[0118] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art based on this application are within the scope of protection of this application.
[0119] To address the problems of arduous focusing and poor comfort in existing observation and aiming devices, embodiments of this application provide an observation and aiming device, such as... Figure 1 As shown, Figure 1This is a partial cross-sectional view of the aiming and viewing device according to the first embodiment of this application. The aiming and viewing device includes: an eyepiece end 10 and an objective lens end 20, which are connected by a cylindrical connecting housing 30. The eyepiece end 10 and the objective lens end 20 are located at opposite ends of the length of the connecting housing 30. The eyepiece end 10 is provided with an eyepiece assembly 11. The objective lens end 20 is provided with a camera core 21 and a lens assembly 22. The camera core 21 is located on the side of the lens assembly 22 facing the eyepiece end 10. A focusing handwheel 31 is provided on the connecting housing 30. The focusing handwheel 31 is connected to the lens assembly 22 of the objective lens end 20 via a transmission mechanism 40 including a connecting rod, so that the rotation of the focusing handwheel 31 drives the transmission mechanism 40 to adjust the distance between the lens assembly 22 and the camera core 21. Among them, part of the connecting rod of the transmission mechanism 40 passes through the connecting housing 30 at the position corresponding to the focusing handwheel 31 and extends to the objective lens end 20 to be connected to the lens assembly 22.
[0120] In this embodiment, the focusing handwheel 31 is connected to the lens assembly 22 via a transmission mechanism 40 including a linkage. By rotating the focusing handwheel 31, the transmission mechanism 40 can be driven to adjust the distance between the lens assembly 22 and the camera core 21, thereby achieving focusing. Compared to the objective lens end 20, the connecting housing 30 between the eyepiece end 10 and the objective lens end 20 is closer to the human eye. By placing the focusing handwheel 31 on the connecting housing 30 of the viewing device, the operator does not need to extend their hand a long distance when focusing, making the focusing process more effortless and more comfortable.
[0121] Specifically, such as Figure 1 As shown, the eyepiece assembly includes an eyepiece knob 111, an eyepiece lens 112, an eyepiece display screen (not shown), and a data cable interface 113. By rotating the eyepiece knob 111, the distance between the eyepiece lens 112 and the eyepiece display screen can be adjusted. The data cable interface 113 is used to connect to external devices via a data cable.
[0122] In some embodiments of this application, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, Figure 2 for Figure 1 An exploded view of the focusing handwheel, fixed base, control button knob, and handwheel transmission structure in the observation and aiming device of the first embodiment shown; Figure 3 for Figure 1 A schematic diagram showing the connection between the transmission mechanism, the focusing handwheel, and the focusing lens barrel in the first embodiment of the observation and aiming device shown; Figure 4 for Figure 3 The diagram shows the connection between the focusing handwheel, the handwheel transmission structure, and the main connecting rod. Figure 5 for Figure 3The diagram shows the connection between the transmission mechanism and the focusing lens barrel; the rotation axis of the focusing handwheel 31 is perpendicular to the length direction of the connecting housing 30; the lens assembly 22 of the objective lens end 20 is installed inside the lens housing 23; the transmission mechanism 40 includes: a handwheel transmission structure 41, a main connecting rod 42, and an auxiliary connecting rod 43; the focusing handwheel 31 is connected to the connecting housing 30 through a fixed base 32; and the focusing handwheel 31 is connected to the first end of the main connecting rod 42 through the handwheel 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 inside the connecting housing 30; the auxiliary connecting rod 43 extends from the connecting housing 30 and is installed inside the lens housing 23.
[0123] In this embodiment, the lens housing 23 protects the lens assembly 22 from impacts and damage. During focusing, rotating the focusing handwheel 31, through the handwheel transmission mechanism 40, the main connecting rod 42, and the auxiliary connecting rod 43, moves the lens assembly 22 relative to the lens housing 23, thus achieving focusing.
