Its core function is to help users observe targets more clearly and improve the hit rate.

[0003] Since the optical system of the aiming scope and the optical system of the laser ranging module belong to two independent optical systems, it is necessary to adjust the optical center of the laser ranging module to be consistent with the optical center of the aiming scope. Therefore, there is an urgent need to propose an adjusting mechanism for the laser ranging module of the aiming scope to quickly perform centering adjustment of the optical center in multiple degrees of freedom.

Through the horizontal adjusting mechanism, the rotation angle of the laser ranging module on the upper end surface of the base can be adjusted. A vertical adjusting mechanism. The base has an open end, and the open end can generate an opening and closing action under an external force. The vertical adjusting mechanism is adjustably arranged on the open end of the base.

[0022] Embodiment 1: As Figure 1 and Figure 2 , this embodiment provides an adjustment mechanism for a telescopic sight laser ranging module, including a laser ranging module 1. The laser ranging module 1 is an existing module for emitting and receiving laser, which will not be elaborated in this embodiment. The adjustment mechanism for the telescopic sight laser ranging module further includes: A module fixing plate 2, on which the laser ranging module 1 is fixed, and the module fixing plate 2 provides support and fixation for the laser ranging module 1; A base 3, which has the ability of elastic deformation. The module fixing plate 2 is adjustably connected to the upper end surface of the base 3. The module fixing plate 2 can be rotationally adjusted on the upper end surface of the base 3 to achieve adjustment in the horizontal direction. According to the elastic performance of the base 3, the opening angle of one end of the base 3 is changed, so as to achieve the adjustment of the pitching angle of the optical center; A horizontal adjustment mechanism 4, which is connected between the module fixing plate 2 and the base 3. Through the horizontal adjustment mechanism 4, the rotation angle of the laser ranging module 1 on the upper end surface of the base 3 can be adjusted; The vertical adjustment mechanism 5, the base 3 has an open end 30, the open end 30 can generate an opening and closing action under an external force, the vertical adjustment mechanism 5 is adjustably arranged on the open end 30 of the base 3, and the inclination angle of the upper end surface of the base 3 can be adjusted through the vertical adjustment mechanism 5 to change the pitch angle of the laser ranging module 1. Therefore, when the optical center needs to be centered and adjusted, it is gradually adjusted to the center in both the horizontal and vertical directions, and the overall structure is simple and the adjustment is fast.

[0023] The elastic return mechanism 6 is connected between the module fixing plate 2 and the open end 30 of the base 3. The elastic return mechanism 6 provides a return force for the opening and closing action of the open end 30 of the base 3. When increasing the vertical height of the laser ranging module 1, the elastic return mechanism 6 plays a role in compressing the elastic force. When reducing the vertical height of the laser ranging module 1, the elastic potential energy compressed by the elastic return mechanism 6 is released to increase the return force of the reset. Therefore, the horizontal and vertical adjustments are realized through the horizontal adjustment mechanism 4 and the vertical adjustment mechanism 5, so as to adjust the centering of the optical center of the laser ranging module 1.

[0024] In this embodiment, a further implementation is that the horizontal adjustment mechanism 4, the vertical adjustment mechanism 5 and the elastic return 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 horizontal adjustment mechanism 4 and the vertical adjustment mechanism 5 are both arranged on the same side, and the control and adjustment are carried out on the same side, with a reasonable layout and improved efficiency of coordinated control.

[0025] In this embodiment, a further implementation is that the module fixing plate 2 includes L-shaped frames 20 at both ends and two convex blocks 21. The laser ranging module 1 is fixed on the L-shaped frame 20. The transmitting and receiving end of the laser ranging module 1 is on the side where the L-shaped frame 20 is located. The two convex blocks 21 are arranged at intervals. The convex blocks 21 are located above the open end 30 of the base 3. A rotation centered on the axis is constructed between one of the convex blocks 21 and the upper end surface of the base 3. The horizontal adjustment mechanism 4 is arranged between the other convex block 21 and the upper end surface of the base 3. The vertical adjustment mechanism 5 is arranged on the open end 30 of the base 3 and between the two convex blocks 21. The elastic return mechanism 6 is symmetrically arranged on both sides of the vertical adjustment mechanism 5, that is, with the center of rotation formed between one of the convex blocks 21 and the base 3 as the center, the horizontal adjustment mechanism 4 is arranged on the other convex block 21. Furthermore, when adjusting, by adjusting the horizontal adjustment mechanism 4, the module fixing plate 2 rotates around the rotation center on the other convex block 21, and the laser ranging module 1 can swing, so the position of the optical center can be adjusted in the horizontal direction.

[0026] In this embodiment, a further implementation scheme is that a first through hole 210 is formed in one of the bumps 21, and a rotating shaft stud 211 is inserted into the first through hole 210. The rotating shaft stud 211 penetrates the upper end surface of the base 3 and is rotatably connected to the base 3. The rotating shaft stud 211 constructs the axis of rotation between the module fixing plate 2 and the base 3. The rotating shaft stud 211 not only accurately positions 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. The rotating shaft stud 211 is designed on one of the bumps 21 instead of the middle line position of the module fixing plate 2. On the one hand, it can avoid the position of the vertical adjustment mechanism 5, and on the other hand, it can achieve the minimum offset amount during the same angle adjustment.

