一种简易门镜
本技术涉及一种配件,尤其适应人们用于各种防盗门上的简易门镜。
技术介绍
随着社会的发展,经济的繁荣,生活水平的提高,人们家里的各种贵重物品也越来越多,因此各种款式的防盗门深受人们的青睐,门镜是防盗门上不可缺少的配件,但以前防盗门上的门镜存在着一些问题,就是小偷或不法分子在门外容易把防盗门上的门镜旋转卸下,用铁丝伸进门镜圆孔内打开,然后入室行窃,本人经过研发,先后申请了专利号为201620398897.2、201621117030.1和201621117038.8等专利,虽然每个专利都各有不同的特点,但是结构复杂,制造麻烦。
技术实现思路
为了克服上述问题的不足,本技术提供一种简易门镜,该简易门镜为了使门镜防反旋结构合理科学,就是要使外管和内管只能往一个方向旋转,不能反旋,在外管上设有长槽,在内管的上端设有单向齿,在内管的单向齿与外管的长槽之间设有一个单向圈,单向圈上设有单向齿,单向圈上单向齿的齿数与内管上单向齿的齿数相等结构相反,两齿相对结为一体,就能达到防反旋的目的,为了方便旋转,在单向齿的一边设有斜边,在单向圈上设有压簧,压簧的一头设有卡圈,在旋转的作用下,内管的单向齿斜面推动单向圈往后运动,使压簧缩短旋转过一齿,在压簧的作用下单向圈向前运动,两单向齿相互咬合压簧伸长,达到旋旋的目的,反旋是直边与直边的旋转,不能使单向圈往上运动脱离单向齿相互咬合,使其达到不能反旋的目的。具有结构简单,制造省力,牢固耐用的特点。本技术解决其技术问题所采用的技术方案是:一种简易门镜,包括前夹板、后夹板、外管和内管,在前夹板上设有透镜和内管,在后夹板上设有外管和软 ...
