In addition, it should be noted that in the present embodiment, the surfaces of the fixed plate 32 and the rotating plate 33 connected to the reflector body are coated with a light-blocking coating, such as a black coating, to reduce interference with the imaging of the mirror coating 311.
In addition, the mirror support further includes: a connecting piece 5 for movably connecting two adjacent reflector bodies 31; a locking member for locking the mirror body 31 to the connecting member 5; wherein, the reflector body 31 is locked by the locking member after rotating to a preset angle on the connecting member 5.
Thus, the adjustment and fixation of the rotation angle of the mirror body 31 are achieved by the cooperation of the locking member and the connecting member 5. In addition, the angle adjustment of a single reflector 3 can be realized through the connecting piece 5, and adjacent reflectors 3 can be connected together to form end-to-end connection. The number of the connecting pieces 5 in this embodiment is the same as the number of the reflecting mirrors 3. Moreover, the fixed connection between the reflector 3 and the bearing platform 2 can be realized through the connecting piece 5, and the rotation adjustment of the reflector 3 is not influenced.
Specifically, as shown in fig. 8, the connecting member 5 in this embodiment mainly includes a first body 51 having a first sliding slot 511, a second body 52 connected to the first body 51 and having a second sliding slot 521, a rotating shaft connected to one of the mirrors and inserted into the first sliding slot 511, and a rotating shaft connected to the other of the mirrors and inserted into the second sliding slot 521. Wherein, the first body 51 is rotatably connected with the rotating shaft inserted into the rotating hole 331 of one of the reflectors 3 through the first sliding slot 511, and the second body 52 is rotatably connected with the rotating shaft inserted into the rotating hole 331 of the other reflector 3 through the second sliding slot 521; the retaining member includes: and the locking nut is used for locking and connecting the rotating shaft. The first body 51 and the second body 52 are preferably perpendicular to each other, so that the shape enclosed by the mirrors 3 after being connected is rectangular.
Therefore, the rotating shaft slides between the corresponding sliding grooves to realize the rotation of the reflecting mirror 3, and then the rotating shaft can be locked by the locking nut after rotating to a set angle. Obviously, other components may be used in the present embodiment instead of the lock nut to lock the rotating shaft, and the present embodiment is not limited in particular. In addition, it should be noted that the first sliding slot 511 and the second sliding slot 521 in this embodiment may also be disposed on the reflector body 31, and the angle of the reflector 3 is adjusted and fixed by a rotating shaft disposed on the connecting member 5, which is not described herein again.
Preferably, the first sliding slot 511 and the second sliding slot 521 in this embodiment are both arc-shaped slots. So that the rotation of the reflecting mirror 3 is a smooth circular rotation by the arc-shaped groove.
Further, as shown in fig. 8, the connecting member 5 includes: a third body 53 connected to the first body 51 and the second body 52 and detachably connected to the receiving platform 2. Through the detachable connection between the third body 53 and the bottom plate 22 of the receiving platform 2, the connection between the reflector 3 and the receiving platform 2 is realized, and the rotation thereof is not influenced.
The above embodiments are merely to illustrate the technical solution of the present invention, not to limit the same, and the present invention has been described in detail with reference to the preferred embodiments. It will be understood by those skilled in the art that various modifications and equivalent arrangements may be made without departing from the spirit and scope of the present invention and it is intended to cover the appended claims.
