Description
Technical field
It the utility model is related to a kind of GPS control points mark.
Background technology
In engineering, GPS control points mark be it is essential, it be to engineering structure precision it is very important, it is existing
GPS control points mark be all that crosshair is set at the top of spherical crown surface, a device that can fix tape measure end is not provided,
Generally measurement staff is that tape measure end is stepped down on the mark of GPS control points with pin, or is directly smoothed out with the fingers tape measure directly with hand
Tape measure end is withstood on the mark of GPS control points, carrys out measuring instrument height, when external wind is bigger, passes through above-mentioned two
It is difficult that tape measure end is placed on the mark of GPS control points that kind method, which is, can thus influence engineering survey precision.
Utility model content
The purpose of this utility model is overcome the deficiencies in the prior art, there is provided a kind of GPS control points mark, to solve
Tape measure end does not have the problem of local fixation in measurement process.
The utility model is achieved through the following technical solutions：
A kind of GPS control points mark, including marker post, the marker post top surface are spherical crown surface, the spherical crown surface is provided with
For the crosshair as measurement basic point, the tape measure that the marker post top side is provided with for tangling tape measure end is linked up with,
The tape measure hook includes support bar and is arranged at the hanging plate of support bar top, and the support bar bottom connects with marker post side
Connect, the hanging plate is horizontally disposed and is stretched out to spherical crown surface side, and gap is left between the hanging plate and spherical crown surface, the hanging plate
Cross section in fan ring-type, and it is described fan ring two circular arc lines with the marker post concentric.
The support bar is L-shaped support bar.
The utility model has advantages below compared with prior art：
A kind of GPS control points mark provided by the utility model, it is provided with for tangling volume in marker post top side
The tape measure hook of ruler end part, as long as tape measure end is inserted in the gap between hanging plate and spherical crown surface, you can fixed volume well
Ruler end part, so as to avoid, due to the bending of tape measure blade caused by wind, ensure that engineering survey precision, efficiently solve survey
Tape measure end does not have the problem of local fixation during amount, improves engineering survey efficiency.And the utility model is simple in construction, operation
It is convenient.
Brief description of the drawings
Fig. 1 is front view of the present utility model.
Fig. 2 is top view of the present utility model.
Fig. 3 is the utility model use state diagram.
Label in figure：1 marker post, 2 spherical crown surfaces, 3 crosshairs, 4 support bars, 5 hanging plates, 6 tape measures.
Embodiment
Embodiment of the present utility model is elaborated below, the present embodiment using technical solutions of the utility model before
Put and implemented, give detailed embodiment and specific operating process, but the scope of protection of the utility model is unlimited
In following embodiments.
Referring to Fig. 1 and Fig. 3, present embodiment discloses a kind of GPS control points mark, including marker post 1, the top surface of marker post 1
For spherical crown surface 2, spherical crown surface 2 is provided with the crosshair 3 being used for as measurement basic point, and the top side of marker post 1 is provided with for hanging
Firmly the tape measure 6 of the end of tape measure 6 is linked up with, and the hook of tape measure 6 includes support bar 4 and is arranged at the hanging plate 5 at the top of support bar 4, support bar 4
For L-shaped support bar, the bottom of support bar 4 is connected with the side of marker post 1, and hanging plate 5 is horizontally disposed and is stretched out to the side of spherical crown surface 2, hangs
Leave gap between plate 5 and spherical crown surface 2, the cross section of hanging plate 5 in fan ring-type, and fan two circular arc lines of ring with marker post 1
Concentric.
In use, the bottom of marker post 1 is inserted into underground, the spherical crown surface 2 of marker post 1 is exposed, the end of tape measure 6 is inserted
Enter in the gap between hanging plate 5 and spherical crown surface 2, you can fix the end of tape measure 6, so as to avoid due to tape measure 6 caused by wind
The bending of blade, it ensure that engineering survey precision.Wherein in fan ring-type, the end of tape measure 6 can be from link for the cross section of hanging plate 5
Each side insertion, to meet the requirement of measuring instrument height on measurement different directions.
Preferred embodiment of the present utility model is these are only, it is all in this practicality not to limit the utility model
All any modification, equivalent and improvement made within new spirit and principle etc., should be included in guarantor of the present utility model
Within the scope of shield.
