Description

Technical Field

[0001] The utility model relates to the field of surveying and mapping auxiliary tools, in particular to a marking device which is convenient for fixing in surveying and mapping engineering. Background Art

[0002] When conducting engineering surveying and mapping operations, in order to clearly mark a specific location, the operator will generally erect a sign at the location to facilitate observation and determine the location distance. The prior art generally requires the operator to directly insert the sign into the designated location. However, when inserting the sign, it is difficult for the operator to judge the underground situation. Directly inserting the sign with force can easily cause the bottom of the sign to collide strongly with a hard object, causing damage, and also causing damage to the operator's hands. At the same time, when the height of the sign itself is not enough, it is necessary to use straps and other items to extend the height, which makes the operation and use very cumbersome.

[0003] Therefore, in response to the above problems, a marking device that is convenient for fixing in surveying and mapping projects is now developed. Utility Model Content

[0004] In order to overcome the shortcomings of the existing device, that it is difficult for operators to judge the underground situation during actual use, and that direct and forceful insertion may easily cause the bottom end of the mark to collide strongly with hard objects, thereby causing damage, and may also cause damage to the operator's hands, and at the same time, when the height of the mark itself is not enough, it is necessary to use straps and other items to extend the height, which makes the operation and use very cumbersome. The utility model provides a marking device that is easy to fix in surveying and mapping projects.

[0005] The technical solution of the utility model is: a marking device which is easy to fix in surveying and mapping projects, comprising a benchmark, a plug rod is slidably arranged inside the benchmark, an adjusting piece is rotatably arranged on the upper part of the benchmark, the adjusting piece is threadedly connected to the plug rod, a first fixing ring is connected to the lower part of the benchmark, three rotating plates are rotatably arranged on the first fixing ring, contact plates are slidably connected to the rotating plates, and a clamping mechanism is provided on the upper part of the benchmark.

[0006] As a preferred technical solution of the utility model, the clamping mechanism includes a mounting frame, the mounting frame is connected to the upper part of the pole, two clamping members are slidably provided on the mounting frame, and a first spring is connected between the clamping members and the mounting frame.

[0007] As a preferred technical solution of the utility model, it also includes a fixing mechanism, which includes a second fixing ring, the middle part of the benchmark is connected to the second fixing ring, the lower part of the second fixing ring is connected to a second spring, the second spring is sleeved on the benchmark, the bottom end of the second spring is connected to a press plate, and the press plate is slidably connected to the benchmark.

[0008] As a preferred technical solution of the utility model, the bottom of the insertion rod is a conical structure.

[0009] As a preferred technical solution of the utility model, the adjusting member is provided with a power-assisting groove.

[0010] As a preferred technical solution of the utility model, the inner side of the clamping member is a curved surface structure.

[0011] By adopting the above technical solution, the beneficial effects of the utility model are:

[0012] After the rod is inserted into the ground, the utility model relies on rotating the adjustment part to make the rod slowly penetrate into the ground. In this process, it can prevent the rod from directly contacting with hard objects and causing damage to the end. At the same time, after the insertion of the benchmark is completed, it can be immediately deployed and reinforced to improve the stability of the benchmark. When the height needs to be extended, it can also be operated quickly. The overall use is very convenient and efficient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments, but is not intended to limit the present invention. Example

[0020] A marking device that is easy to fix in surveying and mapping projects, such as Figure 1-Figure 3As shown, it includes a benchmark 1, a plug rod 2 for inserting into the ground for fixing is slidably arranged inside the benchmark 1, the bottom of the plug rod 2 is a conical structure, an adjusting member 3 is rotatably arranged on the upper part of the benchmark 1, the adjusting member 3 has a power-assisting groove, the adjusting member 3 is threadedly connected to the plug rod 2, a first fixing ring 4 is connected to the lower part of the benchmark 1, three rotating plates 5 are rotatably arranged on the first fixing ring 4, and contact plates 6 for adapting to the terrain to improve the supporting strength are slidably connected to the rotating plates 5, and a clamping mechanism 7 for extending the height is provided on the upper part of the benchmark 1.

[0021] like Figure 1 and Figure 4 As shown, the clamping mechanism 7 includes a mounting frame 71, the mounting frame 71 is connected to the upper part of the benchmark 1, two clamping members 72 are slidably arranged on the mounting frame 71, the inner sides of the clamping members 72 are both arc-shaped structures, and a first spring 73 is connected between the clamping members 72 and the mounting frame 71.

[0022] It should be noted that when conducting engineering surveying and mapping operations, in order to clearly mark a specific location, the operator will generally erect a sign at the location to facilitate observation and determine the location distance. Unlike the prior art of directly inserting the sign into the ground, during use of the device, it is necessary to first insert the insertion rod 2 into the ground. At this time, the adjustment member 3 is rotated to make the insertion rod 2 start to slide downward along the benchmark 1, so that the insertion rod 2 can be inserted deeper, thereby improving the stability of the benchmark 1 after insertion. As the insertion is completed, the rotating plates 5 are flipped outward and unfolded, and then the contact plates 6 are pulled outward and unfolded to support and reinforce the lower part of the benchmark 1, thereby further improving the stability of the benchmark 1. After that, the flag or other mark is inserted into the mounting frame 71 and fixed by the cooperation between the clamping member 72 and the first spring 73, so as to achieve the effect of extending the height of the benchmark 1, making observation more direct and convenient. Example

[0023] On the basis of Example 1, Figure 1 and Figure 5 As shown, it also includes a fixing mechanism 8, which includes a second fixing ring 81. The middle part of the benchmark 1 is connected to the second fixing ring 81, and the lower part of the second fixing ring 81 is connected to a second spring 83. The second spring 83 is sleeved on the benchmark 1, and the bottom end of the second spring 83 is connected to a press plate 82 for pressing and limiting the rotating plate 5, and the press plate 82 is slidably connected to the benchmark 1.

[0024] It should be noted that, under normal conditions, in order to prevent the rotating plate 5 from accidentally flipping downward and unfolding, the rotating plate 5 can be kept pressed and limited by the cooperation between the pressing plate 82 and the second spring 83. When the rotating plate 5 needs to be flipped, the pressing plate 82 is pulled upward along the benchmark 1 so that the rotating plate 5 is no longer limited. Similarly, when the rotating plate 5 is flipped and reset, the pressing plate 82 also needs to be pulled upward to reserve sufficient reset distance for the rotating plate 5.

[0025] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
