电钻集尘装置 技术领域
本发明关于一种应用于电钻集尘装置， 更详而言之， 尤指一种可活动装卸于 电钻上的集尘装置， 其可适用于各种尺寸型态的电钻， 而无须改变电钻本身的结 构设计， 并具有体积小、 使用方便， 以及结构简单的特性。 背景技术
按， 目前工业或室内装潢业中， 电钻机的用途极为广泛， 用以在壁面钻孔以 从事安装电线或方便螺钉等的钉入， 亦或用于天花板上安装吊灯、 吊扇等时的钻 孔， 利于固接元件将灯扇固定于天花板上。 于钻孔过程中， 难免会产生尘屑， 而 有鉴于集中清理上的便利， 因此市面上一些电钻机于机台侧边加设一外挂式集尘 装置， 其利用吸尘器原理， 以一吸尘管连接钻头与集尘盒或集尘袋， 以达到吸尘 及集尘的效果。
然而， 虽然习用电钻机所额外装设的集尘装置， 确可达到集尘的目的， 但由 于其结构相当复杂， 且需改变电钻机的本身结构， 而体积及重量上皆大幅提高， 因此不仅造成携带及使用上的不便， 亦使得成本大幅增加， 并反应于售价上， 使 得售价相对偏高， 故其使用上并不普遍， 导致钻孔时并无有效的防尘措施， 顶多 仅于地上铺设防尘布， 但仍会造成尘屑四处飞扬及散落防尘布， 不仅造成环境污 染， 并有清理上的不便性。 发明内容
本发明的目的在于提供一种电钻集尘装置， 其结构更加简单， 体积和重量较 轻， 便于携带和实用， 不但集尘效果更好， 且能进一步降低成本。
为实现上述目的， 本发明公开了一种电钻集尘装置， 其特征在于包括： 一中空壳体， 于顶端设有一锥形部， 该锥形部上设有一开孔， 该中空壳体于 底端设有一穿孔， 且该穿孔于外周缘延伸凸设一容置槽；
一中空轴杆， 穿设于该穿孔， 该中空轴杆上轴设至少一轴承， 使该轴承可枢 转地设于该容置槽内；
一弹簧件， 套设于该中空轴杆上； 以及
一隔离件， 连接于该弹簧件的末端， 其设有一圆孔， 以供一钻头穿设， 并使 其贯穿于中空轴杆及开孔；
藉此， 一电钻于钻孔过程中时， 使产生的尘屑可沿锥形部的锥度落入集中于 该中空壳体内。
其中， 该中空壳体呈透明状。
其中， 该中空壳体由一座体及一盖体相互盖合而成， 该锥形部设于该盖体顶 端， 而该穿孔设于该座体上。
其中， 该容置槽于末端处朝内转折延伸设有多个内凸缘， 以供卡置固定该轴 承。
其中， 该中空轴杆上套设有至少一轴套， 该轴套内设有一弹性垫片， 该弹性 垫片上设有多个通过轴心且未延伸至弹性垫片边缘的切割痕， 使该弹性垫片轴心 处可弹性开启以夹持该钻头。
其中， 该中空轴杆上设有至少一螺纹段供螺合该轴套。
其中， 该轴套的设置数量为二， 以分别设于中空轴杆的前后两端， 且位于相 对该弹簧件一侧的轴套于末端设有一中空状的延伸轴杆， 以供套设该弹簧件。
其中， 该弹簧件的另一端系套设于该隔离件内侧延伸设置的一中空杆上。 其中， 该延伸中空轴杆与该中空杆上分别设有一螺纹段。
其中， 该隔离件为一矩形板体。
通过上述结构， 本发明能实现以下技术效果：
一、 在于将该中空壳体紧贴于墙面或天花板， 藉电钻机的运作， 该弹簧件会 产生压缩的力量， 而该中空壳体仍静止不动， 使得产生的尘屑可经由开孔并沿锥 形部的锥度落入集中于该中空壳体内， 以达到集尘的效果， 并确保尘屑不会产生 外漏的情形。
二、 在于藉由该轴承的设置， 使得该钻头于转动时， 并不会带动该中空壳体 产生同步转动， 因此并不会造成中空壳体内的尘屑产生四溅而造成清理上不便， 且亦可避免长期使用下， 该中空壳体因转动而与墙面或天花板产生摩擦， 而造成 中空壳体损坏， 或墙面、 天花板磨损的情形。
