AI Technical Summary
[0003]然而，传统绘图装置支撑板的高度大多为固定结构，无法根据不同身高的绘图人员或不同作业场景（如站立绘图、坐姿绘图）的需求灵活调整高度，长期使用易导致绘图人员出现腰背酸痛等疲劳问题，影响绘图效率与精度，且传统装置多为一体化刚性结构，体积庞大且不方便折叠，在野外测绘、多地点作业等场景下，携带与运输过程中占用空间大，操作费力，难以满足测绘工程移动作业的需求
[0014]The beneficial effects of this utility model are as follows: During use, the drawing can be placed on the support plate, which provides a stable and flat support surface to ensure drawing accuracy. When the height of the support plate needs to be adjusted, the two second sleeves can slide inside the two first sleeves respectively. After the relative position between the second and first sleeves is adjusted, the fixing knob on the first sleeve can be rotated to make its end abut against the second sleeve, thus preventing the first and second sleeves from moving. Then, the two third sleeves can slide inside the two second sleeves respectively. After the relative position between the second and third sleeves is adjusted, the fixing knob on the second sleeve can be rotated to make its end abut against the third sleeve, thus preventing the third sleeve from moving. At this point, the height of the support plate can be adjusted. The height can be adjusted to accommodate drafters of different heights and work scenarios, improving ease of use and comfort. When carrying and transporting the drafting device, the first limiting structure can quickly release the restriction on the connecting block, and then the support plate can be rotated to a horizontal position with the third sleeve. Then, the second sleeve slides towards the inside of the first sleeve, and the third sleeve slides towards the inside of the second sleeve. The second limiting structure then quickly releases the restriction on the connecting plate. Finally, the two first sleeves are rotated towards the base. When the two first sleeves are parallel to the base, the second limiting structure will restrict the connecting plate again. At this time, the first sleeves cannot rotate, thus realizing the quick folding and storage of the drafting device, effectively reducing the space occupied by the drafting device, facilitating the carrying and transportation of the drafting device, and thus adapting to the mobile operation needs of surveying and mapping engineering.

Abstract
Description
Technical Field
[0001] This utility model relates to a drawing device for surveying engineering, specifically an adjustable drawing device for surveying engineering, belonging to the technical field of auxiliary equipment for surveying engineering. Background Technology
[0002] Surveying and mapping engineering is an engineering discipline that measures, collects, processes, analyzes, describes, and applies the spatial location, shape, size, and attributes of natural and artificial elements on the Earth's surface. It is widely used in fields such as land planning, urban construction, transportation and water conservancy projects, and mineral resource exploration. In the process of surveying and mapping engineering, drawing is one of the core links, which requires converting measurement data into intuitive drawings (such as topographic maps, engineering layout drawings, etc.). During the drawing process, a support plate must be used to provide a stable and flat support surface for the drawings to ensure the accuracy of the drawings.
[0003] However, the height of the support plate of traditional drawing devices is mostly fixed, which cannot be flexibly adjusted according to the needs of drawing personnel of different heights or different working scenarios (such as standing drawing or sitting drawing). Long-term use can easily lead to fatigue problems such as back pain for drawing personnel, affecting drawing efficiency and accuracy. In addition, traditional devices are mostly integrated rigid structures, which are bulky and inconvenient to fold. In scenarios such as field surveying and multi-location operations, they take up a lot of space during carrying and transportation, and are laborious to operate, making it difficult to meet the needs of mobile surveying and mapping operations. Utility Model Content
[0004] The purpose of this invention is to provide an adjustable drawing device for surveying engineering to solve the above problems. The height of the support plate can be flexibly adjusted to suit drawing personnel of different heights and working scenarios, improving ease of use and comfort. At the same time, when drawing is not required, the device can be quickly folded and stored, making it easy to carry and transport, and adapting to the needs of mobile surveying engineering operations.

