Also have minority optical filter switch to adopt the principle of electromagnetic induction, around optical filter, load onto coil, and in the relevant position fixing on magnet, the electric current that utilizes coil changes the magnetic force direction of switch by situation, comes and the magnet effect.Make the optical filter side-to-side movement change screening-mode, but this optical filter switch need make product do very thickly with coil stationary around the optical filter fixed mount, has increased the volume of product.And it installs trouble, requires high to coil and magnet.
Summary of the invention
The present invention considers that the optical filter switch is accomplished is thin as much as possible, makes its requirement that can meet various use occasions, has proposed a kind of optical filter switch, solve present optical filter switch thickness big, trouble, problem that cost is high be installed.
The present invention adopts following technical scheme to realize:
A kind of ultrasonic imaging delay control method, a kind of optical filter switch, it comprises base, cover plate, optical filter and switch, described base includes a switch placed cavity and an optical filter placed cavity, described optical filter placed cavity comprises base plate and side plate, on the described base plate light hole is arranged, between described optical filter placed cavity and the described optical filter track-type facilities is arranged, have on the described optical filter along logical sheet of the fixing side by side visible light of described track-type facilities guide rail direction and the logical sheet of invisible light, described optical filter is having the push rod that stretches out near described switch one side, described switch comprises a holder, two coils and a magnet rotor, described two coils are separately fixed at described holder both sides, described magnet rotor turning set is connected on the described holder, described magnet rotor upper end is fixed with a swing arm, described swing arm and described push rod cooperate the described push rod of promotion, and described push rod drives described optical filter and moves in described track-type facilities, and described cover plate cooperates with described base.After adopting this structure, can make the magnetic force rotor rotation by the direction of current that changes coil, the rotating band movable pendulum movable arm swinging of magnetic force rotor, push rod is released or retracted to swing arm again, push rod drives optical filter again along guide rail direction move left and right, reaches the purpose of switching logical mating plate.And this structure at optical filter part parts seldom, can do very thinly as much as possible.
The logical sheet of described invisible light is the logical sheet of infrared light.
Described holder is a reference column, and described magnet rotor centre bit is equipped with the circular hole that cooperates with described reference column.
Described magnet rotor is a columnar magnet.
One projection is arranged on the described swing arm, have a horizontal elongated slot on the described push rod, described projection is enclosed within the described elongated slot.Laterally the setting of elongated slot makes projection that certain activity space can be arranged in elongated slot, is unlikely to make optical filter stuck.
Described track-type facilities is the guide-track groove that is positioned at the projection on the described base plate and is positioned at described optical filter side, and described projection is socketed in the described guide-track groove.The setting of this track-type facilities can not thickeied optical filter, and simple in structure.
The side plate upper end of described optical filter placed cavity is extended with baffle plate.Baffle plate plays certain fixation to optical filter.
There is projection described cover plate inboard.Projection can prevent beating of optical filter.
Description of drawings
Fig. 1 is the structural drawing of the embodiment of the invention.
