Description

带滑动式键盘托的升降台 技术领域
本发明涉及家具技术领域，具体讲是一种带滑动式键盘托的升降台。
背景技术
目前，摆放于桌面上的升降台已经逐渐在人们的日常生活中普及，多用于学习、办公及娱乐等各个领域。它通常包括桌板、底座和升降装置，桌板通过升降装置连接在底座上，底座摆放于桌面上。现有技术的升降工作台一般都配备有键盘托，该键盘托通过支架与工作台的底座连接，其连接方式一般是通过螺丝固定连接，这种结构存在的缺点是在拆装键盘托时，必须借助手动工具才能将键盘托进行拆装，因此操作比较麻烦，且拆装键盘托耗时较长，无法实现快速拆装的要求。现有技术中还出现一种可卸式插装在升降台上的键盘托，它在桌板上设置固定连接板，在键盘托上设置挂板，挂板挂接在固定连接板上。但是，这种带挂接式键盘托的电动升降台具有的缺点是：由于挂接通常只是在定点的位置处进行键盘托高度的调整，不能实现随时随处可停的操作，因此，键盘托的高度选择范围较小，适应人群较小；另外，为了适应人体工学，普通的电脑桌均将键盘托设置在桌面以下，但是现有技术中放置于桌面上的电动升降台的键盘托的最低位置均位于桌面处，并不能调节至桌面以下的位置，因此，现有技术的电动升降台的键盘托并不符合人体工学的要求。
发明内容
本发明所要解决的技术问题是，提供一种能将键盘托随时锁定在任意高度，从而适用不同使用者的要求来符合人体工学，并且操作简便灵活的带滑动式键盘托的升降台。
为解决上述技术问题，本发明提供的带滑动式键盘托的升降台，包括桌面板、底座、用于连接桌面板和底座的支撑腿以及连接于桌面板上的键盘托，底座放置于工作台面上；所述键盘托竖直方向滑动连接在桌面板上并通过锁紧装置锁紧，键盘托在竖直方向上的行程从工作台面下方至工作台面上方。
所述键盘托通过滑动结构与桌面板连接，该滑动结构为套管结构，桌面板连接在套管结构的上端，键盘托连接在套管结构的下端。
所述套管结构包括上连接板、内滑套、外滑套、外罩壳和下连接板；所述上连接板呈L形，其中L形一边与桌面板固定连接，L形另一边与内滑套固定连接，内滑套与外滑套滑动 连接，外滑套与外罩壳固定连接，下连接板水平设置且连接在外罩壳的下端，键盘托固定连接在下连接板上。
所述外滑套、外罩壳和下连接板连接在一起；其中，所述外罩壳的边缘处设螺纹孔，下连接板通过螺钉从下往上连接于外罩壳的螺纹孔处；所述下连接板上设有扣槽，外滑套的底端设有与扣槽扣接的卡扣。
所述的锁紧装置安装在外罩壳处，外滑套的侧壁上对应锁紧装置处设有通孔，锁紧时锁紧装置中的锁紧块穿过通孔压紧在内滑套的侧壁上。
所述的锁紧装置还包括手柄、手柄支座和压帽；手柄支座固定连接在外罩壳的侧壁上，手柄铰接在手柄支座上，手柄支座底面上设有小通孔；压帽包括板状的帽沿和带底的帽筒，帽沿位于外罩壳侧壁内侧，帽筒穿过外罩壳的侧壁和手柄支座上的小通孔与手柄抵紧；所述的锁紧块的形状为与压帽形状相配的带帽沿的帽子状，锁紧块的帽筒紧配在压帽的帽筒内，锁紧块的帽沿卡接在压帽的帽沿处，并且锁紧块的帽沿端面位于压帽的帽沿端面外，锁紧时锁紧块的帽沿端面与内滑套的侧壁抵紧；所述的手柄的转动面包括平面和弧面，其中平面到手柄转动中心的距离大于弧面到手柄转动中心的距离，锁紧时手柄的平面与帽筒抵紧，松开时手柄的弧面与帽筒接触。
采用以上所述的结构后，本发明与现有技术相比，具有以下的优点：
1)由于键盘托是滑动连接在桌面板上的，使用者只需通过松开锁紧装置来调整键盘托到合适的高度再锁紧锁紧装置即可，因此，键盘托随时锁定在任意高度，从而适用不同使用者的要求来符合人体工学，并且操作简便灵活；
2)滑动部分的结构，通过内滑套和外滑套的滑动配合，调节更加顺滑；并且外滑套穿过外罩壳直接与下连接板扣接，使连接结构更加简单；
3)锁紧装置采用了手柄上的弧面和平面的结合压紧，相当于凸轮的结构，在半径小的地方锁紧，在半径大的地方锁紧，只需通过手柄的扳动即可，操作简单便捷。

