Description

Technical Field

[0001] This utility model relates to the field of surveying instrument technology, and in particular to a portable high-precision positioning device. Background Technology

[0002] In surveying work, the use of surveying instruments is indispensable, and these instruments need to be installed on positioning devices during use. A patent with patent number "CN115355416A" and titled "A High-Precision Positioning Surveying Instrument for Engineering Surveying" includes a horizontally positioned support plate and a high-precision surveying instrument positioned above the support plate. The upper surface of the support plate has multiple accommodating grooves along a circumferential direction. Movable blocks are rotatably connected within the accommodating grooves. An installation cylinder is rotatably inserted into the movable block. A bottom support rod is threaded into the installation cylinder and coaxially fixed with a pin at its lower end.

[0003] However, the aforementioned surveying instrument still has certain drawbacks in some applications: Firstly, the angle of the base support rod cannot be adjusted, and the overall height is also easily adjustable, making it difficult to install and debug according to the site environment, thus reducing its practicality. Secondly, the inability to flexibly adjust the angle of the surveying instrument results in less than ideal positioning accuracy. Therefore, a positioning device specifically designed to address these shortcomings is proposed. Summary of the Invention

[0004] This invention overcomes the shortcomings of the prior art and provides a portable high-precision positioning device.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a portable high-precision positioning device, comprising: a positioning mechanism and a folding structure connected together by a mounting plate; the positioning mechanism includes: a support column that passes through the mounting plate; an assembly plate is provided at the top of the support column; a rotating disk is rotatably connected to the upper part of the assembly plate; a fixing block is integrally provided at the bottom inner side of the assembly plate; a drive rod is rotatably provided on the side of the fixing block; the drive rod is meshed with the rotating disk through a gear set; the folding structure includes: a plurality of telescopic rod groups arranged at equal angles on the bottom surface of the mounting plate; each of the telescopic rod groups is hinged to the bottom surface of the mounting plate; and the upper part of each telescopic rod group is hinged to the bottom end of the support column through a rotating rod; a cement nail is provided at the bottom end of each telescopic rod group.

[0006] In a preferred embodiment of the present invention, the gear set includes: a first bevel gear sleeved on the outer peripheral side of the drive rod, and a second bevel gear integrally disposed on the bottom of the rotating disk, wherein the first bevel gear and the second bevel gear cooperate with each other.

[0007] In a preferred embodiment of this utility model, a plurality of limiting rods are arranged in an array on the bottom surface of the assembly plate, and the plurality of limiting rods are slidably connected to the mounting plate.

[0008] In a preferred embodiment of this utility model, the telescopic rod assembly includes: a first bolt rod hinged to the bottom surface of the mounting plate, the first bolt rod being threadedly connected to a rotating sleeve, the rotating sleeve being threadedly connected to a second bolt rod, and the second bolt rod being hingedly connected to the cement nail.

[0013] (1) This utility model can adjust the opening angle of multiple telescopic rod groups according to the site environment to ensure that the surveying instrument can be stably fixed on the ground. While opening the telescopic rod group angle, the rotating rod will drive the support column to gradually extend out of the mounting plate, raising the height of the assembly plate, so that the surveying instrument can be raised to a certain height simultaneously. There is no need to adjust the height of the surveying instrument separately. Moreover, the height of the surveying instrument can be further adjusted by rotating the rotating sleeve, making it more convenient to use and more practical.

[0014] (2) This utility model rotates the drive rod, which drives the first bevel gear to rotate, and the first bevel gear drives the second bevel gear to rotate, thereby driving the rotating disk to rotate. According to the position of the indicator needle on the angle scale line, the angle of the surveying instrument is precisely adjusted, which effectively improves the positioning accuracy of the surveying instrument.

