Description

Technical Field

[0001] This utility model relates to the field of measuring benchmark technology, and in particular to a retractable engineering measuring benchmark. Background Technology

[0002] Engineering surveying refers to a series of surveying activities performed at various stages of an engineering project, including surveying, design, construction, and management. It directly serves all aspects of a construction project, including surveying, design, construction, installation, final acceptance, monitoring, and operation management. The primary function of a surveying benchmark is to serve as an indicator of surveying points. In practice, a combination of a level and a surveying benchmark is often used. The specific steps include: placing the benchmark at an appropriate location on the construction site; then, from the leveling instrument's position, precisely observing the benchmark through the leveling instrument's objective lens to measure key data such as the elevation difference between the leveling instrument's position and the benchmark. This method is widely used in the field of building engineering surveying, aiming to help construction workers complete their work efficiently, ensure the accuracy of measurement positioning, and thus improve project quality and work efficiency.

[0003] Chinese utility model patent CN217276207U discloses an engineering measurement benchmark for more accurate measurement. Its technical background states that "Currently, in measurement, the benchmark is often held manually, relying on the operator's feel to ensure the correct angle, which easily leads to the following problems:"

[0004] 1. Due to the complexity of the terrain, it is difficult to keep the markers and the horizontal plane vertical, which leads to inaccurate measurements and makes it impossible to guarantee the quality of construction.

[0005] 2. During use, since the marker is often held manually, the operator may not easily notice the tilt of the marker after a long period of time, which can easily lead to errors in measurement and compromise the quality of construction.

[0006] As can be seen from the aforementioned publicly available documents, in actual engineering surveying operations, the ground on which the existing markers are located is not flat. When the markers are erected on the ground, they cannot be guaranteed to be vertical, which will seriously affect the accuracy of engineering surveying.

[0007] To address this, a scalable engineering measurement benchmark is proposed. Utility Model Content

[0025] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0026] Please refer to Figures 1 to 4 As shown, an embodiment of this utility model provides a telescopic engineering measurement pole, including an X-axis adjustment seat 1, a Y-axis adjustment seat 2, and a telescopic pole 3. A counterweight 4 is detachably installed at the bottom of the telescopic pole 3. In this embodiment, the counterweight 4 is spherically shaped and is rotatably connected to the inner side of the Y-axis adjustment seat 2. The Y-axis adjustment seat 2 is rotatably installed on the inner side of the X-axis adjustment seat 1. An angle adjustment mechanism is provided at the lower ends of both opposite sides of the X-axis adjustment seat 1.

[0027] In this embodiment, the X-axis adjusting seat 1 includes a first mounting seat 101, which is U-shaped. A first bushing 102 is fixedly connected to both inner ends of the first mounting seat 101. The Y-axis adjusting seat 2 includes a second mounting seat 201, which is U-shaped. A second bushing 203 is fixedly connected to both inner ends of the second mounting seat 201. A counterweight 4 is disposed inside the second mounting seat 201, and a connecting block 401 is fixedly connected to the top of the counterweight 4. A Y-axis shaft 402 is fixedly connected to the side of the first bushing 201. The end of the Y-axis shaft 402 away from the counterweight 4 is rotatably installed inside the second bushing 203. A side plate 202 is fixedly connected to the side of the second mounting base 201. The side plate 202 and the Y-axis shaft 402 are arranged parallel to each other. An X-axis shaft 204 is fixedly connected to one side of the side plate 202. The end of the X-axis shaft 204 away from the side plate 202 is rotatably installed inside the first bushing 102. The X-axis shaft 204 and the Y-axis shaft 402 are arranged perpendicular to each other.

[0028] By adopting the above technical solution, when the X-axis adjustment seat 1 is placed on the ground, the counterweight 4 rotates relative to the second mounting seat 201 about the Y-axis shaft 402 under its own weight. At the same time, the second mounting seat 201 rotates relative to the first mounting seat 101 about the X-axis shaft 204 under its own weight, thereby making the telescopic marker 3 fixed on the counterweight 4 in a vertical state.

[0029] In this embodiment, the telescopic marker 3 includes a first marker 301 and a second marker 302. The first marker 301 is tubular, and the lower end of the second marker 302 is slidably inserted into the first marker 301. The upper end of the first marker 301 is threadedly fitted with a handle bolt 303 for fixing the second marker 302 onto the first marker 301. With this configuration, the length of the telescopic marker 3 can be adjusted according to measurement needs. In actual use, the handle bolt 303 is loosened, and then the height of the second marker 302 is adjusted. After adjustment, the handle bolt 303 is tightened.

[0030] In this embodiment, the top of the connecting block 401 is provided with a threaded groove 403, and the bottom of the first marker 301 is fixedly connected to the mounting block 3011. The outer wall of the mounting block 3011 is provided with an external thread, and the mounting block 3011 is fixedly installed inside the threaded groove 403 by the thread. With this setting, when not in use, the first marker 301 can be removed from the counterweight block 4, which is convenient for carrying in the storage box.

[0031] In this embodiment, the angle adjustment mechanism includes a mounting plate 103 and a support block 106. The mounting plate 103 is fixedly installed on the lower side of the first mounting base 101. Both ends of the mounting plate 103 are threadedly connected to a handle screw 104. The bottom of the handle screw 104 is fixedly connected to a ball head 105. The top of the support block 106 is provided with a ball seat, and the ball head 105 is rotatably connected inside the ball seat.

[0032] By using the angle adjustment mechanism, when the ground tilt angle is too large, the angle of the first mounting base 101 can be adjusted by rotating the handle screw 104, so that the counterweight 4 does not contact the side plate 202, and the second mounting base 201 contacts the first mounting base 101.

[0033] The foregoing description illustrates and describes several preferred embodiments of the present invention. However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or techniques or knowledge in related fields. Any modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention should be within the protection scope of the appended claims.
