Detailed Description

Referring to fig. 1-5, the present invention relates to a self-locking mechanism for an IR-CUT dual-filter switch, comprising: the device comprises a base, a rocker arm, a moving piece 8 and a driving mechanism, wherein the moving piece 8, the rocker arm and the driving mechanism are arranged on the base, the base is also provided with a wire rack 5, the moving piece 8 is provided with a strip-shaped hole 14, and clamping notches 11 are 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. The movable sheet 8 is provided with a double-filter assembly, the double-filter assembly 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 in parallel.

In the scheme, the clamping notches 11 are arranged on the two sides of the strip-shaped hole 14; 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, a connecting arm 15 is arranged on the edge, close to the rocker arm, of the moving piece 8, and the strip-shaped hole 14 is formed in the connecting arm 15. 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.

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, and the magnet 7 is fixedly assembled with the rocker arm; 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 an installation convex column 13 matched with the installation hole 16, and the installation convex column 13 penetrates into the installation 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 plate 8 can advance and retreat, thereby effecting switching between the infrared cut filter 9 and the full transmission spectrum filter 10.

The utility model generates current after the terminal 1 is electrified, the U-shaped iron 3 passes through the coil 4 to generate an induction magnetic field, the magnet 7 is forced to rotate, the rocker arm is driven, and the moving piece 8 is driven to complete the switching between the infrared cut-off filter 9 and the full-transmission spectrum filter 10; after the switching, due to the clamping effect of the clamping gap 11, even if the attraction force of the magnet 7 is insufficient, the rocker arm can keep the switched state at any time; the problem that the electromagnetic switcher possibly fails in the motion process is solved.

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.
