Description

紧固装置和紧固方法 技术领域 本发明涉及一种紧固装置和紧固方法， 特别地， 涉及一种将配电箱控制面板紧固到配电 箱的紧固装置和紧固方法。 背景技术 用于配电箱的绝大部分的控制面板， 例如 HMI和 NC面板， 即人机交互界面和数控控制 单元， 都需要使用紧固螺钉安装到配电箱， 并且紧固螺钉要求特定的扭矩。 在这种情况下， 当用户在将 HMI和 NC面板固定在配电箱上时， 需要将安装卡扣放进 HMI和 NC面板的格 栅内， 再将螺钉拧紧， 并确保产品被完全固定。 为了防止因螺钉扭矩过大而造成螺钉滑牙或 者卡扣张开， 在产品说明书上会对螺钉的最大扭矩有要求， 但是如果用户使用手动安装， 扭 矩则很难控制在要求范围内， 这容易造成安装卡扣连同螺钉一起发生倾斜， 影响安装性和用 户体验。 此外， 由于是利用螺钉来夹紧配电箱， 因此需要额外的安装工具 (例如， 螺丝刀)来 完成。
为此， 如何能够使诸如 HMI和 NC面板的配电箱控制面板方便、 快捷地安装并固定到 配电箱成为本领域亟待解决的课题。 发明内容 有鉴于此， 本发明提出了一种紧固装置和一种配电箱控制面板， 利用该紧固装置， 配 电箱控制面板能够方便、 快捷地安装并固定到配电箱。 本发明还提出了一种包括上述紧固装 置和配电箱控制面板的配电箱控制面板组件， 以及一种使用紧固装置将配电箱控制面板紧 固到配电箱的方法。
根据本发明的一方面， 紧固装置包括推块、 偏压构件、 壳体和套设在壳体内的锁止 构件， 偏压构件在纵向方向上定位在推块与壳体之间并且能够变形以提供紧固力， 锁止 构件为弯折结构以在横向方向上具有弹性， 并且锁止构件具有在横向方向上沿相反方向 从壳体两侧突出的齿状结构， 当锁止构件在横向方向上被向中心按压时， 齿状结构能够 缩回到壳体内。
优选地， 紧固装置用于将配电箱控制面板紧固到配电箱， 当紧固装置安装在配电箱 控制面板中时， 推块抵靠在配电箱上， 并且锁止构件的齿状结构与设置在配电箱控制面 板的紧固装置安装部的两侧的对应齿状结构接合。
优选地， 配电箱控制面板是 HMI面板或 NC面板， 即人机交互界面或数控控制单元。 优选地， 偏压构件是弹簧， 更优选是螺旋弹簧， 并且紧固力是弹簧的回复力。
优选地， 推块与偏压构件可拆卸地或永久性地连接， 壳体与偏压构件可拆卸地或永 久性地连接， 壳体与锁止构件可拆卸地或永久性地连接。
优选地， 壳体具有中空的开口， 锁止构件通过开口套设在壳体内。
优选地， 壳体包括形成在开口的中心的纵向梁， 该纵向梁的厚度小于壳体的厚度， 并且纵向梁的两侧上分别形成有至少一个突出部， 并且， 锁止构件具有形成在中心部的 纵向贯通的沟槽， 该沟槽的两个侧壁上分别形成有与壳体的纵向梁的所述至少一个突出 部的位置和数量相对应的至少一个凹口。
优选地， 锁止构件具有大致呈底部开口的 "凹"字形的横截面， 并且具有从最底部 的两个边横向向外延伸的延伸部， 锁止构件的齿状结构设置在延伸部的外边缘处。
优选地， 锁止构件的齿状结构由连续或断续的齿构成。
优选地， 推块、 壳体和锁止构件由塑料制成。 根据本发明的另一方面，配电箱控制面板具有用于上述紧固装置的紧固装置安装部， 该紧固装置安装部构造为形成在配电箱控制面板的侧壁中的切口， 并且该紧固装置安装 部的两侧形成有齿状结构， 该齿状结构构造成能够与紧固装置的锁止构件的齿状结构接 合。 根据本发明的又一方面， 配电箱控制面板组件包括上述的紧固装置和上述的配电箱 控制面板。
根据本发明的再一方面， 提出了一种使用上述的紧固装置将配电箱控制面板紧固到 配电箱的方法， 该方法包括如下步骤： 在按压锁止构件的同时， 将紧固装置推入配电箱 控制面板的紧固装置安装部中， 使得推块抵靠在配电箱上； 朝着配电箱的方向进一步推 动紧固装置， 使得偏压构件发生变形； 以及松开锁止构件， 使锁止构件的齿状结构与配 电箱控制面板上的齿状结构接合。
优选地， 使偏压构件发生变形的步骤是使偏压构件的变形量最大。
从上述方案中可以看出， 由于本发明系利用偏压构件的偏压力 (例如，弹簧的弹力)来固 定设备， 并利用具有弯折结构的锁止构件的弹性来实现安装和拆卸。 因此， 用户可以徒手安 装， 非常方便， 即， 安装时沿着配电箱控制面板上的切口将紧固装置推入并压紧， 拆卸时只 需按压锁止构件， 将紧固装置推出即可。 与用螺钉紧固的方法相比， 本发明的紧固装置提供 的紧固力是恒定的， 因此可以实现更稳定、 可靠的紧固。
