CN2390180Y - Quick accurate leveller - Google Patents

Abstract

The utility model relates to a levelling instrument with quick and accurate measure, which is composed of a holder of the levelling instrument, a seat cover plate, a transparent looping communicating pipe filled with dark displaying liquid, and two transparent displaying plates with digital scales. When the levelling instrument is used, the smooth bottom surface of the holder of the levelling instrument is placed in a measured position of a measured object, and the levelling instrument can measure whether the measured position is in a horizontal position or not according to the height difference of displaying liquid displayed from the back of the two transparent displaying plates. The levelling instrument has high measurement accuracy, convenient observation to show values during measure and quick judgment and conclusions. The leveling instrument can be used for the level measurement of construction work of buildings, traffic, water conservancy, etc. and can be used for the slope measurement of construction work.

Description

Measure level rapidly and accurately

The utility model relates to the level that a kind of using liquid is measured levelness or degree of tilt, and particularly a kind of measurement is level rapidly and accurately.

The existing surveyor's staff that is widely used in the construction works such as building, traffic, water conservancy is observed levelness or the degree of tilt of judging measured object by a liquid water shift position on schedule in the middle of the ruler.Because the design of ruler self structure is unreasonable, make that the size as if some position has deviation slightly when making ruler, the position of perhaps putting in actual measurement is unreasonable, all might influence the accuracy of whole measurement result.And the seizure on schedule of this liquid water is observed inconvenient, time-consuming, so that the speed that judgement is obtained a result always dislikes unhappy

The purpose of this utility model is that a kind of measurement level accurately and rapidly is provided.

Solution of the present utility model is as follows.It has a bottom surface and all very smooth level seat of front end face, inwardly offers a trend from the front end face of level seat and is

The back-shaped connectivity slot of the symmetry of shape, the bottom of back-shaped connectivity slot parallels with level seat bottom surface, left part and right part are all perpendicular with level seat bottom surface, top is height of center and two ends are low slightly, in this back-shaped connectivity slot, tightly be equipped with a transparent back-shaped communicating pipe, encapsulating in transparent back-shaped communicating pipe and highly be lower than its left part and right part top and be higher than its left part and the dark colour of right part bottom demonstration liquid, installing is fixed with a flap plate that transparent back-shaped communicating pipe is covered on level seat front end face, transparent back-shaped communicating pipe left part and the flap plate in right part dead ahead on offer the display window of equal height respectively, in these two display windows, tightly setting respectively and have the transparent display board that same numbers scale and the height of these same numbers scales from level seat bottom surface also all equate respectively.

The utility model with said structure is when concrete the use, the bottom surface that it is smooth places the tested place of measured object, if from left and right two transparent display boards show later transparent back-shaped communicating pipe left part with right part in when showing that the height of liquid is identical, the tested place that measured object then is described is the position that is in abswolute level; And when if the demonstration liquid height that two transparent display boards show later has difference, the tested place that measured object then is described is in non-level position, head height that displayed value is bigger is described promptly and less one of displayed value is low, and be to show that difference is big more, the difference of height that tested place two position height then is described is just big more, or the degree of tilt at tested place is big more.

Accuracy of measurement height of the present utility model, it is convenient to observe displayed value when it is measured, and judges and draws a conclusion fast.It also can be used for the slope measuring in the engineering construction except that doing the measurement of the level.

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 1 and Fig. 2 are respectively front elevation of the present utility model and vertical view;

Fig. 3, Fig. 4 and Fig. 5 divide other to be the A-A of Fig. 1, B-B and C-C cut-open view;

Fig. 6 is the D-D cut-open view of Fig. 3.

Referring to Fig. 1 to Fig. 6, the utlity model has all very smooth level seat 1 of a bottom surface 11 and front end face 12, inwardly offer a trend from the front end face 12 of level seat 1 and be

The back-shaped connectivity slot 13 of the symmetry of shape, the bottom of back-shaped connectivity slot 13 parallels with the bottom surface 11 of level seat 1, left part and right part are all perpendicular with the bottom surface 11 of level seat 1, top is height of center and two ends are low slightly, in this back-shaped connectivity slot 13, tightly be equipped with a transparent back-shaped communicating pipe 2 made from glass material, encapsulating in transparent back-shaped communicating pipe 2 and highly be lower than its left part and right part top and be higher than its left part and the dark colour of right part bottom shows liquid 3, dark colour shows that liquid 3 adopts red water liquid in an embodiment.A flap plate 4 that transparent back-shaped communicating pipe 2 is covered in is adhesively fixed on level seat 1 front end face 12, transparent back-shaped communicating pipes 2 left part and the flap plate 4 in right part dead ahead on offer the display window of equal height respectively, in these two display windows, tightly setting respectively and having same numbers scale 51 and 61 and the transparent display board 5 and 6 that also all equates respectively from the height of level seat 1 bottom surface 11 of these same numbers scales 51 and 61, transparent display board 5 and 6 can adopt the transparent organic glass material to make, and they can bondingly be embedded in the display window on the flap plate 4.Level seat 1 of the present utility model and flap plate 4 all can adopt timber or plastics.
