Description

Multifunction folding magnetic teaching aid

The utility model belongs to the combined teaching method apparatus.

Be used to impart knowledge to students normally blackboard and present white magnetic porcelain plate, this kind plate face has its certain superiority in indoor instruction, and in outdoor teaching because its volume is big, be difficult for moving it and use certain degree of difficulty is just arranged.

The purpose of this utility model provides a kind of carrying, the activity magnetic teaching aid of being convenient to install and remove.

A kind of multifunction folding magnetic teaching aid, it is characterized in that snap close [10] being arranged by the front, there is the case lid [8] that one group of folding H type supporting leg [9] that can be connected with the case lid edge is arranged in the chest of separate type discount [11] back, and the magnetic soft board [3] that case lid has the casing [7] of a pair of strut [5] that is connected with the casing edge by self-locking butterfly hinged joint [6] in down and is hung on the band suspension ring [1] on the cross bar [2] between strut is formed.This magnetic soft board is that the permanent-magnet block [13] of separating placed adjacent opposed polarity in the pouch of making between the two layers of cloth of band layback band [4] forms, and the outer periphery of two layers of cloth studs with the multiple again calico [4] that velcro is arranged with periphery in velcro limit [12].

The utility model has the advantages that use, easy to make, be easy to carry, take care of, be applicable to the multiple teaching in indoor and outdoor, to the decomposition of technical course magnetic module, combined demonstration, military training, projection teaching of culture.Case is interior and can place other teaching aids etc.

As long as case lid is taken off, strut H type supporting leg and promptly can be used as the desk use during use, the strut in the casing is opened, and connects cross bar up and down, and hanging up the magnetic soft board can use.

Accompanying drawing 1 is a multifunction folding magnetic teaching aid synoptic diagram, and Fig. 2 is that casing is opened synoptic diagram, and Fig. 3 is that synoptic diagram cuts open in magnetic soft board office, and Fig. 4 case lid is opened synoptic diagram, chest constitutional diagram when Fig. 5 case lid is opened, 1-suspension ring wherein, 2-cross bar, 3-magnetic soft board, 4-layback band, 5-strut, 6-self-locking butterfly hinged joint, 7-casing, 8-case lid, 9-folding leg, 10-snap close, 11-separate type hinged joint, 12-velcro, 13-permanent-magnet block, 14-calico.

When the utility model is executed, nail is made a rectangle wooden case earlier, after the centre is cut, or case lid and casing, and outside case, load onto latching system, the separate type hinged joint is loaded onto at the rear portion, the strut that with self-locking butterfly hinged joint steel pipe etc. is made in the casing is attached thereto, one group of folding H type supporting leg of case lid internal fixation, and other makes with two layers of cloth and is separated into a plurality of pouches, the permanent-magnet block of placed adjacent opposed polarity in the bag, the layback band of bracelet is made on the cloth both sides, and periphery is made velcro, and suspension ring are sewed in the top, other makes two peripheral band velcros and the calico identical size of two cloth, and button gets final product thereon.
