Description

Technical Field

[0001] The invention relates to the technical field of firearm aiming, and in particular to an adjusting hand wheel group and a sighting scope with a zero position limiting function. Background Art

[0002] In order to help users achieve accurate shooting, optical sights are often added to firearms as auxiliary aiming tools. However, even in ideal conditions, due to the weight of the bullet, the user can only hit point B below point A when aiming at the center of the target. Therefore, the firearm must be calibrated before use.

[0003] The calibration process is as follows: keep the gun position unchanged, turn the adjusting handwheel to make the actual impact point B in the scope lens coincide with the cross center point of the reticle; unscrew the zeroing screw and remove the adjusting handwheel, turn the adjusting handwheel until the zero position of the scale mark on the outer wall is aligned with the zero position mark on the lens barrel, then reinstall the adjusting handwheel to return the adjusting handwheel group to zero.

[0004] After the firearm is calibrated, the shooting accuracy will be greatly improved when shooting again under the same conditions. However, the zero position of the adjustment handwheel group on the existing scope is not unique. After the adjustment handwheel is turned, the user may forget the zero position, and it is difficult for other users to know the specific zero position. The subsequent zeroing process is prone to multiple turns or wrong turns. For example, when turning back to the zero position from half a turn, it may turn one more turn in the forward or reverse direction. Therefore, the existing technology has disadvantages. Summary of the invention

[0005] The purpose of the present invention is to provide an adjusting hand wheel group and a sighting scope with a zero position limit function in view of the existing technical status, wherein the adjusting hand wheel group can quickly return to zero on the sighting scope to avoid erroneous operation during the zeroing process.

[0006] In order to achieve the above object, the present invention adopts the following technical scheme:

[0007] An adjusting handwheel assembly with a zero position limit function comprises an adjusting handwheel, a zeroing screw, a handwheel seat, a handwheel buckle cover, an adjusting seat, and an adjusting screw. The adjusting seat is nested in the handwheel seat, and matching toothed surfaces are respectively provided on the adjusting seat and the handwheel seat. The upper end of the adjusting screw is connected to the adjusting seat in an embedded rotational fit, and the middle of the adjusting screw is connected to the handwheel seat in a threaded connection. The handwheel buckle cover is provided on the handwheel seat and the two are fixedly connected. A scale ruler is provided on the outer wall of the adjusting handwheel, and the adjusting handwheel is locked and connected to the adjusting seat through the zeroing screw.

[0008] The adjusting hand wheel is provided with a linkage ring and the linkage ring is fixedly connected to the adjusting hand wheel. The outer wall of the linkage ring is provided with a linkage protrusion formed integrally with the linkage ring along any radial direction thereof. The linkage protrusion on the linkage ring is aligned with the zero position of the scale mark on the outer wall of the adjusting hand wheel.

[0009] It also includes a stop ring, wherein an annular surface integrally formed therewith is provided in an upper port of the stop ring, a linkage groove is provided on the annular surface along any radial direction thereof, a first limiting protrusion is provided on the bottom surface of the annular surface at an edge of one side of the linkage groove, the stop ring is nested on the hand wheel buckle cover and the two are threadedly connected, and after the adjusting hand wheel and the adjusting seat are locked, the linkage protrusion is embedded in the linkage groove;

[0010] A second limiting protrusion is provided on the top surface of the handwheel buckle cover. When the stop ring is tightened on the handwheel buckle cover until the first limiting protrusion and the second limiting protrusion form a limit, the linkage groove is located directly above the second limiting protrusion.

[0011] Furthermore, the second limiting protrusion is a limiting screw, and the top surface of the handwheel buckle cover is provided with an assembly screw hole matching the limiting screw.

[0012] Furthermore, the height of the linkage protrusion is greater than the height of the toothed surface on the adjustment seat.

[0013] Furthermore, the first limiting protrusion is located at the left edge of the linkage groove, and the scale marking ruler on the outer side wall of the adjusting hand wheel is counterclockwise.

[0014] Furthermore, the first limiting protrusion is located at the right edge of the linkage groove, and the scale marking ruler on the outer wall of the adjusting hand wheel is clockwise.

[0015] A sighting scope comprises a lens barrel and an adjusting hand wheel group installed on the lens barrel, a zero position mark is provided on the lens barrel, a hand wheel seat in the adjusting hand wheel group is arranged on the lens barrel and the two are fixedly connected, the lower end of the adjusting screw in the adjusting hand wheel group is connected to the adjusting structure in the lens barrel, and a second limiting protrusion on the hand wheel buckle cover in the adjusting hand wheel group is aligned with the zero position mark on the lens barrel.

