Abstract

This invention provides a linkage adjustment mechanism for a laser rangefinder red dot sight, including a mount, an inner tube, a first adjustment mechanism, and a second adjustment mechanism. The first and second adjustment mechanisms are used to radially adjust the movement of the inner tube, thereby adjusting the horizontal and vertical movement of the red dot sight. A laser rangefinder module is disposed on the side of the inner tube. The laser rangefinder module emits a laser, generates a rangefinder center, and measures distance. The laser rangefinder module includes a third adjustment mechanism and a fourth adjustment mechanism. The third adjustment mechanism adjusts the horizontal movement of the rangefinder center, and the fourth adjustment mechanism adjusts the vertical movement of the rangefinder center, ensuring that the rangefinder center and the red dot sight are aligned and overlapped. By adjusting the horizontal displacement of the red dot sight through the first adjustment mechanism and the vertical displacement of the red dot sight through the second adjustment mechanism, and simultaneously coordinating with the laser rangefinder module to adjust the horizontal and vertical displacements of the rangefinder center, the linkage between these mechanisms ensures that the red dot sight and the rangefinder center are aligned and overlapped.

Description

Technical Field

[0001] This invention belongs to the field of aiming scope technology, and particularly relates to a linkage adjustment mechanism for a laser rangefinder red dot sight. Background Technology

[0002] A scope (also known as an optical sight, aiming device, or rifle scope) is an optical instrument used to improve shooting accuracy. It is typically mounted on firearms, crossbows, telescopes, stage lights, or other shooting weapons. Its core function is to help the user observe the target more clearly and improve the hit rate.

[0003] Since the scope's optical system and the laser rangefinder module's optical system are two independent optical systems, in actual use, prolonged use and vibration can cause the centers of the scope's optical system and the laser rangefinder's optical system to shift. Therefore, it is necessary to align and overlap the aiming red dot and the rangefinder's center to avoid affecting aiming and losing accuracy. Summary of the Invention

[0004] The purpose of this invention is to provide a linkage adjustment mechanism for a laser rangefinder red dot sight to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a linkage adjustment mechanism for a laser rangefinder red dot sight, including a mount and an inner tube. A red dot sight is installed inside the inner tube and used to generate an aiming red dot. An objective lens and an eyepiece are respectively located at the front and rear ends of the inner tube on the mount. The linkage adjustment mechanism of the laser rangefinder red dot sight further includes:

[0006] A first adjustment mechanism and a second adjustment mechanism are disposed on the lens mount and near the objective lens end. The inner ends of the first adjustment mechanism and the second adjustment mechanism extend into the lens mount and abut against the outside of the inner tube. They are used to adjust the movement of the inner tube radially, thereby adjusting the aiming red dot to achieve horizontal and vertical movement.

[0007] A laser ranging module is disposed on the outside of the inner tube and is elastically connected to the inner tube. The laser ranging module can emit laser and generate a ranging center and measure distance. The laser ranging module includes a third adjustment mechanism and a fourth adjustment mechanism. The third adjustment mechanism is used to adjust the horizontal movement of the ranging center, and the fourth adjustment mechanism is used to adjust the vertical movement of the ranging center, so that the ranging center is aligned and overlapped with the aiming red dot.

[0008] A further embodiment of the present invention is that the first adjustment mechanism and the laser ranging module are located on the same side of the lens mount, the second adjustment mechanism is located on the top of the lens mount, the lens mount has an adjustment hole, the first adjustment mechanism includes a first adjustment screw, the second adjustment mechanism includes a second adjustment screw, both the first adjustment screw and the second adjustment screw are threaded into the adjustment hole, the outer side of the inner tube forms an arc-shaped mating surface, the inner ends of the first adjustment screw and the second adjustment screw slide in contact with the mating surface, and the end of the inner tube near the eyepiece is fixed to the lens mount by a pressure ring.

