Description

Technical Field

[0001] This utility model relates to the field of architectural drawing clamping technology, and more specifically, it relates to an architectural drawing display clamping device. Background Technology

[0002] Construction cost engineers are engineering economic professionals responsible for and assisting in the pricing, valuation, and management of construction project costs to protect their legitimate rights and interests. When calculating construction costs, they typically use various architectural drawings, which are usually displayed using drawing clamping devices. Existing drawing clamping devices can only hold drawings of the same fixed size. When cost engineers need to display drawings of different sizes simultaneously (such as an A0-size site plan and an A3-size detail drawing), they have to frequently change the clamping devices, reducing the flexibility and practicality of the entire system and making it very inconvenient to use. Secondly, existing drawing clamping devices cannot expand the display area. When comparing two drawings, two separate clamping devices are required, increasing costs. Utility Model Content

[0028] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0029] Please see Figures 1-6A building drawing display clamping device includes two display panels 1, each display panel 1 is fixedly equipped with a clamp 2, the display panel 1 is provided with two sliding grooves 3, each sliding groove 3 is provided with a slider 4, one end of each slider 4 passes through the sliding groove 3 and is fixedly connected to a connecting rod 5, a rotating rod 6 is rotatably provided between the two sliders 4, a push frame 7 is fixedly provided on the rotating rod 6, a torsion spring 8 is movably sleeved on the outside of the rotating rod 6, the two ends of the torsion spring 8 abut against the push frame 7 and the connecting rod 5 respectively, a connecting plate 9 is fixedly provided on the push frame 7, a pressing plate 10 is fixedly provided at one end of the connecting plate 9, two support plates 11 are fixedly provided on the connecting plate 9, a pressing roller 12 is rotatably provided between the two support plates 11, a rotating arm 22 is fixedly connected to both ends of the rotating rod 6 passing through the sliders 4 respectively, a locking block 23 is fixedly provided at one end of the rotating arm 22, and multiple locking slots 24 that cooperate with the locking blocks 23 are provided on the display panel 1.

[0030] In this embodiment, when the cost estimator needs to clamp and fix the architectural drawings onto the display board 1 during the construction cost estimation process, they push the push frame 7 by hand. The push frame 7 drives the rotating rod 6 to rotate, and the torsion spring 8 deforms, causing the connecting plate 9 to separate the pressing plate 10 from the display board 1, while keeping the pressing roller 12 also separated from the display board 1. At the same time, the rotating rod 6 drives the rotating arm 22 and the locking block 23 to rotate, causing the locking block 23 to separate from the locking slot 24. One end of the architectural drawing is passed between the pressing plate 10 and the display board 1, so that one end of the architectural drawing moves to the clamp 2. The push frame 7 is then released, and under the action of the torsion spring 8, the push frame 7, connecting plate 9, pressing plate 10, support plate 11, pressing roller 12, rotating arm 22, and locking block 23 move. Returning to its original position, the pressing plate 10 fixes the architectural drawing, and the locking block 23 is inserted into the slot 24 to fix the slider 4. The clamp 2 is opened to clamp and fix one end of the architectural drawing. The pusher 7 is pushed to separate the pressing plate 10 from the drawing and drive the pressing roller 12 to contact the drawing. The pusher 7 is pushed, and the pusher 7 drives the two sliders 4 to move along the sliding groove 3 through the rotating rod 6. The pressing roller 12 rotates to flatten the drawing. When the pressing roller 12 moves to the other end of the drawing, the pusher 7 is released, so that the pressing plate 10 cooperates with the display plate 1 to clamp and fix the other end of the drawing. At this time, the locking block 23 is inserted into the corresponding slot 24 to fix the slider 4, thus completing the clamping and fixing of the architectural drawing.

