Description
Technical field
The utility model relates to measuring technique, in particular to a kind of device for measuring human arm quality.
Background technique
In daily life, people more and more pay close attention to own bodies situation, such as height, weight, body fat ratio, heart rate
Deng.For certain specific reasons (such as body-building or body-builders are games results consideration), it can be concerned about arm shape, concern
Arm muscles and fat ratio pay close attention to the annual variation of arm.Or out of sheer curiosity, people can want to measure oneself or he
The arm quality of people.And arm is human body inalienable part, can not simply be weighed with scale.And human body and
It is complicated, the branch and uneven in human body such as bone, fat, muscle, body fluid, if simply body averag density is equal
It is calculated in arm density, then error is larger.
Utility model content
The technical problems to be solved in the utility model is to overcome deficiency in the prior art, provides a kind of measurement arm matter
The device of amount.
In order to solve the technical problem, the solution of the utility model is:
A kind of device of measurement arm quality is provided, upper flume and lower flume including tubular, the bottom of upper flume is set out
The opening at the mouth of a river, lower flume sets water valve；When upper flume bottom and lower flume open butt joint, water outlet can realize nothing with water valve
Leakage docking；
The side wall of the lower flume is equipped with one for protruding into the tube channel of arm, and tube channel is provided with leakproof rubber
Pad；Be located at tube channel or more two sides on the side wall of lower flume and the laser pen of a horizontal direction be respectively set, with laser pen
Opposite is lauched two white panels of setting in groove sidewall；
The device further includes a vertical glass tube, and bottom is communicated with the bottom of lower flume.
In the utility model, the water outlet in upper flume bottom is equipped with rubber stopper, and the top of the water valve is equipped with connecting tube；
When upper flume bottom and lower flume open butt joint, connecting tube can be inserted into rubber stopper and realize that No leakage docks.
In the utility model, the glass tube is equipped with scale or scale for measuring water level.
In the utility model, have waterproof coating or wrappage outside the laser pen.
In the utility model, the upper flume and lower flume are had the same diameter.
Compared with prior art, the utility model has the beneficial effects that
1, the utility model features simple structure, easy to operate, measurement error is small.
2, the utility model measures arm volume using drainage, then obtains arm averag density by simple computation,
So that arm quality is calculated, fast and easy, securely and reliably.

Specific embodiment
With reference to the accompanying drawing, the implementation of the utility model is described in detail:
Fig. 1 is the general assembly schematic diagram of the utility model measurement arm quality device.The device includes the tubular of same diameter
Upper flume 1 and lower flume 3, the bottom of upper flume 1 sets the water outlet 2 with rubber stopper, and the opening of lower flume 3 sets water valve 5；Water
The top of valve 5 is equipped with connecting tube；When 1 bottom of upper flume and 3 open butt joint of lower flume, connecting tube can be inserted into rubber stopper simultaneously real
Existing No leakage docking.The device further includes a vertical glass tube 4, glass tube 4 be equipped with scale for measuring water level or
Scale, bottom are communicated with the bottom of lower flume 3.
The side wall of lower flume 3 is equipped with one for protruding into the tube channel 7 of arm, and tube channel 7 is provided with leakproof rubber pad；
Be located at about 7 two sides of tube channel on the side wall of lower flume 3 and the laser pen 6 of a horizontal direction be respectively set, with laser pen 6
Two white panels 8 are set on opposite 3 side wall of lower flume.Have waterproof coating or wrappage outside laser pen 6.
Utilize the method for the device measurement arm quality, comprising the following steps:
(1) two laser pens 6 are opened, the laser holding for emitting it is horizontal, is radiated in two white panels 8 respectively；
(2) arm is protruded into empty lower flume 3 from tube channel 7, keeps natural relaxation state, the leakproof rubber of tube channel 7
Rubber mat banding arm simultaneously realizes sealing；
(3) distilled water is injected into lower flume 3, is submerged arm all；Since arm density is greater than distillation water density
And it is in natural relaxation state, arm can be sink to 3 bottom of lower flume and block downside laser；The water level recorded in glass tube 4 is high
Degree is h1, and the distilled water volume being added is V1, quality M1；
Calculate the volume V of armA:
In formula,The respectively diameter of lower flume 3 and glass tube 4；π is pi；
(4) high concentration salt water is packed into upper flume 3, the quality for recording upper flume 3 at this time is m1；High concentration salt water is optional
The strong brine that salt is prepared, has no special requirements to its concentration.
Upper flume 3 is placed in the opening of lower flume, water outlet 2 is made to realize that No leakage docks with water valve 5；Open water valve 5
High concentration salt water is injected into lower flume 3, makes that the distilled water in lower flume 3 becomes salt water and density gradually increases, when in lower flume 3
Brine density and arm averag density when being consistent, the arm in natural relaxation state can level be suspended in lower flume 3
In, the hot spot of two laser pens 6 can be located in two white panels 8 simultaneously at this time, close water valve 5；Record upper flume 3 at this time
Quality is m2, the height after water level rises in glass tube 4 is h2；
(5) the averag density ρ of arm is calculated according to the following formulaA:
(6) further according to mass MA=ρA×VA, calculate arm mass MA:
