Description

Technical Field

[0001] This application belongs to the technical field of aiming devices, and particularly relates to a dot sight with a square window. Background Art

[0002] Reflective sights are widely used because their optical systems are relatively simple, and they are small in size and convenient to carry. Their main principle is that the light emitted by a light source of a specific wavelength travels along the optical path and irradiates onto a dichroic mirror with a coating treatment. After being reflected by the dichroic mirror, it then enters the shooter's eyes to complete aiming.

[0003] In order to ensure that the aiming field of view of the sight is relatively large and avoid the influence of the external environment on the optical path to cause parallax, those skilled in the art often set the optical path system on a square inner tube and then install the inner tube inside the sight body, so as to effectively avoid the influence of the external environment. For example, the invention application with the publication number CN115265275A and the name "Sight" includes a square tube and a sight body. The interior of the square tube is provided with a light source group and a dichroic mirror for reflecting light. A flange is provided on the outer periphery of the front end of the square inner tube, and an elastic ring is provided on the outer periphery of the front end of the sight body. The elastic ring is provided with a groove that can cooperate with the flange. The inner tube rotates around the linear fulcrum formed by the flange under the constraint of the elastic ring in response to the force applied by the adjustment mechanism to complete the adjustment. However, after the adjustment of the sight with this structure is completed, due to the influence of the freedom of restoration of the elastic ring, the inner tube will inevitably have a certain displacement, which is likely to cause parallax in the sight and further affect the accuracy of the shooting target.

[0029] In addition, the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and may be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0031] A telescopic sight is often used to be installed on a firearm to improve the aiming accuracy and reduce the shooting difficulty. In the present application, the meaning of the "ocular side" is the end of the telescopic sight close to the shooter during actual operation, and the meaning of the "object side" is the end of the telescopic sight close to the target during actual operation, that is, the end far from the shooter.

[0032] The following describes the specific implementation of the present application in more detail with specific embodiments:

[0033] Please refer to Figure 1 、 Figure 2 、 Figure 5 , the present application provides a dot sight with a square window, including a mirror body 1, an inner tube 2, and an adjustment mechanism. There is a cavity 3 axially penetrating through the mirror body 1. The inner tube 2 is installed in the cavity 3. In the case where the cross-sectional shape of the inner tube 2 is the same as the cross-sectional shape of the mirror body 1, in this embodiment, the cross-sectional shapes of both the inner tube 2 and the mirror body 1 are square.

[0034] In some embodiments, the cross-sectional shapes of both the inner tube 2 and the mirror body 1 are triangular or other polygons, etc.

[0035] A light channel 4 is arranged inside the inner tube 2. A beam splitter 5 is arranged at one end of the inner tube 2 close to the object side along the light channel 4, and a light source group 6 is arranged at one end close to the eyepiece side. The light source group 6 is used to emit a beam of a preset wavelength to the beam splitter 5, and the beam splitter 5 is used to reflect the beam to the human eye, thereby achieving aiming. It should be noted here that the color of the beam can be red, green, yellow, etc., which is not limited here; the beam splitter 5 is a lens with a certain thickness, such as a cemented lens or other types of lenses, and a layer or multiple layers of reflection films with a certain transmittance are usually coated on the surface of the lens, such as a red film, a green film, etc.

[0036] The light source group 6 is arranged on the bottom surface of the inner tube 2 at one end close to the eyepiece side. The light source group 6 at least includes a light-emitting component capable of emitting a beam of a preset wavelength to the beam splitter 5, such as an LED (Light-Emitting Diode); therefore, when the adjusting mechanism drives the inner tube 2, the position of the light-emitting component is stationary relative to the inner tube 2, so the position of the beam irradiated on the beam splitter 5 also changes, and the position of the beam observed by the shooter also changes accordingly, thereby achieving the effect of ballistic compensation or windage compensation.

[0037] The adjusting mechanism includes two adjusting components, namely a ballistic adjusting component 18 and a windage adjusting component 19. The ballistic adjusting component 18 is arranged on one side of the inner tube 2 in the vertical direction, and the windage adjusting component 19 is arranged on one side of the inner tube 2 in the horizontal direction; the adjusting mechanism also includes two reset mechanisms respectively corresponding to the ballistic adjusting component 18 and the windage adjusting component 19, namely a first reset structure 26 and a second reset structure 27.

