Description

TECHNICAL FIELD

[0001] The present disclosure belongs to the technical field of variable-magnification sights and, more particularly, to a combination sight supported by a combined support.BACKGROUND

[0002] At present, sights are generally divided into fixed-magnification sights and variable-magnification sights. For fixed-magnification sights, a structure of an optical path is very simple, consisting of: an objective lens barrel group, a relay lens group, a reticle plate, and an eyepiece barrel group. Except for a ballistic adjustment mechanism and a diopter adjustment part, there is no other movable mechanism in the entire sight body. Having fewer movable parts means an increase in component reliability. When leaving the factory, unmovable parts of some fixed-magnification gun sights are permanently glued in place. In this way, during shooting, no matter how great the vibration is, only limited parts mentioned above may be subject to the vibration.

[0003] For variable-magnification sights, a structure of an optical path is complicated, consisting of: an objective lens barrel group, a relay lens group, a variable-magnification lens group, a magnification ring, a reticle plate, and an eyepiece barrel group. In addition to a ballistic adjustment mechanism and a diopter adjustment part, the variable-magnification lens group and the magnification ring are also typically movable mechanisms of the entire sight body. However, having more movable parts in the variable-magnification sights means a decrease in component reliability. Further, a traditional method of adjusting the sight to adapt to factors such as wind is generally achieved by movement of the gun, which results in poor adjustment accuracy.

[0004] The existing variable-magnification sights mainly include quick-aiming sights (such as Vortex Razor GEN2) and rapid variable-magnification sights (such as ELCAN SPECTERDR). These sights generally adjust magnification through a handwheel or a toggle. A main drawback of these sights is that when adjusting a magnifier, an obstruction area may be easily formed, which blocks a field of view of a shooter and creates a blind spot that is detrimental to shooting observation.

[0005] A sight system combining an internal red dot and a magnifier is composed of a red dot sight and a magnifier. The magnifier is a fixed-magnification telescope. In the combined system, the magnifier is usually mounted on a rotatable support, enabling the system to switch between configurations with and without the magnifier, thereby accommodating applications requiring aiming at both long and short distances.

[0006] For example, a patent application with application No. 2022229425207 provides a combined sight of a variable-reticle red dot sight and a magnifier. The combined sight includes a support, a positioning groove is disposed above a front portion of the support, and a red dot sight is disposed in the positioning groove; a magnifier flipping mechanism is disposed above a rear portion of the support, and a magnifier is movably connected to the magnifier flipping mechanism. The magnifier flipping mechanism includes a connecting plate, a rotating sleeve integrally formed with the connecting plate, and an elastic sheet disposed below the connecting plate; one end of the elastic sheet is fixed in a mounting groove on top of the support through an elastic sheet pressure plate, and another end of the elastic sheet is a free end; the rotating sleeve is movably connected to the support through a rotating shaft. For this sight, when the magnifier is not in use, the magnifier forms an obstruction area in front of the field of view, which shields the field of view of the shooter and creates a blind spot, making it unfavorable for shooting observation.SUMMARY

[0007] It is intended to solve a problem that a magnifier in an existing combination sight may shield part of an observation area and affect a field of view when the combination sight switches to a mode where the magnifier.

[0008] A combination sight supported by a combined support according to the present disclosure includes a support; a front-sighting-device mounting base is provided at a front part of the support, and a front sighting device, which is a red dot sight, is fixedly connected to the front-sighting-device mounting base; a magnifier connecting base is provided at a rear part of the support; a magnifier is provided on the magnifier connecting base through a movable connecting mechanism; and a magnifier support lifting mechanism is provided on the support.

[0009] Further, the movable connecting mechanism includes a front support rod and a rear support rod; the front support rod has connection holes at both ends, the connection hole at one end of the front support rod is movably connected with the magnifier, and the connection hole at another end of the front support rod is movably connected with the magnifier connecting base; the front support rod further has a hinge connecting hole; a groove for connection is provided at a periphery of the connection hole at the another end of the front support rod; the rear support rod has connection holes at both ends, the connection hole at one end of the rear support rod is movably connected with the magnifier, and the connection hole at another end of the rear support rod is movably connected with the magnifier connecting base.

