[0002] Engineering drawing display and storage scrolls are practical tools in the fields of project management and cost estimation. Specifically designed for engineering drawings, they are made of high-quality, durable materials, possessing excellent pressure resistance and moisture resistance, effectively protecting the drawings from damage. The scroll design facilitates the unfolding and rewinding of drawings, allowing for quick display of drawing content in construction sites, meetings, and other scenarios, improving communication efficiency. For cost estimators, it provides organized storage of drawing materials from different stages, facilitating easy access and comparison, and accurate calculation of quantities and costs. In the process of project management, it helps achieve efficient management and utilization of drawings, ensuring the smooth progress of projects.
[0003] However, existing methods for storing engineering drawings have many drawbacks. On the one hand, the clamping and winding operations are performed in separate steps, which is cumbersome and requires additional positioning structures, resulting in a complex overall structure. This not only increases manufacturing costs but also reduces storage efficiency, and the coordination of multiple structures is prone to failure, affecting stability. On the other hand, after winding, there is a lack of effective edge-pressing and positioning methods, making the edges of the drawings prone to loosening. During subsequent handling and storage, they may be shaken or bumped apart, causing damage or loss of the drawings, which brings great inconvenience to engineering data management and fails to meet the needs of efficient, stable, and safe engineering management.

[0020] 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.
[0021] Please see Figures 1-5 As shown, an engineering drawing display and storage reel includes an annular connecting sleeve 1, an elastic snap-fit assembly 5, a first semi-circular take-up roller 6, a second semi-circular take-up roller 7, a press-type friction positioning assembly 8, and a screw-type edge-pressing assembly 9. A linkage disc 2 is rotatably mounted on the inner wall of the annular connecting sleeve 1, and a rotating take-up disc 3 is rotatably inserted into the linkage disc 2. A screw handle 4 is fixedly mounted on one end of the rotating take-up disc 3. The elastic snap-fit assembly 5 is installed in a limit groove on the rotating take-up disc 3, and one end of the elastic snap-fit assembly 5 is slidably inserted into an arc-shaped groove on the linkage disc 2. The first semi-circular take-up roller 6 and the second semi-circular take-up roller 7 are mounted on the elastic snap-fit assembly 5, and the first and second semi-circular take-up rollers 6 and 7 are symmetrically distributed. The press-type friction positioning assembly 8 is installed in an installation groove on the annular connecting sleeve 1 for positioning the linkage disc 2. When the engineering drawings need to be stored, the reel is... One end of the engineering drawing is placed between the first semicircular take-up roller 6 and the second semicircular take-up roller 7. The pressing friction positioning component 8 is controlled to position the linkage disk 2 relative to the annular connecting sleeve 1. The handle 4 is controlled to rotate the rotating take-up disk 3 on the linkage disk 2, causing one end of the elastic locking component 5 to slide in the arc-shaped groove. When one end of the elastic locking component 5 moves to the contraction end of the arc-shaped groove, the elastic locking component 5 drives the first semicircular take-up roller 6 and the second semicircular take-up roller 7 to move closer, thereby clamping one end of the engineering drawing. The pressing friction positioning component 8 is then released, and the rotating take-up disk 3 is continuously controlled to rotate. By rotating the elastic locking component 5 and the linkage disk 2 synchronously, clamping and winding can be integrated without the need for additional positioning structures. This achieves integrated clamping and winding of the drawing, reduces processes and structures, facilitates project management, reduces costs, and improves storage efficiency and stability. The screw-type edge-pressing assembly 9 is installed in the annular groove on the inner wall of the annular connecting sleeve 1. It is used to press and position the drawing after it is wound up. After winding, the screw-type edge-pressing assembly 9 is controlled to move in a circular motion in the arc-shaped groove, correspond to one side of the engineering drawing and press it up, so as to achieve positioning after winding and ensure the stability of storage.
[0022] As a technical optimization of this utility model, the elastic snap-fit assembly 5 includes a limiting slide rod 501 fixed in the limiting slide groove. A pressing slider 502 is slidably sleeved on the limiting slide rod 501. The first semi-circular take-up roller 6 and the second semi-circular take-up roller 7 are respectively fixed on the pressing sliders 502 on both sides through an L-shaped connecting rod 503. The pressing slider 502 is elastically connected to the inner wall of one end of the limiting slide groove through a connecting spring 504. An extension connecting rod 505 is fixedly installed on the pressing slider 502. A connecting ball 506 is rotatably installed at one end of the extension connecting rod 505. The connecting ball 506 is in close contact with the inner wall of the arc-shaped groove. When storing the drawing, one end of it is first placed between the first semi-circular take-up roller 6 and the second semi-circular take-up roller 7. The pressing friction positioning assembly 8 is controlled to position the linkage disc 2. The rotating handle 4 rotates the take-up disc 3, causing the connecting ball 506 to slide in the arc-shaped groove. When the connecting ball 506 slides to the constricted end of the arc-shaped groove, it pushes the extension connecting rod 505 and the pressing slider 502 to move along the limiting slide bar 501, compressing the connecting spring 504, so that the first semicircular winding roller 6 and the second semicircular winding roller are close to the clamping drawing, and then the positioning component is released to continue winding.
[0023] As a technical optimization of this utility model, the press-type friction positioning component 8 includes a press rod 801 slidably inserted into the mounting groove. A rubber pad 802 is fixedly installed at one end of the press rod 801, and the rubber pad 802 is in close contact with the outer wall of the linkage disc 2. A press head 803 is fixedly installed at the other end of the press rod 801. The press head 803 is elastically connected to the inner wall of the mounting groove via a return spring 804. When positioning the linkage disc 2, the press head 803 is pressed down forcefully, pushing the press rod 801 to slide in the mounting groove, causing the rubber pad 802 to press tightly against the outer wall of the linkage disc 2. Positioning is achieved by limiting its rotation through friction. After positioning is completed, the press head 803 is released. Under the action of the return spring 804, the press rod 801 causes the rubber pad 802 to rebound, disengaging from the linkage disc 2, releasing the positioning, and allowing the linkage disc 2 to rotate freely.
[0024] As a technical optimization of this utility model, the screw-type edge-pressing assembly 9 includes an arc-shaped slider 901 that is slidably engaged in an annular groove. A connecting strip 902 is fixedly installed on the arc-shaped slider 901. A push screw 903 is threadedly inserted into the connecting strip 902. A screw-pressing column 904 is fixedly installed at one end of the push screw 903. A pressing plate 906 is rotatably installed at the other end of the push screw 903 through a rotating joint 905. The pressing plate 906 is slidably connected to the connecting strip 902 through a sliding limit post 907. In use, according to the position of one end of the drawing, the arc-shaped slider 901 is pushed to slide in the annular groove, causing the pressing plate 906 to make a circular motion. After the drawing is rolled up, the screw-pressing column 904 is held and rotated, and the push screw 903 rotates accordingly. Under the action of the thread, the pressing plate 906 is pushed to move along the sliding limit post 907 towards the edge of the drawing until the pressing plate 906 is tightly fitted and pressed against the edge of the drawing, so as to achieve stable positioning of the drawing after winding.
