Abstract

The invention belongs to the field of sports equipment and relates to a parallel constant force device for measuring human body girth. The device is formed by a mutual connection of a base, a standing column, a sliding sleeve, a square sliding sleeve, a square sliding rod, a short square tube, a U-shaped groove, a tape measure, a clip, a pulley, a lifting rope, a pouring weight and other components. The device has the advantages that a standing column height value corresponding to an upper edge of the sliding sleeve of the device is capable of enabling a repeatable measurement position to be the same and be controllable. When the tape measure is around a certain part of the human body for measuring the girth, the upper edges of the tape measure are overlapped together and are in a parallel state. A girth value which is read is relatively accurate; errors which exist in a previous deflection measurement of the tape measure are avoided. The pouring weight pulling lifting rope clip can enable the tape measure to obtain the same constant tensile force after every time measurement. The girth value which is read is relatively accurate; defects of the errors existing in the dimension caused by the magnitude of the hand-pulling tape measure force are prevented.

Description

Parallel constant force is measured the device of human body degree of enclosing

Technical field

The invention belongs to field of sports equipment, relate to a kind of device of parallel constant force measurement human body degree of enclosing.

Background technology

Existing while having following problem: a, tape measure around human body a part measurement degree of enclosing with tape measuring human body degree of enclosing, the upper edge of tape measure, lower edge are leaned on mutually in degree of enclosing that deflected condition reads value, with on tape measure along being superimposed compared with degree of enclosing that parastate the reads value, the former can read and be greater than actual scale error because of the non-transversal degree of enclosing of tape measure deflection formation; B, pull degree of enclosing that size the reads value of tape measure two ends pulling force, also can have the error different from actual size; C, human body are difficult for ensureing to measure in same position with last time with tape measuring human body a part degree of enclosing in erectility again, and degree of the enclosing value that reads also can exist error.

Summary of the invention

The object of the invention is the problem existing in above-mentioned background technology for solving, provide a kind of parallel constant force to measure the device of human body degree of enclosing, it is made up of following technical scheme: base is placed in ground, column lower end is welded to connect at described base middle part, on described column, be carved with scale value, sliding sleeve is enclosed within outside described column and is located by the first trip bolt, on described sliding sleeve, be its position, measuring point along corresponding scale on column, side's sliding sleeve left end is welded to connect in sliding sleeve side, described side's slide bar left end inserts described side's sliding sleeve right-hand member square hole and is located by the second trip bolt, be welded to connect short square tube at described side's slide bar middle part, be welded to connect U-lag at short square tube front end, described U-lag left end edge is riveted by rivet after aliging with 0 of tape measure the inner, , body measurements is walked around through described U-lag in tape measure outer end, described tape measure outer end is through clamp aperture, pressing down pressure handle downforce vertically can be fixed on described clip outside tape measure, on described side's slide bar right side by the hinged pulley of axle, lifting rope left end is fixedly connected with clip circular hole, pulley is walked around at described lifting rope middle part, described lifting rope right-hand member is fixedly connected with pouring weight upper end hole, lifting rope clip described in described pouring weight tractive, can make described tape measure keeping parallelism state carry out constant tension measurement human body degree of enclosing.

While using this device, measured uprightly stands, and adjusts to slide over scle height on column and determine that measured position located by the first trip bolt; The side's of adjustment slide bar length is convenient to measure symmetrical limbs position, is located by the second trip bolt; U-lag left end and inner 0 of tape measure are touched to tested position, tested position is walked around again through U-lag in tape measure outer end, lifting rope can make clip and tape measure obtain constant pulling force under the tractive of pouring weight, and inner 0 the institute's respective value of U-lag left end and tape measure is the degree of enclosing at tested position.

Use this device with existing with the beneficial effect that tape measuring human body degree of enclosing is compared to be: on a, this device sliding sleeve, can make repeated measure position identical controlled along corresponding column height value; B, this device tape measure are during around human body a part measurement degree of enclosing, and the upper edge of tape measure is superimposed in parastate, and degree of the enclosing value reading is relatively accurate, have avoided the error that tape measure deflection measurement exists in the past; C, this device pouring weight tractive lifting rope clip can make tape measure measure at every turn and obtain identical constant pulling force, and the degree of enclosing reading value is relatively accurate, and the size of having avoided in the past pulling tape measure two ends Yin Lali can make survey degree of enclosing value have the drawback of error.
