Sighting scope with external binding adjustment device

Abstract

This invention discloses a scope with an externally mounted reticle adjustment device, including a scope body, a reticle assembly disposed within the scope body, and elevation and directional adjustment groups on the scope body. The elevation adjustment group is used to adjust the elevation movement of the reticle assembly, realizing the elevation movement of the aiming point. The directional adjustment group is used to adjust the horizontal movement of the reticle assembly, realizing the horizontal movement of the aiming point. The scope with an externally mounted reticle adjustment device adds an externally mounted synchronization structure to the reticle adjustment mechanism. During the adjustment process, the adjustment direction and number of turns of the handwheel can be displayed. After aiming at 100 meters, the aiming point is preset by adjusting the elevation and directional handwheels according to the target distance, wind speed, ambient temperature, air pressure, and other conditions, and according to the requirements of the firing table, thereby improving the ability to quickly and accurately engage targets.

Description

Technical Field

[0001] This invention relates to the field of firearm sight technology, and in particular to a sight with an external reticle adjustment device. Background Technology

[0002] In the use of firearms, in order to improve shooting accuracy and efficiency, firearms use scopes for long-distance observation and aiming. During the shooting process, the user adjusts the height and direction of the reticle of the scope according to the environmental conditions (wind speed, ambient temperature and air pressure, etc.) and the target distance. The adjustment of the reticle is accomplished by an external adjustment device. The adjustment device converts rotational motion into linear motion through a screw mechanism, which is used to adjust the position of the reticle of the scope. A tiny movement of the reticle is equivalent to a displacement of hundreds or thousands of times for a target at a distance of 100 meters or more. Therefore, the accuracy of the adjustment device affects the accuracy of the scope and determines the shooting accuracy.

[0003] Due to the unique structure of this adjustment device, the adjustment screw cannot move up and down, and the external stapling function cannot be directly implemented. When used as a regular scope, the shooting distance varies little, and the reticle adjustment range is small, making it barely usable. However, when used as a professional scope, the shooting distance varies greatly (typically 100 meters for aiming, shooting targets over 1000 meters, with aiming point corrections of 10 mils or more). With a very large reticle adjustment range, the handwheel needs to be turned many times. Without the external stapling function, it's impossible to determine the reticle adjustment position, hindering rapid and accurate aiming at different distances, and preventing accurate return to the 100-meter aiming elevation / azimuth handwheel position, thus affecting subsequent shooting accuracy. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a sight with an external reticle adjustment device that can realize the position coordinates during the reticle adjustment process, enabling rapid aiming and accurate shooting at different distances.

[0005] The objective of this invention is achieved as follows:

[0006] A scope with an externally mounted reticle adjustment device includes a scope body (1), a reticle assembly (2) inside the scope body (1), and an elevation adjustment assembly (3) and a directional adjustment assembly (4) on the scope body (1).

[0007] The reticle assembly (2) includes a support assembly (21) with reticles, a high-low slider (22), and a direction slider (23). The support assembly (21) has a groove for the high-low slider (22) in the horizontal direction. The high-low slider (22) slides in the corresponding groove and forms a vertical positioning. The support assembly (21) has a groove for the direction slider (23) in the vertical direction. The direction slider (23) slides in the corresponding groove and forms a horizontal positioning. Both the high-low slider (22) and the direction slider (23) have threaded holes.

[0008] The height adjustment group (3) / direction adjustment group (4) includes an adjustment screw group (5). The inner end of the adjustment screw group (5) is a screw. The outer end of the adjustment screw group (5) is provided with a strip hole along the axial direction. An adjustment plate is provided in the middle of the adjustment screw group (5). The screw end of the adjustment screw group (5) is engaged with the threaded hole on the height slider (22) / direction slider (23) to form a screw nut mechanism. An elastic positioning device is provided in the adjustment plate.

