Description
Technical Field
[0001] The utility model relates to the technical field of aiming gun sights, in particular to a two-speed variable magnification prism gun sight. Background Art
[0002] At present, in order to take into account both close-range and long-range aiming and shooting, the conventional practice is to use a combination of a spot sight and a telescopic sight with a magnification, and install the telescopic sight on the eye side of the spot sight by flipping the bracket. When the telescopic sight is needed, it can be switched to the use position by flipping the bracket to perform long-range aiming or observation. When the telescopic sight is not needed, it can be switched to a position that does not hinder the shooter's aiming, that is, the storage position by flipping the bracket, and the spot sight can be used for close-range aiming. Although this combination can take into account the needs of aiming at both long and short distances, it is still inconvenient in installation and carrying because it is a combination of two sights. In response to this, our utility model patent CN215810563U discloses a sight that can switch magnification instantly, which realizes the need for aiming at both long and short distances by setting a variable magnification group that can switch between high and low magnification optical paths in the shell, and at the same time adjusts the prism group through the internal adjustment mechanism so as to adjust the trajectory and windage according to the surrounding shooting environment. However, as those skilled in the art know, the imaging quality of a scope is closely related to the coaxiality of the optical elements on the main optical path, and the internal adjustment mechanism adjusts the prism group on the main optical path. When the shooter makes ballistic or windage adjustments, the prism group will deviate from the optical axis under the action of the adjustment mechanism, which will affect the imaging quality of the scope to a certain extent, causing defects such as reduced resolution and blurred imaging, thereby affecting the shooter's aiming experience.

[0036] Gun scopes are often installed on firearms to improve aiming accuracy and reduce shooting difficulty. In this application, the meaning of "target side" is the end of the scope that is close to the shooter during actual operation, and the meaning of "object side" is the end of the scope that is close to the target during actual operation, that is, the end away from the shooter.
[0037] The present application discloses a two-speed variable magnification prism gun sight, please refer to Figures 1 to 5, the two-speed variable magnification prism gun sight includes a shell 1 and an external adjustment mechanism 2, the shell 1 and the external adjustment mechanism 2 are arranged in upper and lower layers, the shell 1 is provided with a main optical path 11 and an objective lens group 3, a prism group 4 and an eyepiece group 5 arranged in sequence from the object side to the eye side along the main optical path 11, the objective lens group 3 includes a variable magnification group 31, the external adjustment mechanism 2 includes a bracket seat 8 and a windage adjustment component 6 and a ballistic adjustment component 7 arranged on the bracket seat 8, the windage adjustment component 6 and the ballistic adjustment component 7 are both connected to the shell 1, when the windage adjustment is performed, the windage adjustment component 6 drives the shell 1 to swing left and right around the ballistic adjustment component 7, when the ballistic adjustment is performed, the ballistic adjustment component 7 drives the shell 1 to swing up and down around the windage adjustment component 6. During the swinging of the housing 1 , the optical elements arranged along the main optical path 11 are relatively still and always maintain the original coaxiality, thereby ensuring the imaging quality of the sight and avoiding defects such as reduced resolution and blurred imaging of the sight, which affect the shooter's aiming experience.
[0038] Further, referring to Figures 1, 4 and 5, the windage adjustment component 6 also includes a first adjustment shaft 62, which passes through the shell 1 and the bracket seat 8 around its own axis through threaded cooperation, and the two ends of the first adjustment shaft 62 are respectively connected to the two sides of the shell 1, and the trajectory adjustment component 7 includes a second connecting column 75, one end of the second connecting column 75 is connected to the bracket seat 8, and a rack sleeve 73 is provided along the axial direction of the second connecting column 75, and the rack sleeve 73 is rotatably connected to the shell 1 through threaded cooperation, and the other end of the second connecting column 75 is connected to the fourth limit member 76, and the rack sleeve 73 is fixedly connected to the second adjustment hand wheel 71. In one embodiment, the bracket seat 8 is provided with an internal thread that cooperates with the first adjustment shaft 62 thread. The first adjustment shaft 62 is rotated to cooperate with the internal thread set in the bracket seat 8. Since the bracket seat 8 is fixed on the guide rail of the firearm and is in a stationary state relative to the guide rail, the first adjustment shaft 62 rotates around its own axis and drives the housing 1 to swing left and right around the trajectory adjustment component 7; the housing 1 is provided with an internal thread that cooperates with the rack sleeve 73. Since the moving range of the rack sleeve 73 is limited, when the rack sleeve 73 is rotated, the rack sleeve 73 is in a state of self-rotation. Therefore, during the process of the rack sleeve 73 cooperating with the housing 1, the housing swings up and down around the windage adjustment component.
