Bearing lock

Abstract

The invention discloses a bearing lock and relates to the field of locks. The bearing lock is technically characterized in that the bearing lock comprises a door lock panel, a bearing installed on the door lock panel, and a lever handle rotating shaft inserted in a bearing inner hole, and the bearing is connected with the door lock panel through a connecting structure arranged on the bearing; the outer edge, away from the door lock panel, of the bearing inner hole extends along the inner circle of the bearing to form a concave edge, and the concave edge is abutted against the outer ring of the bearing. Due to the arrangement of the connecting structure and the concave edge, the bearing clamped to the bearing inner hole is always located in the bearing inner hole, and the bearing is prevented from sliding out of the bearing inner hole in the use process. Compared with the Chinese utility model file which is mentioned in the background technology and has the application number of 2008201752246, the bearing lock is advantageous in that the service life of the bearing or the service life of the bearing lock is remarkably prolonged in the use process due to the fact that screw holes and set screws are omitted.

Description

technical field [0001] The invention relates to the field of locks, and more specifically relates to a bearing lock. Background technique [0002] Door locks are the most common daily necessities and are divided into many categories. At present, the most widely used is the handle door lock. [0003] For example, the Chinese utility model document whose application number is 2008201752246 discloses a bearing lock. The structure of the patented product is simple, and the handle is easy to install. The characteristics of the connection structure between the lock panels are very popular with the applicant, but the applicant finds that the patented product still has the following problems: referring to the specific implementation method of the above patent specification, it can be seen that on the door lock panel (2) close to the bearing The outer edge of (3) is provided with a screw hole, and the fixing screw (7) for fixing the bearing is installed in the screw hole.

[0003] For example, the Chinese utility model document whose application number is 2008201752246 discloses a bearing lock. The structure of the patented product is simple, and the handle is easy to install. The characteristics of the connection structure between the lock panels are very popular with the applicant, but the applicant finds that the patented product still has the following problems: referring to the specific implementation method of the above patent specification, it can be seen that on the door lock panel (2) close to the bearing The outer edge of (3) is provided with a screw hole, and the fixing screw (7) for fixing the bearing is installed in the screw hole. The opening of the screw hole destroys the overall structure of the door lock panel (2) and reduces the service life
