Abstract

A level bar for plumber comprises a vertical level bubble, a horizontal level bubble, an upper reference surface, a lower reference surface and a rule body, etc. The level bar is different in that: the upper reference surface of the rule body is a plane and can be used to measure the planar part of a measured piece; and the width direction of the lower reference surface of the rule body is of a cambered structure and can carry out convenient and accurate measurement of a measured piece with cambered surface. Therefore, the level bar has simple structure and wide application, and is particularly suitable for a plumber to use during construction.

Description

A kind of pipeliner uses surveyor's staff

Technical field:

The utility model relates to a kind of surveyor's staff, and especially a kind of pipeliner uses surveyor's staff.

Background technology:

At present, two reference field majorities up and down of surveyor's staff are planes in the prior art.When needs are measured pipe or have arc measured piece surperficial, usually, make the stable not good enough of surveyor's staff, thereby influenced the degree of accuracy and the construction quality of measurement because the reference field of surveyor's staff is too little with the surface of contact of measured piece.

Summary of the invention:

The purpose of this utility model just provides can be convenient for measuring the measured piece that has curved surfaces, simple in structure, broad-spectrum a kind of pipeliner uses surveyor's staff.

The purpose of this utility model is achieved in that a kind of pipeliner uses surveyor's staff, comprise vertical air level, horizontal levelling bubble, last reference field, following reference field and chi body, it is characterized in that: the fixedly connected form of an end of chi body, the form internal fixation connects vertical air level; The fixedly connected holder in the centre of chi body, the fixedly connected horizontal levelling bubble of holder; The centre of chi body last reference field parallel to each other and following reference field have peep mouthful with under peep mouth; The last reference field of chi body is the plane, and the Width of reference field is an arc under the chi body.

The utility model compared with prior art has the following advantages: owing to adopted the last reference field of chi body is the plane, can be used for the measurement to place, measured piece plane; The Width of reference field is the structure of arc under the chi body, can make things convenient for, accurately measure the measured piece that has curved surfaces, thereby simple in structure, of many uses.

Description of drawings:

Figure is a concrete structure synoptic diagram of the present utility model;

Among the figure 1, vertical air level 2, form 3, holder 4, on peep mouthfuls 5, horizontal levelling bubble 6, go up reference field 7, down reference field 8, peep mouthfuls 9 down, the chi body

Embodiment:

As shown in the figure, a kind of pipeliner uses surveyor's staff, comprises vertical air level (1), horizontal levelling bubble (5), last reference field (6), following reference field (7) and chi body (9) etc.End fixedly connected one circular form (2) at rectangular-shaped chi body (9), form (2) internal fixation connects a columned vertical air level (1), the two ends of vertical air level (1) are respectively facing to last reference field (6) and following reference field (7), to be convenient for measuring the verticality of measured piece.At the centre of chi body (9) fixedly connected one secondary holder (3), the two ends of columned horizontal levelling bubble (5) are installed in respectively on the corresponding holder (3), horizontal levelling bubble (5) is perpendicular to vertical air level (1), to be convenient for measuring the levelness of measured piece.Have in the centre of chi body (9) last reference field (6) parallel to each other and following reference field (7) and to peep mouthful (4) and to peep mouthful (8) down, on peep mouthful (4) and peep partly whole hollow outs between mouthful (8) down, be beneficial to people's conveniently observation.The last reference field (6) of chi body (9) is the plane, can be used for the measurement to place, measured piece plane, and chi body (9) Width of reference field (7) down is an arc, can be used for the measurement to pipe or measured piece arcwall face.On the length direction of chi body (9), also be provided with master scale, to be used for linear measure longimetry to measured piece.

Claims

1, a kind of pipeliner uses surveyor's staff, comprise vertical air level (1), horizontal levelling bubble (5), last reference field (6), following reference field (7) and chi body (9), it is characterized in that: the fixedly connected form of an end (2) of chi body (9), form (2) internal fixation connects vertical air level (1); The fixedly connected holder in centre (3) of chi body (9), the fixedly connected horizontal levelling bubble of holder (3) (5); The last reference field (6) that chi body (9) is parallel to each other and the centre of following reference field (7) have peep mouthful (4) and under peep mouth (8).

2, a kind of pipeliner according to claim 1 uses surveyor's staff, it is characterized in that: the last reference field (6) of chi body (9) is the plane, and chi body (9) Width of reference field (7) down is an arc.