[0039] In order to ensure that the above-mentioned rifle scope maintains a high degree of stability during use, please refer to Figure 1. Figure 4, Figure 5, Figure 10, in one embodiment, the bracket seat 8 is provided with a first accommodating cavity 81, the first accommodating cavity 81 is provided with a first through hole 841, the first accommodating cavity 81 is embedded with a first connecting column 64, the first connecting column 64 is provided with a first threaded through hole 65, the first adjusting shaft 62 is provided with an external thread matching with the first threaded through hole 65, the first adjusting shaft 62 passes through the first through hole 841 and is threadedly matched with the first threaded through hole 65, one end of the first adjusting shaft 62 is provided with a first adjusting hand wheel 61, and the other end of the first adjusting shaft 62 is connected to the first limit member 66. When the first adjusting hand wheel 61 is rotated, the first adjusting hand wheel 61 will drive the first adjusting shaft 62 to engage with the first threaded through hole 65 by threading. Because both ends of the first adjusting shaft 62 are connected to the housing 1, and the bracket seat 8 is fixed on the guide rail of the firearm, the first connecting column 64 is stationary relative to the bracket 8. Therefore, during the process of the first adjusting shaft 62 and the first threaded through hole 65 being threadedly engaged, the first adjusting shaft 62 will move left and right along the direction of the threaded engagement and drive the housing 1. Because the housing 1 is connected to the connecting structure, the housing 1 will swing left and right around the connecting structure accordingly, and the optical element arranged inside the housing 1 will move synchronously with the housing 1, thereby achieving the purpose of windage adjustment. Further, the first limit member 66 abuts against the shell 1, and one end of the first adjustment shaft 62 is provided with a threaded placement hole. The first limit member 66 includes a nut and a screw, and the screw passes through the nut and is connected to the threaded placement hole, so that one end of the first adjustment shaft 62 is connected to one side of the shell 1, and the other end of the first adjustment shaft 62 is provided with a boss, and the bottom surface of the boss abuts against the surface of the shell 1, so rotating the first adjustment hand wheel 61 drives the first adjustment shaft 62 to engage with the first connecting column 64 by thread, and the first adjustment shaft 62 will pull or push the shell 1 to swing left and right around the trajectory adjustment component 7 relative to the bracket seat 8 to adjust the windage of the gun aiming. In this embodiment, the connection method between the first limit member and the first adjustment shaft 62 and the shell 1 is not limited, and a detachable connection, a fixed connection, etc. can be adopted.
[0040] Please refer to Figures 1, 5 and 10. In one embodiment, the first connecting column 64 includes an upper column 641 and a lower column 642. The bracket seat 8 is provided with a receiving hole 85. The first receiving cavity 81 is provided with a second through hole 842. The receiving hole 85 is connected with the second through hole 842. The first threaded through hole 65 is provided on the upper column 641. The lower column 642 passes through the second through hole 842 to enter the receiving hole 85 and is connected with the second limiter 67. The diameter of the receiving hole 85 is larger than the diameter of the second through hole 842 to further limit the position of the first connecting column 64 to prevent the first connecting column 64 from moving during the threaded engagement with the first adjustment shaft 62 during the rotation process, resulting in adjustment deviation. In this embodiment, the second limiting member 67 can be a pad made of the same material as the bracket seat 8, and the pad is detachably and fixedly connected to one end of the lower column 642. Since the first connecting column 64 is limited, when the first adjustment shaft 62 is rotated, the first connecting column 64 will not move easily, thereby improving the adjustment efficiency.
