When opening and closing the door, due to the increase in the fit clearance caused by the wear of the plastic parts, the door body shakes, makes a rotating abnormal sound, the hand feeling becomes heavy, and in severe cases, problems such as jamming occur.

A square slot 309 adapted to the square plug 308 is formed at the bottom end of the insertion shaft 202.

[0046] Specifically, during the rotation of the insertion shaft 202, the square plug 308 can be driven to rotate, so that the threaded column 307 can be driven to rotate during the rotation of the shower room glass door.

[0047] Please refer specifically to Figure 8 , a sliding disk 3010 and a sealing piston disk 3011 are respectively slidably arranged on the inner wall of the fixed cylinder 306, and lubricating oil 3012 is poured below the sealing piston disk 3011 inside the fixed cylinder 306.

A threaded hole threadedly connected to the outer surface of the threaded column 307 is formed on the upper surface of the sliding disk 3010.

[0048] Specifically, during the rotation of the threaded column 307, the sliding disk 3010 and the sealing piston disk 3011 can be automatically driven to move downward, so as to achieve the purpose of automatically spraying the lubricating oil 3012 from the end of the oil spray pipe 302.

At the same time, the setting of the oil outlet one-way valve and the oil suction one-way valve enables the oil outlet pipe 3014 to only discharge oil unidirectionally, and the oil suction pipe 3015 to only suck oil unidirectionally.

[0053] In summary, in this embodiment, by providing the lubrication assembly 300, when the shower room glass door is opened, it can drive the insertion shaft 202 to rotate. The rotation of the insertion shaft 202 drives the square insertion block 308 to rotate. The rotation of the square insertion block 308 drives the threaded column 307 to rotate. The rotation of the threaded column 307 drives the sliding disk 3010 to move downward. When the sliding disk 3010 moves downward, it drives the sealing piston disk 3011 to move downward through the connecting rod 3013, so as to squeeze the lubricating oil 3012 at the bottom of the fixed cylinder 306 into the annular oil pipe 301 through the oil outlet pipe 3014 and the connecting pipe 3017, and spray it out to the bottom of the angular contact thrust ball bearing 204 through the spray oil pipe 302, so that the lubricating oil 3012 enters the middle of the bottom ring 2041 and the rotating ring 2042 to lubricate the metal balls 2043. When the shower room glass door is closed, the insertion shaft 202 drives the threaded column 307 to reverse. The reverse rotation of the threaded column 307 drives the sliding disk 3010 and the sealing piston disk 3011 to move upward. When the sealing piston disk 3011 moves upward, the dripping lubricating oil 3012 is sucked back into the inner bottom of the fixed cylinder 306 through the oil suction pipe 3015, realizing the recycling of the lubricating oil 3012, and effectively reducing the loss of the metal balls 2043 in the angular contact thrust ball bearing 204.

[0054] Working principle: During the actual installation of the rotating shaft of this shower room, first insert the angular contact thrust ball bearing 204 from the bottom of the fixed seat 201 into the installation hole 209, and insert the support seat 203 into the installation hole 209. Then, turn the two hexagon socket head cap screws 207 so that the hexagon socket head cap screws 207 enter the threaded deep groove 2010 and are inserted into the annular limit groove 208 on the support seat 203 in the installation hole 209 to effectively fix the support seat 203. After that, install the rotating shaft body 100 on the shower room glass door. Finally, install the rotating shaft body 100 through the insertion shaft 202 into the hole of the angular contact thrust ball bearing 204 inside the fixed seat 201, so that the insertion shaft 202 of the rotating shaft body 100 contacts the angular contact thrust ball bearing 204 to produce a rotational mating relationship, enabling the glass door of the shower room to be light and have no frictional loss when opening the door, and ensuring the long-term stability of the rotating shaft switch function, so as to achieve the purpose of improving production efficiency and reducing production costs. At the same time, before installing the shower room glass door, first thread the internal thread sleeve 303 onto the bottom of the fixed seat 201, make the rotating disk 304 abut against the bottom of the fixed seat 201, and insert the square insert block 308 into the square slot 309 on the insertion shaft 202. Thus, when opening the shower room glass door, it can drive the insertion shaft 202 to rotate. The rotation of the insertion shaft 202 drives the square insert block 308 to rotate, the rotation of the square insert block 308 drives the threaded column 307 to rotate, and the rotation of the threaded column 307 drives the sliding disk 3010 to move downward. When the sliding disk 3010 moves downward, it drives the sealing piston disk 3011 to move downward through the connecting rod 3013, thereby squeezing the lubricating oil 3012 at the bottom of the fixed cylinder 306 into the annular oil pipe 301 through the oil outlet pipe 3014 and the connecting pipe 3017 and spraying it out through the oil spraying pipe 302 to the bottom of the angular contact thrust ball bearing 204, so that the lubricating oil 3012 enters the middle of the bottom ring 2041 and the rotating ring 2042 to lubricate the metal balls 2043. When the shower room glass door is closed, the insertion shaft 202 drives the threaded column 307 to reverse. The reverse rotation of the threaded column 307 drives the sliding disk 3010 and the sealing piston disk 3011 to move upward. When the sealing piston disk 3011 moves upward, it sucks the dripping lubricating oil 3012 back into the bottom of the fixed cylinder 306 through the oil suction pipe 3015, realizing the recycling of the lubricating oil 3012, and thus effectively reducing the loss of the metal balls 2043 in the angular contact thrust ball bearing 204.