三、 在于该轴杆上套设有二弹性垫片， 该弹性垫片上设有多个通过轴心且未 延伸至弹性垫片边缘的切割痕， 使该弹性垫片轴心处可弹性开启， 以供钻头穿设， 藉由二弹性垫片的设计， 除可增加防尘效果外， 并具有平衡钻头与中空壳体的功 用， 避免因失衡而造成中空壳体产生晃动而影响集尘效果。
四、 在于透过该等弹性垫片上该等切割痕的设计， 以供紧密地夹持各种不同 规格的钻头， 使本发明可适用于各种尺寸规格、 厂牌的电钻机及钻头， 因此可提 高使用上的效益， 且对于制造商而言， 无需为配合不同电钻机或钻头而制造出不 同规格， 因此可大幅地降低制造成本。
五、 在于可直接连同电钻机将中空壳体内的尘屑朝下倒出， 利用弹性垫片夹 持钻头时所产生的抓力， 使得尘屑倒出时， 不致于使集尘装置产生向下滑落的情 附图说明

为便于说明本发明于上述发明内容一栏中所表示的中心思想， 兹以具体实施 例表达。 实施例中各种不同物件系按适于说明的比例、 尺寸、 变形量或位移量而 描绘， 而非按实际元件的比例予以绘制， 合先叙明。 且以下的说明中， 类似的元 件是以相同的编号来表示。
如图 1至图 3所示， 本发明为一种电钻集尘装置， 装设于一电钻机 60 (如图 4所 示)前端， 用以集中使用时所产生的尘屑， 其主要包括一中空壳体 10、 一中空轴杆 20、 一弹簧件 30， 以及一隔离件 40， 以供一钻头 61穿设。
该中空壳体 10呈透明状， 以供方便观察该钻头 61及钻孔位置； 其由一座体 11 及一盖体 12相互盖合而成， 其中， 两者的接合方式无特定的限制， 例如可以螺合 方式螺合， 亦或以凹凸方式嵌合固定； 该座体 11呈圆盘状， 其于底端设有一穿孔 111， 该穿孔 111于外周缘延伸凸设一容置槽 112， 该容置槽 112可与该座体 11为一 体成型， 亦或可接设于该穿孔 111外侧， 该容置槽 112于末端处朝内转折延伸设有 多个内凸缘 113; 该盖体 12概呈圆锥状， 其于顶端设有一锥形部 121， 该锥形部 121 上设有一开孔 122， 该开孔 122的孔径需大于习用各种规格的钻头直径。
该中空轴杆 20穿设于该穿孔 111， 且该中空轴杆 20上设有至少一螺纹段 21， 该 中空轴杆 20上分别于螺纹段 21的前后两端套设有至少一轴套 22、 23， 以藉该螺纹 段 21与该等轴套 22、 23相互螺合固定， 各轴套 22、 23内嵌设有一弹性垫片 24， 该 弹性垫片 24可为橡胶材质，其上方设有多个通过轴心的切割痕 241，例如可呈「米」 字状， 且该切割痕 241并未延伸至弹性垫片 24的边缘处， 使该弹性垫片 24轴心处可 弹性开启； 位于相对该中空壳体 10另一侧的轴套 23于末端设有一中空状的延伸轴 杆 25， 该延伸轴杆 25上设有至少一螺纹段 251， 其中， 该轴套 23与该延伸轴杆 25的 接合方式无特定的限制， 其可以螺合方式螺合， 亦或以一体成型制成； 该中空轴 杆 20并轴设至少一轴承 50于该等轴套 22、 23间， 使该轴承 50设于该容置槽 112内， 缘 113卡置固定该轴承 50， 使该轴承 50不致于产生脱落。 该弹簧件 30为一长条状的压缩弹簧， 其于前端套设于该延伸轴杆 25上， 藉该 延伸轴杆 25上的螺纹段 251以增加两者的紧密度， 不致使该弹簧件 30容易脱落。
