The laser rangefinder module is fixed on the module fixing plate; the base has the ability of elastic deformation; a horizontal adjusting mechanism; a vertical adjusting mechanism; a rebound mechanism, which is connected between the open end of the module fixing plate and the base. The laser rangefinder module is fixed on the module fixing plate. A rotating shaft stud is rotatably connected between the module fixing plate and the base. Taking the axis of the rotating shaft stud as the rotation origin, the adjustment of the horizontal adjusting mechanism changes the horizontal deflection angle of the laser module on the upper end surface of the base.

Description

Technical Field

[0001] The present invention belongs to the technical field of aiming scopes, and particularly relates to an adjustment mechanism for a laser ranging module of an aiming scope. Background Art

[0002] An aiming scope (also known as an optical aiming scope, a sighting instrument, and a gun sight) is an optical instrument used to improve shooting accuracy and is usually mounted on firearms, crossbows, astronomical telescopes, stage lights, or other shooting weapons. Its core function is to help users observe the target 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 adjustment mechanism for the laser ranging module of the aiming scope to quickly perform centering adjustment of the optical center in multiple degrees of freedom. Summary of the Invention

[0004] The purpose of the present invention is to provide an adjustment mechanism for a laser ranging module of an aiming scope to solve the problems raised in the above background art.

[0005] In view of this, the present invention provides an adjustment mechanism for a laser ranging module of an aiming scope, including a laser ranging module, and further including:

[0006] A module fixing plate, on which the laser ranging module is fixed;

[0007] A base with the ability of elastic deformation. The module fixing plate is adjustably connected to the upper end surface of the base. The module fixing plate can be rotationally adjusted on the upper end surface of the base to achieve adjustment in the horizontal direction. According to the elastic performance of the base, the opening and closing angle of one end of the base is changed, so as to achieve adjustment of the pitching angle of the optical center;

[0008] A horizontal adjustment mechanism, which is connected between the module fixing plate and the base. Through the horizontal adjustment mechanism, the rotation angle of the laser ranging module on the upper end surface of the base can be adjusted;

[0009] A vertical adjustment mechanism. The base has an open end, and the open end can generate an opening and closing action under an external force. The vertical adjustment mechanism is adjustably arranged on the open end of the base. Through the vertical adjustment mechanism, the inclination angle of the upper end surface of the base can be adjusted to change the pitching angle of the laser ranging module. Therefore, when centering adjustment of the optical center is required, 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.

[0010] A rebound mechanism is connected and arranged between the module fixing plate and the open end of the base. The rebound mechanism provides a restoring force for the opening and closing action of the open end of the base. When increasing the vertical height of the laser ranging module, the rebound mechanism plays a role in compressing the elastic force. When reducing the vertical height of the laser ranging module, the elastic potential energy compressed by the rebound mechanism is released, improving the restoring force for resetting.

[0011] In the present invention, a further embodiment is that the horizontal adjustment mechanism, the vertical adjustment mechanism, and the rebound mechanism are all on the same side and away from the transmitting and receiving end of the laser ranging module. The open end of the base is away from the transmitting and receiving end of the laser ranging module. The horizontal adjustment mechanism and the vertical adjustment mechanism are both arranged on the same side, and control and adjustment are carried out on the same side, with a reasonable layout and improved efficiency of collaborative regulation.

[0012] In the present invention, a further embodiment is that the module fixing plate includes L-shaped frames at both ends and two convex blocks. The laser ranging module is fixed on the L-shaped frames. The transmitting and receiving end of the laser ranging module is on the side where the L-shaped frames are located. The two convex blocks are arranged at intervals. The convex blocks are located above the open end of the base. A rotation centered on the axis is constructed between one of the convex blocks and the upper end surface of the base. The horizontal adjustment mechanism is arranged between the other convex block and the upper end surface of the base. The vertical adjustment mechanism is arranged on the open end of the base and between the two convex blocks. The rebound mechanisms are symmetrically arranged on both sides of the vertical adjustment mechanism.

[0013] In the present invention, a further embodiment is that a first through hole is opened on one of the convex blocks. A rotating shaft stud is inserted into the first through hole. The rotating shaft stud penetrates the upper end surface of the base and is rotatably connected to the base. The axis of rotation between the module fixing plate and the base is constructed by the rotating shaft stud.

