Description
Technical field
This utility model belongs to tape measure technical field, is specifically related to a kind of human body girth diameter and measures tape measure.
Background technology
Carrying out the measurements such as upper-arm circumference, head circumference, chest measurement, abdominal circumference is clinically that clinician's physical examination commonly uses project, and only measures with a rectangular tape these projects clinically at present.When measuring, tape is wrapped in position that human body is surveyed circle, and then gauger's both hands drag the two ends last reading of tight tape respectively, and its degree of tightness be wound around only is grasped by the subjective desire of gauger.Because human body has certain flexibility, when causing the different gauger in the same measuring point of same individuality to measure, the measured value difference of gained is comparatively large, and the same time order and function of even same gauger measures the measured value difference of gained also clearly to same measurand twice.Especially abdominal part, difference can reach several centimetres sometimes, and this just causes being unfavorable for the assessment of individual growth development condition clinically and the monitoring of disease condition change.
Utility model content
There is the large problem of measurement error mainly for the tape measure of existing measurement human body girth diameter in this utility model, provides a kind of human body girth diameter to measure tape measure.
This utility model is the technical scheme taked that solves the problem:
A kind of human body girth diameter measures tape measure, comprises reel, tape measure, wherein: also comprise flexible rule box, clutch shaft bearing, gear wheel, saucerspring, the second bearing, pinion, conveyer belt and clip, the two ends of clutch shaft bearing are arranged on the top of flexible rule box, gear wheel is contained on clutch shaft bearing, saucerspring is also contained on clutch shaft bearing, one end of saucerspring is fixed on the longitudinal axis of gear wheel, the other end of saucerspring is fixed on flexible rule box, the two ends of the second bearing are arranged on the bottom of flexible rule box, pinion is contained on the second bearing, reel is also contained on the second bearing, one end of conveyer belt to be enclosed within clutch shaft bearing and to engage with gear wheel, the other end of conveyer belt to be enclosed within the second bearing and to engage with pinion, tape measure twists on reel and one end of tape measure is fixed on reel, the other end of tape measure is connected with clip and extends to the outside of flexible rule box.
Further, clip described in the utility model is made up of train wheel bridge, lower plate, tooth engaged and spring, one end of train wheel bridge and lower plate is all provided with connecting plate, two connecting plates are provided with axle, spring is contained on axle, and one end of spring withstands on train wheel bridge, and the other end of spring withstands on lower plate, tooth engaged is arranged on the other end of train wheel bridge, and lower plate is connected with the external part of tape measure.
This utility model adopts technique scheme, when tape measure is drawn out time, tape measure drives the second bearing rotary, second bearing drives pinion to rotate, pinion drives clutch shaft bearing to rotate by conveyer belt, clutch shaft bearing drives gear wheel to rotate, gear wheel drives saucerspring to tighten, like this when decontroling tape measure, under the effect of saucerspring elastic force, saucerspring drives gear wheel to rotate, and gear wheel drives clutch shaft bearing to rotate, clutch shaft bearing drives the second bearing rotary by conveyer belt, and then is rolled by tape measure.During measurement, tape measure is pulled out, after being wound in human body detected part one circle, open clip, be sandwiched in clip by tape measure blade, and ensure that clip is closed and still can be free to slide in the space of clip with tape measure blade, now the hands of gauger is decontroled human body girth diameter and is measured tape measure, allow it rely on the contractility of resilience spring that tape measure is tightened up and be affixed on human body detected part, after its tightening process terminates, in clip place reading, measured value can be obtained.
