Description

Technical Field

[0001] The present invention relates to the technical field of surveying tools, and particularly to a surveying support for improving stability. Background Art

[0002] Geographic information surveying and mapping is based on computer technology, optoelectronic technology, network communication technology, space science, and information science, with the global positioning system, remote sensing, and geographic information system as the technical core. It obtains the graphics and position information reflecting the current situation of the ground through measurement means for the feature points and boundaries existing on the ground, and is used for the planning and design of engineering construction and administrative management.

[0003] However, in surveying and mapping work, various instruments are required to be in a horizontal state during operation. Therefore, the tripod came into being. On the one hand, the tripod serves as a bearing platform for various instruments. On the other hand, by adjusting the legs of the tripod, the instrument can be in a horizontal state to meet the working requirements. However, the existing drawing mechanism and surveying mechanism are relatively independent individuals. Surveying work often requires going out frequently. In windy weather, when surveyors hold a drawing board to draw, the upper paper is easily blown up, thus affecting the normal drawing of surveyors. Moreover, in windy weather, the detection instruments are also easily affected. For this reason, we propose a surveying support for improving stability. Summary of the Invention

[0017] The present invention has at least the following beneficial effects:

[0018] In the present invention, when a user uses the auxiliary bracket for geographic information surveying and mapping, first, the three supporting legs I on the auxiliary bracket are opened. The mounting base is designed in a frustum shape and has a groove inside, so that the three supporting legs I can be effectively limited to the maximum angle after being opened, which is convenient for the user to quickly position. After the three supporting legs I are opened, the length of the supporting leg II can be adjusted according to the actual situation. After the adjustment is completed, the positioning lock is tightened, so that the supporting leg II can be effectively positioned, ensuring that the mounting base is in a horizontal position. After the mounting base is positioned, the user can fix the carried drawing board to two of the supporting legs I of the auxiliary bracket. When fixing, first rotate the clamping rod by 90 degrees. After the rotation is completed, the two clamping rods are respectively placed into the corresponding side blocks II, and both ends of the rotating rod are placed on the two side blocks I at the same time. After being placed, the position of the drawing board can be effectively positioned. Combined with the fixation of the auxiliary bracket, it is convenient for the user to rely on the auxiliary bracket to carry out surveying and drawing after the measurement. When encountering strong wind weather, if there is an oncoming wind, the wind will blow and press the drawing board at this time, so that two of the supporting legs I are stressed, thereby effectively increasing the pressing force between the two supporting legs I and the contact surface, and effectively improving the stability of the present auxiliary bracket during use. If there is a back wind, the connected drawing board rotates through the rotating rod. When the rotating rod rotates, the dial drives the connecting block II to rotate. When the connecting block II rotates, the curved rod starts to slide. After the curved rod slides, the reed resets, so that the connecting block I rotates slightly by a certain distance, so that the bolt releases the locking state of the movable rod, and the hanging ball starts to slowly shift downward. The hanging ball is also designed as a magnetic ball. When the hanging ball shifts to the rear side of the drawing board, it generates a certain magnetic attraction force on the drawing board, so that the drawing board starts to reset. After the drawing board resets, the curved rod resets. The elastic force of the first spring is greater than the elastic force of the reed, so that the rope body pulls the connecting block I to reset again, so that the bolt is tightened, and the bolt effectively positions the movable rod, so that the position of the hanging ball can be effectively fixed. And when the hanging ball moves downward, the center of gravity of the auxiliary bracket effectively moves downward, effectively avoiding the phenomenon that the existing drawing mechanism and surveying mechanism are relatively independent individuals. Since surveying work often requires going out frequently, when surveying personnel hold the drawing board to draw in strong wind weather, the upper paper is easily blown up, affecting the normal drawing of surveying personnel, and in strong wind weather, the detection instrument is also easily affected, thus ensuring the stability of the auxiliary bracket for geographic information surveying and mapping during use.

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to Figures 1-12 , the present invention provides a technical solution: a surveying and mapping support for improving stability, including: a support member 1; the support member 1 is used for installing, supporting and positioning a detection device.

[0034] A painting member 2 for measurement and painting is arranged on the support member 1.

