Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1 —4. A night vision device viewing angle range adjustment structure, including a central control unit 100, an eyepiece 200, and an adjustment component. The adjustment component includes a fixed connector 301, an angle rotating component 302, and a bolt 303. First, the fixed connector 301 is rotatably connected to the central control unit 100. Specifically, the central control unit 100 is provided with a rotating mounting groove 101, and rotating openings 102 are provided on both sides of the rotating mounting groove 101. The fixed connector 301 is provided with a rotating connecting part 3011, and rotating shafts 3012 are provided at both ends of the rotating connecting part 3011. A damping sleeve 3013 is fitted on the rotating shaft 3012. The rotating connecting part 3011 is located in the rotating mounting groove 101, and the rotating shaft 3012 is rotatably connected in the rotating opening 102. The damping sleeve 3013 abuts against the side of the rotating mounting groove 101, so that the fixed connector 301 can rotate. Due to the setting of the damping sleeve 3013, the rotation has a damping effect.

[0018] Furthermore, the fixed connector 301 is rotatably connected to an angle rotating component via bolts 303. The angle rotating component is fixedly connected to the eyepiece 200. Specifically, the fixed connector 301 is provided with an angle adjustment part 3014, the angle adjustment part 3014 is provided with a mounting groove 3015, a screw hole post 3016 is fixedly connected in the mounting groove 3015, and a sealing groove 3017 is provided on the angle adjustment part 3014 around the mounting groove 3015. A sealing ring 304 is fitted in the sealing groove 3017.

[0019] The aforementioned angle rotating component 302 is fitted into the mounting groove 3015, and the sealing ring 304 abuts against the angle rotating component 302, so that the sealing ring 304 can form a seal between the angle rotating component and the angle adjustment part 3014. In addition, the angle rotating component 302 is provided with a mounting hole 3021, and the bolt 303 passes through the mounting hole 3021 and is threadedly connected to the screw hole post 3016. The mounting hole 3021 is provided with a damping ring 3022, and the nut of the bolt 303 abuts against the damping ring 3022. In this way, the fixed connecting component 301 and the angle rotating component 302 are connected by the bolt 303, and the angle rotating component 302 can rotate around the bolt 303. Under the action of the damping ring 3022, the rotation has a damping effect.

[0020] In addition, a fixing part 3023 is provided on the periphery of the angle rotating part 302, and a fixing hole 3024 is provided on the fixing part 3023. A connecting part 201 is provided on the eyepiece 200. The connecting part 201 is provided with a mounting screw hole that matches the fixing hole 3024. A fastening bolt 400 passes through the fixing hole 3024 and is threaded into the mounting screw hole, thereby realizing the fixed connection between the angle rotating part and the eyepiece 200.

[0021] In the above structure, the pitch angle of the eyepiece 200 can be adjusted by rotating the fixed connector 301. By rotating the eyepiece 200, the angle rotating component 302 can rotate on the fixed connector 301, thereby adjusting the field of view of the eyepiece 200. Through the above adjustment structure, the eyepiece 200 can be adjusted to multiple angles, thereby meeting the usage needs in different situations and achieving better performance.

[0022] Furthermore, an angle limiting post 3018 is fixedly connected in the mounting groove 3015, and an angle limiting groove 3025 is provided on the angle rotating component. The angle limiting post 3018 passes through the angle limiting groove 3025. In this way, the rotation angle of the eyepiece 200 is limited by the setting of the angle limiting post 3018 and the angle limiting groove 3025. Specifically, the limiting angle formed by the angle limiting post 3018 and the angle limiting groove 3025 is 15°.
