Abstract

The utility model relates to a pointer type level ruler which comprises a ruler body, wherein dials are respectively arranged at both ends of the ruler body, pointers are arranged on the dials, the pointers can rotate around the center lines of the dials, and magnets are arranged at the bottom surface of the ruler body. When the pointer type level ruler is used, the level ruler is put on a measured surface, when the measured surface is level, the level ruler is in a level state, and under the action of gravity, the pointers are in a vertical state and point to the zero positions of the dials;and when the measured surface is inclined, because the pointers are always in the vertical state, under the action of gravity, the pointers rotate by a certain angle and point at the corresponding degrees of the dials, thus the inclination of the measured surface can be read out conveniently from the dials. The pointer type level ruler has visual readings, high measuring accuracy and low measuringerror. When the measured piece is a metal piece, the level ruler can be adsorbed on the measured surface by the magnets which are arranged on the bottom surface of the ruler body. The pointer type level ruler is very convenient in use when being used for measuring vertical surfaces and inclined surfaces, and the universality of the level ruler is increased.

Description

The pointer-type surveyor's staff

Technical field

The utility model relates to a kind of horizontal survey instrument, relates to a kind of pointer surveyor's staff specifically.

Background technology

At present, the surveyor's staff that uses on occasions such as location setting-out, building decoration construction, equipment installation, machining mostly is bubble formula surveyor's staff greatly, its structure is on the chi body of surveyor's staff glass tube to be installed, be provided with the mercury bubble in the glass tube, during use, bubble formula surveyor's staff is placed on by on the side, judges the flatness of tested surface by the deviation position of observing the mercury bubble.

Bubble formula surveyor's staff is simple in structure and convenient in use, but also exists the shortcoming of following aspect: the one, and function singleness uses limitation big, except external other aspects of flatness of proofreading and correct testee are difficult to be employed; The 2nd, judge flatness by the position of observing the mercury bubble, directly reading is directly perceived inadequately, is easy to generate error; The 3rd, it is big to be affected by the external environment, and in the environment of comparatively complicated workplace or illuminance deficiency, the position that is difficult to see clearly the mercury bubble is easy to generate the bigger collimation error, and measuring accuracy is reduced.

Existing surveyor's staff is when measuring, only be that surveyor's staff is placed on the tested surface, surveyor's staff is easy to slide when being subjected to external force, thereby the measurement data precision is reduced, in addition, existing surveyor's staff need be fixed on surveyor's staff on the tested surface with hand when measuring vertical face and dip plane, hand can not the leaving water leveling ruler, brings a lot of inconvenience to work.

The utility model content

Problem to be solved in the utility model is at above problem, provides a kind of measuring accuracy height, measuring error is little, versatility good, pointer surveyor's staff easy to use.

For addressing the above problem, the technical scheme that the utility model adopted is: pointer surveyor's staff comprises the chi body, described chi body two ends are respectively arranged with index dial, described index dial is provided with pointer, and described pointer can rotate around the center line of index dial, and described chi body bottom surface is provided with magnet.

A kind of concrete prioritization scheme, described index dial can rotate around its center line.

A kind of concrete prioritization scheme, described magnet are bar magnet.

A kind of concrete prioritization scheme, the quantity of described magnet are four.

A kind of concrete prioritization scheme, described chi body is provided with the fixedly screw of index dial.

A kind of concrete prioritization scheme, described chi body is provided with scale value.

The utility model is taked above technical scheme, have the following advantages: in use, surveyor's staff is placed on by on the side, when by the side level, surveyor's staff is in horizontality, and under action of gravity, pointer is in vertical state, the zero degree place of pointed index dial, when tested surface tilts, because pointer always is in vertical state, so, under action of gravity, pointer will turn an angle, and pointer refers to the corresponding number of degrees place at index dial, like this, by the degree of tilt of side is exactly the number of degrees of pointer indication on index dial, the degree of tilt of tested surface can be read from index dial very easily, and reading is directly perceived, the measuring accuracy height, measuring error is little, when being metalwork, can surveyor's staff be adsorbed on by on the side by the magnet that is arranged on the chi body bottom surface, when measuring vertical face and dip plane by the side part, very easy to use, strengthened the versatility of surveyor's staff.

The utility model is described in further detail below in conjunction with drawings and Examples.

Description of drawings

Accompanying drawing 1 is the structural representation of pointer surveyor's staff among the utility model embodiment;

Accompanying drawing 2 is the upward view of accompanying drawing 1.

Among the figure: 1-chi body; The 2-index dial; The 3-pointer; The 4-screw; 5-magnet.

Embodiment

Embodiment: as shown in Figure 1, the pointer-type surveyor's staff, comprise chi body 1, chi body 1 two ends are respectively arranged with index dial 2, and index dial 2 can rotate around its center line, index dial 2 is fixedlyed connected with chi body 1 by screw 4, index dial 2 is provided with pointer 3, and pointer 3 can rotate around the center line of index dial 2, and chi body 1 bottom surface is provided with groove, be provided with magnet 5 in the groove, chi body 1 is provided with scale value.

The material of chi body 1, index dial 2 and pointer 3 is a stainless steel, makes surveyor's staff have higher resistance to abrasion and corrosion resistance, and when measuring, measures the influence that numerical value is not subjected to magnetic force.

As shown in Figure 2, magnet 5 is bar magnet, and the quantity of magnet 5 is four.

In use, surveyor's staff is placed on by on the side, and when by the side level, surveyor's staff is in horizontality, under action of gravity, pointer 3 is in vertical state, and pointer 3 points to the zero degree place of index dial 2, when tested surface tilts, because pointer 3 always is in vertical state, so under action of gravity, pointer 3 will turn an angle, the corresponding number of degrees place that pointer 3 refers at index dial 2, like this, be exactly the number of degrees of pointer 3 indication on index dial 2 by the degree of tilt of side, the degree of tilt of tested surface can be read from index dial very easily, reading is directly perceived, the measuring accuracy height, measuring error is little, when being metalwork by the side part, can surveyor's staff be adsorbed on by on the side by the magnet 5 that is arranged on chi body 1 bottom surface, when measuring vertical face and dip plane, very easy to use, strengthened the versatility of surveyor's staff.

In use, can as required screw 4 be unclamped, index dial 2 is rotated to appointed positions after, again screw 4 is being tightened, index dial 3 is fixedlyed connected, and then to being measured by the side with chi body 1.
