Screen bracket device

The present invention provides a screen bracket device, in particular, the upright rod of the base is a first pivoting portion that is sleeved with a first supporting arm, and the second pivoting arm of the second supporting arm is coaxially mounted on the first pivoting portion. The connecting portion enables the limiting groove of the second pivoting portion to cooperate with the stopping body of the first pivoting portion to limit the angle of rotation thereof, thereby achieving the advantages of simple structure and convenient operation.

According to the screens and TVs used in home life, offices, schools or various workstations, it is very common, and the screens from the early image tube type have been large due to their large size, poor quality, and only analog signals. The place is eliminated, replaced by a light, thin, clear picture and a liquid crystal or plasma type screen that can receive analog or digital signals at the same time, but the thin and light screen can only be rotated or adjusted on the provided base. For a small range of angle adjustments, and must pay attention to the position of the center of gravity of the screen to avoid dumping, or install the screen on the wall through the rack, which ensures the stable positioning of the screen, but it is not convenient to adjust the screen. The position and angle of the installation will cause the screen to be subject to many restrictions when applied.

In order to satisfy the user's need to freely adjust the viewing angle of the screen and reduce the space and position of the screen occupying the desktop or the workstation, the screen is generally mounted on a support frame that can be steered and supported to be positioned, and the clip is fixed by the support frame. The seat or wall seat can be installed on the table top, the pylon or the wall surface, so that the user can freely adjust the screen by using the plurality of arms of the support frame. The angle of view and location, but the user's actual application will have the dual screen synchronization display screen requirements, can be divided into execution, multiplex monitoring, so that homework and work are convenient and efficient, but every screen in the home or office The application of a base not only occupies a large space on the desktop, but also limits the adjustable viewing angle of the two screens to the limited space of the desktop, which is not easy to operate, and also affects the efficiency of the user's work and work. There are still many The lack of inconvenience is the key to the research and improvement of those who work in this industry.

Therefore, in view of the above-mentioned problems and shortcomings, the new creators have collected and researched relevant materials through various evaluations and considerations, and have been using the trial and modification of many years of R&D experience in this industry. .

The main purpose of the present invention is that the upright rod at the top of the base is provided with a protruding portion, and the first pivoting portion of the first supporting arm has a sleeve that is sleeved on the upright rod so as to be stopped on the protruding portion. a first shaft hole, and a stopper body is disposed at a periphery of the first pivoting portion, and the second pivoting portion of the second supporting arm has a second shaft hole coaxially mounted on the first pivoting portion inside the peripheral wall, and a limiting slot spanning to a periphery of the stopping body is formed at a bottom of the peripheral wall, and the first extending portion of the first supporting arm and the second extending portion of the second supporting arm are respectively connected by the first pivoting portion and the first pivoting portion The periphery of the second pivoting portion extends horizontally outward for supporting the screen. When the second pivoting portion of the second supporting arm rotates coaxially with respect to the first pivoting portion of the first supporting arm, the two side walls of the limiting slot can be Any resisting surface is rotated against the stop body to limit the angle of rotation, so that the user can easily adjust the orientation of the screen rotation, thereby achieving a simple structure and convenient operation.

The second purpose of the present invention is that the first supporting arm and the second supporting arm further comprise a pair of connecting seats, and respectively have a frame on the first extending portion and the second extending portion, and each outer frame Each of the interiors is formed with a sliding space laterally, and the connecting seat comprises a body, and a connecting portion for sliding displacement in the sliding space is arranged at the rear of the body, and a fixing plate mounted on the back of the screen is respectively arranged at the front of each body, so that The screen can be adjusted by lateral sliding displacement along the first extending portion and the second extending portion by the connecting seat.