[0009] A further embodiment of the present invention includes: the laser ranging module further comprising:

[0010] Module fixing plate, on which the laser ranging module is fixed;

[0011] The base has elastic deformation capability, the module fixing plate is adjustablely connected to the side of the base, and the base is fixed to the side of the mirror base;

[0012] The fourth adjustment mechanism is connected between the module fixing plate and the base, and the vertical displacement of the distance measuring center can be adjusted through the fourth adjustment mechanism.

[0013] The base has an open end, which can open and close under external force. The third adjustment mechanism is adjustable on the open end of the base, and the horizontal displacement of the ranging center can be adjusted through the third adjustment mechanism.

[0014] A spring-back mechanism is connected between the module fixing plate and the open end of the base, and the spring-back mechanism provides a spring-back force for the opening and closing action of the open end of the base.

[0015] A further embodiment of the present invention is that the module fixing plate includes an L-shaped frame and two protrusions located at both ends. The laser ranging module is fixed on the L-shaped frame, and the transmitting and receiving ends of the laser ranging module are located on one side of the L-shaped frame. The two protrusions are spaced apart. The protrusions are located on the upper part of the open end of the base. One of the protrusions and the base are connected by a rotation about an axis. The fourth adjustment mechanism is located between the other protrusion and the base. The third adjustment mechanism is located on the open end of the base and between the two protrusions. The spring mechanism is symmetrical on both sides of the third adjustment mechanism.

[0016] A further embodiment of the present invention is that a first through hole is provided on the protrusion, and a rotating shaft stud is inserted through the first through hole. The rotating shaft stud penetrates the base and is rotatably connected to the base, and the rotating shaft stud forms the axis of rotation between the module fixing plate and the base.

[0017] A further embodiment of the present invention is that, unlike the second through hole which is located on another protrusion, the base has an elongated groove opposite to the second through hole. The fourth adjustment mechanism includes an eccentric stud, which is built into and threadedly connected to the second through hole. An eccentric column is provided at the eccentric position at the bottom of the eccentric stud. The eccentric column passes through the elongated groove and slides with the elongated groove. By rotating the eccentric stud, the eccentric column is forced to slide at different positions in the elongated groove, thereby changing the vertical displacement of the ranging center with the axis of rotation of the stud as the axis of rotation.

[0018] A further embodiment of the present invention is that the open end of the base is provided with corresponding upper and lower positioning grooves, the positioning grooves are located between two protrusions, the third adjustment mechanism includes an adjusting sleeve and an adjusting screw, the adjusting screw is fixedly engaged in the positioning groove, the adjusting sleeve and the adjusting screw are threadedly connected, the bottom end of the adjusting sleeve is attached to the base, and the horizontal displacement of the ranging center is adjusted by twisting the adjusting sleeve to change the opening angle of the open end of the base.

[0019] A further embodiment of the present invention is that the protrusion has a third through hole symmetrically opened on both sides of the adjusting screw. The spring-back mechanism includes a spring sleeve and a spring. The spring sleeve is built into and threadedly connected in the third through hole. One end of the spring is fixed to the open end of the base and penetrates the base. The other end of the spring is built into the spring sleeve.

[0020] A further embodiment of the present invention is that the base is an elastic U-shaped metal plate, and the base is provided with fixing holes.

[0021] The beneficial effects of this invention are:

[0022] The horizontal displacement of the aiming red dot is adjusted by the first adjustment mechanism, and the vertical displacement of the aiming red dot is adjusted by the second adjustment mechanism. At the same time, the horizontal and vertical displacements of the ranging center are adjusted by the laser ranging module. The linkage between these mechanisms enables the aiming red dot and the ranging center to achieve high-precision centering and overlap. The module fixing plate is movably connected to the base. A rotating shaft stud is rotatably connected between the module fixing plate and the base. The axis of the rotating shaft stud is the origin of rotation. The adjustment of the fourth adjustment mechanism changes the vertical displacement of the ranging center. The opening angle of the open end of the base can be changed by the third adjustment mechanism, thereby changing the horizontal displacement of the ranging center. The module fixing plate and the base are provided with a spring-loaded mechanism to provide the spring force for vertical angle adjustment, so that centering adjustment can be quickly achieved in both horizontal and vertical directions. The adjustment process is simple and reliable.

