On the other hand, the downward movement of the oblique protective plate 8 will force the two The top ends of the two hinged rods 15 slide away from each other, and at the same time, the bottom ends of the two hinged rods 15 are forced to slide away from each other, thereby reducing the distance between the two hinged rods 15 on the same side, that is, compressing the elastic recovery component therein, further weakening the collision and impact force, avoiding further transmission of the collision and impact force, and providing an upward elastic force for the downward movement of the oblique protective plate 8, further avoiding the rigid deformation of the oblique protective plate 8, and the hinged rod 15 and the elastic recovery component are arranged on both sides of the transverse mounting plate 3, which can provide side protection for the station ventilation and air-conditioning outdoor unit therein on both sides of the transverse mounting plate 3, and finally realizing anti-deformation protection for the top and both sides of the station ventilation and air-conditioning outdoor unit.
