Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, below will, by specific embodiment and relevant drawings, the utility model be described in further detail.
As shown in Fig. 1 ~ 8, in one, control single-wheel castor, comprise Connection Block 1, the below of described Connection Block 1 is provided with Connection Block 1 and rotates the castor 2 coordinating, the top of described Connection Block 1 is provided with the axis body 3 that inserts Connection Block 1 upper shaft hole 11 and coordinate with its rotation, controls single-wheel castor and be connected with mobile device by axis body 3 in this.
In described Connection Block 1, be provided with the die cavity 12 that is positioned at described axis hole 11 belows and can holds castor 2, described axis body 3 inside are provided with Extendible knockout pin 31, described push rod 31 is synchronizeed rotation with described axis body 3, can not relatively rotate, described push rod 31 perimembranous are provided with protruding pin 311, and described protruding pin 311 is absorbed in the draw-in groove 35 that is positioned at axis body 3 perimembranous and synchronizes rotation with axis body 3 to realize push rod 31; Described push rod 31 lower ends are stretched out described axis body 3 lower ends and are extended after descending in order to push rod 31 in described die cavity 12 and push down castor 2 peripheral parts to stop its rotation.
In the present embodiment, in described axis body 3, be provided with the runner 32 that is positioned at described push rod 31 tops, described runner 32 outer rims keep being close to docking with push rod 31 upper ends, described runner 32 outer rims are provided with groove A(321), groove B(322) and flange part 323, the centre of runner 32 offers inner hexagonal hole, can be by changing the axial location that contacts outer rim and change gained push rod 31 of runner 32 and push rod 31 upper ends during with hex spanner rotating wheel 32, control push rod 31 up, descending and midway location, described groove A(321) radial depth be greater than described groove B(322) radial depth, in the time that push rod 31 upper ends contact with groove B, push rod mediates, in the time contacting with groove A, push rod 31 is up, while contact with flange part 323, push rod 31 is descending.
In the present embodiment, described push rod 31 belows are fixed with rotating disk 33, described die cavity 12 upper surfaces are provided with the deep gouge 121 that is positioned at rotating disk 33 tops, and described rotating disk 33 upper surfaces are evenly equipped with double wedge 331 along perimembranous and embed in described deep gouge 121 and rotate to limit described axis body 3 in order to the up rear double wedge 331 of push rod 31; Described rotating disk 33 lower surfaces are evenly equipped with groove 332, be provided with the claw 13 that is positioned at described rotating disk 33 belows and insert described groove 332 in order to the descending rear described claw 13 of push rod 31 and rotate rotating disk 33 outer rims simultaneously with restriction axis body 3 and push down described castor 2 to stop its rotation in described die cavity 12.
In the present embodiment, be provided with the spring 34 that is sheathed on described push rod 31 peripheries to drive push rod 31 upper ends to be close to described runner 32 outer rims all the time in described axis body 3, described axis body 3 is rotaryed connection with described Connection Block 1 by the bearing 14 of being located in described axis hole 11.
The working process of controlling single-wheel castor in the utility model is:
