Description

Technical Field

[0001] This utility model relates to the field of land planning equipment technology, specifically a land boundary demarcation device. Background Technology

[0002] In the process of urban and rural planning, it is necessary to mark the development projects and boundaries of undeveloped areas. Land needs to be marked with demarcation markers to determine the land boundaries, which is convenient for surveying or construction. Generally, bamboo poles or steel pipes are inserted directly into the ground, and colored flags are placed on top of the markers so that people can observe the specific location of the markers from a distance. However, the area around the planned land is generally open and prone to strong air currents. The colored flags are easily blown by the air currents, causing the demarcation markers to tilt to one side or fall down, which affects the accuracy of land boundary surveying in land planning.

[0003] Announcement No. CN220912309U discloses a boundary demarcation marker for land planning, comprising a first marker and a second marker slidably connected to the inner surface of the first marker. In this invention, during use, by aligning the first marker perpendicular to the ground and stepping on pedals on both sides of a first drill bit, the drill bit is easily driven into the ground, providing initial fixation of the marker. Holding and pushing any of the first connecting blocks moves the corresponding first mounting blocks onto the first marker, allowing the bottoms of multiple threaded rods to contact the ground. Then, using a tool, the first fixing blocks are rotated sequentially, causing the corresponding threaded rods to move downwards and drill into the ground. The multiple threaded rods, working in conjunction with the first drill bit, support the planning marker, preventing it from being blown over by strong outdoor air currents, thus improving the accuracy of land boundary mapping and enhancing land planning accuracy. Furthermore, existing boundary demarcation devices have the following drawbacks in use:

[0004] (1) The existing boundary demarcation device requires the use of tools to rotate the first fixed block in sequence so that the corresponding threaded rod moves down and drills into the ground. The multiple threaded rods penetrate into the ground and cooperate with the first drill bit to support the planning marker. The operation is relatively complicated and requires a certain amount of time and manpower, which greatly increases the workload of the staff and reduces the installation efficiency.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0006] The technical problem to be solved by this utility model is to overcome the above-mentioned technical defects and provide a boundary demarcation device.

[0007] To solve the above problems, the technical solution of this utility model is as follows: it includes a ground insertion structure, a pushing structure and a fixing structure. The pushing structure is inserted inside the ground insertion structure. An adjustment structure is provided on one side of the top of the pushing structure. A second marker is inserted into the top of the pushing structure. A rotating structure is provided on the top of the second marker.

[0008] The ground-insertion structure includes a first marker, a drill bit, and a foot pedal. The drill bit is fixedly connected to the bottom of the first marker. The first marker has a cavity inside. The front and rear sides of the cavity are respectively provided with a sliding groove. The center of each side of the first marker has a through hole. The top and sides of the first marker are fixedly connected with foot pedals. The top and bottom of the two through holes are respectively provided with a sliding groove. The interior of each of the two through holes is provided with two sets of fixing structures.

[0009] Furthermore, push rods are fixedly connected to both sides of the outer wall of the rotating disk, the inside of the moving block is provided with threaded holes, the bottom outer wall of the rotating rod is fitted with threads, and the shape of the moving block is a boss that is wider at the top and narrower at the bottom.

[0010] Furthermore, each set of fixed structures includes a connecting rod, a second drill bit, a pushing block, and a telescopic rod. One end of the connecting rod is fixedly connected to the second drill bit, and the other end passes through a through hole and is fixedly connected to the pushing block. The top and bottom of the connecting rod are respectively fixedly connected to the second slider, and the two second sliders are respectively provided with telescopic rods on the side away from the pushing block.

[0011] Furthermore, the shape of the pushing block is a right triangle, and the hypotenuse of the pushing block is parallel to the hypotenuse of the moving block.

[0012] Furthermore, the pushing structure includes a rotating rod, a moving block, and a rotating disk. One end of the rotating rod is connected to the inner wall of the cavity by a bearing, and the other end passes through the first marker rod and is sleeved with the rotating disk. The moving block is sleeved on the outer wall of the rotating rod.

[0013] Furthermore, the thread is threaded to the threaded hole, and the top front and rear sides of the movable block are respectively fixedly connected to slider one, and the two sliders one are respectively adapted to and connected to the slide groove one.

[0014] Furthermore, the two sliders are respectively adapted and connected to the slide groove, one end of each of the two telescopic rods is fixedly connected to the inner wall of the slide groove, and the other end is fixedly connected to the slider, and springs are respectively sleeved on the outer walls of the two telescopic rods.

[0015] The advantages of this invention compared to existing technologies are as follows:

[0016] 1. This utility model provides a boundary demarcation device. A pushing structure drives two sets of fixed structures to move laterally simultaneously. First, the push rod is held to keep the drill bit one perpendicular to the ground. Then, by stepping on the corresponding pedal, the drill bit one can be initially fixed deep into the ground. Next, rotating the push rod drives the rotating disk to rotate, which in turn drives the rotating rod to rotate, causing the moving block to move downwards. Since the inclined side of the moving block is parallel to the inclined side of the push block, the two push blocks move in opposite directions. The two push blocks, through a connecting rod, drive the drill bit two to move laterally away, thus deeply penetrating the ground. This increases the pull-out resistance of this utility model, ensuring its stability. The structure is simple, the operation is convenient, reduces the workload of maintenance personnel, and increases installation efficiency. Attached Figure Description

[0026] Example 2:

[0027] The following describes the scheme in Embodiment 1 in more detail with reference to the specific working method: The pushing structure 2 includes a rotating rod 201, a moving block 202 and a rotating disk 203. One end of the rotating rod 201 is connected to the inner wall of the cavity 102 by a bearing, and the other end passes through the first marker rod 101 and is sleeved with the rotating disk 203. The moving block 202 is sleeved on the outer wall of the rotating rod 201. Push rods 204 are fixedly connected to both sides of the outer wall of the rotating disk 203. The moving block 202 has a threaded hole 206 inside. The bottom outer wall of the rotating rod 201 is sleeved with a thread 205.

[0028] Example 3:

[0029] The following describes the solution in Embodiment 2 in more detail with reference to the specific working method. Each fixed structure 3 includes a connecting rod 301, a second drill bit 302, a push block 303, and a telescopic rod 305. One end of the connecting rod 301 is fixedly connected to the second drill bit 302, and the other end passes through the through hole 105 and is fixedly connected to the push block 303. The top and bottom of the connecting rod 301 are respectively fixedly connected to the second slider 304, and the two second sliders 304 are respectively provided with the telescopic rod 305 on the side away from the push block 303.

[0030] Example 4:

Then, by stepping on the corresponding foot pedal 107, the drill bit 104 can be initially fixed deep into the ground. Then, the push rod 204 is rotated to drive the rotating disk 203 to rotate. The rotating disk 203 drives the rotating rod 201 to rotate, causing the moving block 202 to move downward. Since the inclined side of the moving block 202 is parallel to the inclined side of the push block 303, the two push blocks 303 are driven to move in opposite directions. The two push blocks 303 drive the drill bit 302 to move laterally away through the connecting rod 301, thus deeply inserting it into the ground. This increases the tensile strength of the present invention, ensures the stability of the fixed structure, has a simple structure, is easy to operate, reduces the workload of maintenance personnel, and increases installation efficiency.
