Description

带时间延时机构支持商品装取的螺旋展示挂钩 技术领域
本实用新型涉及一种商品防盗展示挂钩，更具体的说，它涉及一种带时间延时机构支持商品装取的螺旋展示挂钩。
背景技术
目前零售环境中的防盗展示挂钩独立安装在各种规格的展示家具上，挂钩提供商品展示区域允许潜在客户观察或体验商品，但是由于设计的局限性，现有的防盗展示挂钩总存在安全性与便利性的冲突，若挂钩展示开口端是开放的，则在某些情况下贵重展示商品容易被商店扒手全部偷走；为了解决上述情况，部分挂钩支持展示开口端增加一个可拆卸的堵头来防止未经允许人员随意取卸展示商品，但是同时带来的不便是，取商品需要借助特定工具和商店工作人员的帮助，虽然降低了商品的盗窃率却增加了潜在客户体验和购买商品的难度，大大影响了客户的体验效果，同时工具一旦丢失就会为商品的展示带来不便。
实用新型内容
现有的防盗展示挂钩防护安全性与使用便利性间存在矛盾，其中某一方面性能的强化会导致另一方面性能的牺牲，为解决这一问题，本实用新型提供了一种既具备较高防盗性能，又能方便操作，兼顾安全性与便利性的带时间延时机构支持商品装取的螺旋展示挂钩。
本实用新型的技术方案是：带时间延时机构支持商品装取的螺旋 展示挂钩，包括支撑臂、螺旋管、时间延时机构和单向转动的手柄，时间延时机构上设有转矩输出轴，支撑臂包括上支撑杆和下支撑杆，上支撑杆一端与时间延时机构连接，上支撑杆另一端固设于一固定物上，下支撑杆一端与上支撑杆固连，下支撑杆另一端为自由端，螺旋管一端与转矩输出轴固连，上支撑杆和下支撑杆穿设于螺旋管内部且与螺旋管接触，手柄及转矩输出轴分别与时间延时机构传动连接。上支撑杆用来支撑整个螺旋展示挂钩，上支撑杆通过自身的安装结构与固定物连接，使螺旋展示挂钩固定在孔板或其它形式的展示家具上，下支撑杆用来挂置展示商品，螺旋管的匝圈间具有一定空隙，能容下至少一个展示商品，展示商品从下支撑杆自由端装入，然后沿指定方向旋动手柄使时间延时机构工作并通过转矩输出轴上输出转矩，带动螺旋管转动，螺旋管的转动又转化为螺纹传导，将展示商品沿下支撑杆往里推动，展示商品进入下支撑杆深处后，螺旋管匝圈封堵住展示商品的退出路径，依此方法可将多个展示商品逐个或逐组装入并逐个或逐组分隔在螺旋管匝圈间，挂在下支撑杆上，如要取出则使螺旋管反向旋转，按与装入过程相逆的过程逐个或逐组将展示商品推到下支撑杆自由端，取出过程需要花费一定时间，扒手如想盗取商品，不能很快得手，增加盗窃难度和风险，从而起到很好的防盗效果；而对于商家而言，工作人员只需简单地旋转手柄，无需专门的工具，就能取放商品，操作也比较方便，因此，本螺旋展示挂钩兼具安全性和便利性。
作为优选，时间延时机构包括外罩、螺旋齿轮、可与螺旋齿轮啮 合的装载齿轮、从动齿轮和可与从动齿轮啮合的取卸齿轮，手柄上设有手柄转轴，手柄转轴贯穿外罩两侧并转动连接在外罩上，同时手柄转轴还具有轴向滑动自由度，取卸齿轮和装载齿轮均同轴套设在手柄转轴上且与手柄转轴固连，同一时间内从动齿轮和装载齿轮二者中仅有一个与螺旋齿轮啮合，从动齿轮转动连接在外罩内的隔板上，转动连接于外罩上且与螺旋齿轮固连。手柄转轴可以轴向滑动，因此取卸齿轮和装载齿轮可以切换与螺旋齿轮传动连接状态，同一时间内螺旋齿轮只能与取卸齿轮和装载齿轮中之一建立传动连接，当取卸齿轮移动到与从动齿轮啮合的位置时，取卸齿轮、从动齿轮和螺旋齿轮形成传动路径，旋转手柄时螺旋齿轮经转矩输出轴带动螺旋管反转，将展示商品推到下支撑杆自由端以便取下；当装载齿轮到达与螺旋齿轮啮合的位置时，装载齿轮与螺旋齿轮建立传动连接，旋转手柄时螺旋齿轮经转矩输出轴带动螺旋管正转，将展示商品从下支撑杆自由端向固定端推动。
