Description

Built-in handle of safe

Technical Field

The utility model relates to a safe handle capable of hiding an operation knob.

Background

The handle body of the handle used by the traditional safe door directly extends out of the door plate for a larger distance no matter what state, namely the handle body always exceeds the door surface. In the transportation process of the safe door with the outward-extending handle, the handle body is always exposed, so that the handle is easily damaged by external collision, the appearance of the handle is damaged, and the handle shaft can be seriously broken or deformed, so that the handle integrally loses the use performance, and the normal opening of the safe box is influenced.

In view of the above situation, a telescopic handle mechanism has been invented, which can hide the handle body in the recess of the door panel, so that the outer surface of the handle body is flush with the outer end surface of the door panel, thereby ensuring that the handle is not damaged by external collision during transportation, and preventing a lawbreaker from forcibly rotating the handle to damage the driving mechanism and the lock mechanism in the safe without knowing a password or a key.

The telescopic handle mechanism for the safe box, as well as the adjustable telescopic panel lock, as disclosed in the chinese utility model patent with patent number ZL200720191731.4 (publication number CN201125597Y) and the chinese utility model patent with patent number ZL200820085173.8 (publication number CN201176755Y), all disclose a safe box door with a telescopic handle, which is retracted into the safe door under normal state and is only ejected when opened.

The prior telescopic handle mechanism has the following defects: the clutch mechanism is arranged between the handle shaft in the handle and the driving mechanism, namely, the handle shaft is separated from the driving mechanism under the state that the head of the handle is retracted into the door plate, the handle idles, and the handle shaft is connected with the driving mechanism under the state that the head of the handle extends out of the door plate.
