Abstract

The utility model discloses a dust arrester is bored to disposable impact, dust arrester are the cup cover body, cover body upper portion opening, and the bottom lock, it is protruding that cover body bottom central authorities inwards are equipped with the round platform form, and the edge is cyclic annular sunken, and open at the bottom center has the perforation that supplies the drill bit to pass, the bore of cover body upper portion open end is from up reduce down gradually. The beneficial effects of the utility model reside in that, can collect the dust that churn drill bit drilled out effectively and strike brill dust arrester the inside, the dust that the drill bit drilled out can not fly upward everywhere, and this device convenient to use, simple structure, low cost.

Description

Dust arrester is bored in a kind of disposable impact

Technical field

This utility model relates to dust guard field, particularly relates to a kind of disposable impact and bores dust arrester.

Background technology

In the various engineering such as architectural engineering, house ornamentation engineering are built, hand-held hammering drill is a kind of portable boring specific purpose tool.When operator use the impact drilling at present, the most not collecting the device of flying dust, the dust got out flies upward everywhere, causes damage the health of operator, additionally working space completely dust.

Utility model content

The purpose of this utility model is to solve shortcoming present in prior art, and proposes disposable impact and bore dust arrester.

To achieve these goals, this utility model adopts the technical scheme that

Dust arrester is bored in a kind of disposable impact, and dust arrester is cup-shaped mask body, cover body upper opening, bottom lock, and cover body bottom center is provided inwardly with round table-like projection, and edge is annular recess, and bottom centre has the perforation passed for drill bit；The bore of cover body upper, open end is gradually reduced from the bottom up.

Preferably, cover body upper, open end and covers body are separable assembly, and both are by glue or are threaded togather.

The beneficial effects of the utility model are, the dust that chopping bit gets out can be efficiently collected in impact and bore inside dust arrester, and the dust that drill bit gets out will not fly upward everywhere；And this device is easy to use, simple in construction, with low cost.

Accompanying drawing explanation

Fig. 1 is overall structure schematic diagram of the present utility model.

Fig. 2 is the structural representation of another embodiment of this utility model.

Fig. 3 is the schematic diagram that in Fig. 2, embodiment covers body is nested together.

Detailed description of the invention

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.

With reference to Fig. 1, dust arrester is bored in a kind of disposable impact, and dust arrester is cup-shaped mask body 1, cover body top 2 opening, and bottom 3 is closed, and cover body bottom center is provided inwardly with round table-like protruding 4, and edge is annular recess 5, and bottom centre has the perforation 7 passed for drill bit 6；The bore of cover body upper, open end is gradually reduced from the bottom up.

In another embodiment, as in figure 2 it is shown, cover body upper, open end and covers body are separable assembly, both are by glue or are threaded togather.Covers body, when transport, is separated by product with upper, open end, together with multiple covers body are respectively fitted over upper, open end, as shown in Figure 3, it is possible to reduce the volume that product takies in transportation.

In use, operator one are held by disposable impact and bore dust arrester this utility model, hold the impact that can work on the other hand and bore；Drill bit is bored the hole bottom dust arrester through impact, then point to be holed in drill bit perpendicular alignmnet plane, then disposable impact is bored the opening pressure of dust arrester in the plane；Adjust impact and bore the hole bottom dust arrester and the position of drill bit shaft, make hole and drill bit shaft keep certain gap；Then boring is started, when bit operation position horizontal and vertical upwards between 90 degree of scopes time, the dust that chopping bit gets out can be efficiently collected in impact and bore inside dust arrester by it, the dust that drill bit gets out will not fly upward everywhere, owing to the hole bottom dust arrester and drill bit shaft have certain gap, have few dust to spill from gap location, but do not interfere with the work of operator.When drill bit is holed vertically downward, dust arrester is bored in impact can not collect dust, but can control dust and fly upward the most everywhere.

When have collected more dust in disposably dust arrester is bored in impact, hand-held impact bores so that chopping bit and dust arrester vertically upward, take out dust arrester along chopping bit bar, then the dust inside dust arrester is most.

Disposable dust arrester of the present utility model, profile can be cup shape revolving body, it is also possible to be other curved bodies.Its top and bottom protrusion can be funnel shaped, and funnel shaped is easy to collect flying dust, at the bottom of dust is collected into glass along funnel inclined-plane.

The above; it is only this utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; any those familiar with the art is in the technical scope that this utility model discloses; conceive equivalent or change in addition according to the technical solution of the utility model and utility model thereof, all should contain within protection domain of the present utility model.

Claims
