FIG. 2 is a cross-sectional view taken along line 1-1 of FIG. 1;

fig. 3 is the schematic diagram of the sighting rod for engineering survey of the present invention in the use state.

Labeled as: sighting mark pole body 1, straightness alignment display device 2 that hangs down, fixed subassembly 3, spirit level 4, locking bolt 5, fixed lantern ring 6, sighting mark 7.

Detailed Description

As shown in fig. 1, fig. 2 and fig. 3, the utility model provides a convenient operation, the fast sighting rod for engineering survey of finding. The sighting mark pole include sighting mark pole body 1, the sighting mark pole still include straightness alignment display device 2 that hangs down, the straightness that hangs down of sighting mark pole body 1 passes through in the use straightness alignment display device 2 that hangs down measure and show. This application is through increasing on the basis of current sighting mark pole body and setting up straightness alignment display device that hangs down to the straightness that hangs down that makes sighting mark pole body pass through in the use straightness alignment display device that hangs down measure and show. Like this, alright in order to need for carrying out the technical problem of straightness alignment that hangs down through operating personnel people among the effectual prior art that changes, guarantee the straightness requirement that hangs down of sighting mark pole in the use, simultaneously because the sighting mark pole is that the perpendicular alignment is realized through straightness alignment display device that hangs down fast, can also effectual improvement alignment fast, make alignment operation convenient more, swift.

In the above embodiment, the verticality alignment display device 2 may at least include two structures, one structure is that the verticality alignment display device 2 includes two sets of measuring weights with steel strands, the length of the steel strands is smaller than that of the sighting rod body 1, one end of the steel strands is connected with the corresponding measuring weights, the other end of the steel strands is detachably arranged at the top of two side surfaces of the sighting rod body 1, and the verticality of the sighting rod body 1 is measured and displayed by the distance from the two measuring weights located at the middle lower part to the sighting rod body 1 in the using process. The working principle is the principle of measuring the verticality of the conventional plumb line. The verticality alignment display device 2 with the structure has large measurement and display errors and is inconvenient to operate. Therefore, the application provides a verticality alignment display device 2 with another structure, namely the verticality alignment display device 2 comprises a fixing component 3 and a level 4, and the level 4 is detachably and fixedly arranged on the sighting mark post body 1 through the fixing component 3. The working principle is that the water bubble displays the level. In this case, the leveling device 4 is a circular leveling device. The verticality alignment display device 2 with the structure has the advantages of very simple structure, and very convenient installation, observation and display.

Furthermore, in order to facilitate the installation of the level, the fixing component 3 is a fixing lantern ring 6 with a locking bolt 5, the circular level is fixedly installed on the fixing lantern ring 6, and the fixing lantern ring 6 sleeved on the sighting mark pole body 1 is detachably locked on the sighting mark pole body 1 through the locking bolt 5.

The characteristics that the sighting mark pole body 1 among the combination prior art is mostly the square long and thin sighting mark pole of wooden or aluminum alloy matter, for more convenient observation and centering in use, this application is provided with respectively on two adjacent sides of the square long and thin sighting mark pole of wooden or aluminum alloy matter at least and follows length direction extension's sighting mark 7, in the alignment process, the vertical line of the cross on steel strand wires or the circular spirit level with sighting mark 7 coincide. Like this, in alignment process and use, as long as guarantee the cross on steel strand wires or the circular spirit level throughout the vertical line with 7 coincideings of sighting marking can guarantee the straightness that hangs down of sighting marking pole, especially when using circular spirit level, need the vertical line of its cross with 7 coincidences of sighting marking can, it is all very convenient to observe, use, has overcome among the prior art cross of the sighting device in a distant place need with the very inconvenient technical problem of operation of sighting marking coincidence on the marking pole.

In conclusion, the sighting mark post provided by the application also has the advantages that the sighting mark post can be adjusted through the observation level gauge, the sighting mark post is quickly vertical, the sighting mark post is quickly positioned through a vertical line on the observation instrument and a vertical sighting mark on the sighting mark post, the centering accuracy is high, the straightening and centering speeds are high, and the working efficiency is greatly improved.
