Embodiment 1

[0020] Embodiment one, as figure 1 As shown, the flipchart device used in conjunction with the blackboard includes a flipchart frame 1, such as figure 2 As shown, the vertical section of the wall chart frame 1 is an inverted concave structure, and the wall chart frame 1 can be made of insulating plastic material. The two ends of the wall chart frame 1 are respectively connected to the left and right sides of the blackboard, and the wall chart frame 1 can slide up and down along the blackboard to form a sliding connection structure between the wall chart frame 1 and the blackboard. Set the wall chart frame 1 to slide up and down along the blackboard. When you don’t need to use the wall chart frame 1, you can slide the wall chart frame 1 to the top or bottom of the blackboard so that the wall chart frame 1 does not affect the normal use of the blackboard. When you need a wall chart , the wall chart frame 1 can be slid up and down according to viewing needs, thereby adjusting t...

Embodiment 2

[0023] Embodiment 2. On the basis of the foregoing embodiments, further, the clamping structure is an electromagnet 4 respectively fixed on the sides of the two splints 3, and the positions of the two electromagnets 4 are correspondingly arranged. After the iron 4 is energized, it attracts each other to form a structure for fixing the drawings.

[0024] Wherein, the two electromagnets 4 are connected in series and are connected with an external power supply through a power line. Wherein, the electromagnets 4 all adopt the prior art. After the two electromagnets 4 are energized, they generate magnetism. After the two electromagnets 4 generate magnetism, they can be attracted together by magnetic phase.

[0025] Among them, such as image 3 As shown, a groove 5 is provided on the sides of the two splints 3 close to each other, the electromagnet 4 is embedded in the groove 5, and the electromagnet 4 is bonded inside the groove 5 by glue. Wherein, the groove 5 can adopt a rectan...

Embodiment 3

[0028] Embodiment 3. On the basis of the above-mentioned embodiments, further, the left and right sides of the blackboard are fixed with chutes 7, wherein the chutes 7 can be fixed on the left and right sides of the blackboard by screws, or can be fixed on the blackboard by welding. left and right sides. Both sides of described wall chart frame 1 are connected with sliding wheel 8, and wherein, chute 7 and sliding wheel 8 are similar to the structure of chute and sliding wheel in the sliding cabinet door in the prior art, for example model is W628 morning sliding wheel, sliding wheel 8 can be fixed on both sides of the wall chart frame 1 by screws.

[0029] Such as image 3 and 4 As shown, the sliding wheel 8 can be connected in the chute 7, and can be adapted to slide up and down with the chute 7, and the chute 7 is provided with a The positioning structure 9 that slides on 7. Among them, such as Figure 5 As shown, the internal structure of the positioning structure 9 i...

Abstract

The invention discloses a wall map device used in cooperation with a blackboard, and relates to the technical field of teaching appliances. The wall map device comprises a wall map frame, wherein thetwo ends of the wall map frame are connected to the left side and the right side end of the blackboard respectively, and the wall map frame can slide up and down along the blackboard; both side surfaces of the interior of the wall map frame are connected with clamping plates through a plurality of springs; and a clamping structure is arranged between the two clamping plates, and the clamping structure can fix a drawing to the interior of the wall map frame. According to the wall map device used in cooperation with the blackboard provided by the invention, the device is reasonable in design andsimple in structure, the drawing is fixed on the blackboard through the principle of an electromagnet, the operation is simple and convenient, and meanwhile, the drawing is not easy to damage, the drawing can be reused, the labor intensity of a teacher is reduced, and the teaching efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of teaching tools, in particular to a wall chart device used in conjunction with a blackboard. Background technique [0002] In the process of history teaching, it is often necessary to use drawings to assist the course. At present, teachers usually use tape to fix the drawings on the blackboard. When changing the drawings, they need to tear off the drawings on the blackboard or stick them on the previous drawings. The operation is very difficult. It is troublesome, and the drawings cannot be reused, resulting in a waste of resources. At the same time, it will cause damage to the blackboard surface and affect the use of the blackboard. There are also teachers who use hooks to hang the drawings on the blackboard, but they need to set hook holes on the drawings. Some drawings are more Thin, the drawing is easily damaged from the hook hole during hanging. Contents of the invention [0003] In view of the abo...
