Improved transmission of bidirectional lockset of door and window

Abstract

The invention discloses a transmitter of bidirectional window lock, comprising a frame, a driving gear, a first driving bar, a second driving bar and a track plate. The firs driving bar is integrated with a first tooth bar. The second driving bar is integrated with the second tooth bar. The first and second tooth bars are parallel arranged under the diving gear, while the tooth of driving gear ismeshed with the tooth of first tooth bar. A steering transmission gear is arranged between the driving gear and the second gear. The steering transmission gear is axially mounted on the frame, while its tooth is meshed with the tooth of second tooth bar and the driving gear. The invention can improve the structural stability and improve the anti-torsion ability to 6Nm, to prolong the service lifeof lock.

Description

An improved driver for two-way door and window locks technical field The invention relates to a door and window lock, in particular to an improved driver of a two-way door and window lock. Background technique The transmission device of existing door and window lockset comprises two housings, and is provided with large and small engaging seat and solid bolt lever etc. on housing, drives gear, driving bar and rail piece etc. in housing. Chinese Utility Model Patent No. 03280006.1 discloses a door and window lock capable of two-way locking. The drive includes two driving bars, the teeth of the driving gear correspond to the teeth of one of the driving bars, and the driving gear is driven by the rotation of the driving gear. The drive bar moves, and a transmission gear is set between the two drive bars, so that the movement of one of the drive bars drives the other drive bar to move in the opposite direction; there is also a protrusion on the drive bar, which is connected to ...

AI Technical Summary

Problems solved by technology

But such a structure only drives one driving bar to move because the driving gear, the direct force of the driving bar and the driving gear is only one of the driving bars, and the other driving bar is through the transmission gear arranged between the two driving bars. The transmission can move, and the transmission gear is only embedded between the two driving bars, without a proper fixed force point. The internal torsion resistance of the lock with this structure is not strong. When the lock is used for a long time, due to the increase of friction, it is easy to cause It cannot be locked or opened. If it is locked or opened vigorously, it will easily damage the lock and greatly reduce the service life of the lock.
