发明内容
为了改进现有技术中所存在的问题进一步提高所述滑轨运行的稳定性，本发明提出一种全新的家具滑轨缓冲器，包括缓冲基座及脱扣器，所述缓冲基座包括上、下布置并相互插接连接在一起的滑块和底座、连接在所述底座与所述滑块之间的复位弹簧和能够对所述复位弹簧的回弹力予以缓冲的阻尼缓冲器、能够将所述底座与所述滑块予以锁定的自锁连接扣，所述滑块轴向滑动安装在所述底座上；其特征在于：
(a)所述自锁连接扣包括有前、后布置的第一转动结合部和下钩臂，所述滑块的头端部设置有第二转动结合部，所述自锁连接扣通过所述第一转动结合部转动连接到所述滑块的第二转动结合部上，所述自锁连接扣的转动轨迹平面大致垂直于所述滑块的上表面，所述下钩臂位于所述自锁连接扣的下部并能够钩向所述底座；
(b)在所述底座的尾端部上设置有能够避让所述下钩臂的陷阱以及能够结合所述下钩臂 的钩臂结合部，当所述滑块在所述底座上向后滑出让所述下钩臂达到所述陷阱位置时，所述下钩臂能够向下旋转伸入所述陷阱并钩住所述钩臂结合部进而能够锁定所述滑块制止其反向复位；
(c)在所述自锁连接扣的脊背上前、后布置有上钩臂和第一滑出结合部，所述上钩臂具有插接结构从而让插接其上的物件不能向上脱出，所述第一滑出结合部位于所述下钩臂的上方；
(d)所述脱扣器大致呈板状能够固定连接到滑轨，所述脱扣器包括有能够插接到所述上钩臂上的前叉臂和能够结合所述第一滑出结合部的第二滑出结合部；当所述脱扣器前行而所述前叉臂插接到所述上钩臂中时，所述前叉臂能够带着所述自锁连接扣及所述滑块前行但不能从所述上钩臂上向上脱出，当所述脱扣器后退时所述第二滑出结合部结合着所述第一滑出结合部并通过所述第一滑出结合部能够带着所述自锁连接扣及所述滑块向后移动；
(e)当所述脱扣器带着所述自锁连接扣向后移动而让所述下钩臂后退移动到所述陷阱的上方时，所述下钩臂能够向下旋转伸入所述陷阱从而所述第一滑出结合部也随之下沉，下沉的所述第一滑出结合部能够避让后退的所述第二滑出结合部从而让所述第二滑出结合部越过所述第一滑出结合部继续向后移动，此后所述脱扣器能够脱离所述自锁连接扣。
其中，本发明中提及的前、后是指以滑轨的运动方向为基准确定的相对方向，滑轨安装在家具中后的内侧端也是所述家具滑轨缓冲器的前端，反之为后端或者说是尾端。滑轨中的中轨或内轨向内侧端移动时是收缩滑轨，也就是关闭抽屉，反之就是打开抽屉。本发明中提及的上、下也是一个相对的方位位置。
其中，所述上、下布置并相互插接连接在一起的滑块和底座，最主要定义了所述滑块与底座之间的相对位置关系以及相对连接关系，既然存在插接连接关系，为此它们之间就有一部分壁体或机构是穿插在一起的。其次，所述滑块与底座之间设置的限位器，主要用于限定它们之间轴向相对滑移脱开时的最大行程，为此所述限位器可以单边地设置在所述滑块或底座上，也可以配对地同时设置在所述滑块和底座上。
其中，所述复位弹簧与所述阻尼缓冲器是一对矛盾的组合体，所述阻尼缓冲器主要是为了缓冲所述复位弹簧的回弹力从而让所述滑块在所述底座上向内侧方向复位移动时不要力度过猛速度不要过快；所述阻尼缓冲器一般采用缓冲气缸、缓冲油缸或缓冲弹簧制造。
其中，所述自锁连接扣包括有前、后布置的第一转动结合部和下钩臂，主要定义了 第一转动结合部和下钩臂之间在所述自锁连接扣上的相对位置关系并且它们之间具有一定的间距从而所述下钩臂能够以所述第一转动结合部为力臂支点转动。
其中，所述下钩臂位于所述自锁连接扣的下部并钩向所述底座，主要定义了在总体上所述下钩臂在所述自锁连接扣上的相对位置以及能够钩向所述底座的功能和用途，同时也定义所述下钩臂的结构，其具有能够钩住所述底座从而锁定所述滑块制止其反向复位的结构。为此，所述下钩臂本身呈钩状结构并且折弯臂体的弯转方向是朝向所述底座的前端方向的。
