Description

一种保管箱或保险箱用电磁铁开启装置 技术领域
本发明涉及一种保管箱或保险箱用电子锁，尤其涉及一种保管箱或保险箱用电磁铁开启装置。
背景技术
保管(险)箱上的电子锁通常包括密钥读取装置、电磁铁开启装置、锁舌组件。密钥读取装置通常是密码读取装置或指纹采集装置，电磁铁开启装置主要是一个由电磁线圈驱动的电磁铁，电磁铁与密钥读取装置相连且由其控制，当电磁铁开启装置在未通电的情况下，电磁铁外伸，挡住锁舌组件中的锁舌拉板，防止锁舌回缩，当密钥读取装置读取密钥并验证后，向电磁铁开启装置通电，使电磁铁回缩，此时转动锁舌组件中开门旋钮，可使锁舌拉板带动锁舌回缩，将门打开。
一般电磁铁开启装置中，由电磁铁的电磁线圈驱动动铁芯，并用弹簧回弹结构来实现锁的开启与关闭，由于电磁铁的磁性吸引力有限而且必须大于弹簧的弹力，因此弹簧的弹力不能过大，而较小的弹力使得在关闭状态时，遇到震动、敲打、冲击等状况，电磁铁中的动铁芯受外力惯性影响，压缩弹簧，失去对锁舌拉板的限位作用，从而打开保管(险)箱，大大影响到保管(险)箱的稳定性和安全性。
发明内容
本发明目的是提供一种保管箱或保险箱用电磁铁开启装置，通过结构改良，防止电磁铁受外力作用下误开启操作，提高保管(险)箱使用的稳定性和安全性。
为达到上述目的，本发明采用的技术方案是：一种保管箱或保险箱用电磁铁开启装置，包括壳体，壳体内设有定铁芯、动铁芯、电磁线圈、拨片以及闭合弹簧，所述动铁芯底端与所述定铁芯配合，顶端套设有轴套，该轴套经壳体上的通孔延伸至壳体的外侧，所述壳体内还设有一震动感应机构，该震动感应机构包括感应块及平衡 弹簧，所述感应块上设有阻挡端及平衡端，两者分别位于所述动铁芯的两侧，所述平衡弹簧设置于所述平衡端底部与所述壳体之间，所述阻挡端底部经转轴转动连接于所述壳体上，当所述感应块通过所述转轴转动压缩所述平衡弹簧时，所述阻挡端抵于所述轴套底面上。
上述技术方案中，所述阻挡端侧的所述壳体上设有挡块，所述挡块的前端抵于所述阻挡端上。
上述技术方案中，所述感应块上设有U型槽，所述动铁芯位于该U型槽内，并与两侧槽壁之间设有空隙，所述阻挡端及平衡端分别位于所述U型槽的两侧。
上述技术方案中，所述平衡端底部开设有安装孔，所述平衡弹簧一端设置于该安装孔内。
上述技术方案中，所述壳体内腔中部设有分隔挡板，所述震动感应机构位于所述分隔挡板的上面，所述电磁线圈及定铁芯位于所述分隔挡板的下面。
进一步的技术方案是，所述平衡弹簧的底部固定于所述分隔挡板上。
由于上述技术方案运用，本发明与现有技术相比具有下列优点：
1.本发明中增加了震动感应机构，由一侧经转轴转动连接于壳体上的感应块及位于转轴一侧的平衡弹簧构成，当保管(险)箱遇到震动、敲打、冲击等状况时，感应块在惯性力的作用下平衡端压缩平衡弹簧，感应块绕转轴逆时针旋转，从而阻挡端上翘而抵住动铁芯上的轴套，防止其随惯性力下移，保证保管(险)箱不被误打开，提高使用稳定性和安全性；
2.阻挡端侧的壳体上设有挡块，防止感应块反向旋转，确保感应块的运作稳定性和可靠性。

具体实施方式
下面结合附图及实施例对本发明作进一步描述：
实施例一：参见图1～6所示，一种保管箱或保险箱用电磁铁开启装置，包括壳体1，壳体1内设有定铁芯2、动铁芯3、电磁线圈4、拨片5、闭合弹簧6及震动感应机构7，所述动铁芯3底端与所述定铁芯2配合，顶端套设有轴套8，该轴套8经壳体1上的通孔延伸至壳体1的外侧，所述震动感应机构7包括感应块及平衡弹簧9，所述感应块上设有阻挡端10及平衡端11，两者分别位于所述动铁芯3的两侧，所述平衡弹簧9设置于所述平衡端11底部与所述壳体1之间，所述阻挡端10底部经转轴12转动连接于所述壳体1上，当所述感应块通过所述转轴12转动压缩所述平衡弹簧9时，所述阻挡端10抵于所述轴套8底面上。
如图3所示，所述壳体1内腔中部设有分隔挡板14，所述震动感应机构7位于所述分隔挡板14的上面，所述电磁线圈4及定铁芯2位于所述分隔挡板14的下面。所述平衡端11底部开设有安装孔15，所述平衡弹簧9一端设置于该安装孔15内，另一端固定于所述分隔挡板14上。所述阻挡端10侧(右侧)的所述壳体1上设有挡块16，所述挡块16的前端抵于所述阻挡端10上，用于防止 感应块在惯性力下反向(顺时针)转动，确保感应块的正常运作。
如图4所示，所述感应块上设有U型槽17，呈马蹄形，所述动铁芯3位于该U型槽17内，贯穿感应块，并与两侧槽壁之间设有空隙20，所述阻挡端10及平衡端11分别位于所述U型槽17的两侧。所述空隙20的大小需要与感应块的转动角度配合，使得感应块在受到惯性力逆时针转动时，阻挡端10可上翘抵于轴套8上(如图5所示)。
在使用时，本实施例安装于保险箱门18背后，如图6所示，电磁铁与机械结构的锁舌组件13配合动作，在锁合状态下，动铁芯3上的轴套8伸出于壳体1外部，防止锁舌被打开。当密钥读取装置19读取密钥并验证后，向电磁铁开启装置通电。电磁线圈4通电后，动铁芯3与定铁芯2之间因相互相吸的磁力作用，带动轴套8、动铁芯3、拨片5下移，压缩闭合弹簧6，使电磁铁处于开锁状态，锁舌组件13便可以打开。当电磁铁在闭合状态下受外力震动、敲打、冲击等情况时，轴套8、动铁芯3、拨片5因为惯性力的作用下，向闭合弹簧6方向移动，同时感应块在惯性力的作用下压缩平衡弹簧9，感应块逆时针旋转，阻挡端10刚好挡住轴套8、动铁芯3、拨片5的移动，这样就不会使电磁铁因为受震动、敲打、冲击等情况下的惯性作用而打开，提高了保险箱的安全性及稳定性。
