Problems solved by technology

However, the structure in the application for this invention has solved the problem that the transmission gear is only embedded between the two drive bars and there is no proper fixed stress point in the previous transmission, so that the internal structure of the transmission is not strong in torsion resistance and is easily damaged.
However, one end of the transmission gear fixing piece is fixed to the central axis of the reversing transmission gear, and the other end is fixed on the housing, so that when the reversing transmission gear rotates, the fixing force of the transmission gear fixing piece to the reversing transmission gear is uneven. , Long-term use is prone to loosening of the drive gear fixing piece, and the phenomenon of not firmly fixing the reversing drive gear. In addition, the current two-way drive is not very convenient to install during installation.

Abstract

The invention discloses a bidirectional driver for a lock of a door or a window, which comprises a shell; the two sides of the shell are provided with fixing holes in which fixed governing mechanisms are arranged; the interior of the shell is provided with a drive gear, a first drive strip, a reverse drive gear, a drive gear bearing strip and a second drive strip; one end of the central shaft of the reverse drive gear is connected with the shell in coupling, and the drive gear bearing strip is provided with a middle hole and two end holes; the other end of the central shaft of the reverse drive gear is connected in the middle hole of the drive gear bearing strip in coupling; the two end holes of the drive gear bearing strip are socket-jointed with a pin piston integrated with the shell, in this way, the drive gear bearing strip fixes the rotation of the reverse drive gear in two directions; when the reverse drive gear is rotated, the fixing force of the drive gear bearing strip exerted to the reverse drive gear is more uniform, which overcomes the phenomenon that the drive gear bearing strip of a driver is easy to generate looseness when being used for a long time, thus prolonging the service life of the bidirectional driver.

Description

technical field [0001] The invention relates to a door and window lock, in particular to a bidirectional driver of the door and window lock. Background technique [0002] The driver of the door and window lockset is used to lock or open the doors and windows. Its structure includes a housing, a driving gear, two driving racks, a reversing transmission gear and a track piece, etc. For example, the Chinese patent application number of the inventor is 200710066915.2 Just disclosed the invention patent application of "an improved transmission for two-way door and window locks", its structure includes a housing, a driving gear, a first driving bar, a second driving bar and a track piece, the first driving bar is integrally provided with a second A rack, the second drive bar is integrally provided with a second rack, the first rack and the second rack are arranged under the drive gear in parallel, the teeth of the drive gear mesh with the teeth of the first rack, and the drive gea...
