During carrying or transportation, the drawings lack a stable fixed structure and are prone to shaking, folding, and wrinkling. This not only affects the appearance of the drawings but may also cause key information to be obscured or damaged due to wrinkles, causing great inconvenience to engineering construction and retrieval. Therefore, a moisture-proof and wrinkle-proof storage tube for engineering drawings is proposed to solve the above problems. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 2-4This utility model provides an embodiment of a moisture-proof and wrinkle-proof storage tube for engineering drawings, comprising a tube body 1. A fixed disk 7 is fixedly connected to the lower inner wall of the tube body 1. The fixed disk 7 has a circular structure and provides stable support for the sliding of a movable block 15. A movable block 15 is slidably connected to the inner wall of the fixed disk 7. The movable block 15 can slide on the inner wall of the fixed disk 7. A buffer pad is provided at the end of the movable block 15 away from the rotating shaft 10. The buffer pad is made of elastic material to prevent the movable block 15 from squeezing and damaging the drawings. The upper side of the movable block 15 is slidably connected to the inner wall of an arc-shaped groove 16. Four movable blocks 15 are provided, and the four movable blocks 15 are evenly distributed in a ring, which can fix the drawings from four directions. A stop bar 9 is fixedly connected to the upper side of the movable block 15. The stop bar 9 moves synchronously with the movable block 15 to press against the drawings. A connecting block 14 is fixedly connected to the outer wall of the stop bar 9. The connecting block 14 serves to connect the stop bar 9 and the turntable 13. The upper side of the connecting block 14 passes through and is slidably connected to the turntable 13. On the inner wall of cylinder 3, connecting block 14 can slide within turntable 13 to ensure the stability of the abutment bar 9 during movement. A rotating shaft 10 is rotatably connected to the lower inner wall of cylinder 1. The rotation of the rotating shaft 10 drives the rotating disk 8 to rotate synchronously. The rotating disk 8 is fixedly connected to the outer wall of the rotating shaft 10, and rotates synchronously with the rotating shaft 10. An arc-shaped groove 16 is provided on the inner wall of the rotating disk 8. The arc-shaped groove 16 moves with the rotation of the rotating disk 8, causing the moving block 15 to move. Turntable 14 is rotatably connected to the inner wall of the rotating shaft 10. 3. The turntable 13 can rotate independently relative to the rotating shaft 10. The turntable 13 is configured to provide support for the sliding of the connecting block 14. A limit component is provided on the lower inner wall of the cylinder 1. The limit component is used to limit the rotating shaft 10. An extraction component is provided on the right side of the cylinder 1. The extraction component is used to extract the storage cylinder. A cylinder cover 6 is threadedly connected to the upper side of the cylinder 1. The cylinder cover 6 is tightly connected to the cylinder 1 to enhance the sealing performance. A sealing ring 11 is provided on the inner wall of the cylinder 1. The sealing ring 11 further improves the moisture-proof performance of the cylinder 1.

[0034] Reference Figure 1 and Figure 6The extraction component includes a fixing block 2, which provides a fixed fulcrum for the lifting strap 3. The fixing block 2 is fixedly connected to the right side of the cylinder 1. The lifting strap 3 is fixedly connected to the fixing block 2. The lifting strap 3 is made of wear-resistant material for easy carrying. A fixing block 4 is fixedly connected to the outer wall of the cylinder 1. A slider 19 is slidably connected to the inner wall of the fixing block 4. The slider 19 can slide up and down within the fixing block 4. A locking block 5 is elastically connected to the front inner wall of the slider 19 by a spring 18. The spring 18 provides elastic force to the locking block 5 so that it can lock the fixing block 4. The outer wall of the locking block 5 is slidably connected to the front inner wall of the slider 19. The outer wall of the locking block 5 is locked onto the inner wall of the fixing block 4. The locking of the locking block 5 and the fixing block 4 fixes the slider 19. One end of the spring 18 is fixedly connected to the rear side of the locking block 5, and the other end of the spring 18 is fixedly connected to the front inner wall of the slider 19.

[0035] Reference Figure 5 The limiting component includes a rotating column 12, which is threadedly connected to the lower inner wall of the cylinder 1. The rotating column 12 can move up and down by rotating. A fixing ring 17 is fixedly connected to the outer wall of the rotating column 12. The fixing ring 17 moves downward by rotating the rotating column 12, so that the lower side of the fixing ring 17 abuts against the inner wall of the rotating shaft 10 to fix the position of the rotating shaft 10. Rotating the rotating column 12 in the opposite direction causes the fixing ring 17 to move upward, so that the lower side of the fixing ring 17 leaves the contact with the inner wall of the rotating shaft 10, and the rotating shaft 10 can then rotate. The outer wall of the locking block 5 is slidably connected to the front inner wall of the slider 19, and the outer wall of the locking block 5 is locked onto the inner wall of the fixing block 4.

[0036] Working principle: When storing engineering drawings, first rotate and open the cylinder cover 6, roll the drawing into a cylindrical shape and place it into the cylinder 1. Then rotate the shaft 10, which drives the rotating disk 8 to rotate synchronously. The arc groove 16 on the rotating disk 8 rotates with it. Since the upper side of the moving block 15 is slidably connected in the arc groove 16, the movement of the arc groove 16 will force the four moving blocks 15, which are evenly distributed in a ring, to slide along the inner wall of the fixed disk 7 away from the shaft 10. When the moving block 15 moves, the abutment 9 fixedly connected to it moves synchronously. The abutment 9 slides in the rotating disk 13 through the connecting block 14 to maintain stability. Finally, the abutment 9 drives the buffer pad at the end to press against the drawing, fixing the drawing in the center position of the cylinder 1 from four directions, preventing the drawing from shaking and causing wrinkles.

[0037] After securing the drawing, rotate the rotating column 12, causing it to move the fixing ring 17 downwards. The lower side of the fixing ring 17 abuts against the inner wall of the rotating shaft 10, thereby fixing the position of the rotating shaft 10 and preventing it from rotating on its own when not in operation, which could cause the drawing to become loose. Then, cover the cylinder with the cover 6. The sealing ring 11 on the inner wall of the cylinder 1 cooperates with the cover 6 to enhance the sealing and achieve a moisture-proof effect.

[0038] When the storage tube needs to be retrieved, it can be carried directly by the carrying strap 3 on the fixing block 2. If it is not necessary to carry it by hand, press the locking block 5 to compress the spring 18 and retract it into the slider 19, thereby releasing the locking block 5 from the fixing block 4. Move the slider 19 upward to straighten the carrying strap 3, and then release the locking block 5. The spring 18 will reset and push the locking block 5 to re-engage the fixing block 4, making the carrying strap 3 more aesthetically pleasing.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
