Abstract

The utility model relates to a measuring tape which can prevent the offset and ensure the measuring linearity. The measuring tape comprises a shell, a winding barrel and a ruler, wherein a slot is arranged at the lower end of the surface of the shell, a winding barrel is rotatably arranged in the shell, the ruler is wound on the winding barrel in a rolling way and extends out of the slot, the shell is provided with a top part, a head part, a bottom wall, a left lateral wall and a right lateral wall, and an end hook which exposes out of the slot is arranged at one end of the ruler. The measuring tape is characterized in that rotatable position legs are arranged at the lateral walls of the shell near the bottom wall, preferably, the rotatable positioning legs are symmetrically arranged at two sides of the shell, and the left wall and the right wall are respectively provided with two rotatable positioning legs. As the positioning legs can support against one side of an object to be cut, the offset in the measuring (and/or cutting) process is prevented, and the measuring (and/or cutting) linearity is ensured.

Description

Tape measure

Technical field

The utility model relates to a kind of tape measure, relates in particular to a kind of tape measure that can prevent the linearity of skew, assurance measurement (and/or cutting).

Background technology

Tape measure has become one of instrument of a lot of industry staff's indispensabilities as a kind of survey instrument commonly used.Usually, tape measure comprises housing, around tube and chi bar, has a line of rabbet joint in the surperficial lower end of housing, rotatably is installed in the housing around tube, and an end of chi bar has end hook, and this end hook is exposed to the outside of the line of rabbet joint.The pulling end hook, the chi bar can stretch from housing by the line of rabbet joint.During measurement, an end of chi bar is fixed in the initiating terminal of measured object bulk measurement by end hook, and the pulling tape measure can be measured object being measured to the measurement length place that needs.But, when object being measured is longer, usually can not guarantee the linearity measured, also influenced the carrying out of subsequent operation (as cutting) to object being measured.

Summary of the invention

The utility model aims to provide a kind of tape measure that can prevent the linearity of skew, assurance measurement (and/or cutting) at the deficiencies in the prior art.

For this reason, the technical scheme that the utility model adopted is: a kind of tape measure, comprise a housing that has a line of rabbet joint in surperficial lower end, one be rotatably mounted in the described housing around tube and one with web-like around the described chi bar that on tube and by the described line of rabbet joint, stretches out, described housing has top, head, diapire and left and right sides sidewall, one end of described chi bar has the end hook that is exposed to the line of rabbet joint, it is characterized in that: be provided with rotatable angle in described housing sidewall near the diapire place.

Described rotatable angle is arranged on the left and right sides sidewall of housing symmetrically.

The quantity of described rotatable angle is each two of left and right sides sidewalls.

As a kind of optimization of the present utility model, has a panel vertical at tape measure away from an end of the line of rabbet joint with shell bottom wall, has a visual reading window in described case top, this visual reading window has an index line, and the indicated length value of index line is the horizontal range at chi bar end hook place to tape measure panel place.

As preferably, described panel is provided with the bonding jumper more than two or two, and this bonding jumper is slightly above the plane at panel outer surface place.As further preferred, described bonding jumper is the magnetic conductive metal bar, and in the interior survey of described panel, is close to this magnetic conductive metal bar some magnetic patch are installed.As optimum, described magnetic conductive metal bar is a steel bar, and quantity is two, and is arranged at the left and right sides of described panel symmetrically; Described magnetic patch is six, and is close to described steel bar symmetry equally spacedly and installs.

As another kind of optimization of the present utility model, described housing be shaped as the waist type that meets ergonomics.

Compared with prior art, the utility model is owing to be provided with rotatable angle on sidewall, one side of that this angle can lean against is measured (and/or cutting) object has prevented the skew in measurement (and/or cutting) process, has guaranteed the linearity of measurement (and/or cutting).

Have a panel vertical when having adopted, and when described case top had the prioritization scheme of a visual reading window, the length of object being measured can be read from this window directly with shell bottom wall; And owing to have a panel vertical with shell bottom wall, when needs carry out perpendicular cuts to object being measured, only need that cutting tool (as saw) is close to this panel cutting and get final product, guaranteed the verticality of cutting, and can directly carry out perpendicular cuts by needed length this object.

In addition,, meet very much the natural structure of staff, use as snug as a bug in a rug, nature because the shape of tape measure housing has adopted the waist type that meets ergonomics.

Embodiment

Below in conjunction with accompanying drawing preferred implementation of the present utility model is described in further detail.Will be to part same as the prior art in the utility model with reference to prior art.

Fig. 1 shows the tape measure of preferred implementation of the present utility model, comprises a housing 1, and this housing 1 comprises head 11, top 12, diapire 14 and left and right sides sidewall 13.Head 11 lower ends at housing 1 are formed with a line of rabbet joint (not shown) near diapire 14 places, rotatably be installed in the housing 1 around the tube (not shown), around stretching out on tube and by the described line of rabbet joint, an end of chi bar 2 has the end hook 21 that is exposed to the line of rabbet joint to chi bar 2 with web-like.

Sidewall 13 at tape measure housing 1 is provided with rotatable angle 5 near diapire 14 places.In the present embodiment, this rotatable angle 5 is arranged on the left and right sides sidewall 13 symmetrically, two of every sides.As shown in Figure 1 and Figure 2, this rotatable angle 5 is installed on the housing 1 with buckle structure, during use, rotatable angle 5 is screwed off, vertical with the diapire 14 of housing 2, angle 5 is near a side of measured (and/or cutting) object 6, thereby guaranteed the linearity of measurement (and/or cutting), prevented skew; When not using, angle can be regained.Fig. 9 shows and uses the linearity of tape measure to keep measuring with this angle 5.

Shown in Fig. 3,5,6,7,8, has a panel 3 vertical away from an end of the line of rabbet joint with the diapire 14 of housing 1 at tape measure.This panel 3 is installed on the tape measure by buckle structure.Panel 3 is provided with two steel bars 31, and this steel bar 31 is installed on the left and right sides of panel 3 symmetrically by the steel bar groove 33 of panel inboard, and the one end is slightly above the outside surface of panel 3; The inboard of panel 3 is close to steel bar 31 six magnetic patch 32 is installed equally spacedly, and this magnetic patch 32 is installed on the panel 3 by the magnetic patch groove 34 of panel inboard.

As shown in Figure 3, Figure 4, has a visual reading window 4 at the top 12 of tape measure housing 1.This visual reading window 4 has an index line, and the indicated length value of this index line is the horizontal range Ls of chi bar end hook 21 places to the outer surface of tape measure panel 3.In the present embodiment, when the end hook 21 of chi bar 2 was positioned at line of rabbet joint place, the indicated length value of visual reading window 4 index lines was 16 centimetres, and promptly tape measure line of rabbet joint place to the horizontal range of the outside surface of panel 3 is 16 centimetres.
