RTK flow station centering rod is an important tool in the surveying and mapping process, which is mainly used to support and fix GPS antenna to ensure the accuracy of measurement. The traditional RTK flow station centering rod has some shortcomings in the use process. For example, it is difficult to maintain a stable vertical state on uneven terrain, especially when the operator is performing centering operation, he has to perform single-handed operation due to the influence of the operation manual or other factors, at the same time, the operation manual placed on the RTK flow station centering rod makes its center of gravity unstable, these factors lead to low centering efficiency and deviation of measurement results. In addition, the existing centering rod has limited ability to adapt to different terrain and use environment, and lacks effective auxiliary balancing mechanism to improve its stability and adaptability.

Therefore, a new type of surveying and mapping RTK flow station centering rod is needed, which can maintain stability in different terrain and use environment, improve centering efficiency and measurement accuracy and reliability, and has good portability and adjustability.

The assembly structure can be a threaded column structure or the like.

[0053] As known in the art, a length / height identification scale is further arranged on the adjusting rod, a clamp for fixing the adjusting rod is arranged on the functional pedestal 120, the clamp is clamped and fixed and loosened through a screw rod and an adjusting knob, and a plurality of insertion holes are further arranged on the adjusting rod, the insertion holes are arranged at intervals along the length direction of the adjusting rod, and an insertion pin is arranged on the functional pedestal 120, the insertion pin is connected with the functional pedestal 120 through a rope, and by inserting the insertion pin into the insertion hole of the adjusting rod, the adjusting rod can be prevented from falling back into the operating rod. The above structure and configuration are all known in the art, and will not be specifically limited and described here.

[0054] It should be noted that, please refer to Figure 2 , the bottom end of the operating rod (i.e. the second end of the centering rod main body 110) is a tapered portion 111, the tapered portion 111 comprises a coaxially arranged small cylindrical segment 1111 and a conical segment 1112, and the length of the cylindrical segment 1111 is less than the length of the conical segment 1112.

[0055] In the present embodiment, please refer to Figure 1 and Figure 2 , in order to improve the structural stability of the centering rod, improve the centering efficiency and the accuracy and reliability of the measurement, the second end of the centering rod body 110 in the present embodiment is also provided with an auxiliary balancing mechanism 300, the auxiliary balancing mechanism 300 includes x support components 310, the support components 310 are arranged on the conical side of the centering rod body 110 along the radial direction of the centering rod body 110, the support components 310 include a connecting section 311 and a support section 312 arranged in sequence, the end of the support section 312 away from the connecting section 311 is a support end, the connecting section 311 is fixedly connected with the conical part 111 (specifically the cylindrical section of the conical part 111) of the centering rod body 110, the height of the support component 310 along the axial direction of the centering rod is equal to the length of the conical part 111, the support section 312 can elastically stretch and contract along its own axial direction under the action of external force applied along its own axial direction, the support section 312 is arranged in an inclined manner relative to the centering rod body 110 in a direction away from the centering rod body 110, the included angle between the axis of the support section 312 and the axis of the centering rod body 110 is an acute angle, and the support end and the conical tip of the conical part 111 are located in the same plane.

[0056] By arranging the elastically stretchable support components 310, auxiliary support and balance can be provided for the centering rod. Specifically, by arranging the support components 310, the number of contact points / area of the contact area between the centering rod and the ground or other base body is increased, and the central position of the centering rod as a whole is lowered, thereby improving the structural stability of the centering rod when it is erected, and when leveling the bubble of the level on the centering rod, the centering rod needs to be offset / oscillate relative to its own central axis with the conical tip as the center. Since the support section 312 of the support component 310 is inclined outward in a direction away from the centering rod body 110, when the centering rod is offset / oscillates to the side where the support component 310 is located, the support component 310 provides a counteracting force for the centering rod through its elastic stretching and contraction, thereby reducing the offset / oscillation amplitude of the centering rod, achieving fine adjustment during leveling. Even when operating with one hand or a load, precise and small-amplitude adjustment of the centering rod can be achieved, and thus the leveling of the bubble of the level can be quickly achieved.

[0057] It should be noted that, please refer to Figure 2 , the support component 310 is fixedly connected with the cylindrical section 1111 of the conical part 111 of the centering rod body, and in the axial direction of the centering rod body, the axial length L of the support component 310 as a whole is less than or equal to the axial length of the conical part 111, but greater than the axial length of the conical section 1112.

[0058] In the present embodiment, please refer to Figure 1 , Figure 3 , Figure 4The number x of the supporting components 310 can be 1, 2, 3, or the like. Specifically, when the number of the supporting components 310 is more than two, the supporting ends of all the supporting components 310 are located on the same circumference, and the center of the circumference is located at the conical tip of the centering rod body 110. It can be understood that when the number of the supporting components 310 is three and the supporting components 310 are distributed at equal intervals around the circumference of the centering rod body 110, the optimal solution can be achieved in terms of structure simplification, auxiliary balance, cost, and the like.

