Embodiment
A kind of levelling pole of being convenient to righting as shown in Figure 1, comprise main scale 1 and secondary chi 5, described secondary chi 5 is arranged on the front side of described main scale 1, the top of described secondary chi 5 is connected with the bottom of described main scale 1, main scale 1 is stretched out in the lower end of described secondary chi 5, on the left surface on described main scale 1 top or right flank, the first circular bubble 2 is installed, on the leading flank of described secondary chi 5 bottoms, the second circular bubble 6 is installed.
In conjunction with Fig. 2, the top of described secondary chi 5 offers the first mounting hole 9 and is arranged on the second mounting hole 10 of described the first mounting hole 9 belows, on described main scale 1, be provided with first threaded hole corresponding with described the first mounting hole 9 positions, on described main scale 1, be provided with second threaded hole corresponding with described the second mounting hole 10 positions.
Again in conjunction with Fig. 3, described main scale 1 and secondary chi 5 are by through the first mounting hole 9 and stretch into the first attachment screw 8 of described the first threaded hole and be connected through the second mounting hole 10 the second attachment screw 7 of stretching into described the second threaded hole.
As shown in Figure 4, described the first attachment screw 8 and the second attachment screw 7 include screw cap 8-1 and threaded shank 8-3, and for the 8-2 of polished rod portion of the 8-3 of connecting screw rod portion and screw cap 8-1, described threaded shank 8-3 is provided with screw tip 8-4 away from one end of screw cap 8-1.
In conjunction with Fig. 2, Fig. 3 and Fig. 4, the 8-2 of polished rod portion of described the first attachment screw 8 and the first mounting hole 9 are rotating, the 8-2 of polished rod portion of described the second attachment screw 7 and the second mounting hole 10 are rotating, described the second mounting hole 10 is square opening, and the upside hole wall 10-1 of described the second mounting hole 10 is the circular arc of rotating for the 8-2 of polished rod portion along the first attachment screw 8.
As shown in Figure 1, be provided with the first elastomeric pad 3 and the second elastomeric pad 4 between described main scale 1 and secondary chi 5, described the first attachment screw 8 passes successively the first mounting hole 9 and the first elastomeric pad 3 and extend in described the first threaded hole; Described the second attachment screw 7 passes successively the second mounting hole 10 and the second elastomeric pad 4 and extend in described the second threaded hole.
In the present embodiment, preferred way is that described the first attachment screw 8 and the second attachment screw 7 are integral structure.
In the present embodiment, when carrying out building subsidence observation, if hold up chi personnel can see the first circular bubble 2 on main scale 1, that just pulls down secondary chi 5; When observation station overhead higher, hold up the just hand steered bottom of living main scale 1 of chi personnel, and eyes are below main scale 1 bottom time, install secondary chi 5, and main scale 1 and secondary chi 5 are adjusted, so that the second circular bubble 6 on the first circular bubble 2 on main scale 1 and secondary chi 5 is synchronously adjusted.
Concrete, the synchronous set-up procedure of the first circular bubble 2 on described main scale 1 and the second circular bubble 6 on secondary chi 5 is: by the first attachment screw 8, with the second attachment screw 7, main scale 1 is connected with secondary chi 5, now secondary chi 5 can rotate around the 8-2 of polished rod portion of the first attachment screw 8, the 8-2 of polished rod portion on the second attachment screw 7 moves along the upside hole wall 10-1 of the second mounting hole 10, and then adjust secondary chi 5 at left and right directions, while being positioned at the middle part on left and right directions by the bubble on the second circular bubble 6, tighten the first attachment screw 8 and the second attachment screw 7 and then limit secondary chi 5 in the rotation of left and right directions, continue again to observe subsequently the bubble on the second circular bubble 6, elastic reaction due to the first elastomeric pad 3 and the second elastomeric pad 4, thereby can or screw out the first attachment screw 8 and precession or back-out the second attachment screw 7 by precession, and then complete the adjustment on fore-and-aft direction to secondary chi 5, the bubble and the bubble on secondary chi 5 second circular bubbles 6 that finally reach on main scale 1 first circular bubble 2 are all placed in the middle, and then reached the first circular bubble 2 and synchronizeed with the second circular bubble 6.
Next by this levelling pole, monitoring point is observed again, main scale 1 is alignd with monitoring point, a hand is held main scale 1, and now the second circular bubble 6 and the first circular bubble 2 synchronised, can reach the righting of levelling pole with the second circular bubble 6 on the secondary chi 5 of eye observation.This levelling pole is by arranging secondary chi 5, thereby realize a kind of extension to main scale 1, in the situation that guaranteeing that monitoring point is constant, by the 6 pairs of whole levelling poles of the second circular bubble that are arranged on secondary chi 5, carry out leveling, thereby facilitated operating personnel when naturally standing, just can be good at this levelling pole righting, avoid monitoring point too high, operating personnel cannot observe bubble, and then cause measuring error, greatly facilitate operating personnel's surveying work.
The above; it is only preferred embodiment of the present utility model; not the utility model is imposed any restrictions; every any simple modification, change and equivalent structure transformation of above embodiment being done according to the utility model technical spirit, all still belongs in the protection domain of technical solutions of the utility model.
