Description

Technical Field

[0001] This utility model relates to the technical field of drawing review auxiliary equipment, specifically a drawing comparison device for technical review. Background Technology

[0002] In fields such as engineering construction and machinery manufacturing, technical review is a crucial step in ensuring project quality and accuracy. A common task is to compare and review different versions of drawings. This comparison helps identify modifications, discrepancies, and errors in the drawings, ensuring the smooth progress of subsequent production and construction.

[0003] When comparing drawings, staff typically lay two copies flat on a table and visually compare them. However, this method allows the drawings to easily move on the table, affecting the accuracy of the comparison. During the comparison process, it is difficult to accurately locate the corresponding positions of the two drawings, requiring repeated adjustments to the line of sight and drawing positions. This not only increases the workload but also reduces review efficiency. Therefore, those skilled in the art have provided a drawing comparison device for technical review to address these problems.

[0024] It is easy to understand that according to the technical solution of the present utility model, without changing the essential spirit of the present utility model, those of ordinary skill in the art can propose various structural ways and implementation ways that can be mutually replaced. Therefore, the following detailed embodiments and the accompanying drawings are only exemplary descriptions of the technical solution of the present utility model, and should not be regarded as all of the present utility model or as a limitation or restriction on the technical solution of the present utility model.

[0025] A drawing comparison device for technical review, refer to Figure 1-3 ,include:

[0026] The placement board 1 has two placement areas 11 for holding two sets of drawings to be compared. Furthermore, each placement area 11 has a rectangular slot, into which a pressure plate 3 is inserted. This design helps to position the drawings. The interlocking of the rectangular slots and the pressure plate 3 not only precisely limits the placement range of the drawings, preventing them from shifting due to external force, but also allows reviewers to quickly locate the corresponding areas of the two drawings during comparison, reducing misjudgments caused by inaccurate drawing positions and greatly improving the efficiency and accuracy of technical review.

[0027] The slider 2 is horizontally slidably positioned between the two placement areas 11. A horizontal groove is provided on the placement plate 1 between the two placement areas 11, and the slider 2 slides within this groove. The vertical cross-section of the slider 2 is convex ("U"-shaped). This convex shape prevents the slider 2 from falling out of the groove, ensuring stable horizontal sliding within it. This stable sliding structure allows the slider 2 to move flexibly between the two placement areas 11, enabling auditors to easily adjust its position according to different comparison points on the drawing. This allows for precise comparison of any area of ​​the drawing, meeting the needs of different drawings and different audit focuses.

[0028] The pressure plate 3, elastically positioned perpendicular to the placement area 11, is used to fix the drawings, and one side indicates the corresponding positions of the two drawings. It has a clearance hole 31. Furthermore, the slider 2 has two sleeves, with vertical rods inserted inside. The tops of the vertical rods are fixed to the pressure plate 3, and springs are fitted onto the vertical rods. The springs are located inside the sleeves and press downwards against the vertical rods. Through the elastic action of the springs, the pressure plate 3 always has a downward pressing tendency, thus fixing the drawings to the placement area 11. The elastic pressure of the springs can be automatically adjusted according to the thickness of the drawings, firmly fixing them in place to prevent movement during comparison without damaging them due to excessive pressure. This is especially suitable for reviewing thin or valuable drawings. Simultaneously, the indicator function of the pressure plate 3 can intuitively mark the corresponding positions of the two drawings, making it easy for reviewers to see and reducing visual fatigue during comparison.

[0029] Rotating block 4 is rotatably mounted on slider 2. When the drawing is fixed, the upper surface of rotating block 4 abuts against pressure plate 3. The top of rotating block 4 is designed with two symmetrical upward-protruding arc surfaces, and control rod 5 is fixed at the intersection of the two arc surfaces. This arc surface design allows for a smooth change in the height at which rotating block 4 abuts against pressure plate 3 when rotating. The symmetrical arc surface design makes the lifting or lowering of pressure plate 3 by rotating block 4 more stable and gentle during rotation, avoiding impact on the drawing or device components due to sudden height changes, extending the service life of the device, and also making operation smoother and less strenuous for reviewers.

[0030] The control lever 5 is fixed on the rotating block 4 and passes through the clearance hole 31, which can limit the rotation angle of the control plate.

[0031] When adjusting the position of the pressure plate 3, move the control lever 5 to the side to be adjusted. The height of the rotating block 4 will rise and lift the pressure plate 3, which can be separated from the drawing to avoid friction on the drawing surface and causing the drawing to shift. The indicator position of the pressure plate 3 can also be adjusted to facilitate the comparison of information at different positions on the drawing and facilitate technical review.

[0032] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
