[0022] This embodiment provides a linkage adjustment mechanism for a laser ranging prism sight, including: A lens base 1, which is internally provided with a first accommodation cavity 10 and a second accommodation cavity 11. The first accommodation cavity 10 communicates with the second accommodation cavity 11 through a through groove 110, and the second accommodation cavity 11 is provided on the side of the lens base 1; A prism group 2, which is movably arranged in the first accommodation cavity 10. The prism group 2 can generate a reticle and a ranging function. The prism group 2 is existing, and this embodiment will not elaborate on it; A first adjustment mechanism, which is arranged on the side of the lens base 1 and its inner end abuts against the outside of the prism group 2, and is used to adjust the horizontal orientation of the prism group 2 to realize the left and right movement of the reticle; A second adjustment mechanism, which is arranged on the top of the lens base 1 and its inner end abuts against the outside of the prism group 2. The first adjustment mechanism and the second adjustment mechanism are vertically arranged, and the prism group 2 is adjusted in the horizontal and vertical directions respectively through the first adjustment mechanism and the second adjustment mechanism. Similarly, the second adjustment mechanism realizes the up and down movement of the reticle; The laser ranging module 3 is movably adjustable and disposed at one end close to the objective lens 4 within the second accommodation cavity 11 and generates a laser ranging center; It further includes a linkage mechanism, which is movably adjustable and disposed within the second accommodation cavity 11. One end of the linkage mechanism passes through the through slot 110 and is in linkage contact with the side of the prism group 2, and the other end is connected to one end of the laser ranging module 3. When the prism group 2 is adjusted, it swings, and drives the laser ranging module 3 to swing in the same direction through the linkage mechanism. That is, when the prism group 2 is adjusted alone, the linkage mechanism drives the laser ranging module 3 to move synchronously in the same direction. Only the prism group 2 needs to be adjusted alone, without the need to independently adjust the prism group 2 and the laser ranging module 3 simultaneously. The prism group 2 and the laser ranging module 3 form a collaborative system for synchronous adjustment, ensuring the coordination of optical aiming and distance measurement, enabling the shooter to directly obtain the corrected aiming point through optical imaging based on real-time distance data, and finally realizing the function of "ranging is aiming".

[0023] In the present invention, further, the first adjustment mechanism includes a first adjustment screw 5, the first adjustment screw 5 is rotatably adjustable and disposed on the side of the lens holder 1, and the inner end of the first adjustment screw 5 is inserted into the convex ring 20 on the outer side of the prism group 2. The second adjustment mechanism includes a second adjustment screw 6, the second adjustment screw 6 is rotatably adjustable and disposed on the upper part of the lens holder 1, and the inner end of the second adjustment screw 6 abuts against the convex ring 20. The outer surface of the convex ring 20 is an arc surface. By manually rotating and adjusting the first adjustment screw 5 and the second adjustment screw 6, the prism group 2 can be adjusted in the horizontal and vertical directions.

[0024] In the present invention, further, the linkage mechanism includes a lever 7, a lever rotating shaft 8, a first pin 13 and a second pin 14. A first positioning groove 9 is provided near the through groove 110 in the second accommodating cavity 11. The lever rotating shaft 8 is rotatably and swingably arranged in the first positioning groove 9. The lever rotating shaft 8 is fixed to the inner side of the middle of the lever 7 through a lever pin shaft 12, so that the lever 7 can rotate axially along the lever rotating shaft 8 and swing up and down. One end of the first pin 13 is in rolling fit connection with one end of the lever 7, and the other end of the first pin 13 abuts against the outer side of the inner end of the prism group 2. One end of the second pin 14 extends into the other end of the lever 7 for rolling fit connection, and the other end of the second pin 14 is in positioning connection with the laser ranging module 3. By respectively controlling the prism group 2 to generate horizontal swing or vertical swing through the first adjusting mechanism and the second adjusting mechanism, and driving the laser ranging module 3 to generate the same-direction swing as the prism group 2 through the linkage mechanism. That is, the lever 7 and the lever rotating shaft 8 are fixedly integrated. For example, when the prism group 2 is adjusted to swing to the left, the lever 7 and the lever rotating shaft 8 rotate to the left along the axis of the lever rotating shaft 8 as a whole. The first pin 13 always abuts against the outside of the prism group 2, and the second pin 14 is always in positioning connection with the laser ranging module 3, and at the same time drives the laser ranging module 3 to swing to the left. In addition, the same principle applies to the right, up or down directions. The up and down processes are just that the lever rotating shaft 8 performs swing actions, and the linkage process is the same.

