Specific embodiment
Structure depicted in Figure of description, ratio, size etc., only to cooperate the revealed content of specification, with
Understand for those skilled in the art and read, is not intended to limit the utility model enforceable qualifications, therefore does not have skill
Essential meaning in art, the modification of any structure, the change of proportionate relationship or the adjustment of size are not influencing the utility model institute
Under the effect of capable of generating and the purpose that can reach, it should all still fall in what the revealed technology contents of the utility model can be covered
In range.Meanwhile cited such as "upper", "lower", "front", "rear", " centre " term in this specification, it is merely convenient to chat
That states is illustrated, rather than to limit the enforceable range of the utility model, relativeness is altered or modified, without substantive change
Under more technology contents, when being also considered as the enforceable scope of the utility model.
A kind of mathematical education as shown in Figure 1 to Figure 3 is with board mount is shown, including pedestal 1, the frame being fixed on pedestal 1
Bar group, two side levers 3 and multiple display boards 4.
As shown in Figure 1 to Figure 2, the hack lever group includes longitudinal vertical, 21, first crossbar 22 and second crossbar 23.It is described vertical
It is connected on pedestal 1 to the lower end (screw thread) of upright bar 21, upper end connects the first crossbar 22.The first crossbar 22 is along level
Extend forward, the free end of the first crossbar 22 connects the second crossbar 23.The second crossbar relatively described first
(can also be to the right) extends cross bar to the left along the horizontal plane.Preferably make the axial direction of the axially opposing second crossbar 23 of the first crossbar 22
Vertically, the inclination axially forward of the axially opposing first crossbar 22 of the second crossbar 23 can also be made tiltedly to extend.Longitudinal upright bar 21
And two cross bar (22,23) can be an integral molding structure.
As shown in Figure 1, the side lever 3 is disposed to extend along the vertical direction, lower end is fixed on the pedestal 1, and two side levers 3
It is oppositely arranged on the front side of longitudinal upright bar 21, vertical plane locating for two side levers 3 is axially opposing with the first crossbar 22
Vertically, meanwhile, the freedom of the first crossbar 22 is (preceding) to hold the front side for extending to vertical plane locating for two side levers 3, the axis extended
Thickness that is excessive, but needing to be greater than display board is not easy to length.The front side of the side lever 3, from it is upper and under distribute alternately have it is more
A permanent magnetic plate 21.The side lever 3 of free end (left end) the opposing left setting of the second crossbar 23 is extended outwardly to the left (described
When the free end of second crossbar 23 is directed toward right side and is extended, the side lever 3 that the right end of second crossbar 23 is arranged with respect to right side is to the right
Extend outwardly).I.e. the axial length of second crossbar 23 is greater than vertical (left and right to) spacing between two side levers 3.It generally will be longitudinal
Upright bar is located at the middle rear position of two side levers, and requires the left and right page of following display boards referred to relatively intermediate at this time
The central symmetry of page.
As shown in figures 1 and 3, the display board 4 includes intermediate page 41, left side page 42 and right side page 43, and left side page
42, right side page 43 can be folded to intermediate page 43.The width requirement of general left and right side page (42,43) is less than the width of intermediate page 41
Degree cannot at least be greater than the width of intermediate page 41.In the left side edge of left side page 42, the right side edge of right side page 43
On be respectively equipped with iron bar corresponding with the permanent magnetic plate 31 on the side lever 3, in this way by the opposite intermediate page of two sides page of display board
When expansion, the edge of two sides page can be adsorbed on the side lever 3 of corresponding side, and display board is fully opened, to show thereon
The content of description.When practice production, the ipsilateral the suction-combining force being set as between permanent magnetic plate 31 and iron bar is not easy too greatly, as long as guaranteeing to show
Plate reliably open and flat can be opened just.The upper end of the intermediate page 41 is equipped with hanging ring 40, and the annular distance of the hanging ring 40 can go here and there extension
In the first crossbar 22, second crossbar 23, the outer diameter of the annular distance internal diameter that is arranged on hanging ring 40 more preferably greater than cross bar.It is preferred that will
Annular distance on hanging ring 40 is set as elliptical aperture, and two tip cambered surfaces of elliptical aperture can with first crossbar 22, second crossbar 23 it is outer
Wall contact.The outer diameter of two cross bars (22,23) can be consistent, and first crossbar outer diameter can also be made to be greater than the outer diameter of second crossbar.
It, as shown in Figure 1 and Figure 2, can be in second crossbar 23 to avoid display board 4 from sliding from the free end of second crossbar 23
Free end setting shelves disk 231 keeps the free end of second crossbar 23 upwards or horizontally forward or posteriorly or anteriorly curved backward again
Folding.
As shown in figure 3, the back side of the intermediate page 41 is equipped with the first frame 44, the hack lever of first frame 44 at least divides
At the upper end-face edge of intermediate page 41 and left and right edge, (the first frame 44 is in box shape to cloth in diagram, is distributed in intermediate page 41
Upper and lower and left and right edge) at.Left side page 42, right side page 43 the back side be equipped with the second frame 45, second frame
45 hack lever is at least distributed at the upper end-face edge and left edge of left side page 42, and the hack lever of second frame 45 is at least distributed in
The upper end-face edge and right edge of right side page 43.In the left side edge of left side page 42, it is right in the right side edge of right side page 43
Iron bar set by the permanent magnetic plate 31 on side lever 3 is answered to be inlaid in the second frame 45.The second frame 45 is L-shape in diagram, iron bar
It is inlaid in longitudinal extension rod of frame.
Three pages being capable of close proximity when to guarantee that left and right side page (42,43) are folded towards intermediate page 41.As shown in figure 3,
41 upper end of the intermediate page setting permanent magnets 441 are (as shown in figure 3, the permanent magnets 441 are inlaid in the upper end of the first frame 44
In hack lever), the iron plate 46 of the corresponding permanent magnets 441 of setting in the left and right side page (42,43) upper end.Iron plate length wants small
In 1/2 (length refers to the left and right under Fig. 3 displaying to size) of 441 length of permanent magnets.It also requires that between permanent magnets and iron plate
The suction-combining force should not be excessive.
Above embodiment is only illustrative of the principle and efficacy of the utility model, and not for limitation, this is practical new
Type.The utility model can be improved there are many more aspect under the premise of without prejudice to overall thought, for being familiar with this technology
Personage can all be carried out modifications and changes to above-described embodiment under the spirit and scope without prejudice to the utility model.Therefore,
Such as those of ordinary skill in the art is in spirit revealed without departing from the utility model and institute under technical idea
All equivalent modifications or change completed, should be covered by the claim of the utility model.
