Description

Technical Field

[0001] The invention relates to the technical field of optics, and in particular to a manual switching mechanism for double reticle plates of a sight. Background Art

[0002] The scope is installed on the weapon system, mainly to provide the user with the function of aiming and locating the target, so as to achieve efficient and accurate target hitting. Generally, there is a reticle inside the scope, which is mainly used to guide the user to aim and to measure the distance to the target, so as to estimate the target distance and aim and shoot according to the corresponding scale of the reticle.

[0003] The sight of traditional technology is usually fixedly connected to the weapon system. When using a weapon system equipped with a sight, most of them can only achieve aiming and ranging of one or two types of ammunition, and cannot achieve aiming and ranging of multiple types of ammunition. When the weapon system uses more than two types of ammunition, it is necessary to switch to a different sight, which causes inconvenience in use. Summary of the invention

[0004] In order to overcome the defects of the prior art, the technical problem to be solved by the present invention is to provide a manual switching mechanism for the double reticle of a sight, which can solve the problem of needing to replace different sights when using multiple types of ammunition, realize convenient and efficient switching of reticle plates, and expand the application range of the sight.

[0005] The technical solution of the present invention is: the manual switching mechanism of the double-reticle of the sight comprises: a housing (1), two reticle seat groups, and a hand wheel switching assembly;

[0006] The shell body is covered outside the reticle seat group, and each reticle seat group includes: a reticle seat, a reticle pressure ring, and a reticle;

[0007] The two reticle plates are respectively mounted on two reticle plate seats, and the two reticle plate seats are then respectively mounted on two mutually perpendicular vertical surfaces at the bottom of the switching turntable;

[0008] The hand wheel switching assembly comprises, from top to bottom, a switching hand wheel (2), a switching turntable (3), a fixing pin (4), a scale indicator ring (7), a scale indicator ring clip (8), a positioning steel ball (11), a rotation positioning spring (12), and a positioning pin (13);

[0009] The reticle plate pressure ring (16) and the reticle plate seat (15) are screwed to fix the reticle plate (17) on the reticle plate seat (15). The reticle plate seat assembly is connected to the hand wheel switching assembly by screws. When the switching hand wheel (2) rotates, the switching turntable (3) is driven to rotate with the axis as the rotation center through the fixing pin (4). The reticle plate seat (15), the reticle indicator ring clamp (8) and the reticle indicator ring (7) also rotate accordingly. There are two positioning grooves at 90 degrees on the inner ring of the reticle indicator ring, and the name of the current reticle plate is engraved at the corresponding position on the outer ring. When the reticle indicator ring rotates 90 degrees, the positioning pin (13) limits the rotation of the reticle indicator ring (7). At the same time, the positioning steel ball (11) is stuck in the positioning groove of the reticle indicator ring (7) under the pressure of the rotation positioning spring (12).

[0010] The reticle plate pressure ring and the reticle plate seat of the present invention are screwed to fix the reticle plate on the reticle plate seat to form a reticle plate seat group. Then, the reticle plate seat group is connected to the hand wheel switching assembly by screws. The hand wheel is manually rotated to switch, and the switching turntable is driven to rotate with the axis as the rotation center by the fixing pin. The reticle plate seat, the reticle indicator ring clip and the reticle indicator ring also rotate accordingly. When the reticle indicator ring rotates 90°, the positioning pin limits the rotation of the reticle indicator ring. At the same time, the positioning steel ball is stuck in the positioning groove of the reticle indicator ring under the pressure of the rotating positioning spring, so as to achieve the effect of switching and positioning of the double reticle plates, and effectively reduce the shaking of the reticle plates after switching, so as to achieve high-precision and efficient aiming. Therefore, it is possible to solve the problem of needing to replace different sights when using multiple types of ammunition, realize convenient and efficient switching of reticle plates, and expand the application range of the sight.

DETAILED DESCRIPTION

[0018] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0019] It should be noted that the term "comprises" and any variations in the specification and claims of the present invention and the above-mentioned drawings are intended to cover non-exclusive inclusions. For example, a process, method, apparatus, product or equipment that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or are inherent to these processes, methods, products or equipment.

