Improved plug-in ball type magnetic lock
The utility model belongs to the lock class, and the spherical magnetic lock tapered end of particularly a kind of improved card insert type is suitable for making door lock.
Along with science and technology development, the spherical magnetic lock of card insert type makes man-hour progressively be subjected to people's welcome with advantages such as convenience just with its good confidentiality.The structure of the spherical magnetic lock tapered end of existing card insert type mainly is made up of positioning disk (1), rotating disk (2), rotating disk shell (3), lock-bit magnetic post (4), magnetic card key (5), T-piece (6) and rotating disk back-moving spring (7) as shown in Figure 1.This lock is work like this: after magnetic card key (5) inserts rotating disk (2), under corresponding magnetic patch (8) acts in magnetic card key (5), the lock-bit magnetic post (4) of heteropolarity is sucked in the rotating disk (2), the lock-bit magnetic post (4) of same polarity then is open, its pellet shot from a slingshot (9) is pushed in the positioning disk (1), the plane of rotation of rotating disk (2) and positioning disk (1) no longer is subjected to the constraint of lock-bit magnetic post (4) and pellet shot from a slingshot (9), can drive T-piece (6) rotation under the effect of hand-power unlocking mechanism is opened.In case extract magnetic card key (4) out, lock-bit magnetic post (4) resets under the effect of back-moving spring (10), again rotating disk (2) is locked.After practice after a while, this tapered end still has the following disadvantages: each lock-bit magnetic post of the first is all practical back-moving spring, magnetic sheet must adopt strong magnetic just can overcome the elastic force of back-moving spring, so its magnetic force damages other approaching with it band magnetic recording article easily; It two is that back-moving spring has occupied certain area, makes the magnetic code of existing tapered end arrange figure place and can only be discharged to eight, and confidentiality is desirable not enough.
The purpose of this utility model is the deficiency at the spherical Magnetic lock of existing card insert type, provides a kind of structure card insert type comparatively simple, reasonable and that magnetic code arrangement figure place is high spherical magnetic lock tapered end.
Task of the present utility model realizes by this way: as shown in Figure 3, this tapered end includes positioning disk (1), rotating disk (2), rotating disk shell (3), lock-bit magnetic post (4), magnetic card key (5), T-piece (6) and rotating disk back-moving spring (7), it is characterized in that in the magnetic card guide groove (11) of rotating disk shell (3), being provided with a magnetic conduction slide plate (12) with rotating disk (2) end face balance, between magnetic conduction slide plate (12) and rotating disk shell (3), be provided with a compression spring (13), go up magnetic patch (8) the employing identical polarity corresponding at magnetic card key (5) with lock-bit magnetic post (4), after in magnetic card key (5) inserts rotating disk shell (3), its magnetic patch (8) enters in the pin-and-hole (15) of positioning disk (1) with the pin-and-hole (14) that the repulsion that lock-bit magnetic post (4) produces should make each lock-bit magnetic post (4) break away from rotating disk (2).
The utility model is work like this: when magnetic card key (5) does not insert magnetic card guide groove (11) before, magnetic conduction slide plate (12) is close to rotating disk (2) under the effect of spring (13), because magnetic conduction slide plate (12) is a magnetic conduction, under the effect of magnetic force, lock-bit magnetic post (4) holds magnetic conduction slide plate (12) toward magnetic conduction slide plate (12) motion, with rotating disk (2) and positioning disk (1) the locking rotating disk (2) that connects together, rotating disk can not rotate, and unlocking mechanism can't be opened; After magnetic card key (5) inserts magnetic card guide groove (11), magnetic conduction slide plate (12) is pushed open, its inner corresponding magnetic patch (8) is because its magnetic is identical with corresponding negative or positive electrode lock-bit magnetic post (4), the magnetic force that the same sex that is produced is repelled each other is pushed lock-bit magnetic post (4) open, and make it to break away from fully rotating disk (2) and enter in the positioning disk (1), positioning disk (1) promptly is disengaged the locking of rotating disk (2), drives T-piece (6) rotation by manual turntable shell (3) by rotating disk (2) unlocking mechanism is opened.
From structure of the present utility model as can be known: owing to cancelled the back-moving spring of lock-bit magnetic post (4), both can simplify the structure, reduce cost, can adopt the projected area of weak magnetic and minimizing lock-bit magnetic post (4) again, make magnetic code arrange figure place and can increase to 12, improve confidentiality greatly, overcome the deficiency of prior art effectively.

As shown in Figure 3, positioning disk of the present utility model (1) is connected in aggregates with location-plate (17) with tapered end bassoon (21) by screw (16).The rotating disk of flange-like (2) passes the centre bore of positioning disk (1) with its quill shaft, and connects together with spacing the making it of shaft block ring (22), and rotating disk (2) can rotate with respect to positioning disk (1).On rotating disk (2) and positioning disk (1), have identical pin-and-hole (14 and 15), the degree of depth of pin-and-hole (15) should be equal to or slightly greater than the length of lock-bit magnetic post (4), so that can enter the rotation that does not influence rotating disk in the positioning disk (1) fully under the magneticaction that repels each other.As for the thickness of rotating disk (2), promptly the degree of depth of pin-and-hole (14) can decide according to the size of the magnetic force that repels each other, and the magnetic patch (8) in the magnetic card key (5) should be greater than the thickness of pin-and-hole (14) with the distance that lock-bit magnetic post (4) repels each other.Rotating disk shell (3) is enclosed within rotating disk (2) and upward is connected in aggregates by screw or riveted joint with rotating disk (2).Have the magnetic card mouth on rotating disk (2), and be provided with a magnetic card guide groove (11) within it, magnetic conduction slide plate (12) is arranged on the magnetic card guide groove (11), and compression spring (13) places between rotating disk shell (3) inner face and the magnetic conduction slide plate (12).Back-moving spring (7) is arranged on the end of rotating disk (2) quill shaft, and T-piece (6) places on the rotating disk (2) by the groove of rotating disk (2) quill shaft end, and by the torsionspring that resets they is linked together.
In order to make magnetic conduction slide plate (12) can hold lock-bit magnetic post (4) preferably, the most handy pure iron of magnetic conduction slide plate (12) is made.The available magnet of lock-bit magnetic post (4) is made, but the most handy copper sheathing is equipped with a magnet and makes at its front end, can improve the abrasion resistance of lock-bit magnetic post (4).In order to cooperate the improved structure of the utility model, magnetic card key (5) is preferably by magnetic card shell (16), demarcation strip (17) and panel (18) riveted form, magnetic patch (8) is located in the locating hole of demarcation strip (17), magnetic card shell (16) is made with nonmagnetic Stainless Steel sheet, panel (18) is with there being magnetic Stainless Steel sheet to make, to form magnetic circuit and shielding.In order to control the rotation direction and the rotational angle of rotating disk (2), on positioning disk (1), be provided with fan groove (19), go up correspondence at rotating disk (2) and be provided with the projection (20) that cooperates with fan groove (19).