[0009] The height adjustment group (3) / direction adjustment group (4) is equipped with a segmented positioning group (6) and an external binding synchronization group (7). The segmented positioning group includes a handwheel seat (61) and a positioning gear ring (62). The handwheel seat (61) is cylindrical. One end of the handwheel seat (61) is fixedly connected to the mirror body (1). The adjustment screw group (5) is installed in the handwheel seat (61). The handwheel seat (61) has an internal thread, and the positioning gear ring (62) has an external thread. The external thread of the positioning gear ring (62) and the internal thread of the handwheel seat (61) are connected. With fixed fit, the outer circumferential surface of the adjusting plate of the adjusting screw assembly (5) is provided with a step, which is located between the handwheel seat (61) and the positioning gear ring (62). The positioning gear ring (62) controls the axial clearance on both sides of the step of the adjusting plate, ensuring that the adjusting screw assembly (5) can rotate without clearance (sliding fit is formed on both sides of the step). The inner circumference of the positioning gear ring (62) is evenly distributed with straight teeth. The elastic positioning device in the adjusting plate cooperates with the straight teeth of the positioning gear ring (62) to realize the rotational elastic positioning of the adjusting screw assembly (5).

[0010] The outer binding synchronization assembly (7) includes a fixed seat (71), a guide screw (72), and a handwheel cover (73). The fixed seat (71) is located between the handwheel seat (61) and the outer ends of the high and low screw assembly (5). The outer peripheral surface of the fixed seat (71) is stepped. The large end of the outer peripheral surface of the fixed seat (71) is threaded into the handwheel seat (61). There is a gap between the fixed seat (71) and the positioning gear ring (62). The small end of the outer peripheral surface of the fixed seat (71) is provided with a radial through hole. The guide screw... The screw (72) passes through the strip hole at the outer end of the adjusting screw assembly (5) and is threadedly engaged with the fixed seat (71) for fixation. The strip hole at the outer end of the adjusting screw assembly (5) is used to allow the guide screw (72) to move. The handwheel cover (73) is fitted on the small end of the outer peripheral surface of the handwheel seat (61) and the fixed seat (71). The handwheel cover (73) is fixedly connected to the fixed seat (71). The handwheel seat (61) and the handwheel cover (73) are respectively provided with scale lines to indicate the adjustment amount of the adjusting screw assembly (5).

[0011] Preferably, the adjusting plate of the adjusting screw assembly (5) is provided with a mounting hole along the radial direction. A steel ball (52), a positioning pin (53), an adjusting spring (54), and a screw (55) are arranged in sequence in the mounting hole. The screw (55) is threaded and forms an axial positioning in the mounting hole. The steel ball (52) is engaged with the spur teeth of the positioning gear ring (62).

[0012] Preferably, the inner end of the adjusting screw assembly (5) is fitted with a support ring (8) and a support spring (9) to eliminate gaps and provide a buffering effect.

[0013] Preferably, one end of the handwheel seat (61) is provided with an end wall, which is fixedly connected to the mirror body (1) by a screw (10). The segmented positioning group also includes an O-ring seal (64), which is located between the end wall of the adjustment plate and the handwheel seat (61) to form a seal.

[0014] Preferably, the outer binding synchronization group further includes a set screw (74), the handwheel cover (73) and the fixed seat (71) are fixedly connected by the set screw (74), and the handwheel cover (73) and the handwheel seat (61) are sealed by an O-ring seal (75).

[0015] Preferably, a waterproof sealing ring (11) is provided between the mirror body and the handwheel seat.

[0016] Preferably, the grading positioning group further includes a screw three (63), which passes through the handwheel seat (61) and contacts the positioning gear ring (62) to lock the positioning gear ring (62).

[0017] Preferably, the upper edge of the high and low handwheel seat (61) is engraved with equidistant horizontal lines, and the handwheel cover (73) is engraved with the same number of vertical lines as the positioning tooth ring (63). The division position is determined by the number of visible horizontal lines on the handwheel seat (61) and the position of the vertical lines on the handwheel cover (73) to accurately correct the aiming point.

[0018] Due to the adoption of the above technical solution, the present invention has the following beneficial effects:

[0019] This invention features a simple structure. The original grading and positioning group remains unchanged, but an external binding grading adjustment device is added, moving synchronously with the positioning mechanism. Synchronization is achieved through a mechanical structure. The adjustment process displays the handwheel's adjustment direction and number of rotations, facilitating rapid switching between different distances without requiring recalibration. The added handwheel and external binding synchronization group requires minimal modification and is stable and reliable.

