Description

用于洗衣机包装的防护部件及具有其的洗衣机包装装置 技术领域
本发明属于洗衣机包装防护技术领域，尤其是涉及一种用于洗衣机包装的防护部件及具有其的洗衣机包装装置。
背景技术
随着人们生活质量的提高，越来越多的家庭开始使用洗衣机。人们对洗衣机的外观和使用性能提出了更高的要求。洗衣机作为一种大型家用电器，尤其是滚筒洗衣机，若包装不够完善，在运输过程中极易发生损坏。
滚筒洗衣机是模仿棒锤击打衣物原理，将洗涤剂、洗涤水、洗涤物置于滚筒内，通过电机驱动滚筒旋转而进行洗涤的装置。现有滚筒洗衣机包括外壳、门、外筒、滚筒、电机装置。滚筒洗衣机的外筒一般使用弹簧及减震器支撑，可在一定范围内晃动。所以在运输过程中，因搬运带来的颠簸或外界的撞击，上述外筒极有可能与洗衣机外壳发生碰撞，引起洗衣机磕伤或形变，从而影响洗衣机的外观或者使用性能。因而在滚筒洗衣机的包装运输过程中，上述外筒的固定尤为重要。
申请号为CN108216926A的中国专利公开了一种滚筒洗衣机包装结构，其通过螺栓固定结构进行洗衣机外筒的固定。所述螺栓固定结构包括包装套管、包装缓冲垫、包装垫片、以及包装螺栓。包装螺栓依次穿过包装垫片、包装缓冲垫、包装套管及洗衣机箱体后板孔，与洗衣机外筒螺纹连接。
在上述专利文献中，虽然设有螺栓固定结构，但是所述螺栓固定结构中的包装缓冲垫通常为橡胶件，其与洗衣机后板直接接触，在洗衣机运输过程中易被磨损，导致包装螺栓失效，失去减震抗噪的作用。这对滚筒洗衣机的外观性能和使用性能构成很大威胁。
另外，现有包装螺栓在滚筒洗衣机使用前必须拆除，使得滚筒洗衣机后板包装螺栓安装孔裸露在外。洗衣机箱体通常为金属材料，锋利的孔边容易划伤物体或人体皮肤，存在较大安全隐患。
有鉴于此特提出本发明。
发明内容
本发明旨在解决现有技术中存在的技术问题。为此，本发明的一个目的在于提出一种用于洗衣机包装的防护部件，用以隔离包装缓冲垫和洗衣机后板，保护包装螺栓。
本发明的另一个目的在于提出一种洗衣机包装装置，所述洗衣机包装装置包括上述防护部件。
本发明采用技术方案的基本构思是：一种用于洗衣机包装的防护部件，包括限位段、翻边和支撑段，所述翻边与所述限位段的一端垂直连接；所述支撑段连接于所述限位段的另一端，向所述翻边一侧倾斜；所述支撑段与所述翻边之间具有一间距。
根据本发明的一些实施例，所述限位段为弧形或管形。
根据本发明的一些实施例，所述翻边面向和背向所述支撑段的第一表面和第二表面为平面。
进一步地，所述防护部件为一种或几种可弹性变形材料，优选的，所述防护部件为高分子材料和/或复合材料。
根据本发明实施例的洗衣机包装装置，所述包装装置包括连接件、缓冲垫，所述连接件贯穿洗衣机后板与洗衣机外筒连接，所述缓冲垫套在所述连接件上位于所述洗衣机后板和所述连接件之间；所述包装装置包括防护部件，所述防护部件包括限位段、翻边和支撑段，所述翻边与所述限位段的一端垂直连接，所述支撑段连接于所述限位段的另一端，向所述翻边一侧倾斜,所述支撑段与所述翻边之间具有一间距；所述翻边设置在所述缓冲垫与所述洗衣机后板之间；所述限位段位于所述缓冲垫与所述洗衣机后板的轴向间隙内；所述支撑段的端面抵靠所述洗衣机后板的内侧面。
根据本发明实施例的洗衣机包装装置，所述翻边的第一表面与所述缓冲垫的不同外径段的过渡面贴合，所述翻边的第二表面与所述洗衣机后板的外侧面贴合。
进一步地，所述翻边的径向尺寸大于或等于所述缓冲垫的过渡面的径向尺寸。
进一步地，所述限位段与所述缓冲垫的圆柱曲面贴合。
根据本发明实施例的洗衣机包装装置，所述防护部件为沿所述缓冲垫柱体外圆轮廓线周向排布的若干分体部件和/或一个整体部件。
进一步地，所述防护部件的硬度大于所述缓冲垫的硬度并小于所述洗衣机后板的硬度。
采用上述技术方案后，本发明与现有技术相比具有以下有益效果。
在滚筒洗衣机包装装置上增加防护部件，一方面能够防止缓冲垫与洗衣机后板直接接触，起隔离防护作用，避免洗衣机后板磨损缓冲垫，间接保护包装螺栓，使其能够起到减震抗噪 作用；另一方面安装防护部件能够起紧固作用，能够减少滑动摩擦对缓冲垫造成损伤，使得包装螺栓的固定更可靠；同时防护部件能够防止洗衣机后板穿入部周圈在运输过程中因颠簸和撞击而发生变形，便于下次使用。
另在运输完成拆除包装装置后，可将防护部件保留在箱体后板上，有效防止穿入部边缘划伤物体或人体皮肤，降低安全隐患。
同时，本发明结构简单，效果显著，适宜推广使用。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对实施例中的技术方案进行清楚、完整地描述，以下实施例用于说明本发明，但不用来限制本发明的范围。
在本发明的描述中，需要说明的是，术语“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
在本发明的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相 连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本发明中的具体含义。