其中，所述底座的尾端部上设置有能够避让所述下钩臂的陷阱以及能够结合所述下钩臂的钩臂结合部，主要定义了所述底座的尾端部的与所述下钩臂相结合的部位的结构；与所述下钩臂相结合的所述陷阱部位可以是凹坑状的结构，也可以是完全敞开的结构或通孔结构，只要能够让所述下钩臂进入其中即可，为此技术特征“避让”也即“收容”、“接纳”、或“让其进入”的同义词；与所述下钩臂相结合的钩臂结合部，实际上就是能够与所述下钩臂形成钩接连接的部位，让所述下钩臂伸入到所述陷阱时也能钩挂住它即可，例如位于所述陷阱周围的壁体特别是所述陷阱周围靠近前端方向的壁体。
其中，在所述自锁连接扣的脊背上前、后布置有上钩臂和第一滑出结合部，主要定义了所述上钩臂和第一滑出结合部在所述自锁连接扣上的设置位置以及所述上钩臂与第一滑出结合部之间在所述自锁连接扣上的相对位置关系，它们之间具有一定的间距，而且也定义了所述上钩臂也是一种具有能够实现钩街的结构。
其中，所述上钩臂具有插接结构从而让插接其上的物件不能向上脱出，主要定义了所述上钩臂与插接其上的物件例如下面将要提及的所述前叉臂如果连接在一起能够具有的连接结构，即如果所述上钩臂结合着所述下钩臂，所述上钩臂就不能向上脱出；实现该结构方式可以是在水平方向上的相互插接结构，也可以是斜面插接结构。
其中，所述第一滑出结合部位于所述下钩臂的上方，主要定义了所述第一滑出结合部与所述下钩臂之间在所述自锁连接扣上的相对位置关系，所述第一滑出结合部可以位于所述下钩臂的正上方，也可以在前后方向上稍微存在偏移。由于所述第一滑出结合部位于所述下钩臂的上方，为此当所述自锁连接扣转动而让所述下钩臂进入所述陷阱而下沉时，所述第一滑出结合部也能随之下沉移动并获得下沉行程，从而能够在让所述第一滑出结合部与所述第二滑出结合部之间在水平方向上具有较大范围交叉高度时又能形成避让所述第二滑出结合部的避让空间。
其中，所述脱扣器大致呈板状能够固定连接到滑轨，主要定义了所述脱扣器在总体上的形状是大致呈板状，而且也定义了所述脱扣器是能够固定连接到滑轨上的构件，所述脱扣器能够通过设置在所述脱扣器上的连接柄或设置在所述脱扣器上的安装孔结合铆钉类的连接件与所述滑轨形成固定连接，而所述连接柄是所述脱扣器上设置的可以与所述滑轨形成连接的连接部位。
其中，所述脱扣器包括有能够插接到所述上钩臂上的前叉臂，当所述脱扣器前行而所述前叉臂插接到所述上钩臂中时，所述前叉臂能够带着所述自锁连接扣及所述滑块前行但不能从所述上钩臂上向上脱出。首先主要定义了所述脱扣器的所述前叉臂能够插接到所述上钩臂上的功能和连接结构，所述前叉臂具有的插接到所述上钩臂上后不能向上脱出的结构，从而能够让安装在所述脱扣器上的所述内轨的内侧端不会翘起，在此基础上所述前叉臂还能牵引所述自锁连接扣向前移动。
其中，所述脱扣器包括有能够结合所述第一滑出结合部的第二滑出结合部，当所述脱扣器后退时所述第二滑出结合部结合着所述第一滑出结合部并通过所述第一滑出结合部能够带着所述自锁连接扣及所述滑块向后移动。该特征定义了所述第二滑出结合部与所述第一滑出结合部能够结合在一起的结构，而且定义了所述第二滑出结合部后退时能够牵引推动所述自锁连接扣后退的功能和结构。另外当所述脱扣器的所述前叉臂插接到所述上钩臂上并且所述第二滑出结合部结合着所述第一滑出结合部时，所述第一滑出结合部从后面顶抵住所述第二滑出结合部，从而所述第一滑出结合部又能限制住所述脱扣器不能容易地从所述上钩臂上向上脱出。
