一种高压烤箱的新型门结构，包括烤箱主体和烤箱门框，所述烤箱主体和烤箱门框之间设有锁紧装置，所述锁紧装置包括安装在烤箱主体上的挂钩、引导挂钩钩紧烤箱门框的导向机构、带动挂钩移动的手柄，所述烤箱门框上可被挂钩挂住的锁紧孔，所述挂钩设置在一可移动的活动架上，所述手柄铰接在烤箱主体上，手柄上铰接有连杆，所述连杆的另一端铰接在活动架上。
在本实用新型中，所述挂钩设有两个，分别位于活动架的上下方。
在本实用新型中，所述导向机构包括设置活动架上的滑槽和设置在烤箱主体上的导向柱，所述导向柱穿过滑槽并在滑槽内滑动。
在本实用新型中，所述滑槽为“L”字形。
在本实用新型中，所述烤箱主体上还设有预锁装置，所述预锁装置包括设置在烤箱门框上可伸入烤箱主体内的活动钩和设置在烤箱主体内可被活动钩挂住的卡槽。
在本实用新型中，所述活动钩分别设有两个，并安装在一联动架上。
在本实用新型中，所述烤箱门框上设有可打开预锁装置的门开关，所述门开关包括 活动推杆、连接在活动推杆上的按钮、连接在活动推杆上的复位弹簧Ⅰ，所述活动推杆的前端与联动架连接，所述联动架上连接有复位弹簧Ⅱ。
本实用新型的有益效果是：本实用新型将锁紧连接件设置在烤箱主体内，并从烤箱主体内伸出并钩在烤箱门框上，转动手柄后，将烤箱门框锁紧，锁紧强度高，密封效果更好；进一步，本实用新型通过两条联动杆件完成了锁紧动作，结构简单、合理、强度高。
