It connects in the bearing of mounting base lower surface, the surface of the threaded post is fixedly connected with first gear, the following table of the mounting base
Face is plugged with the second shaft, and the surface of second shaft is fixedly connected with second gear, the first gear and second gear
Engagement.
Preferably, the quantity of the support is three, and the side of fixed ring is arranged in three supports in the form of annular array
Face.
Preferably, the quantity of the threaded post is three, and the second gear is located between three threaded posts.
Preferably, the bottom end of the fixed feet is tip shape.
Preferably, the side of the mounting base is fixedly connected with air-bubble level.
Preferably, the bottom end of second shaft is fixedly connected with handle.
(3) beneficial effect
The present invention provides a kind of measurement tripods convenient for adjusting vertical direction height.Have it is following the utility model has the advantages that
The present invention passes through setting threaded hole, threaded post, mounting base, bearing, first gear, the second shaft and second gear,
So that rotating by second gear, while three threaded post rotations are driven, is rotated by threaded post, so that threaded post is in threaded hole
Interior lifting, so that mounting base moves in the vertical direction, to reach in the condition for not destroying tripod horizontality
Height adjustment on lower carry out vertical direction, greatly facilitates the use of tripod, its height is made to be more suitable for user's observation.

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
As shown in Figure 1-3, the present invention provides a kind of technical solution: a kind of convenient for adjusting the measurement of vertical direction height with three
Foot prop, including fixed ring 1, the side of fixed ring 1 are fixedly connected with support 2, and the quantity of support 2 is three, and three supports 2 are with ring
The side of fixed ring 1 is arranged in the form of shape array, and the inner wall of support 2 is fixedly connected with first rotating shaft 3, lives in first rotating shaft 3
It is dynamic to be connected with set leg 4, cover and be plugged with Retractive leg 5 in leg 4, the surface of set leg 4 is threaded with bolt 6, one end of bolt 6 with stretch
The surface of contracting leg 5 overlaps, and the bottom end of Retractive leg 5 is fixedly connected with fixed feet 7, and the bottom end of fixed feet 7 is tip shape, makes it possible to
Ground surface is punctured, to prevent slide displacement, the surface of fixed ring 1 offers threaded hole 8, and 8 internal screw thread of threaded hole is connected with spiral shell
Line column 9, the quantity of threaded post 9 are three, and second gear 14 is located between three threaded posts 9, and one end of threaded post 9 is plugged on peace
In the bearing 11 for filling 10 lower surface of seat, the side of mounting base 10 is fixedly connected with air-bubble level 15, and the surface of threaded post 9 is fixed
It is connected with first gear 12, the lower surface of mounting base 10 is plugged with the second shaft 13, and the bottom end of the second shaft 13 is fixedly connected with
Handle 16, the surface of the second shaft 13 are fixedly connected with second gear 14, and first gear 12 is engaged with second gear 14.
In use, three set legs 4 are unfolded, the length of Retractive leg 5 is adjusted and observe air-bubble level 15 simultaneously, make three feet
Frame keeps horizontal, measuring instrument is mounted in mounting base 10, according to the height of user, rotating handle 16 makes second gear
14 linkage first gears 12, to drive threaded post 9 to rotate, so that mounting base 10 is gone up and down, to adjust the height of tripod
Degree.
It can to sum up obtain, the present invention passes through setting threaded hole 8, threaded post 9, mounting base 10, bearing 11, first gear 12, the
Two shafts 13 and second gear 14 so that rotating by second gear 14, while driving three threaded posts 9 to rotate, pass through screw thread
Column 9 rotates, so that threaded post 9 is gone up and down in threaded hole 8, so that mounting base 10 moves in the vertical direction, to reach
Height adjustment on vertical direction is carried out under conditions of not destroying tripod horizontality, greatly facilitates making for tripod
With, make its height be more suitable for user observation.
