Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

As shown in fig. 1-2: the embodiment is a marker post for engineering measurement, which comprises a bearing disc 1, a lifting rod body 2 and three adjusting supports 3, wherein the lifting rod body 2 comprises a hollow outer sleeve rod 21 with an open top and a lifting screw rod 22 with a bottom end in threaded connection with the inner wall of the outer sleeve rod 21, and the outer sleeve rod 21 is vertically arranged at the center of the top of the bearing disc 1; evenly be provided with three notch along the outer disk body that bears dish 1, adjust support 3 and include hollow column's last support body 31 and lower support body 32 and set up the supporting legs 33 in support body 32 bottom down, the top of lower support body 32 is provided with the screw rod 34 that extends to in the support body 31, the screw hole that supplies screw rod 34 to alternate is seted up to the bottom of going up support body 31, screw rod 34 alternates the screw hole then with last support body 31 threaded connection, inwards sunken being formed with concave ring 35 on the cylinder of lower support body 32, the last support body 31 of three regulation support 3 corresponds respectively and extends to in three notch and with bear dish 1 articulated being connected.

Referring to fig. 1, a help disc 4 is provided around the top end of the lifting screw 22.

Referring to fig. 2, a sliding plate 36 is disposed on the top of the screw 34 in the upper frame 31, and is attached to the inner wall of the upper frame 31 and slides relative to the inner wall.

Referring to fig. 1, a through groove 23 is formed in the upper half rod body of the lifting screw 22, and a calibration cone 24 is hung in the through groove 23.

Referring to fig. 1, a reflective positioning column 5 is arranged on the top of the lifting screw 22.

In practical application, the three adjusting supports 3 hinged with the bearing disc 1 are outwards supported, then the lower frame body 32 of the corresponding adjusting support 3 is rotated according to practical working conditions, the screw 34 on the lower frame body 32 drives the lower frame body 32 to extend downwards or contract upwards to adjust the telescopic length when the lower frame body 32 rotates, and the lifting type marker post 2 is adjusted to be in a vertical state under the calibration reference of the calibration cone 24; when the height of the lifting mark post 2 needs to be increased, the rotation-assisted disc 4 is rotated to drive the lifting screw 22 to rotate upwards in the outer loop bar 21.

After the use, the lifting screw 22 is retracted into the outer loop bar 21 by reversely rotating the auxiliary rotating disc 4, then the three adjusting supports 3 are rotated upwards to be vertical, then the lower frame body 32 is rotated to be retracted to abut against the upper frame body 31, and then the rope is tied up through the concave ring 35, so that the operation is convenient, and the occupied space can be effectively reduced.
