[0004] The above solution solves the technical problems mentioned in the background art. However, in practical applications, the above solution still has certain defects. For example, if the size of the drawing to be drawn is large, after the drawing is partially completed, the drawing person needs to move the drawing paper to the center of the drawing board. However, the paper that is moved out is exposed on the outside of the drawing board in an extended shape, which makes it easy to be contaminated and thus damage the drawing. Utility Model Content

[0005] The purpose of this utility model is to provide an engineering drawing device for construction engineering management to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a construction engineering management engineering drawing device, including a base and a drawing board, wherein both sides of the drawing board are provided with clamping components, and the drawings are fixed on the surface of the drawing board by the clamping components;

[0007] The drawing board is equipped with unwinding and rewinding components on both sides.

[0008] The unwinding assembly includes a baffle and an unwinding shaft. The cylindrical drawing is movably inserted into the shaft of the unwinding shaft, and the winding assembly winds up the drawing.

The bottom of the pressure plate has a second groove, in which an electromagnet is fixed. The bottom surface of the electromagnet is flush with the bottom surface of the pressure plate.

[0013] Preferably, the winding assembly includes two L-shaped frames, with a roller movably connected between the tops of the L-shaped frames. A first plane is formed at the top of the middle part of the roller, a pressure shaft is provided at the top of the roller, and a second plane is formed at the bottom of the pressure shaft.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This construction engineering management drawing device is equipped with a clamping component and a rewinding component. When the drawing on the drawing board is completed and the blank area of ​​the paper needs to be moved to the center of the drawing board for redrawing, the rewinding component rewinds the completed drawing. After rewinding, the clamping component fixes the drawing on the drawing board, thereby achieving the goal of rewinding the moved-out drawing together, avoiding contamination of the drawing, and preventing damage to the drawing.

[0019] In addition, the device is equipped with a storage slot, a stop block, and a tool storage cavity.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1-4 As shown, this utility model provides a technical solution: a construction engineering management drawing device, including a base 1, a drawing board 2, and a controller. Clamping components 4 are provided on both sides of the drawing board 2 to fix the drawing onto the surface of the drawing board 2. Unwinding components and rewinding components 6 are respectively provided on both sides of the drawing board 2. Wherein, as... Figure 1 As shown, the unwinding assembly includes a baffle 501 and an unwinding shaft 502. The roll-shaped drawing is movably inserted into the shaft of the unwinding shaft 502, and the winding assembly 6 winds up the completed drawing.

[0028] To adjust the angle of drawing board 2, thus facilitating drawing on the paper, such as... Figure 1 and Figure 2As shown, a storage slot is provided on the top of the base 1. A movable shaft is movably connected between the side walls of the storage slot facing the drafter. The bottom of the drawing board 2 is fixed to the movable shaft. A driving component is provided on one side of the movable shaft. The driving component drives the movable shaft to rotate, thereby adjusting the angle of the drawing board 2 and allowing the drawing board 2 to be stored in the storage slot after drawing. A stop block 3 is fixed at the bottom of the storage slot. When the drawing board 2 is stored in the storage slot, the stop block 3 supports the drawing board 2. A tool placement cavity 301 for placing drawing tools is provided on the top of the stop block 3. In this way, the drafter can place the drawing tools in the tool placement cavity 301 during or after drawing, so that the drafter does not need to carry the drawing tools with a tool bag, which increases the convenience of using the device.

[0029] Understandably, in existing technologies, the drawing board 2 is usually fixed after the angle of the drawing board 2 is adjusted by a support rod or an electric telescopic rod. This reduces the space required for the storage compartment due to the addition of related components.

