Description
Technical field
The utility model relates to a kind of electric hammer dust guard.
Background technology
Electric hammer is a kind of being mainly used at concrete. floor. and the electric tool of holing on brick wall and the stone material, it is on the basis of electric drill, increased a piston that crankshaft-link rod is arranged by motor drives, reciprocating air in a cylinder, make the cylinder inner air pressure be the cycle variation, the air pressure that changes drives the top that the hammer in the cylinder back and forth hits drill bit, because the drill bit of electric hammer has also produced along the quick reciprocating motion (frequent impact) of the direction of electric drill bar when rotating, so it can punching fast on materials such as big cement concrete of fragility and stone material.And electric hammer is a kind of easy-consumed goods of low value, and foreign trade is sold and then mainly concentrated on America and Europe, Middle East, thereby bigger market development potentiality are arranged.
Yet, in the process that the operation electric hammer is holed, can produce a large amount of dust the staff, particularly when using electric hammer to hole vertically upward, the dust that produces not only can enter the human respiratory tract, and very easily falls into eyes, and the health that has influenced the staff greatly is with healthy; In addition, long-term post-job temperature of diamond bit is higher, very easily human body skin is caused and burns.Therefore, in " electric hammer safety regulation for operations ", stipulated that clearly the electric hammer operating personnel need wear safety goggles and protective face mask, safety operation standard such as note burning during bit change more.But the staff is easy to generate sense of discomfort after wearing corresponding protection tool first, influences operating efficiency; Second the drill bit accident potential such as human body that burns still exists, and therefore, the dust that produces when being badly in need of wanting a kind of can boring to electric hammer is in time collected, and can completely cut off the corollary apparatus of high temperature drill bit again.
The utility model content
The utility model is according to the deficiencies in the prior art, and the dust that has produced when a kind of can work to electric hammer is provided is in time collected, and can completely cut off the electric hammer dust guard of high temperature drill bit again, and the concrete scheme of this electric hammer dust guard is as follows:
A kind of electric hammer dust guard comprises sleeve, and described sleeve is scalable pipe fitting, and described sleeve top is provided with opening, and the outside, described sleeve bottom surface is provided with feet; Described sleeve bottom surface is provided with first manhole, also is fixed with a bearing on the bottom surface in described sleeve, and described bearing is parallel with the sleeve bottom surface, and described bearing and the coaxial setting of described first manhole; In the side of described bearing, be provided with dust cover, and described dust cover is provided with second manhole coaxial with described first manhole towards the sleeve top.
Preferably, the bearing inner sleeve place of described bearing also is provided with the gum sleeve of coupling, because of different-diameter drill bit base diameter is identical, can make the diameter of gum sleeve and drill bit base diameter that higher cohesive is arranged.
Preferably, the opening part of described sleeve also is provided with supporting network, and support frame as described above is provided with three manhole coaxial with described manhole.
Preferably, described supporting network is the bakelite piece.
Preferably, also be provided with seal washer between described bearing and the described dust cover, described seal washer is provided with four manhole coaxial with described first manhole.
Preferably, the opening on described sleeve top is horn-like.
Preferably, the length of described sleeve is not shorter than the electric hammer drill length of being installed.
Use the technical solution of the utility model, the electric hammer dust guard is connected with electric hammer by feet, the drill bit of electric hammer is passed and extends the opening part on sleeve top from the bearing of sleeve bottom surface, the dust that electric hammer produces is in the course of the work collected by sleeve, and because sleeve is with the electric hammer drill and the external isolation of heating, the security that has improved electric hammer.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present utility model, constitutes the application's a part, does not constitute to improper qualification of the present utility model, in the accompanying drawings:
Fig. 1 is the utility model cutaway view;
Fig. 2 is the A-A direction view of the utility model with Fig. 1;
Fig. 3 is the utility model and electric hammer assembling schematic diagram.
The specific embodiment
Describe the utility model in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the utility model in this illustrative examples of the present utility model and explanation, but not as to qualification of the present utility model.
Embodiment 1:
As Figure 1-3, a whole cylindrical sleeve 1, the sidewall of described sleeve 1 is made by the rubber-like plastic material, and also comprises a coil tension spring in sleeve 1 sidewall, makes sleeve 1 integral body possess retractility; Be the top and be provided with opening 2 on the top with an end of sleeve 1; The other end with sleeve 1 is the bottom, and is provided with first manhole at the bottom surface of sleeve 1 mid portion; Be provided with a bearing 3 in sleeve 1 an inner side near the bottom surface, the bearing outside width of this bearing 3 is slightly larger than bearing inner sleeve, and the marginal portion of bearing outside and sleeve 1 bottom surface are tightly connected, and this bearing 3 is coaxial with first manhole; The outside, bottom surface of this sleeve 1 also is provided with the feet of being made by elastic sheet metal 4;
In the side of bearing 3 towards sleeve 1 top, be provided with a tabular dust cover 5, this dust cover 5 and bearing 3 bores coupling, and be tightly connected with the bearing outside edge of bearing 3, in the centre position of dust cover 5, also be provided with second manhole coaxial with first manhole.
During use, the feet 4 of the foregoing description scheme electric hammer dust guard is inserted in connecting ring 8 slits of electric hammer auxiliary-handle 6 and electric hammer hammer body 7, the electric hammer dust guard can be connected with electric hammer, the drill bit 9 of electric hammer passes and extends the opening 2 on sleeve 1 top simultaneously from the bearing 3 of sleeve 1 bottom surface at this moment, adopt the bearing 3 that mates with drill bit 9 bores, bearing 3 and drill bit 9 can be rotated synchronously; And, the space in the sleeve 1 and the drill bit output of electric hammer effectively can be isolated second manhole on the dust cover 5 and drill bit 9 bores coupling.After starting electric hammer, drill bit 9 acts on concrete. floor. and the boring position on brick wall and the stone material, the dust that produce this moment falls into sleeve 1 and is collected; And because the isolation of sleeve 1 makes metapyretic drill bit 9 be difficult for directly touching human body.
