Description

Technical Field

[0001] This utility model relates to the technical field of aiming condition checkers for gun sights, specifically an aiming condition checker for gun sights. Background Technology

[0002] A gun sight aiming condition checker is a device used to assist in checking the aiming condition of a shooter. It is mainly used in shooting training scenarios to help instructors observe the aiming condition of shooters, identify and correct problems in a timely manner, and improve the effectiveness and quality of shooting training.

[0003] Existing methods for checking the aiming view of firearms primarily involve using a vehicle-mounted machine gun aiming sight. Before inspection, the firearms sight must be calibrated to ensure its aiming view matches that of the aiming sight inserted into the barrel. The operator then re-aims and fires, and the inspector observes the operator's aiming view through the aiming sight. However, the observed view differs from the actual view; while the vertical alignment is consistent, the horizontal alignment is reversed. Because the prior calibration of the firearms sight is time-consuming, and the inspector must observe from the roof of the armored vehicle, it is heavily influenced by weather conditions, making inspections unsuitable for rainy or snowy weather. Therefore, we propose a firearms sight aiming view inspection device. Utility Model Content

[0004] The purpose of this invention is to provide a gun sight aiming view inspector to solve the problems mentioned in the background section regarding existing gun sight aiming view inspection methods. These methods primarily rely on a vehicle-mounted machine gun aiming sight. Before inspection, the gun sight must be calibrated to ensure its aiming view matches that of the aiming sight inserted into the barrel. The operator then re-aims and fires, and the inspector observes the operator's aiming view through the aiming sight. However, the observed view differs from the actual view; while the vertical alignment is consistent, the horizontal alignment is reversed. Furthermore, the requirement for gun sight calibration before inspection is time-consuming, and the inspector must observe from the roof of an armored vehicle, making it highly susceptible to weather conditions, particularly in rainy or snowy weather.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a gun sight aiming scene checker, comprising: a beam splitter, which splits the real-time scene of the gun sight into two paths through a beam splitter prism; a fiber optic hose is fixedly connected to the beam splitter, and an inspection eyepiece is fixedly connected to the other end of the fiber optic hose; a clamping device is fixedly connected to the end of the beam splitter near the objective lens of the sight, and the clamping device quickly clamps the beam splitter onto the sight.

[0006] The beam splitting device includes a housing, inside which a first right-angle prism is fixedly connected, and a second right-angle prism is fixedly connected to the inclined side of the first right-angle prism. The inclined surfaces of the first right-angle prism and the second right-angle prism are bonded together with optical adhesive, and a beam splitting film is coated on the inclined surface of the second right-angle prism.

[0007] The clamping device includes a fixed base fixedly connected to the outer shell, a fixed rod fixedly connected to the fixed base, a rotating base rotatably connected to the fixed base, an arc-shaped groove on the rotating base, the fixed rod passing through the arc-shaped groove and slidingly engaging with the inner wall of the arc-shaped groove, a rotating rod one fixedly connected to the rotating base, a movable arm rotatably connected to the rotating rod one, a rotating rod two fixedly connected to the other end of the movable arm, and a pressing block rotatably connected to the rotating rod two.

[0008] It also includes: a fixed ring, on which a rotating rod three is uniformly fixedly connected circumferentially, the rotating rod three being rotatably connected to the pressing block, the side of the pressing block facing the center of the fixed ring being used to fit the outer wall of the scope, and a rotating cover being fixedly connected to the outside of the rotating seat, the rotating cover driving the rotating seat to rotate.

[0009] The angle between the inclined planes of the first right-angle prism and the second right-angle prism is 45°, and the beam splitting film is parallel to the mating surface of the two prisms.

[0010] The extrusion block is made of silicone, and the extrusion block adapts to the curvature of the outer wall of the scope through the elastic deformation of the silicone material.

[0011] The beam-splitting film is a multilayer dielectric film with a reflectivity and transmittance of 50% for visible light.

[0012] Among them, the rotating rod is provided with multiple sets and corresponds to the extrusion block.

[0013] This utility model has at least the following beneficial effects:

[0014] When in use, this utility model uses a beam splitter to precisely divide the aiming scene into two paths, which does not affect the user's normal aiming and allows for real-time monitoring and guidance by inspection personnel. The clamping device can quickly and securely clamp to scopes of different sizes without causing damage, combining convenience and protection. The entire device can effectively help operators correct their movements and master the optimal aiming scene, providing strong support for live-fire shooting and demonstrating high practicality and reliability.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Please see Figures 1 to 4 This utility model provides a technical solution: a gun sight aiming scene checker, comprising: a beam splitter 1, characterized in that: the beam splitter 1 splits the real-time scene captured by the gun sight into two paths through a beam splitter prism; a fiber optic hose 2 is fixedly connected to the beam splitter 1, and an inspection eyepiece 3 is fixedly connected to the other end of the fiber optic hose 2; a clamping device 4 is fixedly connected to the end of the beam splitter 1 near the objective lens of the sight, and the clamping device 4 quickly clamps the beam splitter 1 onto the sight; the beam splitter 1 can accurately and stably split the real-time scene captured by the gun sight into two paths, one of which maintains its original path and can continue to be observed by the sight user in the conventional way. To ensure that it performs aiming tasks without interference in actual use scenarios, another view is directed to the inspection channel so that professionals can monitor and evaluate the aiming situation. The fiber optic hose 2 is made of a special material with excellent flexibility and can be flexibly adjusted so that inspectors can observe from different angles. Through the inspection eyepiece 3, inspectors can see the image after beam splitting clearly and sharply, providing a solid visual basis for accurately judging the aiming situation. The holding device can quickly and firmly clamp the beam splitter 1 onto the scope without damaging the scope, and is easy to disassemble and install quickly, adapting to different models of gun scopes.

