Problems solved by technology

[0003] As a kind of architectural hardware accessories, most of the traditional door and window transmission locks use screws to fix the transmission main board, guide rail and transmission rack, which is inconvenient to install and operate. When the handle is installed, tightening the screws with a little force will easily cause the transmission main board to tilt, which will increase the locking force of the lock to varying degrees, resulting in unsmooth transmission and affecting the assembly accuracy and use effect of the lock.
In addition, the transmission main board of the traditional door and window transmission lock is mostly spliced ​​by multiple panels. There are obvious splicing seams on the transmission main board. At the same time, there are mounting holes at the screw installation, and the screws are exposed, which affects the appearance.

Abstract

The invention discloses a door and window transmission locking device. A transmission gear is mounted in a locking box of the locking device. Two locking blocks are movably mounted on the locking box.Each locking block comprises a swivel nut and a positioning block, wherein a threaded hole is formed in the swivel nut, and the positioning block is arranged at one side of the swivel nut in a connected mode. First mounting holes and second mounting holes are formed in the locking box. The first mounting holes penetrate through the locking box in the thickness direction, and the second mounting holes are formed in the side wall of one side of the locking box. The swivel nuts are movably mounted in the first mounting holes correspondingly, and the positioning blocks are movably mounted in thesecond mounting holes correspondingly. A plurality of flanges arranged in the length direction of the locking box are arranged integrally on the side wall of the other side of the locking box and flush with the upper surfaces of the two positioning blocks. The heights of the positioning blocks and the flanges adapt to the heights of standard C-shaped slots in an European standard aluminum alloy window sash profile. By means of the locking device, mounting can be fast, firm and reliable, the force for fixing a handle is increased, and the assembling precision, transmission effect and using effect of the locking device are improved.

Description

technical field [0001] The invention relates to a building hardware door and window fitting, in particular to a door and window transmission locker. Background technique [0002] The structure of the door and window transmission lock usually includes a lock box and a transmission main board. On one side of the transmission main board, a guide rail and a transmission rack are fixed by screws. The transmission rack meshes with the transmission gear installed in the lock box, and the lock box is installed on the guide rail. superior. After assembly, fix the lock box so that the transmission gear is connected with the handle. When the handle is turned, the transmission gear rotates, driving the transmission rack, guide rail and transmission main board to move as a whole, and then realizes the locking and opening of the door and window. [0003] As a kind of architectural hardware accessories, most of the traditional door and window transmission locks use screws to fix the trans...
