Description

TECHNICAL FIELD

[0001] The utility model relates to drawing storage equipment technical field, especially, a kind of design drawing storage box. BACKGROUND

[0002] In design, drawing and engineering fields, drawing is indispensable work tool. Traditional drawing storage mode often uses folder or drawer and other simple devices, these methods not only occupy large space when storing a large number of drawings, but also are inconvenient to carry and find.

[0003] For example, Chinese utility model patent (CN222572908U) discloses a design drawing storage box, which is characterized in that: the rectangular frame opening is used to place the drawing flat, and the folding saves space and facilitates carrying. The rectangular hole two reduces the folding angle to prevent accidental opening. The partition plate can be adjusted to adapt to the width of the drawing, and the strip-shaped hole facilitates observation.

[0004] In summary, the existing technology uses the sliding opening of the closed cover to expose the opening on the rectangular frame two to store and take the design drawing. However, this method has the following technical problems: the opening on the side of the rectangular frame two is relatively small, and the drawing is pushed into the rectangular frame two for storage through the relatively small side opening. Since the drawing is generally soft, the drawing may be bent during storage. In addition, since the opening is relatively small, it is also inconvenient for the operator to arrange and find the drawing when there are many drawings. Therefore, the present application provides a design drawing storage box to solve the technical problems mentioned in the above patent and provides a new technical solution. UTILITY MODEL CONTENT

[0005] Based on this, it is necessary to provide a design drawing storage box to address the aforementioned technical problems. By unfolding the two boxes and then pulling the lids one by one, the lids can rotate relative to the boxes, thereby opening the top opening of the box. The operator can then use the top opening to store, organize, or retrieve drawings, improving the practicality of the device. After placing the drawings in the box, simply close the two lids onto the corresponding boxes, then push the sliding plate to make room for the second U-shaped handle. Then rotate the box to fold the two boxes in half, aligning the insert with the slot on the second U-shaped handle. Releasing the sliding plate allows the insert to be inserted into the second U-shaped handle. By restricting the relative movement of the two lids, the rotation between the two boxes can be restricted. This process is simple to operate, improving the convenience for the operator.

[0030] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0031] As described in the background art, the openings on the two sides of the rectangular frame of the above-mentioned device are relatively small. The drawings are pushed into the rectangular frame for storage by relying on the relatively small side openings. Since the drawings are generally soft, they may be bent during the storage process. Furthermore, due to the relatively small openings, it is not convenient for the operator to organize and search for drawings when there are many drawings stored.

[0032] To solve this technical problem, this utility model provides a design drawing storage box, which is used for storing design drawings.

[0033] For details, please refer to Figures 1-5 The design drawing storage box specifically includes:

[0034] Two boxes 1 are rotatably connected to each other. The inner walls of the two boxes 1 are rotatably connected to the covers 2 respectively. The inner walls of the two covers 2 are fixedly connected to the first magnet 3 respectively. The inner walls of the two boxes 1 are fixedly connected to the second magnet 4 respectively. The covers 2 are provided with a first limiting mechanism 5. The boxes 1 are provided with a second limiting mechanism 6. The two covers 2 are provided with multiple pressing mechanisms 7 respectively.

[0035] The first limiting mechanism 5 includes a first U-shaped handle 8, a second U-shaped handle 9, a moving component, and a plugging component. The first U-shaped handle 8 is fixedly connected to the outer wall of one of the covers 2, and the second U-shaped handle 9 is fixedly connected to the outer wall of the other cover 2.

[0036] The second limiting mechanism 6 includes a housing 14, a hollow shell 15, a pressing component, and a rotating component. The outer wall of one of the housings 1 is fixedly connected to the housing 14, and the outer wall of the other housing 1 is fixedly connected to the hollow shell 15.

[0037] The extrusion mechanism 7 includes a threaded post 25, a limiting rod 24, and an extrusion assembly. The inner wall of the cover 2 is rotatably connected to the threaded post 25, and the outer wall of the cover 2 is fixedly connected to the limiting rod 24.

