The utility model has the advantages of: the utility model discloses a mechanism of locking a door can lean on the automatic family of a general of mechanical transmission to close, and under the normal condition, then can rely on the manpower to open, close the door, and then make this locking mechanism's structure simpler relatively under the special condition, and manufacturing cost reduces, still be equipped with the leading wheel between the rack, through rotating to has the guide effect to the rack.
Description
Technical field
The utility model relates to a kind of door locking device, particularly the urgent lock door mechanism of one.
Background technology
Installing various forms of door, is all to provide a kind of sense of security to people.And the fast pace sense of existing life, make people have to quicken one's step.Like this, people will because of carelessness, and forget to lock a door sometimes, also just can not provide certain safety guarantee, and the loss of things is also just unavoidable, in order to make door have more the sense of security, have developed automatic lock door mechanism.
Current automatic lock door mechanism, it all realizes with motor when open and close door, and this not only compares power consumption, also needs often to change battery, causes not too environmental protection; In addition, motor is when rotating, and could produce the action shutting, unblank after also needing to be shifted, this provides guiding with regard to needing the movement of sliding shoe, slide post to the movement of motor, and therefore current automatic lock door mechanism more complicated, cost of production is higher.
For above-mentioned situation, be necessary that research and development are a kind of only in case of emergency, automatically door closed by machine driving, under normal circumstances, do not need the lock door mechanism by machine driving open and close door.Like this, cost of production can be made to reduce.
Utility model content
The technical problems to be solved in the utility model is to provide one can in a special case, automatically by urgent lock door mechanism that door is closed.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of urgent lock door mechanism, promptly lock for opposite house under special circumstances, its innovative point is: comprise connecting rod, gear, tooth bar and installing plate, one end of described connecting rod is hingedly fixed on the medial surface of door-plate, and the other end and gear are connected and fixed; The side of described gear be also provided with gear with the use of tooth bar, and this tooth bar be connected with one can make tooth bar away from or the driving mechanism of laminating gear; Meanwhile, be also provided with an installing plate in the same side of wheel and rack, this installing plate is a rectangular slab, and also has the cavity of an accommodation tooth bar activity in this installing plate.
Further, described tooth bar long axis direction has gathering sill, also installs a pair directive wheel through gathering sill on a mounting board, and installing plate is also provided with the limited block corresponding with directive wheel.
Further, described driving mechanism can be linear electric motors, also can be cylinder or oil cylinder.
Further, described tooth bar is also provided with down card.
The utility model has the advantage of:
(1) lock door mechanism of the present utility model, under special circumstances, driving mechanism just can drive tooth bar, thus driven gear rotates, and connecting rod is inwardly rotated, is closed by door; The lock door mechanism of this structure, can in emergency situations, close door by machine driving automatically, and under normal conditions, tooth bar away from gear, then can rely on manpower open and close door, and then making the structure of this retaining mechanism relatively simple, cost of production reduces;
(2) lock door mechanism of the present utility model, is also provided with directive wheel between tooth bar, by rotating, thus has guide effect to tooth bar, thus can be good at ensureing tooth bar do away from or the motion of laminating gear;
(3) lock door mechanism of the present utility model, driving mechanism can be linear electric motors, also can be cylinder or oil cylinder, specifically can carry out selection according to actual condition and install;
(4) by installing down card on tooth bar additional, when promptly locking a door, only can lock a door, can not open the door, during unblock, block releasing, can open the door.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the elevation of the utility model lock door mechanism.
Fig. 2 is the top view of the utility model lock door mechanism.
Detailed description of the invention
The following examples can make professional and technical personnel's comprehend the utility model, but are not therefore limited among described scope of embodiments by the utility model.
Embodiment
Lock door mechanism of the present utility model, forms by with lower part: connecting rod 5, gear 1, tooth bar 2 and installing plate 3.
As illustrated in fig. 1 and 2, one end of connecting rod 5 is hingedly fixed on the medial surface of door-plate, and the other end and gear 1 are connected and fixed; The side of gear 1 be also provided with gear with the use of tooth bar 2, and this tooth bar 2 be connected with one can make tooth bar away from or the driving mechanism 4 of laminating gear, the driving mechanism 4 of use be motor, and this driving mechanism 4 and tooth bar are bolted.
Meanwhile, be also provided with an installing plate 3 at gear 1 and the same side of tooth bar 2, this installing plate 3 is a rectangular slab, and also has the cavity of an accommodation tooth bar activity in this installing plate 3.
Have gathering sill at tooth bar 2 long axis direction, installing plate 3 is also installed a pair directive wheel 7 through gathering sill, and installing plate 3 is also provided with the limited block 6 corresponding with directive wheel.
Tooth bar 2 is also provided with down card, by the setting of falling to block, when promptly locking a door, only can locks a door, can not open the door, during unblock, block releasing, can open the door.
Operating principle: under normal circumstances, tooth bar 2 is away from gear 1, and when completing enabling, closing the door action, gear 1 freely rotates along with the effect of connecting rod 5; When running into special circumstances and needing promptly to lock a door, driving mechanism just can drive tooth bar 2 to move to gear 1 direction, can rotate by driven gear 1 simultaneously, connecting rod is inwardly rotated, and is closed by door, and by coordinating between tooth bar 2 with gear 1, ensures the locking of door.
The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and manual just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
