The movement of the spherical wheel can be accurately positioned, and the problems that the moving direction of the conventional medical equipment is easy to deviate and the accurate positioning cannot be realized during steering can be solved; the spherical wheel of the invention is started quickly, and can solve the problem that the existing medical equipment can not move freely when moving; the ball wheel of the invention can not stop when moving forward, thus solving the problem that the prior medical equipment is easy to stop when moving and can be moved by pushing the handle by a user.
Description
Technical field
The present invention relates to a kind of spherical take turns, particularly relate to one and need not to turn in advance, can accurately determine when turning to
The spherical of position is taken turns and uses this spherical equipment taken turns.
Background technology
Existing armarium has the polytype such as car-type, portable, hand-held, and wherein car-type can move
Dynamic armarium is made up of main frame main body, keyboard, display, castor, handle etc..Car-type is removable to be set
Having four castors, each castor is individually fixed on below main frame main body, supports whole armarium, foot
Wheel is to use eccentric manner to install, and i.e. the most on one wire, handle is also integrally fixed at for the center of castor and rotating shaft
On apparatus subject.User's driving handle, Mobile medical just can move, but the premise of movement is foot
Wheel needs to turn in advance, i.e. the center of castor is turning initially to the rightabout of moving direction, say, that first
First there are the process that a castor rotates, radius of turn and the size of castor and rotating shaft installation position around rotating shaft
It is equipped with pass, such as the A size of Fig. 1.If A size is the least, easily cause turning ineffective, move and have some setbacks,
Even pause motionless, just can move after needing user's adjustment direction again.If A size is too big, then can
The pre-turning radius of castor before causing instrument to move is too big, causes instrument to first have to a skew,
The direction that operator needs can be redirect to, be i.e. difficult to the direction motion needed according to operator, and because of partially
The existence of concentric mechanism, can cause instrument unstable when turning to too fast.User pushes or pull on handle, and castor needs
Just can towards the side that user guides forward or backward after turning in advance.
Summary of the invention
In order to solve above-mentioned technical problem, the present invention provides one to need not in advance to turn to, can be accurately when turning to
This spherical armarium taken turns is taken turns and used to the spherical of location, its simple in construction, easy to use.
Technical scheme is as follows:
One is spherical takes turns, and described spherical wheel includes spherical wheel body, fixing lower cover and fixed pedestal；Described solid
