Preferably, the middle part of each telescopic bracket fixing part is provided with a threaded through hole, and a bolt is spirally arranged in each threaded through hole.

Preferably, two the telescopic link all includes horizontal part and vertical part, and installs the spring between the lower terminal surface of every telescopic link up end and layer board.

Preferably, a bubble level gauge is horizontally arranged on one side of the supporting plate.

Preferably, the two T-shaped threaded rods respectively comprise a horizontal part and a vertical part, and a rubber block is fixed on the lower end face of the vertical part of each T-shaped threaded rod in a gluing mode.

The utility model has the advantages that: the utility model discloses in, through up end installation telescopic link and the spring in the backup pad, not only can fix the measuring instrument, the bubble spirit level on the layer board can also be better see out the fixed level situation of measuring instrument installation, can carry out manual regulation to the levelness of measuring instrument through the T shape threaded rod on adjusting the support, make the measuring instrument measure under more horizontally state, not only improved the measuring degree of accuracy, still better improvement measuring work efficiency.

Fig. 1 is a schematic front view of a portable stand for topographic survey according to the present invention;

fig. 2 is a schematic structural diagram of a telescopic bracket of a portable bracket for topographic survey according to the present invention.

In the figure: 1 backup pad, 2 fixed blocks, 3 telescopic bracket, 4 bubble spirit levels, 5 bolts, 6 staple, 7 supports, 8T shape threaded rod, 9 rubber blocks, 10 telescopic link, 11 layer boards.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-2, a portable support for topographic survey comprises a support plate 1, wherein fixed blocks 2 are fixedly arranged on two sides of the lower end surface of the support plate 1, a roller shaft is rotatably arranged in each fixed block 2, a telescopic support 3 is fixedly arranged on each roller shaft, each telescopic support 3 comprises a telescopic part and a fixed part, a fixing nail 6 is welded on the lower end surface of each telescopic support 3, a threaded through hole is formed in the middle of the fixed part of each telescopic support 3, a bolt 5 is spirally arranged in each threaded through hole to better fix the height of each telescopic support and avoid slipping during use, a support 7 is fixedly arranged on the upper end surface of the support plate 1, each support 7 comprises a vertical part and a horizontal part, threaded through holes are formed in two sides of the horizontal part of each support 7, a T-shaped threaded rod 8 is spirally matched in each threaded through hole, and each two T-shaped threaded rods 8 comprise a horizontal part and a vertical part, and the lower end surface of the vertical part of the T-shaped threaded rod 8 is glued and fixed with a rubber block 9, which can reduce the abrasion of the T-shaped threaded rod 8 on the surface of the measuring instrument when rotating, the levelness of the measuring instrument can be manually adjusted by adjusting the T-shaped threaded rod 8 on the support 7, so that the measuring instrument can measure in a more horizontal state, thereby not only improving the measuring accuracy, but also better improving the measuring work efficiency, the two sides of the upper end surface of the support plate 1 are provided with the telescopic rods 10, the support plate 11 is arranged and fixed between the upper end surfaces of the two telescopic rods 10, one side of the support plate 11 is horizontally provided with the bubble level meter 4, the horizontal state of the mounting and fixing of the measuring instrument can be better seen, the two telescopic rods 10 both comprise the horizontal part and the vertical part, and a spring is arranged between the upper end surface of each telescopic rod 10 and the lower end, and a certain adjusting space is reserved for adjusting the levelness of the measuring instrument by subsequently manually rotating the T-shaped threaded rod 8.
