the utility model relates to a little space limiting bit depth dipperstick.

Background art:

measurement is the use of data to describe the observed phenomenon, i.e. to make a quantitative description of things, according to a certain law. The measurement is a quantitative process for non-quantitative real objects. In mechanical engineering, measurement refers to the process of understanding experimentally that a measured quantity is numerically compared with a standard quantity having a unit of measure to determine the ratio of the two. When the depth measurement is performed on a small space limited position, the electronic distance measuring instrument cannot accurately measure the value and the vertical distance which is inconvenient to measure by a measuring ruler is measured, so that the existing depth measuring tool has the use limitation.

The invention content is as follows:

the utility model discloses the technical problem that will solve is: can carry out the dipperstick of precision measurement to the electronic distance measuring device can not accurate measurement value and the inconvenient measurement of dipperstick plumbing apart from.

In order to solve the technical problems, the invention is realized by the following technical scheme: a small space limiting position depth measuring scale comprises a telescopic rule, a measuring rope, a conical hammer, a front end guide wheel, a retracting wheel, an upper pinch roller, a lower pinch roller, a support rod, a force measuring wheel, a spring and an end cover, the front end guide wheel is rotatably arranged at the front end of the telescopic ruler, the retracting wheel is rotatably arranged at the rear end of the telescopic ruler, the rear end of the measuring rope is wound on the retracting wheel, the front end of the measuring rope is fixedly connected with the conical hammer, the telescopic ruler is provided with an observation window, the support rod is slidably arranged in a guide hole on the telescopic ruler, the inner end of the guide hole is in threaded connection with an end cover, the force measuring wheel is rotatably arranged at the upper end of the support rod, the lower end of the support rod is slidably arranged on the end cover, the support rod is further fixedly provided with a stop ring, the spring is sleeved and installed on the support rod, two ends of the spring are respectively acted on the stop ring and the end cover, and the measuring rope is supported on the force measuring wheel and the guide wheel.

Preferably, the blocking ring is fixedly mounted on the support rod in a threaded manner.

Preferably, a pressing pin is screwed between each level of the scale of the telescopic ruler.

Preferably, the retractable wheel is provided with a handle.

Compared with the prior art, the utility model discloses an useful part is: when the measuring device is used, an operator puts the conical hammer into a small space, then slowly rotates the take-up and pay-off wheel to put down the measuring rope, then the measuring rope presses down the force measuring wheel, the scales on the supporting rod are recorded through the observation window, the pressure of the measuring rope on the force measuring wheel changes at the moment when the conical hammer touches the bottom, the supporting rod moves upwards at the moment, after the scale change of the supporting rod is observed through the observation window by the operator, the rotation of the take-up and pay-off wheel is stopped, the scales of the measuring rope at the horizontal ground are recorded at the moment, and the problem of accurate measurement of the vertical distance in a certain small space or under the condition of limiting positions is solved.

Description of the drawings:

the present invention will be further explained with reference to the accompanying drawings.

Fig. 1 is a schematic view of the overall structure of the present invention.

Fig. 2 is a sectional view of the internal structure of the present invention.

The specific implementation mode is as follows:

the present invention will be described in detail with reference to the following embodiments:

as shown in fig. 1 and fig. 2, the small space limiting position depth measuring scale comprises a telescopic rule 1, a measuring rope 2, a conical hammer 3, a front end guide wheel 4, a retractable wheel 12, an upper pinch wheel 13, a lower pinch wheel 14, a support rod 15, a force measuring wheel 16, a spring 17 and an end cover 18, wherein the front end guide wheel 4 is rotatably arranged at the front end of the telescopic rule 1, the retractable wheel 12 is rotatably arranged at the rear end of the telescopic rule 1, the rear end of the measuring rope 2 is wound on the retractable wheel 12, the front end of the measuring rope 2 is fixedly connected with the conical hammer 3, the telescopic rule 1 is provided with an observation window 11, the support rod 15 is slidably arranged in a guide hole on the telescopic rule 1, the inner end of the guide hole is screwed with the end cover 18, the force measuring wheel 16 is rotatably arranged at the upper end of the support rod 15, the lower end of the support rod 15 is slidably arranged on the end cover 18, the support rod 15 is further fixedly provided with a stop ring, the spring 17 is sleeved on the supporting rod 15, two ends of the spring 17 act on the blocking ring and the end cover 18 respectively, the measuring rope 2 is supported on the force measuring wheel 16 and the guide wheel 4, the position of the observation window 11 corresponds to the position of the guide hole, the supporting rod 15 and the measuring rope 2 are provided with scales respectively, and the scales on the supporting rod 15 are located on the upper portion of the blocking ring to avoid being blocked by the spring 17.
