It plays a fundamental role in urban and rural construction planning, land and resources utilization, environmental protection and other work, and provides preliminary and basic services for various development and construction projects.

[0004] After surveying the construction area, the corresponding base points need to be marked. In current construction practices, a steel bar or an object is usually inserted for marking. However, in actual use, the marks may deviate from their original positions.

[0005] Therefore, this application proposes a positioning pin for coordinate marking. Utility Model Content

[0006] This application proposes a positioning pin for coordinate marking to solve the problems mentioned in the background art. By opening two anti-dislodgement holes on the insertion rod and staggering them into a cross shape, the positioning pin can be further stably positioned, thus playing a stabilizing role. By setting an insertion block on the cap and inserting the insertion block into the ground, the position of the cap can be accurately positioned to prevent the cap from moving and causing the insertion rod to shift during positioning. This improves the positioning effect and greatly enhances the practicality of the device, ensuring that the pin does not deviate from the original marking position during actual use.

[0007] To achieve the above objectives, this application adopts the following technical solution:

[0008] A positioning pin for coordinate marking includes a rod, a cap, and a handle. The rod has two anti-dislodgement holes inside. The cap has multiple insert blocks fixedly connected to its outside. The rod and the cap are slidably connected. The rod and the handle are threadedly connected. The handle has a positioning cross.

[0009] As a preferred embodiment, the two anti-detachment holes are designed in an alternating pattern, forming a cross shape when viewed from above;

[0010] By creating two anti-dislodgement holes on the insertion rod, arranged in an interlaced cross shape, the positioning pin can be further stabilized, thus enhancing the practicality of the device.

[0011] In a preferred embodiment, the insertion rod is provided with a first thread, and the handle is provided with a second thread inside, and the insertion rod is threadedly connected to the handle through the first thread and the second thread;

[0012] The engagement between the first and second threads allows the handle to be fixed to the insert rod, enabling a quick connection between the insert rod, cap, and handle, thereby improving the practicality of the device.

[0013] In a preferred embodiment, the cap has a through hole inside, and the through hole has multiple slots inside;

[0014] By placing the cap on the insertion rod, the stop block is positioned in the groove, and the locking block is positioned in the slot, thus achieving initial docking between the insertion rod and the cap, thereby improving the practicality of the device.

[0015] In a preferred embodiment, a plurality of locking blocks are fixedly connected to the insertion rod, and each locking block is located inside a slot;

[0016] By sliding the insert rod off the cap, the stop block disengages from the groove, and the locking block disengages from the slot, thus enabling quick disassembly of the insert rod and the cap, thereby improving the practicality of the device.

[0017] In a preferred embodiment, a groove is provided inside the through hole, and a stop block is fixedly connected to the insert rod on the side of the locking block away from the first thread, and the stop block is located inside the groove;

[0018] By incorporating through holes, grooves, slots, blocks, locking blocks, first threads, handles, positioning crosses, and second threads, a detachable connection between the insertion rod and the cap can be achieved for subsequent use, thereby enhancing the practicality of the device.

[0019] The beneficial effects of this application are:

[0020] 1. This type of coordinate marking positioning pin, by opening two anti-dislodgement holes on the insertion rod, with an interlaced cross-shaped design, can further stabilize the positioning pin and play a solid role. By setting an insertion block on the cap and inserting the insertion block into the ground, the position of the cap can be accurately positioned to prevent the cap from moving and causing the insertion rod to shift during positioning. This improves the positioning effect and greatly enhances the practicality of the device, ensuring that the pin will not deviate from the original marking position during actual use.

[0021] 2. This type of coordinate marking positioning pin, by setting through holes, grooves, slots, stops, locking blocks, first threads, handles, positioning crosses, and second threads, enables a detachable connection between the insertion rod and the cap for subsequent use. During installation, after the insertion rod is positioned, the cap is immediately placed on the insertion rod, so that the stop is located in the groove and the locking block is located in the slot, achieving initial docking between the insertion rod and the cap. Then, the handle is placed on the top of the insertion rod, and then the tool is used to rotate the handle through the positioning cross. The engagement between the first and second threads fixes the handle to the insertion rod, thereby achieving a quick connection between the insertion rod, the cap, and the handle, greatly improving the practicality of the device.