[0041] Please refer to Figures 1 and 5. In one embodiment, in order to further improve the adjustment efficiency and improve the user experience, the windage adjustment component 6 also includes a first feel enhancement device, which includes a first placement hole 68 arranged on the side wall of the first adjustment shaft 62, and a retractable second protrusion 69 is arranged in the first placement hole 68. The first feel enhancement device also includes a first connecting ring 63, which is fixedly arranged on one side of the shell 1. The first adjustment shaft 62 passes through the first connecting ring 63 around its own axis and abuts against the first connecting ring 63. The side wall of the first connecting ring 63 is provided with peripheral teeth and grooves, and the second protrusion 69 abuts against the peripheral teeth and grooves. When the external force drives the first adjustment shaft 62 to rotate, the second protrusion 69 rotates synchronously and generates a concave and convex feeling. The retractable second protrusion 69 includes a spring and a tapered pin, one end of the spring is connected to the bottom surface of the first placement hole 68, and the other end is connected to the tapered pin, and the other end of the tapered pin abuts against the peripheral tooth groove. When the external force drives the first adjustment shaft 62 to rotate, the second protrusion 69 rotates synchronously, and at the same time generates a concave and convex feeling and a "tick-tick" sound, so as to facilitate the user to record and calculate the degree of adjustment of the shell 1, thereby obtaining more accurate wind deviation compensation, and the generated "tick-tick" further improves the user's adjustment experience.
[0042] Please refer to FIG. 1 . In one embodiment, the trajectory adjustment assembly 7 further includes a second connecting ring 74 fixed to the housing 1. One end of the second connecting column 75 passes through the second connecting column 75 along its own axis and is connected to the fourth stopper 76. The second connecting ring 74 is provided with an internal thread that cooperates with the rack sleeve 73. The bracket seat 8 is provided with a second accommodating cavity 82. One end of the second connecting column 75 is rotatably arranged in the second accommodating cavity 82 through the third stopper 72 and slides along the extension direction of the bracket seat 8. The second connecting column 75 and the bracket seat 8 are respectively provided with a through hole and a sliding through hole. The third stopper 72 is an axle pin. The axle pin passes through the through hole and the sliding through hole. The two ends of the axle pin are respectively connected to the two sides of the bracket seat 8, thereby generating a positioning function and a supporting function for the second connecting column 75. Since the sliding through hole extends in the extension direction of the bracket seat 8, When the second adjustment hand wheel 71 is rotated, the rack sleeve 73 will rotate synchronously. Since the fourth limiter 76 is fixedly connected to the second connection column 75 and the fourth limiter 76 is arranged between the second adjustment hand and the rack sleeve 73, the rack sleeve 73 is in an idle state at this time, and the second connection ring 74 fixed to the housing 1 is threadedly engaged with the rack sleeve 73, so the housing 1 moves accordingly along the direction of the threaded engagement. Since the housing 1 is connected to the bracket seat 8 through the windage adjustment component 6, the housing 1 swings up and down accordingly around the windage adjustment component 6 during the threaded engagement of the rack sleeve 73 and the second connection ring 74, thereby achieving trajectory adjustment. Since the trajectory adjustment component 7 does not separately adjust the optical element arranged inside the housing 1 when adjusting the trajectory for the gun sight, the coaxiality of the optical element inside the housing 1 is guaranteed, and the imaging quality of the gun sight is guaranteed.
[0043] Please refer to FIG. 1 . In one embodiment, the trajectory adjustment assembly 7 further includes a second hand-feel enhancement device. The second hand-feel enhancement device includes a second placement hole 77 disposed on the side wall of the fourth limiting member 76. A retractable third protrusion 78 is disposed in the second placement hole 77. The inner wall of the rack sleeve 73 is provided with peripheral tooth grooves. The third protrusion 78 is pressed against the peripheral tooth grooves. When the rack sleeve 73 is rotated by an external force, the third protrusion 78 is retracted and abuts against different peripheral tooth grooves, thereby generating a concave-convex feeling. The fourth limiting member 76 is a nail seat. The third protrusion 78 includes a spring and a cone pin. One end of the spring abuts against the bottom of the second placement hole 77, and the other end abuts against the cone pin. The other end of the cone pin abuts against the peripheral tooth groove. When the rack sleeve 73 is rotated by an external force, the third protrusion 78 is retracted and abuts against different peripheral tooth grooves, thereby generating a concave-convex feeling.
