Description

一种按压式反弹缓冲导轨结构 技术领域
本发明涉及铰链的技术领域，尤其是涉及一种按压式反弹缓冲导轨结构。
背景技术
现有的反弹式抽屉往往利用安装抽屉反弹器以实现触压抽屉实现开关，而现有的抽屉反弹器质量参差不一，在使用一段时间后，很容易发生卡死或按压无法关闭的情况，影响抽屉的使用；现市场上的抽屉导轨存在多种工作方式，有的导轨可以在抽屉关闭时缓冲自关，但需要人手拉出抽屉；有的导轨能实现反弹功能，按压抽屉可以使抽屉自动弹出，但抽屉关闭时无缓冲效果，容易出现抽屉撞击声音。
针对上述的问题，本申请人分别在中国专利CN2017202328541、CN2018101381687及CN2018111336832中提出了三种形式的“反弹缓冲锁件”，其中，这类反弹缓冲锁件是固定在抽屉上，从而与导轨的动轨同步滑动，而与反弹缓冲锁件相抵触配合的碰块是设置在导轨的定轨上，这种方式导致在更换/维修抽屉时，需要额外拆下反弹缓冲锁件，操作较为复杂。其次，这类方式需要预先将反弹缓冲锁件安装在抽屉上，由于大部分抽屉的安装空间狭窄有限，导致反弹缓冲锁件在安装时调整操作难度较大。
发明内容
针对现有技术的不足，本发明的目的在于提供一种安装方便简单的按压式反弹缓冲导轨结构。
为实现上述目的，本发明提供的方案为一种按压式反弹缓冲导轨结构，包括两组对称布置的自关缓冲导轨组件和两组对称布置的反弹组件，其中，每组所述自关缓冲导轨组件包括相互滑动连接的动轨和定轨，每组所述反弹组件均包括安装底板及设于安装底板上的反弹锁件，两所述反弹锁件之间通过同步杆相同步配合；其特征在于：所述安装底板可拆卸地活动扣接于定轨上，所述动轨设有用于与反弹锁件的驱动推块相抵触配合的碰块；所述碰块与动轨同步动作，并且所述碰块与反弹锁件相抵触配合以对应触发反弹锁件的储能功能和释能反弹功能。
进一步，所述定轨的底面设有呈前后布置的定位竖轴和卡紧竖轴，所述安装底板前端部成型有与定位竖轴相旋转卡接配合的U型卡口，所述安装底板成型有呈侧开口且与卡紧竖轴相滑动卡接的弧形卡槽，其中，预先将U型卡口与定位竖轴相卡接后，可使安装底板绕定位竖轴旋转动作以令弧形卡槽与卡紧竖轴相滑动卡接配合。
进一步，所述安装底板成型有与定轨底面弹性抵触配合的弹性部，其中，所述弹性部的顶面成型有与定轨底面预开有的定位孔113相配合的定位凸点。
进一步，所述同步杆包括杆体、两个分别与反弹锁件的联动部相配合的同步接头以及两个分别活动套设于杆体两端的固定套件，其中，所述同步接头的外端部成型有供杆体端部嵌装配合的连接卡槽，每个所述固定套件成型有与同步接头的连接卡槽相滑动卡接的固定部。
进一步，所述杆体的截面呈四角星状。
本发明的有益效果为：反弹锁件通过安装底板活动安装至定轨上，同时利用定位竖轴和卡紧竖轴分别与U型卡口及弧形卡槽相配合，从而实现安装底板可绕定位竖装进行旋转拆装，装配操作简单快捷。

具体实施方式
为了便于理解本发明，下面参照附图对本发明进行更全面的描述。附图中给出了本发明的较佳实施方式。但是，本发明可以以许多不同的形式来实现，并不限于本文所描述的实施方式。提供这些实施方式的目的是使对本发明的公开内容理解得更加透彻全面。需要说明的是，本发明所述“第一”、“第二”不代表具体的数量及顺序，仅仅用于名称的区分。
参见附图1至附图5所示，在本实施例中，一种按压式反弹缓冲导轨结构，包括两组对称布置的自关缓冲导轨组件1和两组对称布置的反弹组件2，每组自关缓冲导轨组件1可为由相互滑动连接的动轨12和定轨11组成的两节轨或由相互滑动连接的动轨12、中轨和定轨11组成的三节轨，具体地，动轨12用于与抽屉连接且定轨11用于与柜体侧板连接。
在本实施例中，每组反弹组件2均包括安装底板21和设于安装底板21上的反弹锁 件22，其中，本实施例的反弹锁件22可如本申请人所申请的中国专利CN2017202328541、CN2018101381687及CN2018111336832中所公开的锁件结构，此处不再对锁件结构原理进行赘述，反弹锁件22也可采用相衍生的方式，此处不作限定。两反弹锁件22之间通过同步杆3相同步配合。
在本实施例中，安装底板21可拆卸地活动扣接于定轨11上，具体地，定轨11的底面设有呈前后布置的定位竖轴111和卡紧竖轴112。安装底板21前端部成型有与定位竖轴111相旋转卡接配合的U型卡口211，即，在U型卡口211与定位竖轴111相卡接后，安装底板21可绕定位竖轴111进行旋转摆动，起到预定位的作用。安装底板21成型有呈侧开口且与卡紧竖轴112相滑动卡接的弧形卡槽212，即，弧形卡槽212呈弧形延伸至安装底板21的外侧面，从而卡紧竖轴112可与弧形卡槽212相滑动卡接。因此，安装时，通过预先将U型卡口211与定位竖轴111相卡接后，随后转动安装底板21绕定位竖轴111旋转动作以令卡紧竖轴112相对滑入弧形卡槽212内并沿弧形卡槽212滑动至预置位置，便完成安装底板21的安装操作。反之，拆卸时。通过转动安装底板21绕定位竖轴111旋转动作以卡紧竖轴112组件滑出弧形卡槽212，随后在卡紧竖轴112完全脱离弧形卡槽212后，水平拔出安装底板21以令U型卡口211脱离定位竖轴111，便完成安装底板21的拆卸操作。
