When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0028] In view of this, the main purpose of the utility model is to propose a magnetic structure and a display screen, aiming to solve the technical problem in the background technology that a display screen without a bottom shell is easily dropped when only fixed by magnetic attraction, thereby improving the safety of the display screen.

[0030] It should be noted that the clamping portion 111a in this embodiment includes a variety of implementation methods to adapt to different assembly requirements and application scenarios. The clamping portion 111a can be expressed as a number of grooves arranged along the periphery of the magnetic iron sheet 110, which are used to set the connecting parts of the connecting box 300, such as buckles or other mechanical fasteners, so as to provide additional support force to prevent the display module 200 from falling off directly due to magnetic failure or external vibration. In addition to the grooves, the clamping portion 111a can also adopt other forms of clamping structures, such as convex strips, hooks, annular buckles, spring buckles, etc., as long as a stable mechanical connection can be established between the magnetic iron sheet 110 and the box 300, they all belong to the scope of protection of the utility model. The design of these clamping structures takes into account different connection requirements and environmental factors. For example, the convex strips can form a close fit with the corresponding notches on the box 300 to provide radial support; the hooks and annular buckles are suitable for occasions where frequent disassembly and assembly are required, and the operation is simple and the connection is stable; the spring buckle uses elastic force to maintain the connection state, which is suitable for environments with large vibrations.
