The use state of the present invention is that before use, the support rods 4 on the left and right sides are in a contracted state under the action of the telescopic mechanism, that is, the two fixing blocks 22 sleeved on each support rod 4 are respectively located on the support rods 4 The front and rear ends of the front and rear ends are further hinged to each other through the connecting rods 21, so that the distance between two adjacent support rods 4 is in a small state, and the distance between the rotating shaft and the telescopic rod is also small, so that the whole is relatively compact; at the same time The left and right first rotating shafts 3 are in a rotatable state, that is, the locking screws have not yet been locked. At this time, the left and right first rotating shafts 3 rotate until a plurality of support rods 4 are in a horizontal state, forming the support rods 4 on the left and right sides. The effect on tablet 1. Therefore, the height of the whole device is only about two thicknesses of the flat plates 1 .

At this time, the sleeve 5 is not sleeved on the end of the support rod 4. At the same time, because the sleeve 5 and the cylinder 6 are clamped through the raised block 23, the sleeve 5 can move back and forth along the cylinder 6, and the sleeve 5 can be moved forward and backward. The barrel 5 is separated from the cylinder 6, so the sleeve 5 and the cylinder 6 are also in a disengaged state at this time. The second rotating shaft 7 in the cylinder 6 is wound with drawings that need to be displayed in advance, and the drawings will be placed on the second shaft. Under the action of the torsion spring 8 on the rotating shaft 7, the state of being wound on the second rotating shaft 7 is kept, so that the cylinder 6, the sleeve 5, and the flat plate 1 and the support rod 4 are in a separated state, and then the various parts and devices can be packed in a box. Well packaged, portable and easy to transport.

Further, since the spring sheet 11 is connected between the limit rod 10 and the support rod 4, and the elastic force of the spring sheet 11 is greater than the elastic force of the return spring 16, when the sleeve 5 is not sleeved on the support rod 4, at this time Spring leaf 11 can extrude stop bar 10, make a plurality of stop bar 10 be in the state of opening, can pass the effect of the first rope 15 that is connected between stop bar 10 and the first pin 14 simultaneously, make The first pin 14 is placed in the second blind hole, and does not stretch out the second blind hole, wherein the end of the support rod 4 is provided with a central hole of the axis, so that the first rope 15 can be arranged conveniently, so that the first rope 15 The limiting rod 10 and the first pin 14 can be connected through the central hole.

When it needs to be displayed, first place the tablet 1 horizontally on the ground, and properly fix the tablet 1 as needed, and then rotate the first rotating shaft 3, at this time, the support rods 4 on the left and right sides will be driven by the telescopic mechanism Rotate together next, and adjust the angle of rotation as needed. By rotating different angles and adjusting the sliding distance of the slider 2, different display effects can be achieved, such as several situations shown in Figure 1, or other display effects ; During the rotation of the first rotating shaft 3, the first rotating shaft 3 will rotate along the slider 2. At this time, since the first rotating shaft 3 is provided with a second groove 19, during the rotation, the second pin 20 Will be stuck in the second groove 19, because the strength of rotating the first rotating shaft 3 is relatively large, so the rotating shaft continues to rotate, the second pin 20 will break away from the second groove 19 again, when the first rotating shaft 3 is not rotated, the second The pin 20 will be stuck in the second groove 19, so that the position of the rotating shaft is fixed, and it will not rotate relative to the slider 2; at the same time, when the distance of the slider 2 moving left and right along the plate 1 is adjusted, the rotation lock Tighten the screw so that the lower end surface of the locking screw is in contact with the flat plate 1. At this time, the slider 2 cannot continue to slide, and the positioning of the slider 2 is realized.

After the position of the rotating shaft is fixed, the support rod 4 is stretched upwards at this time, or the telescopic mechanism is stretched, so that the distance between the support rod 4 and the support rod 4 is adjusted large, and the support rod 4 and the first rotating shaft 3 The distance between them will also be adjusted relatively large, so that the whole device is in a relatively high position. Since there is a certain friction force between the mutually hinged connecting rods 21, that is, there is a certain friction force at the hinge point, so the stretching Finally, the whole device can keep the stretched state. If the frictional force does not resist the gravity of the customer support rod 4, the auxiliary connecting rod 9 can be used to fix the telescopic mechanism, and place the telescopic mechanism to shrink.

