Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
- 3 are please referred to Fig.1, the utility model provides a kind of technical solution：A kind of engineering mapping survey pin, including the first survey
The bottom end of pricker 1, first survey pin 1 is bolted with the second survey pin 2, and the outer wall lower weld of second survey pin 2 has supporting sephere
8, second survey pin 2 runs through supporting sephere 8, and the bottom end of second survey pin 2 is welded with pouring weight 4, the supporting sephere 8 it is outer
Wall is connected with linear bearing 7, and the ball in 7 inner cavity of the spring bearing is contacted with supporting sephere 8, a left side for the spring bearing 7,
Right end is welded with supporting rod 3, and the outer end of supporting rod 3 described in two groups is welded with fixed cylinder 13, fixed cylinder 13 described in two groups
Inner cavity is connected with telescopic rod 5, and the top of telescopic rod 5 described in two groups is welded with support leg 6, and the bottom of the pouring weight 4 is provided with
Deep hole, and ultrasonic wave module 9 and power module 10 are provided in deep hole, the ultrasonic wave module 9 is located under power module 10
The top front in portion, the pouring weight 4 is provided with groove, and relay 11 is provided in groove, the top front setting of the pouring weight 4
