Description

挂钩 技术领域
本发明涉及一种物品固定装置，尤其涉及一种用粘帖方式来固定的挂钩。
背景技术
在日常工作及家庭生活中，到处可见一些固定物品的装置，其中最为常用的就是挂钩。挂钩主要有两种不同的类型：
一种是胶粘型，其利用橡胶或塑料粘性固定于墙壁等处，典型的例子如贴纸式挂钩，其包括一贴纸和附着于贴纸上的钩体，贴纸具有较大面积，将该大面积的贴纸贴于墙壁，造成空气密封效果，钩体悬挂物体时，贴纸受力与墙壁分离，在其间形成真空，即可利用大气压让钩体承载一定重量的物体。这种贴纸式挂钩只能使用一次，还不能移动，否则粘性减弱，并且使用后时会在墙壁上残留胶粘剂。
另一种是真空吸附型挂钩，其通常利用一吸盘吸附于墙面上，以达到固定支撑物体的效果。然而这种吸盘的承重较小，一般只能用于光滑平整的墙面，，不适合应用于普通墙面或木质墙面等粗糙的表面。而且，吸盘材料在长期受力后容易出现疲劳和老化，降低使用寿命。
 技术问题
有鉴于此，提供一种固定牢靠、应用多样性的胶粘式挂钩。
技术解决方案
一种挂钩，其包括粘合体和附着于粘合体上的钩体，所述粘合体包括基层和胶层，所述钩体和胶层分别附着于基层相对两表面上。
有益效果
上述挂钩在钩体和胶层之间具有一基层，避免钩体直接粘附于胶层，在使用时，物体不至于对胶层形成直接牵拉，以增强胶层的使用寿命，加大粘附强度，使得挂钩能牢固地支撑住物体。而且，通过夹设基层，可增强挂钩的韧性，不易产生变形，抗拉、抗老化性好，并且在基层上易于印刷各种所需图案、色彩或纹理，具有应用多样性、实用性强的特点。
附图说明
以下结合附图描述本实用新型的实施例，其中：
图1为本发明第一实施例的挂钩立体结构示意图；
图2为本发明第一实施例的挂钩侧面结构示意图；
图3为本发明第二实施例的挂钩立体结构示意图；
图4为本发明第二实施例的挂钩的钩部分解结构示意图；
图5为本发明第三实施例的挂钩立体结构示意图；
图6为本发明第三实施例的挂钩的钩部分解结构示意图。
 本发明的实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
请参阅图1和2，为本发明第一实施例的挂钩10，其包括粘合体12和附着于粘合体12上的钩体16，粘合体12包括基层13和胶层14，钩体16和胶层14分别附着于基层13的相对两表面上。粘合体12的面积大于其与钩体16接触面的面积。
其中，基层13可以包括聚丙烯薄膜、聚碳酸酯薄膜、聚乙烯薄膜、聚对苯二甲酸乙二酯薄膜、布料、皮革或合成纸等。胶层14自然有柔软性能，这样就使得挂钩10可以悬挂于曲面、粗糙或凹凸表面，甚至是很粗糙或凹凸起伏程度很高的表面。当然，可以理解的是，基层14也可以是有一定硬度或韧性的薄膜或薄片，例如金属薄片。实际应用中，基层14可包括聚丙烯薄膜、聚碳酸酯薄膜、聚乙烯薄膜、聚对苯二甲酸乙二酯薄膜、布料、皮革、金属薄片或合成纸中的至少一种。
胶层14可以是热塑性弹性体，优选为苯乙烯系热塑性弹性体，例如TPE (ThermoPlastic Elastomer)、TPR (Thermo plastic rubber)或苯乙烯-丁二烯-苯乙烯嵌段共聚物 (Styrene-butadiene styrene，简称为SBS)材质等。优选地，胶层包括按重量份数计的下列成分：100份的苯乙烯-乙烯-丁二烯-苯乙烯(Styrene-ethylene-butadiene styrene，简称为SEBS)嵌段共聚物，100-300份的氢化环烷油，100-300份的白油， 0-10份的石油增粘树脂，1-5份的聚丙烯树脂，2-10份的助剂。