说明书
一种用于固定杆状物的固定装置
技术领域
本发明属于机械技术领域, 涉及一种固定装置, 特别是一种用于固定杆状物的固定装 置。 背景技术
呈杆状的工具, 例如撑货器。 撑货器呈杆状, 用它对货物进行固定, 防止货物在被 运输过程中脱落或是位移。 因此, 撑货器在物流行业中被广泛使用。
但是, 货物运输过程中需要数量比较多的撑货器。 而撑货器又是呈杆状的, 存放不 当会导致撑货器损坏或是变形。 显然, 撑货器的存放是一个有待解决的问题。
为了减少撑货器形变, 通常撑货器是垂直放置的。 但是, 垂直放置时无其它装置对 撑货器进行定位, 使得撑货器容易掉落。 最终无法达到有效存放的目的。
为了解决上述问题, 人们设计出了各种各样的固定装置。 例如, 中国专利(公开号: CN201027731Y) 提供的 "一种杆状物体的固定器", 它是用于固定杆状物体的一种装置, 它包括固定机构、 锁紧机构、 加强筋, 固定机构呈筒状, 锁紧机构呈拱形的钩状且其具有 弹性, 固定机构与锁紧机构之间通过加强筋连为一体。在使用上述的固定器时, 首先通过 其锁紧机构将整个固定器定位在床板或横梁上,然后再通过固定机构处的圆筒状机构将杆 状物套住, 使得被套住的杆状物不会由固定器处脱落。
虽然上述的固定器能将杆状物体牢牢的固定住, 但是在固定过程中是将杆状物穿入 固定机构处, 或是将固定机构套在杆状物体上的。 当杆状物体比较长时, 上述的固定器在 定位杆状物过程中就显得不甚方便。 相应地, 杆状物由固定器处取出时也显得不甚方便。
现有的其它杆状物固定装置也都存在着固定撑货器这种类似的问题。
^:咖
本发明的目的是针对现有技术所存在的上述问题,提供一种能方便定位杆状物且固定 稳定性比较高的用于固定杆状物的固定装置。
本发明的目的可通过下列技术方案来实现:一种用于固定杆状物的固定装置,包括内 部为空腔的本体, 其特征在于, 所述的本体上具有凹入的凹口, 所述凹口的端口处设有能 开闭的固定爪,在本体内还设有能锁定固定爪的定位结构,且当固定爪将本体凹口处关闭 时定位结构将固定爪锁定住。 本用于固定杆状物的固定装置固定在墙壁处,它用于固定呈杆状的撑货器等物品。具 体而言,初始状态下该装置中的固定爪没有将凹口端口处关闭,撑货器的杆部能嵌入凹口 处。一旦撑货器嵌入凹口后, 固定爪将凹口端口处关闭, 与此同时, 定位结构将固定爪锁 定住, 即此时固定爪一直处于将凹口端口处关闭的状态。
位于凹口处的撑货器就被一直卡住, 使得撑货器不能由本体凹口处脱出。
在上述的用于固定杆状物的固定装置中, 所述的固定爪呈弧形且其中部铰接在本体 上, 固定爪的内端位于凹口底部, 固定爪的外端位于凹口的端口的侧部处。 当杆状物, 例 如撑货器的杆部嵌入凹口时,撑货器的杆部会挤压固定爪内端,使得固定爪绕其铰接处摆 动, 即固定爪内端向凹口底部摆动, 固定爪的外端摆动至凹口的端口处, 通过摆动后的固 定爪外端将本体凹口端口处关闭。
在上述的用于固定杆状物的固定装置中,所述的定位结构包括本体内能运动的挡板和 弹簧一,弹簧一的两端分别作用在固定爪和本体上,在弹簧一的弹力作用下固定爪的内端 位于挡板上部。
杆状物的挤压力作用在固定爪上, 固定爪克服弹簧一的弹力后带动挡板一同运动,一 旦固定爪的内端摆动至挡板的下部后,挡板回复原位,在弹簧一的弹力作用下固定爪的内 端始终抵靠在挡板下部。 使得固定爪在挡板和弹簧一的作用下被定位住。
在上述的用于固定杆状物的固定装置中,所述的定位结构还包括设于挡板与本体之间 的弹簧二, 在弹簧二的弹力作用下挡板部分伸于凹口处。
