                        高压锅不松动手把的研究与设计

                        2013/5/11 9:46:55
                        1 引言

                                高压锅是现代家庭的必备炊具之一。由于高压锅具有独特的高温高压功能,从而大大缩短了时间,同时节约了能源[1]。用户在使用高压锅的过程中,通过上手把和下手把的配合使用实现锅体的旋转开合。在绝大多数家用高压锅中,锅体与下手把之间均通过如图1 所示的连接块连接。

                                 在使用过程中,螺钉正压力的大小直接影响锅体自身重量及锅体倾斜( 将要倒出锅内物体) 时传递的扭矩,甚至会致使螺钉外螺纹与连接块上的内螺纹之间产生松动。如果此时正压力产生的摩擦力矩大于倒出锅内物体所需的扭矩,则手把处于不松动状态;如果正力产生的摩擦力矩小于倒出锅内物体所需的扭矩,则手把会松动。手把松动后,若没有用工具及时将螺钉拧紧,就会导致螺纹间长期松动而使螺纹失效。下手把甚至会沿螺纹中心旋转,给使用者带来很大不便。高压锅手把结构的缺陷而导致手把松动,使得高压锅除了存在内压高的安全隐患外,还存在下手把脱离连接块、锅体倾翻烫伤用户的安全隐患。综上所述,传统高压锅手把结构存在以下不足。
                         

                                 ( 1) 下手把与连接块之间仅靠旋紧螺钉产生的力来得到固定。其连接块上内螺纹与螺钉外螺纹由于温度变化,材料热膨胀系数不同而产生间隙,从而引起松动。
