Description

Dust collecting device

Technical Field

The utility model relates to a dust collecting device, especially a dust collecting device who is used in on electronic drilling tool.

Background

Electric drilling tool is very general in daily life's application, and the life of giving people has brought very big facility, but electric drilling tool has produced a large amount of dusts in the use simultaneously, causes not good user experience, adopts dust collecting device to be the most common electric drilling tool collection dirt method, and current dust collecting device generally covers the rotatory head at drilling tool, and use collection dirt effect is not very ideal, and dust collecting device and drilling tool make it have the poor scheduling problem of compatibility for fixed collocation.

Disclosure of Invention

The to-be-solved technical problem of the utility model is: the problem of poor universal matching performance of the existing dust collecting device is solved.

In order to solve the above problem, the technical scheme of the utility model is to provide a dust collecting device, its characterized in that: including collection dirt seat and collection dirt sleeve pipe, the one end and the collection dirt bushing joint of collection dirt seat, the other end is equipped with the bearing with the rotatory head contact of electric drilling tool front end, is equipped with clamping mechanism on the collection dirt seat for the axial fixity of dust collecting device during operation.

Preferably, a plug is arranged at one end of the dust collecting seat, which is in contact with the electric drilling tool.

Preferably, the end face of the bearing is provided with a bearing dust cover.

Preferably, a sleeve is arranged on the inner side of the bearing for adjusting the inner diameter of the bearing.

Preferably, the dust collection sleeve is a bellows.

Preferably, one end of the corrugated pipe is connected with the dust collecting base, and the other end of the corrugated pipe is provided with an anti-abrasion ring.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses dust collecting device adopts built-in bearing, realizes the preceding end face contact of dust collecting device and the rotatory head of electronic drilling tool front end, realizes dust collecting device's centering through the cooperation with electronic drilling tool drill bit, and the installation is used portably, has improved dust collecting device's logical match nature greatly.

Detailed Description

In order to make the present invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.

As shown in fig. 1 and 4, the utility model relates to a dust collecting device includes dust collecting base 1 and dust collecting sleeve, and the one end and the dust collecting sleeve of dust collecting base 1 are connected, and bearing 5 is installed to the other end, and bearing shield 8 is installed to the terminal surface of bearing 5, and the inboard installation sleeve 6 of bearing 5 is used for adjusting the internal diameter size of bearing 5. The clamping mechanism 3 is installed on the side surface of the dust collecting base 1, and when the dust collecting device works, the clamping mechanism 3 clamps a component on the electric drilling tool to axially fix the dust collecting device. The end of the dust collecting seat 1, which is contacted with the electric drilling tool, is provided with a plug 4, the size and the shape of the plug 4 are matched with the port of the dust collecting seat 1, and the plug 4 is fixedly connected with the dust collecting seat 1 through a flexible material. The dust collecting sleeve adopts a corrugated pipe 2, one end of the corrugated pipe 2 is connected with the dust collecting seat 1, and the other end is provided with an anti-abrasion ring 7 for preventing abrasion.

As shown in fig. 2 and fig. 3, when in use, the plug 4 is firstly detached, one end of the dust collecting base 1, which is provided with the bearing 5, is contacted with the front end face of the front rotating head part of the electric drilling tool, the drill bit 10 of the electric drilling tool extends into the dust collecting base 1 and the corrugated pipe 2 to realize the centering of the dust collecting device, the sleeve 6 in the bearing 5 can adjust the inner aperture size of the bearing 5, the bearing 5 and the electric drilling tool drill bits 10 with different sizes are conveniently matched and installed, and the universal matching performance of the dust collecting device is improved; and then the depth gauge 9 on the electric drilling tool is clamped by the clamping mechanism 3 on the side surface of the dust collecting seat 1 to realize the axial fixation of the dust collecting device, and the dust is prevented from leaking by the corrugated pipe 2 to realize the dust collecting function.
