Abstract
The utility model discloses an overturn brake handle of a bicycle. The brake handle comprises a hand brake, a brake cable, a shaft sleeve and a bicycle crossbar; the hand brake is connected with the brake cable, and the hand brake is connected with the shaft sleeve through a rotating shaft; and the shaft sleeve is of a hollow structure and sleeved on the bicycle crossbar; and the overturn brake handle is characterized in that the shaft sleeve is locked with the bicycle crossbar through a quick release member. The quick release member comprises an eccentric wheel and a screw rod, the eccentric wheel is of an annular structure with a circular hole, the distance from the annular periphery to the circular hole is varied in an equidifferent way, and the screw rod is connected with the eccentric wheel through a rotating shaft. Compared with the prior art, the shaft sleeve is locked with the bicycle crossbar through the quick release member, so that the folding effect of the bicycle is better, and the situation that the exposure of the brake handle can pull articles can be avoided.
Description
Technical field
The utility model relates to bicycle manufacturing technology field, particularly relates to a kind of bicycle upset brake lever.
Background technology
The brake lever that bicycle is installed need be fixed on the bicycle cross handle, relatively Chang Yong way is that rim brake is connected with the axle sleeve rotating shaft, axle sleeve is enclosed within on the bicycle cross handle then, the internal diameter of axle sleeve is a bit larger tham the external diameter of bicycle cross handle, by a screw rod and nut axle sleeve is locked, make on the inwall outer wall that is attached to cross handle tightly of axle sleeve, thereby the brake lever of can holding with a firm grip when riding bicycle is realized bicycle brake.
This brake lever also can widespread usage on folding bicycle, when folding bicycle is in contraction state, because brake lever and cross handle are in locking state, can not arbitrarily adjust brake lever with respect to the position of cross handle, therefore folding bicycle is when shrinking, and brake lever becomes the obstacle that the folding bicycle cross handle shrinks; Be exposed at the brake lever of folding bicycle outside and the aesthetics that bicycle brake line has also influenced the contraction state folding bicycle outward; Bicycle brake line is exposed outside in addition, and easy and uncinus generation tractive when the carrying folding bicycle has influenced its practicality.
Summary of the invention
The purpose of this utility model is at the technological deficiency that exists in the prior art, and a kind of bicycle upset brake lever that can realize quick detach, fast-assembling is provided.
For realizing that the technical scheme that the purpose of this utility model adopts is: a kind of bicycle upset brake lever, described brake lever comprises rim brake, brake cable, axle sleeve and bicycle cross handle; Described rim brake is connected with brake cable, and rim brake is connected with the axle sleeve rotary shaft; Described axle sleeve is hollow structure, is enclosed within on the bicycle cross handle, it is characterized in that axle sleeve is by Fast detachable unit and the locking of bicycle cross handle.
Described Fast detachable unit comprises eccentric wheel, handle and screw rod, and described eccentric wheel center is provided with circular hole, and eccentric wheel is connected with the screw rod twisted axis by circular hole, and described handle is captiveed joint with eccentric wheel.
Described handle is the duck tongue shaped structure.
Compared with prior art, the beneficial effects of the utility model are: when folding bicycle was in deployed condition, Fast detachable unit made axle sleeve and cross handle be in locking state, and the rim brake of holding with a firm grip can be realized bicycle brake; When folding bicycle is in contraction state, the rotation Fast detachable unit, axle sleeve and cross handle no longer are locking states, and brake lever is rotated to behind the correct position cycle Fast detachable unit again, brake lever can be locked at correct position; Therefore, axle sleeve makes the folding effect of bicycle better by the locking of Fast detachable unit and bicycle cross handle, avoided brake lever expose may the tractive article situation take place.
Description of drawings
Figure 1 shows that bicycle brake handle and cross handle locking state structural representation;
Brake lever rotational structure scheme drawing when Figure 2 shows that the bicycle brake handle with the non-locking state of cross handle.
Among the figure: the 1st, rim brake, the 2nd, brake cable, the 3rd, axle sleeve, the 4th, cross handle, the 5th, eccentric wheel, the 6th, screw rod.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Embodiment: as shown in Figure 1, a kind of bicycle upset brake lever, described brake lever comprises rim brake 1, brake cable 2, axle sleeve 3, bicycle cross handle 4 and Fast detachable unit; Described rim brake 1 is connected with brake cable 2, and rim brake 1 is connected with axle sleeve 3 rotary shafts; Described axle sleeve 3 is hollow structure, is enclosed within on the bicycle cross handle 4, it is characterized in that axle sleeve 3 is by Fast detachable unit and 4 lockings of bicycle cross handle.
Described Fast detachable unit comprises eccentric wheel 5, screw rod 6 and handle, and described eccentric wheel 5 centers are provided with circular hole, and described eccentric wheel 5 is connected with screw rod 6 twisted axis by circular hole, and described handle is captiveed joint with eccentric wheel 5.
Described handle is the duck tongue shaped structure.
When pulling the handle of Fast detachable unit, eccentric wheel 5 rotates, and the distance of the outer thoughtful circular hole of annular of eccentric wheel 5 just can change, thereby causes axle sleeve 3 and bicycle cross handle 4 to be in the variation of locking state and non-locking state.
As shown in Figure 1, when folding bicycle was in deployed condition, Fast detachable unit made axle sleeve 3 and cross handle 4 be in locking state, and the rim brake 1 of holding with a firm grip can be realized bicycle brake; As shown in Figure 2, when folding bicycle is in contraction state, the rotation Fast detachable unit, axle sleeve 3 no longer is locking state with cross handle 4, and brake lever is rotated to behind the correct position cycle Fast detachable unit again, brake lever can be locked at correct position; Therefore, axle sleeve 3 makes the folding effect of bicycle better by 4 lockings of Fast detachable unit and bicycle cross handle, avoided brake lever expose may the tractive article situation take place.
The above only is preferred implementation of the present utility model; should be noted that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
