Description

磁推力防盗标签 技术领域
本实用新型涉及一种磁推力防盗标签， 广泛用于商店或超市商品的防盗。 背景技术
防盗标签是一种被广泛应用于商品市场上的防盗产品， 主要包括锁紧式防 盗标签， 采用特定的机械结构制成锁紧机构， 锁紧防盗钉， 使其固定于商品上， 只能通过相应的解锁工具才能打开； 报警式防盗标签， 通过在标签内设置电子或 其他报警元件，发出报警信号；综合式防盗标签，兼具上述两种防盗标签的特点。
经过广泛使用， 传统的磁性防盗标签已缺乏了绝对的安全防盗功能， 容易 被任意一块磁石打开。 本实用新型的申请人在其实用新型专利号 ZL200620045680. X 中公开了一种安全方便的防盗标签， 在传统的锁紧机构的基 础上进一步增设横向卡位装置，使得防盗标签必须在纵向和横向双向作用力条件 下， 即在原有底部装设有磁块的启钉器上增设横向磁力的作用， 先打开锁紧机构 上的卡固机构后，才可以利用启钉器底部的磁块打开锁紧机构，使防盗标签开启， 极大地增强了安全性。
但是这种从两个方向上双重解锁的结构形式略显复杂， 且任何人可以携带 数枚磁块先用一磁块打开横向卡固机构， 再用一块开启锁紧机构， 所以全部采用 磁性作用开启防盗钉锁紧机构还是没有绝对安全。
发明内容
本实用新型所要解决的技术问题在于提供一种新型结构的磁推力防盗标签， 采用不同以往的磁性推力， 而非磁性吸力， 结合锁紧机构上的磁力开关装置完成 对锁紧机构的打开。 本实用新型解决上述技术问题采取的技术方案是：一种磁推力防盗标签， 包 括由上盖和底座构成的外壳，上盖与底座之间设有线圈报警器、防盗钉锁紧机构， 防盗钉自上盖插入外壳中并由锁紧机构定位， 其中， 锁紧机构包括： 截面为梯形 的锁紧珠帽、与锁紧珠帽内腔匹配的锁紧珠固定座、不少于三颗的锁紧珠和抵顶 锁紧珠固定座的弹簧装置，锁紧机构与磁力开锁器对应并由其打开， 所述的锁紧 机构上设有磁力开关装置，磁力开关装置内设有推动锁紧机构打开的磁块， 所述 磁块被开锁器内的磁铁推动向远离磁铁的方向移动。
本实用新型的设计原理是：利用磁力开关装置内的磁块与相应开锁器内的磁 铁间的相互作用力， 推动磁块的移动。在锁紧状态下， 弹簧机构抵顶锁紧珠固定 座， 由于锁紧珠固定座与截面为梯形锁紧珠帽内腔匹配， 锁紧珠帽径向压紧设在 锁紧珠固定座通孔内的锁紧珠， 从而将穿过锁紧珠固定座的防盗钉锁紧固定。 当 磁块推动锁紧机构时， 锁紧珠固定座被向下推压， 脱离锁紧珠帽， 锁紧珠不再受 到锁紧珠帽的径向压力因而释放锁紧钉。在开锁器离开防盗标签后， 在弹簧机构 的抵顶下， 锁紧珠固定座重新进入锁紧珠帽内， 将锁紧钉重新固定。
在上述方案的基础上，提供一种推动锁紧珠固定座的磁力开关装置， 所述的 磁力开关装由设在外壳内的至少一块磁块以及由磁块推动的拨动块组成，锁紧珠 固定座上设有下压部， 拨动块设在下压部上。
在上述方案的基础上，提供一种具体的防盗标签结构， 所述的拨动块由横向 的环型臂和自环型臂向下伸出的直臂构成，环型臂套设在固定座下压部上， 其上 设有一对由外壳旋转定位的支点； 磁块设在直臂内侧的限位部下方， 磁块的下端 设在底座的卡位部处； 磁块为受推力沿直臂内侧上滑的磁块， 磁块脱离卡位部并 向外横动推抵拨动块绕支点转动下压固定座， 锁紧机构打开。
在上述方案的基础上，提供另一种具体的防盗标签内部结构， 所述的拨动块 由横向的环型臂和自环型臂向下伸出的直臂构成， 环型臂套设在固定座下压部 上， 其上设有由外壳旋转定位的支点， 直臂设在磁块的上方； 磁块为受推力沿底 座上滑的磁块， 磁块推动拨动块绕支点转动下压固定座， 锁紧机构打开。
在上述方案的基础上，提供第三种具体的防盗标签内部结构， 所述的拨动块 为横向的环型件，环型件套设在固定座下压部上， 其上设有由外壳滑槽定位的凸 部， 底部设有斜面； 磁块的上方设有一推块， 推块抵顶环形件； 磁块为沿底座内 腔上滑的磁块， 磁块上推推块， 推块推抵拨动块横向滑动， 其斜面下压固定座， 锁紧机构打开。
在上述方案的基础上，提供第四种具体的防盗标签内部结构， 所述的拨动块 由螺旋套和一对旋转臂构成， 螺旋套套在固定座外侧， 底部设有带缺口的斜面， 缺口设在固定座下压部上， 一对旋转臂由外壳支撑定位， 一旋转臂设在弹簧处， 另一旋转臂设在磁块处； 磁块为沿底座内腔上滑， 顶端可以设计成斜面， 磁块斜 面向上推动旋转臂旋转， 螺旋套的斜面下压固定座， 锁紧机构打开； 反之， 弹簧 推动旋转臂反向旋转， 螺旋套复位， 锁紧机构锁紧。
所述旋转套的斜面设有至少一个。
本实用新型旨在提供一种不同以往的磁力方向从而打开锁紧机构，具体推压 锁紧珠固定座的结构还可以有其他众多形式。
在上述方案的基础上， 所述的磁块在外壳内斜向设置并由磁铁斜向上推动。 在上述方案的基础上，所述锁紧珠固定座的下压部为凸块或凸环。 凸块一般 设有对称的一对， 以保证向下的压力均衡。
针对上述的防盗标签的磁环型开锁器，所述的开锁器为带内孔的磁块， 或为 由至少两块带内孔的磁块叠置而成的磁块。
本实用新型的有益效果是：
本实用新型提供了一种新型的解锁形式， 通过磁性推力而非传统的磁性吸 力打开锁紧机构， 为常用的防盗标签提供了一种简单易行又安全可靠的新形式。 附图说明 图 1为本实用新型实施例 1的剖面结构示意图。
