Abstract
Description
Technical Field
[0001] This utility model belongs to the field of transmission technology, and specifically relates to a 180-degree transmission device. Background Technology
[0002] The transmission mechanism is mainly used to transmit the operating commands of the handle to the doors and windows, thereby realizing the opening and closing functions of the doors and windows.
[0003] The structure of the transmission device in the current technology is shown in this patent. CN203430228U discloses a push-pull transmission device for doors and windows, which includes a fixed plate, two wheel guards on the left and right, a sliding plate, an anti-pry pin and a gear as a whole. The fixed plate and the sliding plate are assembled in one wheel guard. The gear teeth are assembled on the rack of the sliding plate. The shaft of the gear end face is rotatably inserted into the rotating hole of the wheel guard. The other wheel guard is fastened to the assembled wheel guard. The shaft of the gear has a hole for installing a handle for operation. The anti-pry pin passes through the long sliding hole of the fixed plate and is riveted to the sliding plate. The anti-pry pin cooperates with the locking device on the door and window frame to lock or open the door and window.
[0004] One drawback is that, since the width and specifications of doors and windows vary greatly, the specifications of the actuator (such as the length specification) must be matched with the specifications of the doors and windows. That is, the lengths of the fixed plate and the sliding plate need to be matched with the dimensions of the doors and windows. Therefore, it is necessary to produce actuators of various specifications to meet the requirements, which increases production costs and is not convenient for production.
[0005] In addition, the limiting fork assembly in the existing structure is an independent component. The main function of the limiting fork assembly is to prevent the handle from being turned inward or to lock the window when the casement window is open, so as to improve safety. How to integrate the limiting fork assembly into the transmission to form a standard part with a safety structure is also one of our research and development directions. Utility Model Content
