Abstract
The utility model relates to a tubular level which can be used on various leveling rods, centering instruments, setting instruments and other measurement instruments. The prior tubular levels having shells made of transparent organic glass contract and deform during the injection molding so that the defects that the inner arc shapes and sizes of the tubular levels are subject to deviation and the scale lines printed with oil ink are easy to fade and be abraded exist, so the utility model provides a tubular level with inner arc shape and size meeting the requirement of the standard and with scale lines which do not fade and are not abraded. The tubular level comprises a level shell, a level stopper, level filling liquid and a wire ring, wherein, the level shell is made of transparent material, the wall of an inner hole on the level shell takes the shape of an arc, the wall of the inner hole on the level shell is provided with a wire ring groove, the wire ring is retained in the wire ring groove on the wall of the inner hole, the level filling liquid is infused into the inner hole on the level shell, and the opening of the inner hole on the level shell is sealed by the level stopper.
Description
Technical field
The utility model belongs to the survey instrument technical field, particularly a kind of tube bubble that is used on the survey instruments such as all kinds of surveyor's staffs, levelling instrument, Anping instrument.
Background technology
It is existing that to be contained in the case material that is adopted on the survey instruments such as all kinds of surveyor's staffs, levelling instrument, Anping instrument be the tube bubble of transparent organic glass, the interior circular arc of its air level all is directly to make when injection moulding, air level delineation line stamps with printing ink, because can producing when injection moulding, shrinks and distortion in organic glass, make the shape and size of circular arc in the tube bubble produce deviation, and the delineation line that printing ink stamps also comes off easily and weares and teares, thereby has influenced precision, sensitivity and the outward appearance of air level.
Summary of the invention
The utility model is that the tube bubble of transparent organic glass can produce contraction and distortion at existing case material when injection moulding, make the shape and size of circular arc in the tube bubble produce the weak point that delineation line that deviation and printing ink stamps comes off easily and weares and teares, provide the shape and size conformance with standard requirement of circular arc in a kind of air level, the tube bubble that the delineation line in the air level can not come off and wear and tear.
The technical scheme that the utility model tube bubble adopts is finished in the following way: tube bubble comprises air level housing, bubble plug, air level filling liquid and silk ring, wherein, the material of air level housing is a transparent material, preferred material is a transparent organic glass, endoporus hole wall on the air level housing is circular-arc, the arc radius of endoporus hole wall is 6876mm～115mm, on the hole wall of endoporus, have an annular groove, silk encircles in the silk annular groove that is stuck on the endoporus hole wall, and the available steel wire of silk ring is made; In the endoporus on the air level filling liquid injection air level housing, the aperture of endoporus is sealed by the bubble plug on the air level housing.
The utility model tube bubble is compared with existing tube bubble, has good looking appearance, and air level delineation line can not come off, can not be worn, the precision of air level and highly sensitive characteristics.The utility model is particularly suitable as the tube bubble on the survey instruments such as all kinds of surveyor's staffs, levelling instrument, Anping instrument.
