Abstract

The utility model relates to a lock pin of a lockset applicable to a coaxial transfer type hidden key lock pin of anti-theft gates and anti-theft locks, comprising a lock body, a transfer lock pin, an unlocked lock pin and a key piece, wherein the transfer lock pin and the unlocked lock pin are coaxially provided and hidden in the lock body, only a running hand handle comes out, the key hole of the lock body is opposite to the key groove and the locked marble, the key hole of the lock body and the key groove are not in the same position. The shank of the key can be pushed on the key piece and glides up and down in the key seat, and the lodestone of the shank of the key front end is pushed to grip the key. When not in use, the key enters into the key seat as an integral body, when in use, the shank of the key pushes the key, and deviates from the key seat to transfer into the lock pin key groove. The utility model mainly provides the function that marble can not be stirred in the visible area before and after the opening, and solves the technical problems that the technical unlocking of the prior technique is easy to stir the marble.

Description

The coaxial latent key cylinder of formula that changes over to

Technical field

The utility model relates to a kind of lock core, is to be to be hidden in a kind of new type of opening in the lock body by the mode that changes over to about lock core key.

Background technology

Present lock core, accomplish real antitheft few, because of it all has its fatal weakness, pellet shot from a slingshot is all in the sight line that as seen can pull out, no matter be the atom lock, still press in, external-compression type atom lock all has in the category that pellet shot from a slingshot can pull out, the long slightly short slightly problem of only time faces the antitheft effect that loses equally.

Summary of the invention

In order to overcome the deficiency that existing key can not prevent skilled unlocking, the utility model mainly provides a kind of coaxial latent key cylinder of formula that changes over to, this coaxial latent key cylinder of formula that changes over to carries key in lock body by the method that changes key over to, the neat formation in pellet shot from a slingshot top unblanked, no matter under any circumstance all can't see pellet shot from a slingshot.Solve that prior art is existing extracts the characteristics that pellet shot from a slingshot is unblanked with technology.

Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of coaxial latent key cylinder of formula that changes over to, comprise lock body, change lock core over to, open lock core and key spare, the described lock core that changes over to is cylindric, open lock core annulus column, change lock core over to and be socketed in unlatching lock core annulus post the inside, last plane is concordant.The turning handle that changes lock core over to is less than changing the lock core cylinder over to, pass lock body and expose surface of lock body, be used for changing over to the outer side column of lock core and have key, with the keyhole alignment on the lock body, on unlatching lock core annulus post limit, have the pellet shot from a slingshot hole, pellet shot from a slingshot passes the unlatching lock core from lock body, enter and change in the lock core chute, form the lock shape, enter key, change the lock core turning handle over to when key passes lockhole, key is sent into pellet shot from a slingshot position in the lock body, the lock shape of grinding one's teeth that backs down pellet shot from a slingshot is in alignment, opens the lock core rotation thereby drive, and reaches unlocking function.Because key changes over to, change the back key in lock body the inside, form closed, also changed over to lock core below the lockhole originally to have a snack, a cutting tool is had no way of doing it.And before key does not insert, because keyhole key and pellet shot from a slingshot on two positions, so a cutting tool can't pull out pellet shot from a slingshot, thereby reach really antitheft.

Therefore, the coaxial latent key cylinder of formula that changes over to of the present utility model, by changing key over to, make pellet shot from a slingshot before and after opening not in visible position, have simple in structure, reasonable in design, the characteristics that can not open.

Description of drawings

Accompanying drawing 1 is the coaxial overall schematic that changes the latent key cylinder of formula over to of the present utility model;

Accompanying drawing 2 is coaxial vertical views that change the latent key cylinder of formula over to of the present utility model;

Accompanying drawing 3 is coaxial B-B sectional views that change the latent key cylinder Fig. 1 of formula over to of the present utility model;

Accompanying drawing 4 is coaxial key vertical views that change the latent key cylinder of formula over to of the present utility model;

Accompanying drawing 5 is coaxial key body schematic diagrames that change the latent key cylinder of formula over to of the present utility model.

The concrete example of implementing:

Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is further described in detail.

As shown in Figure 1.Coaxially change latent key cylinder over to and comprise lock body 1, change lock core 2 over to and open lock core 3 etc., changing lock core 2 over to and opening lock core 3 is coaxial settings, change lock core 2 over to for cylindric, it is circular opening lock core 3, change lock core 2 over to and be socketed in unlatching lock core 3 the insides, the cylinder that changing lock core 2 upper ends over to has and change over to lock core 2 to connect change over to lock core turning handle 10 pass lock body 1 expose the outside, be used to rotate and change over to lock core 2 cylindrical edges and axially have lockhole 4 alignment on key 5 and the lock body 1, open lock core 3 annulus post limits and be provided with pellet shot from a slingshot hole 8 when passing pellet shot from a slingshot 7, open lock core 3 and form the shape of grinding one's teeth, at this moment open lock core 3 and can not rotate.Enter key 5 when key 6 inserts lockholes 4, change lock core turning handle 10 over to when backing down 7 of pellets shot from a slingshot, unlatching lock core 3 can reach unlocking function with rotational lock core 2 rotations.Because when key 5 forwards pellet shot from a slingshot 7 positions to, change lock core 2 faces of cylinder over to and block lockhole 4, insert and do not advance anything, prevented technology unlocking.
