perforated dust collector

Abstract

The invention relates to a punching dust collector which comprises a disposable base plate, a dust collection cavity and a telescopic rubber cavity, wherein a drill bit hole for enabling a drill bit to penetrate through is formed in the middle part of the disposable base plate; four hooks clamped with the dust collection cavity are arranged on the inner side of the disposable base plate; more than three positioning bosses are uniformly arranged around the drill bit hole; positioning through holes are formed in the middle parts of the positioning bosses; a sealing lip is arranged on the outer side of the disposable base plate; the dust collection cavity is a barrel-shaped body; combination openings clamped with the hooks are formed in the opening in one end of the barrel-shaped body; a clamping rim matched with the telescopic rubber cavity is arranged at the opening in the other end of the barrel-shaped body; an impurity guide opening is formed in the barrel wall of the lower part of the barrel-shaped body; the telescopic rubber cavity is a waveform barrel-shaped body; an annular clamping ring sleeving the sealing lip is arranged at the opening in one end of the waveform barrel-shaped body; an anti-abrasion ring is arranged at the opening in the other end of the waveform barrel-shaped body and covers the outer wall of the drill bit. The punching dust collector is simple in structure and can thoroughly prevent escape of dust or muddy water and protect the living environment and the health of an operator.

Description

technical field [0001] The invention relates to the technical field of electric tool accessories, in particular to a perforated dust collector. Background technique [0002] At present, there is no dust-proof drilling in the drilling process of the installation project. When drilling, there will be various headaches such as muddy water flow or dust flying, which not only poses health threats to operators, but also pollutes the living environment. Especially for houses that have been renovated, it is very troublesome to clean up, which will affect the image of the installation company. Chinese patent literature [announcement date: August 15, 2012, announcement number: CN202380691U] discloses a special drilling device for building decoration construction. The drilling device includes a drilling rig on which a drill bit is clamped, and also includes a bracket and a feed rod. , the feed rod is vertically set on the machine support through the guide device, the bottom end of the...

Problems solved by technology

Although the above technical solution has an annular sealing lip at the front end of the hose, there is no problem in drilling holes on the ground, but there is inevitably a gap between the annular sealing lip and the wall during the process of drilling holes in the wall or ceiling. Dirt or muddy water will still seep through here
