The disclosure relates to a dustproof device, and more particularly to a dustproof device for an electric nail gun.
Referring to
However, since the dustproof cover 13 covers a portion of the machine body unit 11 and also retains the portion of the machine body unit 11, the dustproof cover 13 has to be designed to be relative large, and may block the sight of a user during use of the conventional nail gun 1. Further, a hand tool such as a screw driver is required to tighten or loosen the bolts 14 when assembling the dustproof cover 13 to the machine body unit 11 or disassembling the dustproof cover 13 from the machine body unit 11, which is relatively inconvenient.
Therefore, an object of the disclosure is to provide a dustproof device that can alleviate at least one of the drawbacks of the prior art.
According to the disclosure, a dustproof device adapted for use in an electric nail gun is provided. The electric nail gun includes a magazine unit that is used for accommodating a plurality of nails therein, a muzzle unit that extends in a longitudinal direction, that is connected to the magazine unit, and that is for discharging the nails, and a machine body unit that is connected to the muzzle unit and that is operable to strike the nails. The dustproof device includes a dustproof plate and at least two fastening members. The dustproof plate has a mounting surface that is adapted to face the machine body unit, an exterior surface that is opposite to the mounting surface and that is adapted to prevent foreign matters from entering the machine body unit, and a through hole that extends through the mounting surface and the exterior surface, that is adapted to permit the muzzle unit to extend fittingly therethrough, and that is adapted to be complementary in shape with a contour of a cross section of the muzzle unit. The at least two fastening members extend from the mounting surface of the dustproof plate and are adapted to be detachably connected to the machine body unit to thereby secure the dustproof plate between the machine body unit and the muzzle unit.
Other features and advantages of the disclosure will become apparent in the following detailed description of the embodiment(s) with reference to the accompanying drawings. It is noted that various features may not be drawn to scale.
Before the disclosure is described in greater detail, it should be noted that where considered appropriate, reference numerals or terminal portions of reference numerals have been repeated among the figures to indicate corresponding or analogous elements, which may optionally have similar characteristics.
It should be noted herein that for clarity of description, spatially relative terms such as “top,” “bottom,” “upper,” “lower,” “on,” “above,” “over,” “downwardly,” “upwardly” and the like may be used throughout the disclosure while making reference to the features as illustrated in the drawings. The features may be oriented differently (e.g., rotated 90 degrees or at other orientations) and the spatially relative terms used herein may be interpreted accordingly.

The dustproof device includes a dustproof plate 3 and at least two fastening members 4. In this embodiment, the dustproof device includes four fastening members 4 (see
In this embodiment, the dustproof plate 3 is substantially rectangular, and has a mounting surface 31 that is adapted to face the housing 231 of the machine body unit 23, an exterior surface 32 that is opposite to the mounting surface 31 and that is adapted to prevent foreign matters (e.g., dust) from entering the machine body unit 23, a through hole 33 that extends through the exterior surface 32 and the mounting surface 31 in the longitudinal direction (X), that is adapted to be complementary in shape with a contour of a cross section of the muzzle unit 22, and that is adapted to permit the muzzle unit 22 to extend fittingly therethrough, and a surrounding surface 34 that interconnects the mounting surface 31 and the exterior surface 32, that defines the through hole 33, and that is adapted to be in contact with an outer surface of the muzzle unit 22 in an air tight manner.
In this embodiment, the fastening members 4 extend from the mounting surface 31 of the dustproof plate 3, are disposed respectively adjacent to four corners of the dustproof plate 3, and are adapted to be detachably connected to the machine body unit 23 to thereby secure the dustproof plate 3 between the machine body unit 23 and the muzzle unit 22. Specifically, the fastening members 4 and the dustproof plate 3 are formed integrally, and the fastening members 4 are inseparable from the dustproof plate 3. Each of the fastening members 4 is adapted to protrude from the mounting surface 31 in the longitudinal direction (X) parallel to the muzzle unit 22.
Further referring to
It should be noted that the number of the fastening members 4 is not limited to four, and in other variations of the present embodiment, the number of the fastening members 4 may be two or more than four. In such variations, the number of the through openings 232 of the housing 231 is changed to be the same as the number of the fastening members 4.
To assemble the dustproof device to the electric nail gun 2, the muzzle unit 22 is first brought to extend through the through hole 33 of the dustproof plate 3 and the fastening members 4 are aligned respectively with the through openings 232, then the dustproof plate 3 is pressed toward the housing 231, such that the fastening members 4 respectively extend into the through openings 232 to the extent that the mounting surface 31 is in contact with an outer surface of the housing 231 and the snap-fit halves 41 of each of the fastening members 4 engage the inner surface of the housing 231, so the dustproof plate 3 is secured between the housing 231 and the muzzle unit 22.
In this way, the dustproof plate 3 covers gaps formed between the halves of the housing 231 of the machine body unit 23, and the exterior surface 32 of the dustproof plate 3 prevents foreign matters from entering the machine body unit 23.
To disassemble the dustproof device from the electric nail gun 2, the dustproof plate 3 is simply pulled by a force away from the housing 231, e.g., opposite in the longitudinal direction (X), such that the snap-fit halves 41 of each of the fastening members 4 are forced to deform toward each other to be disengaged from the inner surface of the housing 231, and thus are detached from the respective one of the through openings 232 of the housing 231 during movement of the dustproof plate 3 away from the housing 231.
It should be noted that the dustproof plate 3 is not limited to be used for covering the gaps formed between the halves of the housing 231. In a variation of this embodiment, e.g., as shown in
Additionally, in this variation, the fastening members 4 are spaced apart from each other in a width direction (Y) transverse to the longitudinal direction (X) and the height direction (Z), and extend toward each other along an axis that extends in the width direction (Y). Similarly, each of the fastening members 4 is adapted to extend into the respective one of the through openings 232 formed in the housing 231 of the machine body unit 23 and to engage the inner surface of the housing 231.
By virtue of the configuration of the extension portion 35 of the dustproof plate 3, a region of the electric nail gun 2 covered by the dustproof plate 3 is increased as compared to that covered by the embodiment shown in
Through the above description, the advantages of the embodiment of the present disclosure may be summarized in the following.
First, the dustproof plate 3 of the embodiment shown in
Second, by virtue of the configuration of the fastening members 4 that are resiliently deformable to engage and disengage the housing 231 of the machine body unit 23, it is convenient to assemble and disassemble the dustproof device of the present disclosure without using a hand tool such as a screw driver.
Third, the extension portion 35 of the dustproof plate 3 shown in
In the description above, for the purposes of explanation, numerous specific details have been set forth in order to provide a thorough understanding of the embodiment(s). It will be apparent, however, to one skilled in the art, that one or more other embodiments may be practiced without some of these specific details. It should also be appreciated that reference throughout this specification to “one embodiment,” “an embodiment,” an embodiment with an indication of an ordinal number and so forth means that a particular feature, structure, or characteristic may be included in the practice of the disclosure. It should be further appreciated that in the description, various features are sometimes grouped together in a single embodiment, figure, or description thereof for the purpose of streamlining the disclosure and aiding in the understanding of various inventive aspects; such does not mean that every one of these features needs to be practiced with the presence of all the other features. In other words, in any described embodiment, when implementation of one or more features or specific details does not affect implementation of another one or more features or specific details, said one or more features may be singled out and practiced alone without said another one or more features or specific details. It should be further noted that one or more features or specific details from one embodiment may be practiced together with one or more features or specific details from another embodiment, where appropriate, in the practice of the disclosure.
