Novel convenient transportation LED backlight module
ActiveCN224287305UComprehensive restrictions up and downComprehensive restriction of horizontal displacementOptical light guidesNon-linear opticsStructural engineeringMechanical engineering
This utility model discloses a novel LED backlight module that is convenient for transportation, relating to the technical field of backlight module technology. The utility model includes an outer frame, with a baffle connected to the upper part of the inner side of the outer frame. Buckles are connected to both sides of the baffle, and a cushioning pad is connected to the bottom of the baffle. Through the baffle and buckles, this utility model effectively shields the light-shielding film and the bent flexible flat cable, preventing direct contact and friction with other modules during transportation. Simultaneously, the buckles securely fasten the baffle to the top of the outer frame, and the abutment between the baffle and the inner wall of the outer frame around its perimeter comprehensively restricts the vertical and horizontal displacement of the baffle, ensuring the stability of the protective structure and reducing the risk of damage to the light-shielding film and flexible flat cable. This facilitates the protection of the light-shielding film and flexible flat cable during transportation.

Sunlight greenhouse sunshade net winding device
The application belongs to the technical field of auxiliary device of greenhouse, and discloses a sunshade net winding device for sunlight greenhouse, which comprises a winding assembly and a guide assembly. The winding assembly comprises a driving part, an auxiliary rod and a sunshade cloth. The driving part is arranged at one end of the auxiliary rod and is used for driving the auxiliary rod to rotate. One end of the sunshade cloth is fixed to the top of the back wall of the greenhouse, and the other end is fixed and wound on the auxiliary rod. The guide assembly comprises an auxiliary plate and a friction part. The auxiliary plate is arranged at the bottom of the driving part, and the friction part is arranged on the auxiliary plate and is used for determining the moving direction of the driving part and limiting the horizontal displacement of the driving part. By arranging the friction part, the friction part moves on the cotton cloth. When the auxiliary rod deviates to one side, the side wall of the friction part is rubbed and clamped in the wrinkle of the cotton cloth after being pulled, so as to limit the horizontal displacement of the motor and the auxiliary rod. At the same time, the friction part can move along the arc surface of the gable, so as to play a good guiding role.
