Abstract
The utility model relates to an area brake truckle, including the truckle frame, install the wheel on the truckle frame, footboard and brake block, be provided with ratchet and the cam of coaxial arrangement on the truckle frame between footboard and the brake block, the ratchet sets firmly the both sides at the cam, set up respectively on footboard and truckle frame with ratchet assorted power pawl and location pawl, be provided with the return spring who is connected with the footboard on the power pawl, be provided with the tension springs who is connected with the truckle frame on the pawl of location, be provided with the resilience piece that contacts with the truckle frame on the brake block, be provided with the return shell fragment that contacts with the truckle frame on the footboard. The utility model discloses simple structure, convenient to use, brake safety and stability. The footboard need be continuously do not not trampled, braking status can be kept, when relieving the brake, also only need trample the footboard once more. No matter brake or relieve the action of brake, all accord with very much the regular operation custom, convenient and practical.
Description
Technical field
This utility model relates to castor brake technique field, especially relates to a kind of strap brake castor.
Background technology
Existing caster brake system is typically made up of pedal and brake block, and pedal lower surface is provided with projection.When needing brake, step on pedal, make projection be compressed tightly against on castor by brake block, stop vehicle wheel rotation.This brake modes, needs to be continuously stepping on pedal to extreme position, limits legs and feet the most movable.And when releasing braking state, need upwards jack-up pedal, and make projection and castor depart from, this action and routine operation custom are runed counter to, operation inconvenience.Additionally, if the equipment being arranged on castor shakes, projection easily automatically springs open, and makes castor be in non-braking state, causes equipment to move, causes causing danger.
Summary of the invention
This utility model provides a kind of strap brake castor, it is therefore intended that solve existing caster brake system inconvenient operation, unsafe problem of braking.
For achieving the above object, this utility model can take following technical proposals:
Strap brake foot described in the utility model is taken turns, including foot wheel carrier, it is arranged on the wheel on described foot wheel carrier, pedal and brake block, the ratchet being coaxially mounted on foot wheel carrier and cam it is provided with between described pedal and brake block, described ratchet is installed in the both sides of described cam, the power ratchet matched with described ratchet and detent are separately positioned on pedal and foot wheel carrier, it is provided with, on described power ratchet, the return spring being connected with pedal, the tension spring being connected with foot wheel carrier it is provided with on described detent, the resilience sheet contacted with foot wheel carrier it is provided with on described brake block, the return shell fragment contacted with foot wheel carrier it is provided with on described pedal.
The strap brake castor that this utility model provides, simple in construction, easy to use, braking safe is stable.It is not required to be continuously stepping on pedal, braking state can be kept；When releasing brake, the most only need pushes pedals again.Either brake or the action of releasing brake, meets routine operation custom the most very much, convenient and practical.Owing to therefore pedal can need not be continuously stepping on self-return, eliminate the phenomenon that legs and feet are limited, save manpower.Under non-braking state, brake block, under the effect of resilience sheet, can automatically disengage wheel, makes the wheel can be freely rotatable.Additionally, detent can make ratchet position, so that cam continuous contact wheel under braking state, form braking locking state, it is to avoid unexpected vibration causes brake releasing to cause to cause danger.

Detailed description of the invention
As shown in figures 1 to 6, strap brake castor described in the utility model, including foot wheel carrier 1, the wheel 2 being arranged on foot wheel carrier 1 by rotating shaft, and the pedal 3 that is hinged above wheel 2 side and brake block 4；It is welded with the resilience sheet 11 contacted with foot wheel carrier 1 on brake block 4, pedal 3 is welded with the return shell fragment 12 contacted with foot wheel carrier 1.Additionally, be also equipped with coaxially connected ratchet 5 and cam 6 on foot wheel carrier 1 between pedal 3 and brake block 4, ratchet 5 is installed in the both sides of cam 6, rotates simultaneously or stop；Being evenly equipped with 8 gear teeth on this ratchet 5, cam 6 outward appearance is square structure.Various location at ratchet 5 is provided with matched power ratchet 7 and detent 8, and wherein, power ratchet 7 is installed in the bottom surface of pedal 3, and detent 8 is hinged on foot wheel carrier 1.Power ratchet 7 is provided with the return spring 9 that the other end is connected with pedal 3, detent 8 is provided with the tension spring 10 that the other end is connected with foot wheel carrier 1.
During brake, stepping on pedal 3, power ratchet 7 moves down therewith, promotes ratchet 5 to turn clockwise, and when power ratchet 7 engages with ratchet 5 gear teeth, the salient angle compressing brake block 4 of cam 6 contacts wheel 2 to maximum limit position, and braking state is formed.Now, detent 8 also engages with ratchet 5 gear teeth, makes braking state lock, and pedal 3 is self-return under the effect of return shell fragment 12, is continuously stepping on pedal when being prevented effectively from brake.When needing to release brake, again stepping on pedal 3, power ratchet 7 and detent 8 all orders are engaged on the next gear teeth of ratchet 5, and now, cam 6 straight flange contacts with brake block 4, and brake block 4, under the effect of resilience sheet 11, leaves wheel 2, and brake releases.
