具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
为了清楚地描述本申请实施例，参见图1，下文所述的壳体1的上下方向是与插孔11所在的壳壁垂直的方向。也即是，以插孔11所在的壳壁为上，以插孔11所在的壳壁相对的一个壳壁为下的方向。或者，参见图2，壳体1的上下方向是以上壳13为上，以底壳12为下的方向。
本申请提供的多国转换器通过设置若干个自锁板3，在使用其中一插销组件2时，该插销组件2伸出时可推动相邻的自锁板3移动以避开该插销组件2，且相邻的自锁板3同时带动其余自锁板3移动，使若干个自锁板3分别抵挡其余插销组件2，以防止其余插销组件2相对壳体1伸出，从而其它插销组件2无法伸出壳体1外，有效防止其它插销组件2伸出壳体1外而导致用户触电，从而保证该多国转换器安全性能好。同时，通过将各个自锁板3沿插销组件2的伸缩方向设置，也即是各个自锁板3所在的平面与壳体1的上下方向平行，自锁板3可在壳体1内移动以避开或阻挡对应的插销组件2，自锁板3移动行程小，占用空间小，结构简单且紧凑。
请参照图1-图4，该多国转换器包括：壳体1，壳体1具有插孔11；位于壳体1内的若干个插销组件2，插销组件2可沿壳体1的上下方向伸缩，插销组件2可收容于壳体1内或相对壳体1伸出；以及位于壳体1内的若干个自锁板3，自锁板3所在的平面与壳体1的上下方向平行，若干个自锁板3彼此相邻且可在壳体1内移动；其中一插销组件2相对壳体1伸出时，伸出的插销组件2推动相邻的自锁板3移动以避开该伸出的插销组件2，且相邻的自锁板3同时带动其余自锁板3移动，使若干个自锁板3分别抵挡其余插销组件2相对壳体1伸出。
本申请实施例的多国转换器通过设置若干个自锁板3，在使用若干个插销组件2中的一个插销组件2时，该插销组件2伸出时可推动相邻的自锁板3移动以避开该伸出的插销组件2，且相邻的自锁板3同时带动其余自锁板3移动，使若干个自锁板3分别抵挡其余插销组件2相对壳体1伸出，从而其他插销组件2无法伸出壳体1外，有效防止其它插销组件2伸出壳体1外而导致用户触电，从而保证该多国转换器安全性能好。同时，通过将各个自锁板3沿插销组件2的伸缩方向设置，也即是各个自锁板3所在的平面与壳体1的上下方向平行，自锁板3可沿壳体1的左右方向移动以避开或阻挡对应的插销组件2，结构简单，且自锁板3占用空间小。
本申请实施例中，参见图2，壳体1包括底壳12和与底壳12组配形成完整收容空间的上壳13，插销组件2可沿底壳12和上壳13的上下方向伸缩。上壳13表面具有多个供用户接通电源的插孔11。
需要说明的是，该多国转换器包括位于底壳12与上壳13形成的收容空间内且与多个插孔11一一对应的多个标准插套组。这样，在通过多国转换器进行插座的转换时，能够使得用电设备的插头穿过任一个插孔11插入对应的标准插套组。多个标准插套组可以对应多个不同国家的标准插座，这样，通过多国转换器能够实现若干个插销组件2中的任一插销组件2对应的标准插座与多个标准插套组中任一个标准插套组对应的标准插座之间的转换。
请参照图5-图6，作为本申请的一个实施例，多国转换器还包括设于壳体1内的基座4，基座4包括底座41、以及位于底座上且相对的两侧隔板42，两侧隔板42之间形成有限位槽43，自锁板3位于限位槽43内并可沿限位槽43移动。这样，通过设置限位槽43对自锁板3进行限位，保证自锁板3在移动过程中平稳运动。
可选地，隔板42为条状矩形结构，隔板42的长度方向与壳体1的上下方向平行，隔板42的宽度方向与自锁板3的移动方向平行。两侧隔板42之间的间隔(限位槽43的宽度)可以略大于自锁板3的厚度，以避免在自锁板3移动过程中发生较大的晃动，从而与隔板42之间因碰撞产生噪声。