[0020] like Figure 1-Figure 6 As shown, the manual switching mechanism of the dual-reticle sight comprises: a housing 1, two reticle seat groups, and a handwheel switching assembly;

[0021] The shell body is covered outside the reticle seat group, and each reticle seat group includes: a reticle seat, a reticle pressure ring, and a reticle;

[0022] The two reticle plates are respectively mounted on two reticle plate seats, and the two reticle plate seats are then respectively mounted on two mutually perpendicular vertical surfaces at the bottom of the switching turntable;

[0023] The hand wheel switching assembly includes, from top to bottom, a switching hand wheel 2, a switching turntable 3, a fixing pin 4, a scale indicator ring 7, a scale indicator ring clip 8, a positioning steel ball 11, a rotation positioning spring 12, and a positioning pin 13;

[0024] The reticle plate pressure ring 16 and the reticle plate seat 15 are screwed to fix the reticle plate 17 on the reticle plate seat 15. The reticle plate seat assembly is connected to the hand wheel switching assembly by screws. The switching hand wheel 2 rotates, and the switching turntable 3 is driven to rotate with the axis as the rotation center through the fixing pin 4. The reticle plate seat 15, the reticle indicator ring clip 8 and the reticle indicator ring 7 also rotate accordingly. There are two 90° positioning grooves on the inner ring of the reticle indicator ring, and the name of the current reticle is engraved at the corresponding position on the outer ring

[0025] (The name of the scale plate currently in use can be known at a specific position). When the scale indicator ring rotates 90°, the positioning pin 13 limits the rotation of the scale indicator ring 7. At the same time, the positioning steel ball 11 is stuck in the positioning groove of the scale indicator ring 7 under the pressure of the rotating positioning spring 12.

[0026] like Figure 3 As shown, when the switching hand wheel is turned, the scale indicator ring and the scale plate switching turntable (including two scale plates) can be driven to rotate simultaneously. At the same time, the positioning steel ball is pressed into the positioning groove on the inner ring of the scale indicator ring under the pressure of the rotating positioning spring to achieve the switching positioning of the two scale plates. Since the inner ring of the scale indicator ring is provided with two positioning grooves at 90°, when the following switching hand wheel is rotated into place, the positioning steel ball is stuck in the positioning groove of the scale indicator ring under the pressure of the rotating positioning spring, eliminating the influence of the radial clearance and achieving high-precision positioning.

[0027] The reticle plate pressure ring and the reticle plate seat of the present invention are screwed to fix the reticle plate on the reticle plate seat to form a reticle plate seat group. Then, the reticle plate seat group is connected to the hand wheel switching assembly by screws. The hand wheel is manually rotated to switch, and the switching turntable is driven to rotate with the axis as the rotation center by the fixing pin. The reticle plate seat, the reticle indicator ring clip and the reticle indicator ring also rotate accordingly. When the reticle indicator ring rotates 90°, the positioning pin limits the rotation of the reticle indicator ring. At the same time, the positioning steel ball is stuck in the positioning groove of the reticle indicator ring under the pressure of the rotating positioning spring, so as to achieve the effect of switching and positioning of the double reticle plates, and effectively reduce the shaking of the reticle plates after switching, so as to achieve high-precision and efficient aiming. Therefore, it is possible to solve the problem of needing to replace different sights when using multiple types of ammunition, realize convenient and efficient switching of reticle plates, and expand the application range of the sight.

[0028] Preferably, if Figure 2 As shown, there is a handwheel compression spring 6 below the switching handwheel. The handwheel compression spring is used to eliminate the axial movement of the switching turntable.

[0029] Preferably, if Figure 5 As shown, the bottom of the switching turntable is sleeved with a switching table seat 9, and a positioning pin is inserted into the switching table seat. The positioning pin is used to limit the rotation angle of the switching turntable.

[0030] Preferably, if Figure 2As shown, the upper end of the hand wheel compression spring is provided with a first spring gasket 5, and the lower end is provided with a second spring gasket 10. The first spring gasket and the second spring gasket are used to prevent the friction force of the spring from being too large and scratching the switching hand wheel and the switching pedestal.

[0031] Preferably, if Figure 2 As shown, a pressing sheet 18 is provided on the outer side of the reticle seat to evenly distribute the pressure of the screw on the surface of the reticle seat and protect the screw and the reticle seat.

[0032] Preferably, if Figure 2 As shown, the inner side of the reticle seat is provided with a reticle adjustment gasket 14. The relative position of the reticle seat assembly on the vertical plane of the switching turntable is finely adjusted.

[0033] Preferably, if Figure 4 As shown, the graticule seat 15 is provided with an arc-shaped through hole to adjust the relative position of the graticule 17 on the vertical plane of the switching turntable 3.

[0034] Preferably, if Figure 5 As shown, the switching hand wheel 2, the scale indicator ring 7, and the scale indicator ring clip 8 are fixedly connected by multiple screws so that the three cannot slide relative to each other.

[0035] Preferably, the switching hand wheel and the switching turntable are connected by a thread and a fixing pin. The main purpose of the thread is to adjust the relative position of the switching hand wheel and the switching turntable, and the fixing pin fixes the switching hand wheel and the switching turntable and transmits torque at the same time.

[0036] Preferably, the switching hand wheel and the differentiation indicator ring are connected by two set screws so that there is no relative sliding between the two.

[0037] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the protection scope of the technical solution of the present invention.
