[0002] A surveying pole is a measuring tool, shaped like a rod, mainly used to indicate measurement points. When in use, the surveying pole usually needs to be fixed at the surveying location. Surveying poles are commonly used in construction and forestry surveys. After forestry planning is completed, poles are generally used to delineate ground points. However, when using surveying poles on-site, it was found that adjusting the pole's height was inconvenient, and rotating the sign frame to the appropriate direction was also difficult. Therefore, we have proposed a new type of on-site surveying pole. Utility Model Content

[0003] The purpose of this utility model is to provide a field marker pole to solve the problems mentioned in the background art, such as the inconvenience of adjusting the height of the marker pole and the inconvenience of rotating the sign frame to the appropriate direction.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a field marker post, comprising a base, a support rod fixedly connected to the middle position of the top of the base, a threaded groove machined at the top of the support rod, a threaded rod provided inside the threaded groove, a first connecting rod fixedly connected to the top of the threaded rod, a movable sleeve sleeved on the outside of the first connecting rod, a movable groove provided inside the movable sleeve, a second connecting rod fixedly connected to the right side of the movable sleeve, a marker frame welded to the right side of the second connecting rod, and limit plates provided at the bottom and top of the movable sleeve.

[0011] Preferably, the diameter of the reserved groove is larger than the diameter of the mounting sleeve, and the fixing rod is disposed inside the reserved groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the on-site marker pole not only makes it easy to adjust the height of the pole and the direction of the sign frame, and makes it easy to replace the sign, but also improves the stability of the pole;

[0013] (1) By setting up a threaded groove, a threaded rod, a first connecting rod, a limiting plate and a movable sleeve, when it is necessary to adjust the overall height of the signpost, rotate the threaded rod. Since the threaded rod and the threaded groove cooperate with each other and the sign frame is installed on the right side of the first connecting rod, rotating the threaded rod can not only adjust the overall height of the signpost but also adjust the height of the sign frame, thereby improving the overall flexibility of the signpost. When it is necessary to adjust the direction of the sign frame, rotate the movable sleeve. The movable sleeve drives the sign frame to rotate through the second connecting rod, thereby adjusting the direction of the sign frame.

[0014] (2) By setting fluorescent strips, fixing pins, mounting grooves, mounting plates and sealing gaskets, when it is necessary to replace the sign inside the sign frame, the fixing pins are taken out from the inside of the fixing groove to make the mounting plate lose its fixation. After the mounting plate loses its fixation, the baffle can be disassembled. After the baffle is disassembled, the sign inside the sign frame can be taken out and replaced. After replacement, the mounting plate is inserted into the inside of the mounting groove again. The sealing gasket can make the baffle fit tightly against the right side of the sign frame, thereby preventing rainwater from entering the inside of the sign frame and protecting the sign inside the sign frame.

[0015] (3) By setting up an installation sleeve, a fixing rod, a handle, a connecting plate and a reserved groove, after placing the base in a suitable position, turn the handle. The handle drives the fixing rod to rotate inside the installation sleeve through the connecting plate, so that the fixing rod can be embedded in the soil to fix the base. When it is inconvenient to turn the handle, put the fixing rod inside the reserved groove, and then press the connecting plate to make the connecting plate drive the fixing rod to descend.

[0021] 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 protection scope of the present utility model.

[0022] Example 1: Please refer to Figure 1-4 A type of on-site marker pole includes a base 1, a support rod 4 fixedly connected to the middle position of the top of the base 1, a threaded groove 5 machined inside the top of the support rod 4, a threaded rod 6 provided inside the threaded groove 5, a first connecting rod 7 fixedly connected to the top of the threaded rod 6, a movable sleeve 21 sleeved on the outside of the first connecting rod 7, a movable groove 22 opened inside the movable sleeve 21, a second connecting rod 8 fixedly connected to the right side of the movable sleeve 21, a marker frame 9 welded to the right side of the second connecting rod 8, and limit plates 20 provided at the bottom and top of the movable sleeve 21.

[0023] The limiting plate 20 is fixedly connected to the outside of the first connecting rod 7. The movable sleeve 21 rotates on the outside of the first connecting rod 7 through the movable groove 22. The threaded groove 5 has an internal thread, and the threaded rod 6 has an external thread that matches the internal thread.

