Description

Technical Field

[0001] This utility model relates to the field of urban and rural planning, and in particular to a drawing tool for urban and rural planning design. Background Technology

[0002] "Urban planning" is a comprehensive plan that regulates urban development and construction, studies the future development of the city, the rational layout of the city, and the comprehensive arrangement of various urban construction projects. It is a blueprint for urban development within a certain period, an important component of urban management, the basis for urban construction and management, and a prerequisite for the three stages of urban planning, urban construction, and urban operation.

[0003] A search revealed Chinese patent "A Multifunctional Drawing Tool for Urban and Rural Planning" (publication number CN212796351U), which discloses a multifunctional drawing tool for urban and rural planning, relating to the field of drawing tools. This utility model includes a flat pad with graduations around its top perimeter. Two symmetrical slots are formed at the top of the pad, each located outside a corresponding graduation. A pressure plate for holding down paper is slidably connected between the two slots. By symmetrically creating two slots on the pad and slidably connecting them to the pressure plate, the design eliminates the need for manual pressure on the paper during drawing. Furthermore, the pressure plate can slide within the slots, allowing it to be moved to an appropriate position without interfering with the drawing process. In summary, this design makes drawing more convenient for designers.

[0004] Although the above-mentioned drawing tools solve the problem of inconvenience caused by the need for personnel to press down the paper by hand when drawing, the paper is prone to displacement due to friction when the pressure plate is slid. In addition, there are scales around the plate. When the personnel slide the pressure plate to the middle to draw, the pointer on the pressure plate is far from the scale. The drawing personnel may see the deviation with their eyes, thus affecting the overall drawing quality and accuracy.

[0005] Therefore, a drafting tool for urban and rural planning and design is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a drawing tool for urban and rural planning design in order to solve the above-mentioned problems. It improves the problem that the drawing device is prone to paper shifting and cannot match the drawing position with the scale, which poses a risk of drawing deviation.

[0007] This utility model achieves the above-mentioned objective through the following technical solution: a drawing tool for urban and rural planning design, comprising: a base plate and a drawing board disposed on the base plate, wherein both sides of the surface of the drawing board are provided with sliding grooves, and a scale ring is provided on the top of the drawing board;

[0008] A drawing component, wherein the drawing component is disposed above the drawing board;

[0009] The drawing component includes a sliding plate disposed above the drawing board, a pressure roller disposed below the sliding plate, a sliding hole being formed on the surface of the sliding plate, and an auxiliary device corresponding to the scale ring disposed below the sliding hole.

[0010] Preferably, a movable block is slidably connected in the sliding hole. The movable block is designed in the shape of an "I". The lower part of the movable block is fixedly connected to the auxiliary device through a bearing seat. By setting the movable block, it is convenient for the staff to adjust the horizontal position of the auxiliary device and assist the staff in drawing vertical lines at any position on the drawing.

[0011] Preferably, a limiting shell is fixedly connected to the lower part of the sliding plate, and a cylindrical groove is provided on the lower part of the limiting shell. The inner wall of the cylindrical groove of the limiting shell is movably connected to the pressure roller through a rotating shaft. The limiting shell can limit the pressure roller.

[0012] Preferably, both sides below the sliding plate are fixedly connected to slide blocks, and the surface of the slide blocks is slidably connected to the slide groove. Through the slide blocks, the sliding plate can be longitudinally limited, assisting the personnel in drawing horizontal lines at any position on the drawing.

[0013] Preferably, the sliding plate is configured to slide longitudinally, and the moving block is configured to move laterally.

[0014] Preferably, pointers are fixedly connected to both sides of the inner side of the sliding hole. The pointers correspond to the scales on both sides of the scale ring. The pointers can help the operator adjust the position of the sliding plate according to the scales on both sides of the scale ring.

[0015] Preferably, the auxiliary device is a laser emitter, the auxiliary device is arranged vertically, and the beam of the auxiliary device corresponds to the upper and lower scales of the scale ring.

[0016] The beneficial effects of this utility model are:

[0017] By setting a pressure roller under the sliding plate in the drawing component, the pressure roller is made of silicone. The elasticity of silicone can be used to press and position the drawing paper when the person is drawing. At the same time, when the sliding plate moves, the pressure roller rolls on the paper, which can effectively avoid the problem of paper slipping or shifting due to friction.

