Description
(1) technical field
The present invention is a kind of parts of door lock, particularly relates to a kind of door and doorframe, or two fans move door, or a fan fixes a fan and move, and both move in opposite directions and make each other by to hitting locking, the uncommitted a kind of syndeton that can't open separation.
(2) background technology
As everyone knows, at door lock, particularly a kind of being used for door and doorframe, or two fans move door, an or fan fixes a fan and move, both move in opposite directions and make each other by to hitting the mechanism of locking, generally all adopt magnetic door lock.The primary structure of magnetic door lock is, electromagnet is fixed on a side door or the doorframe, and the iron plate of continuing is fixed on the door-plate with the electromagnet opposite position.This type of door lock has a kind of special advantage, promptly the door pass is fashionable, inhale mutually by magnetic force between the two and close, steadily and suction bigger, be difficult for being opened by general external force, when needs open the door, cut off the electricity supply, electromagnet discharges with the iron plate of continuing and opens automatically, and the place of opening door lock can be away from door, even power on/off that can the straighforward operation electromagnet, very easy to use.
Along with the advantage of this type of door lock is familiar with, its scope of application is also in continuous expansion, for example places such as bulk storage plant, bank, garden, people wish that not only this type of door lock is arranged, and wish more powerful electromagnetic attraction can be provided, reinforce the suction of closing of door, make to become safer, relieved in the door.
Magnetic force be with a constant, the saturated flux density of material square and the surface area three be directly proportional, promptly equal above three's product.In order to improve magnetic force, under the situation that constant, the saturated flux density of material are fixed, generally can only be to improve surface area, yet the surface area of door usually is limited, and strengthens the necessary again material input that increases of surface area of magnetic material, has increased cost and price, the market of product will be influenced, otherwise the suction deficiency, it is not tight to close door, and safety problem makes the people worry more.
Market has proposed higher, a more anxious problem and requirement, and wishing is not increasing big cost input, and the less magnetic force of change expense, electric power and produce and reach stronger adhesion is arranged between two increase the safety of door lock.
(3) summary of the invention
The objective of the invention is to intend providing a kind of opening and closing that come control gate by less electric power, magnetic force, a kind of door lock syndeton of firmer coupling mechanism force particularly can be provided.
The objective of the invention is to be achieved through the following technical solutions:
A kind of syndeton of door lock 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.
The employing the technical program, when two fan doors were opened separation, slide block was subjected to the elastic force effect of spring, and the normal stop bit of quilt is in the bottom near pedestal; When slippaging for two, slide block is subjected to the control of outer machine drawing structure, applying pulling force makes slide block touch knuckling rod one side, two are closed, and at slide block when knuckling rod one side draught is attached, suction has overcome the elastic force of spring, slide block is moved into the stop block of pedestal both sides and places restrictions at the spherical cavity mouth position, the slide block inwall is offered the stepped hole that varies in size, also become aperture by macropore, aperture forces in the circular hole of ball in spherical cavity wall portion and moves to shaft core position, and each ball is close to the cylindrical rod of knuckling rod, and be stuck in the lower end, bulb of knuckling rod, make the bulb outward layback go out.Because aperture is that rigid material is made, do not become big possibility, therefore the strength that the bulb of knuckling rod is blocked is very big, also therefore be converted to, make to have produced the very big power of closing of closing between the two fan doors, allow that this closes the power of closing can be great as long as make the material of aperture, and the electromagnetic force that the electromagnetism slide block is outwards moved is very little, only need overcome the spring force that the electromagnetism slide block resets and get final product.Embody thus by very little electromagnetic force can realize producing almost can be very huge between the two fan doors the power of closing of closing.In the time will opening door once again, as long as discharge the pulling force of outer machine drawing structure, spring slips into slide block lightly to base bottom, the stepped hole that the slide block inwall is offered has been retracted in the macropore again, ball can radially outward move, the circumference that ball surrounds is greater than the bulb diameter of knuckling rod, and spherical cavity is withdrawed from together with knuckling rod integral body in the bulb, and two fan doors are again by controlled opening like a cork.
