A rotating support seat for door leaf

Abstract

The invention relates to the technical field of door shaft supporting, in particular to a rotary supporting seat for a door leaf. The supporting seat comprises a corner wrapping member, the horizontalbottom face of the corner wrapping member is fixedly provided with a cushion block, the lower surface of the cushion block is fixedly provided with an upper spherical ball hood, the cushion block isfixedly provided with a hood housing, the lower end port of the hood housing is integrally and fixedly provided with an inner extending ring plate extending in the radial direction, the center of theinner extending ring plate is rotatably connected with a load bearing assembly, the load bearing assembly comprises a rotary disc, both upper and lower end faces of the rotary disc are fixedly provided with an upper load bearing ball head and a lower load bearing ball head, the upper load bearing ball head is in cooperative contact with the inner surface of the ball hood, and the rotary disc is rotated around a fixed shaft in the hood housing and located above the inner extending ring plate. The rotary supporting seat for the door leaf has the advantages that the distribution uniformity of loads is improved to prevent wearing aggravation caused by excessive deflection, impurities are prevented from entering the part between moving members to cause wearing damage, the rotation flexibility of the door leaf is improved, and the service life of a whole supporting structure is prolonged.

Description

technical field [0001] The invention relates to the technical field of door shaft support, in particular to a rotating support seat for a door leaf. Background technique [0002] The door leaf is a commonly used and important part in the building. In some places with larger specifications or more high-grade places, the door leaf used is relatively heavy and wide. The supporting part at the rotating shaft of the door leaf is particularly important. The weight and rotation torque are also relatively large. The existing support components often use spherical seat structures, which are relatively easy to damage, and the structure is open, so it is easy for sundries to enter the rotation gap, resulting in increased wear, reduced service life and door leaves. The smoothness of opening and closing, in view of this, we propose a rotating support seat for the door leaf. Contents of the invention [0003] The object of the present invention is to provide a rotating support seat for...
