Description

Technical Field

[0001] The present application belongs to the technical field of aiming devices, and in particular, relates to a dot-type aiming scope with a square window. Background Art

[0002] Reflex sights are widely used because of their relatively simple optical system, small size and portability. The main principle is that light from a light source with a specific wavelength is irradiated along the optical path to a coated dichroic mirror, which then reflects the light and enters the shooter's eye, thus completing the aiming.

[0003] In order to ensure that the sighting field of the telescope is relatively large and avoid the influence of the external environment on the optical path and cause parallax, ordinary technicians in this field often set the optical path system on a square inner tube, and then install the inner tube inside the telescope body, so as to effectively avoid the influence of the external environment. For example, the invention with publication number CN115265275A and name "sight" includes a square tube and a telescope body, a light source group and a light analyzer for reflecting light are arranged inside the square tube, a flange is arranged on the outer periphery of the front end of the square inner tube, an elastic ring is arranged on the outer periphery of the front end of the telescope body, and the elastic ring is provided with a groove that can cooperate with the flange. The inner tube responds to the force applied by the adjustment mechanism and rotates around the linear fulcrum formed by the flange under the constraint of the elastic ring, thereby completing the adjustment. However, after the adjustment of the telescope adopting this structure is completed, due to the influence of the elastic ring restoring the degree of freedom, the inner tube will inevitably have a certain displacement, which will easily cause the telescope to produce parallax, further affecting the accuracy of shooting targets.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0030] Sights are often installed on firearms to improve aiming accuracy and reduce shooting difficulty. In this application, "target side" means the end of the sight that is close to the shooter during actual operation, and "object side" means the end of the sight that is close to the target during actual operation, that is, the end away from the shooter.

[0031] The specific implementation of this application is described in more detail below in conjunction with specific embodiments:

[0032] See also Figure 1 , Figure 2 , Figure 5 The present application provides a point-type sight with a square window, comprising a scope body 1, an inner tube 2, and an adjustment mechanism. An inner cavity 3 is provided inside the scope body 1 and passes through the scope body 1 along its axial direction. The inner tube 2 is installed in the inner cavity 3. The cross-sectional shape of the inner tube 2 is the same as the cross-sectional shape of the scope body 1. In this embodiment, the cross-sectional shape of the inner tube 2 and the cross-sectional shape of the scope body 1 are both square.

[0033] In some embodiments, the cross-sectional shape of the inner tube 2 and the cross-sectional shape of the mirror body 1 are both triangles or other polygons.

[0034] The inner tube 2 is provided with an optical channel 4, and a light analyzer 5 is provided at one end of the inner tube 2 close to the object along the optical channel 4, and a light source group 6 is provided at one end close to the eye, and the light source group 6 is used to emit a light beam of a preset wavelength to the light analyzer 5, and the light analyzer 5 is used to reflect the light beam to the human eye, so as to achieve aiming. It should be noted that the color of the light beam can be red, green, yellow, etc., which is not limited here; the light analyzer 5 is a lens with a certain thickness, such as a glued lens or other types of lenses, and the surface of the lens is usually coated with one or more layers of reflective film with a certain transmittance, such as a red film, a green film, etc.

[0035] The light source group 6 is arranged on the bottom surface of the inner tube 2 near the end of the eyepiece, and the light source group 6 at least includes a light-emitting component capable of emitting a light beam of preset wavelength to the diffraction mirror 5, such as an LED (Light-Emitting Diode), etc.; therefore, when the adjustment mechanism drives the inner tube 2, the position of the light-emitting component is in a stationary state relative to the inner tube 2, so the position of the light beam irradiated on the diffraction mirror 5 also changes, and the position of the light beam observed by the shooter also changes accordingly, thereby achieving the effect of trajectory compensation or windage compensation.

[0036] The adjustment mechanism includes two adjustment components, which are a trajectory adjustment component 18 and a windage adjustment component 19. The trajectory adjustment component 18 is arranged on one side of the inner tube 2 in the vertical direction, and the windage adjustment component 19 is arranged on one side of the inner tube 2 in the horizontal direction; the adjustment mechanism also includes two reset mechanisms respectively arranged corresponding to the trajectory adjustment component 18 and the windage adjustment component 19, which are a first reset structure 26 and a second reset structure 27.

[0037] Specifically, the adjustment mechanism is arranged at one end of the sight close to the target. In the present embodiment, the ballistic adjustment component 18 is arranged at the top position of the sight, and the corresponding first reset structure 26 is arranged inside the scope body 1 and below the inner tube 2; the windage adjustment component 19 is arranged on either side of the two sides of the sight, and the corresponding second reset structure 27 is arranged on the other side; wherein the first reset structure 26 and the second reset structure 27 can be but not limited to springs or springs.

