Description

Technical Field

[0001] The present application relates to the technical field of field surveying and mapping, and in particular to a surveying point marking device for field surveying and mapping. Background Art

[0002] Surveying and mapping refers to the measurement, collection and mapping of the shape, size, spatial position and attributes of natural geographical elements or artificial facilities on the surface. Surveying and mapping instruments are widely used in surveying and mapping, and surveying and mapping instruments need to be used in conjunction with surveying and mapping point markers in order to conduct accurate surveying and mapping.

[0003] The patent document with publication number CN220453283U in the prior art provides a fixed-point marking device for surveying and mapping. The device is equipped with components such as a rotating rod, a ratchet, a thorn and a rotating head. When the positioning cylinder is at the marking point, the ratchet is driven by rotating the handle clockwise, and the ratchet drives the rotating rod, and the rotating rod drives the marking rod to rotate. Since the ratchet is limited by the thorn and can only rotate counterclockwise, the marking rod can be gradually driven into the hard ground by repeatedly rotating the handle in a positive and negative direction. The overall structure facilitates the installation of the marking rod at the marking point.

[0004] Although the above-mentioned existing technical solutions can drive the marking rod into the hard ground through components such as a rotating rod, a ratchet, thorns and a rotating head, they still have the following defects: driving the marking rod into the ground requires physical strength and time, and the field surveying task is heavy. Such operation will reduce the surveying efficiency and thus prolong the surveying time.

[0005] In view of this, we propose a surveying point marking device for field surveying. Utility Model Content

[0006] 1. Technical problems to be solved

[0007] The purpose of the present application is to provide a surveying point marking device for field surveying to solve the problem of reducing surveying efficiency proposed in the above-mentioned background technology and realize efficient setting of marking points.

[0008] 2. Technical solution

[0012] By adopting the above technical solution, the triangular structure design of the bottom of the support frame can directly place the marking rod in various environmental scenes, and direct placement avoids unnecessary operations, thereby increasing the surveying and mapping efficiency. In addition, through the design of two rotating frames and the middle block, the support frame can be placed at will, so that the marking rod can be in a vertical state, which can further increase the surveying and mapping efficiency.

[0013] Preferably, the upper end of the support frame is slidably connected to a limiting member, and the limiting member includes a sliding frame slidably connected to the support frame.

[0014] Preferably, the limit member also includes a limit block slidably connected to the sliding frame, a positioning spring is connected and fixed to the limit block, the other end of the positioning spring is connected and fixed to the sliding frame, both ends of the top surface of the support frame are provided with limit grooves, the limit block is snap-fitted with the limit grooves, and the limit block is connected and fixed to another rotating frame.

[0015] By adopting the above technical solution and the design of the limiter, when the marking rod is not in use, the marking rod can be pulled, thereby indirectly driving the limit block to compress the positioning spring and slide down out of the limiting groove, so that the sliding frame can be driven to slide to the other end of the support frame, and the support frame can be easily taken away.

[0016] Preferably, a positioning frame is provided in the clearance outside the marking rod, and friction fixing parts are installed on the positioning frame and the supporting frame.

[0017] Preferably, the friction fixing part includes a connecting frame connected and fixed to the positioning frame and the supporting frame, two friction blocks are slidably connected inside the connecting frame, compression springs are connected and fixed inside the two friction blocks, and a connecting sliding frame is rotatably connected to the outside of the two connecting frames, and the friction blocks are frictionally matched with the connecting sliding frames.

[0018] By adopting the above technical solution, the friction fixing part cooperates with the design of the positioning frame, so as to limit the marking rod and make corresponding adjustments according to the position of the marking rod. When adjusting, it is only necessary to rotate the positioning frame. After adjustment, the compression spring will drive the friction block to rub against the connecting sliding frame. At this time, the positioning frame will be fixed and limited, so as to avoid the problem that the wind will blow the positioning frame and cause interference in surveying and mapping.

[0027] The present application is further described in detail below in conjunction with the accompanying drawings.