需要说明的是，自锁板3的底部与限位槽43的槽底光滑接触，以便于在沿移动方向对自锁板3施加作用力时，自锁板3可以在限位槽43内移动。当然，自锁板3的底部与限位槽43的槽底也能够通过其他方式接触，比如自锁板3的底部具有滚轮，滚轮能够限位在限位槽43内，这样自锁板3能够基于滚轮在限位槽43内移动，同时也能避免自锁板3从限位槽43内脱出的可能。
还需要说明的是，参见图5或图6，基座4包括位于底座41上的支撑柱44，支撑柱44朝向上壳13的方向延伸。支撑柱44的数量与插销组件2的数量相同且一一对应，每个插销组件2安装在对应的支撑柱44上，并可沿支撑柱44滑动，以保证插销组件2只能在壳体1的上下方向移动。
本申请实施例中，参照图4和图7，插销组件2均包括具有延长臂211的固定座21、与固定座21连接的拨动按钮22以及固定于固定座21上的插脚23，拨动按钮22可沿壳体1的上下方向滑动并带动插脚23相对壳体1伸出或收容于壳体1内。自锁板3包括支撑部31和固定在支撑部31顶部的锁定部32，锁定部32在移动方向上的两侧具有斜面321。延长臂211沿自锁板3的移动方向依次排列，每个自锁板3位于相邻两个延长臂211之间，且斜面321的至少一部分低于相邻的延长臂211。这样，插销组件2的固定座21的延长臂211与自锁板3的锁定部32的斜面321配合，并可带动自锁板3在相邻两个延长臂211 之间移动。
其中，延长臂211的延伸方向与壳体1的上下方向垂直，且与自锁板3的移动方向垂直。当然，延长臂211的延伸方向也可以为其他方向，只要延长臂211在壳体1的上下方向移动时能够与自锁板3的锁定部32的斜面配合接触即可。支撑部31的顶部的尺寸小于或等于锁定部32的底部的尺寸，避免支撑部31的顶部对延长臂211的阻挡。
可选地，锁定部32在移动方向上的最大尺寸等于相邻的两个延长臂211的中心点之间的距离，这样，在一个插销组件2伸出壳体1后，若干个自锁板3位于其余插销组件2的延长臂211的正下方，从而避免其余插销组件2伸出壳体1外。当然，插销组件2的数量小于一定数值时，相邻的两个延长臂211的中心点之间的距离小于锁定部32在移动方向上的最大尺寸，且大于锁定部32与斜面321在移动方向上的最大尺寸差值，只要能够限定其余插销组件2伸出壳体1即可。
在使用其中一插销组件2时，通过拨动该插销组件2对应的拨动按钮22，拨动按钮22带动固定座21沿壳体1向下移动，从而固定座21上的插脚23相对壳体1伸出。该插销组件2伸出的过程中，该插销组件2的固定座21向下移动，带动该插销组件2的固定座21的延长臂211向下移动，并对与其相邻的自锁板3的斜面321施加作用力，此时该作用力基于与相邻的斜面321之间的相互作用分解为沿壳体1上下方向的作用力和沿自锁板3移动方向的作用力。沿壳体1上下方向的作用力在底座41对自锁板3的反向作用力下抵消，沿自锁板3移动方向的作用力推动相邻的自锁板3移动，使该自锁板3移动以避开该插销组件2，并通过该插销组件2的延长臂211对移动后的自锁板3进行限位。同时该自锁板3推动其余自锁板3移动，使若干个自锁板3的锁定部32的斜面321的至少一部分低于其他插销组件2的固定座21的延长臂211。由于该插销组件2的固定座21的延长臂211能够对该自锁板3进行限位，从而通过该自锁板3能够实现对其余自锁板3的限位，这样通过若干个自锁板3的锁定部32 的斜面321抵挡位于上方的其它插销组件2的固定座21的延长臂211，从而使其它插销组件2的固定座21的延长臂211无法相对壳体1移动，进而防止其它插销组件2相对壳体1伸出，保证在一插销组件2伸出时，其余插销组件2无法相对壳体1伸出，安全性能好。
可选地，支撑部31为条状矩形结构，锁定部32为锐角三角形，或者为非直角梯形。
