DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] Example 1

[0027] In this embodiment, if Figure 1-Figure 6 As shown, the night vision device with a lens that can be quickly detached includes a main housing 101, wherein the main housing 101 is provided with electronic components for adjusting parameters, a lens 102 is detachably connected to one side of the main housing 101, so as to facilitate quick replacement of the lens 102, and a visual portion 103 is connected to the other side of the main housing 101, so as to facilitate a user to observe the lens through the visual portion 103, and further includes a detachment mechanism 200 and a protection mechanism 300, wherein the detachment mechanism 200 is arranged between the lens 102 and the main housing 101, so as to install the lens 102 on the main housing 101, and the protection mechanism 300 is arranged on the outer side of the lens 102, so as to prevent the lens 102 from being damaged. Before the night vision device with a lens that can be quickly detached is used, first check whether the night vision device can be used normally, and then install and fix the lens 102 through the detachment mechanism 200, so as to facilitate quick detachment of the lens 102, so that the night vision device enters a state to be used;

[0028] Among them Figure 2-Figure 5As shown, the disassembly mechanism 200 includes a mounting plate 201 disposed on one side of the lens 102, which is installed between the mounting plate 201 and the main housing 101 to avoid affecting the lens or other components inside the lens 102. The mounting plate 201 is symmetrically provided with slide grooves 202 inside to increase structural stability. The slide grooves 202 can also be provided on only one side of the mounting plate 201 to facilitate quick disassembly of the lens 102. The slide groove 202 is slidably connected to a slider 203 inside, and a support rod 204 is fixedly connected to one side of the slider 203. When the slider 203 moves, it can drive the support rod 204 to move. One end of the support rod 204 extends to the outside of the mounting plate 201 and is connected to a fixing component. When the card plate 208 and the card slot 211 are engaged, the position of the support rod 204 is fixed by the fixing assembly, so that the slider 203 cannot be displaced. The slider 203 is connected to the inner wall of the slide slot 202 by the spring 205. The spring 205 enables the slider 203 to have the ability to self-restore to its original position. After the lens 102 is installed, the spring 205 generates a squeezing force on the slider 203, thereby improving the engagement effect of the card plate 208 and the card slot 211. The spring 205 is arranged on the side of the slide slot 202 close to the support rod 204, and the side of the slider 203 away from the mounting plate 201 is provided with a card assembly, which is convenient for quick disassembly and installation of the lens 102, and convenient for cleaning and replacement.

[0029] Among them Figure 2 and Figure 6 As shown, the protection mechanism 300 includes a fixing ring 301 threadedly connected to the lens 102, which is convenient for disassembly of the fixing ring 301. The fixing ring 301 is made of a relatively hard material and plays a protective role. A rubber ring 302 is fixedly installed on the outer side of the fixing ring 301. A transparent protection sheet 303 is installed inside the fixing ring 301. The transparent protection sheet 303 is arranged on a side close to the lens 102 to prevent the lens from being damaged. A dustproof net 304 is arranged on a side of the transparent protection sheet 303 away from the lens 102 to prevent dust from adhering to the surface of the lens 102 when the lens 102 is idle, thereby affecting the use.

[0030] Among them Figure 3 and Figure 5 As shown, the fixing assembly includes a rotating plate 206 rotatably connected to the mounting plate 201, and an arc groove 207 is provided on the lower surface of the rotating plate 206. The arc groove 207 has a limiting effect on the support rod 204 to prevent the user from accidentally touching the support rod 204 and causing the lens 102 to fall off. The rotating plate 206 is fixedly connected to the mounting plate 201 through a latch, and one end of the latch is connected to the mounting plate 201 through a tension spring to prevent the latch from being lost;

[0031] Among them Figure 3 and Figure 4As shown, the card assembly includes a card plate 208 fixedly connected to the slider 203, and the main housing 101 is symmetrically provided with mounting grooves 209, and a card block 210 is provided inside the mounting groove 209. The number and size of the card plates 208 are adapted to the card grooves 211. The card plates 208 cooperate with the card grooves 211 to achieve sliding limit of the lens 102. The middle part of the upper surface of the card block 210 is provided with a card groove 211, and the card groove 211 is adapted to the size of the card plate 208. The card plate 208 is carded into the card groove 211, thereby fixing the card plate 208, and then fixing the lens 102;

[0032] Among them Figure 1 As shown, anti-slip grooves 104 are provided on the surface of the main housing 101 to increase the contact area between the user and the main housing 101, improve the friction effect, and prevent the user from slipping when holding the night vision device;

[0033] Example 2

[0034] The difference from Example 1 is that Figure 2 and Figure 3 As shown, a non-slip pad is provided on one side of the mounting plate 201 close to the main housing 101, and an opening adapted to the clamping plate 208 is provided on the surface of the non-slip pad. The non-slip pad allows a certain elastic space to exist between the mounting plate 201 and the main housing 101, and the non-slip pad can increase the friction force, thereby increasing the safety and stability of the main housing 101.

[0035] Among them Figure 2 and Figure 3 As shown, a guide column 212 is fixedly installed inside the slide groove 202, and the slider 203 is slidably connected to the guide column 212, which guides the slider 203 to prevent the slider 203 from deviating during use and then getting stuck.

[0036] When in use, the user first aligns the lens 102 with the main shell 101, so that the card plates 208 on both sides can slide with the card block 210 with the cooperation of the trapezoidal edges. Due to the connection between the slider 203 and the card plate 208, the slider 203 slides inside the slide groove 202. At this time, the spring 205 is compressed to the maximum extent. One end of the card plate 208 slides with the card block 210, and then can be smoothly connected to the inside of the card groove 211. At this time, with the cooperation of the spring 205, the slider 203 recovers a certain distance, and the spring 205 squeezes the slider 203, and then the support rod 204 is limited by the fixing assembly to increase the structural stability. When the lens 102 needs to be disassembled, just pull out the pin, move the rotating plate 206 to one side, and then pull out the support rod 204.

[0037] The above is only a specific implementation of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
