Background technology

The applying date is 2001.5.25, and the patent No. is 01235164.4, and name is called the patent of quiet electric control lock, has following drawback: the one, and lasting electronic delay circuit, complex structure, the cost height of adopting of opening time of unblanking of switching on; The 2nd, locking device movable part-snap close and scotch are installed between plastics seat board and the cover plate, the gap is too little between snap close and scotch and plastics seat board and the cover plate, under northern sandstorm environment, use, the gap is stopped up by dust easily and is caused snap close and scotch malfunctioning, it is unreliable to work, and applicable surface is narrow; The 3rd, snap close and scotch return spring adopt tongue and helical spring respectively, and elastic force is little, and return is unreliable; The 4th, locking device is connected with lock housing with three screws, and wherein the bottom connects inconvenience for one piece, and installation efficiency is low.

Summary of the invention

The purpose of this utility model is to provide a kind of simple and easy reliable quiet electric control lock that can overcome above-mentioned drawback.

This lock comprises lock body, locking bolt, locking bolt seat and lock core; Lock body comprises locking device, opening device, unlatching time-delay mechanism and lock housing; Opening device comprises electromagnetic coil, shoulders bar, the lock core shifting block, shoulder bar shifting block, spring;

Locking device comprises seat board, snap close axle, scotch axle, torsion spring, snap close, scotch and cover plate; There are 90 degree crimpings in the seat board outside, and jagged on the crimping, there is pin the seat board inboard, pin is inserted in the lock housing jack, and arc-shaped slot is arranged in the seat board, and snap close axle and scotch axle are 3 grades of cylinders, its diameter foot is greater than the middle part, the middle part is installed on the seat board greater than the end, and torsion spring is installed in snap close axle and scotch axle bottom, the middle part is installed snap close and scotch respectively, cover plate is installed in the end, and the side edge thereof gear shaping is inserted on the seat board crimping in the breach, and two of snap close torsion springs stretch out the line hook; Article one, be hooked on the snap close pin, another hook strips in base plate hole, snap close pinning and pinning inject respectively in the arc-shaped slot and arc-shaped slot in, two of scotch torsion springs stretch out the line hook, article one, be hooked on the scotch pin, another is hooked in the arc-shaped slot, and pin injects in the arc-shaped slot; Seat board is a steel plate;

The unlatching time-delay mechanism is a mechanical type, and it comprises time-delay fork, spring and axle; Axle is installed on the position, the upper right corner, seat board outside, time-delay fork upper end shaft hole sleeve is contained on the axle, there is a step at time-delay fork middle part, during the time-delay state, step holds up and shoulders bar, and during locking state, step withdraws from shoulders bar, spring one end hook is on time-delay fork lower end, and the other end is hooked on the snap close pinning external part.

Time-delay principle: when electromagnetic coil is switched on, shoulder the bar right-hand member and descended by magnetic, left end rises, and the scotch pin is held up, this moment, locking bolt was also in the pin button, the time-delay fork moves to left under the spring tension effect, and its step holder and shouldered the bar left end, after the outage, make lock still be in opening, arrive until the people that opens the door, pull the door open, locking bolt withdraws from lock body, the pin button just is in opening, under the pushing of snap close pin, the time-delay fork moves to right, and step is no longer holding in the palm shoulders the bar left part, the left part is moved down, after the people that opens the door enters door is shut, locking bolt enters in the snap close, and lock is in locking state again; Click electric switch, energising only is in a flash, is the Men Lakai required time delay time from the back that cuts off the power supply to the people that opens the door, and makes lock be in opening by time-delay mechanism entirely in delay time.

The utility model characteristics: the one, this lock opening time continues, and adopts the mechanical type time-delay mechanism, and simple structure is easy to manufacture, cheap; The 2nd, the locking device seat board adopts steel plate, and the gap is big between snap close and scotch and the seat board, can not stopped up by dust, and reliable operation, widely applicable; The 3rd, snap close and scotch return spring adopt torsion spring, and elastic force is big, and return is reliable; The 4th,, easy for installation at the bottom of locking device seat board and the lock housing with pegging graft, the installation efficiency height.
