translation, I 1-11 of driven pulley drives two-way worm screw 1-10 rotation, two-way worm screw 1- 10 be the worm screw of bidirectional helical, and partial threads of the two-way worm screw 1-10 in the two sides worm bracket 1-7 are contrary;Shield frame using rotation When 2, the screens such as LED screen can be installed in display/panel bracket 2-1, the rotation screen frame 2 of two sides passes through upper shaft 2-2 and lower rotary shaft 2-3 is rotated between cross tube 1-2 and the two sides of sheer pole 1-3, the two sides with two-way worm screw 1-10 respectively I 2-6 of worm gear of two sides Engaged transmission, when two-way worm screw 1-10 rotation, due to contrary, the worm gear of two sides of the screw thread of the two sides two-way worm screw 1-10 The rotation of I 2-6 also can be contrary, and I 2-6 of worm gear of two sides drives the worm gear shaft 2-5 of two sides to rotate respectively, the worm gear shaft of two sides 2-5 drives II 2-7 of driving pulley of two sides to rotate respectively, and II 2-7 of driving pulley of two sides passes through V belt translation respectively and drives two sides Driven pulley 2-4 rotation, the driven pulley 2-4 of two sides pass through respectively two sides upper shaft 2-2 drive two sides display screen branch Frame 2-1 rotation, because two-way worm screw 1-10 rotation will drive I 2-6 opposite direction of the worm gear rotation of two sides, when I 1-8 of motor revolves When turning to drive two-way worm screw 1-10 rotation, synchronous rotary that the display/panel bracket 2-1 of two sides can be relatively reversed;Make I 1-8 of motor just To when rotation, edge card of the display/panel bracket 2-1 meeting relative rotation of two sides on the inside of the display/panel bracket 2-1 of two sides is in On hinged arm 1-1, the outer surface of two display/panel bracket 2-1 can make the screen on two display/panel bracket 2-1 in same plane at this time Curtain is spliced into a monolith large screen;Rotate backward I 1-8 of motor, until the edge difference on the inside of the display/panel bracket 2-1 of two sides When being stuck on the lever 1-4 of two sides, two display/panel bracket 2-1 are mutually opposite facing and parallel, at this time two display/panel bracket 2-1 courts To two sides of the invention, content can be shown to two sides simultaneously;Due to the self-locking property of Worm Wheel System, in two display screen branch Frame 2-1 can stop I 1-8 of motor during rotation in stroke at any time according to demand, make two display/panel bracket 2-1 towards institute The direction needed;Two display/panel bracket 2-1 can be used for the place that market etc. needs promotional content, and the present invention is placed on two-way people The center of stream can allow the stream of people of two sides that can watch the content played in screen, when user explains content When etc. large screen is needed, two display/panel bracket 2-1 can be spliced into one piece of large screen, convenient for explanation and large screen is convenient for Spectators watch the content in screen;When using attachment base 3, II 3-6 of motor is controlled by conducting wire and power supply, and II 3-6 of motor drives Disk 3-7 rotation, disk 3-7 drive eccentric shaft 3-8 to move in a circle around the center of circle of disk 3-7, and eccentric shaft 3-8 drives connecting rod 3-5 movement, connecting rod 3-5 drive support arm 3-4 movement, and support arm 3-4 drive support shaft 3-3 does the swing of certain angle, with this Make support shaft 3-3 that maincenter frame 1 and rotation screen frame 2 be driven to rotate;When rotation screen frame 2 shows content, exhibition can be increased by swinging The angle shown makes pedestrian be easier to notice the content that rotation screen frame 2 is shown, and when pedestrian is mobile, the swing of rotation screen frame 2 It can make the angle of screen that pedestrian be followed to move a certain distance, allow pedestrian that the content in rotation screen frame 2 is more easily observed;It is using When going up and down storehouse 4, upper turntable 3-9 can hingedly make lower turntable 4-4 that can relatively rotate with upper turntable 3-9 with lower turntable 4-4's, install When bolt 4-6, first bolt 4-6 is inserted into the hole of the vertical pole on the outside of bolt frame 4-5, is then mounted in compressed spring 4-7 On bolt 4-6, then gasket 4-8 is threadedly attached on bolt 4-6, finally bolt 4-6 is inserted on the inside of bolt frame 4-5 In the hole of vertical pole;When the angle of rotation screen frame 2 of the invention is not easy to viewer's viewing, bolt 4-6 is pulled out, is made The inner end of bolt 4-6 skids off jack 3-10, after the relative angle to proper angle for adjusting lower turntable 4-4 and upper turntable 3-9, decontrols Bolt 4-6 makes the inner end of bolt 4-6 be inserted into the jack 3-10 of corresponding position, with this by the phase of lower turntable 4-4 and upper turntable 3-9 Angle is fixed;When needing to adjust height to the desired height of rotation screen frame 2, III 4-10 of driving motor rotation makes lifting tooth 4-15 rotation is taken turns, lifter plate 4-3 can be driven in outer warehouse 4- by the engaged transmission with rack gear 4-9 when lifting gear 4-15 rotates It is slided up and down in 1, four guide rod 4-17 can limit lifter plate 4-3, deflect lifter plate 4-3 will not, four guiding The top of bar 4-17 is equipped with the disk that an outer diameter is greater than four guide rod 4-17 bodies of rod, and can block lifter plate 4-3 makes to go up and down Plate 4-3 is without departing from outer warehouse 4-1, due to the latching characteristics of worm and gear, when III 4-10 of motor does not rotate, lifter plate 4-3 It will go up and down and be maintained at height when III 4-10 of motor stops, when not needing using the present invention, by two display/panel brackets 2-1 rotates on the lever 1-4 for being stuck in two sides to the edge on the inside of the display/panel bracket 2-1 of two sides, at this time two display screens The distance of bracket 2-1 expansion is most short, then lifter plate 4-3 drops to lowermost end, keeps maincenter frame 1, rotation screen frame 2 and attachment base 3 equal Drop in outer warehouse 4-1, the protection to maincenter frame 1, rotation screen frame 2 and attachment base 3 can be realized with this;After the completion of contraction, The form of outer warehouse 4-1 cube is more convenient for movement and transport of the invention, and the present invention is made to can be used for more scenes.
Certainly, above description is not limitation to invention, and the present invention is also not limited to the example above, the art it is general The variations, modifications, additions or substitutions that logical technical staff is made within the essential scope of the present invention also belong to protection of the invention Range.