[0020] After calibrating the gun at 100 meters, the aiming point is preset by adjusting the elevation and directional handwheels according to the target distance, wind speed, ambient temperature and air pressure, and the requirements of the firing table, thereby improving the ability to strike quickly and accurately.

[0033] The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0034] See Figures 1-6 A scope with an externally mounted reticle adjustment device includes a scope body 1, a reticle assembly 2 disposed within the scope body, and an elevation adjustment assembly 3 and a directional adjustment assembly 4 also disposed on the scope body. The elevation adjustment assembly 3 and the directional adjustment assembly 4 adopt completely identical or similar structures. The elevation adjustment assembly 3 and the directional adjustment assembly 4 are fixedly connected to the scope body as required. The reticle assembly 2, elevation adjustment assembly 3, and directional adjustment assembly 4 are connected as a whole as required. The elevation adjustment assembly 3 has an adjusting screw assembly 5 and an elevation slider 22 that are threadedly connected to adjust the elevation movement of the reticle assembly, thereby moving the aiming point in the elevation direction. The directional adjustment assembly 4 has an adjusting screw assembly 5 and a directional slider 23 that are connected to adjust the horizontal movement of the reticle assembly, thereby moving the aiming point in the horizontal direction. The adjusting screw assembly 5 can only rotate. The scope has a gradation positioning group in the elevation adjustment assembly 3 and the directional adjustment assembly 4. The gradation positioning group is used to ensure the accuracy of the adjustment quantity and the precision of the gradation adjustment when adjusting the reticle. The scope handwheel external binding synchronization group is used to display the adjustment direction and quantity of the handwheel (record the number of turns) when adjusting the reticle, thereby achieving fast and accurate adjustment. The handwheel seat 61 and the handwheel cover 73 both have corresponding engravings to cooperate with the gradation positioning group and the handwheel external binding synchronization group. The support ring 8 and the support spring 9 eliminate gaps and play a buffering role.

[0035] The height adjustment mechanism includes a reticle assembly 2, an adjusting screw assembly 5, a grading positioning assembly 6, an external binding synchronization assembly 7, a support ring 8, and a support spring 9. The grading positioning assembly 6 is fixedly connected to the mirror body 1. The adjusting screw assembly 5 passes through the grading positioning assembly 6 and the mirror body 1 and is connected to the height slider 22 or the direction slider 23 of the reticle assembly 2. The external binding synchronization assembly 7 is connected to the grading positioning assembly 6, thus completing the height adjustment assembly 3 and the direction adjustment assembly 4 being fixedly connected to the mirror body as required.

[0036] The reticle assembly 2 includes a reticle support assembly 21, a height slider 22, and a direction slider 23. The height slider 22 and the direction slider 23 move within the groove of the reticle support assembly 21. When the height adjustment mechanism is used, the direction slider restricts the left and right position of the reticle assembly 2, allowing it to move only in the height direction. When the direction adjustment mechanism is used, the height slider restricts the height position of the reticle assembly 2, allowing it to move only in the left and right direction.

[0037] The thread gap between the high and low screw 5 and the high and low slider 6 is eliminated by the support ring 8 and the support spring 9.

[0038] The adjusting screw assembly 5 includes an adjusting screw 51, a steel ball 52, a positioning pin 53, an adjusting spring 54, and a screw 55. The spring 54 ensures that the steel ball 52 can reciprocate when pressed, and the steel ball 52 enhances its wear resistance.

[0039] The geared positioning assembly includes a handwheel seat 61, a positioning gear ring 62, a third screw 63, and a second O-ring seal 64. The positioning gear ring 62 presses the screw assembly 5 and the second O-ring seal 64 into the handwheel seat 61 as required. The positioning gear ring 62 has evenly distributed straight teeth on its inner circumference, and the elastic positioning device within the adjusting screw assembly 5 ensures accurate positioning during rotation; the positioning gear ring 62 also controls the up-and-down movement of the adjusting screw assembly 5; the third screw 63 prevents the positioning gear ring 62 from loosening.

