Antitheft door capable of preventing accidental closing

Abstract

The invention relates to an antitheft door capable of preventing accidental closing. The antitheft door comprises an antitheft door main body, a door lock mechanism, a handle, a handle shifting rod, a rotating spring and a reset mechanism, wherein the door lock mechanism, the handle, the handle shifting rod, the rotating spring and the reset mechanism are arranged on the antitheft door main body. The handle, the handle shifting rod and the rotating spring are arranged on the door lock mechanism and are connected into a whole. The handle shifting rod and the reset mechanism are connected in a shifted mode; a groove matched with the reset mechanism is formed in a door frame; when the handle is rotated, the handle pushes the handle shifting rod and enables the reset mechanism and the groove of the door frame to be tightly clamped; and when the handle is shifted again, the handle pushes the handle shifting rod and enables the reset mechanism to be disengaged from the groove of the door frame. The antitheft door is simple and reasonable in structure, and automatic closing of the antitheft door can be effectively prevented, so that the effect that a user is reminded to carry a key is achieved.