[0038] The trajectory adjustment component and the windage adjustment component include the nail sleeve 20, the adjustment nail 21, and the nail 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 connected to the inner cavity. The adjustment nail 21 is rotatably arranged in the third hole 23. The nail sleeve 20 is connected to the third hole 23 and together with the third hole 23 limits the axial movement of the adjustment nail 21 along the third hole 23. The adjustment nail 21 is provided with a fifth hole 25, and the fifth hole 25 is a threaded hole. One end of the nail head 22 can be threadedly matched with the fifth hole 25.

[0039] It should be noted that the fourth hole 24 may be, but is not limited to, a non-circular hole.

[0040] In some embodiments, the end of the nail head 22 is inserted into the fifth hole 25 , the fourth hole 24 is a non-circular hole and limits the rotation of the nail head 22 relative to the fifth hole 25 , and the nail head 22 is threadedly connected to the fourth hole 24 .

[0041] See also Figure 2-6 The accommodating portion includes at least a first ball socket column 7 and a first ball socket 8, the supporting portion includes a second ball socket column 9 and a second ball socket 10, the fulcrum portion includes at least a ball 11, the first ball socket 8 and the second ball socket 10 are at least partially in contact with the ball 11, the ball 11 provides a pivot fulcrum for the first ball socket column 7, and the second ball socket 10 provides support for the ball 11.

[0042] It should be noted that the ball 11 may be, but is not limited to, a steel ball, and any ball with a spherical or partially spherical fulcrum falls within the protection scope of the present invention.

[0043] The first ball socket column 7 is arranged on the lower surface of the outer circumference of the inner tube 2, and the second ball socket column 9 is arranged on the lower surface of the inner circumference 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. The second ball socket column 9 is provided with a second ball socket 10 at one end close to the first ball socket column 7, and the ball 11 is arranged between the first ball socket column 7 and the second ball socket column 9.

[0044] Specifically, the first ball socket column 7 is integrally formed with the inner tube 2, but a detachable connection or a fixed connection may also be used, such as a threaded connection, a disassembly connection, or an adhesive connection. In order 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 mirror body 1. More specifically, the second ball socket column 9 is also provided with two connecting ears 12, and the connecting ears 12 are provided with a first threaded hole 121. The bottom surface of the mirror body 1 close to the object side is provided with a groove 13, and 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 interior of the mirror body 1 through the first hole 14, the assembler can use an adapted locking screw or other locking member to detachably install the second ball socket column 9 on the mirror body 1 through the first threaded hole 121 and the second threaded hole 131. It should be noted here that the detachable installation can be a bonding, plug-in connection, etc.

[0045] 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 distance from each point on the ball socket surface of the first ball socket 8 and the second ball socket 10 to the center of the ball 11 is the same as the radius of the ball 11, so that the first ball socket 8 and the ball 11 have good pivotability, making the adjustment smoother and more precise; in addition, it should be noted that when performing ballistic adjustment, the inner tube 2 will tilt up and down relative to the mirror body 1 with the ball 11 as the fulcrum under the drive of the ballistic adjustment component 18, which means that the first ball socket column 7 tilts back and forth on the ball 11. Specifically, Figure 7 As 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 shortened. In order to avoid 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 trajectory adjustment. Therefore, in this embodiment, the calibers of the first ball socket 8 and the second ball socket 10 are both smaller than the diameter of the ball 11.

[0046] In some embodiments, the caliber of the first ball socket 8 is greater than or equal to the diameter of the ball 11, while the caliber of the second ball socket 10 is smaller than the diameter of the ball 11; or, the caliber of the first ball socket 8 is smaller than the diameter of the ball 11, while the caliber of the second ball socket 10 is greater than or equal to the diameter of the ball 11.

[0047] In this embodiment, the inner tube 2 tilts up and down relative to the mirror body 1 with the ball 11 as a fulcrum under the drive of the trajectory adjustment component 18. However, 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 state of dynamic imbalance during movement, and the movement direction is easily deviated, and the expected adjustment effect cannot be achieved. In order to make the inner tube 2 in a state of dynamic balance when performing trajectory adjustment or windage adjustment, the inner tube 2 is provided with a clamping member on both sides. After the clamping member passes through the countersunk hole 15 on the mirror body 1, it abuts against the second hole 16 set on the side of the inner tube 2. The clamping member includes at least a shaft pin 17, which maintains the dynamic balance of the inner tube 2 during the trajectory adjustment or the trajectory adjustment process 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.