[0124] In some embodiments of this application, the diameter of the connecting housing 30 is smaller than the diameter of the lens housing 23; the main connecting rod 42 and the auxiliary connecting rod 43 are misaligned, that is, the radial distance between the main connecting rod 42 and the front and rear central axis of the aiming device is different from that between the auxiliary connecting rod 43 and the front and rear central axis of the aiming device.
[0125] In this embodiment, since the diameter of the connecting housing 30 is small, the operator can hold the connecting housing 30 more securely and comfortably. According to the internal structure of the connecting housing 30 and the lens housing 23, the main connecting rod 42 and the auxiliary connecting rod 43 are staggered to minimize the impact of the transmission mechanism on the large diameter of the lens housing and the small diameter of the connecting housing.
[0126] In some embodiments of this application, the main connecting rod 42 is disposed near the edge of the connecting housing 30, and the auxiliary connecting rod 43 is disposed near the lens housing 23 and spaced apart from the camera core 21.
[0127] In some embodiments of this application, the connecting housing 30 includes a main barrel portion 30a, the diameter of which is smaller than the diameter of the lens housing 23; the main barrel portion 30a extends into a connecting portion 30b with a gradually increasing diameter towards the objective lens end, the connecting portion 30b being used to connect with the lens housing 23; the main connecting rod 41 and the first auxiliary connecting rod 42 are staggered at the connecting portion 30b, which can make full use of the space of the gradually increasing diameter of the connecting portion 30b.
[0128] In some embodiments of this application, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the fixed base 32 is embedded in the inner side of the top wall of the connecting housing 30; the handwheel transmission structure 41 includes: a first bevel gear 411 and a second bevel gear 412; the first bevel gear 411 is disposed inside the focusing handwheel 31 and is coaxially connected to the focusing handwheel 31; the second bevel gear 412 is disposed on the side of the fixed base 32 facing the objective lens end 20 and is fixedly connected to the first end of the main connecting rod 42; it is used to mesh with the first bevel gear 411 to drive the main connecting rod 42 to rotate.
[0129] In this embodiment, the focusing handwheel 31 is located on the top of the connecting housing 30. The rotation diameter of the focusing handwheel 31 can be smaller than the diameter of the connecting housing 30. The smaller the rotation diameter, the less effort is required to rotate it by hand, thus making the focusing process more effortless and further improving the comfort of focusing. The first bevel gear 411 is fixedly connected to the focusing handwheel 31, and the second bevel gear 412 is fixedly connected to the main connecting rod 42. The first bevel gear 411 and the second bevel gear 412 mesh and their rotation axes are perpendicular. Rotating the focusing handwheel 31 allows the transmission direction to be changed through the first bevel gear 411 and the second bevel gear 412. Gear transmission has the advantages of smooth transmission, precise transmission ratio, high reliability, high transmission efficiency, long service life, and compact structure. Therefore, the cooperative transmission of the first bevel gear 411 and the second bevel gear 412 enables the focusing process to be precise, efficient, and reliable, which can extend the service life of the observation and aiming equipment, improve the compactness of the internal structure of the observation and aiming equipment, and reduce the size of the equipment.
[0130] Specifically, such as Figure 2 As shown, the first bevel gear 411 can be fixedly connected to the focusing handwheel 31 via the first connecting piece 4111, which can be a screw.

[0132] In this embodiment, the first handwheel limiting plate 33 is fixedly connected to the fixed base 32, and the focusing handwheel 31 is sleeved on the first handwheel limiting plate 33.

[0135] In the embodiments of this application, such as Figure 2 As shown, the height of the first connecting boss 321 is greater than the height of the outer wall 322 of the fixed seat. The first connecting boss 321 can extend upward and be fixedly connected to the first handwheel limiting plate 33. The outer wall 322 of the fixed seat is fixedly connected to the connecting housing 30. The fixed seat 32 serves to connect the first handwheel limiting plate 33 and the connecting housing 30.