[0023] The contact points between the mating surfaces of the inner tube and the first and second adjusting screws can be automatically dispersed by sliding fine-tuning, thereby reducing displacement deviation caused by vibration and improving the overall anti-shake capability of the scope. In addition, the sliding contact between the arc-shaped surface of the inner tube and the first and second adjusting screws can absorb the local stress caused by the tilting of the inner tube due to gravity, reducing mechanical jamming.

[0024] The elastic properties of the base and the rebound mechanism can work together to produce a composite damping effect. The elastic deformation of the open end of the base can also absorb high-frequency vibration energy. Not only do they each generate displacement of the horizontal distance measuring center, but the compression spring on the rebound mechanism also suppresses low-frequency shaking through symmetrical compression and release, forming a wide-band anti-interference effect. The symmetrical compression and release offsets residual stress, maintains the stability of the distance measuring center during dynamic adjustment, and also reduces the deformation of the base.

[0025] The first, second, third, and fourth adjustment mechanisms work together to form a closed-loop adjustment feedback system. If the target red dot shifts to the right due to vibration, the third adjustment mechanism can compensate for the distance measurement center to the left, while the fourth adjustment mechanism corrects the pitch angle deviation, achieving multi-dimensional dynamic compensation with bidirectional dynamic balance. It also enables multi-path coordination. If one adjustment mechanism fails due to mechanical wear or jamming, other mechanisms can compensate for the partial shift through linkage. For example, if the vertical adjustment of the fourth adjustment mechanism fails, the first adjustment mechanism can indirectly correct the inner tube pitch angle through the sliding of the arc-shaped mating surface, combined with the horizontal adjustment of the third adjustment mechanism to achieve approximate centering, improving system robustness and reducing the risk of overall failure due to a single component malfunction.

Additionally, features described with reference to certain examples may be combined in other examples.

[0042] Example 1: As Figure 1 and Figure 2 This embodiment provides a linkage adjustment mechanism for a laser rangefinder red dot sight, including a mount 7 and an inner tube 8. The inner tube 8 houses the red dot sight and is used to generate the aiming red dot. The mount 7 is provided with an objective lens 80 and an eyepiece 81 located at the front and rear ends of the inner tube 8, respectively. The linkage adjustment mechanism of the laser rangefinder red dot sight further includes:

[0043] A first adjustment mechanism and a second adjustment mechanism are provided on the lens mount 7 and near one end of the objective lens 80. The inner ends of the first adjustment mechanism and the second adjustment mechanism extend into the lens mount 7 and abut against the outside of the inner tube 8. They are used to adjust the movement of the inner tube 8 radially, thereby adjusting the aiming red dot to achieve horizontal and vertical movement.

[0044] A laser ranging module 1 is disposed outside the inner tube 8 and is elastically and adjustablely connected to the inner tube 8. The laser ranging module 1 can emit laser and generate a ranging center and measure distance. The laser ranging module 1 includes a third adjustment mechanism 5 and a fourth adjustment mechanism 4. The third adjustment mechanism 5 is used to adjust the horizontal movement of the ranging center, and the fourth adjustment mechanism 4 is used to adjust the vertical movement of the ranging center, so that the ranging center is aligned and overlapped with the aiming red dot.