After the position of the support rod 4 is adjusted, a sleeve 5 is respectively clamped at the front and rear ends of the cylinder 6. Since the outer edge of the sleeve 5 is provided with a raised block 23, the outer edge of the cylinder 6 There is a T-shaped groove matching with the protruding block 23 on the surface, so the protruding block 23 on the sleeve 5 can be slid in along the T-shaped groove of the cylinder 6 .

Then the sleeve 5 at the front and rear ends of the cylinder 6 is corresponding to the support rod 4, and continues to slide the sleeve 5 inwardly, and at the same time the sleeve 5 is not in contact with the stop bar 10. In the two blind holes, the first pin 14 will not be placed in the groove on the inner surface of the sleeve 5, and then the sleeve 5 will continue to rotate. The surface is square, therefore, the support rod 4 cannot rotate, and the cross-section of the part where the front and rear ends of the support rod 4 are in contact with the sleeve 5 is circular, and the support rod 4 and the sleeve 5 are clearance fit, so the sleeve 5 can be rotated.

After rotating the sleeve 5 to a suitable angle, stop rotating the sleeve 5 and continue to slide the sleeve 5 inward. At this time, the sleeve 5 will squeeze the limit rod 10 so that the limit rod 10 faces the support rod 4 At the same time, the first rope 15 will be loosened, so that the first pin 14 will move outward under the action of the return spring 16, and be stuck in the groove on the inner surface of the sleeve 5, so that the sleeve 5 cannot be rotated. , because the groove runs through the front and rear sides of the sleeve 5 , the first pin 14 can move forward and backward along the groove, so that the sleeve 5 can continue to move inward along the support rod 4 .

When the sleeve 5 continues to move inward, the first pin 14 is not moving at this time, and the stop rod 10 will be placed in the annular groove 12 of the inner edge of the sleeve 5 at the same time. At this time, under the action of the spring plate 11, the limit rod 10 will be stuck in the annular groove 12, so that the sleeve 5 cannot slide outward, and the rotation angle of the sleeve 5 and the front and rear positions of the sleeve 5 are also fixed. .

After the sleeve 5 is fixed, the connecting rod 9 hinged on the outer edge of the cylinder 6 is drawn to be perpendicular to the cylinder 6, and the drawings wound on the second rotating shaft 7 are pulled out of the cylinder 6, and the drawings are drawn out of the cylinder 6. It is fixed on the connecting rod 9 by a clip, so that the whole device presents a display mode similar to that shown in Figure 1, which is convenient for exhibition.

When not needing to exhibit, at first pull the second rope 17 that is connected on the stop rod 10, make stop rod 10 break away from annular groove 12, just can outward slide sleeve 5 this moment, when sleeve 5 moves outwards Finally, unclamp the second rope 17, now the limit rod 10 will reset under the effect of the spring leaf 11, and make the first pin 14 shrink in the second blind hole at the same time. 4 are disengaged, so that the sleeve 5, the cylinder 6, and the support rod 4 are separated again, and the support rod 4 is compressed, the drawing is withdrawn, and then each part and the device are installed in a box.

When displaying, especially for buildings similar to structures such as shopping malls, the layout of each floor is often not the same. Shrink into the cylinder 6, or rotate the layer above the layer, so that it is in the opposite direction to the layer, which is convenient for investors or consumers to watch.

The advantage of the present invention is that by setting two sets of display devices on the left and right, that is, there are rotating shafts and other mechanisms on the left and right sides, and by setting corresponding sliding and rotating, rich display effects can be achieved, and multiple identical devices can be used. The shape design shows a more stunning display and brings a visual feast to the audience.

In the present invention, the compression of the whole device is realized by connecting the support rod 4 and the rotating shaft through a telescopic mechanism. At the same time, the cylinder 6 and the support rod 4 are also in a detachable state, so that the whole device is in a contracted state. It is greatly reduced, easy to carry and transport, and at the same time, it can protect the drawings and prevent the drawings from being damaged.

The present invention considers that it is easy to disassemble, so the sleeve 5, as well as the annular groove 12, the first pin 14, the limit rod 10, the spring leaf 11, etc. are cleverly arranged at the connection between the cylinder 6 and the support rod 4, and the That is, it is convenient to adjust the display angle of the drawings, fix the drawings, and facilitate disassembly and assembly.