[0028] Embodiment 1:

[0029] Reference Figure 1 and Figure 2 , the embodiment of the present application discloses a surveying point marking device for field surveying. Support frame 1, the bottom of the support frame 1 is a triangular structure;

[0030] A marking rod 2, on which a conventional surveying and mapping scale is engraved;

[0031] The vertical member 3 includes a middle block 4 , and the middle block 4 is rotatably connected to two rotating frames 5 on the side, and one of the rotating frames 5 is connected and fixed to the end of the marking rod 2 .

[0032] The bottom of the support frame 1 is designed with a triangular structure, so the marking rod 2 can be directly placed in various environmental scenes. Direct placement avoids unnecessary operations and increases the surveying and mapping efficiency. Through the design of two rotating frames 5 and the middle block 4, the support frame 1 can be placed at will and the marking rod 2 can be in a vertical state, which can further increase the surveying and mapping efficiency.

[0033] Embodiment 2:

[0034] Reference Figure 2 The embodiment of the present application discloses a surveying point marking device for field surveying. The upper end of the support frame 1 is slidably connected to a limit member 6, and the limit member 6 includes a sliding frame 7 slidably connected to the support frame 1.

[0035] The limiting member 6 also includes a limiting block 8 that is slidably connected to the sliding frame 7. A positioning spring 9 is connected and fixed to the limiting block 8. The other end of the positioning spring 9 is connected and fixed to the sliding frame 7. Limiting grooves 10 are provided at both ends of the top surface of the support frame 1. The limiting block 8 is snap-fitted with the limiting grooves 10. The limiting block 8 is connected and fixed to another rotating frame 5.

[0036] The design of the limit member 6 allows the marking rod 2 to be pulled when the marking rod 2 is not in use, thereby indirectly driving the limit block 8 to compress the positioning spring 9 and slide down out of the limit groove 10, so that the slide frame 7 can be driven to slide to the other end of the support frame 1, and the support frame 1 can be easily taken away.

[0037] Embodiment three:

[0038] Reference Figure 3 The embodiment of the present application discloses a surveying point marking device for field surveying. A positioning frame 11 is provided in the clearance outside the marking rod 2, and a friction fixing member 12 is installed on the positioning frame 11 and the support frame 1.

[0039] The friction fixing member 12 includes a connecting frame 13 connected and fixed to the positioning frame 11 and the support frame 1. Two friction blocks 14 are slidably connected inside the connecting frame 13. The two friction blocks 14 are internally connected and fixed with compression springs 16. The two connecting frames 13 are rotatably connected to the outside with a connecting sliding frame 15. The friction blocks 14 and the connecting sliding frame 15 are frictionally matched.

[0040] The friction fixing part 12 cooperates with the design of the positioning frame 11 to limit the marking rod 2 and can be adjusted accordingly according to the position of the marking rod 2. When adjusting, it is only necessary to rotate the positioning frame 11. After adjustment, the compression spring 16 will drive the friction block 14 to frictionally press the connecting sliding frame 15. At this time, the positioning frame 11 will be fixed and limited to avoid the problem of wind blowing the positioning frame 11 and causing interference in surveying and mapping.

[0041] The implementation principle of a surveying point marking device for field surveying and mapping in an embodiment of the present application is as follows: during surveying and mapping, the marker rod 2 is directly placed in various environmental scenes to avoid unnecessary operations. The two rotating frames 5 cooperate with the middle block 4, so that the support frame 1 can be placed at will, and the marker rod 2 can be in a vertical state. When the marker rod 2 is not in use, the marker rod 2 is pulled, thereby indirectly driving the limit block 8 to compress the positioning spring 9 and slide down out of the limit groove 10, so that the slide frame 7 can be driven to slide to the other end of the support frame 1, and the support frame 1 can be conveniently taken. The friction fixing part 12 cooperates with the positioning frame 11 to limit the marker rod 2, and can be adjusted accordingly according to the position of the marker rod 2. When adjusting, the positioning frame 11 is rotated and adjusted. After adjustment, the compression spring 16 will drive the friction block 14 to rub against the connected slide frame 15. At this time, the positioning frame 11 will be fixed and limited to prevent wind from blowing the positioning frame 11 and causing surveying and mapping interference.