[0038] Specifically, the adjusting mechanism is arranged at one end of the aiming scope close to the eyepiece side. In this embodiment, the ballistic adjusting component 18 is arranged at the top position of the aiming scope, and the corresponding first reset structure 26 is arranged inside the lens body 1 and below the inner tube 2; the windage adjusting component 19 is arranged on any one of the two sides of the aiming scope, and the corresponding second reset structure 27 is arranged on the other side; the first reset structure 26 and the second reset structure 27 can be, but are not limited to, shrapnel or springs.

[0039] The ballistic adjustment assembly and the windage adjustment assembly include the stud sleeve 20, the adjusting stud 21, and the stud head 22. The mirror body 1 is provided with a third hole 23 and a fourth hole 24 provided at the bottom of the third hole 23 and communicating with the inner cavity. The adjusting stud 21 is rotatably arranged in the third hole 23. The stud sleeve 20 is connected to the third hole 23 and jointly limits the axial movement of the adjusting stud 21 along the third hole 23 with the third hole 23. The adjusting stud 21 is provided with a fifth hole 25, and the fifth hole 25 is a threaded hole. One end of the stud head 22 can be in threaded cooperation with the fifth hole 25.

[0040] It should be noted here that the fourth hole 24 can be, but is not limited to, a non-circular hole.

[0041] In some embodiments, the end of the stud head 22 is inserted into the fifth hole 25. The fourth hole 24 is a non-circular hole and limits the rotation of the stud head 22 relative to the fifth hole 25. The stud head 22 is threadedly connected to the fourth hole 24.

[0042] Please refer to Figure 2-6 , the accommodating part at least includes a first ball socket column 7 and a first ball socket 8. The supporting part includes a second ball socket column 9 and a second ball socket 10. The fulcrum part at least includes a ball 11. At least part of the first ball socket 8 and the second ball socket 10 are in contact with the ball 11. The ball 11 provides a pivoting fulcrum for the first ball socket column 7, and the second ball socket 10 provides a supporting effect for the ball 11.

[0043] It should be noted here that the ball 11 can be, but is not limited to, a steel ball. Any shape of the fulcrum part that is spherical or partially spherical falls within the protection scope of the present invention.

[0044] The first ball socket column 7 is arranged on the lower surface of the outer periphery of the inner tube 2. The second ball socket column 9 is arranged on the lower surface of the inner periphery of the mirror body 1. The second ball socket column 9 corresponds to the first ball socket column 7. The first ball socket column 7 is a cylinder with a certain length. One end of the first ball socket column 7 is connected to the inner tube 2, and the other end is provided with a first ball socket 8. The second ball socket column 9 is also a cylinder with a certain length arranged inside the mirror body 1. The central axis of the second ball socket column 9 is aligned with the central axis of the first ball socket column 7. One end of the second ball socket column 9 close to the first ball socket column 7 is provided with a second ball socket 10. The ball 11 is arranged between the first ball socket column 7 and the second ball socket column 9.

[0045] Specifically, the first ball socket column 7 is integrally formed with the inner tube 2, but connection methods such as detachable connection or fixed connection can also be adopted, such as threaded connection, disassembly and assembly connection, and adhesive connection. To facilitate the installation and maintenance of the second ball socket column 9, in this embodiment, the second ball socket column 9 is detachably connected to the lens body 1. More specifically, the second ball socket column 9 is further provided with two connecting ears 12, the connecting ears 12 are provided with first threaded holes 121, the bottom surface of the lens body 1 near the object side is provided with a groove 13, the groove 13 is provided with a first hole 14 and a second threaded hole 131 corresponding to the first threaded hole 121. After the second ball socket column 9 extends into the lens body 1 through the first hole 14, the assembler can use a suitable locking screw or other locking parts to detachably install the second ball socket column 9 on the lens body 1 through the first threaded hole 121 and the second threaded hole 131. Here, it should be noted that the detachable installation can be in the form of bonding, plug-in connection, etc.

