DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0021] Traditionally, when surveying and mapping, workers use a bracket without a leveling device to survey and map. This means that when surveying and mapping on uneven ground, the results of the surveying and mapping will be affected by the inclination of the ground, resulting in large errors in the results drawn by the workers.

[0022] In view of this, the utility model provides a surveying and mapping bracket that is easy to level. The surveying and mapping bracket that is easy to level solves the problem of large errors that are prone to occur when drawing on uneven ground using traditional brackets without leveling through a leveling device, a supporting device and a clamping device. The equipment can reduce the impact of uneven ground on drawing when workers are drawing through the leveling device, and can make workers draw more conveniently through the supporting device and the clamping device.

[0023] Embodiment 1: Figure 1 , 2 , 3 and 4 show that a surveying and mapping bracket that is convenient for leveling comprises a bottom plate 1, a first horizontal plate 2 is rotatably connected to the top of the bottom plate 1, a top plate 3 is arranged above the first horizontal plate 2, and the surveying and mapping bracket that is convenient for leveling further comprises: a lifting device 4, installed below the top plate 3; a leveling device 5, arranged below the first horizontal plate 2; a supporting device 6, installed at the bottom of the bottom plate 1; a clamping device 7, arranged at the top of the top plate 3; the first horizontal plate 2 can be rotated along the outer wall of the bottom plate 1 by a pin shaft, and the top plate 3 can be leveled in cooperation with the leveling device 5, and the supporting angle of the supporting device 6 can be adjusted according to the surveying and mapping height and ground conditions; wherein the lifting device 4 can adjust the height of the top plate 3, the leveling device 5 can level the top plate 3, the supporting device 6 can support the surveying and mapping bracket that is convenient for leveling, and the clamping device 7 can clamp the drawings;

[0024] In the specific implementation process, it is worth pointing out that the first horizontal plate 2 can be rotated along the outer wall of the bottom plate 1 through the pin shaft, and the top plate 3 can be leveled in cooperation with the leveling device 5, and the supporting angle of the supporting device 6 can be adjusted according to the surveying height and the ground conditions;

[0025] Specifically, when using the surveying and mapping bracket that is easy to level, the worker first opens the supporting device 6. When the supporting angle of the supporting device 6 is adjusted to a suitable position, the worker places the surveying and mapping bracket that is easy to level on the ground, and then fixes the drawing through the clamping device 7 to avoid the drawing from being offset during drawing. Then the worker adjusts the leveling device 5 according to the inclination of the ground until the angle of the top plate 3 is horizontal. The worker can then start surveying and mapping. In addition, the worker can also use the lifting device 4 to adjust the surveying and mapping bracket that is easy to level to a suitable position according to his height, so that the worker can perform surveying and mapping operations more comfortably.

[0026] Embodiment 2: By Figure 1 , 2 As can be seen from Figure 3, the lifting device 4 includes: a shell 401, installed on the top of the first horizontal plate 2; a rotating rod 402, rotatably connected to the inner wall of the shell 401 through a bearing; a first bevel gear 403, installed on one side of the rotating rod 402; a second bevel gear 404, meshingly connected to the outer wall of the first bevel gear 403; a first threaded rod 405, installed on the inner wall of the second bevel gear 404, and rotatably connected to the inner wall of the bottom plate 1 through a bearing, and the first threaded rod 405 is rotatably connected to the inner wall of the shell 401 through a bearing; a first vertical pipe 406, threadedly connected to the outer wall of the first threaded rod 405, and fixedly connected to the bottom of the top plate 3; four second vertical pipes 407 are provided, and are respectively installed on the first horizontal plate 2; four first vertical rods 408 are provided, which are respectively provided at the four bottom corners of the top plate 3 and are plugged into the inner walls of the four second vertical tubes 407; when the top plate 3 is lifted, the first vertical rod 408 is forced to move along the inner wall of the second vertical tube 407, and the movement path of the top plate 3 is restricted, so that the top plate 3 can only move upward or downward, and the second bevel gear 404 can convert the lateral force received by the first bevel gear 403 into a vertical force, and the height adjustment operation is completed by changing the direction of the force, wherein the rotating rod 402 can drive the first bevel gear 403 to drive the second bevel gear 404 to rotate, thereby causing the first threaded rod 405 to drive the first vertical tube 406 to move upward to perform the height adjustment operation;

[0027] In the specific implementation process, it is worth pointing out that when the top plate 3 is lifted, the first vertical rod 408 is forced to move along the inner wall of the second vertical tube 407, and the movement path of the top plate 3 is restricted, so that the top plate 3 can only move upward or downward, and the second bevel gear 404 can convert the lateral force received by the first bevel gear 403 into a vertical force, and the height adjustment operation is completed by changing the direction of the force;

[0028] Specifically, on the basis of the above-mentioned embodiment 1, when the staff wants to adjust the top plate 3, they first rotate the rotating rod 402. The rotating rod 402 is rotated by force and drives the first bevel gear 403 to rotate at the same time. When the first bevel gear 403 rotates, it will drive the second bevel gear 404. At the same time, the first bevel gear 403 will convert the lateral force it receives into a vertical force through the second bevel gear 404. The second bevel gear 404 drives the first threaded rod 405 to start rotating. At this time, the first vertical tube 406 is forced to move along the outer wall of the first threaded rod 405, so that the first vertical tube 406 lifts the top plate 3 to complete the height adjustment operation.