[0014] In the present invention, a further embodiment is that a second through hole is opened on the other convex block different from the first through hole. An oblong groove is opened on the upper end surface of the base opposite to the second through hole. The horizontal adjustment mechanism includes an eccentric stud. The eccentric stud is internally placed and threadedly connected in 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 oblong groove and is slidably matched with the oblong groove. By rotating the eccentric stud, the eccentric column is forced to slide at different positions in the oblong groove, and the rotation angle of the laser ranging module on the upper end surface of the base is changed with the axis of the rotating shaft stud as the axis of rotation.

[0015] In the present invention, a further embodiment is that positioning grooves corresponding up and down are provided at the open end of the base. The positioning grooves are located between two bumps. The vertical adjustment mechanism includes an adjustment sleeve and an adjustment screw rod. The adjustment screw rod is fixedly clamped in the positioning groove. The adjustment sleeve is in threaded connection with the adjustment screw rod. The bottom end of the adjustment sleeve abuts against the upper end surface of the base. By twisting the adjustment sleeve, the opening and closing angle of the open end of the base is changed.

[0016] In the present invention, a further embodiment is that third through holes are symmetrically provided on both sides of the adjustment screw rod on the bump. The return spring mechanism includes a compression spring sleeve and a compression spring. The compression spring sleeve is internally disposed and in threaded connection in the third through hole. One end of the compression spring is fixed on the open end of the base and penetrates through the base. The other end of the compression spring is internally disposed in the compression spring sleeve.

[0017] In the present invention, a further embodiment is that the base is an elastic U-shaped metal plate, and fixing holes are provided on the base.

[0018] In the present invention, a further embodiment is that the horizontal adjustment angle value and the pitch adjustment angle value of the laser ranging module are between 0 - 3.2°.

[0019] The beneficial effects of the present invention are as follows:

[0020] The laser ranging module is fixed on the module fixing plate. The module fixing plate is movably connected to the base through a rotating shaft stud. Taking the axis of the rotating shaft stud as the rotation origin, the adjustment of the horizontal adjustment mechanism changes the horizontal deflection angle of the laser module on the upper end surface of the base. The opening and closing angle of the open end of the base can be changed through the vertical adjustment mechanism, so as to change the inclination angle of the upper end surface of the base, forcing the pitch angle of the laser ranging module to be adjusted. A return spring force for vertical angle adjustment is provided between the module fixing plate and the base through the return spring mechanism, so that quick centering adjustment can be achieved in both the horizontal and vertical directions, and the adjustment process is simple and reliable.

[0034] 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 a module for emitting and receiving laser that is already available and will not be elaborated in this embodiment. The adjustment mechanism for the telescopic sight laser ranging module further includes:

[0035] 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.

[0036] 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 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.

[0037] The horizontal adjustment mechanism 4 is connected and arranged between the module fixing plate 2 and the base 3. The rotation angle of the laser ranging module 1 on the upper end surface of the base 3 can be adjusted through the horizontal adjustment mechanism 4;

[0038] 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. 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. The overall structure is simple and the adjustment is fast.

[0039] The spring-back mechanism 6 is connected and arranged between the module fixing plate 2 and the open end 30 of the base 3. The spring-back mechanism 6 provides a spring-back 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 spring-back 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 spring-back mechanism 6 is released to increase the spring-back 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 adjustment of the optical center of the laser ranging module 1.

[0040] In this embodiment, a further implementation scheme is that the horizontal adjustment mechanism 4, the vertical adjustment mechanism 5 and the spring-back 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. The control and adjustment are carried out on the same side, with a reasonable layout and improved efficiency of collaborative control.

[0041] In this embodiment, a further implementation is that the module fixing plate 2 includes L-shaped frames 20 located at both ends and two bumps 21. The laser distance measurement module 1 is fixed on the L-shaped frame 20. The transmitting and receiving end of the laser distance measurement module 1 is on the side where the L-shaped frame 20 is located. The two bumps 21 are arranged at intervals. The bumps 21 are located above the open end 30 of the base 3. A rotation centered on the axis is constructed between one of the bumps 21 and the upper end surface of the base 3. The horizontal adjustment mechanism 4 is arranged between the other bump 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 bumps 21. The spring-back 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 bumps 21 and the base 3 as the center, the horizontal adjustment mechanism 4 is arranged on the other bump 21. Furthermore, during adjustment, by adjusting the horizontal adjustment mechanism 4, the module fixing plate 2 rotates around the rotation center on the other bump 21, and the laser distance measurement module 1 swings, so that the position of the optical center can be adjusted in the horizontal direction.

