Description

Technical Field

[0001] This utility model relates to the technical field of drawing and document flattening and pressing devices, and in particular to a drawing and document flattening and pressing device. Background Technology

[0002] In fields such as archives management, engineering design, and library materials, a large number of paper documents such as drawings, files, and blueprints become curled and wrinkled due to long-term storage or frequent handling. In order to facilitate digital scanning, archiving, preservation, or display, these curled drawings need to be flattened and temporarily or permanently compressed.

[0003] Currently, the common method for flattening and securing drawings is to place the drawings on a flat table and then press them down with heavy objects such as multiple thick books, wooden boards, or special weights for an extended period. While simple, this method results in uneven pressure, unsatisfactory flattening, and the removal of the weights is time-consuming, laborious, and inefficient. Furthermore, when applying pressure to the drawings, the pressure points are scattered when only pressing down on the periphery, easily leading to insufficient compaction in the center and bulging. Therefore, a drawing flattening and securing device is needed to solve these problems. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A drawing and document flattening and securing device, comprising,

[0007] A base component, comprising a base plate, the top of which is provided with a pressing surface for flattening the drawing;

[0008] The pressing surface includes a bearing seat fixed to the top edge of the base plate. A rotating shaft is movably connected inside the bearing seat through a through hole. Both rotating shafts are fixed to both ends of the beam shaft. An acrylic pressure plate is connected to the side of the beam shaft. A disc end is provided at the end of the rotating shaft. A torsion spring A abuts between the disc end of the rotating shaft and the side of the bearing seat end. The torsion spring A is sleeved on the surface of the rotating shaft. The acrylic pressure plate has a transparent structure design.

[0009] Preferably, the top left and right sides of the base plate are provided with two positioning side plates to constrain the edge of the drawing. A groove is provided at the center of the bottom end of the base plate. The positioning side plates are provided on the left and right sides of the base plate to constrain the edge of the drawing, prevent it from shifting during the flattening process, and ensure accurate positioning of the drawing.

[0010] Preferably, rubber pillars are embedded in the four corners of the base plate through through holes, and flexible pads are connected to the top of the rubber pillars. The flexible pads are laid on the surface of the base plate and are made of soft materials such as rubber or foam to prevent the drawings from being scratched by hard surfaces when flattened, while also providing cushioning.

[0011] Preferably, the acrylic pressure plate has concave surfaces on both the left and right sides, and a lever B is provided on one side of the bottom end of the acrylic pressure plate. The acrylic pressure plate is made of transparent material, which makes it easy for the operator to observe the position of the drawing and the flattening state. Its concave surface is designed to insert the edge of the drawing, thereby causing the drawing to be over-wound.

[0012] Preferably, a lever plate A is provided at the center of the beam shaft surface, and a through hole for hooking is provided at the center of lever plate A.

[0013] Preferably, a fixing part is provided at the position of the side of the base plate near the concave surface of the acrylic pressure plate. The fixing part includes a hanging plate fixed to the side of the base plate. A shaft cylinder is connected to the surface of the hanging plate, and an inner liner shaft is installed inside the shaft cylinder through a through hole. Movable frames are connected to both ends of the inner liner shaft. A pressure block is movably installed between the two movable frames. A torsion spring B abuts between the end face of the shaft cylinder and the end face of the movable frame. The torsion spring A provides automatic downward pressure. When the acrylic pressure plate is released, the restoring force of the torsion spring A drives the acrylic pressure plate to press down evenly.

[0014] Preferably, the pressure block is designed as an ellipse, and one side of the pressure block is set as a plane flush with the surface of the flexible pad. The pressure block is designed as an ellipse with one side being a plane, and the angle can be adjusted as needed to cooperate with the flexible pad to achieve precise pressing and fixing of the edge of the drawing.

[0015] This utility model has at least the following beneficial effects:

[0016] 1. The pressing section of this device adopts a linkage design between torsion spring A and acrylic pressure plate. When the drawing is placed on the flexible pad, the acrylic pressure plate is released. The restoring force of torsion spring A drives the rotating shaft and beam shaft to rotate, so that the acrylic pressure plate automatically and evenly presses down on the surface of the drawing. Since the acrylic pressure plate is made of transparent material and has a large coverage area, the operator can observe the position of the drawing during the pressing process to ensure that the pressure is evenly distributed, especially for the central area of ​​the drawing, avoiding the problems of pressure dispersion and bulging in the middle when pressing with traditional heavy objects.

[0017] 2. The fixing part of this device is located on the side of the base plate and includes a movable frame, a pressure block and a torsion spring B. After the drawing is initially flattened by the acrylic pressure plate, the operator can move the movable frame to adjust the position of the pressure block. The restoring force of the torsion spring B is used to make the pressure block locally reinforce and solidify the edge of the drawing or specific wrinkled areas. The pressure block is designed to be elliptical and has a flat side. The angle can be adjusted as needed to ensure that it fits the surface of the flexible pad, further enhancing the overall flattening effect of the drawing. It is especially suitable for large-format or easily curled drawing files. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] Reference Figures 1-5 A drawing and document flattening and securing device, comprising:

[0030] The base component 1 includes a base plate 11, and the top of the base plate 11 is provided with a pressing surface 2 for pressing the drawing flat;

[0031] The pressing surface 2 includes a bearing seat 21 fixed to the top edge of the base plate 11. A rotating shaft 26 is movably connected inside the bearing seat 21 through a through hole. Both rotating shafts 26 are fixed to both ends of the beam shaft 22. An acrylic pressure plate 24 is connected to the side of the beam shaft 22. A disc end is provided at the end of the rotating shaft 26. A torsion spring A27 abuts between the disc end of the rotating shaft 26 and the side of the bearing seat 21. The torsion spring A27 is sleeved on the surface of the rotating shaft 26. The acrylic pressure plate 24 has a transparent structure design.

