[0024] The following will further illustrate the detailed embodiment of the present utility model with reference to the drawings. The same components are denoted by the same reference numerals.

[0025] It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.

[0026] In order to make the content of the present utility model easier to be clearly understood, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model.

[0027] Such as Figure 1 and Figure 2As shown in the figure, a portable low-light night vision device includes a support plate 1. At both ends of the bottom of the support plate 1, there are two groups of distance adjustment structures 2. The distance adjustment structures 2 can adjust the interpupillary distance to meet the needs of different users. At the bottom of the two groups of distance adjustment structures 2, there is a night vision device main body 3. On the opposite sides of the two night vision device main bodies 3, there is a strap 4 fixed. Through the strap 4, a head-mounted night vision device can be realized, and it can also be hung around the neck when not in use. On the opposite sides of the strap 4, there is a placement block 5. Inside the placement block 5, there is an installation groove 6. Inside the installation groove 6, there is an adjustment structure 7. The adjustment structure 7 can adjust the tightness of the strap 4. On the top of the support plate 1, there is a connection port 8. The connection port 8 can meet other usage scenarios. For example, through the connection port 8, the night vision device can be connected to a helmet.

[0028] As Figure 1 and Figure 3 shown in the figure, the distance adjustment structure 2 includes a first fixing block 201. The first fixing block 201 is fixedly connected to both ends of the bottom of the support plate 1. Inside the first fixing block 201, there is an empty groove 202. Inside the empty groove 202, there is a threaded rod 203 rotatably connected. One end of the threaded rod 203 extends out of the empty groove 202 and is fixedly connected to a first rotary handle 204. Outside the threaded rod 203, there is a second fixing block 205 sleeved. The bottom of the second fixing block 205 is fixedly connected to the night vision device main body 3. By driving the threaded rod 203 with the first rotary handle 204, when the threaded rod 203 rotates, it drives the second fixing block 205 to move. The second fixing block 205 drives the two night vision device main bodies 3 to move left and right, realizing the adjustment of the interpupillary distance between different users.

[0029] As Figures 4 to 5 shown in the figure, the adjustment structure 7 includes a bidirectional threaded rod 701. One end of the bidirectional threaded rod 701 extends out of the inner wall of the installation groove 6 and is fixedly connected to a second rotary handle 702. The other end of the bidirectional threaded rod 701 away from the second rotary handle 702 is rotatably connected to the inner wall of the installation groove 6. At both ends of the outside of the bidirectional threaded rod 701, there are moving blocks 703 threadedly connected. At the bottom of the installation groove 6, there is a sliding groove 704. The bottoms of the two moving blocks 703 are slidably connected to the sliding groove 704. The top of the moving block 703 is fixedly connected to a fixing seat 705. On both sides of the placement block 5, there are through holes 706 adapted to the fixing seat 705. On the opposite sides of the two fixing seats 705, there are grooves 707. On the opposite sides of the strap 4, there is a connection buckle 9 fixedly connected. The connection buckle 9 is snap-fitted into the groove 707. The connection buckle 9 is made of an elastic material. After pinching the connection buckle 9 by hand, the connection buckle 9 is made to approach each other and can be snap-fitted into the groove 707. After putting the connection buckle 9 into the groove 707, the connection buckle 9 can be released, and the connection buckle 9 will spring open and can be fixed in the groove 707. By rotating the bidirectional threaded rod 701 with the second rotary handle 702, since the threads on the surface of the bidirectional threaded rod 701 are symmetrical, when rotating, it will drive the moving blocks 703 on both sides to move in opposite or approaching directions, thereby adjusting the tightness of the strap 4.

[0030] As shown Figure 2 in the figure, the two night vision device main bodies 3 include a hand-held base 301 which is fixedly connected to the opposite sides of the night vision device main bodies 3. The hand-held base 301 facilitates the user to hold by hand, avoiding slipping. One end of the night vision device main body 3 is sleeved with an eyepiece protection cover 302. A first connecting rope 303 is fixedly connected between the eyepiece protection cover 302 and the night vision device main body 3. The end of the night vision device main body 3 away from the eyepiece protection cover 302 is sleeved with an objective lens protection cover 304. A second connecting rope 305 is fixedly connected between the objective lens protection cover 304 and the night vision device main body 3. The eyepiece protection cover 302 and the objective lens protection cover 304 can shield the night vision device main body when not in use, avoiding scratches. The first connecting rope 303 can fix the eyepiece protection cover 302 during use, avoiding loss.

[0031] When the present utility model is specifically implemented, as Figures 1 to 5 shown in the figure, when in use, the night vision device main body 3 is worn on the head through a strap 4. Then, after the connecting buckle 9 is snapped into the groove 707, the bidirectional threaded rod 701 is rotated by turning the second handle 702. Since the threads on the surface of the bidirectional threaded rod 701 are symmetrical, when rotated, it will drive the moving blocks 703 on both sides to move towards the opposite or adjacent sides, and the tightness of the strap 4 can be adjusted according to the head sizes of different users. When the interpupillary distance needs to be adjusted, the threaded rod 203 is driven by turning the first handle 204. When the threaded rod 203 rotates, it drives the second fixing block 205 to move, and the second fixing block 205 drives the two night vision device main bodies 3 to move left and right, realizing the adjustment of the interpupillary distance between different users. The arc-shaped pad 401 provided between the straps 4 can prevent the placing block 5 from directly contacting the user, ensuring the comfort of the user while ensuring the tightness of the adjustment.