[0009] Preferably, the second limiting structure includes a slide rod and a connecting plate. Two slide rods are slidably connected to the base, and the same connecting plate is fixedly connected to the two slide rods. Two locking blocks are fixedly connected to the connecting plate, and a limiting block is fixedly connected to the connecting plate. The locking blocks engage with the adjacent limiting blocks.
[0010] Preferably, a second spring is sleeved on the outside of the slide rod, with one end of the second spring abutting against the slide rod and the other end of the second spring abutting against the base.

[0014] The beneficial effects of this utility model are as follows: During use, the drawing can be placed on the support plate, which provides a stable and flat support surface to ensure drawing accuracy. When the height of the support plate needs to be adjusted, the two second sleeves can slide inside the two first sleeves respectively. After the relative position between the second and first sleeves is adjusted, the fixing knob on the first sleeve can be rotated to make its end abut against the second sleeve, thus preventing the first and second sleeves from moving. Then, the two third sleeves can slide inside the two second sleeves respectively. After the relative position between the second and third sleeves is adjusted, the fixing knob on the second sleeve can be rotated to make its end abut against the third sleeve, thus preventing the third sleeve from moving.

Then, the second sleeve slides towards the inside of the first sleeve, and the third sleeve slides towards the inside of the second sleeve. The second limiting structure then quickly releases the restriction on the connecting plate. Finally, the two first sleeves are rotated towards the base. When the two first sleeves are parallel to the base, the second limiting structure will restrict the connecting plate again. At this time, the first sleeves cannot rotate, thus realizing the quick folding and storage of the drafting device, effectively reducing the space occupied by the drafting device, facilitating the carrying and transportation of the drafting device, and thus adapting to the mobile operation needs of surveying and mapping engineering.

