Technical Field

[0001] This utility model relates to the field of auxiliary drawing technology for interior design, and in particular to an auxiliary drawing device for interior design. Background Technology

[0002] Interior design is the process of creating a functional, comfortable, and aesthetically pleasing indoor environment that meets people's material and spiritual needs, based on the building's usage, environment, and relevant standards, using material and technical means and architectural design principles. This spatial environment not only has practical value and meets the corresponding functional requirements, but also reflects spiritual factors such as historical context, architectural style, and environmental atmosphere. Auxiliary drawing devices are needed to assist in the interior design drawing process.

[0003] A search revealed that patent CN216220641U discloses an auxiliary drawing device for interior design; however, this auxiliary drawing device has the following shortcomings in use:

[0004] While the auxiliary drawing device can help people draw on paper, it is inconvenient to manually roll up the drawing paper after the drawing is finished. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that while existing auxiliary drawing devices can help people draw on paper, they still require manual winding of the drawing paper after the drawing is finished, which is inconvenient. Therefore, this utility model proposes an auxiliary drawing device for interior design.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An auxiliary drawing device for interior design includes a table frame and a tabletop for placing drawing paper. The inner walls of both sides of the table frame are rotatably connected with rotating rods for adjusting the angle of the tabletop. The ends of the two rotating rods that are close to each other are fixedly connected to the two sides of the tabletop.

[0008] A winding mechanism, located on one side of the table frame, is used to wind up the drawing paper;

[0009] A fixing mechanism is installed on the table frame to fix the angle of the tabletop;

[0010] The pressing mechanism is installed on the table to press down and fix the two ends of the drawing paper.

[0011] In one possible design, the winding mechanism includes a frame, a motor, a circular plate, and two winding rods. One side of the frame is fixedly connected to one side of the table frame, one side of the motor is fixedly connected to the inner wall of one side of the frame, the output end of the motor passes through one side of the frame and is fixedly connected to the center of one side of the circular plate, and the two winding rods are both located on one side of the circular plate. The space between the two winding rods is the paper feeding port.

[0012] In one possible design, the fixing mechanism includes two semicircular plates and two threaded rods. The tops of the two semicircular plates are fixedly connected to the bottom sides of the tabletop, respectively. Multiple insertion holes are provided on the semicircular plates. Threaded holes are provided on both sides of the table frame. The two threaded rods are threadedly connected to the two threaded holes, respectively. One end of the threaded rod is inserted into the insertion hole, and a second knob is fixedly provided at one end of the threaded rod to facilitate its rotation.

[0013] In one possible design, the pressing mechanism includes two connecting plates, two fixed plates, and two pressure plates. The connecting plates are L-shaped, and one side of the tabletop has a movable groove to facilitate the movement of the connecting plates. One end of each of the two connecting plates is slidably connected to the inner wall of the movable groove. A limiting groove is provided on the bottom inner wall of the movable groove, and a limiting block is slidably connected to the inner wall of the limiting groove to prevent the connecting plates from disengaging from the movable groove. The top of the limiting block is fixedly connected to the bottom of the connecting plate. One side of each of the two fixed plates is fixedly connected to one side of the connecting plate. The two pressure plates are located below the two fixed plates. Multiple springs are fixedly installed on the top of the pressure plates, and the tops of the multiple springs are fixedly connected to the bottom of the fixed plates. A through hole is provided on the fixed plate, and a pull rod is slidably connected to the inner wall of the through hole. The bottom of the pull rod is fixedly connected to the top of the pressure plate. A rubber pad is fixedly installed on the bottom of the pressure plate.

[0014] In one possible design, a movable groove is provided on one side of the circular plate, and two movable blocks are slidably connected to the inner wall of the movable groove. One end of each of the two winding rods is fixedly connected to one side of the two movable blocks. The same bidirectional lead screw is rotatably connected to the top and bottom inner walls of the movable groove. A bearing is embedded in one side of the circular plate, and a first knob is fixedly installed on the inner wall of the inner ring of the bearing. The first knob is T-shaped, and its bottom end is fixedly connected to the top end of the bidirectional lead screw. A lead screw nut is embedded in one side of the movable block, and the lead screw nut is threadedly connected to the bidirectional lead screw.