需要说明的是，上述描述的支撑部31和锁定部32只是自锁板3的一种组成方式，在其他一些实施例中，自锁板3还存在其他的组成方式。作为本申请的一个实施例，参见图8，每个自锁板3包括自锁板本体34、以及自锁板本体34在移动方向上的两侧分别延伸的凸起35，每个凸起35的上部端面为斜面321。其中一插销组件2相对壳体1伸出时，该插销组件2的固定座21的延长臂211与相邻的自锁板3的凸起35的斜面321配合接触并推动相邻的自锁板3移动，且带动其余自锁板3移动，使若干个自锁板3的凸起35的斜面321分别抵挡其余插销组件2的固定座21的延长臂211，使其余插销组件2无法相对壳体1伸出。
延长臂211与凸起35的斜面321的配合并推动相邻的自锁板3移动，以及抵挡其余插销组件2无法相对壳体1伸出的具体过程与上述描述的过程相同或相似，本申请实施例对此不再赘述。
可选地，自锁板本体34为条状矩形结构，凸起35为条状凸起。
本申请实施例中，通过自锁板3的凸起35的斜面321与插销组件2的固定座21的延长臂211抵挡配合，限制了延长臂211的移动，进而限制了固定座21的移动，从而防止固定座21上的插脚23相对壳体1伸出，由于自锁板3的凸起35的斜面321直接与插销组件2的固定座21的延长臂211配合抵接，无需直接对插脚23进行抵挡，有效防止插脚23的损坏。
其中，每个凸起35的上部的端面也可以为曲面，只要在插销组件2的固定座21的延长臂211对相邻的自锁板3的曲面施加作用力时，该作用力基于曲面 分解后的力包括沿自锁板3移动方向的力即可。这样，插销组件2的固定座21的延长臂211与相邻自锁板3的凸起35的曲面配合接触时，分解后的沿自锁板3移动方向的力推动该自锁板3移动。
请结合参照图7，作为本申请的一个实施例，锁定部32为非直角梯形，锁定部32的顶部具有一定位部33，定位部33与相邻的延长臂211在自锁板3的移动方向上的投影至少部分重合。这样通过设置定位部33，定位部33与插销组件2的固定座21的延长臂211配合接触以限制每个自锁板3的移动行程，保证自锁板3与各插销组件2的固定座21的延长臂211准确配合。
可选地，定位部33为矩形结构。在其他一些实施例中，定位部33也可以为其它形状的结构，只要定位部33与相邻的延长臂211在自锁板3的移动方向上至少部分重合，从而能够在相邻的延长臂211的阻挡作用下限制该自锁板3的行程即可。
可选地，延长臂211高于相邻的斜面321，相邻两个延长臂211之间的距离等于定位部33和斜面321在移动方向上的尺寸总和。这样，在一个延长臂211推动相邻的自锁板3移动后，其余延长臂211基于自锁板3的定位部33对若干个自锁板3进行限位，以避免若干个自锁板3的移动距离过大，进而将若干个自锁板3限位在其余延长臂211的正下方，以限制其余延长臂211的移动。
需要说明的是，参见图8，当自锁板3的组成部分包括自锁板本体34和凸起35时，自锁板本体34的顶部凸起以形成定位部33。
还需要说明的是，本申请实施例中，在插销组件2的固定座21的延长臂211在壳体1的上下方向移动时，延长臂211需要推动自锁板3移动，而自锁板3位于限位槽43内，因此在壳体1的上下方向上，延长臂211必然和形成限位槽43的至少一侧隔板42存在重合部分。而为了避免该至少一侧隔板42阻碍延长臂211的移动，该至少一侧隔板42的高度可以基于固定座21的高度进行设置，只要不妨碍插脚23伸出壳体1外即可。当然，为了避免该至少一侧隔板42阻碍延长臂211的移动，该至少一侧隔板42中的每侧可以包括若干个隔板 42，且该若干个隔板42与若干个延长臂211在自锁板3的移动方向上交替排列，也即是同一侧的隔板42与若干个延长臂211在自锁板3的移动方向上交替排列，以保证每个延长臂211移动时，基于同一侧隔板42中相邻两个隔板42之间的间隔顺利移动。
可选地，若干个自锁板3中任意相邻两个自锁板3在移动方向上的投影至少部分重合。在一些实施例中，若干个自锁板3共平面，此时自锁板3为沿直线方向移动。在又一些实施例中，若干个自锁板3也可以共圆弧面，此时自锁板3沿圆弧线方向移动。
可选地，若干个自锁板3的数量比若干个插销组件2的数量少1。
