Abstract

The utility model discloses a mechanical cipher door lock, relating to the technical field of the door lock. The mechanical cipher door lock comprises a lock panel, a handle, and a lock cylinder. The lock panel is also provided with a cipher lock. The cipher lock comprises a cipher wheel, a lock hole, and a hinge lid. The cipher wheel is arranged on the lock panel. One side of the cipher wheel is provided with the lock hole. The hinge lid is connected with the lock panel via a hinge. The hinge lid is provided with a convex post which is matched with the lock hole. When the hinge lid is closed, the lock cylinder can be covered. The mechanical cipher door lock is not easy to be destroyed, and the antitheft performance is good.

Description

The mechanical cipher door lock

Affiliated technical field

The utility model relates to a kind of door lock, especially a kind of mechanical cipher door lock.

Background technology

At present, the mechanical door lock on the market mainly is made of lock panel, handle, lock core, and its weak point is that the outer end of the lock core of this lock directly is exposed, and lock core is injected glue by the people easily, cause lock core destroyed, and theftproof performance is bad.

Summary of the invention

In order to overcome the bad deficiency of existing mechanical door lock theftproof performance, the utility model provides a kind of mechanical cipher door lock, and the lock core of this mechanical cipher door lock is not easy destroyed, and theftproof performance is good.

The technical solution adopted in the utility model is, a kind of mechanical cipher door lock, comprise lock panel, handle, lock core, coded lock also is housed on the described lock panel, and described coded lock comprises cipher wheel, lockhole, renovates, and cipher wheel is arranged on the lock panel, cipher wheel one side is provided with lockhole, renovate and be connected through the hinge on lock panel, renovate and be provided with the projection that is complementary with lockhole, renovate when closing and lock core can be covered.

Because this mechanical cipher door lock comprises lock panel, handle, lock core, cipher wheel is arranged on the lock panel, and cipher wheel one side is provided with lockhole, renovates to be connected through the hinge on lock panel, renovates and is provided with the projection that is complementary with lockhole.When locking a door, earlier pin mechanical lock, make again that renovating closes covers lock core, the projection of renovating is inserted in the lockhole by lock core, the rotational password wheel pins projection again, renovates pinning thereby make, therefore, the lock core of this mechanical cipher door lock is renovated to be covered, and is not easy destroyedly, and theftproof performance is good.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the structure chart when closing renovated of embodiment mechanical cipher door lock.

Fig. 2 is the structure chart when opening renovated of embodiment mechanical cipher door lock.

The specific embodiment

As depicted in figs. 1 and 2, a kind of mechanical cipher door lock, comprise lock panel 1, handle 5, lock core 4, coded lock also is housed on the lock panel 1, and described coded lock comprises cipher wheel 2, lockhole 3, renovates 6, and cipher wheel 2 is arranged on the lock panel 1, cipher wheel 2 one sides are provided with lockhole 3, renovate 6 and be connected on the lock panel 1, renovate 6 and be provided with the projection 8 that is complementary with lockhole 3, renovate 6 and lock core 4 can be covered when closing by hinge 7.When locking a door, earlier key is inserted lock core 4, pin mechanical lock, make and renovate 6 and close lock core 4 is covered, the projection of renovating on 68 is inserted in the lockholes 3, rotational password wheel 2 pins projection 8 again, renovates 6 and pins thereby make.When unblanking, rotational password wheel 2 with projection 8 releases, will be renovated 6 again and open, and the core 4 that opens the lock with the key again just can have been unblanked.Lock core 4 outsides of this mechanical cipher door lock are many renovates 6 protection, and therefore, the lock core of this mechanical cipher door lock is not easy destroyed, and theftproof performance is good.
