Description

一种用于烤盘的自动升降脚机构 技术领域
本发明涉及一种煎烤器的烤盘领域，特别是指一种用于烤盘的自动升降脚机构。
背景技术
现有技术中的煎烤器种类繁多，但是现有技术中的煎烤器特别是单烤盘类煎烤器通常不具有烤盘面的角度调节功能，这就存在如下问题：一是只能实现单一烹饪，因为不同的烹饪方式、烹饪不同的食材对泄油等的要求均不同；二是不能满足人们烹饪习惯差异化的要求，因为不同的人的烹饪习惯不同，对烤盘的角度要求自然不同，这种烤盘因烹调角度不能调节，自然会降低在市场上的竞争力。
发明内容
本发明的主要目的在于克服现有技术中的单烤盘类煎烤器其烤盘角度无法调节的缺点，提供一种用于烤盘的自动升降脚机构。
本发明采用如下技术方案：
一种用于烤盘的自动升降脚机构，它包括
一腔体，该腔体内壁上设有至少一第一凸柱和至少一第二凸柱，该第一凸柱和该第二凸柱相临近，并且该第一凸柱和该第二凸柱的上端分别形成一倾斜的第一导向面和一倾斜的第二导向面，且该第一导向面和该第二导向面的倾斜方向相同，并在该第一导向面的最低端与该第二导向面的最高端之间形成一止动槽；该第二导向面的最低端旁形成一上下方向的第二滑道，该第二滑道的末端封闭形成一挡墙；
一伸缩杆，该伸缩杆具有一头部和一按压部，该头部外周凸出设有限位于所述第二滑道内并沿该第二滑道上下滑动的第二滑动筋条；
一旋转杆，该旋转杆抵靠于所述伸缩杆的头部，该旋转杆外周设有至少一限位筋条，该限位筋条的底端在所述止动槽和所述第二滑道之间运动；
一弹簧，抵靠在所述旋转杆的顶端。
根据本发明的一较佳实施方式，所述腔体的上、下两端均开口，该上端开口藉由一盖体封闭，所述弹簧抵靠于该盖体和所述旋转杆的顶端之间；所述伸缩杆的按压部伸出该下端开口。
根据本发明的一较佳实施方式，在所述第一凸柱上、所述止动槽的下方开设有一上下方向的第一滑道，所述伸缩杆的头部外周凸出设有限位于该第一滑道内并沿该第一滑道上下滑动的第一滑动筋条；该第一滑道的深度小于所述第二滑道。
根据本发明的一较佳实施方式，所述第一滑动筋条和所述第二滑动筋条的上端分別向上凸起形成第一接触面和第二接觸面，所述限位筋条的底端形成一倾斜接触面，该倾斜接触面在该第一滑动筋条的第一接触面和该第二滑动筋条的第二接触面之间往复运动；该倾斜接触面的倾斜方向与所述第一导向面和所述第二导向面的倾斜方向相同。
本发明的一种用于烤盘的自动升降脚机构在使用时，分别装设于烤盘一侧的两端，通过调节其升降实现调节烤盘角度的目的。
当本发明的一种用于烤盘的自动升降脚机构处于伸长状态时，此时限位筋条位于第二滑道内，限位筋条底端的倾斜接触面抵靠在第二滑动筋条上端的第二接触面上，其缩短动作如下：按压伸缩杆的按压部，弹簧被压缩，第二滑动筋条与限位筋条同时沿着第二滑道向上滑动，当限位筋条底端的倾斜接触面越过第一导向面的最高点时，第二滑动筋条上端的第二接触面将挤压限位筋条底端的倾斜接触面滑入第一导向面，此时在弹簧压力的作用下旋转杆旋转并且向下滑动使限位筋条底端的倾斜接触面卡入止动槽上，并且此时限位筋条底端的倾斜接触面抵靠在第一滑动筋条上端的第一接触面上，完成缩短动作。
当本发明的一种用于烤盘的自动升降脚机构处于缩短状态时，此时限位筋条底端的倾斜接触面卡入止动槽上，并且限位筋条底端的倾斜接触面抵靠在第一滑动筋条上端的第一接触面上，其伸长动作如下：按压伸缩杆的按压部，克服弹簧的作用力，使第一滑动筋条上端的第一接触面压迫限位筋条底端的倾斜接触面使其向上运动脱离止动槽以越过第二导向面的最高点，并使限位筋条底端的倾斜接触面滑入第二导向面，此时在弹簧压力的作用下旋转杆旋转并且向下滑动使限位筋条底端的倾斜接触面滑入第二滑道，并使限位筋条底端的倾斜接触面抵靠在第二滑动筋条上端的第二接触面，在弹簧压力的作用下，旋转杆与伸缩杆同时沿着第二滑道向下运动，当第二滑动筋条的下端抵靠在第二滑道末端的挡墙上时，旋转杆与伸缩杆停止运动，完成伸长动作。
由上述对本发明的描述可知，与现有技术相比，本发明的一种用于烤盘的自动升降脚机构藉由腔体、伸缩杆、旋转杆和弹簧的配合轻松实现伸长和缩短运动，实现烤盘的角度可调，从而使得烤盘可具有多种烹饪方式，也使得烤盘具有泄油功能，且以较少的成本实现烤盘多元化的销售卖点，增加其市场竞争力。
