Description

Technical Field

[0001] This utility model relates to the field of door and window handle technology, specifically to a quick-install door and window handle. Background Technology

[0002] Door and window handles, typically installed on door and window locks, facilitate the opening and closing of doors and windows and are one of the most frequently used and important accessories in door and window products. Common door and window handles generally consist of a handle and a drive shaft. The drive shaft is fixed to the handle and works in conjunction with the transmission mechanism in the door and window lock. Rotation of the handle drives the transmission mechanism in the lock, controlling the movement of the bolt or locking pin to lock or open the door or window. However, currently available door and window handles have inconvenient connections between the handle and the drive shaft, making it difficult to quickly secure the drive shaft to the handle. The handle is prone to loosening after prolonged use, resulting in a poor user experience. Therefore, to avoid the shortcomings of existing technology, it is necessary to improve it. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings and deficiencies in the existing technology and provide a quick-install door and window handle with a simple structure and stable installation.

[0004] This utility model is achieved through the following technical solution:

[0005] A quick-install door and window handle includes a drive shaft, with a first handle and a second handle connected to both ends of the drive shaft. Each of the first and second handles is equipped with a metal connector. A fixing plastic part is installed on the inner side of the metal connector. The fixing plastic part has an opening for the drive shaft to pass through. A retaining strip is provided on the inner side of the fixing plastic part. Both ends of the drive shaft are provided with a plurality of slots corresponding to the retaining strip.

[0006] Furthermore, the metal connector is provided with a platform for mounting the fixed plastic part.

[0007] Furthermore, the end of the fixing plastic part is provided with a hook that abuts against the end of the metal connector.

[0008] Furthermore, the fixing plastic part is provided with an installation guide strip, and the metal connector is provided with an installation guide groove corresponding to the installation guide strip.

[0009] Furthermore, the metal connector is provided with a connecting post installed on the inside of the first handle or the inside of the second handle.

[0010] Furthermore, the inner side of the metal connector is provided with a through hole for the drive shaft to be fitted.

[0011] Furthermore, the metal connector is interference-fitted with the first handle and the metal connector is interference-fitted with the second handle.

[0012] Furthermore, the drive shaft is a square drive shaft.

[0013] Compared to existing technologies, this utility model features a fixed plastic component installed on the inner side of a metal connector. The fixed plastic component has an opening for the drive shaft to pass through, and a retaining strip is located on its inner side. Both ends of the drive shaft have several slots corresponding to the retaining strip. During installation, the metal connector is first fixed to the first and second handles respectively. The fixed plastic component is then installed onto the metal connector. Next, the drive shaft is inserted into the fixed plastic component in the first handle, where the retaining strip and slots are locked together to prevent the drive shaft from coming out. After the drive shaft is inserted into the door / window lock, it is then inserted into the fixed plastic component of the second handle, where the retaining strip and slots are locked together. This completes the installation of the door / window handle. The connection between the handle and the drive shaft is convenient and quick, ensuring the handle is securely fixed even after prolonged use, resulting in a better user experience.
