本发明目的的实现、功能特点及优点将结合实施例，参照附图做进一步说明。
具体实施方式
应当理解，此处所描述的具体实施方式仅仅用以解释本发明，并不用于限定本发明。
参照图1，图1为本发明第一实施例中胶框1和挡墙10的立体结构示意图。
本实施例中，胶框1的材质可以为塑胶，呈方形框架设置，各边上设有若干用以定位液晶玻璃100的挡墙10，该挡墙10具有块状定位段101，该定位段101的前端与液晶玻璃100接触。定位段101后端设有固定段102，该固定段102沿定位段101的后端延伸，与定位段101侧面形成外张角（本实施例中为90°）。具体来说，本实施例的挡墙10呈“T”形设置，“T”形的竖向段为定位段101，与液晶玻璃100接触，多个定位段101合围成一个用于定位液晶玻璃100的容置框（图中未示出）；“T”形的横向段为固定段102，该固定段102用于与胶框1连接。本实施例中，定位段101的长度可调，例如，定位段101设置成不同的尺寸系列或设置成螺纹可调结构，以匹配不同尺寸的液晶玻璃100。胶框1上具有用以定位挡墙10的收容框11。该收容框11突出于胶框1的表面，具有开口端111和卡槽112。挡墙10可平放在收容框11内，定位段101的前面凸出于开口端111的端平面，以定位液晶玻璃100。开口端111的开口宽度W与定位段101的宽度w基本一致，用于左右定位挡墙10。卡槽112的高度H与固定段102的高度h基本一致，用于前后定位挡墙10。连接时，只需将各部位对应卡合即可。本实施例中的挡墙10采用与胶框1相同的塑胶材质，与胶框1在一套模具中成型。在其它实施例中，挡墙10也可以采用硬度小于胶框1的塑胶材质。
由于挡墙10与胶框1可拆卸地连接，从而可以调节挡墙10在胶框1上的相对位置，使得上述容置框可适配于多种尺寸的液晶玻璃100。例如，遇到尺寸不同的液晶玻璃100时，只需将定位段101的尺寸调节到与液晶玻璃100适配，再将挡墙10与收容框11配装即可，从而实现不需开模也可以定位不同尺寸的液晶玻璃100。相对于现有技术中胶框1与挡墙10一体成型的方式，本发明可大大减少开模费用。应当说明的是，本实施例中固定段102的形状除了图1所示的方形外，还可以是三角形或弧形（例如半圆形等），对应的，胶框1上的卡槽112与其配作。
参照图2，图2是本发明第二实施例中胶框2的结构示意图。本实施例中，挡墙可以是第一实施例中的挡墙10。胶框2上设有呈分层设置、每一层均可卡持固定段102的卡槽21，卡槽21可以按图2所示形状直接从胶框2的表面凹陷成型，也可设置一凸出胶框2表面的框体，将卡槽21设置在框体的内侧壁上。卡槽21的前端设置有开口211。前一层卡槽21与后一层卡槽21的形状和大小相同，两者相间隔的距离以及层数可根据胶框2的边的宽度选择，可实现微调容置框的尺寸即可。本实施例中卡槽21的层数优选为3层。
参见图3，图3为本发明胶框第二实施例挡墙的结构示意图。
进一步的，挡墙10的另一个优选方案可以为：固定段102为三角形（如图3所示），也呈分层设置，各层的形状和大小相同。这样与卡槽11连接时，可以多层卡槽21对应连接，使得挡墙10与胶框2连接更为稳固。应当说明的是，本实施例中，固定段102的形状除了本实施例中的三角形外，也可以是图1所示的方形，或者其它实施例中的半圆形，只要可前后定位挡墙10即可。
由于卡槽21呈分层设置，装配时可根据液晶玻璃100的尺寸，选择性的将挡墙10的固定段102定位在某一层卡槽21上，使挡墙10的定位段101改变定位位置，从而调整容置框的大小，使其与不同尺寸的液晶玻璃100适配。
参照图4，为本发明第三实施例中胶框3的结构示意图。该实施例中，胶框3的各边上设有卡槽31，卡槽31沿胶框3上液晶玻璃100所在侧向该侧的对面延伸设置为多排，每排设置有多个卡槽31。排与排之间间隔的距离根据胶框3的边的宽度选择。边较宽时，可设置两排以上的卡槽31；边较窄时，可设置两排卡槽31，只是调节的范围相对较小。本实施例中，卡槽31实际上是一个扣槽，其底部设有扣台（图中未示出）。挡墙10为一条形塑胶块或塑胶盒，仅具有定位段101，而没有固定段102。在定位段101的底部设有与卡槽31适配的扣体（图中未示出），该扣体与卡槽31扣接，将挡墙10与胶框3连接。当需要调整容置框的尺寸时，只需将挡墙10与合适位置的卡槽31扣接即可，调整起来方便、省力。
参照图5，为本发明第四实施例中胶框4的结构示意图。挡墙10为中空设置，具体地，挡墙10为一四方框体，该四方框体内腔侧壁设有多个卡槽103，该卡槽103按第二实施例中卡槽21的形式分层设置。胶框4上设有与该挡墙10内腔配作、用以定位挡墙10的凸起41。本实施例中，凸起41可以为一个，也可以为多个，每个凸起41的距离相等，形状一致，这样或获得较大的调节范围。
由于设置有卡槽103，挡墙10可在胶框4上后、左、右移动位置，调节定位液晶玻璃100的容置腔的尺寸，实现与各种不同尺寸的液晶玻璃100适配。本实施例中，挡墙10也可通过采用与胶框4相同的塑胶材质，通过一套塑胶模具成型。
此外，也可将凸起41设置挡墙10上，而将卡槽103设置在胶框4上，这样仍可以实现调节。
本发明胶框1、2、3或4可应用在液晶模组中。液晶模组是液晶显示器中的重要组成部分。参照图6，为本发明液晶模组第一实施例的结构示意图。该实施例中，液晶模组具有胶框5，该胶框5可以是前述胶框1、2、3或4。本发明液晶模组中的胶框5由于采用了前述胶框1、2、3或4的结构，本发明液晶模组不需重新开模也可配装多种尺寸不同的液晶玻璃，降低了液晶模组的制造成本。胶框1、2、3、4的结构请参照前述胶框的第一、二、三、四实施例，在此不作赘述。
本发明还提供一种液晶显示器，该液晶显示器可以应用在液晶电视上，除了具有上述液晶模组外，液晶显示器还包括光源组、外壳等构件。由于液晶模组中的胶框采用了上述胶框1、2、3或4的结构，液晶显示器的成本得以大幅降低，液晶显示器及其产品具有更大的市场竞争优势。
本发明并不局限于以上实施方式，在上述实施方式公开的技术内容下，还可以进行各种变化。凡是利用本发明说明书及附图内容所作的等效结构变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