具体实施方式
下面结合具体实施方式对本发明作进一步详细地说明。
由图1～图7所示的本发明带滑动式键盘托的升降台的结构示意图可知，包括桌面板1、底座3、用于连接桌面板1和底座3的支撑腿2、连接于桌面板1上的键盘托4，底座3放置于工作台面上。所述键盘托4竖直方向滑动连接在桌面板1上并通过锁紧装置锁紧，键盘托4在竖直方向上的行程从工作台面下方至工作台面上方。
所述键盘托4通过滑动结构与桌面板1连接，该滑动结构为套管结构，桌面板1连接在套管结构的上端，键盘托4连接在套管结构的下端。
所述套管结构包括上连接板5、内滑套6、外滑套7、外罩壳8和下连接板9。所述上连接板5呈L形，其中L形一边与桌面板1固定连接，L形另一边与内滑套6固定连接，内滑套6与外滑套7滑动连接，外滑套7与外罩壳8固定连接，下连接板9水平设置且连接在外罩壳8的下端，键盘托4固定连接在下连接板上。
所述外滑套7、外罩壳8和下连接板9连接在一起。其中，所述外罩壳8的边缘处设螺纹孔18，下连接板9通过螺钉从下往上连接于外罩壳8的螺纹孔18处。所述下连接板9上设有扣槽14，外滑套7的底端设有与扣槽14扣接的卡扣15。也就是说，外滑套底部与下连接板扣接，外罩壳与下连接板螺钉连接。
所述的锁紧装置安装在外罩壳8处，外滑套7的侧壁上对应锁紧装置处设有通孔16，锁紧时锁紧装置中的锁紧块13穿过通孔16压紧在内滑套6的侧壁上。在本实施例中，锁紧块13为橡胶块，根据使用情况，锁紧时呈变形状态，解锁时呈自然状态。
所述的锁紧装置还包括手柄10、手柄支座11和压帽12。手柄支座11固定连接在外罩壳8的侧壁上，手柄10铰接在手柄支座11上，手柄支座11底面上设有小通孔17。压帽12包括板状的帽沿和带底的帽筒，帽沿位于外罩壳8侧壁内侧，帽筒穿过外罩壳8的侧壁和手柄支座11上的小通孔17与手柄10抵紧。所述的锁紧块13的形状为与压帽12形状相配的带帽沿的帽子状，锁紧块13的帽筒紧配在压帽12的帽筒内，锁紧块13的帽沿卡接在压帽12的帽沿处，并且锁紧块13的帽沿端面位于压帽12的帽沿端面外，锁紧时锁紧块13的帽沿端面与内滑套6的侧壁抵紧。所述的手柄10的转动面包括平面和弧面，其中平面到手柄10转动中心的距离大于弧面到手柄10转动中心的距离，锁紧时手柄10的平面与帽筒抵紧，松开时手柄10的弧面与帽筒接触。
本发明的动作过程如下：当手柄10呈附图5中所示的状态时，锁紧装置呈解锁状态，此时将键盘托4向下或者向下，外滑套7滑动配合在内滑套6上，直至合适的位置处，拉下手柄10，使手柄10呈附图6中所示的状态，手柄10上的平面迫使压帽12向内侧移动，驱使锁紧块13向内侧移动直至锁紧块13的端面与内滑套6的侧壁紧密地挤压在一起，实现锁紧目的。
以上所述，仅是本发明较佳可行的实施示例，不能因此即局限本发明的权利范围，对熟悉本领域的技术人员来说，凡运用本发明的技术方案和技术构思做出的其他各种相应的改变都应属于在本发明权利要求的保护范围之内。比如：
1、所述套管结构包括上连接板、内滑套、外滑套、外罩壳和下连接板；所述上连接板呈L形，其中L形一边与桌面板固定连接，L形另一边与内滑套固定连接，外滑套与内滑套滑动连接，内滑套与外罩壳固定连接，下连接板水平设置且连接在外罩壳的下端，键盘托固定连接在下连接板上。此时，内滑套、外罩壳和下连接板连接在一起；其中，所述外罩壳的边缘处设螺纹孔，下连接板通过螺钉从下往上连接于外罩壳的螺纹孔处；所述下连接板上设有扣槽，内滑套的底端设有与扣槽扣接的卡扣。也就是说，内滑套底部与下连接板扣接，外罩壳与下连接板螺钉连接。在这种结构中，通孔开设于外滑套的底端侧壁上。
2、所述锁紧装置也可以是其他结构，如旋钮装置，通过旋钮上的螺杆穿过外滑套的通孔与内滑套侧壁顶紧来实现内滑套与外滑套的锁紧目的。
