Description

一种冰箱翻转梁装置及对开门冰箱
技术领域
本实用新型涉及电器设备的技术领域，特别涉及一种冰箱翻转梁装置以及装配有该冰箱翻转梁装置的对开门冰箱 。
背景技术
已知的法式对开门冰箱，冷藏室有两个箱门，左右两个箱门关门后有缝隙，为了密封此缝隙，需要设计一种翻转梁结构，在箱门关闭时，翻转梁与箱门正平面平行，密封箱门间隙，安装翻转梁的的左箱门或右箱门打开时，翻转梁旋转，翻转后与箱门侧面平行，与正面垂直，否则，箱门再次关闭时，翻转梁会与另一箱门干涉，导致箱门不能关闭。
传统翻转梁是靠一个扭转弹簧通过翻转梁的运动改变扭转弹簧的弹性状态，从而实现扭转弹簧对翻转梁力度改变，以通过扭转弹簧的弹力使翻转梁保持展开和闭合（翻转梁的翻转或展开）的状态，其结构比较简单，但是扭转弹簧依靠上下两个转轴支撑，在使用过程中，扭转弹簧扭曲大，容易变形，可靠性低。
中国专利申请CN102425908A公开一种用于冰箱的翻转梁。其翻转梁包括：翻转梁本体、第一装置和第二装置，其中第一装置和第二装置提出了使用两个压缩弹簧和两个设有配套的螺旋斜面的转轴，实现翻转梁的翻转。
这种方式的翻转梁设计，结构复杂，不易装配，且两个压缩弹簧裸露在产品可见处，影响翻转结构的 美观性，因而在批量的产品中没有得到应用。
实用新型内容
本实用新型要解决的问题是针对现有技术的不足而提供一种结构简单、易于装配的冰箱 翻转梁装置。
本实用新型还提供一种装配有该冰箱 翻转梁装置的对开门冰箱。
为解决上述技术问题，本实用新型技术方案为：
本实用新型第一方面提供一种冰箱 翻转梁装置，其包括安装在冰箱门体上的支座、滑动块、压缩弹簧、翻转梁主体和安装盖，所述支座的一端设有铰链轴，所述滑动块为中间设有同心圆柱通孔的圆柱体，滑动块与支座的接触面相互设有匹配的凸轮结构，滑动块与翻转梁主体设有相互配合的轴向导向结构，所述翻转梁主体设有容纳滑动块的圆柱体空间，所述压缩弹簧、滑动块依次安装到支座的铰链轴上，再装配到翻转梁主体的圆柱体空间，安装盖位于支座相对于其铰链轴的另一端并装配到翻转梁主体上。翻转梁主体通过其轴心旋转使滑动块沿轴向上下滑动。翻转梁主体翻转时，滑动块沿轴向上下滑动，压缩弹簧产生弹力，安装盖支撑在支座与旋转梁主体之间，使压缩弹簧压缩时，支座不能沿轴向滑动。
优选的方案是，所述滑动块的轴向导向结构为设于外圆柱面的至少两个平行于轴向的导向台或导向槽，所述翻转梁主体的轴向导向结构与滑动块配对的导向槽或导向台。
进一步的优选的方案是，所述滑动块的凸轮结构为设于圆柱体端面、等分为若干份的凹凸结构，所述支座的凸轮结构为相应等份的凹凸结构，其设于固定铰链轴的圆柱端面上。最佳的是，所述滑动块与支座的相匹配的凸轮结构都是圆柱4等分凹凸结构。
进一步的优选的方案是，所述安装盖设有卡勾，通过卡勾装配到翻转梁主体上。装配简便，装配完的安装盖支撑在支座与翻转梁主体上，使翻转梁翻转时，支座不能沿轴向滑动。
本实用新型第二方面提供一种对开门冰箱，其包括冷藏箱体，冷藏箱体有左、右两个箱门，所述左箱门或右箱门装配有上述冰箱翻转梁装置，所述翻转梁主体设有翻转导向结构，所述冷藏室箱体上部或下部中间处设有与翻转导向结构配对的导向结构。该冰箱翻转梁装置能精确实现90度的翻转。

与现有技术相比，本实用新型具有如下有益效果：
本实用新型冰箱翻转梁装置结构简单、易于装配，该翻转梁装置在翻转过程中，通过两相互配合的凸轮结构，在压缩弹簧的作用下，实现翻转梁在外力辅助下由0度翻转45度后，自动由45度翻转至90度；同时在外力辅助下反向从90度翻转至45度后，自动由45度翻转至0度初始状态，完成翻转梁的展开和闭合。本实用新型冰箱翻转梁装置实现精确90度翻转，而且装配完毕压缩弹簧和滑动块隐藏于不可见处，保证外观简洁。本 实用新型实用性强，应用广泛。

