Description

Technical Field

[0001] The present application belongs to the field of aiming devices, and in particular to a pistol dot sight. Background Art

[0002] There are two main types of reflex sights on the market, open and closed. Generally speaking, users tend to use open sights during hunting. One of the important reasons is that users hope to see a wider range through the sight so that they can quickly capture the position of the prey and effectively grasp the shooting opportunity. The cross-sectional shape of the open sight window is square, which can increase the cross-sectional area of ​​the light channel, thus providing users with a larger viewing field of view. Therefore, the open sight can meet the needs of users well. However, the open sight is also a sight whose optical path is exposed to the external environment. Impurities in the external environment, such as snow, dust, water, etc., can easily have an adverse effect on the stability of the optical path, making the sight prone to parallax, which in turn affects the user's aiming and shooting.

[0003] While ensuring that the cross-sectional area of ​​the optical channel is large, in order to avoid parallax caused by the influence of the external environment on the optical path, technical personnel in this field have made further improvements, such as the application number US20190277600A1 and the name of the reflective sight. Although this invention patent can, to a certain extent, ensure a larger cross-sectional area of ​​the optical channel and avoid the influence of the external environment on the optical path, adding a protrusion to the outer periphery of the front end of the inner tube will not only further increase the weight of the sight, but also make the structure of the sight complicated, thereby increasing the possibility of errors in the compensation adjustment, which is not conducive to reducing the parallax of the sight.

[0030] The specific implementation of this application is described in more detail below in conjunction with specific embodiments:

[0031] See also Figure 1 A pistol dot sight comprises a scope body 1, an inner tube 3 and an outer tube 12. The scope body 1 is provided with an inner cavity 2 which passes through the scope body 1 along its axial direction. The inner tube 3 and the outer tube 12 are both installed in the inner cavity 2, and the inner tube 3 can be pivotally fixed to the outer tube 12.

[0032] See also Figure 2 , Figure 4 In this embodiment, the outer tube 12 is provided with a support portion 13 that can cooperate with the inner tube 3, and the support portion 13 can be but is not limited to a circumferential groove. The inner cavity 2 is provided with four evenly arranged threaded holes 171, and the outer tube 12 is also provided with a first through hole 172 corresponding to the threaded hole 171. The locking screw 16 passes through the first through hole 172 and is threadedly connected with the threaded hole 171, so that the outer tube 12 can be fixedly connected to the inner cavity 2. Specifically, the outer tube 12 includes a front tube frame 121 and a rear tube frame 122, and the front tube frame 121 and the rear tube frame 122 are each provided with a partial circumferential groove. The locking screw 16 passes through the through hole 172 to fix the front tube frame 121 and the rear tube frame 122 to the inner cavity 2 of the mirror body 1, which is used to support the pivoting part 7 and cooperate with the pivoting part 7 to pivot.

[0033] In this embodiment, the cross-sectional shape of the inner tube 3 and the cross-sectional shape of the mirror body 1 are both rectangular. In some other embodiments, the cross-sectional shape of the inner tube 3 and the cross-sectional shape of the mirror body 1 can also be triangular, quasi-rectangular or other polygonal shapes.

[0034] See also Figure 1 , an optical channel 4 is arranged inside the inner tube 3, at least one optical element or lens, such as a dichroic mirror 5, is arranged along the end of the optical channel 4 close to the object side, and a light source group 6 is arranged at the end close to the eye side, and the light source group 6 is used to emit a light beam of a preset wavelength to the dichroic mirror 5, and the dichroic mirror 5 is used to reflect the light beam to the person, so as to assist the user to achieve aiming. It should be noted here that the color of the light beam can be red, green, yellow, etc., which is not limited here; the dichroic mirror 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. The light source group 6 is arranged on the bottom surface of the inner tube 3 close to the eye side, and the light source group 6 at least includes a light-emitting component that can emit a light beam of a preset wavelength to the dichroic mirror 5, such as an LED (Light-Emitting Diode), a resonant cavity light-emitting diode, etc.;

[0035] Among them, the battery pack 30 that provides power to the light source group 6 is arranged on the surface of the mirror body 1 and is electrically connected to the light source group 6. The light beam emitted by the light emitting element in the light source group 6 is projected on the surface of the diffraction mirror 5 at an angle along the path of the light beam A, and then the light beam is reflected by the diffraction mirror 5 and propagates along the light beam B in the light channel 4, and then reflected to the user's eye C, at which time the eye C can see an aiming mark at infinity. Therefore, when the user observes the target through the sight, the user places the aiming mark formed by the light beam on the diffraction mirror 5 on the target, so that the target, the aiming mark and the human eye form a straight line, that is, the shooting technique "three points and one line" well known in the art, thereby completing the shooting aiming. In addition, the aiming mark shape displayed by the light beam emitted by the light source element to the diffraction mirror 5 can be a mark line of other shapes in addition to a dot shape, such as an illuminated cross or any other suitable shape.

