[0020] See also Figures 1 to 4 The utility model provides a technical solution: a drawing rolling and storing cylinder, comprising an outer cylinder 1, an inner cylinder 16 is slidably connected inside the outer cylinder 1, third grooves 15 are provided on both sides of the inner wall of the outer cylinder 1, a guide rod 20 is fixedly connected inside the third groove 15, a slider 21 is slidably connected on the outer side of the guide rod 20, and the side where the two sliders 21 are close to each other is fixedly connected to the inner cylinder 16, an ejection mechanism is provided on the inner wall of the outer cylinder 1 and on one side of the inner cylinder 16, a winding roller 17 is rotatably connected inside the inner cylinder 16, a fourth groove 18 is provided on the outer side of the winding roller 17, and a fixing mechanism is provided inside the winding roller 17.

[0021] The ejection mechanism includes a first spring 8, which is arranged inside the outer cylinder 1 and located on one side of the winding roller 17. One end of the first spring 8 is fixedly connected to a tray 19, and two first grooves 7 are provided on the outer side of the tray 19. A second spring 9 is provided inside the first groove 7, and one end of the second spring 9 is fixedly connected to a second clamping block 23. Two fixed blocks 5 are fixedly connected to the outer side of the outer cylinder 1. Second grooves 12 are provided in the two fixed blocks 5 and the inner side of the outer cylinder 1. A fixed plate 13 is fixedly connected inside the second groove 12. A pressing strip 6 is slidably connected between the fixing plate 13 and the inner side of the fixing block 5. A push plate 11 is fixedly connected to the outer side of the pressing strip 6 and located on one side of the fixing plate 13. A first clamping block 22 is fixedly connected to one end of the pressing strip 6 and located on the other side of the fixing plate 13. The first clamping block 22 and the push plate 11 are both slidably connected to the second groove 12. The pressing strip 6 A third spring 10 is provided on the outer side of the push plate 11 and the fixed plate 13 on the side where the push plate 11 and the fixed plate 13 are close to each other. One end of the pressing strip 6 is located on the outer side of the fixed block 5, and the first clamping block 22 is clamped with the first groove 7. By pressing the two pressing strips 6, the pressing strip 6 drives the first clamping block 22 to push the second clamping block 23 into the first groove 7, so that the first spring 8 in the compressed state can bounce the tray 19, and the bounced tray 19 will pop out the inner cylinder 16. When popping out, the slider 21 on the outer side of the inner cylinder 16 slides inside the third groove 15 on the outer side of the guide rod 20. By pressing the inner cylinder 16 into the interior of the outer cylinder 1, the tray 19 will be squeezed when pressed in, and the first spring 8 will be compressed, so that the second spring 9 will clamp the second clamping block 23 into the interior of the second groove 12 to fix the tray 19, which is conducive to popping out the inner cylinder 16 and facilitating the staff to take out the drawings.

[0022] The fixing mechanism includes a seventh groove 30, which is opened inside the winding roller 17 and located on both sides of the fourth groove 18. A fourth spring 31 is arranged inside the seventh groove 30, and a clamping block 28 is fixedly connected to one end of the fourth spring 31, and the clamping block 28 is slidably connected to the seventh groove 30. Two sixth grooves 27 are opened on the outer side of the winding roller 17, and a push block 29 is fixedly connected on the outer side of the clamping block 28 and located inside the sixth groove 27, and the push block 29 is slidably connected to the sixth groove 27. By pushing the two push blocks 29, the clamping block 28 is driven into the interior of the seventh groove 30 and the fourth spring 31 is squeezed, and one side of the drawing is inserted into the interior of the fourth groove 18. By loosening the push block 29, the compressed fourth spring 31 rebounds the clamping block 28 and fixes the drawing, which is conducive to fixing the drawing and makes it more convenient for the staff to roll the drawing on the winding roller 17.

[0023] Two connecting blocks 4 are fixedly connected to the outside of the outer cylinder 1, and a shoulder strap 3 is fixedly connected to the top of the two connecting blocks 4 for easy carrying. A connecting shaft 25 is fixedly connected to one end of the winding roller 17 and located on one side of the inner cylinder 16. A fifth groove 26 is provided on one side of the connecting shaft 25. A handle 24 is rotatably connected inside the fifth groove 26, which is convenient for staff to reel in. A cylinder cover 2 is threadedly connected to one end of the outer cylinder 1 for easy opening.

[0024] In summary, when the drawing winding and storage cylinder is used, first, the staff presses the two pressing strips 6, so that the pressing strips 6 drive the first clamping block 22 to push the second clamping block 23 into the first groove 7, so that the first spring 8 in the compressed state pops up the tray 19, and the popped-up tray 19 pops out the inner cylinder 16. When popping out, the slider 21 on the outer side of the inner cylinder 16 slides inside the third groove 15 on the outer side of the guide rod 20, and then pushes the two pushing blocks 29 to drive the clamping block 28 into the seventh groove 30 and squeeze the fourth spring 31, and insert one side of the drawing into the fourth groove 18. , by loosening the push block 29, the fourth spring 31 in the compressed state rebounds the clamping block 28 and fixes the drawing, and by turning the handle 24 out, grabbing the handle 24 and rotating it, the rotating handle 24 drives the connecting shaft 25 and the winding roller 17, thereby driving the winding roller 17 to roll up the drawing. After rolling, by turning the handle 24 back into the fifth groove 26, by pressing the inner tube 16 into the outer tube 1, the tray 19 will be squeezed when pressed in, and the first spring 8 will be compressed, so that the second spring 9 clamps the second clamping block 23 into the second groove 12 to fix the tray 19.

[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
