A first pressing plate 205 for pressing the drawings is arranged above the second base 6. By setting the multi-section telescopic rod 201, the second base 6 can be pulled away from the first base 5 by manual force, driving the multiple groups of multi-section telescopic rods 201 to stretch, thereby displaying the drawings inside the winding drum 1 on one side of the multi-section telescopic rod 201. When winding, the multi-section telescopic rod 201 is contracted, and the control knob 207 is adjusted to wind the drawings through the winding drum 1.

[0035] The top of the second base 6 is fixedly connected with an L-shaped piece 206, the top of the L-shaped piece 206 is threadedly connected with a first threaded rod 204, one end of the first threaded rod 204 is fixedly connected with a first adjusting knob 203, the other end of the first threaded rod 204 is rotatably connected to the top of the first pressing plate 205, the top of the first pressing plate 205 is fixedly connected with two groups of first springs 202, the other ends of the two groups of first springs 202 are fixedly connected to the inside of the L-shaped piece 206, the L-shaped piece 206 and the second base 6 are both movably plugged into the inside of the first base 5, and the bottom of the winding drum 1 is fixedly connected to the first pressing plate 205. A discharge port 7 is provided in the part, and a guide member 8 is fixedly connected to the bottom of the discharge port 7. The winding drum can open the inside, and a clamping assembly for fixing the drawing in the winding drum 1 is provided inside the winding drum 1. The clamping assembly is a prior art and is not introduced in detail here. By setting a first adjusting knob 203, the first threaded rod 204 can be rotated by turning the first knob, and the first pressure plate 205 can be driven to move, so that one end of the drawing is stably pressed under the pressure plate, and the elastic potential energy is released by setting a first spring 202 to improve the stability of the pressing of the two ends of the first pressure plate 205.

[0037] Embodiment 2

[0038] See also Figure 1 - Fig. 9 The present invention provides a technical solution: a drawing rolling device for art design. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. A protective mechanism 3 is provided on one side of the first base 5 for protecting the drawing during the unfolding process.

[0039] As a further limitation of the protection mechanism 3 of the present invention, the protection mechanism 3 includes an elastic member 308, multiple groups of elastic members 308 are fixedly connected to the outer surface of the multi-section telescopic rod 201, one end of the multiple groups of elastic members 308 is fixedly connected to a limiting member 3010, the bottom of the multiple groups of elastic members 308 is fixedly connected with a protrusion 3011, and a chamfer 3014 is provided at a corner of the protrusion 3011. By setting the limiting member 3010, the limiting member 3010 makes the moving rod inside the multi-section telescopic rod 201 unable to move. By setting the protrusion 3011, when the protrusion 3011 moves, the elastic member 308 can be bent, and the limiting member 3010 can be driven to move, so that the limiting member 3010 releases the limit on the moving rod.

[0040] A movable groove 309 is provided inside each of the multiple groups of multi-section telescopic rods 201, and a through hole 3012 is provided above the movable groove 309 and penetrates the outer surface of the multi-section telescopic rod 201. The protrusion 3011 is movably inserted into the inside of the through hole 3012. Through the setting of the through hole 3012, the protrusion 3011 can be movably inserted into the inside of the multi-section telescopic rod 201.

[0041] The multiple groups of multi-section telescopic rods 201 are composed of multiple groups of moving rods with different diameters. The internal moving rods of the multiple groups of multi-section telescopic rods 201 are fixedly connected to multiple groups of moving parts 3013. The multiple groups of moving parts 3013 are slidably connected to the inside of the moving groove 309. By setting the moving parts 3013, when the moving rods move, the moving parts 3013 can be driven to move inside the moving groove 309. The moving parts 3013 squeeze the chamfers 3014 opened by the protrusions 3011 to move the protrusions 3011. Only when one group of moving rods is completely moved into place, will the protrusions 3011 be squeezed to release the restriction of the limiter 3010, and then the next group of moving rods will start to move.

[0042] The outer surfaces of the moving rods of the multiple groups of multi-section telescopic rods 201 are fixedly connected with connecting pieces 307. The internal diameters of the multiple groups of connecting pieces 307 are different. They are fixedly connected to the outer surfaces of the moving rods with different diameters. The outer surfaces of the connecting pieces 307 are fixedly connected with U-shaped pieces 305. The tops of the multiple groups of U-shaped pieces 305 are in a plane. A sliding groove 304 is penetrated through the top of the U-shaped pieces 305. The sliding groove 304 is slidably connected with a slider 303. The U-shaped piece 305 can be movably placed inside the first base 5. By setting the slider 303, the slider 303 can be moved inside the sliding groove 304 to adjust the position of the slider 303. When the second base 6 moves to the inside of the first base 5, all the U-shaped pieces 305 are also moved to the inside of the first base 5.

