Abstract
Description
Technical Field
[0001] This utility model is a point-locating device for land management surveying, belonging to the field of land surveying technology. Background Technology
[0002] In land surveying operations, positioning rods with helical blades are the core tools for setting up positioning points: the sharp tip at one end of the rod, combined with the rotating cutting force of the helical blades, can easily drill into the soil and quickly mark the positioning points, providing accurate benchmarks for subsequent measurement data collection. However, the storage of these positioning rods when not in use poses significant challenges to operational safety and tool maintenance.
[0003] Because land surveying often requires setting up multiple positioning points, a large number of positioning rods need to be carried during operations. These rods are typically stored together in toolboxes, storage bags, or temporarily stacked next to the work vehicle. However, the pointed ends of the rods are always exposed, lacking effective protection, and easily become a source of danger during storage. Firstly, if the pointed ends collide with metal parts in the toolbox, other surveying tools (such as leveling instrument accessories, tape measure hooks), or accidentally hit the ground or vehicle metal frames during transport, the edges of the pointed ends can easily chip, deform, or even become blunt. The integrity of the pointed ends directly affects the efficiency of the positioning rod's insertion into the soil. Secondly, the exposed pointed ends pose a direct safety threat to personnel and equipment. When workers handle or organize positioning rods, their hands are easily cut by the sharp edges if they accidentally touch the pointed end. If the storage container tipps over, the rolling positioning rod may hit the ground with the pointed end facing down, or even puncture work clothes, tires, etc. More seriously, if the pointed end accidentally touches a measuring instrument (such as the lens of a total station or the observation window of a level), it will directly damage precision components, causing instrument failure, measurement interruption, and high maintenance costs. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a land management surveying point locator to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a land management surveying pinpoint device, comprising:
[0006] The rod body has helical blades installed on its outer surface. A top plate is installed at one end of the rod body. A plug-in lug is installed in the middle of the side of the top plate facing away from the rod body. A pointed end is installed at the end of the rod body away from the top plate.
[0007] The pad has a perforation on one side, and the pointed end is inserted into the perforation. The pad is connected to the top plate by a connector.
[0008] Furthermore, the connector includes a semi-threaded screw. Two semi-threaded screws are installed on the side of the pad facing the top plate, which are symmetrically arranged about the rod body. Two round holes are opened on the side of the top plate facing the pad. The end of the semi-threaded screw away from the pad passes through the round hole. A limiting ring is provided on the side of the round hole facing the pad. The limiting ring is sleeved on the semi-threaded screw and connected and fixed to the semi-threaded screw. A nut that is threadedly connected to the semi-threaded screw is provided on the side of the round hole away from the limiting ring.
[0009] Furthermore, a first plug rod is installed at the center of the side of the top plate adjacent to the plug ear. A first plug hole is formed by a recess on the side of the top plate opposite to the first plug rod. The first plug rod on one top plate is inserted into the first plug hole on the other top plate. Two second plug rods are installed on one side of the pad. Two second plug holes are opened on the side of the pad opposite to the second plug rods. The second plug rod on one pad is inserted into the second plug hole on the other pad.
[0010] Furthermore, a first blocking ring is sleeved on the first plug rod and fixedly connected to the first plug rod. The outer diameter of the first blocking ring is larger than the inner diameter of the first plug hole. A second blocking ring is sleeved on the plug rod and fixedly connected to the second plug rod. The outer diameter of the second blocking ring is larger than the inner diameter of the second plug hole.
[0011] Furthermore, a first conical head is installed at the end of the first plug rod away from the top plate, and the first conical head and the first plug rod are integrally formed. A second conical head is installed at the end of the second plug rod away from the pad block, and the second conical head and the second plug rod are integrally formed.
[0012] Furthermore, the side of the pad opposite to the semi-threaded screw is recessed to form two grooves, the second insertion hole communicates with the grooves, and a support sleeve is installed on the inner wall of one of the grooves, which is concentrically arranged with the second insertion hole. A rubber sleeve is glued inside the support sleeve, and the rubber sleeve wraps around the second insertion rod.
[0013] Furthermore, a first positioning hole is formed by a recess in the middle of the side of the top plate adjacent to the plug ear, and one end of the first plug rod is installed in the first positioning hole. Two second positioning holes are formed by a recess in one side of the pad, and one end of the second plug rod is installed in the second positioning hole.
[0014] Furthermore, the pointed end and the rod body are integrally formed, and the diameter of the rod body gradually increases in the direction away from the pointed end.
[0015] The beneficial effects of this utility model are:
[0016] The perforation on one side of the pad is designed to fit the tip of the tool. When not in use, the tip can be completely inserted into the perforation, forming a physical barrier to prevent direct exposure. Whether stored in a toolbox or temporarily stacked, the pad isolates the tip from contact with other metal parts and measuring instruments, preventing chipping, chipping, or deformation due to impacts. This ensures the tip's integrity, guaranteeing cutting efficiency during subsequent rotation into the soil, preventing slippage and positioning errors caused by tip damage, extending the tool's lifespan, and reducing tool replacement costs.

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0029] Please see Figures 1-4 This utility model provides a technical solution: a land management surveying point-finding device, including a pole 1, with a spiral blade 13 installed on the outer surface of the pole 1, a top plate 11 installed at one end of the pole 1, a connecting lug 12 installed at the middle of the side of the top plate 11 facing away from the pole 1, and a pointed tip 15 installed at the end of the pole 1 away from the top plate 11. The pointed tip 15 and the pole 1 are integrally formed, avoiding weak points in the connection caused by welding or assembly, improving the impact resistance of the pointed tip 15, and adapting to the rotation and soil entry requirements of hard soil layers; the diameter of the pole 1 gradually increases in the direction away from the pointed tip 15, which not only enhances the overall rigidity of the pole 1 and reduces bending deformation during rotation, but also works with the spiral blade 13 to better transmit downward pressure and improve soil entry efficiency; a straight rod or other tools are inserted into the connecting lug 12, making it easy to rotate the pole 1 using a straight rod, reducing the difficulty of applying force for the operator.
