A kind of directional device for wheel, the brake pedal being installed on including one between two wheels, allow operator can be by trampling a brake pedal, via the rotation of interlocking lever and the actuator of end, push the brake ring of two sides to two sides corresponding wheel clip tooth simultaneously using an elastic parts, two wheels is made to be synchronized brake.When releasing brake, then brake pedal is reversely trampled, makes the actuator of two sides that brake ring can be pushed away synchronously to the clip tooth of wheel, so synchronously release the brake of two sides wheel.Brake structure of pram provided by the invention, mechanism is easy to operate, safe and practical.
Description
Technical field
The present invention relates to a kind of carrier synchronous brake arrangements, espespecially make synchronous brake or release to stop to two sides wheel using a pedal
The carrier synchronous brake arrangement for applying to perambulator of vehicle.
Background technique
There are many kinds of the braking mechanisms for being applied to baby stroller at present, common are a kind of individual in left and right two rear-wheel
A pedal is arranged in ground, is each provided with inserted tooth in each pedal, as the rotation of pedal can enable its inserted tooth insertion rear-wheel
Brake tooth socket, whereby stops rear-wheel brake.The left and right both sides of the control mechanism of such brake point individually carry out, troublesome in poeration, especially exist
When encountering emergency, when the rear-wheel of two sides can not be checked simultaneously, it will cause trolley to shake and move, spin or topple over, cause
Baby falls and hurts.This left and right braking mechanism that can not be synchronized, be still applied at present the baby stroller that travels at a slow speed or
Travel on the baby stroller etc. on steady road surface.For travelling or travelling on more precipitous slope pavement at a relatively high speed
When, based on the considerations of safety, two rear-wheel synchronous brakes just seem important.By taking Britain as an example, they have stepped on perambulator list double
Brake is included in safety standard.
Therefore, it is necessary to invent a kind of carrier synchronous brake arrangement that can apply to perambulator to solve the above problems.
Summary of the invention

Specific embodiment
Referring to Figure 1 and Figure 2, one embodiment of directional device for wheel of the present invention is disclosed comprising have: baby-carrier framework
10, foot tube 11, wheel seat 2, wheel shaft 21, extension spring 22, pivoting part 23, wheel 3, clip tooth 31, interlocking lever 4, stopper section 41,
Brake pedal 5, stampeding section 51, actuator 6, driving inclined-plane 61, brake ring 7, by driving inclined-plane 71, retainer 72, elastic parts
8。
Directional device for wheel embodiment shown in -3 refering to fig. 1, operator can reach arranged on left and right sides using brake pedal 5
Wheel synchronous brake or the synchronous control for releasing brake.The directional device for wheel of the present embodiment is to be incorporated into a baby-carrier framework
10.Wherein baby-carrier framework 10 has an expansion and folding state.It in the present embodiment, can be the skeleton 10 of a longitudinal folding,
It include foot tube 11(include front foot pipe and rear foot tube).
The directional device for wheel of the present embodiment include a pair of of wheel seat 2, an interlocking lever 4, a brake pedal 5, an actuator 6,
One brake ring 7 and an elastic parts 8.
Wheel seat 2 is articulated in the lower end of foot tube 11, and wheel seat 2, which is equipped with a wheel shaft 21, to be run through and the unilateral or bilateral wheel 3 that is pivoted,
Clip tooth 31 is arranged in the inner side edge of middle wheel 3.In the present embodiment, clip tooth 31 is radial pillar.And 3 device of wheel
When wheel seat 2, clip tooth 31 is towards wheel seat 2 and close to wheel seat 2.In addition, being to be drawn equipped with one between each wheel seat 2 and foot tube 11
Stretch spring 22 so that the present embodiment wheel seat 2 have the effect of it is shockproof.
Interlocking lever 4 is rotatably to be articulated between two sides wheel seat 2, and stopper section 41 is arranged in the two sides of interlocking lever 4.
Refering to brake pedal 5 shown in Fig. 4, to be fixedly connected on 4 middle position of interlocking lever, brake pedal 5 has one to stop
Vehicle stampeding section 51 is supplied to operator and tramples, and then rotates the interlocking lever court clockwise or counterclockwise.
Actuator 6 is rotatably socketed on the side of interlocking lever 4, and obtains actuator 6 and 4 common rotation of interlocking lever, drive
Moving part 6 is equipped with driving inclined-plane 61 in its annular end face system.
Brake ring 7 can be rotated and slidably be socketed on the interlocking lever 4.The medial end of brake ring 7 is equipped with and actuator 6
It is opposite by driving inclined-plane 71, and the other end then extends retainer 72, and makes it adjacent to the clip tooth 31 of wheel.In this reality
It applies in example, retainer 72 is arranged to the groove engaged with clip tooth 31.
Elastic parts 8 is installed between the stopper section 41 and brake ring 7 of the interlocking lever 4, is used and is kept right to brake ring 7
The braking state of 3 clip tooth 31 of wheel, in the present embodiment, elastic parts 8 is a compressed spring.
With reference to shown in Fig. 5,6, by the combination of above-mentioned component, when not braking, brake ring 7 is driven the limitation of moving part 6 and presses
Elastic parts 8, and clip tooth 31 is made to keep certain distance, wheel 3 be freely rotated must, at this point, the driving of the actuator 6 is oblique
Face 61 and this brake ring 7 are sequence by 71 system of driving inclined-plane；And when operator is to be braked, it is to trample the brake pedal
5 brake pedal portion 51 is connected to the actuator 6 at both ends with season while rotating so that it drives interlocking lever 4 to rotate, and works as
The actuator 6 rotate when, the driving inclined-plane 61 is bonded with by driving inclined-plane 61 with rotation so that the brake ring 7 by
It is by the elastic force of elastic parts 8, brake ring 7 is mobile towards actuator 6, while the one end for making brake ring 7 have retainer 72 enters institute
The clip tooth 31 of wheel 3 is stated, and forms it into the braking state of the rotation of limiting wheel 3.
And when operator's brake to be released, then the release brake pedal portion 52 of brake pedal 5 is trampled, and make interlocking lever 4
And the actuator 6 of two sides rotates backward, at this point, by the actuator 6 61 ejection brake ring 7 of driving inclined-plane by driving inclined-plane
71, so that brake ring 7 is moved linearly and is left actuator 6, and press elastic parts 8, and then make the retainer 72 of the brake ring 7
It is detached from the clip tooth 31 of wheel 3, and reaches the effect for releasing brake.
Brake structure of pram provided by the invention, due to being provided with the brake pedal being installed among two wheels, operation
Person forward and backward can trample the brake pedal, allow an interlocking lever to go to turn the actuator at both ends, and then the brake ring of two sides is synchronous
The clip tooth for pushing or being detached from wheel to is used and achievees the effect that synchronous brake or release to brake.Sleeve mechanism is easy to operate, peace
It is complete practical.
The above disclosure is only a preferred embodiment of the invention, cannot limit the right of the present invention with this certainly
Range, therefore according to equivalent variations made by scope of the present invention patent, it is still within the scope of the present invention.
