Abstract
The utility model relates to an automatic door-lock without skew bolt. The essential technical proposal of the utility model is that a braking piece is provided with a lock limiting slide groove and a the slide groove of a shifting column; a torsion spring is connected between the shifting column which is fixed on a shifting slice and the spacing pin which is fixed on a lock casing; a set of pushing rod with spacing springs are arranged in the lock casing on the side face of the lock casing the moving direction of the braking piece; the contacts of the lock casing are arranged on the same side of a lock beam and extend out of the lock casing; a set of spacing rotor plate on the spacing pin are movably connected to the pushing rods; a bulge which can be used to limit the braking piece or the shifting slice is arranged on the pushing rods; a corresponding concave pit is opened on the braking piece or the shifting slice. The utility model has the advantages of flexible use, convenient use, simple structure and high safety.
Description
The utility model belongs to a kind of lock technology field, specifically a kind of automatic door lock that does not have oblique tongue.
Two flapper locks of selling in the market or single flapper lock, its kind is single, form of structure is traditional mode, tends to occur following phenomenon when using this lock: go out to work, shut the door after you in last class hour as people, and must take out key and door lock be locked again.Because the anti-poor performance of dialling of the oblique tongue of existing lock is worried when people go out, therefore need on the basis that skew bolt lock is called, with key door lock to be locked again.So just increase trouble, wasted the time to people.The pupil of family forgets easily with key and locks a door or lock bad door in addition, therefore also often brings worry and worry to the adult.
The purpose of this utility model provides a kind of no oblique tongue automatic door lock of locking automatically without key at closing time.
The purpose of this utility model is achieved in that it includes tapered end, keeper, lock housing, dead bolt, the stopper sheet, manual handle, plectrum, reversed column, the cover plate plectrum, it is characterized in that on the stopper sheet, having limit pin runner and reversed column chute, be fixed on the reversed column on the plectrum and be fixed between the spacer pin on the lock housing and be connected with a torsion spring, one touching lever that is with limit spring is set along the side of stopper sheet trend in lock housing, the contact of touching lever is at the homonymy of lock bridge and lean out lock housing, at the spacing rotor that is enclosed within on the spacer pin that is connected with alive on the touching lever, having one on spacing rotor can spacing stopper sheet or the projection of plectrum, and has corresponding pit at stopper sheet or sliding piece.When the touching lever contact on the lock housing is subjected to collision compression in shell when mobile, then spacing rotor will be that axle rotates with the spacer pin, when spacing rotor turns to certain angle, projection on the pit of stopper sheet or sliding piece and the spacing rotor is thrown off, and then the stopper sheet drives the just ejection automatically of square dead bolt by reversed column under the effect of torsion spring; When opening the door, the projection on the rotation manual handle (indoor) or drive reversed column by key turns cover plate plectrum and lock is opened (outdoor), this moment spacing rotor is got back to again in the pit of stopper sheet or sliding piece.
The utlity model has following advantage:
(1), use flexiblely, square dead bolt can eject automatically, saves time, and all is applicable to inward and outward opening door.
(2), simple in structure, have only stopper sheet, spacing rotor, stopper sheet plectrum and touching lever, realize whole actions by torsion spring.
(3), safe and reliable, if pull manual toggle, then stopper sheet reversed column is by manual toggle fore-set, the then outdoor human key door of also not opening; Do not needing at closing time, also can pull manual toggle, even shut the door like this, dead bolt can not stretch out, and avoid shutting with the handgrip door.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a Facad structure schematic diagram of the present utility model.
Fig. 2 is that the A-A of Fig. 1 is to side sectional view.
Fig. 3 is the structural representation of the utility model locking state.
Fig. 4 is the structural representation of the utility model door opening state.
Shown in Fig. 1-4,1 for being fixed on the pin button box on the doorframe, 2 is lock housing, 3 is manual toggle, 4 is manual handle, in lock housing 2, be equipped with dead bolt 8 and stopper sheet 9, on the stopper sheet, have spacer pin chute and reversed column chute, be fixed on the plectrum 7 reversed column 6 be fixed on lock housing on spacer pin 5 between be connected by torsion spring 10, in lock housing with stopper sheet and the dead bolt touching lever 12 that is with limit spring 15 that be arranged in parallel, the contact of touching lever is at the homonymy of lock bridge and lean out lock housing, and the axis of contact on the touching lever and dead bolt increases on the face at same water.Be with a spacing rotor 11 on spacer pin, this spacing rotor is lived with touching lever and is connected.On spacing rotor, have folding fin 13 at an angle of 90, and on the spacer pin chute, have a pit.When (see figure 3) at closing time, the touching lever contact that leans out lock housing is compressed by collision, touching lever is moved in shell, to with spacer pin be that axle rotate with the touching lever spacing rotor that is connected alive this moment, when turning to certain angle, the fin on the spacing rotor breaks away from the pit on the spacer pin chute, and reversed column rotates under the effect of torsion spring, and promote the stopper sheet dead bolt is ejected, dial this this moment and forward " extremely " to by torsion spring and put position (promptly being the position of locking of dead bolt).If it is spacing with reversed column to pull manual toggle again, then make this lock locked, then the human key door of also not opening in the outside.(see figure 4) when opening the door, key is stirred cover plate plectrum 14 and drive reversed column, make the withdrawal of stopper sheet, when the complete return of dead bolt, in the following again pit to chute of the fin on the spacing rotor, promptly door is opened, if pull manual toggle again, even if touching lever is stressed, dead bolt can not eject yet, avoid the people to shut the door after you, and left behind the situation that key is locked out the people.
Claims (3)
1, a kind of no oblique tongue automatic door lock, it includes tapered end, keeper, lock housing, dead bolt, the stopper sheet, manual handle, plectrum, reversed column, the cover plate plectrum, it is characterized in that on the stopper sheet, having limit pin runner and reversed column chute, be fixed on the reversed column on the plectrum and be fixed between the spacer pin on the lock housing and be connected with a torsion spring, one touching lever that is with limit spring is set along the side of stopper sheet trend in lock housing, the contact of touching lever is at the homonymy of lock bridge and lean out lock housing, at the spacing rotor that is enclosed within on the spacer pin that is connected with alive on the touching lever, having one on spacing rotor can spacing stopper sheet or the projection of plectrum, and ground stopper sheet or sliding piece have corresponding pit.
