Specific implementation mode
The utility model is described in further detail with reference to the accompanying drawings and detailed description：
As shown in Figures 1 to 9, the utility model bicycle brake is cross-placed on the predeterminated position of a wheel rim 1, including：
One pedestal 10, the upper end is fixed in the predeterminated position of a cycle frame with a fixed link 101, and has extended downwardly
First adjutage 11 and the second adjutage 12, and first adjutage 11 and the second adjutage 12 are respectively correspondingly located at the wheel rim
1 both sides；One first clamp arm 20, through the first perforation 201 for having a strip, which is formed with recessed
Cambered surface 202 and another end periphery are formed with convex globoidal 203, and 20 lower end of the first clamp arm is hubbed at 11 lower end of the first adjutage, and thereon
The side at end is consolidated with a fixing piece 21 and a conducting wire orifice 22 respectively with avris, wherein the side of 20 upper end of the first clamp arm
Side is equipped with a screw hole 23, in the conducting wire orifice 22 there is a thread segment 221, the conducting wire orifice 22 to be set by 221 spiral shell of thread segment
It is fixed on the screw hole 23；One second clamp arm 30, through the second perforation 301 for having a strip, 301 one end peripheries of the second perforation
It is formed with cancave cambered surface 302 and another end periphery is formed with convex globoidal 303,30 lower end of the second clamp arm is hubbed under second adjutage 12
End, and the upper end is pivoted with a pulley 31 in the side of the identical fixing piece 21；Two brake shoes 40, one side are defined as compressing face
401 and its another side be convexly equipped with convex globoidal 402, this compresses 401 system of face and is coated with a rubber layer 43, and is combined on the convex globoidal 402
There is an external thread rod 41, two brake shoes 40 are respectively by the external thread rod 41 by first clamp arm 20 and the second clamp arm 30
After side is fed through the first perforation 201 of first clamp arm 20 and the second perforation 301 of the second clamp arm 30, and respectively with a locking part
42 are screw-locked on the external thread rod 41, make two brake shoes 40 respectively in connection in first clamp arm 20 and the second clamp arm 30,
In, which is formed with cancave cambered surface 421,421 system of cancave cambered surface against this first perforation 201 with second perforate 301
Convex globoidal 203,303, and 402 system of convex globoidal of two brake shoes 40 against this first perforation 201 with second perforate 301 it is recessed
Cambered surface 202,302.
Wherein, two resetting springs 50 be respectively arranged between 11 pivot points of first clamp arm 20 and the first adjutage and
Between 12 pivot points of second clamp arm 30 and the second adjutage, and two 50 one end of resetting spring is made to be butted on the first clamp arm respectively
20,30 side of the second clamp arm and another end are butted on the first adjutage 11,12 side of the second adjutage.
The operative scenario of the utility model is described as follows below：
It first, will after bicycle brake being directly fixed in the predeterminated position of cycle frame by the fixed link 101
One brake cable 60 from first clamp arm 20 from the outer conducting wire orifice 22 being fed through toward interior direction in first clamp arm 20, then cover around
It is returned after crossing the pulley 31 of second clamp arm 30, which is fixed on the fixing piece 21 of first clamp arm 20.
Therefore, when rider's execution brake acts and pulls the brake cable 60, first clamp arm 20 and the second clamp arm 30 can be relatively same
When inner swing, allow the brake shoes 40 of first clamp arm 20 and the second clamp arm 30 that can push against the both sides of the wheel rim 1 respectively.And when one
After the action of denier brake and when loosening the brake cable 60, first clamp arm can be allowed because the elastic force of resetting spring 50 acts on
20 and second clamp arm 30 can swing back the form more opened originally, and the separate wheel rim 1 outwardly relatively, avoid the brake shoes 40
Continue the two side contacts frictions with the wheel rim 1.
However, when the angle difference between 1 both sides of two brake shoes 40 and wheel rim, two brake shoes 40 are only with part face
Product clamps 1 both sides of wheel rim, causes to lead to the ineffective of brake, therefore, can revolve the locking part 42 on the external thread rod 41
Pine puts the brake shoes 40 using its convex globoidal 402 and the cancave cambered surface 202,302 of first clamp arm 20 or the second clamp arm 30
Dynamic, the brake shoes 40 to be adjusted and 1 side of wheel rim are in after best cramping angle, then by the locking part 42 on the external thread rod 41
It screws, and the cancave cambered surface 421 of the locking part 42 is made to be closely against the convex globoidal 203,303 of first clamp arm 20 or the second clamp arm 30,
Meanwhile the convex globoidal 402 of two brake shoes 40 also against this first perforation 201 or second perforation 301 cancave cambered surface 202,302,
Complete the angle adjustment of the brake shoes 40.
The regulating structure for brake of the utility model bicycle brake, the wheel rim 1 produced by each production dealer
The angle of both sides is differed with width, and two brake shoes 40 can be made to swing and make angle adjustment above and below, to correspond to 1 both sides of wheel rim
Angle, allow brake shoes 40 to clamp wheel rim 1 with Maximum Contact area, reach best braking effect, can be carried for rider
High braking ability, safety and practicability.
In conclusion the utility model can effectively solve the scarce plain of the prior art, and can be common in technical field
Skill understands and implements easily that above-described embodiment is only a preferred embodiment of the utility model, when cannot be with it
Limit the range of this creation implementation；All should still it belong to according to equivalent changes and modifications made by this creation claim generally
