field

The utility model relates to a kind of foot-driven lever, and particularly a kind of being installed in can increase the prop stand for bicycle treadle that structural strength avoids it to be out of shape because of bump on the bicycle.

Background technology

The prop stand for bicycle treadle of prior art as shown in Figure 1; this foot-driven lever 1 is cylindric; inside is hollow; one end 2 usefulness nuts 3 are fixed on the hind axle, generally perform to make often of bicycle to fly the action that height undercuts, even draw high to parapet and run quickly or the like; regular meeting takes place during the various action that may hit foot-driven lever 1; cause the foot-driven lever 1 of this hollow to be hit easily being in depression 4 or distortion, causing usually has the many places depression on the foot-driven lever 1, and outward appearance is not beautiful.

The utility model content

The purpose of this utility model is to provide a kind of prop stand for bicycle treadle that can the structural strength of increase own to improve structure.

For the technical solution adopted in the utility model that achieves the above object as follows: the prop stand for bicycle treadle improves structure, its foot-driven lever inside has a polygon hollow space, form the entity treadle wall of a variable thickness between foot-driven lever outer shroud and the hollow space, the thinnest part of this entity treadle wall thickness is positioned at the angle of polygon, and the thick of thickness is positioned at the middle section on each limit of polygon.

The utility model has compared with prior art been avoided because of hitting distortion or the depression that various obstacles or parapet etc. produce.

Description of drawings

Fig. 1 is the prop stand for bicycle treadle structural representation of prior art.

Fig. 2 is a three-dimensional decomposition texture scheme drawing of the present utility model.

Fig. 3 is the structural representation of the utility model specific embodiment.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail: as Fig. 2, shown in Figure 3, the utility model is the foot-driven lever 1 in-to-in hollow space in prior art, what be designed to see from the side is a polygon hollow bulb 10, with present embodiment, be designed to hexagon hollow bulb 10, therefore in the entity portion 12 that forms a variable thickness outside the foot-driven lever 1 between ring 11 and the hollow bulb 10, the thickness of the thinnest part 13 of this entity portion 12 (being positioned at six angles) also is slightly larger than the thickness of the foot-driven lever 1 of prior art, remainder foot-driven lever 1 thickness greater than prior art especially is a lot, as figure, thick then is positioned at the middle section on polygonal each limit.So, one increase the intensity of foot-operated pipe greatly, are difficult for producing depression or distortion when hitting obstacle or parapet; Second when hit polygonal Jiao Chu, when locating 15 as the angle, because of place, this angle 15 is to be defined by 16,17 on two limits, these both

sides

16,17 provide this place, angle 15 good support strengths, make this place, angle be not easy distortion or produce to cave in.

As seen the utility model forms a polygonal hollow space at the whole hollow space of foot-driven lever 1 in-to-in of prior art, increase its solid thickness, and the polygon frame has the function of propping up in hollow inside, makes that the foot-driven lever outside face is not easy to be out of shape or to cave in because of bump.

Claims

1. a prop stand for bicycle treadle improves structure, it is characterized in that foot-driven lever inside has a polygon hollow space, form the entity treadle wall of a variable thickness between foot-driven lever outer shroud and the hollow space, the thinnest part of this entity treadle wall thickness is positioned at the angle of polygon, and the thick of thickness is positioned at the middle section on each limit of polygon.
