Abstract
Description
Technical Field
[0001] This utility model relates to the field of drawing flattening clips, and in particular to an anti-wrinkle flattening clip for engineering cost drawings. Background Technology
[0002] In the field of construction cost estimation, drawings are core documents, carrying crucial information such as engineering design and construction planning. Their accuracy and completeness directly affect cost estimation and project progress. However, drawings are prone to wrinkles during the drawing, transmission, and storage process. Wrinkled drawings not only affect visual appeal but also obscure key information, increasing the difficulty for cost estimators to interpret the drawings and easily leading to misreading of dimensions and omissions of details, thus affecting the accuracy of cost calculations. Furthermore, uneven drawings can result in unclear scans and image distortion during archiving, hindering digital management and long-term preservation of the drawings.
[0003] In existing technologies, some devices struggle to ensure uniform force on the drawings. When flattening drawings, excessive or insufficient pressure in certain areas often leads to new wrinkles, affecting the integrity and clarity of the drawings and potentially interfering with accurate cost calculations. Secondly, their structural design lacks flexibility, failing to easily adapt to drawings of different sizes, thus limiting their usability and failing to meet the needs of handling various drawing specifications in cost estimation work. Thirdly, most existing flattening clamps lack angle adjustment functionality. When viewing and flattening drawings, users find it difficult to adjust according to their viewing angle and lighting conditions, resulting in poor usability and reduced work efficiency. Utility Model Content

The side of the moving strip closest to the pad is fixedly connected to the pressing plate, and a pull rod is fixedly connected to the side of the moving strip furthest from the pad.
[0008] Furthermore, the pressure plate includes a telescopic spring, which is fixedly connected to the side surface of the moving bar near the pad, and the end of the telescopic spring away from the moving bar is fixedly connected to a smoothing plate.
[0009] Furthermore, the inclined support plate includes a rotating rod, and a connecting groove is provided on the side surface of the pad away from the fixing clamp.

[0025] Please see Figure 1-6 This utility model provides a technical solution: an anti-wrinkle flattening clamp for engineering cost drawings, including a clamping device 1, a flattening mechanism 2, and an inclined support plate 3.
[0026] The following section will explain the specific setup and function of the flattening mechanism 2 and the inclined support plate 3.
[0027] In this embodiment: the clamping device 1 includes a pad 11, and side plates 12 are fixedly connected to both sides of the pad 11. A fixing clamp 13 is fixedly connected to the upper end of one side surface of the pad 11. A sliding groove 14 is provided on the surface of the side plate 12. A flattening mechanism 2 is slidably connected inside the sliding groove 14. An inclined support plate 3 is rotatably connected to the pad 11 through a rotating shaft.
[0028] The flattening mechanism 2 includes a locking block 21 that is slidably engaged inside the slide groove 14. A moving strip 22 is fixedly attached to the surface of the locking block 21. The side of the moving strip 22 closest to the pad 11 is fixedly connected to the pressing plate 23. A pull rod 24 is fixedly connected to the side of the moving strip 22 away from the pad 11.
[0029] The effects achieved by the above components are as follows: the snap-fit design of the locking block 21 and the slide groove 14 allows the flattening mechanism 2 to slide smoothly along the slide groove 14 of the side plate 12, thereby realizing the movement of the flattening mechanism 2 at different positions above the pad plate 11; the moving bar 22 serves as a connecting component, firmly connecting the locking block 21, the pressing plate 23 and the pull rod 24, providing structural support for subsequent flattening operations; the pull rod 24 facilitates the user to apply force, and by pulling the pull rod 24, the entire flattening mechanism 2 can be easily moved, making operation convenient.
[0030] Specifically, the pressure plate 23 includes a telescopic spring 231, which is fixedly connected to the side surface of the moving bar 22 near the pad 11, and the end of the telescopic spring 231 away from the moving bar 22 is fixedly connected to the flat plate 232.
[0031] The aforementioned components achieve the following effects: The telescopic spring 231 possesses excellent elasticity and can automatically adjust the pressure between the smoothing plate 232 and the drawing according to the unevenness of the drawing surface during the flattening process. When the smoothing plate 232 contacts a raised portion of the drawing surface, the telescopic spring 231 is compressed, reducing the pressure of the smoothing plate 232 on that portion and preventing excessive pressure that could damage the drawing; when the smoothing plate 232 contacts a recessed portion of the drawing, the telescopic spring 231 extends, increasing the pressure of the smoothing plate 232 on that portion, ensuring the drawing is evenly smoothed. The smoothing plate 232 is made of soft and elastic silicone material, which can closely conform to the drawing surface, dispersing pressure during the flattening process and effectively preventing the formation of new wrinkles in the drawing. It achieves good flattening results for both thin and thick drawings.
