An important components is arranged on the bicycle, i.e. bicycle brake, it is at uphill/downhill, dodge the obstacle personage, occasion does not conform to and neglects the working part that lacks when meeting traffic lights or the like, and brake failure just dangerous situation can take place, so each bicycle must have reliable, a sensitive brake working part.
The bicycle cable brake formula brake gear of prior art all is the terminations that will spur the backguy of front and back wheel braking rubber block by the handle brake lever, by rotating shaft, spur and brake bicycle by leverage, so being configured in of structure respectively has one group on the bicycle wheels, control respectively by left and right sides handle, can solve the needs of brake.
But the cable brake formula bicycle brake of prior art still has the imperfection part, still requires further improvement part.The time report arranged, people by bike runs into emergency situation and brakes rapidly in the way of fast running, because the front and back wheel stopper is asynchronous, have an accident, when front-wheel did not change prior to the trailing wheel braking, wheel was motionless earlier, and trailing wheel also has speed and impulse force, the running of trailing wheel make whole bicycle can from after forward, upwards dig, the cyclist is routed up car and the accident that creates greater casualties.People's will is can judge and corresponding reaction under general situation, still, impatiently in a great rush when, when being caught unprepared, have little time thinking and reaction accident and just take place and led to.For cyclist's personal safety, we should provide a measure reply of property safety as far as possible " just in case ".
(3) summary of the invention
The purpose of this utility model is to intend being provided at can not taking place under any situation to brake nonsynchronous a kind of brake gear before and after the cable brake formula bicycle brake.
The purpose of this utility model is solved by following technical scheme:
Synchronous brake before and after a kind of cable brake formula bicycle, comprise that the handle switch block is rotatably connected on the lock seat by bearing pin, it is characterized in that: connect two pulling blocks of offering circular groove on the described handle switch block, in circular groove, embed the cylinder lock head of two clues of forward and backward brake respectively, embed the cylinder lock head of the clue of Front brake in the wings in the circular groove.
Further, in the circular groove of the place ahead of described handle switch block, embed the cylinder lock head of the clue of back brake.
Adopt the technical program, in emergency, under any situation, two bicycle brake handles about the cyclist needn't hold again, and only need hold a handle, just can brake simultaneously, check former and later two wheels of bicycle, asynchronous braking before and after front-wheel or the trailing wheel again can not occur and thrown cyclist's contingency.Connect two pulling blocks of offering circular groove on the handle switch block described in the utility model, in circular groove, embed the cylinder lock head of two clues of forward and backward brake respectively, therefore, the handle switch block of holding with a firm grip, the cylinder lock heads of two brakings in front and back clues are tightened up simultaneously, realized the braking of wheel simultaneously, no longer had brake danger and taken place.
The beneficial effects of the utility model: the technical program can not take place to brake nonsynchronous a kind of brake gear before and after the cable brake formula bicycle brake under any situation, as long as just hold the effect that a brake handle can be realized front and back two-wheeled synchronous braking.
(4) description of drawings

Fig. 2 controls the structural representation of the front or rear brake of a side for prior art cable brake formula bicycle brake device.
Among the figure, the 1st, clue, the 2nd, lock seat, the 3rd, cylinder lock head, the 4th, pulling block, 5 bearing pins, the 6th, handle switch block.
(5) specific implementation method
Further describe structure of the present utility model below in conjunction with accompanying drawing.
Synchronous brake before and after a kind of cable brake formula bicycle, comprise that handle switch block 6 is rotatably connected on the lock seat 2 by bearing pin 5, connect two pulling blocks 4 of having offered circular groove on the described handle switch block 6, in circular groove, embed the cylinder lock head 3 of two clues 1 of forward and backward brake respectively.The handle switch block 6 of holding with a firm grip, the cylinder lock heads 3 of two brakings in front and back clue 1 are tightened up simultaneously, have realized the braking of wheel simultaneously, no longer have brake danger and have taken place.
In the circular groove of the place ahead of described handle switch block 6, embed the cylinder lock head 3 of the clue 1 of back brake, embed the cylinder lock head 3 of the clue 1 of Front brake in the wings in the circular groove.Because, the rotating pin 5 of handle switch block 6 is positioned at rear side, the rotation direction of holding handle switch block 6 backwards, cylinder lock head 3 on the pulling clue 1, because leverage, adopt the technical program, embed the cylinder lock head 3 of the clue 1 of back brake in the circular groove of the place ahead, the circular groove in the place ahead is far away from the distance of bearing pin 5, and the arm of force is long, produce earlier, reaction tension action and effect, have trickle than the circular groove that is positioned at the rear from bearing pin 5, the tightening-up time of the front and back beat of moment is poor, and tension earlier, embrace the circular groove in the place ahead, also promptly strain the clue of rear wheel brake earlier, the rotation of elder generation's braking rear-wheel, safety---the trailing wheel braking has been lived, and the responsiveness of front-wheel can only be dragged vehicle forward and skip car event can not be taken place, and these time differences are extremely trickle certainly relatively more, be moment, so additional constraint is more content to retain sovereignty over a part of the country complete.
