Disclosure of Invention
The invention provides a combined impact-resistant protective door locking mechanism, which solves the problems that the traditional locking mechanism has heavy weight, can not realize local maintenance, needs to be integrally disassembled during maintenance, has long maintenance time and is difficult to replace parts. The impact wave can be better resisted to resist the forward and reverse pressure of the door leaf, so that the impact resistance and the protection performance of the protection door can be enhanced.
In order to solve the technical problem, the invention provides a combined impact-resistant protective door locking mechanism, which is characterized in that: the locking device comprises an upper locking part 1 and a lower locking part 2, wherein the upper locking part 1 and the lower locking part 2 are combined by a modular locking component; the modularized locking assembly comprises a motor 11, a motor seat 12, a main transmission rod 13, a rail seat 14 and a connecting rod mechanism 15, wherein the motor 11 is fixed on the protective door, the main transmission rod 13 is horizontally arranged on the protective door through the rail seat 14, and one end of the main transmission rod is connected with an output shaft of the motor; the main transmission rod 13 is connected with the fixed slide of the link mechanism 15.
Has the advantages that: compared with the traditional locking mechanism, the whole locking mechanism is heavy, local maintenance cannot be achieved, the locking mechanism needs to be integrally disassembled during maintenance, maintenance time is long, parts are difficult to replace and the like. The defect that an old locking mechanism still needs to be opened and closed by partial manpower is overcome, full-automatic opening and closing can be achieved on the premise of electric power guarantee, manual closing is not needed, and the function of a manual switch is still kept under the emergency or power-off condition. On the one hand, the anti-explosion, anti-impact and reverse impact capabilities of the side-hung protective door can be effectively enhanced, and on the other hand, modular parts can be independently disassembled, so that later-stage maintenance is facilitated.
