Example 1

As shown in fig. 1-4, the utility model provides a pair of engineering survey tripod, including set square 1, set square 1 center is equipped with connecting hole 11, and connecting hole 11 is used for being connected with measuring equipment. Each side surface of the triangular plate 1 is provided with a rotating groove 12, each rotating groove 12 is rotatably connected with a rotating block 2 through a first rotating shaft, the lower side of each rotating block 2 is fixedly connected with two supporting rods 3, one opposite side of each supporting rod 3 is provided with a sliding groove 31, a supporting plate 4 is slidably connected between the two sliding grooves 31, one side of each supporting rod 3 is provided with a first threaded hole, each first threaded hole is internally connected with a first bolt 32 in a threaded fit manner, each first bolt 32 can tightly abut against the side wall of the supporting plate 4 through the first threaded hole, by controlling the support plate 4 to slide between the two sliding grooves 31 and changing the angle of the rotating block 2 in the rotating groove 12, the height of the instrument during measurement can be adjusted, and the measuring instrument is adjusted to be in a horizontal state, and the supporting plate 4 is fixed between the two supporting rods 3 through the two first bolts 32 after the adjustment is finished, so that the stability of the tripod is ensured. All common sliding connection clamp plate 7 on two bracing pieces 3 that every turning block 2 was equipped with, every clamp plate 7 both sides all are equipped with the second screw hole, and the downthehole equal screw-thread fit of every second screw connects second bolt 71, and every second bolt 71 all can tightly support at bracing piece 3 lateral wall through the second screw hole. After the supporting plate 4 is fixed between the two supporting rods 3 by using the first bolt 32, the pressing plate 7 is slid to press the pressing plate 7 tightly on the upper side of the supporting plate 4, and then the second bolt 71 is rotated to fix the pressing plate 7 on the supporting rods 3, thereby further improving the stability of the tripod.

A square groove 41 is arranged at the lower side of each supporting plate 4, and a supporting device 6 is arranged in each square groove 41. The support device 6 can be supported on a soft floor surface and can also be supported on a hard floor surface. The supporting device 6 comprises a supporting block 61, the supporting block 61 is rotatably connected in the square groove 41 through a second rotating shaft, a conical column 62 is fixedly connected to the lower side of the supporting block 61, fixing plates 63 are fixedly connected to two sides of the supporting block 61, through holes are formed in each fixing plate 63, fixing rods 64 are slidably connected in each through hole, and a baffle 65 is fixedly connected to one end of each fixing rod 64. Each fixing rod 64 is sleeved with a spring 66, each spring 66 is fixedly connected between the baffle plate 65 and the fixing plate 63, and in a free state, the springs 66 can pull the baffle plate 65 to cling to one side of the fixing plate 63. Two first jacks are arranged at the lower side of the supporting plate 4.
