Abstract
The utility model discloses an electric bicycle crank with an adjustable angle, which comprises a bicycle crank (1); the larger end of the bicycle crank (1) is matched with a central shaft through a square hole; a quickly detachable component is arranged on the bicycle crank (1); the quickly detachable component comprises an earring-type screw rod (5) and a cam (3); the larger end of the bicycle crank (1) is provided with a through hole (2); one end of the through hole (2) is a screw hole; one end of the earring-type screw rod (5) is connected onto the bicycle crank (1) by a nut through the through hole (2) on the larger end of the bicycle crank; and the other end of the earring-type screw rod (5) is connected with the cam (3) through a shaft pin (6) and a gasket (4). The electric bicycle crank with the adjustable angle is a detachable and rotatable crank, has a simple structure and is convenient to operate, so that the possibility of the occurrence of a series of risks can be effectively prevented, and a certain anti-theft role can be played.
Description
Technical field
The utility model relates to bicycle crank, is specifically related to a kind of Electrical Bicycle crank that can adjusting angle.
Background technology
When riding battery-driven car, on if pin does not step down in and rides, then can make the foot-operated light condition that is in, therefore foot-operated can crank is foot-operated to be in one and to be unfavorable for very much the seat of riding because static unbalance, jolting dynamically the time make---ride vertical one on the other seat.And, the dangerous possibility that takes place in the time of can increasing by bike under these circumstances.Particularly under turning and the uneven situation in roadside, foot-operated crank becomes the vertically meeting of placement scratch road surface, hook foreign matter, this takes place suddenly to produce very serious accident under unguarded situation, so in order to reduce the danger that this defective is brought, a kind of crank of angle adjustable just plays crucial effects.
Summary of the invention
The purpose of this utility model is: a kind of Electrical Bicycle crank that can adjusting angle is provided, be a kind of detouchable, rotatable crank, simple in structure, easy to operate, a series of dangerous possibilities that take place can be effectively prevented, certain antitheft effect can also be played.
Technical solution of the present utility model is: comprise bicycle crank, the stub end of bicycle crank cooperates axis through square hole, it is characterized in that: the quick detach assembly is installed on the bicycle crank, the quick detach assembly comprises earrings formula screw rod and cam, the stub end of bicycle crank has a through hole, a wherein end of through hole is a screw, one end of earrings formula screw rod is connected on the bicycle crank through nut by the through hole of the stub end of bicycle crank, and the other end of earrings formula screw rod connects cam through pivot pin, pad.
During assembling, earrings formula screw rod is passed the through hole of the stub end of bicycle crank and fix with nut, rotating cam, whether observe can be at two the limit fixed cranks and the adjust crank of rotation, as not all right, adjustment nut; During use, earrings formula screw rod is fixed in the through hole of stub end of bicycle crank, and the gap between rotating cam dwindles can tightly be pressed on the axis bicycle crank, such and common foot-operated crank is as broad as long, does not drive battery-driven car by manpower when having electricity; When battery-driven car had enough electric power, releasing cam was adjusted angle, made bicycle crank be placed on a side about the car body symmetry, allowed the foot-operated electric bicycle that is placed on be to hang down below on one's body and no longer.
The utlity model has following advantage: 1, the gap that rotates the two that dwindles bicycle crank by the cam on the earrings formula screw rod makes bicycle crank be pressed on the axis of car body and loosens and come adjusting angle, has both reduced dangerous generation, increases aesthetic property again; 2, foot-operatedly be able to " hiding " through behind the rotary folding, thereby it is comfortable to have brought for people when riding, pin can arbitrarily be put, and prevents from simultaneously foot-operatedly when turning to bump with ground, avoids causing the damage of battery-driven car, further prevents to fall down and accidents caused; 3, when battery-driven car does not have electricity, emit foot-operated, continue to ride by manpower, simple for structure attractive in appearance.
Description of drawings
Fig. 1 is a bicycle crank scheme drawing of the present utility model.
Fig. 2 is a quick detach assembly scheme drawing of the present utility model.
Among the figure: 1 bicycle crank, 2 through holes, 3 cams, 4 pads, 5 earrings formula screw rods, 6 pivot pins.
The specific embodiment
As shown in Figure 1, 2, comprise bicycle crank 1, the stub end of bicycle crank 1 cooperates axis through square hole, it is characterized in that: the quick detach assembly is installed on the bicycle crank 1, the quick detach assembly comprises earrings formula screw rod 5 and cam 3, the stub end of bicycle crank 1 has a through hole 2, a wherein end of through hole 2 is screws, one end of earrings formula screw rod 5 is connected on the bicycle crank 1 through nut by the through hole 2 of the stub end of bicycle crank, and the other end of earrings formula screw rod 5 connects cam 3 through pivot pin 6, pad 4.
During assembling, earrings formula screw rod 5 is passed the through hole 2 usefulness nuts of the stub end of bicycle crank 1 and fix, rotating cam 3, whether observe can be at two the limit fixed cranks and the adjust crank of rotation, as not all right, adjustment nut; During use, earrings formula screw rod 5 is fixed in the through hole 2 of stub end of bicycle crank 1, and the gap between rotating cam 3 dwindles can tightly be pressed on the axis bicycle crank, such and common foot-operated crank is as broad as long, does not drive battery-driven car by manpower when having electricity; When battery-driven car had enough electric power, releasing cam 3 was adjusted angle, made bicycle crank 1 be placed on a side about the car body symmetry, allowed the foot-operated electric bicycle that is placed on be to hang down below on one's body and no longer.
