一种多功能桌面支架
技术领域
本发明涉及液晶支架技术领域，特别涉及一种多功能桌面支架。 
背景技术
随着科技的进步和社会的发展，生活水平的日益提高，液晶显示器已经替代传统显示器进入人们的生活当中。液晶显示器的平板结构使其具有更轻更薄更灵活的特性，可以采用多种方式固定安放，与传统显示器相比具有节省室内空间的优势。现有的办公用液晶显示器，一般采用固定式支架直接安放在桌面上，需要占用一部分桌面空间，并且支架和显示器一体设置，其使用高度固定，倾斜角调整有限，平移调整不便，给用户的使用增加了麻烦。因此有必要对目前的支架结构进行改进。 
发明内容
本发明的目的在于针对现有技术的缺陷和不足，提供一种结构紧凑、使用方便的多功能桌面支架。 
为实现上述目的，本发明采用以下技术方案： 
本发明所述的一种多功能桌面支架，包括固定夹，连接在固定夹上端的主轴，两个水平旋转臂，与水平旋转臂一端铰接的背板；所述主轴上设有升降调节器，升降调节器包括转轴支架、涨紧套筒和卡位螺母，转轴支架两侧均设有筒套，转轴支架下端设有螺纹接口，两个水平旋转臂的另一端通过转动销与对应的筒套铰接；涨紧套筒的下端设有若干涨紧片，卡位螺母内设有与螺纹接口配合的内螺纹，卡位螺母的下端口内设有锁紧环；涨紧套筒套设于主轴上，转轴支架套设于涨紧套筒上部，卡位螺母套设于涨紧套筒下 部且与螺纹接口连接，锁紧环扣住涨紧片进而使转轴支架固定在主轴上。 
进一步地，所述若干涨紧片沿主轴外缘均匀间隔设置，若干涨紧片下部的外径从下至上逐渐增大呈锥面设置，涨紧片的外缘上设有止行块，止行块设于锥面的的尾部。 
进一步地，所述涨紧套筒上端设有扣环，扣环的外径大于转轴支架的内径。 
进一步地，所述卡位螺母下方的主轴上套设有穿线夹。 
进一步地，所述固定夹呈U形结构设置，主轴下端固定连接在固定夹的上片上，固定夹的下片上穿设有螺旋调节杆，螺旋调节杆的上端设有与上片配合的夹头。 
本发明有益效果为：本发明结构合理，通过固定夹可连接在办公桌面的侧缘上，减少桌面办公面的占用；升降调节器通过涨紧套筒与卡位螺母配合，在主轴上固定后结构稳定，卡位螺母的旋转行程由止行块限制，避免过渡旋转造成卡位螺母爆裂，升降调节方便快捷；通过水平旋转臂可方便的调节固定在背板上液晶显示器的放置角度，使办公使用更加人性化。

具体实施方式
下面结合附图对本发明作进一步的说明。 
本发明所述的一种多功能桌面支架，包括固定夹10，固定夹10用于连接办公桌面的边缘，固定夹10夹住桌面后使支架整体固定在桌面上，进而减少对办公桌面空间的占用；连接在固定夹10上端的主轴20，主轴20竖直设置，两个水平旋转臂30以及与水平旋转臂30一端铰接的背板40，背板40与液晶显示器连接，水平旋转臂30可升降的连接在主轴20上，进而使连接在主轴20上的液晶显示器悬空设置。 
上述主轴20上设有升降调节器，升降调节器包括转轴支架50、涨紧套筒51和卡位螺母52，转轴支架50两侧均设有筒套50a，转轴支架50下端设有螺纹接口50b，两个水平旋转臂30的另一端通过转动销54与对应的筒套50a铰接；涨紧套筒51的下端设有若干涨紧片51a，卡位螺母52内设有与螺纹接口50b配合的内螺纹，卡位螺母52的下端口内设有锁紧环52a；涨紧套筒51套设于主轴20上，转轴支架50套设于涨紧套筒51上部，卡位螺母52套设于涨紧套筒51下部，卡位螺母52与螺纹接口50b旋紧时，锁紧环52a沿涨紧片51a上升并逐渐扣住涨紧片51a，直到使涨紧片51a完全与主轴贴紧产生足够的摩擦力，进而使转轴支架50固定在主轴20上。 
上述若干涨紧片51a沿主轴20外缘均匀间隔设置，若干涨紧片51a下部的外径从下至上逐渐增大呈锥面设置，进而当卡位螺母52与螺纹接口50b旋紧时，锁紧环52a沿涨紧片51a上升并逐渐扣住涨紧片51a，直到使涨紧片51a直径缩小并完全与主轴贴紧产生足够的摩擦力；涨紧片51a的外缘上设有止行块51b，止行块51b设于锥面的的尾部，止行块51b为卡位螺母52的螺 旋行程重点，避免卡位螺母52过度旋紧造成自身的爆裂或者与螺纹接头50b咬死。 
上述涨紧套筒51上端设有扣环51c，扣环51c的外径大于转轴支架50的内径，扣环51c用于在安装时与转轴支架50一体，转轴支架50套设在涨紧套筒51上后在套入主轴20。 
上述卡位螺母52下方的主轴20上套设有穿线夹53，穿线夹53用于固定液晶显示器的连接线，穿线夹53的上端卡接在卡位螺母52上，水平旋转臂30上也设有对应的穿线器。 
上述固定夹10呈U形结构设置，主轴20下端固定连接在固定夹10的上片11上，固定夹10的下片12上穿设有螺旋调节杆13，螺旋调节杆13的上端设有与上片11配合的夹头14，固定夹10设置在办公桌面的边缘，其上片11与下片12分别插入桌面两侧，下片12上的螺旋调节杆13调节夹头14与上片11之间的间距，进而夹紧桌面使支架整体固定在桌面上。 
以上所述仅是本发明的较佳实施方式，故凡依本发明专利申请范围所述的构造、特征及原理所做的等效变化或修饰，均包括于本发明专利申请范围内。
