Description

Technical Field

[0001] This utility model is an architectural design drawing device, belonging to the technical field of drawing devices. Background Technology

[0002] Architectural design refers to the process by which designers, before construction begins, comprehensively envision and formulate solutions to potential problems that may arise during construction and use, based on the construction task. These solutions are then expressed in drawings and documents, serving as a common basis for material preparation, construction organization, and cooperation among various trades during the production and construction process. In the initial stage of architectural design drawing, designers need to create numerous sketches. During this period, due to the need for extensive revisions to the architectural plans, the surveyed red line map is used as the base map, followed by tracing. Tracing involves using transparent thin paper (such as tracing paper) to trace the original drawing. The resulting drawings can be freely redrawn and modified without affecting the reuse of the original base map.

[0003] The existing patent CN 221340007 U discloses an architectural design drawing device. In this patent, a rotating rod is used to reset and press the cover plate to the base drawing, a positioning claw is used to fit the drawing paper on the top of the cover plate, and a positioning plate, several through holes, insertion holes, a rotating arm, a plug rod, a spring, and a limit cap are used to tilt the tabletop and fix the tilted tabletop. However, this method of adjusting the angle of the tabletop requires adjustment of both sides of the tabletop, and the adjusted angles must be consistent. After the adjustment is completed, a series of steps are required to fix the angle of the tabletop. The operation is too complicated. Moreover, the adjustment of the positioning plate and through holes can only adjust a few angles, which is inconvenient in actual use. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an architectural design drawing device.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A drawing device for architectural design includes a support frame. Two support frames are fixed to one side of the top of the support frame. A tabletop is movably connected to the support frames. A movable cavity is opened inside the rear side of the support frame. An adjustment mechanism is provided in the movable cavity. The top of the adjustment mechanism extends through the support frame and connects to the bottom of the tabletop. A groove is opened in the center of the top of the tabletop. A cover plate is provided in the groove. A limiting component that cooperates with the cover plate is provided on the top of the tabletop. Paper pressing components are provided around the top of the cover plate.

[0007] Furthermore, the adjustment mechanism includes a motor fixed to the rear side of the bracket. The output end of the motor is connected to a rotating rod. The end of the rotating rod passes through the movable cavity and is connected to the end of a first bevel gear. The first bevel gear meshes with a second bevel gear.

A moving block is threaded onto the outer surface of the threaded rod. A push rod is fixed to the top of the moving block. A slider is provided at each of the left and right ends of the moving block. A vertical groove that cooperates with the slider is opened on each of the inner walls of the two sides of the movable cavity.

[0008] Furthermore, a movable groove is provided at the bottom of the desktop, and a sliding groove is provided on each of the inner walls of the movable groove. The push rod extends through to the top of the bracket and is provided with a sliding rod. The top of the push rod extends through the movable groove, and the two ends of the sliding rod are slidably connected in the sliding grooves on both sides.

[0009] Furthermore, the movable block has a threaded hole inside that mates with the threaded rod, and the push rod has a through hole inside that mates with the threaded rod.

[0010] Furthermore, the paper pressing assembly includes a fixing frame fixed to the top of the cover plate, a rotating groove is provided at the end of the fixing frame, a pressure plate is connected to the rotating groove through a connecting shaft, a spring is connected between the pressure plate and the fixing frame, a rubber pad is provided at the bottom of the pressure plate, and a handle is provided at the top of the pressure plate.

[0011] Furthermore, the limiting component includes a fixed shaft fixed to the top of the desktop, a limiting rod rotatably connected to the fixed shaft, and a U-shaped frame that cooperates with the limiting rod on the top side of the cover plate. The openings of the two U-shaped frames on the front side of the cover plate are opposite to those of the two U-shaped frames on the rear side.

[0012] The beneficial effects of this utility model are:

[0013] By setting up a cover plate, a limiting component, and a paper pressing component, the cover plate can position the base drawing, the limiting component can fix the position of the cover plate to prevent its movement from causing the base drawing to move, and the paper pressing component can fix the tracing paper located on top of the cover plate to facilitate drawing and prevent displacement of the two from affecting the accuracy of the drawing.