当挡板受力后会克服弹簧二的弹力, 使得挡板运动。一旦挡板受到的外力消除后, 在 弹簧二的弹力作用下挡板就会回复至其初始位置。
在上述的用于固定杆状物的固定装置中,所述的本体内设有导向件,上述的挡板连接 于导向件处且挡板能沿着导向件平移, 上述弹簧二的两端分别作用在导向件和挡板上。
在弹簧二的弹力作用下挡板向外伸出,也就是说挡板部分位于凹口底部,一旦挡板外 端处受力时, 挡板就会克服弹簧二的弹力缩入。一旦挡板的外端处不受外力作用时, 挡板 就会在弹簧二的作用下伸出回复原位。
作为另外一种方案,在上述的用于固定杆状物的固定装置中,所述的本体内设有定位 件,上述的挡板的一端铰接在定位件下部,上述弹簧二的两端分别作用在定位件和挡板上。
显然, 挡板能沿其铰接处在定位件的下部摆动。 即, 固定爪内端挤压挡板后能克服弹 簧二的弹力, 使得挡板绕其铰接处下摆。 当挡板摆动至一定程度后, 固定爪内端与挡板脱 离,此时在弹簧二的作用下挡板复位;在弹簧一的作用下固定爪内端始终抵靠在挡板下部。
在上述的用于固定杆状物的固定装置中,所述的挡板上具有凸出的拔头,在本体内还 设有开启导向件,在开启导向件处设有能沿其平移的开启件,开启件上具有倾斜的抵压面 且抵压面与上述的拔头相接触。
需要将嵌在本体凹口处的杆状物取出时, 推动开启件, 开启件沿着开启导向件移动, 移动后的开启件通其上的抵压面推动拔头。由于拔头与挡板是固连在一起的,这样就带动 挡板内缩, 从而使得固定爪能摆动, 使本体凹口处为开启状态。杆状物就能由本体凹口处 方便的取出。
在上述的用于固定杆状物的固定装置中,所述的本体上具有两个凹口,所述的两个凹 口处对称的设置有固定爪和定位结构。
显然, 这样使得一个固定装置就能定位两个呈杆状的工具。
在上述的用于固定杆状物的固定装置中, 所述的开启件呈 Y形, 且 Y形开启件的两 内侧分别与上述挡板的拔头接触。
通过同一个开启件就能同时使两个挡板内缩。
在上述的用于固定杆状物的固定装置中, 所述的本体外侧罩有壳体。通常, 壳体是由 塑料材料制成的, 这样使得本固定装置外形紧凑。
在上述的用于固定杆状物的固定装置中,所述的本体上还设有锁杆,锁杆的内端位于 两个挡板之间且在锁杆内端具有凸出的凸头,锁杆的外端部分伸出壳体。凸头能阻挡住挡 板, 也就是说当锁杆不转动时挡板抵靠在凸头上, 使得挡板始终处于伸出状态。
需要使挡板缩回时, 必须先转动锁杆使得凸头脱离挡板处。
与现有技术相比, 本用于固定杆状物的固定装置只需要将杆状物嵌在本体的凹口处, 通过固定爪和定位结构就能将杆状物固定住。同时,杆状物嵌入本体凹口处后固定爪始终 将凹口端口处关闭, 这样使得它不仅能牢牢的将杆状物固定, 而且固定稳定性比较高。
同时, 在本体上设置的锁具使得它的安全性得到进一步的提升。而且, 整个装置外部 设置的壳体使得它外形整洁、 美观, 具有比较高的实用价值。 附图说明

实施例一
如图 1所示, 一种用于固定杆状物的固定装置, 它包括一个内部为空腔的本体 1, 在 本体 1上具有凹入的凹口 2。
如图 1和图 2所示, 在本体 1内铰接有固定爪 3, 固定爪 3呈弧形且其中部铰接在本 体 1上。固定爪 3的内端位于凹口 2的底部处,固定爪 3的外端位于凹口 2端口处的侧部。
如图 3和图 4所示, 在本体 1内还设有定位结构, 通过定位结构能锁定固定爪 3。 定 位结构设于本体 1内的挡板 4、 弹簧一 5、 弹簧二 6等。
