Description

Cabinet with rotatable and foldable keyboard support

Technical Field

The invention relates to the technical field of cabinets, in particular to a cabinet with a rotatable and foldable keyboard support.

Background

The cabinet is widely applied to the intelligent construction of a community, in the actual use process, network equipment such as a distribution frame and an exchanger generally needs to be assembled in the cabinet, and accessories such as a keyboard and a mouse need to be arranged sometimes so as to facilitate the intelligent control of the cabinet.

For some cabinets with narrow space, the width of the cabinet is narrower than that of the keyboard, and when the keyboard is transversely arranged, the keyboard is easy to interfere with the cabinet and cannot be pulled out of the cabinet for operation; if the keyboard is arranged longitudinally, the longitudinally arranged keyboard is inconvenient for an operator to operate because a person generally stands on the front surface of the cabinet to operate.

On the other hand, because the installation space of the cabinet is limited, when other parts are installed inside the cabinet, installation of other parts is often interfered due to the existence of the keyboard support, and thus installation is inconvenient.

For example, patent "CN 203327414U" discloses a upset key mouse mesa, including key mouse upset mesa and the fixed mesa of fixed mounting on the rack, one side and the fixed mesa upset of key mouse upset mesa are connected, have the keyboard holding tank on the key mouse upset mesa and supply the plane that the mouse used, and the length of key mouse upset mesa is unanimous with the width of rack. In the scheme, a guide rail is not required to be installed, so that the installation and the maintenance are convenient; the length of the key mouse overturning table board is consistent with the width of the cabinet, so that the mouse operating space is large, and the use comfort is greatly improved. However, when the keyboard is provided therein, the operation is inconvenient, and there is still a problem that the table top easily interferes with other mounting parts.

Disclosure of Invention

In view of the above-mentioned shortcomings of the prior art, the technical problem to be solved by the present invention is to provide a cabinet with a rotatable and foldable keyboard support, which has a compact structure and is convenient to operate and install.

The technical scheme adopted by the invention for solving the technical problem is that a cabinet with a rotatable and foldable keyboard support is provided, which comprises:
