Description
Technical field
The invention belongs to castor technical fields, are related to a kind of castor and infusion support and its application method with the castor.
Background technique
Traditional infusion frame mostly uses greatly bottom belt to have the pedestal of star base, although rigid castors on star base, and existing
With the castor of strap brake function in technology, but traditional castor still remains following problems:
1, the brake of each castor is independent control structure, and needing patient successively to operate the brakes of all castors just can be into
Row braking；
2, existing castor generally uses rubber parts increasing friction force mode to brake, and not only can may also lack after brake
Amount movement, can not stablize brake, while will affect brake function after rubber parts aging；
3, the existing rubber parts that castor brakes generally is stepped on part with foot and is connect, and foot steps on part and is generally connected to idler wheel one
Side, since idler wheel can rotate, it is therefore desirable to which rotation roller respectively makes foot step on part and be located at outside just and can step on foot and steps on part and stop
Vehicle, it is cumbersome.
Summary of the invention
