The sight needs to carry out initial zeroing setting according to a certain shooting distance before leaving a factory, and is usually set according to a distance of 100m, in order to facilitate the sight to carry out zero marking on an adjusting device after carrying out initial zeroing setting, that is, a zero mark 323 on the adjusting device is aligned with a reference mark preset on a fixing device such as a sight fixing device, in this embodiment, as shown in fig. 2, the handwheel device 32 includes a handwheel body 321 and a zeroing adjusting piece 322 detachably connected with the handwheel body 321, and the handwheel body 321 and the zeroing adjusting piece 322 share a rotating shaft, the first connecting portion 34 is arranged on the outer surface of the zeroing adjusting piece 322, the accommodating hole 33 is arranged at the bottom of the zeroing adjusting piece 322, and the zeroing adjusting piece 322 is in threaded connection with the first connecting column 31 through the accommodating hole 33. Specifically, the hand wheel body 321 is provided with a zero position mark 323, when initial zero setting is required, the connection between the hand wheel body 321 and the zero setting adjusting part 322 is disconnected, so that the hand wheel body 321 does not rotate along with the rotation of the zero setting adjusting part 322, then the zero setting adjusting part 322 is rotated, so that the hand wheel body moves along the length direction of the first connecting column 31 by means of the engagement of the threads, thereby driving the bracket body 1 connected to the first connecting part 34 or the sighting device installed on the bracket body 1 to move together, so as to perform distance compensation adjustment on the sighting device, when the division center of the sighting device is overlapped with a set impact point or the target center of the target, after the zero position mark 323 of the hand wheel body 321 is aligned with a reference mark preset on a fixing device such as a sighting device, the hand wheel body 321 is assembled and connected with the zero setting adjusting part 322, so that the hand wheel body 321 and the zero setting adjusting part 322 can rotate together, therefore, zero marking is completed, and the method is convenient and quick and can be flexibly applied to zero setting of various shooting distances.

It should be noted that, in this embodiment, the way of the detachable connection between the handwheel body 321 and the return-to-zero adjusting part 322 is not limited, as long as the handwheel body 321 and the return-to-zero adjusting part 322 can be disassembled and assembled as required. For example, as shown in fig. 1 and fig. 2, in order to facilitate the processing and assembling of parts and reduce the structural height, the zeroing adjustment element 322 and the handwheel body 321 are movably sleeved on the first connecting post 31, the zeroing adjustment element 322 and the handwheel body 321 are connected in a nested manner, the handwheel body 321 is provided with at least one first pin 324 facing the zeroing adjustment element 322, the first pin 324 is detachably connected to the handwheel body 321, and one end of the first pin 324 abuts against the outer side wall of the zeroing adjustment element 322. In this embodiment, the first pin 324 is in threaded connection with the handwheel body 321, and when the first pin 324 is tightly abutted against the outer side wall of the return-to-zero adjusting piece 322 by screwing up the threads, the return-to-zero adjusting piece 322 is connected with the handwheel body 321 by virtue of the contact friction force between the first pin 324 and the return-to-zero adjusting piece 322; the return-to-zero adjusting piece 322 can be disconnected from the handwheel body 321 by unscrewing the first pin 324 to remove the first pin from contact with the return-to-zero adjusting piece 322. In addition, if the return-to-zero adjusting piece 322 has a fault, such as a thread slipping, the return-to-zero adjusting piece 322 can be separated from the hand wheel body 321 by removing the first pin 324, so that the return-to-zero adjusting piece 322 can be replaced, and maintenance of parts is facilitated.

Further, in order to ensure that the return-to-zero adjusting element 322 is more reliably connected with the handwheel body 321 in the rotating process, in this embodiment, as shown in fig. 1 and fig. 2, at least one elongated groove 325 is disposed on an outer side wall of the return-to-zero adjusting element 322, the elongated groove 325 extends along a rotation center line of the return-to-zero adjusting element 322, and one end of the first pin 324 abuts against an inner wall of the elongated groove 325. Because the inner wall of the elongated groove 325 can block the first pin 324 from sliding along the circumferential direction of the return-to-zero adjusting part 322, the return-to-zero adjusting part 322 can be prevented from sliding along the circumferential direction in the process of rotating the handwheel body 321, and the connection between the handwheel body 321 and the return-to-zero adjusting part 322 is more reliable. To facilitate the assembly of the first pins 324 with the elongated grooves 325, in this embodiment, a plurality of elongated grooves 325 are uniformly spaced along the outer sidewall of the handwheel body 321.

