The mobile support platform 1 that turns to includes support frame 4 and the universal wheel 5 with braking function.
The universal wheel 5 is four, and four universal wheels are welded on four angles of the bottom of support frame 4.
The air-conditioning support 2 includes two air-conditionings main support 6 and two rubber strips 7, and rubber strip 7 is laid in the main support of air-conditioning
On 6.
The blower fan supporting mechanism 3 includes that two blower fans support 8 and connecting plate 9.
The main support 6 of the support frame 4, air-conditioning and blower fan support 8 are processed by the square steel tube of 50mm × 50mm.
The section of the rubber strip 7 is the square of 50mm × 50mm, and length direction has depression circular hole in identical distance, circle
There is fixing hole inside hole.
The support frame four, 4 top angle and middle upper portion are stretched out and higher than the place plane of rubber strip 7.
Lateral separation between two rubber strips 7 can adjust.
Described two blower fans support 8 and between distance up and down it is adjustable.
Compared with prior art, universal fixture of the invention reduces frock input quantity, improves air conditioning for automobiles noise
Test all-purpose frock overall utilization rate, can meet the automobile air conditioning system and condensation fan of Multiple Type on the market, evaporation fan
Test fixture demand, while the staff for avoiding test carries out the situation of test jobs below air-conditioning, it is to avoid safety is hidden
Suffer from, reduce air conditioning for automobiles noise testing universal fixture whole cost input, facilitate the test of various car model air-conditionings and blower fan
Demand, and it is easy to air-conditioning installation and movement.The present invention has easy to use, highly versatile, Stability Analysis of Structures, is easy to make processing
The advantages of.