[0023] The beam splitter 1 includes a housing 11, inside which a first right-angle prism 12 is fixedly connected. A second right-angle prism 13 is fixedly connected to the inclined side of the first right-angle prism 12. The inclined surfaces of the first right-angle prism 12 and the second right-angle prism 13 are bonded together with optical adhesive. A beam splitting film 14 is coated on the inclined surface of the second right-angle prism 13. The housing 11 can effectively protect the internal optical components from external dust, collisions, and other influences. The prisms are made of high-transmittance optical glass to ensure that light can pass through smoothly and reduce light loss. The beam splitting film 14 can reflect and transmit light in a certain proportion, thereby achieving beam splitting of the scene.

[0024] The clamping device 4 includes a fixed base 41 fixedly connected to the outer shell 11, a fixed rod 42 fixedly connected to the fixed base 41, a rotating base 43 rotatably connected to the fixed base 41, an arc-shaped groove 44 opened on the rotating base 43, the fixed rod 42 passing through the arc-shaped groove 44 and slidingly engaging with the inner wall of the arc-shaped groove 44, a first rotating rod 45 fixedly connected to the rotating base 43, a movable arm 46 rotatably connected to the first rotating rod 45, a second rotating rod 47 fixedly connected to the other end of the movable arm 46, and a pressing block 48 rotatably connected to the second rotating rod 47. It also includes: a fixing ring 49, on which rotating rods 410 are uniformly fixedly connected circumferentially. The rotating rods 410 are rotatably connected to the pressing block 48. The side of the pressing block 48 facing the center of the fixing ring 49 is used to fit against the outer wall of the scope. A rotating cover 411 is fixedly connected to the outside of the rotating seat 43. The rotating cover 411 drives the rotating seat 43 to rotate. The fixing seat 41 provides stable support for the entire clamping device 4. The fixing rod 42 plays a positioning and guiding role. When the rotating seat 43 rotates, the fixing rod 42 slides in the arc-shaped groove 44, which limits the rotation range of the rotating seat 43.

[0025] In use, by placing the clamping device 4 on the outside of the scope, rotating the rotating cover 411 counterclockwise causes the rotating base 43 to rotate counterclockwise under the limit of the fixed rod 42. This causes the movable arm 46 to move towards the fixed ring 49 with the rotating rod 45 as the fulcrum. Under the combined action of the rotating rod 47 and the rotating rod 410, the pressing block 48 retracts inward with the rotating rod 410 as the fulcrum. This allows the clamping device 4 to clamp the scope evenly and stably from multiple directions, greatly improving the reliability and stability of the clamping. When disassembly is required, the rotating cover 411 can be rotated clockwise for quick disassembly.

[0026] The angle between the inclined planes of the first right-angle prism 12 and the second right-angle prism 13 is 45°. The beam splitting film 14 is parallel to the mating surface of the two prisms. This design ensures the accuracy of the beam splitting effect. The actual scene of the horizontal light path can be reflected into a 90° angle and transmitted to the fiber optic hose 2, and then transmitted to the inspection eyepiece 3 through the fiber optic hose 2.

[0027] The compression block 48 is made of silicone, which has good elasticity and wear resistance. When clamping the scope, it can provide sufficient friction to prevent slippage and avoid scratching or squeezing damage to the outer wall of the scope, thus playing a good protective role.

[0028] The beam splitter 14 is a multilayer dielectric film with a reflectivity and transmittance of 50% for visible light. It is made through a special coating process and has extremely high optical performance stability. This design ensures that the brightness of the two images after beam splitting is basically the same, making it easy for inspectors and scope users to clearly observe the scene.

[0029] The rotating rod 410 is provided with multiple sets corresponding to the pressing block 48. The coordinated action of the multiple sets of rotating rods 410 and pressing block 48 can clamp the scope from multiple directions, greatly improving the stability and firmness of the clamping, and ensuring that the beam splitter 1 will not loosen or shift during use.

[0030] In use, the aiming view checker is fixed to the front of the gun sight. At this time, the beam splitter 1 can be quickly fixed to different types of sights by rotating the cover 411 by rotating the lever. The inspector is behind the operator and checks the operator's aiming view by holding the inspection eyepiece 3. The inspector can guide the operator to correct any mistakes in the aiming view and let the operator know the best aiming view, thus laying the foundation for the next live-fire shooting.

[0031] Example 2

[0032] In this second embodiment, the other structures remain unchanged. The difference from the first embodiment is that the extrusion block 48 can also be made of other soft support materials such as nitrile rubber and polyurethane elastomer. The selection can be made as appropriate according to the situation, making the selection more convenient and quick.