In order to facilitate the assembly of the first pin 324 and the elongated groove 325, in the embodiment, as shown in fig. 2, one end of the first pin 324 facing the elongated groove 325 is tapered, and a small end of the taper faces the elongated groove 325. The cross section of the elongated groove 325 is a structure with a small bottom and a large top, and the taper shape is matched with the cross section of the elongated groove 325, so that the first pin 324 can more easily extend into the elongated groove 325 and abut against the inner wall of the elongated groove 325 in the screwing process.

As shown in fig. 1 and 2, an annular groove 327 is further disposed on an outer sidewall of the return-to-zero adjusting element 322, a rotation center line of the annular groove 327 is parallel to a rotation center line of the return-to-zero adjusting element 322, the hand wheel body 321 is further provided with at least one second pin 326 facing the annular groove 327, the second pin 326 is in threaded connection with the hand wheel body 321, one end of the second pin 326 is provided with an embedding portion 3261 capable of being embedded into the annular groove 327, and two opposite inner walls of the annular groove 327 are in contact connection with the embedding portion 3261. Since the second pin 326 can slide along the annular groove 327, the second pin 326 does not need to be screwed when performing zero position marking, and the second pin 326 can be used to carry the non-rotating adjustment member 322 along the length of the first connecting column 31. In addition, if the return-to-zero adjusting piece 322 has a fault, such as a thread slipping, the return-to-zero adjusting piece 322 can be separated from the hand wheel body 321 by removing the second pin 326, so that the return-to-zero adjusting piece 322 can be replaced, and maintenance of parts is facilitated.

In other embodiments not shown in the figures, the handwheel body 321 may be detachably connected to the zero adjustment member 322 by a latch.

Because of the influence of the machining precision and the machining error of the threads, a radial gap exists between the threads which are meshed with each other, and the radial gap causes the phenomenon that the hand wheel device 32 and the first connecting column 31 which are connected through the threads are loosened or shaken in the radial direction, so that the stability of the hand wheel device 32 during rotation is influenced, and the aiming precision of an aiming tool connected with the hand wheel device 32 is further influenced. In order to eliminate the looseness or the wobbling phenomenon and further improve the stability of the handwheel device 32 during rotation, in the present embodiment, as shown in fig. 1 and fig. 2, the receiving hole 33 further includes a non-threaded hole 332 concentric with the female threaded hole 331, and the non-threaded hole 332 is in clearance fit with the first connecting column 31. Specifically, as shown in fig. 1, the unilateral radial clearance when the non-threaded hole 332 is in clearance fit with the first connection post 31 is less than or equal to 0.05mm, and the clearance fit mode includes:

(a) the first connecting column 31 comprises a polished rod section 312 matched with a non-threaded hole 332, the non-threaded hole 332 is in clearance fit with the polished rod section 312, and the unilateral radial clearance in clearance fit is less than or equal to 0.05 mm. Because the fit clearance between the non-threaded hole 332 of the accommodating hole 33 and the polished rod section 312 of the first connecting post 31 is small, the radial looseness or the shake existing when the internal threaded hole 331 of the accommodating hole 33 is meshed and connected with the external thread of the first connecting post 31 can be restrained, and the stability of the handwheel device 32 during rotation can be further improved.

(b) The non-threaded hole 332 is in clearance fit with the external thread of the first connecting column 31, and a single-side radial clearance between the inner diameter of the non-threaded hole 332 and the thread major diameter of the external thread is less than or equal to 0.05 mm. Because the fit clearance between the non-threaded hole 332 of the accommodating hole 33 and the external thread of the first connecting column 31 is small, radial looseness or shaking existing when the internal threaded hole 331 of the accommodating hole 33 is meshed and connected with the external thread of the first connecting column 31 can be restrained, and therefore stability of the handwheel device 32 during rotation can be further improved.

