[0118] In the embodiment of the present application, the focus hand wheel 13 is connected to the lens assembly 22 through a transmission mechanism 40 including a connecting rod. By rotating the focus hand wheel 13, 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 eyepiece end 10 is closer to the human eye. The focus hand wheel 13 is arranged at the eyepiece end 10 of the sighting device.

The transmission mechanism 40 also includes: a first sub-transmission mechanism 43. The first sub-transmission mechanism 43 is respectively connected to the second end of the first auxiliary connecting rod 42 and the connecting portion 2212 of the focusing lens barrel 221, so as to convert the rotation force of the first auxiliary connecting rod 42 into a horizontal pulling force, thereby driving the focusing lens barrel 221 to slide in the lens housing 23 along the horizontal direction.

[0128] In the embodiment of the present application, the lens mounting portion 2211 of the focusing lens barrel 221 can accommodate the lens, and the focusing lens barrel 221 is adjusted to move in the horizontal direction, that is, the lens located in the focusing lens barrel 221 is adjusted to move, so as to achieve focusing. The first limiting portion 241 of the limiting member 24 can limit the sliding direction of the focusing lens barrel 221, improve the accuracy and stability of the sliding of the focusing lens barrel 221, and thus improve the accuracy of focusing. The first sub-transmission mechanism 43 can convert the rotational force of the first auxiliary connecting rod 42 into a horizontal pulling force, drive the focusing lens barrel 221 to slide horizontally, and adjust the distance between the optical lens in the focusing lens barrel 221 and the camera core 21. Among them, since the first sub-transmission mechanism 43 can convert the rotational force of the first auxiliary connecting rod 42 into a horizontal pulling force, the first auxiliary connecting rod 42 does not move, thereby reducing interference with other components and improving the stability of transmission.

[0129] Specifically, the connecting portion 2212 is provided with a first sealing groove 22123, and the sighting device further includes a first sealing member (not shown), which is arranged in the first sealing groove 22123. The first 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.

[0130] In some embodiments of the present application, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the first sub-transmission mechanism 43 includes: a first driving gear 431 and a first driven wheel 432; the first end of the first driving gear 431 is fixedly connected to the second end of the first auxiliary connecting rod 42, and the second end of the first driving gear 431 has a first external tooth; the first driven wheel 432 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 4321 and a first internal thread (not shown) in the direction away from the connecting shell 30; the first external tooth of the first driving gear 431 is meshed with the first internal tooth 4321 to drive the first driven wheel 432 to rotate; the outer wall of the connecting portion 2212 of the focusing lens barrel 221 is provided with a first external thread 2213 matched with the first internal thread of the first driven wheel 432, so as to drive the focusing lens barrel 221 to slide in the lens housing 23 along the horizontal direction.

[0131] In the embodiment of the present application, since the first driving gear 431 is fixedly connected to the second end of the first auxiliary connecting rod 42, and the first auxiliary connecting rod 42 is transmission-connected to the main connecting rod 41, when the focusing hand wheel 13 is rotated, the main connecting rod 41 drives the first auxiliary connecting rod 42 to rotate, and then drives the first driving gear 431 to rotate. Since the first driving gear 431 is meshed with the first internal teeth 4321 of the first driven wheel 432, the first driven wheel 432 rotates. Since the first internal thread of the first driven wheel 432 is also connected to the first external thread 2213 of the focusing barrel 221, and the first limiting portion of the limiting member 24 limits the moving direction of the focusing barrel 221, the rotation of the first driven wheel 432 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.

[0132] In some embodiments of the present application, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the connecting portion 2212 of the focusing lens barrel 221 includes: a threaded portion 22121 and a second limiting portion 22122; the first external thread 2213 is arranged on the outer periphery of the threaded portion 22121 and cooperates with the first internal thread of the first driven wheel 432; the second limiting portion 22122 cooperates with the first limiting portion 241; and a first elastic member 25 is arranged between the second limiting portion 22122 and the limiting member 24.

[0133] In the embodiment of the present application, the first elastic member 25 is arranged between the limit member 24 and the focusing lens barrel 221. When the limit member 24 and the focusing lens barrel 221 are assembled, the first elastic member 25 is in a compressed state. Under the action of the elastic force of the first elastic member 25, the axial gap of the thread between the focusing lens barrel 221 and the first driven wheel 432 can be eliminated.

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 3 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.

[0135] 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. The present application does not limit the shapes of the first limiting portion 241 and the second limiting portion 22122.

[0136] Specifically, Figure 4 As shown, a first limiting step 4322 is provided on the first driven wheel 432 , and a side surface of the first limiting step 4322 abuts against the limiting member 24 .

[0138] In the embodiment of the present application, the annular groove 242 provides a storage space for the first drive gear 431 and the gear pressure plate 26, and the structure is more compact and space-saving. The first outer tooth portion of the first drive gear 431 is located in the notch 2421. The setting of the notch 2421 can prevent the first drive gear 431 from interfering with the annular groove 242 after rotation, thereby improving the reliability of the transmission process. The first auxiliary connecting rod 42 passes through the gear pressure plate 26 and is fixedly connected to the first drive gear 431. The gear pressure plate 26 can provide support for the first auxiliary connecting rod 42, which can reduce the probability of the first auxiliary connecting rod 42 breaking near the first drive gear 431.

When the focusing hand wheel 13 is rotated, the main connecting rod 41 drives the first auxiliary connecting rod 42 to rotate. Since the shaft sleeve 434 is fixedly connected to the focusing lens barrel 221 through threads, and the first limiting portion of the limiting member limits the moving direction of the focusing lens barrel 221, the focusing lens barrel 221 can be slid in the horizontal direction, thereby adjusting the distance between the optical lens in the focusing lens barrel 221 and the camera core 21, thereby achieving focusing.