[0016] Furthermore, a plurality of assembly screw holes matching the limit screws are evenly arranged on the top surface of the hand wheel buckle cover along the circumferential direction.

[0017] The beneficial effects of the present invention are:

[0018] The sight has added a linkage ring, a stop ring and a second limit protrusion in the adjustment handwheel group. The linkage ring is arranged inside the adjustment handwheel, and the second limit protrusion is arranged on the handwheel buckle cover. After calibration, when the adjustment handwheel is rotated toward the zero position, the stop ring is driven to rotate through the linkage ring, so that the first limit protrusion on the stop ring and the second limit protrusion on the handwheel buckle cover form a limit at the zero position mark, so that the adjustment handwheel group can be quickly returned to zero to avoid erroneous operation during the zeroing process.

[0027] The present invention will be further described below in conjunction with the accompanying drawings.

[0028] See also Figure 1 As shown, an adjusting handwheel assembly with a zero position limit function comprises an adjusting handwheel 1, a zeroing screw 2, a handwheel seat 5, a handwheel buckle cover 6, an adjusting seat 3, and an adjusting screw 4.

[0029] The adjustment seat 3 is nested in the handwheel seat 5, and matching toothed surfaces are respectively provided on the adjustment seat 3 and the handwheel seat 5. When the toothed surfaces on the adjustment seat 3 are meshed with the toothed surfaces on the handwheel seat 5, the adjustment seat 3 cannot rotate. When the toothed surfaces on the adjustment seat 3 are disengaged from the toothed surfaces on the handwheel seat 5, the adjustment seat 3 can rotate.

[0030] The upper end of the adjusting screw 4 is connected to the adjusting seat 3 in an embedded rotational fit. The conventional method is that a square column is embedded in a square hole to form a rotational fit. The middle part of the adjusting screw 4 is threadedly connected to the handwheel seat 5. The adjusting seat 3 can drive the adjusting screw 4 to rotate in the handwheel seat 5 and move up and down.

[0031] The hand wheel buckle cover 6 is arranged on the hand wheel seat 5 and the two are fixedly connected, generally by threaded connection and then locked with glue.

[0032] The outer wall of the adjusting hand wheel 1 is provided with a scale ruler, which is used to indicate the adjustment amount of the adjusting structure. The adjusting hand wheel 1 is locked and connected with the adjusting seat 3 through the zeroing screw 2. The upper end face of the zeroing screw 2 is provided with a straight opening, which can be tightened or loosened with a coin or the like. A rubber ring is provided on the outer wall of the hand wheel seat 5. After the adjusting hand wheel 1 is locked with the adjusting seat 3, the inner wall of the adjusting hand wheel 1 contacts the rubber ring, which can increase the hand feel of turning the adjusting hand wheel 1.

[0033] See also Figure 3 , 4 As shown, in the above technical solution, the adjusting hand wheel 1 is provided with a linkage ring 7 and the linkage ring 7 is fixedly connected to the adjusting hand wheel 1, and the outer wall of the linkage ring 7 is provided with a linkage protrusion 11 integrally formed therewith along any radial direction thereof. The linkage protrusion 11 on the linkage ring 7 is aligned with the zero position of the scale mark on the outer wall of the adjusting hand wheel 1.

[0034] See also Figure 5 , 6 As shown, the above technical scheme also includes a stop ring 8, and the upper end of the stop ring 8 is provided with a circular surface 14 integrally formed therewith, and the circular surface 14 is provided with a linkage groove 12 along any radial direction thereof, and the bottom surface of the circular surface 14 is located at one side edge of the linkage groove 12 and is provided with a first limiting protrusion 13, the stop ring 8 is nested on the handwheel buckle cover 6 and the two are threadedly connected, and after the adjusting handwheel 1 and the adjusting seat 3 are locked, the linkage protrusion 11 is embedded in the linkage groove 12.

[0035] See also Figure 2 As shown, in the above technical solution, the top surface of the hand wheel buckle cover 6 is provided with a second limiting protrusion, and when the stop ring 8 is tightened on the hand wheel buckle cover 6 until the first limiting protrusion 13 and the second limiting protrusion form a limit, the linkage groove 12 is located directly above the second limiting protrusion. After the adjustment hand wheel 1 is installed so that the linkage protrusion 11 is embedded in the linkage groove 12, the zero position of the scale indicator on the outer wall of the adjustment hand wheel 1 is aligned with the second limiting protrusion on the hand wheel buckle cover 6.

[0036] The second limiting protrusion is a limiting screw 10 , and the top surface of the handwheel buckle cover 6 is provided with a plurality of assembly screw holes 9 matching the limiting screw 10 .