In the present embodiment, the position of the non-threaded hole 332 with respect to the female screw hole 331 is not limited as long as the non-threaded hole 332 and the female screw hole 331 are concentric. For example, the non-threaded hole 332 may be located above the internal threaded hole 331, or may be located below the internal threaded hole 331.

Specifically, in this embodiment, the hand wheel connection member 328 and the hand wheel body 321 are independent from each other and movable, when the hand wheel device 32 needs to be connected to the bracket body 1 through the first connection portion 34, the outer flange 341 on the outer side wall of the hand wheel connection member 328 and the outer flange 341 on the outer side wall of the hand wheel body 321 are first in contact connection with the bracket body 1, for example, the two outer flanges 341 are in contact connection with the top surface and the bottom surface of the bracket body 1, which is equivalent to clamping the bracket body 1 through the two outer flanges 341, and then the hand wheel connection member 328 is fixedly connected to the hand wheel body 321, so that the bracket body 1 can move along with the hand wheel device 32 without limiting the rotation of the hand wheel. Such a structure not only facilitates quick installation of the outer flange 341 but also ensures contact connection of the outer flange 341 with the holder body 1, eliminating a gap between the outer flange 341 and the holder body 1.

In addition, the moving direction of the first adjusting shaft 42 may be set by the screw thread direction, and the distance moved per rotation of the first adjusting shaft 42 may be changed by changing the pitch of the screw thread. Therefore, the connection mode of the first adjusting shaft 42 and the second connecting column 41 can make the first adjusting shaft 42 move directionally and quantitatively, so that the first adjusting shaft 42 moves in a reciprocating manner more stably and the displacement is more accurate and controllable.

It should be noted that, the structure of the connection protrusion 431 is not limited in this embodiment, as long as the connection protrusion 431 can be inserted into the annular groove 422 and drive the second connection portion 43 to move along with the first adjustment shaft 42. For example, as shown in fig. 4, the connecting protrusion 431 may be an independently movable connecting piece, and the connecting piece may be first inserted into the annular groove 422, and then the connecting piece is fixedly connected to the second connecting portion 43, so that the second connecting portion 43 is connected to the first adjusting shaft 42; alternatively, in an embodiment not shown in the drawings, the connection protrusion 431 may be a second pin 326 which is independently movable, the second pin 326 is in threaded connection with the second connection portion 43, and the second pin 326 faces the outer circumferential edge of the first adjustment shaft 42, the second connection portion 43 and the first adjustment shaft 42 may be positioned first, and then the second pin 326 is screwed down to make one end of the second pin embed into the annular groove 422 and contact and connect with the inner sidewall of the annular groove 422, so that the second connection portion 43 and the first adjustment shaft 42 can be connected.

Specifically, because first regulation axle 42 all is connected with second spliced pole 41 and second connecting portion 43, consequently at second spliced pole 41 with set up first elastic component 44 between the second connecting portion 43, come the threaded connection of tensioning first regulation axle 42 and second spliced pole 41 through the elasticity of first elastic component 44, the contact of the thread of internal and external screw thread is more inseparabler in the axial during threaded connection, thereby eliminate the phenomenon that the screw thread is not hard up or rocks through the frictional force between the adjacent thread of increase, stability when further improving first regulation axle 42 and rotate. Preferably, the first elastic member 44 is a spring, particularly a wave spring.

