Example three:

please refer to fig. 10, further including base 36, base 36's inside is provided with adjustment motor 37, riser 17 fixed mounting is at adjustment motor 37's output shaft top, riser 17's top still is provided with sunlight tracker 38, sunlight tracker 38's output and adjustment motor 37's input electric connection, four frameworks are when having the environment of sunshine direct projection to show, sunlight tracker 38 at riser 17 top can the real-time detection sunlight shine, and control adjustment motor 37 operation makes riser 17 rotatory, riser 17 is rotatory to drive four frameworks rotatory, thereby can make four frameworks's standing groove 2 all back to sunshine, prevent that sunshine direct projection from causing the damage to the drawing paper, effectual protection to the drawing paper, also be convenient for adjust the show angle simultaneously.

The working principle and the using process of the invention are as follows:

the drawing paper is placed in the placing groove 2 of the display frame 1, the two sides of the drawing paper are clamped and fixed on the side plates 3 by the magnetic blocks and the magnetic sheets 4, and the middle part of the drawing paper is in a suspended state; the temperature and the humidity in the placing groove 2 can be detected through the temperature and humidity sensor 6, when the humidity in the placing groove 2 is too high or too low, the temperature and humidity sensor 6 transmits signals to the controller, and the controller controls the heating wire 7 to generate heat, so that dehumidification and heating are performed, a storage environment suitable for the temperature and the humidity of the drawing paper is ensured, and the drawing paper is prevented from being affected with damp, damaged and mildewed;

the fan 10 operates to supply air from the bottom of the mounting cavity 9, and supply air from the air groove 8, and the air discharged from the air groove 8 is blown on the drawing paper, so that the circulation of the air on the surface of the drawing paper can be ensured, the drawing paper can be stored for a long time, and the deterioration of the drawing paper can be prevented;

the bottom of the installation cavity 9 is communicated with the storage box 13, the remote lemongrass is stored in the storage box 13, when the fan 10 runs wind, the wind flows through the storage box 13, the fragrance of the remote lemongrass is brought, the wind with the fragrance of the remote lemongrass blows the drawing paper, and the moth on the drawing paper can be killed by the fragrance, so that the drawing paper is prevented from being damaged by the moth;

the two sides of the drawing paper are clamped and fixed on the side plates 3 by the magnetic blocks and the magnetic sheets 4, the middle part of the drawing paper is in a suspension state, the middle part of the drawing paper in the suspension state is supported by the arc-shaped supporting rod 16, the arc-shaped supporting rod 16 is fixed on the inner bottom wall of the placing groove 2 through the elastic thin rod 15, when the wind of the fan 10 blows on the drawing paper, the middle part of the drawing paper blown by the wind will be sunken inwards and push the elastic thin rod 15 to generate elastic deformation through the arc-shaped support rod 16, after the wind stops blowing out by the fan 10, the elastic thin rod 15 recovers the elastic deformation and generates vibration by itself, the vibration-generated elastic thin rod 15 uses the arc-shaped support rod 16 to strike the back of the drawing paper back and forth, therefore, dust piled on the surface of the drawing paper can be shot, mould spores in the dust are prevented from germinating into hyphae, an excellent moth-proof effect is achieved, and meanwhile, the display effect of the drawing paper without dust is more vivid;

the stepping motor 19 operates to drive the fixed shaft 20 at the top of the output shaft of the stepping motor to rotate, the fixed shaft 20 rotates to drive the left end of the first frame body 101 to rotate, the left end of the first frame body 101 rotates to pull the second frame body 102 to rotate through the L-shaped connecting piece 21, and the first frame body 101 and the second frame body 102 can be folded in a V shape;

when the second frame 102 is folded in a V shape, the first connecting seat 22 and the first rotating shaft 24 can drive the driving wheel 27 to rotate, the driving wheel 27 rotates to drive the driven wheel 28 engaged with the outer wall of the driving wheel 27 to rotate, the driven wheel 28 rotates to drive the second rotating shaft 25 and the second connecting seat 23 to rotate, the second connecting seat 23 rotates to drive the left end of the third frame 103 to rotate, and the second frame 102 and the third frame 103 are also folded in a V shape; when the third frame body 103 is folded in a V shape, the L-shaped connecting piece 21 is utilized to pull the fourth frame body 104 to rotate, so that the third frame body 103 and the fourth frame body 104 are also folded in a V shape, the first frame body 101, the second frame body 102, the third frame body 103 and the fourth frame body 104 are mutually folded in a V shape, so that the four frame bodies are convenient to store, convenient to store when not being displayed, and convenient to store and transport, after two adjacent frame bodies are folded, the two placing grooves 2 are mutually closed, so that the placing grooves 2 are internally provided with light-tight and cool environments, and further convenient to store drawing paper;

when four frameworks show in the environment that has sunshine to penetrate directly, the sunlight tracker 38 at riser 17 top can the irradiation of real-time detection sunlight to control adjustment motor 37 operation and make riser 17 rotatory, riser 17 is rotatory to drive four frameworks rotatory, thereby can make the standing groove 2 of four frameworks all back to sunshine, prevent that sunshine from penetrating directly and causing the damage to the drawing paper, effectually protect the drawing paper, also be convenient for simultaneously adjust the show angle.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
