下面结合图1-图12描述本申请的线束固定结构及电器箱体。
参考图1，本实施例提供一种线束固定结构，其中线束3用于穿出箱体11上的出线孔，该线束固定结构包括固定圈2。固定圈2用于套设于线束3。固定圈2设于线束3和出线孔111之间，起到线束3在出线孔111处的固定密封作用。参考图2，所述固定圈2的内部沿轴向设有贯穿的线束孔23。线束3从线束孔23中穿过。所述固定圈2的外壁沿轴向的中间部位设有一圈卡槽21，所述卡槽21用于与出线孔的侧边匹配插接。即固定圈2的外壁面上在沿轴向的中间部位具有一段截面尺寸较小的槽段，使得固定圈2的外壁面上在中间部位形成卡槽21，出线孔的侧边可对应插入固定圈2外壁上的卡槽21中，固定圈2的两端端部部位22卡在出线孔111的侧边的两侧，从而将固定圈2固定在出线孔111处，避免脱落。
参考图1和图2，所述出线孔的内壁设有定位块，所述卡槽21的槽底上设有与所述定位块对应的定位槽24。在固定圈2安装完成时，出线孔111的内壁与固定圈2上卡槽21的槽底贴合接触；且出线孔111内壁上的定位块对应插入固定圈2卡槽21上的定位槽24中。可更好的实现固定圈2的固定，进而实现线束更好的固定。
本实施例提供的一种线束固定结构，在线束和出线孔111之间设置固定圈2，可较好的实现线束在出线孔111处的固定和密封，实现线束的有序稳定放置；且固定圈2套设于线束可对线束起到防磨损保护作用；另外，固定圈2通过卡槽21和定位槽24与出线孔111匹配连接，可提高固定圈2固定的稳定性；采用该固定圈2固定线束，固定方式简单，固定牢靠。
进一步地，可在出线孔的内壁相对两侧设置两个定位块，在固定圈2卡槽21的槽底上对应设置两个定位槽24，进一步地提高固定圈2与出线孔111配合的牢固性和稳定性。
进一步地，固定圈2中间卡槽21部位的外径可略大于出线孔111的内径，使得出线孔111与固定圈2的卡槽21部位过盈配合，提高固定圈2设置的稳定性和牢固性。
在上述实施例的基础上，进一步地，参考图2和图3，所述固定圈2沿轴向位于所述卡槽21两侧的端部部位22分别呈锥形结构，且所述端部部位22靠近端面的截面尺寸小于靠近卡槽21的截面尺寸。固定圈2沿轴 向分为两端的端部部位22以及中间的卡槽21部位。端部部位22的截面尺寸大于卡槽21部位的截面尺寸。设置端部部位22呈锥形结构，且端部部位22靠近端面的截面尺寸较小，可便于固定圈2的安装。
进一步地，在另一个实施例中，固定圈2沿轴向位于卡槽21两侧的端部部位22还可呈飞碟型结构，即端部部位22的截面尺寸从端面侧至卡槽21侧先逐渐增大，再逐渐减小，如图3所示。在其他实施例中，端部部位22的形状也可为其他，以端部部位22靠近端面的截面尺寸小于靠近卡槽21的截面尺寸便于在出线孔111处的安装为目的，具体不做限定。
在上述实施例的基础上，进一步地，参考图2和图3，所述固定圈2沿轴向位于所述卡槽21两侧的端部部位22与所述定位槽24对应处分别设有导向槽25。端部部位22上的导向槽25与卡槽21部位上的定位槽24在轴向上对应，从而在安装固定圈2时，便于出线孔111内壁上的定位孔沿导向槽25滑入定位槽24中。
进一步地，参考图2和图3，固定圈2在定位槽24处的截面尺寸小于固定圈2在导向槽25处的截面尺寸；即定位槽24相对导向槽25呈凹陷状，使得在定位块插入定位槽24时，定位块不会轻易滑动至导向槽25中，提高固定圈2的稳定性和牢固性。
在上述实施例的基础上，进一步地，参考图4，所述固定圈2沿周向分为两部分，所述固定圈2的两部分拼接连接。设置固定圈2沿周向由两部分拼接连接，可便于固定圈2与线束3的安装。
优选的，本实施例中固定圈2可对称分为两部分。固定圈2的两部分的内壁分别为半圆结构，从而固定圈2的两部分的内壁拼接连接形成线束孔23。进一步地，固定圈2也可沿周向分为三部分或其他数量进行拼接连接，以能拼接形成固定圈2且便于固定圈2安装于线束3为目的，具体不做限定。
在上述实施例的基础上，进一步地，参考图4，所述固定圈2的两部分之间设有匹配的安装柱27和安装孔26。即在固定圈2其中一部分的拼接面上设有安装柱27，在另一部分拼接面的对应处设有安装孔26。从而在固定圈2的两部分拼接时，安装柱27对应插入安装孔26中实现两部分的连接。
进一步地，安装柱27与安装孔26可过盈配合连接。即安装柱27的外径尺寸可略大于安装孔26的内径尺寸，提高固定圈2两部分拼接连接的牢固性。
在上述实施例的基础上，进一步地，参考图5，所述固定圈2的其中一部分的拼接面上在所述线束孔23的一侧设有安装柱27，在所述线束孔23的另一侧交错设有安装孔26。即位于固定圈2该部分拼接面一侧的安装柱27和位于另一侧的安装孔26沿轴向交错设置。即在固定圈2任一部分的拼接面上既设有安装柱27，又设有安装孔26，安装柱27和安装孔26分布在两侧且上下交错分布。而在固定圈2另一部分的拼接面上相应设置匹配的安装孔26和安装柱27。
