Description

Technical Field

[0001] The present invention relates to the technical field of aiming devices, and in particular to an aiming device capable of instantly switching magnifications. Background Art

[0002] At present, in order to take into account both close-range and long-range aiming and shooting, the conventional practice is to use a red dot sight and a telescopic sight with a magnification in combination, and install the telescopic sight on the target side of the red dot sight by flipping the bracket. When the telescopic sight is needed, the bracket is flipped to switch it to the use position for long-range aiming or observation. When the telescopic sight is not needed, the bracket is flipped to switch it to a position that does not hinder the shooter's aiming, that is, the storage position, and the red dot sight can be used for close-range aiming. Although this combination can take into account the needs of long and short distance aiming, it is still inconvenient in installation and carrying because it is a combination of two sights. For example, two sights need to be installed when used. In this regard, U.S. Patent No. 8151509B2 discloses a sight with switchable magnification, which switches the magnification between 1x (equivalent to a red dot sight) and 4x (equivalent to a telescopic sight) through a sight that can instantly switch the magnification, and adjusts the trajectory and windage through an external adjustment mechanism. However, since this structure adopts an external adjustment mechanism, it is larger in size and heavier in weight, making it inconvenient to use and carry.

[0003] Therefore, it is necessary to improve the existing sights. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a lightweight sighting device which can switch magnification instantly, can meet the needs of long and short distance aiming, and is convenient to install and carry, and easy to operate.

[0005] As for a sight with instant magnification switching, the technical solution adopted by the present invention is: a sight with instant magnification switching, comprising a shell and an internal adjustment mechanism installed on the shell, a main optical path is provided inside the shell, and an objective lens group, a prism group and an eyepiece group are provided inside the shell in sequence along the main optical path from the object side to the eye side, wherein a magnification group is provided inside the objective lens group, the prism group is provided with a division center, and the division center is arranged on the first focal plane of the objective lens group, the prism group is also provided with a connecting end and an adjustment end opposite thereto, the connecting end is hingedly connected to the shell, the adjustment end is connected to the internal adjustment mechanism, the internal adjustment mechanism can act on the adjustment end to drive the prism group to move around the connecting end, the magnification group is provided with a low-magnification optical path and a high-magnification optical path, when the low-magnification optical path is aligned with the main optical path, the magnification of the sight is low, and when the high-magnification optical path is aligned with the main optical path, the magnification of the sight is high.

[0006] Compared with the prior art, the above-mentioned sight with instant magnification switching instantaneously switches the magnification through a variable magnification group to meet the requirements of long and short-distance shooting. At the same time, the internal adjustment mechanism is used to adjust the trajectory and windage. The internal adjustment mechanism is small in size and easy to install, so that the size of the sight can be reduced, the weight can be reduced, and it is very convenient to use and carry.

[0007] Further, the connecting end is a ball head, a ball socket matching the ball head is arranged inside the housing, and the ball head is hinged to the ball socket.

[0008] Further, the variable magnification group includes a flipping body and two rotating shafts. The flipping body is provided with three pairs of opposite planes. The two rotating shafts are respectively fixed on one pair of opposite planes, and the center lines of the two rotating shafts are aligned. The low-power optical path and the high-power optical path are respectively arranged on the remaining two pairs of opposite planes. The center lines of the rotating shafts, the low-power optical path and the high-power optical path are perpendicular to each other in pairs. The rotating shafts are rotatably connected to the housing, and the center line of the rotating shaft is perpendicular to the main optical path.

[0009] Further, the sight further includes a first adjusting screw and an elastic member. The first adjusting screw is threadedly connected to the housing, and the center line of the first adjusting screw is parallel to the center line of the rotating shaft. One end of the first adjusting screw abuts against one of the rotating shafts. The elastic member is sleeved on the other rotating shaft, and both ends of the elastic member respectively abut against the housing and the flipping body.

[0010] Further, the sight further includes a second adjusting screw. The second adjusting screw is threadedly connected to the housing, and the second adjusting screw extends out of the inner wall of the housing. The flipping body is provided with a protrusion facing outward. When the low-power optical path is aligned with the main optical path, the protrusion abuts against the second adjusting screw.

[0011] Further, the sight further includes a handwheel. The handwheel is fixedly connected to one of the rotating shafts, and when the handwheel rotates, it can drive the rotating shaft to rotate, thereby driving the flipping body to rotate synchronously.

[0012] Further, the housing is provided with a telescopic convex portion facing the handwheel. The outer surface of the handwheel is provided with two first concave portions and a second concave portion distributed at intervals. When the low-power optical path is aligned with the main optical path, the convex portion abuts against the inner wall of the first concave portion. When the high-power optical path is aligned with the main optical path, the convex portion abuts against the inner wall of the second concave portion.

