A dust-proof cover for impact drill consists of a retractable cystic bellows and a spring bracket with a metal compression ring. The front end of the cystic bellows has a sealing cushion made of one body, and the back end has a fixed sleeve which can be connected with the impact drill. The cystic bellows and sealing rubber pads are made of advanced silicone rubber. The metal compression rings are welded together with the spring bracket and the back end is made. A spring connecting nose and a spring connecting nose are connected by a spring bracket connecting hole. The front end sealing rubber pad of the retractable cystic bellows is inserted into the metal pressing ring. The back end bellows fixing sleeve is fixed at the front end of the impact drill and fastened with clips. A spring bracket fixing seat is made on the clip. The spring connecting nose is inserted into the spring bracket fixing seat and fixed with a connecting pin because of gold. Under the elastic force of the spring support, the ring is always pressed tightly to seal the rubber cushion. The sand and dust drilled by the alloy Turner enters the cystic bellows, which effectively prevents the dispersion of sand and dust and protects the environment clean.
【技术实现步骤摘要】
一种冲击电钻防尘罩
本专利涉及环保建筑、电器、设备安装作业
,尤其是涉及一种冲击电钻防尘罩。
技术介绍
目前家用电器、空调等设备在室内外安装时,需要在砖墙、水泥墙打固定孔;冲击电钻打起孔来尘土飞扬、污染环境,飞扬的砂石灰尘、尤其装修好的室内,打扫清洁起来十分困难。
技术实现思路
本专利的目的是针对目前建筑、室内外砖墙、水泥墙冲击电钻打孔的现状,而提供的一种冲击电钻防尘罩。本专利解决其技术问题所采用的技术方案是;由可伸缩的囊状波纹管、和带有金属压紧环的弹簧支架所组成,其中囊状波纹管前端有一体制作的密封胶垫、后端制作有可与冲击电钻连接的波纹管固定套,囊状波纹管和密封胶垫采用高级硅橡胶制作,还由于金属压紧环与弹簧支架焊接在一起、后端制作有弹簧连接鼻、弹簧连接鼻上面有弹簧支架连接孔,将可伸缩的囊状波纹管的前端密封胶垫、套入金属压紧环中,后端波纹管固定套套在冲击电钻前端、用卡子紧固,卡子上面制作有弹簧支架固定座,将弹簧连接鼻插入弹簧支架固定座中、插入连接销固定。本专利工作时;将需要的合金转头、装入冲击电钻的钻卡头中、卡紧合金转头,安装本专利技术;对准欲打孔的位置、密封胶垫压紧钻孔位置,启动冲击电钻、钻孔开始;由于金属压紧环在弹簧支架的弹力下、始终压紧密封胶垫,合金转头钻掉的砂石、粉尘进入囊状波纹管内,达到所需深度、之后囊状波纹管的钻头孔向下,用一容器接住、用手反复压缩囊状波纹管,使内部砂石、粉尘排尽,之后进行下一个工作,由于囊状波纹管的密封作用、有效防止了砂石、粉尘的飞散,保护了环境的洁净。本专利的有益效果在于:将钻孔位置与钻头进行封闭、将钻削下来的砂石粉尘、落入 ...
