Description

Electric hammer dust cover

Technical Field

The utility model relates to an electric hammer accessory field especially relates to an electric hammer dust cover.

Background

Electric hammers are common tools used in construction and decorative engineering. When a worker drills a hole to the top, the dust which is drilled can fly around without a dustproof device, so that the operation is not only hindered, but also the sanitation and health of the worker are damaged. Common electric hammer dust cover is for putting bottle lid form or loudspeaker form in the china market at present, makes with rubber, and it is cheap, but dustproof effect is not good, and in the use, the dust cover receives the extrusion, and the space of collecting dust diminishes, and rubble and waste residue persist in fold department, can hinder the use of electric hammer.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that overcome exist among the prior art not enough, provide an electric hammer dust cover, it has dustproof effectual and the unchangeable advantage in collection dirt space.

The utility model discloses a realize through following technical scheme: the utility model provides an electric hammer dust cover, includes electric hammer body and drill bit, the electric hammer body is close to drill bit department and is fixed with the lantern ring, has horizontal spring support device through the screw fixation on the lantern ring, spring support device's extreme point department is fixed with the dust cover, the both sides of dust cover are equipped with the rotatory hole and the working hole that supply the drill bit to pass respectively, spring support device includes first bracing piece and second bracing piece, be fixed with between first bracing piece and the second bracing piece and cup joint the spring on first bracing piece and second bracing piece, the dust cover is fixed on first bracing piece.

Furthermore, a dust collecting box is fixedly communicated with the dust cover, and the lower end of the dust collecting box is connected with a sealing cover in a threaded manner.

Furthermore, three groups of spring supporting devices are arranged and are uniformly fixed on the lantern ring.

Furthermore, a sealing rubber pad is arranged at the rotating hole.

Further, the dust cover is made of hard transparent plastic.

The utility model has the advantages that: like this when needs punch, at first fix spring support device on the lantern ring through the screw, make the dust cover butt on the wall this moment, make electric hammer work, the spring can take place deformation when electric hammer drilling is deep to make the dust cover contact with the wall all the time, the dust cover can not take place deformation like this, so the collection dirt space is unchangeable, rubble and waste residue can not remain and make dustproof effect better in fold department.

Drawings

Fig. 1 is a schematic front view of the present invention;

FIG. 2 is a schematic side view of the collar of the present invention;

in the figure: 1. an electric hammer body; 2. a drill bit; 3. a collar; 4. a dust cover; 5. a first support bar; 6. a second support bar; 7. a spring; 8. a dust collecting box; 9. a sealing cover; 10. and sealing the rubber gasket.

Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.

As shown in the figure, the utility model discloses an electric hammer body 1 and drill bit 2, electric hammer body 1 is close to drill bit 2 department and is fixed with the lantern ring 3, has horizontal spring 7 strutting arrangement through the screw fixation on the lantern ring 3, spring 7 strutting arrangement's extreme point department is fixed with dust cover 4, the both sides of dust cover 4 are equipped with rotatory hole and the working hole that supplies drill bit 2 to pass respectively, spring 7 strutting arrangement includes first bracing piece 5 and second bracing piece 6, be fixed with the spring 7 who cup joints on first bracing piece 5 and second bracing piece 6 between first bracing piece 5 and the second bracing piece 6, dust cover 4 is fixed on first bracing piece 5.

Like this when needs punch, at first fix spring 7 strutting arrangement on lantern ring 3 through the screw, make dust cover 4 butt on the wall this moment, make electric hammer work, spring 7 can take place deformation when electric hammer drilling is deep to make dust cover 4 contact with the wall all the time, dust cover 4 can not take place deformation like this, so the collection dirt space is unchangeable, rubble and waste residue can not remain and make dustproof effect better in fold department.

Furthermore, a dust collecting box 8 is fixedly communicated with the dust cover 4, and a sealing cover 9 is connected to the lower end of the dust collecting box 8 in a threaded manner. Therefore, when drilling, the broken stones and waste residues in the dust cover 4 can be timely discharged into the dust collecting box 8 below, the broken stones in the dust cover 4 cannot be excessive, and the broken stones can be poured out by unscrewing the sealing rod, so that the dust collecting box is convenient to use.

Furthermore, three groups of spring 7 supporting devices are arranged, and the three groups of spring 7 supporting devices are uniformly fixed on the lantern ring 3. This can increase the stability of the dust cap 4 when the bore is extended.

Further, a sealing rubber pad 10 is arranged at the rotating hole. The broken stones can be prevented from flying out from the rotating holes.

Further, the dust cover 4 is made of hard transparent plastic. The dust cover 4 can not be broken by gravel and the like, and the practical working condition of drilling can be observed, so that the smooth drilling is ensured.

The utility model has the advantages that: like this when needs punch, at first fix spring 7 strutting arrangement on lantern ring 3 through the screw, make dust cover 4 butt on the wall this moment, make electric hammer work, spring 7 can take place deformation when electric hammer drilling is deep to make dust cover 4 contact with the wall all the time, dust cover 4 can not take place deformation like this, so the collection dirt space is unchangeable, rubble and waste residue can not remain and make dustproof effect better in fold department.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