[0013] Further, when the convex portion abuts against the first concave portion, the convex portion abuts against the inner side wall of the first concave portion and applies a moment to the flipping body, so that the flipping body abuts against the housing and at the same time has a tendency to rotate around the rotating shaft.

[0021] It should be noted that the "first", "second" and similar terms used in the present invention do not indicate any order, quantity or importance, but are only used to distinguish different components. The "upper", "lower", "left", "right", "front", "rear", "top", "bottom", etc. used in the present invention are only used to represent relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0022] As introduced in the background art section, the existing aiming devices use external adjustment mechanisms to adjust the ballistic and windage parameters, resulting in large aiming device volumes, heavy weights, and inconvenience in use and carrying. Therefore, it is necessary to improve the existing aiming devices.

[0023] To better describe the technical solutions of the present invention, reference will be made to Figures 1 to 6 describe an embodiment of an aiming device with instant magnification switching provided by the present invention.

[0024] Reference Figure 1 and Figure 2, A sight with instant magnification switching provided in this embodiment includes a housing 1 and an internal adjustment mechanism 2 installed on the housing 1. A main optical path 11 is provided inside the housing 1. An objective lens group 3, a prism group 4, and an eyepiece group 5 are sequentially arranged inside the housing 1 along the main optical path 11 from the object side to the eyepiece side. Among them, a variable magnification group 6 is provided inside the objective lens group 3. The prism group 4 has a reticle center, and the reticle center is set on the first focal plane of the objective lens group 3. One end of the prism group 4 is provided with a ball head 41, and a ball socket 12 matching the ball head 41 is provided on the inner wall of the housing 1. The ball head 41 is hinged to the ball socket 12. The other end of the prism group 4 opposite to the ball head 41 is an adjustment end 42, which is connected to the internal adjustment mechanism 2. The internal adjustment mechanism 2 can act on the adjustment end 42 to drive the prism group 4 to move around the ball head 41. The variable magnification group 6 is provided with a low-power optical path 61 and a high-power optical path 62. The low-power optical path 61 is provided with a corresponding lens group, and the high-power optical path 62 is a light passing hole. When the low-power optical path 61 is aligned with the main optical path 11, the magnification of the sight is low (as Figure 1 shown), and when the high-power optical path 62 is aligned with the main optical path 11, the magnification of the sight is high (as Figure 2 shown). It should be noted that the internal adjustment mechanism 2 can adopt an adjustment mechanism for a miniaturized sighting scope with the patent number CN207881567U, which includes a handwheel seat and an adjustment nail head. During use, the handwheel seat is fixed on the above-mentioned housing 1, and the adjustment nail head abuts against the adjustment end 42 of the prism group 4.

[0025] It can be seen that the above-mentioned sight with instant magnification switching instantaneously switches the magnification through the variable magnification group 6 to meet the requirements of long and short-range shooting. At the same time, the internal adjustment mechanism 2 is used for ballistic and windage adjustment. The internal adjustment mechanism 2 is small in volume and easy to install, so that the size of the sight can be reduced, the weight can be reduced, and it is very convenient to use and carry.

[0026] As Figures 3 to 6 shown, in order to facilitate instant magnification change, in this embodiment, the variable magnification group 6 includes a flipping body 63 and two rotating shafts 64. The flipping body 63 is provided with three pairs of opposite planes Ⅰ-Ⅰ, Ⅱ-Ⅱ, and Ⅲ-Ⅲ. The two rotating shafts 64 are respectively fixed on the Ⅰ-Ⅰ plane, and the center lines 641 of the two rotating shafts 64 are aligned. The low-power optical path 61 and the high-power optical path 62 are respectively arranged on the Ⅱ-Ⅱ plane and the Ⅲ-Ⅲ plane. The center line 641 of the rotating shaft 64, the low-power optical path 61, and the high-power optical path 62 are perpendicular to each other in pairs. The rotating shaft 64 is rotatably connected to the housing 1, and the center line 641 of the rotating shaft 64 is perpendicular to the main optical path 11. When the magnification needs to be switched, only the flipping body 63 needs to be rotated to align the optical path therein with the main optical path 11. For example, when switching from low power to high power, the flipping body 63 is rotated counterclockwise to make the low-power optical path 61 leave the main optical path 11 and the high-power optical path 62 aligned with the main optical path 11.

