Description
本发明涉及一种防盗标签，广泛用于商店或超市商品的防盗。
防盗标签是一种被广泛应用于商品市场上的防盗产品，固定在待售商品上，当待售商品未经收银员处理、取下防盗标签时，该商品在经过商场出口时会发出报警信号，提醒商场保安人员。但是一般防盗标签经过几年使用后，安全性会降低，因此，针对防盗标签的产品不断推陈出新。
申请号201810579544.6公开了一种防盗标签组件，其包括：防盗标签及用于套设于防盗产品上的套体；所述防盗标签固定于所述套体上。还公开了一种带有防盗标签组件的防盗产品。能够有效地将防盗标签固定于不适合粘贴及钉扣的商品上。
申请号201711054179.9提供了一种针锁式防盗标签及其开锁器，所述针锁式防盗标签，包括壳体，所述壳体中设置用于锁住防盗针的由磁性开锁器开锁的锁芯，所述锁芯设置有用于锁住防盗针的锁件；其特征在于所述锁芯设置有与旋转的磁场配合的锁件支撑装置，所述锁件支撑装置能够在旋转的磁场的作用下将旋转运动转化为升降运动而使其上的多个锁件进入锁定位和解锁。本发明采用新方式开锁，使市面现有开锁器无法对标签实现开锁，提高商品防盗能力。
实用新型专利号201720795856.1涉及一种防盗装置。目的是提供一种改进结构的防盗标签，该防盗标签应具有两种开锁结构，并且结构简单、使用便利、性能可靠稳定。技术方案是：双开锁防盗标签，包括带有钉帽的钉杆以及带有钢球式锁芯的标签座；其特征在于：所述钢球式锁芯与标签座的壁部之间还定位一可竖直滑动的活动块，活动块的一端置于钢球式锁芯的顶端，活动块的受压端则可竖直滑动地定位在钢球式锁芯外侧的滑道中；所述标签座内又设置一开锁轨道，开锁轨道的一端延伸至所述活动块的受压端，开锁轨道的另一端连通位于标签座表面的开锁口；另有一与开锁口横截面形状相配合的开锁杆。
本申请人在其发明专利号ZL20091004745.43中公开了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***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，磁力开锁器与锁紧机构对应，并由磁力开锁器打开锁紧机构，所述的锁紧机构上设有磁力开关装置，磁力开关装置内的磁块被开锁器内的磁铁推动向远离磁铁的方向移动，磁块推动锁紧机构打开。其通过 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形式。
另外，本申请人对上述防盗结构进行了改进，发明的专利号201320522186.8一种防盗标签，包括壳体和防盗钉锁紧机构，防盗钉***外壳内并由锁紧机构锁紧定位，通过磁力开锁器解锁，该锁紧机构自上而下依序包括：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，在所述的锁紧珠固定座下方套设一限位套件，该限位套件被底座限位，该限位套件内设通孔，外周设有一对径向结构对称上方为平面且向下收拢的翅形倒斜面，所述的通孔上方套入锁紧珠固定座底部的伸出部，弹簧穿设在所述的通孔内，所述的限位套件底面支撑有至少一只钢球；所述钢球放在底座的斜面的最低处，在磁力作用下可沿斜面滚动，而失去对限位套件的支撑，实现安全解锁。

发明内容
针对上述缺陷，本发明目的在于提供一种防盗标签，通过对锁紧珠抵顶锁紧机构的改进，只有通过磁力开锁器才能使锁紧珠移开，达到锁紧机构安全解锁。
本发明目的通过下述技术方案实现：一种防盗标签，包括由上盖和底座构成的壳体，上盖和底座之间设防盗钉锁紧机构，防盗钉自上盖***外壳中并由锁紧机构锁紧定位，磁力开锁器与锁紧机构对应，通过磁力开锁器打开锁紧机构，该锁紧机构自上而下依序包括：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，其中：
所述的底座中心位置上有一长开槽，长开槽的中间为弹簧座，在弹簧座的二侧上端对称设有与底座中心线平行的卡口；
所述的上盖与长开槽位置对应设有凸筋，并在卡口对应位置设有股片；
所述的弹簧放在弹簧座上，下部抵顶底座的底部，上部盖一弹簧盖，一对钢球分设弹簧座的二侧；
