In some embodiments, the second return spring 42 may be located between two third restraint rods 52.
Therefore, with such a design, the second barrel 300 can be horizontally slidably connected to the third limiting rod 52.
In one embodiment, the interpupillary distance adjusting apparatus 100 may further include a cover plate 60.
Specifically, the cover plate 60 may include a first connection portion 61, a second connection portion 62, and a shielding portion 63. The shielding portion 63 is fixedly connected between the first connecting portion 61 and the second connecting portion 62, and both the first connecting portion 61 and the second connecting portion 62 are fixedly connected to the top plate 11.
For example, the first connecting portion 61 may be provided with a through hole (not shown), and the second connecting portion 62 may be provided with a through hole (not shown). The top plate 11 may be provided with two fastening holes (not shown), wherein the two fastening holes may be respectively abutted with the through holes of the first connection portion 61 and the second connection portion 62.
Therefore, the two fasteners respectively pass through the through holes of the first connecting portion 61 and the through holes of the second connecting portion 62 and are respectively locked in the two fastening holes on the top plate 11. With this design, the cover plate 60 can be fixedly attached to the top plate 11.
In some embodiments, the shielding portion 63 may be located above the first connecting member 22 and may press against the first connecting member 22.
It can be understood that, when the first connecting part 22 is rotated, the first connecting part 22 can drive the second connecting part 23 to move up and down along the vertical direction of the first limiting rod 21, so that the second connecting part 23 can press the third end of the elastic element 30, and the purpose of adjusting the distance between the first lens barrel 200 and the second lens barrel 300 is further achieved.
For example, as shown in fig. 2, the elastic element 30 is in a convex shape in an initial state, when the first connecting element 22 starts to rotate in a first direction (e.g., clockwise), the second connecting element 23 may move downward along the first limiting rod 21, at this time, the third end of the elastic element 30 moves downward, and both the first end and the second end of the elastic element move outward, the first end of the elastic element 30 drives the first barrel 200 to move in a direction close to the first side plate 13, and the second end of the elastic element 30 drives the second barrel 300 to move in a direction close to the second side plate 14, that is, the elastic element 30 may drive the first barrel 200 and the second barrel 300 to move away from each other and correspondingly compress the first return spring 40 and the second return spring 42.
As shown in fig. 3, when the first connecting element 22 starts to rotate in a second direction (e.g., counterclockwise), the second connecting element 23 can move upward along the first limiting rod 21, at this time, the third end of the elastic element 30 moves upward, and both the first end and the second end of the elastic element 30 move inward, the first end of the elastic element 30 drives the first barrel 200 to move in a direction away from the first side plate 13, and the second end of the elastic element 30 drives the second barrel 300 to move in a direction away from the second side plate 14, that is, under the elastic force of the first return spring 40, the second return spring 42, and the elastic element 30, the first barrel 200 and the second barrel 300 can be driven to approach each other.
Thus, the first barrel 200 and the second barrel 300 can be moved away from each other by rotating the first link clockwise, and the first barrel 200 and the second barrel 300 can be moved closer to each other by rotating the first link clockwise. With such a design, the distance between the first barrel 200 and the second barrel 300 can be very conveniently adjusted.
Referring to fig. 4, fig. 4 is a schematic structural diagram of a second embodiment of a pupil distance adjusting device 100 according to the present application.
The difference from the embodiment of the interpupillary distance adjusting apparatus 100 shown in fig. 2 is that:
as shown in fig. 4, the elastic member 30 in the present embodiment has a concave shape, and the elastic member 30 shown in fig. 2 has a convex shape.

As shown in fig. 4, the elastic element 30 is concave in an initial state, when the first connecting element 22 starts to rotate in a first direction (e.g., clockwise), the second connecting element 23 may move downward along the first limiting rod 21, at this time, the third end of the elastic element 30 moves downward, the first end and the second end of the elastic element both move outward, the first end of the elastic element 30 drives the first barrel 200 to move in a direction close to the first side plate 13, and the second end of the elastic element 30 drives the second barrel 300 to move in a direction close to the second side plate 14, that is, the elastic element 30 may drive the first barrel 200 and the second barrel 300 to move away from each other and correspondingly compress the first return spring 40 and the second return spring 42.
As shown in fig. 5, when the first connecting element 22 starts to rotate in a second direction (e.g., counterclockwise), the second connecting element 23 can move upward along the first limiting rod 21, at this time, the third end of the elastic element 30 moves upward, and both the first end and the second end of the elastic element 30 move inward, the first end of the elastic element 30 drives the first barrel 200 to move in a direction away from the first side plate 13, and the second end of the elastic element 30 drives the second barrel 300 to move in a direction away from the second side plate 14, that is, under the elastic force of the first return spring 40, the second return spring 42, and the elastic element 30, the first barrel 200 and the second barrel 300 can be driven to approach each other.
The pupil distance adjusting device 100 according to the embodiment of the present application can make the first barrel 200 and the second barrel 300 away from each other by rotating the first connecting member clockwise, and can make the first barrel 200 and the second barrel 300 approach each other by rotating the first connecting member clockwise.
