[0025] 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 scope of protection of the present utility model.

[0026] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0027] This application discloses a surveying support structure adapted to terrain. (Refer to...) Figure 1 and Figure 9A terrain-adaptive measuring support structure includes a measuring mounting base 1. A swing block 13 is rotatably connected to the bottom of the measuring mounting base 1. A swing bracket 4 is fixedly connected to the bottom of the swing block 13. A switching mechanism 5 is provided at the bottom of the swing bracket 4. The switching mechanism 5 includes a mounting head 501, which is fixedly connected to the top of the swing bracket 4. A mounting block 508 is fixedly connected to the inner wall of the mounting head 501. A rotating support rod 506 is rotatably connected to the inner wall of the mounting block 508. A needle support head 505 is fixedly connected to one side of the rotating support rod 506. A support base 503 is fixedly connected to one side of the rotating support rod 506. A rotating wheel support head 504 is fixedly connected to one side of the rotating support rod 506. The mounting block 508, the needle support head 505, and the inner wall of the mounting head 501 slide against each other. A sliding bearing 507 is movably connected, and a pull rod 502 is fixedly connected to one side of the sliding bearing 507. A limiting plate 510 is fixedly connected to the surface of the sliding bearing 507, and a spring 509 is provided on the surface of the limiting plate 510. The swing bracket 4 installed at the bottom of the measuring mounting base 1 can drive the mounting head 501 to swing, so that the three limiting plates 510 unfold to support the measuring mounting base 1. The rotating support rod 506 installed in the mounting head 501 can adjust different types of support heads according to the environment. The sliding bearing 507 fixes the needle support head 505 under the elastic force of the spring 509, thereby increasing the firmness between the mounting head 501 and the pull rod 502. The limiting plate 510 installed on the surface of the sliding bearing 507 can limit the sliding bearing 507 to the mounting block 508.

[0028] Reference Figure 1 The top of the measuring mounting base 1 is fixedly connected to the measuring mounting plate 2, and the top of the measuring mounting plate 2 is fixedly connected to the mounting column 3, which can be directly connected to the measuring instrument, making it convenient to carry the measuring instrument and the bracket separately, and avoiding collision between the measuring instrument and the ground during the carrying process;

[0029] Reference Figure 1 An observation box 11 is fixedly connected to one side of the measuring mounting base 1. A rotating bead 12 is provided inside the observation box 11. When the measuring mounting base 1 is supported on the ground by the needle support head 505, the user can judge the verticality between the measuring mounting base 1 and the ground by the position of the rotating bead 12 inside the observation box 11.

[0030] Reference Figure 1 The bottom of the measuring mounting plate 2 is fixedly connected to the mounting rod 16, and the bottom of the mounting rod 16 is fixedly connected to the docking block 7. The surface of the swing bracket 4 is fixedly connected to the mounting collar 6. The docking block 7 and the mounting collar 6 are rotatably connected to the telescopic link 8. When the mounting head 501 is unfolded, the telescopic link 8 can assist the swing bracket 4 and increase the stability of the swing bracket 4, the measuring mounting base 1 and the ground.

[0031] Reference Figure 1 The top of the swing block 13 is fixedly connected to a chuck 14, and a chuck rod 15 is slidably connected between the chuck 14 and the measuring mounting base 1. When the swing bracket 4 swings, the chuck rod 15 can pass through the round hole of the corresponding structure, so that the swing bracket 4 can be fixedly installed within the unfolded range.

[0032] Reference Figure 1 A fixing rod 9 is fixedly connected to the surface of the measuring mounting base 1, and a placement plate 10 is fixedly connected to the bottom of the fixing rod 9, which can be used to place the installation tools of the measuring instrument depending on the usage.

[0033] Reference Figure 9 A magnetic block 17 is fixedly connected to the bottom of the mounting block 508, and a mating magnetic block 18 is fixedly connected to the top of the needle support head 505. When the needle support head 505 rotates to the installation position of the sliding card shaft 507, the magnetic block 17 and the mating magnetic block 18 will attract and connect with each other to assist in the installation of the rotating support rod 506.

[0034] Working principle: When the measuring mounting base 1 needs to be fixed on a damp and soft ground, the movable pull rod 502 causes the sliding retaining shaft 507 to release the needle support head 505. Then, rotating the support rod 506 causes the needle support head 505 to move downwards. After releasing the pull rod 502 again, the sliding retaining shaft 507, under the elastic force of the spring 509, locks the needle support head 505. The retaining rod 15 unfolds the swing bracket 4, inserts the needle support head 505 into the ground, and then inserts the retaining rod 15 into the round hole on the surface of the measuring mounting base 1 and the retaining wheel 14, thereby allowing the measuring mounting base to be fixed on the ground. The base 1 is fixed on the ground. The user can observe the position of the rotating bead 12 in the observation box 11. When the rotating bead 12 is in the middle of the observation box 11, the measuring mounting base 1 is perpendicular to the ground. When the rotating bead 12 is not in the middle range, it means that the measuring mounting base 1 is not perpendicular to the ground. When it is necessary to fix the measuring mounting base 1 on a solid road surface, the support base 503 or the rotating wheel support head 504 can be replaced. Replacing the support base 503 can increase the firmness between the swing bracket 4 and the ground. Replacing the rotating wheel support head 504 makes it easier for the user to move the measuring mounting base 1.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