[0027] As Figure 4As shown in the figure, to facilitate the adjustment of the deviation between the optical path of the flipping body 63 and the main optical path 11 in the left-right direction, in this embodiment, the sighting device further includes a first adjusting screw 7 and an elastic member 8. The first adjusting screw 7 is threadedly connected to the housing 1, and the center line of the first adjusting screw 7 is parallel to the center line 641 of the rotating shaft 64. One end of the first adjusting screw 7 abuts against one of the rotating shafts 64. The elastic member 8 is sleeved on the other rotating shaft 64, and both ends of the elastic member 8 respectively abut against the housing 1 and the flipping body 63. When assembling the flipping body 63, if there is a deviation in the left-right direction between the low-magnification optical path 61 or the high-magnification optical path 62 of the flipping body 63 and the main optical path 11, the first adjusting screw 7 can be rotated to push the rotating shaft 64 to displace along its center line 641, thereby adjusting the deviation in the left-right direction between the optical path of the flipping body 63 and the main optical path 11. The elastic member 8 can make the first adjusting screw 7 and the rotating shaft 64 tightly abut against each other, eliminate the adjustment gap, and improve the adjustment accuracy.

[0028] As Figure 3 and Figure 4 shown in the figure, to facilitate the adjustment of the deviation between the optical path of the flipping body 63 and the main optical path 11 in the up-down direction, in this embodiment, the sighting device further includes a second adjusting screw 9. The second adjusting screw 9 is threadedly connected to the housing 1, and the second adjusting screw 9 extends out of the inner wall of the housing 1. The flipping body 63 is provided with a protrusion 631 facing outward. When the low-magnification optical path 61 is aligned with the main optical path 11, the protrusion 631 abuts against the second adjusting screw 9. When assembling the flipping body 63, if there is a deviation in the up-down direction between the low-magnification optical path 61 of the flipping body 63 and the main optical path 11, the second adjusting screw 9 can be rotated to push the flipping body 63 to flip by a certain angle around the rotating shaft 64, thereby adjusting the deviation in the up-down direction between the low-magnification optical path 61 of the flipping body 63 and the main optical path 11.

[0029] As Figure 3 and Figure 5 shown in the figure, to facilitate the flipping operation, in this embodiment, the sighting device further includes a handwheel 10. The handwheel 10 is fixedly connected to one of the rotating shafts 64, and when the handwheel 10 rotates, it can drive the rotating shaft 64 to rotate, thereby driving the flipping body 63 to rotate synchronously.

[0030] Further, in order to enable the flipping body 63 to be maintained at the magnification required by the user, in this embodiment, the housing 1 is provided with a chute 13 facing the handwheel 10. An abutting member 141 and a spring 142 are installed in the chute 13. One end of the abutting member 141 faces the handwheel 10, and the other end is connected to one end of the spring 142. The other end of the spring 142 abuts against the inner wall of the chute 13. Under the elastic force of the spring 142, the abutting member 141 abuts against the outer surface of the handwheel 10. The abutting member 141 and the spring 142 form a telescopic convex portion 14. Two first concave portions 101 and second concave portions 102 are spaced apart on the outer surface of the handwheel 10. When the low-magnification optical path 61 is aligned with the main optical path 11, the convex portion 14 abuts against the inner wall of the first concave portion 101. When the high-magnification optical path 62 is aligned with the main optical path 11, the convex portion 14 abuts against the inner wall of the second concave portion 102. By relying on the convex portion 14 to abut against the handwheel 10, the handwheel 10 is prevented from rotating after reaching the predetermined position, thereby ensuring that the flipping body 63 is maintained at the magnification required by the user.

[0031] In order to further enhance the stability of the flipping body 63 when it is at a low magnification, in this embodiment, when the convex portion 14 abuts against the first concave portion 101, the convex portion 14 abuts against the inner side wall of the first concave portion 101 and applies a moment to the flipping body 63, so that the flipping body 63 not only abuts against the housing 1 but also has a tendency to rotate around the rotation shaft 64. Specifically, Figure 3 The shown sight is in the low-magnification state. In this state, the convex portion 14 abuts against the outer surface of the handwheel 10. The convex portion 14 abuts against an inner side wall of the first concave portion 101 and applies a force F to the handwheel 10. The action line of the force F deviates from the rotation axis (i.e., the center line 641) of the handwheel 10 and forms a moment M of the force with respect to the rotation axis. This moment M causes the handwheel 10 to have a tendency to rotate counterclockwise. At the same time, since the flipping body 63 abuts against the housing 1, this rotation tendency can be balanced, so that the handwheel 10 is in a taut state in the low-magnification state. Thereby, the stability of the handwheel 10 in the low-magnification state can be enhanced, and at the same time, it can also prevent the handwheel 10 from being prone to small fluctuations in the low-magnification state.

[0032] As described above, it is only the preferred embodiment of the present invention, but the present invention is not limited to the above embodiments. As long as it achieves the technical effects of the present invention by any identical or similar means, it should fall within the protection scope of the present invention.
