The scope of the utility model protection should not be limited.It should be noted that accompanying drawing using simplified form and using it is non-accurately
Ratio, only to convenient, clearly aid illustration the utility model embodiment purpose.
As shown in figure 1, the lithium battery hardness determination fixture of the present embodiment includes：The first measurement measurement of arm 1, second arm 2, hinge
Fitting 3, the first arc support 4, the second arc support 5, contact site 6, graduated scale 7 and pointer 8.
First measurement arm 1 is connected with the second measurement arm 2 by articulated elements 3, the first measurement measurement arm 2 of arm 1 and second
Rotated around articulated elements 3 in the plane perpendicular to articulated elements axis, articulated elements 3 is arranged at the first measurement arm 1 and the second measurement arm 2
End, the articulated elements 3 of the present embodiment is rotating shaft.First measurement arm 1 is identical with the second measurement structure of arm 2, and relative to test
The center line L of fixture is symmetrical arranged, the axis perpendicular of center line L and articulated elements, and is intersected with the axis of articulated elements.
Elastomeric element 9 is provided between the first measurement measurement arm 2 of arm 1 and second, elastomeric element 9 measures arm 1 by first
It is connected with the second measurement arm 2, the elastomeric element 9 of the present embodiment is spring, and is set close to articulated elements 3.Can be according to different hardness
It is required that, change the spring of different coefficient of elasticity.Elastomeric element is set between two measuring arm, when the first measurement arm and the second measurement arm
When being softened, elastomeric element is opened, and makes first, second measurement arm stress, when measuring battery core, can make measurement arm to battery core
Certain pressure is produced, it is more accurate to measure.
The first arc support 4 is provided with the first measurement arm 1, the second arc branch is provided with the second measurement arm 2
Support part 5, the finger of operating personnel may pass through the arc support on two measurement arms, facilitate hand-held.In the first measurement arm 1 and the
Two measurement arms 2 end relative with articulated elements is respectively arranged with contact site 6, and the contact site 6 of the present embodiment is ball-type structure, with
The roll structure of ballpoint tip is similar, and contact site 6 is in contact with battery surface, and the area that contact site is contacted with battery surface is
0.1mm2~10mm2.Contact site uses ball-type structure, and contact site can be made to be slided on battery core surface, realizes continuous measurement, and
And battery core will not be damaged.
Graduated scale 7 and pointer 8, graduated scale 7 and the phase of pointer 8 are respectively arranged with the first measurement measurement arm 2 of arm 1 and second
