[0039] As Figure 1 — Figure 16 shown in the embodiment.

[0040] A sighting scope, comprising a scope body 1, on which a first screwing lead screw 21 is rotatably installed and extends into the interior thereof. Inside the scope body 1, a rotating seat 22 is rotatably installed with the two ends of the first screwing lead screw 21 as the rotation axes. A second screwing lead screw 23 is also rotatably installed on the scope body 1 and extends into the interior thereof. A first adjusting structure 8 is provided between the second screwing lead screw 23 and the rotating seat 22 to change the angle of the rotating seat 22 by rotating the second screwing lead screw 23. A spring plate 24 is fixedly installed on the end face of the rotating seat 22. Above the rotating seat 22, a carrier plate 25 fixedly connected to the spring plate 24 for carrying an optical element is provided. A second adjusting structure 9 is provided between the first screwing lead screw 21 and the carrier plate 25 to change the angle of the carrier plate 25 by rotating the first screwing lead screw 21.

[0041] Referring to Figure 1 and Figure 2 As shown, in this embodiment, mainly the position of one of the optical elements (the holographic reticle image plate 36 hereinafter) in the sighting optical path is changed to achieve the change of the position of the front sight, so as to correct the front sight for the influence brought by natural factors such as strong wind. Specifically, the position of the optical element is changed by changing the carrier plate 25 on which the optical element is installed. The position change is achieved by rotating the carrier plate 25 at a certain angle through the first adjusting structure 8 and the second adjusting structure 9. Specifically, the rotation directions of the carrier plate 25 driven by the first adjusting structure 8 and the second adjusting structure 9 are perpendicular to each other. Referring to Figure 2 As shown, if the first adjusting structure 8 rotates around the Y-axis, then the second adjusting structure 9 rotates around the X-axis. Thus, the two cooperate with each other to enable the optical element on the carrier plate 25 to meet the need for position change in space.

[0042] The first adjusting structure 8 includes a first compression spring 81 provided on the bottom surface of the rotating seat 22 away from its rotation axis direction, and further includes a first guiding inclined surface 82 opened on the upper surface of the rotating seat 22 and on the same side as the first compression spring 81. A first slider 83 adapted to the first guiding inclined surface 82 is drivingly installed on the second screwing lead screw 23. A guide post 84 is provided inside the first compression spring 81. A second compression spring 85 is provided on the outer surface of the second screwing lead screw 23 between the first slider 83 and the inner wall of the scope body 1.

[0043] Referring to Figure 2 and Figure 3As shown, the upward elastic force of the first compression spring 81 acts on the bottom surface of the rotating seat 22, so that the first guiding inclined surface 82 and the first slider 83 are always in contact. When rotation is required, first rotate the second screw 23 to drive the first slider 83 to move. Since the second screw 23 is in contact with the surface of the first guiding inclined surface 82, a limit is given to the first slider 83 in the rotation direction. Therefore, the first slider 83 will not rotate during the rotation of the second screw 23. As the angle of the first guiding inclined surface 82 changes, the rotating seat 22 is driven to rotate a certain angle around the rotating shaft, thereby changing the position of the optical element on the carrier plate 25.

[0044] The second adjusting structure 9 includes a second guiding inclined surface 93 provided on the bottom surface of the carrier plate 25. A second slider 91 adapted to the second guiding inclined surface 93 is drivingly installed on the first screw 21. The second slider 91 is located in the inner chute of the rotating seat 22. A tension spring 92 is provided between the end of the carrier plate 25 away from the spring piece 24 and the rotating seat 22. A third compression spring 94 is sleeved on the outer surface of the first screw 21. The third compression spring 94 is located between the second slider 91 and the inner wall of the chute of the rotating seat 22.

[0045] Refer to Figure 2 and Figure 3 As shown, the spring piece 24 has a certain elastic force and can undergo a certain deformation, that is, it can change with the change of the angle of the carrier plate 25. And under the downward pulling force of the tension spring 92, the bottom surface of the carrier plate 25 and the upper surface of the second slider 91 are always in contact, so as to give a circumferential limit to the second slider 91. Therefore, when the first screw 21 rotates, the second slider 91 will not be driven to rotate. Specifically, when adjustment is required, first rotate the first screw 21 to drive the second slider 91 to move. Under the change of the inclined surface height of the carrier plate 25, the position of the carrier plate 25 is changed, and the carrier plate 25 rotates around the spring piece 24 as the rotation center, so as to change the position of the carrier plate 25, thereby realizing the change of the position of the optical element.