[0048] It should be noted that the second hole 16 may be, but is not limited to, a waist-shaped hole, and may also be other non-circular holes, special-shaped holes, etc.

[0049] See also Figure 8 In this embodiment, the second hole 16 is a waist-shaped hole, and the slot 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 slide 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, so that the inner tube 2 can be prevented 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 the windage adjustment, the second hole 16 also moves synchronously. In order to avoid the pressing member blocking the movement of the inner tube 2 during the windage adjustment process, the length L of the waist-shaped hole can be determined according to the actual windage adjustment range. The purpose of this design is to provide the inner tube 2 with sufficient movement space during the windage adjustment process.

[0050] When the above-mentioned sight is adjusted for ballistics, the shooter can use a tool such as a wrench to screw the adjusting pin 21, so that the adjusting pin 21 rotates in the third hole 23. Since the adjusting pin 21 and the pin head 22 are threadedly connected, the pin head 22 moves axially back and forth along the fourth hole 24 and the fifth hole 25 under the drive of the adjusting pin 21. When the pin head 22 applies a vertical pressure to the inner tube 2, the end of the inner tube 2 close to the target will move along the direction of the pressure, and the first reset structure 26 is compressed, and the end of the inner tube 2 close to the object The inner tube 2 is tilted up and down with the ball 11 as the fulcrum. At the same time, due to the presence of the waist-shaped hole and the clamping piece, the inner tube 2 has a clear moving direction and moving range, so the inner tube 2 avoids deviation during the movement, thereby achieving precise adjustment; when the adjusting nail 21 is turned in the opposite direction, the pressure of the nail 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 it reaches the position adjusted by the shooter.

[0051] When the above-mentioned sight is adjusted for windage, the shooter can use a tool such as a wrench to screw the adjusting pin 21, so that the adjusting pin 21 rotates in the third hole 23. Since the adjusting pin 21 and the pin head 22 are threadedly connected, the pin head 22 moves axially back and forth along the fourth hole 24 and the fifth hole 25 under the drive of the adjusting pin 21. When the pin head 22 applies a horizontal pressure to the inner tube 2, the end of the inner tube 2 close to the sight will move along the direction of the pressure, and the second reset structure 27 is compressed, and the end of the inner tube 2 close to the sight The inner tube 2 then moves horizontally left and right with the ball 11 as the fulcrum. At the same time, due to the presence of the waist-shaped hole and the clamping piece, the inner tube 2 has a clear moving direction and moving range, so the inner tube 2 avoids deviation during the movement, thereby achieving precise adjustment; when the adjusting nail 21 is turned in the opposite direction, the pressure of the nail 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 it reaches the position adjusted by the shooter.

[0052] It should be noted here that after completing the ballistic adjustment or windage adjustment, since the clamping piece has a reaction force on the inner tube 2, the reaction force further causes the first ball socket 8 to press the ball 11 tightly. At the same time, since the second ball socket column 9 limits the displacement of the ball 11, the ball 11 is in a stationary state relative to the second ball socket column 9. Therefore, the front end of the inner tube 2 does not move after being subjected to the reaction force of the clamping piece, but is in a pressed state under the action of the clamping piece and the ball 11. Since the other end of the inner tube 2 is in a pressed state under the action of the adjustment mechanism, the inner tube 2 as a whole is in a pressed state inside the scope body 1. This can effectively prevent the inner tube 2 of the sight from shifting after the compensation adjustment is completed, which is beneficial to reduce the possibility of parallax in the sight and improve shooting accuracy.

[0053] The above-mentioned trajectory adjustment component 18 and windage adjustment component 19 also include a sealing ring 28, which is used to prevent external impurities, such as water vapor, dust, snow, etc., from entering the interior of the sight and affecting the use of the sight.

[0054] In order to prevent the optical channel 4 and the light analyzer 5 from being easily affected by the external environment, in this embodiment, an object side protection mirror 29 is arranged along the optical channel 4 close to the object side end, and an eye side protection mirror 30 is arranged at the eye side end of the scope body 1 to reduce the influence of the external environment on the use of the sight.

[0055] In order to facilitate the replacement of the object side protective lens 29 and the maintenance of the light analyzer 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 embedded with the object side protective lens 29 is connected to the lens body 1, and the connection method can be but not limited to the method of gluing. Similarly, the eye side protective lens 30 can be directly connected to the lens body 1, or can be connected to the lens body 1 in the form of a lens frame 31, which is not limited here.

[0056] In this embodiment, the sight further includes a battery pack 32 electrically connected to the light source group 6 and used to power the light source group 6, and a key group for adjusting the brightness of the light source group 6.