该隔离件 40为一矩形板体， 供装设于该电钻的电钻夹头 62 (如图 4所示)前端， 其于上方设有一圆孔 41， 且该隔离件 40内侧延伸设有一中空杆 42， 该中空杆 42上 方设有至少一螺纹段 421， 该中空杆 42供弹簧件 30相对该延伸轴杆 25的另一端套 设， 该螺纹段 421的功用与该延伸轴杆 25的螺纹段 251相同； 该圆孔 41供该钻头 61 穿设，并使其贯穿于上述的各部件，且该等弹性垫片 24上的切割痕 241可弹性开启， 以紧密地夹持该钻头 61， 藉此， 可使该弹性垫片 24夹持各种不同规格的钻头 61 ; 藉该隔离件 40以隔离弹簧件 30与电钻夹头 62， 避免两者直接接触而产生卷入卡死， 而无法运作的情形， 此外， 藉由二弹性垫片 24的设计， 除可增加防尘效果外， 并 具有平衡钻头 61与中空壳体 10的功用， 避免因失衡而造成中空壳体 10产生晃动而 影响集尘效果。
明了上述结构后， 以下针对本发明的动作及原理作一详细说明：
如图 4及图 5所示， 当欲进行一墙面 70的水平钻孔时， 将该盖体 12紧贴于墙面 70， 透过透视该中空壳体 10以将钻头 61对准欲钻孔处， 藉电钻机 60的运作， 该弹 簧件 30会产生压缩的力量， 而该盖体 12仍静止不动， 使得产生的尘屑 71可经由开 孔 122并沿锥形部 121的锥度落入集中于该中空壳体 10内， 以达到集尘的效果， 并 确保尘屑 71不会产生外漏的情形。
如图 6所示， 当欲进行一天花板 80的垂直钻孔时， 使用方式亦如上所述， 产生 的尘屑 81可直接经由开孔 122垂直落入于该中空壳体 10内； 藉由该轴承 50的设置， 使得该钻头 61于转动时， 并不会带动该中空壳体 10产生同步转动， 仅会使其他部 件随之转动， 因此并不会造成中空壳体 10内的尘屑 71、 81产生四溅而造成清理上 不便， 且亦可避免长期使用下， 该中空壳体 10因转动而与墙面 70或天花板 80产生 摩擦， 而造成中空壳体 10损坏， 或墙面 70、 天花板 80磨损的情形。
于完成钻孔后， 清理该中空壳体 10内的尘屑 71、 81时， 可直接将本发明自钻 头 61上拆卸下， 以使尘屑 71、 81自开孔 122倒出， 或将该盖体 12开启， 以倒出该盖 体 12及该座体 11内的尘屑 71、 81， 亦或直接连同电钻机 60朝下倒出， 此时， 藉由 该等弹性垫片 24上的切割痕 241紧密地夹持钻头 61， 使尘屑 71、 81不致于外漏， 并 可利用其夹持钻头 61时所产生的抓力， 使得尘屑 71、 81倒出时， 并不会使本发明 产生向下滑落的情形； 而利用该隔离件 40的矩形设计， 避免本发明于单独横置时 容易产生滚动。
由上述所言， 本发明于进行各部件装卸作业时， 无需使用任何工具， 因此具 有装卸快速、 方便的优点； 且透过该中空壳体 10的形状设计， 以缩小其体积， 以 便利性， 而其透明设计， 除可便于对准欲钻孔处外， 亦可藉此直接 观察内部的尘屑 71、 81是否达到一定的量， 而便于清洁作业的进行； 此外， 由于 本发明可适用于各种尺寸规格、 厂牌的电钻机 60及钻头 61， 因此可提高使用上的 效益， 且对于制造商而言， 无需为配合不同电钻机 60或钻头 61而制造出不同规格， 因此可大幅地降低制造成本。
虽本发明是以一个最佳实施例作说明， 但精于此技艺者能在不脱离本发明精 神与范畴下作各种不同形式的改变。 以上所举实施例仅用以说明本发明而已， 非 用以限制本发明的范围。 举凡不违本发明精神所从事的种种修改或变化， 倶属本 发明申请专利范围。
