[0025] The threaded rod 5 is movably sleeved inside the No. 2 positioning seat 2, and the threaded rod 5 and the infrared sight body 3 are parallel to each other; by setting the threaded rod 5, when the position of the light shielding sleeve 7 is adjusted, the rotary motor 4 is started, so that the rotary motor 4 can drive the threaded rod 5 to rotate inside the extension sleeve 6, that is, the light shielding sleeve 7 is driven to move horizontally quickly through the extension sleeve 6, thereby achieving the effect of adjusting the distance between the light shielding sleeve 7 and the infrared sight body 3, thereby avoiding the problem of slow manual adjustment of the position of the light shielding sleeve 7, which makes the light shielding device inconvenient to use, thereby improving the practicality of the light shielding device.

[0026] The front shape of the No. 1 positioning seat 1 is U-shaped, and the No. 1 positioning seat 1 and the No. 2 positioning seat 2 are symmetrically distributed with the infrared sight body 3 as the symmetry axis; by setting the No. 1 positioning seat 1, when the shading device is installed and fixed, the infrared sight body 3 is sleeved on the inside of the No. 2 positioning seat 2, and the bolt 8 is rotated at this time, so that the bolt 8 can drive the No. 2 positioning seat 2 to be tightly squeezed on the top of the infrared sight body 3, so that the infrared sight body 3 can be clamped and fixed inside the No. 1 positioning seat 1, thereby achieving the convenience of installing and fixing the shading device.

[0032] The working principle of the shading device for an infrared sight provided by the utility model is as follows:

[0033] Step 1: First, when adjusting the position of the shading sleeve 7, start the rotary motor 4 so that the rotary motor 4 can drive the threaded rod 5 to rotate inside the extension sleeve 6, that is, drive the shading sleeve 7 to move horizontally quickly through the extension sleeve 6, thereby achieving the effect of adjusting the distance between the shading sleeve 7 and the infrared sight body 3, thereby avoiding the problem of manual adjustment of the position of the shading sleeve 7 being slow and causing inconvenience in using the shading device, thereby improving the practicality of the shading device. When installing and fixing the shading device, the infrared sight body 3 is sleeved inside the second positioning seat 2, and the bolt 8 is rotated at this time to make The bolt 8 drives the No. 2 positioning seat 2 to be tightly pressed on the top of the infrared sight body 3, so that the infrared sight body 3 can be clamped and fixed inside the No. 1 positioning seat 1, thereby achieving the convenience of installing and fixing the shading device. When the position of the shading sleeve 7 is quickly moved, the shading sleeve 7 can be tightly pressed on the side of the infrared sight body 3. At this time, the buffer sleeve 9 can buffer the impact force of the shading sleeve 7, thereby avoiding the problem of the fast-moving shading sleeve 7 hitting the side of the infrared sight body 3 and being damaged, thereby achieving the protection effect of the infrared sight body 3;

[0034] Step 2: When adjusting the position of the shading sleeve 7, the limit column 10 is able to limit the position of the horizontally moving shading sleeve 7, so as to avoid the problem of rotation and tilting of the shading sleeve 7 when it moves horizontally, thereby improving the stability of the shading sleeve 7 when it moves. When the shading sleeve 7 drives the limit column 10 to move horizontally, the sliding ball 11 is able to limit the horizontally moving limit column 10, so that the frequently moving limit column 10 and the No. 1 positioning seat 1 are rubbed against each other, thereby improving the smoothness of the movement of the limit column 10, that is, improving the smoothness of the movement of the shading sleeve 7. When the shading device is installed and fixed, the anti-slip sleeve 12 The infrared sight body 3 can be protected, so that the problem of damage to the infrared sight body 3 when the No. 1 positioning seat 1 and the No. 2 positioning seat 2 clamp and fix the infrared sight body 3 is avoided, thereby improving the protection effect of the infrared sight body 3. When it is necessary to close the light inlet of the infrared sight body 3, the shading plate 141 is flipped over, so that the shading plate 141 can drive the magnet column 142 to be adsorbed on the side of the shading sleeve 7, so that the shading plate 141 can close the shading sleeve 7, thereby achieving the effect of closing the light inlet of the infrared sight body 3, thereby bringing convenience to the opening and closing of the shading device.