[0038] The design drawing storage box provided by this utility model allows for the storage, organization, and retrieval of drawings by unfolding the two box bodies 1 and then pulling the lids 2 one by one, causing the lids 2 to rotate relative to the box bodies 1. This opens the top opening of the box body 1, allowing the operator to store, organize, and retrieve drawings through the top opening, thus improving the practicality of the device. After placing the drawings inside the box body 1, simply close the two lids 2 onto the corresponding box body 1, then push the sliding plate 11 to create space for the insertion rod 13 to accommodate the second U-shaped handle 9. Then, rotate the box body 1 to fold and rotate the two box bodies 1 together. At this point, the insertion rod... Align the rod 13 with the slot on the second U-shaped handle 9, and then release the sliding plate 11. This allows the rod 13 to be inserted into the second U-shaped handle 9. By restricting the relative movement of the two covers 2, the rotation between the two boxes 1 can be restricted. This process is simple to operate and improves the convenience of use for the operator. Furthermore, when the operator moves the device, the operator can put their hand into the first U-shaped handle 8 and the second U-shaped handle 9 and hook their fingers onto the sliding plate 11. Under the action of the device's gravity, the rod 13 is stably inserted into the second U-shaped handle 9, which improves the stability of the device.

[0039] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0040] Example 1:

[0041] Please refer to Figures 1-5 A design drawing storage box, comprising:

[0042] Two boxes 1 are rotatably connected to each other. The inner walls of the two boxes 1 are rotatably connected to lids 2. The inner walls of the two lids 2 are fixedly connected to first magnets 3 and second magnets 4. The lids 2 are provided with first limiting mechanisms 5 and the boxes 1 are provided with second limiting mechanisms 6. The two lids 2 are provided with multiple pressing mechanisms 7. When the lids 2 are closed on the boxes 1, the corresponding first magnets 3 and second magnets 4 attract each other, reducing the possibility of the lids 2 accidentally opening when the two boxes 1 are rotated open.

[0043] The first limiting mechanism 5 includes a first U-shaped handle 8, a second U-shaped handle 9, a moving component, and a plugging component. The first U-shaped handle 8 is fixedly connected to the outer wall of one of the covers 2, and the second U-shaped handle 9 is fixedly connected to the outer wall of the other cover 2. The first limiting mechanism 5 can initially limit the rotation between the two boxes 1 after folding.

[0044] The second limiting mechanism 6 includes a housing 14, a hollow shell 15, a pressing component, and a rotating component. The outer wall of one of the boxes 1 is fixedly connected to the housing 14, and the outer wall of the other box 1 is fixedly connected to the hollow shell 15. The second limiting mechanism 6 further restricts the rotation between the two boxes 1 after folding.

[0045] The extrusion mechanism 7 includes a threaded post 25, a limiting rod 24, and an extrusion assembly. The inner wall of the cover 2 is rotatably connected to the threaded post 25, and the outer wall of the cover 2 is fixedly connected to the limiting rod 24, which extrudes and limits the drawings placed inside the box 1.

[0046] The moving component includes fixed rods 10. Two fixed rods 10 are fixedly connected to the inner wall of the first U-shaped handle 8. A sliding plate 11 is slidably connected to the inner wall of the first U-shaped handle 8. The sliding plate 11 is slidably connected to the outer wall of the two fixed rods 10. Springs 12 are respectively sleeved on the outside of the two fixed rods 10. The two ends of the springs 12 are respectively fixedly connected to the outer wall of the sliding plate 11 and the inner wall of the first U-shaped handle 8. The moving component makes the sliding plate 11 tend to move away from the corresponding cover 2.

[0047] The plug-in assembly includes plug rods 13. Multiple plug rods 13 are fixedly connected to the outer wall of the sliding plate 11. The multiple plug rods 13 are movably plugged into the second U-shaped handle 9. The plug rods 13 are plugged into the second U-shaped handle 9 to restrict the separation between the two covers 2, thereby restricting the mutual rotation and opening of the two boxes 1.