如图1所示，本发明实施例中介绍了一种用于洗衣机包装的防护部件，所述防护部件包括限位段1、翻边2和支撑段3。
如图2所示，翻边2与限位段1的一端垂直连接，支撑段3连接于限位段1的另一端，向翻边2一侧倾斜，支撑段3与翻边2之间具有一间距。支撑段3与限位段1之间形成一空间，该空间用于防护部件100安装于孔内时容纳部分变形的支撑段3，支撑段3与翻边2之间的间距用于夹持被保护件，提高结构稳定性，可有效防止被保护件磕伤或发生变形。整个防护部件100结构简单，使用方便。进一步地，防护部件100采用一体成型方式制造，可有效简化生产过程，降低制造难度和制造成本，提高生产效率。
根据本发明的一些实施例，限位段1为弧形或管形，可用于防护外形为弧形的被保护件。
根据本发明的一些实施例，翻边2面向和背向所述支撑段3的第一表面和第二表面为平面，便于加工成型，降低生产成本。增大与被保护件的接触面积，保证被保护件的表面质量。
进一步地，防护部件100为一种或几种可弹性变形材料，使防护部件100不仅能够用于弧形边的保护，还能够用于孔的防护和固定。优选的，所述防护部件100为高分子材料和/或复合材料，因而可根据防护部件100的使用条件选择材料或选择材料组合，在保证其使用性能和使用寿命的前提下有效降低防护部件100的成本。
根据本发明的一些实施例，如图3所示，本发明实施例中还介绍了一种包装装置，所述包装装置包括缓冲垫4和连接件5，缓冲垫4穿过洗衣机后板6的穿入部，连接件5穿过缓冲垫4与洗衣机外筒连接，洗衣机包装装置还包括上述防护部件100，防护部件100设置在缓冲垫4与洗衣机后板6之间。连接件5贯穿洗衣机后板6与洗衣机外筒连接，缓冲垫4套在连接件5上位于洗衣机后板6和连接件5之间。包装装置还包括上述防护部件100，防护部件100包括限位段1、翻边2和支撑段3，翻边2与限位段1的一端垂直连接，支撑段3连接于限位段1的另一端，向翻边2一侧倾斜,支撑段3与翻边2之间具有一间距。翻边2设置在缓冲垫4与洗衣机后板6之间，限位段1位于缓冲垫4与洗衣机后板6的轴向间隙内，用于隔离缓冲垫4与洗衣机后板6，保护缓冲垫4不受洗衣机后板6的刮伤和磨损。支撑段3的端面抵靠洗衣机后板6的内侧面，与翻边2和限位段1形成三角支撑结构，为洗衣机后板6提供支撑。
优选的，连接件5为包装螺栓，包装装置还包括垫片7、包装套管8。作为本发明的一个实施例，连接件5首先穿过垫片7，然后穿过包装套管8、缓冲垫4和防护部件，最后将整个包装装置穿过洗衣机后板6与洗衣机外筒螺纹连接。缓冲垫4由半径不同的两个圆柱段连接而成，外轮廓为“凸”字形，在缓冲垫4中心开有与连接件5套接的通孔。包装套管8的一端向缓冲垫4的通孔内部延伸，与缓冲垫4的通孔内壁形成倒钩连接，其另一端抵住洗衣机外筒的表面。垫片7的安装能够起到减震作用。包装套管8与缓冲垫4的连接方式增加了整体结构的稳定性，同时包装套管8通常为橡胶材料，对包装装置的减震作用做出一定贡献。进一步的，包装套管8套在连接件5上，能够保护连接件5的螺纹不受损伤。
进一步地，翻边2的第一表面与缓冲垫4的不同外径段的过渡面贴合，防止缓冲垫4与防护部件100的轴向相对运动，减少缓冲垫4的摩擦磨损。翻边2的第二表面与洗衣机后板6的外侧面贴合。当洗衣机在运输过程中受到碰撞或冲击时，冲击力能够通过翻边2迅速向洗衣机后板6扩散，防止洗衣机后板6穿入部周圈区域发生变形，同时这种结构能防止缓冲垫4和洗衣机后板6直接接触，避免因相对运动对缓冲垫4造成磨损。
进一步地，翻边2的径向尺寸大于或等于缓冲垫4的过渡面的径向尺寸，增大翻边2与缓冲垫4的接触面积能够增加受力面积，降低缓冲垫4变形的几率。
进一步地，限位段1与缓冲垫4的圆柱曲面贴合，增大两者的接触面积，利于冲击力的传导扩散。
根据本发明实施例的洗衣机包装装置，防护部件100为沿缓冲垫4柱体外圆轮廓线周向排布的若干分体部件和/或一个整体部件，可根据包装装置的实际工作环境选择防护部件100的结构形式。优选的，所述防护部件100设置为沿所述缓冲垫柱体外圆轮廓线周向间隔排列的分段件，各分段件通过一定宽度的筋桥式连接形成整体部件。该结构在保证使用效果的前提下可降低材料成本，同时提供缓冲垫4的弹性变形空间，利于冲击力的释放。
优选地，防护部件100的硬度大于缓冲垫4的硬度并小于洗衣机后板6的硬度，此硬度配合方式一方面能够保护缓冲垫4不被磨损，另一方面保证洗衣机后板6不被损坏。
以上所述仅是本发明的较佳实施例而已，并非对本发明作任何形式上的限制，虽然本发明已以较佳实施例揭露如上，然而并非用以限定本发明，任何熟悉本专利的技术人员在不脱离本发明技术方案范围内，当可利用上述提示的技术内容作出些许更动或修饰为等同变化的等效实施例，但凡是未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与修饰，均仍属于本发明方案的范围内。