在本申请的一个实施例中，同一侧插销组件2的延长臂211的延伸方向相同。不同侧插销组件2的延长臂211的延伸方向相向，且两侧插销组件2的延长臂交替排列。
在本申请的一个实施例中，每个插销组件2的延长臂211的延伸方向均朝向同一个中心点。相应地，若干个自锁板3分布在一个圆周上，此时，自锁板3的移动方向为圆周方向，若干个自锁板的数量等于若干个插销组件2的数量。
接下来将结合具体的示例对本申请的多国转换器进行介绍。
作为本申请的一个实施例，参见图9，若干个插销组件2包括第一插销组件2a、第二插销组件2b及第三插销组件2c；若干个自锁板3包括第一自锁板3a和第二自锁板3b，第一插销组件2a包括具有第一延长臂211a的第一固定座21a、与第一固定座21a连接的第一拨动按钮22a以及固定于第一固定座21a上的第一插脚23a；第二插销组件2b包括具有第二延长臂211b的第二固定座21b、与第二固定座21b连接的第二拨动按钮22b以及固定于第二固定座21b上的第二插脚23b；第三插销组件2c包括具有第三延长臂211c的第三固定座21c、与第三固定座21c连接的第三拨动按钮22c以及固定于第三固定座21c上的第三插脚23c。
第一自锁板3a设于第一插销组件2a的第一固定座21a的第一延长臂211a和第二插销组件2b的第二固定座21b的第二延长臂211b之间，第二自锁板3b设于第二插销组件2b的第二固定座21b的第二延长臂211b和第三插销组件2c的第三固定座21c的第三延长臂211c之间。
第一自锁板3a可在第一插销组件2a的第一固定座21a的第一延长臂211a和第二插销组件2b的第二固定座21b的第二延长臂211b之间移动并抵挡第一插销组件2a的第一固定座21a的第一延长臂211a或第二插销组件2b的第二固定座21b的第二延长臂211b；第二自锁板3b可在第二插销组件2b的第二固定座21b的第二延长臂211b和第三插销组件2c的第三固定座21c的第三延长臂211c之间移动并阻挡第二插销组件2b的第二固定座21b的第二延长臂211b或第三插销组件2c的第三固定座21c的第三延长臂211c。
参照图10，本申请实施例中，第一自锁板3a包括第一自锁板本体34a、以及第一自锁板本体34a在移动方向上的两侧分别延伸的第一凸起35a和第二凸起35b，第一凸起35a的上部端面为第一斜面321a，第二凸起35b的上部端面为第二斜面321b，第一自锁板本体34a的顶部凸起形成有第一定位部33a；第二自锁板3b包括第二自锁板本体34b、以及第二自锁板本体34b在移动方向上的两侧分别延伸的第三凸起35c和第四凸起35d，第三凸起35c的上部端面为第三斜面321c，第四凸起35d的上部端面为第四斜面321d，第二自锁板本体34b的顶部凸起形成有第二定位部33b。
第一插销组件2a的第一固定座21a的第一延长臂211a设于第一定位部33a的一侧并可与第一斜面321a滑动接触，第二插销组件2b的第二固定座21b的第二延长臂211b设于第一定位部33a和第二定位部33b之间并可与第二斜面321b和第三斜面321c滑动接触，第三插销组件2c的第三固定座21c的第三延长臂211c设于第的二定位部33b一侧并可与第四斜面321d滑动接触。
如图9和图11所示，本实施例中，当使用第一插销组件2a时，拨动第一插销组件2a的第一拨动按钮22a，第一插销组件2a的第一插脚23a下移，第一 插销组件2a的第一固定座21a的第一延长臂211a与第一自锁板3a的第一斜面321a滑动接触并不断向下移动，以推动第一自锁板3a向右移动。