This method is not convenient for effective fine adjustment of the measuring instrument, and the method of adjusting the level of the measuring instrument by the support legs is not good. Therefore, the existing technology lacks a mechanism for fine adjustment of the measuring instrument, which affects the accuracy of the measurement. To address this, we designed a surveying instrument support to provide an alternative technical solution to the above technical problems. Utility Model Content

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Please see Figure 1-7 This utility model provides a technical solution: a surveying instrument support, including a support plate 1, an assembly plate 2 mounted on the top of the support plate 1, clamping plates 4 slidably connected to both sides of the top of the assembly plate 2, and an adjustment mechanism for leveling the measuring instrument between the support plate 1 and the assembly plate 2. The adjustment mechanism includes a threaded cylinder 13, a threaded adjusting rod 14, a universal shaft 16 and a handwheel 17. The top of the support plate 1 is fixed with the threaded cylinder 13, the top of the inner side of the threaded cylinder 13 is threadedly connected with the threaded adjusting rod 14, the top of the threaded adjusting rod 14 is slidably connected with the universal shaft 16, and the end of the universal shaft 16 away from the support plate 1 is fixed to the assembly plate 2.

[0028] When in use, when it is necessary to support the measuring instrument for surveying, the measuring instrument is placed on the assembly plate 2 and clamped and fixed by two buffer pads 3, thereby effectively assembling the measuring instrument and effectively surveying the building construction.

[0029] When it is necessary to survey the construction of the area, and when it is necessary to make fine adjustments to the measuring instrument, the threaded adjusting rod 14 and the threaded cylinder 13 in the rotary adjusting mechanism rotate in a threaded manner, so that the threaded adjusting rod 14 adjusts the universal shaft 16 up and down, and the universal shaft 16 effectively rolls in a universal direction with the threaded adjusting rod 14, so that the three threaded adjusting rods 14 drive the universal shaft 16 to make fine adjustments to the level of the assembly plate 2, so as to adjust according to the level requirements of the measuring instrument;

[0030] At this time, the three threaded cylinders 13, the threaded adjusting rod 14 and the universal joint 16 effectively lift the horizontal direction of the support plate 1, thereby effectively adjusting the horizontal accuracy.

[0031] A fixing block 7 is fixed at the bottom end of the support plate 1. An adjusting screw 10 is rotatably connected to the bottom end of the fixing block 7. A threaded sleeve 11 is threadedly connected to the outer side of the adjusting screw 10. A linkage seat 12 is rotatably connected to the outer side of the threaded sleeve 11. Support rods 15 are rotatably connected to the four ends of the outer side of the linkage seat 12. The end of the support rod 15 away from the adjusting screw 10 is rotatably connected to the support column 5.

[0032] Specifically, when the device needs to be deployed and supported, the threaded sleeve 11 is rotated to drive the adjusting screw 10 to make a threaded connection. The threaded sleeve 11 drives the linkage seat 12 to adjust up and down along the guide of the adjusting screw 10, so that the linkage seat 12 drives the support rod 15 to squeeze, thereby the support rod 15 applies pressure to the support column 5, so that the support column 5 drives the extension leg 6 to unfold in a direction away from each other, thereby effectively supporting the surveying instrument.

[0033] The top of the inner side of the assembly plate 2 is rotatably connected to a positive and negative threaded rod 18. The two ends of the positive and negative threaded rod 18 are respectively threaded to the clamping plate 4. By rotating the positive and negative threaded rod 18, the two clamping plates 4 are driven to move closer to each other to clamp the measuring instrument. Therefore, the measuring instrument can be effectively disassembled and assembled.

[0034] Several buffer pads 3 are fixed at the ends of the two clamping plates 4 that are far apart from each other, and the buffer pads 3 effectively protect the measuring instrument.

[0035] A testing instrument is clamped between two clamping plates 4. Support columns 5 are rotatably connected to the four ends of the bottom of the support plate 1. An extension foot 6 is slidably connected to the inner side of the support column 5. A positioning component for limiting the extension foot 6 is provided on the outer side of the extension foot 6. The positioning component includes a limiting hole 8 and a limiting bolt 9. A limiting bolt 9 is threaded on one side of the bottom outer side of the limiting bolt 9. Several limiting holes 8 are opened inside the extension foot 6. One end of the limiting bolt 9 passes through the support column 5 and is threaded to the corresponding limiting hole 8.

[0036] Specifically, when the height of the testing instrument needs to be adjusted, the extension foot 6 is pulled along the guide of the support column 5 to extend, thereby effectively adjusting the height of the surveying instrument. When the extension foot 6 and the support column 5 are extended to a certain height, the limit bolt 9 is rotated to drive the corresponding limit hole 8 inside the extension foot 6 to make a threaded connection, thereby effectively positioning the extension foot 6 to ensure the stability and flexibility of the device.

[0037] A handwheel 17 is fixed to the top of the outer side of the threaded adjusting rod 14. The handwheel 17 drives the threaded adjusting rod 14 to rotate. The threaded adjusting rod 14 is threadedly connected to the threaded cylinder 13, thereby effectively adjusting the level of the assembly plate 2 and the measuring instrument.

[0038] The bottom end of the extension leg 6 is rotatably connected to a support base, and the bottom end of the support base is fixed with an anti-slip seat. The stability of the device is improved by the support base and the anti-slip seat.

[0039] The usage process of the surveying instrument support provided by this utility model is as follows:

[0040] The measuring instrument is placed on the assembly plate 2. The positive and negative threaded rods 18 on the inner side of the assembly plate 2 are rotated, and the two clamping plates 4 on the outer ends of the rods move in opposite directions respectively. The measuring instrument is clamped and fixed by the buffer pads 3 at the ends of the clamping plates 4, so as to realize the quick disassembly and assembly of the instrument.

[0041] When the level of the measuring instrument needs to be adjusted, the handwheel 17 at the top of the threaded adjusting rod 14 in the adjustment mechanism is rotated, causing the threaded adjusting rod 14 and the threaded cylinder 13 at the top of the support plate 1 to rotate threadedly, thereby driving the universal joint 16 at the top to move up and down. Since the universal joint 16 can roll in all directions with the threaded adjusting rod 14, the level of the assembly plate 2 can be finely adjusted by adjusting the combination structure of the three threaded cylinders 13, the threaded adjusting rod 14 and the universal joint 16 respectively, so as to meet the level accuracy requirements of the measuring instrument.

[0042] When the device is deployed, the threaded sleeve 11 on the outside of the adjusting screw 10 connected to the bottom fixing block 7 of the rotating support plate 1 drives the linkage seat 12 to move up and down along the adjusting screw 10. The support rods 15 at the four ends of the linkage seat 12 then squeeze the support column 5, causing the support column 5 to drive the extension foot 6 to unfold outward, forming a stable support.

[0043] Then, pull the extension leg 6 along the inside of the support column 5 to adjust the overall height. When the required height is reached, rotate the limiting bolt 9 on the outside of the support column 5 so that it passes through the support column 5 and is threaded into the corresponding limiting hole 8 inside the extension leg 6, thus positioning the extension leg 6. At the same time, the support seat and anti-slip seat at the bottom of the extension leg 6 further enhance the stability of the support.

[0044] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
