Abstract

The utility model relates to a piezoelectric ceramic assembly with safety lock set. The safety lock set is made up of a flexible lock pin and a code dialing disc component. The lock pin is arranged on a piezoelectric ceramic inner sleeve or a piezoelectric ceramic outer sleeve. The code dialing disc component comprises a disc shaft and at least one dialing disc. The disc shaft is vertical to the inner sleeve or the outer sleeve, and the dialing disc is sleeved rotatably on the disc shaft. The dialing disc is provided with a sliding slot which forms cam type cooperation with head surface of the lock pin. The sliding slot is made up of a downward pressing slide slot and a return slide slot. Inlet of the downward pressing slide slot is arranged in malposition with outlet of the return slide slot. Tail of the downward pressing slide slot contacts starting return end of the return slide slot, and the junction is provided with a return stop element which can prevent return of the lock pin along the downward pressing slide slot. An entry stop element which can prevent the downward pressing slide slot contacting piezoelectric working point is arranged in the return slide slot or exit of the return slide slot. Electric lighter or electric igniter adopting the utility model can prevent misapplication of child.
本实用新型涉及一种带有保险锁装置的压电陶瓷总成,保险锁装置由具有弹性的锁栓和拨码盘组件组成,锁栓设置在压电陶瓷内套或压电陶瓷外套上,拨码盘组件由拨盘轴和至少一个拨盘构成,拨盘轴与外套或内套相垂直,拨盘套装在拨盘轴上并可绕拨盘轴转动,拨盘上设置有与锁栓呈端面槽凸轮式配合的锁栓滑槽,锁栓滑槽由下压锁栓滑槽和复位锁栓滑槽两部分组成,下压锁栓滑槽入口和复位锁栓滑槽出口错位设置,下压锁栓滑槽的末端和复位锁栓滑槽的开始复位端相交,其相交处设有防止锁栓沿下压锁栓滑槽返回的止回机构,复位锁栓滑槽中或其出口处设有可防止锁栓下压至压电工作点的止入机构。采用本实用新型的电子打火机和电子点火器,可有效防止儿童误用。