[0045] Furthermore, in this invention, the first adjustment mechanism and the laser ranging module 1 are located on the same side of the lens base 7, and the second adjustment mechanism is located on the top of the lens base 7. An adjustment hole 70 is provided on the lens base 7. The first adjustment mechanism includes a first adjustment screw 9, and the second adjustment mechanism includes a second adjustment screw 10. Both the first adjustment screw 9 and the second adjustment screw 10 are threaded into the adjustment hole 70. An arc-shaped mating surface 82 is formed on the outside of the inner tube 8. The inner ends of the first adjustment screw 9 and the second adjustment screw 10 slide in contact with the mating surface 82. The end of the inner tube 8 near the eyepiece 81 is fixed to the lens base 7 by a pressure ring 11. By rotating the first adjustment screw 9 and the second adjustment screw 10, the mating surface 82 can be pushed to force the inner tube 8 to produce small horizontal and vertical displacements, thereby achieving horizontal and vertical displacement for aiming at the red dot. Furthermore, the contact points between the mating surface 82 on the outside of the inner tube 8 and the first adjusting screw 9 and the second adjusting screw 10 can be used to automatically disperse the impact force through sliding fine adjustment, thereby reducing the displacement deviation caused by vibration and improving the overall anti-shake capability of the scope. In addition, the sliding contact between the arc-shaped surface of the inner tube 8 and the first adjusting screw 9 and the second adjusting screw 10 can absorb the local stress caused by the tilt of the inner tube 8 due to gravity, reducing mechanical jamming.

[0046] Laser ranging module 1 is an existing laser emitting and laser receiving module, which will not be described in detail in this embodiment. Laser ranging module 1 also includes:

[0047] Module fixing plate 2, the laser ranging module 1 is fixed on the module fixing plate 2, the module fixing plate 2 provides support and fixation for the laser ranging module 1;

[0048] The base 3 has elastic deformation capability. The module fixing plate 2 is adjustablely connected to the base 3. The base 3 is fixed to the side of the mirror base 7. The module fixing plate 2 can be rotated on the side of the base 3 to achieve vertical adjustment. According to the elastic performance of the base 3, the opening and closing angle of one end of the base 3 can be changed to achieve horizontal displacement adjustment of the distance measuring center.

[0049] The fourth adjustment mechanism 4 is connected between the module fixing plate 2 and the base 3. The vertical displacement of the ranging center can be adjusted through the fourth adjustment mechanism 4.

[0050] The third adjustment mechanism 5 has an open end 30 on the base 3. The open end 30 can open and close under external force. The third adjustment mechanism 5 is adjustable on the open end 30 of the base 3. The horizontal displacement of the ranging center can be adjusted through the third adjustment mechanism 5. Therefore, when it is necessary to adjust the center of the ranging center, it can be gradually adjusted in both horizontal and vertical directions until it overlaps with the aiming red dot. The overall structure is simple and the adjustment is quick.

[0051] The spring mechanism 6 is connected between the module fixing plate 2 and the open end 30 of the base 3. The spring mechanism 6 provides spring force for the opening and closing action of the open end 30 of the base 3. When the vertical height of the laser ranging module 1 is increased, the spring mechanism 6 plays the role of compression spring force. When the height of the laser ranging module 1 is decreased, the elastic potential energy compressed by the spring mechanism 6 is released, increasing the spring force of reset. Therefore, the adjustment in both vertical and horizontal directions is realized through the fourth adjustment mechanism 4 and the third adjustment mechanism 5, thereby adjusting the center alignment of the ranging module 1.

[0052] In this embodiment, a further implementation is that the fourth adjustment mechanism 4, the third adjustment mechanism 5, and the rebound mechanism 6 are all on the same side and away from the transmitting and receiving end of the laser ranging module 1. The open end 30 of the base 3 is away from the transmitting and receiving end of the laser ranging module 1. The fourth adjustment mechanism 4 and the third adjustment mechanism 5 are both located on the same side, and control and adjustment are performed on the same side. The layout is reasonable and improves the efficiency of coordinated control.

