[0018] 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.

[0019] Please see Figure 1-4 As shown, a laser measurement aiming device includes a lens tube 1, a mounting bracket 4 mounted on the lens tube 1, a connecting seat 5 placed on the mounting bracket 4, a laser rangefinder mounted on the connecting seat 5, a laser emitter 6 and a laser receiver 7 mounted on the laser rangefinder, and the connecting seat 5 is electrically connected to the mounting bracket 4 through electrode plates. Two sets of fixing seats 8 are symmetrically mounted on the side wall of the lens tube 1. The fixing seats 8 have plate grooves 9 and assembly grooves 10. A limit plate 11 is slidably connected in the assembly groove 10, and a limiting plate 11 is mounted on the limit plate 11. There is a locking block 12. Multiple sets of springs 28 are installed between the limiting plate 11 and the inner wall of the assembly groove 10. A connecting rod 13 is installed on the limiting plate 11, and the connecting rod 13 passes through the side wall of the assembly groove 10. A driving block 14 is installed at the other end of the connecting rod 13. A locking plate 15 is placed in the plate groove 9. A locking groove 16 is opened in the locking plate 15. A fixing plate 17 is installed on the locking plate 15. A sunshade 18 is installed on the fixing plate 17. An objective lens 2, a transparent digital display reticle, and an eyepiece 3 are installed inside the lens tube 1. The eyepiece 3 is coaxially aligned, and the mounting bracket 4 contains a circuit board with a laser rangefinder module and a ballistic calculation chip. The circuit board is connected to a transparent digital reticle via internal circuitry. The scope tube 1 is equipped with a magnification ring 19 and a refractive ring 20, as well as an adjustment handwheel 21 and a side focus handwheel 22. During operation, existing aiming equipment suffers from poor accuracy due to the inability to shield the laser beam from sunlight, leading to interference. This is addressed by using a sunshade... The snap-fit ​​plate 15 on plate 18 is inserted into the plate groove 9 of the fixing seat 8. The snap-fit ​​plate 15 pushes the snap-fit ​​block 12 to slide horizontally into the assembly groove 10. When the snap-fit ​​plate 15 is fully inserted into the plate groove 9, the spring 28 pushes the limiting plate 11 to move horizontally towards the snap-fit ​​plate 15. The limiting plate 11 pushes the snap-fit ​​block 12 to move horizontally towards the snap-fit ​​plate 15, so that the snap-fit ​​block 12 is locked in the snap-fit ​​groove 16 of the snap-fit ​​plate 15, thereby realizing the snap-fit ​​and fixing of the snap-fit ​​plate 15 and the fixed installation of the sunshade 18. At this time, the sunshade 18 blocks the sunlight.

[0020] When using the aiming device, the target is aimed through the objective lens 2. Then, the laser rangefinder operates, emitting an infrared beam through the laser emitter 6. The infrared beam is reflected when it encounters the target, and the reflected infrared beam is then received by the laser receiver 7. The integrated circuit calculates the target distance based on the time of the infrared beam being emitted and received, as well as the speed of light. After ranging the target, the ballistic calculation program built into the integrated circuit calculates the ballistic compensation in real time and displays the result in real time as numbers and red dots on the transparent digital reticle inside the scope. Simply move the red dot to the target and re-aim, achieving precise aiming at the target. During this process, the installation of the sunshade 18 avoids interference from sunlight on the laser beam, which helps improve the accuracy of laser measurement.

[0021] Please see Figure 5 As shown, a rod seat 23 is installed on the side wall of the mounting frame 4, a screw 24 passes through the rod seat 23, a knob 25 is installed on the screw 24, and a positioning block 26 is rotatably installed on the other end of the screw 24. The positioning block 26 is slidably connected to the side wall of the mounting frame 4, and a baffle 27 is slidably connected to the mounting frame 4. During operation, existing aiming equipment usually fixes the laser rangefinder with screws, which requires tools and is cumbersome, resulting in poor ease of installation of the laser rangefinder. By placing the connecting seat 5 of the laser rangefinder on the mounting frame 4, and then pushing the baffle 27, the baffle 27 limits the connecting seat 5. Then, rotating the knob 25 drives the screw 24 to rotate. The screw 24 rotates on the rod seat 23 and moves horizontally. The screw 24 drives the positioning block 26 to move horizontally. The positioning block 26 positions one side of the baffle 27, realizing convenient installation of the laser rangefinder and improving the ease of installation of the laser rangefinder.

[0022] Working principle: In existing aiming equipment, during laser measurement, the laser beam is easily interfered with by sunlight because it cannot be shielded, resulting in poor accuracy. By inserting the snap-fit ​​plate 15 on the sunshade 18 into the slot 9 of the fixing base 8, the snap-fit ​​plate 15 pushes the snap-fit ​​block 12 to slide horizontally into the assembly slot 10. When the snap-fit ​​plate 15 is fully inserted into the slot 9, the spring 28 pushes the limiting plate 11 to move horizontally towards the snap-fit ​​plate 15, and the limiting plate 11 pushes the snap-fit ​​block 12 to move horizontally towards the snap-fit ​​plate 15. This causes the locking block 12 to engage within the slot 16 of the locking plate 15, thus securing the locking plate 15 and fixing the sunshade 18 in place. The sunshade 18 then blocks sunlight. When using the aiming device, the objective lens 2 is used to aim at the target. The laser rangefinder then operates, emitting an infrared beam through the laser emitter 6. The infrared beam is reflected upon encountering the target and is then received by the laser receiver 7. The integrated circuit calculates the target value based on the time it takes for the infrared beam to be emitted and received, as well as the speed of light. After measuring the distance to the target, the ballistic calculation program built into the integrated circuit calculates the ballistic compensation in real time and displays the result in real time as numbers and red dots on the transparent digital reticle inside the scope. Simply move the red dot to the target and re-aim, achieving precise aiming. During this process, the installation of the sunshade 18 prevents interference from sunlight on the laser beam, improving the accuracy of laser measurement. Existing aiming devices typically use screws to fix the laser rangefinder, requiring tools and being cumbersome, resulting in poor ease of installation. By placing the laser rangefinder's connecting seat 5 on the mounting bracket 4, then pushing the baffle 27 to limit the connecting seat 5, and then rotating the knob 25 to rotate the screw 24, which rotates on the rod seat 23 and moves horizontally, the screw 24 moves the positioning block 26 horizontally, positioning one side of the baffle 27. This facilitates convenient installation of the laser rangefinder, significantly improving its ease of installation.