[0014] The adjustable mechanism allows for the tilt angle of the desktop to be adjusted, enabling drafters to draw at a distance even while seated. Furthermore, the mechanism allows for the adjustment of the entire desktop angle with a single motor drive, eliminating the need for multiple manual adjustments and making it more convenient to operate. Additionally, the adjustable mechanism allows for use at any angle of the desktop, increasing its usability.

[0015] The push rod has a through hole inside. When the threaded rod drives the moving block and the push rod to move downward, the threaded rod will move in the through hole inside the push rod, thus not affecting the operation of the entire adjustment assembly.

[0016] By setting the limiting component, the position of the cover plate can be fixed to prevent the position of the base plate from moving due to the movement of the cover plate.

[0017] The paper-pressing assembly can be used to fix the tracing paper located on top of the cover plate, thereby improving the accuracy of the drawing. Attached Figure Description

[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] Please see Figure 1-6 This utility model provides a technical solution for an architectural design drawing device, including a bracket 1. Two support frames 2 are fixed to one side of the top of the bracket 1. A tabletop 3 is movably connected to the support frame 2. A movable cavity 4 is opened inside the rear side of the bracket 1. An adjustment mechanism is provided in the movable cavity 4. The top of the adjustment mechanism extends through the bracket 1 and connects to the bottom of the tabletop 3. A groove 26 is opened in the middle of the top of the tabletop 3. A cover plate 17 is provided in the groove 26. A limiting component that cooperates with the cover plate 17 is provided on the top of the tabletop 3. Both the groove 26 and the cover plate 17 in the middle of the tabletop 3 are transparent. Made of transparent materials such as resin, plexiglass, and transparent acrylic, the tabletop 3 allows light to pass through, facilitating the presentation of the background pattern. The top of the cover plate 17 is equipped with paper-pressing components. Through the arrangement of the cover plate 17, the limiting components, and the paper-pressing components, the cover plate 17 can position the background pattern, the limiting components can fix the position of the cover plate 17 to prevent it from moving and causing the background pattern to move, and the paper-pressing components can fix the tracing paper located on top of the cover plate 17 for easy drawing and to prevent displacement of the two from affecting the accuracy of the drawing.

[0028] See Figure 4 and Figure 5The adjustment mechanism includes a motor 5 fixed to the rear side of the bracket 1. The output end of the motor 5 is connected to a rotating rod 6. The end of the rotating rod 6 passes through the movable cavity 4 and connects to the end of a bevel gear 7. The bevel gear 7 meshes with a bevel gear 8. One end of the bevel gear 8 is rotatably connected to the movable cavity 4, and the other end is connected to a threaded rod 9. A moving block 10 is threaded onto the outer surface of the threaded rod 9. A push rod 11 is fixed to the top of the moving block 10. A slider 12 is provided at each of the left and right ends of the moving block 10. A vertical groove 13 that cooperates with the slider 12 is opened on each of the inner walls of the movable cavity 4. A moving groove 14 is opened at the bottom of the tabletop 3. A sliding groove 15 is provided on each of the inner walls of the moving groove 14. The push rod 11 passes through to the top of the bracket 1 and is provided with a sliding rod 1. 6. The top end of the push rod 11 extends into the moving groove 14, and the two ends of the slide rod 16 are slidably connected in the sliding grooves 15 on both sides. Since only the drawing and the cover plate 17 are placed on the top of the desktop 3, and the weight of the three is relatively light, the meshing resistance between the threaded rod 9 and the moving block 10 can support the weight of the desktop 3 and the drawing, so that the adjusted desktop 3 will not move arbitrarily. In addition, according to the different heights of the draftsmen, a limiting component that cooperates with the push rod 11 can be set on the bracket 1 to limit and fix the adjusted push rod 11. The limiting component can be any conventional limiting component in the prior art. Through the setting of the adjustment mechanism, the tilt angle of the desktop 3 can be adjusted, so that the draftsmen can draw drawings at a relatively far position even when sitting. At the same time, the setting of the adjustment mechanism can complete the angle adjustment of the entire desktop 3 by driving the motor 5 once, which is more convenient to operate.

