Description
Technical field
The present invention relates to the technical field of electronic whiteboard, be specifically related to a kind of electronic whiteboard projection location jacking gear.
Background technology
At present, along with the development of multimedia education, various educational patterns are also constantly changing, and electronic whiteboard is widely applied in the daily education life.Electronic whiteboard must carry out adjustment to projector and electronic whiteboard before use, makes the subpoint of projector corresponding with the transmission point signal of electronic whiteboard.Present electronic whiteboard generally all is fixed on wall or the ground through fixed mount in use, and projector then is fixed on the place ahead of electronic whiteboard through other support.But; The upper-lower position that in use usually need regulate electronic whiteboard adapts to the user of different heights; Since moving of electronic whiteboard, and projector can't change the relative position between electronic whiteboard and the projector along with same moved further; So adjustment is again used very inconvenient.
Summary of the invention
Technical matters to be solved by this invention is: provide a kind of when the upper-lower position of mobile electron blank, projector can use the location of electronic whiteboard projection very easily jacking gear along with same moved further.
For addressing the above problem; The technical scheme that the present invention adopts is: electronic whiteboard projection location jacking gear; Comprise fixed mount, described fixed mount is provided with the vertically tressel of activity, is fixed with linear electric motors on the fixed mount; The output shaft of linear electric motors is connected with tressel, and tressel is provided with electronic whiteboard stationary installation and projector stationary installation.
Described electronic whiteboard stationary installation comprises two bottom brackets that are fixed on the tressel lower end and two bracket that are movably arranged on the tressel upper end; Described two bracket fix with the bracket motion bar respectively, and described bracket motion bar penetrates respectively and is arranged in the tressel.
Syndeton between described tressel and the fixed mount is: be fixed with four guide rail sleeves on the fixed mount, be respectively arranged with slide block in the guide rail sleeve, described tressel penetrates and is arranged in the guide rail sleeve.
Can fix with base under the described fixed mount.
Described projector stationary installation comprises the expansion bracket that is movably arranged on the tressel top; Laterally be movably set with expansion link in the expansion bracket; Described expansion bracket is provided with the expansion link fastener; The expansion bracket activity penetrates and is arranged in the expansion bracket cover, and described expansion bracket cover fixes with tressel, and the expansion bracket cover is provided with the expansion bracket fastener.
Described expansion link fastener is the expansion link screw, and described expansion link screw is movably arranged in the expansion bracket through screw thread.
Described expansion bracket fastener is an expansion bracket cover screw, and described expansion bracket cover screw is movably arranged on expansion bracket through screw thread and puts.
The invention has the beneficial effects as follows: above-mentioned electronic whiteboard projection location jacking gear, when the upper-lower position of mobile electron blank, projector can need not adjustment again along with same moved further, thereby can adapt to the user of different heights, and is easy to use.
Description of drawings
Fig. 1 is the perspective view of electronic whiteboard projection of the present invention location jacking gear;
Among the figure: 1, base, 2, fixed mount, 3, guide rail sleeve, 4, tressel, 5, linear electric motors; 6, output shaft, 7, bottom bracket, 8, bracket, 9, the bracket motion bar, 10, expansion bracket; 11, expansion link, 12, the expansion bracket cover, 13, the expansion bracket screw, 14, expansion bracket cover screw.
Embodiment
Through specific embodiment electronic whiteboard projection of the present invention location jacking gear is done further to describe in detail below.
As shown in Figure 1, electronic whiteboard projection location jacking gear comprises base 1; Be fixed with fixed mount 2 on the base 1; Be fixed with four guide rail sleeves 3 on the fixed mount 2, be respectively arranged with the very little slide block of friction factor in the guide rail sleeve 3, tressel 4 penetrates and is arranged in the guide rail sleeve 3; Be fixed with linear electric motors 5 on the fixed mount 2; The output shaft 6 of linear electric motors 5 is connected with tressel 4, thereby tressel 4 can vertically be moved up and down on the edge in guide rail sleeve 3, and tressel 4 is provided with electronic whiteboard stationary installation and projector stationary installation; Described electronic whiteboard stationary installation comprises two bottom brackets 7 that are fixed on tressel 4 lower ends and two bracket 8 that are movably arranged on tressel 4 upper ends; Described two bracket 8 fix with bracket motion bar 9 respectively, and described bracket motion bar 9 penetrates respectively and is arranged in the tressel 4, thereby two bracket 8 can vertically be moved up and down on the edge in tressel 4.Described projector stationary installation comprises the expansion bracket 10 that is movably arranged on tressel 4 tops; Laterally be movably set with expansion link 11 in the expansion bracket 10; Expansion bracket 10 is provided with expansion bracket screw 13, and described expansion bracket screw 13 is movably arranged in the expansion bracket 10 through screw thread, tightens expansion bracket screw 13 expansion link 11 is fixed in the expansion bracket 10; Expansion bracket 10 activities penetrate and are arranged in the expansion bracket cover 12; Expansion bracket cover 12 is provided with expansion bracket cover screw 14, and described expansion bracket cover screw 14 is movably arranged on the expansion bracket cover 12 through screw thread, and described expansion bracket cover 12 fixes with tressel 4; Thereby expansion bracket 10 can be tightened expansion bracket cover screw 14 expansion bracket 10 is fixed in the expansion bracket cover 12 along vertically moving up and down in tressel 4.
Principle of work of the present invention is: during use, above-mentioned base 1 is placed on the ground, also can not used base 1, fixed mount 2 is directly hung on the wall.Electronic whiteboard is fixed on the tressel 4 through bracket 8 and bottom bracket 7, owing to be to flexibly connect between two bracket 8 and the tressel, so upper-lower position that can be through regulating bracket 8 is to adapt to the electronic whiteboards of different sizes; Projector is fixed on the expansion link 11; Because between expansion bracket 10 and the expansion bracket cover 12 is to flexibly connect; So can regulate the upper-lower position of projector through regulating the upper-lower position of expansion bracket 10 in expansion bracket cover 12; Owing to be to flexibly connect between expansion bracket 10 and the expansion link 11, can regulate the front and back position of projector through regulating the front and back position of expansion link 11 in expansion bracket 10.After adjust the above-mentioned electronic whiteboard and the installation site of projector, between projector and electronic whiteboard, carry out adjustment and with the stationkeeping of electronic whiteboard and projector.When the user of differing heights used, stretching out or withdrawing of output shaft 6 that can be through linear electric motors 5 moved up or down tressel 4 in guide rail sleeve 3; Because electronic whiteboard is to be fixed in the tressel 4, thus the upper-lower position adjusting of realization electronic whiteboard, again because projector also is to be fixed in the tressel 4; So tressel 3 is when moving up and down; Relative position between electronic whiteboard and the projector remains unchanged, thus need not adjustment again again, easy to use.
