Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in detail. Following examples will contribute to this areaTechnical staff further understands the present invention, but does not limit in any form the present invention. It should be pointed out that thisThe those of ordinary skill in field, without departing from the inventive concept of the premise, can also make some distortionAnd improvement. These all belong to protection scope of the present invention.
In the present embodiment, novel adjustable giant-screen provided by the invention lands installing rack and mainly comprises hanger bracketAnd bearing.
Described hanger bracket has two, is contained in respectively top and the middle part of optical axis, with double head belt thread cylinder 12 HesHanger bracket connecting plate 13 is arranged on described bearing. Described hanger bracket is used for installing screen, and adjusting screen angleDegree; Described bearing is used for supporting whole device, and can regulate the height of two screens.
Described hanger bracket comprises angle modulation force rod 1, screen installing plate 2, pull bar 3, contiguous block 4, fan-shaped sawtoothSheet 5, bearing connecting plate 6, clamp 7, stator 8, rigidity studs 9, binding clasp 29, described tuneAngle force rod 1 is inserted in contiguous block 4, and described contiguous block 4 is connected by screw on screen installing plate 2, instituteState pull bar 3 and be connected with angle modulation force rod 1 and rigidity studs 9 by frame for movement, rigidity studs 9Be fixed on stator 8, fan-shaped sawtooth sheet 5 is connected by screw on screen installing plate 2, clamp 7Be connected and fixed by draw-in groove and bearing connecting plate 6, binding clasp 12 is arranged on clamp 7 by screw, fanTooth and binding clasp 29 tooth of being with on shape sawtooth sheet are intermeshing. Pull bar 3, screen installing plate 2, fan-shaped sawtoothSheet 5, bearing connecting plate 6 forms four-bar mechanism, is used for adjusting screen angle; When adjusting, use special hexagonal to pullHand rotating tension bar 3 carrys out adjusting angle.
Described bearing comprises overhead gage 10, upper connecting box 11, double head belt thread cylinder 12, hanger bracket connecting plate13, optical axis 1, optical axis 2 15, leading screw 16, nut 17, axle sleeve 1, lower connecting box 19, lower blockPlate 20, handwheel 21, base 22, chassis pin 23, chassis wheel 24, connecting plate 25, axle sleeve 2 26, axle sleeve3 27, nut 28, vertical position adjustment screw 30, horizontal level adjustment screw 31, described double head belt screw threadCylinder 12 connects hanger bracket connecting plate 13 and upper connecting box 11, and upper connecting box 11 is fixed on optical axis 2 15,Between overhead gage 10 and base 22, be connected with optical axis 1, lower connecting box 19 is by axle sleeve 1 and axle sleeve two26 are enclosed within on optical axis 1 and optical axis 2 15, and are connected on leading screw 16 by nut 17, same, instituteState double head belt thread cylinder 12 and connect hanger bracket connecting plate 13 and lower connecting box 19, connecting plate 25 connects twoOptical axis 2 15, leading screw upper end is connected with overhead gage 10, and lower end is connected with lower baffle plate 20, the centre nut of ining succession17, the nut handwheel 21 of ining succession for bottom, chassis pin 23 and chassis wheel 24 are equipped with in the bottom of base 22, verticallyPosition adjustments screw 30 connects lower connecting box 19 and connecting plate 25, is used for regulating the phase contraposition between sub-screenPut, two horizontal level adjustment screw 31 connect upper and lower connecting box 11,19 and corresponding baffle plate, are used for regulatingThe front and back position of the horizontal direction of upper sub-screen.
Adjustable giant-screen provided by the invention lands the using method of installing rack, it is characterized in that, comprises as followsStep:
Step 1: be connected by screw two screen installing plates 2 and screen
Step 2: if desired regulate screen above, carry out adjusting angle with hexagon wrench special rotating tension bar 3,If the words that screen is below thought adjusting angle are in like manner, be adjusted to behind the position of appointment, rotate binding clasp 29 fasteningStructure.
Step 3: regulate the height of two screens if want, rotation hand wheel 21 gets final product rotational lead screw 16, thereby bandMoving two connecting boxes are up, thereby make to move on two screens.
Step 4: regulate the relative position of two screens if want, by die nut turned position adjustment screw 20Can make the spacing between two screens become large or diminish.
Step 5: if think the position of adjusting screen at horizontal fore-and-aft direction, user can regulate spiral shell by horizontal levelNail 31 is adjusted the horizontal level of upper and lower connecting box, thereby adjusts screen position in the horizontal direction.
In addition, can also increase or reduce according to actual requirement the quantity of screen.
Above specific embodiments of the invention are described. It will be appreciated that, the present invention is not limited toAbove-mentioned specific implementations, those skilled in the art can make within the scope of the claims various distortion or repairChange, this does not affect flesh and blood of the present invention.
