Abstract

The utility model discloses a wall chart hanger used in classroom, which comprises a horizontal main rod, two end bases used for inserting with and movably matching with both ends of the main rod, a drive system for realizing forward or backward rotation of the main rod, a horizontal minor rod used for hanging teaching illustrations and two bendable soft belts; wherein, both ends of the minor rod are connected with both ends of the main rod through two soft belts; all the components are fixed or can be bundled into a vestlet which is provided with an opening at the lower lateral face and is fixed horizontally at the upper part of the blackboard. When in work, the drive system drives the main rod to rotate, so that the soft belts are folded or unfolded at the external circumference of the main rod and the minor rod hanging teaching illustration is lifted in the veslet from the lower part of the opening of the veslet or lowered from the opening of the vestlet. The utility model has an advantage of concise appearance due to the veslet.

Description

Classroom's wall chart device

Technical field:

The utility model discloses a kind of school instruction apparatus, i.e. classroom's wall chart device.

Background technology:

200720004178.9 number Chinese patent application provides a kind of classroom wall chart device, it comprises movingly horizontal mobile jib of two end seats being fixed in blackboard (end) top metope, two ends and the grafting of end seats, two soft bands, secondary bar and drive system, the two ends of mobile jib are connecting the two ends of secondary bar by two soft bands, and drive system is rotated mobile jib forward or backwards.Thereby thereby soft band is folded or launch secondary bar and rise (to the blackboard upper edge) or (after the rise again) and descend at mobile jib periphery volume, can finish the need that teaching process is satisfied in the teaching figure lifting of being fixed in secondary bar.Its weak point is the not enough ornamenting of outward appearance, and situation is more outstanding when soft band is the super thin metal band especially.

Summary of the invention:

The utility model purpose provides the succinct classroom's wall chart device of a kind of outward appearance.

Classroom's wall chart device that the utility model makes up, comprise a horizontal mobile jib, for mobile jib two ends peg graft movingly two end seats, realize the drive system that mobile jib rotates forward or backwards, the secondary bar that is used for the lodge geography teaching map, and two soft bands that can curl, wherein the mobile jib two ends are being connected the two ends of secondary bar by two soft bands; The utility model wall chart device also comprises a metope horizontal fixed above blackboard, downside has the vestlet of a generatrix direction opening, No. 200720004178.9 of finishing assembling are applied for that two end seats of described wall chart device move be loaded on vestlet (pressing close to metope one side) inwall, and make mobile jib maintenance levels between two end seats, when drive system (is also inserted the vestlet inner chamber with the end seat, micromachine and limit travel thereof as electric drive system are controlled components and parts etc. automatically) when working, soft band is promoted to the vestlet inner chamber with secondary bar from the vestlet opening, and (lodge still is positioned at below, vestlet outside in the print content of the teaching figure of secondary bar, do not influence teaching), can soft band secondary bar be fallen (teacher of convenient general height gets figure or wall chart on secondary bar) from the vestlet opening.With vestlet both ends of the surface configuration capping.

See the mixed and disorderly of more details for the observer who does not make the vestlet opening inwardly probes into, at least one end in vestlet downside opening two ends is installed tabs, blocks drive system or/and the end seat makes it not visible and sees.

After using such scheme, only figure is taken off or figure is hung up secondary bar from secondary bar when needing, just the of short duration process of (entering in the vestlet) is fallen and risen to visible secondary bar and (most) soft band (in vestlet slowly), and when promptly the utility model has risen to the blackboard middle and upper part with figure or during wall chart (except that the backguy of manual driven system or the external power line of electric drive system) each parts all have not been fixed in or have received and fold in vestlet section bar inner chamber.

The specific embodiment:

The section bar that embodiment provides with the 200730003688.x Chinese patent application is the vestlet (see figure 3), it is used for self being fixed in the trailing flank (2) thicker (intensity when the polyvinyl chloride extruded profile of common material is no less than 1.5mm thickness is enough) of blackboard (1) top wall, bottom surface is the plane and contains opening (3), the end seat can be same as the end seat (letter is shown as Fig. 2) in the existing market screen-roller, its substrate (4) is fixed in vestlet trailing flank (2) by screw, its basic core (5) cover is mobile jib (6) then, the vestlet two ends all have tabs (as Fig. 4) to insert, bob piece (7) in the tabs is wide and embedding opening (3) with vestlet opening (3), flat take the vestlet internal face that piece (8) and perpendicular paste block (9) are fixed in opening (3) both sides, the interior end seat (can attach drives structure) of vestlet is located by high plate (10), weigh down the lid (11) of piece (7) and vestlet end thereby block and not visiblely see.During wall chart, the figure head enters in the vestlet with secondary bar (12), and drawing Printing Zone (13) just are positioned at all frames of blackboard (1), as shown in Figure 6.Other is succinct from Fig. 5, Fig. 6, the visible the utility model outward appearance of Fig. 7, and only drive system outside line (14) is stayed outside the vestlet when the simplest.

(generally speaking, outer vestlet be pipe etc. all can, as long as satisfy the condition that there are width suitable opening and sufficient intensity in the side, but be good with the section bar that the 200730003688.x Chinese patent application provides.The end seat also can be same as the end seat of electric projection screen.)
