Specific embodiment
Below by way of specific embodiment, the utility model will be further described.
Referring to figs. 1 to 4, a kind of adjustable reflecting camera lens, including lens group 1, curved reflector 2, lens mount
3。
Lens mount 3 includes lens group support 31, mirror mount 32；
Lens group 1 is installed in lens group support 31, and lens group support 31 is semicylindrical body, and cylinder inboard wall is equipped with to convex
The stiffening ring 311 risen, to guarantee that support has enough support forces to protect lens group 31；
Curved reflector 2 is installed in mirror mount 32, and curved reflector 2 is non-spherical reflector, and medial surface is
Reflecting surface, reflecting surface accept the light sent out by lens group 1, and curved reflector 2 is installed on reflection by three support connectors 4
On mirror support 32, support connector 4 includes a steering linkage member 41 and two roll adjustment connectors 42, three support connectors 4
It is arranged in triangle relation, and the stress point of steering linkage member 41 and the stress point of two roll adjustment connectors 42 are connected to form two-by-two
Equilateral triangle structure, steering linkage member 41 are set among 2 top of curved reflector, and two roll adjustment connectors 42 are respectively arranged on song
2 lower part two sides of face reflecting mirror.Steering linkage member 41 includes the nose bar 411 with spherical surface end being set on curved reflector 2, sets
