Abstract

The invention relates to a length variable protective cover. The length variable protective cover comprises a protective cover I; a protective cover II is connected with the outside of the protective cover I in a sleeving mode; a protective cover III is connected with the outside of the protective cover II in a sleeving mode; the protective cover I, the protective cover II and the protective cover III can extend and retract between each other; the sections of the protective cover I, the protective cover II and the protective cover III are U-shaped. According to the length variable protective cover, the structure is simple, the protective cover I, the protective cover II and the protective cover III are connected with each other in a sleeving mode and can extend and retract between each other, the length can be changed freely according to the movement of a workbench, and the protective effect is good.

Description

technical field [0001] The invention relates to the field of grinding machine accessories, especially a variable-length protective cover. Background technique [0002] Grinding machines will produce grinding debris during the working process. In order to prevent the grinding debris from entering the slide rail and causing wear between the workbench and the guide rail, it is usually necessary to install a protective cover on the idle section of the guide rail. However, the protective cover in the prior art is a fixed-length non-retractable structure, and the protective cover cannot freely change the length according to the movement of the workbench. It is inconvenient to use, the protective cover is easily damaged, and the protective effect is not good. Contents of the invention [0003] The technical problem to be solved by the present invention is: in order to overcome the above-mentioned problems, a variable-length protective cover is provided, which can freely change th...
