Description

The differentiated control mechanical lock

(1) technical field

The utility model relates to a kind of differentiated control mechanical lock, belongs to the daily necessities field.

(2) background technology

Often there are even more classrooms up to a hundred in present school, and the management of each classroom key has just been become to a pretty troublesome thing.School has to have a large amount of keys, search pretty troublesome, and easily lose, confusion.Have a holiday or vacation while regaining each class of key, but the key that private is joined is uncontrollable.Like this management in each classroom not only bothered, but also exist a lot of potential safety hazards.If use electronic lock as in large hotel, purchase cost is very high, and electronic lock also be unable to do without electricity, need the Special Equipment management, maintenance cost is high, and magnetic card key can not show a candle to again mechanical key and stablizes durable, easily damage, very dangerous concerning school, therefore be not suitable for school and use.

(3) summary of the invention

The utility model is in order to make up the defect of prior art, the differentiated control mechanical lock that a kind of cheap and durable is provided and has had the differentiated control function.

The utility model is achieved by the following technical solution:

A kind of differentiated control mechanical lock, comprise lock body and lock core, and the A hole of bead is set on lock body, it is characterized in that: described lock core inside evenly arranges seven row's locked grooves, and two-layer lock pearl is equipped with in every row's locked groove inside.

Wherein:

Described lock body upper end arranges the B hole of bead, and B plays in the hole of bead purpose of managing locks.

The utility model is realized by following operating principle: least privilege be according to the lock pearl key that two-layer total length is made separately, what highest weight was limit is the key of making according to lock pearl bottom length, between between the two, the perforation of doing according to bottom lock pearl numeral system has determined their authority, if such perforation position and quantity can comprise other key, its authority is just higher than involved person, if can not comprise mutually, their authority is with regard to equality, and this has just formed the differentiated control system.

Be provided with the A hole of bead and the B hole of bead on lock body and realized the locking of higher level's key to subordinate's key, insert from the A hole of bead when higher level's key part top layer lock pearl is headed into to the hole of bead, then turn core and lock door lock, from the B hole of bead, extract out again, lock pearl in upper strata has been stayed in the A hole of bead like this, thereby has changed the two-layer total length of these lock pearls.And these perforations of subordinate's key are to make according to the total length of two-layer lock pearl, the total length that higher level's key has changed the lock pearl just makes subordinate's key lose efficacy, thereby opened lock has more also just been realized the locking of higher level's key to subordinate's key.Again insert higher level's key, will turn core and rotate back into A hole of bead place again and extract out, upper strata lock pearl gets back to again and turns in-core, with lower floor lock pearl can and, the total length of two-layer lock pearl recovers former state, and subordinate's key can continue again to use, and this has just realized the release of higher level's key to subordinate's key.

The beneficial effects of the utility model are: compact conformation, and easy to use; Durable, failure rate is low, easy to utilize; There is the differentiated control function of electronic lock, facilitated people's management.

(4) accompanying drawing explanation

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

Accompanying drawing 1 is the utility model differentiated control mechanical lock structure schematic diagram;

Accompanying drawing 2 is the lock core structure schematic diagram.

In figure: 1, lock body; 2, lock core; 3, the A hole of bead; 4, locked groove; 5, lock pearl; 6, the B hole of bead.

The specific embodiment

Accompanying drawing is specific embodiment of the utility model.

The utility model differentiated control mechanical lock as shown in Figure 1, comprise lock body 1 and lock core 2, and the A hole of bead 3 is set on lock body 1, and described lock core 2 inside evenly arrange seven row's locked grooves 4, and two-layer lock pearl 5 is equipped with in every row's locked groove 4 inside, and lock body 1 upper end arranges the B hole of bead 6.

When higher level's key, from the A hole of bead, 3 insertions head into the hole of bead by part top layer lock pearl 5, and then turn core and lock door lock, then 6 extractions from the B hole of bead, lock pearl 5 in upper strata has been stayed in the A hole of bead 3 like this, thereby has changed the two-layer total length of these lock pearls 5.And these perforations of subordinate's key are to make according to the total length of two-layer lock pearl 5, the total length that higher level's key has changed lock pearl 5 just makes subordinate's key lose efficacy, thereby opened lock has more also just been realized the locking of higher level's key to subordinate's key.Again insert higher level's key, will turn core and rotate back into 3 places, the A hole of bead again and extract out, upper strata lock pearl 5 gets back to again and turns in-core, with lower floor lock pearl 5 can and, the total length of two-layer lock pearl 5 recovers former state, and subordinate's key can continue again to use, and this has just realized the release of higher level's key to subordinate's key.

Claims (2)

1. a differentiated control mechanical lock, comprise lock body (1) and lock core (2), the A hole of bead (3) is set on lock body (1), it is characterized in that: described lock core (2) inside evenly arranges seven row's locked grooves (4), and two-layer lock pearl (5) is equipped with in every row's locked groove (4) inside.

2. differentiated control mechanical lock according to claim 1, is characterized in that described lock body (1) upper end arranges the B hole of bead (6).