[0036] Since the process from the bullet being fired to hitting the target is a non-ideal state, it is affected by many factors, such as the shooter's distance from the target, the trajectory of the bullet or the shot, the type of weapon, the barrel, wind resistance, humidity, temperature, etc. Therefore, in order to improve the user's shooting accuracy, the present invention also includes an adjustment mechanism, and the user can provide compensation for the scope according to different shooting environments to maintain a high hit rate. Please refer to Figure 1 , Figure 2 as well as Figure 3 In the present embodiment, the adjusting mechanism is arranged at the end of the inner tube 3 close to the target, and the adjusting mechanism includes two adjusting components, namely a trajectory adjusting component 18 and a windage adjusting component 19. The trajectory adjusting component 18 is arranged on one side of the inner tube 3 along the vertical direction, and the windage adjusting component 19 is arranged on one side of the inner tube 3 along the horizontal direction; the adjusting mechanism also includes two resetting mechanisms respectively arranged corresponding to the trajectory adjusting component 18 and the windage adjusting component 19, which are a first resetting structure 26 and a second resetting structure 27.

[0037] Specifically, the ballistic adjustment component 18 is arranged on the top of the sight and abuts against the inner tube 3, and the corresponding first reset structure 26 is arranged inside the scope body 1 and below the inner tube 3; the windage adjustment component 19 is arranged on either side of the two sides of the sight and abuts against the inner tube 3, 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 18 and the windage adjustment component 19 include a nail sleeve 20, an adjustment nail 21, and a nail head 22. The mirror body 1 is provided with a first hole 23 and a second hole 24 provided at the bottom of the first hole 23 and connected to the inner cavity 2. The adjustment nail 21 is rotatably arranged in the first hole 23. The nail sleeve 20 is connected to the first hole 23 and together with the first hole 23 limits the axial movement of the adjustment nail 21 along the first hole 23. The adjustment nail 21 is provided with a third hole 25, and the third hole 25 is a threaded hole. One end of the nail head 22 can be threadedly matched with the third hole 25.

[0039] In this embodiment, the second 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 third hole 25, the second hole 24 is a non-circular hole, and the nail head 22 is restricted from rotating relative to the third hole 25, and the nail head 22 is threadedly connected to the second hole 24;

[0041] Since the end of the inner tube 3 close to the target can be driven by the adjustment mechanism, and the other end of the inner tube 3 can also be pivotally mounted on the inner circumference of the outer tube 12, the end of the inner tube 3 away from the target must also move accordingly, otherwise the purpose of compensation adjustment cannot be achieved.

[0042] See also Figure 1 , Figure 2 , Figure 5 as well as Figure 7 and Figure 8The inner tube 3 is divided into a front part and a rear part. The front part is the pivot part 7, and the rear part is the part of the inner tube 3 other than the pivot part 7, which is used to receive the force applied by the adjustment mechanism. The cross-sectional shape of the inner tube 3 can be roughly rectangular or square, wherein the center of the pivot part 7 is point O. The outer periphery of the pivot part 7 has a first plane 31, a second plane 32, a third plane 33 and a fourth plane 34. The length direction of the pivot part 7 is the OX direction, the width direction is the OY direction, and the height direction is the OZ direction. In the OZ direction, the vertical distance from the center point O of the pivot part 7 to the first plane 31 and the fourth plane 34 of the pivot part 7 is slightly greater than the vertical distance from the center point O of the pivot part 7 to the outer wall surface of the rear part of the inner tube 3. The purpose of this is to ensure that the inner tube 3 has sufficient movement space during the process of adjusting the trajectory or windage. Similarly, in the OY and OZ directions, the vertical distance from the center of the pivot part 7 to the inner wall surface of the pivot part 7 is slightly greater than the vertical distance from the center of the pivot part 7 to the inner wall surface of the rear part of the inner tube 3. The purpose of this is to increase the window of the sight, which is conducive to increasing the amount of light passing through, ensuring that the user's viewing field of view is larger, and helping the user to quickly find the target position. The first plane 31 intersects with the second plane 32 at P1, the first plane 31 intersects with the third plane 33 at P2, the third plane 33 intersects with the fourth plane 34 at P3, and the second plane 32 intersects with the fourth plane 34 at P4. The pivot portion is transitioned by a continuous smooth surface at the junction of two adjacent planes along its length direction, and the distance from each point on the smooth surface to the center O of the pivot portion is the same. The smooth surface includes at least a first smooth surface 8, a fourth smooth surface 11, or at least a second smooth surface 9, a third smooth surface 10, wherein the first smooth surface 8 is formed at the lower left side of the intersection P1, the second smooth surface 9 is formed at the lower right side of the intersection P2, the third smooth surface 10 is formed at the upper left side of the intersection P4, and the fourth smooth surface 11 is formed at the upper right side of the intersection P3; in this embodiment, the pivot portion 7 has a first smooth surface 8, a second smooth surface 9, a third smooth surface 10 and a fourth plane 11.

