Description
Technical field
The utility model is related to a kind of castor.
Background technology
The general castor with brake function, the wheel body being substantially articulated in by a body with one on body is constituted,
The drive block provided with a brake shoes and control brake shoes activity, is moved down by drive block and interlocks and move down between body and wheel body
Brake shoes suppresses wheel body, to reach brake function, move down press more tight then braking effect is better.In use, user
Always can unconsciously think that brake is not tight enough, continuation is down stepped on strength, stepped in subconsciousness more tight then braking effect is better, it is long
After phase use, brake shoes is easily deformed or even damaged, and reduces service life.
The content of the invention
The utility model provides a kind of simple in construction, service life length, the castor with brake limit function.
The utility model solves the technical scheme that its technical problem used：
A kind of castor, including wheel carrier, the wheel being hinged on wheel carrier and the braking mechanism being arranged on wheel carrier, it is described to stop
Mechanism of car includes that the pin in the briquetting, the linkage rack of drive briquetting motion and driving linkage rack motion of wheel surface can be suppressed
Pedal, the both sides up and down at the middle part of the pedal are respectively equipped with upper and lower cam-type arc-shaped side, and the linkage rack is provided with difference
The upper and lower projection corresponding with upper and lower cam-type arc-shaped side, the linkage rack is arranged on wheel carrier, the upper and lower cam-type arc
Shape side is provided with and is respectively equipped with upper and lower stopper slot.
In the utility model, it is hinged in the middle part of the pedal in rotating shaft.
In the utility model, the side wall of the wheel carrier, which is provided with, is available for the open slot that linkage rack is passed through, the linkage rack
One end bending is passed through and is connected with briquetting out of open slot, and the other end of linkage rack is located at wheel carrier outer wall and is connected in rotating shaft.
In the utility model, the pedal is provided with forward and backward pedal, and the upper surface of the forward and backward pedal is fluctuating
Shape.
The beneficial effects of the utility model are：The utility model is limited braking mechanism using two mechanical gears
Position, after pedal steps on forward position, briquetting has just been pressed in wheel surface, and wheel is compressed, and plays braking action, simultaneously
Upper raised or lower convexity is just stuck in upper limit position groove or lower limit groove, and pedal and briquetting can not continue to move down, and briquetting will not
Continue to suppress wheel surface, damage will not be caused to wheel surface, further, the position sense of limited impression is obvious, and user is non-
Chang Rongyi can just feel in place, will not continue to firmly step on pedal, extend the service life of castor.
Brief description of the drawings
The utility model is further illustrated with embodiment below in conjunction with the accompanying drawings：
Fig. 1 is structural representation of the present utility model；
Fig. 2 is Fig. 1 left view.
Embodiment
Referring to figs. 1 to Fig. 2, a kind of castor that the present embodiment is provided, including wheel carrier 1, the wheel 2 that is hinged on wheel carrier 1
And the braking mechanism on wheel carrier 1 is arranged on, the braking mechanism includes to suppress in the briquetting 3 on the surface of wheel 2, with dynamic pressure
The pedal 5 that the linkage rack 4 and driving linkage rack 4 that block 3 is moved are moved, the difference of both sides up and down at the middle part of the pedal 5
Provided with upper and lower cam-type arc-shaped side 6,7, the linkage rack 4 is provided with corresponding with upper and lower cam-type arc-shaped side 6,7 respectively
Upper and lower raised 8,9, described upper and lower raised 8,9 can both be integrally formed with linkage rack 4, can also pass through welding or the side riveted
Formula is fixed on linkage rack 4, and the linkage rack 4 is arranged on wheel carrier 1, and the upper and lower cam-type arc-shaped side 6,7 is provided with difference
Provided with upper and lower stopper slot 10,11, when pedal 5 is rotated forward, then convex wheeled arc-shaped side 6 is contacted with upper raised 8, and
Raised 8 are constantly raised in rotary course, linkage linkage rack 4 and briquetting 3 are up moved, until upper raised 8 enter upper limit position groove
In 10, so that releasing of brake；When pedal 5 is reversely rotated, then cam-type arc-shaped side 7 is descended to be contacted with lower convexity 9, and in rotation
During constantly drive lower convexity 9 to move down, linkage linkage rack 4 and briquetting 3 move down, until lower convexity 9 enters lower limit
In the groove 11 of position, while briquetting 3 is pressed on the surface of wheel carrier 1, so as to play braking effect.
As preferred embodiment, for the ease of installing, accessory needed for reducing, the middle part of the pedal 5 is hinged on
In rotating shaft 12, further, touch on the brake for convenience, prevent sole from skidding, the pedal 5 is provided with forward and backward pedal 14,15,
The upper surface of the forward and backward pedal 14,15 is undulations.
In the present embodiment, the side wall of the wheel carrier 1 is provided with and is available for the open slot 13 that linkage rack 4 is passed through, the linkage rack 4