作为优选，外罩上滑动连接有一切换装置，切换装置位于手柄和取卸齿轮之间，切换装置上固连一卡板，卡板上设有与手柄转轴直径适配且可卡在手柄转轴周面的卡槽，卡板自由端设有弹簧，弹簧连接在外罩内的隔板上，手柄转轴上固设有限位凸环。自然状态下，切换装置在弹簧弹力作用下处于原点，此时限位凸环受卡槽阻挡，手柄转轴处于轴向的一侧极限位置上既不能进也不能退，而此时取卸齿轮与螺旋齿轮存在传动连接关系；按下切换装置后，卡槽与手柄转轴的限位凸环解除锁止状态，手柄转轴的轴向阻力消除，此时手柄可以轴向 移动，转为装载齿轮与螺旋齿轮啮合，设置切换装置可以方便、准确地找到装载齿轮、取卸齿轮各自与螺旋齿轮建立传动的位置。
作为优选，取卸齿轮的直径小于装载齿轮直径。这样以同样速率转动手柄时，螺旋管反转速率小于正转速率，最终体现为展示商品取下需要更长时间，而商品装入则相对更快，使得盗窃更为困难，而工作人员上货更为方便。
作为优选，本螺旋展示挂钩还包括螺旋管护罩，螺旋管护罩架设于螺旋管上方，螺旋管护罩与外罩。螺旋管护罩可防止展品顶端被破坏，同时又起到改善外观的作用，另外还可起到辅助支撑作用。
作为优选，时间延时机构和手柄之间设有标牌卡槽。标牌卡槽可用来挂放商品说明标牌。
本实用新型的有益效果是：
防盗性能好，操作方便。本实用新型用螺旋管匝圈将展示商品封闭挂置，取下商品需要耗费比装载商品更多的时间，增加盗窃难度和风险，从而起到很好的防盗效果；而对于商家而言，工作人员只需简单地旋转手柄，无需专门的工具，就能取放商品，操作也比较方便。

下面结合附图具体实施例对本实用新型作进一步说明。
实施例1：
如图1至图4所示，带时间延时机构支持商品装取的螺旋展示挂钩，包括支撑臂、螺旋管1、时间延时机构2和单向转动的手柄3，时间延时机构2上设有转矩输出轴6，转矩输出轴6转动中心处设有轴向通孔，支撑臂包括上支撑杆4和下支撑杆5，上支撑杆4一端穿入所述轴向通孔中，实现与转矩输出轴6转动中心转动连接，并固定于时间延时机构2内部，上支撑杆4另一端设有一对L形安装脚17，上支撑杆4通过安装脚17固定于一展示家具上，下支撑杆5一端与上支撑杆4固连，下支撑杆5另一端为自由端，上支撑杆4和下支撑杆5的固定端设有一安装罩盖19，将上支撑杆4和下支撑杆5的固定端遮盖住。螺旋管1一端与转矩输出轴6固连，上支撑杆4和下支撑杆5穿设于螺旋管1内部且与螺旋管1接触。时间延时机构2包括外罩7、螺旋齿轮8、可与螺旋齿轮8啮合的装载齿轮10、从动齿轮11和可与从动齿轮11啮合的取卸齿轮9，手柄3上设有手柄转轴12，手柄转轴12贯穿外罩7两侧并转动连接在外罩7上，同时手柄转轴12还具有轴向滑动自由度，取卸齿轮9和装载齿轮10均同轴套设在手柄转轴12上且与手柄转轴12键连接，而转矩输出轴6位于外罩7 之外，与设置在外罩7上的圆孔转动穿连且与螺旋齿轮8一体成型，从而实现手柄3及转矩输出轴6分别与时间延时机构2传动连接。外罩7下方设有旋转止销与装载齿轮10配合实现手柄3单向旋转，防止反转。