portable safe

technical field

The utility model relates to the technical field of safes, in particular to a portable safe.

Background technique

Safe is a special container, according to its function is mainly divided into fire safe and theftproof safe, antimagnetic safe, fire antimagnetic safe and the fire antimagnetic safe and so on. Safes can be divided into mechanical safes and electronic safes. Mechanical safes are more reliable in performance, but inconvenient to open, while electronic safes are easy to use. The handling and carrying of some valuables require insurance, so the current safes are gradually becoming smaller and easier to carry; Occupying the space of the safe, if the parts are scaled down, it will be difficult to process and manufacture, and because the small safe is easy to carry, the limit of some locks and lock cylinders is unstable after being connected, and the safe can be opened by dropping or knocking. The locking mechanism of the common small safes at present is too simple, lacks self-locking function, poor safety performance and easy to be opened.

Chinese patent authorization announcement number: CN20392511U, authorized announcement date on November 5, 2014, discloses a small safe door lock anti-gravity self-locking structure, which is a cam mechanism, and is installed on the inner side of the safe door corresponding to the rotating handle at the outer end of the safe , the cam mechanism includes a cam, a follower and a frame. The cam is hard-connected to the rotating handle at the outer end of the safe, and can rotate with the rotating handle. The moment balance of the cam will not rotate without external force, including the lower surface contour and the upper limit. side protrusions, the position-limiting side protrusions cooperate with the follower to limit the position, and the follower is arranged on the frame. Its shortcoming is that this kind of safe door lock is easily opened after locking, and it is inconvenient to use.
