(3) utility model content
The purpose of this utility model is to intend a kind of opening and closing that come control gate by less electric power, magnetic force are provided, and a kind of little magnetic machinery door latch structure of door lock of firmer coupling mechanism force particularly can be provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of little magnetic machinery door latch structure comprises opposed in opposite directions two door-plates, it is characterized in that, the knuckling rod is set on the substrate of a door-plate, and active card ball mechanism is set on another door-plate,
Described knuckling rod is, the cylindrical rod that a protruding end is a ball on the substrate perpendicular to door-plate, and bulb diameter is greater than body diameter;
Described active card ball mechanism is:
Be the spherical cavity of cavity vertically be provided with one on the pedestal of flat board in the middle of, the spherical cavity internal diameter is greater than the bulb diameter of described knuckling rod;
At the oral area of spherical cavity, setting can change the limit ball controlling organization of caliber size.
Adopt the technical program, in the knuckling rod on the door-plate is inserted in the spherical cavity of active card ball mechanism on another door-plate, and can change the limit ball controlling organization of caliber size by the spherical cavity oral area, when bore during less than knuckling baseball portion diameter, just can stop extracting of knuckling rod, the rigid mechanical coupling mechanism force far above electromagnetic force is provided.
Described limit ball controlling organization is, at the bore of the nearly spherical cavity of wall portion of spherical cavity to offering at least two circular holes, in each circular hole, place ball, ball can move radially in circular hole, when each ball is close to the spherical cavity axle center, the circle diameter that surrounds is more than or equal to the body diameter of knuckling rod, less than knuckling baseball diameter, when each ball moves in the spherical cavity axle center dorsad, the circle diameter that surrounds is greater than the bulb diameter of knuckling rod, and moving radially by ball step trough and advance and retreat controlling organization of each ball formed.
Adopt the present technique feature, ball moves radially in the circular hole of spherical cavity wall portion, rolls freely, when ball is moved to the spherical cavity axle center by ball step trough and the extruding of advance and retreat controlling organization, near the cylinder of knuckling baseball subordinate side, the knuckling rod can not be extracted, and door is by safe locking.
Described ball step trough and advance and retreat controlling organization are: configuration one is nested with at the spherical cavity periphery and the slide block that can move along the spherical cavity axis on the pedestal of spherical cavity, the slide block inwall is offered the stepped hole that varies in size, aperture can reach described each ball is close to the spherical cavity axle center, the circle diameter that surrounds is more than or equal to the cylindrical rod diameter of knuckling rod, bulb diameter less than the knuckling rod, macropore can reach described each ball is moved in the spherical cavity axle center dorsad, and the circle diameter that surrounds is greater than the bulb diameter of knuckling rod; Slide block is positioned at the bottom of pedestal by the elastic force of spring, and slide block side shifting outward is subjected to the stop block of pedestal both sides to place restrictions on the position to the spherical cavity oral area; Slide block outer moves by outer machine drawing structure and applies or discharge pulling force.
