[0001] The utility model relates to a turnover mechanism, in particular to a turnover mechanism for a screen cabinet. Background Art

[0002] At present, the turnover of the screen cabinet is manual operation. When the screen cabinet is horizontally turned over, at least 4 people are required to hold the screen cabinet together to lay it down, resulting in difficult turnover. At the same time, too many people are needed to cooperate, wasting human resources. Moreover, during the turnover process, if the cooperating personnel are slightly careless, it is very easy to cause personal injuries and waste time, resulting in low work efficiency.

[0003] In the prior art, the turnover and erection tooling for the screen cabinet disclosed in the patent with the application number CN201621431344.9 still requires two people to cooperate in the operation, and the operation process requires manual coordination; and another patent with the application number CN202021954944.X discloses a horizontal turnover tooling for a cabinet, which requires mechanical cooperation. This tooling not only has a complex structure, but also has a high input cost throughout the process.

[0004] Therefore, in the existing technology, there are still problems such as complex operation process, complex structure, and high input cost. If a turnover mechanism that can be turned over conveniently, has a simple structure, and reduces production costs can be developed, the existing problems can be well solved. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a turnover mechanism that reduces manpower, improves operation efficiency, is safe in operation, and can conveniently lay down and erect the screen cabinet.

[0006] The technical solution adopted by the utility model is as follows: The utility model includes an outer frame and a turnover bracket adapted to the outer frame.