[0043] See also Figure 2 , Figure 5 and Figure 6, the inner surface of the outer tube 12 is provided with a circumferential groove, and the circumferential groove has a center point O', which coincides with the center point O of the pivot part 7. The length direction of the circumferential groove is the O'X direction, wherein the length of the circumferential groove is the same as the length of the pivot part 7, and the smooth curved surface is arranged toward the support part, so during installation, the end away from the pivot part 7 first passes through the front tube frame 121, so that the smooth curved surface part abuts against the circumferential groove of the front tube frame 121, and finally covers the rear tube frame 122, and the other part of the smooth curved surface abuts against the circumferential groove, so that the inner tube 3 can be pivotally installed on the outer tube 12. Since the smooth curved surface is in sliding contact with the corresponding circumferential groove surface and has the same center point and the same radius R as the circumferential groove, when the adjustment mechanism performs compensation adjustment on the sight, the adjustment mechanism applies corresponding pressure in the vertical and horizontal directions of the inner tube 3, and the inner tube 3 will tilt up and down or left and right relative to the outer tube 12 with the pivot part 7 as the fulcrum. At this time, the position of the light beam emitted by the light source on the target changes.

[0044] In some embodiments, see Fig. 9 , Fig.10 The circumferential groove at least includes a first groove segment 131 and a fourth groove segment 134 corresponding to the first smooth curved surface 8 and the fourth smooth curved surface 11, or a second groove segment 132 and a third groove segment 133 corresponding to the second smooth curved surface 9 and the third smooth curved surface 10. The first smooth curved surface 8, the second smooth curved surface 9, the third smooth curved surface 10 and the fourth smooth curved surface 11 are respectively arranged toward the first groove segment 131, the second groove segment 132, the third groove segment 133 and the fourth groove segment 134, and are in sliding contact.

[0045] See also Figure 4In some embodiments, since the pivoting of the pivoting part 7 body and the circumferential groove is the cooperation between rigid elements, the cohesion between the two elements is weak during the pivoting process, resulting in poor smoothness during the adjustment process. Therefore, in order to improve the cohesion between the two elements and make the cooperation between the two elements smoother, in some embodiments, a retaining pad 15 is further provided between the front tube frame 121 and the rear tube frame 122, so that the inner periphery of the front tube frame 121, the rear tube frame 122 and the retaining pad 15 constitute the support part 13, and the retaining pad 15 can be but not limited to a rubber pad. The retaining pad 15 is provided with a second through hole 173 corresponding to the threaded hole 171 and the first through hole 172, and the locking screw 16 passes through the first through hole 172, the second through hole 173 and is threadedly connected with the threaded hole 171, so that the front tube frame 121, the rear tube frame 122 and the retaining pad 15 are installed in the inner cavity 2 of the sight along the axial direction of the scope body 1. In this embodiment, the number of the threaded hole 171, the first through hole 172 and the second through hole 173 are all four. Since the retaining pad 15 disposed between the front tube frame 121 and the rear tube frame 122 is fixed to the inner cavity 2 as an integral component by the locking screw 16, its degree of freedom is greatly limited. When the smooth curved surface moves, the influence of the restoring degree of freedom of the retaining pad 15 is small, so the adjustment deviation can be controlled within a small range. In addition, since the outer tube 12 is composed of the front tube frame 121 and the rear tube frame 122, there are inevitably gaps. Therefore, the provision of the retaining pad 15 is also conducive to preventing moisture from entering the inner tube 3 and affecting the user's aiming, making the scope more applicable.

