Description

用于调节冰箱内活动部件的限位孔和在冰箱内使用的导轨 技术领域
本发明涉及冰箱技术领域， 具体地说，是一种用于调节冰箱内活动部件 的限位孔和在冰箱内使用的导轨。 背景技术
冰箱是每个家庭所必不可少的电器。为了充分利用冰箱内的空间，往往 会在冰箱内设计多个容置空间。 而在同一个容置空间内， 还会用隔板、瓶座 等进一步分隔。 为了适应不同的用户的不同存放要求， 需要隔板、瓶座的位 置可调。 这就需要设计一种调节机构， 以承载瓶座等部件， 实现位置可调。 现有的调节机构中， 用于实现定位的限位孔均是直的， 也即其孔内各部分的 形状、面积均与开口处相同。这样的限位孔只能允许相应的卡固件垂直的进 出， 因此现有的调节机构结构复杂， 操作困难。 发明内容
本发明要解决的技术问题是提供一种可以稳定可靠地固定，且操作简单 方便的用于调节冰箱内活动部件的限位孔以及在冰箱内使用的导轨。
为了解决上述技术问题，本发明提供了一种用于调节冰箱内活动部件的 限位孔，所述限位孔设置于导轨上，所述限位孔开口处的截面积大于内部的 截面积。
进一步地， 所述限位孔为矩形或为两端呈弧形过渡的长条形。
进一步地， 所述限位孔的至少一个侧面与所述导轨的表面倾斜相交。 进一步地，该与所述导轨的表面倾斜相交的侧面与导轨的表面之间的夹 角为 30~60度。
进一步地，该与所述导轨的表面倾斜相交的侧面与导轨的表面之间的夹 角为 45度。
进一步地， 所述限位孔的纵截面呈梯形。
进一步地， 所述导轨呈垂直方向设置。
进一步地， 所述导轨呈水平方向设置。
根据本发明的另一方面， 还提供了一种在冰箱内使用的导轨， 用于在其 上设置活动部件，该导轨具有上述任一种限位孔。本发明的限位孔配合导向 块与限位块之间的斜面接触的调节机构使用，使得限位块可以斜向滑入和脱 出限位孔， 从而使得调节机构的结构变得更为简单， 成本低， 且调整操作简 单方便。 附图说明

下面结合附图和具体实施例对本发明作进一步说明，以使本领域的技术 人员可以更好的理解本发明并能予以实施，但所举实施例不作为对本发明的 限定。
如图 1至图 2所示， 本发明的限位孔 2设置于导轨 1上， 限位孔 2开口 处的截面积大于内部的截面积。而限位孔 2可以为矩形或为两端呈弧形过渡 的长条形。优选如图 2所示的长条形。限位孔 2的至少一个侧面与导轨 1的 表面倾斜相交， 相交的夹角以 30~60度为宜， 优选为 45度。 具体实施时， 该角度应与相应的调节机构中限位块 5与导向块 4之间的斜面相适应。作为 一种优选的实施方式， 参见图 4~7所示， 限位孔的纵截面呈梯形。
如图 3所示， 配合本发明使用的调节机构 3包括一导轨 1， 导轨 1上设 有限位孔 2， 用于对调节机构 3进行定位固定。 本发明采用单根导轨的优点 是， 操作时活动部件只需要在一根 轨 1上滑动， 因此不会有不同步的问题 产生。
如图 4所示， 调节机构包括导轨 1， 导轨 1上配合设有滑动块 8， 滑动 块 8与导轨 1之间设有限位块 5和导向块 4， 限位块 5与导向块 4之间呈斜 面配合，且限位块 5的一端部延伸至导轨 1上的限位孔 2中； 限位块 5—侧 设有拨动杆 6。 导轨 1与滑动块 8之间的配合方式不作限制， 只要可以保证 滑动块 8可沿导轨 1滑动且不会脱落即可。 例如可以在导轨 1上设置滑槽， 将滑动块 8嵌置于滑槽中； 或者将滑动块 8两侧向内折弯抱住导轨 1等。另 外， 在限位块 5与导向块 4之间还设有弹性件， 弹性件优选为压缩弹簧 7。 而需要调节的部件， 例如搁物架、瓶座（图中未示出）等， 可以安装固定到 滑动块 8上， 也可以与滑动块 8—体成型。