In order to facilitate the rotation operation of the first adjusting shaft 42, in this embodiment, as shown in fig. 4, the optical adjustment hinge structure further includes an adjusting handwheel 45, the adjusting handwheel 45 is connected to the first adjusting shaft 42, and the adjusting handwheel 45 can drive the first adjusting shaft 42 to rotate around the rotation center line of the first adjusting shaft 42. It should be noted that the structure of the adjusting handwheel 45 is not limited in this embodiment, as long as the structure of the adjusting handwheel 45 is beneficial to the rotating operation. For example, the adjusting hand wheel 45 is a cylinder with a diameter larger than that of the first adjusting shaft 42, patterns are pressed on the outer periphery of the cylinder to increase the gripping friction force during the rotation operation, and the adjusting hand wheel 45 is sleeved and connected with the first adjusting shaft 42; alternatively, the adjustment hand wheel 45 may be a polygonal cylinder. In addition, the connection manner between the adjusting hand wheel 45 and the first adjusting shaft 42 is not limited in this embodiment, as long as the adjusting hand wheel 45 can drive the first adjusting shaft 42 to rotate.

In order to facilitate zero marking of the adjusting device after initial zero resetting of the sight and processing and assembling of parts, in this embodiment, the adjusting hand wheel 45 is detachably connected to the first adjusting shaft 42, that is, the adjusting hand wheel 45 and the first adjusting shaft 42 can be disassembled and assembled as required. For example, as shown in fig. 4 and 5, the adjusting handwheel 45 is sleeved on the first adjusting shaft 42, the adjusting handwheel 45 is provided with at least one first pin 324 facing the first adjusting shaft 42, the first pin 324 is detachably connected to the adjusting handwheel 45, and one end of the first pin 324 abuts against an outer side wall of the first adjusting shaft 42. In this embodiment, the first pin 324 is in threaded connection with the adjusting hand wheel 45, and when the first pin 324 is tightly abutted against the outer side wall of the first adjusting shaft 42 by screwing up the threads, the first adjusting shaft 42 and the adjusting hand wheel 45 are connected together by means of the contact friction force between the first pin 324 and the first adjusting shaft 42; the first adjustment shaft 42 may be disconnected from the adjustment hand wheel 45 by unscrewing the threads to release the first pin 324 from contact with the first adjustment shaft 42.

Further, in order to make the connection between the adjusting handwheel 45 and the first adjusting shaft 42 more reliable, in this embodiment, as shown in fig. 4 and 5, at least one elongated groove 325 is disposed on an outer side wall of the first adjusting shaft 42, which is matched with the adjusting handwheel 45, a length of the elongated groove 325 extends along a length direction of the first adjusting shaft 42, and one end of the first pin 324 abuts against an inner wall of the elongated groove 325. Because the inner wall of the elongated groove 325 can block the first pin 324 from sliding along the circumferential direction of the first adjusting shaft 42, the first adjusting shaft 42 can be prevented from sliding along the circumferential direction in the process of rotating along with the adjusting hand wheel 45, and the connecting between the adjusting hand wheel 45 and the first adjusting shaft 42 is more reliable. In this embodiment, the plurality of elongated grooves 325 are uniformly spaced along the outer side wall of the first adjusting shaft 42.

Further, in order to prevent the adjusting hand wheel 45 from sliding along the length direction of the first adjusting shaft 42 during the use process, thereby affecting the adjusting operation, in this embodiment, as shown in fig. 4 and 5, an annular groove 327 is further provided on an outer side wall of the first adjusting shaft 42, a rotation center line of the annular groove 327 is parallel to a rotation center line of the first adjusting shaft 42, the adjusting hand wheel 45 is further provided with at least one second pin 326 facing the annular groove 327, the second pin 326 is in threaded connection with the adjusting hand wheel 45, one end of the second pin 326 is provided with an embedding portion 3261 capable of being embedded into the annular groove 327, and two opposite inner walls of the annular groove 327 are in contact connection with the embedding portion 3261. Since the second pin 326 is slidable along the annular groove 327, the second pin 326 is not rotated when performing the zero position marking, and the second pin 326 is used to carry the adjusting hand wheel 45 along with the first adjusting shaft 42 without rotating. In addition, if the adjusting hand wheel 45 has a fault, the second pin 326 can be removed, so that the first adjusting shaft 42 is separated from the adjusting hand wheel 45, the adjusting hand wheel 45 can be replaced, and maintenance of parts is facilitated.

