Description

Technical Field

[0001] This invention relates to the field of aiming scope technology, specifically to an infrared aiming scope and its focusing structure. Background Technology

[0002] In the field of modern optoelectronic technology, sights play a crucial role in numerous areas. With the rapid development of technology, infrared sights, thanks to their superior functional characteristics, have gradually emerged in the market and become a focus of industry attention. However, while different types of infrared sights have different functional focuses, they all face the problem of a lack of versatility and flexibility in their adjustment mechanisms. Users accustomed to traditional white light sights find it difficult to adapt to the button operation of existing infrared sights when switching to digital sights, resulting in reduced aiming efficiency and a poor user experience. Summary of the Invention

[0003] The purpose of this invention is to provide an infrared sight and its focusing structure to suit the operating habits of users of white light sights.

[0004] To solve the above technical problems, the present invention provides a focusing structure for an infrared sight, including a focusing knob and a focusing screw; the focusing knob is disposed on the outside of the infrared sight body, and a curved groove is provided at the bottom of the focusing knob; one end of the focusing screw is located in the curved groove, and the other end passes through the oval hole of the sight body and is connected to the focusing lens group inside the infrared sight. When focusing, rotating the focusing knob causes the focusing screw to move linearly in the oblong hole, which in turn moves the focusing lens assembly along the optical axis of the infrared sight, thus achieving the focusing function.

[0005] According to the above scheme, the focusing knob includes a focusing wheel and a decorative cover. The curved groove is located at the bottom of the focusing wheel, and the decorative cover is located on the outer end face of the focusing wheel.

[0006] According to the above scheme, a focusing structure sealing ring is provided between the focusing wheel and the lens body.

[0007] The present invention also provides an infrared sight with the focusing structure described above.

[0008] According to the above scheme, the focusing lens assembly includes a focusing lens frame and a bushing; the bushing is fixed to the lens body, the focusing lens frame is slidably connected to the inside of the bushing, and a connecting rod is provided protruding from the focusing lens frame along the optical axis, the connecting rod being connected to the focusing screw.

[0009] According to the above scheme, a focusing lens is installed inside the focusing lens frame, and the focusing lens is fixed inside the focusing lens frame by a focusing lens retaining ring.

[0010] According to the above scheme, the focusing lens frame is connected to a spring retaining ring. One end of the spring retaining ring has an annular protrusion on the outside. A focusing spring is sleeved on the outside of the spring retaining ring, and the focusing spring is located between the annular protrusion and the end face of the bushing.

[0011] According to the above scheme, the battery cover assembly is located on the outer end of the battery compartment of the infrared sight; the battery cover assembly includes a battery holder, a rotating shaft, an adjusting screw, a limiting ring, a battery cover, and a limiting screw. The battery holder is fixed to the lens body, and the inner side of the battery holder is provided with a first locking tooth; The rotating shaft is located inside the battery holder, and a second locking tooth is provided on the outer side of the rotating shaft, which cooperates with the first locking tooth. The battery cover is fixed to the drive shaft; The limiting ring is fixed to the outside of the battery holder; The top of the adjusting screw is connected to the bottom of the rotating shaft through a shaft hole, allowing the adjusting screw to move axially with the rotating shaft but not to rotate relative to it; the bottom of the adjusting screw is threaded to the battery holder. The limit screw is fixed to the bottom of the adjusting screw; When the battery cover assembly is in the unlocked state, lift the battery cover upwards. The battery cover drives the rotating shaft to move upwards. At this time, the second locking tooth disengages from the first locking tooth, and the rotating shaft can rotate inside the battery holder. When the rotating shaft rotates, it drives the adjusting screw to rotate. The adjusting screw moves axially under the action of the thread, which in turn drives the limit screw to move axially. When the limit screw contacts the battery in the battery compartment, the power supply circuit is turned on and the infrared sight is powered on. When the limit screw disengages from the battery, the power supply circuit is turned off and the infrared sight is powered off. When the battery cover is locked, pressing it down causes the rotating shaft to move downwards. At this time, the second locking tooth engages with the first locking tooth, preventing the rotating shaft from rotating inside the battery holder, and the position of the limit screw is locked.

[0012] According to the above scheme, a positioning hole is provided on the side of the rotating shaft, and a positioning spring, a positioning pin, and a positioning ball are provided in the positioning hole; when the battery cover is in the unlocked state, the positioning ball is aligned with the first locking tooth. At this time, when the battery cover is rotated, the positioning ball moves between different teeth of the first locking tooth.

[0013] According to the above scheme, the side of the rotating shaft is provided with an unlocking gear slot and a locking gear slot; the inner side of the limiting ring is provided with a gear hole, and a gear screw, a gear spring, and a gear ball are provided in the gear hole; when the battery cover assembly is in the unlocked state, the gear ball is located in the unlocking gear slot, and when the battery cover is in the locked state, the gear ball is located in the locking gear slot.

