Abstract

The invention is an electric machine lock, comprising lock body, lock latch, lock tongue, key, knob and micromotor, where the lock body is composed of main casing and cover, the knob passes through the cover and the shaft of the knob extends into the lock body, and it is driven by the micromotor, a small gear drives a large gear, a pull rod rotating shaft drives a link rod, the link rod drives the lock tongue back, a fastening plate is inserted into a special-set groove on a rotating disc under the action of a pagoda spring to fasten the rotating disc so as to achieve the door-opening purpose; a magnetic steel A is fastened in the step inner hole of the push rod, a magnetic steel B is fixed in the lock latch to be opposite to the center of the magnetic steel A and the same polarities are opposite, and under the action of repulsive force, the push rod is driven to trigger the fastening plate to shrink the pagoda spring; the fastening plate is drawn out from the special-set groove and the door is automatically locked under the action of torsional spring. Whether the power is cutoff or not, closing the door can implement automatic locking of the door, and the lock tongue can not be drawn out, manually or electrically.

Description

1. Technical field [0001] The invention relates to the field of locks, in particular to a motor lock which uses a micro-motor to open and close the lock. 2. Background technology [0002] Existing motor locks all adopt reed switches and circuit boards to control motors, such as a "new motor lock" disclosed by a Chinese patent (ZL02259181.8, date of announcement: 2003.12.10), which includes a main lock body and a secondary lock body that is Lock buckle, lock head assembly and three-eye plate, key, knob, control circuit board and electronic control circuit, micro-motor, the main lock body is composed of the main lock shell and the main lock cover, and the knob passes through the main lock cover and its shaft extends into The main lock body is equipped with a micro-motor and a control circuit board. The electronic control circuit controls the positive and negative rotation of the micro-motor. It is characterized in that the positive and negative rotati...
