Description
Technical Field
The utility model relates to a detect measuring tool, especially a bend radius dipperstick.
Background
In daily life, the bending radius of some objects needs to be measured, for example, in electrical construction, in order to ensure that a cable cannot be damaged or clamped due to the fact that the bending radius is too small in a protective sleeve, the bending radius of a wire casing is not less than 6 times of the outer diameter of a pipe, for example, a pipe of DN100, when the pipe is bent, the bending radius is not less than 6 x 100=600mm, and generally, a constructor can perform pipe bending according to construction experience, through visual observation, without verification, so that the operation easily causes the actual bending radius of the wire casing to be less than 600 mm.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a simple structure, bend radius dipperstick that can rapid survey.
The utility model adopts the following technical scheme:
a bending radius measuring scale comprises a scale body, wherein the scale body comprises a first scale and a second scale, one end of the first scale and one end of the second scale are respectively provided with a contact plate, an observation seam is arranged on the first scale, scale marks are arranged on the second scale, and the first scale and the second scale are connected through a positioning needle.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses simple structure, convenient preparation, the bending radius that can the rapid survey object has avoided workman's naked eye observation to cause the too big defect of error.
Further, the utility model discloses a preferred scheme is:
the first contact plate is perpendicular to the first ruler, and the second contact plate is perpendicular to the first ruler.
The scale of the scale mark is set to be 1 mm.
The first ruler and the second ruler are respectively steel plates with the width of 25mm and the thickness of 5 mm.
Drawings
FIG. 1 is an exploded view of various parts of the present invention;
FIG. 2 is a diagram illustrating the usage of the present invention;
in the figure: a ruler I1; observing the seam 101; a second ruler 2; scale lines 201; a positioning pin 3; a first contact plate 4; a second contact plate 5; an object to be measured 6.
Detailed Description
The invention is further described with reference to the following figures and specific embodiments.
Referring to the drawings: the utility model provides a bend radius dipperstick, includes the ruler body, the ruler body comprises ruler one 1 and ruler two 2, ruler one 1 and ruler two 2 are width 25mm respectively, the steel sheet preparation of thickness 5mm forms, ruler one 1 is provided with a penetrating observation seam 101 along its length, ruler two 2's up end is provided with a scale mark 201 that the scale interval is 1mm, 0 scale of scale mark 201 is arranged in ruler two 2 and is set up the one end tip of contact plate two 5 (as shown in figure 2), ruler one 1 and ruler two 2 pass through pilot pin 3 and connect. One end of the ruler I1 is vertically welded with a contact plate I4, and one end of the ruler II 2 is vertically welded with a contact plate II 5.
The utility model discloses utilize the tangent line perpendicular to of circle to cross the radius axiom of tangent point, the nodical promptly is the centre of a circle of the tangent point of two points on the circular arc, and the centre of a circle is the radius of asking promptly to the distance of circular arc.
When measuring, the first contact plate 4 is clamped on the inner side or the outer side of the measured object 6, the ruler 1 is ensured to be vertical to the measured object 6, then the second contact plate 5 is clamped on the inner side or the outer side of the measured object 6 corresponding to the first contact plate 4 (if the first contact plate is clamped on the inner side of the measured object, the second contact plate is also clamped on the inner side of the measured object), if the first contact plate is clamped on the outer side of the measured object, the second contact plate is also clamped on the outer side of the measured object), the first contact plate 4 and the second contact plate 5 need to be positioned on the same side of the measured object 6, the ruler 2 is ensured to be vertical to the measured object 6, then the positioning pin 3 is slid to an intersection point (as shown in fig. 2) where the two rulers intersect, and the bending radius of the.
The utility model discloses simple manufacture, the bend radius of acquireing testee 6 that can be quick to whether the bending that detects testee 6 is qualified.
The above is only the concrete embodiment of the present invention, but the protection of the present invention is not limited to this, and all the equivalent changes or replacements proposed to the technical features of the present technical solution, which can be thought by those skilled in the art, are covered within the protection scope of the present invention.
