NINGBO TUOTUO RIVER DESIGN COMPANY

A top mounting structure for a display device includes: a top mounting bracket and a connecting assembly, where the connecting assembly includes a rotating mechanism and a deployment and retraction mechanism; and the top mounting bracket is used to be fixedly connected with a top ceiling. The rotating mechanism is rotatably connected with the top mounting bracket; and the deployment and retraction mechanism is arranged below the rotating mechanism, and an upper portion of the deployment and retraction mechanism is connected with the rotating mechanism. The deployment and retraction mechanism includes a telescopic part and a movable arm that are connected with each other, where the telescopic part is capable of driving the movable arm to rotate relative to the top mounting bracket, and the movable arm is configured for being directly or indirectly connected with the display device.

The present disclosure provides a height-adjustable mount, comprising a first frame assembly, a second frame assembly, a rotation assembly, and a balance assembly. The first frame assembly includes a first frame and a middle connecting plate coupled to the first frame. The first frame assembly is slidably disposed relative to the second frame assembly. Two rotation assemblies are symmetrically disposed along the first direction, and each rotation assembly includes a first rotating member and a second rotating member. The balance assembly includes two elastic members or assemblies symmetrically disposed along the first direction. Wherein the rotation assemblies enable the first frame to move up and down relative to the second frame and stop at any position under the action of an external force, and the elastic force generated by the elastic member or assembly, the first elastic member and the second elastic member is used to counteract the gravity of the load of the first frame.