[0046] The mirror body 1 includes a middle frame 11. An upper cover 12 is detachably and fixedly installed on the upper surface of the middle frame 11. A bottom cover 13 is detachably and fixedly installed on the bottom surface of the middle frame 11. An optical path structure 3 is also provided in the installation cavity formed by the middle frame 11, the upper cover 12 and the bottom cover 13. A convenient disassembly and assembly structure 4 for facilitating the disassembly and assembly of the telescopic sight is provided on the bottom cover 13.

[0047] The optical path structure 3 includes a fixing bracket 31 fixedly installed in the middle frame 11. A light source 32 and a reflecting mirror 33 for reflecting the light emitted by the light source 32 are fixedly installed on the fixing bracket 31. An installation bracket 34 is provided in the upper cover 12. A holographic diffraction filter 35 is installed at the top mounting position of the installation bracket 34. A holographic reticle image plate 36 is installed at the bottom mounting position of the installation bracket 34. A filter 37 is installed at the side mounting position of the installation bracket 34. An observation mirror 38 is also installed at the front and rear ends in the upper cover 12.

[0048] The observation window of the existing sight is usually made of holographic photosensitive material, and certain color changes will occur after long-term exposure to sunlight, such as black and gray, yellow and other phenomena.

[0049] Refer to Figure 5 、 Figure 6 、 Figure 14 and Figure 15 As shown in

[0050] It can be seen that first, the light from the light source 32 is reflected by the reflecting mirror 33 onto the holographic diffraction filter 35. The reflected light is filtered by the holographic diffraction filter 35. The light diffracted by the holographic diffraction filter 35 enters the holographic reticle image plate 36, and a diffraction aiming image is formed at the position of the holographic reticle image plate 36. Finally, the diffracted aiming image passes through the filter 37 and is reflected by the observation mirror 38 to the human eye, so that the human eye can see an infinitely distant aiming image. During use, only by making the sight and the object to be aimed on the same straight line can aiming be achieved. In this embodiment, an ordinary lens is only needed for the observation window, and the aiming image is reflected to the human eye through the filter 37, and there is no need for a window made of holographic photosensitive material. Compared with the existing scheme, the aiming image can be observed by using an ordinary lens or filter, and it can be used in the sun for a long time without discoloration.The detachable structure 4 includes a receiving groove 41 formed through the side surface of the bottom cover 13. A driven block 45 is arranged inside the receiving groove 41. An eccentric shaft 43 is rotatably installed on the other side of the bottom cover 13. A transmission rod 42 extending into the driven block 45 is rotatably installed on the rotating shaft of the eccentric shaft 43. A fixing block 46 fixedly connected to the transmission rod 42 is arranged in the stepped hole inside the driven block 45. A handle 44 is fixedly arranged on one side of the outer surface of the eccentric shaft 43. A rotating block 47 is rotatably installed on the side surface of the bottom cover 13 on the same side as the eccentric shaft 43. A clamping groove 49 is formed on the outer surface of the eccentric shaft 43. A clamping block 48 adapted to the clamping groove 49 and inserted into it is arranged at the end of the rotating block 47 close to the eccentric shaft 43. A limiting compression spring 410 is arranged between the inner side surface of the rotating block 47 far from the rotating shaft and the bottom cover 13. An avoidance groove 412 is arranged at the position of the receiving groove 41 on the bottom surface of the bottom cover 13. A fourth compression spring 411 is arranged between the driven block 45 and the inner wall of the avoidance groove 412.

[0051] Refer to Figure 5 , Figure 8 , Figure 9 , Figure 10 As shown, a corresponding dovetail groove structure is further formed on the bottom surface of the bottom cover 13 to facilitate the installation on corresponding objects (such as firearms). Specifically, for the convenience of installation, by driving the driven block 45 to move in the receiving groove 41, the driven block 45 is pressed against the object to be installed, thereby completing the fixed installation.

