Description

Technical Field

[0001] This utility model relates to the field of drawing storage technology, specifically a design drawing storage device. Background Technology

[0002] Design drawing storage devices are common tools used to store and carry rolled engineering drawings, posters, and other paper documents such as paintings and calligraphy. To accommodate drawings of different sizes, existing technologies typically employ a telescopic sleeve structure to adjust the storage length.

[0003] However, existing design drawing storage devices typically have a single internal cavity. In actual use, when multiple rolls of drawings are placed in the same container, the drawings naturally spread out and press against each other due to their own paper tension. If one of the drawings needs to be removed, the friction between the papers can easily cause the other drawings to slide out as well, or even damage the edges of the drawings. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model proposes a design drawing storage device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a design drawing storage device, comprising: Outer cylinder, with an opening at its upper end; The inner cylinder has its upper and lower ends connected, and its lower end is inserted into the outer cylinder.

The outer circumferential contour of the insertion protrusion ring is adapted to the outer circumferential contour of the upper end of the inner cylinder. The upper and lower ends of the partition assembly are respectively connected to the lower end of the upper support ring and the upper end of the lower support ring.

[0007] Preferably, the partition assembly includes a central pivot arranged along the axial direction of the inner cylinder, and at least two radial partition plates extending along the axial direction of the inner cylinder; Each of the radial partition plates is rotatably connected to the central rotating shaft. Each radial partition plate is provided with at least one rotating bushing along the axial direction on the side near the central rotating shaft. The rotating bushing is rotatably sleeved on the central rotating shaft. The rotating bushings on different radial partition plates are offset along the axial direction of the central rotating shaft, and the upper and lower ends of the central rotating shaft are respectively provided with shaft end limiting members to restrict the axial disengagement of the rotating bushings.

[0008] Preferably, the upper surface of the lower support ring and the lower surface of the upper support ring are respectively provided with annular guide grooves coaxial with the central rotating shaft; Each of the radial partition plates has guide sliders at its upper and lower ends on the side away from the central axis, and the upper and lower guide sliders are respectively slidably disposed in the corresponding annular guide grooves.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Please see Figures 1 to 8 This utility model provides a design drawing storage device, which mainly includes an outer cylinder 1, an inner cylinder 2, a cylinder cover assembly 3, and a partition assembly. The upper end of the outer cylinder 1 is an open structure, forming an internal accommodating cavity.

[0017] The inner cylinder 2 is a cylindrical structure with both ends open. The lower end of the inner cylinder 2 is inserted into the outer cylinder 1, forming a sleeve-like telescopic structure with the outer cylinder 1. To achieve length adjustment and positioning between the inner cylinder 2 and the outer cylinder 1, multiple positioning recesses 7 are provided at intervals along the axial direction on the outer side wall of the inner cylinder 2. An elastic positioning protrusion 11 is provided on the inner side wall or at the upper end of the outer cylinder 1, which engages with the positioning recesses 7. Specifically, the elastic positioning protrusion 11 is a positioning protrusion that protrudes towards the inside of the outer cylinder 1. When the inner cylinder 2 is pulled out, the positioning protrusion is squeezed and deformed, sliding out of the current positioning recess 7. When adjusted to a suitable length, the positioning protrusion, by its own elasticity, engages with the corresponding positioning recess 7, thereby achieving the positioning of the relative positions of the inner and outer cylinders.

[0018] To divide the single cavity inside the cylinder into multiple independent storage spaces, a partition assembly is provided inside the inner cylinder 2. The partition assembly includes an upper support ring 5, a lower support ring 4, and a partition assembly 6 located between the two. The upper end of the lower support ring 4 is detachably and tightly inserted into the lower end of the inner cylinder 2, and its outer side is provided with a limiting flange that abuts against the lower end face of the inner cylinder 2 to prevent the lower support ring 4 from going too deep into the inner cylinder 2, facilitating subsequent disassembly.

[0019] The upper support ring 5 is detachably fitted onto the upper end of the inner cylinder 2, and a connecting protrusion ring 51 is fixedly connected to its upper surface. The outer circumferential contour of the connecting protrusion ring 51 is adapted to the outer circumferential contour of the upper end of the inner cylinder 2. The upper and lower support rings are detachably connected to the upper and lower ends of the inner cylinder 2, which allows the entire partition assembly to be completely removed when loading an extra-large scroll or when cleaning dust inside the cylinder, thus avoiding the partition assembly occupying space inside.

