Embodiment
In order that the technical means, the inventive features, the objects and the advantages of the present invention are easy to understand, tie below
Conjunction is specifically illustrating, and the present invention is expanded on further.
Referring to Fig. 1 and Fig. 2, what is provided in figure is that one kind automatically controls lifting screen, including one is used to store screen board 200
Screen outer framework 100, screen board 200, upper slide rail 300, glidepath 400, lifting lever 500,600 and electric pushrod 700.
For the slide arrangement of screen board 200 in screen outer framework 100, the lower edge of screen board 200 is fixedly installed a screen
Wind support bar 210.Upper slide rail 300 is horizontally set on one end of screen supporting bar 210 of screen board 200.Glidepath 400 is horizontal
It is arranged on the bottom of screen outer framework 100 and positioned at the underface of upper slide rail 300.Lifting lever 500,600 is arranged on outside screen
In framework 100, the midpoint of lifting lever 500 is hinged with the midpoint of lifting lever 600 by bearing pin 800, the first end of lifting lever 500
510 by the slide arrangement of top sheave 310 in upper slide rail 300, its second end 520 be hinged on the bottom of screen outer framework 100 and
It is located remotely from the side of glidepath 400, the first end 610 of lifting lever 600 is by the slide arrangement of lower sheave 410 in glidepath
In 400, its second end 620 is hinged on the one end of screen supporting bar 210 away from upper slide rail 300.
Electric pushrod 700 is arranged in screen outer framework 100, and the bottom 710 of electric pushrod 700 passes through a hinged support seat
810 are hinged on screen outer framework 100, and its push rod output end 720 is hinged on lifting lever 600 by a hinged support seat 820
And close to the first end 610 of lifting lever 600.Certainly, the push rod output end 720 of electric pushrod 700 can also be hinged on lifting lever
On 500, second end 520 of its pin joint preferably adjacent to lifting lever 500.
During original state, screen board 200 is located in screen outer framework 100, and electric pushrod 700 is in contraction state.When need
When rising screen, electric pushrod 700 acts and outwards pushes push rod, drives the upper cunning in the first end 510 of lifting lever 500
Lower sheave 410 in the first end 610 of wheel 310 and lifting lever 600 slides to the right respectively along upper slide rail 300 and glidepath 400,
So as to promote screen board 200 to rise, when the protruding ultimate range of the push rod of electric pushrod 700, screen board 200 is raised up to most
High point, as shown in Figure 2.When needing to fall screen, electric pushrod 700 acts and withdraws push rod, drives the of lifting lever 500
Top sheave 310 on one end 510 and the lower sheave 410 in the first end 610 of lifting lever 600 respectively along upper slide rail 300 and under
Slide rail 400 slides to the left, so as to drive screen board 200 to fall, when the push rod of electric pushrod 700 is withdrawn completely, and screen board 200
Minimum point is dropped to, i.e., is incorporated in completely in screen outer framework 100, as shown in Figure 1.
The general principle and principal character and advantages of the present invention of the present invention has been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the simply explanation described in above-described embodiment and specification is originally
