Description

Technical Field

[0001] The utility model relates to the technical field of drawing comparison, in particular to a drawing comparison device. Background Art

[0002] As we all know, drawings are the main way for design companies to express design ideas and conduct technical exchanges with construction companies. They are widely used in various industries such as architectural design and mechanical manufacturing. Design drawings often need to go through multiple repeated modifications and verification processes from design to construction and acceptance. Therefore, there are many versions of the same design drawings, which makes drawing management complicated. In many links, the wrong version of the design drawing may be used at any time due to failure to accurately identify the differences between different versions of the design drawings, resulting in varying degrees of losses. Therefore, drawing comparison technology is particularly important.

[0003] After searching, the utility model patent with Chinese publication number CN217117904U discloses a drawing comparison device for mold design, which includes two support rods, a display board is fixedly connected between the front sides of the two support rods, both sides of the top and bottom of the display board are fixedly connected with fixed blocks, and the left and right fixed blocks are fixedly connected with sliding rods between the opposite sides, and a clamping mechanism is slidably connected between the surfaces of the two sliding rods. By setting the clamping mechanism, the fixed rod is pulled, and the movement of the limit plate is driven by the elastic force of the spring, and the drawing is placed on the surface of the display board, thereby limiting the drawing. By setting a damping shaft, the connection between the placement plate and the support plate is connected by the damping shaft, thereby increasing the friction during rotation. Through the connecting rod, the slider slides in the slide groove to drive the movement of the connecting rod, thereby supporting the placement plate.

[0004] Although the above technical solution solves the problem of drawing support, in the above technical solution, when it is necessary to compare two roughly identical drawings or relatively complex drawings, it is very tiring to observe with the naked eye, and it is impossible to find the differences between the two drawings at the same time. In order to reduce the time for operators to compare drawings and increase work efficiency during comparison, a drawing comparison device is needed. Utility Model Content
