Position or suitable position, may result in external trachea, electric wire or other connectors and are torn, accidents caused, although market
On occurred in that the castor that can be braked, but under strong vibration, braking effect gradually can be released from, and do not reach and make completely
Dynamic effect.
The content of the invention
It is an object of the invention to provide it is a kind of still can brake completely under lasting judder with self-locking mechanism
Castor.
The object of the present invention is achieved like this：Castor with self-locking mechanism, including roller and be hinged with roller centre bore
And the support bar that back-up roller wheel is rotated around it, roller be located at support bar two ends, wherein, if being provided with the wheel disc of the roller
Dry through hole, is provided with locking device on the support bar, lock device, institute are provided between the locking device and the roller
State lock device to be connected with the roller by the through hole；The locking device concrete structure is：It is fixed on the support bar
Fixed arm is provided with, cursor on the fixed arm, is hinged with, described cursor one end is provided with backing pin；The lock device tool
Body structure is：Be provided with some cuttings being engaged with the through hole on its end face, cutting insertion through hole can make lock device with
Roller synchronous axial system, is provided with fluting on the end face corresponding with the cutting, rotary motion arm makes the backing pin open with described
Slot lock is closed prevents roller from rotating.
Castor with self-locking mechanism mentioned above, wherein, the other end of the cursor is provided with plectrum, by plectrum
Conveniently adjusted cursor.
Castor with self-locking mechanism mentioned above, wherein, the lock device is discoid, is set in the support bar
On, the cutting and fluting are evenly distributed on the lock device.
Castor with self-locking mechanism mentioned above, wherein, the end face of the vertical lock device of the cutting can be quick
Cutting is inserted in the through hole of roller, it is easy for removal and installation.
Castor with self-locking mechanism mentioned above, wherein, latch, the roller position have been radially arranged on the support bar
Between the latch and locking device, simple structure can prevent roller from coming off from support bar.
Castor with self-locking mechanism mentioned above, wherein, pad is arranged with the support bar, the pad is located at institute
State between latch and roller, in sliding process, it is to avoid friction between roller and the latch, make slip more smooth.
The present invention is prominent and beneficial compared to existing technology to be had the technical effect that：Simple structure, easy to make, low cost, and
And it is easy for removal and installation, be conducive to maintenance, even if in strong vibration is continued, backing pin is sealed also very firm with fluting
Gu, prevent roller from rotating, position skew occurs under itself vibration so as to prevent equipment, causes joint outer part to be torn, or
The generation of other accidents, improves safety.
