[0002] In the preparation for surveying and mapping operations, it is necessary to set up the surveying and mapping bracket on a relatively stable ground, keep its mounting platform as horizontal as possible, and then install the surveying instrument on its mounting platform, so as to fine-tune and level the surveying instrument and proceed to the next step of surveying and mapping. However, in outdoor environments such as mountains and fields with harsh environments, it is difficult to set up the surveying and mapping bracket in a state close to horizontal, which results in a large angle range for the surveying and mapping instrument to be adjusted, which can easily affect the stability of the surveying and mapping bracket during the surveying and mapping process. If the surveying and mapping bracket is tilted after exceeding the fine-tuning range and being adjusted, it is necessary to readjust the setting position of the surveying and mapping bracket, which affects the progress of the surveying and mapping work. Based on this, it is necessary to provide a bracket that can overcome the harsh ground environment and perform stable surveying and mapping in it. Utility Model Content

[0016] In order to better understand the purpose, structure and function of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings.

[0017] like Figure 1 , Figure 2As shown, the utility model provides a stable surveying and mapping bracket, including a mounting platform for mounting a surveying and mapping instrument and legs 1 evenly arranged on the lower surface of the platform for erecting the mounting platform. In order to enable the surveying and mapping bracket to adapt to the harsh uneven ground environment, in this embodiment, the mounting platform is arranged as an axial rotating part and a radial swinging part arranged on the axial rotating part, and a mounting hole 12 for mounting the surveying and mapping instrument is arranged in the middle of the radial swinging part. Here, the mounting hole 12 can be a through hole with or without threads, which is specifically determined according to the installation method of the surveying and mapping instrument and is not limited in this embodiment. Importantly, the axial rotating part uses the center surrounded by the legs 1 as the rotation axis, and the radial swinging part uses the center surrounded by the legs 1 as the swing axis.

[0018] Specifically, Figure 1 , Figure 2 As shown, the axial rotating part includes a mounting base 2, a bearing 3 and a swing mounting platform 4 from bottom to top, the leg 1 is hingedly mounted on the lower surface of the mounting base 2 through a hinge ear 13, and the swing mounting platform 4 is arranged on the mounting base 2 through a bearing 3, preferably a plane thrust bearing. In addition, in order to connect the three as a whole, as shown in FIG. Figure 3 As shown, in this embodiment, the side of the mounting base 2 is higher than the plane on which the swing mounting platform 4 is mounted, forming a receiving groove capable of placing the swing mounting platform 4, and a concave ring 8 is provided on the side of the swing mounting platform 4, and a plurality of dot-shaped protrusions 9 that can be inserted into the concave ring 8 are evenly provided on the side of the mounting base 2. After the plane thrust bearing and the swing mounting platform 4 are sequentially placed into the receiving groove of the mounting base 2, pressure is applied to the swing mounting platform 4, so that the protrusions on the side of the mounting base 2 can be inserted into the concave ring 8 on the side of the swing mounting platform 4, so that the three are connected as one.

[0019] In addition, if Figure 1 As shown, in order to facilitate assembly, the upper surface of the swing mounting platform 4 is provided with a mounting groove for mounting the radial swing part, and the radial swing part is arranged on the swing mounting platform 4 through the mounting groove.

The cover plate 7 is arranged above the arc ring 5 and fixed to the swing mounting platform 4 by bolts. In addition, in order to facilitate the swinging of the surveying and mapping mounting plate 6, the mounting groove is arranged in an arc shape that matches the arc surface of the arc ring 5. At the same time, the arc surface of the arc ring 5 and the mounting groove are frictionally matched to increase the resistance between the two, so as to provide resistance and keep the surveying and mapping instrument level after the surveying and mapping instrument is installed and leveled. When the support leg 1 is erected on a rugged ground and the mounting platform tilts, the user only needs to rotate the swing mounting platform 4 to drive the swing direction of the radial swinging part thereon to be the same as the tilt direction of the bracket body, and then adjust the surveying and mapping mounting plate 6 in the direction opposite to the tilt direction, so that the surveying and mapping mounting plate 6 can be adjusted to be horizontal or nearly horizontal.

[0020] Further, such as Figure 1 As shown, in order to facilitate setting and adjustment, and to improve the stability of the surveying and mapping bracket during use, the number of arc rings 5 ​​in this embodiment is two, and the two arc rings 5 ​​are mirror-imaged along the axis of the swing mounting platform 4. At the same time, in order to further expand the leveling range of the surveying and mapping bracket and to facilitate storage, the legs 1 are selected to be telescopic in this embodiment, and the lower ends of the legs 1 are fixed with foot nails 10 to facilitate the installation and positioning on uneven ground. At the same time, in order to install the surveying and mapping bracket on the bottom surface with soil, a foot pedal 11 is also fixed on the side of the lower end of the leg 1 in this embodiment. When the surveying and mapping bracket is installed on the ground with soil, it is only necessary to step on the foot pedal 11 to drive the foot nail 10 into the soil.
