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.
