Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described.
As it is shown in figure 1, a kind of castor that manual friction stopping device is set, including wheel carrier 1, revolver body 21, right wheel body 22
With axis body 3, wheel carrier 1 having axis hole 4, connects seat 5 and be positioned at the circular arc friction plate 9 of wheel carrier both sides, left and right wheel body 21,22 wraps
Include bearing 23 and wheel rim 24, axis body 3 hollow, the two ends of axis body 3 bearing 23 with left and right wheel body 21,22 respectively coordinate and with wheel
Rim is rotatably assorted；
There is guiding draw-in groove at the two ends of axis body 3, and the centre bore of described wheel rim 24 has guide rail 241, guide rail 241 and guiding inlay card
Close.
Axis hole 4 on described wheel carrier 1 includes arc sections 41, middle square department 42 and lower circular arc portion 43；Described upper circular arc
The diameter line in portion is perpendicular to the top of horizontal plane the containing cavity 411 of under shed；A stop bit is led in the bottom in lower circular arc portion 43
Groove 6；
Described axis body 3 includes Arc Axial body 31, middle square shaft body 32 and lower circular arc axis body with the fixed part of wheel carrier 1
Portion 33, the diameter line of upper Arc Axial body 31 is perpendicular to the top of horizontal plane counterbore 311；
Upper Arc Axial body 31 and lower Arc Axial body 33 coordinate with upper arc sections 41 and lower circular arc portion 43 respectively, middle side
Oblique crank Z body 32 and middle square department 42 are slidably matched and prevent axis body from rotating,
Also include a compression spring 7 and slip locating piece 8,
Compression spring 7 lower end embeds in counterbore 311, upper end is positioned at containing cavity 411, slip locating piece 8 with lead a stop bit
Groove 6 is slidably matched and coordinates with the lower Arc Axial body 33 of axis body 3.Wheel rim 24 coordinates with circular arc friction plate 9.
Guiding position-arresting hole 61 through described wheel carrier 1 is arranged at the bottom of described guiding position-arresting groove 6；
Described slip locating piece 8 includes supporting part 81, seat board portion 82 and manual guiding position-stopping plate 83,
Supporting part 81 coordinates with the lower Arc Axial body 33 of described axis body 3, and seat board portion 82 joins with guiding position-arresting groove 6 slip
Closing, manual guiding position-stopping plate 83 is slidably matched and stop bit with guiding position-arresting hole 61.
As it is shown in figure 1, the supporting part 81 of slip locating piece 8 supports the lower Arc Axial body 33 of axis body 3, now, upper circular arc