[0053] In this embodiment, a further implementation is that the module fixing plate 2 includes an L-shaped frame 20 and two protrusions 21 located at both ends. The laser ranging module 1 is fixed on the L-shaped frame 20, and the transmitting and receiving ends of the laser ranging module 1 are located on one side of the L-shaped frame 20. The two protrusions 21 are spaced apart, and the protrusions 21 are located on the upper part of the open end 30 of the base 3. One of the protrusions 21 and the base 3 are connected by a rotation about an axis. The fourth adjustment mechanism 4 is located between the other protrusion 21 and the side of the base 3. The third adjustment mechanism 5 is set on the open end 30 of the base 3 and located between the two protrusions 21. The spring mechanism 6 is symmetrical on both sides of the third adjustment mechanism 5, that is, the center of rotation is formed between one of the protrusions 21 and the base 3. The fourth adjustment mechanism 4 is set on the other protrusion 21. Therefore, during adjustment, by adjusting the fourth adjustment mechanism 4, the module fixing plate 2 rotates around the rotation center on the other protrusion 21, and the laser ranging module 1 can swing. Thus, the vertical displacement of the ranging center can be adjusted in the vertical direction.

[0054] In this embodiment, a further implementation is that a first through hole 210 is provided on the protrusion 21, and a rotating shaft stud 211 is inserted into the first through hole 210. The rotating shaft stud 211 penetrates the base 3 and is rotatably connected to the base 3. The rotating shaft stud 211 forms the axis of rotation between the module fixing plate 2 and the base 3. The rotating shaft stud 211 not only accurately aligns the module fixing plate 2 and the base 3, but also provides the center of rotation for the module fixing plate 2 and the base 3. Designing the rotating shaft stud 211 on one of the protrusions 21 instead of designing it on the centerline of the module fixing plate 2 can avoid the position of the third adjustment mechanism 5 and achieve the minimum offset when adjusting at the same angle.

[0055] In this embodiment, a further implementation is that, unlike the second through hole 212 opened on the other protrusion 21 where the first through hole 210 is located, the base 3 has an elongated groove 31 opposite to the second through hole 212. The fourth adjustment mechanism 4 includes an eccentric stud 40, which is built into and threadedly connected to the second through hole 212. An eccentric post 400 is provided at the eccentric position of the bottom of the eccentric stud 40. The eccentric post 400 passes through the elongated groove 31 and slides with the elongated groove 31. By rotating the eccentric stud 40, the eccentric post 400 is forced to slide in the elongated groove 31. The rotation angle of the laser ranging module 1 on the side of the base 3 can be changed by using the axis of the rotating shaft stud 211 as the rotation axis. During adjustment, a flathead screwdriver can be used to twist the eccentric stud 40. Since the eccentric stud 400 is eccentrically set, it is forced to rotate along the axis of the rotating shaft stud 211 through the sliding cooperation with the elongated groove 31, so as to achieve vertical adjustment. The setting of the eccentric stud 40 is not only simple in structure, but also requires the use of a screwdriver to adjust, avoiding the easy accidental contact caused by adjusting without the help of tools, and improving the safety of adjustment.

[0056] Example 2: A linkage adjustment mechanism for a laser rangefinder red dot sight includes a mount 7 and an inner tube 8. A red dot sight is installed inside the inner tube 8 and used to generate an aiming red dot. The mount 7 is provided with an objective lens 80 and an eyepiece 81 located at the front and rear ends of the inner tube 8, respectively. The linkage adjustment mechanism of the laser rangefinder red dot sight further includes:

[0057] A first adjustment mechanism and a second adjustment mechanism are provided on the lens mount 7 and near one end of the objective lens 80. The inner ends of the first adjustment mechanism and the second adjustment mechanism extend into the lens mount 7 and abut against the outside of the inner tube 8. They are used to adjust the movement of the inner tube 8 radially, thereby adjusting the aiming red dot to achieve horizontal and vertical movement.

[0058] A laser ranging module 1 is disposed on the side of the lens mount 7. The laser ranging module 1 can emit laser and generate a ranging center and measure distance. The laser ranging module 1 includes a third adjustment mechanism 5 and a fourth adjustment mechanism 4. The third adjustment mechanism 5 is used to adjust the horizontal movement of the ranging center, and the fourth adjustment mechanism 4 is used to adjust the vertical movement of the ranging center so that the ranging center is aligned and overlapped with the aiming red dot.

