[0029] Many modifications and variations of the present application described in the specification are possible in light of the above teachings. Other implementations of the present application will be apparent to those skilled in the art from consideration of the specification and practice of the application disclosed herein. For example, one of ordinary skill in the art will understand that the acts of methods presented and / or illustrated herein can be performed in an order different than that which is presented or illustrated herein. One of ordinary skill in the art will also understand that the ordering of the above-described acts can be changed or that additional acts can be added or that other implementations of the application can be adapted to include different or additional acts.

[0030] The present application provides a surveying instrument with a stable standing structure, which comprises a stable plate assembly, a centering rod, a connecting rod, a fastening adjusting assembly, a GPS unit and a leveling assembly. Figures 1-4The structure of the measuring instrument is shown. In the embodiment, the measuring instrument comprises a stabilizing plate assembly 1, a centering rod 2, and a connecting rod 3. The lower ends of the plurality of connecting rods 3 are movably connected to the stabilizing plate assembly 1, and the upper ends of the connecting rods 3 are fixedly connected to the centering rod 2 through a fastening and adjusting assembly 4.

[0031] The lower end 21 of the centering rod 2 is in contact with the stabilizing plate assembly 1 and can limit the relative position of the lower end 21 of the centering rod 2 and the stabilizing plate assembly 1. The upper end 22 of the centering rod 2 is provided with a GPS unit 5 for measurement positioning.

[0032] In the embodiment, the stabilizing plate assembly 1 comprises a base stabilizing plate 11 and a folding stabilizing plate 12. Preferably, the material is light in weight and high in strength and buoyancy, so that the measuring instrument can be used on water or in a place capable of generating buoyancy, and the position of the measuring instrument can be prevented from being lowered due to the weight of the measuring instrument.

[0033] Each side of the base stabilizing plate 11 is movably connected to the folding stabilizing plate 12 through a clasp spring 13. In the embodiment, the base stabilizing plate 11 is a rectangular or square plate, and the four sides are movably connected to the folding stabilizing plate 12 through the clasp springs 13.

[0034] The clasp spring 13 can clamp the unfolded folding stabilizing plate 12 relative to the base stabilizing plate 11 to form a larger-area stabilizing plate structure, and the folding stabilizing plate 12 will not be folded under certain external force. When a certain pressure is applied to the clasp spring 13, the clasp spring 13 can cancel the clamping state of the folding stabilizing plate 12 relative to the base stabilizing plate 11, and restore the folding state of the folding stabilizing plate 12 relative to the base stabilizing plate 11.

[0035] Further, a centering stabilizing hole 14 is arranged at the upper axial position of the base stabilizing plate 11. The shape of the centering stabilizing hole 14 corresponds to the shape of the lower end 21 of the centering rod 2, and the bottom of the centering stabilizing hole 14 is the lower side of the base stabilizing plate 11. As shown in the figure, in the embodiment, the lower end 21 of the centering rod 2 is a conical structure, and the centering stabilizing hole 14 is a corresponding conical hole structure. Figure 4

[0036] Further, a plurality of horizontal assemblies 6 for detecting whether the base stabilizing plate 11 is placed in a horizontal state are arranged on the upper side of the base stabilizing plate 11. The horizontal assemblies 6 can quickly detect and adjust the levelness of the base stabilizing plate 11 before measurement, so as to ensure the perpendicularity of the centering rod 2 and the measurement accuracy. Preferably, the horizontal assembly 6 is a bubble level.

[0037] ​In a specific embodiment of this utility model, each corner of the foundation stabilizing plate 11 is respectively hinged to the lower end of a connecting rod 3, and the upper end of each connecting rod 3 is hinged to the fastening adjustment assembly 4. Therefore, the upper end of the connecting rod 3 is close to the central axis of the foundation stabilizing plate 11, and the fastening adjustment assembly 4 is positioned above the central axis of the foundation stabilizing plate 11.

[0038] Furthermore, the fastening adjustment assembly 4 includes a fastening ring 41 and a fastener 42. The fastening ring 41 is a circular ring structure, and the fastening ring 41 is movably hinged to the upper end of the connecting rod 3.

[0039] The fastener 42 is threaded into a threaded hole on the side wall of the fastening ring 41, and its length is adjusted radially along the fastening ring 41. Preferably, the fastener 42 is a fastening screw.

[0040] The centering rod 2 passes through the fastening ring 41 and is fixed by the adjusting fastener 42.

[0041] Furthermore, the connecting rod 3 is a telescopic rod. By adjusting the length of the connecting rod 3, the fastening adjustment component 4 can be fixed at different heights to the centering rod 2, thus providing a stable connection with the centering rod 2. In addition, it can also accommodate centering rods 2 of different lengths. When the centering rod 2 is longer, it needs to extend upwards from the fixed position of the fastening adjustment component 4 to provide stable support and fixation.

[0042] Furthermore, the connecting rod 3 also has a connecting rod locking structure for locking the extension and retraction of the connecting rod 3, so as to prevent the length of the connecting rod 3 from changing when fixing the centering rod, thus affecting the verticality of the centering rod.

[0043] The connecting rod 3 has a scale, which allows for precise adjustment of the length of the connecting rod 3, avoiding the situation where multiple connecting rods have different lengths, thereby avoiding affecting the perpendicularity of the centering rod 2 and the measurement accuracy.

[0044] The above description is merely an illustrative embodiment of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model shall fall within the scope of protection of this utility model.