其中，下沉的所述第一滑出结合部能够避让所述第二滑出结合部从而让所述第二滑出结合部越过所述第一滑出结合部继续向后移动，此后所述脱扣器能够脱离所述自锁连接扣。该特征首先至少定义了所述第一滑出结合部与所述第二滑出结合部之间的相对衔接结构和在后退时的避让结构，它们之间可以是凹凸组合结构，也可以是相对凸出的凸出柱并前后排列的组合结构。其次，该特征还至少定义了所述前叉臂与所述上钩臂之间具有能够插接连接又能在后退时相对分离的连接结构。
既然下沉的所述第一滑出结合部能够避让所述第二滑出结合部，为此所述第一滑出结合部下沉的行程至少等于所述第一滑出结合部与所述第二滑出结合部之间在水平方向上前后交叉搭接的高度范围。
根据上述技术方案，(1)当所述内轨及连接其上的所述脱扣器在所述滑块或者说在 所述自锁连接扣的上方向前(内侧端)移动时，所述脱扣器的前叉臂能够插接到所述自锁连接扣的上钩臂上而不会向上脱开例如所述前叉臂的前端倾斜面结合到所述上钩臂所具有的折弯壁面的下面，并给予所述自锁连接扣向前移动的力矩从而让所述自锁连接扣稍微向上转动进而让所述下钩臂稍微向上翻转，也进而让所述下钩臂与所述底座之间脱扣，所述第二滑出结合部也结合所述第一滑出结合部，保证所述脱扣器既使在中间停止前进所述前叉臂也不会脱离所述上钩臂，此后所述复位弹簧能够带着所述滑块，所述滑块通过所述第一转动结合部和所述第二转动结合部带着所述自锁连接扣，所述自锁连接扣通过所述第一滑出结合部和所述第二滑出结合部带着所述脱扣器，所述脱扣器带着连接其上的内轨一并向前移动复位，其中所述阻尼缓冲器又能让所述复位弹簧的回弹速度得以缓冲。在所述前叉臂插入到所述上钩臂中的期间内，所述前叉臂不能从所述上钩臂中脱出，从而连接在所述脱扣器上的内轨的内侧端也就不能向上翘起，让所述内轨的内侧端始终贴合在所述中轨上，这样所述内轨与所述中轨之间的间隙就不会被加大从而大大提高了滑轨运行的稳定性。
(2)当所述内轨带着结合在所述自锁连接扣上的所述脱扣器向后移动时，所述第二滑出结合部向后挤推所述第一滑出结合部从而带动所述自锁连接扣及与其连接的所述滑块在所述底座上向后滑动，但当所述自锁连接扣的下钩臂后退移动到所述陷阱的上方时，所述下钩臂能够向下旋转伸入所述陷阱从而所述第一滑出结合部也随之下沉，下沉的所述第一滑出结合部能够避让所述第二滑出结合部从而让所述第二滑出结合部越过所述第一滑出结合部继续向后移动，此后所述脱扣器的前叉臂开始脱离所述自锁连接扣的上钩臂，并且所述第二滑出结合部还能在越过所述第一滑出结合部的同时进一步向下挤压所述第一滑出结合部，进而也进一步让所述下钩臂向下旋转伸入所述陷阱钩住所述钩臂结合部。随后所述内轨及其上的所述脱扣器完全与所述自锁连接扣脱离向外端移动。
进一步的技术方案还可以是，在所述底座上设置有开口朝上的轴向滑槽，所述自锁连接扣位于所述轴向滑槽的上方，所述自锁连接扣的下钩臂落入所述轴向滑槽并搁置在所述轴向滑槽的槽底壁上，所述陷阱设置在所述轴向滑槽的槽底壁之尾端位置，结合所述陷阱的所述槽底壁形成所述钩臂结合部。
其中，结合所述陷阱的所述槽底壁是指位于所述陷阱侧边位置的所述槽底壁，也指延伸到所述陷阱所在空间中的凸出壁体，总之是指让伸入到所述陷阱中的所述自锁连接扣的下钩臂能够钩挂的壁体。根据上述技术方案，通过所述轴向滑槽，不仅能够提高所述底 座的结构强度，而且也能引导和限定所述自锁连接扣及其上所述下钩臂的轴向移动轨迹，不会因受力而左右摆动。
进一步的技术方案还可以是，所述第二转动结合部是转轴，所述第一转动结合部是能够铰接在所述第二转动结合部上的叉口臂，所述第二转动结合部通过一对连接支架连接到所述滑块的头端部，所述第二转动结合部及一对所述连接支架位于所述轴向滑槽的上方或直接延伸到所述轴向滑槽中。这样能够借助于一对所述连接支架转动定位所述自锁连接扣。