[0035] A transmission member 3 for adjusting the center of gravity of the support member 1 by the blowing of the painting member 2 is provided between the painting member 2 and the support member 1. When the user uses the auxiliary bracket for geographic information surveying and mapping, first, the three first support legs 41 on the auxiliary bracket are opened. The mounting base 4 is designed in a frustum shape and has a groove inside, so that the three first support legs 41 can be effectively limited to the maximum angle after being opened, which is convenient for the user to quickly locate. After the three first support legs 41 are opened, the length of the second support leg 42 can be adjusted according to the actual situation. After the adjustment is completed, the positioning lock 43 is tightened, so that the second support leg 42 can be effectively positioned, ensuring that the mounting base 4 is in a horizontal position. After the mounting base 4 is positioned, the user can fix the carried drawing board 23 to two of the first support legs 41 of the auxiliary bracket. When fixing, first rotate the clamping rod 61 by 90 degrees. After the rotation is completed, the two clamping rods 61 are respectively placed into the corresponding second side blocks 48, and both ends of the rotating rod 22 are placed on the two first side blocks 47 at the same time. After being placed, the position of the drawing board 23 can be effectively positioned. Combined with the fixation of the auxiliary bracket, it is convenient for the user to rely on the auxiliary bracket for surveying and drawing after the measurement. When encountering strong wind weather, if there is an oncoming wind, the wind will blow and press the drawing board 23 at this time, so that two of the first support legs 41 are stressed, thereby effectively increasing the pressing force between the two first support legs 41 and the contact surface, and effectively improving the stability of the auxiliary bracket during use. If there is a back wind, the connected drawing board 23 will rotate through the rotating rod 22. When the rotating rod 22 rotates, the dial block 27 drives the second connecting block 310 to rotate. When the second connecting block 310 rotates, the curved rod 311 starts to slide. After the curved rod 311 slides, the reed 34 is reset, so that the first connecting block 32 rotates slightly by a certain distance, so that the bolt 31 releases the locking state of the movable rod 45, so that the hanging ball 46 starts to slowly move downward. The hanging ball 46 is also designed as a magnetic ball. When the hanging ball 46 moves to the rear side of the drawing board 23, a certain magnetic attraction force is generated on the drawing board 23, so that the drawing board 23 starts to reset. After the drawing board 23 is reset, the curved rod 311 is reset. The elastic force of the first spring 312 is greater than the elastic force of the reed 34, so that the rope body 35 pulls the first connecting block 32 to reset again, so that the bolt 31 is tightened, so that the bolt 31 effectively positions the movable rod 45, so that the position of the hanging ball 46 can be effectively fixed. And when the hanging ball 46 moves downward, the center of gravity of the auxiliary bracket effectively moves downward, effectively avoiding the situation that the existing drawing mechanism and surveying mechanism are relatively independent individuals in the past, and surveying work often requires going out frequently,When there is a strong wind, when the surveying and mapping personnel hold the drawing board 23 to draw, the upper paper is likely to be blown up, which affects the normal drawing of the surveying and mapping personnel. Also, in strong wind weather, the detection instrument is also likely to be affected, thus ensuring the stability of the auxiliary support for geographic information surveying and mapping during use.,

[0036] The support member 1 includes a mounting seat 4 for installing and positioning the measuring device. At the bottom of the mounting seat 4, a plurality of support legs one 41 arranged in a circular array are rotatably connected. A support leg two 42 is slidably connected to each of the support legs one 41. A positioning lock 43 for adjusting and positioning the support leg two 42 is fixedly installed on each of the support legs one 41. A fixed rod 44 is fixedly installed at the bottom end of the mounting seat 4. A movable rod 45 is slidably connected in the fixed rod 44. A hanging ball 46 is fixedly installed at the bottom end of the movable rod 45. Side blocks one 47 are fixedly installed on two of the support legs one 41 respectively. Below the side blocks one 47, side blocks two 48 installed on the corresponding support legs one 41 are provided. The hanging ball 46 also adopts a magnetic ball design. When the hanging ball 46 moves to the rear side of the drawing board 23, a certain magnetic attraction force is generated on the drawing board 23, so that the drawing board 23 starts to reset. After the drawing board 23 resets, the curved rod 311 resets. The elastic force of the first spring 312 is greater than the elastic force of the reed 34, so that the rope body 35 pulls the first connecting block 32 to reset again, so that the bolt 31 is tightened, and the bolt 31 effectively positions the movable rod 45, so that the position of the hanging ball 46 can be effectively fixed. And when the hanging ball 46 moves down, the center of gravity of the auxiliary support effectively moves down.,