[0136] In some embodiments of this application, such as Figure 2 As shown, a first mounting groove 323 is formed between the first connecting boss 321 inside the mounting base 32 and the outer wall 322 of the mounting base, and the first bevel gear 411 is installed in the first mounting groove 323; a first mounting notch 324 is provided on the outer wall of the mounting base 32 facing the objective lens end 20; the second bevel gear 412 is installed in the first mounting notch 324 to mesh with the first bevel gear 411.
[0137] In this embodiment, the first bevel gear 411 is located in the first mounting groove 323. The first mounting groove 323 can prevent the first bevel gear 411 from interfering with the fixed seat 32 during the rotation of the focusing handwheel 31, thereby ensuring the smooth progress of the focusing process.
[0138] Specifically, such as Figure 2 As shown, a bevel gear pressure plate 326 is provided at the first mounting notch 324.

[0139] In some embodiments of this application, such as Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, Figure 6 for Figure 3 A cross-sectional view of the internal structure of the lens housing shown; Figure 7 for Figure 6 The exploded view of the internal structure of the lens housing is shown; the lens assembly 22 has a focusing lens barrel 221; the focusing lens barrel 221 includes: a lens mounting part 2211 and a connecting part 2212; the lens mounting part 2211 is located inside the lens housing 23 on the side away from the connecting housing 30, and is used to mount the lens inside and to cooperate with the lens housing 23 outside; the connecting part 2212 is connected to the lens housing 23 by a limiting member 24; the limiting member 24 is disposed between the camera core 21 and the focusing lens barrel 221; the limiting member 24 and the lens housing The lens housing 23 is fixedly connected and has a first limiting part 241. The first limiting part 241 is slidably connected to the connecting part 2212 of the focusing lens barrel 221 to limit the sliding distance of the focusing lens barrel 221 in the horizontal direction within the lens housing 23. The transmission mechanism 40 further includes: a first sub-transmission mechanism 44. The first sub-transmission mechanism 44 is respectively connected to the second end of the auxiliary connecting rod 43 and the connecting part 2212 of the focusing lens barrel 221, so that the auxiliary connecting rod 43 drives the focusing lens barrel 221 to slide in the horizontal direction within the lens housing 23.
[0140] In this embodiment, the lens mounting portion 2211 of the focusing lens barrel 221 can accommodate a lens. By adjusting the horizontal movement of the focusing lens barrel 221, that is, adjusting the movement of the lens located within the focusing lens barrel 221, focusing is achieved. The first limiting portion 241 of the limiting member 24 can limit the sliding direction of the focusing lens barrel 221, improving the accuracy and stability of the sliding of the focusing lens barrel 221, thereby improving the accuracy of focusing. The first sub-transmission mechanism 44 can transmit the movement of the auxiliary connecting rod 43 to the focusing lens barrel 221, thereby adjusting the distance between the optical lens and the camera core 21 in the focusing lens barrel 221.
[0141] Specifically, the connecting portion 2212 is provided with a second sealing groove 22123, and the viewing device also includes a second sealing element (not shown), with the first sealing element disposed within the second sealing groove 22123. The second sealing element is located between the connecting portion 2212 of the focusing lens barrel 221 and the lens housing 23, providing a sliding seal between the connecting portion 2212 of the focusing lens barrel 221 and the lens housing 23, preventing dust from entering the camera core 21 from between the lens housing 23 and the focusing lens barrel 221.
[0142] In some embodiments of this application, such as Figure 1 , Figure 5 , Figure 6 and Figure 7As shown, the first sub-transmission mechanism 44 includes: a first drive gear 441 and a first driven wheel 442; the first end of the first drive gear 441 is fixedly connected to the second end of the auxiliary connecting rod 43, and the second end of the first drive gear 441 has a first external tooth; the first driven wheel 442 is located inside the lens housing 23 and is partially sleeved outside the connecting part 2212 of the focusing lens barrel 221, and its inner wall circumferential side is provided with a first internal tooth 4421 and a first internal thread in sequence along the direction away from the connecting housing 30; the first external tooth of the first drive gear 441 meshes with the first internal tooth 4421 to drive the first driven wheel 442 to rotate; the outer wall of the connecting part 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 to drive the focusing lens barrel 221 to slide horizontally inside the lens housing 23.
