Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention program is elaborated.
The mahjong machine fold mechanism that the present embodiment provides, is connected between the desktop bottom and supporting seat of mahjong machine, comprisesCasing 4, rotating shaft 3, cover plate 1, moving block 7 and delay switch 8. Rotating shaft 3 is supported on casing 4 upper ends, cover plate 1 lower surface establishThere is pin 11. Moving block 7 is located in casing 4, and moving block 7 is in transmission connection with cover plate 1, drives cover plate 1 at horizontal level and verticalBetween position, 3 rotate around the shaft. When being located at cover plate 1 and being horizontal, delay switch 8 in the frame of the corresponding side of pin 11, postponesSwitch 8 comprises lever 88, external broach spring 84, interior Compress Spring 85, is provided with the cylinder body 81 of upper and lower plunger shaft, interconnects and dividesBe not placed in upper piston 82 and lower piston 83 and the contact switch of upper and lower plunger shaft. Cylinder body 81 is placed in casing 4 outsides, lower pistonChamber is built-in with damping oil 87, lower piston 83 be provided with at least one connection hole, this hole for be communicated with separated by lower piston 83 underPlunger shaft, the two ends of interior Compress Spring 85 connect with the corresponding bottom of lower piston 83 and housing respectively, and lever 88 is rotationally connected withIn frame, form to be rotationally connected a little first arm of force and second arm of force as stressed fulcrum, the two ends of external broach spring 84 respectivelySecond arm of force of connection frame and lever 88, the end of second arm of force can conflict upper piston 82, the first arm of force ends and pin 11Corresponding, contact switch 810 is located at the top of upper piston 82 connecting rods. Contact switch 810 and motor communication connection, open contactPass 810 motor in closing course is still in running order.
Further, delay switch 8 also comprises sealing ring 86, sealing ring 86 be located at the accent place in lower piston chamber and with lower workPlug 83 is tightly connected.
The moving block 7 that the present embodiment adopts is driven and is rotated by a driving mechanism. Moving block 7 comprises turbine and top board 6, top board6 lower surface is connected with worm gear 72, and upper surface connects cover plate 1, and driving mechanism comprises worm gear 72 and worm screw, and worm screw rotationallyBe connected in frame, and rotate by a driven by motor, worm gear 72 is articulated with rotating shaft 3 meshing with worm screw. Worm gear 72 is the center of circleAngle is the fan-shaped of 90 degree.
The present embodiment also comprises two magnetic inductors, i.e. the first magnetic inductor 5, the second magnetic inductor 51. The first magnetic inductor 5Be located in the spacing hole 2 of casing with respect to rotating shaft one side, for detection of cover plate whether in vertical position. The second magnetic inductor 51Whether be located at casing is horizontal for detection of cover plate with respect to the top of delay switch one side. Magnetic inductor comprises HallSwitch, divider resistance, triode and light emitting diode, as Figure 11. The output of Hall switch is connected in the base stage of triode,The negative pole of light emitting diode is connected in the colelctor electrode of triode, the anodal power supply that connects, first, second magnetic inductor respectively with electricityMachine communication connection. Two magnetic inductors go out for Preliminary detection that cover plate 1 moves to respectively corresponding level, vertical position and to motorSend interrupt signal.
The mahjong machine fold mechanism that the present embodiment provides in the time that cover plate 1 will turn to horizontal level by vertical position as figure3, Fig. 4, do not conflict yet first arm of force of lever 88 of the pin 11 of cover plate 1 lower surface, the second arm of force conflict upper piston of lever 8882, the lower piston 83 that makes to be connected with upper piston 82 is pushed interior Compress Spring 85 and is carried out energy storage, now due to lower piston chamber and epicoeleThe volume of body reduces, and forms high pressure in the below of damping oil 87 and upper cavity. When turning to casing 4, cover plate 1 leaves necessarilyWhen in the gap, as Fig. 5, Fig. 6, pin 11 start to conflict first arm of force of lever 88, second arm of force starts to depart from upper piston 82, interiorUnder the gas pressure of the elastic potential energy release of Compress Spring 85 and lower piston chamber, upper cavity, upper lower piston starts to move up, byStep is pressed close to until the contact of conflict contact switch 810 works on as Fig. 7, Fig. 8 make motor. Due to inertia, upper lower piston can continueContinuous upwards a bit of distance, now the air pressure air pressure of lower piston chamber, upper cavity reduces, and interior Compress Spring 85 draws high upper and lower workPlug 83 produces resistance and finally makes its decline reach poised state. In the time that cover plate 1 turn to horizontal level by vertical position, pin11 depart from first arm of force of levers 88, and first arm of force that now 84, external broach spring can act on lever 88 will be lived it up and downPlug is pressed in cylinder body 81 by equilbrium position.