[0046] The ball 11 is independently arranged between the first ball socket 8 and the second ball socket 10. In order to achieve a better pivoting effect, the first ball socket 8 and the ball 11 both have a uniform and smooth surface, and the distances from the points on the ball socket surfaces of the first ball socket 8 and the second ball socket 10 to the center of the ball 11 are the same as the radius of the ball 11, so that the first ball socket 8 and the ball 11 have good pivoting properties, making the adjustment smoother and more accurate; in addition, it should also be noted that when performing ballistic adjustment, the inner tube 2 will tilt up and down relative to the lens body 1 with the ball 11 as the fulcrum under the drive of the ballistic adjustment assembly 18, which means that the first ball socket column 7 tilts forward and backward on the ball 11. Specifically, as Figure 7 shown, during the adjustment process, the distance between the first wall surface 71 of the first ball socket column 7 and the second wall surface 91 of the second ball socket column 9 is shortening. To prevent the first ball socket column 7 and the second ball socket column 9 from being squeezed during the adjustment process, resulting in adjustment errors, when the center lines of the first ball socket column 7 and the second ball socket column 9 are aligned, the vertical distance from the first wall surface 71 to the second wall surface 91 cannot be zero. The specific minimum distance can be determined according to the range of ballistic adjustment. Therefore, in this embodiment, the diameters of the first ball socket 8 and the second ball socket 10 are both smaller than the diameter of the ball 11.

[0047] In some embodiments, the diameter of the first ball socket 8 is greater than or equal to the diameter of the ball 11, while the diameter of the second ball socket 10 is smaller than the diameter of the ball 11; or, the diameter of the first ball socket 8 is smaller than the diameter of the ball 11, while the diameter of the second ball socket 10 is greater than or equal to the diameter of the ball 11.

[0048] In this embodiment, since the inner tube 2 is driven by the ballistic adjustment assembly 18 to tilt up and down relative to the mirror body 1 with the ball 11 as the fulcrum, but due to the upward pressure of the ball 11 on the first ball socket 8 and the gravity of the inner tube 2 itself, the inner tube 2 is in a dynamically unbalanced state during the movement process, and the moving direction is prone to deviation, and the expected adjustment effect cannot be achieved. In order to make the inner tube 2 in a dynamically balanced state during ballistic adjustment or windage adjustment, pressing members are provided on both sides of the inner tube 2. After passing through the counterbore 15 on the mirror body 1, the pressing members abut against the second hole 16 provided on the side of the inner tube 2. The pressing member at least includes a pin 17, and the pressing member maintains the dynamic balance of the inner tube 2 during ballistic adjustment or ballistic adjustment, so as to ensure that the displacement direction of the inner tube 2 does not deviate during the process of the adjustment mechanism driving the inner tube.

[0049] It should be noted here that the second hole 16 can be, but is not limited to, a waist-shaped hole, and can also be other non-circular holes, special-shaped holes, etc.

[0050] Please refer to Figure 8 , in this embodiment, the second hole 16 is a waist-shaped hole, and the groove width dimension D of the waist-shaped hole is larger than the dimension d of the end of the pressing member, so that the pressing member can abut against the waist-shaped hole and have a sliding fit with the waist-shaped hole during compensation adjustment. The pressing member has a reaction force (not shown) on the inner tube 2, and the direction of the reaction force changes with the movement of the inner tube 2. Therefore, it is possible to prevent the inner tube 2 from tilting left and right due to its own gravity during the ballistic adjustment process; at the same time, since the inner tube 2 moves left and right relative to the mirror body 1 with the ball 11 as the fulcrum during windage adjustment, the second hole 16 also moves synchronously. In order to prevent the pressing member from blocking the movement of the inner tube 2 during windage adjustment, the length L of the waist-shaped hole can be determined according to the actual windage adjustment range. The purpose of such a design is to enable the inner tube 2 to have sufficient movement space during windage adjustment.

