Description

Technical Field

[0001] This utility model relates to the field of processing technology, specifically to a benchmark for engineering measurement. Background Technology

[0002] In various engineering construction, topographic mapping, and geological exploration fields, engineering surveying poles are an indispensable basic tool. Their main function is to provide stable, vertical benchmarks for surveying instruments or serve as temporary aiming targets. Traditional surveying poles are typically simple in structure, often consisting of a single, independent pole, requiring manual alignment or support via a simple tripod. However, existing surveying poles and their support structures have several shortcomings. First, while common tripods offer some stability, their leg length and angle adjustments are often inflexible, and they are not easy to store, affecting transportation and carrying. Second, when measuring on soft ground, the surveying pole cannot be stably fixed to the ground, resulting in poor stability and susceptibility to tilting due to external forces (such as wind or minor impacts). Therefore, there is an urgent need for a new type of engineering surveying pole that can be quickly deployed and stored, and ensures excellent stability even on soft soil. Utility Model Content

[0003] The purpose of this invention is to provide a benchmark for engineering surveying to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an engineering surveying marker, comprising a support rod, a support base fixedly mounted on the top surface of the support rod, three first mounting seats symmetrically mounted on the outer surface of the support base, an adjusting rod rotatably connected to the three first mounting seats via a rotating shaft, a second mounting seat welded to one side of the outer surface of the adjusting rod, a collar slidably fitted on the outer surface of the support rod, three third mounting seats symmetrically welded to the outer surface of the collar, a connecting rod rotatably connected to the three third mounting seats via a rotating shaft, the other end of the connecting rod rotatably connected to the second mounting seat via a rotating shaft, a telescopic leg slidably mounted in the inner cavity of the adjusting rod, a threaded wire provided at the bottom end of the inner cavity of the telescopic leg, a connecting head provided at the bottom of the telescopic leg, a first threaded post welded to one end of the connecting head, the first threaded post being threadedly connected to the telescopic leg, a second threaded post welded to the other end of the connecting head, and a soil-drilling steel needle welded to the bottom surface of the second threaded post.

[0005] Preferably, the outer surface of the telescopic leg is provided with a plurality of first insertion holes, and a first threaded clamping rod is threadedly inserted into one of the first insertion holes and the adjusting rod.

[0006] Preferably, the first threaded post is threadedly connected to a threaded sleeve, and the other end of the threaded sleeve is fixedly connected to a flat pad foot sleeve by an insert rod. The flat pad foot sleeve is completely in contact with the ground, and the second threaded post is threadedly connected to the telescopic leg.

[0007] Preferably, the outer surface of the support rod is provided with a plurality of second insertion holes, one of which is connected to the collar by a second threaded clamping rod via a thread.

[0008] Preferably, a marker is mounted on the top surface of the support base, and a calibration surface is mounted on the top surface of the marker.

[0009] Preferably, the drilling steel needle can be accommodated in the inner cavity of the telescopic leg.

[0010] Compared with existing technologies, the beneficial effects of this utility model are: significantly enhanced stability and adaptability: by setting up a linkage telescopic support mechanism composed of support rods, collars, adjusting rods, connecting rods, etc., the synchronous and stable expansion and contraction of the three support points are achieved. This structure not only makes the target pole form a stable tripod structure when supported, effectively preventing tilting and swaying, but also improves the accuracy of measurement data; greatly improved portability and operational efficiency: this utility model adopts a foldable and telescopic integrated design. When not in use, the telescopic legs can be retracted into the adjusting rod, and the entire support mechanism can be folded up, greatly reducing the storage volume and transportation space, making it easy to carry to the field measurement site. During use, the support mechanism can be quickly extended and retracted by sliding the collar. The adjustment process is simple, quick, time-saving, and labor-saving, significantly improving the efficiency of engineering surveying. The grounding structure is optimized for wider applicability: the bottom of the telescopic leg adopts a detachable connector design and integrates a soil-drilling steel needle. On the one hand, the sharp soil-drilling steel needle can easily insert into soft ground, providing strong anchoring force; on the other hand, the soil-drilling steel needle is threaded to the telescopic leg through the second threaded post, allowing the soil-drilling steel needle to be stored inside the telescopic leg cavity. At this time, the threaded sleeve is connected to the first threaded post, and the flat pad foot sleeve is quickly connected to the threaded sleeve through the insertion rod, which allows for quick installation of the flat pad foot sleeve. Different flat pad foot sleeves can be replaced to suit different ground conditions such as hardened roads, greatly enhancing the versatility of this surveying pole. Attached Figure Description
