A kind of adjustable medical stage apparatus of pitch velocity and its method of adjustment
Technical field
The present invention relates to medical machinery field, the adjustable medical stage apparatus of especially a kind of pitch velocity and its adjustment side
Method.
Background technology
In the medical field, a variety of medical carrying platforms are often used, such as operation workbench, instrument inspection are used and put down
Platform, outpatient service or patient's bed in hospital etc..In many situations, these carrying platform required angles are adjustable, to comply at any time
Medical treatment detection or the requirement of operation.
In most circumstances, it may be necessary to be adjusted according to the waist bending degree of patient before and after platform to angle.
But under some special cases, it is also necessary to adjust the lateral tilt angle of entire carrying platform.I.e. so that carrying platform direction
Side tilts.Some existing adjustment means, which are difficult to meet, simply and reliably reaches this angle adjustment requirement.Moreover, because
The adjustment gearing component needed is accurate reliable, and under daily non-adjustment state, it is difficult to during use to these essences
Close transmission parts interfere and influence its machine driving precision.