优选地，本实施例的定位竖轴111和卡紧竖轴112可为铆钉，通过将铆钉固定在定轨11的底面形成定位竖轴111和卡紧竖轴112，生产方便简单。
在本实施例中，安装底板21成型有与定轨11底面弹性抵触配合的弹性部213，其中，弹性部213的顶面成型有与定轨11底面预开有的定位孔113相卡接配合的定位凸点，由此，在旋转安装底板21到位时，弹性部213的定位凸点卡接至定位孔113中，从而来提示已安装到位，实际操作时会发出“嗒”的金属碰撞声。反之，在拆卸安装底板21时，弹性部213受压而弹性形变，从而使定位凸点退出定位孔113。
参见附图5所示，在本实施例中，同步杆3包括杆体31、两个分别与反弹锁件22的联动部相配合的同步接头32以及两个分别活动套设于杆体31两端的固定套件33，其中，同步接头32的内端部成型有与联动部的联动齿条相啮合的齿轮，预先将同步接头32与联动部相装配。同步接头32的外端部成型有供杆体31端部嵌装配合的连接卡槽321，每个固定套件33成型有同步接口连接卡槽321相滑动卡接的固定部331，即，首先将固定套件33套设在杆体31上，再将杆体31端部嵌装至连接卡槽321内，最后再将固定套件33滑动嵌装至连接卡槽321内，从而通过同步接头32和固定套件33共同限制固定住杆体31的一端，同样地，通过另一组固定套件33和同步接头32对杆体31的另一端进行限位固定，便完成 了两反弹锁件22与同步杆3的同步连接。采用上述的方式，不仅具有安装方便的特点，尤其是适用于狭窄的安装空间，而且还可降低杆体31长度的精度要求，降低生产成本。
进一步，本实施例的杆体31的截面呈四角星状，其中，同步接头32的连接卡槽321与固定套件33的固定部331所围成的区域与缸体的形状相吻合，采用这种方式可避免杆体31发生打滑问题，同步更加精确可靠。
在本实施例中，动轨12设有用于与反弹锁件22的驱动推块相抵触配合的碰块4，由此，所述碰块与动轨同步动作，并且所述碰块与反弹锁件22相抵触配合以对应触发反弹锁件22的储能功能和释能反弹功能，以下结合具体动作分别对储能功能和释能反弹功能作出解释说明。
具体地，储能功能：在推动抽屉关闭时，碰块4随动轨12的关闭动作而朝内移动并与反弹锁件22的驱动推块相碰触，从而触发反弹锁件22的传动组件逐渐移动储能，其中，在碰块4与反弹锁件22的储能过程中，也触发了自关缓冲导轨组件1上预设有的缓冲装置实现自关缓冲功能。待反弹锁件22的传动组件滑动到设定位置进行避让锁定，储能结束；碰块及动轨12继续往内滑动，此时只有自关缓冲导轨组件1的缓冲装置起作用，直至动轨12滑动至停止位置，完成关闭动作。
具体地，释能反弹功能：在抽屉关闭状态下，通过按压抽屉使碰块4随动轨12往内移动碰触反弹组件2的驱动推块，从而触发反弹组件22的传动组件解锁，释放内部储能，进而反弹组件22克服自关缓冲导轨组件1的缓冲装置的作用力，顶触碰块4而带动动轨12往外弹出，直至反弹组件22的驱动推块滑动至预定的避让位后，反弹组件22不再与碰块4相顶触配合，而动轨12依靠惯性作用继续滑出，完成开启动作。
除此之外，本实施例的还具有单开启功能及单缓冲功能，通过不按压且直接外拉开启抽屉，不触发反弹组件2的释能反弹功能，完成单开启功能；在预先通过单开启功能的情况下，通过推动抽屉内闭，不触发的反弹组件2的储能功能。上述两功能下的反弹组件2始终保持储能状态。
具体地，单开启功能：通过直接外拉抽屉，使碰块4随动轨12往外移动，从而顶触反弹组件22的驱动推块往外滑动，此时的反弹组件22的传动组件保持锁定，不会释放内部储能，依靠外部拉力克服自关缓冲导轨组件1的缓冲装置的作用力而拉动抽吸完成开启。
具体地，单缓冲功能：抽屉先前以单开启功能的方式完成开启后，可推动抽屉网内移动，使碰块4随动轨12往内移动，从而抵触反弹组件22的驱动推块往内滑动，由于反弹组件22的传动组件保持锁定，此时并不会触发储能，而在碰块4往内移动的过程中触发了 自关缓冲导轨组件1的缓冲装置实现自关缓冲功能，直至动轨12滑动至停止位置，完成关闭动作。
以上所述之实施例仅为本发明的较佳实施例，并非对本发明做任何形式上的限制。任何熟悉本领域的技术人员，在不脱离本发明技术方案范围情况下，利用上述揭示的技术内容对本发明技术方案作出更多可能的变动和润饰，或修改均为本发明的等效实施例。故凡未脱离本发明技术方案的内容，依据本发明之思路所做的等同等效变化，均应涵盖于本发明的保护范围内。
