Detailed implementation manners
[0020] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0021] In order to solve the technical problems of the prior art that only the eye point distance can be detected, the aiming scope cannot be subjected to exit pupil detection, the function is single, and the applicable range is narrow, the present invention provides an aiming scope eye point exit pupil detector. By switching and detecting two optical systems, the eye point distance value and the exit pupil distance value can be measured, the function is diversified, the operation process is simple, the accuracy is high, and the repeatability is good.
[0022] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of the aiming scope eye point exit pupil detector in an embodiment of the present invention.
[0023] The present invention provides a sight eye point exit pupil detector, which includes a base 1, a lens barrel 2 and a mounting base 3; the lens barrel 2 is movably installed on the base 1, and a lens group is arranged inside the lens barrel 2; the mounting base 3 is movably installed at one end of the lens barrel 2, and a small hole plate 4 and a first objective lens 5 are arranged on the mounting base 3. The mounting base 3 has a first state in which the small hole plate 4 is coaxial with the lens barrel 2 and a second state in which the first objective lens 5 is coaxial with the lens barrel 2. In the first state, the lens group and the small hole plate 4 form a small hole telescopic structure, and in the second state, the lens group and the first objective lens 5 form a microscopic structure.
[0024] In this embodiment, please refer to Figure 1 , Figure 2 , Figure 10 and Figure 11 , the lens barrel 2 is movably installed on the base 1 and can be adjusted in the direction of approaching and departing from the sight to be measured. The small hole plate 4 and the first objective lens 5 are installed on the mounting base 3. When the mounting base 3 moves, one of the small hole plate 4 and the first objective lens 5 can be coaxial with the lens barrel 2, thus forming two different systems. Specifically, in use, a platform is built and the sight 200 to be measured is placed at a set position at one end of the lens barrel 2 close to the mounting base 3. At this time, the sight 200 to be measured and the lens barrel 2 are coaxially arranged in the first direction. The mounting base 3 is driven to be in the first state. At this time, it is a small hole telescopic structure. The operator observes from the other end of the lens barrel 2 and adjusts the position of the lens barrel 2 in the first direction in real time until the small hole on the small hole plate 4 coincides with the eye point of the sight 200 to be measured. Then the eye point position can be located and the displacement data, that is, the eye point data, can be read. Then the lens barrel 2 is moved to the initial position, and the mounting base 3 is driven to be in the second state. At this time, it is a microscopic structure. The operator observes again and adjusts the position of the lens barrel 2 in the first direction in real time until the vertex of the sight 200 to be measured is observed. Then the vertex position can be located and the displacement data, that is, the vertex data, can be read. The difference between the eye point data and the vertex data is the eye point distance value, and then the eye point distance detection is completed. When performing the exit pupil detection, the mounting base 3 is driven to be in the second state, and the vertex and the exit pupil point of the sight 200 to be measured are observed respectively. The difference between the two is the exit pupil distance value. Through the switching detection of the two optical systems, the eye point distance value and the exit pupil distance value can be measured in this application. The functions are diversified, and the operation process is simple, with high precision and good repeatability.
[0025] The specific form of the movable installation of the mounting base on the lens barrel is not limited. It can be that the mounting base is slidably installed at one end of the lens barrel, or the mounting base is rotatably installed at one end of the lens barrel.
[0026] In this embodiment, please refer to Figure 2and Figure 3 The middle part of the mounting base 3 is rotatably mounted on the lens barrel 2, and the small hole plate 4 and the first objective lens 5 are respectively arranged at opposite ends of the mounting base 3.
[0027] Specifically, an installation protrusion 24 is convexly formed on the upper side of one end of the lens barrel 2. The installation protrusion 24 is provided with a through hole along the first direction. The aiming mirror eye point and exit pupil detector further includes a rotating shaft, and the rotating shaft is rotatably mounted in the through hole through a bearing. The middle part of the mounting base 3 is fixedly connected to one end of the rotating shaft. The distances from the two mounting holes to the through hole are the same and are the same as the distance from the through hole to the lens barrel 2. When the mounting base 3 rotates, the mounting holes can be coaxially arranged with the lens barrel 2, so as to ensure that the small hole plate 4 or the first objective lens 5 is coaxially arranged with the lens barrel 2.
