[0120] In the embodiment of the present application, the focus hand wheel 31 is connected to the lens assembly 22 through a transmission mechanism 40 including a connecting rod. By rotating the focus hand wheel 31, the transmission mechanism 40 can be driven to adjust the distance between the lens assembly 22 and the camera core 21 to achieve focusing. Compared with the objective end 20, the connecting housing 30 between the eyepiece end 10 and the objective end 20 is closer to the human eye. The focus hand wheel 31 is arranged on the connecting housing 30 of the sighting device.

[0122] In some embodiments of the present application, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, Figure 2 for Figure 1 An exploded view of the focusing hand wheel, the fixing seat, the control button knob and the hand wheel transmission structure in the sighting and aiming device of the first embodiment is shown; Figure 3 for Figure 1 A schematic diagram of the connection between the transmission mechanism, the focusing hand wheel and the focusing lens barrel in the sighting and aiming device of the first embodiment shown; Figure 4 for Figure 3 The schematic diagram of the connection between the focusing hand wheel, the hand wheel transmission structure and the main connecting rod is shown; Figure 5 for Figure 3The schematic diagram of the connection between the partial transmission mechanism and the focusing lens barrel shown in the figure; the rotation center axis of the focusing hand wheel 31 is perpendicular to the length direction of the connecting shell 30; the lens assembly 22 of the objective lens end 20 is installed in the lens housing 23; the transmission mechanism 40 includes: a hand wheel transmission structure 41, a main connecting rod 42 and an auxiliary connecting rod 43; the focusing hand wheel 31 is connected to the connecting shell 30 through a fixed seat 32; and the focusing hand wheel 31 is transmission-connected to the first end of the main connecting rod 42 through the hand wheel transmission structure 41; the second end of the main connecting rod 42 is connected to the auxiliary connecting rod 43; the auxiliary connecting rod 43 is connected to the lens assembly 22, and is used to drive the lens assembly 22 to move relative to the lens housing 23 to adjust the distance between the lens assembly 22 and the camera core 21; the main connecting rod 42 is installed in the connecting shell 30; the auxiliary connecting rod 43 extends from the connecting shell 30 into the lens housing 23 and is installed in the lens housing 23.

[0123] In the embodiment of the present application, the lens housing 23 protects the lens assembly 22 and prevents the lens assembly 22 from being damaged by bumps. During the focusing process, the focusing hand wheel 31 is rotated, and the hand wheel transmission mechanism 40, the main connecting rod 42 and the auxiliary connecting rod 43 are driven to realize the movement of the lens assembly 22 relative to the lens housing 23 to realize focusing.

[0124] In some embodiments of the present application, the tube diameter of the connecting shell 30 is smaller than the tube diameter of the lens housing 23; the main connecting rod 42 and the auxiliary connecting rod 43 are staggered, that is, the radial distance between the main connecting rod 42 and the front and rear center axis of the observation and aiming device is different from the radial distance between the auxiliary connecting rod 43 and the front and rear center axis of the observation and aiming device.

[0125] In the embodiment of the present application, since the barrel diameter of the connecting shell 30 is relatively small, the operator can hold the connecting shell 30 more firmly and comfortably; according to the structural setting inside the connecting shell 30 and the lens housing 23, the main connecting rod 42 and the auxiliary connecting rod 43 are staggered to minimize the influence of the transmission mechanism on the large barrel diameter of the lens housing and the small barrel diameter of the connecting shell.

[0129] In the embodiment of the present application, the focusing hand wheel 31 is arranged at the top of the connecting shell 30, and the rotation diameter of the focusing hand wheel 31 can be smaller than the diameter of the connecting shell 30.

The second sealing member is located between the connecting portion 2212 of the focusing lens barrel 221 and the lens housing 23, and provides a sliding seal between the connecting portion 2212 of the focusing lens barrel 221 and the lens housing 23, so as to prevent dust from entering the interior of the camera core 21 from between the lens housing 23 and the focusing lens barrel 221.

[0142] In some embodiments of the present application, Figure 1 , Figure 5 , Figure 6 and Figure 7As shown, the first sub-transmission mechanism 44 includes: a first driving gear 441 and a first driven wheel 442; the first end of the first driving gear 441 is fixedly connected to the second end of the auxiliary connecting rod 43, and the second end of the first driving gear 441 has a first external tooth; the first driven wheel 442 is located in the lens housing 23, and is partially sleeved on the outside of the connecting portion 2212 of the focusing lens barrel 221, and the inner wall circumference thereof is sequentially provided with a first internal tooth 4421 and a first internal thread in the direction away from the connecting shell 30; the first external tooth of the first driving gear 441 is meshed with the first internal tooth 4421 to drive the first driven wheel 442 to rotate; the outer wall of the connecting portion 2212 of the focusing lens barrel 221 is provided with a first external thread 22124 that cooperates with the first internal thread of the first driven wheel 442, so as to drive the focusing lens barrel 221 to slide in the lens housing 23 along the horizontal direction.

[0143] In the embodiment of the present application, since the first driving gear 441 is fixedly connected to the second end of the auxiliary connecting rod 43, and the auxiliary connecting rod 43 is transmission-connected to the main connecting rod 42, when the focusing hand wheel 31 is rotated, the main connecting rod 42 drives the auxiliary connecting rod 43 to rotate, and then drives the first driving gear 441 to rotate. Since the first driving gear 441 is meshed with the first internal tooth 4421 of the first driven wheel 442, the first driven wheel 442 rotates. Since the first internal thread of the first driven wheel 442 is also connected to the first external thread 22124 of the focusing barrel 221, and the first limiting portion 241 of the limiting member 24 limits the moving direction of the focusing barrel 221, the rotation of the first driven wheel 442 can drive the focusing barrel 221 to slide in the horizontal direction, thereby adjusting the distance between the optical lens in the focusing barrel 221 and the camera core 21, thereby achieving focusing.

[0144] Specifically, Figure 6 As shown, a first limiting step 4422 is provided on the first driven wheel 442 , and a side surface of the first limiting step 4422 abuts against the limiting member 24 .

More specifically, the number of the first limiting portions 241 can be the same as the number of the second limiting portions 22122, or the number of the first limiting portions 241 can be different from the number of the second limiting portions 22122. Figure 7 As shown, the number of the first limiting portions 241 may be two, and the number of the second limiting portions 22122 may also be two accordingly.

[0148] Specifically, the first limiting portion 241 can also be a limiting groove provided on the connecting portion 2212, the groove extending in the horizontal direction, and the second limiting portion 22122 is a limiting rod matched with the limiting groove.

[0150] In the embodiment of the present application, the annular groove 242 provides a storage space for the first drive gear 441 and the gear pressing plate 26, and the structure is more compact and space-saving. The first outer tooth portion of the first drive gear 441 is located in the avoidance notch 2411. The setting of the avoidance notch 2411 can prevent the first drive gear 441 from interfering with the annular groove 242 after rotation, thereby improving the reliability of the transmission process. The auxiliary connecting rod 43 passes through the gear pressing plate 26 and is fixedly connected to the first drive gear 441.