[0025] In the present invention, further, the linkage mechanism further includes two first sliders 15. The two first sliders 15 are located in the first positioning groove 9 and are distributed on the upper and lower sides of the lever 7. The first sliders 15 are positioned and connected to the mirror base 1 through socket head cap screws. One end of the first slider 15 is in sliding fit connection with the outer side of the lever rotating shaft 8 with an inclined surface, and the other end of the first slider 15 is elastically abutted against the inner wall of the first positioning groove 9 through a first cylindrical compression spring 16. With the first cylindrical compression spring 16, the first slider 15 always abuts against the lever rotating shaft 8 to always position the lever rotating shaft 8. The sliding fit between the inclined surfaces of the two first sliders 15 and the outer side of the lever rotating shaft 8 forms a two-way dynamic wedge self-locking mechanism under the continuous pressure of the first cylindrical compression spring 16: when the lever rotating shaft 8 is subjected to external impact or vibration, its displacement trend will force the inclined surface of one side slider 15 to slide along the surface of the lever rotating shaft 8. At this time, the elastic force of the first cylindrical compression spring 16 presses the inclined surface tighter against the lever rotating shaft 8, generating a wedging force opposite to the displacement direction; at the same time, the other first slider 15 synchronously follows under the action of the first cylindrical compression spring 16 to form a symmetric constraint. This design enables any unexpected displacement of the lever rotating shaft 8 in any direction to be converted into self-increasing force clamping of the inclined surface to achieve instantaneous self-locking. During the adjustment operation, the torque applied manually can easily overcome this wedging force to ensure normal linkage is not affected.

[0026] In the present invention, further, a first connecting groove 70 and a second connecting groove 71 are respectively provided at both ends of the shift rod 7, the first pin 13 and the second pin 14 are both ball head pins, and the ball head of the first pin 13 rolls in the first connecting groove 70, and the ball head of the second pin 14 rolls in the second connecting groove 71. The prism group 2 and the laser ranging module 3 are distributed on both sides of the linkage mechanism, and the first pin 13 and the second pin 14 both have ball heads. Universal rolling adjustment can be achieved through the ball heads in the first connecting groove 70 and the second connecting groove 71, so that the linkage mechanism has a smooth movement stroke.

[0027] The spherical ends of the ball studs (first and second pins 13, 14) form a multi-degree-of-freedom floating fit with the connecting groove of the lever 7. When slight axial misalignment occurs between the prism assembly 2 and the laser ranging module 3 due to assembly tolerances, the ball studs can deflect and roll slightly within the groove, automatically adapting to misalignment and avoiding the localized stress concentration caused by forced alignment in traditional rigid links. This adaptive adjustment allows the linkage mechanism to maintain transmission accuracy while evenly dissipating the additional torque caused by assembly errors. This reduces component machining precision requirements and extends the life of the mechanism. The self-aligning nature of the ball studs ensures smooth, unobstructed linkage, especially when frequent adjustments or temperature fluctuations cause minor component deformation.

[0028] The up-and-down swing of the lever shaft 8 is precisely converted by the inclined surface of the first slider 15. When the lever shaft 8 is driven by the second adjustment mechanism to pitch, its outer curved surface contacts and slides relative to the inclined surface of the first slider 15, decomposing the rotational motion of the lever shaft 8 into linear displacement of the first slider 15. Simultaneously, the fifth cylindrical compression spring 23 continuously applies axial elastic force to the lever shaft 8, eliminating the clearance between the lever shaft 8 and the first positioning groove 9 and ensuring a constant center of swing. This combined "inclined surface guidance + elastic preload" mechanism allows even minute angular changes in the lever shaft 8 to be precisely converted into linear displacement of the end of the lever 7. This is then driven by the second pin 14 to synchronize the pitch of the laser ranging module 3, ultimately achieving strict synchronization of the vertical motion of the prism assembly 2 and the laser ranging module 3, with an error of less than 0.1 milliradian.

[0029] In the present invention, further, a first boss 90 is convexly provided in the first positioning groove 9, and the inner end surface of the lever 7 located on the back side of the second connecting groove 71 is elastically abutted with the first boss 90 through the second cylindrical compression spring 17. The second cylindrical compression spring 17 keeps the first pin 13 and the second pin 14 on the lever 7 always in contact and linkage with the prism group 2 and the laser ranging module 3 respectively.