此外， 本发明的紧固装置无需利用卡扣钩到诸如 HMI和 NC面板的配电箱控制面板的格 栅中， 而是利用锁止构件的齿状结构和配电箱控制面板的切口两侧的齿状结构的接合来实现 拆装， 因此可以兼容各种不同厚度的铁板且拆装起来极为便捷。 附图说明 下面将通过参照附图详细描述本发明的优选实施例， 使本领域的普通技术人员更清 楚本发明的上述及其它特征和优点， 附图中：

图 2为根据本发明的紧固装置在被沿图 1中的箭头 A所示的方向按压时的状态图。 图 3为根据本发明的紧固装置的分解图。
图 4为根据本发明的配电箱控制面板组件的示意图， 特别地示出了根据本发明的配 电箱控制面板的结构。
图 5A和 5B 为配电箱控制面板通过根据本发明的紧固装置安装到配电箱时的示意 图。 具体实施方式 为使本发明的目的、 技术方案和优点更加清楚， 以下举实施例对本发明进一步详细 说明。
如图 1-3所示， 根据本发明的紧固装置 100包括推块 1 10、 偏压构件 120、 壳体 130 和套设在壳体 130内的锁止构件 140。 偏压构件 120在纵向方向上定位在推块 1 10与壳 体 130之间并且能够变形以提供紧固力。 锁止构件 140为弯折结构以在横向方向上具有 弹性， 并且该锁止构件 140具有在横向方向上沿相反方向从壳体 130的两侧突出的齿状 结构 143。 如图 1 中的箭头 A所示， 当锁止构件 140在横向方向上被向中心按压时， 齿 状结构 143能够缩回到壳体 130内， 如图 2所示。
推块 1 10可以为大致长方体形状， 具有用于抵靠配电箱的第一侧 1 1 1和相反的第二 侧 1 12。 推块 1 10优选由塑料制成， 例如通过注塑法， 但也可以由其它合适的材料制成。 如图所示， 推块 1 10的第二侧 1 12上可以形成有一个或多个突出部 1 13， 用于接收偏压 构件 120。 本领域技术人员应当理解， 推块 1 10的第二侧 1 12可以具有任何适于与偏压 构件接触的构造， 而不限于这里所示的那样， 而且推块 1 10可以与偏压构件 120可拆卸 地或永久性地连接。
偏压构件 120可以是在纵向方向上定位在推块 1 10与壳体 130之间的弹簧， 优选是 螺旋弹簧。偏压构件 120可以通过变形产生回复力， 该回复力用作紧固力。偏压构件 120 具有与推块 1 10的第二侧 1 12相连的第一端 121和与第一端 121相反的第二端 122。 根 据具体的应用场合， 偏压构件 120的数量可以是一个或多个。
壳体 130可以为大致长方体形状， 具有与偏压构件 120相连的第一侧 131和与第一 侧 131相反的第二侧 132， 并具有中空的开口 133。 开口 133除了用于容纳锁止构件 140 夕卜， 还为用户接近锁止构件 140而进行操作提供空间。 从壳体 130的第一侧 131延伸到 第二侧 132的纵向梁 134形成在开口 133的中心， 该纵向梁 134的厚度小于壳体 130的 厚度。 纵向梁 134的两侧上分别形成有至少一个突出部 135， 用于卡合锁止构件 140。 壳 体 130优选由塑料制成， 例如通过注塑法， 但也可以由其它合适的材料制成。 如图所示， 壳体 130的第一侧 131上可以形成有一个或多个突出部 136， 用于接收偏压构件 120。 本 领域技术人员应当理解， 壳体 130的第一侧 131可以具有任何适于与偏压构件接触的构 造， 而不限于这里所示的那样， 而且壳体 130可以与偏压构件 120可拆卸地或永久性地 连接。
锁止构件 140为弯折结构， 从而在横向方向上具有弹性。 锁止构件 140具有形成在 中心部的纵向贯通沟槽 141， 该沟槽 141 的两个侧壁上分别形成有与壳体 130的纵向梁 134的突出部 135的位置和数量相对应的至少一个凹口 142， 当锁止构件 140从壳体 130 的开口 133的底部安装到壳体 130时，突出部 135和凹口 142卡合，从而使锁止构件 140 和壳体 130彼此固定在一起。虽然在图示的示例中锁止构件 140和壳体 130通过壳体 130 的纵向梁 134上的突出部 135和锁止构件 140的沟槽 141的凹口 142卡合而可拆卸地固 定， 但是本领域技术人员明白， 锁止构件 140和壳体 130可以彼此永久性地固定， 例如 通过粘接。
