[0032] like Figure 1-Figure 10 As shown, a surveying and mapping device for urban and rural planning and construction includes a theodolite 4. The bottom of the theodolite 4 is provided with an adjusting mechanism 1 for adjusting its height, and also includes a supporting mechanism 2 for lifting the adjusting mechanism 1.

[0033] In this embodiment: the adjustment mechanism 1 includes a bracket tube 11, a bracket seat 14 is fixed to the outside of the bracket tube 11, a first threaded hole is opened at the upper end of the bracket tube 11, a threaded tube 12 matching with it is arranged in the first threaded hole of the bracket tube 11, a screw bracket 13 is threadedly connected to the inside of the threaded tube 12, and a mounting seat for supporting the theodolite 4 is fixed to the end of the screw bracket 13 extending out of the threaded tube 12. The threaded tube 12 is extended from the upper end of the bracket tube 11 by rotating it, and the height of the theodolite 4 is raised by pressing the threaded tube 12 and rotating the screw bracket 13 at the same time. At this time, the support mechanism 2 is flipped and supported by the bracket seat 14.

[0034] In this embodiment: the support mechanism 2 includes three groups of telescopic legs, and a sliding bracket 23 is provided between the three groups of telescopic legs. The lower end of the sliding bracket 23 is rotatably connected to the toggle bracket 29. The lower end of each telescopic leg is fixed with a fixing mechanism 3. Each telescopic leg is composed of a telescopic leg 22 and a flip leg 21. The upper end of the telescopic leg 22 is slidably connected to the inside of the flip leg 21. The flip leg 21 has a groove on one side facing the sliding bracket 23. A flip bracket 213 is fixed on the side facing the sliding bracket 23 of the flip leg 21. A limited sliding groove 214 is provided at the lower end of the flip leg 21. The inside of the flip leg 21 is located at the flip bracket 213. A locking plate 25 is provided at the position, and teeth for cooperating with the groove teeth of the telescopic leg 22 are provided on one side of the locking plate 25. Guide plates are provided at the upper and lower ends of the other side of the locking plate 25. The position of the flip leg 21 located at the flip bracket 213 is provided with a locking slide groove 211 for sliding the guide plate. A supporting link 24 is provided between the sliding bracket 23 and the flip bracket 213. A sliding support rod 28 is slidably connected to the lower side of the supporting link 24. An arc push rod 27 is hinged at one end of the sliding support rod 28. A flip support 26 is provided at one end of the arc push rod 27. The flip support 26 is hinged on the flip bracket 213, and a useful The flip bracket 26 is provided with a notch for flipping, and the other end of the sliding support rod 28 is provided with an arc-shaped inclined surface, and the outer side of the toggle bracket 29 is provided with a lever for pushing the arc-shaped inclined surface of the sliding support rod 28. The flip bracket 213 is hinged to one end of the support link 24, and the sliding bracket 23 is hinged to the other end of the support link 24. By adjusting the position of the sliding bracket 23 on the lower side of the bracket tube 11, the support link 24 can be opened or closed by the flip leg 21. In addition, before the flip leg 21 is opened outward, the telescopic leg 22 in the flip leg 21 is pulled out, and then the entire device is supported by the fixing mechanism 3. In addition, the telescopic leg 22 After the flip leg 21 is extended to a certain length, the bracket 29 is rotated to allow its lever to push the end of the sliding support rod 28, and then the sliding support rod 28 on the lower side of the supporting connecting rod 24 slides toward the flip leg 21. At this time, the sliding support rod 28 pushes the arc-shaped push rod 27 to flip the flip support 26 into the flip slot 212, and the end of the flip support 26 pushes the locking plate 25 along the locking slot 211 to fit the sliding bracket 23. When the teeth of the locking plate 25 cooperate with the grooves of the telescopic leg 22, the three telescopic legs 22 can be quickly locked at the same time, thereby improving the limiting and fixing speed of the entire telescopic leg 22.

