Description

A dipperstick for municipal drainage pipe is used

Technical Field

The utility model relates to a dipperstick, especially a dipperstick for municipal drainage pipe uses.

Background

When surveying underground pipeline, need to get the socle of pipeline, the pipe head and confirm the pipe diameter, all go to measure through a straight measuring tape among the prior art, when measuring, from the well head be difficult to the accurate position of accurate resolution socle and socle occasionally, have sight slope and sight to shelter from the condition moreover, lead to measuring accurate position not.

SUMMERY OF THE UTILITY MODEL

The technical task of the utility model is to the not enough of above prior art, and provide a dipperstick that is used for municipal drainage pipe to use.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a dipperstick for municipal drainage pipe is used, includes scale and reference scale, wherein the top of scale is equipped with the level bubble, the bottom of scale with the end of reference scale sets up perpendicularly the tow sides of scale all are equipped with the scale, and the lower that is located positive zero scale and standard ruler is in same horizontal position, and the highest that is located the zero scale at the back and standard ruler is in same horizontal position.

Further improvement: the graduated scale comprises a fixed rod and a movable rod, a sliding groove is arranged in the fixed rod, a sliding block matched with the sliding groove is arranged at the bottom of the movable rod, and the leveling bubble is located at the top of the movable rod.

Further improvement: the bottom of scale pass through the torsional spring with the reference scale is connected the bottom of scale is equipped with the stopper, the bottom surface of stopper with the scale is perpendicular.

Further improvement: the top surface of the front end of the reference ruler is provided with an inclined surface, the bottommost part of the inclined surface is provided with a roller, and when the reference ruler is in a horizontal state, the highest point of the roller is lower than the top surface of the reference ruler.

Further improvement: the top surface and the bottom surface of the reference ruler are both cambered surfaces.

The utility model has the advantages that: firstly, simple structure reads numerical value through the front of scale when the scale is in the bottommost of pipeline, reads numerical value through the back of scale when the scale is in the topmost of pipeline, and the difference of two last numerical values both is the diameter of pipeline, and this not only operates simple and conveniently, but also portable designs into telescopic with the scale to satisfy the measurement demand of the different degree of depth.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings.

As shown in the drawing, a dipperstick for municipal drainage pipe uses, includes scale and reference scale 8, wherein the top of scale is equipped with level bubble 4, the bottom of scale with the end perpendicular setting of reference scale 8 the tow sides of scale all are equipped with the scale, and the zero scale that is located the front is in same horizontal position with the lowest of reference scale 8, and the zero scale that is located the back is in same horizontal position with the highest of reference scale 8.

The graduated scale consists of a fixed rod 1 and a movable rod 3, a chute 2 is arranged in the fixed rod 1, a sliding block 5 matched with the chute 2 is arranged at the bottom of the movable rod 3, and the leveling bubble 4 is positioned at the top of the movable rod 3; the bottom of the graduated scale is connected with the reference scale 8 through a torsional spring 7, a limiting block 6 is arranged at the bottom of the graduated scale, and the bottom surface of the limiting block 6 is perpendicular to the graduated scale; an inclined plane is arranged on the top surface of the front end of the reference ruler 8, a roller 9 is arranged at the bottommost part of the inclined plane, and when the reference ruler 8 is in a horizontal state, the highest point of the roller 9 is lower than the top surface of the reference ruler 8; the top surface and the bottom surface of the reference ruler 8 are both cambered surfaces.

The working principle is as follows: when measuring, at first insert the pipe with reference ruler 8 in, let the bottom of reference ruler 8 and the bottom contact of pipeline, ensure through level bubble 4 that reference ruler 8 is in the horizontality after that, read numerical value through the front of scale this moment, improve the position of reference ruler 8 after that for the top surface of reference ruler 8 and the top contact of pipeline, then read numerical value through the back of scale, the difference of two last numerical values is the diameter of pipeline promptly.

In the measurement process, because the reference scale 8 is connected through torsional spring 7 with the scale, so when the diameter of well is less than the length of reference scale 8, can rotate reference scale 8 this moment, make 8 oblique insertions of reference scale get into the well, the gyro wheel 9 of 8 front ends of reference scale and the lateral wall contact of well this moment, thereby reduce the resistance that reference scale 8 received at the slip process, when the reference scale descends the pipeline, the reference scale received torsional spring 7's effect automatic re-setting and scale and keeps perpendicular this moment, thereby measure.

In the whole measuring process, because the inner wall of pipeline is the arc structure, so all design into the cambered surface with the top surface and the bottom surface of reference scale 8, so ensure that reference scale 8 can have good contact with the inner wall of pipeline in the measuring process, ensure measuring accuracy.

The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
