It crosses brake block to fix castor, the total quality of product is restrict, while in the case where using Uneven road steady, such as castor
It highly cannot be adjusted, that stability and horizontality that will also influence its product.At present, the use of state of China castor is more universal, but
It is that quality is irregular, the castor that there are problems that certain mass influences the use of product.Important zero as removable product
One of part, the quality of castor directly affect the safe to use and service life of product, and to improve castor quality, one kind must be designed by having
Reliable in quality, long-lived castor.
Invention content
The purpose of this utility model is that and provides a kind of durable castor, easy to operate, durable with supporting
The advantages that.
To achieve the above object, a kind of durable castor of the utility model, including：Pedestal；Link, the link can
It is pivotally connected to the lower section of the pedestal；Wheel body, the wheel body are rotatably connected on by wheel shaft on the link；Brake
Plate, installing plate and connecting rod, the braking vane are rotatably connected to by connecting shaft on the link, and the installing plate can
It is pivotally connected on link, the connecting rod is connected between braking vane and installing plate；Jam plate, the jam plate is rotatably
It is connected on braking vane.
Further, support base and a pair of of elastomer are further included, the support base is installed on a mounting board, the elastomer
One end be connected in connecting shaft, the other end connect on a mounting board.
Further, the support base is installed on a mounting board by lead screw, and the support base can pass through lead screw
Height adjusting is carried out, to adapt to a variety of different surface states.
Further, the installing plate is rotatably connected to by wheel shaft on link, one end of the connecting rod
One end of braking vane is connected to by the second connecting shaft, the other end of the connecting rod is connected to installing plate by third connecting shaft
One end.
Further, the braking vane drive installation plate makes support base that can move up and down, after support base moves up, castor
With motion state, after support base moves down, castor has stationary state.
Further, the braking vane driving jam plate rotation, after braking vane moves down, jam plate, which locks wheel body, to be made at castor
In lockup state, after braking vane moves up, jam plate, which unclamps wheel body, makes castor be in movable state.
The utility model has the advantages that：When castor needs mobile, by applying upward power to braking vane, make braking vane
It is rotated around connecting shaft, so as to drive connecting rod that installing plate is made to be rotated up around wheel shaft, support base is driven to move up, make support base bottom surface
Higher than the bottom end of wheel body, thus wheel body contacts ground, while jam plate rotates around the second connecting shaft and unclamps wheel body, unlocks wheel body,
Wheel body can be rolled freely, and castor is i.e. removable, downward by applying to braking vane when castor is moved to a certain designated position
Power, make braking vane around connecting shaft rotate, so as to drive connecting rod that installing plate is made to be rotated down around wheel shaft, drive under support base
It moves, support base bottom surface is made to be less than the bottom end of wheel body, thus wheel body leaves ground, support base contact ground, while jam plate is around second
Connecting shaft rotation lock wheel body, make wheel body steadily, reliably stand on ground, in addition the utility model support brake operation letter
It is single, it as long as foot is stepped on, can brake, make castor stabilization motionless in designated position, be commonly used, wheel body abrasion is small, prolonged resistance to
With can quickly realize support and movement, reduce the operating time.
Description of the drawings
The utility model is described further below in conjunction with the accompanying drawings：
Fig. 1 is utility model diagram；
Wherein：1 be pedestal, 2 be link, 3 be wheel body, 4 be wheel shaft, 5 be connecting shaft, 6 be braking vane, 7 be connecting rod,
8 it is installing plate, 9 be jam plate, 10 be elastomer, 11 be support base, 12 be the second connecting shaft, 13 is third connecting shaft.
Specific embodiment