[0048] Through the above structural design, when searching for drawings, by unfolding the two boxes 1 and then pulling the covers 2 one by one, the covers 2 can rotate relative to the boxes 1, causing the first magnet 3 and the second magnet 4 to separate, opening the top opening of the boxes 1. The operator can then store, organize, and search for the drawings inside the boxes 1 with the top opening. After placing the drawings in the boxes 1, simply close the two covers 2 onto the corresponding boxes 1, causing the first magnet 3 to be attracted to the corresponding second magnet 4. Then push the sliding plate 11, causing it to slide outside the fixed rod 10, causing the two springs 12 to deform, leaving space for the insertion rod 13 to make room for the second U-shaped handle 9. Then rotate the boxes 1, folding and rotating the two boxes 1 in half. At this time, the insertion rod 13 is aligned with the slot on the second U-shaped handle 9. Then release the sliding plate 11, and the insertion rod 13 can be inserted into the second U-shaped handle 9 under the action of the spring force of the spring 12. Thus, by restricting the relative movement of the two covers 2, the rotation between the two boxes 1 can be restricted.

[0049] Example 2:

[0050] The design drawing storage box provided in Example 1 is further optimized, specifically, as follows: Figure 4 As shown, the pressing assembly includes a ratchet plate 16, which is slidably connected to the inner wall of the housing 14. The ratchet plate 16 is movably inserted into the hollow shell 15. A sliding baffle 17 is fixedly connected to the top of the ratchet plate 16. The sliding baffle 17 is slidably connected to the inner wall of the housing 14. The sliding baffle 17 facilitates the operator to push and pull the ratchet plate 16 to slide inside the housing 14.

[0051] The rotating assembly includes a rotating shaft 18, which is rotatably connected to the inner wall of the housing 14. A pawl 19 adapted to the ratchet plate 16 is fixedly connected to the outer wall of the rotating shaft 18. Torsion springs 20 are respectively sleeved on the outside of the rotating shaft 18 and on both sides of the pawl 19. The two ends of the torsion springs 20 are respectively fixedly connected to the outer wall of the pawl 19 and the inner wall of the housing 14. The rotating assembly can restrict the movement of the ratchet plate 16, so that the operator can directly push the housing 14 to insert the ratchet plate 16 into the hollow housing 15, but cannot directly pull the sliding baffle 17 to make the ratchet plate 16 leave the hollow housing 15.

[0052] With the above structural design, when restricting the rotation between the two folded boxes 1, the operator presses down on the sliding baffle 17, causing both the sliding baffle 17 and the ratchet plate 16 to slide inside the housing 14. This allows the ratchet plate 16 to insert into the hollow shell 15, thereby restricting the relative rotation between the two boxes 1. When it is necessary to release the relative rotation between the two folded boxes 1, the rotating shaft 18 is rotated, causing the pawl 19 to leave the ratchet plate 16. During this process, the torsion spring 20 deforms, thereby releasing the restriction on the ratchet plate 16 sliding in the direction away from the hollow shell 15 within the housing 14. Then, by pulling the sliding baffle 17, the ratchet plate 16 can be removed from the hollow shell 15, and the two boxes 1 can be rotated and unfolded through the first limiting mechanism 5.

[0053] Example 3:

[0054] The design drawing storage box provided in Example 1 is further optimized, specifically, as follows: Figure 2 and Figure 5 As shown, the extrusion assembly includes an internally threaded plate 21 and an extrusion plate 23. The outer wall of the threaded column 25 is threadedly connected to the internally threaded plate 21. The internally threaded plate 21 is slidably connected to the outer wall of the limiting rod 24. Multiple connecting rods 22 are fixedly connected to the outer wall of the internally threaded plate 21. All multiple connecting rods 22 are fixedly connected to the outer wall of the extrusion plate 23. When the extrusion plate 23 extrudes the drawing, it will not cause the corresponding first magnet 3 and second magnet 4 to separate, so as to reduce the situation that the two boxes 1 are not folded tightly in the future.

[0055] With the above structural design, after the drawings are stored in the box 1, the cover 2 is closed on the box 1, so that the corresponding first magnet 3 and second magnet 4 are attracted. Then, the operator can use the pressing mechanism 7 to restrict the drawings in the box 1 one by one. By rotating the threaded column 25, the internal threaded plate 21 can be driven to rise or fall under the restriction of the limiting rod 24. Then, the pressing plate 23 can be raised or lowered through the connecting rod 22. Then, the pressing plate 23 can be lowered by rotating the threaded column 25 to press the drawings. When it is necessary to take out the drawings, the threaded column 25 needs to be rotated in the opposite direction to make the pressing plate 23 leave the drawings to a suitable position. Then, the cover 2 is rotated to expose the opening of the box 1 and then the drawings can be taken out.
