Technical Field

[0002] With the continuous advancement of science and technology, laser optical sights have been widely used in military, hunting, precision measurement and high-end optical research fields. The core function of a laser sight is to provide users with high-precision target locking capabilities through the collaboration of laser beams and optical systems. However, with the diversification of usage requirements and the complexity of environmental conditions, traditional laser optical sights have gradually exposed some problems, such as beam offset, spot diffusion, insufficient brightness, and reduced aiming stability. These problems will not only affect the user's operating experience, but may also have an adverse effect on the success rate of the mission. Therefore, in order to solve these problems, calibration devices for laser optical sights came into being; There are still the following defects in specific use: 1. The deviation of the light beam will lead to inaccurate target positioning, especially in long-distance shooting or precision measurement, where a small angle deviation will turn into a significant positioning error; environmental vibration or thermal expansion and contraction may cause the alignment accuracy of the optical system or mechanical structure to decrease, thereby affecting the stability and focusing performance of the laser beam; vibration and thermal expansion and contraction will change the relative position of the optical components, causing the spot position of the light beam on the target to change.

[0003] 2. When the signal received by the reflector is weak, it is difficult for the detection equipment to distinguish the characteristics of the light beam, such as direction, intensity, etc.; in an automatic calibration or closed-loop feedback system, a weak signal will make the system unable to accurately adjust the direction or intensity of the light beam; a light beam with insufficient brightness may not form a clear light spot or light spot on the target.

[0022] The complete working principle and steps of the above embodiment are as follows: Initial qualification: Figure 1 to Figure 2As shown, during the operation of the optical sight, the functions of aiming, calibration and target locking are realized through the precise cooperation of the internal structure; when the user starts the optical sight body 1, the laser emitter 15 first generates a high-precision laser beam, and the laser is focused and calibrated through the optical lens group 11 to ensure that the beam is accurately propagated along the aiming axis. This process adjusts the light beam to the required direction and intensity through the refraction principle of the lens to ensure that it is stable and concentrated after being emitted. The optical window 12 serves as an observation port, providing a clear field of view, allowing the user to intuitively see the target area, and the window surface has anti-glare and scratch resistance to ensure long-term use.

[0023] The user can fine-tune the angle, intensity and focal position of the laser through the beam adjustment knob 13. The mechanical structure inside the beam adjustment knob 13 drives the lens group to move, thereby changing the direction or diffusion of the beam. The design of the beam adjustment knob 13 can lock the accuracy and avoid deviation caused by vibration or manual misoperation.

[0024] In the case of strong ambient light or large external interference, the protective structure 14 plays a shielding role to reduce the interference of stray light on the laser. At the same time, the protective structure 14 can also protect the precision components inside the laser transmitter 15 from external factors such as dust and moisture, thereby extending the life of the equipment.

