A profile door lock handle assembly

Abstract

The invention discloses a profile door lock handle assembly and aims to provide a profile door lock handle assembly with simple structure, low installation requirements, convenient use, small opening torque, high safety performance and long service life. The profile door lock handle assembly includes a handle body, a square bolt connected to the handle body, and a fixing seat sleeved on the handle body, and the fixing seat is rotatably matched with the handle body through a bearing device. The bearing device includes sliding bearings and ball bearings arranged sequentially from the inside to the outside, the sliding bearings are sleeved on the handle body, the inner ring of the ball bearings is sleeved on the sliding bearings and connected to the Compatible with sliding bearings. The invention can be widely used in the field of profile doors.

Description

technical field [0001] The invention relates to a profile door lock handle assembly. Background technique [0002] A door lock is a device used to lock the door to prevent others from opening the door. This device may be mechanical or electric, and electric power requires electric energy. Due to different lock making technologies and applications, the door locks are divided into the following categories: 1. Spherical door locks; 2. Three-bar handle locks; 3. Mortise handle locks; 4. Glass door locks. The above three types of door locks are all used for existing profile doors. In order to improve the smoother opening of the door, thereby improving the quality and life of the lock, bearings are installed in the existing door lock handle components, but due to some profiles The thickness of the door is relatively thin, and the door leaf is prone to deformation during the installation of the handle, which will cause the door lock to be stuck and the handle cannot be reset norma...

Problems solved by technology

The above three types of door locks are all used for existing profile doors. In order to improve the smoother opening of the door, thereby improving the quality and life of the lock, bearings are installed in the existing door lock handle components, but due to some profiles The thickness of the door is relatively thin, and the door leaf is prone to deformation during the installation of the handle, which will cause the door lock to be stuck and the handle cannot be reset normally. Potential safety hazards, such as the installation of emergency access doors

In addition, the existing door handles are widely used to install torsion springs in the handle assembly, and use the effect of the spring torsion to reset the handle. The force and feel are stable during use, and there will be no sagging of the handle during installation. However, due to the shape of the spring and the Influenced by the position, a certain plane space position is required, which is limited in narrow door frame structures such as profile doors, and not only requires a large opening torque, but also causes the handle to fail to reset and sag after long-term use
