Description

Driving structure of electric partition screen

Technical Field

The utility model relates to an electronic screen technical field specifically is a drive structure of electronic wall screen.

Background

At present, domestic movable sound-insulation partition screens all adopt the following structures: the aluminum alloy slide rail is arranged on a ceiling through a steel structure and a screw rod, a plurality of N hanging wheels are arranged in the slide rail, and the hanging wheels can slide in the slide rail. The hanging wheels are respectively connected with the panels of the individual screens, and the screens are internally provided with telescopic mechanisms; when a large space needs to be divided into small spaces, the screen panels are pushed to slide to the positions of the partitions one by one manually along the trend of the sliding rails, and the male and female aluminum materials on the side surfaces of the screen panels are spliced. In the splicing operation, after the screen panels are spliced one by one, the top support and the bottom support of each screen are extended out by a manual stirring telescopic mechanism to be propped to the upper sliding rail and the ground, and finally, a sound insulation partition wall is formed; when a large space is needed, the reverse operation is also manually adopted to fold the screen together, a special storage room can be also arranged, and the screen panel is stored in the storage room, so that the appearance is not influenced. In the above operation, the movement of the screen panel, the butt joint of the screen male master batch and the expansion of the top and bottom supports in the screen are all operated manually, and the defects are as follows:

(1) time and labor are wasted, and the working efficiency is greatly reduced;

(2) the splicing position of the screen panels is flexible, so that gaps among the screen panels are large and small, and the sound insulation and the overall attractiveness are affected;

(3) the manual splicing force is different in size, and the service life of the screen can be influenced by repeated large-force collision.

In order to solve the above problems, the patent numbers are successfully applied: although the patent ZL 201320515575.4 patent of a full-automatic intelligent movable sound insulation partition screen solves the problems, the patent still has a defect that the screen body cannot rotate due to the fact that the gear and the bearing pulley screw are not coaxial and are fixedly installed in the screen, and therefore the screen cannot be well applied to partial setting scenes. Referring to fig. 1 to 3, in a first scenario, when the screen is cut off, the screen is in a state of being parallel to the sliding rail up and down, and when the screen is stored, the screen is required to be rotated by 90 degrees and then stacked to the side surface to be parallel to the wall surface, at this time, because a fixed distance of 35mm exists between the gear and the pulley suspender in the original patent and the gear and the pulley suspender are fixed in the screen body, when the screen is rotated, the gear is disengaged and the pulley suspender is collided with the edge-closing aluminum, so that the screen body cannot rotate; referring to fig. 3 to 6, in a second scenario, the slide rail is provided with an arc-shaped turning position, and the slide rail can be stacked on the side surface to be parallel to the wall surface after being rotated by 90 degrees during storage, and at this time, the screen cannot be rotated, so that the patent cannot be applied in this scenario.

In order to solve the above problems, the present invention provides a novel driving structure of an electric partition screen, which has the advantages of simple structure, low cost, convenient maintenance and application to various scenes.