这样直到第一自锁板3a的第一定位部33a与第二插销组件2b的第二固定座21b的第二延长臂211b配合接触，也即是第一定位部33a抵触在第二延长臂211b上，此时，第一自锁板3a的第一凸起35a的第一斜面321a避开第一延长臂211a，且第一自锁板3a的第二凸起35b的第二斜面321b位于第二插销组件2b的第二固定座21b的第二延长臂211b的下方，以抵挡第二插销组件2b的第二固定座21b的第二延长臂211b，使第二插销组件2b的第二固定座21b的第二延长臂211b无法下移，从而防止第二插销组件2b相对壳体1伸出。同时，第一自锁板3a在向右移动过程中推动第二自锁板3b向右移动，使第二自锁板3b的第二定位部33b与第三插销组件2c的第三固定座21c的第三延长臂211c配合接触，此时第二自锁板3b的第四凸起35d位于第三插销组件2c的第三固定座21c的第三延长臂211c的下方以阻挡第三插销组件2c的第三固定座21c的第三延长臂211c，使第三插销组件2c的第三固定座21c无法下移，从而实现第二插销组件2b及第三插销组件2c的自锁，保证第二插销组件2b及第三插销组件2c无法相对壳体伸出，实现自锁功能，起到安全保护作用。
如图9和图12所示，当使用第二插销组件2b时，拨动第二插销组件2b的第二拨动按钮22b，第二插销组件2b的第二插脚23b下移，第二插销组件2b的第二固定座21b的第二延长臂211b同时沿第一自锁板3a的第二斜面321b及第二自锁板3b的第三斜面321c向下运动，并推动第一自锁板3a向左移动，推动第二自锁板3b向右移动，直到第一自锁板3a的第一定位部33a与第一插销组件2a的第一固定座21a的第一延长臂211a配合接触，且第二自锁板3b的第二定位部33b与第三插销组件2c的第三固定座21c的第三延长臂211c配合接触，也即是第一定位部33a抵触在第一延长臂211a上，且第二定位部33b抵触在第三延长臂211c上，此时第一自锁板3a的第二凸起35b的第二斜面321b和第二自锁板3b的第三凸起35c的第三斜面321c避开第二延长臂211b，第一自 锁板3a的第一凸起35a的第一斜面321a位于第一插销组件2a的第一固定座21a的第一延长臂211a的下方，以抵挡第一插销组件2a的第一固定座21a的第一延长臂211a，且第二自锁板3b的第四凸起35d的第四斜面321d位于第三插销组件2c的第三固定座21c的第三延长臂211c的下方，以抵挡第三插销组件2c的第三固定座21c的第三延长臂211c，从而第一插销组件2a及第三插销组件2c无法下移，保证第一插销组件2a及第三插销组件2c在第二插销组件2b伸出时无法相对壳体伸出，实现自锁功能。
如图9和图13所示，当使用第三插销组件2c时，拨动第三插销组件2c的第三拨动按钮22c，第三插销组件2c的第三插脚23c下移，第三插销组件2c的第三固定座21c的第三延长臂211c沿第二自锁板3b的第四斜面311d向下运动，并推动第二自锁板3b向左移动，第二自锁板3b推动第一自锁板3a向左移动，直到第一自锁板3a的第一定位部33a与第一插销组件2a的第一固定座21a的第一延长臂211a配合接触，且第二自锁板3b的第二定位部33b与第二插销组件2b的第二固定座21b的第二延长臂211b配合接触，也即是第一定位部33a抵触在第一延长臂211a上，且第二定位部33b抵触在第二延长臂211b上，此时第二自锁板3b的第四凸起35d的第四斜面321d避开第三延长臂211c，且第一自锁板3a的第一凸起35a的第一斜面321a位于第一插销组件2a的第一固定座21a的第一延长臂211a的下方，以抵挡第一插销组件2a的第一固定座21a的第一延长臂211a，第二自锁板3b的第三凸起35c的第三斜面321c位于第二插销组件2b的第二固定座21b的第二延长臂211b的下方，以抵挡第二插销组件2b的第二固定座21b的第二延长臂211b，从而第一插销组件2a及第二插销组件2b无法下移，实现第一插销组件2a及第二插销组件2b的自锁，保证第一插销组件2a及第二插销组件2b在第三插销组件2c伸出时无法相对壳体伸出，实现自锁功能。
