Abstract
The utility model discloses its drip irrigation device of a kind of castor is comprise runner and wheel carrier, described runner comprises the first runner and the second runner, described wheel carrier comprises wheel shaft and the adapter shaft for being connected with chair, it is the vertical switching mechanism that vertical direction overturns that described wheel shaft and the second runner are provided with for runner and wheel shaft being overturn from horizontal direction, the castor that the utility model is more stable after aiming to provide a kind of stopping.
Description
Technical field
The utility model relates to a kind of castor.
Background technology
Castor is a general designation, comprises movable castor and rigid castors.Movable castor is also with regard to our said cardan wheel, and its structure allows 360 degree of rotations; Rigid castors is also direction-caster, and it does not have rotational structure, can not rotate.Along with the rise of the industrial revolution, increasing equipment needs mobile, and castor is also just more and more extensive in whole world application, and all trades and professions almost be unable to do without castor.Arrived the modern development along with science and technology, equipment is more and more function and high usage also, and castor has just become indispensable parts.The development of castor is also just more specialized and become a special industry.
At present, the castor on market, it comprises runner, wheel carrier and brake, and brake is installed on runner circumference place, and runner is stopped the rotation.Although this castor can make, castor is out of service makes chair fix, and the area of contact on castor and ground after brake is little, causes chair to remain unchanged after castor brake very unstable, easily slippage occurs.
Utility model content
For the deficiency that prior art exists, the castor that the purpose of this utility model is more stable after being to provide a kind of stopping.
For achieving the above object, the utility model provides following technical scheme: a kind of castor, comprise runner and wheel carrier, it is characterized in that: described runner comprises the first runner and the second runner, described wheel carrier comprises wheel shaft and the adapter shaft for being connected with chair, and it is the vertical switching mechanism that vertical direction overturns that described wheel shaft and the second runner are provided with for runner and wheel shaft being overturn from horizontal direction.
By adopting technique scheme, runner can be made to overturn vertically by vertical switching mechanism, making runner side ground proximity thus the area of contact that actv. increases runner and ground reduces the generation of sliding phenomenon.
The utility model is set to further: described vertical switching mechanism comprises the slot to make way matched with described adapter shaft and the groove be opened in the middle part of described wheel shaft, described slot to make way comprises the first slot to make way and radial the second slot to make way being arranged at the second runner that arrange along axle axial, described first slot to make way one end communication groove, the other end is communicated with the end face that wheel shaft extends to the second runner, described adapter shaft is articulated with in groove, and described groove is provided with locating dowel pin near slot to make way side.
By adopting technique scheme, user, by taking out locating dowel pin, makes slot to make way and the matching of wheel carrier phase to overturn wheel, makes wheel become horizontally set.
The utility model is set to further: described groove is ball recess, and described adapter shaft is connected with the ball that is embedded at described ball recess and described ball can rotate freely in ball recess.
By adopting technique scheme, the utility model castor can be allowed to be 360 degree and to rotate freely, thus becoming universal caster wheel.
The utility model is set to further: described second slot to make way is provided with chute along the second runner circumference, is embedded with the slide block coordinated with chute in chute, and described cunning described slide block end face matches with adapter shaft with the circumferential cooperation of described second runner.
By adopting technique scheme, castor can be made can not to cause because of slot to make way in operational process stuck, and can adapter shaft be blocked when the vertical state of runner, make adapter shaft keep stable, there will not be overturning phenomenon.
The utility model is set to further: be provided with Compress Spring between described slide block and described chute, and described slide block is provided with the control stalk for stirring slide block.
By adopting technique scheme, slide block is made in motion process in chute, to cause slide block to slip into chute and then runner causes stuck because of slot to make way by relative sliding.
The utility model is set to further: described first runner lateral surface is provided with friction pad.
By adopting technique scheme, the more stable sliding phenomenon that reduces further of castor in vertical process is produced.

Detailed description of the invention
Referring to figs. 1 through Fig. 8, the utility model castor embodiment is described further.
A kind of castor, comprise runner and wheel carrier, it is characterized in that: described runner comprises the first runner and the second runner, described wheel carrier comprises wheel shaft and the adapter shaft for being connected with chair, and it is the vertical switching mechanism that vertical direction overturns that described wheel shaft and the second runner are provided with for runner and wheel shaft being overturn from horizontal direction.
By adopting technique scheme, runner can be made to overturn vertically by vertical switching mechanism, making runner side ground proximity thus the area of contact that actv. increases runner and ground reduces the generation of sliding phenomenon.
Described vertical switching mechanism comprises the slot to make way matched with described adapter shaft and the groove be opened in the middle part of described wheel shaft, described slot to make way comprises the first slot to make way and radial the second slot to make way being arranged at the second runner that arrange along axle axial, described first slot to make way one end communication groove, the other end is communicated with the end face that wheel shaft extends to the second runner, described adapter shaft is articulated with in groove, and described groove is provided with locating dowel pin near slot to make way side.
By adopting technique scheme, user, by taking out locating dowel pin, makes slot to make way and the matching of wheel carrier phase to overturn wheel, makes wheel become horizontally set.
Described groove is ball recess, and described adapter shaft is connected with the ball that is embedded at described ball recess and described ball can rotate freely in ball recess.
By adopting technique scheme, the utility model castor can be allowed to be 360 degree and to rotate freely, thus becoming universal caster wheel.