[0059] Furthermore, in this invention, the first adjustment mechanism and the laser ranging module 1 are located on the same side of the lens base 7, and the second adjustment mechanism is located on the top of the lens base 7. An adjustment hole 70 is provided on the lens base 7. The first adjustment mechanism includes a first adjustment screw 9, and the second adjustment mechanism includes a second adjustment screw 10. Both the first adjustment screw 9 and the second adjustment screw 10 are threaded into the adjustment hole 70. An arc-shaped mating surface 82 is formed on the outside of the inner tube 8. A micro display screen mounting base 84 is also fixed in the inner tube 8, and a micro display screen 83 is installed on the micro display screen mounting base 84. The inner ends of the first adjustment screw 9 and the second adjustment screw 10 slide in contact with the mating surface 82. The end of the inner tube 8 near the eyepiece 81 is fixed to the lens base 7 by a pressure ring. By rotating the first adjustment screw 9 and the second adjustment screw 10, the mating surface 82 can be pushed to force the inner tube 8 to produce small horizontal and vertical displacements, thereby achieving horizontal and vertical displacement for aiming at the red dot. Furthermore, the contact points between the mating surface 82 on the outside of the inner tube 8 and the first adjusting screw 9 and the second adjusting screw 10 can be used to automatically disperse the impact force through sliding fine adjustment, thereby reducing the displacement deviation caused by vibration and improving the overall anti-shake capability of the scope. In addition, the sliding contact between the arc-shaped surface of the inner tube 8 and the first adjusting screw 9 and the second adjusting screw 10 can absorb the local stress caused by the tilt of the inner tube 8 due to gravity, reducing mechanical jamming.

[0060] Laser ranging module 1 is an existing laser emitting and laser receiving module, which will not be described in detail in this embodiment. Laser ranging module 1 also includes:

[0061] Module fixing plate 2, the laser ranging module 1 is fixed on the module fixing plate 2, the module fixing plate 2 provides support and fixation for the laser ranging module 1;

[0062] The base 3 has elastic deformation capability. The module fixing plate 2 is adjustablely connected to the side of the base 3. The base 3 is fixed to the side of the mirror base 7. The module fixing plate 2 can be rotated on the side of the base 3 to achieve vertical adjustment. According to the elastic performance of the base 3, the opening and closing angle of one end of the base 3 can be changed to achieve horizontal displacement adjustment of the distance measuring center.

[0063] The fourth adjustment mechanism 4 is connected between the module fixing plate 2 and the base 3. The vertical displacement of the ranging center can be adjusted through the fourth adjustment mechanism 4.

[0064] The third adjustment mechanism 5 has an open end 30 on the base 3. The open end 30 can open and close under external force. The third adjustment mechanism 5 is adjustable on the open end 30 of the base 3. The horizontal displacement of the ranging center can be adjusted through the third adjustment mechanism 5. Therefore, when it is necessary to adjust the center of the ranging center, it can be gradually adjusted in both horizontal and vertical directions until it overlaps with the aiming red dot. The overall structure is simple and the adjustment is quick.

[0065] The spring mechanism 6 is connected between the module fixing plate 2 and the open end 30 of the base 3. The spring mechanism 6 provides spring force for the opening and closing action of the open end 30 of the base 3. When the vertical height of the laser ranging module 1 is increased, the spring mechanism 6 plays the role of compression spring force. When the height of the laser ranging module 1 is decreased, the elastic potential energy compressed by the spring mechanism 6 is released, increasing the spring force of reset. Therefore, the vertical and horizontal adjustments are realized through the fourth adjustment mechanism 4 and the third adjustment mechanism 5, thereby adjusting the overlap between the ranging center of the laser ranging module 1 and the aiming red dot.

