Be mainly to offsetting mechanism and realize vertically moving for activity plate face 8, thus by pulley 21 abutted with transverse moving mechanism be connected,
Resistance each other can be reduced, facilitates vertical misalignment mechanism to be vertically moved in lateral shift mechanism.
Straight line between air line distance between the pulley 21 of 4 direction of straight guide two and two arcs skew guide rail 5 end away from
From equal.
The transverse moving mechanism includes the transverse moving mechanism frame 11 being movably arranged in vertical misalignment mechanism rack 9,
The top of transverse moving mechanism frame 11 and it is respectively provided on two sides with the chute being engaged with the bearing 22 in vertical misalignment mechanism rack 9
13, in the universal wheel 12 and directive wheel 14 that are respectively arranged at two ends with the mating connection of upper saddle 2 of transverse moving mechanism frame 11.Laterally
Travel mechanism is connected with vertical misalignment mechanism using clamp mode, makes its assembling very convenient, and due to vertical misalignment mechanism
It is pressed on transverse moving mechanism by bearing 22, mounting stability is good.
The middle part of the universal wheel 12 is provided with groove, is provided with along the direction of straight guide 4 in the outer upper surface of upper saddle 2 and matched somebody with somebody with groove
The raised gib block 15 for setting is closed, is provided with along the direction of straight guide 4 in the inner side of upper saddle 2 and is coordinated that installs to lead with directive wheel 14
To wheel draw-in groove 16.It is more stable that gib block 15 and directive wheel draw-in groove 16 run lateral shift mechanism.
The guiding mechanism includes the guide rail identical guide rail being located on the structure of the bottom of lower slider 3 and upper saddle 2, glides
The guide rail of seat 3 is relative with the guide rail position of upper saddle 2 and be symmetrical arranged, and is provided with lower slider 3 and is slidably mounted on two respectively and leads
Slider roller 20 in rail, two slider rollers 20 are oppositely arranged with two vertical misalignment mechanism positions respectively.Guiding mechanism is mainly right
Guide effect is played in the motion of activity plate face 8, and is equipped with the vertical misalignment mechanism of setting on upper saddle.
The guiding mechanism includes the guide rail identical guide rail being located on the structure of the bottom of lower slider 3 and upper saddle 2, glides
The guide rail of seat 3 is relative with the guide rail position of upper saddle 2 and is symmetrical arranged, and one is movably equipped with respectively on the guide rail of two lower sliders 3
The vertical misalignment mechanism that position is oppositely arranged with vertical misalignment mechanism on upper saddle 2, the vertical misalignment on two lower sliders 2 is inter-agency
Every arrangement, lower supporting plate 7 is installed in two vertical misalignment mechanisms lower section, and activity sets a horizontal stroke respectively in offsetting mechanism longitudinally in each
To travel mechanism, transverse moving mechanism is movably connected with lower slider 3.
When using, it is now in such as Fig. 1 or the state such as Fig. 2, that is, fixing plate face 1 and activity plate face 8 and overlapping, now needs
Activity plate face 8 is moved to the state concordant with fixed plate face 1, by applying lateral movement power, two transverse directions to activity plate face 8
Travel mechanism is slid laterally by universal wheel 12 and directive wheel 14, while two transverse moving mechanisms are slided, is driven
Vertical misalignment mechanism is moved, and while vertical misalignment mechanism moves, its corresponding directive wheel 14 is slided in straight rail 4 respectively,
When directive wheel 14 in Dai Liangge vertical misalignments mechanism moves to the position of arc skew guide rail 5 in straight rail 4, respectively enter
To in corresponding arc skew guide rail 5, in this motion process, there is certain twisting resistance for transverse moving mechanism, laterally move
Motivation structure is made transverse moving mechanism that certain deformation occurs by the steering-effecting of universal wheel 12 and coordinates two 14 points of directive wheels
Do not enter into smoothly in arc skew guide rail 5.Now, the coplanar of fixed plate face 1 and activity plate face 8 is completed.Then if desired
Fixed plate face 1 and activity plate face 8 are overlapped, exposes the space after activity plate face 8, during for functions such as multimedia teaching, together
Sample applies lateral movement power to activity plate face 8, and two transverse moving mechanisms carry out horizontal cunning by universal wheel 12 and directive wheel 14
It is dynamic, while two transverse moving mechanisms are slided, the movement of vertical misalignment mechanism is driven, while vertical misalignment mechanism moves,
Directive wheel 14 is slided in arc skew guide rail 5, and the directive wheel 14 in Dai Liangge vertical misalignments mechanism is in arc skew guide rail 5
When moving to the position of straight rail 4, activity plate face 8 progressively avoids fixing the position of plate face 1, so as to smoothly move to and fixation
The state that plate face 1 is overlapped, in this steering procedure, has certain twisting resistance for transverse moving mechanism, and transverse moving mechanism leads to
The deformation for crossing the steering of universal wheel 12 to make transverse moving mechanism generation certain coordinates two directive wheels 14 smoothly to enter into respectively
In arc skew guide rail 5.It is finally completed fixed plate face 1 and activity plate face 8 is overlapped.
The design of one fixed plate face 1 and an activity plate face 8 is the elementary cell of blackboard design, if desired larger book
When writing plate face, the design of existing Push-pull blackboard is copied, two above-mentioned elementary cells are arranged symmetrically.
Above-mentioned specific embodiment cannot function as limiting the scope of the invention, for the technology people of the art
For member, any alternate modification or conversion made to embodiment of the present invention are all fallen within protection scope of the present invention.
The present invention does not describe part in detail, is the known technology of those skilled in the art of the present technique.
