[0007] The two rotating shafts on the right side are located inside the two fixed blocks on the right side, and the multiple cylindrical grooves are respectively connected to the multiple movable grooves. The cylindrical grooves and the movable grooves pass through the fixed blocks. The side surface of the other end of the locking rod is inclined, and the other end of the locking rod extends to the inside of the locking hole.

When the device is installed at a designated location, it is only necessary to ensure that the vehicle rollover direction is consistent with the layout direction of the site. There is no need to deliberately adjust the position of the device, which saves time for device installation and adjustment, thereby making the device quick to install. If the site rolls over to the right, push the flip plate to the right so that the two shafts on the right enter the two fixed blocks on the right. In the process of pushing, the two locking rods on the right are squeezed by the two fixed blocks on the right and shrink into the cylindrical groove. At this time, the two springs on the right are in a compressed state. When the two shafts on the right are completely entered into the two fixed blocks on the right, the two springs on the right rebound, so that the right The two locking rods return to their positions and enter the locking holes opened inside the two fixed blocks on the right side respectively. At this time, the right side of the flip plate is limited. The vehicle is driven onto the top of the flip plate, and the two hydraulic cylinders run upward, causing the two lifting blocks and the rotating plate connected in the middle to move up synchronously, so that the flip plate is flipped clockwise with the two right rotating shafts as the center. While the rotating plate rotates itself, it moves along the through groove to flip the flip plate to the right until the vehicle rolls over. Similarly, pull the two shift blocks on the right side to disengage the two locking rods from the corresponding locking holes respectively, and push the flip plate to the left to flip the flip plate counterclockwise to the left. The flip angle of the flip plate can be adjusted in real time according to different vehicle models, thereby improving applicability.

[0018] 2. The utility model provides a vehicle rollover angle test device, in which two limit plates and a limit column are connected to the outer wall of the flip plate. During the translation of the flip plate, the limit column moves along the limit groove, so that the flip plate can maintain a straight line translation. At the same time, the multiple rollers installed on the top of the base make the translation process of the flip plate faster. Baffles are connected on both sides of the flip plate to facilitate the translation of the flip plate. BRIEF DESCRIPTION OF THE DRAWINGS