[0143] In this embodiment, since the first drive gear 441 is fixedly connected to the second end of the auxiliary connecting rod 43, and the auxiliary connecting rod 43 is connected to the main connecting rod 42, when the focusing handwheel 31 is rotated, the main connecting rod 42 drives the auxiliary connecting rod 43 to rotate, which in turn drives the first drive gear 441 to rotate. Since the first drive gear 441 meshes 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 lens barrel 221, and the first limiting part 241 of the limiting member 24 limits the movement direction of the focusing lens barrel 221, the rotation of the first driven wheel 442 can drive the focusing lens barrel 221 to slide in the horizontal direction, thereby adjusting the distance between the optical lens inside the focusing lens barrel 221 and the camera core 21, thus achieving focusing.
[0144] Specifically, such as Figure 6 As shown, the first driven wheel 442 is provided with a first limiting step 4422, and the side of the first limiting step 4422 abuts against the limiting member 24.
[0145] In some embodiments of this application, the connecting portion 2212 of the focusing lens barrel 221 includes: a threaded portion 22121 and a second limiting portion 22122; a first external thread 22124 is disposed on the outer periphery of the threaded portion 22121 and engages with the first internal thread of the first driven wheel 442; the second limiting portion 22122 engages with the first limiting portion 241; and an elastic member 25 is disposed between the connecting portion and the limiting member 24.
[0146] In this embodiment, the elastic element 25 is disposed between the limiting element 24 and the focusing lens barrel 221. After the limiting element 24 and the focusing lens barrel 221 are assembled, the elastic element 25 is in a compressed state. Under the elastic force of the elastic element 25, the axial gap of the thread between the focusing lens barrel 221 and the first driven wheel 442 can be eliminated.
[0147] Specifically, the threaded portion 22121 is an arc-shaped threaded portion 22121, which facilitates engagement with the first internal thread of the first driven wheel 442; the second limiting portion 22122 is a planar limiting portion, and the limiting member 24 has a limiting plate. The outer surface of the limiting plate is arc-shaped, adapting to the shape of the inner wall of the lens housing 23, and the inner side of the limiting plate is planar, fitting against the second limiting portion 22122. More specifically, the number of first limiting portions 241 can be the same as the number of second limiting portions 22122, or the number of first limiting portions 241 can be different from the number of second limiting portions 22122. Figure 7 As shown, there can be two first limiting parts 241, and there are also two corresponding second limiting parts 22122.
[0148] Specifically, the first limiting part 241 may also be a limiting groove provided on the connecting part 2212, the groove extending in a horizontal direction, and the second limiting part 22122 may be a limiting rod that cooperates with the limiting groove. This application does not limit the shape of the first limiting part 241 and the second limiting part 22122.
[0149] In some embodiments of this application, such as Figure 6 and Figure 7 As shown, the limiting member 24 has an annular groove 242 on the side away from the focusing lens barrel 221; the outer ring wall of the annular groove 242 has a clearance notch 2411; the first drive gear 441 passes through the bottom wall of the annular groove 242, and the first external tooth portion of the first drive gear 441 is located in the clearance notch 2411; a gear pressure plate 26 is provided on the end face of the second end of the first drive gear 441, the gear pressure plate 26 is fixedly connected to the outer wall of the annular groove 242, and the auxiliary connecting rod 43 passes through the gear pressure plate 26 and is fixedly connected to the first drive gear 441.
