Technical Field
[0001] The utility model relates to the technical field of glass doors, in particular to a smooth rotating shaft structure of a glass movable door. Background Art
[0002] Movable glass doors are divided into sliding glass doors and pivot glass doors. Among them, pivot glass doors are easy to use and are used in many occasions. Most traditional pivot glass doors adopt the method of bottom weighing. A plastic sleeve is set at the bottom of the door frame. After the pivot is inserted into the plastic sleeve, the door and the door frame form a rotating connection. However, when the pivot glass door is in use, the plastic sleeve mainly provides support for the glass door. During use, the end face of the plastic sleeve is easily worn, resulting in the phenomenon of unsmooth closing of the door. Utility Model Content

[0020] The utility model is further described below in conjunction with the accompanying drawings.
[0021] like Figures 1 to 5As shown, a smooth rotating shaft structure of a glass movable door described in the utility model comprises a fixed door 1 and a movable door 2; a guide rail 3 is fixed to the bottom of the fixed door 1; a rotating shaft mechanism is connected between the guide rail 3 and the movable door 2; the rotating shaft mechanism includes a rotating shaft seat 4, a rotating shaft 5 and a supporting member 7; the rotating shaft seat 4 is fixed on the guide rail 3; a positioning sleeve 404 is arranged on the top surface of the rotating shaft seat 4; the supporting member 7 is arranged inside the positioning sleeve 404; the top surface of the supporting member 7 is in an arc shape; the rotating shaft 5 is inserted into the inside of the positioning sleeve 404 and then pressed against the top surface of the supporting member 7; the rotating shaft 5 is rotatably connected to the positioning sleeve 404, and the contact point between the top surface of the supporting member 7 and the rotating shaft 5 is a tangential point contact, so that the rotating shaft 5 can rotate in the positioning sleeve 404 under the stable support of the supporting member 7, combined with the coaxial limiting of the rotating shaft 5 by the positioning sleeve 404. In this structure, the support member 7 with an arc-shaped surface is used to support the rotating shaft 5, which can reduce the resistance of the rotating shaft 5 to rotation on the rotating shaft seat 4 and reduce the wear of the rotating shaft 5 on the positioning sleeve 404, so that the rotation of the movable door 2 is smoother.
[0022] As a preferred embodiment of the utility model, the support member 7 is a ball; the diameter of the ball is less than or equal to the diameter of the positioning sleeve 404; the ball can rotate freely in the positioning sleeve 404, which can further reduce the resistance of the rotating shaft 5 to rotation on the support member 7; and the ball is a standard part, reducing the total cost of the entire rotating shaft structure.