安装柱27和安装孔26的该分布结构有利于提高固定圈2两部分拼接连接的牢固性。进一步地，固定圈2任一部分的拼接面上安装柱27和安装孔26的具体设置数量和分布可灵活设置，以能实现牢固拼接形成固定圈2为目的，具体不做限定。
进一步地，参考图6、图7和图8，多个线束与多个固定圈2一一对应连接，多个线束一一对应穿过多个出线孔111，可实现线束的有序固定。
在上述实施例的基础上，进一步地，参考图9，所述箱体11上设有贯穿的线束框112。线束框112为贯穿箱体11的开口结构。所述线束框112处设有匹配的开合板113。开合板113的尺寸形状与线束框112匹配，在开合板113关闭时箱体11的线束框112呈封闭状。所述开合板113的第一侧与所述线束框112的第一侧可转动连接。所述开合板113的第二侧与所述线束框112的第二侧之间构造有所述出线孔。
具体的，可在线束框112第二侧开设第一半包围孔，在开合板113的第二侧对应开设第二半包围孔，第一半包围孔和第二半包围孔拼接形成出线孔；即开合板113的第二侧和线束框112的第二侧可拼接形成出线孔。通过开合板113的转动，可实现线束框112的打开和关闭。进一步地，参考图1，线束框112第二侧的第一半包围孔的圆弧角可大于180°，即第一半包围孔的角度大于半圆孔。在安装固定圈2时，可先将固定圈2安装在第一半包围孔处，然后转动开合板113关闭完成安装。设置第一半包围孔的角度大于半圆孔，可提高固定圈2与第一半包围孔配合的牢固稳定性， 降低安装时固定圈2脱落的风险，便于安装。
参考图10，可打开开合板113，此时出线孔111呈半包围结构，可便于线束3的穿过以及固定圈2的安装。可在开合板113打开时穿过线束3且安装固定圈2，将固定圈2拼接套设在线束3上，且固定圈2上的定位槽24和卡槽21可与线束框112第二侧的出线孔111侧边匹配插接。然后再转动开合板113，使得开合板113第二侧的出线孔111侧边穿过固定圈2的端部部位22，将开合板113第二侧的出线孔111侧边上的定位块对应插入固定圈2的定位槽24中，关闭开合板113，完成线束的固定，如图12所示。
在上述实施例的基础上，进一步地，参考图11，所述开合板113的第一侧与所述线束框112的第一侧一体连接，且所述开合板113的第一侧设有减薄区域1131。
在上述实施例的基础上，进一步地，参考图11，所述减薄区域1131设有锯齿结构1132。可便于开合板113的转动，有利于提高结构使用寿命。
在上述实施例的基础上，进一步地，本实施例中出线孔111还可直接为开设在箱体11上的开孔。这种结构不需要包含开合板，即开合板与线束框合为一体连接，只保留出线孔及其定位块。可利用固定圈2端部部位的锥形端部挤入出线孔111进行安装。在上述实施例的基础上，进一步地，本实施例提供一种电器箱体11，该电器箱体11包括上述任一实施例所述的线束固定结构。
在上述实施例的基础上，进一步地，本实施例提供一种电器箱体11中电脑板线束的固定结构，主要解决空调外机电器箱体11中电脑板线束固定不牢靠，线束杂乱、线束易磨损的问题。该线束的固定结构主要在线束和出线孔111之间设置固定圈2。如图4，线束固定圈2采用对称对开式结构，由一对的半固定圈2组成。整体上下左右对称，采用如橡胶之类的软性塑料制作，具备良好的弹性变形及密封性。左边固定圈2与右边固定圈2完全相同，二者结合形成一个线束固定圈2。
如图5，以一半固定圈2为例进行说明，中间中空，用于走线，上端和下端呈锥形，中间呈柱形，在固定圈2配合面的左下角开设安装柱27，右上角设置安装孔26。一对半固定圈2通过安装柱27与安装孔26进行的 过盈配合形成一个线束固定圈2。
如图8，线束固定圈2的中间线束孔23用于走线，线束孔23的直径略小于线的直径，依靠弹性变形固定走线，并起到密封作用。线束固定圈2抱紧走线后，通过定位槽24安装在箱体11出线孔111上，并与出线孔111上的定位块配合。参考图1，箱体11线束框112第二侧的第一半包围孔呈圆形，并开设缺口，缺口不得大于半圆，以便更牢靠地固定。安装时首先将线束固定圈2安装到线束3上，如图6；再将线束固定圈2固定到电器箱体11的线束固定圈2孔上，如图8；然后转动开合板113关闭，如图12，完成安装。
本实施例提供的电脑板线束的固定方式；线束固定圈2设计为对开式结构；采用该固定圈2固定线束，固定方式简单，固定牢靠，橡胶类软性塑料对线束能起一定的防磨损保护。
