Description
Technical field
The present invention relates to castor technical fields, refer in particular to a kind of with the castor for adjusting supporting role.
Background technique
Existing its idler wheel of the castor with support function and support leg are typically all to be separately positioned on castor company in the market
Connect the axis two sides of bracket vertical direction, such idler wheel and support leg be just all with castor connecting bracket eccentric setting, due to rolling
Wheel and support leg are single use that (i.e. castor is in vacant state, support in use, support leg does not use in use
Foot is not in use, castor uses, in vacant state), idler wheel and support leg setting are required to occupy the regular hour, so that rolling
The position that the position and support leg that wheel is rotatablely connected with castor connecting bracket are connect with castor connecting bracket is required to deviation foot
The biggish distance of the axis of wheeling supporting frame vertical direction, this requires that castor connecting bracket has very big load bearing stength, it is no
Then castor is easily damaged due to excess load.
Summary of the invention
In view of the above problems, the present invention provides a kind of castors with adjusting supporting role, by screwing inner ring upwards,
The lower end of inner ring is set to be higher than the lower end of idler wheel, such idler wheel just can freely roll on ground, and main body to be moved just can be by idler wheel
It moves freely, after main body to be moved is moved to scheduled placement position, screwing inner ring downwards connects the lower end of inner ring with ground
It touches and jacks up idler wheel upwards, can thus play the role of support main body to be moved, thus the mobile main body sliding of anti-stop-band, from
And realize the support regulating effect of castor, while idler wheel is also effectively reduced because of prolonged load-bearing by the support load-bearing of inner ring
Caused by damage.
To achieve the goals above, the technical solution adopted by the present invention is as follows：
A kind of castor with adjusting supporting role, including bottom plate, outer ring, inner ring, idler wheel and connecting bracket, outer ring
Top is fixed on bottom plate, and bottom and the inner ring screw thread of outer ring are screwed on, and is positioned on bottom plate at the top of connecting bracket, connecting bracket
Bottom be connected to idler wheel, the distance of idler wheel lower end is arrived in the upper end that the height of inner ring is less than outer ring, and the height of inner ring is greater than outer ring
Lower end to idler wheel lower end distance, inner ring can from its lower end lower than idler wheel lower end position screw to the lower end of inner ring be higher than rolling
Take turns the position of lower end.
Furthermore, the inner wall of the outer ring is equipped with internal screw thread, and the outer wall of inner ring, which is equipped with, matches spiral shell with internal screw thread
Revolve the external screw thread of connection.
Furthermore, the connecting bracket is arranged using inverted U-shaped structure, and the top of connecting bracket can by center rivet
Rotation is connected on bottom plate, and idler wheel is positioned in the U-type groove of connecting bracket bottom by pin shaft.
