The utility model provides a technical scheme that above-mentioned technical problem adopted does: a door self-locking device for preventing burglary comprises a base, a sucker component and a first connecting rod, wherein a wedge block is integrally arranged at the front end of the base, an anti-slip layer is fixedly arranged on the lower end face of the wedge block of the base, the lower end of the first connecting rod is hinged with the base, a locking mechanism is arranged between the lower end of the first connecting rod and the base, the sucker component comprises a shell and a sucker, a second connecting rod is integrally arranged on the shell, the upper end of the first connecting rod is hinged with the second connecting rod, the vertical distance from the lower end of the first connecting rod and the hinge point of the base to the front end face of the wedge block is smaller than the vertical distance from the upper end of the first connecting rod and the hinge point of the second connecting rod to the end face of the sucker, the shell is provided with a sucker pulling mechanism.
Further, locking mechanical system include the locking lever, the locking lever include coaxial body coupling's big screw rod and little screw rod, the base on be provided with the mounting groove, the lower extreme of head rod insert the mounting groove in, the locking lever with the base the lower extreme level spiro union of head rod, wherein: the big screw rod is in threaded connection with the lower end of the first connecting rod, and the small screw rod is in threaded connection with the base.
Further, sucking disc pulling mechanism include pull rod and lock handle, the front end of pull rod with sucking disc fixed connection, the rear end of pull rod wear out backward the shell, the one end of lock handle with the rear end of pull rod articulated mutually, the articulated end of lock handle an organic whole be provided with the locking piece, work as the locking piece top the shell on, the pull rod by the backward pulling, the sucking disc AND gate between form the vacuum area, make the sucking disc adsorb on the door.
Furthermore, the first connecting rod is L-shaped.
Furthermore, the included angle of the bent part of the first connecting rod is larger than 90 degrees.
Compared with the prior art, the utility model has the advantages that the wedge block on the base of the device is plugged into the door crack, then the angle of the first connecting rod is adjusted, the sucking disc is attached to the door, then the sucking disc is adsorbed on the door through the sucking disc pulling mechanism, because the vertical distance between the lower end of the first connecting rod and the hinging point of the base and the front end surface of the wedge block is smaller than the vertical distance between the hinging point of the upper end of the first connecting rod and the second connecting rod and the end surface of the sucking disc, when a thief pushes the door from the outside, the thrust is applied to the upper end of the first connecting rod, so that the lower end of the first connecting rod generates a counter-thrust force towards the door direction, thereby forming a self-locking state, the door can not be opened, and the anti-theft effect is achieved; the wedge-shaped block is plugged into the door gap, so that the self-locking effect of the device can be further improved; in addition, the whole device is simple to disassemble and convenient to carry, and is also suitable for travelers to use.
