Abstract

The invention discloses a rotatable mechanism of a box body cover plate. The rotatable mechanism of the box body cover plate comprises a box body and a box cover. The box body and the box cover are arranged on a multi-media platform, wherein two sides of an edge of the box cover are hinged on a hinged shaft of the box body through connecting components, one of the connecting components is a toothed plate and matched with a gear arranged on the box body, and the other connecting component is provided with a lock catch and matched with a limiting device which is arranged on the multi-media platform or on the box body. A torsional spring is arranged on the section, between the box body and the box cover, of the hinged shaft. By the adoption of the rotatable mechanism, the opening and closing of the box cover can be controlled by the limiting device, the box cover can achieve the automatic opening through the toothed plate being matched with the gear which is arrange on the box body under the action of the torsional spring, and the arrangement of a damping gear enables the box cover to keep a slow speed and noiseless when the box cover opens.

Description

technical field [0001] The invention belongs to a rotating mechanism, in particular to a rotating mechanism for a box body cover. Background technique [0002] The existing multimedia podium panels are all equipped with interface box devices, and the cover plates generally adopt hinges to turn outwards, or adopt internal pulley sliding and other opening and closing methods. The hinge is turned outward, the hinge is welded to the box body and the cover, the hinge shaft is outside the cover, and the hinge leaks outside after the cover is turned up, which is poor in aesthetics. Using the pulley sliding method, a small pulley needs to be added under the cover plate, which increases the cost and makes the noise larger when the cover plate slides. Contents of the invention [0003] The purpose of the present invention is to provide a rotating mechanism that can automatically open the noiseless box body cover. [0004] The technical scheme that realizes the object of the presen...
