Description
Technical field
The present invention relates to multimedia teaching apparatus, and in particular to a kind of magnetic force position multimedia teaching curtain.
Background technology
Now, multimedia teaching is universal in various classroom teachings, for the classroom for being fitted without curtain, peace
It is still a troublesome thing to fill and fix curtain, and since holder will occupy, curtain is difficult to traditional stent-type curtain
It is close to blackboard, not only blows the Distance Shortened of student and curtain, but also the air for being easy to be flowed, best projection effect is not achieved
Fruit.
Invention content
In view of the deficiencies of the prior art, the present invention provides a kind of magnetic force position multimedia teaching curtains.
The technical solution adopted by the present invention is as follows：Outside a kind of magnetic force position multimedia teaching curtain, including curtain, magnet
Shell, pull rod, magnet, cushion rubber；It is characterized in that, the curtain is provided with the first horizontal stripe, another side is provided with elastic film, described
Elastic film is connect with the second horizontal stripe；Magnet shell is provided on first horizontal stripe and the second horizontal stripe, on the magnet shell
It is arranged fluted；The groove is provided with pull rod, and one end of the pull rod is fixed among groove, and other end is welded on knob
Together；The magnet is fixed in magnet shell, and the cushion rubber is arranged in magnet surrounding.
First horizontal stripe and it is respectively provided at least magnet two or more with the second horizontal stripe, first horizontal stripe and with second
Horizontal stripe is made of hard material.
The bottom surface of the magnet is flushed with the bottom surface of the first horizontal stripe and the second horizontal stripe, and the cushion rubber protrudes under magnet.
The cushion rubber is made of the larger flexible glue material of friction coefficient.
The pull rod can make appropriateness in groove and stir.
Using technical solution of the present invention, have the advantages that：
1, the present invention can not only fix on metal blank, can also be fixed on the nonmetallic blackboard for add iron edge strip；
2, of the invention since magnet edges are provided with the larger flexible glue circle of friction coefficient, it is fixed on energy in vertical plane
Prevent curtain slide downward；
3, the design that the elastic film that uses of the present invention is connect with horizontal stripe, it can be ensured that curtain is stretched smooth always, makes throwing
The image of shadow is integrally focused correctly, even if can make curtain overall leveling if fixed on the simultaneously metallic plate of out-of-flatness, makes projection
Image keeps clear.
Description of the drawings
Fig. 1 is the stereogram of the present invention（Facad structure is illustrated）；
Fig. 2 is the stereogram of the present invention（Backside structure is illustrated）；
In figure：10-curtains, the 11-the first horizontal stripe, the 12-the second horizontal stripe, 13-elastic films, 20-magnet shells,
21-grooves, 30-pull rods, 31-knobs, 40-magnet, 50-cushion rubbers.
Specific implementation mode
In the following, the invention will be further described in conjunction with the accompanying drawings and embodiments：As shown in Figure 1 to Figure 2, a kind of magnetic force positioning
Multimedia teaching curtain, including curtain 10, magnet shell 20, pull rod 30, magnet 40, cushion rubber 50；It is characterized in that, the curtain
10 are provided with the first horizontal stripe 11, and another side is provided with elastic film 13, and the elastic film 13 is connect with the second horizontal stripe 12；It is described
It is provided with magnet shell 20 on first horizontal stripe 11 and the second horizontal stripe 12, is arranged fluted 21 on the magnet shell 20；It is described recessed
Slot 21 is provided with pull rod 30, and one end of the pull rod 30 is fixed among groove 21, and other end welds together with knob 31；Institute
It states magnet 40 to be fixed in magnet shell 20, the cushion rubber 50 is arranged in 40 surrounding of magnet.
First horizontal stripe 11 and more than two, first horizontal stripe 11 that is respectively provided at least magnet 40 with the second horizontal stripe 12
It is made of hard material with the second horizontal stripe 12.
The bottom surface of the magnet 40 is flushed with the bottom surface of the first horizontal stripe 11 and the second horizontal stripe 12, and the cushion rubber 50 is protruded in magnetic
Under iron 40.
The cushion rubber 50 is made of the larger flexible glue material of friction coefficient.
The pull rod 30 can make appropriateness in groove 21 and stir.
The present invention can not only fix on metal blank, can also be fixed on the nonmetallic blackboard for add iron edge strip；
Since magnet edges are provided with the larger flexible glue circle of friction coefficient, being fixed in vertical plane can prevent the present invention
Curtain slide downward；The design that the elastic film that the present invention uses is connect with horizontal stripe, it can be ensured that curtain is stretched smooth always, makes
The image of projection is integrally focused correctly, even if can make curtain overall leveling if fixed on the simultaneously metallic plate of out-of-flatness, makes projection
Image keep clear.
The above embodiment of the present invention is cited to illustrate the invention exemplary embodiment, rather than to the present invention's
It is limited made by embodiment.The apparent variation pattern amplified out by the prompt of the embodiment of the present invention is still in the present invention's
In rights protection scope.