[0015] In one possible design, a connecting strip is fixedly provided on one side of the table frame, and multiple storage tubes for holding rolled-up drawing paper are fixedly provided on one side of the connecting strip.

[0016] In one possible design, a placement board for placing drawing tools is fixedly installed on the other side of the table frame.

[0017] In this application, during use, the drawing paper is laid flat on the table surface, stretched straight to both sides, and the two levers are held with both hands. The levers are lifted upwards, and the pressure plates are moved towards the paper (the connecting plate slides within the movable groove), causing the two pressure plates to move to both ends of the paper. The levers are released, and the springs push the pressure plates downwards, with the rubber pads tightly adhering to the edges of the paper to prevent slippage. When the table angle needs to be adjusted, the second knob of the two threaded rods is rotated counterclockwise to disengage them from the insertion holes of the semi-circular plate. The edge of the table is held, and the table is rotated. The table is rotated via the rotating rod to the desired tilt angle, aligning the insertion holes with the threaded rods. Then, the second knob is rotated, causing the threaded rods to rotate within the threaded holes, inserting one end of the threaded rod into the corresponding insertion hole, thus fixing the angle of the table. The placement plate can be used to place drawing tools, such as pens, etc. After drawing, pull the lever to release the pressure on the drawing paper and remove it. When it is time to rewind, rotate the first knob on the circular plate to drive the bidirectional lead screw to rotate, causing the two moving blocks to move synchronously away from or towards each other in the moving slot. Adjust the distance between the two winding rods according to the thickness of the drawing paper to ensure that the paper roll can be stably placed into the paper feeding slot. Then, insert one end of the drawing paper into the paper feeding slot formed by the two winding rods and hold it. Start the motor. The motor output will drive the circular plate and winding rods to rotate, and at the same time, drive the drawing paper to rotate, thus rewinding the drawing paper. After rewinding, turn off the motor, hold the rolled-up drawing paper and pull it out from one end of the winding rod. The rewound drawing paper can be placed in the storage tube for storage. Note that the motor needs to be powered by an external power source and controlled by an external controller.

[0018] The beneficial effects of this utility model are as follows:

[0019] In this utility model, the auxiliary drawing device for interior design uses a winding mechanism to start a motor. The motor output drives the circular plate and winding rod to rotate, which in turn drives the drawing paper to rotate, thereby winding the drawing paper.

[0020] In this utility model, the auxiliary drawing device for interior design, through a fixing mechanism, when the angle of the table needs to be adjusted, rotate the second knob of the two threaded rods counterclockwise to disengage them from the insertion holes of the semicircular plate, hold the edge of the table, rotate the table, and the table rotates through the rotating rod to make the table tilt to the required angle and align the insertion holes with the threaded rods. Then rotate the second knob, and the second knob drives the threaded rods to rotate in the threaded holes, so that one end of the threaded rod is inserted into the corresponding insertion hole, thereby fixing the angle of the table.

[0021] In this utility model, the auxiliary drawing device for interior design uses a pressing mechanism to lay the drawing paper flat on the table surface, straighten the paper to both sides, hold the two pull rods with both hands, lift the pressure plate upwards and move it towards the paper (the connecting plate slides in the movable groove), so that the two pressure plates move to both ends of the paper. Release the pull rods, the spring pushes the pressure plate downwards, and the rubber pad tightly fits the edge of the paper to prevent slippage.

[0022] In this invention, the drawing paper can be wound up by a winding mechanism, the angle of the table can be fixed by a fixing mechanism, and the two ends of the drawing paper can be pressed down and fixed by a pressing mechanism. Attached Figure Description
