Specific embodiment
Specific embodiment of the present utility model is described below in conjunction with accompanying drawing.
Castor shift position control mechanism of the present utility model, with plastic cement as main material, is used using the ultimate principle of lever
On the pedal 1 of the castor by made by plastic material, coordinate in the presence of positioning component and realize castor straight line moving, universal row
Walk and full brake stops third gear function.Specifically, as shown in Figures 1 to 4, castor shift position control mechanism of the present utility model, bag
Include and cooperate to control the gear adjusting part and positioning component of castor motion, wherein, the gear adjusting part is arranged on
On the pedal 1 of castor, the pedal is being sequentially formed with three gear adjustment portions, including control at the position of castor cross bar axle
It is complete that the universal shelves adjustment portion 12 and control castor that the straight trip shelves adjustment portion 11 of castor straight trip processed, control castor are freely exercised is rotated
Stop grade adjustment portion 13, grade adjustment portion 13 is stopped entirely and the universal shelves adjustment portion 12 is formed as to recessed recessed as shown in Fig. 2 described
Shape, the straight trip shelves adjustment portion 11 is formed as convex convex, and grade adjustment portion 13 of stopping entirely is positioned vertically higher than
The straight trip shelves adjustment portion 11.
The positioning component is arranged on castor, including brake slide block 2, brake pin 3 and flexible member, the brake slide block
2 are provided with and straight trip shelves adjustment portion, the universal shelves adjustment portion and stop entirely grade adjustment portion difference corresponding platform 22 and a groove 21,
And be provided with the pin-and-hole 23 of the placement brake pin and place the placement section 24 of the flexible member.As shown in figure 1, the elasticity
Element may include the first flexible member 4 and the second flexible member 5, and first flexible member 4 is set on the brake pin 3,
Second flexible member 5 is arranged on the placement section 24 and is limited by the placement section 24.
The operation principle of castor shift position control mechanism of the present utility model is introduced below with reference to Fig. 5 to Fig. 7.
<Straight trip gear control>
As shown in figure 5, pedal foot-operated face 14 is upwardly away from into ground is allocated to peak, shelves adjustment portion 11 of now keeping straight on is being stepped on
Enter under the drive of the rotation of plate in the groove 21 of position brake slide block 2, in the pressure straight down for mainly being applied by the second flexible member 5
In the presence of power, pedal 1 is maintained static, in the blind hole 61 that the pin 3 that brakes enters a mainshaft cap 6 in the presence of the first flexible member 4,
The related main shaft of mainshaft cap is no longer turned to, realize that castor orients straight trip function.
<Universal gear control>
As shown in fig. 6, when pushes pedals face 14, pedal 1 is rotated clockwise, the adjustment portion of the lower section of slide block 2 of braking
Universal shelves adjustment portion 12 is switched to by straight trip shelves adjustment portion 11, universal shelves adjustment portion 12 is fitted with corresponding platform 22, because universal
Shelves adjustment portion 12 and straight trip shelves adjustment portion 11 have certain drop, the related brake pin 3 of brake slide block 2 can together it is relative fall, make to stop
Car pin 3 disengages mainshaft cap position, and castor universal walking function is realized in the rotation that affranchises of the related main shaft of mainshaft cap 6.
<Stop full gear control>
As shown in fig. 7, continuing pushes pedals face 14, pedal is rotated clockwise, and the brake lower section adjustment portion of slide block 2 is by ten thousand
Switch to grade adjustment portion 13 of stopping entirely to shelves adjustment portion 12, rotation enters the groove 21 of position brake slide block 2 up to grade adjustment portion 13 of stopping entirely, steps on
Plate stops operating, and because the height of the in the vertical direction of grade adjustment portion 13 of stopping entirely is higher than straight trip shelves adjustment portion 11, therefore brake slide block 2 connects
Strap brake pin 3 is together relative to be risen, and in the blind hole 61 for now entering a mainshaft cap 6 in the presence of flexible member 4 except brake pin, is made
Outside the related main shaft of mainshaft cap is no longer turned to, the brake tooth 25 of the slide block 2 that brakes also is engaged with wheel piece internal tooth, wheel piece is turned
It is dynamic, realize that castor is stopped a grade function entirely.
When needing to carry out un-brake to castor, only need to apply external force, make pedal rotate counterclockwise, allow stop entirely grade adjustment portion 13
Depart from the groove 21 of brake slide block 2, under the elastic force effect of flexible member 4 and flexible member 5, pedal returns to universal gear i.e.
Complete un-brake action.
