[0002] The notebook rotating shaft refers to the rotating component used to connect the screen and the keyboard in a notebook computer. It enables the screen and the keyboard to rotate relative to each other and allows users to use the notebook computer at different angles and postures. The rotating shaft is usually located at the bottom or the keyboard area of the notebook computer and is connected to the upper part of the screen. It allows the screen to tilt backward to the maximum angle, usually about 180 degrees, so that users can comfortably view the screen. In addition, the rotating shaft can also achieve the forward tilt of the screen, making it closer to the keyboard for easy carrying and storage.
[0003] When the existing notebook computer rotating shaft is in use, due to the large friction between the connecting block and the rotating shaft, the notebook computer rotating shaft will be damaged after long-term use. In addition, when the existing notebook computer rotating shaft is in use, due to the lack of adjustment of the pressure between the connecting block, the gasket and the clamping ring, there is always a large friction between the connecting block, the gasket and the clamping ring. When used for too long, the components of the connecting block, the gasket and the clamping ring will not be able to be used normally due to severe wear. Therefore, it is necessary to provide a long-life rotating shaft to solve the above technical problems. Summary of the Utility Model

[0024] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail in conjunction with the accompanying drawings.
[0025] Please refer to Figures 1-4 , a long-life rotating shaft. As a further proposed technical solution of the present utility model, it includes: a first mounting plate 1, the lower end of the first mounting plate 1 is connected to one end of the rotating shaft 2, the other end of the rotating shaft 2 is provided with a nut 3, the outer surface of the rotating shaft 2 is sleeved with multiple groups of clamping rings 4, the outer surface of the rotating shaft 2 is sleeved with multiple groups of gaskets 5, the outer surface of the rotating shaft 2 is sleeved with a connection block 6, and a limiting block 7 is provided on the rotating shaft 2;
[0026] A plug 8, the plug 8 is inserted into the upper end of the connection block 6, multiple groups of sleeve rods 9 are uniformly arranged inside the connection block 6, one end of each group of sleeve rods 9 is inserted with an insertion rod 10, a spring 11 is sleeved outside each group of insertion rods 10, the other end of each group of insertion rods 10 is connected to the outer surface of the connection ring 12, multiple groups of movable balls 13 are uniformly arranged inside the connection block 6, and the lower end of the connection block 6 is connected to the upper end of the second mounting plate 14.
[0027] Specifically, four groups of mounting holes are evenly formed on the first mounting plate 1. Through the arrangement of the four groups of mounting holes, the first mounting plate 1 can be fixed at the desired position.
[0028] Specifically, the outer surface of one end of the rotating shaft 2 is provided with threads corresponding to the nut 3. Due to the arrangement of the threads, when the nut 3 is rotated, the positions of the connecting block 6, the gasket 5 and the clamping ring 4 can be fixed.
[0029] Specifically, two groups of clamping rings 4, two groups of gaskets 5 and one connecting block 6 are movably arranged on the outer surface of the rotating shaft 2. The two groups of clamping rings 4, the two groups of gaskets 5 and the one connecting block 6 are movably sleeved on the outer surface of the rotating shaft 2 at intervals in sequence. By arranging the clamping rings 4 and the gaskets 5 on both sides of the connecting block 6, the position of the connecting block 6 can be fixed.
[0030] Specifically, the two groups of clamping rings 4 and the connecting ring 12 are both made of rubber. Since the clamping ring 4 is made of rubber, when the clamping ring 4 is subjected to external pressure, it will deform, and further the positions of the connecting block 6 and the gasket 5 can be fixed. Since the connecting ring 12 is made of rubber, when the multiple movable balls 13 move, the connecting ring 12 can be deformed, and further the multiple inserting rods 10 can start to move.
[0031] Specifically, two groups of through holes are symmetrically formed at the upper end of the connecting block 6, and plugs 8 are movably inserted into the two groups of through holes. When lubricating oil needs to be added, the two plugs 8 can be removed, and then the lubricating oil can be poured into the connecting block 6 through the two through holes. A groove is formed inside the connecting block 6, and multiple inserting holes are evenly formed on the inner wall of the groove. Through the arrangement of the multiple inserting holes, multiple sleeve rods 9 can be correspondingly arranged, ensuring the normal operation of the devices inside the connecting block 6.
[0032] Specifically, the multiple inserting rods 10 are all movably inserted into the sleeve rods 9. When the multiple inserting rods 10 start to move inside the multiple sleeve rods 9, when the multiple movable balls 13 move, the impact force can be reduced through the connecting ring 12, the multiple sleeve rods 9 and the multiple inserting rods 10, and further the service life of the connecting block 6 is improved.
[0033] Specifically, the multiple movable balls 13 are all movably arranged in the groove inside the connecting block 6. When the multiple movable balls 13 start to move in the inner groove of the connecting block 6, the friction force on the outer surface of the rotating shaft 2 can be effectively reduced, and the service life of the rotating shaft 2 is effectively improved.
[0034] Specifically, four groups of mounting holes are evenly formed on the second mounting plate 14. Through the arrangement of the four groups of mounting holes, the second mounting plate 14 can be fixedly installed at the desired position.
[0035] Working principle: When using a long-life rotating shaft, first install the first mounting plate 1 and the second mounting plate 14 at different positions through the multiple groups of mounting holes on the first mounting plate 1 and the second mounting plate 14, then remove the two groups of plugs 8 on the upper end of the connecting block 6, and then pour lubricating oil into the two groups of through holes on the upper end of the connecting block 6. After a certain amount of lubricating oil is poured, the two groups of plugs 8 are put into the original positions, and then the nut 3 on one side of the rotating shaft is rotated so that the two groups of clamping rings 4, the two groups of gaskets 5 and a group of connecting blocks 6 are fixed together by a certain pressure, and then the connecting block 6 can start to rotate on the outer surface of the rotating shaft 2. As the connecting block 6 rotates, the buffer structure composed of the multiple groups of movable balls 13 inside the connecting block 6 and the multiple groups of plugs 10, sleeve rods 9 and springs 11 also starts to operate. This is the entire working process of a long-life rotating shaft.
[0036] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
