Description

Night vision device with detachable video module structure Technical Field The scheme relates to the field of head Dai Weiguang night vision devices, in particular to a night vision device with a detachable video recording module structure. Background The design of the prior eye lens of the head-mounted low-light night vision device is usually only common eye lens, the eye lens is used for observation, no video recording function exists, or the functions of the whole system are concentrated around the eye lens, and the miniature camera module part is not detachable, so that the whole module is bigger. In modern society, in order to expand the perception range of people, the head-mounted equipment is not a mere night vision device, but generally a helmet, a voice communication system and the like are integrated, and if the module is bigger, the installation is difficult or interference with other complete machines exists during the installation. Disclosure of utility model The utility model aims to provide a detachable video module structure for a head-mounted night vision device. The specific technical scheme for solving the technical problems is as follows: the night vision device with the detachable video module structure comprises a lens barrel, wherein the lens barrel comprises an inner barrel, a middle barrel, a shell and a focusing ring, the shell is detachably connected with the night vision device through threads, the middle barrel is fixedly connected with the shell through screws, a waist-shaped hole is formed in the middle barrel, the inner barrel is slidably arranged in the middle barrel, a pin is arranged at the position where the inner barrel is matched with the waist-shaped hole, the pin is arranged in the waist-shaped hole, an annular limiting groove is formed in one end, close to an observed object, of the inner barrel, a sliding ring is arranged in the limiting groove, and the focusing ring is fixed on the sliding ring through screws; the inner barrel is internally and fixedly provided with a lens group, the inner barrel is connected with the focusing ring through threads, and the focusing ring is used for driving the inner barrel to axially move through rotation; The inner barrel is also provided with a video module interface, the video module interface is used for hermetically receiving the miniature camera module, and the lens group is used for transmitting part of collected light rays into the miniature camera module. Compared with the prior art, the scheme has the following beneficial effects: Compact structure, reasonable in design, miniature camera module realizes the gas tightness through video recording module interface and night-time vision device and is connected, has not only guaranteed the steady operation of miniature camera module under adverse circumstances, still is convenient for the user according to actual demand quick replacement or upgrade miniature camera module, avoids forming the interference with other subassemblies, has improved night-time vision device's suitability and flexibility. Meanwhile, due to the design of the focusing ring, a user can adjust the focal length through simple rotation operation, the operation is simple, convenient and quick, and the user experience is improved. In addition, each part in this structure connects firmly, has guaranteed night-time vision device's overall stability and durability. Further, a sealing protruding ring is arranged at the interface of the miniature camera module and the eye lens barrel, a sealing groove is arranged at the interface of the miniature camera module, and a flexible sealing ring is arranged in the sealing groove. The cooperation design of this seal protruding ring and seal groove has ensured the gas tightness of miniature camera module and eye-tube junction, has effectively prevented impurity such as outside moisture, dust from getting into inside the night-time vision device, has further ensured the steady operation of miniature camera module and the inside subassembly of night-time vision device. The use of the flexible sealing ring not only enhances the sealing effect, but also can adapt to the change of environmental conditions such as different temperatures, humidity and the like due to the good elasticity and wear resistance of the flexible sealing ring, and prolongs the service life of the sealing structure. The design details reflect the high importance of the utility model on the durability and applicability of the product again, and provide more reliable and efficient night vision observation experience for users. Further, a locating pin is arranged at the bottom of the miniature camera module, and a locating hole is correspondingly arranged on the eye lens barrel. The matching design of the locating pin and the locating hole ensures that the miniature camera module can be quickly and accurately located during installation, thereby avoiding the problem of offset or looseness of the video module
