Description
Technical field
The utility model relates to a kind of medical equipment adjusting device, particularly a kind of LED shadowless lamp motorized adjustment hot spot device.
Background technology
It is all generally adopt manual adjustments that existing shadowless lamp hot spot regulates, manual adjustments shadowless lamp hot spot rotates dumb, need during adjustment repeatedly repeatedly to rotate the hot spot effect wanting when just can reach operation to reach, very large inconvenience is brought to actual operation, and the requirement on machining accuracy of the device of this manual adjustments hot spot parts in actual production processing is very high, working (machining) efficiency is lower.
Summary of the invention
The purpose of this utility model is to overcome above deficiency, provides a kind of structure simple, uses conveniently LED shadowless lamp motorized adjustment hot spot device.
The purpose of this utility model is achieved through the following technical solutions: a kind of LED shadowless lamp motorized adjustment hot spot device, comprise interior platen and external pressure plate, external pressure plate is connected with light modulation seat, the bottom of light modulation seat is provided with stepper motor, stepper motor is covered with motor fixed cover, the top of light modulation seat is connected with interior platen, interior platen is connected with light modulation dish by guide post, the motor shaft of stepper motor is connected with lifting screw, the top of lifting screw passes light modulation dish, be provided with lifting nut between lifting screw and light modulation dish, in interior platen, be provided with lead limit switch.
The utility model compared with prior art has the following advantages: drive lifting screw to rotate by electric machine rotation, thus drive lifting nut to move axially along guide post, and then lifting nut drives light modulation dish to move up and down, moving up and down of light modulation dish realizes light modulation by the movement of driven by motor lamp panel, structure is simple, use more for convenience, can be very fast realize light modulation.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
Number in the figure: platen, 2-light modulation seat, 3-lifting nut, 4-stepper motor, 5-motor fixed cover, 6-guide post, 7-light modulation dish, 8-motor shaft, 9-lifting screw, 10-lead limit switch, 11-external pressure plate in 1-.
detailed description of the invention:
In order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment, only for explaining the utility model, does not form the restriction to the utility model protection domain.
As Fig. 1 shows the detailed description of the invention of a kind of LED shadowless lamp of the utility model motorized adjustment hot spot device, comprise interior platen 1 and external pressure plate 11, external pressure plate 11 is connected with light modulation seat 2, the bottom of light modulation seat 2 is provided with stepper motor 4, stepper motor 4 is covered with motor fixed cover 5, the top of light modulation seat 2 is connected with interior platen 1, interior platen 1 is connected with light modulation dish 7 by guide post 6, the motor shaft 8 of stepper motor 4 is connected with lifting screw 9, the top of lifting screw 9 passes light modulation dish 7, lifting nut 3 is provided with between lifting screw 9 and light modulation dish 7, lead limit switch 10 is provided with in interior platen 1.
In use, shadowless lamp lamp surface glass is fixed by light modulation seat 2 and interior platen 1, motor fixed cover 5 and stepper motor 4 are fixed on light modulation seat 2 by M3 screw, lifting nut 3 is connected with motor shaft 8, stepper motor 4 rotates and drives lifting screw 9 to rotate, lifting screw 9 drives lifting nut 3(lifting nut and light modulation dish to fix) to move axially thus lifting nut 3 drives light modulation dish 7 to move up and down (moving up and down of light modulation dish realizes light modulation by the movement of driven by motor lamp panel) along guide post 6, motorized adjustment hot spot apparatus structure described in the utility model is simple, use more for convenience, can be very fast realize light modulation.
