Said locking device I contains lock bolt, bracing frame, backing plate, and bracing frame and backing plate are all fixing on the wall, and it is arc that bracing frame is; An end face is respectively stretched out on both sides; On end face, be provided with screw, backing plate is arranged on the bracing frame bottom centre position, and lock bolt is spun on the center of bracing frame; The backing plate center is provided with one and is used for the groove that lock bolt is located, and the top of lock bolt is provided with annular knurl.
Said locking device II contains expansion bolt and ears locking nut, and expansion bolt is fixing on the wall, and the ears locking nut is used for the locking adjustment sheet is fixed on expansion bolt.
Said draw-in groove is made up of elongate slots and skewed slot, and said skewed slot is at least three, and said draw-in groove can have opening near the skewed slot at chain cylindrical void place.
The know-why that the utility model adopted is: when this anti-theft device is installed; Clip is locked on the door handle axle; Pass the hole on the clip with tightening bolt; Simultaneously chain is put on and is locked, can select the chain of different length according to actual conditions, guarantee door leaf open the distance be in the safe range.Because of the chain lower end is provided with locking adjustment sheet I, locking adjustment sheet I is a rectangle thin slice, and itself and chain link are provided with the chain cylindrical void, are used for the connection of chain, and the draw-in groove I of locking adjustment sheet I is inner at locking adjustment sheet I.Locking device I is installed on the wall, under the normal condition, separated attitude between locking adjustment sheet I and the locking device I; When the guest is visiting, needs to lock earlier adjustment sheet I and insert between the bracing frame and backing plate of locking device I, and regulate lock bolt; Make lock bolt pass draw-in groove I; And locking positioning is in the groove of backing plate, prevents that metope from destroying, and the groove that lock bolt is withstood on the backing plate is more firm.Through regulating locking adjustment sheet I, can regulate the relative position of lock bolt in draw-in groove I, with the distance of opening of control gate, as see that the stranger then keeps outside of the door, if it is visiting to run into relatives and friends, then will locks adjustment sheet I and take out, put the people and come in.
This anti-theft device also has other a kind of mounting means, and the profile of locking adjustment sheet II is consistent with locking adjustment sheet I, and difference is that draw-in groove II has opening near the skewed slot at chain cylindrical void place, and locking adjustment sheet II is more faster than locking adjustment sheet I.Locking device II is made up of expansion bolt and ears locking nut, and expansion bolt is fixing on the wall, and the draw-in groove II that locks adjustment sheet II is stuck in the expansion bolt, will lock adjustment sheet II locking with the ears locking nut.Through regulating locking adjustment sheet II, can regulate the relative position of expansion bolt in draw-in groove II, with the distance of opening of control gate, as see that the stranger then keeps outside of the door, if it is visiting to run into relatives and friends, then will locks adjustment sheet II and take out, put the people and come in.
The distance that above dual mode all can control gate be opened makes the householder can see messenger clearly, and the stranger can not be entered the room by force, is convenient to the transmission of article simultaneously again, has solved that the stranger swarms into indoor safety problem when opening the door, and plays the antitheft effect.
Beneficial effect of the present invention is: this anti-theft device is through regulating the relative position between locking adjustment sheet and the locking device, and the distance that the restriction door leaf is opened is to see the visitor clearly; Reach the purpose of transmitting article; Refuse stranger's entering simultaneously, all can lock anti-theft device night on daytime, plays prevention and do not have the effect of suffering from; The protection people life property safety has solved that the stranger rushes the indoor safety problem of people when opening the door.This anti-theft device security performance is good, simple in structure, easy to install.