限位块 5与导向块 4之间的斜面与导轨 1轴向的夹角以 30~60度为宜， 优选为 45度。限位块 5与导向块 4之间的配合结构也可以有多种实施方式， 一种优选的方式是在导向块 4上形成倾斜的通道，而限位块 5的一部分穿过 该通道， 并可以在该通道内滑动。参见图 4所示， 在限位块 5的相异于导轨 1的一侧具有一空间， 该空间的存在使得限位块 5可以向左移动一定距离， 而该距离足以使限位块 5从限位孔 2中脱出。
如图 5所示， 当需要向下调整位置时， 向下压拨动杆 6， 拨动杆 6向下 移动，拨动杆 6压迫限位块 5也向下移动，并在向下移动过程中将弹簧 7压 缩。 由于限位块 5与导向块 4之间是斜面配合， 在斜面的导向作用下， 限位 块 5在向下移动的过程会同时向左移动， 从而将其端部从限位孔 2中脱出。 此时调节机构 3可以在导轨 1上自由滑动。此时状态如图 6所示。滑动调节 机构到预定位置， 松开拨动杆 6。 在外力消失后， 弹簧 7顶推限位块 5和拨 动杆 6向上移动复位。 由于斜面的作用， 限位块 5在向上移动的同时会向右 移动，其端部会滑入导轨 1上相应的限位孔 2中，从而将调节装置再次锁定。
当需要向上调整位置时， 只需要向上推滑动块 8， 通过滑动块 8对导向 块 4施加一个向上的力，导向块 4进而对限位块 5施力。在限位块 5与导向 块 4之间的斜面作用下， 导向块 4迫使限位块 5向左移动， 从而从限位孔 2 中脱出。 后续重新锁定操作与上述相同。
上述的实施例中导轨 1呈垂直方向设置。如图 7所示，导轨 1还可以呈 水平方向设置，此时优选滑动块 8与导轨 1之间设有两个限位块，两个限位 块分别朝向两个方向相对设置，两个限位块之间设有弹性件，弹性件优选为 压缩弹簧 7; 两个限位块一侧分别设有拨动杆 6。 当然， 两个拨动杆 6可以 设计为一体。 当需要调整时位置时， 朝欲调整的方向推动拨动杆 6即可。参 见图 7， 以向右调节为例进行更进一步说明。 向右推动拨动杆 6， 拨动杆 6 压迫位于左侧的第一限位块 9向右移动，并在向右移动过程中将弹簧 7压缩。 由于第一限位块 9与导向块 4之间是斜面配合，在斜面的导向作用下，第一 限位块 9在向右移动的过程会同时向一侧移动（即向下侧移动）， 从而将其 端部从限位孔 2中脱出。当第一限位块 9从限位孔 2中完全脱出后，其与拨 动杆 6之间不能再产生相对运动。 继续推动拨动杆 6， 可以对导向块 4施加 一个向右的力， 导向块 4进而对位于右侧的第二限位块 10施力。 在第二限 位块 10与导向块 4之间的斜面作用下，导向块 4迫使第二限位块 10向一侧 移动（即向下侧移动）， 从而使用其从限位孔 2中脱出。此时调节机构可以 在导轨 1上自由滑动。 滑动调节机构到预定位置， 松开拨动杆 6。 在外力消 失后， 弹簧 7顶推两个限位块和拨动杆复位。限位块端部会滑入导轨 1上相 应的限位孔 2中，从而将调节装置再次锁定。这种结构可以实现双向可靠锁 定， 并可方便地调节， 适用于水平调节的场合。
以上所述实施例仅是为充分说明本发明而所举的较佳的实施例，本发明 的保护范围不限于此。本技术领域的技术人员在本发明基础上所作的等同替 代或变换，均在本发明的保护范围之内。本发明的保护范围以权利要求书为 准。