[0030] See Figures 1-4 The pad 2 has a through hole 25 on one side, and the pointed end 15 is inserted into the through hole 25. Two semi-threaded screws 21 are installed on the side of the pad 2 facing the top plate 11, which are symmetrically arranged about the rod body 1. Two round holes 14 are opened on the side of the top plate 11 facing the pad 2. The end of the semi-threaded screw 21 away from the pad 2 passes through the round hole 14. A limiting ring 24 is provided on the side of the round hole 14 facing the pad 2. The limiting ring 24 is sleeved on the semi-threaded screw 21 and connected and fixed to the semi-threaded screw 21. A nut 22 is provided on the side of the round hole 14 away from the limiting ring 24 and is threadedly connected to the semi-threaded screw 21. The pad 2 is connected to the top plate 11 by two symmetrical semi-threaded screws 21. After the semi-threaded screws 21 pass through the round hole 14 of the top plate 11, the limiting ring 24 can restrict the semi-threaded screws 21 from moving away from the pad 2. Then, the nut 22 is tightened to ensure that the pad 2 will not detach from the top plate 11 during transportation and handling. The pointed end 15 is always in the protective state within the perforation 25. Even in a bumpy field working environment, the connector can remain stable and will not fail due to vibration.
[0031] The perforation 25 on one side of the pad 2 is adapted to the tip 15 of the rod 1. When not in use, the tip 15 can be completely inserted into the perforation 25, forming a physical barrier through the pad 2 to prevent the tip 15 from being directly exposed. Whether stored in a toolbox or temporarily stacked, the pad 2 can isolate the tip 15 from contact with other metal parts and measuring instruments, preventing the tip 15 from chipping, rolling, or deforming due to impacts, thus ensuring the integrity of the tip 15. This ensures cutting efficiency during subsequent rotation into the soil, avoids slippage and positioning deviations caused by damage to the tip 15, extends the service life of the rod 1, and reduces tool replacement costs.
[0032] See Figures 1-4A first insertion rod 3 is installed in a first positioning hole formed by a recess in the middle of the side of the top plate 11 adjacent to the insertion ear 12. The first positioning hole provides a stable mounting base for the first insertion rod 3 and prevents the first insertion rod 3 from shaking under force. A first insertion hole 16 is formed by a recess on the side of the top plate 11 opposite to the first insertion rod 3. The first insertion rod 3 on one top plate 11 is inserted into the first insertion hole 16 on the other top plate 11. A second insertion rod 4 is installed in each of the two second positioning holes formed by a recess on one side of the pad block 2. The second positioning holes ensure that the second insertion rod 4 is installed firmly. Two second insertion holes are provided on the side of the pad block 2 opposite to the second insertion rod 4. Hole 26, a second insertion rod 4 on one pad 2 is inserted into a second insertion hole 26 on another pad 2. A first blocking ring 31 is fitted on the first insertion rod 3 and fixed to the first insertion rod 3. The outer diameter of the first blocking ring 31 is larger than the inner diameter of the first insertion hole 16. A second blocking ring 41 is fitted on the second insertion rod 4 and fixed to the second insertion rod 4. The outer diameter of the second blocking ring 41 is larger than the inner diameter of the second insertion hole 26. The first blocking ring 31 and the second blocking ring 41 can limit the insertion depth and prevent the first insertion rod 3 from being over-inserted into the first insertion hole 16 and the second insertion rod 4 from being over-inserted into the second insertion hole 26, so as to avoid damage to the components. The first plug rod 3 has a first conical head 32 installed at the end away from the top plate 11. The first conical head 32 and the first plug rod 3 are integrally formed. The second plug rod 4 has a second conical head 42 installed at the end away from the pad block 2. The second conical head 42 and the second plug rod 4 are integrally formed. The first conical head 32 and the second conical head 42 can guide the plug alignment, and the splicing of multiple positioning devices can be completed quickly without repeated adjustments.
[0033] By adapting the first insertion rod 3 of the top plate 11 to the first insertion hole 16 of another top plate 11, and the second insertion rod 4 of the pad 2 to the second insertion hole 26 of another pad 2, multiple rods 1 can be neatly stacked, allowing multiple positioning devices to be arranged in an orderly manner, avoiding the waste of space caused by scattered stacking. Especially when carrying a large number of positioning devices in field operations, the overall structure after splicing is easier to put into a storage box or fix on the work vehicle, reducing shaking and collision during transportation and reducing the risk of damage to the pointed tip 15.
[0034] See Figure 2 and Figure 3 The pad 2 has two recesses 23 formed on the side opposite to the semi-threaded screw 21. The second insertion hole 26 communicates with the recesses 23. A support sleeve 5 is installed on the inner wall of one of the recesses 23, which is concentrically arranged with the second insertion hole 26. A rubber sleeve 51 is glued inside the support sleeve 5 and wraps around the second insertion rod 4. The support sleeve 5 provides installation support for the rubber sleeve 51. The rubber sleeve 51 is elastic and wraps around the second insertion rod 4 to enhance the friction after insertion, preventing the assembled positioning devices from loosening and separating during transportation or storage, and further improving the stability of multiple positioning devices after splicing.