[0028] Furthermore, mounting holes are provided at both opposite ends of the mounting base 3, and the small hole plate 4 and the first objective lens 5 are respectively detachably mounted in the mounting holes. Such a setting is beneficial to processing and manufacturing.

The aiming mirror eye point and exit pupil detector further includes locking screws. When the small hole plate 4 and the first objective lens 5 are mounted in the mounting holes, the locking screws are in threaded cooperation with the threaded holes and one end abuts against the small hole plate 4 or the first objective lens 5 to lock the small hole plate 4 or the first objective lens 5.
[0030] In another embodiment, the mounting base 3 is slidably mounted at one end of the lens barrel 2, and the small hole plate 4 and the first objective lens 5 are arranged on the mounting base 3 at intervals along the sliding direction of the mounting base 3, so that when the mounting base 3 slides, one of the small hole plate 4 and the first objective lens 5 can be coaxially arranged with the lens barrel 2.
[0031] In this embodiment, please refer to Figure 3 and Figure 4 To prevent the mounting base 3 from accidentally moving after moving to the first state or the second state, resulting in deviation, the aiming mirror eye point and exit pupil detector further includes a locking component 6. The locking component 6 is arranged on the lens barrel 2. When the mounting base 3 moves to the first state or the second state, the locking component 6 is connected to the mounting base 3 to limit the movement of the mounting base 3. By providing the locking component 6, the mounting base 3 can be well restricted to prevent it from accidentally moving during use.
[0032] In this embodiment, please refer toFigure 3 and Figure 4 The mounting base 3 is provided with two locking grooves 31, and the two locking grooves 31 respectively correspond to the small hole plate 4 and the first objective lens 5; the locking assembly 6 includes a locking member 61, and the locking member 61 is movably mounted on the lens barrel 2 along a first direction, so that when the mounting base 3 moves to the first state or the second state, the locking member 61 extends into one of the locking grooves 31.
[0033] Specifically, one side of the mounting base 3 facing the mounting protrusion 24 is provided with locking grooves 31, the two locking grooves 31 are respectively a first locking groove 31 corresponding to the small hole plate 4 and a second locking groove 31 corresponding to the first objective lens 5, the locking member 61 is movably mounted on the mounting protrusion 24, when the mounting base 3 rotates to the first state, the first locking groove 31 faces the locking member 61, and then the locking member 61 moves towards the first locking groove 31 and extends into the first locking groove 31, through the limiting cooperation between the locking member 61 and the first locking groove 31, the positioning purpose is achieved, when the mounting base 3 rotates to the second state, the second locking groove 31 faces the locking member 61, and then the locking member 61 moves towards the second locking groove 31 and extends into the second locking groove 31, and the limiting is carried out through the limiting cooperation between the locking member 61 and the second locking groove 31.
[0034] Further, one side of the mounting protrusion 24 facing the mounting base 3 is provided with a receiving hole, the locking member 61 is movably mounted in the receiving hole, the locking assembly 6 further includes an elastic member 62, the elastic member 62 is located in the receiving hole, and both ends of the elastic member 62 are connected to the locking member 61 and the bottom of the receiving hole, and the elastic member 62 is used to drive the locking member 61 to move towards the locking groove 31.
[0035] Further, the is a steel ball, the steel ball is adapted to the receiving hole, and the locking groove 31 is an arc groove adapted to the steel ball.
[0036] In this embodiment, please refer to Figure 5 , the base 1 is provided with a main scale 14; the lens barrel 2 is provided with a vertex vernier 75 and an eye point vernier 76, and the vertex vernier 75 and the eye point vernier 76 are arranged at intervals along a direction away from the mounting base 3.