[0027] In this embodiment, a further implementation scheme is that a second through hole 212 is formed in the other bump 21 different from the first through hole 210. A long oval groove 31 is formed on the upper end surface of the base 3 opposite to the second through hole 212. The horizontal adjustment mechanism 4 includes an eccentric stud 40. The eccentric stud 40 is internally placed and threadedly connected in the second through hole 212. An eccentric column 400 is provided at the eccentric position at the bottom of the eccentric stud 40. The eccentric column 400 passes through the long oval groove 31 and is slidably matched with the long oval groove 31. By rotating the eccentric stud 40, the eccentric column 400 is forced to slide at different positions in the long oval groove 31. Taking the axis of the rotating shaft stud 211 as the axis of rotation, the rotation angle of the laser ranging module 1 on the upper end surface of the base 3 is changed. During adjustment, an Allen key can be used to twist the eccentric stud 40. Since the eccentric column 400 is eccentrically arranged, through the sliding fit with the long oval groove 31, the module fixing plate 2 is forced to rotate along the axis of the rotating shaft stud 211, realizing horizontal adjustment. The setting of the eccentric stud 40 not only has a simple structure, but also requires the use of a screwdriver to adjust, avoiding accidental touch that is likely to occur when adjustment does not require tools, and improving the safety protection of adjustment.

[0028] Embodiment 2: An adjustment mechanism for a telescopic sight laser ranging module, including a laser ranging module 1. The laser ranging module 1 is an existing module for emitting and receiving laser, which will not be elaborated in this embodiment. The adjustment mechanism for the telescopic sight laser ranging module further includes: A module fixing plate 2, on which the laser ranging module 1 is fixed. The module fixing plate 2 provides support and fixation for the laser ranging module 1; A base 3, which has the ability of elastic deformation. The module fixing plate 2 is adjustably connected to the upper end surface of the base 3. The module fixing plate 2 can be rotationally adjusted on the upper end surface of the base 3 to achieve horizontal adjustment. According to the elastic performance of the base 3, the opening and closing angle of one end of the base 3 is changed, so as to achieve the adjustment of the pitching angle of the optical center; A horizontal adjustment mechanism 4 is connected and arranged between the module fixing plate 2 and the base 3, and the rotation angle of the laser ranging module 1 on the upper end surface of the base 3 can be adjusted by the horizontal adjustment mechanism 4; The vertical adjustment mechanism 5 has an open end 30 on the base 3, and the open end 30 can generate an opening and closing action when subjected to an external force. The vertical adjustment mechanism 5 is adjustably arranged on the open end 30 of the base 3. The vertical adjustment mechanism 5 can adjust the inclination angle of the upper end surface of the base 3 to change the pitch angle of the laser ranging module 1. Therefore, when the optical center needs to be adjusted, it can be gradually adjusted to the center in the horizontal and vertical directions. The overall structure is simple and the adjustment is quick.

[0029] The rebound mechanism 6 is connected and arranged between the module fixing plate 2 and the open end 30 of the base 3. The rebound mechanism 6 provides a rebound 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 rebound mechanism 6 plays the role of compressing the elastic force. When the vertical height of the laser ranging module 1 is reduced, the elastic potential energy compressed by the rebound mechanism 6 is released, thereby improving the resetting rebound force. Therefore, the horizontal and vertical adjustments are realized by the horizontal adjustment mechanism 4 and the vertical adjustment mechanism 5, thereby adjusting the optical center alignment of the laser ranging module 1.

[0030] In this embodiment, a further implementation scheme is that the horizontal adjustment mechanism 4, the vertical adjustment mechanism 5 and the rebound mechanism 6 are all on the same side and away from the transmitting and receiving ends of the laser ranging module 1, the open end 30 of the base 3 is away from the transmitting and receiving ends of the laser ranging module 1, the horizontal adjustment mechanism 4 and the vertical adjustment mechanism 5 are both arranged on the same side, and control and adjustment are performed on the same side. The layout is reasonable to improve the efficiency of coordinated regulation.

[0031] In this embodiment, a further implementation scheme 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, the transmitting and receiving ends of the laser ranging module 1 are on the side where the L-shaped frame 20 is located, and the two protrusions 21 are arranged at intervals. The protrusions 21 are located at the upper part of the open end 30 of the base 3, and a rotation centered on the axis is constructed between one of the protrusions 21 and the upper end surface of the base 3, and the horizontal adjustment mechanism 4 is arranged between the other protrusion 21 and the upper end of the base 3. The vertical adjustment mechanism 5 is arranged on the open end 30 of the base 3 and between the two protrusions 21. The rebound mechanism 6 is symmetrical on both sides of the vertical adjustment mechanism 5, that is, a rotation center is formed between one of the protrusions 21 and the base 3. The horizontal adjustment mechanism 4 is arranged on the other protrusion 21. Then, when adjusting, the horizontal adjustment mechanism 4 is adjusted so that the module fixing plate 2 rotates around the rotation center on the other protrusion 21, and the laser ranging module 1 is able to swing, so the position of the optical center can be adjusted in the horizontal direction.

