Abstract
The utility model discloses a theftproof door. A plurality of doors are arranged in a door frame, hinges are arranged between the door frame and one of the doors, and are arranged every two doors; a main lock is arranged on one of the doors, and other doors are respectively provided with a self-locking device. When the door is closed, along with the movement of the door, a diagonal cutting colliding lock tongue under the push of the other door rim causes a rack bar of a lock tongue to do a straight line movement. When the rack bar of the lock tongue is moved, and simultaneously a gear and a rotary disk with a connecting rod are driven by the rack bar of the lock tongue to rotate. The angle is changed because of the rotation of the rotary disk with the connecting rod, causing a connecting rod of the lock tongue arranged on the rotary disk with the connecting rod to elongate, and then a latch is locked by a lock bolt. Inversely, a lock is opened under the pulling action of a spring, and goals of the automatic locking and the automatic unlocking can be achieved without a key.
Description
The utility model relates to a kind of security door, especially a kind of can automatically locking and the collapsible security door of auto-unlocking.
At present, known security door has iron sliding door, rolling-gate, collapsible iron gate and single fan security door.Above-mentioned security door is because simple in structure, not only theftproof performance is poor, and application life is short, switch inconvenience, especially collapsible iron gate, because of the fixed method of last downside pin is to adopt skewer pin pin fixed, by manually-operated, theftproof extreme difference, the particularly door in some StoreFront doors and warehouse, still do not have at present desirable anti-theft device, bring hidden danger for the person and the safety of property.
The purpose of this utility model provides a kind of security door, and it is not only applicable to various StoreFronts and warehouse gate is installed, and has the collapsible security door of many fans that automatically locks with the auto-unlocking function.
The purpose of this utility model is achieved in that and is provided with multiple leaf door in doorframe, is provided with hinge between doorframe and door and the Men Yumen, and a main lock is housed on central Yishanmen, is provided with self-locking device on each at other.Described self-locking device is made of lock housing, connecting rod rotating disk, connecting rod, gear, dead bolt tooth bar, spring.At closing time, along with moving of door, Dou mouth collision dead bolt makes the dead bolt rack linear move under the promotion on another limit, driven gear and connecting rod dial rotation when the dead bolt tooth bar moves, owing to the rotation of connecting rod rotating disk conversion angle, the dead bolt connecting rod that is installed on the connecting rod rotating disk is extended thereupon, lock bolt is lived bolt, has reached self-locking purpose, otherwise, be opened owing under the effect that spring promotes, lock, need not key.On door, also be provided with burglary-resisting window.
Owing to adopt such scheme, the utility model has overcome the collapsible security door of many fans and need not key and just can automatically lock and unblank, and has advantages such as compact conformation, switch is convenient, theftproof is strong, durable in use.
The utility model is described in further detail below in conjunction with drawings and Examples.
