具体实施方式
以下将结合附图所示的具体实施方式对本发明进行详细描述。但这些实施方式并不限制本发明，本领域的普通技术人员根据这些实施方式所做出的结构、方法、或功能上的变换均包含在本发明的保护范围内。
如图1至图6所示，可更换门面的冰箱门100包括发泡门体20和可拆卸连接发泡门体20的门饰板10；其中，门饰板10的后侧设置 配合件40；发泡门体10的前侧设置磁性锁扣30，磁性锁扣30包括多个滚珠321；门饰板10装配于发泡门体20的前侧时，配合件40插入磁性锁扣30中，且多个滚珠321夹持配合件40限制门饰板10在前后方向上的位移。
如图4所示，配合件40为设置于门饰板10后侧的挂针，其通过连接板41锁附于门饰板10的后侧，挂针的前端包括凹部42，凹部42环绕挂针的外表面设置。
如图2、图5和图6中所示，磁性锁扣30包括壳体和保持架32，保持架32装配于壳体内部，保持架32包括轴向通孔323和多个径向通孔322，多个径向通孔322分别与轴向通孔323相互连通。其中，多个滚珠321分别容置于多个径向通孔322中。
多个滚珠321在上下方向上的位移被壳体内部的侧壁限制，使得挂针插入磁性锁扣30的保持架32的轴向通孔323中时，多个滚珠321卡入挂针前端的凹部43中，挂针与磁性锁扣30相互锁定。
本实施例中，当滚珠321容置于径向通孔322中时，滚珠321外侧部分凸出于保持架32的外壁，且滚珠321内侧部分凸出于保持架32的内壁，其中，保持架32的内壁为轴向通孔323的孔壁。即，滚珠321容置于径向通孔322中，且滚珠321分别凸出保持架32的外壁和轴向通孔323的孔壁。
进一步，磁性锁扣30的壳体包括相对设置的前盖31和后盖35，前盖31包括一体成型的前面板311和容置部312，容置部312位于前面板311的后侧且朝向后盖35延伸；对应于容置部312，后盖35设 置装配腔351；当前盖31装配于后盖35前侧时，容置部312插入装配腔351中，容置部312的后端靠近装配腔351的后壁。
前面板311上具有贯孔313；容置部312具有容置腔314；其中，贯孔313与容置腔314相互连通。本实施例中，容置腔314为通孔结构。
如图5和图6所示，磁性锁扣30还包括磁环34和弹性件33，磁环34和弹性件33分别设置于保持架32的两侧，其中，磁环34、保持架32以及弹性件33分别容置于前盖31的容置部312中容置腔314中；磁环34靠近前面板311，弹性件33的后端抵靠于装配腔351后壁上的凹槽352中。
另外，保持架32的后端凸出延伸部324，弹性件33的前端套设在延伸部324上，且弹性抵靠保持架32的后端。
本实施例中，多个滚珠321预先装配于保持架32中的径向通孔322中；再将磁环34、保持架32以及弹性件33依次装配于前盖31的容置部312的容置腔314中；接着，将前盖31的容置部312插入后盖35的装配腔351中，此时，弹性件33的后端限位于装配腔351的后壁的凹槽352中。
如图6中所示，容置腔314包括第一区段3141、第二区段3142以及连接第一区段3141和第二区段3142的第三区段3143，其中，第一区段3141的内径小于第二区段3142的内径。
本实施例中，第三区段3143为大致为锥形结构，锥形结构的前端与第一区段3141的后端连接，锥形结构的后端与第二区段3142的 前端连接。其中，锥形结构的前端的内径大致等于第一区段3141的内径，锥形结构的后端的内径大致等于第二区段3142的内径。
需要说明的是，将容置腔314区分为第一区段3141、第二区段3142和第三区段3143其目的是在于更好的说明容置腔的314的内部结构，在实际产品中，可视作两个不同内径的中空柱体构成了容置腔314，且内径较大的中空柱体的前端大致为弧形。
继续参照图6，磁环34容置于第一区段3141中，保持架32的前端容置于第一区段3141中，保持架32上的滚珠321以及保持架32的后端分别容置于第三区段3143和第二区段3142中。其中，多个滚珠321在上下方向的位移分别被第三区段3143限制，且由于第一区段3141的内径最小，挂针在装配及拆卸的过程中，多个滚珠321不会越过第三区段3143且朝向第一区段3141中移动。
以下将结合图7至图11说明门饰板10和发泡门体20的装配与拆卸过程。
如图7至图9所示，将门饰板10朝向发泡门体20的前侧移动，门饰板10后侧的挂针(配合件40)插入发泡门体20的上饰条21前侧的磁性锁扣30中。
具体来讲，挂针依次穿过前面板311上贯孔312，进入磁环34的孔部341以及保持架32的轴向通孔323中，保持架32的多个径向通孔322中多个滚珠321分别卡入挂针前端的凹部43中，进而挂针被多个滚珠321夹持，挂针被磁性锁扣锁定，此时，门饰板10装配于发泡门体20的前侧。藉由多个滚珠321卡入挂针的凹部43中，门饰 板10在前后方向上的位移被限制。
如图10至图11所示，当需要将门饰板10从发泡门体20的前侧拆卸下来时，另外提供解锁磁扣50，其中解锁磁扣50的磁性与磁环34的磁性相同，将解锁磁扣50贴近门饰板10的前侧并，解锁磁扣50的位置与发泡门体20前侧的磁性锁扣30内磁环34相对应，利用磁性相同，相互排斥的原理，磁环34在容置腔314中向后移动，推抵保持架32，保持架32挤压弹性件33向后移动，并带动多个滚珠321一并向后移动，多个滚珠321从挂针前端的凹部43中移出，磁性锁扣30与挂针解除锁定，门饰板10在前后方向上的位移限制被移除。
另外，通过移除门饰板10和发泡门体20在上下方向、左右方向上可拆卸结构，挂针可从磁性锁扣30中拔出门饰板10可从发泡门体20的前侧被拆卸。
此外，解锁磁扣50被移除，藉由弹性件33的弹性力，其推动保持架32和磁环34一并在容置腔314中向前移动，磁环34和保持架32复位。
本实施例中，为了便于用户准确的将解锁磁扣50放置在门饰板10对应于磁性锁扣30的位置上，门饰板10的前侧可设置标记图案(未图示)，标记图案的位置对应于发泡门体20前侧的磁性锁扣30的位置。
其中，解锁磁扣50作为一个独立的配件，其在不使用时，可吸附于冰箱的金属箱体的侧壁上，防止丢失。
综上，本发明提供一种可更换门面的冰箱门，通过发泡门体中的 磁性锁扣的多个滚珠夹持门饰板后侧的配合件，限制门饰板10在前后方向上的位移。另外，通过提供同极性的解锁磁扣与磁性锁扣中的磁环相互排斥，使得多个滚珠解除与配合件的锁定关系，进而实现快速拆卸和安装门饰板的效果。
应当理解，虽然本说明书按照实施方式加以描述，但并非每个实施方式仅包含一个独立的技术方案，说明书的这种叙述方式仅仅是为清楚起见，本领域技术人员应当将说明书作为一个整体，各实施方式中的技术方案也可以经适当组合，形成本领域技术人员可以理解的其他实施方式。
上文所列出的一系列的详细说明仅仅是针对本发明的可行性实施方式的具体说明，它们并非用以限制本发明的保护范围，凡未脱离本发明技艺精神所作的等效实施方式或变更均应包含在本发明的保护范围之内。
