technical field

The utility model relates to a linear sliding rail, in particular to a dustproof piece for the linear sliding rail and a linear sliding rail having the dustproof piece.

Background technique

A general linear slide rail will be provided with a dust-proof part inside the slider, and the dust-proof part will prevent foreign objects (such as dust or oil) from entering the interior of the slider, which will adversely affect the operation of the rolling elements. The upper dustproof element disclosed in the Patent No. I598519 of Taiwan Bulletin has a main body and two engaging parts extending from the main body to both sides. It is located in the engaging groove of the slider module and has a contact end which is in contact with the fixing protrusion of the rail. In addition, the body also has two dust-proof lips, and the end of each dust-proof lip is in contact with the upper surface of the rail. However, the above-mentioned upper dustproof element needs to be removed from the slider such as the end cover and the oil scraper when installing, and then the external accessories such as the end cover and the oil scraper should be re-installed on the slider after the installation is completed. Therefore, it can be seen that the above-mentioned existing upper dustproof element is quite inconvenient to use.
