Although it can reduce the floor space to a certain extent, the reduced floor space is small and it is not convenient to carry. In the prior art, the height of the surveying and mapping device body is usually adjusted by controlling the inclination angle of the bracket. Therefore, it is inconvenient to fine-tune the height of the surveying and mapping device body when it is needed to use it.

[0005] Therefore, those skilled in the art provide an engineering cost surveying and mapping device that is convenient for recording and use to solve the problems raised in the above background technology. Utility Model Content

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] An engineering cost surveying and mapping device convenient for recording and use comprises a fixed platform and a fixed plate, first brackets are hingedly arranged at the centers of both sides and front and rear end surfaces of the fixed platform, second brackets are hingedly arranged at the lower ends of the inner walls of four first brackets, positioning mechanisms are arranged at the lower ends of both sides of the outer walls of the four first brackets, multiple positioning mechanisms comprise connecting shafts, springs are fixedly arranged at the centers of one side of the inner walls of multiple connecting shafts, and connecting rods are slidably and clamped inside the multiple connecting shafts;

[0010] Furthermore, the four telescopic rods are respectively fixedly arranged on the upper end surface of the fixing platform near the four corners and are all fixedly connected to the fixing plate.

[0018] 1. The utility model provides an engineering cost surveying and mapping device that is convenient for recording and use. By pulling two knobs located on both sides of the outer wall of the same first bracket to both sides, multiple positioning rods are respectively disengaged from multiple positioning holes, and the two springs are in a stretched state. At this time, the second bracket can be rotated to the inside of the first bracket and the two knobs and the two connecting shafts are driven to rotate synchronously. Then, the two knobs are loosened so that the two knobs drive the multiple positioning rods to respectively penetrate the multiple positioning holes located on both sides of the outer wall of the first bracket and the multiple positioning holes on one side of the outer wall of the two connecting shafts under the action of the two springs, so as to achieve the fixing effect of the rotation angle of the second bracket, so as to achieve the folding and storage of the second bracket, thereby greatly reducing the footprint of the device, and then being able to play a portable role.

[0019] 2. The utility model proposes an engineering cost surveying and mapping equipment which is convenient for recording and use. The rotating disk drives the threaded sleeve to rotate. At the same time, since the fixed plate and the fixed platform are fixedly connected by four telescopic rods, the fixed plate can only move up and down. Therefore, the threaded sleeve can be rotated to make the threaded rod move up or down, and the telescopic rod can cooperate with the telescopic rod to achieve the effect of fine-tuning the height of the surveying and mapping device body on the upper end surface of the fixed plate, which can make it easier to fine-tune the height of the surveying and mapping device body.

[0029] A knob 805 is fixedly provided on one side of the multiple connecting rods 803, and a plurality of positioning rods 804 are fixedly provided on the outer side of the multiple knobs 805.

A threaded sleeve 202 is fixedly provided at the center of the lower end surface of the inner wall of the rotating disk 204, and a threaded rod 201 is provided on the internal thread of the threaded sleeve 202.

[0030] Specifically, the supporting effect of the fixed platform 7 is achieved by the first bracket 4 and the second bracket 5, and the fixing effect of the flipping angle of the second bracket 5 is achieved by the positioning mechanism 8, so that the second bracket 5 can be folded and stored and its rotation angle can be fixed without affecting the supporting effect of the first bracket 4 and the second bracket 5, and the adjustment mechanism 2 can achieve the effect of fine-tuning the height of the fixed plate 9, and then can achieve the effect of fine-tuning the height of the surveying and mapping device body 1.

[0031] Reference Figure 1 , Figure 2 The four telescopic rods 203 are respectively fixedly arranged on the upper end surface of the fixing platform 7 near the four corners and are all fixedly connected to the fixing plate 9.

[0032] Specifically, the telescopic rod 203 can fix the rotation angle of the fixing plate 9 while cooperating with the lifting and lowering of the fixing plate 9 .

[0033] Reference Figure 1 , Figure 3 One end of the multiple springs 802 is fixedly connected to the multiple connecting rods 803 respectively, and the multiple connecting shafts 801 are rotatably set at the lower ends of the inner walls of the four first brackets 4 and are fixedly connected to the centers of the upper ends of the outer walls of the four second brackets 5 respectively.

[0034] Specifically, the spring 802 can be stretched by pulling the knob 805 to drive the connecting rod 803 to move, and the connecting shaft 801 and the knob 805 can be rotated by rotating the second bracket 5 .

[0035] Reference Figure 1 , Figure 3A plurality of positioning holes 10 are provided at the lower ends of both sides of the outer walls of the four second brackets 5 and at the outer sides of one side of the outer walls of the plurality of connecting shafts 801, and a plurality of positioning rods 804 slide through the positioning holes 10 on the outer wall of the second bracket 5 and one side of the outer wall of the plurality of connecting shafts 801, respectively.

[0036] Specifically, the rotation angle of the second bracket 5 can be fixed by designing that the positioning rod 804 passes through the positioning hole 10 .

[0037] Reference Figure 1 The surveying and mapping device body 1 is fixedly arranged on the upper end surface of the fixing plate 9 , and the four second brackets 5 are respectively embedded in the four first brackets 4 .

[0038] Specifically, the design of folding the second bracket 5 and embedding it into the first bracket 4 can reduce the footprint of the first bracket 4 and the second bracket 5, thereby facilitating storage and carrying.

[0039] Reference Figure 1 , Figure 4 The lower ends of the four second brackets 5 are hingedly provided with fixed legs 6, and the lower ends of the four fixed legs 6 are all in a pointed cone shape.

[0040] Specifically, the fixing stand 6 with a pointed cone at the lower end can be inserted into the soft ground to fix the entire device.

[0041] Reference Figure 1 , Figure 2 The fixing platform 7 is fixedly provided with hinge blocks 3 at both end surfaces and both sides thereof, and the four first brackets 4 are hingedly provided inside the four hinge blocks 3 respectively.

[0042] Specifically, the design of the hinge block 3 enables the first bracket 4 to rotate, and thus a suitable supporting angle can be adjusted by rotating the first bracket 4 .

[0043] Reference Figure 1 , Figure 2 The rotating disk 204 is rotatably arranged at the center of the upper end surface of the fixed platform 7, and the upper end surface of the threaded rod 201 is fixedly connected to the lower end surface of the fixed plate 9.

[0044] Specifically, by rotating the rotating disk 204 , the threaded rod 201 can be extended and retracted to drive the fixed platform 7 to perform lifting and lowering fine adjustment.

[0045] Working principle: Pull the knobs 805 located on both sides of the outer wall of the same first bracket 4 to the sides, thereby driving the multiple positioning rods 804 to disengage from the multiple positioning holes 10, and then rotate the second bracket 5 to make it embedded in the first bracket 4 and loosen the two knobs 805. At this time, the two knobs 805 are embedded in the positioning holes 10 under the action of the two springs 802 to fix the rotation angle of the second bracket 5, thereby achieving the flipping and storage effect of the second bracket 5, and rotating the rotating disk 204 drives the threaded sleeve 202 to rotate. Since the telescopic rod 203 can limit the rotation of the fixed plate 9, the threaded sleeve 202 can drive the threaded rod 201 to move up and down and drive the fixed plate 9 to move up and down, thereby achieving the effect of fine-tuning the height of the fixed plate 9 and the surveying and mapping device body 1.
