Detailed Description

Referring to fig. 1-8, the present invention relates to a dual-filter switch, comprising: the switcher body is arranged in the shell and comprises a base, a rocker arm, a moving piece 8 and a driving mechanism, wherein the base is provided with a wire frame 5, the moving piece 8 and the driving mechanism are arranged on the base, the driving mechanism drives the moving piece 8 to move through the rocker arm, the moving piece 8 is provided with a double-filter assembly 18, the double-filter assembly 18 comprises an infrared cut-off filter 9 and a full-transmission spectrum filter 10, and the infrared cut-off filter 9 and the full-transmission spectrum filter 10 are arranged side by side;

the upper surface of the shell is provided with a through hole 17 with internal threads, the lower surface of the shell is provided with a light hole 20 corresponding to the through hole 17, and the double-optical-filter component 18 is assembled between the through hole 17 and the light hole 20;

in the above solution, the through hole 17 can be used to install a short back focus lens, so that the short back focus lens can be downward extended to the surface of the dual-filter assembly 18, and thus some lenses with shorter focal length can still use the switch. Adopt inside the casing can effectually prevent that dust and steam from getting into the base, the phenomenon of avoiding shooing the light leak appears.

Further, the housing is provided with a convex rail 19, the convex rail 19 is used for supporting the moving plate 8, and the convex rail 19 can reduce friction between the moving plate 8 and the housing, so that the moving plate 8 can move more smoothly; in this embodiment, the number of the convex rails 19 is two, and the two convex rails 19 are arranged in parallel, which is defined herein for the purpose of making the moving plate 8 more stably placed on the convex rails 19, and improving the overall stability.

The edge of the moving piece 8 is provided with a connecting arm 15, the connecting arm 15 is connected with one end of the rocker arm, and the other end of the rocker arm is connected with the driving mechanism. The distance between the moving piece 8 and the rocker arm is increased through the connecting arm 15, the moment is increased, and when the rocker arm drives the moving piece 8 to move through acting force, the stress of the moving piece 8 is increased, so that the moving piece 8 is more sensitive to move. Specifically, the connecting arm 15 is provided with a strip-shaped hole 14, and clamping notches 11 are respectively arranged on two sides of the strip-shaped hole 14; the rocker arm comprises an arm plate 12 and a limiting column 6, the limiting column 6 is arranged at one end of the arm plate 12, and the limiting column 6 penetrates through the strip-shaped hole 14; the driving mechanism is connected with the other end of the arm plate 12 to drive the rocker arm to swing so as to drive the moving piece 8 to move. In this embodiment, the two sides of the strip-shaped hole 14 are both provided with a clamping notch 11; when spacing post 6 slides in behind the screens breach 11, screens breach 11 makes the rocking arm still can not be free removal when rocking externally for the switch has self-locking function, has solved the problem that the electromagnetism switch probably became invalid in the motion process.

Further, the driving mechanism comprises a U-shaped iron 3, a coil 4 and a magnet 7, the coil 4 is sleeved on the U-shaped iron 3, the magnet 7 is rotatably installed on the base, the magnet 7 is fixedly assembled with the rocker arm, and the coil 4 is connected with a lead 2 with a terminal 1; the base is provided with a positioning column, the magnet 7 is provided with a mounting hole 16, and the positioning column penetrates into the mounting hole 16; the other end of the arm plate 12 is provided with a mounting convex column 13 matched with the mounting hole 16, and the mounting convex column 13 penetrates into the mounting hole 16. After the current is supplied, the current flowing through the coil 4 magnetizes the U-shaped iron 3, so that the U-shaped iron 3 generates a magnetic field to interact with the magnetic field of the magnet 7. By changing the direction of the current, the direction of the magnetic field generated by the U-shaped iron 3 can be changed, so that the magnetic field of the U-shaped iron 3 and the magnetic field of the magnet 7 have different interactions, and the magnet 7 rotates in different directions under the action of the magnetic field. Because the magnet 7 is fixedly connected with the rocker arm, the rotation of the magnet 7 in different directions drives the rocker arm to swing in different directions, so that the movement of the movable piece 8 in different directions is driven; i.e. so that the moving blade 8 can advance and retreat, thereby effecting switching between the infrared cut filter 9 and the full transmission spectrum filter 10.

The above embodiments are only for describing the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and various modifications and improvements made by the technical solution of the present invention by those skilled in the art are all within the scope of the present invention as defined by the claims.