[0037] When rotating the adjusting hand wheel 1, it is necessary to pull it upwards so that the toothed surfaces on the adjusting seat 3 and the toothed surfaces on the handwheel seat 5 are disengaged. Therefore, the height of the linkage protrusion 11 should be greater than the height of the toothed surface on the adjusting seat 3 to avoid the linkage protrusion 11 and the linkage groove 12 being unable to form a linkage fit after the adjusting hand wheel 1 is lifted upwards.

[0038] In one embodiment, the first limiting protrusion 13 is located at the left edge of the linkage groove 12, and the scale marking on the outer wall of the adjustment hand wheel 1 is counterclockwise. In another embodiment, the first limiting protrusion 13 is located at the right edge of the linkage groove 12, and the scale marking on the outer wall of the adjustment hand wheel 1 is clockwise.

[0039] See also Figure 7 As shown, a sighting scope includes a lens barrel 15 and an adjusting hand wheel group installed on the lens barrel 15. A zero position mark is provided on the lens barrel 15, and the zero position mark includes but is not limited to a dot and a straight line.

[0040] After the adjusting handwheel assembly is installed on the lens barrel 15, the handwheel seat 5 in the adjusting handwheel assembly is arranged on the lens barrel 15 and the two are fixedly connected, generally by threaded connection and then locked with glue; the lower end of the adjusting screw 4 in the adjusting handwheel assembly is connected to the adjusting structure in the lens barrel 15, and when the adjusting seat 3 drives the adjusting screw 4 to rotate in the handwheel seat 5 and move up and down, the adjusting screw 4 drives the adjusting structure in the lens barrel 15 to adjust the optical axis state; the second limiting protrusion on the handwheel buckle cover 6 in the adjusting handwheel assembly is aligned with the zero position mark on the lens barrel 15.

[0041] Since the hand wheel seat 5 is fixedly connected to the lens barrel 15 , a zero position mark can also be designed on the hand wheel seat 5 .

[0042] The handwheel buckle cover 6 is threadedly connected to the handwheel seat 5. When the handwheel buckle cover 6 is completely tightened on the handwheel seat 5, the second limit protrusion is aligned with the zero mark on the lens barrel 15. However, since the two are threadedly connected, there may be an error. Therefore, as a preferred embodiment, the top surface of the handwheel buckle cover 6 is evenly provided with a plurality of assembly screw holes 9 that match the limit screws 10 along the circumferential direction. Figure 2 As shown, the number of the assembly screw holes 9 is 4. When the handwheel buckle cover 6 is completely tightened on the handwheel seat 5, it only needs to be moved back 0-90° to obtain an assembly screw hole 9 aligned with the zero mark on the lens barrel 15. The adjustment range of the handwheel buckle cover 6 is small. Then, the limit screw 10 is placed in the assembly screw hole 9, and the handwheel buckle cover 6 is locked by glue or other means. In theory, the more the number of assembly screw holes 9, the better.

[0043] Specifically, the process of calibrating a firearm equipped with the scope is as follows: the stop ring 8 in the adjusting handwheel group on the scope is not installed, and the user actually hits point B when aiming at the center of the target point A. The position of the firearm is kept unchanged, and the adjusting handwheel 1 is pulled up to lift it, and the adjusting handwheel 1 is turned to make the actual impact point B in the scope lens coincide with the cross center point of the reticle; unscrew the zeroing screw 2 and remove the adjusting handwheel 1, install the stop ring 8, and tighten the stop ring 8 downward on the handwheel buckle cover 6 until the first limit protrusion 13 and the second limit protrusion form a limit, and install the adjusting handwheel 1 so that the linkage protrusion 11 is embedded in the linkage groove 12. At this time, the zero position of the scale mark on the outer wall of the adjusting handwheel 1 is aligned with the zero position mark on the lens barrel 15, that is, the adjusting handwheel group has been zeroed, and then the zeroing screw 2 is tightened, and the adjusting handwheel 1 is pressed down, and the adjusting handwheel 1 cannot be rotated at this time.

[0044] During subsequent use, the user can rotate the adjustment handwheel 1 according to the actual shooting conditions, and then only needs to rotate the adjustment handwheel 1 clockwise or counterclockwise until it cannot be rotated, so that the adjustment handwheel group can be quickly returned to zero; when other users use the firearm, they only need to rotate the adjustment handwheel 1 clockwise or counterclockwise until it cannot be rotated, so that the adjustment handwheel group can be quickly returned to zero.

[0045] Of course, the above are only preferred embodiments of the present invention, and are not intended to limit the scope of use of the present invention. Therefore, any equivalent changes made to the principles of the present invention should be included in the protection scope of the present invention.