[0150] In this embodiment, the annular groove 242 provides space for the first drive gear 441 and the gear plate 26, resulting in a more compact structure and space saving. The first external tooth portion of the first drive gear 441 is located within the clearance notch 2411. The clearance notch 2411 prevents the first drive gear 441 from interfering with the annular groove 242 after rotation, improving reliability during transmission. The auxiliary connecting rod 43 passes through the gear plate 26 and is fixedly connected to the first drive gear 441. The gear plate 26 provides support for the auxiliary connecting rod 43, reducing the probability of breakage of the auxiliary connecting rod 43 near the first drive gear 441.
[0151] In some embodiments of this application, such as Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 As shown, Figure 8A partial cross-sectional view of the observation and aiming device of the second embodiment provided in this application; Figure 9 for Figure 8 An exploded view of the internal structure of the lens housing in the observation and aiming device of the second embodiment shown; Figure 10 for Figure 9 A cross-sectional view of the internal structure of the lens housing shown. Figure 11 for Figure 8 A schematic diagram showing the connection between the transmission mechanism, the focusing handwheel, and the focusing lens barrel in the observation and aiming device of the second embodiment shown; Figure 12 for Figure 11 The diagram shows the connection between the transmission mechanism and the focusing lens barrel. The second end of the auxiliary connecting rod 43 is provided with a partial external thread. The first sub-transmission mechanism 44 includes: a bushing 443; the bushing 443 extends into the focusing lens barrel 221 and is fixedly connected to it, and the inner wall of the bushing 443 is provided with an internal thread; the partial external thread of the auxiliary connecting rod 43 cooperates with the internal thread of the bushing 443 to drive the focusing lens barrel 221 to slide horizontally within the lens housing 23.
[0152] In this embodiment, the auxiliary connecting rod 43 is connected to the main connecting rod 42 in a transmission manner, and the second end of the auxiliary connecting rod 43 is inserted into the threaded hole of the bushing 443. When the focusing handwheel 31 is rotated, the main connecting rod 42 drives the auxiliary connecting rod 43 to rotate. Since the bushing 443 is fixedly connected to the focusing lens barrel 221 by threads, and the first limiting part 241 of the limiting member 24 limits the movement direction of the focusing lens barrel 221, the focusing lens barrel 221 can slide in the horizontal direction, thereby adjusting the distance between the optical lens inside the focusing lens barrel 221 and the camera core, thereby achieving focusing.
[0153] In some embodiments of this application, such as Figure 13 and Figure 14 As shown, Figure 13 Exploded view of the internal structure of the lens housing, the camera module, and the connecting housing; Figure 14 This is an exploded view of the second sub-transmission mechanism in the embodiment of this application; the camera core 21 has a connecting rod clearance groove 211, and the auxiliary connecting rod 43 passes through the connecting rod clearance groove 211 and is connected to the lens assembly 22 in a transmission manner.
[0154] In this embodiment, the connecting rod clearance groove 211 can prevent the auxiliary connecting rod 43 from interfering with the camera core 21 during rotation, thereby improving the stability and reliability of the auxiliary connecting rod 43 during transmission.

[0156] In this embodiment, the first gearbox 451 houses the main connecting rod transmission gear 452, the intermediate transmission gear 453, and the auxiliary connecting rod transmission gear 454. It protects and prevents dust from entering the gears, thus preventing gear transmission jamming and ensuring smoother transmission. The main connecting rod transmission gear 452, the intermediate transmission gear 453, and the auxiliary connecting rod transmission gear 454 are arranged sequentially along a direction perpendicular to the main connecting rod 42. The main connecting rod transmission gear 452 is fixedly connected to the main connecting rod 42, and the auxiliary connecting rod transmission gear 454 is fixedly connected to the auxiliary connecting rod 43. This achieves a staggered arrangement of the main connecting rod 42 and the auxiliary connecting rod 43 in a direction perpendicular to the main connecting rod 42, preventing interference between them during transmission and resulting in a more rational internal structural layout for the observation and aiming equipment.