[0066] In this embodiment, a further implementation is that the fourth adjustment mechanism 4, the third adjustment mechanism 5, and the rebound mechanism 6 are all on the same side and away from the transmitting and receiving end of the laser ranging module 1. The open end 30 of the base 3 is away from the transmitting and receiving end of the laser ranging module 1. The fourth adjustment mechanism 4 and the third adjustment mechanism 5 are both located on the same side, and control and adjustment are performed on the same side. The layout is reasonable and improves the efficiency of coordinated control.

[0067] In this embodiment, a further implementation is that the module fixing plate 2 includes an L-shaped frame 20 and two protrusions 21 located at both ends. The laser ranging module 1 is fixed on the L-shaped frame 20, and the transmitting and receiving ends of the laser ranging module 1 are located on one side of the L-shaped frame 20. The two protrusions 21 are spaced apart, and the protrusions 21 are located on the upper part of the open end 30 of the base 3. One of the protrusions 21 and the base 3 are connected by a rotation about an axis. The fourth adjustment mechanism 4 is located between the other protrusion 21 and the side of the base 3. The third adjustment mechanism 5 is set on the open end 30 of the base 3 and located between the two protrusions 21. The spring mechanism 6 is symmetrical on both sides of the third adjustment mechanism 5, that is, the center of rotation is formed between one of the protrusions 21 and the base 3. The fourth adjustment mechanism 4 is set on the other protrusion 21. Therefore, during adjustment, by adjusting the fourth adjustment mechanism 4, the module fixing plate 2 rotates around the rotation center on the other protrusion 21, and the laser ranging module 1 can swing. Thus, the vertical displacement of the ranging center can be adjusted in the vertical direction.

[0068] In this embodiment, a further implementation is that a first through hole 210 is provided on the protrusion 21, and a rotating shaft stud 211 is inserted into the first through hole 210. The rotating shaft stud 211 penetrates the base 3 and is rotatably connected to the base 3. The rotating shaft stud 211 forms the axis of rotation between the module fixing plate 2 and the base 3. The rotating shaft stud 211 not only accurately aligns the module fixing plate 2 and the base 3, but also provides the center of rotation for the module fixing plate 2 and the base 3. Designing the rotating shaft stud 211 on one of the protrusions 21 instead of designing it on the centerline of the module fixing plate 2 can avoid the position of the third adjustment mechanism 5 and achieve the minimum offset when adjusting at the same angle. Furthermore, while the module fixing plate 2 rotates slightly around the rotating shaft stud 211, the open end 30 of the base 3 compensates for the lateral offset through elastic deformation, which can also achieve bidirectional dynamic correction in both horizontal and vertical directions.

[0069] In this embodiment, a further implementation is that, unlike the second through hole 212 opened on the other protrusion 21 where the first through hole 210 is located, the base 3 has an elongated groove 31 opposite to the second through hole 212. The fourth adjustment mechanism 4 includes an eccentric stud 40, which is built into and threadedly connected to the second through hole 212. An eccentric post 400 is provided at the eccentric position of the bottom of the eccentric stud 40. The eccentric post 400 passes through the elongated groove 31 and slides with the elongated groove 31. By rotating the eccentric stud 40, the eccentric post 400 is forced to slide in the elongated groove 31. The rotation angle of the laser ranging module 1 on the side of the base 3 can be changed by using the axis of the rotating shaft stud 211 as the rotation axis. During adjustment, a flathead screwdriver can be used to twist the eccentric stud 40. Since the eccentric stud 400 is eccentrically set, it is forced to rotate along the axis of the rotating shaft stud 211 through the sliding cooperation with the elongated groove 31, so as to achieve vertical adjustment. The setting of the eccentric stud 40 is not only simple in structure, but also requires the use of a screwdriver to adjust, avoiding the easy accidental contact caused by adjusting without the help of tools, and improving the safety of adjustment.

