具体实施方式
下面结合附图，对本发明的具体实施方式进行详细描述，但应当理解本 发明的保护范围并不受具体实施方式的限制。
除非另有其它明确表示，否则在整个说明书和权利要求书中，术语“包括”或其变换如“包含”或“包括有”等等将被理解为包括所陈述的元件或组成部分，而并未排除其它元件或其它组成部分。
如图3至图5所示(图中箭头代表推力)，根据本发明具体实施方式的金属壳手机卡托孔的防水结构的具体结构包括：SIM卡座21、卡托22、卡托推杆23和防水密封针24。其中，SIM卡座21位于手机PCB板25的上侧，卡托22设置在该SIM卡座21内，用于盛放SIM卡。卡托推杆23设置在SIM卡座21的一侧，其与卡托22联动设置，推动卡托推杆23即可将卡托22顶出壳体从而实现取SIM卡或装SIM卡。金属壳手机的壳体26上开设有与卡托推杆23对应的卡托推杆孔27，防水密封针24设置在该卡托推杆孔27内从而密封卡托推杆孔进行防水，针状推杆通过推动防水密封针顶动卡托推杆将卡托顶出壳体实现取SIM卡或装SIM卡，从而能够阻止水从壳体外进入壳体内侧，因此实现器件防水，避免器件短路或腐蚀导致机器损毁。
具体来讲，如图3和图4所示，PCB(Printed Circuit Board)，中文名称为印制电路板，又称印刷线路板，是重要的电子部件，是电子元器件的支撑体，是电子元器件电气连接的载体。由于它是采用电子印刷术制作的，故被称为“印刷”电路板。手机的PCB板25设置在壳体26内，SIM卡座21位于手机的PCB板25的上侧，而卡托22设置在该SIM卡座21内，用于盛放SIM卡。
与卡托22联动设置的卡托推杆23设置在SIM卡座21的一侧，推动卡托推杆23即可将卡托22顶出壳体26，从而实现将盛放在卡托22内的SIM卡的取出或装入。
金属壳手机的壳体26上开设有与卡托推杆23对应的卡托推杆孔27，卡托推杆孔27作为针状推杆推动卡托推杆将卡托顶出壳体实现取SIM卡或装SIM卡的通道，但由于卡托推杆孔的存在，所以水就能够轻易的从壳体外侧 28由这个卡托推杆孔27进入手机的壳体内侧29，导致器件短路或腐蚀导致机器损毁。
该金属壳手机卡托孔的防水结构通过设置防水密封针从而密封卡托推杆孔进行防水，其中，防水密封针24设置在该卡托推杆孔27内从而密封卡托推杆孔进行防水，针状推杆通过推动防水密封针顶动卡托推杆将卡托顶出壳体实现取SIM卡或装SIM卡，从而能够阻止水从壳体外进入壳体内侧，因此实现器件防水，避免器件短路或腐蚀导致机器损毁。
优选的，如图5所示，防水密封针24包括：密封针体241及套设在该密封针体外端的弹性密封圈242。密封针体241及弹性密封圈242为一体式结构或分体式结构。密封针体241为与卡托推杆孔27适配的圆柱状，其内端面作为卡托推杆23的推动面，与卡托推杆23接触；密封针体241的外端面作为针状推杆的接触面，从而通过针状推杆推动防水密封针顶动卡托推杆将卡托顶出壳体实现取SIM卡或装SIM卡。密封针体241的内端还设置有限位凸缘，防止防水密封针24从卡托推杆孔27内滑脱。密封针体241的外端周向开设有密封圈槽，用于套设弹性密封圈242。弹性密封圈242套设在该密封针体的外端，防水密封针24设置在该卡托推杆孔27内时，弹性密封圈242与卡托推杆孔27过盈配合，弹性密封圈242与卡托推杆孔27间产生持续的张力，从而能够阻止水从壳体外进入壳体内侧，而且在防水密封针的滑动过程中，这种张力持续存在，因此实现防水密封针在使用过程中长期防水。但推杆推动防水密封针，防水密封针滑动后退，顶动卡托推杆，卡托推杆就将卡托顶出壳体，实现取SIM卡或装SIM卡，完成后向壳体内压入SIM卡托，SIM卡托推杆复位，带动防水密封针复位，整个动作完成一个循环。
综上，该金属壳手机卡托孔的防水结构通过在卡托推杆外侧的卡托推杆孔内设置防水密封针从而密封卡托推杆孔进行防水，针状推杆通过推动防水密封针顶动卡托推杆将卡托顶出壳体实现取SIM卡或装SIM卡，从而能够阻止水从壳体外进入壳体内侧，因此实现器件防水，避免器件短路或腐蚀导致 机器损毁。
前述对本发明的具体示例性实施方案的描述是为了说明和例证的目的。这些描述并非想将本发明限定为所公开的精确形式，并且很显然，根据上述教导，可以进行很多改变和变化。对示例性实施例进行选择和描述的目的在于解释本发明的特定原理及其实际应用，从而使得本领域的技术人员能够实现并利用本发明的各种不同的示例性实施方案以及各种不同的选择和改变。本发明的范围意在由权利要求书及其等同形式所限定。