上支撑杆4与安装脚固定端相对的另一端从转矩输出轴6及螺旋齿轮8中心穿入后一直延伸到外罩7以内，外罩7上设有一螺钉穿孔，上支撑杆4上与安装脚固定端相对的一端端部周面上设有一凹孔，通过一螺钉穿过螺钉穿孔，再螺纹连接到上支撑杆4的凹孔中，就可将时间延时机构2与上支撑杆4固连起来。从动齿轮11和装载齿轮10的厚度均为螺旋齿轮8厚度的一半，取卸齿轮9和装载齿轮10的间距为螺旋齿轮8厚度的一半，从动齿轮11转动连接在外罩7内的隔板上，从动齿轮11偏置于螺旋齿轮8一侧并始终与螺旋齿轮8的半边啮合。外罩7上滑动连接有一切换装置13，切换装置13位于手柄3和取卸齿轮9之间，切换装置13上固连一卡板14，卡板14上设有与手柄转轴12直径适配且可卡在手柄转轴12周面的卡槽，卡板14自由端设有弹簧15，弹簧15连接在外罩7内的隔板上，手柄转轴12上固设有限位凸环。取卸齿轮9的直径小于装载齿轮10直径，这样使得商品从下支撑杆5装载的速率快于从下支撑杆5上取卸商品的速率。本展示挂钩还包括一透明的螺旋管护罩16，螺旋管护罩16架设于螺旋管1上方，螺旋管护罩16两端分别与外罩7和安装罩盖19卡接。时间延时机构2和手柄3之间设有标牌卡槽，用来挂放写有商品说明的标牌18。
时间延时机构2用于增加取卸展示商品所需的时间量，同时允许 挂钩上剩余的展示商品继续展示在本螺旋展示挂钩上。安装本螺旋展示挂钩时，需要先用螺丝刀拧松外罩7上的螺钉，取下时间延时机构2和螺旋管1，此时可将安装罩盖19沿所述支撑臂推到底，将安装脚17向上微翘穿过展示家具上对应的安装孔，在重力作用下本螺旋展示挂钩将整体固定在展示家具上，而后螺旋管1和时间延时机构2按上述取下顺序重新安装回所述支撑臂上，拧紧所述螺钉，而后将螺旋管护罩16卡在安装罩盖19和时间延时机构2的外罩7之间，此时本螺旋展示挂钩固定在展示家具上。本螺旋展示挂钩设置的默认状态为商品的取卸状态，若需切换至商品装载状态则需依靠切换装置13。使用过程中若需要将商品悬挂至本螺旋展示挂钩上，需将商品先放置于下支撑杆5自由端，按住切换装置13，推动卡板14移位让出通道，卡板14上的卡槽结构与限位凸环解除锁止状态，结构上允许其通过，此时手柄3可以无障碍地外拉到极限，然后放开切换装置13，卡板14回弹，卡住限位凸环一侧防止其回缩，此时装载齿轮10与螺旋齿轮8啮合，旋转手柄3，带动螺旋管1，螺旋管1随手柄3的旋转而改变下支撑杆5上展示商品的距离，上述螺旋结构3螺距足够容纳展示商品的包装厚度同时防止小偷暴力偷取展示商品，展示商品依靠螺纹传导沿下支撑杆5往远离自由端方向移动，此后重复上述描述逐个放置展示商品在自由端12理论上是单个商品，不排除特殊情况下一起装载多个极小极薄的展示商品并重复沿指定方向旋转手柄直至将全部展示商品悬挂在下支撑杆5上。装载完成后如需将装载状态切换至取卸状态，操作如下：再次按下切换装置13，弹簧压缩，上述卡板14上的卡槽与限位凸环解 除锁止状态，推动卡板14移位让出通道，向里推动手柄3至极限，放开切换装置13，卡板14回弹，卡住限位凸环另一侧，此时取卸齿轮9移动到与从动齿轮11啮合的位置，且手柄3无法再轴向移动，取卸齿轮9、从动齿轮11和螺旋齿轮8形成传动路径，旋转手柄3时螺旋齿轮8经转矩输出轴带动螺旋管1反转，将展示商品推到下支撑杆5自由端以便取下。
实施例2：
上支撑杆4一端与转矩输出轴6转动中心转动连接，上支撑杆4另一端设有膨胀螺栓，上支撑杆4通过膨胀螺栓固定在墙壁上。其余同实施例1。