These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0023] like Figure 1 and Figure 2 As shown, a portable high-precision positioning device includes: a positioning mechanism and a folding structure connected together by a mounting plate 1. The positioning mechanism includes: a support column 2 that passes through the mounting plate 1, an assembly plate 3 at the top of the support column 2, a rotating disk 4 rotatably connected to the upper part of the assembly plate 3, a fixing block 5 integrally provided on the bottom inner side of the assembly plate 3, a drive rod 7 rotatably provided on the side of the fixing block 5, the drive rod 7 being connected to the rotating disk 4 through a gear set, a fixing plate 15 fixedly connected to the top surface of the rotating disk 4, and a surveying instrument 12 connected to the fixing plate 15.

[0024] like Figure 3 As shown, the folding structure includes: several telescopic rod groups 8 set at equal angles on the bottom surface of the mounting plate 1, all of which are hinged to the bottom surface of the mounting plate 1, and cement nails are installed at the bottom ends of the telescopic rod groups 8. The opening angle of multiple telescopic rod groups 8 can be adjusted according to the site environment to ensure that the surveying instrument 12 can be stably fixed on the ground. The upper part of the telescopic rod group 8 is hinged to the bottom end of the support column 2 through a rotating rod. When the telescopic rod group 8 is opened, the rotating rod will drive the support column 2 to gradually extend out of the mounting plate 1, raising the height of the assembly plate 3, so that the surveying instrument 12 is raised to a certain height simultaneously without the need for additional height adjustment of the surveying instrument 12. Several limiting rods 11 are arrayed on the bottom surface of the assembly plate 3, and the limiting rods 11 are slidably connected to the mounting plate 1. Through the cooperation of the limiting rods 11 and the mounting plate 1, the stability of the assembly plate 3 during movement is effectively improved.

[0025] In a preferred embodiment of this utility model, the telescopic rod assembly 8 includes: a first bolt rod 801 hinged to the bottom surface of the mounting plate 1; a rotating sleeve 803 threadedly connected to the first bolt rod 801; a second bolt rod 802 threadedly connected to the rotating sleeve 803; and a cement nail hinged to the second bolt rod 802. By rotating the rotating sleeve 803, the height of the surveying instrument 12 can be further adjusted, making it more convenient to use and more practical.

[0026] like Figure 4 and Figure 5 As shown, in a preferred embodiment of this utility model, the gear set includes: a first bevel gear 9 sleeved on the outer periphery of the drive rod 7; a second bevel gear 10 integrally formed on the bottom of the rotating disk 4; the first bevel gear 9 and the second bevel gear 10 cooperating with each other; and an annular protrusion 13 provided on the upper outer periphery of the rotating disk 4, which slidably connects to the mounting disk 3. By rotating the drive rod 7, the drive rod 7 drives the first bevel gear 9 to rotate, which in turn drives the second bevel gear 10 to rotate, thereby driving the rotating disk 4 to rotate. Based on the position of the indicator needle 6 on the angle scale line, the angle of the surveying instrument 12 is precisely adjusted, effectively improving the positioning accuracy of the surveying instrument 12. On the other hand, an annular level 14 is provided on the top surface of the mounting plate 1. Based on the annular level 14 provided on the top surface of the mounting plate 1, the surveying instrument 12 is adjusted to achieve the optimal level state, further improving the positioning accuracy of the surveying instrument 12.

[0027] In use, this utility model allows each telescopic rod assembly 8 to open at a certain angle, fixing the cement nail to the ground. As the telescopic rod assembly 8 opens, the rotating rod drives the support column 2 to gradually extend out of the mounting plate 1, causing the surveying instrument 12 to be raised to a certain height simultaneously. The rotating sleeve 803 in each of the different telescopic rod assemblies 8 is rotated until the bubbles in the level are evenly distributed. The drive rod 7 is then rotated, which drives the first bevel gear 9 to rotate. The first bevel gear 9 drives the second bevel gear 10 to rotate, thereby driving the rotating disk 4 to rotate and adjusting the angle of the surveying instrument 12.

[0028] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
