The electric pull-wire screen features pull wires on both sides of the screen, which are connected to pulling mechanisms on both sides of the lower end of the screen. The lower end of the screen is equipped with a pull-down box, and two pulling mechanisms are located inside the pull-down box, positioned at both ends of its length. Each pulling mechanism includes a guide moving column and an eccentric wheel.
The electric pull-wire screen features pull wires on both sides of the screen, which are connected to pulling mechanisms on both sides of the lower end of the screen. The lower end of the screen is equipped with a pull-down box, and two pulling mechanisms are located inside the pull-down box, positioned at both ends of its length. Each pulling mechanism includes a guide moving column and an eccentric wheel. One end of the guide moving column is equipped with a spring, while the other end is equipped with an eccentric wheel. The guide moving column is fitted with a fixed ring, and the pull wire is connected to the fixed ring. When water ripples or V-shaped patterns appear on the screen, this electric pull-wire screen can adjust the lateral tension of the screen by adjusting the eccentric wheel. Under the synergistic action of the eccentric wheel and spring, the guide moving column can drag the pull wire to drive the screen side to produce a certain amount of displacement. The pulling mechanisms on both ends of the pull-down box work together to adjust the lateral tension of the screen, thus quickly and easily eliminating water ripples or V-shaped patterns, achieving the purpose of adjusting the flatness of the screen, improving the viewing experience, and extending the service life of the screen.
