Abstract

The utility model provides a portable level measurer which is suitable for the fields of the industrial civil architecture, the industrial installation, etc. The portable level measurer makes use of a small level bar and a pull wire whose both ends are connected to obtain the measuring purposes. The utility model solves the inconvenient portability on the construction and other occasions. The utility model has the advantages of flexible operation, and low cost.

Description

Portable level measurer

The present invention relates to a kind of simple horizontal survey instrument, particularly a kind of portable horizontal survey instrument, it mainly is applicable to fields such as civil building and industry installation.

Because at present the length of the surveyor's staff that uses is a definite value, it is not only not portable, and can not bring into play its effect under some occasion, the horizontal survey when as point-to-point transmission barrier being arranged or be shorter than the concave surface horizontal survey etc. of surveyor's staff.And for example when the measured object surface irregularity, or when meeting the measurement of not dried cement flooring, the conventional levels chi needs just can finish with a lot of supplementary meanss, resembles with auxiliary stay with auxiliary scale etc., and these bring a lot of troubles to work undoubtedly.

The purpose of this invention is to provide a kind of low cost, portable horizontal checkout device that applicability is stronger.Be explained in detail below in conjunction with accompanying drawing.

The drawn sketch of a portable horizontal checkout device of accompanying drawing, wherein (6) are little surveyor's staffs, (2) be the bubble of indication level, backguy (8) penetrates two apertures (10) of pulling-on piece (9) and (11) latter two line end and penetrates in two joint terraced holes (3) (4) from the bottom of little surveyor's staff (6) and they can not be deviate from.Another root backguy (16) one ends penetrate in the aperture (15) on the pulling-on piece (12), and the other end penetrates in the terraced hole of joint (1) from the bottom of little surveyor's staff (6) and be fixing respectively.(5) (7) are two semi-circular chimbs of surveyor's staff (6) bottom, during work pulling-on piece (12) (9) is drawn back to two opposite directions, utilize marginal portion (17) (18) and (7) (5) that backguy (16) (8) is tightened, as long as backguy (8) (16) slightly contacts with measured object with the edge contact part of pulling-on piece (9) (12), can find out the result during measurement from bubble (2).Breach (14) (13) on the pulling-on piece (12) is that the length that is used for adjusting backguy (16) is used.Because little surveyor's staff (6) is near the backguy endpoint location, downward moment is very little, so as long as the power that has certain effect just can guarantee to measure in the backguy (8) (16).

This horizontal checkout body amasss very little, uses its not only singly only all right many coupling of use flexibly, for example; Just can get around barrier in the measurement with two parallel connections, three and with can once surveying a face, very low owing to price again, so practicality is very strong.

Accurate for what guarantee to measure, backguy (16) can not extend arbitrarily, serves as that easily backguy in addition (8) also should shorten as much as possible to be no more than 3 meters generally, and pulling-on piece (9) is got 2～3 centimetres to the distance of little surveyor's staff and got final product.Backguy (8) (16) should be selected lighter line such as Silk Threads, the nylon yarn etc. of same quality and thickness for use, and little surveyor's staff will be selected the high material of intensity in light weight such as bakelite, engineering plastics etc. for use.

Claims

1, a kind of portable horizontal checkout device, its technical characterictic are that little surveyor's staff [6] two ends are connected with backguy [8] [16] and pulling-on piece [9] [12].