[0020] Furthermore, the partition assembly 6 is the core structure for achieving adjustable compartmentation. It includes a central rotating shaft 61 arranged axially along the inner cylinder 2, and at least two radial partition plates 62 extending axially along the inner cylinder 2. The upper and lower ends of the partition assembly 6 are respectively connected to the lower end of the upper support ring 5 and the upper end of the lower support ring 4. Each radial partition plate 62 is rotatably connected to the central rotating shaft 61, and at least one rotating bushing 63 is axially spaced on the side of each radial partition plate 62 closest to the central rotating shaft 61. Preferably, each radial partition plate 62 is provided with two rotating bushings 63, and the distance between the two rotating bushings 63 is not less than two-thirds of the length of the radial partition plate 62, so as to ensure smoother and more stable movement when the radial partition plate 62 is moved. The radial partition plate 62 has a protruding retaining strip, which is interference-fitted with the retaining hole on the rotating bushing 63. In order to avoid interference between components, the rotating bushings 63 on different radial partition plates 62 are staggered along the axial direction of the central rotating shaft 61 and are rotated and sleeved on the central rotating shaft 61 in sequence. The upper and lower ends of the central rotating shaft 61 are respectively provided with shaft end limiting members 64 to prevent the rotating bushings 63 from axially disengaging.

[0021] To ensure the smoothness and stability of the radial partition plates 62 during unfolding and rotation adjustment, annular guide grooves 65, coaxial with the central rotating shaft 61, are respectively formed on the upper surface of the lower support ring 4 and the lower surface of the upper support ring 5. Guide sliders 66 are integrally formed at the upper and lower ends of the radial partition plates 62 on the side away from the central rotating shaft 61, and the upper and lower guide sliders 66 are slidably embedded in the corresponding annular guide grooves 65. Users can manually rotate the radial partition plates 62 around the central rotating shaft 61, thereby changing the included angle and volume of each sector compartment according to the diameter of the rolled drawing.

[0022] The cylinder cover assembly 3 is detachably fitted onto the upper end of the inner cylinder 2, specifically mounted on the insertion protrusion ring 51. The cylinder cover assembly 3 includes a cover base 31 and a flip cover 32. One side of the flip cover 32 is hinged to the cover base 31 via a pivot, and the other side is provided with a resilient hook 33; The cover 31 has a corresponding locking block 34 that engages with the elastic hook 33. In use, the flip cover 32 can be opened by simply prying open the elastic hook 33 with one hand, and the flip cover 32 can be locked by pressing it when closing. The operation is convenient. It should be noted that the locking block 34 is provided with an guide angle to facilitate the engagement of the elastic hook 33, and the bottom mating surface of the locking block 34 and the elastic hook 33 is flat.

[0023] Furthermore, considering the convenience of outdoor carrying, a shoulder strap 8 is fixed to the bottom or side wall of the outer tube 1, and a shoulder strap connecting ring 10 is fixedly connected to the outer side of the cover 31. The shoulder strap 8 has a fixed end that is fixedly connected to the outer tube 1 and an adjusting end that passes through a self-locking adjusting buckle 9. The adjusting end wraps around the shoulder strap connecting ring 10, folds back, and re-enters the self-locking adjusting buckle 9 to lock it in place. The self-locking adjusting buckle 9 is preferably a zip-lock buckle. Users can easily adjust the length of the shoulder strap 8 by moving the zip-lock buckle to accommodate different carrying methods such as carrying on one shoulder or crossbody.

[0024] The detailed workflow is as follows: In the initial state, first, according to the length of the drawing, hold the outer cylinder 1 with one hand and pull the inner cylinder 2 upward with the other hand. The elastic positioning inner protrusion 11 on the outer cylinder 1 will slide between the various positioning recesses 7 of the inner cylinder 2 until the storage cylinder is stretched to the required appropriate length. The elastic positioning inner protrusion 11 will then engage with the corresponding positioning recess 7 to complete the positioning.

[0025] When loading the drawings, use one hand to pry open the elastic hook 33 on the side of the flip cover 32, causing the elastic hook 33 to disengage from the locking block 34 on the cover seat 31, and then lift the flip cover 32 upwards to expose the internal compartments. Based on the thickness differences of the various rolls of drawings, the operator reaches in and manipulates the radial partition plate 62. The guide slider 66 slides smoothly within the annular guide grooves 65 at both ends, and the rotating bushing 63 of the radial partition plate 62 rotates around the central axis 61, thereby dividing the internal space into several independent fan-shaped compartments of varying sizes.

[0026] Then, insert the different engineering drawings or posters into their respective compartments. The drawings will slightly spring open due to their own tension within the compartment, but thanks to the physical obstruction of the radial partition 62, they are confined to their own compartments and will not become entangled with other drawings. After loading, close the flip-top cover 32. The user can then adjust the length of the shoulder strap 8 using the self-locking adjustment buckle 9 for travel.

[0027] When a specific drawing needs to be retrieved upon arrival at the destination, simply open the flip cover 32 and pinch the edge of the desired drawing upwards to pull it out. Due to the isolation effect of the bulkhead, the extraction process is extremely smooth. Drawings in other compartments are not affected by the pulling friction and remain in their original positions, achieving accurate and damage-free retrieval of the drawings.

[0028] When loading an extra-large scroll, simply remove the cap assembly 3 and disassemble the divider assembly to restore the interior to a single, wide cavity. Then, pull out and position the inner cylinder 2 according to the scroll's length. Finally, place the scroll inside, and directly place the cap assembly 3 onto the top of the inner cylinder 2 and tighten it to complete the loading process.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended technical solutions and their equivalents.
