Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
A kind of accurate levelling instrument, comprise chi body 10, chi body bottom surface 16, magnetic attracting device 13, magnetic attracting device 13 is positioned at the inner side of chi body bottom surface 16, and it also comprises left end cap 14, right end cap 15, surveys levelness system and survey vertical bury pipe system, and left end cap 14 and right end cap 15 are positioned at the both sides of chi body 10; Survey a left side that levelness system comprises the inner side being symmetricly set on left end cap 14 and right end cap 15 and mould glass-tube 701 and glass-tube 702 is moulded on the right side, glass-tube 701 is moulded on a left side and right top of moulding glass-tube 702 is communicated with by top hose 91 and bottom hose 92 respectively with bottom; Survey vertical bury pipe system and comprise spring 2, fine rule 3, prill 4, spring 2 and prill 4 are located at the inner side of left end cap 14 and right end cap 15 respectively, are connected between spring 2 and prill 4 by fine rule 3; Mould glass-tube 701 and the right side to mould glass-tube 702 and be respectively equipped with on a left side above and survey horizontal scale chi 81.Glass-tube 701 is moulded on a left side and glass-tube 702 in-built band look transparency liquid 71 is moulded on the right side, forms enclosed liquid linker, is kept flat by chi body after leaving standstill and can survey reading horizontal situation on horizontal scale chi 81.Before surveying horizontal scale chi 81, the front of square chi body 10 is respectively equipped with and surveys levelness window 12, to observe the liquid case moulded in glass-tube.
The front of chi body 10, position corresponding with end face are below respectively equipped with and survey vertical bury pipe window 11, be respectively equipped with in the inner side surveying vertical bury pipe window 11 and survey vertical bury pipe rule 82, judge vertical bury pipe to observe the swing situation of fine rule.
In the inner side of left end cap 14 and right end cap 15, be positioned at a left side and mould glass-tube 701 and right rear of moulding glass-tube 702 is fixed with U-shaped sheet metal 1 and Spring Card 5 respectively, spring 2 and prill 4 is respectively equipped with in U-shaped sheet metal 1 and Spring Card 5, Spring Card 5 effect is to block prill 4 when not measuring, and again plastic beads is taken out and loosens fine rule in draw-in groove can measure vertical bury pipe when surveying vertical bury pipe.Be provided with draw-in groove 61 in the outside of right end cap 15, be provided with plastic beads 6 in draw-in groove 61, plastic beads 6 is connected with prill 4 by line 41.
In present embodiment, the diameter of top hose 91 and bottom hose 92 is 1-2mm.Mould flow velocity between glass-tube with confined liquid two, to eliminate rocking of liquid, so that Quick Measuring goes out level, simultaneously when liquid stream to want during balance can the liquid segment in small hose above and below air in small hose fully catch up with only, elimination measure error.The diameter of prill 4 is 8 ~ 12mm, and the diameter of plastic beads (6) is 3 ~ 5mm.
Embodiment 1
.distance between horizon rule two scale manufactured is 600mm, and scale spacing is 1mm.Chi body is printed on corresponding " scale-gradient " table of comparisons.
When surveying levelness, when being horizontally placed on measured object by horizon rule, the fenestella can moulding glass-tube front from two ends is observed respective height of liquid level and reads difference.If both sides liquid level is the same, then illustrate that object is level.
Below chi body, magnetic attracting device 13 is equipped with on both sides, can be adsorbed on ironware.
When surveying vertical bury pipe, chi body left end being rotated up 90 degree of settings leans against on measured object, plastic beads (6) is taken out in draw-in groove 61, under the effect of spring 2 being in the other end, prill under gravity straight down, pull-out in Spring Card 5, namely prill falls line and affranchises, can find out measured object forward from the position residing for survey vertical bury pipe window 11 observation line in chi body three faces pendant with vertical bury pipe that is side direction.Vertical bury pipe situation reads by surveying on vertical bury pipe rule 82, if fine rule 3 is in 0 scale place, then illustrates that object is vertical; If fine rule is to right avertence 1 scale, then can check in from the table of comparisons gradient that top is tilted to the right is 0.095 degree=5.7 '=0.16 gradient (gradient principle when surveying levelness herewith).
During accident vertical bury pipe, the pendant line of band prill is pulled outwardly, prill is stuck in Spring Card, then plastic beads is stuck in draw-in groove, in case prill smashes other component in chi body.