[0037] Specifically, since the working surfaces of the small-aperture telescopic structure and the microscopic structure are different, in order to facilitate reading, a vertex vernier 75 and an eye-point vernier 76 are installed on the lens barrel 2. The vertex vernier 75 and the eye-point vernier 76 can move along with the lens barrel 2 in the first direction. By cooperating with the main scale 14, the relevant displacement data can be read. The vertex vernier 75 corresponds to the working surface of the microscopic structure, and the eye-point vernier 76 corresponds to the working surface of the small-aperture telescopic structure. In actual use, when the mounting base 3 is switched to the first state, that is, when the optical system is the small-aperture telescopic structure, the eye-point vernier 76 is used to cooperate with the main scale 14 for reading. When the mounting base 3 is switched to the second state, that is, when the optical system is the microscopic structure, the vertex vernier 75 is used to cooperate with the main scale 14 for reading. The difference between the reading of the eye-point vernier 76 and the reading of the vertex vernier 75 is the eye-point distance value. There is no need to rely on other equipment. Only by reading separately under the two optical system states, the measured eye-point distance value can be calculated. The operation process is simple, with high precision and good repeatability.
[0038] In this embodiment, please refer to Figure 6 and Figure 7 , the sight eye-point exit pupil detector further includes a connecting seat 7. The connecting seat 7 is movably installed on the base 1 along the first direction. The lens barrel 2 is arranged on the connecting seat 7. The connecting seat 7 and the base 1 form a five-dimensional adjustment mechanism so that the position of the lens barrel 2 is adjustable.
[0039] Specifically, since the measured sight 200 is fixedly installed on the platform and does not move, it is necessary for the lens barrel 2 to be coaxial with the measured sight 200 during the test. Therefore, before the test, the lens barrel 2 needs to be adjusted. In order to facilitate the adjustment of the lens barrel 2, the five-dimensional adjustment mechanism formed by the connecting seat 7 and the base 1 can drive the lens barrel 2 to move in the first direction, the second direction, and the vertical direction. The first direction and the second direction are both horizontal directions and perpendicular to each other. At the same time, it can also drive the lens barrel 2 to rotate on the axis in the vertical direction and the axis in the second direction, so as to facilitate the optical axis alignment in different optical path states and ensure the accuracy of the test.
[0040] In this embodiment, please refer to Figure 6 and Figure 7 , the lens barrel 2 is movably arranged on the connecting seat 7 along the vertical direction and the second direction. The first direction and the second direction are perpendicular to each other.
[0041] Specifically, the connecting seat 7 includes a first connecting plate 71, a second connecting plate 72, and a scissor lift mechanism 73. The first connecting plate 71 is slidably mounted on the base 1 along the first direction. The second connecting plate 72 is slidably mounted on the upper side of the first connecting plate 71 along the second direction. The scissor lift mechanism 73 is mounted on the second connecting plate 72. The lens barrel 2 is mounted on the scissor lift through a bracket 8. The second connecting plate 72 can drive the lens barrel 2 to move in the second direction, and the scissor lift mechanism 73 can drive the lens barrel 2 to move in the vertical direction, thereby realizing the adjustment of the lens barrel 2 in the vertical direction and the second direction.
[0042] Further, the aiming eyepoint exit pupil detector further includes a driving assembly, and the driving assembly is connected to the first connecting plate 71 to drive the first connecting plate 71 to move.
[0043] Furthermore, the first connecting plate 71 is provided with a threaded hole extending along the first direction. The driving assembly includes a lead screw 74 and a handwheel. The lead screw 74 is rotatably mounted on the base 1 along the axis in the first direction. The lead screw 74 is in threaded cooperation with the first connecting plate 71. The handwheel is mounted on one end of the lead screw 74 to drive the connecting plate to move by rotating the lead screw 74.
[0044] Further, the vertex vernier 75 and the eyepoint vernier 76 are both mounted on the first connecting plate 71.
[0045] In this embodiment, please refer to Figure 6 and Figure 7 , the base 1 includes a first base body 11, a second base body 12, and a third base body 13. The second base body 12 is rotatably mounted on the first base body 11 along the axis in the second direction. The third base body 13 is rotatably mounted on the second base body 12 along the axis in the vertical direction. The connecting seat 7 is slidably mounted on the third base body 13 along the first direction.
[0046] Specifically, one end of the second base body 12 is rotatably mounted on the first base body 11. The middle region of the third base body 13 is rotatably mounted on the upper side of the second base body 12 along the axis in the vertical direction. The second base body 12 can drive the lens barrel 2 to rotate around the axis in the second direction, and the third seat can drive the lens barrel 2 to rotate around the axis in the vertical direction. Through the combined use of the connecting seat 7 and the base 1, the height adjustment, lateral adjustment, longitudinal adjustment, pitch adjustment, and azimuth adjustment of the lens barrel 2 can be realized, which is convenient for optical axis alignment under different optical path states.