Detailed Implementation
[0017] 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.
[0018] Please see Figures 1-8 As shown, an adjustable surveying and mapping engineering drawing device includes a base 1, a support structure 2 on the base 1, the support structure 2 including a first connecting shaft 201 and a connecting plate 202, two first connecting shafts 201 fixedly connected to the base 1, a connecting plate 202 rotatably connected to the first connecting shafts 201, a first sleeve 203 fixedly connected to the connecting plate 202, a second sleeve 204 slidably connected inside the first sleeve 203, a third sleeve 205 slidably connected inside the second sleeve 204, a fixing knob 206 threadedly connected to the first sleeve 203, a fixing knob 206 threadedly connected to the second sleeve 204, a second connecting shaft 207 fixedly connected to the third sleeve 205, a connecting block 208 rotatably connected to the second connecting shaft 207, a common support plate 209 fixedly connected to one end of the two connecting blocks 208, a first limiting structure 3 on the third sleeve 205, and a second limiting structure 4 on the base 1.
[0019] As a technical optimization of this utility model, the first limiting structure 3 includes a plug rod 301 and a pull rod 302. The plug rod 301 is slidably connected to the third sleeve 205. The connecting block 208 is provided with a slot 306. The support plate 209 can be kept horizontal by the engagement between the plug rod 301 and the slot 306, which facilitates the formation of a stable support for the drawing. The pull rod 302 is fixedly connected to the plug rod 301. The plug rod 301 can be easily pulled by holding the pull rod 302.
[0020] As a technical optimization of this utility model, a connecting piece 304 is fixedly connected to the insertion rod 301, and a first spring 305 is sleeved on the outside of the insertion rod 301. One end of the first spring 305 abuts against the connecting piece 304, and the other end of the first spring 305 abuts against the third sleeve 205. Under the action of the first spring 305, the insertion rod 301 can always be engaged with the slot 306.
[0021] As a technical optimization of this utility model, the cross-section of one end of the insertion rod 301 is trapezoidal, so it can play a role in guiding the movement when the insertion rod 301 is engaged with the slot 306. A support block 303 is rotatably connected to the pull rod 302. The support block 303 can support the pull rod 302 after it is released, thereby preventing the insertion rod 301 from engaging with the slot 306 again under the action of the first spring 305.
[0022] As a technical optimization of this utility model, the second limiting structure 4 includes a slide rod 401 and a connecting plate 402. Two slide rods 401 are slidably connected to the base 1, and the same connecting plate 402 is fixedly connected to the two slide rods 401. Two locking blocks 403 are fixedly connected to the connecting plate 402, and a limiting block 404 is fixedly connected to the connecting plate 202. The locking block 403 engages with the adjacent limiting block 404, thus fixing the connecting plate 202, so that the first sleeve 203 can always maintain a specific orientation.
[0023] As a technical optimization of this utility model, a second spring 405 is sleeved on the outside of the slide rod 401. One end of the second spring 405 abuts against the slide rod 401, and the other end of the second spring 405 abuts against the base 1. Under the action of the second spring 405, the locking block 403 can always be engaged with the limiting block 404.
[0024] As a technical optimization of this utility model, the overall cross-section of the limiting block 404 is square. Therefore, when the connecting plate 202 rotates 90 degrees, the locking block 403 can engage with the limiting block 404 again. The cross-section of one end of the sliding rod 401 is convex. A handle 406 is fixedly connected to the connecting plate 402, so the connecting plate 402 can be easily pulled by holding the handle 406.
[0025] As a technical optimization of this utility model, a storage box 6 is slidably connected inside the base 1, through which paper can be stored. A handle 7 is rotatably connected to the base 1, through which the drawing device can be easily moved by holding the handle 7.
[0026] As a technical optimization of this utility model, a pull block 5 is fixedly connected to one end of the storage box 6. The overall cross-section of the pull block 5 is L-shaped, so the storage box 6 can be easily pulled out from the inside of the base 1 by holding the pull block 5, which facilitates the taking and putting away of paper.
[0027] In use, this invention allows drawings to be placed on a support plate 209, which provides a stable and flat support surface to ensure drawing accuracy. When the height of the support plate 209 needs adjustment, the two second sleeves 204 slide inside the two first sleeves 203. After the relative positions of the second sleeves 204 and the first sleeves 203 are adjusted, the fixing knob 206 on the first sleeve 203 is rotated to make its end abut against the second sleeve 204, thus preventing movement between the first sleeve 203 and the second sleeve 204. Then, the two third sleeves 205 are respectively positioned inside the two... The second sleeve 204 slides internally. After the relative position between the second sleeve 204 and the third sleeve 205 is adjusted, the fixed knob 206 on the second sleeve 204 can be rotated to make its end abut against the third sleeve 205, thus preventing the third sleeve 205 from moving with the second sleeve 204. At this time, the height of the support plate 209 can be adjusted, making it easier to adapt to drafters of different heights and working scenarios, improving ease of use and comfort. When carrying and transporting the drafting device, the insertion rod 301 can be pulled by holding the pull rod 302, and the first spring 305 will retract. When the end of the insertion rod 301 is not locked with the slot 306, the support plate can be adjusted. When block 303 is rotated to a horizontal position with insert rod 301, and then pull rod 302 is released, support block 303 can support pull rod 302, thus preventing insert rod 301 from engaging with slot 306 again under the action of first spring 305 after pull rod 302 is released. When both insert rods 301 are no longer engaged with slot 306, support plate 209 can be rotated to a horizontal position with third sleeve 205, and then second sleeve 204 can be slid towards the inside of first sleeve 203, and then third sleeve 205 can be slid towards the inside of second sleeve 204. Then, by holding handle 7, connecting plate 402 is pulled. The movement of connecting plate 402 will drive two sliding rods 40 1. Slide on base 1. Two second springs 405 retract simultaneously. At the same time, the movement of connecting plate 402 will cause the locking block 403 to move away from the limiting block 404. When the locking block 403 and the limiting block 404 are not engaged, the two first sleeves 203 can rotate toward base 1. When the two first sleeves 203 are parallel to base 1, the locking block 403 will engage with the limiting block 404 again under the action of the second spring 405. At this time, the first sleeves 203 cannot rotate, thus realizing the quick folding and storage of the drawing device, effectively reducing the space occupied by the drawing device, facilitating the carrying and transportation of the drawing device, and thus adapting to the needs of mobile surveying and mapping operations.