[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0028] Reference Figure 1-4A positioning pin for coordinate marking includes a rod 1, a cap 2, and a handle 3. The rod 1 has two anti-dislodgement holes 11 inside. The cap 2 has multiple insert blocks 22 fixedly connected to the outside. The rod 1 and the cap 2 are slidably connected. The rod 1 and the handle 3 are threadedly connected. The handle 3 has a positioning cross 31.

[0029] Reference Figure 1-4 The two anti-disengagement holes 11 are staggered and appear as a cross when viewed from above. By opening two anti-disengagement holes 11 on the insertion rod 1, the staggered design forms a cross shape, which can further stabilize the positioning nail and play a solid role, thereby improving the practicality of the device.

[0030] Reference Figure 1-4 The insertion rod 1 is provided with a first thread 14, and the handle 3 is provided with a second thread 32. The insertion rod 1 is threadedly connected to the handle 3 through the first thread 14 and the second thread 32. Through the cooperation between the first thread 14 and the second thread 32, the handle 3 is fixed on the insertion rod 1, realizing the quick connection between the insertion rod 1, the cap 2 and the handle 3, thereby improving the practicality of the device.

[0031] Reference Figure 1-4 The cap 2 has a through hole 21 inside, and multiple slots 212 inside the through hole 21. By putting the cap 2 on the rod 1, the stop block 12 is located in the groove 211 and the locking block 13 is located in the slot 212, the initial docking between the rod 1 and the cap 2 is achieved, thereby improving the practicality of the device.

[0032] Reference Figure 1-4 Multiple locking blocks 13 are fixedly connected to the insertion rod 1, and each locking block 13 is located inside the locking groove 212. By sliding the insertion rod 1 off the cap 2, the stop block 12 is disengaged from the groove 211, and the locking block 13 is disengaged from the locking groove 212. Thus, the insertion rod 1 and the cap 2 can be quickly disassembled, thereby improving the practicality of the device.

[0033] Reference Figure 1-4 The through hole 21 has a groove 211 inside. A stop block 12 is fixedly connected to the insertion rod 1 on the side of the locking block 13 away from the first thread 14, and the stop block 12 is located inside the groove 211. By setting the through hole 21, groove 211, locking groove 212, stop block 12, locking block 13, first thread 14, handle 3, positioning cross 31 and second thread 32, a detachable connection between the insertion rod 1 and the cap 2 can be realized for subsequent use, thereby improving the practicality of the device.

[0034] Working principle: During use, the insertion rod 1 needs to be inserted into the ground. This involves digging a pit, pouring cement into the pit to fix a steel bar, and inserting the steel bar into the anti-disengagement hole 11 to secure the insertion rod 1. Combined with the cap 2, this secures the positioning pin and ensures its stability. Two anti-disengagement holes 11, staggered in a cross shape, further stabilize the positioning pin, providing a secure fit. An insertion block 22 on the cap 2, inserted into the ground, accurately positions the cap 2, preventing displacement of the insertion rod 1 during positioning and ensuring it stays in its original marked position, thus improving the positioning effect. The system incorporates a through hole 21, groove 211, slot 212, stop 12, locking block 13, first thread 14, handle 3, positioning cross 31, and second thread 32. The insertion rod 1 and the cap 2 are detachably connected for easy use. Using a tool, the handle 3 can be rotated through the positioning cross 31. The engagement between the second thread 32 and the first thread 14 allows the handle 3 to be removed from the insertion rod 1. Then, the insertion rod 1 is slid off the cap 2, causing the stop block 12 to disengage from the groove 211 and the locking block 13 to disengage from the slot 212. This allows for quick disassembly of the insertion rod 1 and the cap 2. Similarly, during installation, after the insertion rod 1 is positioned, the cap 2 is immediately placed on the insertion rod 1, so that the stop block 12 is located in the groove 211 and the locking block 13 is located in the slot 212, achieving initial connection between the insertion rod 1 and the cap 2. Then, the handle 3 is placed on the top of the insertion rod 1. Subsequently, using a tool, the handle 3 is rotated through the positioning cross 31. The engagement between the first thread 14 and the second thread 32 fixes the handle 3 on the insertion rod 1, thus achieving a quick connection between the insertion rod 1, the cap 2, and the handle 3.

[0035] The above are merely preferred embodiments of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and the inventive concept of this application, should be included within the scope of protection of this application.
