It is that bulb has taken place to damage and will light another spare bulb immediately in the operating lamp use that operating lamp switches, and existing operating lamp mostly is to utilize two bulbs that are fixed on diverse location to light realization at diverse location respectively.Aforesaid way can cause moving of hot spot to bring visual influence for the doctor who is undergoing surgery, utility model patent CN03220774.3, the name of innovation and creation is called " surgical operation microscope stand-by lamp apparatus for fast switching ", the quick switching of stand-by lamp is by manual realization in this invention, and the operation assistant goes to standby bulbs of operating lamp by Rotation With Changing lamp knob the position of former operation bulb.The hand rotation bulb is expense not only, and both hands should keep the cleanest in operation, any other touch all cannot, therefore press for a kind of operating lamp that automatic centering is switched.
Summary of the invention
The present invention is directed to the defective in the above-mentioned field, a kind of bulbs of operating lamp automatic centering switching device shifter is provided, the bulb of not only lighting when switching switches, the position of bulb also exchanges simultaneously, make the bulb of light yellow be positioned at center and reliable the maintenance all the time, hot spot is positioned at the center all the time and can does not bring visual influence to avoid the error that produces therefrom to the patient when switching like this, has guaranteed that surgical procedure is more safe and reliable.
Bulbs of operating lamp automatic centering switching device shifter, comprise driven unit, positioning component, Electric Machine Control assembly and lamp socket fixation kit, it is characterized in that: described lamp socket fixation kit comprises reflection shell, fixed cover and the turntable of two groups of bulbs is installed, the axle of described turntable is fixed in the fixed cover of reflection shell eccentric orfice by bearing and axle sleeve, driven unit drives the turntable eccentric rotary and turn-offs by Electric Machine Control assembly controlling and driving assembly, and turntable is fixed by positioning component, the distance of described reflection shell center and eccentric orfice equals the distance at bulb and turntable shaft center.
Described driving mechanism comprises motor, the driving wheel with eccentric elongated slot, little axle and coupking shaft, and described driving wheel is fixed on the motor shaft, and little axle is fixed on the coupking shaft, and described little axle is positioned at the eccentric elongated slot of driving wheel, and described turntable is fixed on the coupking shaft.
Described Electric Machine Control assembly comprises locating piece, the microswitch that is fixed on the fixed cover and is fixed in adjustable touching lever on the turntable, and described microswitch is fixed on the locating piece and has control lever, and control lever touches mutually with adjustable touching lever and realizes that motor turn-offs.
Be fixed with heat insulating mattress on the described locating piece, described microswitch maintenance is on heat insulating mattress.
Described positioning component comprises the location pit of retainer spring, location ball and coupking shaft side, and described retainer spring impels the location ball to withstand the location pit to realize that turntable fixes.
The present invention is by driven unit 180 degree rotations, drive the turntable eccentric rotary, bulb occurrence positions on the turntable is exchanged, cutting off the electricity supply by the Electric Machine Control assembly when being rotated in place stops operating driven unit, positioning component is fixed revolving table position simultaneously, make displacement fixing maintenance after conversion of bulbs of operating lamp, because the spacing at reflection shell center and eccentric orfice center equals the spacing of bulb apart from the turntable shaft center, thereby guarantee to do have a bulb to be positioned at the center of reflection shell all the time in the 180 degree rotations at driven unit.
Motor rotates in the driven unit, rotates thereby drive turntable.
In the rotation process of turntable, adjustable touching lever touches mutually with the control lever of microswitch, sends to put in place to control circuit and turn-offs the signal of motor, and motor stops operating.
When motor stopped operating, coupking shaft stopped operating, and the location ball withstands the coupking shaft side at a distance of the accurate location that the pit of 180 degree is realized 180 degree under the pressure of spring, keep reliably when no switching signal.
Among the present invention, after lamp that monitor is monitoring centre bit is spoilt, then drive motors drives driven unit and does 180 degree rotations, when being rotated in place, the Electric Machine Control assembly closes power machine stops operating motor, positioning component drives ball and withstands the accurate location that the location pit on the coupking shaft is realized turntable simultaneously, thereby the nothing skew that realizes bulb and operating lamp hot spot is switched.