[0046] When adjusting the trajectory or windage, the shooter can use a wrench or other tool to screw the adjusting pin 21, so that the adjusting pin 21 rotates in the first 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 second hole 24 and the third hole 25 under the drive of the adjusting pin 21. When the pin head 22 applies a vertical downward or horizontal pressure to the inner tube 3, the end of the inner tube 3 close to the target moves along the direction of the pressure with the pivot 7 as the fulcrum. At this time, the smooth curved surface slides on the surface of the circumferential groove, so that the inner tube 3 tilts relative to the outer tube 12. As the pressure continues The force applied is applied, and the reset structure is compressed as a result; when the adjusting pin 21 is twisted in the opposite direction, the adjusting pin 21 also moves away from the inner tube 3 in the opposite direction of its axial direction. At this time, due to the elastic member restoring the degree of freedom, the elastic member will push the inner tube 3 in the direction of the thrust until the light beam emitted by the light source group 6 is adjusted to the user's target position, thereby completing the trajectory or windage adjustment; at the same time, driven by the adjusting mechanism, the smooth curved surface of the inner tube 3 pivots in the circumferential groove, and the surface of the smooth curved surface is in sliding contact with the inner periphery of the retaining pad 15. Due to the yielding effect of the retaining pad 15, the sliding of the smooth curved surface in the circumferential groove is smoother, thus avoiding slipping.

[0047] The adjustment mechanism also includes a sealing ring, 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;

[0048] See also Figure 1 In some embodiments, in order to prevent the optical channel 4 and the light analyzer 5 from being easily affected by the external environment, an object side protection mirror 29 is provided at the object side end of the scope body 1, and an eye side protection mirror 28 is provided at the eye side end of the scope body 1 to reduce the adverse effects of the external environment on the use of the sight.

[0049] 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, and then the lens frame 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 28 can be directly connected to the lens body 1, or it can be connected to the lens body 1 in the form of a lens frame, which is not limited here.

[0050] See also Figure 1 In some embodiments, the sight further includes a battery pack 30 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. The battery pack 30 can be a button battery, a solar cell, or a rechargeable battery.

[0051] Through the above design, the present invention has at least the following beneficial technical effects:

[0052] First, the smooth curved surface in the present invention is formed by machining the main body of the pivoting part 7 and is located at the intersection of two adjacent planes of the pivoting part 7. Driven by the adjustment mechanism, the smooth curved surface is in sliding contact with the surface of the support part 13, and the main body of the pivoting part 7 can directly pivot with the support part 13, and the sight can be compensated and adjusted without adding other pivoting mechanisms on the outer peripheral plane of the pivoting part 7. Therefore, the present application can effectively reduce the complexity of the sight in the compensation adjustment process, reduce the deviation in the compensation adjustment process, and then ensure the stability of the inner tube 3 in the compensation adjustment process, so as to reduce the parallax of the sight and improve the accuracy of shooting.

[0053] Second, since the first smooth curved surface 8, the second smooth curved surface 9, the third smooth curved surface 10 and the fourth smooth curved surface 11 are respectively arranged at the left oblique lower part of P1, the right oblique lower part of P2, the left oblique upper part of P4 and the right oblique upper part of P3, that is, no other mechanism higher than the outer periphery of the pivoting part 7 is added, the width and height of the pivoting part 7 determine the size of the outer tube 12, and further determine the size of the scope body 1. Compared with the prior art, the scope in the present application is smaller in size and more compact in structure.

[0054] Since the smooth curved surface is formed by cutting part of the pivot part 7 body, and a circumferential groove is arranged on the inner periphery of the outer tube 12, the material required for the sight can be further reduced. Therefore, compared with the prior art, the present application can also reduce the total weight of the sight, which is beneficial to reduce the burden on users and save production costs.

[0055] The above are only preferred embodiments of the present invention, and only specifically describe the technical principles of the present invention. These descriptions are only for explaining the principles of the present invention and cannot be interpreted as limiting the scope of protection of the present invention in any way. Based on the explanations here, any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention, and other specific implementations of the present invention that can be associated with by technicians in this field without creative labor, should be included in the scope of protection of the present invention.
