Abstract
The invention relates to a small angle swing reflector mechanical position limiter of optical system, which comprises fixing a limiting block on another surface of a reflector base opposite to the reflector, flexibly connecting a limiting rod on the bottom cover of the optical system, inserting one end of the limiting rod into the hole on the bottom cover of the optical system. When the optical system is idle as vehicle transmission of instrument or device, th limiting rod via elastic force is clamped with the limiting block via the end inserted into the bottom cover of the optical system to fix the reflector base and avoid reflector damage. The invention has simple structure and simple application, which is suitable for vehicle-mount large optical instrument or device.
Description
Technical field
The present invention relates to the two dimensional reflection mirror in a kind of optical system, mechanical stop limiter for micro angle swinging reflector in particularly a kind of optical system.
Background technology
In optical system, usually need to use catoptron to adjust light-struck direction, make the direction outgoing of the light that incides on the catoptron along system requirements.The control device of two dimensional reflection mirror mainly is made of inner frame, outside framework and two motors in the optical system at present; The mirror unit of stationary mirror is fixedlyed connected with inner frame, and inner frame connects with outside framework is movable, and inner frame and outside framework are rotated by two Electric Machine Control, and mirror unit is rotated on two-dimensional direction with inner frame and outside framework.Owing to be installed in the device that mirror unit in this two dimensional reflection mirror control device does not make its location, cause optical system when off working state, particularly produce vibrations in the vehicle-mounted transportation of instrument or equipment, cause the catoptron damage.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of when the optical system off working state, particularly in the vehicle-mounted transportation of instrument or equipment with the mirror unit stationkeeping, thereby avoid causing the mechanical stop limiter for micro angle swinging reflector of catoptron damage.
Mechanical stop limiter for micro angle swinging reflector of the present invention comprises limited block, gag lever post; Described limited block is fixed on mirror unit another surface relative with catoptron; The bottom resilient connection of gag lever post and optical system, and the one end is stretched into by the hole on the optical system bottom; When the optical system off working state, an end and limited block clamping that gag lever post is stretched into by the hole on the optical system bottom are with the mirror unit stationkeeping.
When optical system was in running order, the pulling gag lever post broke away from itself and limited block, and mirror unit just can rotate on two-dimensional direction with inner frame and outside framework.When optical system is in off working state, particularly in the vehicle-mounted transportation of instrument or equipment, gag lever post relies on the elastic force effect, and it stretches into an end and the limited block clamping of optical system bottom, just can be with the mirror unit stationkeeping, thus avoid causing the catoptron damage.The present invention is simple in structure, and is easy to use, can be used for vehicle-mounted large-scale optical instrument or equipment.
Described gag lever post stretches on the end end face of optical system inside and is processed with hole clipping; An end face of limited block is processed with and the corresponding dop of this hole clipping; When optical system was in off working state, the dop of limited block end face was stuck in the hole clipping of gag lever post end face, made the mirror unit stationkeeping that is fixedly connected with limited block.
The dop of the hole clipping of described gag lever post end face and limited block end face can be conical and other can satisfy the shape of the operating angle scope of rapid control reflector when in running order.
Described gag lever post is made of cross bar and the vertical rod two parts that connect that interfix; The upper end of the lower end of last cylinder, following cylinder and the bottom three of optical system are fixedly connected; Vertical rod is by passing in last cylinder and the following cylinder, and cross bar is stuck in the top of cylinder; The part of cylinder had a boss under vertical rod was arranged in, and spring housing is in the part between last cylinder lower end and boss on the vertical rod.When optical system is in running order, the pulling cross bar, vertical rod is upwards mentioned, length of spring compressed, vertical rod lower end and limited block break away from, and mirror unit just can rotate on two-dimensional direction with inner frame and outside framework.When optical system was in off working state, vertical rod relied on the acting force of spring, and it stretches into an end and the limited block clamping of optical system bottom and is pressed together, with the mirror unit stationkeeping.
Between described vertical rod and the last cylinder, go up on cylinder lower end and the following cylinder between, be hermetic seal between time cylinder lower end and the optical system bottom, enter optical system to prevent dust.
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
Description of drawings
Fig. 1 is a front view of the present invention.1 mirror unit among the figure, 2 limited blocks, 3 dops, 4 bottoms, 5 cross bars, 6 vertical rods, 7 boss, 8 hole clippings, cylinder on 9,10 times cylinders, 11 springs, 12,13,14 sealing gaskets.
Embodiment
