Description

Technical Field

[0001] The utility model belongs to the technical field of night vision devices, in particular to a night vision device which is easy to assemble and disassemble. Background Art

[0002] Night vision goggles are an advanced optical electronic device, mainly used to provide visual enhancement in low-light or completely dark environments. They capture weak infrared or visible light and amplify it into visible images, allowing users to clearly observe targets at night or in extremely low light conditions. Night vision goggles are widely used in military, security, search and rescue, wildlife observation and other fields. Their core components include optical lenses, image intensifier tubes, infrared illuminators and displays. These components work together to convert weak light signals into enhanced electronic images, which are finally presented to the user, thereby greatly improving night vision. Night vision goggles not only improve the safety and effectiveness of night operations, but also play an important role in many fields of scientific research and daily life.

[0003] Existing night vision goggles lack a device that allows for easy disassembly and assembly. The problem with the above technology is that although existing night vision goggles provide excellent vision enhancement functions in low-light or completely dark environments, in actual use, due to the lack of a convenient disassembly and assembly device, users encounter many inconveniences when installing and disassembling night vision goggles. Traditional night vision goggles usually adopt a fixed installation method and need to be fixed with screws or other fasteners, which is not only time-consuming and labor-intensive, but also easy to damage the equipment. In emergency situations, the need for quick disassembly and assembly of night vision goggles is particularly urgent. In addition, the lack of a convenient disassembly and assembly device also limits the versatility and portability of night vision goggles. Users may need to remove the night vision goggles from the fixed bracket in different occasions, use them handheld or install them on other equipment, but the cumbersome disassembly and assembly process makes these operations difficult.

[0021] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0022] The structure of the present utility model is described in detail below with reference to the accompanying drawings.

[0023] like Figures 1 to 4As shown, the embodiment of the present invention provides a night vision device that is easy to disassemble and assemble, including a bracket 6, a fixing rod 7 and a night vision device 8. The inner wall of the bracket 6 is rotatably connected to the surface of the fixing rod 7. The upper end of the fixing rod 7 is fixedly connected to the lower end of the night vision device 8. A disassembly and assembly device 1 is provided at the upper end of the fixing rod 7. An auxiliary mechanism 2 is provided in the disassembly and assembly device 1.

The disassembly and assembly device 1 includes a connecting rod 101, a driving gear 102, a driven rack 103, a connecting plate 104, a clamping block 105 and a matching block 106.

A spring 3 is provided inside the clamping block 105, and two telescopic rods 4 are provided on both sides of the spring 3. One end of the spring 3 and the telescopic rod 4 are fixedly connected to the inner wall of the clamping block 105. Two protective boxes 5 are provided at both ends of the mounting plate 201. The surface of the protective box 5 is fixedly connected to the surface of the mounting plate 201. When the clamping block 105 moves outward, the spring 3 and the telescopic rod 4 will be stretched.

[0024] The working principle of this utility model:

[0025] When operating the night vision device 8 installation device, you first need to simultaneously rotate the connecting rods 101 on the protective boxes 5 on both sides of the mounting plate 201. This action will drive the driving gear 102 at the lower end of the connecting rod 101 to start rotating. It is worth noting that the surface of the driving gear 102 is meshed with the driven racks 103 on both sides. Therefore, when the driving gear 102 rotates, it will cause the two driven racks 103 to move in opposite directions. Since the four driven racks 103 on both sides are respectively fixed to the two connecting plates 104, this movement will cause the connecting plates 104 to expand outward. As the connecting plate 104 moves, the clamping block 105 fixed thereon will also move away from the surface of the mounting plate 201, creating space for the subsequent installation process of the night vision device 8. Next, the user can insert the matching block 106 at the bottom of the night vision device 8 into the sliding block 203 provided in the mounting plate 201 to achieve the initial positioning and fixation of the night vision device 8. Once the night vision device 8 is correctly placed in place, the connecting rod 101 can be released. At this time, the clamping block 105 will automatically retract inwards under the action of the internal spring 3 and the telescopic rod 4, gradually approaching the surface of the mounting plate 201. In this process, the clamping block 105 will automatically retract inwards under the action of the internal spring 3 and the telescopic rod 4, gradually approaching the surface of the mounting plate 201. The raised portion of the top of the holding block 105 will be embedded in the corresponding position of the matching block 106 at the bottom of the night vision device 8, thereby ensuring the safe fixation of the night vision device 8. The clamping blocks 105 on both sides act synchronously to provide a stable supporting force, ensuring the firm installation of the night vision device 8. In actual use, in order to adapt to different observation needs, the user may need to adjust the distance between the night vision device 8 and the eyes. At this time, this can be achieved by rotating the rotating rod 205 in the auxiliary box 204 below the mounting plate 201. The rotating rod 205 is connected to the adjusting screw 202 through a belt. When the rotating rod 205 is rotated, the adjusting screw 202 is rotated. When rotating, it will drive the adjusting screw 202 to rotate together. Due to the thread on the surface of the adjusting screw 202, this will cause the sliding block 203 installed thereon to slide back and forth along the direction of the mounting plate 201, thereby driving the entire night vision device 8 to move forward or backward, making it convenient for users to fine-tune according to their visual comfort. If the night vision device 8 needs to be removed, for example, for handheld use or replacement of other equipment, it is only necessary to rotate the connecting rod 101 again to allow the clamping blocks 105 on both sides to move outward again, releasing the fixing effect of the matching block 106 at the bottom of the night vision device 8, and the night vision device 8 can be easily removed.