[0032] Two positioning side plates 12 constraining the edge of the drawing are provided on the top left and right sides of the base plate 11, and a groove is provided at the center of the bottom end of the base plate 11.

[0033] Rubber posts 14 are embedded in the four corners of the base plate 11 through through holes, and the top of the rubber posts 14 is connected to a flexible pad 13.

[0034] The acrylic pressure plate 24 has concave surfaces on both sides, and a lever B25 is provided on one side of the bottom end of the acrylic pressure plate 24.

[0035] A lever plate A23 is provided at the center of the surface of beam shaft 22, and a through hole for hooking is provided at the center of lever plate A23.

[0036] A fixing part 3 is provided on the side of the base plate 11 near the concave surface of the acrylic pressure plate 24. The fixing part 3 includes a hanging plate 31 fixed to the side of the base plate 11. A shaft cylinder 32 is connected to the surface of the hanging plate 31. An inner liner shaft 33 is inserted and installed inside the shaft cylinder 32 through a through hole. Movable frames 35 are connected to both ends of the inner liner shaft 33. A pressure block 36 is movably installed between the two movable frames 35. A torsion spring B34 abuts between the end face of the shaft cylinder 32 and the end face of the movable frame 35.

[0037] The pressure block 36 has an overall elliptical design, and one side of the pressure block 36 is set as a plane flush with the surface of the flexible pad 13.

[0038] Positioning side plates 12 are set on the left and right sides of the base plate 11 to constrain the edges of the drawing and prevent it from shifting during the flattening process, ensuring accurate positioning of the drawing. Flexible pads 13 are laid on the surface of the base plate 11. The flexible pads 13 are made of soft materials, such as rubber or foam, to prevent the drawing from being scratched by hard surfaces during flattening, while also providing cushioning and enhancing the flattening effect. Rubber columns 14 are embedded in the four corner through holes of the base plate 11 to play a role in anti-slip and shock absorption, ensuring that the device is stable and does not slide during operation.

[0039] The acrylic pressure plate 24 is made of transparent material, making it easy for the operator to observe the position and flattening status of the drawing. Its concave design allows the drawing to be inserted along the edge, preventing excessive curling. The levers A23 and B25 are used to assist in lifting and adjusting the position of the acrylic pressure plate 24, improving operational efficiency. The torsion spring A27 provides automatic downward pressure. When the acrylic pressure plate 24 is released, the restoring force of the torsion spring A27 drives the acrylic pressure plate 24 to press down evenly, preventing bulging in the middle of the drawing. The torsion spring B34 provides the restoring force of the pressure block 36, ensuring that the pressure block 36 automatically resets after being released, maintaining continuous pressure on the drawing. The pressure block 36 is designed in an elliptical shape with one side being flat. Its angle can be adjusted as needed, and it works with the flexible pad 13 to achieve precise pressure on the edge of the drawing, preventing curling or warping.

[0040] Working principle: When flattening and pressing the drawing, select a drawing of appropriate size and place it on the surface of the flexible pad 13, according to... Figure 2 and Figure 4 As shown, the drawing is embedded in the gap between the positioning side plate 12 and the flexible pad 13 on both sides. When the acrylic pressure plate 24 is lifted, the acrylic pressure plate 24 can drive the beam shaft 22 to drive the rotating shaft 26 to rotate in the shaft seat 21. During the rotation, the beam shaft 22 will twist the torsion spring A27. After the drawing is placed, the torque of the torsion spring A27 can drive the rotating shaft 26 to rotate in the shaft seat 21. The rotating shaft 26, together with the beam shaft 22, drives the acrylic pressure plate 24 to press down on the drawing, so that the center of the drawing can also be pressed, thus preventing the center of the drawing from bulging during the pressing.

[0041] Secondly, according to Figure 2 and Figure 5 As shown, when the drawing is flattened under the pressure of the acrylic pressure plate 24, the movable frame 35 is moved, which drives the inner lining shaft 33 to rotate in the shaft cylinder 32 and twists the torsion spring B34. After smoothing the drawing near the concave surface of the acrylic pressure plate 24 on the surface of the flexible pad 13, the force on the movable frame 35 is released. The torsional elasticity of the torsion spring B34 drives the movable frame 35 to twist and return to its original position, so that the movable frame 35 drives the inner lining shaft 33 to rotate in the shaft cylinder 32. The pressure block 36 is manually rotated and adjusted to a suitable angle so that the plane of the pressure block 36 is opposite to the flexible pad 13. When the movable frame 35 rotates and drives the pressure block 36 to move, the pressure block 36 can press down and fix the drawing on the surface of the flexible pad 13.