[0157] Specifically, the first gearbox 451 includes a first gearbox cover 4511 and a second gearbox cover 4512, which can be fixedly connected by snap-fit or threaded connection. The main connecting rod drive gear 452, the intermediate drive gear 453 and the auxiliary connecting rod drive gear 454 are located in the receiving space formed by the first gearbox cover and the second gearbox cover.
[0158] More specifically, the main connecting rod drive gear 452, intermediate drive gear 453, and auxiliary connecting rod drive gear 454 each have a main connecting rod drive gear shaft 4521, an intermediate drive gear shaft 4531, and an auxiliary connecting rod drive gear shaft 4541, respectively. The main connecting rod is fixedly connected to the main connecting rod drive gear shaft 4521 by screws, and the auxiliary connecting rod is fixedly connected to the auxiliary connecting rod drive gear shaft 4541 by screws. The first gearbox cover 4511 has three first mounting shaft holes 45110. The positions of the three first mounting shaft holes 45110 are respectively opposite to the positions of the main connecting rod drive gear shaft 4521, intermediate drive gear shaft 4531, and auxiliary connecting rod drive gear shaft 4541. The main connecting rod drive gear shaft 4521, intermediate drive gear shaft 4531, and auxiliary connecting rod drive gear shaft 4541 are rotatably connected to the three first mounting shaft holes 45110. Similarly, the second gearbox cover 4512 is provided with a second mounting shaft hole 45120 corresponding to the first mounting shaft hole 45110.
[0159] It should be noted that the transmission ratios of the main connecting rod transmission gear 452, the intermediate transmission gear 453, and the auxiliary connecting rod transmission gear 454 can be set according to actual needs, and this application does not limit the transmission ratio.
[0160] In some embodiments of this application, such as Figure 15 , Figure 16 , Figure 17 , Figure 18 and Figure 19 As shown, Figure 15 A partial cross-sectional view of the observation and aiming device of the third embodiment provided in this application; Figure 16 for Figure 15 An exploded view of the internal structure of the lens housing and part of the transmission mechanism in the observation and aiming device of the third embodiment shown. Figure 17 for Figure 16 The image shows a cross-sectional view of the internal structure of the lens housing and part of the transmission mechanism. Figure 18 for Figure 15 A schematic diagram showing the connection between the transmission mechanism, the focusing handwheel, and the focusing lens barrel in the observation and aiming device of the third embodiment shown; Figure 19 for Figure 18 The diagram shows the connection between the transmission mechanism and the focusing lens barrel; the second end of the main connecting rod 42 has a second internal thread; the first sub-transmission mechanism 44 includes: a first connecting plate 445, the first end of the first connecting plate 445 has a second external thread, and the second external thread of the first end engages with the second internal thread of the second end of the main connecting rod 42; the second end of the first connecting plate 445 is fixedly connected to the first end of the auxiliary connecting rod 43; the second end of the auxiliary connecting rod 43 is fixedly connected to the focusing lens barrel 221.
[0161] In this embodiment, rotating the focusing handwheel 31 drives the main connecting rod 42 to rotate. Since the second end of the main connecting rod 42 is threadedly connected to the first end of the first connecting plate 445, and the first connecting plate 445 is fixedly connected to the focusing lens barrel 221 through the auxiliary connecting rod 43, under the limitation of the focusing lens barrel 221 by the limiting member 24, the focusing lens barrel 221 is driven to move in the horizontal direction through the auxiliary connecting rod 43 and the first connecting plate 445 to achieve focusing.
[0162] Specifically, such as Figure 15 , Figure 16 , Figure 17 , Figure 18 and Figure 19 As shown, the second end of the main connecting rod 42 has a threaded bushing 421, and the second internal thread is located on the inner wall of the threaded bushing 421. One end of the threaded bushing 421 is provided with a support frame 420. The main connecting rod 42 passes through the support frame 420 and is threadedly connected to the first connecting plate 445. The support frame 420 is fixedly connected to the connecting housing 30.