进一步的技术方案还可以是，所述轴向滑槽上设置有能够限定一对所述连接支架轴向滑动行程的阻挡部，一对所述连接支架与所述阻挡部共同配对形成所述底座与所述滑块之间的用于限定它们之间相对最大滑离行程的限位器。
进一步的技术方案还可以是，在所述滑块上还设置有与所述轴向滑槽上、下对应的轴向走廊，所述自锁连接扣布置在所述轴向走廊中并且所述自锁连接扣的下钩臂从所述轴向走廊中延伸到所述轴向滑槽中。
进一步的技术方案还可以是，还包括形成所述轴向走廊的一对左、右布置的围栏体，一对所述围栏体的后端结合到所述滑块后端部的围栏结合部位，一对所述围栏体的顶端面高于所述围栏结合部位所在的上表面。这样能够让所述脱扣器向所述滑块的前端部方向移动进入所述滑块的上方时，至少设置在所述脱扣器下面的第二滑出结合部能够在一对所述围栏体所构成的所述轴向走廊中移动，而下面将要提及的所述侧边翼片确又能够滑动搭接在所述轴向走廊的围栏体上移动。这样不仅稳定而且也大大提高了所述滑块的结构强度，减小了整个所述家具滑轨缓冲器的厚度。
进一步的技术方案还可以是，所述脱扣器的上部还设置有侧边翼片，所述侧边翼片延展出所述轴向走廊的至少一个围栏体，当所述脱扣器在所述滑块的上方前后滑移时，所述侧边翼片滑动搭接在所述轴向走廊的围栏体上。
进一步的技术方案还可以是，在所述自锁连接扣的所述下钩臂与所述第一转动结合部之间还设置有侧向凸出柱，所述侧向凸出柱向与所述自锁连接扣的旋转平面相垂直的方向延伸，所述侧向凸出柱能够顶靠在所述围栏体的下面从而通过所述侧向凸出柱限制所述自锁连接扣向上翻转的角度。
进一步的技术方案还可以是，所述上钩臂具有折弯壁面，所述上钩臂的折弯壁面朝向与所述下钩臂的朝向相反配置，所述前叉臂的前端具有与所述上钩臂的折弯壁面适配的 倾斜面。其中，所述上钩臂的折弯壁面朝向与所述下钩臂的朝向相反配置，主要定义了所述上钩臂的折弯壁面的朝向，而且其朝向与所述下钩臂的折弯臂体的弯转方向是相反的，即所述上钩臂的折弯壁面是朝向所述底座的尾端方向
进一步的技术方案还可以是，所述自锁连接扣上的第一滑出结合部是向上凸起的上凸块，所述脱扣器上的第二滑出结合部是向下凸出的下凸块，所述自锁连接扣上的前、后布置的所述上钩臂与第一滑出结合部之间具有敞口朝上的上部空槽，当所述脱扣器沿所述自锁连接扣的上表面向前移动时，所述脱扣器的前叉臂及所述第二滑出结合部能够容纳在所述上部空槽中。
进一步的技术方案还可以是，所述脱扣器的所述前叉臂往下延伸形成延伸部，所述延伸部与所述第二滑出结合部之间设置有第一凹坑，所述第二滑出结合部的后面还设置有第二凹坑，所述自锁连接扣上的第一滑出结合部不仅能够插入到所述第二凹坑而且也能插入所述第一凹坑。
进一步的技术方案还可以是，在所述底座上还轴向设置有开口朝下的缓冲器容纳槽，所述缓冲器容纳槽相邻并平行于所述轴向滑槽，所述阻尼缓冲器的主体容纳在所述缓冲器容纳槽内，而所述阻尼缓冲器的输出轴的轴端连接在所述滑块的尾端部。这种相邻但槽口朝向相反的结构，不仅能够便利于安装其上的部件而且也能够在简化结构的同时却又大大提高了所述底座的机构强度。
进一步的技术方案还可以是，在所述滑块的左、右两边还设置有能够避让家具滑轨的侧壁体的轴向避让通道，所述自锁连接扣位于左、右设置的所述轴向避让通道之间的区域。
进一步的技术方案还可以是，还包括有横向缓冲片，所述横向缓冲片位于所述滑块尾端的轴向端部并且所述横向缓冲片的一个端部固定在所述滑块尾端而另一个端部是自由端。
