Problems solved by technology

Since the thickness of the lower shaft assembly is generally more than 30 mm, and the thickness of the floor and floor tiles is generally not more than 16 mm, the lower shaft assembly needs to be pre-embedded in the concrete floor before the installation of the floor spring, or the cement floor should be cut on site. It is very inconvenient to install

Abstract

The invention discloses a bidirectional automatic door closing device realizing fast mounting. Functions of an upper shaft component and a lower shaft component are reassigned, wherein the upper shaft component comprises an upper shell, an upper shaft, a jack screw, a spring and a steel ball; the lower shaft component comprises a lower shell and a lower shaft; the lower shaft comprises a lower shaft rod and a lower bearing; and the lower bearing is a rolling bearing. By assigning a power transmission device comprising the jack screw, the spring and the steel ball of the automatic door closing device onto the upper shaft component, the lower shaft component only has the functions of bearing a door weight and rotation, therefore, the thickness of the lower shaft component is reduced; and the thickness of the lower shaft component can be further reduced by adopting the rolling bearing, such that the thickness of the lower shaft component is lower than the that of a floor and a tile, the lower shaft component is not needed to be pre-buried in a mounting process or a cement ground is not needed to be cut, the mounting process of the bidirectional automatic door closing device is simplified, and an installation rate is accelerated.

Description

technical field [0001] The invention relates to the technical field of automatic door-closing equipment, and more particularly, to a two-way automatic door-closing device that realizes quick installation. Background technique [0002] In modern interior decoration, the doors used mainly include swing doors, sliding doors, folding doors, revolving doors, two-way swing doors, etc. Among them, the two-way swing doors can be opened and closed in both directions, and have the advantages of flexible and labor-saving opening and closing. Space-saving and high security advantages. [0003] In order to further facilitate the use, the two-way swing doors, especially the two-way swing doors in the office space, are equipped with automatic door closing equipment to achieve the purpose of automatic door closing and damping buffer. [0004] In the existing two-way automatic door closing equipment, floor springs are most commonly used, and the floor springs realize the automatic closing f...
