Description

Technical Field

[0001] The utility model relates to the technical field of the middle support structure of an electric screen, in particular to an extra-long electric screen with a shell-separated middle support structure. Background Technique

[0002] The middle support of an electric screen refers to a device that supports the electric screen and is responsible for transmitting the power from the motor to the screen. Generally, there are two middle supports, which are respectively distributed on the left and right sides of the screen. They are connected to the motor through their own flywheels and drive the screen to rotate to realize the retraction and extension of the screen. The middle support structure of the electric screen is usually fixed on the wall with bolts, which is convenient for the installation and use of the electric screen.

[0003] For example, an extra-long upper-rolling electric screen middle support structure with the publication number of CN216145074U mainly realizes the function of preventing gear wear by setting a support plate, a moving hole, a bearing mechanism, a connecting column, a rotating column, a passive gear, etc. The motor drives the flywheel to rotate, so that the internal rack on the left side of the flywheel can mesh with the passive gear and drive the passive gear to rotate, so as to improve the torque of the passive gear and avoid the wear of the passive gear. At the same time, by setting a support bearing to fixedly connect the connecting column and support its downward movement, and by setting a support column to move downward and compress the support spring, the connecting column moves downward when encountering a heavy electric screen and passes through the moving hole, and then drives the passive gear to move downward, and finally meshes with the spare gear, so that the flywheel drives the spare gear to rotate while driving the passive gear to rotate to realize the seamless transmission of the passive gear.
