Abstract

The utility model discloses a leveling instrument and is invested for solving the problem of the low precision of the leveling instrument in the prior art. The utility model comprises a leveling instrument body made of transparent material. The leveling instrument body is provided with a rectangular cavity and the cavity is filled with leveling instrument liquid. A scale indicator which can rotate freely along the length direction of the cavity is pivotally mounted in the cavity. A floating drift is mounted at the position near the head of the scale indicator; the scale of the inclination of the leveling instrument is arranged at the corresponding position to the scale indicator of the leveling instrument body; wherein, the buoyancy of the floating drift in the leveling instrument liquid is bigger than the weight of the scale indicator in the leveling instrument liquid. Using the structure, the scale indicator can always keep vertical with the help of the buoyancy of the floating drift and can indicate the scale well, thereby the indicating precision is improved greatly and the cost is lower than that of the electronic leveling instrument.

Description

Level

Technical field

The utility model relates to a kind of level.

Background technology

Common level is a sealed tube of being made by transparent material (glass, organic glass, plastics etc.), the less liquid of the coefficient of viscosity is housed in the sealing pipe, as alcohol, ether and mixture thereof etc., the part that has liquid at sealed tube or not is called leveling bubble usually.

This level is simple in structure, price is lower, so usable range is wider, on surveyor's staff, on the tripod that large size camera is used, electronic balance is first-class.But the pointing accuracy of this level is lower, and error is bigger, in some places that level is had relatively high expectations, then needs could judge by experience.Though and the level precision of some electrical type is higher, the higher environment for use of its cost requires comparatively harsh.

Summary of the invention

In order to overcome above-mentioned defective, the utility model provides that a kind of cost is low, pointing accuracy is higher, be convenient to operation, broad-spectrum level.

For achieving the above object, the utility model level, comprise the level body of making by transparent material, elongated cavity of this level body tool, in described cavity, be filled with level liquid, pivot is equipped with an energy and freely rotates division indicator along the cavity length direction in cavity in described cavity, be equipped with in the position of the nearly head of this division indicator one cursory; Be shaped on the scale of expression level degree of tilt on described level body with the corresponding position of division indicator, wherein, this cursory buoyancy in level liquid is greater than the weight of division indicator in level liquid.

Further, above-mentioned division indicator is a pointer, and wherein the afterbody of this pointer is installed in the cavity by one, the above-mentioned cursory position that is installed in the near pointer head.

Further, above-mentioned division indicator is two pointers, and these two pointer is corresponding, afterbody is coaxial, is installed in the cavity, the above-mentioned cursory position that is installed in nearly head between two pointers.

Further, above-mentioned division indicator is a segment, and the afterbody of this segment is installed in the cavity, and the above-mentioned cursory position that is installed in nearly covering of the fan top is shaped on Warning Mark on the segment.

After adopting said structure, division indicator is by cursory buoyancy, division indicator can remain vertical, and division indicator can be indicated scale preferably, so the big raising of pointing accuracy, and owing to be printed with scale on the level, so when measuring, also can measure angle of inclination accurately, easy operating, and it is lower to compare cost than electronic level, is convenient to promote.

Embodiment

Below in conjunction with accompanying drawing the utility model is described further.

Extremely shown in Figure 5 as Fig. 1, the utility model level, comprise the level body of making by transparent material 1, elongated cavity 2 of this level body tool, in described cavity 2, be filled with level liquid (not shown), pivot is equipped with an energy and freely rotates division indicator 3 along the cavity length direction in cavity in described cavity 2, is equipped with one cursory 4 in the position of these division indicator 3 nearly heads; Be shaped on the scale 5 of expression level degree of tilt on described level body with the corresponding position of division indicator, wherein, this cursory buoyancy in level liquid is greater than the weight of division indicator in level liquid.

Above-mentioned division indicator should select the lighter material of material to make, as plastics, aluminium etc.; Above-mentioned division indicator 3 can be various structures, and as depicted in figs. 1 and 2, it can be a pointer, and wherein the afterbody of this pointer is installed in the cavity by one, and one spherical cursory 4 is installed in the position of near pointer head; Also can be illustrated in figure 3 as two pointers, these two pointers are relative, and afterbody is coaxial, are installed in the cavity by one, and a cylindric cursory position that is installed in nearly head between two pointers can be observed comparatively accurately from positive and negative both direction like this; Can be a segment as Fig. 4 also, the afterbody of this segment be installed in the cavity by one, and the above-mentioned cursory position (not shown) that is installed in nearly segment top is shaped on a black triangle Warning Mark on the segment, so that accurately observation.

Above-mentioned cursory size and material shape can be according to the materials of division indicator, and size is selected.As being the plastics system bubble of various hollows, also can be the bigger material of various buoyancy and make, as light plastic etc.
