Detailed Implementation

[0029] 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 scope of protection of the present utility model.

[0030] Please see Figure 1 and Figure 2 This utility model provides a sight, including an objective lens unit 1, a main lens barrel 6, and an eyepiece unit 2. The objective lens unit 1 includes a lens assembly of the objective lens, a focusing lens 18, and a driving unit. The focusing lens 18 is used for focusing the lens assembly of the objective lens. The driving unit is used to drive the focusing lens 18 to move along the length of the main lens barrel 6. Both the focusing lens 18 and the lens assembly of the objective lens are disposed within the main lens barrel 6, and the eyepiece unit 2 is disposed at the end of the main lens barrel 6 away from the objective lens unit 1. In this embodiment, by setting the focusing lens 18 within the main lens barrel 6 and using a focusing guide pin 32 and a driving unit to drive the focusing lens 18 to move, the focusing function of the objective lens can be achieved. Specifically, the main tube 6 is a one-piece main tube 6, and the focusing lens 18 and the lens assembly of the objective lens are both located inside the main tube 6. The main tube 6 is elongated, and the focusing lens 18 can be moved along the length of the main tube 6 by a drive unit to focus the lens assembly of the objective lens.

[0031] Please see Figure 1 and Figure 2 The driving unit includes a focusing guide pin 32 that can drive the focusing lens 18 and a focusing handwheel component 31 that drives the focusing guide pin 32 to move. The focusing handwheel component 31 has a curved groove, and the direction of the curved groove is consistent with the length direction of the main lens barrel 6. The focusing guide pin 32 is movably disposed in the curved groove. In this embodiment, the driving method can be achieved by using the focusing handwheel component 31 in conjunction with the focusing guide pin 32. The focusing handwheel component 31 is located outside the main lens barrel 6. One end of the focusing guide pin 32 is located on the focusing handwheel component 31, and the other end is connected to the focusing lens frame 16. When the focusing handwheel component 31 is rotated, the focusing guide pin 32 moves within the curved groove of the focusing handwheel component 31, driving the focusing lens frame 16 to move linearly, thereby driving the focusing lens 18 in the focusing lens frame 16 to move, thus realizing the focal length change of the lens assembly of the objective lens.

[0032] Please see Figure 1 and Figure 2 The objective lens assembly includes a first objective lens 9 and a second objective lens 11, which are arranged sequentially along the length of the main lens barrel 6.

The first objective lens retaining ring 10 is threaded to the main lens barrel 6 and presses against the side of the objective lens sealing ring 7 for fixation, while ensuring that the objective lens unit 1 is sealed from the outside.

[0034] Please see Figure 1 and Figure 2 The objective lens unit 1 further includes a second objective lens frame 14 and a second objective lens retaining ring 12. The second objective lens frame 14 is fixed to the main lens barrel 6. The second objective lens 11 is installed inside the second objective lens frame 14. The second objective lens retaining ring 12 is connected to the second objective lens frame 14 and presses against the second objective lens 11. In this embodiment, the second objective lens frame 14 and the main lens barrel 6 are fixed by tolerance and threaded fit. The second objective lens 11 is installed inside the second objective lens frame 14. A second objective lens gasket 13 is added behind the second objective lens 11. The second objective lens retaining ring 12 is threadedly connected to the second objective lens frame 14 to fix the lens.

[0035] Please see Figure 1 and Figure 2This sight also includes a focusing spring 19 and a focusing frame 16 for mounting the focusing lens 18. The driving unit drives the focusing frame 16 to move. One end of the focusing spring 19 is sleeved on the focusing frame 16, and the other end of the focusing spring 19 abuts against the end face of the main lens barrel 6 away from the objective lens unit 1. In this embodiment, the focusing spring 19 is sleeved on the focusing frame 16, and one end face of the focusing spring 19 contacts the end face of the main lens barrel 6. The focusing spring 19 can be stretched or compressed when the focusing lens 18 moves linearly, so as to facilitate high-precision adjustment. Preferably, the focusing lens 18 is fixed in the focusing frame 16 by a focusing lens retaining ring 15. Specifically, the focusing lens retaining ring 15 fixes the focusing lens 18 in the focusing frame 16 by a threaded connection.

[0036] For further optimization of the above solution, please refer to [link / reference]. Figure 1 and Figure 2 The focusing lens frame 16 has mounting grooves at both its front and rear ends, and a focusing lens sealing ring 17 is fitted into each of the two mounting grooves. Both focusing lens sealing rings 17 contact the main lens barrel 6. In this embodiment, the two focusing lens sealing rings 17 are fitted into the mounting grooves at the front and rear ends of the focusing lens frame 16. The two focusing lens sealing rings 17 can increase the frictional damping of the focusing lens frame 16 during linear movement. This helps the scope maintain good optical axis stability under strong impact, while also maintaining good focusing feel.

[0037] Please see Figure 1 and Figure 2 The objective lens unit 1 further includes an image intensifier 22 and a limiting structure for locking and positioning the image intensifier 22.

The image tube positioning ring 20 is fixed in the groove of the main lens barrel 6. The image tube buffer pad 21 is fitted onto the image tube positioning ring 20. Then, the notch of the image intensifier 22 is aligned with the boss on the image tube positioning ring 20 and snapped in. The image tube pressure ring 23 is threaded onto the main lens barrel 6, pressing down on the image intensifier 22, thereby positioning and buffering, and cushioning axial impact. The image tube positioning ring 20, image tube buffer pad 21, and image tube pressure ring 23 are used to elastically lock the image intensifier tube and have an anti-rotation positioning function. It will not loosen under impact and vibration environments, and is simple to process and easy to assemble and disassemble. Figure 4, Figure 5 and Figure 6 The notch and protrusion can be V-shaped. The first objective lens 9 and the image intensifier 22 in the objective lens unit 1 are fixed together inside the main lens barrel 6 without disassembling the structural components, which can ensure high processing accuracy, ensure coaxiality, and reduce processing and assembly costs.

[0038] Please see Figure 1 and Figure 2 The objective lens unit 1 further includes a reticle 26 and a reticle adjustment component 29 for adjusting the attitude and position of the reticle 26. In this embodiment, the attitude and position of the reticle 26 can be adjusted by the reticle adjustment component 29. Specifically, the objective lens unit 1 also includes a reticle frame 27, in which the reticle 26 and a reticle illumination lamp 28 are installed, fixed with adhesive, and then threaded onto the reticle base 24. The reticle retaining ring 25 is threaded onto the main lens barrel 6 and blocks the reticle base 24, and is fixed with adhesive. The reticle adjustment component 29 adjusts the pitch and azimuth zero positions of the reticle 26 by pressing against the reticle base 24 in both up-down and left-right directions. A spring-loaded guide pin at a 45-degree angle on the opposite side presses against the reticle base 24 to increase adjustment damping, thereby improving shooting stability and accuracy.

[0039] Please see Figure 1 and Figure 3 The eyepiece unit 2 includes an eyepiece lens assembly, multiple eyepiece spacers, and multiple eyepiece sealing rings.