[0024] Specifically, such as Figure 1 and Figure 4As shown, when it is necessary to adjust the overall height of the signpost, rotate the threaded rod 6. Since the threaded rod 6 and the threaded groove 5 cooperate with each other and the sign frame 9 is installed on the right side of the first connecting rod 7, rotating the threaded rod 6 can not only adjust the overall height of the signpost but also adjust the height of the sign frame 9, thereby improving the overall flexibility of the signpost. When it is necessary to adjust the direction of the sign frame 9, rotate the movable sleeve 21. The movable sleeve 21 drives the sign frame 9 to rotate through the second connecting rod 8, thereby adjusting the direction of the sign frame 9.

[0025] Example 2: A fluorescent strip 10 is provided at the front edge of the sign frame 9. A baffle 12 is provided on the right side inside the sign frame 9. A sealing gasket 19 is provided between the baffle 12 and the sign frame 9. An installation plate 18 is fixedly connected to the top left side of the baffle 12. An installation groove 16 is provided on the right side of the top inside the sign frame 9. A fixing groove 17 is provided inside the installation groove 16 and the installation plate 18. A fixing pin 11 is provided inside the fixing groove 17. The installation plate 18 is embedded inside the installation groove 16. The installation plate 18 is fixed inside the installation groove 16 by the fixing pin 11 and the fixing groove 17.

[0026] Specifically, such as Figure 1 and Figure 3 As shown, when it is necessary to replace the sign inside the sign frame 9, remove the fixing pin 11 from the inside of the fixing groove 17 to make the mounting plate 18 unfixed. After the mounting plate 18 is unfixed, the baffle 12 can be removed. After removing the baffle 12, the sign inside the sign frame 9 can be taken out and replaced. After replacement, the mounting plate 18 is inserted back into the inside of the mounting groove 16. The sealing gasket 19 can make the baffle 12 fit tightly against the right side of the sign frame 9, thereby preventing rainwater from entering the inside of the sign frame 9 and protecting the sign inside the sign frame 9.

[0027] Example 3: Mounting sleeves 2 are fixedly connected to both sides inside the base 1. A fixing rod 3 is set inside the mounting sleeve 2. A connecting plate 14 is fixedly connected to the top of the fixing rod 3. A handle 13 is fixedly connected to the left side of the top of the connecting plate 14. A reserved groove 15 is opened at both ends inside the base 1. The mounting sleeve 2 and the fixing rod 3 cooperate with each other. The mounting sleeve 2 is symmetrically distributed about the vertical center line of the base 1. The diameter inside the reserved groove 15 is larger than the diameter inside the mounting sleeve 2. The fixing rod 3 is set inside the reserved groove 15.

[0028] Specifically, such as Figure 1 and Figure 2As shown, after placing the base 1 in a suitable position, turn the handle 13. The handle 13 drives the fixing rod 3 to rotate inside the mounting sleeve 2 through the connecting plate 14, so that the fixing rod 3 can be embedded in the soil to fix the base 1. When it is inconvenient to turn the handle 13, put the fixing rod 3 into the reserved groove 15, and then press the connecting plate 14 to make the connecting plate 14 drive the fixing rod 3 to descend.

[0029] Working principle: In use, the fixing pin 11 is removed from the fixing groove 17, causing the mounting plate 18 to lose its fixation. After the mounting plate 18 is unfixed, the baffle 12 can be disassembled. After disassembling the baffle 12, the sign inside the sign frame 9 can be taken out and replaced. After replacement, the mounting plate 18 is inserted back into the mounting groove 16. The sealing gasket 19 ensures that the baffle 12 fits tightly against the right side of the sign frame 9, thus preventing rainwater from entering the interior of the sign frame 9 and protecting the sign inside the sign frame 9. Replacing the sign can improve the applicability of the signpost. After placing the base 1 in the appropriate position, the handle 13 is turned. The handle 13 drives the fixing rod 3 through the connecting plate 14. Rotating inside the mounting sleeve 2 allows the fixing rod 3 to be embedded in the soil to fix the base 1. When the overall height of the marker needs to be adjusted, the threaded rod 6 is rotated. Rotating the threaded rod 6 can adjust not only the overall height of the marker but also the height of the sign frame 9, thereby improving the overall flexibility of the marker. When the direction of the sign frame 9 needs to be adjusted, the movable sleeve 21 is rotated. The movable sleeve 21 drives the sign frame 9 to rotate through the second connecting rod 8, thereby adjusting the direction of the sign frame 9. When it is inconvenient to rotate the handle 13, the fixing rod 3 is placed inside the reserved groove 15, and then the connecting plate 14 is pressed to make the connecting plate 14 drive the fixing rod 3 to descend. The reserved groove 15 and the mounting sleeve 2 are provided to increase the possibility of fixing.
