Description

Flexible ruler for measuring heisht

The utility model relates to a kind of height survey instrument, particularly a kind of Flexible ruler for measuring heisht that is used for measuring human body.

At present people's gage of being used for measuring the human body height mainly contains two kinds, a kind of commentaries on classics chi, and a kind of is can weigh and the height measurer of weighing of energy height.These the two kinds high instruments of amount, the former measuring accuracy is not high, uses inconvenient yet; Latter's volume is big, price is high, be not easy to carry the use of inapplicable family.

The purpose of this utility model just provide kind of a measuring accuracy height, simple to operate, volume is little, portable Flexible ruler for measuring heisht.

The utility model is achieved in that it is mainly by group usefulness such as rod support, chi box, steel commentaries on classics chi, stator, spring case, rotatable springs.Spring case is contained on the interior fixed cylinder of chi box, the rotating piece type automatic spring is contained in the spring case, an end of spring is fixed on the bayonet socket of cylinder, its other end passes spring case and links together with the commentaries on classics chi end that changes outside spring case, changeing the chi commentaries on classics places at the outer of spring case, the little outlet that the other end of commentaries on classics chi passes the chi box is fixed on the outer stator of chi box, the positive front of chi box has a form, and the chi box is screwed on rod support.During use, the bottom surface of rod support is placed on the ground as reference field, holds stator then, will change chi and pull out, change chi simultaneously and drive the spring case rotation, cause the spring in the spring case to change tight, make datum line aligning commentaries on classics chi zero line on the form at last, again that stator is fixing motionless on the wall, mobile Flexible ruler for measuring heisht, the rod support base plate is parallel with people's head, and this moment, Flexible ruler for measuring heisht form datum line indication changeed the chi scale, was exactly tested person's height.Stator is decontroled in the high back of amount, under the elastic force effect of spring, is recovered in the chi box changeing chi.

The utility model has been concentrated the advantage of tape measure and the height measurer of weighing: the measuring accuracy height, volume is little, in light weight, cost is low, easy to use, be easy to carry, particularly suitable family, school, kindergarten use, and its appearance provides a kind of desirable Flexible ruler for measuring heisht for people.
