The flat square of the guide rail penetrates through a flat round hole in the U-shaped support on the reverse side of the bolt fixing frame and then is fixed by a gasket and a screw I; the lower part of the bolt passes through the large waist-shaped hole in the middle of the decorative plate and can move up and down; the micro motor is arranged on the four fixing columns on the connecting plate, the four screw holes II are formed in the bottom of the micro motor, the gear is arranged on the end face of the micro motor, the screws II penetrate through the fixing columns to be connected with the screw holes II, the micro motor is fixed, and meanwhile the gear is meshed with the rack.

When the door is closed, the control system receives a signal, the micro motor rotates anticlockwise, and the door bolt is locked out; when the control system inputs correct password or fingerprint, the micro motor rotates clockwise, the door bolt retracts, and the door is opened.

The frame locking structure is fixed on the doorframe channel steel through six screws III to form a frame locking structure.

the door panel is fixed on a guide plate of the door panel through six screws, and replaces a transmission structure of the existing door.

The invention has the advantages that: the invention discloses an automatic telescopic door bolt, which is characterized in that a control panel controls a motor on the door bolt to rotate forwards and backwards to realize the opening and the locking of the door bolt. The inside grinding optical axis and the linear bearing transmission of adopting of keeper, it is light nimble, in the application, a plurality of keeper use in parallel, destroy any one or several of them at the thief, as long as have a keeper not open, the door just can not be opened, makes the thief have nothing from the beginning. The product has the advantages of simple design, low cost, convenient installation and use, and is especially safe and reliable.
