A linkage adjustment mechanism for a laser ranging prism sight

Abstract

The present invention provides a linkage adjustment mechanism for a laser ranging prism sight, comprising: a base, a prism assembly, a first adjustment mechanism, a second adjustment mechanism, a laser ranging module, and a linkage mechanism. A linkage mechanism is provided within the base, interlocking the prism assembly and the laser ranging module. The base is also provided with a first adjustment mechanism and a second adjustment mechanism for adjusting the prism assembly horizontally and vertically. During adjustment of the first and second adjustment mechanisms, the position of the reticle generated by the prism assembly is adjusted horizontally and vertically, and the linkage mechanism simultaneously drives the laser ranging module to swing in the same direction as the prism assembly. This allows the prism assembly and the laser ranging module to form a coordinated system for synchronous adjustment, ensuring coordination between optical aiming and distance measurement. This allows the shooter to directly obtain a corrected aiming point through optical imaging based on real-time distance data, thus achieving a "range measurement and aiming" function.

[0033] This embodiment provides a linkage adjustment mechanism for a laser ranging prism sight, comprising:

[0034] The mirror base 1 is provided with a first accommodating cavity 10 and a second accommodating cavity 11 therein. The first accommodating cavity 10 and the second accommodating cavity 11 are communicated with each other through a through groove 110. The second accommodating cavity 11 is provided on the side of the mirror base 1.

[0035] a prism assembly 2, movably disposed within the first accommodating cavity 10, capable of generating a reticle and performing distance measurement functions. The prism assembly 2 is already known and will not be described in detail in this embodiment;

[0036] A first adjustment mechanism is provided on the side of the lens holder 1 and has its inner end in contact with the outside of the prism assembly 2, and is used to adjust the horizontal position of the prism assembly 2 to achieve left and right movement of the reticle;

[0037] a second adjustment mechanism, disposed on the top of the lens holder 1 and with its inner end abutting against the exterior of the prism assembly 2; the first adjustment mechanism and the second adjustment mechanism being disposed perpendicularly to each other, and adjusting the prism assembly 2 in the horizontal and vertical directions respectively by the first adjustment mechanism and the second adjustment mechanism; similarly, the second adjustment mechanism enables the reticle to move up and down;

[0038] The laser distance measuring module 3 is movably arranged in the second accommodating cavity 11 and close to one end of the objective lens 4 to generate the laser distance measuring center;

[0039] It also includes a linkage mechanism, which is movably adjusted and arranged in the second accommodating 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, so that the prism group 2 swings when adjusted 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 in the same direction synchronously. It is sufficient to adjust the prism group 2 alone, and there is no need to independently adjust the prism group 2 and the laser ranging module 3 at the same time, so that 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, so that the shooter can directly obtain the corrected aiming point through optical imaging based on real-time distance data, and finally realize the function of "ranging and aiming".

[0040] In the present invention, further, the first adjustment mechanism includes a first adjustment pin 5, which is rotatably adjusted and arranged on the side of the mirror base 1, and the inner end of the first adjustment pin 5 is plugged into the convex ring 20 on the outside of the prism group 2. The second adjustment mechanism includes a second adjustment pin 6, which is rotatably adjusted and arranged on the upper part of the mirror base 1, and the inner end of the second adjustment pin 6 is in contact with the convex ring 20, and the outer part of the convex ring 20 is an arc-shaped surface. The first adjustment pin 5 and the second adjustment pin 6 are manually rotated and adjusted to adjust the prism group 2 horizontally and vertically.

[0041] In the present invention, further, the linkage mechanism includes a lever 7, a lever shaft 8, a first pin 13 and a second pin 14. A first positioning groove 9 is provided in the second accommodating cavity 11 near the through groove 110. The lever shaft 8 is rotatable and swingable in the first positioning groove 9. The lever shaft 8 is fixed to the inner side of the middle part of the lever 7 by the lever pin 12, so that the lever 7 can rotate and swing up and down along the axial direction of the lever shaft 8. One end of the first pin 13 is connected to one end of the lever 7 in a rolling fit, and the other end of the first pin 13 abuts the outer side of the inner end of the prism group 2. One end of the second pin 14 extends into the inner side of the other end of the lever 7 and is connected in a rolling fit. The other end of the second pin 14 is connected to the laser ranging module 3 positioning connection, the first adjustment mechanism and the second adjustment mechanism respectively control the prism group 2 to swing horizontally or vertically, and drive the laser ranging module 3 to swing in the same direction as the prism group 2 through the linkage mechanism. That is, the lever 7 and the lever shaft 8 are fixed and integrated. For example, when the prism group 2 is adjusted to swing left, the lever 7 and the lever shaft 8 rotate left along the axis of the lever shaft 8. The first pin 13 always abuts the outside of the prism group 2, and the second pin 14 is always positioned and connected with the laser ranging module 3, while driving the laser ranging module 3 to swing left. In addition, the same principle applies to rightward, upward or downward movement. The upward and downward processes are just the swinging movement of the lever shaft 8. The linkage process is similar.