Alternatively, in an embodiment not shown in the figures, the first adjustment shaft 42 is screwed to the adjustment handwheel 45. Specifically, when the adjusting hand wheel 45 is assembled with the first adjusting shaft 42, the adjusting hand wheel 45 is connected with the first adjusting shaft 42 through threaded engagement, then the first pin 324 is installed on the adjusting hand wheel 45, and the first adjusting shaft 42 is connected with the adjusting hand wheel 45 by means of contact friction force between the first pin 324 and the first adjusting shaft 42. The engagement of the first pin 324 with the elongated groove 325 may prevent the adjustment hand wheel 45 from sliding along the circumference of the first adjustment shaft 42 during use, and the threaded connection may further prevent the adjustment hand wheel 45 from sliding along the length of the first adjustment shaft 42 during use.

In other embodiments not shown in the figures, the adjustment hand wheel 45 may be detachably connected to the first adjustment shaft 42 by a latch.

In the present embodiment, the initial zeroing setting of the optical adjustment hinge structure is as follows: the adjusting hand wheel 45 is provided with a zero mark 323, when initial zero setting is needed, the adjusting hand wheel 45 is disconnected with the first adjusting shaft 42, so that the adjusting hand wheel 45 does not rotate along with the rotation of the first adjusting shaft 42, then the first adjusting shaft 42 is rotated, so that the adjusting hand wheel is penetrated and arranged on the second connecting column 41 in a reciprocating manner by means of threaded engagement, and the bracket body 1 connected with the second connecting part 43 or the sighting device arranged on the bracket body 1 is driven to move together, thereby carrying out wind offset compensation adjustment on the sighting device, when the division center of the sighting device is superposed with a set impact point or the target center of a target, the zero mark 323 of the adjusting hand wheel 45 is aligned with a reference mark which is preset on a fixing device such as a sighting device, then the adjusting hand wheel 45 is assembled and connected with the first adjusting shaft 42, so that the adjusting hand wheel 45 and the first adjusting shaft 42 can rotate together, thereby completing the zero marking, the wind speed control method is convenient and fast, and can be flexibly applied to return-to-zero setting under various wind speed modes.

As shown in fig. 6, in another embodiment of an optical adjustment hinge structure, the difference from the above-mentioned embodiment of an optical adjustment hinge structure is that the second connecting column 41 includes an upper column 411 and a lower column 412 having a common rotating shaft 413, and the upper column 411 and the lower column 412 are both rotatable around the common rotating shaft 413, the internal threaded through hole is provided in the upper column 411, and a center line of the internal threaded through hole is perpendicular to a length direction of the upper column 411 and parallel to a center line of the common rotating shaft 413, and the first adjustment shaft 42 is inserted through the upper column 411 by internal and external thread engagement.

Because the front end of the bracket body 1 is constrained by the second connecting column 41 and the first adjusting shaft 42, when the hand wheel device 32 drives the bracket body 1 to reciprocate along the length direction of the first connecting column 31, the bracket body 1 is actually turned over along the direction away from or close to the bracket base 2 around the first adjusting shaft 42, and because the lower end of the first connecting column 31 can slide along the direction towards or away from the front end of the bracket body 1, the central line of the external thread of the first connecting column 31 can be ensured to be always tangent to the turning track of the bracket body 1 around the first adjusting shaft 42, and the locking of the zeroing adjusting piece 322 and the first connecting column 31 in the process of thread engagement is prevented. The adjusting stroke of the adjusting bracket can be changed by changing the installation distance between the first connecting column 31 and the second connecting column 41, and the larger the installation distance between the first connecting column 31 and the second connecting column 41 is, the larger the adjustable stroke of the adjusting bracket is.

Preferably, the second elastic member 92 is a spring.

Further, as shown in fig. 8 and 10, the second elastic member 92 is sleeved on the first connection column 31, and two ends of the second elastic member 92 respectively abut against the support base 2 and the hand wheel device 32, so as to prevent the second elastic member 92 from being separated from the support base 2 or the support body 1 due to vibration during the use of the adjusting support, and the first connection column 31 can guide the movement direction of the second elastic member 92 during compression or extension, so that the second elastic member 92 is compressed or extended along the length direction of the first connection column 31.
