Embodiment

Below in conjunction with accompanying drawing, the present invention program is described in detail.

The delay switch 21 that the present embodiment provides, is located on the second flip body 20.The side of the first flip body 19 is articulated with the second flip body 20, freely can rotate relative to the second flip body 20.This delay switch 21 comprise lever 8, external broach spring 4, interior Compress Spring 5, be provided with upper and lower plunger shaft cylinder body 1, be interconnected and be placed in the upper piston 2 of upper and lower plunger shaft and lower piston 3 and contact switch 16 respectively.The lower end of the first flip body 19 is provided with touches pin 10, and cylinder body 1 is placed on the second flip body 20.Lower piston chamber 12 is built-in with damping oil, and lower piston 3 is provided with at least one intercommunicating pore 9.This hole is for being communicated with the lower piston chamber 12 of being separated by lower piston 3.The two ends of interior Compress Spring 5 are connected with the bottom of lower piston 3 and cylinder body 1 respectively.Lever 8 is rotationally connected with on the second flip body 20, and being formed to be rotationally connected is a little first arm of force and second arm of force of fulcrum force.The two ends of external broach spring 4 connect second arm of force of the second flip body 20 and lever 8 respectively, and can conflict upper piston 2 in the end of second arm of force, the first arm of force end is corresponding with shake-up pin 10, and contact switch 13 is located at the top of upper piston.

Further, this delay switch 21 also comprises sealing ring 6, and the accent place in lower piston chamber is located at by sealing ring 6 and piston rod is tightly connected.

Further, contact switch 13 and driving mechanism communicate to connect, and make contact switch 13 driving mechanism in closing course that the first flip body 19 can be driven to rotate.

Further, lever 8 is provided with groove, and the corresponding end of external broach spring and lever second arm of force is provided with draw ring 17, and external broach spring 4 realizes being connected with groove 18 clamping by draw ring 17 with second arm of force.

Above-mentioned delay switch 21 can be used on switching mechanism as shown in Figure 1, this mechanism is by having the first rotor and second rotor of mutual rotation relation and being made up of motor-driven transmission mechanism, first rotor is a returning face plate 15, second rotor is a box body 14, transmission mechanism is Worm and worm-wheel gearing, be placed in described box body, worm screw is driven by motor, worm gear is incomplete 1/4 worm gear, returning face plate to be connected on this band worm gear and the rotation done with worm gear wheel relative to box body, make returning face plate by rotate to the upper transverse plane of box body press close to or away from.Generally rotating mechanism is often difficult to make returning face plate turn to the position fitting in transverse plane on the second rotor exactly, the collision formed the second rotor to prevent from rotating position, usually leave running clearance, make the first rotor can not really to fit on the second rotor on transverse plane.

Delay switch 21 device of the present invention being placed in the outer wall of box body 14, as Fig. 2, being connected to touching pin the position that returning face plate medial surface corresponds to first arm of force on lever 8, and by contact switch 16 cross-under on the power circuit of motor.When needs returning face plate turn to fit with box body time, driven by motor is rotated with worm screw, worm gear is by producing corresponding rotation to worm engaging, drive returning face plate to rotate to rotate to pressing close to cassette upper end face, when returning face plate is about to cassette upper end face as Fig. 1, Fig. 2, first arm of force of the shake-up pin 10 of returning face plate 15 lower surface conflict lever 8 not yet, second arm of force conflict upper piston 2 of lever 8, make the lower piston 3 be connected with upper piston 2 push interior Compress Spring 5 and carry out energy storage, now because the volume of lower piston chamber and upper cavity reduces, high pressure is formed in the below of damping oil 7 and upper cavity.When returning face plate 15 will turn to leave certain interval with the second flip body 20 time, as Fig. 5, Fig. 6, touch pin 10 to start to conflict first arm of force of lever 8, second arm of force starts to depart from upper piston 2, interior Compress Spring 5 elastic potential energy release and lower piston chamber, upper cavity gas pressure under, upper lower piston starts to move up, and progressively presses close to until the contact of conflict contact switch 13, as Fig. 7 makes motor work on, returning face plate 15 is driven to fit completely box body 14.Due to inertia, upper lower piston can continue upwards a bit of distance, and now the air pressure air pressure of lower piston chamber, upper cavity reduces, and interior Compress Spring 85 draws high upper and lower piston generation resistance and finally makes it decline and reaches poised state.When returning face plate 15 turn to horizontal level by vertical position, touch pin 10 and depart from first arm of force of lever 8, first arm of force that now 4, external broach spring can act on lever 8 makes it be pressed in cylinder body 1 by equilbrium position by upper lower piston.