[0032] In this embodiment, a further implementation is that a first through hole 210 is formed in one of the bumps 21, and a rotating shaft stud 211 is inserted into the first through hole 210. The rotating shaft stud 211 penetrates through the upper end surface of the base 3 and is rotatably connected to the base 3. The rotating shaft stud 211 constructs the axis of rotation between the module fixing plate 2 and the base 3. The rotating shaft stud 211 not only accurately positions 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. The rotating shaft stud 211 is designed on one of the bumps 21 instead of the middle line position of the module fixing plate 2. On the one hand, it can avoid the position of the vertical adjustment mechanism 5, and on the other hand, it can achieve the minimum offset when adjusting at the same angle.

[0033] In this embodiment, a further implementation is to refer to Figure 5 and Figure 6 , on the other bump 21 different from the one where the first through hole 210 is located, a second through hole 212 is formed. A long oval groove 31 is formed on the upper end surface of the base 3 opposite to the second through hole 212. The horizontal adjustment mechanism 4 includes an eccentric stud 40. The eccentric stud 40 is internally disposed and threadedly connected in the second through hole 212. An eccentric post 400 is provided at the eccentric position at the bottom of the eccentric stud 40. The eccentric post 400 passes through the long oval groove 31 and is slidably engaged with the long oval groove 31. By rotating the eccentric stud 40, the eccentric post 400 is forced to slide at different positions in the long oval groove 31. With the axis of the rotating shaft stud 211 as the axis of rotation, the rotation angle of the laser ranging module 1 on the upper end surface of the base 3 is changed. During adjustment, an Allen key can be used to twist the eccentric stud 40. Since the eccentric post 400 is eccentrically arranged, through the sliding fit with the long oval groove 31, the module fixing plate 2 is forced to rotate along the axis of the rotating shaft stud 211, realizing horizontal adjustment. The setting of the eccentric stud 40 not only has a simple structure, but also requires the use of a screwdriver to adjust, avoiding accidental touch that is likely to occur when adjustment does not require tools, and improving the safety protection of adjustment.

[0034] In this embodiment, furthermore, as Figure 7 and Figure 8, a positioning groove 300 corresponding up and down is formed on the open end 30 of the base 3. The positioning grooves 300 are all U-shaped grooves. The positioning grooves 300 are located between two bumps 21. The vertical adjustment mechanism 5 includes an adjustment sleeve 50 and an adjustment screw 51. The adjustment screw 51 is fixedly clamped in the positioning groove 300. The adjustment sleeve 50 is in threaded fit with the adjustment screw 51. The bottom end of the adjustment sleeve 50 abuts against the upper end surface of the base 3. By twisting the adjustment sleeve 50, the opening and closing angle of the open end 30 of the base 3 is changed. In this embodiment, the vertical adjustment mechanism 5 is arranged at the middle position of the elastic return mechanism 6. Since the implementation principle of the vertical 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 twist the adjustment sleeve 50. Through the threaded fit of the adjustment sleeve 50 and the adjustment screw, the acting force on the base 3 is exactly in the middle at the position of the open end 30 of the base 3. Therefore, the balance is improved, so that the upper end surface of the base 3 will not swing left and right during adjustment, and the accuracy of adjustment centering is improved. When twisting makes the width of the open end 30 of the base 3 smaller, the elastic return mechanism 6 is in a compressed state at this time, and the optical center moves upward; when folding, when the width of the open end 30 of the base 3 becomes larger, the elastic return mechanism 6 releases the return spring force, and the optical center moves downward. Similarly, a screwdriver is needed to adjust, avoiding accidental touch easily caused by not using tools for adjustment, and improving the safety protection of adjustment.

[0035] In this embodiment, further, the base 3 is an elastic U-shaped metal plate, and a fixing hole 32 for connecting and fixing to a firearm is formed on the base 3.

[0036] In addition, third through holes 213 are symmetrically formed on both sides of the adjustment screw 51 on the bump 21. The elastic return mechanism 6 includes a compression spring sleeve 60 and a compression spring 61. The compression spring sleeve 60 is internally arranged and threadedly connected in the third through hole 213. One end of the compression spring 61 is fixed on the open end 30 of the base 3 and penetrates through the base 3. The other end of the compression spring 61 is internally arranged in the compression spring sleeve 60. When the optical center moves upward, the compression spring 61 is in a compressed state. When the optical center moves downward, the compression spring 61 releases the return spring force. In this embodiment, when the horizontal adjustment angle value and the pitch adjustment angle value of the laser ranging module 1 are between 0-3.2°, the drawings are correspondingly shown. Of course, the adjustment range of this interval is only shown here, and flexible design and selection can be made for this range.

Without 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 specific embodiments. The above specific embodiments are merely illustrative and not restrictive.