[0047] Further, the other end of the second seat body 12 is provided with a threaded hole. The base 1 further includes an adjusting member 15. The adjusting member 15 is located between the first seat body 11 and the second seat body 12. One end of the adjusting member 15 is provided with an external thread. The adjusting member 15 is threadedly connected to the second seat body 12. The other end of the adjusting member 15 abuts against the first seat body 11, so as to adjust the rotation angle of the second seat body 12 relative to the first seat body 11 by rotating the adjusting member 15.
[0048] Further, the main scale 14 is mounted on the third seat body 13.
[0049] In this embodiment, please refer to Figure 8 , the lens group includes an eyepiece 21, a reticle group 22, and a second objective lens 23 arranged at intervals along the direction towards the mounting base 3.
[0050] Specifically, the eyepiece 21 and the second objective lens 23 are respectively mounted at opposite ends of the lens barrel 2. The reticle group 22 is mounted in the middle of the lens barrel 2. An optical system can be formed by the eyepiece 21, the reticle group 22, the second objective lens 23, and the small hole plate 4 or the first objective lens 5 to complete the relevant detection of the measured sight 200.
[0051] In this embodiment, please refer to Figure 9 , the reticle group 22 is provided with scales. By setting scales on the reticle group 22, the exit pupil diameter of the measured sight 200 can be measured, and the measurement range of this application can reach 22 mm, with a large measurement range.
[0052] Further, the reticle group 22 includes a reticle plate. The reticle plate is arranged in the lens barrel 2, and the reticle plate is provided with scales.
[0053] For a better understanding of the present invention, the following will Figures 1 to 11 describe the technical solution of the present invention in detail: Before detection, a platform is built at a set position at one end of the lens barrel 2 close to the mounting base 3. The measured sight 200 is installed on the platform. Subsequently, the position of the lens barrel 2 is adjusted through the connecting seat 7 and the base 1 to make the lens barrel 2 coaxially arranged with the measured sight 200. The specific adjustment method is as follows: the second connecting plate 72 can drive the lens barrel 2 to move in the second direction, the scissor lift mechanism 73 can drive the lens barrel 2 to move in the vertical direction, so as to realize the adjustment of the lens barrel 2 in the vertical direction and the second direction. The second seat body 12 can drive the lens barrel 2 to rotate around the axis in the second direction, and the third seat can drive the lens barrel 2 to rotate around the axis in the vertical direction. Through the coordinated cooperation of the above components, the adjustment of the lens barrel 2 is completed.
[0054] During detection, rotate the mounting base 3 to make it in the first state. At this time, it is a small-hole telescopic structure. The operator observes from the other end of the lens barrel 2 and adjusts the position of the lens barrel 2 in the first direction in real time until the small hole on the small-hole plate 4 coincides with the eye point of the measured sighting telescope 200. Then the eye point position can be located and the displacement data, i.e., the eye point data, can be read. Then move the lens barrel 2 to the initial position, rotate the mounting base 3 to make it in the second state. At this time, it is a microscopic structure. The operator observes again and adjusts the position of the lens barrel 2 in the first direction in real time until the vertex of the measured sighting telescope 200 is observed. Then the vertex position can be located and the displacement data, i.e., the vertex data, can be read. The difference between the eye point data and the vertex data is the eye point distance value, and thus the eye point distance detection is completed. When performing exit pupil detection, rotate the mounting base 3 to make it in the second state, observe the vertex and the exit pupil point of the measured sighting telescope 200 respectively. The difference between the two is the exit pupil distance value. There are scales on the reticle. The measured exit pupil is imaged on the reticle group 22. The exit pupil diameter of the measured sighting telescope 200 can be read using the scales on the reticle, and thus the exit pupil diameter detection of the measured sighting telescope 200 is completed.
[0055] This application integrates the detection of the eye point distance, exit pupil diameter and exit pupil distance of a sighting telescope, and is used for the production and detection of white light sighting telescopes, infrared sighting telescopes and low-light-level sighting telescopes. It can conveniently and quickly detect the exit pupil and eye point indicators, with low requirements for testers, simple operation and high precision.
