Description

Technical Field

[0001] This utility model relates to the field of low-light night vision technology, specifically a multifunctional low-light night vision device. Background Technology

[0002] Low-light night vision devices are night observation tools with an image intensifier as their core component. They utilize the light reflected from a target under dim lighting conditions, which is then amplified by the image intensifier onto a fluorescent screen to create a visible image perceptible to the human eye, allowing for target observation and aiming. Currently, commercially available low-light night vision devices are primarily single-lens handheld models, requiring handheld use or use with a ground-mounted support. For police or outdoor applications, both handheld and ground-mounted use significantly limit their application scenarios and hinder the user's ability to perform other operations, greatly reducing the ease of use of the night vision device.

When the adjusting device is rotated to the horizontal direction, the support block abuts against the hinge seat.

[0009] Furthermore, the support shaft is fixedly connected to a bearing plate perpendicular to the support block, and an adjustment device is fixedly connected to the end of the bearing plate away from the support shaft.

[0010] Furthermore, the adjustment device includes a slide groove, which is vertically opened on the support plate. A connecting rod is slidably arranged in the slide groove.

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figure 1-2 This utility model provides a multifunctional low-light night vision device, including a quick-release base 1 mounted on a helmet. The quick-release base 1 is movably connected to a quick-release connector 2. A hinge base 3 is fixedly connected to the end of the quick-release connector 2 away from the quick-release base 1. An adjustment device is hinged to the hinge base 3. A low-light night vision device 4 is fixedly connected to the bottom of one end of the adjustment device and the hinge base 3. A threaded connector is provided between the low-light night vision device 4 and the adjustment device. Generally speaking, most existing night vision device support frames and handheld frames are connected to the low-light night vision device by threads. Retaining the threaded connector can realize the use in multiple scenarios and improve the convenience of use.

[0019] As an implementable example, the quick-release base has two limiting grooves 5, each of which is vertically arranged. Each limiting groove 5 has a support part 7 at its bottom. The quick-release connector 3 is provided with multiple limiting sliders 8, each of which is slidably connected to each limiting groove 5. The bottom of each limiting slider 8 abuts against the support part 7. The support part 7 and the limiting groove 5 form a blind groove, so that the limiting slider 8 can not move downwards after moving to the position of the support part 7, thus completing the installation.

[0020] As an optional embodiment, each of the limiting grooves 5 and each of the limiting sliders 8 is provided with a communicating limiting through hole 6. A limiting pin 9 passes through the limiting through hole 6. The limiting pin 9 passes through each of the limiting grooves 5 and each of the limiting sliders 8. By passing through each limiting through hole 6 and limiting groove 5, the quick-release connector 2 is prevented from disengaging from the quick-release seat 1 due to excessive bumps under extreme working conditions, and the relative displacement of each limiting through hole 6 and each limiting groove 5 is prevented.

[0021] As an optional embodiment, the limiting groove 5 is a "T"-shaped limiting groove, the limiting slider 8 matches the limiting groove 5, the limiting slider 8 moves into the limiting slide plate near the quick-release seat 1, the quick-release connector 2 is connected to the limiting slide plate by a connecting plate, the connecting plate is set perpendicular to the limiting slide plate to form a "T"-shaped slide plate, to avoid relative displacement of each limiting through hole 6 and the limiting groove 5, and to prevent the quick-release connector 2 from disengaging from the quick-release seat 1 due to a large amount of bumps under extreme working conditions.

[0022] As an example of implementation, the hinge seat 3 is hinged to a support shaft 10, and a support block 11 is integrally connected to the support shaft 10 along the tangent and perpendicularly downward on the side of the support shaft 10 near the hinge seat 3. The support shaft 10 and the hinge seat 3 are preferably hinges that can be suspended at multiple angles, which improves the stability of the low-light night vision device 4 when it is retracted upward. At the same time, when the adjustment device is rotated to the horizontal direction, the support block 11 abuts against the hinge seat 3, thus completing the horizontal support of the adjustment device and the low-light night vision device 4.

[0023] As an optional embodiment, the support shaft 10 is fixedly connected to a bearing plate 12 perpendicular to the support block 11, and an adjustment device is fixedly connected to one end of the bearing plate 12 away from the support shaft 10.

[0024] As an optional embodiment, the adjustment device includes a vertically downward-facing groove 13 on the support plate 12, a connecting rod 14 slidably disposed within the groove 13, a sliding sleeve 15 fitted onto the support plate 12, the sliding sleeve 15 being slidably connected to the support plate 12, the connecting rod 14 passing through the center of the sliding sleeve 15, the connecting rod 14 being fixedly connected to the sliding sleeve 15, and the bottom of the connecting rod 14 being fixedly connected to the low-light night vision device 4. The sliding sleeve 15 restricts the connecting rod to move only forward and backward, preventing rotation. Through the cooperation of the connecting rod 14 and the sliding sleeve 15, the tilting of the low-light night vision device 4 due to improper operation when adjusting the distance between the low-light night vision device 4 and the eye is prevented. A fastening bolt 17 passes through the side of the sliding sleeve 15 and abuts against the side of the support plate 12, restricting the relative movement between the sliding sleeve 15 and the support plate 12.

[0025] As an optional embodiment, the bottom of the connecting rod 14 is provided with an external thread, and the low-light night vision device 4 is fixedly connected to a threaded tube 16, which is connected to the connecting rod 14 by a thread.