[0043] The top of the slider 303 is threadedly connected to a second threaded rod 301, the top of the second threaded rod 301 is fixedly connected to a second adjusting knob 302, and the bottom of the second threaded rod 301 is fixedly connected to a second pressure plate 306. Through the setting of the second adjusting knob 302, the second adjusting knob 302 can be rotated to drive the second threaded rod 301 to rotate, drive the second pressure plate 306 to move, and fix the drawing in the U-shaped member 305 through the second pressure plate 306.

[0044] The specific implementation of this embodiment is as follows: by applying force manually, the multi-section telescopic rod 201 is pulled to stretch, the moving rod is driven to move inside the multi-section telescopic rod 201, and the moving member 3013 is driven to move in the moving groove 309. When the moving member 3013 moves to the end of the moving groove 309, the moving member 3013 squeezes the chamfer 3014 provided by the protrusion 3011, so that the protrusion 3011 moves, thereby causing the elastic member 308 to bend, driving the limit member 3010 to move, so that the limit member 3010 releases the limit on the moving rod, so that the next group of moving rods can start to move. Therefore, only after the previous group of moving rods cannot move, the next group of moving rods starts to move. When the moving rods move and drive the U-shaped member 305 to move By turning the second adjusting knob 302, the second threaded rod 301 is driven to rotate, and the second pressing plate 306 is driven to move. The drawing is fixed in the U-shaped member 305 through the second pressing plate 306, so that the drawing has multiple fixing points. When the drawing is pulled out, it is no longer the entire drawing that is subjected to force, but it is divided into parts, which greatly reduces the probability of damage to the drawing. Through the setting of the slider 303, the slider 303 can be moved inside the sliding groove 304, and the connecting member 307 can be selected to be fixedly connected to the outer surface of different multi-section telescopic rods 201. The position of the slider 303 can be adjusted later to adapt to drawings of different widths, and art design drawings of different widths can be rolled up and displayed through the device.

[0045] Embodiment 3

[0046] See also Figure 1 - Fig. 9 The present invention provides a technical solution: a drawing rolling device for art design. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. Two sets of placing mechanisms 4 for standing up the drawings are provided on the other side of the first base 5.

[0047] As a further limitation of the placement mechanism 4 of the present invention, the two groups of placement mechanisms 4 both include a first shell 402, wherein one group of the first shells 402 is fixedly connected to the bottom of the first base 5, the other group of the first shells 402 is fixedly connected to the bottom of the second base 6, and the other group of the first shells 402 can be movably placed inside the first base 5, and the interiors of the two groups of the first shells 402 are both movably plugged with a card 4010. By setting the card 4010, the card 4010 can be fixed in the first shell 402, thereby fixing the pillar 401 to one side of the first base 5 and the second base 6.

[0048] One side of the two groups of first shells 402 is fixedly connected to the second shell 403, the interior of the second shell 403 is slidably connected to the moving plate 407, one side of the moving plate 407 is fixedly connected to the pull rod 405, one end of the pull rod 405 passes through the second shell 403 and is fixedly connected to the pull plate 404, the outer surface of the pull rod 405 is sleeved with a second spring 406, the other side of the moving plate 407 is fixedly connected to two groups of positioning members 408, one side of the clamping member 4010 is provided with two groups of positioning holes 409, one end of the positioning member 408 passes through the first shell 402 and is movably plugged into the positioning hole 409. 9, by setting a pull plate 404, the pull plate 404 can be pulled to drive the pull rod 405 to move, drive the moving plate 407 to move, compress the second spring 406, and at the same time drive the positioning member 408 to move, so that one end of the positioning member 408 is away from the first shell 402, and then the clamping member 4010 is placed in the first shell 402. After letting go, the second spring 406 releases elastic potential energy, drives the moving plate 407 to move, drives the positioning member 408 to move, and drives the positioning member 408 to insert into the positioning hole 409, thereby fixing the clamping member 4010 in the first shell 402.

[0049] The bottom of the clamp 4010 is fixedly connected to the pillar 401, and the outer surface of the pillar 401 is symmetrically fixedly connected to two groups of cross bars 4013, one end of the cross bar 4013 is fixedly connected to the air pipe 4011, the bottom of the air pipe 4011 is fixedly connected to the vacuum suction cup 4014, and the top of the air pipe 4011 is detachably connected to the cap 4012. The length of the air pipe 4011 can ensure that the suction cup can be sucked on the top of the workbench. By setting the vacuum suction cup 4014 and manually squeezing the air in the vacuum suction cup 4014, the vacuum suction cup 4014 sucks the surface of the workbench, and the pillar 401 is fixed above the workbench, so that the entire drawing is erected, which can be convenient for more people to watch. When the drawing is put away, it is only necessary to turn the cap 4012 to connect the air pipe 4011 with the outside air to release the suction of the vacuum suction cup 4014.

