Description

A kind of backset structure of rotating latch door lock

Technical field

The present invention is a kind of door latch structure, particularly relates to a kind of backset structure of rotating latch structure door lock.

Background technology

As everyone knows, prior art comprises number of patent application 200910053634.2, and the door latch structure of name of patent application multinomial technical schemes such as " a kind of the door latch structures that the preloading state is opened down " is to be cooperated with backset by snap close to constitute; Snap close is the rotation long slab of evagination one fritter seaming; Backset is one section cylindrical bar, and cylindrical bar is half the along its length to be breach, and promptly the cross section is a semicircle; Half the is the face of cylinder, and promptly the cross section is circle.When the seaming of snap close is positioned at indentation, there, snap close is unobstructed can to rotarily open door leaf, and when the face of cylinder of stopper is positioned at the seaming place of snap close, the seaming of snap close is stopped that by the face of cylinder snap close can't rotate, and door leaf can't be opened.

Said backset is one section cylindrical bar, and half the is breach, and half the is the face of cylinder; Cylindrical bar is that front-rear reciprocation movement makes the breach of backset when needs open the door, promote to move to snap close seaming bottom vertically, when needs close latching door, promotes backset and moves; Make the face of cylinder section of backset be positioned at the seaming bottom of snap close; Moving axially by electromagnetic solenoid control of backset, when the electromagnetic coil energising or the outage generation magnetic flux of electromagnetic solenoid, the electromagnet in the middle of ordering about moves back and forth.