其中，SEBS可以由美国Kratn公司提供的G系列、D系列和中国岳阳巴陵华兴石化有限公司提供的YH系列。氢化环烷油的重量份数优选为150-300份，更优选为200-280份， 氢化环烷油在此作为填充油，可以是由中国克拉玛依石化公司（Petrochina Karamay Petrochemical Company）的KNH系列和NK系列环烷基油，例如，可以是以环烷基原油的常压馏分为原料，经加氢、糠西醛、白土精制再加入抗氧剂调制而成。白油和环烷基油协同作用，白油的重量份数优选为150-300份，更优选为200-280份。石油增粘树脂可以是例如C9石油树脂、C5石油树脂、C5／C9共聚石油树脂、双环戊二稀（DCPD）石油树脂四大系列产品，主要以C5馏分、C9馏分为主要原料制备。石油增粘树脂的重量份数优选为1-10份，更佳为3-8份。加入聚丙烯树脂可以提高产品的模量和硬度。 助剂包括但不限于增塑剂（如石蜡或PE低聚物）、抗氧剂（如碳酸钙或硅微粉）、光稳定剂和紫外线稳定剂（如UV-P和UV-320）等，助剂的重量份数优选为4-8份，分别用来增塑、抗氧化或老化、提高光照稳定性和紫外光照的稳定性等。其中，填充油的份量关联胶层材质的硬度和表面粘性，从而不需要含有太多增粘树脂，所以在挂钩的使用过程中可以很方便地清洗掉粘附在胶层表面的灰尘，从而不会影响产品的品质。
通过上述配方的胶层14，可表现出极好的粘接强度和硬度，符合挂钩的性能需求，例如，能牢固地粘附在墙壁等上，并且能够循环使用，使用寿命长，撕开后能继续使用，粘性基本不变。
优选地，胶层为表面粘接强度在0.1-0.6N/cm，胶层的厚度为0.1-2.0毫米，胶层的硬度为邵氏A硬度0-20度。胶层14可通过热熔射出或涂布方法与基层13结合在一起，基层13和胶层14在结合前可以先进行表面处理，还可制作各种图案、色彩或纹理。这种热塑性弹性体胶层14可以重复使用多次而不会损坏其粘性，因为其并非利用粘合剂，而是利用热塑性弹性体材料自身固有的粘附力，使其粘附于墙面等处，而且在移动后胶层14仍保留其粘附力，经过长时间使用并多次移动重复使用后，其粘附力基本不会减弱，从而延长挂钩使用寿命。移动后也不会在原来粘附处残留粘胶，因而给使用者提供极大的便利。此外，这种热塑性弹性体便于清洗粘附于其表面的灰尘、杂质等，可轻易地清扫或去除这些物质，因为，这些物质只是吸附在热塑性弹性体表面，而不是像现有技术中的粘胶那样被粘住。
如图2所示，胶层14的外表面还覆盖有一个保护膜18。保护膜18包括塑料薄膜层或纸层以及离型层，离型层附着于塑料薄膜层或纸层与胶层14接触的表面，以方便保护膜18从胶层14分离。保护膜18可采用聚对苯二甲酸乙二酯（Poly(ethylene terephthalate)，PET）、聚丙烯（Polypropylene，PP）、聚乙烯（Polyethylene, PE）、各种纸类等。该保护膜18用于减少人工作业对产品造成的污染，保障产品的良好品质，例如可在制造的包装与运输或不使用时保护胶层14，在使用时去除，以便用胶层14粘性固定物品。