[0044] Please refer to Figures 1, 2, 3, 6, 7 and 8. In one embodiment, in order to facilitate the switching of the low-magnification optical path 12 and the high-magnification optical path 13, in this embodiment, the zoom group 31 includes a flip body 32 and two rotating shafts. The flip body 32 is provided with three pairs of opposite planes, namely Ⅰ-Ⅰ, Ⅱ-Ⅱ and Ⅲ-Ⅲ. The two rotating shafts are respectively fixed on the Ⅰ-Ⅰ plane, and the center lines of the two rotating shafts are aligned. The low-magnification optical path 12 and the high-magnification optical path 13 are respectively arranged on the Ⅱ-Ⅱ plane and the Ⅲ-Ⅲ plane. The center lines of the rotating shafts, the low-magnification optical path 12 and the high-magnification optical path 13 are perpendicular to each other. The rotating shafts are rotatably connected to the housing 1, and the center line of the rotating shafts is perpendicular to the main optical path 11. When the magnification needs to be switched, the flip body 32 only needs to be rotated to align the optical path therein with the main optical path 11. For example, when it is necessary to switch from low magnification to high magnification, the flip body 32 is rotated counterclockwise to make the low magnification optical path 12 leave the main optical path 11 and the high magnification optical path 13 align with the main optical path 11. It is convenient and quick.
[0045] Please refer to Figures 1, 2, 3, 6, 7 and 8. In one embodiment, in order to facilitate the adjustment of the deviation between the optical path of the flip body 32 and the main optical path 11 in the left-right direction, in this embodiment, the gun sight further includes a first adjustment pin 39 and an elastic member. The first adjustment pin 39 is threadedly connected to the housing 1, and the center line of the first adjustment pin 39 is parallel to the center line of the rotating shaft. One end of the first adjustment pin 39 is pressed against one of the rotating shafts, and the elastic member is sleeved on the other rotating shaft, and the two ends of the elastic member are pressed against the housing 1 and the flip body 32 respectively. When assembling the flip body 32, if the low-power optical path 12 or the high-power optical path 13 of the flip body 32 has a deviation from the main optical path 11 in the left-right direction, the first adjustment pin 39 can be rotated to push the rotating shaft to move along its center line, thereby adjusting the deviation between the optical path of the flip body 32 and the main optical path 11 in the left-right direction. The elastic member can make the first adjustment pin 39 and the rotating shaft tightly pressed against each other, eliminating the adjustment gap and improving the adjustment accuracy.
[0046] Please refer to FIG. 1, FIG. 2, and FIG. 3. In one embodiment, in order to facilitate the adjustment of the deviation between the optical path of the flip body 32 and the main optical path 11 in the up and down directions, in this embodiment, the gun sight further includes a third adjustment pin 34, which is threadedly connected to the housing 1 and extends out of the inner wall of the housing 1. The flip body 32 is provided with a protrusion 33 facing outwards. When the low-magnification optical path 12 is aligned with the main optical path 11, the protrusion 33 abuts against the third adjustment pin 34. When the flip body 32 is assembled, if there is a deviation between the low-magnification optical path 12 of the flip body 32 and the main optical path 11 in the up and down directions, the third adjustment pin 34 can be rotated to push the flip body 32 to flip around the rotation axis at a certain angle, thereby adjusting the deviation between the low-magnification optical path 12 of the flip body 32 and the main optical path 11 in the up and down directions.
[0047] Please refer to FIG. 1 and FIG. 7 . In one embodiment, to facilitate the flipping operation, the rifle sight further comprises a knob 36 . The knob 36 is fixedly connected to the first rotating shaft 321 . When the knob 36 is rotated, the rotating shaft can be driven to rotate, thereby driving the flip body 32 to rotate synchronously.
