Wherein, the transparent winding film 11 can be made of POE transparent plastic, EVA transparent plastic or transparent plastic material similar to a waterproof bag of a mobile phone, and the shaft rods 12 are respectively fixed at two ends of the transparent winding film 11. Then, the two shafts 12 of the first transparent reel 7 are respectively inserted into the accommodating cavity 9 of the left support column 3 and the accommodating cavity 9 of the right support column 4 from top to bottom through the notch 10, the two shafts 12 of the second transparent reel 8 are respectively inserted into the accommodating cavity 9 of the left support column 3 and the accommodating cavity 9 of the right support column 4 from top to bottom through the notch 10, and a drawing clamping area for placing drawings is formed between the transparent winding film 11 of the first transparent reel 7 and the transparent winding film 11 of the second transparent reel 8. It should be noted that, the distance between the transparent winding films 11 is slightly larger than the thickness of the drawing, so that the drawing is effectively put in, and the drawing cannot be loose in the drawing clamping area.
In addition, in order to facilitate the replacement of the transparent winding film 11, the transparent winding film 11 and the shaft rod 12 can be fixed by adopting a cementing mode, and old glue is scraped off when the replacement is needed, and the glue is re-glued.
Furthermore, in order to facilitate rapid opening of the drawing clamping area, a notch 15 is further arranged in the middle of the upper end of the transparent winding film 11 of the second transparent winding shaft 8, the notch 15 is preferably arc-shaped, and the upper end of the drawing clamping area can be rapidly opened through the notch 15, so that the drawing can be conveniently entered.
The bottom of the accommodating cavity 9 of the left supporting column 3 and the bottom of the accommodating cavity 9 of the right supporting column 4 are respectively provided with a limiting groove matched with the bottom ends of the shaft rods 12, the number of the limiting grooves is the same as that of the shaft rods 12, and the bottom ends of the shaft rods 12 are positioned in the limiting grooves. In addition, the length of the shaft 12 is greater than the depth of the accommodating chamber 9, and when the shaft 12 is placed in the accommodating chamber 9, the upper ends of the shaft 12 protrude from the accommodating chamber 9. Based on this, winding of the transparent winding film 11 can be achieved directly by the upper end rotating shaft 12.
The number of the end covers 6 is two, and the two end covers 6 are respectively arranged at the upper ends of the left support column 3 and the right support column 4 after penetrating through the shaft lever 12 from top to bottom. It should be noted that, the upper portion of the end cover 6 is provided with a limiting hole adapted to the shaft lever 12, and the end cover 6 may pass through the shaft lever 12 through the limiting hole. Based on this, the shaft lever 12 will be limited in the support column under the action of the limiting hole of the end cover 6 and the limiting groove at the bottom of the accommodating cavity 9, thereby forming a stable drawing clamping area.
The bottom cross beam 5 is arranged below the drawing clamping area, and the bottom cross beam 5 plays a supporting role on the whole drawing showing stand. Meanwhile, since the lower end of the drawing clamping area is of an opening structure, the bottom cross beam 5 plays a role in supporting the drawing at the same time in order to prevent the drawing from falling. Specifically, the bottom cross beam 5 is in a convex structure as a whole, and the upper surface of the convex part of the bottom cross beam 5 is used as a supporting surface for supporting a drawing. The bottom cross beam 5 comprises a left beam 13 hinged with the left upright 1 and a right beam 14 hinged with the right upright 2, the left beam 13 and the right beam 14 are connected by adopting a detachable structure, the detached left beam 13 can be folded leftwards to be close to the left upright 1, and the right beam 14 can be folded rightwards to be close to the right upright 2, so that the whole volume of the drawing showing stand after contraction is smaller.
Further, a groove is formed in the end portion of the left beam 13, a protruding portion matched with the groove is formed in the end portion of the right beam 14, and the protruding portion is fixed in the groove through a pin.
It should be noted that a certain gap is formed between the lower end of the drawing clamping area and the upper surface of the bottom cross beam 5, so as to provide a space for avoiding the folding steering after the disassembly of the left beam 13 and the right beam 14, but the gap does not affect the supporting effect of the drawing.
The working principle of the utility model is as follows:
when a drawing is required to be displayed, the left upright 1 and the right upright 2 are separated to the right and left sides respectively to the proper positions, at the moment, the transparent winding films 11 on the first transparent winding shaft 7 and the second transparent winding shaft 8 are unfolded and form a drawing clamping area, the left beam 13 and the right beam 14 are fixed together through the pin shaft, the groove and the protruding part to form a support for the drawing display frame, the unfolding of the drawing display frame is completed, and finally the drawing can be placed in the drawing clamping area for teaching display. And because the left support column 3 and the right support column 4 are respectively and rotatably connected to the left upright column 1 and the right upright column 2, the left support column 3 and the right support column 4 can be simultaneously rotated to adjust the display angle of the drawing, so that detailed display, explanation and discussion of the detail part of the drawing can be conveniently carried out, and finally the teaching effect of a teacher on students in a classroom can be improved.
When the drawing is displayed, the drawing is taken out firstly, the pin shafts are loosened, the left beam 13 and the right beam 14 are respectively drawn close to the left upright 1 and the right upright 2, and finally the shaft rod 12 is rotated to wind the transparent winding film 11, the left upright 1 and the right upright 2 are drawn close, and when the left upright 1 and the right upright 2 are completely drawn close, the whole drawing display stand is contracted to the minimum volume, so that a teacher can conveniently and easily take away the drawing display stand.