进一步的技术方案还可以是，包括大致呈U型槽状的外轨、中轨和内轨，所述中轨轴向滑动设置在所述外轨的U型槽内并且所述中轨与所述外轨的槽口朝向相同，所述内轨轴向滑动设置在所述中轨的U型槽内并且所述中轨与所述内轨的槽口朝向相反；其特征在于，还包括有所述家具滑轨缓冲器，所述家具滑轨缓冲器的缓冲基座设置在所述外轨内侧端的U型槽内，所述脱扣器通过设置其上的所述连接柄连接到所述内轨内侧端的U型槽内。

具体实施方式
下面结合附图1到附图14对应用本发明的家具滑轨缓冲器及其所应用的家具滑轨的具体实施方式做进一步的说明。
如图1所示，本实施例设计的所述滑轨100包括大致呈U型槽状的外轨5、中轨6和内轨7，还包括家具滑轨缓冲器，所述家具滑轨缓冲器包括有设置在所述外轨5的内侧端的U型槽内的缓冲基座101及设置在所述内轨7内侧端的U型槽内的脱扣器3，所述脱扣器3包括有连接柄36，所述连接柄36上设置有连接孔30，通过所述连接柄36上的所述连接孔30结合铆钉连接所述内轨7内侧端U型槽的槽底壁上设置的安装孔70，将所述脱扣器3直接固定安装在所述内轨7内侧端U型槽的槽底壁上。所述中轨6轴向滑动设置在所述外轨5的U型槽内并且所述中轨6与所述外轨5的槽口朝向相同，所述内轨7轴向滑动设置在所述中轨6的U型槽内并且所述中轨6与所述内轨7的槽口朝向相反。
其中，本实施例中提及的前、后是指以滑轨的运动方向为基准确定的相对方向，滑轨安装在家具中后的内侧端也是所述家具滑轨缓冲器的前端，反之为后端或者说是尾端。滑轨中的所述中轨6或内轨7向内侧端移动时是收缩滑轨，也就是关闭抽屉，反之就是打开抽屉。本发明实施例中提及的上、下也是一个相对的方位位置，提到的轴向也是指滑轨或所述滑块的运动轨迹所在的方向。
如图2所示，所述缓冲基座101包括上、下布置并相互插接连接在一起的底座1和滑块2、连接在所述底座1与所述滑块2之间并位于两侧位置的复位弹簧(11、12)和能够对所述复位弹簧(11、12)的回弹力予以缓冲的阻尼缓冲器13、能够将所述底座1与所述滑块2予以锁定的自锁连接扣4；所述滑块2轴向滑动安装在所述底座1上，如图4、图5和图14所示所述底座1与所述滑块2之间还设置有能够限定它们之间相对滑离最大行程的限位器(190、290)。
所述复位弹簧(11、12)与所述阻尼缓冲器13是一对矛盾的组合体，所述阻尼缓冲器13主要是为了缓冲所述复位弹簧(11、12)的回弹力从而让所述滑块2在所述底座1上向内侧方向复位移动时不要力度过猛速度不要过快，从而不仅降低关闭的噪音而且也大大提高使用的舒适度和友好度，而所述阻尼缓冲器13采用缓冲气缸具有主体131及输出轴132，当然所述阻尼缓冲器13也可以采用缓冲油缸或缓冲弹簧制造。如图2所示，所述复位弹簧(11、12)的前端定位在所述底座1的定位座(110、120)上，所述复位弹簧(11、12)的尾端定位在所述滑块2的定位座(210、220)上。
下面对应用本发明的所述底座1、滑块2、脱扣器3以及所述自锁连接扣4的具体实施结构作进一步的分步说明。
第一，关于所述底座1。
所述底座1大致呈T型包括有轴向主体10，所述底座1通过设置在所述轴向主体10两侧的两侧翼边(181、182)插接在所述滑块2两侧设置在插接槽(281、282)内；事实上所述底座1与所述滑块2之间的相对插接连接结构还可以作其它安排，不是仅仅只有本实施例这一种实施结构。所述滑块2与底座1之间设置的限位器，主要用于限定它们之间轴向相对滑移脱开时的最大行程，为此所述限位器可以单边地设置在所述滑块2或底座1上，也可以如本实施例一样相互配对地同时设置在所述滑块2和底座1上。
如图2所示，在所述底座1上设置有开口朝下的缓冲器容纳槽14，所述阻尼缓冲器13的主体131容纳在所述缓冲器容纳槽14内，而所述阻尼缓冲器13的输出轴132的轴端 卡接连接在所述滑块2的尾端部的定位卡200上。这样当所述滑块2在所述底座1上回缩时所述阻尼缓冲器13能够形成回复缓冲力矩，降低所述滑块2的回复速度。
