Description

Technical Field

[0001] This utility model relates to the field of surveying instrument technology, specifically to a conveniently adjustable surveying instrument for architectural design. Background Technology

[0002] A surveying instrument is used for measuring and drawing maps, topographic maps, engineering drawings, cadastral maps, etc. It is an important tool in modern geographic information technologies such as Geographic Information Systems (GIS) and Global Positioning Systems (GPS). The principles of a surveying instrument mainly include distance measurement, direction finding, and measurement data processing. Surveying instruments are typically equipped with laser or electronic distance measuring instruments. They utilize a transmitter to emit laser or electromagnetic waves, and a receiver to receive the reflected signals. The distance is calculated by measuring the time difference or frequency difference of the signals. This distance measurement principle enables high-precision distance measurement and is widely used in topographic surveying, building surveying, and other fields. Surveying instruments are also typically equipped with a total station or electronic compass, which uses the Earth's magnetic field or constellation signals to determine the azimuth of a measurement point. This direction finding principle enables high-precision azimuth measurement and is widely used in map making, cadastral surveying, and other fields.

[0003] When using a surveying instrument, it needs to be supported and fixed by a support platform and connecting frame. Although the surveying instrument can be adjusted in a small range of directions, it cannot be turned as a whole. When it is necessary to turn as a whole, the entire support frame and support platform need to be moved. After the movement is completed, it needs to be readjusted. At the same time, after long-term use, the support legs of the existing support frame tend to expand outward when providing support, resulting in overall imbalance. Utility Model Content

[0004] This utility model addresses the problem that existing support legs tend to expand outwards after prolonged use, leading to overall imbalance. To solve this, it provides a conveniently adjustable architectural design surveying instrument, including a mounting platform. A bearing is installed inside the mounting platform, and a worm gear is rotatably connected inside the bearing. The surveying instrument is fixedly connected to the top of the worm gear. A cover is installed on the top of the mounting platform. A worm is driven through the surface of the worm gear, and a bearing is rotatably connected to the surface of the worm. A rotating handle is fixedly connected to one end of the worm. A threaded sleeve is fixedly connected to the bottom of the mounting platform, and a threaded rod is threadedly connected inside the threaded sleeve.

[0005] Through the above technical solution, by setting a worm gear, after the overall surveying instrument is fixed, the position of the surveying instrument can be changed through the worm gear, which is convenient for surveying work in different positions. Furthermore, the threaded sleeve makes it easy to separate the mounting platform from the overall connecting platform, which is convenient for disassembly after the surveying instrument is used, and facilitates recycling.

[0006] As a further improvement to the above solution, the top of the worm gear is located above the top of the bearing, and the surveying instrument penetrates the top of the mounting platform.

[0007] With the above technical solution, the top of the worm gear is positioned above the bearing and the surveying instrument passes through the top of the mounting platform. This design ensures that the surveying instrument can be stably mounted on the mounting platform and rotate smoothly under the drive of the worm gear without being obstructed by the structure of the mounting platform, thus ensuring the normal realization of the surveying instrument's angle adjustment function.

[0008] As a further improvement to the above solution, the left end of the worm gear penetrates the inner wall of the mounting platform, and there are two bearings, which are symmetrically and evenly distributed on the inner wall with respect to the top center of the mounting platform.

[0009] Through the above technical solution, the left end of the worm gear penetrates the inner wall of the mounting platform, allowing the rotation handle to be located outside the mounting platform for convenient operation. The two bearings are symmetrically and evenly distributed inside the mounting platform with respect to the top center, which can stably support the rotation of the worm gear, reduce shaking and deviation during rotation, improve the accuracy of transmission, and thus ensure the precision of the surveying instrument angle adjustment.

[0010] As a further improvement to the above solution, the handle is mounted on a worm gear that penetrates one end of the inner wall of the mounting platform.

[0011] With the above technical solution, operators can easily grasp the handle and turn the worm gear, thus easily adjusting the surveying instrument.

[0012] As a further improvement to the above solution, a connecting platform is fixedly connected to the bottom of the threaded rod, an installation sleeve is fixedly connected to the bottom of the connecting platform, a movable column is sleeved inside the installation sleeve, connecting frames are fixedly connected to both ends of the movable column, a limit plate is fixedly connected inside the connecting frame, a support column is fixedly connected to the bottom of the connecting frame, a cone head is fixedly connected to the bottom of the support column, and a limit platform is fixedly connected to the bottom of the mounting platform.

[0013] The above technical solution, by setting a limiting platform, can limit the position of the support column to a suitable opening position when fixing the surveying instrument, thus avoiding excessive opening of the support column and causing instability of the machine.

[0014] As a further improvement to the above solution, the threaded rod is positioned at the top center of the connecting platform.

[0015] With the above technical solution, the threaded rod is set at the top center of the connecting platform. This ensures uniform force transmission during operations such as height adjustment, making the entire device uniformly stressed and avoiding structural tilting or instability caused by uneven force, thereby further ensuring the stability of the surveying instrument during operation.

[0016] As a further improvement to the above solution, the number of mounting sleeves is set to three, and the three mounting sleeves are distributed in a circle around the bottom of the connecting platform, and the limiting plate is set inside the limiting platform.

[0017] With the above technical solution, the three mounting sleeves are distributed in a circular pattern at the bottom of the connecting platform, which can provide stable support force in all directions for the entire support structure. The limiting plate is set inside the limiting platform, which precisely limits the range of motion of the movable column, making the structure of the entire device more compact and stable, and helping to improve the stability of the surveying instrument during operation.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This utility model, by setting a worm gear, allows the position of the surveying instrument to be changed after the overall surveying instrument is fixed, facilitating surveying work at different positions. Furthermore, the threaded sleeve makes it easy to separate the mounting platform from the overall connecting platform, making it convenient to disassemble and recycle the surveying instrument after use.

[0020] This invention, by setting a limiting platform, can limit the position of the support column to a suitable opening position when fixing the surveying instrument, thus preventing the support column from opening too wide and causing instability of the machine. Attached Figure Description

[0029] The top of the worm gear 3 is located above the top of the bearing 2, and the surveying instrument 4 passes through the top of the mounting platform 1.

[0030] The left end of the worm gear 6 penetrates the inner wall of the mounting platform 1. Two bearings 7 are provided, symmetrically and evenly distributed on the inner wall with respect to the top center of the mounting platform 1.

[0031] The handle is set on the worm gear 6 that passes through one end of the inner wall of the mounting platform 1.

[0032] A connecting platform 11 is fixedly connected to the bottom of the threaded rod 10. A mounting sleeve 12 is fixedly connected to the bottom of the connecting platform 11. A movable column 13 is sleeved inside the mounting sleeve 12. A connecting frame 14 is fixedly connected to both ends of the movable column 13.
