Description

LCD monitor holder

technical field

The utility model relates to a liquid crystal display fixing seat.

Background technique

In recent years, liquid crystal displays have gradually replaced traditional fluorescent displays due to their advantages of light weight, thin body, and no radiation. Most of the current liquid crystal displays are composed of a liquid crystal panel and a fixed seat. The fixed seat includes a chassis and a support frame fixed on the chassis. The liquid crystal panel can be directly or indirectly installed on the support frame through the mounting frame. Most of the existing liquid crystal panels cannot adjust the angle left and right. When the user wants to adjust the angle left and right, he must turn the fixing seat completely, which is very laborious to operate.

In addition, existing liquid crystal displays are generally divided into desktop liquid crystal displays and wall-mounted liquid crystal displays. Since the installation positions of the two types of liquid crystal displays are different, the structures of their fixing seats are also different. In order to meet the needs of different customers, some manufacturers Demand often produces two kinds of mounts (table-mounted and wall-mounted) for the same type of display, which requires additional production lines and increases production costs. On the other hand, although customers can choose table-mounted or wall-mounted fixing bases when purchasing, if they want to have both, they often need to spend extra money to purchase, which increases the consumption pressure of customers.
