The front housing 1 is also provided with a pupil distance adjustment structure 3, and the two optical lenses 11 are respectively connected to the pupil distance adjustment structure 3.

[0028] In one embodiment, the front housing 1 and rear housing 2 are secured together by screws, with a decorative strip 4 positioned at the junction of the two housings. The front side of the front housing 1 also includes a strip groove 12 and a camera removable groove 13, with the optical lens 11 mounted outside the camera removable groove 13. A power switch 21, a diode 22, and a DC connector 23 are also positioned at the top of the rear housing 2.

[0029] In one embodiment, the interpupillary distance adjustment mechanism 3 includes a handwheel 31, a screw 32, a linear track 34, and a tensioning assembly slidably disposed on the linear track 34. The handwheel 31 is disposed at the upper end of the front housing 1, and the screw 32, linear track 34, and tensioning assembly are disposed within the housing. The screw 32 passes through the front housing 1 and is fixedly connected to the handwheel 31. The screw 32 is also threadedly connected to a first rotating shaft seat 33, which is connected to the tensioning assembly via screws. Rotation of the screw 32 drives the first rotating shaft seat 33 to move up and down within the front housing 1.

[0030] In one embodiment, the tension assembly includes an elastic plate 350, a rotating shaft 352, and a fixed camera moving assembly 353 slidably connected to the elastic plate 350. A slider 351 is mounted below the elastic plate 350 and slidably connected to the linear track 34. The rotating shaft 352 is slidably connected to the fixed camera moving assembly 353 via a second rotating shaft seat 354. The ends of the rotating shaft 352 are fixed to the front housing 1 via fixed shaft seats 355. In one embodiment, two rotating shafts 352 are provided, one at the upper and lower ends of the fixed camera moving assembly 353.

[0031] In one embodiment, the elastic plate 350 is recessed with two symmetrical connecting parts 3511, and both connecting parts 3511 are provided with an oblique groove 3512, and the oblique grooves 3512 on the two connecting parts 3511 are symmetrically distributed along the extension direction of the screw rod 32; the fixed camera moving component 353 is provided with a connecting column at one end close to the connecting part 3511, and the connecting column is slidably set in the oblique groove 3512; the first rotating shaft seat 33 moves up and down to drive the elastic plate 350 to move up and down in the front shell body 1, and the up and down movement of the elastic plate 350 drives the connecting column to slide in the oblique groove 3512, thereby driving the fixed camera moving component 353 to move left and right in the front shell body 1, thereby adjusting the pupil distance between the two lenses.

[0032] In one embodiment, the fixed camera moving assembly 353 is composed of two camera moving plates 3531 and a camera fixing plate 3532 arranged on the camera moving plate 3531, the connecting column is arranged at one end of the camera moving plate 3531 close to the connecting part 3511, and the two camera moving plates 3531 are provided with an annular positioning block 3534 on the side facing the front shell 1. A visible moving block 3535 is provided on any camera moving plate 3531, and the two camera moving plates 3531 are symmetrically arranged in the front shell 1 along the extension direction of the screw rod 32.

[0033] Specifically, the visual moving block 3535 is slidably disposed in the strip groove 12 , and the moving direction of the camera can be determined according to the left and right sliding position of the visual moving block 3535 in the strip groove 12 .

[0034] Specifically, the camera moving groove 13 is elliptical, and the annular positioning block 3534 is slidably arranged in the camera moving groove 13. The annular positioning block 3534 slides left and right in the elliptical camera moving groove 13. The elliptical camera moving groove 13 limits the sliding direction and sliding position of the annular positioning block 3534, so that the pupil distance between the lenses can be adjusted within a certain range to prevent excessive adjustment.

[0035] The utility model has a screw rod passing through the front housing and connected and fixed with a hand wheel. The screw rod is also threadedly connected to a first rotating shaft seat. The first rotating shaft seat is connected to the elastic assembly through a screw. The screw rod is rotated to drive the first rotating shaft seat to move up and down in the front housing. The up and down movement of the first rotating shaft seat drives the elastic plate to move up and down in the front housing. The up and down movement of the elastic plate drives the connecting column to slide in the oblique groove, thereby driving the fixed camera moving assembly to move left and right in the front housing, thereby adjusting the pupil distance between the two lenses and realizing the measurement of the two display screens, which is simple and convenient.

[0036] The above merely represents the preferred technical solution of the present invention. While the description is relatively specific and detailed, it should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the concept of the present invention, and the present invention is intended to encompass such modifications and variations.
