[0021] The present invention is further described in detail below in conjunction with the embodiments:

[0022] Example 1

[0023] like Figure 1-4 As shown, the utility model provides a foldable surveying instrument for urban planning surveying, including a base 1, one side of the base 1 is rotatably connected to a telescopic rod 2, the bottom of the telescopic rod 2 is rotatably connected to a fixed cone 3, the top of the base 1 is provided with a surveying device 4, and the inner wall of the base 1 is provided with a horizontal mechanism.

[0024] In this embodiment, a telescopic rod 2 is provided on one side of the base 1, and the telescopic rod 2 is pulled to adjust the fixed cone 3 provided at the bottom thereof, and the fixed cone 3 is inserted into the ground to fix the equipment. A surveying and mapping device 4 is provided on the top of the base 1, and the road surface is surveyed and mapped using the surveying and mapping device 4. When the surveying and mapping position is uneven, the angle of the surveying and mapping device 4 is adjusted using the horizontal mechanism provided on the inner wall of the base 1, so that the surveying and mapping device 4 always maintains a horizontal state, which further solves the problem that during the use of traditional surveying and mapping instruments for urban planning, due to the uneven road surface being surveyed, the operator needs to observe the tilt error of the surveying and mapping instrument while adjusting it, which is not only time-consuming and labor-intensive, but also the adjusted angle is not accurate enough, thereby resulting in inaccurate measurement data.

[0025] Example 2

[0026] like Figure 1-4 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the horizontal mechanism includes a rolling ball 5 rotatably connected to the middle part of the inner wall of the base 1, the top of the rolling ball 5 is fixedly connected to a fixed tube 6, the inner wall of the fixed tube 6 is threadedly connected to a counterweight block 7, a slide groove 8 is opened on one side of the inner wall of the base 1, the inner wall of the slide groove 8 is slidably connected to a steel ball 9, and one side of the steel ball 9 overlaps the outer wall of the rolling ball 5.

[0027] In this embodiment, a rolling ball 5 is arranged in the middle of the inner wall of the base 1, a fixed tube 6 is arranged at the bottom of the rolling ball 5, and a counterweight 7 is arranged on the inner wall of the fixed tube 6. By allowing the counterweight 7 to droop naturally, the rolling ball 5 is rolled in the base 1, so that the surveying and mapping equipment 4 arranged on the top of the rolling ball 5 is adjusted to keep the surveying and mapping equipment 4 moderately vertical. A slide groove 8 is arranged on one side of the inner wall of the base 1, and a steel ball 9 is arranged on the inner wall of the slide groove 8. When the rolling ball 5 rotates, the steel ball 9 is used to make it roll more smoothly, thereby reducing the error of the rolling ball 5 when it remains horizontal. This further solves the problem that during the use of traditional surveying instruments for urban planning, the operator needs to observe the error of the tilt of the surveying instrument while adjusting it due to the uneven road surface. This is not only time-consuming and labor-intensive, but also the adjusted angle is not accurate enough, resulting in inaccurate measurement data.

When the surveying and mapping equipment 4 needs to be adjusted in angle, the limit ring 12 is pressed to separate the limit ring 12 from the rolling ball 5. When the rolling ball 5 adjusts the angle to make the surveying and mapping equipment 4 horizontal, the limit ring 12 is loosened and the spring 11 is used to fix the limit ring 12 to the bottom of the rolling ball 5 again.

[0033] In this embodiment, a turntable 13 is provided on the top of the rolling ball 5, and the turntable 13 is rotated to realize the left and right rotation of the surveying and mapping device 4. A limit plate 14 is provided on the top of the turntable 13, and an adjusting rod 15 is provided on one side of the limit plate 14, and one end of the adjusting rod 15 is connected to the surveying and mapping device 4. By rotating the adjusting rod 15, the up and down rotation of the surveying and mapping device 4 is controlled.

[0034] The following is a detailed description of the working principle of the foldable surveying instrument for urban planning and surveying.

The steel ball 9 makes it roll more smoothly, thereby reducing the error of the ball 5 when it is kept horizontal, further solving the problem that during the use of traditional urban planning surveying instruments, the operator needs to observe the error of the surveying instrument's tilt while adjusting it due to the uneven road surface. This is not only time-consuming and laborious, but also the adjusted angle is not accurate enough, resulting in inaccurate measurement data. When the ball 5 adjusts the angle to make the surveying and mapping equipment 4 horizontal, the limit ring 12 is loosened and the spring 11 is used to fix the bottom of the ball 5 again.

Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
