[0002] Civil engineering is a general term for the science and technology of constructing various engineering facilities. It includes not only the materials and equipment used, and the technical activities such as surveying, design, construction, maintenance, and repair, but also the objects of engineering construction, namely, various engineering facilities built on or under the ground, on land or in water, directly or indirectly serving human life, production, military, and scientific research. In civil engineering, a surveying tool is used, which is a device used to measure, detect, and analyze specific areas or targets.

[0003] However, traditional surveying tools are simply mounted on supports without any protective measures. Some supports are not installed securely or are subjected to external impacts, which can cause the supports to shake and tip over, thereby damaging the surveying tools. Furthermore, surveying tools are susceptible to damage from the external environment. During operation, dust, rainwater, and other contaminants can enter the surveying tools and affect their performance.

[0004] Therefore, it is necessary to provide a new surveying tool to solve the above-mentioned technical problems. Utility Model Content

[0005] The technical problem solved by this utility model is to provide a surveying tool that is easy to use, can protect and stably support the tool, and whose height can be easily adjusted according to the needs of the measurement task.

[0006] To solve the above-mentioned technical problems, the surveying tool provided by this utility model includes: a base, two dustproof plates on the top of the base, a threaded tube rotatably installed inside the base, one end of the threaded tube extending outside the base, a screw inside the threaded tube, a lifting plate on the top of the base, one end of the screw extending outside the surveying instrument and fixedly connected to the lifting plate, the threaded tube being threadedly connected to the screw, a rotating disk rotatably installed on the top of the lifting plate, a surveying instrument on the top of the rotating disk, a connecting rod rotatably installed inside the base, a first bevel gear fixedly installed at one end of the connecting rod, a second bevel gear fixedly installed on the outside of the threaded tube, the first bevel gear meshing with the second bevel gear, and a knob fixedly installed at the other end of the connecting rod extending outside the base.

[0007] Preferably, a support platform is fixedly installed at the bottom of the base. The bottom of the support platform is provided with three adjusting sleeves, each of which has a supporting foot tube. The bottom end of the supporting foot tube extends outside the adjusting sleeve. An adjusting cylinder is fixedly installed at the bottom of the support platform. A supporting column is provided inside the adjusting cylinder. The bottom end of the supporting column extends outside the adjusting cylinder and is fixedly installed with a supporting base. A second connecting seat is fixedly installed on the side of the supporting foot tube and the supporting column that are close to each other. One end of a first supporting rod and one end of a second supporting rod are respectively hinged to the two second connecting seats. The other end of the first supporting rod is rotatably installed on the other end of the second supporting rod.

[0008] Preferably, two guide plates are fixedly installed on the top of the base, and the lifting plate is slidably installed on the two guide plates.

[0009] Preferably, the two dustproof plates are rotatably mounted with hinges between them and the base, and the top of the dustproof plates is fixedly mounted with a fixing buckle.

[0010] Preferably, both the support leg tube and the adjusting sleeve are provided with multiple fixing holes, and the fixing holes on the support leg tube and the adjusting sleeve are connected to each other, with fixing bolts provided in the fixing holes.

[0013] Compared with related technologies, the surveying tool provided by this utility model has the following beneficial effects:

[0014] This utility model provides a surveying tool. Through the cooperation of dustproof plates, fixing buckles, hinges, and a base, the two dustproof plates, when closed, not only prevent damage to the tool due to collisions but also effectively block dust from entering the interior of the surveying tool, preventing blockage of precision components, affecting mechanical movement, or interfering with the normal operation of electronic components. Through the cooperation of a knob, connecting rod, first bevel gear, screw, second bevel gear, threaded tube, lifting plate, and rotating disk, the operator can adjust the height of the surveying tool vertically while turning the knob, thereby meeting the height requirements in different measurement scenarios. Furthermore, the rotating disk allows for observation from different angles. The tool provides a wider field of view, offering more data and information for surveying work. Furthermore, during use, the tool can be raised or lowered outside the dust cover, allowing surveying to continue without opening the dust cover. Through the coordinated operation of the first connecting seat, fixing bolt, first support rod, adjusting sleeve, support leg tube, fixing hole, second support rod, second connecting seat, support base, adjusting cylinder, and support column, when the adjusting sleeve and support leg tube are opened, the first and second support rods form additional support between the support leg tube and the support column, making the entire structure more stable, effectively reducing the swaying of the support leg tube, increasing its anti-tipping capacity, lowering the risk of the support leg tube tipping over, and preventing damage to the surveying tool.

[0028] The working principle of the surveying tool provided by this utility model is as follows:

[0029] First, when a survey is needed, remove the fixing bolt 11, allowing the support leg tubes 9 and support columns 17 to extend beyond the adjusting sleeve rod 6 and adjusting cylinder 10, respectively. As the three support leg tubes 9 are extended outward, the first support rod 16 and the second support rod 26 unfold, forming additional support between the three support leg tubes 9. Then, insert the fixing bolt 11 into the fixing hole 7 to fix the support leg tubes 9. Open the two dustproof plates 2, and the survey can be carried out. When the height needs to be adjusted, turn the knob 13 to rotate the connecting rod 21, which in turn drives the threaded tube 19 to rotate through the cooperation of the first bevel gear 22 and the second bevel gear 27. When the threaded tube 19 rotates, the screw 24 rises. When the height is adjusted, you can stop turning the knob 13. Alternatively, without opening the two dustproof plates 2, you can continue to turn the knob 13 to extend the surveying instrument 23 beyond the dustproof plates 2, and the survey can also be carried out.

[0030] Compared with related technologies, the surveying tool provided by this utility model has the following beneficial effects:

[0031] This utility model provides a surveying tool. Through the cooperation of dustproof plates 2, fixing buckles 1, hinges 3, and a base 4, the two dustproof plates 2, when closed, not only prevent damage to the tool due to collisions but also effectively block dust from entering the surveying tool's interior, preventing blockage of precision components, affecting mechanical movement, or interfering with the normal operation of electronic components. Through the cooperation of knob 13, connecting rod 21, first bevel gear 22, screw 24, second bevel gear 27, threaded tube 19, lifting plate 15, and rotating disk 20, the operator can adjust the surveying tool's height vertically by rotating knob 13, thereby meeting the height requirements of different measurement scenarios. Furthermore, the rotating disk 20 allows for observation of different angles. This provides more data and information for surveying work. In addition, when using the tool, it can be raised and lowered outside the dustproof plate 2, and the survey can continue without opening the dustproof plate 2.