[0048] Further, please refer to Figures 6 and 8. In order to enable the flip body 32 to remain at the magnification required by the user, in the present embodiment, the housing 1 is provided with a slide groove facing the hand wheel, and the slide groove is provided with a retractable first protrusion 38. The first protrusion 38 includes a clamping member and a spring. One end of the clamping member faces the knob 36, and the other end is connected to one end of the spring. The other end of the spring is abutted against the inner wall of the slide groove. Under the elastic force of the spring, the clamping member is pressed against the outer surface of the hand wheel. The clamping member and the spring constitute a retractable protrusion. Two spaced-apart first recesses 371 and second recesses 372 are provided on the outer surface of the hand wheel. When the low-magnification optical path 12 is aligned with the main optical path 11, the protrusion is pressed against the inner wall of the first recess 371. When the high-magnification optical path 13 is aligned with the main optical path 11, the protrusion is pressed against the inner wall of the second recess 372. The convex portion is pressed against the hand wheel to prevent the hand wheel from rotating further after it rotates to a predetermined position, thereby ensuring that the flip body 32 is maintained at the magnification required by the user.
[0049] In order to further enhance the stability of the flip body 32 when it is kept at a low magnification, in this embodiment, when the convex part is pressed against the first concave part 371, the convex part is pressed against the inner side wall of the first concave part 371, and a torque is applied to the flip body 32, so that the flip body 32 has a tendency to rotate around the rotation axis while pressing against the housing 1. Specifically, the gun sight shown in Figures 1 and 2 is in a low magnification state. In this state, the convex part is pressed against the outer surface of the hand wheel, the convex part is pressed against an inner side wall of the first concave part 371, and a force F is applied to the hand wheel. The line of action of the force F deviates from the rotation axis of the hand wheel, and a torque M of the force on the rotation axis is formed. The torque M makes the hand wheel have a tendency to rotate counterclockwise. At the same time, because the flip body 32 is pressed against the housing 1, the rotation tendency can be balanced, so that the hand wheel is in a tight state in the low magnification state, thereby enhancing the stability of the hand wheel in the low magnification state, and preventing the hand wheel from shaking slightly in the low magnification state.
[0050] Please refer to Figures 6 and 7. In one embodiment, since the gun sight is assembled by parts, there is a certain gap between the parts. In addition, due to the recoil of the firearm, the gap may be more obvious, so the present application also includes a gap elimination mechanism, which are a first gap elimination mechanism and a second gap elimination mechanism. The first gap elimination mechanism is arranged on a side close to the ballistic adjustment component 7, including a third accommodating cavity 861 and a second elastic member 862. The second elastic member 862 is a compression spring or other elastic material. The second elastic member 862 is arranged in the third accommodating cavity 861. The second elastic member 862 abuts against the fourth accommodating cavity 863 on the shell 1. When the bottom surface of the shell 1 is parallel to the horizontal cross section of the bracket seat 8, the central axis of the third accommodating cavity 861 is aligned with the central axis of the fourth accommodating cavity 863, and the second elastic member 862 is in a compressed state. The second gap elimination mechanism includes a protrusion 871, a second adjustment pin 874 and a third elastic member 873 arranged on the upper surface of the bracket seat 8, the third elastic member 873 is a compression spring or other elastic material, the third elastic member 873 is sleeved on the second adjustment pin 874, the second adjustment pin 874 is threadedly connected to the shell 1, and the third elastic member 873 abuts on the surface of the flange of the second adjustment pin 874, and the second adjustment pin 874 is adjusted to adjust the degree of freedom of the third elastic member 873. Specifically, in order to avoid the third elastic member 873 from detaching from the protrusion 871 when adjusting the degree of freedom of the third elastic member 873, thereby weakening the effect of eliminating the gap, a fifth accommodating cavity 872 is also provided on the protrusion 871, and the diameter of the fifth accommodating cavity 872 is adapted to the outer diameter of the spring, thereby ensuring that the central axis of the fifth accommodating cavity 872 is aligned with the central axis of the third elastic member 873.

Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