[0032] Specifically, the inclined support plate 3 includes a rotating rod 31. A connecting groove is provided on the side surface of the pad 11 away from the fixing clamp 13. The rotating rod 31 is rotatably connected inside the connecting groove. An adjusting plate 32 is fixedly connected to the outer surface of the rotating rod 31. Both ends of the rotating rod 31 are fixedly connected to a fixing plate 33 through the side plate 12.
[0033] The effects achieved by the above components are as follows: the rotating connection design between the rotating rod 31 and the connecting groove of the pad 11 provides a rotating basis for the angle adjustment of the pad 11; the adjusting plate 32 is fixed on the outer surface of the rotating rod 31, and the user can easily drive the rotating rod 31 to rotate by operating the adjusting plate 32, thereby changing the tilt angle of the pad 11; the fixing plate 33 is fixed at both ends of the rotating rod 31, which on the one hand enhances the stability of the rotating rod 31 when rotating, and on the other hand makes it easier for the user to apply force when adjusting the angle, and also plays a certain limiting role to prevent the rotating rod 31 from rotating excessively and detaching from the side plate 12.
[0034] Specifically, a pull block 321 is fixedly connected to the lower end of the surface of the adjustment plate 32, and the outer surface of the pull block 321 is provided with anti-slip texture.
[0035] The effects achieved by the above components are as follows: the pull block 321 provides the user with a convenient gripping point. By pulling the pull block 321, the adjustment plate 32 and the rotating rod 31 can be rotated more easily and accurately. The anti-slip texture design increases the friction between the hand and the pull block 321, ensuring that the user can apply force stably even when the hand is wet or oily, avoiding slippage, and making the adjustment of the tilt angle of the pad 11 safer and more reliable.
[0036] Specifically, the fixing clip 13 includes a mounting plate 131 fixedly connected to the surface of the pad 11, and a metal clamp 132 is fixedly connected to the surface of the mounting plate 131.
[0037] The above components achieve the following effects: the mounting plate 131 serves as a connection and fixation mechanism, securely mounting the metal clamp 132 onto the surface of the pad 11; the metal clamp 132 has a certain degree of elasticity, which can firmly clamp one end of the drawing, preventing the drawing from shifting during the flattening operation, ensuring the stability of the drawing during the flattening process, and also making it easy for the user to quickly fix the drawing onto the pad 11.
[0038] Specifically, a limit block 111 is provided on the surface of the pad 11, and the top of the pad 11 is fixedly connected to the suspension block 112.
[0039] The effects achieved by the above components are as follows: the limiting block 111 is made of rubber, which has a certain elasticity and friction, and can limit the drawing placed on the pad 11 to prevent the drawing from sliding freely on the surface of the pad 11, and ensure that the drawing maintains an accurate position during the flattening process; the hanging block 112 makes it convenient to store and hang the device when not in use. Users can hang the flattening clamp on the wall, tool rack, etc., to save space and make it easy to quickly retrieve next time.
[0040] Specifically, a connecting rod 15 is fixedly connected between the two side plates 12, and a scale 16 is provided on the side of each side plate 12.
[0041] The effects achieved by the above components are as follows: the connecting rod 15 connects the two side plates 12, enhancing the overall stability of the clamping device 1. During the operation of the flattening mechanism 2 moving and the tilting support plate 3 adjusting the angle, it effectively prevents the side plates 12 from deforming or shaking, ensuring the reliability of the entire flattening clamp during use. The scale 16 on the sides of the two side plates 12 can help users quickly measure the dimensions of the drawings. In engineering cost work, it is convenient for users to perform relevant calculations and operations according to the dimensions of the drawings, improving work efficiency.
[0042] Working principle: When using the anti-wrinkle flattening clamp for engineering cost drawings, first place one end of the drawing between the metal clamps 132 of the fixing clamp 13. The elasticity of the metal clamps 132 will fix the drawing to the pad 11, while the limiting block 111 further limits the drawing to prevent it from sliding. Then, according to the actual viewing needs, pull the pull block 321, which will drive the adjusting plate 32 and the rotating rod 31 to rotate, so that the pad 11 is adjusted to a suitable tilt angle. The fixing plate 33 ensures that the rotation process is stable and the angle adjustment is precise.
[0043] Next, grasp the pull rod 24 and pull it to drive the flattening mechanism 2 to slide within the slide groove 14. At this time, the smoothing plate 232 of the pressing plate 23 moves against the surface of the drawing under the action of the telescopic spring 231, performing a uniform pressing and smoothing operation on the drawing. During the flattening process, the smoothing plate 232 will automatically adjust the pressure according to the unevenness of the drawing surface through the telescopic spring 231 to ensure that the drawing is subjected to uniform force and effectively prevent the formation of new wrinkles. The scale 16 on the two side plates 12 can be used to assist in measuring the dimensions of the drawing at any time, meeting the measurement needs in engineering cost work. When not in use, the flattening clamp can be suspended and stored by the hanging block 112 to save space.