[0040] The external binding synchronization assembly includes a fixed base 71, a guide screw 72, a handwheel cover 73, and a set screw 74. The fixed base 71 is fitted onto the high / low screw assembly 5 and screwed into the handwheel seat 61 as required. The guide screw 72 is passed through the fixed base 71 and the high / low screw assembly 5 and tightened onto the fixed base 71. The handwheel cover 73 is aligned with the scribe line of the fixed base 71 as required and connected as a single unit with the set screw 74. Rotating the handwheel cover 73 causes the high / low screw assembly 5 to rotate via the fixed base 71 and the guide screw 72. The high / low screw assembly 5 drives the high / low slider 22 to move up and down, and the high / low slider 22 drives the reticle assembly 2 to move up and down. Rotating the handwheel cover 73 simultaneously causes the thread between the handwheel seat 61 and the fixed base 71 to move the fixed base 71 up and down, which in turn drives the handwheel cover 73 to move up and down.

[0041] The external binding markings include a handwheel seat 61 and a handwheel cover 73. The high and low handwheel seat 61 is engraved with equidistant horizontal lines along its upper and lower edges. The handwheel cover 73 is engraved with the same number of vertical engravings as the positioning tooth ring 63. The number of visible lines on the handwheel seat 61 and the position of the engravings on the handwheel cover 73 are used to determine the gradation position and accurately correct the aiming point.

[0042] Specifically:

[0043] like Figure 1 , 2A scope with an external binding reticle adjustment device includes a scope body 1, a reticle assembly 2 disposed within the scope body 1, and an elevation adjustment assembly 3 and a directional adjustment assembly 4 also disposed on the scope body. An adjustment screw assembly 5, a reticle positioning assembly 6, and an external binding synchronization assembly 7 are disposed within the elevation / directional adjustment assembly 3 / directional adjustment assembly 4, and a support ring 8 and a support spring 9 are provided to eliminate gaps between parts and reduce buffering. The handwheel seat 61 of the elevation / directional adjustment assembly 3 / directional adjustment assembly 4 is adjusted as required and then fixed to the scope body with screws 10. A waterproof sealing ring 11 is provided between the scope body and the handwheel seat, and the end of the handwheel seat has a mounting groove for the sealing ring 11 and a mounting hole for the screws 10.

[0044] like Figure 3 A sight with an external reticle adjustment device includes a reticle support assembly 21, an elevation slider 22 and a directional slider 23 mounted on the reticle support assembly 21. When the elevation adjustment assembly 3 is adjusted, the elevation slider 22 moves up and down, causing the reticle support assembly 21 to move synchronously. Limited by the directional slider 23, the directional position remains unchanged during adjustment. Similarly, when the directional adjustment assembly 4 is adjusted, the directional slider 23 moves left and right, causing the reticle support assembly 21 to move synchronously. Limited by the elevation slider 22, the elevation position remains unchanged during adjustment.

[0045] like Figure 4 A scope with an external reticle adjustment device includes an adjustment screw assembly 5 comprising an adjustment screw 51, an adjustment plate arranged vertically inside the adjustment screw 51, and a steel ball 52, a positioning pin 53, an adjustment spring 54, and a screw 55 arranged sequentially inside the adjustment plate. Pressing the steel ball 52 causes the positioning pin 53 to reciprocate.

[0046] like Figure 5 A sight with an external reticle adjustment device includes a reticle positioning assembly comprising a handwheel seat 61, an adjusting screw assembly 5 and a positioning gear ring 62 located within the handwheel seat 61 for rotational positioning. A screw 63 prevents the positioning gear ring 62 from loosening during use, and an O-ring 64 located between the adjusting screw assembly 5 and the handwheel seat 61 provides a sealing function.

[0047] like Figure 6 A scope with an external reticle adjustment device includes an external reticle synchronization assembly comprising a handwheel base 61, a fixed base 71 disposed within the handwheel base 61, a guide screw 72 passing through the fixed base 71 and an adjusting screw assembly 5, and a handwheel cover 73 fixed to the fixed base 71 by a set screw 74 as required. An O-ring 75 achieves a sealing effect between the handwheel base 61 and the handwheel cover 73.

[0048] This invention optimizes the original reticle adjustment mechanism by adding an external binding reticle adjustment device, enabling synchronous movement with the original reticle adjustment mechanism. The structure is stable and reliable, and the adjustment process can display the adjustment direction and number of rotations of the handwheel, facilitating rapid switching between different distances.

[0049] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.
