Electronic insertion preventing device and lock body

Abstract

The invention discloses an electronic insertion preventing device and a lock body, which replace a mechanical insertion preventing structure of an electronic lock body in prior art and solve the technical problems of an action load of a locking tongue which is additionally increased in an indoor counter-locking security tongue, short service life and low reliability. The electronic insertion preventing device comprises an insertion preventing tongue component, a main locking tongue, a main locking tongue transmission device, a motor component, an oblique tongue component, an oblique tongue transmission block, a PCB and a locking body control module; the PCB is provided with a first photoelectric switch, a second photoelectric switch, a third photoelectric switch and a trigger switch, the first photoelectric switch and the second photoelectric switch are connected to the PCB and the main locking tongue, the third photoelectric switch is connected to the motor component, the trigger switch is connected to the insertion preventing tongue component, the main locking tongue transmission device is connected to the main locking tongue and the motor component, and the oblique tongue transmission block is connected to a square tongue transmission component; and the PCB is connected to the locking body control module, the lock body control module receives signals sent from the trigger switch, the first photoelectric switch and the second photoelectric switch, a command is sent according to signal contents, and the command is sent to a motor in a manner of current and the motor performs actions of forward rotation or backward rotation.

Description

technical field [0001] The invention relates to the field of electronic door locks, in particular to a lock body of an electronic door lock, an electronic anti-insertion device and the lock body. Background technique [0002] At present, all kinds of door locks and electronic door locks on the market have various functions. The locks are generally equipped with a combination bolt, a main bolt, a safety bolt, and some lock bodies are equipped with anti-insertion bolts. The main bolt is generally a large square bolt; when the door is closed, the oblique bolt assembly automatically extends out of the lock body, and the main bolt is locked by special locking actions such as keys, handles, etc., if you forget to perform the main bolt locking action when closing the door , when going out, only the latch bolt assembly completes the door locking action. At this time, a thin object such as a card is inserted into the door crack outside the door to try to retract the latch latch assem...
