Hammer is a kind of electric drill, mainly used for drilling in concrete, brick, stone and so on. Dust falling by workers when they drill into the top will damage the health and health of the operator. The utility model relates to an electric dust cover, composed of the outer cover and the inner cover, and a telescopic tube, which is characterized in that the cover is a hollow square body, the bottom surface has four claw movable, easy to hammer on the handling; for the cover of the barrel, the bottom bulge, the center has a cover hole, hole cover drill root is slightly larger; the telescopic tube for threaded or corrugated pipe, the pipe stress is scalable, but does not automatically rebound. The inner cover is clamped in the outer cover and is fixed by screws; the inner cover is clamped at the lower opening of the telescopic pipe and is fixed with screws. The inner cover and the telescopic tube are also made of a whole. To the top of the dust cover before drilling, set in the hammer head, the telescopic tube opened, when drilling dust falls in the hood. The utility model will bring the gospel of the hammer thousands on thousands of users.
【技术实现步骤摘要】
电锤是电钻中的一个分类,主要用来在混凝土、砖墙、石材等上面钻孔。本技术涉 及一种电锤辅助设备,确切的说是一种与电锤配套使用的防尘罩。
技术介绍
电锤是建筑和装饰工程中常用的工具。工人用其向顶部钻孔时,如果没有防尘装置回会 使钻下的灰尘四处飞扬,从而不仅有碍操作,而且有损操作者的卫生与健康。1932年,德 国博世公司推出世界第一台电锤,然而自电锤问世以来,市场上一直未出现一种经济实用的 电锤防尘装置。博世公司有一种可连接家用吸尘器和电锤的吸尘装置(资料来自博世电锤说 明书),效果应该不错,但在发展中国家大多没有使用条件;在发达国家吸尘器虽普及,但在 经济实用携带方便方面又有所欠缺。目前中国市场上常见的电锤防尘罩为倒置瓶盖状,用黑 色橡胶制成,其虽然便宜,但防尘效果太差。
技术实现思路
本技术的目的是给人们提供一种效果显著,操作简单,携带方便,价格低廉的电锤防尘罩,其由外罩、内罩和伸縮管组成,特征在于外罩为空心四方体,其四个棱边为斜坡面,斜坡面仅上部一小截和主体相连,其余部分均为空隙;外罩底部是四个有空洞的卡爪,分 别和外罩的四个主面相连;内罩为桶状,底部向上凸起,中心有一罩孔,孔径比钻头根部略 大;伸縮管为螺纹状或波纹状,该管受力可伸縮,但不会自动反弹,其特性和家用的抽油烟 机排烟管相同。内罩卡在外罩内,用螺丝固定,内罩上口卡在伸縮管下口内,也用螺丝固定。 内罩和伸縮管也可是整体制成。用电锤向顶部钻孔前,先插钻头,将防尘罩于中心罩孔处从钻头上端套下,再把手指插 在外罩棱边空隙处,将外罩底部四个卡爪撑开即可套在电锤头部。如果钻头比罩孔粗,可先 套好罩再插钻头。将 ...