如图9所示，作为本申请的一个实施例，插销组件还包括第四插销组件2d；若干个自锁板3还包括第三自锁板3c，第四插销组件2d包括具有第四延长臂 211d的第四固定座21d、与第四固定座21d连接的第四拨动按钮22d以及固定于第四固定座21d上的第四插脚23d。

本申请实施例中，如图10所示，第三自锁板3c包括第三自锁板本体34c、第三自锁板本体34c在自锁板3的移动方向的两侧分别延伸的第五凸起35e和第六凸起35f，第五凸起35e的上部端面为第五斜面321e，第六凸起35f的上部端面为第六斜面321f，第三自锁板本体34c的顶部凸起形成有第三定位部33c；第三插销组件2c的第三固定座21c的第三延长臂211c设于第二定位部33b和第三定位部33c之间并可与第四斜面321d和第五斜面321e滑动接触，第四插销组件2d的第四固定座21d的第四延长臂211d设于第三定位部33c的一侧并可与第六斜面321f滑动接触。
如图9和图14所示，本实施例中，当使用第四插销组件2d时，拨动第四插销组件2d的第四拨动按钮22d，第四插销组件2d的第四插脚23d下移，第四插销组件2d的第四固定座21d的第四延长臂211d沿第三自锁板3c的第六斜面321f向下运动，并推动第三自锁板3c向左移动，第三自锁板3c向左移动过程中推动第二自锁板3b及第一自锁板3a向左运动，直到第三自锁板3c的第三定位部33c与第三插销组件2c的第三固定座21c的第三延长臂211c配合接触，也即是第三定位部33c抵触在第三延长臂211c上，第二自锁板3b的第二定位部33b与第二插销组件2b的第二固定座21b的第二延长臂211b配合接触，也即是第二定位部33b抵触在第二延长臂211b上，第一自锁板3a的第一定位部33a与第一插销组件2a的第一固定座21a的第一延长臂211a配合接触，也即是 第一定位部33a抵触在第一延长臂211a上。此时第一自锁板3a的第一凸起35a的第一斜面321a位于第一插销组件2a的第一固定座21a的第一延长臂211a的下方，以抵挡第一插销组件2a的第一固定座21a的第一延长臂211a，第二自锁板3b的第三凸起35c的第三斜面321c位于第二插销组件2b的第二固定座21b的第二延长臂211b的下方，以抵挡第二插销组件2b的第二固定座21b的第二延长臂211b，第三自锁板3c的第五凸起35e的第五斜面321e位于第三插销组件2c的第三固定座21c的第三延长臂211c的下方，以抵挡第三插销组件2c的第三固定座21c的第三延长臂211c，从而第一插销组件2a、第二插销组件2b及第三插销组件2c无法下移，实现第一插销组件2a、第二插销组件2b及第三插销组件2c的自锁，保证第一插销组件2a、第二插销组件2b及第三插销组件2c在第四插销组件2d伸出时无法相对壳体伸出，实现自锁功能。

作为本申请的一个实施例，第一自锁板3a、第二自锁板3b以及第三自锁板3c位于同一平面。通过将第一自锁板3a、第二自锁板3b以及第三自锁板3c设置在同一平面上，通过将有效节省占用空间，结构紧凑，而且各自锁板之间受力平衡，使各自锁板运动更加平稳。
本申请提供的多国转换器通过设置若干个自锁板，在使用其中一插销组件时，该插销组件相对壳体伸出时可推动相邻的自锁板移动以避开该插销组件，且相邻的自锁板同时带动其余自锁板移动，使若干个自锁板分别抵挡其余插销组件，以防止其余插销组件相对壳体伸出，从而其它插销组件无法伸出壳体外，有效防止其它插销组件伸出壳体外而导致用户触电，从而保证该多国转换器安全性能好。同时，通过将各自锁板沿插销组件的伸缩方向设置，且自锁板可沿壳体的左右方向移动以避开或阻挡对应的插销组件，自锁板移动行程小，占用 空间小，结构简单且紧凑。
以上仅为本申请的可选实施例而已，并不用以限制本申请，凡在本申请的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本申请的保护范围之内。
