Driving device

Abstract

The invention discloses a driving device. The driving device comprises a transmission mechanism, a lever handle and a locking mechanism. The transmission mechanism comprises an installation shell anda movable piece, a sliding groove is formed in the installation shell, and limiting edges are arranged at the tops of the two side walls of the sliding groove respectively. The movable piece is arranged in the sliding groove in a penetrating manner, and a transmission rack is arranged on the bottom wall of the movable piece. The lever handle comprises a handle body, a fixing base, a connecting shaft and a second fastener, a second mounting groove is formed in one end of the handle body, and an inner tooth part is arranged in the second mounting groove; the fixing base is arranged in the secondmounting groove and can be connected with a profile part; the connecting shaft is rotationally arranged in the fixing base and comprises a first outer tooth part and a second outer tooth part, the first outer tooth part is meshed with the inner tooth part, and the second outer tooth part can be meshed with the transmission rack; one end of the second fastener is connected with the bottom wall ofthe second mounting groove; and the locking mechanism can be arranged in the mounting shell and the mounting wall in a penetrating manner and is connected with the fixing base. The driving device hasa small installation space.

Description

technical field [0001] The invention relates to the technical field of doors and windows, in particular to a driving device. Background technique [0002] The door and window driving structure usually includes a transmission mechanism and a handle, and the movement of the transmission mechanism is driven by the handle to realize the overall transmission of the door and window hardware. In the prior art, a polygonal shaft is often provided on the output end of the handle, and a polygonal groove cooperating with the polygonal shaft is provided on the transmission mechanism that the handle cooperates with. The rotational force of the polygonal shaft can be transmitted to the transmission mechanism by operating the handle rotation, thereby The transmission mechanism can drive the hardware transmission in the door and window device to open and lock. In the process involved, the transmission mechanism not only needs to meet the specified stroke, but also needs to ensure the force...

AI Technical Summary

Problems solved by technology

In the process involved, the transmission mechanism not only needs to meet the specified stroke, but also needs to ensure the force of the square shaft hole. Therefore, the transmission mechanism in the prior art usually has a relatively large size to meet the above requirements, which makes the space occupied by the transmission mechanism too large. , when installing on the profile parts, the profile parts must be milled to meet the installation requirements, and the transmission parts must also be cut off to be installed at both ends of the transmission mechanism, which will not only destroy the cavity of the profile parts, but also greatly increase the processing of the transmission mechanism time

The handle formed according to the above transmission method usually requires a large installation space, and the installation of the handle on the profile is relatively cumbersome

At the same time, the rack and pinion of the door and window drive structure, the gear and the handle cooperate, so that the drive structure of the door and window has too many accessories, which is not only inconvenient to install, but also difficult to control the clearance of internal components
