Embodiment Construction
[0028] The present invention will be further described below in conjunction with the accompanying drawings.
[0029] see figure 1 , the present invention provides a shaft threaded water seal structure based on a sealed cavity, the main structural parts involved in its action include the shaft 1, the double-headed rectangular right-handed thread structure 2 and the four-headed rectangular left-handed thread structure processed integrally with the shaft 1 The screw structure 3 and the cavity 4 through which the rotating shaft 1 passes. Wherein, it can be seen from the simplified sectional view of the cavity 4 that the rotating shaft 1 only passes through the left end of the cavity 4, and its connecting part is also the area where the threaded water seal structure works. figure 1 It is only a simplified connection schematic diagram of the threaded water seal structure of the rotating shaft. For the actual structural design and thread distribution of the rotating shaft, please re...