[0163] In some embodiments of this application, such as Figure 20 , Figure 21 , Figure 22 , Figure 23 , Figure 24 , Figure 25 , Figure 26 and Figure 27 As shown, Figure 20 A partial cross-sectional view of the observation and aiming device of the fourth embodiment provided in this application; Figure 21 for Figure 20 An exploded view of the focusing handwheel, fixed base, control button knob, and handwheel transmission structure in the observation and aiming device of the fourth embodiment shown; Figure 22 This is a schematic diagram of the arc-shaped guide groove in an embodiment of this application; Figure 23 for Figure 20 An exploded view of the internal structure of the lens housing and part of the transmission mechanism in the observation and aiming device of the fourth embodiment shown. Figure 24 for Figure 22 The image shows a cross-sectional view of the internal structure of the lens housing and part of the transmission mechanism. Figure 25 for Figure 20 A schematic diagram showing the connection between the transmission mechanism, the focusing handwheel, and the focusing lens barrel in the fourth embodiment of the observation and aiming device shown; Figure 26 for Figure 25 The diagram shows the connection between the focusing handwheel and the main connecting rod. Figure 27 for Figure 25The diagram shows the connection between the transmission mechanism and the focusing lens barrel; the fixed base 32 is embedded in the inner side of the top wall of the connecting housing 30; the handwheel transmission structure 41 includes: a transmission slider 413 and a transmission guide pin 414 installed on the top of the transmission slider 413; the focusing handwheel 31 includes: a rotating housing 311 and an annular step 312 located inside the rotating housing 311; the annular step 312 is arranged around the inner wall of the rotating housing 311 and is integrally formed with the rotating housing 311; and an arc-shaped guide groove 3111 is provided below the annular step; the transmission slider 413 is arranged on the side of the fixed base 32 facing the objective lens end 20 and is fixedly connected to the first end of the main connecting rod 42; the transmission guide pin 414 is used to cooperate with the arc-shaped guide groove 3111 so that when the focusing handwheel 31 rotates, the transmission slider 413 drives the main connecting rod 42 to move horizontally in the direction inside and outside the fixed base 32, so as to drive the main connecting rod 42 to move horizontally in the direction towards or away from the focusing handwheel 31.
[0164] In this embodiment, the transmission guide pin 414 has a rod and a head. The rod is fixedly connected to the transmission slider 413, and the head is slidably connected to the arc-shaped guide groove 3111 of the focusing handwheel 31. The fixed base 32 is provided with the transmission slider 413 on the side facing the objective lens end 20, and is slidably connected to the fixed base 32. The transmission slider 413 is also fixedly connected to the main connecting rod 42. Therefore, rotating the focusing handwheel 31 causes the arc-shaped guide groove 3111 of the focusing handwheel 31 to push the transmission guide pin 414 to move horizontally, thereby driving the main connecting rod 42, which is fixedly connected to the transmission guide pin 414, to move horizontally. Since the second end of the main connecting rod 42 is connected to the auxiliary connecting rod 43, and the auxiliary connecting rod 43 is connected to the lens assembly 22, the main connecting rod 42 can drive the auxiliary connecting rod 43 to move horizontally, thereby driving the lens assembly 22 to move horizontally, thus achieving focusing. In this embodiment, the rotational motion of the focusing handwheel 31 is converted into the translational motion of the main connecting rod 42 by the transmission guide pin 414 cooperating with the arc-shaped guide groove 3111 of the focusing handwheel 31. The structure is simple and the manufacturing cost is low, thus saving the manufacturing cost of the observation and aiming equipment.

[0171] In this embodiment, the transmission slider 413 is slidably connected to the second mounting notch 328. The inner side of the second mounting notch 328 can limit the movement of the transmission slider 413, so that when the side wall of the arc-shaped guide groove 3111 of the focusing handwheel 31 pushes the transmission guide pin 414, the transmission slider 413, which is fixedly connected to the transmission guide pin 414, can only move in the horizontal direction.
