Description

A kind of tape measure

Technical field

The utility model relates to a kind of tape measure, relates in particular to a kind of tape measure of being convenient to object being measured is carried out perpendicular cuts.

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.During measurement, pull out end hook, the chi bar stretches from housing by the line of rabbet joint, can measure object being measured.Existing tape measure, function ratio is more single, when needs carry out perpendicular cuts to object being measured, generally is first marking around object being measured, cuts according to mark line, and this way is not only loaded down with trivial details, and usually can not guarantee the verticality of cutting.

Summary of the invention

The utility model aims to provide a kind of tape measure of being convenient to object being measured is carried out perpendicular cuts at the deficiencies in the prior art.Another purpose of the present utility model provides a kind of tape measure with visual reading window.

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: have a panel vertical with shell bottom wall at tape measure away from an end of the line of rabbet joint.

As a kind of optimization of the present utility model, described panel is provided with the bonding jumper more than two or two, and this bonding jumper is slightly above panel outer surface.As preferably, 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 further preferred, 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, 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 another optimization of the present utility model, be provided with rotatable angle near the diapire place in described housing sidewall.As preferably, described rotatable angle is arranged at the left and right sides sidewall of housing symmetrically; As further preferred, the quantity of this rotatable angle is each two of left and right sides sidewalls.

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

Compared with prior art, the utility model, only needs that cutting tool (as saw) is close to this panel cutting and gets final product when needs carry out perpendicular cuts to object being measured owing to be provided with a panel vertical with shell bottom wall, both simple and easy to do, can guarantee the verticality of cutting again.

When the bonding jumper that is provided with on the panel slightly above panel outer surface,, has the function of protecting panel because this bonding jumper can prevent the friction of cutting tool and panel; When having adopted the preferred version of magnetic conductive metal bar and magnetic patch, the magnetic conductive metal bar is by the magnetic of conduction magnetic patch, and absorption iron and steel class cutting tool has further guaranteed the verticality of cutting.

When having adopted the prioritization scheme with visual reading window, the length of object being measured can directly be read from this window, and can directly carry out perpendicular cuts to this object by needed length.

When having adopted the preferred version with rotatable angle, this angle can lean against a side of measured and/or cutting object, can prevent skew, guarantees the linearity of measuring and/or cutting.

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.

Tape measure has a panel 3 vertical with the diapire 14 of housing 1 away from an end of the line of rabbet joint.This panel 3 is installed on the tape measure by buckle structure.Shown in Fig. 1-5, 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 Fig. 1, shown in Figure 6, 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.