[0030] In this plan, such as Figure 3 As shown, the driving component includes a worm gear 7 fixed on the movable shaft. A mounting box is fixed on the side of the base 1, and a worm is movably connected to the bottom of the mounting box. The worm gear 7 meshes with the worm. Thus, when the angle of the drawing board 2 needs to be adjusted, the drawer rotates the knob on the movable shaft, and the worm drives the worm gear 7 and the drawing board 2 to rotate. It is understood that because the worm and the worm gear 7 have a self-locking property, the disorderly rotation of the drawing board 2 can be prevented, reducing the number of supporting components for the drawing board 2 and thus increasing the usable space of the storage slot.

[0031] like Figure 3 As shown, the clamping assembly 4 includes a U-shaped frame 401, a pressure plate 402 is movably disposed at the bottom of the U-shaped frame 401, and a plurality of first insert shafts 403 are fixed at the top of the pressure plate 402. The first insert shafts 403 are movably inserted into the U-shaped frame 401, and a plurality of first springs are fixed between the pressure plate 402 and the U-shaped frame 401. In a specific embodiment of this solution, two first insert shafts 403 are provided, symmetrically distributed on both sides of the U-shaped frame 401, and the first insert shafts 403 are located in the spiral coil of the first spring. A first groove is provided on the top of the drawing board 2, and a magnetic block is fixed in the first groove. The top surface of the magnetic block is flush with the top surface of the drawing board 2. A second groove is provided on the bottom of the pressure plate 402, and an electromagnet 404 is fixed in the second groove. The bottom surface of the electromagnet 404 is flush with the bottom surface of the pressure plate 402.

[0032] In this way, in the initial state or when the completed drawing is being rolled up, the electromagnet 404 is de-energized and demagnetized. At this time, under the elastic force of the first spring, there is a gap between the pressure plate 402 and the drawing board 2 for the drawing to pass through. After the drawing is laid out, the controller controls the electromagnet 404 to be energized and magnetized. The electromagnet 404 and the magnetic block attract each other. At this time, the first spring is stretched by force and the pressure plate 402 moves downward to squeeze the drawing, thereby fixing the two sides of the drawing.

[0033] like Figure 3 and Figure 4 As shown, the winding assembly 6 includes two L-shaped frames 601, with a roller 602 movably connected between the tops of the L-shaped frames 601. A first plane is formed at the top of the middle part of the roller 602, and a pressure shaft 603 is provided at the top of the roller 602. A second plane is formed at the bottom of the pressure shaft 603. The first plane and the second plane are adapted to each other. A plurality of screws 604 are fixed at the bottom end of the pressure shaft 603. After the screws 604 move through the roller 602, nuts are screwed onto their rods. In a specific embodiment of this solution, the number of screws 604 is set to two, symmetrically distributed on both sides of the pressure shaft 603.

[0034] Specifically, the process of rolling up the completed drawing is as follows: the drawing is passed through the gap formed between the first plane and the second plane (the drawing is located between the two screws 604), the drafter rotates the two nuts to fix the roller 602 and the pressure roller 603, and when rolling, the knob on the outside of the roller 602 is turned to rotate the roller 602 and the pressure roller 603, thereby realizing the rolling up of the completed drawing.

[0035] To prevent the rolled-up drawings from being rotated haphazardly, such as Figure 4 As shown, an L-shaped frame 601 extends from one side of the roller 602. An arc-shaped anti-slip block 605 is provided on the roller 602 extending from the L-shaped frame 601. A second insert shaft 606 is fixed to the top of the arc-shaped anti-slip block 605. The second insert shaft 606 is movably inserted into the L-shaped frame 601, and a second spring is fixed between the L-shaped frame 601 and the arc-shaped anti-slip block 605.

[0036] In this way, when the roller 602 and the pressure roller 603 are rotated, due to the large rotational force, the second spring contracts, and the arc-shaped anti-slip block 605 moves upward to roll up the completed drawing. After the rotation stops, the second spring returns to its original position, and the bottom arc-shaped plate of the arc-shaped anti-slip block 605 is pressed against the top shaft of the roller 602 extending from the L-shaped frame 601. Under the action of friction, the roller 602 is positioned.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