[0052] Specifically, during installation, first, the transmission rod 42 passes through the receiving groove 41 and extends into the driven block 45 in the receiving groove 41 on the other side of the bottom cover 13. Next, the fixing block 46 is screwed with the end of the transmission rod 42 located in the driven block 45, thereby realizing the limitation of the driven block 45. Under the elastic force of the fourth compression spring 411, the driven block 45 is always in contact with the fixing block 46. Next, the eccentric shaft 43 is rotated through the handle 44. Since the eccentric shaft 43 is an eccentric structure, when the eccentric shaft 43 rotates, it will pull the transmission rod 42 to move and then drive the driven block 45 to move towards the center, thereby realizing the clamping of the object to be installed in the dovetail groove. To further improve the clamping effect, a protrusion can be arranged at the bottom of the driven block 45 to firmly engage with the corresponding buckle groove on the object to be installed. After rotation, the clamping block 48 is engaged with the clamping groove 49 to prevent the eccentric shaft 43 from rotating and releasing the clamped installation state. Under the elastic force of the limiting compression spring 410, the clamping block 48 can always be located in the clamping groove 49 to realize the limitation.

[0053] When disassembly is required, only need to press the end of the rotating block 47 at the position of the limiting compression spring 410 to overcome the elastic force of the limiting compression spring 410 to make the clamping block 48 disengage from the clamping groove 49, and then only need to drive the eccentric shaft 43 to rotate in the reverse direction through the handle 44. Next, under the elastic force of the fourth compression spring 411, the driven block 45 moves away from the object to be installed, and the clamping and clamping state is released.

[0054] A limiting structure 7 is provided between the middle frame 11 and the knobs of the first screwing lead screw 21 and the second screwing lead screw 23. The limiting structure 7 includes a mounting hole 71 opened on the outer surface of the middle frame 11. A limiting spring 72 is arranged inside the mounting hole 71. A plurality of circumferentially evenly distributed limiting grooves 74 are opened on the side surface of the knob close to the middle frame 11. A limiting steel ball 73 is arranged between the limiting groove 74 and the limiting spring 72.

[0055] Refer to Figure 12 and Figure 13 As shown, in order to prevent the positions of the optical elements on the carrier plate 25 from changing due to accidental touching of the knobs of the first screwing lead screw 21 and the second screwing lead screw 23, a certain force is required to screw the first screwing lead screw 21 or the rotating base 22. Specifically, a resisting force is given to the limiting steel ball 73 by the limiting spring 72, so that the limiting steel ball 73 is limited in the limiting groove 74 on the inner side surface of the knob of the second screwing lead screw 23 and the first screwing lead screw 21. If the knob needs to be screwed, it is necessary to overcome the elastic force of the limiting spring 72 to screw, thus avoiding the problem of the sight offset caused by accidental touching.

[0056] A battery 5 is arranged inside the mirror body 1, and a circuit board 6 is also installed.

[0057] Refer to Figure 5 and Figure 7 As shown, electric energy is provided for the light source 32 by the battery 5, and the electric energy delivered to the light source 32 is controlled by the circuit board 6. In this embodiment, corresponding buttons (not shown in the figure) are also included, and the on and off or brightness level of the light source 32 is controlled through the buttons.

[0058] The present utility model also discloses an optical path aiming system, which is installed in any one of the above-mentioned aiming mirrors, including a light source, including a light source 32. A reflecting mirror 33 is arranged at the irradiation end of the light source 32. A holographic diffraction filter 35 for filtering the light from the light source 32 is arranged above the reflecting mirror 33. A holographic reticle image plate 36 is arranged at the reflection receiving end of the holographic diffraction filter 35. A filter 37 is arranged at the reflection receiving end of the holographic reticle image plate 36.

[0059] One side surface of the filter 37 is provided with a filter film, and the other side surface is provided with an antireflection film.

[0060] Refer to Figures 14 to 16 as shown Figure 14 It is the overall optical path diagram of the light source 32 in the first position state Figure 15 It is the overall optical path diagram of the light source 32 in the second position state. The light from the light source 32 is reflected to the holographic diffraction filter 35 through the reflector 33. The holographic diffraction filter 35 filters the light and injects the filtered diffracted light into the holographic reticle image plate 36. After receiving the light from the holographic diffraction filter 35 through the holographic reticle image plate 36, the aiming image is reproduced. Then, the aiming image is reflected by the filter 37 to the direction of human eye observation to form an infinitely distant aiming image, which can be observed by the human eye. Compared with the existing aiming scope, it does not require an observation window made of holographic photosensitive material, so it will not discolor even when used in the sun for a long time