[0070] In this embodiment, further, such as Figure 9 and Figure 10The open end 30 of the base 3 has corresponding upper and lower positioning grooves 300, all of which are U-shaped grooves. The positioning grooves 300 are located between two protrusions 21. The third adjustment mechanism 5 includes an adjusting sleeve 50 and an adjusting screw 51. The adjusting screw 51 is fixedly engaged in the positioning groove 300. The adjusting sleeve 50 and the adjusting screw 51 are threadedly connected. The bottom end of the adjusting sleeve 50 fits against the side of the base 3. By twisting the adjusting sleeve 50, the opening angle of the open end 30 of the base 3 is changed. In this embodiment, the third adjustment mechanism 5 is set in the middle position of the spring mechanism 6. Since the working principle of the third adjustment mechanism 5 is to force the open end 30 of the base 3 to produce elastic deformation, Therefore, during adjustment, a screwdriver is also needed to turn the adjusting sleeve 50. By adjusting the threaded engagement between the adjusting sleeve 50 and the adjusting stud, the force acting on the base 3 is centered at the open end 30 of the base 3, thus improving balance and preventing the side of the base 3 from wobbling during adjustment, thereby improving the accuracy of the adjustment centering. Twisting makes the width of the open end 30 of the base 3 smaller, at which point the spring mechanism 6 is in a compressed state, and the distance measuring center moves upward. Folding it over, when the width of the open end 30 of the base 3 increases, the spring mechanism 6 releases the spring force, and the distance measuring center moves to the right. Again, a screwdriver is needed for adjustment to avoid accidental activation that may occur when adjusting without tools, thus improving the safety of the adjustment.

[0071] In this embodiment, the base 3 is further described as an elastic U-shaped metal plate, and the base 3 is provided with fixing holes 32 for connecting and fixing to the firearm.

[0072] In addition, the protrusion 21 has a third through hole 213 symmetrically provided on both sides of the adjusting screw 51. The spring-rebound mechanism 6 includes a spring sleeve 60 and a spring 61. The spring sleeve 60 is built into and threadedly connected in the third through hole 213. One end of the spring 61 is fixed on the open end 30 of the base 3 and penetrates the base 3. The other end of the spring 61 is built into the spring sleeve 60. When the distance measuring center moves to the right, the spring 61 is in a compressed state. When the distance measuring center moves to the left, the spring 61 releases the rebound force.

[0073] Furthermore, the elastic characteristics of the base 3 and the rebound mechanism 6 can work together to produce a composite damping effect. The elastic deformation of the open end 30 of the base 3 can also absorb high-frequency vibration energy. Not only do they each generate displacement of the horizontal ranging center, but the compression spring 61 on the rebound mechanism 6 suppresses low-frequency shaking through symmetrical compression and release, forming a wide-band anti-interference effect. The symmetrical compression and release offsets residual stress, maintains the stability of the ranging center during dynamic adjustment, and also reduces the deformation of the base 3.

[0074] In this embodiment, the horizontal adjustment angle and the pitch adjustment angle of the laser ranging module 1 are between 0 and 3.2°, as shown in the attached figure. Of course, this adjustment range is only shown for reference, and the range can be flexibly designed and selected.

[0075] The first, second, third, and fourth adjustment mechanisms work together to form a closed-loop adjustment feedback system. If the target red dot shifts to the right due to vibration, the third adjustment mechanism 5 can compensate for the distance measurement center to the left, while the fourth adjustment mechanism 4 corrects the pitch angle deviation, achieving multi-dimensional dynamic compensation with bidirectional dynamic balance. It can also achieve multi-path coordination. If one adjustment mechanism fails due to mechanical wear or jamming, other mechanisms can compensate for part of the shift through linkage. For example, if the vertical adjustment of the fourth adjustment mechanism 4 fails, the first adjustment mechanism 9 can indirectly correct the inner tube pitch angle through the sliding of the arc-shaped mating surface 82, and combine it with the horizontal adjustment of the third adjustment mechanism 5 to achieve approximate centering, improving system robustness and reducing the risk of overall failure due to the failure of a single component.
