Background technology
In the classroom of many schools, all dispose video showing platform and monitoring camera, video showing platform and monitoring camera are independent separately mostly to be provided with, increased overlapping investment, caused the waste of fund, at present, video showing platform on the market takes up space in order to reduce in design, in time spent not, the camera lens sway brace is folded, open it in use, then height of camera lens etc. is regulated, use cumbersome, though the video showing platform lens arm can fold, but show stand panel area is big and can't change the lectern area that has accounted for only about half of when placing on lectern, teacher's textbook of last class hour, teaching notes, placement space on lectern such as teaching materials is very narrow, and video showing platform places dangerously on lectern, and teachers and students fell the video showing platform touching easily near dais when walking.
Summary of the invention
The technical problem to be solved in the present invention is at above problem, provide a kind of can make camera video display and the monitoring between the conversion, camera is easy to adjust, range of adjustment is big, little conversion equipment takes up space.
For addressing the above problem, the present invention adopts following technical scheme: a kind of conversion equipment that makes camera conversion between video display and monitoring, this conversion equipment comprises guide rail, described guide rail is provided with jacking gear, jacking gear comprises motor of fixedlying connected with guide rail and the elevator that slides along guide rail, and described drive of motor is connected with screw rod, and described screw rod is threaded with elevator, described elevator is fixedly connected with linking arm, and described linking arm is provided with camera.
A kind of concrete prioritization scheme, described guide rail is provided with groove, and described elevator is provided with the orienting lug that matches with groove.
A kind of concrete prioritization scheme, described guide rail lower hinge has display platform.
A kind of concrete prioritization scheme, described guide rail be provided with stop, described stop is electrically connected with motor.
A kind of concrete prioritization scheme, described guide rail bottom is provided with the travel switch that is used for controlling motor positive and inverse.
Beneficial effect: the present invention adopts technique scheme, have the following advantages: because camera links to each other with elevator, can regulate the height of camera by the lifting of elevator, when camera drops to close together with display platform, become the imaging camera of video showing platform, when camera is elevated to the guide rail top, become monitoring camera, make a camera can be applied to imaging and monitoring, reduced overlapping investment, improved the utilization factor of camera, because display platform is articulated in the bottom of guide rail, in use display platform is opened again, made display platform be in horizontality, after using, display platform is folding downwards, make display platform be in plumbness, and whole conversion equipment is fixed on the wall, so saved the space, improved safety in utilization.
Below in conjunction with drawings and Examples the present invention is elaborated.