[0014] Beneficial effects This invention places the focusing knob on the outside of the scope body, combined with the coordinated design of the curved groove at the bottom of the focusing knob and the focusing screw. Rotating the focusing knob drives the focusing screw to move linearly within the oval hole of the scope body, thereby driving the focusing lens assembly to move precisely along the optical axis of the infrared sight to complete focusing. Its operation method perfectly matches the side-focusing logic of traditional white light sights, allowing users accustomed to traditional white light sights to operate without changing their long-established habits. This avoids the problem of decreased aiming efficiency caused by adapting to new button operations, significantly improving usability and operational comfort. Simultaneously, the direct and stable transmission between the curved groove and the focusing screw accurately converts the knob's rotation into linear displacement of the focusing lens assembly, effectively reducing deviations during focusing and ensuring aiming accuracy. The overall structure achieves focusing functionality solely through the synergistic action of core components such as the focusing knob and focusing screw. The simple and tightly integrated structure not only reduces assembly complexity but also minimizes potential malfunctions, improving the reliability and durability of the focusing structure.

One end of the focusing screw 26 is located in the curved groove, and the other end passes through the oval hole of the sight body and is connected to the focusing lens 23 group inside the infrared sight. When focusing, rotating the focusing knob causes the focusing screw 26 to move linearly in the oblong hole, which in turn causes the focusing lens group 23 to move along the optical axis of the infrared sight, thus achieving the focusing function.

[0019] Furthermore, the focusing knob includes a focusing wheel 18 and a decorative cover 17. A curved groove is provided at the bottom of the focusing wheel 18, and the decorative cover 17 is provided on the outer end face of the focusing wheel 18.

[0020] Furthermore, a focusing structure sealing ring 19 is provided between the focusing wheel 18 and the lens body.

[0022] Furthermore, the focusing lens group 23 includes a focusing lens frame 25 and a bushing 24; the bushing 24 is fixed to the lens body, the focusing lens frame 25 is slidably connected to the inside of the bushing 24, and a connecting rod is provided protruding from the focusing lens frame 25 along the optical axis direction, the connecting rod being connected to the focusing screw 26.

[0023] Specifically, the focusing structure and the focusing lens group 23 work together to realize the focusing function of the product (infrared sight). The bushing 24 in the focusing lens group 23 is connected to the focusing wheel 18 through the focusing screw 26, which moves the focusing position of the product from the lens to the middle position of the sight, improving the user experience and efficiency of users who are accustomed to traditional optical sights.

[0024] Furthermore, a focusing lens 23 is provided inside the focusing lens frame 25, and the focusing lens 23 is fixed inside the focusing lens frame 25 by a focusing lens retaining ring 22.

Battery cover 5 is fixed to the drive shaft; The limiting ring 4 is fixed to the outside of the battery holder 1; The top of the adjusting screw 2 is connected to the bottom of the rotating shaft 3 through a shaft hole, so that the adjusting screw 2 can make axial displacement with the rotating shaft 3, but cannot make relative rotation; the bottom of the adjusting screw 2 is threadedly connected to the battery holder 1. The limit screw 10 is fixed to the bottom of the adjusting screw 2; When the battery cover assembly is in the unlocked state, lift the battery cover 5 upwards. The battery cover 5 drives the rotating shaft 3 to move upwards. At this time, the second locking tooth disengages from the first locking tooth, and the rotating shaft 3 can rotate within the battery holder 1. When the rotating shaft 3 rotates, it drives the adjusting screw 2 to rotate. The adjusting screw 2 moves axially under the action of the thread, which in turn drives the limiting screw 10 to move axially. When the limiting screw 10 contacts the battery in the battery compartment, the power supply circuit is connected and the infrared sight is turned on. When the limiting screw 10 disengages from the battery, the power supply circuit is disconnected and the infrared sight is turned off. When the battery cover 5 is locked, press the battery cover 5 down. The battery cover 5 drives the rotating shaft 3 to move downward. At this time, the second locking tooth and the first locking tooth engage, and the rotating shaft 3 cannot rotate inside the battery holder 1. The position of the limit screw 10 is locked.

[0027] Specifically, an open retaining ring 16 is provided at the bottom of the adjusting screw 2 to limit the axial position of the adjusting screw 2. The battery cover 5 is connected to the drive shaft by screws 15. The limiting ring 4 is used to limit the axial position of the rotating shaft 3 to prevent the rotating shaft 3 from dislodging when the battery cover 5 is unlocked.

At this time, when the battery cover 5 is rotated, the positioning ball 13 moves between different teeth of the first locking tooth (to provide an adjustment feel when rotating).

[0029] Specifically, in this embodiment, a pair of positioning springs 8, positioning pins, and positioning balls 13 are provided.

[0030] Furthermore, the rotating shaft 3 has an unlocking slot and a locking slot on its side; the limit ring 4 has a gear hole on its inner side, and a gear screw 12, a gear spring 9, and a gear ball 14 are installed in the gear hole; when the battery cover is in the unlocked state, the gear ball 14 is located in the unlocking slot, and when the battery cover 5 is in the locked state, the gear ball 14 is located in the locking slot (to provide a gear feel when locking and unlocking).

[0031] Specifically, in this embodiment, both the positioning ball 13 and the stop ball 14 are steel balls.

[0032] This invention simulates the side focusing and adjustment screw 2 of a traditional white light scope by setting up a focusing lens group 23, a focusing handwheel group, and a battery cover group to capture the user's rotation operation and realize the focusing and power-on / off functions.
