Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of consoles, and in particular relates to a console and a storage structure in which a cover plate can be embedded in a console table or turned over and hidden under the table. Background Art
[0002] With the application of multifunctional consoles in various industries, the demand for the functions of consoles is increasing; the continuously expanding functional requirements and the various devices have created different console storage box structures. At present, the opening methods of the cover of the console storage box are mainly split type and flip type.
[0003] The traditional split opening method uses a method of separating the cover from the tabletop. The main body and cover of the storage tank are both high-strength cold-pressed steel plates. When the operator needs to use the equipment in the storage tank, the cover is removed and placed aside; after the operation is completed, the cover is placed on the top of the storage tank. This method can ensure that the tabletop is clean and flat when the equipment in the tank is not in use; however, there are the following disadvantages: the operation is complicated, a separate storage position for the cover is required, and the heavy weight of the cover poses a safety hazard.
[0004] The flip-top opening method can solve the problem of cover storage and heavy weight, but its structure is complex and requires a gas spring with high manufacturing and maintenance costs as support. At the same time, it will seriously block the operator's line of sight when opening, which has a great impact on the operation. Therefore, there is still a lot of room for improvement in the above box cover opening methods. Utility Model Content