[0037] Arc-shaped grooves are formed on the side blocks one 47 respectively. Square grooves are formed on the side blocks two 48 respectively. The side blocks two 48 are designed as cuboids. Combining with the square grooves on the side blocks two 48, the two side frames 21 can be effectively positioned after being placed. And when encountering strong wind, the positions of the two side frames 21 can be effectively positioned. The arc-shaped groove design on the side blocks one 47, combining with the rotating rod 22, enables the drawing board 23 to rotate effectively after encountering strong wind, thus realizing the rotation action of the dialing block 27.,

[0038] The drawing member 2 includes two symmetrical side frames 21 disposed between two support legs 41. A same rotating rod 22 is rotatably connected between the side frames 21. A drawing board 23 is fixedly installed on the rotating rod 22. Two paper pressing blocks 24 of the same size are installed on the side of the drawing board 23 facing away from the side frames 21. A same rain cover 25 is rotatably connected to the two side frames 21. One end of the rotating rod 22 is fixedly installed with a first collar 26. A dial block 27 is fixedly connected to the outer side of the first collar 26. The paper pressing block 24 is designed with a magnetic block, and the surface of the drawing board 23 can be made of a metal skin or filled with a metal sandwich inside. In this way, the combination of the drawing board 23 and the two paper pressing blocks 24 can achieve the positioning of the survey drawing paper, which is convenient for the user to conduct surveying and mapping. Combined with the magnetic ball design of the hanging ball 46, the drawing board 23 can be effectively reset.

[0039] The vertical cross-section of the dial block 27 is L-shaped. Positioning members 6 for positioning the placement of the side frames 21 are provided between the side frames 21 and the corresponding support legs 41. A top support member 5 for positioning the rain cover 25 is provided between the rain cover 25 and one of the side frames 21. The dial block 27 is designed with an L-shape. Combined with the fitting of the drawing board 23 and the second connecting block 310 after installation, when the auxiliary support encounters strong winds, the dial block 27 can rotate effectively, thus realizing the rotation action of the second connecting block 310.

[0040] The positioning member 6 includes positioning rods 61 rotatably connected to the opposite sides of the two side frames 21. Limiting blocks 62 installed on the side frames 21 are provided at the tops of the positioning rods 61. Through the limiting blocks 62, when the positioning rods 61 rotate by 90 degrees and then are placed with the second side block 48, it can effectively position the second side block 48, which ensures the normal fixation of the drawing board 23. When the drawing board 23 is not in use, the positioning rods 61 can be rotated and retracted, thereby reducing the unfolded area and avoiding the phenomenon of scratching with branches or rock masses in the wild.

[0041] The top support member 5 includes a first connecting rod 51 fixedly installed on one of the side frames 21. A second connecting rod 52 is slidably connected inside the first connecting rod 51. Moving grooves matching the second connecting rod 52 are provided in both the first connecting rod 51 and the side frame 21. A second spring 53 is connected between the moving groove and one end of the second connecting rod 52. Through the moving groove, the second connecting rod 52 is kept in a protruding state by the second spring 53 during normal use.

[0042] The second connecting rod 52 is designed with a U-shaped bent rod and two straight rods on both sides. When the second connecting rod 52 is in normal use, it can support and lift the rain cover 25. Since the drawing board 23 is also inclined after connection, it is not only convenient for the user to draw, but also expands the stress area when encountering the oncoming wind, making the auxiliary support for geographic information surveying and mapping more stable during use.

[0043] The transmission member 3 includes a bolt 31 screwed on the fixed rod 44 for positioning the movable rod 45. A first connecting block 32 is fixedly installed on the outer side of the bolt 31. A first fixing block 33 installed on the fixed rod 44 is arranged on the outer side of the first connecting block 32. A reed 34 is installed between the first fixing block 33 and the first connecting block 32. The top end of the first connecting block 32 is fixedly connected with a rope body 35. A guide block 36 installed on the fixed rod 44 is arranged on the outer side of the rope body 35. A guide wheel 37 for positioning and guiding the rope body 35 is arranged on the outer side of the rope body 35. An adjusting frame 38 for adjusting the height of the guide wheel 37 is installed between the guide wheel 37 and one of the first support legs 41. The other end of the rope body 35 is fixedly installed with a curved rod 311. Through the guide wheel 37 and the adjusting frame 38, when the user uses it, the rope body 35 can be adjusted to a tightened state after being opened, so that when encountering strong winds during use, the auxiliary support can effectively make normal protective measures automatically. When the support is used up, the rope body 35 can be tightened again, thus avoiding the phenomenon of the hanging ball 46 coming loose.