[0031] Please see Figures 1-6As an implementation method to expand the display area: a support base 13 is fixedly provided on one of the display panels 1, and a rotating shaft 14 is fixedly provided at both ends of the support base 13. A rotating seat 15 is rotatably connected to the rotating shaft 14. The rotating seat 15 is fixedly connected to the other display panel 1. A toothed ring 16 is fixedly provided at one end of each rotating shaft 14 through the rotating seat 15. A limiting shell 17 is fixedly provided on the rotating seat 15. A screw 18 is rotatably provided inside the limiting shell 17. A handle 19 is fixedly provided at one end of the screw 18 through the limiting shell 17. A fixing plate 20 is threadedly connected to the screw 18. A fixing groove 21 that mates with the toothed ring 16 is provided on the fixing plate 20.

[0032] More specifically, during the construction cost process, when it is necessary to compare and display two drawings, the two handles 19 are rotated in sequence. The handles 19 drive the screw 18 to rotate. Since the screw 18 is threadedly connected to the fixing plate 20, the fixing plate 20 moves along the limiting shell 17. The fixing groove 21 on the fixing plate 20 separates from the toothed ring 16. At this time, one of the display plates 1 is rotated, causing the display plate 1 to drive the two rotating seats 15 to rotate around the rotating shaft 14. When the display plate 1 rotates out and aligns with the other display plate 1, the opposite operation is used to move the fixing plate 20 to the outside of the toothed ring 16 and fix the toothed ring 16 through the fixing groove 21. This fixes the rotated display plate 1, increases the display area, and can clamp and fix the two architectural drawings.

[0033] In summary, during the use or operation of the overall equipment: When the cost estimator needs to clamp and fix the architectural drawings onto the display board 1 during the construction cost estimation process, the pusher 7 is pushed by hand. The pusher 7 drives the rotating rod 6 to rotate, and the torsion spring 8 deforms, causing the connecting plate 9 to separate the pressing plate 10 from the display board 1, while keeping the pressing roller 12 also separated from the display board 1. At the same time, the rotating rod 6 drives the rotating arm 22 and the locking block 23 to rotate, causing the locking block 23 to separate from the locking slot 24. One end of the architectural drawing is passed between the pressing plate 10 and the display board 1, so that one end of the architectural drawing moves to the clamp 2. The pusher 7 is then released. Under the action of the torsion spring 8, the pusher 7, connecting plate 9, pressing plate 10, support plate 11, pressing roller 12, rotating arm 22, and locking block are all released. Move 23 back to its original position. At this time, the pressing plate 10 fixes the architectural drawing, and the locking block 23 is inserted into the slot 24 to fix the slider 4. Open the clamp 2 to clamp and fix one end of the architectural drawing. Continue to push the push frame 7 so that the pressing plate 10 separates from the drawing and drives the pressing roller 12 to contact the drawing. Push the push frame 7, and the push frame 7 drives the two sliders 4 to move along the sliding groove 3 through the rotating rod 6. The pressing roller 12 rotates to flatten the drawing. When the pressing roller 12 moves to the other end of the drawing, release the push frame 7 so that the pressing plate 10 cooperates with the display plate 1 to clamp and fix the other end of the drawing. At this time, the locking block 23 is inserted into the corresponding slot 24 to fix the slider 4, thus completing the clamping and fixing of the architectural drawing.

[0034] During the construction cost estimation process, when it is necessary to compare and display two drawings, the two handles 19 are rotated in sequence. The handles 19 drive the screw 18 to rotate. Since the screw 18 is threadedly connected to the fixing plate 20, the fixing plate 20 moves along the limiting shell 17. The fixing groove 21 on the fixing plate 20 separates from the toothed ring 16. At this time, one of the display plates 1 is rotated, causing the display plate 1 to drive the two rotating seats 15 to rotate around the rotating shaft 14. When the display plate 1 rotates out and aligns with the other display plate 1, the opposite operation is used to move the fixing plate 20 to the outside of the toothed ring 16 and fix the toothed ring 16 through the fixing groove 21. This fixes the rotated display plate 1, increases the display area, and can clamp and fix the two architectural drawings. When it is not necessary to compare the two architectural drawings, the opposite operation can be used to store them. The lower ends of the two display plates 1 are respectively provided with two support legs to support the entire device. The support legs on the two display plates are staggered, so that the support legs will not interfere when storing one of the display plates 1.

[0035] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model 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 this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
