Abstract
The utility model discloses an internal locking type air valve device which comprises an annular valve shell. The valve shell comprises an annular shell wall, the shell wall is provided with a driving shaft hole and a supporting shaft hole, the supporting shaft hole is provided with a supporting shaft rod, the driving shaft hole is provided with a driving shaft rod, an air plate part is connected between the supporting shaft rod and the driving shaft rod in a sleeved mode, and the air plate part comprises a hollow cylindrical air plate sleeve and a disc-shaped air plate body. According to the internal locking type air valve device, by means of a first sleeve body and a second sleeve body in the air plate sleeve, when the supporting shaft rod or the driving shaft rod is damaged, a user only needs to replace the damaged supporting shaft rod or the damaged driving shaft rod, and the air plate body does not need to the replaced. Due to the fact that embedded matching of locking ribs and locking grooves is adopted, the internal locking type air valve device is easy to mount, firm in fixation and not prone to disengagement. The internal locking type air valve device is compact in structure, easy to demount and mount and high in practicability.