[0010] Further, the magnifier support lifting mechanism includes a compression spring, a push rod, a hinge, two safety switches, and a rotating shaft; a compression spring mounting hole (32) is provided in a middle of the front-sighting-device mounting base; the compression spring is arranged within the compression spring mounting hole; one end of the compression spring is in contact with a first mounting screw, and another end of the compression spring is in contact with one end of the push rod inserted into the compression spring mounting hole; another end of the push rod is movably connected to the hinge through a second roller pin, and the hinge is movably connected to the front support rod through a first roller pin; the two safety switches are symmetrically arranged on left and right sides of the front-sighting-device mounting base; the front-sighting-device mounting base is provided with a rotating shaft mounting hole, the rotating shaft is arranged within the rotating shaft mounting hole, and each of two ends of the rotating shaft are connected with one safety switch.

[0011] Further, the safety switch includes an outer shell and an inner shell; a spring mounting groove is provided between the outer shell and the inner shell, and a spring is provided within the spring mounting groove; the inner shell is provided with a protrusion fitted with the groove, and the spring is above the protrusion.

[0012] The present disclosure has following advantageous effects. The combination sight supported by the combined support according to the present disclosure allows the magnifier to be movably connected to the rear part of the support through the movable connecting mechanism. As a result, when required, the magnifier is lifted by the magnifier support lifting mechanism to enter the in-use state; when not required, the magnifier is lowered by the magnifier support lifting mechanism to enter the not-in-use position and to be locked. During transition of the application states, the magnifier does not undergo any transverse positional change, so that the blind spot in the field of view of the shooter will not be increased. Moreover, the magnifier support lifting mechanism is simple, convenient, and quick to operate.

[0020] This embodiment provides a combination sight supported by a combined support as shown in FIGS. 1 to 8. The combination sight includes a support 15. A front-sighting-device mounting base 25 is provided at a front part of the support 15, and a front sighting device 26 is fixedly connected to the front-sighting-device mounting base 25. A magnifier connecting base 27 is provided at a rear part of the support 15, and a magnifier 1 is provided on the magnifier connecting base 27 through a movable connecting mechanism 28. A magnifier support lifting mechanism 29 is further provided on the support 15. Under the action of the movable connecting mechanism 28, the magnifier 1 may be rotated up and down to enter an in-use state or a not-in-use state. The magnifier support lifting mechanism 29 locks the magnifier 1 in the in-use state to ensure stability during use and improve aiming accuracy.

[0021] Further, the movable connecting mechanism 28 includes a front support rod 3 and a rear support rod 2. The front support rod 3 and the rear support rod 2 have the same H-shaped structure. The difference is that the front support rod 3 is provided with a groove 31 and a hinge connecting hole 30, while the rear support rod 2 is not provided with the groove 31 or the hinge connecting hole 30. Specifically, the front support rod 3 has connection holes at both ends thereof; the connection hole at one end of the front support rod 3 is movably connected with the magnifier 1 through a rotating screw 6, and the connection hole at the other end of the front support rod 3 is movably connected with the magnifier connecting base 27 through another rotating screw 6; moreover, the rotating screw 6 is further provided with a first washer 8. The front support rod 3 further has the hinge connecting hole 30, and the groove 31 for connection is provided at a periphery of the connection hole at the other end of the front support rod 3. The rear support rod 2 has connection holes at both ends thereof; the connection hole at one end of the rear support rod 2 is movably connected with the magnifier 1 through a rotating screw 6, and the connection hole at the other end of the rear support rod 2 is movably connected with the magnifier connecting base 27 through another rotating screw 6; moreover, the rotating screw 6 is provided with a first washer 8.

