DETAILED DESCRIPTION

[0039] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices consistent with some aspects of the present disclosure as detailed in the appended claims.

[0040] 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. 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.

[0041] Embodiment 1:

[0042] like Figures 1 to 6 As shown, this embodiment proposes a field benchmark, including a base shell 1, a benchmark 2, a control component 3, an adjustment component 4, a drive component 5, a lifting plate 7, an installation box 8, a support rod 9, a hinge ball 10 and a hinge groove 13 opened at the lower end of the benchmark 2.

[0043] Among them, a square bottom shell 1 with a hollow interior and an open bottom is used as the basis for installation. A retaining ring is provided inside the lower end of the bottom shell 1. A lifting plate 7 that can move up and down is provided inside the bottom shell 1. The lifting plate 7 moves up and down inside the bottom shell 1. The retaining ring at the lower end of the bottom shell 1 prevents the lifting plate 7 from falling from the inside of the bottom shell 1. It can only be lifted and lowered within a certain range inside the bottom shell 1. Four evenly distributed first hinge supports 301 are fixedly connected to the top of the inside of the bottom shell 1, and four evenly distributed second hinge supports 302 are fixedly connected to the upper side of the lifting plate 7. The first hinge supports 301 and the second hinge supports 302 are cross-distributed. An L-shaped driving bent rod 303 is hinged on the four first hinge supports 301, and the shorter sides of the driving bent rods 303 are A straight connecting rod 304 is hinged, and the second hinge support 302 and the driving bent rod 303 are connected together through the connecting rod 304. As the driving bent rod 303 rotates around one end connected to the first hinge support 301, the lifting plate 7 can be driven by the connecting rod 304 to move up and down inside the bottom shell 1. A universal wheel 12 is fixedly connected to the front, back and both sides of the lower side of the lifting plate 7. When the lifting plate 7 moves downward, it can extend the universal wheel 12 to the outer lower side of the bottom shell 1 when it drops to the bottom, so that the universal wheel 12 can contact the ground, which is convenient for moving the benchmark 2. After the benchmark 2 moves into place, the lifting plate 7 is raised, and the universal wheel 12 is retracted into the interior of the bottom shell 1, so that the outer lower side of the bottom shell 1 contacts the ground, ensuring the stability of the benchmark 2.

[0044] The longer side of the driving bent rod 303 is connected to the inside of the first hinge support 301, and a worm gear 502 is fixedly connected thereto. The worm gear 502 and the internal rotation of the first hinge support 301 are connected together, and the driving bent rod 303 is driven to rotate by the worm gear 502. A worm 501 is rotationally connected to the middle position of the top inner part of the bottom shell 1, and the four rotate inside the first hinge support 301. The worm gear 502 connected to the driving bent rod 303 are all meshed with the worm 501. The worm gear can drive the worm wheel to rotate, and conversely the worm wheel cannot drive the worm to rotate. The one-way driving characteristic enables the driving bent rod 303 to self-lock and revolve around the hinged end of the first hinge support 301, so as to perform a self-positioning lifting and lowering operation on the lifting plate 7. The worm gear 501 is controlled and rotated by a servo motor 503 installed in the middle of the upper end of the bottom shell 1. Under the action of the limiting mechanism 6, the lifting plate 7 can only move up and down inside the bottom shell 1.

[0045] An installation box 8 is fixedly connected to the upper end of the outer side of the bottom shell 1, and the installation box 8 protects the servo motor 503 at the upper end of the outer side of the bottom shell 1, and a vertical support rod 9 is fixedly connected to the upper end of the installation box 8, and a hinge ball 10 is fixedly connected to the upper end of the support rod 9. A benchmark 2 is arranged on the upper side of the outer side of the installation box 8, and a hinge groove 13 is provided at the lower end of the benchmark 2. The hinge ball 10 is stuck in the hinge groove 13, and the benchmark 2 can be tilted in all directions of the horizontal plane. Three evenly distributed connecting rods 11 are fixedly connected to the upper end of the bottom shell 1, and a connecting sleeve 402 is hinged at the upper end of each connecting rod 11. A mounting ring block 14 is provided, and three evenly distributed screw rods 401 are provided at the outer lower end of the mounting ring block 14. The upper ends of the screw rods 401 are hinged to the outer lower side of the mounting ring block 14. A nut 403 which is sleeved on the screw rod 401 and threadedly connected to the screw rod 401 is rotatably connected to the end of the connecting sleeve 402 away from the connecting rod 11. By rotating the nut 403, the length of the mounting screw rod 401 penetrating into the interior of the connecting sleeve 402 can be adjusted, and the inclination of the benchmark 2 can be adjusted. Three evenly distributed universal bubble levels 15 are provided on the outer upper side of the mounting ring block 14. By adjusting the three screw rods 401, the benchmark 2 can be easily leveled.

[0046] Embodiment 2:

[0047] The solution in Example 1 is further introduced below in combination with a specific working method, as described below:

[0048] In order to prevent the lifting plate 7 from tilting inside the bottom shell 1 and ensure that the lifting plate 7 can be lifted and lowered smoothly inside the bottom shell 1, limit bars 601 are fixedly connected to the front, back and both sides of the bottom shell 1, and limit grooves 602 that can be clamped on the outside of the limit bars 601 are provided on the front, back and both sides of the lifting plate 7. The limit grooves 602 are clamped on the outside of the limit bars 601 to ensure the smooth lifting and lowering of the lifting plate 7.

[0049] The electrical components appearing in this article are all connected to an external main controller and 220V AC power, and the main controller can be a conventional known device that controls a computer, etc. The specific implementation method of the present disclosure omits the detailed description of known functions and known components. To ensure the compatibility of the equipment, the operating methods used are consistent with the parameters of marketed equipment.

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