[0051] When the above-mentioned sight is adjusted for ballistics, the shooter can use tools such as a wrench to turn the adjusting screw 21, causing the adjusting screw 21 to rotate within the third hole 23. Since the adjusting screw 21 is threadedly connected to the screw head 22, the screw head 22 moves axially back and forth along the fourth hole 24 and the fifth hole 25 under the drive of the adjusting screw 21. When the screw head 22 applies a perpendicular pressure to the inner tube 2, the end of the inner tube 2 near the eyepiece will move along the direction of the pressure, and the first reset structure 26 will be compressed accordingly. The end of the inner tube 2 near the objective will tilt up and down with the ball 11 as the fulcrum. At the same time, due to the existence of the waist-shaped hole and the pressing member, the inner tube 2 has a clear moving direction and range of movement. Therefore, the inner tube 2 avoids the phenomenon of deviation during the movement, thereby achieving precise adjustment. When the adjusting screw 21 is turned in the opposite direction, when the pressure of the screw head 22 on the inner tube 2 gradually decreases, since the first reset structure 26 has a reaction force on the inner tube 2, it will push the inner tube 2 to move in the opposite direction. At this time, the inner tube 2 continues to pivot with the ball 11 as the fulcrum until the position adjusted by the shooter is reached.

[0052] When the above-mentioned sight is adjusted for windage, the shooter can use tools such as a wrench to turn the adjusting screw 21, causing the adjusting screw 21 to rotate within the third hole 23. Since the adjusting screw 21 is threadedly connected to the screw head 22, the screw head 22 moves axially back and forth along the fourth hole 24 and the fifth hole 25 under the drive of the adjusting screw 21. When the screw head 22 applies a horizontal pressure to the inner tube 2, the end of the inner tube 2 near the eyepiece will move along the direction of the pressure, and the second reset structure 27 will be compressed accordingly. The end of the inner tube 2 near the eyepiece will move horizontally left and right with the ball 11 as the fulcrum. At the same time, due to the existence of the waist-shaped hole and the pressing member, the inner tube 2 has a clear moving direction and range of movement. Therefore, the inner tube 2 avoids the phenomenon of deviation during the movement, thereby achieving precise adjustment. When the adjusting screw 21 is turned in the opposite direction, when the pressure of the screw head 22 on the inner tube 2 gradually decreases, since the second reset structure 27 has a reaction force on the inner tube 2, it will push the inner tube 2 to move in the opposite direction. At this time, the inner tube 2 continues to pivot with the ball 11 as the fulcrum until the position adjusted by the shooter is reached.

[0053] It should be noted here that after the ballistic adjustment or windage adjustment is completed, due to the reaction force of the pressing member on the inner tube 2, the reaction force further presses the first ball socket 8 against the ball 11. At the same time, since the second ball socket column 9 restricts the displacement of the ball 11, the ball 11 is in a static state relative to the second ball socket column 9. Therefore, the front end of the inner tube 2 will not move after receiving the reaction force of the pressing member, but is in a tightened state under the action of the pressing member and the ball 11. Since the other end of the inner tube 2 is in a tightened state under the action of the adjustment mechanism, the inner tube 2 as a whole is in a tightened state inside the mirror body 1. This can effectively prevent the inner tube 2 from shifting after the telescopic sight completes the compensation adjustment, which is beneficial to reducing the possibility of parallax in the telescopic sight and improving the shooting accuracy.

[0054] In the above-mentioned ballistic adjustment assembly 18 and windage adjustment assembly 19, a sealing ring 28 is further included to prevent external impurities, such as water vapor, dust, snow, etc., from entering the telescopic sight and affecting the use of the telescopic sight.

[0055] In order to prevent the optical channel 4 and the beam splitter 5 from being easily affected by the external environment, in this embodiment, an object-side protective lens 29 is provided at one end of the optical channel 4 close to the object side, and an eyepiece-side protective lens 30 is provided at one end of the mirror body 1 on the eyepiece side to weaken the influence of the external environment on the use of the telescopic sight.

[0056] In order to facilitate the replacement of the object-side protective lens 29 and the maintenance of the beam splitter 5, in this embodiment, the object-side protective lens 29 can also be embedded in the lens frame 31, and then the lens frame 31 with the object-side protective lens 29 embedded is connected to the mirror body 1. The connection method can be, but is not limited to, the way of adhesive. Similarly, the eyepiece-side protective lens 30 can be directly connected to the mirror body 1 or can also be connected to the mirror body 1 by means of the lens frame 31, which is not limited here.

[0057] In this embodiment, the telescopic sight further includes a battery pack 32 electrically connected to the light source group 6 and used to supply power to the light source group 6, and a button group for adjusting the brightness of the light source group 6. The battery pack 36 can be a button battery, a solar battery, or a rechargeable battery.
