Abstract
The utility model discloses a double-sided automatic suction built-in strong magnetic core transparent card cover which can display teaching cards/pictures on blackboards/white boards/green boards and other iron materials by utilizing magnetic adsorption. Small holes are formed on a three-layer binding body consisting of a two-layer laminated transparent film and an isolated layer filler strip clamped between the closed edges in equal distance; the strong magnetic cores of which the shapes and sizes are meshed with those of the holes are inlaid in the holes; each strong magnetic core is made of a strongly magnetic material with high neodymium iron boron magnetic performance; an edge is formed on the outer side so as to fix and cover the built-in strong magnetic cores; and an elliptical notch is formed at the opening of the two-layer transparent film. According to the special card cover, the teaching cards/pictures can be conveniently inserted or taken out, the single-sided adsorption display or double-sided free turning adsorption display of the teaching cards/pictures in the card cover on the blackboards/white boards/green boards can be conveniently realized by utilizing the extremely high attraction force of the strong magnetic cores in the closed edge. The double-sided automatic suction built-in strong magnetic core transparent card cover is easy, convenient and quick to use and operate; and the card cover is simple in manufacturing process and low in cost.
Description
Technical field
The utility model relates to a kind of stationery, especially utilizes magnetic force to show the transparent card cover of the built-in strong magnetic core of two-sided automatic suction of teaching card/picture in blackboard/blank/irony panels such as green plate absorption.
Background technology
At present, knownly utilize magnetic force absorption to show that the way of teaching card/picture has products such as common magnetic, strong magnetic magnetic, rubber magnet at ferrous materials such as blackboard/blank/green plates.Common magnetic, strong magnetic magnetic be owing to separate with teaching card/picture, adsorbs or troublesome poeration when overturning its positive and negative content, wastes time and energy.Use the card cover of rubber magnet, can only show the single face content, if operation is also pretty troublesome will overturn its positive and negative content the time.
Summary of the invention
In order to overcome existing common magnetic (ferrite) magnetic, strong magnetic (neodymium iron boron) magnetic is troublesome poeration when absorption teaching card/picture, the shortcoming that wastes time and energy, and the utility model provides the built-in strong magnetic core of a kind of two-sided automatic suction transparent card cover.The transparent card cover of this special built-in strong magnetic core can easily insert or take out and need adsorb teaching card/picture of showing, and the while can be utilized to cover in enclosed edge and realize easily that along the high magnetic attracting force of the strong magnetic core in the bound edge single face of teaching card/picture on blackboard/blank/green plate in the card cover adsorbs displaying or the two-sided absorption displaying of freely overturning.
The technical scheme that its technical problem that solves the utility model adopts is: the transparent card cover of the built-in strong magnetic core of two-sided automatic suction, by corresponding to two stacked transparent films of putting of card/dimension of picture size and enclosed edge along among sandwich form every the dead level filler strip with card thickness is suitable mutually, on the three-layered node zoarium on this enclosed edge edge, equidistantly have aperture, the built-in big or small strong magnetic core that coincide with the hole of shape that is inlaid with in the hole, strong magnetic core is to be made by the high ferromagnetic material of neodymium iron boron class magnetic force performance, has the U-shaped bound edge to help to fix and cover built-in strong magnetic core in its outside.Interposition at the opening port of the two stacked transparent films of putting that can insert teaching card/picture is equipped with oval breach, to make things convenient for teaching card/picture to insert or to take out.
The beneficial effects of the utility model are, built-in strong magnetic core is combined perfect with the three-layered node zoarium at the edge of transparent card cover sealing, add special oval breach, common teaching card/picture can be inserted or take out easily, and the while can be utilized to cover in enclosed edge and realize easily that along the high magnetic attracting force of the built-in strong magnetic core of inlaying in the equidistant aperture on the three-layered node zoarium in the bound edge single face of teaching card/picture on blackboard/blank/green plate in the card cover adsorbs displaying or the two-sided absorption displaying of freely overturning.Simple, convenient, quick.Card cover manufacture craft is simple, cost is low.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is that the enclosed edge of card cover in the technical solutions of the utility model is along the vertical section structural map;
Fig. 2 is single opening port of card cover in the technical solutions of the utility model and two kinds of planar configuration figure of two opening ports;
The specific embodiment
Card cover in embodiment illustrated in fig. 1, edge in sealing, the two stacked transparent films of putting (1) and middle sandwich on the three-layered node zoarium of dead level filler strip (2), equidistantly have an aperture (3), the built-in strong magnetic core (4) that is inlaid with in the hole, outside have U-shaped bound edge (5) to help fixing and cover built-in strong magnetic core.
Card cover in embodiment illustrated in fig. 2, in enclosed edge along the built-in strong magnetic core (4) that is inlaid with in the aperture that equidistantly has on the three-layered node zoarium (3), there is U-shaped bound edge (5) outside, and the interposition of the two stacked transparent film of putting (1) opening ports is equipped with oval breach (6).
Claims (6)
1. the transparent card cover of the built-in strong magnetic core of two-sided automatic suction comprises transparent film, every the dead level filler strip, and equidistant aperture, strong magnetic core, bound edge, oval breach is characterized in that: built-inly in the aperture on the three-layered node zoarium on enclosed edge edge be inlaid with strong magnetic core.
2. the transparent card cover of the built-in strong magnetic core of two-sided automatic suction according to claim 1 is characterized in that: equidistantly have aperture by what the two stacked transparent films of putting and enclosed edge sandwiched along the centre above the three-layered node zoarium that the dead level filler strip is formed.
3. the transparent card cover of the built-in strong magnetic core of two-sided automatic suction according to claim 1 is characterized in that: the built-in big or small strong magnetic core that coincide with aperture of shape that is inlaid with in the equidistant aperture on the three-layered node zoarium on enclosed edge edge.
