Description

Technical Field

[0001] The utility model relates to the technical field of night vision, in particular to a portable infrared night vision device. Background Art

[0002] Night vision technology is a technology that can observe targets at night and obtain target images visible to the human eye. There are three types of night vision technologies currently in use: low-light night vision technology, active infrared night vision technology, and infrared thermal imaging technology.

[0003] Infrared night vision goggles are a type of night vision technology equipment that uses infrared radiation to observe and record images in the environment. It works by using the heat energy (infrared radiation) emitted by objects rather than relying on external light sources. Infrared night vision goggles can detect objects that still emit heat in very dark environments, and then convert this heat into images, allowing users to see objects clearly at night or in low-light environments.

[0004] In the prior art, a lanyard is generally provided for the convenience of the staff to carry and use, but the length of these lanyards cannot be adjusted according to the carrying method. The inability to adjust the length of the lanyard means that the night vision device cannot comfortably adapt to people of different body shapes, which may lead to inappropriate or uncomfortable wearing. Therefore, a portable infrared night vision device is proposed to solve the above problem. Utility Model Content

The ends of the two rotating rods 8 away from the cross plate 7 are rotatably connected to a connecting block 9. The rotating rod 8 connects the cross plate 7 and the connecting block 9. Because the length of the rotating rod 8 cannot be changed, when the cross plate 7 moves, the two rotating rods 8 will only rotate, which will cause the connecting block 9 is driven by the rotating rod 8 to move, and one side of the two connecting blocks 9 is fixedly connected with a card block 10, and the card block 10 is connected to the connecting block 9, so that when the connecting block 9 is driven, the card block 10 will be driven to move together, and the end of the cross plate 7 away from the push rod 6 is fixedly connected with a compression spring 14, and the interior of the cross plate 7 is slidably connected with a slide rod 13, and the end of the slide rod 13 away from the cross plate 7 is fixedly connected with a baffle 15, the slide rod 13 is used to support the movement of the cross plate 7, and the compression spring 14 is used to provide reset movement and support The force is used to make the cross plate 7 reset and move, the baffle 15 is used to fix the position of the slide bar 13 and cooperate with the cross plate 7 to squeeze the compression spring 14, the mounting plate 3 is fixedly connected to the side away from the objective lens 2 with two mounting rods 4, the two mounting rods 4 are slidably connected to the inside of the housing 1, and the upper and lower sides of the two mounting rods 4 are provided with card slots 12, the mounting rod 4 is used to insert into the inside of the housing 1, and it is convenient to install the objective lens 2, the two card blocks 10 are respectively slidably connected to the inside of the two slots 21, and the card blocks 10 are inserted into the slots 21 opened by the mounting rods 4, so that the card blocks 10 form a limit for the mounting rods 4, so that the mounting rods 4 are fixed to the inside of the housing 1, the upper and lower sides of the interior of the housing 1 are fixedly connected with support rods 11, the two card blocks 10 are respectively slidably connected to the outer periphery of the two support rods 11, the support rods 11 are used to support the card blocks 10 to move, so that the card blocks 10 can only move vertically along the support rods 11, and the push rod 6 is fixedly connected to one end away from the cross plate 7 with a push plate 5, and the push plate 5 is used to control the movement of the push rod 6.

[0035] Working principle: When carrying the infrared night vision device, the pull plate 17 drives the pull rod 18 to move. When the pull rod 18 moves, the limit plate 20 moves together and squeezes the spring 19. When the pull rod 18 slides out of the slot 21 opened by the hanging strap 16, the hanging strap 16 can be adjusted, and then the appropriate position of the hanging strap 16 is selected according to the slot 21 opened, and the pull plate 17 can be released. The spring 19 loses the squeezing of the limit plate 20 and generates a thrust to push the limit plate 20 to move, and then the limit plate 20 drives the pull rod 18 to move, so that the pull rod 18 is inserted into the slot 21 to form the shape of the hanging strap 16. The two push plates 5 are then pressed, and the two push rods 6 drive the two cross plates 7 to move. The cross plates 7 will move along the slide bar 13 to squeeze the compression spring 14. Then the rotating rods 8 at the upper and lower ends of the cross plate 7 rotate, so that the two connecting blocks 9 drive the card blocks 10 to move along the support rod 11. Then the mounting rod 4 is inserted into the interior of the casing 1, and the push plates 5 are released. The compression spring 14 resets and moves to generate thrust to push the cross plate 7 to move. The two rotating rods 8 will drive the two card blocks 10 to move toward each other, so that the two card blocks 10 are inserted into the interior of the card slot 12, thereby completing the assembly of the objective lens 2 and the casing 1.