[0050] The specific implementation of this embodiment is as follows: by pulling the pull plate 404, the pull rod 405 can be moved, the movable plate 407 can be moved, the second spring 406 can be compressed, and the positioning member 408 can be moved at the same time, so that one end of the positioning member 408 is away from the first shell 402, and then the clamp 4010 is placed in the first shell 402. After letting go, the second spring 406 releases elastic potential energy, drives the movable plate 407 to move, drives the positioning member 408 to move, and drives the positioning member 408 to insert into the positioning hole 409, so that the clamp 4010 is fixed in the first shell 402, and the air in the vacuum suction cup 4014 is squeezed manually, and the vacuum suction cup 4014 sucks the surface of the workbench, and the pillar 401 is fixed above the workbench, so that the entire drawing is erected, which can be convenient for more people to watch. When the drawing is put away, it is only necessary to turn the cap 4012 to connect the air pipe 4011 with the outside air to release the suction of the vacuum suction cup 4014.

[0051] Working principle: When in use, when rolling up the art design drawings for the first time, place the drawings on one side of the multi-section telescopic rod 201, pass one end of the drawings through the guide member 8 through the discharge port 7, and insert into the interior of the winding drum 1, and at the same time open the winding drum 1 to fix one end of the drawings at the output end of the winding drum 1. After the fixing is completed, close the winding drum 1, and the other end of the drawings can drive the first threaded rod 204 to rotate by turning the first adjusting knob 203, and drive the first pressing plate 205 to move, so that one end of the drawings is stably pressed under the pressing plate, and the elastic potential energy is released by setting the first spring 202 to improve the stability of the pressing of the two ends of the first pressing plate 205, and the second base 6 is pushed to move in the direction close to the first base by artificial force, so that the multi-section telescopic rod 201 is contracted, and at the same time the adjustment knob 203 is adjusted. The drawing is rolled up by turning the control knob 207, and the L-shaped member 206 and the second base 6 are both plugged into the inside of the first base 5. When displaying the drawing, it is only necessary to pull the second base 6 to stretch the multi-segment telescopic rod 201 to display the drawing on one side of the multi-segment telescopic rod 201, without disconnecting the connection between the drawing and the winding drum 1. The multi-segment telescopic rod 201 is configured to have multiple sections to accommodate drawings of different lengths. Multiple groups of multi-segment telescopic rods 201 are stretched to drive the moving rod to move inside the multi-segment telescopic rod 201, and drive the moving member 3013 to move in the moving groove 309. When the moving member 3013 moves to the end of the moving groove 309, the moving member 3013 squeezes the chamfer 3014 provided on the protrusion 3011, so that the protrusion 3011 moves, thereby causing the elastic member 308 to bend. The U-shaped member 305 is moved by the movement of the moving rod, and the second threaded rod 301 is rotated to rotate the second adjusting knob 302, thereby driving the second pressing plate 306 to move. The drawing is fixed in the U-shaped member 305 through the second pressing plate 306, so that the drawing has multiple fixed points. When the drawing is pulled out, the whole drawing is no longer stressed, but is divided into parts, which greatly reduces the probability of damage to the drawing. The slider 303 can be moved in the sliding groove 304 by setting the slider 303. The position of the art design drawing inside the winding drum 1 can be adapted to drawings of different widths, so that the art design drawings inside the winding drum 1 can be displayed on one side of the multi-section telescopic rod 201, which is convenient for displaying the results of art design. By pulling the pull plate 404, the pull rod 405 is moved, and the movable plate 407 is moved, the second spring 406 is compressed, and the positioning member 408 is moved at the same time, so that one end of the positioning member 408 is away from the first shell 402, and then the clamping member 4010 is placed in the first shell 402. After letting go, the second spring 406 releases elastic potential energy, drives the movable plate 407 to move, drives the positioning member 408 to move, and drives the positioning member 408 to insert into the positioning hole 409, so that the clamping member 4010 is fixed in the first shell 402, and the air in the vacuum suction cup 4014 is squeezed manually.The vacuum suction cup 4014 sucks the surface of the workbench, and fixes the support 401 above the workbench, so that the drawing stands up, which makes it easier for more people to see the results of art design. When the drawing is put away, it is only necessary to turn the cap 4012 and connect the air pipe 4011 to the outside air to release the suction of the vacuum suction cup 4014. When the drawing is displayed and rolled up, the second base 6 is manually pushed to shrink the multi-section telescopic rod 201, and the control knob 207 is adjusted to roll up the drawing through the winding drum 1.
