Abstract
The utility model discloses an electro-drill dust cover which adopts a cylindrical structure as a whole, the end surface of one end of the dust cover is open-ended and is in tight fit with a processed surface, and a drill bit hole is formed in the end surface of the other end of the dust cover and is fixed with an electro-drill main body in a matched manner. The dust cover is characterized by comprising a cylindrical outer cover, an inner sleeve and an observation cover, wherein the cylindrical outer cover and the inner sleeve are connected together through a spline in a matched manner; the cylindrical outer cover can move forwards and backwards in the axial direction of the inner sleeve; the inner sleeve is in threaded connection with and fixed on a non-rotary neck part of a head part of the electro-drill main body. The dust cover has the advantages of simple structure, convenience and practicability, avoids flying dust in the operation process and also avoids environment pollution, so that an effective guarantee is provided for the body health of an operator, and the surrounding environmental sanitation is protected.
Description
Technical field
The utility model relates to a kind of and the matching used annex of electric drill, particularly a kind of dust-proof cover for electric drill.
Background technology
At present, in actual mechanical process, electric drill is when holing to surface to be machined, a large amount of dusts rises from all around all over the sky often, broken end is deeply unrestrained to ground from discharging the helicla flute of drill bit along with drill bit also, the environment around having polluted, and the operator also sucks a large amount of dusts all over the body when dust, the health worked long hours to the operator has brought great harm, and on existing electric drill, often is not equipped with dust guard.
Summary of the invention
The utility model is for the proposition of above problem, and Development and design a kind of novel electric drill annex, i.e. a kind of dust-proof cover for electric drill.The global shape of this dust-proof cover for electric drill is tubular structure, and the end face of an end is open, is close to surface to be machined, and the other end is provided with drill bit bore, and is fixed with drill body.It is characterized in that: comprise the tubular outer cover, inner sleeve and viewing hood.Described tubular outer cover and inner sleeve link together by the form of spline fitted structure, and the axial direction that the tubular outer cover can prolong inner sleeve moves forward and backward.The mode that inner sleeve is threaded connection is fixed on the non rotatable neck of drill body head.
On the side of described inner sleeve, be carved with the graduation indication arrow, on viewing hood, be carved with scale, described viewing hood is made of transparent material.
Adopted the following advantage of the utlity model has of technique scheme:
1, the utility model is the annex of electric drill, and electric drill work the time has avoided dust to rise from all around, and contaminated environment, for operating personnel healthy provides effective guarantee, prevents contamination by dust, thereby also alleviated after operation completes the workload of clearing up of bringing.
2, the utility model is when the electric drill operation, the operator often needs to know that drill bit pierces the accurate degree of depth of surface to be machined, the utility model is gone up and also has been equipped with the graduation indication function at dust cover simultaneously, can accurate quick read the degree of depth that drill bit pierces surface to be machined.
The accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present utility model;
Fig. 2 is side-looking cross-sectional view of the present utility model;
Fig. 3 is that master of the present utility model looks cross-sectional view.
The number in the figure explanation:
1. tubular outer cover; 2. inner sleeve; 3. drill body; 4. viewing hood; 5. drill bit.
The specific embodiment
As accompanying drawing 1, Fig. 2 and dust-proof cover for electric drill structure shown in Figure 3, comprising: the global shape of dust-proof cover for electric drill is tubular structure.The end face of one end is open, and is close to surface to be machined, and the other end is provided with drill bit bore, is fixed with drill body 3.Tubular outer cover 1 and inner sleeve 2, the form by the spline fitted structure links together, and the axial direction that tubular outer cover 1 can prolong inner sleeve 2 moves forward and backward.The mode be threaded connection is fixed on inner sleeve 2 on the non rotatable neck of electric drill head, namely is fixed on drill body 3.
On the surface of tubular outer cover 1, have a rectangular hole, and with glue, viewing hood 4 is sealed rectangular hole, viewing hood 4 adopts transparent material to make, for the operator can observe the working condition of drill bit 5 in operation process.
Because inner sleeve 2 and drill body 3 are connected and fixed, so inner sleeve 2 is actionless with respect to drill body 3 at work.On the side of inner sleeve 2, be carved with the graduation indication arrow, be carved with scale on viewing hood 4.Before processing, the open end of drill bit 5 tips and tubular outer cover 1 is contacted respectively simultaneously with surface to be machined.Electric drill in the course of the work along with drill bit 5 gradually be deep into surface to be machined, tubular outer cover 1 is prolonging drill bit 5 and enters the opposite direction of surface to be machined and back away simultaneously.Now tubular outer cover 1 also retreats with respect to inner sleeve 2 on the axial direction of drill bit 5, and the distance retreated is exactly namely the degree of depth that drill bit 5 is drilled into surface to be machined.Now at the arrow on inner sleeve 2, refer to that the reading on the graduation mark on viewing hood 4 is exactly the degree of depth that drill bit 5 pierces surface to be machined, simultaneously may reading numerical values.
Because inner sleeve 2 and drill body 3 are threaded togather, in the idle situation of electric drill, for the volume that reduces electric drill, easy to carry, dust cover can be pulled down, during work, again dust cover is screwed to assembling is upper to be got final product.
The above; it is only the preferably specific embodiment of the utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; according to the technical solution of the utility model and inventive concept thereof, be equal to replacement or changed, within all should being encompassed in protection domain of the present utility model.
Claims (2)
