Description

Technical Field

[0001] This utility model relates to the field of monitor stand technology, specifically to a TV stand that can be freely raised, lowered, and rotated. Background Technology

[0002] A TV stand is a functional accessory used to support and secure a television set, providing a stable support surface and ensuring the TV remains balanced on flat surfaces such as desktops and floors, preventing it from tipping over. Choosing the right TV stand can effectively optimize the user experience of televisions and other displays, especially in scenarios involving long hours of office work or collaborative work with multiple people, where its ergonomic design can significantly reduce health risks and improve work efficiency.

[0003] Current mainstream TV stands offer limited functionality, generally providing only basic support and failing to meet users' personalized needs for height adjustment and rotation. Traditional designs mostly support fixed height or manual adjustment via mechanical knobs, and screen rotation cannot be synchronized during lifting. Their hovering function often relies on complex hydraulic or pneumatic structures, resulting in high costs and maintenance difficulties. Furthermore, existing stands with rotation functions typically employ a separate lifting and rotation mechanism, requiring the installation of an independent lifting component. This not only creates structural redundancy and space consumption but also increases the complexity of user operation, making it difficult to adapt to the flexible interactive usage scenarios of modern smart devices.

[0004] Therefore, there is an urgent need to design a TV stand that integrates lifting and rotating functions, is easy to operate, and has a reliable structure, allowing for free lifting and rotating. Utility Model Content

[0005] The purpose of this invention is to address the problems of existing TV stands being functionally limited, generally only providing fixed support and failing to meet users' needs for TV height adjustment and angle rotation, as well as their redundant structure and cumbersome operation. This invention designs a freely height-adjustable and rotatable TV stand, allowing free rotation at any position during the height adjustment stroke, thus combining rotation and height adjustment functions. The technical solution adopted is as follows:

[0006] A freely height-adjustable and rotatable TV stand includes a base and a column. The column is fixed above the base, and a lifting mechanism assembly and a rotating mechanism assembly are installed inside the column. The lifting mechanism assembly includes a constant force spring, a slide rail assembly, a lifting slider, a lifting iron piece, and a column iron piece. The constant force spring is located on the top of the column iron piece. The slide rail assembly, lifting slider, and lifting iron piece are located inside the column iron piece. The lifting slider is located on the slide rail assembly, and both sides of the slide rail assembly are fixedly connected to the column iron piece. A bearing assembly is installed on the lifting iron piece of the lifting mechanism assembly. The rotating mechanism assembly includes a rotating die-cast part, a rotating fixed iron piece, a rotating friction plate, and a rotating fixed friction plate stacked together in sequence. An adjusting screw passes through the rotating die-cast part and is threadedly connected to the rotating fixed iron piece, the rotating friction plate, and the rotating fixed friction plate. The fixing is adjusted by adjusting the tightening force of the adjusting screw.

[0007] Preferably, the slide assembly includes a left slide and a right slide, which are inserted into the positioning holes of the column iron piece and symmetrically fixed on both sides of the column iron piece.

[0008] Preferably, the bearing assembly includes a bearing and a bearing pin, wherein the bearing is fixed to both sides of the lifting iron component by the bearing pin.

[0009] Preferably, the display is fixedly mounted on the rotary die-cast part via a connecting plate.

[0010] Compared with the closest existing technology, the technical solution provided by this utility model has the following beneficial effects:

[0011] This utility model integrates a lifting and rotating mechanism into a single design, requiring no additional components, resulting in a compact and space-saving structure. The television can be freely raised and lowered via the lifting mechanism, and can be suspended at any position. The rotational force of the rotating mechanism can be adjusted by tightening the screws. The slide rail assembly adopts a symmetrical double-slide rail design, enhancing lifting stability. The bearing assembly reduces mechanical wear and extends service life. This utility model features a purely mechanical structure, requiring no electricity. Users can easily adjust the rotation and height by gently pushing the monitor bezel, resulting in low maintenance costs. Attached Figure Description