[0044] A second fixing block 313 installed on one of the first side blocks 47 is slidably connected to the outer side of the curved rod 311. A second collar 39 rotatably connected to one of the first side blocks 47 is arranged on the outer side of the second fixing block 313. A second connecting block 310 is fixedly installed on the outer side of the second collar 39. The second connecting block 310 is fixed to the other end of the curved rod 311. A first spring 312 installed on the curved rod 311 is arranged between the second connecting block 310 and the second fixing block 313. Through the second fixing block 313, after the curved rod 311 is displaced, it can effectively slide in a fixed direction, ensuring the normal reset of the curved rod 311 by the first spring 312 later.

[0045] Embodiment 2:

[0046] As Figure 4 shown, in the second embodiment, other structures remain unchanged. The present invention also provides a baffle 54. When encountering sudden rainfall weather, the drawing board 23 can be moved a certain distance to the right. When the drawing board 23 is displaced, since the second connecting rod 52 is blocked by the baffle 54, the second connecting rod 52 begins to contract. When the drawing board 23 is displaced to a predetermined distance, combined with the design of the second connecting rod 52 using a U-shaped bent rod and two straight rods on both sides, the concave part of the second connecting rod 52 contacts the side feet of the rainproof cover 25, so that the rainproof cover 25 can effectively rotate by a certain angle and then position itself, thus ensuring that the rainproof cover 25 protects the drawing paper on the drawing board 23 and does not affect the normal painting of the user.

[0047] Embodiment 3:

[0048] As Figure 10As shown in the figure, in the second embodiment, with other structures remaining unchanged, the present invention further provides another form of the curved rod 311. Here, the curved rod 311 is divided into the first bent rod 7 and the second bent rod 71. The first bent rod 7 is provided with an activity cavity that cooperates with the second bent rod 71. The top end of the second bent rod 71 is connected to the rope body 35, and the top end of the first bent rod 7 is fixed to the first fixing block 33. Both the first fixing block 33 and the first bent rod 7 are provided with wire grooves that cooperate with the rope body 35. The other end of the second bent rod 71 is fixed to the second connecting block 310. If a wind blows in the opposite direction, the connected drawing board 23 rotates through the rotating rod 22. When the rotating rod 22 rotates, the dial block 27 drives the second connecting block 310 to rotate. When the second connecting block 310 rotates, the second bent rod 71 starts to slide. After the second bent rod 71 slides, the reed 34 resets, causing the first connecting block 32 to rotate slightly by a certain distance. This unlocks the bolt 31 from the movable rod 45, causing the hanging ball 46 to start moving downward slowly. The hanging ball 46 also adopts a magnetic ball design. When the hanging ball 46 moves to the rear side of the drawing board 23, it generates a certain magnetic attraction force on the drawing board 23, causing the drawing board 23 to reset. After the drawing board 23 resets, the second bent rod 71 resets. The elastic force of the first spring 312 is greater than the elastic force of the reed 34, causing the rope body 35 to pull the first connecting block 32 to reset, tightening the bolt 31, and effectively positioning the bolt 31 on the movable rod 45, so that the position of the hanging ball 46 can be effectively fixed. When the hanging ball 46 moves downward, the center of gravity of the auxiliary support effectively moves downward, effectively avoiding the phenomenon that the existing drawing mechanism and surveying mechanism are relatively independent individuals in the past. In surveying work, it is often necessary to go out frequently. In windy weather, when surveyors hold the drawing board 23 to draw, the upper paper is easily blown up, affecting the normal drawing of surveyors. Also, in windy weather, the detection instrument is easily affected, thus ensuring the stability of the auxiliary support for geographic information surveying during use.

[0049] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article or device.

[0050] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
