Abstract
The utility model discloses an extension pipe for a dust collector, and relates to the production field of dust collectors. The extension pipe for the dust collector comprises an inner pipe and an outer pipe, wherein the inner pipe can axially slide inside the outer pipe. The extension pipe is characterized in that a gum cover is arranged on the outside of the inner tube; a limiting groove is formed in the outer wall of the gum cover; a notch is formed in the gum cover; a thread bushing is arranged on the outside of the gum cover; the inner wall of the thread bushing is provided with a first thread; the inner wall of the thread bushing, corresponding to the limiting groove, is provided with a boss; one end of the outer pipe is provided with a second thread; the first thread and the second thread are mutually matched and connected. According to the extension pipe, the inner pipe can be locked at will, so that the positioning flexibility of the extension pipe for the dust collector is improved.
Description
Technical field
The utility model relates to dust catcher production field, relates in particular to a kind of elongated tube of air cleaner.
Background technology
Dust catcher mainly comprises body, suction nozzle and sweep-up pipe, sweep-up pipe is connected between suction nozzle and body, for the ease of helping and control suction nozzle, between sweep-up pipe and suction nozzle, increase the extension tube that one end has rigidity and can shrink, in prior art, by multiple draw-in grooves being set at inner tube length direction according to certain intervals, and complete and extend location object in conjunction with other parts, this kind of method complex structure, locate inflexible (can only locate in the position that has draw-in groove), and processing assembling trouble, complicated structure means increasing of fault rate simultaneously.