[0042] In the present invention, further, the linkage mechanism also 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, and the first slider 15 is positioned and connected to the mirror base 1 through a pan head screw, one end of the first slider 15 is inclined and slidably connected to the outer side of the lever shaft 8, and the other end of the first slider 15 is elastically abutted against the inner wall of the first positioning groove 9 through the first cylindrical compression spring 16. With the first cylindrical compression spring 16, the first slider 15 is always pressed against the lever shaft 8, and the lever shaft 8 is always positioned. The inclined surfaces of the two first sliders 15 slide against the outer side of the lever shaft 8, and under the continuous pressure of the first cylindrical compression spring 16, form a bidirectional dynamic wedge-shaped self-locking mechanism. When the lever shaft 8 is subjected to external impact or vibration, its displacement forces the inclined surface of one slider 15 to slide along the surface of the lever shaft 8. At this time, the elastic force of the first cylindrical compression spring 16 presses the inclined surface more tightly against the lever shaft 8, generating a wedge-locking force opposite to the displacement direction. Simultaneously, the first slider 15 on the other side, under the action of the first cylindrical compression spring 16, follows suit, forming a symmetrical constraint. This design ensures that any unintended displacement of the lever shaft 8 in any direction is converted into self-amplifying clamping of the inclined surfaces, achieving instantaneous self-locking. During adjustment, manually applied torque can easily overcome this wedge-locking force, ensuring normal linkage is not affected.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] Furthermore, the linkage mechanism, through the collaborative design of a bidirectional inclined slider and elastic preload, unexpectedly achieves a self-stabilizing effect in vibrating environments. When subjected to a lateral impact, the inclined surface of the first slider 15 converts vibration energy into additional compressive force on the lever shaft 8. The elastic energy storage of the first cylindrical compression spring 16 creates dynamic damping, suppressing displacement drift in non-adjustable directions while avoiding stress concentration in the rigid structure under impact. Simultaneously, the rolling fit of the ball stud maintains universal joint accuracy while its slight oscillation drives high-frequency micro-motion in the first slider 15, automatically removing oxides and dust from the mating surfaces and significantly improving reliability and maintenance-free operation in harsh environments. This dual effect of impact-adaptive locking and self-cleaning anti-wear far exceeds the expected performance of conventional linkage mechanisms.

[0048] The present invention further includes a module adjustment mechanism, which includes a module shaft 18, a second slider 19 and a third cylindrical compression spring 21. The module shaft 18 is fixedly connected to the U-shaped spring seat 30 on the laser ranging module 3 through a module pin 22. A second positioning groove 100 is provided on the lens base 1. The module shaft 18 is arranged in the second positioning groove 100 to realize axial rotation or up and down swing along the module 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 distributed on the U-shaped spring seat 30. On the upper and lower sides, one side of the second slider 19 is an inclined surface and slides with the outside of the module shaft 18. The other end of the second slider 19 is elastically abutted against the inside of the second positioning groove 100 through the third cylindrical compression spring 21. A second boss 101 is provided in the second positioning groove 100. The back of the U-shaped spring seat 30 is elastically abutted against the second boss 101 through the fourth cylindrical compression spring 300. The module adjustment mechanism and the lever shaft 8, the first slider 15 and the first cylindrical compression spring 16 and the second cylindrical compression spring 17 on the above-mentioned lever 7 have the same operating principles. Therefore, they will not be described in detail here.

[0049] In the present invention, further, a fifth cylindrical compression spring 23 is installed inside the upper end of the lever shaft 8 and the module shaft 18. The fifth cylindrical compression spring 23 partially extends out of the upper part and elastically abuts against the upper inner wall of the first positioning groove 9 and the upper inner wall of the second positioning groove 100, respectively, thereby eliminating the axial clearance between the lever shaft 8 and the module shaft 18.

[0050] In addition to eliminating axial play, the design of the fifth cylindrical compression spring 23 also unexpectedly enables dynamic pressure adaptive regulation: when the system is subjected to severe vibration or temperature fluctuations, causing the clearance between the first positioning groove 9 and the inner wall of the shift lever shaft 8 to slightly change, the fifth cylindrical compression spring 23 automatically compensates for this deformation, maintaining a stable elastic preload. Furthermore, this floating support structure generates slight axial vibrations as the shift lever shaft 8 swings. This high-frequency reciprocating motion effectively prevents viscous wear on the contact surface between the shift lever shaft 8 and the first positioning groove 9, significantly improving the smoothness of the shift lever shaft 8 and the service life of the mechanism. This dual effect of intelligent clearance compensation and self-lubrication to prevent seizure ensures precise linkage during long-term use, far exceeding the performance of traditional rigid fixation.

[0051] The present invention further includes a module cover 24 , which is sealed 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 improves the waterproof performance through the sealing ring 25 .

[0052] The present invention further includes an eyepiece assembly 26 and a base 27 . The eyepiece assembly 26 corresponds to the prism assembly 2 and is fixedly mounted on one end of the lens holder 1 . The base 27 is fixed to the bottom of the lens holder 1 .

[0053] The embodiments of the present application are described above in conjunction with the accompanying drawings. Unless there is a conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of this application, ordinary technicians in this field can also make many forms without departing from the purpose of this application and the scope of protection of the claims, all of which are within the protection of this application.