一对结构相同的摇摆件上端设有摆轴，在弹簧侧上端有伸出的凸爪，与凸爪同侧的下方为敞口的圆窝，锁紧珠在圆窝內，当摇摆件上端摆轴安装在卡口内，下端四周从外向内包覆钢球，所述的凸爪上端抵顶锁紧珠固定座的底部，下端抵顶弹簧盖，由上盖的股片抵住摆轴；
开锁时，底座受磁推力开锁器作用，钢球在磁推力作用下沿长开槽向底座二侧外移，推动二个摇摆件以摆轴为轴心向外摆动，至摇摆件凸爪上端失去了对锁 紧珠固定座的抵顶，同时摇摆件凸爪的下端下压弹簧盖和弹簧，使弹簧失去了对锁紧珠固定座的抵顶，锁紧珠固定座中的锁紧珠受开锁器磁性吸力下移，解锁。
只有当磁推力开锁器的磁推力大于摇摆件对弹簧、锁紧珠固定座的抵顶力及钢球自重之和时，钢球带动摇摆件摆动到从摇摆件脱离，则锁紧珠固定座失去抵顶力下移，解锁。
为方便生产加工，减少对模具精度的要求，在上述方案基础上，所述的长槽为分体式内壳，可拆卸的安装在底座的底部，中间为弹簧座，弹簧座二侧上方对称设有与中心线平行的卡口。
在上述方案基础上，所述的底座为开口向上的圆窝形，所述的弹簧座设在圆窝形的最低点，使摇摆件的凸爪上端抵顶锁紧珠固定座的底部，下端贴紧弹簧盖，使摇摆件凸爪受弹簧力作用被托起，所述的钢球在摇摆件凸爪受弹簧托起的作用下紧靠弹簧两侧，防盗钉被锁紧。
或者，所述的钢球在自身重力作用下靠近弹簧座，使摇摆件的凸爪上端抵顶锁紧珠固定座在底部，下端压紧弹簧盖，防盗钉被锁紧。
本发明所述的磁力开锁器由上、下磁环叠加构成，其中，所述的下磁环的内外径小于上磁环的内外径，但下磁环的高度大于上磁环的高度。
本发明的原理是：由一对摇摆件抵顶锁紧机构，使锁紧机构的解锁过程除必须克服弹簧力外，还要使钢球移动力来推动摇摆件使其向外摆动，因此需要使用与发明匹配的磁力开锁器方能移动一对锁紧珠，在磁推力作用下，解除了弹簧力和摇摆件的夹紧力，解锁。有效防止使用多块磁铁自行解锁或大磁力下的钢球移位的情况。使用更安全、可靠。
本发明的有益效果是：防盗标签结构简单，容易制造，只采用简单结构的磁铁组合不能打开锁紧机构，只有通过与本发明匹配的磁力开锁器才能使锁紧珠移开，达到锁紧机构安全解锁。

如图9本发明分体内壳结构示意图所示，其他与实施例1相同，只是为了减少对模具精度要求，本实施例将所述的长槽为分体式内壳8’，可拆卸的安装在底座的底部，中间为弹簧座81’，弹簧座81’二侧上方对称设有与中心线平行的左、右卡口82’、83’。
Claims (4)
- 一种防盗标签，包括由上盖和底座构成的壳体，上盖和底座之间设防盗钉锁紧机构，防盗钉自上盖***外壳中并由锁紧机构锁紧定位，磁力开锁器与锁紧机构对应，通过磁力开锁器打开锁紧机构，该锁紧机构自上而下依序包括：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，其特征在于：所述的底座中心位置上有一长开槽，长开槽的中间为弹簧座，在弹簧座的二侧上端对称设有与底座中心线平行的卡口；所述的上盖与长开槽位置对应设有凸筋，并在卡口对应位置设有股片；所述的弹簧放在弹簧座上，下部抵顶底座的底部，上部盖一弹簧盖，一对钢球分设弹簧座的二侧；一对结构相同的摇摆件，上端设有摆轴，在弹簧侧上端有伸出的凸爪，与凸爪同侧的下方为敞口的圆窝，钢球在圆窝內，当摇摆件上端摆轴安装在卡口内，下端四周包覆钢球，所述的凸爪上端抵顶锁紧珠固定座的底部，下端抵顶弹簧盖，由上盖的股片抵住摆轴；开锁时，底座受磁推力开锁器作用，钢球在磁推力作用下沿长开槽向底座二侧外移，推动二个摇摆件以摆轴为轴心向外摆动，至摇摆件凸爪上端失去了对锁紧珠固定座的抵顶，同时摇摆件凸爪的下端下压弹簧盖和弹簧，使弹簧失去了对锁紧珠固定座的抵顶，锁紧珠固定座中的锁紧珠受开锁器磁性吸力下移，解锁。
- 根据权利要求1所述的防盗标签，其特征在于，所述的长槽为分体式内壳，可拆卸的安装在底座的底部，中间为弹簧座，弹簧座二侧上方对称设有与中心线平行的卡口。
- 根据权利要求1或2所述的防盗标签，其特征在于，所述的底座为开口向上的圆窝形，所述的弹簧座设在圆窝形的最低点，使摇摆件的凸爪上端抵顶锁紧珠固定座的底部，下端贴紧弹簧盖，使摇摆件凸爪受弹簧力作用被托起，所述的钢球在摇摆件凸爪受弹簧托起的作用下紧靠弹簧两侧，防盗钉被锁紧。
- 根据权利要求1所述的防盗标签，其特征在于，所述的磁力开锁器由上、下磁环叠加构成，其中，所述的下磁环的内外径小于上磁环的内外径，但下磁环的高度大于上磁环的高度。
