Description
Technical field
Basis is novel discloses the tiltable video presenter of a kind of base.
Background technology
The base of existing exhibition booth generally can not tilt, and is unfavorable for that speaker closely watches by the planographic thing puted on display, when desk is higher, lecturer must stand say or at one end pad add the liner being similar to books etc.
The inclination angle of existing video camera or projector or Height Adjustment are generally come by the adjustment screw arranged on its bottom or the feet that can fold, when adjusting height or inclination angle, entire machine must turn by user, and then parbuckle screw or folding or launch feet in a manual manner.
(application number is Chinese patent " a kind of lathe base adjusting device ": 201310224197.2) disclose a kind of scheme utilizing cam drive conditioning equipment substructure height, as shown in Figure 1, this device comprises lathe support 1, it is column housing 5 above lathe support 1, have cam 3 in column housing 5, cam 3 is connected with column housing 5 by rotating shaft 8.The upper end of cam 3 is fluted, has push rod 6 in groove, and the other end of push rod 6 supports lathe base 4.There is arc-shaped gear the lower end of cam 3, and arc-shaped gear engages with the tooth bar 2 below it, and the other end of tooth bar 2 is positioned at outside column housing 5.The part that tooth bar 2 is positioned at outside column housing 5 has groove, has block 7 in groove.During use, by push-and-pull tooth bar 2, arc-shaped gear and tooth bar 2 is utilized to intermesh, rotate the position height changing cam 3 upper end around its rotating shaft 8 with moving cam 3, and then pass through the lifting of push rod 6 controller bed foundation 4, adopt block 7 to fix when having adjusted, reach the object of freqency fine adjustment machine bed foundation balance.
Summary of the invention
First set screw stroke and scheme that is folding or expansion feet must overturn machine, are inconvenient to use; When lathe arrangement for adjusting height is used for exhibition booth, because the base thickness of exhibition booth is limited, the adjustment space at angle of inclination is little, and adjustable height is also discontinuous.
For solving the problem, basis is novel to be proposed the device of a kind of automation adjustment video presenter angle of inclination or height and applies the video presenter of this adjusting device, is specially:
A kind of video presenter, comprise base, base comprises housing, enclosure interior is formed with accommodation space, it is characterized in that, described base housing (1) is provided with the gradient adjusting device for regulating exhibition booth base gradient, when described gradient adjusting device is run, exhibition booth gradient can recur change in a certain number range.
Further, aforementioned height adjusting device comprises motor, power transmission shaft and at least two cams; Power transmission shaft is fixed on base by bearing block is rotating, and cam is fixedly attached to the two ends of power transmission shaft, and the clutch end of motor is fastened on power transmission shaft.
Further, aforementioned height adjusting device comprises hoisting cross beam, motor and tooth bar; Tooth bar is fixed on the housing of base, and motor is fastened on crossbeam, is connected to gear on the clutch end of motor and tooth bar intermeshes; Hoisting cross beam is provided with feet, base housing offers the perforate of stretching out for described feet or retracting; Base housing is provided with guide pillar in addition, and the corresponding position of hoisting cross beam offers the through hole holding guide pillar.
Further, aforementioned height adjusting device is scissors fork elevating machine, and scissors fork elevating machine comprises power source and scissor structure; Power source is fixed on base housing, and scissor structure movement is connected on base, and when power source starts, scissor structure can rise or decline.
Further, this novel paperweight structure also comprised for fixing paper, this paperweight structure is specially magnetic part and/or elastic clip.This
The novel automation adjustment that can realize angle of inclination, exhibition booth or height by push-botton operation, the large and change of adjusting range continuously.When adopting motor, power transmission shaft and cam scheme, press the button, inclination angle, exhibition booth or highly meeting consecutive variations in a certain scope determined by cam parameter, until highly suitable.When adopting hoisting cross beam, motor and tooth bar, gear structure, motor main story is feet protuberate basic unit housing then, and motor reversal is feet retraction housing then, inclination angle, exhibition booth or highly meeting consecutive variations in a certain scope determined by supporting foot structure.When adopting scissors fork elevating machine scheme, because the horizontal movement being parallel to exhibition booth base can be converted into the vertical motion perpendicular to exhibition booth base by scissor machine, adjustable scope is continuous and excursion is larger.In addition, when adopting this novel angle of paperweight respective outer side edges or arrangement for adjusting height, because the printing class showpiece be seated on exhibition booth or highly can not change and landing occurs because of the angle of inclination of exhibition booth base, result of use is better.
