Description
真空吸盘
技术领域
本发明属于日用五金, 尤其是一种安装在光滑墙面上用于支承物件的吸盘。
背景技术
市面常见的旋钮式真空吸盘通过转动转盘内的斜坡拉起吸盘片中部使之造成真空而能长 时间吸附在墙上, 它的安装使用十分方便, 又不会破坏墙壁。 但是现有产品存在两个不足之 处: 首先, 这种真空吸盘的钩子多是圆杆弯制而成, 圆杆头直接塞进吸盘片中心的圆孔中, 由于圆杆头与圆孔之间的摩擦力有限, 所以钩子总是在挂上物件后偏转向下方, 这样, 就不 能适应把钩子平放或向上的其他使用方式; 其次, 真空吸盘内的爬升件在爬升到斜坡顶部后 便停留在平直段, 在该停留位置没有锁住功能, 吸盘的转盘受到外物小碰擦时容易后退, 解 除了真空, 使吸盘从墙上脱落。
发明内容
为了克服现有产品的缺点, 本发明提供一种真空吸盘, 它的钩子能牢固地保持向任何方 向的安装状态, 并且安装好以后不会轻易地被卸装。
本发明包括盒形的外壳、 下支座、 扭簧和吸盘体; 外壳内部沿壳体圆周有两条以上带斜 坡的滑道, 外壳中心有通孔; 下支座呈环状, 其上有多个柱塞孔以及两个以上凸台; 吸盘体 中心有一连接柱, 连接柱旁边有一挡块, 吸盘体周边有多个柱塞, 连接柱穿出外壳的通孔, 柱塞嵌入下支座的柱塞孔; 扭簧的两头分别与挡块和外壳接触; 其特征在于凸台上有定位球, 凸台通过定位球与滑道接触, 滑道上有定位凹孔, 定位凹孔位于定位球在滑道上的移动路径 上; 连接柱上有卡圈槽, 卡圈槽位于连接柱伸出通孔的部位, 有一个卡圈卡在卡圈槽上; 连 接柱的截面为多边形; 连接柱的末端安装有一个钩子, 钩子的一端有截面同连接柱截面相同 形状的沉孔, 钩子的沉孔套在连接柱末端上。
作为本发明的一种优选结构, 凸台有沉井和弹簧, 定位球和弹簧安装在沉井内。
0 . 作为本发明的另一种优选结构, 定位球固接在凸台上。
作为对本发明的进一步改进, 连接柱的截面为正方形; 钩子上有螺孔, 螺孔与沉孔贯通, 螺孔里有紧定螺钉。
本发明把吸盘片与钩子的连接改进为多边形轴与多边形沉孔嵌套, 使钩子不会因挂物而 偏转, 另外增加了滑道自锁结构, 增强了吸盘吸附的可靠性。 本发明不单能悬挂重物, 还可 以平托重物或上举重物。 它适宜在家庭、 办公室、 商场和宾馆等场合安装使用。

图 7是实施例 1的钩子安装在吸盘上的外观图;
图 8是实施例 2移出卡圈和外壳的外观图 (外壳部分剖切);
图 9是由两个吸盘构成的毛巾架外观图。
具体实施方式
以下结合附图和实施例对本发明作进一步详细说明。
参见图 1至图 3, 外壳 1用金属或塑料制成, 外壳 1呈盒形, 外壳 1 中心设置了一个圆 筒状的缩入部 25, 其上有一个通孔 6; 外壳 1 内部沿壳体圆周有三条滑道 5, 每条滑道 5由 一段平直段和一段斜坡平滑连接而成; 每条滑道 5上都有一个半球状的定位凹孔 13。
下支座 2用金属或塑料制成, 下支座 2呈环状, 其上均匀分布有十六个柱塞孔 7、 三个 凸台 8以及三个第二凸台 22; 每个凸台 8都有一个沉井 19和一个弹簧 18, 定位球 12是一颗
钢珠,钢珠和弹簧 18安装在沉井 19内, 定位球 12在滑道 5上移动时可以落入滑道 5上的定 位凹孔 13。 设置钢珠和弹簧使得转动外壳时的手感特别好。
吸盘体 4中心延伸出一条连接柱 9, 这条连接柱是用金属制作, 其尾部固定在柔性硅橡 胶制的吸盘中心。 连接柱 9的截面为方形, 其上其上制有一裂缝 27; 连接柱 9旁边有一矩形 的挡块 10; 柔性吸盘体 4周边有八个柱塞 11。 八个柱塞 11分别嵌入下支座 2的十六个柱塞 孔 7之中的八个; 连接柱 9穿出外壳 1的通孔 6, 连接柱 9上有一个卡圈槽 14, 卡圈槽 14位 于连接柱 9伸出通孔 6的部位, 有一个卡圈 15卡在卡圈槽 14上。
扭簧 3的两头分别抵住挡块 10和缩入部 25上的卡槽 24, 这样扭簧 3的弹力总是力图使 定位球 12沿斜坡落下。
参见图 4, 当外壳 1向右移动时下支座 2凸台 8上的定位球 12从斜坡移动到平直段, 然 后被弹簧 18压入定位凹孔 13, 这时外壳 1与下支座 2间的距离较大, 柔性吸盘体中心部位 被拉起。 因为外壳 1与下支座 2被锁定, 外壳 1不会轻易左移。 图中下支座 2的第二凸台 22 与外壳 1的挡板 23是作外壳 1转动限位之用。 参见图 5, 用力扭动外壳 1向左移动, 迫使下支座 2凸台 8上的定位球 12离幵定位凹孔 13, 从平直段移动到斜坡底部, 这时外壳 1与下支座 2间的距离较小, 柔性吸盘体中心部位被放 下。
参见图 6和图 7, 在吸盘体的连接柱末端安装有一个钩子 16, 钩子 16的一端有同连接柱 9截面相同形状的方形沉孔 17, 钩子 16的沉孔 17套在连接柱 9末端上。 钩子 16上有螺孔 20, 螺孔 20与沉孔 17贯通, 螺孔 20里旋有紧定螺钉 21, 和钩子连接时紧定螺丝攻入连接 柱的裂缝。
参见图 8, 实施例 2同实施例 1的不同点首先在于从每个凸台 8上平面都延伸出一个半 球状的定位凸球 12, 凸台 8通过定位凸球 12与外壳的滑道接触, 这样可以简化结构。 其次 是实施例 2的吸盘体中心的连接柱 9是 ABS或 PC塑料制成, 它注塑在用硅橡胶做的吸盘中
心, 其上没有设置裂缝, 和钩子连接时紧定螺丝顶压在连接柱的表面上; 并且连接在吸盘体 上的挡块 10是圆柱形的。
上述两个实施例子并不是本发明的排他的实施方式, 在另外的实施方式中, 连接柱 9的 截面可以是任何多边形形状, 比如长方形、 五边形、 六边形等等 ·, 外壳 1上的缩入部 25也可 以取消, 使通孔 6就开在外壳 1的上平面上; 钩子的外形也可以作出多样的变化。 图 9中展 示了由两个本发明的真空吸盘和一条横杆构成的毛巾架, 图中, 横杆 26是一个双头的钩子。
