There is nut on body, in one-to-one correspondence shape connection between nut and two sliding blocks.In use, car model is first placed into four supports
Between disk, so that wheel is located between two clamping plates of pallet；Then, by spanner, sequentially pass through pull mouth pull screw rod rotation, from
And two clamping plates is driven to run to direction adjacent to each other, the positioning to car model can be completed in clamping wheel.This support
Mechanism is when the four-wheel to car model positions, without drilling to wheel, to reduce the manufacture of car model
Cost.Moreover, car model is not necessarily to device to hole during the installation process, it is easy for installation.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the automobile wind tunnel test balance supporting mechanism of the utility model；
Fig. 2 is the A-A cross-sectional view of Fig. 1.
Specific embodiment
The utility model is described in further details below in conjunction with attached drawing.
As depicted in figs. 1 and 2, the automobile wind tunnel test balance supporting mechanism of the utility model includes day rotating disc 1, day
There are four relief hole, the position of four relief holes is corresponding with the position of four wheels of automobile for setting in the disk of rotating disc 1.It is described
There is horizontally disposed pallet 4 in relief hole, the bottom of pallet 4 is provided with supporting element 7.On the upper disk surface of the pallet 4