[0029] See Figure 4 The movable block 10 has a threaded hole inside that mates with the threaded rod 9, and the push rod 11 has a through hole inside that mates with the threaded rod 9. When the threaded rod 9 moves the movable block 10 and the push rod 11 downwards, the threaded rod 9 will move within the through hole inside the push rod 11, thus not affecting the operation of the entire adjustment assembly.

[0030] See Figure 6 The paper pressing assembly includes a fixing frame 18 fixed to the top of the cover plate 17. The end of the fixing frame 18 is provided with a rotating groove. A pressure plate 19 is connected to the rotating groove through a connecting shaft 20. A spring 21 is connected between the pressure plate 19 and the fixing frame 18. A rubber pad 22 is provided at the bottom of the pressure plate 19. A handle is provided at the top of the pressure plate 19. By setting up the paper pressing assembly, the tracing paper located on the top of the cover plate 17 can be fixed, thereby improving the accuracy of drawing.

[0031] See Figure 1, Figure 2 and Figure 3 The limiting component includes a fixed shaft 23 fixed to the top of the desktop 3, and a limiting rod 25 rotatably connected to the fixed shaft 23. The top side of the cover plate 17 is provided with a U-shaped frame 24 that cooperates with the limiting rod 25. The openings of the two U-shaped frames 24 on the front side of the cover plate 17 are opposite to those of the two U-shaped frames 24 on the rear side. By setting the limiting component, the position of the cover plate 17 can be fixed to avoid the movement of the cover plate 17 causing the position of the base map to move.

[0032] In use, first, rotate the limiting rod 25 to rotate it out of the U-shaped frame 24. Then, pull the cover plate 17 upward to lay the bottom plate flat in the groove 26 at the top of the table 3. Then, reset the cover plate 17 in the groove 26 so that the bottom plate is between the groove 26 and the cover plate 17. The bottom end of the cover plate 17 can press the bottom plate to prevent it from shifting. Next, rotate the limiting rod 25 in the opposite direction so that the limiting rod 25 rotates into the U-shaped frame 24 at the top of the cover plate 17 to limit the position of the cover plate 17.

[0033] Next, after covering the top of the cover plate 17 with tracing paper, activate the paper pressing assembly to press the tracing paper on the top of the cover plate 17. The process of covering the tracing paper is as follows: pull the handle on the top of the pressure plate 19 towards the fixing frame 18. The handle drives the pressure plate 19 to rotate around the connecting shaft 20. When the pressure plate 19 rotates, it will stretch the spring 21. Then, place the tracing paper on the top of the cover plate 17. Next, release the force of pulling the handle. Under the action of the spring 21, the pressure plate 19 and the rubber pad 22 will return to their original positions, so that the rubber pad 22 is fixed on the top of the tracing paper. Next, operate the other pressure plates 19 to rotate away from the top of the cover plate 17. Then, straighten the tracing paper. Then, release the handle. Under the action of the spring 21, the pressure plate 19 and the rubber pad 22 will reset to press the tracing paper. After all four ends of the tracing paper are positioned, tracing can begin.

[0034] During the drawing process, to facilitate the drawing, the adjustment mechanism can be driven to adjust the tilt angle of the desktop 3. That is, the motor 5 is started, and the output end of the motor 5 drives the rotating rod 6 and the bevel gear 7 to rotate. The bevel gear 7 drives the bevel gear 8 that meshes with it to rotate. The bevel gear 8 drives the threaded rod 9 to rotate. Under the constraint of the slider 12 and the vertical groove 13, the rotation of the threaded rod 9 drives the moving block 10 to move up and down. When the moving block 10 moves up and down, it will drive the push rod 11 at the top of the moving block 10 to move up and down. When the push rod 11 moves up, the push rod 11 will drive one end of the desktop 3 to rotate around the support frame 2. At this time, the top of the push rod 11 moves in the moving groove 14 at the bottom of the desktop 3, thereby adjusting the desktop 3 to any tilt angle.

[0035] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