[0022] Further, as shown in FIGS. 2, 3, and 6, the magnifier support lifting mechanism 29 includes a compression spring 17, a push rod 24, a hinge 4, two safety switches 9, and a rotating shaft 21. A compression spring mounting hole 32 is provided in the middle of the front-sighting-device mounting base 25, and an extension direction of the compression spring mounting hole 32 is a front-rear direction. The compression spring 17 is arranged within the compression spring mounting hole 32. One end of the compression spring 17 is in contact with a first mounting screw 18, and the compression spring 17 is enclosed within the compression spring mounting hole 32 via the first mounting screw 18. The other end of the compression spring 17 is in contact with one end of the push rod 24 inserted into the compression spring mounting hole 32. A seal ring 23 is fitted over the one end of the push rod 24 in contact with the compression spring 17. The other end of the push rod 24 is movably connected to the hinge 4 through a second roller pin 7. The hinge 4 is also movably connected to the front support rod 3 through a first roller pin 5; specifically, the first roller pin 5 is inserted into a connection hole of the hinge 4 and the hinge connecting hole 30, thereby connecting the hinge and the front support in a movable manner. The two safety switches 9 are symmetrically arranged on left and right sides of the front-sighting-device mounting base 25. The front-sighting-device mounting base 25 is provided with a rotating shaft mounting hole 33. Specifically, the rotating shaft mounting hole 33 is provided in the rear of the front-sighting-device mounting base 25, the rotating shaft 21 is arranged within the rotating shaft mounting hole 33. Each of two ends of the rotating shaft 21 is connected with one safety switch 9, so that the magnifier 1 in a locked state may be unlocked during use by pressing either of the safety switches 9.

[0023] Further, the safety switch 9 includes an outer shell 34 and an inner shell 35, and the outer shell 34 and the inner shell 35 are connected by a mounting screw 10. A spring mounting groove 22 is provided between the outer shell 34 and the inner shell 35. A spring 12 is provided in the spring mounting groove 22, and a lower part of the spring 12 is limited by a screw 11. The inner shell 35 is provided with a protrusion 36 fitted with the groove 31. The spring 12 is above the protrusion 36. When the magnifier 1 is in use, the magnifier 1 is lifted to a position of the in-use state, and at this time the compression spring 17 is compressed, so that the compression spring 17 in a compressed state may continuously generate an elastic force that pushes the magnifier 1 back to a position of the not-in-use state. To maintain the magnifier 1 stably in the position of the in-use state, the fit between the groove 31 and the protrusion 36 firmly lock the front support rod 3. When the magnifier 1 is not needed, a locking state between the protrusion 36 and the groove 31 may be released simply by pressing the safety switch 9, so that the magnifier 1 returns to the not-in-use position under a pushing force of the compression spring 17, as shown in FIG. 6.

[0024] Further, a screw rod 20 is provided on the left side of the front-sighting-device mounting base 25, and a press block 14 is provided on the right side of the front-sighting-device mounting base 25. The screw rod 20 penetrates the front-sighting-device mounting base 25 in a left-right direction and is then connected to the press block 14, so as to connect and secure the combination sight supported by the combined support. The screw rod 20 is also provided with a limiting washer 19 to reduce wear between the screw rod 20 and the front-sighting-device mounting base 25 and to prevent the screw rod 20 from loosening under vibrating working conditions.

[0025] In actual use, when aiming at close-range targets, the magnifier is not required, in which case either of the safety switches 9 on the left and right sides may be simply pressed, and under the action of the compression spring 17 therein, the rear-mounted magnifier 1 may quickly enter a position shown in FIG. 6, neither affecting the use of the front sighting device 26 nor affecting the field of view in the left-right direction. When aiming at long-range targets, the magnifier 1 is required, in which case the rear-mounted magnifier 1 may be quickly lifted to a position shown in FIG. 7, and the safety switches 9 on the left and right sides may firmly lock the front support rod 3 and the rear support rod 2, allowing centers of the front sighting device 26 and the rear-mounted magnifier 1 to align on a same axis, so as to aim at the long-range targets accurately.

[0026] In conclusion, the combination sight supported by the combined support allows the magnifier to be movably connected to the rear part of the support through the movable connecting mechanism. As a result, when required, the magnifier is lifted by the magnifier support lifting mechanism to enter the in-use state; when not required, the magnifier is lowered by the magnifier support lifting mechanism to enter the not-in-use position and to be locked. During transition of the application states, the magnifier does not undergo any transverse positional change, so that the blind spot in the field of view of the shooter will not be increased. Moreover, the magnifier support lifting mechanism is simple, convenient, and quick to operate.