[0059] In the embodiment, please refer to Figure 5 The supporting section 312 includes a first supporting column 3121, a second supporting column 3122, and a buffer spring 3123. The first supporting column 3121 has an assembly hole 3124 in the interior. A part of the second supporting column 3122 is arranged in the assembly hole 3124 and movably cooperates with the first supporting column 3121. The buffer spring 3123 is arranged in the assembly hole 3124 and is fixedly connected with the first supporting column 3121 and the second supporting column 3122, respectively. The first supporting column 3121 is fixedly connected with the connecting section 311. The end of the second supporting column 3122 away from the first supporting column 3121 serves as a supporting end. When the supporting component 310 is subjected to an acting force (generally, the acting force is the compression generated when the centering rod body 110 swings / tilts, and the acting force is also the main force or the component force) in the axial direction of the supporting section 312, the buffer spring 3123 is compressed and recoverable compression occurs, so that the supporting section 312 / the supporting component 310 as a whole presents elastic expansion and contraction.

[0060] In the embodiment, please refer to Figure 5In order to limit the telescopic length / distance of the support section 312 / support component 310, a stroke limiting structure is further arranged between the first support column 3121 and the second support column 3122, which is used to limit the maximum telescopic distance of the relative movement of the first support column 3121 and the second support column 3122 along their own axes, and the maximum telescopic distance of the relative movement of the first support column 3121 and the second support column 3122 along their own axes is less than the maximum compression deformation amount of the portion of the buffer spring 3123 axially located between the first support column 3121 and the second support column 3122, so as to avoid excessive compression damage to the spring, and at the same time, limiting the telescopic length / distance of the support section 312 / support component 310 can also reduce the amplitude of the swing / tilt of the centering rod allowed in the alignment process, thereby ensuring the adjustment amplitude of the leveling, and reducing the adjustment range of the leveling. Specifically, the maximum telescopic distance of the relative movement of the first support column 3121 and the second support column 3122 along their own axes is not more than 1 / 3 of the axial length of the telescopic section. In the embodiment, the stroke limiting structure includes a first stop protrusion 3125 and a second stop protrusion 3126, the first stop protrusion 3125 is fixedly arranged on the inner wall of the assembly hole 3124 of the first support column 3121, the second stop protrusion 3126 is arranged on the second support column 3122, the first stop protrusion 3125 and the second stop protrusion 3126 are located on the same side away from the buffer spring 3123, the first stop protrusion 3125 is arranged on the side of the second stop protrusion 3126 close to the buffer spring 3123, and the first stop protrusion 3125 and the second stop protrusion 3126 can abut along the axis of the support section 312, thereby limiting the stroke of the relative movement of the first support column 3121 and the second support column 3122 along their own axes, and the first distance between the first stop protrusion 3125 and the second stop protrusion 3126 is the maximum telescopic distance of the relative movement of the first support column 3121 and the second support column 3122 along their own axes. It can be understood that the inner ring of the first stop protrusion 3125 has a diameter slightly larger than the diameter of the second support column 3122, and the portion of the second support column 3122 in the assembly hole 3124 is in sliding contact with the inner ring surface of the first stop protrusion 3125, so as to ensure the smoothness of the telescopic movement of the support component 310.

[0061] In the embodiment, please refer to Figure 6In order to improve the structural stability of the support component 310 and avoid the first support column 3121 and the second support column 3122 from being separated, a third stop protrusion 3127 is arranged on the inner wall of the assembly hole 3124 of the first support column 3121, the third stop protrusion 3127 is annular, the first stop protrusion 3125 and the third stop protrusion 3127 are arranged along the axial direction of the first support column 3121, the second stop protrusion 3126 is located between the first stop protrusion 3125 and the third stop protrusion 3127, and the third stop protrusion 3127 and the second stop protrusion 3126 can abut along the axial direction of the support section 312, so as to avoid the second support column 3122 from being separated from the assembly hole 3124 of the first support column 3121 along the axial direction, thereby improving the structural strength and the structural stability of the support structure.

[0062] In the embodiment, in order to further improve the structural stability and the sealing performance of the support component 310, a flexible bellows sleeve (for example, a light and thin rubber bellows sleeve) is further sleeved outside the support component 310, one end of the bellows sleeve is fixedly and sealingly connected with the first support column 3121, and the other end is fixedly and sealingly connected with the second support column 3122, that is, the support component 310 can be stretched and contracted, and the gap part between the first support column 3121 and the second support column 3122 is encapsulated in the bellows sleeve.

[0063] In the embodiment, in order to improve the comprehensiveness of the centering rod adjustment, the x support components 310 are the same in the size and the structure, but the maximum stretching and contracting distances of the x support components 310 are different, specifically, the structural strength or the length of the buffer spring 3123 contained in the x support components 310 is different, so as to provide different elastic restoring forces.