钩体16包括固定部17和钩部19，固定部17附着于基层13上，例如，通过粘胶剂将固定部17粘合于基层13上。钩体16的材质可选用塑胶、合成塑胶、五金、木质、陶瓷、橡胶中的一种或其任意组合。一般地，不同的钩体16材质与不同的基层13粘合需选用不同的粘胶材料。固定部17附着于基层13的表面为平整的表面，以增强它们之间的粘附力。固定部17和钩部19为一体结构或分体结构，图1和2中的挂钩10即采用一体结构形式。当采用一体结构形式时，固定部17和钩部19为一体成型的整体结构。当采用分体结构形式时，固定部17和钩部19可通过各种可拆卸结构相互连接。这种可拆卸连接方式的好处在于，一方面当钩部19用旧或损坏时，可以方便更换钩部19；另一方面，可取下钩部19将其清洗。另外，还可将钩部19取下后，直接勾住物体，再将勾有物体的钩部19安装回固定部17，这样有利于悬挂一些不便于直接悬挂于在墙面的挂钩10的物体。
请参阅图3和图4，显示本发明第二实施例的挂钩20，此实施例的挂钩20基本类似于第一实施例中的挂钩10，主要不同之处在于固定部17和钩部19的结合方式，其中在图3、4中与图1和2中相同的元件采用相同的标号，在此不再赘述。
在第二实施例的挂钩20中，固定部17和钩部19是采用卡扣结构，如图所示，该卡扣结构包括分别设置于固定部17上的卡槽21和钩部19上的卡榫22。图示中的卡槽21为两个，分别设于一平躺设于固定部17上的柱体的两端，钩部19为一个回弹性卡夹，具有两个相对的卡夹末端，分别为一个卡榫22。在使用时，卡榫22嵌入于卡槽21内，通过回弹力，卡榫22卡扣于卡槽21内。拆卸时，直接将卡榫22拨出卡槽21即可。
请参阅图5和6，显示本发明第三实施例的挂钩30，此实施例的挂钩30基本类似于第二实施例中的挂钩20，主要不同之处在于固定部17和钩部19的结合方式，其中在图5、6中与图1-2中相同的元件采用相同的标号，在此不再赘述。
在本实施例中，固定部17和钩部19是采用插接结构，如图5所示，钩部19包括插板33和固定于插板33上的钩子34。该插接结构包括分别设置于固定部17的滑槽31和插板33上的滑轨32，当然，可以理解的是，滑槽31和滑轨32也可相互交换，成为分别设置在插板33和固定部17上。滑槽31的上端插入口敞开，而底端封闭形成挡块，以便滑轨32固定在滑槽31内。滑轨32可以是由插板33边缘凸伸出的厚度小于板厚的凸缘，也可以直接就是插板33边缘，并不限于此。使用时，可先将物体挂在钩子34上，再将滑轨32滑入滑槽31，即实现挂物的目的，也可以是先通过滑轨32将钩子34固定于固定部17，再将物体挂在钩子34上，同样可以达到挂物的目的。拆卸时，直接滑出插板33，即可轻松地分离取出固定部17和钩部19。
此外，可以理解的是，固定部17和钩部19之间的可拆卸连接方式并不限于以上实施例，上述方式仅为举例说明，并不以此为限制。
上述各实施例的挂钩中，在钩体16和胶层14之间具有一基层13，避免钩体16直接粘附于胶层14，在使用时，物体不至于对胶层14形成直接牵拉，以增强胶层14的使用寿命，加大粘附强度，使得挂钩能牢固地支撑住物体。而且，通过夹设基层14，可增强挂钩的韧性，不易产生变形，抗拉、抗老化性好，并且在基层14上易于印刷各种所需图案、色彩或纹理，具有应用多样性，实用性强等优点。
此外，在上述实施例中，各种可拆卸连接方式可方便钩部的使用、清洗及取放等，而且只需要将钩部19拆分，固定部17及粘合体12可仍保留固定在墙面上，增加使用便利性。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