如图14所示，在所述底座1的所述缓冲器容纳槽14的槽壁140反面的尾端位置设置有形成所述限位器的其中一个挡块190，对应地在如图2、图3、图4和图5所示在所述滑块2上设置有另一个止挡290，所述挡块190与止挡290相对配对形成第一个限位器A。这样当所述滑块2轴向滑移出所述底座1时，所述止挡290能够被所述挡块190所阻挡从而限定了所述滑块2在所述底座1的最大滑出(滑离)行程。
如图3、图14所示，在所述底座1上轴向设置有开口朝上的轴向滑槽15，所述轴向滑槽15相邻并平行于所述缓冲器容纳槽14，但其开口朝向相反；这种相邻但槽口朝向相反的结构，不仅能够便利于安装其上的部件而且也能够在简化结构的同时却又大大提高了所述底座1的机构强度。
在所述底座1的尾端部设置有陷阱17，所述陷阱17也位于所述轴向滑槽15的末端(即在所述轴向滑槽15的末端去掉部分槽底壁150)而成为所述轴向滑槽15的槽底壁150上的一个避让窗口，结合所述陷阱的所述槽底壁150形成能够与所述下钩臂46形成连接的钩臂结合部151。
如图3、图14所示，所述轴向滑槽15的末端并位于所述陷阱17之前的所述槽底壁150上设置有能够限定如图5所示所述支架23轴向滑动行程的一对阻挡部(161、162)，一对所述阻挡部(161、162)之间还设置有过渡间隙160。所述支架23与一对所述阻挡部(161、162)之间共同配对形成所述底座1与所述滑块2之间的另一个限位器B。
如图3、图14所示，在所述底座1前端部的横向主体上还设置有底座安装孔18，所述底座1通过所述底座安装孔18及铆钉等连接件固定连接到所述外轨5的内侧端的U型槽内。
第二，关于所述滑块2。
所述滑块2在整体上大致呈板状，如图2、图3所示，在其尾端的轴向端部设置有横向缓冲片21，所述横向缓冲片21的一个端部固定在所述滑块2的尾端而另一个端部是自由端。这样当收缩所述中轨6时所述中轨6的内侧端能够顶靠在所述横向缓冲片21上从而对其形成缓冲。
如图4所示，在所述滑块2的左、右两边还设置有能够避让所述内轨7的侧壁体的轴向避让通道(291、292)，所述自锁连接扣4位于左、右设置的所述轴向避让通道(291、 292)之间的区域。也即所述内轨7向内收缩滑行时，其槽底壁是位于所述滑块2的上方但其两侧侧壁是插入到所述通道(291、292)中。
如图3、图4和图5所示，在所述滑块2上还设置有与所述底座1上的所述轴向滑槽15上、下对应的轴向走廊27，所述轴向走廊27在上下方向上上下贯通，还包括形成所述轴向走廊27的一对左、右布置的围栏体(25、26)，一对所述围栏体(25、26)的后端结合到所述滑块2后端部的围栏结合部位28，一对所述围栏体(25、26)的顶端面(250、260)高于所述围栏结合部位28所在的上表面，这样便于所述脱扣器3从后往前滑入所述轴向走廊27，特别是能够让所述脱扣器3的下滑面能够滑动搭接在一对所述围栏体(25、26)的顶端面(250、260)上但位于所述脱扣器3下方的所述前叉臂31、第二滑出结合部33能够在所述轴向走廊27中穿行。其次所述止挡290也设置在靠近所述缓冲器容纳槽14的所述围栏体25的尾端位置。
当所述滑块2插接到所述底座1上时，所述底座1上的所述缓冲器容纳槽14位于所述围栏体25的侧边，并且所述轴向避让通道292位于所述缓冲器容纳槽14的槽底壁140的外侧边。
