AI Technical Summary
During the connection process of the multimedia rotating screen, the length of the RF line is not unique, resulting in the excess RF line being dragged on the ground or placed in the air, which will cause wear and damage to the surface of the RF line for a long time, affecting its safety and stability of use.
A multimedia rotary screen radio frequency line is designed, adopting structures such as RF connector, carrier, storage cylinder, limiting clamp and resistance ring block. Through the storage ring groove of the storage cylinder and the limiting function of the resistance ring block, the excess RF wires are stored in the storage cylinder in order to avoid their existence in the external environment.
It effectively avoids the existence of excess RF lines in the external environment, reduces the potential risk of RF lines damage, and improves the safety and stability of RF lines. At the same time, due to the installation of a rotating shaft body, the RF lines can rotate smoothly when the multimedia rotating screen rotates to avoid entanglement.
