It is a kind of common electric tool that electric hand drill (impacts brill, electric screwdriver etc.), it is simple to carrying and use flexibly, cost performance is also higher, applies wide.In actual use, it may appear that work surface is higher than operator's situation even on surface, such as roof ceiling positional punch.In this case in operation process, operator does not only exist in the state of looking up and stands on ladder, and chip, dust etc. can vertically fall, produce to hinder to operator's sight line, it may occur however that position, hole position error is big, operator surprisingly falls and flies away the situation of contaminated environment with dust.
For the problems referred to above, it is necessary to existing electric hand drill structure is improved so that it is have dust reduction capability and dust collection function, the sight line stopping operator can being avoided to bring danger, thus improving drilling quality and safety, and reducing the pollution to construction environment.
Summary of the invention
In view of this, the purpose of this utility model is in that to provide a kind of dustproof electric hand drill, to solve the quality instability that prior art exists in drilling operation, the problem that there is pollution and potential safety hazard.
For reaching above-mentioned purpose, this utility model provides following technical scheme:
A kind of dustproof electric hand drill, including electric hand drill, also include the movable dust cover being set on drill bit, described dust cover is that transparent material is made, including the fixing parts of drill bit and the dust-collection element being arranged on the fixing parts one end of drill bit, the fixing parts of described drill bit include barrel shrond, it is fixed on the drill bit centring sleeve of the rolling bearing in barrel shrond and the bore area being fixed on rolling bearing, the described bore area of drill bit centring sleeve and the outer round surface of drill bit are adjacent to formation and seal, described dust-collection element is the sealable bowl-type lid being adjacent on operation element face that an employing elastomeric material is made.
Further, described dust cover also includes the extensible member connecting the fixing parts of drill bit and dust-collection element, and described extensible member is one section of Flexible pipe fitting or screwed fittings.
Further, described barrel shrond is provided with for stopping the catch that dust is overflowed between rolling bearing and extensible member, and described catch is provided with the drill bit via being slidably matched with drill bit.
Further, the upstream end of described drill bit centring sleeve is provided with drill bit entrance tapering.
Further, also including dust evacuation system, described dust evacuation system includes dust conduit and air pump, and described dust conduit connects with dust cover inner chamber and air pump respectively.
The beneficial effects of the utility model are in that:
The drill bit of electric drill can be positioned by this utility model by the fixing parts of drill bit, thus ensureing borehole accuracy and quality, with dust-collection element, boring dust is collected, it is to avoid produce to pollute to human body, danger is brought, thus improving the safety of boring with the sight line stopping operator.
Other advantages of the present utility model, target and feature will be illustrated to a certain extent in the following description, and to a certain extent, will be apparent to those skilled in the art based on to investigating hereafter, or can be instructed from practice of the present utility model.Target of the present utility model and other advantages can be realized by description below and obtain.
Accompanying drawing explanation
In order to make the purpose of this utility model, technical scheme and beneficial effect clearly, this utility model provides drawings described below to illustrate:
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the sectional view of the fixing parts of drill bit.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
As shown in the figure, a kind of dustproof electric hand drill in the present embodiment, including electric hand drill 10, also include the dust cover 1 on the movable drill bit being set in electric hand drill 10, described dust cover 1 is made for transparent material, operating process can be observed, ensure that operating process is visual, it includes the fixing parts of drill bit and is arranged on the dust-collection element of the fixing parts one end of drill bit, the fixing parts of described drill bit include barrel shrond 2, it is fixed on the drill bit centring sleeve 4 of the rolling bearing 3 in barrel shrond 2 and the bore area being fixed on rolling bearing 3, the described bore area of drill bit centring sleeve 4 and the outer round surface of drill bit are adjacent to formation and seal, dust is avoided to overflow in cover, described dust-collection element is the sealable bowl-type lid being adjacent on operation element face that an employing elastomeric material is made, can fully fit with metope, improve sealed horizontal.
The drill bit of electric drill can be positioned by the present embodiment by the fixing parts of drill bit, thus ensureing borehole accuracy and quality, with dust-collection element, boring dust is collected, it is to avoid produce to pollute to human body, and stops that the sight line of operator brings danger, thus improving the safety of boring, make it addition, dust cover is transparent material, it is possible to operating process is observed, ensure that operating process is visual, be further ensured that drilling quality.
Further, described dust cover also includes the extensible member 5 connecting the fixing parts of drill bit and dust-collection element, and described extensible member 5 is one section of Flexible pipe fitting or screwed fittings, improves the elastic range of dust cover, compensate the amount of piercing of drill bit in boring procedure, be beneficial to the sealing of boring overall process.
Further, described barrel shrond is provided with for stopping the catch 8 that dust is overflowed between rolling bearing and extensible member, described catch 8 is provided with the drill bit via 9 being slidably matched with drill bit, the present embodiment can make catch 8 with elastomeric material, less drill bit via can be set, improve the level that coordinates with drill bit, and then improve sealed horizontal.
Further, the upstream end of described drill bit centring sleeve is provided with drill bit entrance tapering 6, facilitates drill bit to rapidly enter, and improves drilling efficiency.
Further, also including dust evacuation system, described dust evacuation system includes dust conduit 7 and air pump, described dust conduit connects with dust cover inner chamber and air pump respectively, by air pump, dust is taken away, it is to avoid the dust pollution to human body and environment, improve the cleannes of working region.
What finally illustrate is, preferred embodiment above is only in order to illustrate the technical solution of the utility model and unrestricted, although this utility model being described in detail by above preferred embodiment, but skilled artisan would appreciate that, in the form and details it can be made various change, without departing from this utility model claims limited range.
