The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

As shown in fig. 1 to 26, a night vision device bracket includes a latch unit 100 for fixedly mounting on a helmet, an up-down adjusting unit 200 fixed above the latch unit 100, a turn-over unit 300 fixedly connected to a lower end of the up-down adjusting unit 200, a level adjusting unit 400 fixed to the turn-over unit 300, and a lower end of the level adjusting unit 400 fixedly connected to an upper end of a night vision device.

The bolt device 100 comprises a sliding base 101, a limiting space for accommodating a limiting bolt 102 is formed in the front part above the sliding base 101, the limiting space is matched with the limiting bolt 102, and the limiting bolt 102 can move back and forth in the limiting space. Open on the slide base 101 preceding terminal surface of spacing space both sides and have U type groove forward, also open forward U type groove on the preceding terminal surface of spacing spring bolt 102, screens control lever 103 inlays in U type inslot, and the design in U type groove is for holding screens control lever 103, and the both ends of screens control lever 103 are located the outside of slide base 101.

An inclined long circular hole 1031 is formed in the middle of the clamping control rod 103, a first fixing shaft 1011 is located inside the inclined long circular hole 1031, two ends of the first fixing shaft 1011 penetrate through the inclined long circular hole 1031 and then are fixed to the inner walls of the upper portion and the lower portion of the limiting bolt 102, and the first fixing shaft 1011 can slide in the inclined long circular hole 1031. The position-locking control rod 103 on both sides of the inclined oblong hole 1031 is provided with a horizontally extending oblong hole 1032, and the extending directions of the oblong hole 1032 on the left side and the oblong hole 1032 on the right side are respectively the same as the length direction of the position-locking control rod 103. The left long round hole 1032 and the right long round hole 1032 are respectively provided with a control rod sliding shaft 1012, two ends of the control rod sliding shaft 1012 penetrate through the left long round hole 1032 and then are fixed on the upper end face and the lower end face of the left U-shaped groove, and two ends of the control rod sliding shaft 1012 penetrate through the right long round hole 1032 and then are respectively fixed on the upper end face and the lower end face of the left U-shaped groove. The control rod sliding shafts 1012 can slide in the corresponding long circular holes 1032, for convenience of fixation, two ends of the left long circular hole 1032 and the right long circular hole 1032 are respectively provided with a cylindrical hole 1033 used for clamping the control rod sliding shafts 1012, the hole diameter of the cylindrical hole is the same as that of the control rod sliding shafts 1012, and the width of the hole of the long circular hole 1032 is slightly smaller than the diameter of the control rod sliding shafts 1012, so that the control rod sliding shafts 1012 are prevented from sliding.

Because the inclined oblong hole 1031 is inclined, when the clamping control rod 103 moves left and right, the position of the first fixed shaft 1011 in the inclined oblong hole 1031 can be different by pushing the clamping control rod 103 left and right, the inclination angle and the length of the inclined oblong hole 1031 are set according to requirements, the limiting bolt 102 is retracted when the clamping control rod 103 is pushed to one side of the inclined oblong hole 1031, unlocking is achieved, and when the clamping control rod 103 is pushed to the other side of the inclined oblong hole 1031, the limiting bolt 102 extends out, and locking is achieved.

In order to limit the slot unlocking key 408, a limiting slot 4081 is arranged on the lower end face of the slot unlocking key 408, a slot limiting block 410 matched with the limiting slot 4081 is fixed on the upper end face of the slot lower cover 403, and the upper end of the slot limiting block 410 is arranged in an L-shaped structure with a right opening, so that the sliding range of the slot unlocking key 408 is guaranteed, and under the natural state, under the elastic action of a slot unlocking spring 409, the inner wall of the right side of the limiting slot 4081 abuts against the end face of the left side of the slot limiting block 410.

The corresponding card slot lower cover 403 is provided with a through hole corresponding to the dovetail buckle latch 406, and under the action of the latch spring 407, the left side of the dovetail buckle latch 406 passes through the through hole of the card slot lower cover 403 and then protrudes out of the card slot lower cover 403 in a natural state.

The lateral part of the through hole of the lower end face of the slot lower cover 403 is provided with a dovetail groove, the dovetail seat 411 is matched with the dovetail groove of the slot lower cover 403, and the dovetail seat 411 is provided with a clamping hole matched with the dovetail buckle bolt 406.

The utility model discloses a theory of operation:

the length of the limit bolt 102 is adjusted, the bracket is fixed on a helmet through the bolt device 100, the locking and unlocking of the limit bolt 102 can be controlled by shifting the clamping control rod 103 left and right, and the extension length of the limit bolt 102 in the locking state can be adjusted by shifting the clamping adjusting sheet 106 left and right.

The sliding knob 205 is rotated to the unlocking side, at this time, the length direction of the sliding block 2041 is consistent with the length direction of the sliding groove 2011, the rotating base 203 can slide up and down on the cover plate 201 at will, after the cover plate 201 slides to a required position, the sliding knob 205 is rotated to the other side, at this time, the sliding block 2041 is clamped in the sliding groove 2011, and the rotating base 203 and the cover plate 201 are locked and fixed.

When the night vision device is used, the rotating button 302 is pressed, the rotating shaft limiting seat 305 is turned to a required position, and the angle of the night vision device can be finely adjusted by rotating the fine adjustment knob 306.

The slide unlocking key 404 is pressed to slide the night vision device on the double-track rack 401, and the slide unlocking key 404 is released after the night vision device slides to a required position.

Therefore, the adjustment of the up-down and turning angles, the front position and the rear position of the night vision device is realized.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
