[0039] Embodiment 2

[0040] Reference Figures 2-11 As a second embodiment of the utility model, the embodiment is based on the previous embodiment.

[0041] The connecting block 31 is provided with a second connecting groove 31-1 on one side, which provides support for the portable installation of the lens barrel mechanism 3; the shape and size of the second connecting groove 31-1 are adapted to the matching components on the sliding block 22; through the sliding cooperation of the two, the stable connection of the connecting block 31 and the sliding block 22 is ensured, and at the same time, the lens barrel mechanism 3 is allowed to smoothly slide and adjust under the driving of the sliding block 22, thereby providing a structural basis for realizing accurate pupil distance adjustment.

[0042] The sliding block 25 is arranged on one side of the sliding block 22 and cooperates with the second connecting groove 31-1; the sliding block 25 arranged on one side of the sliding block 22 cooperates with the second connecting groove 31-1 of the connecting block 31, thereby constituting a sliding connection structure between the lens barrel mechanism 3 and the connecting mechanism 2; the outer contour of the sliding block 25 is closely matched with the second connecting groove 31-1, so that the sliding movement of the sliding block 25 in the second connecting groove 31-1 is ensured, and at the same time, the movement of the connecting block 31 in the non-adjustment direction is limited, thereby ensuring that the lens barrel 32 can stably move along the predetermined direction during the adjustment of the pupil distance, and the accuracy and stability of the adjustment are improved.

[0043] Rotary grooves 11-2 are arranged on both sides of the connecting groove 11-1, and the rotary block 21 is fixedly connected with a circular block 21-1 on both sides and matched with the rotary grooves 11-2. This design enables the rotary block 21 to rotate flexibly in the rotary grooves 11-2 with the circular block 21-1 as the shaft. The rotation of the rotary block 21 can adjust the angle relationship between the connecting mechanism 2 and the supporting mechanism 1, thereby providing more adjustment dimensions for the pupil distance adjustment of the lens barrel mechanism 3 to meet the needs of different users in different use scenarios.

[0044] The sliding block 22 is provided with a sliding rail block 22-1 on one side, and the rotary block 21 is provided with a sliding rail groove 21-2 on one side and matched with the sliding rail block 22-1. The sliding rail block 22-1 on one side of the sliding block 22 is matched with the sliding rail groove 21-2 on one side of the rotary block 21 to form a sliding guide structure of the sliding block 22 on the rotary block 21. This matching mode can effectively limit the deviation and shaking of the sliding block 22 during sliding to ensure the sliding block 22 to slide stably along the predetermined straight track, thereby realizing the accurate displacement of the lens barrel mechanism 3 and ensuring the accuracy of the pupil distance adjustment.

[0045] The rotating member 24 includes a rotating round handle 24-1, which provides an operation part for the user to facilitate manual rotation. The rotating round handle 24-1 is fixedly connected with a latch 24-2 on one side, which plays a role in connection and transmission to transfer the rotating action of the rotating round handle 24-1 to the extrusion block 23. The latch 24-2 is provided with a threaded ring 24-3, which is matched with the threaded hole 21-3 on the rotary block 21. When the rotating round handle 24-1 is rotated, the threaded ring 24-3 is screwed in or out of the threaded hole 21-3 to drive the latch 24-2 to move and thereby push the extrusion block 23 to apply different degrees of extrusion force to the sliding block 22 to realize the adjustment of the sliding resistance of the sliding block 22.

[0046] A threaded hole 21-3 matched with the connecting hole 23-1 is arranged on one side of the rotary block 21, and the threaded hole 21-3 is matched with the threaded ring 24-3. The two are connected by threads to realize the fastening connection of the rotating member 24 and the rotary block 21. When the rotating round handle 24-1 is rotated, the threaded ring 24-3 is screwed in or out of the threaded hole 21-3 to accurately control the displacement of the latch 24-2 and thereby accurately adjust the extrusion force of the extrusion block 23 to the sliding block 22 to support the realization of the stepless locking mechanism.

[0047] The anti-dropping piece 26 is arranged on both sides of the sliding block 22, including a limiting hole 26-1 arranged on one side of the sliding block 22, and a first bolt 26-2 rotatably arranged in the limiting hole 26-1. During installation and use, the first bolt 26-2 is tightened, so that the end of the first bolt 26-2 is in contact with the rotating block 21 or other fixed components, thereby limiting the sliding range of the sliding block 22 in the sliding groove 21-2, preventing the sliding block 22 from being separated from the rotating block 21 during adjustment, and effectively improving the safety and reliability of the sliding rail structure.

[0048] The gear 24-4 is arranged on the outer wall of the rotating round handle 24-1, which increases the friction between the rotating round handle 24-1 and the hands of the user. When adjusting the interpupillary distance, the user holds and rotates the rotating round handle 24-1, the gear 24-4 can provide better holding feeling and operation feedback, so that the rotating operation is more stable and accurate, the adjustment error caused by hand slipping is avoided, and the operation convenience is improved.

[0049] The second threaded hole 22-2 is arranged on one side of the sliding block 22 and penetrates the sliding block 25, and the second bolt 22-3 is rotatably arranged in the second threaded hole 22-2. When the sliding block 25 slides into the second connecting groove 31-1, the second bolt 22-3 is rotated and tightened to eliminate the sliding gap between the sliding block 22 and the connecting block 31, thereby enhancing the connection stability.

[0050] In use, first, the entire support mechanism 1 and the lens barrel mechanism 3 are connected through the connecting mechanism 2, then the interpupillary distance is adjusted by moving the rotating block 21 to slide in the sliding block 22, and after the interpupillary distance is adjusted to the appropriate interpupillary distance of the user, the rotating round handle 24-1 is rotated to adjust the extrusion force of the extrusion block 23 on the sliding block 22 by cooperation of the threaded ring 24-3 on the rotating member 24 and the threaded hole 21-3 on the rotating block 21, thereby locking the sliding of the rotating block 21 on the sliding block 22, and facilitating operation.

[0051] In summary, through cooperation of the connecting mechanism 2, the position can be changed by moving the sliding rail, and when the lens barrel 32 reaches the required position of the interpupillary distance, the sliding rail is locked and positioned by the locking mechanism, thereby completing the interpupillary distance adjustment purpose. Compared with the prior art, the operation is convenient, and the structure is stable.

[0052] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, not to limit it. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, which should be covered in the scope of the claims of the present application.
