Description

Technical Field

[0001] The utility model relates to the technical field of engineering surveying, and particularly relates to a surveying rod for engineering surveying. Background Art

[0002] A surveying rod is a measuring tool made of wooden or iron rods, painted with red and white paint or scales. The bottom of the surveying rod is generally conical, which is convenient for staff to set it up on the ground for measurement. It is mainly used to indicate the measurement point, generally used in construction engineering surveying operations, facilitating construction workers to operate quickly, so as to achieve the purposes of effective measurement positioning, ensuring operation quality, and working efficiency.

[0003] According to a surveying rod for engineering surveying with the application number 202321719143.9, when in use, first place the device on the ground for surveying and mapping, and then make the surveying rod body in a free state. At this time, record the angle scale value on the support top plate. The calculation method is the deviation angle between the surveying rod body and the midline of the angle scale value. Then adjust the angle adjustment mechanism to make the angle adjustment mechanism rotate in the opposite direction by the corresponding angle. Finally, lower the surveying rod body through the telescopic rod to fix the surveying rod body on the top of the angle adjustment mechanism. At this time, the surveying rod body is in a vertical state, and the measurement is more accurate.

[0004] However, the above-mentioned surveying rod for engineering surveying has certain deficiencies. Firstly, it is necessary to adjust the surveying rod to a vertical state for measurement in a relatively cumbersome manner during use, and the operation is relatively inconvenient. In addition, it is relatively inconvenient to disassemble and install the surveying rod on the device, and it is relatively inconvenient to carry. Therefore, we propose a surveying rod for engineering surveying. Content of the Utility Model

[0013] 1. For this benchmark for engineering surveying, through the cooperation of the swivel base, spherical groove, spherical joint, connecting rod, plumb bob, threaded hole and threaded joint, during measurement, only need to thread the benchmark body with the threaded joint at the bottom of the plumb bob through the threaded hole to complete the installation. Then, due to the gravity of the plumb bob itself, the benchmark body can be in a vertical state, which is convenient for measurement, and there is no need for cumbersome adjustment operations, and the operation is convenient and fast.

[0014] 2.

A threaded hole 13 is opened inside the bottom of the hanging cone 12. A threaded joint 14 is fixedly installed at one end of the benchmark body 2. The threaded joint 14 cooperates with the threaded hole 13.

[0023] A limit sleeve 15 is fixedly installed on one side of the support rod 3. A hole matching the benchmark body 2 is opened inside the limit sleeve 15. A rubber ring is arranged on the inner side of the limit sleeve 15. The rubber ring on the inner side of the hole of the limit sleeve 15 is used to limit and buffer the benchmark body 2.

It is convenient for measurement and does not require cumbersome adjustment operations, with convenient and fast operation. When not in use, first disassemble the benchmark body 2 from below the hanging cone 12. Then, insert the benchmark body 2 into the limiting sleeve 15 and the jacking hole 16. Subsequently, by pulling up the pressing plate 19, the sliding sleeve 17 slides upward on the outer side of the sliding rod 4 while squeezing the spring 18. Then, rotate the sliding sleeve 17 to make the pressing seat 20 rotate above the threaded joint 14, and then release the pressing plate 19. After the spring 18 rebounds, the benchmark body 2 can be pressed and fixed on one side of the support rod 3 through the cooperation of the pressing seat 20 and the limiting hole 21 with the threaded joint 14. Moreover, the mounting sleeve 6 can be disassembled from the sleeve rod 5, facilitating overall carrying and use.