[0042] In this embodiment, a further implementation is that a first through hole 210 is formed in one of the bumps 21. 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 at the midline 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.

[0043] In this embodiment, a further implementation scheme is that a second through hole 212 is provided on another bump 21 different from the first through hole 210. An oblong slot 31 is provided 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 an eccentric position at the bottom of the eccentric stud 40. The eccentric post 400 passes through the oblong slot 31 and is slidably engaged with the oblong slot 31. By rotating the eccentric stud 40, the eccentric post 400 is forced to slide at different positions in the oblong slot 31. Taking the axis of the rotary shaft stud 211 as the rotation axis, the rotation angle of the laser ranging module 1 on the upper end surface of the base 3 is changed. During adjustment, a flat head screwdriver can be used to twist the eccentric stud 40. Since the eccentric post 400 is eccentrically arranged, through the sliding fit with the oblong slot 31, the module fixing plate 2 is forced to rotate along the axis of the rotary 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.

[0044] Embodiment 2: An adjustment mechanism for a telescopic sight laser ranging module, including a laser ranging module 1. The laser ranging module 1 is a module for emitting and receiving laser that is already available and will not be elaborated in this embodiment. The adjustment mechanism for the telescopic sight laser ranging module further includes:

[0045] 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.

[0046] A base 3 with 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 and closing angle of one end of the base 3 is changed, thereby realizing the adjustment of the pitching angle of the optical center.

[0047] 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.

[0048] A 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 disposed on the open end 30 of the base 3. Through the vertical adjustment mechanism 5, the inclination angle of the upper end surface of the base 3 can be adjusted to change the pitching angle of the laser ranging module 1. Therefore, when the centering adjustment of the optical center is required, it is gradually adjusted to the center in both the horizontal and vertical directions. The overall structure is simple and the adjustment is fast.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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 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 of 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 midline 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.

[0053] In this embodiment, a further implementation is that, referring to Figure 5 and Figure 6 , a second through hole 212 is formed in another bump 21 different from the one where the first through hole 210 is located. An oblong slot 31 is formed in 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 an eccentric position at the bottom of the eccentric stud 40. The eccentric post 400 passes through the oblong slot 31 and is slidably engaged with the oblong slot 31. By rotating the eccentric stud 40, the eccentric post 400 is forced to slide at different positions in the oblong slot 31, and the rotation angle of the laser ranging module 1 on the upper end surface of the base 3 is changed with the axis of the rotating shaft stud 211 as the axis of rotation. During adjustment, a flat head screwdriver can be used to twist the eccentric stud 40. Since the eccentric post 400 is eccentrically arranged, the module fixing plate 2 is forced to rotate along the axis of the rotating shaft stud 211 through the sliding engagement with the oblong slot 31, 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.

[0054] In this embodiment, furthermore, as Figure 7 and Figure 8, a positioning groove 300 corresponding up and down is provided 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 adjusting sleeve 50 and an adjusting screw 51. The adjusting screw 51 is fixedly clamped in the positioning groove 300. The adjusting sleeve 50 is in threaded fit with the adjusting screw 51. The bottom end of the adjusting sleeve 50 abuts against the upper end surface 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 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 adjusting sleeve 50. Through the threaded fit of the adjusting sleeve 50 and the adjusting screw, the acting force on the base 3 is just 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.

[0055] 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 provided on the base 3.

[0056] In addition, third through holes 213 are symmetrically provided on both sides of the adjusting 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 provided 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 provided 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 corresponding drawings are shown. Of course, the adjustment range of this interval is only shown here, and flexible design and selection can be made for this range.

[0057] The embodiments of the present application have been described above in conjunction with the accompanying drawings. 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 rather than restrictive. Under the inspiration of the present application, those of ordinary skill in the art can also make many forms without departing from the purpose of the present application and the scope protected by the claims, and all of them belong to the protection scope of the present application.
