It is a device specially used for engineering measurement.

[0003] In the process of engineering surveying and mapping data collection, GPS is needed to measure the topography of the project. Before each measurement, the GPS needs to be restarted and the data in the GPS needs to be calibrated. During calibration, the GPS needs to be placed on a known coordinate point for data calibration. Each time the data is checked, the staff needs to straighten the handrail fixed with the GPS. If the handrail is slightly tilted, the GPS data check will be deviated, affecting the subsequent topographic measurement. Based on this, a GPS auxiliary device for engineering surveying and mapping is provided. Utility Model Content

The top block 2052 and the bottom block 2053 are respectively fixed to the upper and lower ends of the support column 2051. The support column 2051 is vertically slidably connected to the inner side of the through hole 204.

[0039] When the column 101 is placed upright on the ground, the top block 2052 is in contact with the ground, and the anti-dumping member 205 as a whole automatically adjusts its height according to the ups and downs of the ground;

[0040] The self-locking unit 206 includes an I-shaped slider 2061, a clamping block 2063, and a W-shaped spring piece 2064;

[0041] A horizontal slide groove 210 is formed at the top of the connecting arm 202 and extends to the bottom of the connecting arm 202. The horizontal slide groove 210 and the through hole 204 are aligned along the straight line of the connecting arm 202.

[0042] The I-shaped slider 2061 is horizontally slidably connected to the horizontal slide groove 210 and protrudes to the upper and lower ends of the connecting arm 202. The clamping block 2063 is fixed to one end of the top of the I-shaped slider 2061 and clamped to the inner side of an annular clamping groove 2054 to achieve the initial positioning of the height of the support column 2051.

[0043] The W-shaped spring piece 2064 is bonded and fixed to the middle of one end of the I-shaped slider 2061, and the other end of the W-shaped spring piece 2064 is attached to the inner wall end surface of the horizontal slide groove 210, so as to provide a thrust for the I-shaped slider 2061 toward the support column 2051;

[0044] The locking unit includes a heavy pressure seat 207, a connecting cylinder 208, and a hand-held ring block 209;

[0045] A trapezoidal pressing block 2062 is fixedly connected to the top of the I-shaped sliding block 2061;

[0046] The heavy pressure seat 207, the connecting column 208, and the hand-held ring block 209 are fixed and slidably sleeved on the outer side of the column 101 in sequence from bottom to top. The heavy pressure seat 207 is located above the fixed ring block 201. The trapezoidal pressure block 2062 is squeezed by the heavy pressure seat 207 to keep the I-shaped slider 2061 close to the support column 2051.

[0047] The outer side of the column 101 is located above the hand-held ring block 209 and is fixedly connected to a limiting circular block 105 for providing a limit for the upward movement of the hand-held ring block 209 .

[0048] In this embodiment: when the measuring body 1 is in use, the hand can hold the hand-held ring block 209, and then lift the device as a whole. At this time, the hand-held ring block 209, the connecting cylinder 208, and the heavy pressure seat 207 will move upward relative to the column 101. The hand-held ring block 209 fits with the limiting circular block 105, and the bottom of the heavy pressure seat 207 is separated from the trapezoidal pressure block 2062, and the pressure on the trapezoidal pressure block 2062 is released at this time;

[0049] At the same time, the anti-dumping member 205 will slide downward to the lowest point under its own weight (it should be noted that the top block 2052 and the bottom block 2053 are used to limit the up and down movement of the support column 2051, and the end surface of the clamping block 2063 in contact with the annular clamping groove 2054 is an arc surface, so the anti-dumping member 205 can squeeze the clamping block 2063 to shrink), and then the device is placed upright at the designated position as a whole, and the bottom of the bottom block 2053 will also contact the surrounding ground at the designated position, and the anti-dumping member 205 will move upward under the squeezing force of the ground;

[0050] When the cone at the bottom end of the column 101 touches the ground, after determining that the column 101 is in a vertical state, the handle ring block 209 is pushed to apply a downward thrust, so that the handle ring block 209, the connecting column 208, and the heavy pressure seat 207 move downward as a whole, and the heavy pressure seat 207 moves downward to squeeze the trapezoidal pressure block 2062, so that the clamping block 2063 and the annular clamping groove 2054 maintain a stable clamping state;

[0051] At this time, if the column 101 tends to tilt, the anti-dumping member 205 in the tilting direction will be squeezed by the ground and move upward. At this time, the anti-dumping member 205 is locked by the clamping block 2063 and cannot move. Therefore, the column 101 can be prevented from tilting, ensuring the stability of the upright state of the column. In addition, during this process, the hand will also receive a reaction feedback, which is also convenient for the operator to discover the tilting trend of the column 101, so as to adjust the force applied to the column 101 in time.

[0052] Please refer to Figures 1 to 3 , the through holes 204, the anti-dumping parts 205, the self-locking units 206, and the horizontal slide grooves 210 are provided in multiple groups and distributed in a ring shape;

[0053] The end surfaces of the multiple trapezoidal pressing blocks 2062 in the multiple groups of self-locking units 206 close to the column 101 are in an inclined structure, and the bottom of the heavy pressure seat 207 is in a conical structure.

[0054] In this embodiment: by setting up multiple groups of anti-dumping members 205, it can be in contact with the surrounding ground at a designated position, thus providing support for the column 101 in multiple directions, ensuring the upright stability of the column 101;

[0055] The bottom conical surface of the heavy pressure seat 207 cooperates with the inclined surface of the trapezoidal pressure block 2062 to better apply pressure.
