Abstract

The invention belongs to the technical field of accessories for building doors and windows and particularly relates to a transmission locking device for a casement window. The transmission locking device for the casement window is characterized by comprising a transmission rod, a gear is installed on the transmission rod in a matched mode, two sides of the gear are provided with a location column respectively, the location columns are respectively installed on a protective jacket and a wheel protective plate, and the gear, the location columns and the protective jacket are installed in the wheel protective plate in a sleeved mode and riveted together. The transmission locking device has the advantages of being reasonable in structural design, convenient to install and use, small in window opening and closing force, reasonable and accurate in material selection, strong in corrosion resistance, wide in application scope and the like. The transmission locking device can use a square-shaft type handle and meets demands of popularization and application of the casement window and daily life of people.

Description

(1) Technical field [0001] The invention belongs to the technical field of accessories for building doors and windows, in particular to a transmission locker for casement windows. (2) Background technology [0002] Casement windows have been widely promoted and applied in my country due to their excellent thermal insulation, air tightness, water tightness, wind pressure resistance and air sound insulation performance, and have played an important role in the construction of our country and the improvement of people's living environment quality. It played its due role, and also made a great contribution to the energy saving and consumption reduction of public and civil buildings in my country (especially the saving of heating energy consumption and air conditioning energy consumption). With the deepening of building energy-saving work and the advancement of the 75% index of building energy-saving implementation, the door and window technology is constantly improving an...
