Description

Lock

[technical field]

The utility model relates to a kind of improvement invention of lockset.

[background technology]

Along with the progress of society and the perfect further of anti-theft measure, the various lock that can be suitable for different occasion arises at the historic moment, lock comprises common lock, coded lock, induction lock etc., but traditional common lock, ubiquity is easy to by the problem of technical unlocking, and theftproof performance is undesirable.

[summary of the invention]

The utility model provides a kind of lock with the good advantage of theftproof performance.

The utility model is implemented by the following technical programs:

Lock, by key, lock housing and lock core assembly composition, key opens lockset by unlatching end face and lock core component touch, it is characterized in that: the unlatching end face of key lays multiple installing hole A and multiple installing hole B, installing hole A is built with S pole the first magnet down, installing hole B is built with N pole the second magnet down, lock core assembly rotates setting in lock housing, lock core assembly comprises lock core, lock dog, N pole the first bar magnet upward, S pole the second bar magnet upward and shifting block, plug face is provided with the unlatching end face of locating slot valid key, shifting block arranges in lock core bottom and is fixedly connected with lock core, leaving transverse holes between shifting block and lock core allows described lock dog do horizontal sliding action wherein, the bottom of lock dog is provided with the stage clip laterally put, under stage clip effect, the head of lock dog is against the internal chamber wall of lock housing, the internal chamber wall of lock housing is provided with lockset " unlatching " and " locking " stopper slot, the lower surface of lock core is provided with the pin-and-hole a corresponding with installing hole A and the pin-and-hole b corresponding with installing hole B, the upper surface of lock dog is provided with the pin-and-hole c corresponding with pin-and-hole a and the pin-and-hole d corresponding with pin-and-hole b, first bar magnet is actively installed in pin-and-hole a, expose to the lower surface of lock core bottom it after first bar magnet carries out magnetic absorption by described lock dog and be inserted in pin-and-hole c, second bar magnet is actively installed in pin-and-hole b, expose to the lower surface of lock core bottom it after second bar magnet carries out magnetic absorption by described lock dog and be inserted in pin-and-hole d.

In technique scheme, after only having the unlatching end face of the key of correct pairing and plug face to aim to contact, first bar magnet of lock core inside and the second bar magnet just can overcome the magnetic adsorptive power between lock dog and adsorbed by the first magnet of Keyed interior and the second magnet simultaneously and carry out upper mobile work, such lock core could rotate to open lockset, the difficulty of technical unlocking is very large, so effectively can improve the theftproof performance of lockset.

[accompanying drawing explanation]

The utility model has following accompanying drawing:

Fig. 1 is structural representation of the present utility model.

[detailed description of the invention]

As shown in the figure, lock of the present utility model, by key 1, lock housing 8 and lock core assembly composition, key 1 opens lockset by unlatching end face and lock core component touch, the unlatching end face of key 1 lays multiple installing hole A and multiple installing hole B, installing hole A is built with S pole the first magnet 2 down, installing hole B is built with N pole the second magnet 12 down, the unlatching end face diaphragm 11 of key 1 covers, lock core assembly rotates setting in lock housing 8, lock core assembly comprises lock core 3, lock dog 5, N pole the first bar magnet 4 upward, S pole the second bar magnet 10 upward and shifting block 7, lock core 3 surface is provided with the unlatching end face of locating slot 31 valid key 1, shifting block 7 arranges in lock core 3 bottom and is fixedly connected with lock core 3, leaving transverse holes 9 between shifting block 7 and lock core 3 allows described lock dog 5 do horizontal sliding action wherein, the bottom of lock dog 5 is provided with the stage clip 6 laterally put, under stage clip effect, the head of lock dog 5 is against the internal chamber wall of lock housing 8, the internal chamber wall of lock housing 8 is provided with lockset " unlatching " and " locking " stopper slot 81, the lower surface of lock core 3 is provided with the pin-and-hole a corresponding with installing hole A and the pin-and-hole b corresponding with installing hole B, the upper surface of lock dog 5 is provided with the pin-and-hole c corresponding with pin-and-hole a and the pin-and-hole d corresponding with pin-and-hole b, described lock dog 5 adopts ferrous material, first bar magnet 4 is actively installed in pin-and-hole a, expose to the lower surface of lock core 3 bottom it after first bar magnet 4 is carried out magnetic absorption by described lock dog 5 and be inserted in pin-and-hole c, second bar magnet 10 is actively installed in pin-and-hole b, expose to the lower surface of lock core 3 bottom it after second bar magnet 10 is carried out magnetic absorption by described lock dog 5 and be inserted in pin-and-hole d, described lock core 3 adopts copper material.

Above-mentioned lockset is performed such to be opened with antitheft: under peacetime state, bottom due to the first bar magnet is inserted in pin-and-hole c, the bottom of the second bar magnet is inserted in pin-and-hole d, horizontal sliding can not be produced between lock dog and lock core, the head of lock dog is limited to the stopper slot of lock housing internal chamber wall simultaneously, so lock core can not be rotated, lockset can not be opened, the unlatching end face of key of correct pairing is only had to aim at the locating slot of plug face and after contacting with plug face, first bar magnet of lock core inside and the second bar magnet just can overcome the magnetic adsorptive power between lock dog and adsorbed by the first magnet of Keyed interior and the second magnet simultaneously and carry out upper mobile work, the bottom of the first bar magnet is all retracted in pin-and-hole a, the bottom of the second bar magnet is all retracted in pin-and-hole b, now rotate key more just can make to produce horizontal sliding between lock dog and lock core, the head of lock dog leaves stopper slot, so lock core could be rotated, so lockset is opened.If key is not right, the first magnet and the second magnet that do not mate arrangement carry out magnetic absorption to the first bar magnet and the second bar magnet simultaneously, lock core just can not be rotated, key is only had to mate completely with lock core, namely magnet and bar magnet are under prerequisite completely one to one, and lock core could be rotated opens lockset.
