Abstract

The utility model provides a chart hanging clip in classroom, which is an improved chart hanging clip. The chart hanging clip is suitable for hanging teaching hanging charts on a blackboard. The clipping head of the clip can clip charts, and a bend hook arranged on the clipping tail can be hung on the upper edge frame of the blackboard and can move right and left along the frames of the blackboard, so that the chart hanging clip brings convenience for teachers in using hanging charts in a class, and overcomes the defects that nails used to hang charts damage wall surface and hanging charts are inconveniently to be moved.

Description

Hanging chart clip in classroom

The utility model relates to a kind of small-sized elastic force clip, particularly a kind of clip that can be used to hang school wall map on blackboard.Be suitable for using when the teacher upward hangs school wall map class hour on blackboard.

Utilizing wall chart to carry out classroom instruction is the conventional means that many courses are given lessons.The method that tradition hangs wall chart generally is first pounding iron nail on the wall above the blackboard, then wall chart is fixed cotton rope and hangs on the iron nail later on.This method has following shortcoming: 1, pound nail and destroy wall, influence attractive in appearance.2, when iron nail was pounded in blackboard one side, wall chart was too far away apart from writing on the blackboard, explanation inconvenience; When iron nail was pounded above blackboard, then wall chart covered the part blackboard, and influence is write.For mobile wall chart, improve the utilization rate of blackboard, the phenomenon that common blackboard top has a row to pound several nails occurs, and this obviously is unavoidable thing.

The utility model is exactly that a kind of Clamp for hanging chart that forms that improves on little iron clamp basis will be provided, and it has the effect on the upper side frame that under the situation of not using iron nail wall chart is suspended on blackboard.

The utility model is to be basic structure with common little iron clamp, the afterbody design of one side grip is gone up hook formation forms.

The utility model is simple in structure, novel, cheap, can both use on all blackboards that has a frame, has not only avoided pounding the problem of nail on wall, and can make wall chart carry out move left and right neatly along blackboard, uses very convenient.This kind Clamp for hanging chart has been arranged, also very convenient when needing on blackboard, to hang multiple hanging chart simultaneously.

Concrete structure of the present utility model is provided by drawings and Examples.

Fig. 1 utilizes the utility model to hang the schematic perspective view of wall chart on blackboard.Fig. 2 is the side schematic view of Fig. 1.

Fig. 3, Fig. 4 and Fig. 2 are basic identical, expression be situation when after opening a groove on the upper side frame at blackboard or tumbling in a little batten, hanging wall chart with nail.

A kind of clip that is analogous to little iron clamp, particularly a kind of clip that is used for hanging wall chart on blackboard is compared with common little iron clamp, it is characterized in that the afterbody of clamp one side grip ［ 2 ］ has the structure of crotch ［ 3 ］.

Claims

Fig. 5 is the schematic perspective view of the Clamp for hanging chart that designs on the little iron clamp basis that another is made by steel disc, steel bar.

With reference to Fig. 1, Fig. 2, it is identical with common little iron clamp that Clamp for hanging chart [4] produces the structure and the principle of folder power, just during fabrication a side grip [2] extended, and elongated portion is bent to hook formation [3].

During use, clamp wall chart [6] with the chuck [5] of Clamp for hanging chart, the upper side frame [1] that again crotch [3] is hung over blackboard upward gets final product.On the upper side frame of blackboard, open a groove [7] or tumble in a little batten [9] Fig. 3, Fig. 4 if resemble, then can further strengthen suspension with little iron nail [8].

What deserves to be mentioned is that the little iron clamp of being made up of elastic steel sheet and steel bar as shown in Figure 5 is after extend a side grip and hook structure [10], its practical effect is identical with Clamp for hanging chart among Fig. 1.