[0018] By setting up an auxiliary device and pointer, when personnel are adjusting the sliding plate for drawing, the auxiliary device can turn and emit a beam according to the personnel's needs, so as to facilitate the personnel to accurately align the drawing position with the upper and lower scales of the scale ring. At the same time, the pointer on the side can be aligned with the scales on both sides of the scale ring, which can accurately assist personnel in drawing the drawing and improve the drawing quality and accuracy.

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.

[0026] In practical implementation: such as Figure 1-5 As shown, a drawing tool for urban and rural planning design includes: a base plate 1 and a drawing board 2 disposed on the base plate 1, with grooves 3 on both sides of the surface of the drawing board 2 and a scale ring 5 disposed on the top of the drawing board 2; and a drawing component 4 disposed on the top of the drawing board 2.

[0027] like Figure 1 , Figure 2 and Figure 3As shown, the drawing component 4 includes a sliding plate 401 disposed above the drawing plate 2, a pressure roller 404 disposed below the sliding plate 401, a limiting shell 403 fixedly connected below the sliding plate 401, a cylindrical groove being provided below the limiting shell 403, and the inner wall of the cylindrical groove of the limiting shell 403 being movably connected to the pressure roller 404 via a rotating shaft.

[0028] When staff need to draw urban and rural planning drawings, they first place the drawing on the drawing board 2 and under the pressure roller 404. At this time, the silicone pressure roller 404 will press the paper tightly through its own elasticity. When drawing, the staff can adjust the position of the sliding plate 401 to make lines. When the sliding plate 401 moves, the pressure roller 404 will roll on the paper surface, which can keep the paper stable and also flatten the paper.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a sliding hole 405 is provided on the surface of the sliding plate 401, and an auxiliary device 408 corresponding to the scale ring 5 is provided below the sliding hole 405; a moving block 407 is slidably connected in the sliding hole 405, the moving block 407 is designed in the shape of "I", and the lower part of the moving block 407 is fixedly connected to the auxiliary device 408 through a bearing seat; a sliding seat 402 is fixedly connected to both sides below the sliding plate 401, and the surface of the sliding seat 402 is slidably connected to the sliding groove 3; the sliding plate 401 is set to slide vertically, and the moving block 407 is set to move horizontally; a pointer 406 is fixedly connected to both sides of the inner side of the sliding hole 405, and the pointer 406 corresponds to the scale on both sides of the scale ring 5; the auxiliary device 408 is a laser emitter, the auxiliary device 408 is set vertically, and the beam of the auxiliary device 408 corresponds to the upper and lower scales of the scale ring 5;

[0030] When drawing lines, the sliding plate 401 can be slid in the slide groove 3 via the slide block 402 to draw horizontal lines at any position on the drawing. When the sliding plate 401 moves, the position of the sliding plate 401 can be adjusted by referring to the corresponding values ​​of the pointer 406 and the scale on both sides of the scale ring 5. When drawing vertical lines, the auxiliary device 408 can be turned on. At this time, the auxiliary device 408 will emit a beam of light and illuminate the scale ring 5. The personnel only need to adjust the auxiliary device 408 left and right by the moving block 407 to reach the designated position and stop. The drawing can be carried out by the beam emitted by the auxiliary device 408 and the scale at the end of the beam. The above method can effectively improve the quality and accuracy of drawing and provide convenience for personnel.

[0031] It should be noted that: Auxiliary device 408 is a laser emitter. Laser emitters are a mature technology, and their principle is the same as that of indoor level instruments, so it will not be elaborated here.

[0032] Working principle: When staff need to draw urban and rural planning drawings, the drawing is first placed on the drawing board 2 and under the pressure roller 404. At this time, the silicone pressure roller 404 will press the paper firmly through its own elasticity. When drawing, the staff can adjust the position of the sliding plate 401 to make lines. When the sliding plate 401 moves, the pressure roller 404 will roll on the paper surface, which can keep the paper stable and also flatten it. When making lines, the staff can slide the sliding plate 401 in the slide groove 3 through the slide block 402 to make horizontal lines at any position on the drawing. When making vertical lines, the auxiliary device 408 can be opened. At this time, the auxiliary device 408 will emit a beam of light and illuminate the scale ring 5. The staff only needs to adjust the auxiliary device 408 left and right by moving the moving block 407 to reach the designated position and stop. The drawing can be made by using the beam emitted by the auxiliary device 408 and the scale at the end of the beam. The above method can effectively improve the quality and accuracy of drawing and provide convenience for staff.

[0033] Furthermore, it should be understood that 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, and 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.