[0029] Embodiment 3: By Figure 1 , 2 As can be seen from 4, the leveling device 5 includes: two limit plates 501, which are respectively installed on both sides of the top of the bottom plate 1, and the top of the limit plate 501 close to the rotating rod 402 is in contact with the bottom of the first horizontal plate 2; the second threaded rod 502 is rotatably connected to the inner walls of the two limit plates 501 through a bearing; the limit block 503 is threadedly connected to the outer wall of the second threaded rod 502; the slide rail 505 is installed at the bottom of the first horizontal plate 2; the first slider 504 is rotatably connected to the outer wall of the limit block 503 through a pin shaft, and is slidably engaged with the outer wall of the slide rail 505; wherein, rotating the second threaded rod 502 can drive the limit block 503 to push the first slider 504 to slide along the outer wall of the slide rail 505, thereby changing the angle between the first horizontal plate 2 and the top plate 3 to perform leveling operations;

[0030] In the specific implementation process, it is worth pointing out that the slideway of the slide rail 505 is an inclined surface, and the slideway close to the rotating rod 402 is lower than the slideway on the other side. When the first slider 504 is forced to move along the outer wall of the slide rail 505 in the direction away from the rotating rod 402, the first horizontal plate 2 and the top plate 3 are forced to be lifted up. When the first slider 504 moves along the outer wall of the slide rail 505 toward the rotating rod 402, the first horizontal plate 2 and the top plate 3 begin to fall back until the first horizontal plate 2 fits with the limiting plate 501.

[0031] Specifically, on the basis of the above-mentioned embodiment 1, when the surveying ground is tilted and the staff needs to level the top plate 3, the second threaded rod 502 is first rotated. The second threaded rod 502 is forced to rotate along the inner wall of the limit plate 501 through the bearing, and drives the limit block 503 to slide along the outer wall of the second threaded rod 502. When the limit block 503 moves, it will drive the first slider 504 to slide along the outer wall of the slide rail 505. At this time, the first cross plate 2 and the top plate 3 are forced to be lifted up. Because one end of the first cross plate 2 is rotatably connected to the outer wall of the bottom plate 1 through a pin shaft, the first cross plate 2 and the top plate 3 will be tilted as a whole. Until the top plate 3 is horizontal, the worker stops rotating the second threaded rod 502 to complete the leveling operation.

[0032] Embodiment 4: By Figure 1and 2 It can be seen that the supporting device 6 includes: a second horizontal plate 601, which is installed at the bottom of the base plate 1; a second vertical rod 602, which is arranged at the bottom of the second horizontal plate 601; a second slider 603, which is arranged on the outer wall of the second vertical rod 602; three support plates 604 are arranged, and all of them are rotatably connected to the outer wall of the second slider 603 through a pin shaft; three supporting legs 605 are arranged, which are rotatably connected to the outer wall of the second horizontal plate 601 through a pin shaft, and are rotatably connected to the outer walls of the three supporting plates 604 through a pin shaft; wherein, when the second slider 603 slides along the outer wall of the second vertical rod 602, the supporting plate 604 can be driven to drive the supporting legs 605 to rotate along the outer wall of the second horizontal plate 601;

[0033] In the specific implementation process, it is worth pointing out that the second horizontal plate 601 and the support leg 605 are connected by a pin shaft, so that the unfolding angle can be adjusted, which is convenient for workers to survey and map. When the worker finishes mapping, the support leg 605 can be retracted by the pin shaft, which is convenient for subsequent carrying operations.

[0034] Specifically, on the basis of the above-mentioned embodiment 1, before conducting surveying and mapping, the staff will unfold the support device 6 to support the surveying and mapping bracket for easy leveling. First, the worker will punch the support leg 605 outward, and the support leg 605 will rotate along the outer wall of the second horizontal plate 601 through the pin shaft. At the same time, the support leg 605 will drive the support plate 604 to move. The support plate 604 will begin to drive the second slider 603 to slide along the outer wall of the second vertical rod 602 until the support leg 605 is unfolded to a suitable position. At this time, the support plate 604 can support the support leg 605 and the second slider 603.

[0035] Embodiment 5: By Figure 1 and 2 It can be seen that the clamping device 7 includes: a fixing clamp 701, which is installed on the top of the top plate 3; a torsion spring 702, which is arranged inside the fixing clamp 701; the fixing clamp 701 can clamp the drawing through the torsion spring 702 to prevent the drawing from being offset when the worker is drawing, which causes a large error in the drawing result; wherein, the fixing clamp 701 can clamp the drawing through the torsion spring 702;

[0036] In the specific implementation process, it is worth pointing out that the fixing clamp 701 can clamp the drawing through the torsion spring 702 to prevent the drawing from being offset by the force when the worker is drawing, which will cause a large error in the drawing result.

[0037] Specifically, based on the above-mentioned embodiment 1, when the staff performs the clamping operation on the drawing, they first rotate the fixing clamp 701 upwards. At this time, the torsion spring 702 is forced to drive the fixing clamp 701 to move upwards. Then the drawing is placed on the top plate 3, and one end of the drawing is moved to the bottom of the fixing clamp 701. Then the worker releases the fixing clamp 701, and the torsion spring 702 is no longer forced and drives the fixing clamp 701 to clamp the drawing, thereby completing the clamping operation of the drawing.

[0038] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions.
