By adopting the above-described technical solution, the beneficial effects of the invention are as follows：
Night vision device is accommodated into containing cavities, in use, using hand by the present invention by the way that containing cavities are arranged at the top of the helmet usually
The convex block for holding night vision device cover top portion pulls out containing cavities down.The present invention can be achieved the quick storage of night vision device and beat
It opens, it is convenient and practical, and the height of interpupillary distance and lens barrel can be finely adjusted.
When needing using night vision device, the past drop-down of convex block of night vision device cover top portion is grasped, during pulling,
Night vision device shell drives connect band to extend, and connect band drives the rotation of the first support shaft, the first support shaft band during extension
Dynamic clockwork spring stores power, while during the first support shaft rotates, ratchet wheel, when night vision device moves to suitable position
When, it stopping drag, pawl blocks ratchet, to which the first support shaft be fixed, night vision device stop motion.
When night vision device is using terminating to need to take in containing cavities, button is pressed with hand, button pushes pushrod movement, push rod to exist
In motion process, the 6th gear of rack drives of end rotates, and the 6th gear drives column rotation, column that the 7th gear is driven to turn
Dynamic, the 7th gear drives eighth gear rotation, while eighth gear rotates, the second connecting rod is driven to move downward, and second connects
Extension bar band pawl is rotated down around the 5th support shaft, to make pawl be detached from ratchet, when ratchet loses the limitation of pawl
Afterwards, the first support shaft reversely rotates under the elastic force effect of clockwork spring, connect band is wrapped in the first support shaft, connect band
It drives night vision device to be moved toward containing cavities again, realizes the automatic accomodation of night vision device.After night vision device takes in containing cavities completely, stop pressing
Button is pressed, button moves out under the elastic force effect of resetting spring, and the 6th gear of rack drives on push rod rotates backward, after
And drive the 7th gear rotate backward, the 7th gear drive eighth gear rotate backward, eighth gear drive the second connecting rod to
Upper movement, the second connecting rod band pawl rotate up around the 5th support shaft, and pawl and ratchet engage again.
It, can be according to need during pulling out night vision device as a result of the limit method of pawl and ratchet
The height for adjusting night vision device stops drag after night vision device is drawn to proper height, and due to the limitation of pawl, ratchet is not
It can be rotated backward under the elastic force effect of clockwork spring, the length of night vision device pulling then can be flexibly controlled, so that night vision device
It is more corresponding with the height of eyes.When night vision device during use, find display screen and the height of eyes not to it is corresponding when
It can be finely adjusted.When display screen is higher relative to eyes, convex block can be pulled with hand again, to reduce the height of display screen；When
When display screen is relatively low relative to eyes, button can be pressed lightly on hand, allow the first support shaft under the elastic force effect of clockwork spring
It reversely rotates, the height of display screen will be improved.
When needing to be adjusted interpupillary distance, the first knob is rotated by hand, the first knob drives third tooth by connecting rod
Wheel rotation, third gear drive first gear rotation, first gear that the rotation of the first screw rod, the first screw rod is driven to drive the first support
Plate is moved left and right along the first screw rod；Third gear drives the rotation of the 4th gear, the 4th gear to drive the rotation of the 5th gear simultaneously,
5th gear drive second gear rotation, second gear drive the second screw rod rotation, the second screw rod drive the second support plate along
Second screw rod moves left and right, and the moving direction of the first support plate and the second support plate is on the contrary, with the first support plate and second
The movement of support plate, drive the first lens barrel and the second lens barrel to the left and to the right, realize the adjustment to interpupillary distance.
When needing to adjust the height of lens barrel, the second knob is rotated by hand, the second knob drives the rotation of third screw rod, third
Screw rod moves up and down while rotation along nut, and to drive third support plate to move up and down, third support plate drives the
One lens barrel and the second lens barrel move up and down, and realize the adjustment of lens barrel height.
