Specific embodiment
The utility model feature and other correlated characteristics are described in further detail by embodiment below in conjunction with attached drawing,
In order to the understanding of technical staff of the same trade:
As shown in figures 1 to 6,1-12 is marked to respectively indicate in figure are as follows: measurement mark core 1, tape measure ontology 2, tape measure 3, magnetic absorption
Device 4, mold 5, magnet 6, groove 7, convex block 8, magnet 9, card slot 10, measuring device 11, mold 12.
Embodiment: the present embodiment is specifically related to a kind of antenna height measuring device, is mainly used for measuring instrument in GPS measurement
It is high.
As shown in Figure 1, the device includes measurement mark core 1, it is erected at measuring device 11 and tape measure sheet that measurement mark core 1 is hit exactly
Body 2.
Measuring device 11 is erected at the center of measurement mark core 1, for carrying out essence to benchmark control point locating for measurement mark core 1
Survey grid control measurement.Magnet 9 is buried in the underface of the top part of measurement mark core 1, the later period measures operation Shi Keyu magnetic
Property adsorbent equipment 4 generate absorption, even if measurement slant height, tape measure 3 without departing from measurement mark core 1 center, improve accuracy of reading
Property.The end position of tape measure 3 is arranged in magnetic absorption device 4, when tape measure 3 is close to measurement mark core 1, passes through magnetic absorption device
The magnetic force generated between 4 and magnet 9 can make the end of tape measure 3 be fitted in the surface of measurement mark core 1, while making tape measure 3 and surveying
It is positioned and is fixed by the magnetic picture between magnetic absorption device 4 and magnet between amount mark core 1.And then tape measure 3 is stretched to survey
It measures at 11 antenna of equipment, accurately measures slant height, the height of measuring device 11 is calculated by Pythagorean theorem.
As shown in Fig. 2,3,4,5, magnetic absorption device 4 includes mold 5, mold 12, magnet 6.Magnetic absorption device 4
Bottom surface and the top surface curved surface of measurement mark core 1 fit, and the measurement starting point of tape measure 3 is zero, improves the accuracy of reading.
Mold 5 and mold 12 are symmetricly set on the two sides of 3 end of tape measure, for placing magnet 6.Magnet 6 is distinguished embedding
Enter in mold 5 and mold 12, using the magnetic pole principle that there is a natural attraction between the sexes, two magnets 6 mutually adsorb and are fixed on the end of tape measure 3
Portion two sides.As shown in fig. 6, the fitting tape measure 3 of mold 5 opens up fluted 7 on one side, the one side correspondence that mold 12 is bonded tape measure 3 is set
There is convex block 8, mold 5 and mold 12 can be made to connect and compose an entirety, guarantee connection between the two by the insertion of male-female engagement
Intensity.The cross dimensions of mold 5 and mold 12 is greater than the cross dimensions of tape measure 3, and groove 7 is located at the edge of mold 5, does not need
The structure for destroying 3 script of tape measure, that is, do not need to set groove on tape measure 3.Mold 5 and the magnet 6 of one side are integrated knot
Structure, mold 12 and the magnet 6 of one side are structure as a whole, and using the principle that there is a natural attraction between the sexes of magnet 6, may make in mold 5
Groove 7 and mold 12 in convex block 8 it is automatically chimeric, to realize simple assembling, dismantle simple and fast.It similarly, can also be
Convex block 8 is set on mold 5, groove 7 is opened up to realize assembly between the two by male-female engagement on the mold 12.
In the specific implementation, tape measure 3 is L-shaped for this case, opens up card slot 10 in the bottom of mold 5, can be vertical by 3 end of tape measure
The horizontal component of tape measure 3 is avoided to be exposed to magnetic absorption that is, in hook end insertion card slot 10 in the part in 3 scale direction of tape measure
The outside of device 4 causes to wear, and reduces the service life of tape measure 3.When to utilize the hook end of L-shaped tape measure 3, by magnetic
Property adsorbent equipment 4 removed from tape measure 3, that is, can be used, it is very convenient.
Mold 5 and mold 12 are equal in magnitude, open up groove 7 on four angles of mold 5, right on 12 4 angles of mold
It should be equipped with convex block 8, further strengthen the bonding strength of mold 5, mold 12 and tape measure 3.
Although above embodiments are elaborated referring to conception and embodiment of the attached drawing to the utility model aim,
But those skilled in the art will realize that still may be used in the case where no disengaging claim limits the precondition of range
To make various modifications and variations to the utility model, such as the shape of adsorbent equipment, the position and quantity etc. of groove and convex block, therefore
It will not repeat them here.
