Screen shaft with self-lubricating mechanism and method thereof

Abstract

The invention discloses a screen shaft with a self lubricating mechanism and a processing method thereof. The screen shaft comprises a first shaft body, a second shaft body, a third shaft body and twoguide rings, wherein one end of the first shaft body is connected with one end of the second shaft body through one guide ring; the other end of the second shaft body is connected with the third shaft body through the other guide ring; the two guide rings are used as the contact position parts of the screen shaft and the external connection component; a self lubricating mechanism is arranged in each of the two guide rings; through the self lubricating mechanism, the slidable performance is maintained by of the outer side of the guide ring is maintained; an oil guide wire is formed by windingfive identical cotton wires; the oil guide wire forms self drainage on of the lubricating oil in the an oil storage groove. The processing method of the screen shaft uses the sand blasting and multi-time heat treatment; so that the ideal performance can be reached; meanwhile, the shaft body and the guide ring uses friction welding; , so that the energy consumption is low; , the welding performanceis good; and the connecting surface appearance is attractive; the installed oil guide wire performs long effect self lubrication on the guide rings; , so that the maintenance period of the screen shaft is increased to a great degree.

Description

technical field [0001] The invention relates to the related technical field of notebook accessories, in particular to a screen shaft with a self-lubricating mechanism and a processing method thereof. Background technique [0002] The screen shaft is a kind of rotating shaft, which is used to connect the notebook screen and the notebook body. The two ends of the screen shaft are respectively supported by a screen shaft bracket to connect the notebook screen and the notebook body. [0003] In the prior art, the structure of the screen shaft is simple, and the screen shaft is an ordinary rotating shaft. When the notebook screen is flipped, the notebook screen drives the screen shaft to flip, and the contact part between the screen shaft and the external parts will produce a lot of friction. It will reduce the service life of the screen shaft. In the prior art, the external parts (screen shaft bracket) are generally oiled to maintain the performance of the screen shaft and prolo...

Problems solved by technology

[0003] In the prior art, the structure of the screen shaft is simple, and the screen shaft is an ordinary rotating shaft. When the notebook screen is flipped, the notebook screen drives the screen shaft to flip, and the contact part between the screen shaft and the external parts will produce a lot of friction. It will reduce the service life of the screen shaft. In the prior art, the external parts (screen shaft bracket) are generally oiled to maintain the performance of the screen shaft and prolong the service life of the screen shaft. However, this method is relatively It is cumbersome, and for the screen shaft body, there is a certain lubrication effect in a short period of time, but the long-term lubrication effect is not good, so we propose a screen shaft with a self-lubricating mechanism to solve the above problems
