This utility model discloses a more stable floor tile screen structure, belonging to the technical field of floor tile screens. The floor tile screen includes a frame, a first support frame, and a second support frame. The first support frame is located on the left and right sides inside the frame, and the second support frame is located in the center. The first support frame consists of a first horizontal rib, a first vertical rib, and a support rod. The first horizontal rib is installed at the head and tail of the first vertical rib and is connected to the frame through the support rod. The first vertical rib has reinforcing ribs and interlocking structures. The second support frame includes a second horizontal rib and a second vertical rib, on which a power box with a power supply cover is installed. The top of the frame has a light hole, and the sides have mounting holes. This utility model improves the stability of the floor tile screen through the synergistic effect of multiple support structures, while integrating power supply and installation interfaces. It features diverse functions, convenient installation and maintenance, and is suitable for various architectural scenarios.

This invention discloses a transmission gear shaft for a planting tray conveying system, belonging to the technical field of transportation equipment. It aims to solve the problems of noise generated by gear disk displacement under force and gear disk corrosion caused by condensation. The transmission gear shaft includes a central shaft, a first spacer, a second spacer, a gear disk, and a hollow shaft. The first and second spacers are fixed to the central shaft, which can limit the displacement of the gear disk under force and reduce noise. The first spacer, the second spacer, and the through holes on the gear disk are coaxial. The clearance fit between the hollow shaft and the central shaft forms an air duct. After the air duct is connected to a fan, it can accelerate the evaporation of condensation on the surface of the central shaft, prevent corrosion at the connection between the gear disk and the central shaft, extend the service life of components, and ensure the stable operation of the planting tray conveying system.