具体实施方式
以下结合实施例及附图对本实用新型进行详细的描述。
图1公开一种冰箱 翻转梁装置，包括安装在冰箱门体上的支座4、滑动块3、压缩弹簧2、翻转梁主体1和安装盖5，其中支座4的一端设有铰链轴42，滑动块3为中间设有同心圆柱通孔的圆柱体，滑动块3与支座4的接触面设有相互匹配的凸轮结构，安装盖5上设有卡勾，通过卡勾装配到翻转梁主体1上。如图2所示，分别为第一凸轮结构31和第二凸轮结构41。而滑动块3与翻转梁主体1设有相互配合的轴向导向结构，如图3所示，翻转梁主体1的轴向导向结构为导向槽11，滑动块3的轴向导向结构为与导向槽11配合的导向台32，另外，翻转梁主体1设有容纳滑动块3的圆柱体空间。
装配时，压缩弹簧2、滑动块3依次安装到支座4的铰链轴上，再装配到翻转梁主体1的圆柱体空间，安装盖5位于支座4相对于其铰链轴的另一端并装配到翻转梁主体1上。即是压缩弹簧2一端面与旋转梁主体1贴合，另一端面与滑动块3平面贴合，翻转梁主体1通过其轴心旋转使滑动块3沿轴向上下滑动。翻转梁主体1翻转时，滑动块3沿轴向上下滑动，压缩弹簧2产生弹力，安装盖5支撑在支座4与旋转梁主体1之间，使压缩弹簧2压缩时，支座4不能沿轴向滑动。
如图3，滑动块3的轴向导向结构为设于外圆柱面的至少两个平行于轴向的导向台或导向槽，翻转梁主体1的轴向导向结构与滑动块3配对。
如图2， 滑动块3的凸轮结构，即为第一凸轮结构31设于滑动块3的圆柱体端面，为4等分的凹凸结构；支座4的凸轮结构，即为第二凸轮结构41，也相应为4等分的凹凸结构。
图4，为冰箱翻转梁装置在最初始状态，滑动块3与支座4的凸轮结构在两凸轮啮合的最低点位置配装，冰箱翻转梁装置在翻转过程中，即翻转梁主体1以支座4的轴心线为轴旋转的过程中，滑动块3在支座4的凸轮结构作用下，沿轴线方向向上滑动，压缩弹簧2同时被压缩，当翻转梁主体1旋转45度时，滑动块3向上滑动到两凸轮啮合最高点（见图5），此时压缩弹簧2被压缩到最小长度，弹力到达最大值，翻转梁主体4继续旋转时，滑动块2在压缩弹簧3压力作用下，越过支座4凸轮啮合最高点，自动向下滑动，完成45度至90的的旋转，直至与支座4在凸轮啮合最低点配合。图6所示。
在冰箱翻转梁装置完成这一次翻转过程中，由0度至45时，通过外力辅助完成；45度至90度时，通过压缩弹簧2的弹力，由翻转梁主体1自动完成。同时在这一次翻转过程中翻转梁主体1和滑动块3相对于支座4旋转90度，滑动块3相对于翻转梁主体1上下滑动一个周期，最终停在初始位置，滑动块3相对于支座4旋转90度。冰箱翻转梁装置反向回转过程与上述过程动作相反，从而完成了翻转梁的展开和闭合。
如图7、图8，本实用新型还提供 一种对开门冰箱，其包括冷藏箱体7，冷藏箱体7有左、右两个箱门，左箱门或右箱门装配有上述冰箱翻转梁装置，翻转梁主体1设有翻转导向结构12，冷藏室箱体7上部或下部中间处设有与翻转导向结构12配对的导向结构71。该冰箱翻转梁装置能精确实现90度的翻转。图7，左箱门6上装配有箱体冰箱翻转梁装置，冷藏室箱体7上设有与翻转梁主体1的翻转导向结构12配对的导向结构71。
另外，左箱门或右箱门预埋有安装座（图中未示），图2中，支座4设有固定在安装座上的燕尾槽结构43。设置燕尾槽结构43，便于支座4的安装。
以上实施例仅用于说明本实用新型的技术方案，而非对其限制；尽管参照较佳实施例对本实用新型进行了详细的说明，所属领域的普通技术人员应当理解，依然可以对本实用新型的具体实施方式进行修改或者对部分技术特征进行等同替换，而不脱离本实用新型技术方案的精神，其均应涵盖在本实用新型请求保护的技术方案范围当中。
