Power, avoids pullling in impact test process center line detection device (especially electricity refers to cable) and comes off.
Cover board and tension disc can effectively prevent pullling when cable is replaced.Also, when cable damages, user can be with
It is rapid at any time to replace, so as to not influence the use of test equipment.
The main body is provided with symmetrical through hole.Open up through hole to be used to reduce quality itself, reduce effect of inertia.
The elastic component is spring.The locating piece is steel ball.
The belt force sensor is used for the measurement of belt force in crash tests, using with intensity Gao Ermi
Degree and small, the titanium alloy material of good mechanical property so that metal material has preferable strain effects in measurement process.
The belt force sensor is used for the measurement of belt force in crash tests, and all surfaces are all through overground
Light processing, to prevent damage dummy or bag material, while traction and frictional error is eliminated, protection is expensive on smooth surface
Crash tests dummy it is without damage.
Due to being using above technical scheme, technique effect of the invention：Overall structure of the present invention is simple, small,
And internal part stress is rotatable, can more fully be tested.Present invention operation is easy and is not easy by space and extraneous ring
The influence in border, locking it is firm, can compressive resistance it is big, have enough impact strengths, it is highly practical, especially meet vehicle impact testing will
Ask.

Embodiment
The present invention is described in more detail with reference to the accompanying drawings and detailed description.
Structure of the present invention is as follows：
A kind of rotatable belt force sensor of force rod, 1 top of main body are additionally provided with groove 6, the groove 6
For installing foil gauge, 1 side of main body is internally provided with annular buckling groove 12, and being equiped with stress in the main body 1 can revolve
Rotation member, the stress rotatable part are clamped with annular buckling groove 12；
The stress rotatable part includes force rod 2, built-in rod 9, elastic component and locating piece, and the built-in rod 9 is installed
In the inside of 2 end of force rod.2 end of force rod is equipped with location hole 13, and the built-in rod 9 is equipped with U-shaped elongated slot 8, described
Elastic component is equipped between 9 end of built-in rod and force rod 2.Spring 10 is connected by being clamped with built-in rod, or in built-in rod
Afterbody is equipped with the open ended spacing cavity of spring 10, is inserted for spring 10.
The locating piece 13 is arranged in U-shaped elongated slot 8 and is adapted with location hole 13, is adapted and refers to, locating piece diameter omits
More than location hole 13, finally withstand on location hole 13, expose 13 part of location hole and be stuck in annular buckling groove 12.The locating piece
It is arranged in annular buckling groove 12.
The elastic component is spring 10.The locating piece is steel ball 11.
1 side of main body is equipped with the cover board for being used for being connected with detection device, and the cover board includes inside cover plate 3 and outside
Cover board 4.
1 side panel of main body is equipped with the tension disc 5 for fixed test equipment.
Institute's main body 1 is provided with symmetrical through hole 7.
The belt force sensor force rod of the present invention is installed by following step：
1st, steel ball 11 is put into inclined U-shaped 8 bottom of elongated slot of bar inner part, and 11 deviation position of steel ball is prevented with instrument.
2nd, spring 10 is put into force rod 2.
3rd, the mounted built-in rod 9 of step 1 is put into force rod 2 vertically, applies external force and rotate, make steel ball 11 lucky
Be aligned force rod 2 on location hole 13, at this time spring 10 be in compressive state, give bar built-in rod 9 one outside power.Steel ball 11
Under built-in rod 9 and the collective effect of location hole 13, it is stuck at location hole 13, at this time, installation is complete for force rod 2.
4th, two parallel force rods 2 are first removed, after safety belt is placed, then force rod 2 is inserted into main body 1, steel ball 11
After being stuck in the annular buckling groove 12 of main body 1, belt force test is then carried out.
5th, off-test, when removing sensor, is gently pressed built-in rod 9 with hand inward, compresses spring 10, at this time steel ball
11 lose the constraint of location hole 13, easily can remove force rod 2.