[0025] During the entire aiming process, the light beam maintains high linearity and brightness when leaving the optical sight body 1 to ensure that the light spot on the target is clearly visible. If the target deviates or needs to be recalibrated, the user can quickly adjust the beam adjustment knob 13 and observe the optical window 12 to achieve the best aiming effect. After the laser is emitted, the optical window 12 displays the positioning of the target area, and the user confirms whether the operation is accurate through real-time observation; When using: The optical path guiding mechanism used to correct the directional deviation of the light beam and ensure that the light beam is transmitted along the predetermined path 2 steps: like Figure 3 to Figure 4As shown, when the laser emitter 15 generates a high-precision laser beam, the operator starts the motor housing 21 inside the protective structure 14, and then the short rod 22 rotatably connected to one end of the motor housing 21 will rotate, and the rotation of the short rod 22 will also drive the connecting rod 23 rotatably connected to one end thereof to move to a point of a lateral trajectory, so that the movement of the connecting rod 23 will also pull the inner rod 24 rotatably connected to one end thereof to rotate, so that the center plate 25 fixedly connected to one end of the inner rod 24 will reciprocate left and right with the rotation of the inner rod 24, thereby The left and right deflection of the core plate 25 will also pull the adapter plates 26 rotatably connected on both sides to perform left and right reciprocating deflection fluctuations, so that the left and right reciprocating deflection fluctuations of the adapter plate 26 will also pull the outer plate 27 rotatably connected on the outer side to move horizontally in the slide rail provided inside the obstacle bottom block 29, and at the same time, the movement of the connecting plate 28 will also drive the obstacle bottom block 29 fixedly connected at its bottom end to move synchronously, so that the wave-shaped movement trajectory distribution of the light beam emitted by the laser emitter 15 is achieved through the fluctuation deflection of the center plate 25, the adapter plate 26 and the outer plate 27; The light intensity feedback mechanism for real-time reflection of part of the light beam and monitoring its brightness has three steps: like Figures 5 and 6 As shown, when the center plate 25 rotates, the cam 31 fixedly connected to the outer wall of one side thereof will rotate, and then the rotation of the cam 31 will press down and push the contact block 34 that abuts against its lower end to move downward. At the same time, the rotation of the cam 31 will also drive the wedge wheel 32 rotatably connected to the outer wall of one side thereof to rotate. In this way, the rotation of the wedge wheel 32 will cause the convex arc surface set at its lower end to first slide on the concave arc surface of the outer wall of the half shaft disk 33. When the wedge wheel 32 rotates until the cylindrical obstacle column set at its top is clamped at the outer wall of the half shaft disk 33, the cylindrical obstacle column will push the half shaft disk 33 to rotate. Therefore, the rotation of the half shaft disk 33 will drive the disk 314 fixedly connected to its upper end to rotate. In addition, the downward movement of the contact block 34 will drive the connecting rod 35 of the outer wall of one side thereof to move and deflect synchronously, and then the connecting rod 35 The deflection of the crank 36 will also pull the crank 36 connected to one end to rotate, so that the rotation of the crank 36 drives the deflection rod 37 connected to one end to rotate, so that the rotation of the deflection rod 37 will make the rotating rod 38 connected to one end to rotate, and the double-headed buckle 39 fixedly connected to one end of the rotating rod 38 synchronously deflect, and then the deflection of the double-headed buckle 39 will pull the swing rod 310 connected to one end to rotate up and down, thereby driving the extrusion block 311 fixedly connected to one end to slide on the outer wall of the fixed column 312, and the up and down movement of the extrusion block 311 will push the reflector 315 that contacts the top end to move up and down on the surface of the disk 314, and finally realize the light speed reflected to the surface of the laser emitter 15 after divergence through the phosphor covered on the surface of 415, which is convenient for operators to judge its lighting effect; The light speed expansion mechanism for controlling the energy distribution of the light beam and thus increasing the power density of the light beam has 4 steps: like Figures 7 and 8 As shown, when the obstacle bottom block 29 follows the connecting plate 28 in the movement, the obstacle bottom block 29 moves to trigger the touch switch 43, and then the electric telescopic rod 42 moves to one side and extends, so that the support block 41 fixedly connected to the outer wall of the electric telescopic rod 42 will move and extend synchronously with the electric telescopic rod 42, thereby the card rod 45 engaged in the square groove opened on the upper surface of the electric telescopic rod 42 will be deflected and pushed along with the movement of the support block 41, so that the deflection of the card rod 45 will drive the double-headed rod 46 rotatably connected at one end thereof to rotate, so that the rotation of the double-headed rod 46 will also drive the deflected rod 47 rotatably connected at one end thereof to rotate, and then the rod-belt blocking block 48 rotatably connected at one end of the deflected rod 47 will be deflected and pulled together, and the long rod 49 rotatably connected at the other end of the double-headed rod 46 will synchronously pull the symmetrically installed rod-belt blocking block 48 to move in the opposite direction, thereby ensuring that the contact area between the light beam and the transmission medium is appropriate.