[0035] In this embodiment: the sliding bracket 23 is slidably connected to the bracket seat 14, an annular groove is provided at the lower end of the sliding bracket 23, a guide ring for sliding in the annular groove is fixed to the upper end of the toggle bracket 29, the upper end of the flip leg 21 is hinged to the bracket seat 14, and a magnetic ring for adsorbing on the lower end of the bracket tube 11 is fixed to the lower end of the toggle bracket 29. The magnetic ring at the lower end of the toggle bracket 29 is used to adsorb and fix on the lower end of the bracket tube 11, thereby preventing the sliding bracket 23 from sliding upward, and also preventing the toggle bracket 29 from spinning when pushing the sliding support rod 28.

[0036] When the cam 31 is in the unlock state, the locking nut 33 is engaged with the locking nut 33 and the locking nut 33 is engaged with the locking nut 33. When the cam 31 is unlocked, the locking nut 33 is engaged with the locking nut 33 and the locking nut 33 is engaged with the locking nut 33.

[0037] Working principle: When the theodolite 4 needs to be supported during use, the sliding bracket 23 on the bracket tube 11 is slid downward to push the three flip legs 21 outward through the support link 24. At this time, the three flip legs 21 drive the corresponding telescopic legs 22 to flip outward and open. In addition, any flip leg 21 can be flipped and the sliding bracket 23 can be driven to slide downward through the three support links 24 to push the remaining two flip legs 21 outward.

[0038] When the toggle bracket 29 at the lower end of the sliding bracket 23 is fitted to the lower end of the bracket tube 11, the three supporting connecting rods 24 completely open the three flip legs 21 outwards, and then the magnetic ring of the toggle bracket 29 is attracted to the lower end of the bracket tube 11, and the fixing seat 31 is pulled out downward or stepped on to make the limit rod 32 slide out from the lower end of the flip leg 21. In this process, the two limit lock tongues 33 will approach each other along the limit slide groove 214, and the limit rod 32 will be released from the lock, and then the telescopic leg 22 will begin to extend from the lower end of the flip leg 21. When the fixing seat 31 is against the ground, the support seat 14 is held by hand to adjust whether the entire support mechanism 2 is in a horizontal state according to the level meter on the theodolite 4;

[0039] After the support mechanism 2 is in a horizontal state, the support 29 is rotated to allow its lever to push the end of the sliding support rod 28, and then the sliding support rod 28 on the lower side of the supporting connecting rod 24 slides toward the flip leg 21. At this time, the sliding support rod 28 pushes the arc push rod 27 to flip the flip support 26 into the flip slot 212, and the end of the flip support 26 pushes the locking plate 25 along the locking slot 211 to fit the sliding support 23. When the teeth of the locking plate 25 cooperate with the grooves of the telescopic legs 22, the three telescopic legs 22 can be quickly locked at the same time, thereby improving the limiting and fixing speed of the entire telescopic legs 22, which is convenient for rapid installation and support during surveying and mapping.

[0040] When the height of the theodolite 4 needs to be adjusted, the height of the three telescopic legs 22 extending out of the flip legs 21 can be adjusted, or the threaded cylinder 12 can be rotated to extend it from the upper end of the bracket cylinder 11, and the threaded cylinder 12 can be pressed and the screw bracket 13 can be rotated to raise the height of the theodolite 4, and then the surveying and mapping process can be carried out;

[0041] When the entire flip leg 21 and the telescopic leg 22 need to be folded up, the bracket 29 is rotated in the opposite direction to no longer push the sliding support rod 28. At this time, the flip support 26 and the arc push rod 27 will flip downward with the support point of the flip bracket 213 as the center due to gravity, and the sliding support rod 28 will slide toward the bracket tube 11. At this time, the locking plate 25 no longer locks the groove teeth of the telescopic leg 22. At this time, the telescopic leg 22 can be retracted into the flip leg 21, and the telescopic leg 22 can be limited by the fixing mechanism 3 to prevent it from extending out. At the same time, the sliding bracket 23 is pulled upward to allow the three supporting connecting rods 24 to drive the flip leg 21 to close.

[0042] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
