Technical scheme is used by the utility model overcomes its technical problem：
A kind of medical equipment direct current generator around set detecting device, including：The closed housing of surrounding, it is arranged at housing rear end
The support I that be open, is vertically arranged in housing, the rotating shaft being installed in support I horizontally rotated by bearing I, is arranged at housing
The magnetic powder brake of front end, the gear I being installed on magnetic powder brake output shaft, itself and the phase of gear I for being installed on rotating shaft front end
Meshed gears II, the guide rail for being horizontally placed on housing bottom and being located between support I and opening, it is slidably mounted on guide rail
Slide plate, the direct current generator being installed on slide plate, the gear IV being fixed on by holding screw in direct current generator output shaft, vertical peace
The gear III for being rotatablely installed in support II loaded on the support II on slide plate and by bearing II and being meshed with gear IV, turn
The rear end of axle is coaxially arranged with splined shaft, and gear III is slided and is plugged on splined shaft, when slide plate slides to rearmost end, direct current
Machine stretches out from opening.
In order to realize more preferable closure, further also include the cylinder being vertically arranged on housing, the piston of cylinder
Bar is connected with hatch door, and when the piston rod of cylinder all stretches out, hatch door is by closure of openings.
The beneficial effects of the utility model are：Before experiment starts, slide plate is outwards extracted out from opening, it is convenient that direct current is installed
Motor, after direct current generator is fixed, gear IV is set on the output shaft of direct current generator, and is fixed by holding screw.Afterwards
Slide plate is inwardly promoted whole direct current generator be located in housing, because support II follows slide plate to move, therefore gear III is along spline
Axle slides, and during experiment, DC motor Driver gear IV rotates, and gear IV passes through gear III and drives splined shaft to rotate, and splined shaft drives
Moving gear II rotates, and gear II drives magnetic powder brake to rotate by gear I, i.e. adjustable by the electric current for adjusting magnetic powder brake
The reaction torque of whole magnetic powder brake, so as to simulate real load.Carried out when being tested due to direct current generator in the housing of closing, from
And disturbed less by external environment condition, the precision of experimental data collection is improved, while its experiment process operation is simple and convenient, improves
Conventional efficient.