锁止构件 140具有在横向方向上沿相反方向从壳体 130的两侧突出的齿状结构 143， 用于与配电箱的控制面板上的齿状结构接合。 优选地， 如图 3所示， 锁止构件 140的弯 折结构具有大致呈底部开口的 "凹" 字形的横截面， 并且具有从最底部的两个边横向向 外延伸的延伸部 144， 锁止构件 140的齿状结构 143设置在延伸部 144的外边缘处。 锁 止构件 140优选由塑料制成， 例如通过注塑法， 但也可以由其它合适的材料制成。 虽然 图中示出锁止构件 140的齿状结构 143 由连续的齿构成， 但是本领域技术人员明白， 齿 状结构 143也可以由断续的齿构成。
锁止构件 140在未受力的状态下， 如图 1所示， 锁止构件 140的齿状结构 143沿横 向方向延伸或突出到壳体 130的外部 (图 1 中仅一个齿状结构 143可见)。 当沿着箭头 A 所示的方向从两侧按压锁止构件 140时， 如图 2所示， 锁止构件 140的齿状结构 143可 以缩回到壳体 130内， 即向内收缩成与壳体 130的边缘齐平或收缩到壳体 130的边缘之 内（图 2中仅一个齿状结构 143可见）。
下面参照图 4和 5描述与本发明的紧固装置 100—起使用的配电箱控制面板。 如图 4所示， 在诸如 HMI和 NC面板 (即人机交互界面和数控控制单元)的配电箱控制面板 200 上形成有紧固装置安装部 210， 该紧固装置安装部 210例如是配电箱控制面板的侧壁中 的切口， 紧固装置 100可以在横向方向上容纳在该紧固装置安装部 210中。 在紧固装置 安装部 210的两侧形成有齿状结构 220， 齿状结构 220构造成在紧固装置 100置于紧固 装置安装部 210中时， 紧固装置 100的锁止构件 140的齿状结构 143能够与紧固装置安 装部 210的齿状结构 220接合。 紧固装置安装部 210可以在适当位置以任意数量形成在 配电箱控制面板 200的四个侧壁中， 以保证配电箱控制面板 200可以稳固地安装到配电 箱。
图 5示出了紧固装置 100的安装方法。 首先， 在按压锁止构件 140的同时， 将紧固 装置 100推入配电箱控制面板 200的紧固装置安装部 210中， 使得推块 1 10抵靠在配电 箱 300上。 然后， 朝着配电箱 300 的方向进一步推动紧固装置 100， 使得偏压构件 120 发生变形， 优选是最大变形量， 但用户也可以根据实际情况自行控制偏压构件的变形量， 以控制紧固力的大小。 最后， 松开锁止构件 140， 使锁止构件 140的齿状结构 143与配 电箱控制面板 200上的齿状结构 220接合，由此配电箱控制面板 200被紧固到配电箱 300。 相应地， 紧固装置 100的拆卸方法是： 按压锁止构件 140， 使锁止构件 140的齿状结构 143缩回， 偏压构件 120的紧固力去除， 再将紧固装置 100从配电箱控制面板的紧固装 置安装部中拉出。
根据本发明的紧固装置 100用于将诸如 HMI面板和 NC面板的配电箱控制面板 200 紧固到配电箱 300， 当该紧固装置 100放入配电箱控制面板 200的紧固装置安装部 210 中时， 推块 1 10抵靠在配电箱 300上， 并且锁止构件 140的齿状结构 143与设置在配电 箱控制面板 200的紧固装置安装部 210的两侧的对应齿状结构 220接合， 使得位于壳体 130与推块 1 10之间的偏压构件 120保持变形， 从而提供恒定的紧固力。 需要指出， 虽然描述了本发明的紧固装置用于将配电箱控制面板紧固到配电箱， 但 是本发明的紧固装置不限于此应用场合， 而是可以用于任何需要使两个部件或组件或装 置或设备彼此贴合而紧固的场合。
由于本发明系利用偏压构件的偏压力 (例如， 弹簧的弹力)来固定设备， 并利用具有弯折 结构的锁止构件的弹性来实现安装和拆卸。 因此， 无需任何额外工具， 用户可以徒手完成安 装， 方便快捷； 并且本发明的紧固装置提供的紧固力是恒定的， 可以实现更稳定、 可靠的紧 固。 此外， 本发明的紧固装置可以兼容各种不同厚度的铁板， 兼容性好。
以上所述仅为本发明的较佳实施例而已， 并不用以限制本发明， 凡在本发明的精神 和原则之内， 所作的任何修改、 等同替换、 改进等， 均应包含在本发明的保护范围之内。