[0030] In addition, through the collaborative design of the bidirectional inclined-plane slider and elastic preloading, the linkage mechanism unexpectedly achieves a self-stabilizing effect under a vibrating environment: when subjected to a lateral impact, the inclined plane of the first slider 15 converts the vibration energy into an additional pressing force on the rocker shaft 8, and forms a dynamic damping through the elastic energy storage of the first cylindrical compression spring 16, which not only suppresses the displacement drift in the non-adjusting direction, but also avoids the stress concentration of the rigid structure under the impact; at the same time, the rolling fit of the ball head pin not only maintains the universal linkage accuracy, but also its slight swing drives the first slider 15 to generate high-frequency micro-vibrations, automatically removing oxides or dust debris on the mating surface, significantly improving the reliability and maintenance-free performance under harsh environments. This dual effect of impact self-adaptive locking and self-cleaning anti-wear far exceeds the expected performance of ordinary linkage mechanisms.

[0031] In the present invention, further, a module adjustment mechanism is further included. The module adjustment mechanism includes a module rotating shaft 18, a second slider 19, and a third cylindrical compression spring 21. The module rotating shaft 18 is fixedly connected to a U-shaped elastic seat 30 on the laser ranging module 3 through a module pin 22. A second positioning groove 100 is formed on the lens holder 1. The module rotating shaft 18 is arranged in the second positioning groove 100 and can rotate axially or swing up and down along the module rotating shaft 18. Two second sliders 19 are provided and are respectively positioned and connected in the second positioning groove 100 by pan head screws and are distributed on the upper and lower sides of the U-shaped elastic seat 30. One side of the second slider 19 is an inclined plane and is in sliding fit with the outside of the module rotating shaft 18. The other end of the second slider 19 is elastically abutted against the inside of the second positioning groove 100 through a third cylindrical compression spring 21. A second boss 101 is provided in the second positioning groove 100. The back of the U-shaped elastic seat 30 is elastically abutted against the second boss 101 through a fourth cylindrical compression spring 300. The operating principles of the module adjustment mechanism and the part of the rocker 7 including the rocker shaft 8, the first slider 15, the first cylindrical compression spring 16, and the second cylindrical compression spring 17 are the same. Therefore, no further description will be given here.

[0032] In the present invention, further, fifth cylindrical compression springs 23 are installed inside the upper ends of the rocker shaft 8 and the module rotating shaft 18 respectively. The fifth cylindrical compression springs 23 partially extend out of the upper part and are elastically abutted against the inner walls of the upper parts of the first positioning groove 9 and the second positioning groove 100 respectively, so as to eliminate the axial clearances of the rocker shaft 8 and the module rotating shaft 18.

[0033] In addition to eliminating the axial clearance, the design of the fifth cylindrical compression spring 23 unexpectedly realizes the function of dynamic pressure adaptive adjustment: when the system is subjected to severe vibration or temperature change, resulting in a slight change in the fitting clearance between the first positioning groove 9 and the inner wall of the dial rod rotating shaft 8, the fifth cylindrical compression spring 23 can automatically compensate for the deformation and always maintain a stable elastic preload; at the same time, this floating support structure will generate a slight axial vibration when the dial rod rotating shaft 8 swings, effectively preventing the contact surface between the dial rod rotating shaft 8 and the first positioning groove 9 from sticking and wearing through high-frequency reciprocating motion, significantly improving the movement smoothness of the dial rod rotating shaft 8 and the service life of the mechanism. The dual effects of intelligent clearance compensation and self-lubricating anti-sticking enable the system to still maintain precise linkage during long-term use, far exceeding the performance of traditional rigid fixation.

[0034] In the present invention, further, a module cover 24 is further included. The module cover 24 is hermetically covered on the side of the lens holder 1 through a sealing ring 25 to cover the laser ranging module 3 and the linkage mechanism, and the waterproof property is improved through the sealing ring 25.

[0035] In the present invention, further, an eyepiece group 26 and a base 27 are further included. The eyepiece group 26 corresponds to the prism group 2 and is fixedly installed at one end of the lens holder 1, and the base 27 is fixed at the bottom of the lens holder 1.

[0036] The embodiments of the present application have been described above in conjunction with the accompanying drawings. Without conflict, the embodiments and the features in the embodiments in the present application can be combined with each other. The present application is not limited to the above specific implementation manners. The above specific implementation manners are only illustrative and not restrictive. Those of ordinary skill in the art, under the inspiration of the present application and without departing from the purpose of the present application and the scope protected by the claims, can also make many forms, all of which belong to the protection scope of the present application.
