The storage rack 13 is a U-shaped structure. One end of the protective plate 6 is hingedly arranged at one end of the opening of the storage rack 13. A protective cover 14 is arranged on the protective plate 6. The protective cover 14 is arranged on the outer side of the lens of the night vision device body 2. Under the action of the force spring 12, a force is applied to the protective cover 14 toward the lens of the night vision device body 2, so that the protective cover 14 can stably cover the lens of the night vision device body 2. When the night vision device body 2 needs to be used, only a small-distance displacement force is applied to the storage rack 13 in the direction away from the force shell 7 to move the protective cover 14 away from the lens of the night vision device body 2, and then the protective cover 14 is rotated along the storage rack 13 to rotate the protective cover 14 to fit with the upper surface of the storage rack 13. At this time, there is no obstruction of the night vision device body 2 to the protective cover 14 and the protective plate 6, and the storage rack 13 drives the protective plate 6 to move toward the force shell 7.

[0036] Specifically, in the present embodiment, the pressing anti-rotation mechanism includes a fixed cylinder 15 and a sliding cylinder 16. The fixed cylinder 15 is fixedly arranged at one end of the vertical rotating shaft 3 close to the mounting plate 1, and the lower surface of the fixed cylinder 15 does not contact the upper surface of the mounting plate 1.

The pressing silicone pad 17 is configured to slide up and down with the sliding cylinder 16. The spacing of the pressing silicone pad 17 relative to the mounting plate 1 is adjustable. When the pressing silicone pad 17 is tightly fitted with the upper surface of the mounting plate 1 under the action of the sliding cylinder 16, the friction between the pressing silicone pad 17 and the mounting plate 1 increases, which can prevent the sliding cylinder 16 from rotating relative to the mounting plate 1, thereby preventing the fixed cylinder 15 and the vertical rotating shaft 3 from rotating relative to the mounting plate 1.

[0037] Specifically, in the present embodiment, a lifting groove 18 is provided on the top wall of the fixed cylinder 15, and a lifting column 19 is fixedly provided on the top wall of the sliding cylinder 16. The lifting column 19 penetrates and slides in the lifting groove 18. A pressing plate 20 is provided at the upper end of the lifting column 19. A lifting spring 21 is provided between the pressing plate 20 and the bottom wall of the lifting groove 18. The lifting spring 21 is sleeved on the lifting column 19.

At this time, The direction of the night vision device is adjusted by rotating the vertical shaft 3; when the pressure plate 20 is pressed and force is applied, the sliding cylinder 16 can be pushed to slide downward relative to the fixed cylinder 15. When the sliding cylinder 16 drives the pressing silicone pad 17 to contact the mounting plate 1, the pressing silicone pad 17 is pressed tightly against the mounting plate 1.

The pressing positioning spring 27 is sleeved on the pressing positioning column 26, and the pressing positioning spring 27 is pressed. The two ends are respectively connected to the limit plate 28 and the pressing and positioning plate 25.

The clamping positioning component is arranged in the clamping groove 35. The clamping positioning component and the clamping pushing component are arranged correspondingly. The clamping positioning component limits the vertical position of the clamping pushing component. Under the action of the clamping positioning component, the position of the clamping pushing component is limited, so that the clamping pushing component applies a stable clamping force to the clamping block 30.

[0043] Specifically, in the present embodiment, the clamping and pushing assembly includes a pushing slide bar 36 and a pushing spring 37. The pushing slide bar 36 is slidably arranged in the pushing slide groove 31. A limiting plate 2 38 is fixedly arranged on the upper end of the pushing slide bar 36.

When the positioning slide bar 40 is embedded in the upper group of positioning holes 39, the push slide bar 36 pushes the clamping block 30 to fit tightly on the transverse rotating shaft 4, and clamps the transverse rotating shaft 4 to prevent the transverse rotating shaft 4 from rotating. When the positioning slide bar 40 is embedded in the lower group of positioning holes 39, the push slide bar 36 drives the clamping block 30 away from the transverse rotating shaft 4.

[0045] Specifically, in this embodiment, a mounting hole 43 is provided on the mounting plate 1 , and the mounting seat 5 can be fixedly installed at a desired use position through the provision of the mounting hole 43 .

[0046] The specific working principle of the night vision device with high-efficiency protection function provided in this embodiment is as follows:

[0047] (1) First, fix the mounting plate 1 at the position where it is required to be used through the mounting hole 43;

[0048] (2) Lift the limit plate 28, which drives the pressing and positioning column 26 to move out of the positioning groove 24, and then rotate the pressing and positioning plate 25 to move the pressing and positioning plate 25 away from the pressing plate 20. Under the action of the lifting spring 21, the pressing plate 20 is forced to drive the lifting column 19 to move upward along the fixed tube 15. The lifting column 19 drives the sliding tube 16 and the pressing silicone pad 17 to move upward, and the pressing silicone pad 17 is away from the mounting plate 1. At this time, the limitation of the vertical shaft 3 can be released, and the vertical shaft 3 is rotated to adjust the use direction of the night vision device body 2;

[0049] After the adjustment is completed, the pressing plate 20 is pressed downward, and the pressing plate 20 drives the sliding cylinder 16 to slide down along the fixed cylinder 15 through the lifting column 19. During the sliding process, the engaging protrusion 23 slides down along the guide protrusion 22, and then the lower surface of the pressing plate 20 contacts the upper surface of the fixed cylinder 15. At this time, the pressing silicone pad 17 is stably fitted with the upper surface of the mounting plate 1. The limiting plate 28 is lifted to transfer the free end of the pressing positioning plate 25 to the top of the pressing plate 20, and the lower end of the pressing positioning column 26 is made to correspond to the positioning groove 24. The limiting plate 28 is released, and the pressing positioning column 26 is driven to be stably embedded in the positioning groove 24 under the action of the pressing positioning spring 27, ensuring that the pressing silicone pad 17 is in close contact with the upper surface temperature of the mounting plate 1.

[0050] (3) Then, the transverse rotating shaft 4 is rotated to drive the night vision device body 2 to adjust the angle. After the adjustment is completed, the limiting plate 3 42 is first pulled outward, and the limiting plate 3 42 drives the positioning slide bar 40 to slide out from a group of positioning holes 39 located below the push slide bar 36, and the limiting plate 2 38 is pressed downward. The limiting plate 2 38 drives the clamping block 30 to move downward through the push slide bar 36, and the clamping block 30 drives the clamping silicone pad 33 to be tightly attached to the transverse rotating shaft 4. Then, the limiting plate 2 38 is released. Under the action of the clamping positioning spring 41, the positioning slide bar 40 is embedded in a group of positioning holes 39 located above the push slide bar 36 to position the push slide bar 36, so that the clamping block 30 is stably attached to the transverse rotating shaft 4, and the transverse rotating shaft 4 is clamped and fixed from the upper and lower sides through the cooperation of the upper and lower sets of clamping anti-rotation assemblies to prevent the transverse rotating shaft 4 from rotating.

[0051] (4) When the night vision device body 2 needs to be used, it is only necessary to apply a force to the storage rack 13 in the direction away from the force shell 7 to move the protective cover 14 away from the lens of the night vision device body 2, and then rotate the protective cover 14 along the storage rack 13 to move the protective cover 14 away from the front side of the lens of the night vision device body 2.
