Detailed Description

Example 1:

referring to the attached drawings 1-5, the stable-transmission air inflation cabinet outlet mechanism comprises a load switch mechanism, a main shaft 2, a clamping plate 1 and a supporting plate 3.

Backup pad 3 and splint 1 cooperation are fixed to form one and hold the cavity, and load switch mechanism is located and holds the cavity, and main shaft 2 passes splint 1 and stretches into to holding in the cavity and load switch mechanism cooperation. The supporting plate 3 is specifically arranged in a U shape, and the clamping plate 1 is positioned above the U-shaped opening and is used for being connected and fixed with the supporting plate 3 to form a sealing effect. Further, the fixing mode of the two can be bolt fixing.

The spindle 2 is provided with a plurality of reinforcing ribs 21 in the axial direction at one end above the clamping plate 1, the number of the reinforcing ribs 21 is six, and the six reinforcing ribs 21 are distributed in a circumferential array and correspond to an external driving rod, so that the driving rod is matched with the spindle 2 to drive the spindle 2 to rotate. Be equipped with the spigot surface on the strengthening rib 21 top, the actuating lever of being convenient for stretches into, still be equipped with breach 22 on the strengthening rib 21, adopt the setting of breach 22, improve holistic radiating effect, prevent in the use, the friction themogenesis.

A fifth bearing 4 is arranged between the main shaft 2 and the clamping plate 1, the fifth bearing 4 is specifically a ball bearing, the specific structure of the fifth bearing is that the fifth bearing comprises an inner ring 41 and an outer ring 42, a plurality of balls 43 are arranged between the inner ring 41 and the outer ring 42 to form a ball 43 type bearing, and the structures of the fifth bearing 4, the third bearing and the fourth bearing are all the same, so that the rest of the structures are not repeated.
