Description

Permanent magnetic safety lock

The utility model has related to a kind of lock, specifically a kind of permanent magnetism safety lock.

At present, existing various safety locks are varied, as safety lock of pin tumbler lock, mechanical cipher type lock, charged brain or the like, however these safety locks, it is higher to exist mutual opening rate, and key is easily by shortcomings such as imitated, processed complex, cost height.New development both at home and abroad in recent years a kind of magnetic lock, magnetic lock as Chinese patent CN87204860, the structure of this lock, be that the form by dislocation leaves 13 magnetic core acupuncture points on lock core, select for use four caves to arrange during for conversion arbitrarily, because the magnetic core acupuncture point on the lock core is many, the amount of causing a deviation is inevitable, several magnetic cores that slide simultaneously want to slide into normally, skid off the flashboard acupuncture point and do not break down, and have all increased the difficulty that adds man-hour, have caused the cost increasing.Chinese patent CN2058928U discloses a kind of " magnetic safety lock ", it is characterized in that the part of inserting lock core at key is equipped with special magnetic sheet, and the bottom of every lock pearl in the lock core all is embedded with a lock pearl magnetic sheet, this lock is easily by imitated, be easy to locked, processing inconvenience.

The purpose of this utility model has been fundamentally to improve the safety of lock, and it is more safe and reliable that lock is become, and cost is low, and the life-span is long, and processing and assembling are easy to the permanent magnetism safety lock.

The purpose of this utility model realizes by following means.

A kind of permanent magnetism safety lock, by the lock core in lock body, the lock body with insert key in the lockhole etc. and form, the characteristic that it is characterized in that utilizing the same sex of permanent-magnet material to repel each other, change the pellet shot from a slingshot in the lock into magnetic marble whole or in part, and make magnetic marble by different polarity, different positions and arrangement mode are installed in and block lock core in lock core and the lock body and do not allow its rotation, and at the magnet that is equipped with same polarity and same arrangement mode on the key, the status requirement that is installed in the magnet in the key is corresponding with the position of corresponding magnetic marble.Wherein lock body, lock core and key are made by non-magnet materials such as copper, aluminium, stainless steel, plastics.

The utility model provides a kind of permanent magnetism safety lock, it is characterized in that changing the pellet shot from a slingshot in the lock into magnetic marble whole or in part, key has also been installed magnet, thereby make lock except the pellet shot from a slingshot, teeth and the function that possess common lock, magnetic marble, magnetic key have been used, and magnetic marble and magnet can not touch less than, hand soon in lock and on the key, have improved the safety performance of locking in original safety widely.Simultaneously, it has overcome existing safety lock complex structure, open, lock very numerous and diverse, the shortcoming that cost is high, processing and assembling are easily, safe and reliable, cost is low, the life-span is long, it is easy to open and lock, can on family, automobile, motorcycle, bicycle, safety cabinet, all kinds of door and window, use widely, be even more ideal safety lock.

The utility model has following accompanying drawing.

Fig. 1 is the assembling drawing of the permanent magnetism safety lock of band tooth.

Fig. 2 is the assembling drawing that has only the permanent magnetism safety lock of magnetic marble.

Below in conjunction with accompanying drawing the utility model is further described.

Embodiment 1.

As shown in Figure 1, be the assembling drawing of permanent magnetism safety lock of band tooth.Wherein lock body 1, lock core 2 and key 3 adopt aluminium to make, can block lock core 2 in lock core 2 and 1 li installation of lock body and not allow the magnetic marble 4 of its rotation, 4 ' and 10,10 ', magnetic marble 4,4 ' and 10,10 ' make by the NdFeB rear-earth magnetic material, the N utmost point of magnetic marble 4 points to lock core 2, extremely adjacent by lead sealing 7 securing springs 6 with the S of magnetic marble 4, magnetic marble 4 ' the S utmost point point to lock core 2, by the securing springs 6 of lead sealing 7 and magnetic marble 4 ' N extremely adjacent, on key 3 with magnetic marble 4, on the 4 ' corresponding position magnet 9 is installed, guarantees magnetic marble 4,4 ' be subjected to mutual expelling force.Same method is installed magnetic marble 10,10 ' and magnet 11, must guarantee the power of magnetic marble 10,10 ' repelled each other.Magnet the 9, the 11st is made by the NdFeB rear-earth magnetic material.When key 3 inserts lockholes, have in the former lockmaking of copper marble 5() and after shaped as key bit 8 coincide, magnetic marble 4,4 ' and 10,10 ' quilt scolded, lock core 2 can rotate, and reaches the purpose of opening lock.After key 3 is extracted, magnetic marble 4,4 ' and 10,10 ', copper marble 5 is pushed back by lead sealing 7 securing springs 6 to be blocked lock core 2 again and not to allow its rotation between lock core 2 and the lock body 1, and lock has been locked.The lock housing 12 that wraps in lock body 1 outside is made by iron sheet.

Embodiment 2.

As shown in Figure 2, be the assembling drawing of the permanent magnetism safety lock that has only magnetic marble.Wherein as different from Example 1: lock body 1, lock core 2 and key 3 are made of copper, magnetic marble 4,4 ' and 10,10 ', magnet 9,10th is made by non-rareearth magnetic materials such as aluminium nickel cobalts, is not with tooth 8 on the key 3, be not with non magnetic pellets shot from a slingshot such as copper marble 5 in the lock, the lock housing 12 that wraps in lock body 1 outside can be made also and can be made by non-magnet material by permeability magnetic material.

Claims (4)

1, a kind of permanent magnetism safety lock, by the lock core 2 in lock body 1, the lock body 1, insert key 3 compositions such as grade in the lockhole, it is characterized in that by different polarity, different arrangement mode and different positions magnetic marble 4 being installed in lock body 1 and the lock core 2,4 ' and 10,10 ', the corresponding installation in the key 3 with same polarity and same arrangement mode magnet 9 and 11.