本体 1内设有导向件 7,上述的挡板 4连接于导向件 7处且挡板 4能沿着导向件 7平 移, 上述弹簧二 6的两端分别作用在导向件 7和挡板 4上。也就是说, 在弹簧二 6的弹力 作用下挡板 4是伸出的。 本实施例中, 挡板 4伸出的外端为倾斜的斜面。
弹簧一 5的两端分别作用在固定爪 3和本体 1上,在弹簧一 5的弹力作用下固定爪 3 的内端位于挡板 4的上部。
本实施例中, 本体 1上具有两个凹口 2, 这两个凹口 2处均设有固定爪 3和定位结构 且两个凹口 2处的固定爪 3和定位结构对称设置。
在挡板 4上具有凸出的拔头 4a。在本体 1内设有开启导向件 8, 本实施例中, 开启导 向件 8固连在导向件 7上部,在开启导向件 8与导向件 7之间形成一个通孔,通孔处设有 能沿其移动的开启件 9。 开启件 9呈 Y形, 且 Y形开启件 9叉口处的两内侧为倾斜的抵 压面 9a, 上述两个挡板 4的拔头 4a分别与开启件 9的两个抵压面 9a接触。 本实施例中, 开启件 9的外端罩有一个按钮 15, 需要操作时按动按钮 15即可。
另外, 在开启件 9与开启导向件 8之间设有复位弹簧 16, 按动按钮 15后通过该复位 弹簧 16能使开启件 9回复原位。
为了保持整个装置的外形美观、 结构紧凑, 在本体 1外侧还罩有壳体 10, 壳体 10是 由塑料材料制成的。
另外, 为了增加本装置的安全性, 在本体 1上还设有一根锁杆 11, 锁杆 11的内端位 于两个挡板 4之间, 锁杆 11的内端具有向其两侧凸出的凸头 l la, 且凸头 11a位于两个 挡板 4之间。 锁杆 11的外端部分伸出壳体 10, 且在锁杆 11的外端处设有锁具 12。 只有 当正确的钥匙插入锁具 12, 才能带动锁杆 11转动。 本装置在初始状态时,在弹簧二 6的弹力作用下两个挡板 4都部分伸于凹口 2底部处。 在弹簧一 5的弹力作用下固定爪 3的内端位于挡板 4上部, 固定爪 3的外端位于凹口 2 端口处的侧部。
需要将撑货器等杆状物进行固定时,将撑货器的杆部嵌入凹口 2中, 固定爪 3的内端 受到撑货器的挤压,使得固定爪 3内端克服弹簧一 5和弹簧二 6的弹力由挡板 4的上部摆 动至挡板 4下部, 当固定爪 3摆动至一定程度时,摆动至挡板 4下部的固定爪 3内端与挡 板 4脱离,在弹簧二 6的弹力作用下挡板 4伸出,在弹簧一 5的弹力作用下固定爪 3的内 端抵靠在挡板 4下部, 而固定爪 3的外端摆至本体 1凹口 2的端口处, 此时的固定爪 3 无法移动,也就是说本体 1凹口 2处一直处于关闭状态。而位于凹口 2处的撑货器也被牢 牢的卡持住。
当然, 由于本装置上具有两个凹口 2, 因此它可对两个撑货器进行定位。 与此同时, 由于两个挡板 4均抵靠在锁杆 11内端的凸头 11a上, 使得即使在外力作用下挡板 4也不 会缩回。
需要将撑货器从本体 1凹口 2处取出时, 将钥匙插入锁具 12, 转动锁杆 11, 使锁杆 11 内端的凸头 11a转动。 此时, 两个挡板 4均不受凸头 11a阻挡作用。 然后, 按动开启 件 9, 开启件 9沿着开启导向件 8移动后, 通过其上的挤压面 9a挤动拔头 4a, 带动两个 挡板 4克服弹簧二 6的弹力缩回。
另外, 在本体 1凹口 2处与固定爪 3外端相对的位置固连有一个凸出的卡头 14。 通 过卡头 14与固定爪 3的配合能够更加稳定的对杆状物进行定位。
实施例二
本实施例同实施例一的结构及原理基本相同,不一样的地方在于,本体 1内设有定位 件 13, 挡板 4的一端铰接在定位件 13的下部, 弹簧二 6的两端分别作用在定位件 13和 挡板 4的另一端, 见图 5所示。