如图2、图5所示，一对所述围栏体(25、26)的前端部上设置有与所述第一转动结合部41能够铰接的转轴24，所述转轴24通过支架23连接到所述滑块2，所述支架23包括一对左右布置的连接支架(231、232)。当所述滑块2插接到所述底座1上时，所述转轴24及支架23伸入到所述轴向滑槽15中，并且当所述滑块2在所述底座1上滑出时，所述转轴24及支架23能够在所述轴向滑槽15中滑动，并且当滑动到末端时顶靠在一对阻挡部(161、162)上，从而也能够限定所述滑块2的最大轴向滑离行程。
第三，关于自锁连接扣4。
如图6和图7所示，所述自锁连接扣4包括有前、后布置的第一转动结合部41和下钩臂46，如图5所示，所述第二转动结合部24是转轴，所述第一转动结合部41是能够铰接在所述转轴24上的叉口臂从而具有叉口410，所述自锁连接扣4通过所述第一转动结合部41上的叉口410转动连接到所述转轴24上，这样能够借助于所述支架23转动定位所述自锁连接扣4；所述自锁连接扣4的转动轨迹平面大致垂直于所述滑块2的上表面。所述下钩臂46的顶端呈圆锥型并位于所述自锁连接扣4的下部并能够钩向所述底座1，其中，所述下钩臂46位于所述自锁连接扣4的下部并钩向所述底座1，主要定义了在总体上所述下钩臂46在所述自锁连接扣4上的相对位置以及能够钩向所述底座1的功能和用途， 同时也定义所述下钩臂46的结构，其具有能够钩住所述底座1从而锁定所述滑块2制止其反向复位的结构。为此，所述下钩臂46本身呈钩状结构并且折弯臂体的弯转方向是朝向所述底座1的前端方向的。
当所述底座1和滑块2相互插接连接在一起时，所述转轴24及所述支架23伸入到设置在所述底座1上的所述轴向滑槽15中，所述自锁连接扣4位于所述轴向滑槽15的上方，所述自锁连接扣4的下钩臂46从所述轴向走廊27中延伸到所述轴向滑槽15中并搁置在所述轴向滑槽15的槽底壁150上(图13所示的槽底壁150是图14所示槽底壁150的反面)。当所述滑块2在所述底座1上向后滑出时达到最大行程位置前，所述下钩臂46的顶端尖部首先滑过设置在一对阻挡部(161、162)之间的所述过渡间隙160，再达到所述陷阱17位置，所述下钩臂46能够向下旋转伸入所述陷阱17并钩住所述钩臂结合部151进而能够锁定所述滑块2制止其反向复位。
在所述自锁连接扣4的脊背上前、后布置有上钩臂43和第一滑出结合部45，所述上钩臂43具有倾斜的折弯壁面430，所述折弯壁面430的朝向与所述下钩臂46的朝向相反配置，所述第一滑出结合部45位于所述下钩臂46的上方，而所述上钩臂43位于所述第一转动结合部41的上方。所述上钩臂43的折弯壁面430朝向与所述下钩臂46的朝向相反配置，主要定义了所述上钩臂43的折弯壁面430的朝向，而且其朝向与所述下钩臂46的折弯臂体的弯转方向是相反的，所述上钩臂43的折弯壁面430是朝向所述底座1的尾端方向。通过所述折弯壁面430的配置，所述上钩臂43能够结合所述脱扣器3的前叉臂31让其不能向上脱出。当然为了实现不要向上脱出的功能，还可以将所述上钩臂43与所述前叉臂31之间设置为相互在水平方向上能够插接的结构。
如图6、图7所示，在所述自锁连接扣4的所述下钩臂46与所述第一转动结合部41之间还设置有侧向凸出柱42，所述侧向凸出柱42向与所述自锁连接扣4的旋转平面相垂直的方向延伸并且延伸的宽度大于一对所述围栏体(25、26)之间的宽度，如图11所示，当所述第一转动结合部41钩挂到所述第二转动结合部24上时，一对所述侧向凸出柱42位于一对所述围栏体(25、26)的下方从而能够分别顶靠在所述滑块2的一对围栏体(25、26)的下面从而通过所述侧向凸出柱42限制所述自锁连接扣4及其所述下钩臂46绕所述转轴24在所述轴向走廊27中向上(图11中的右向为向上方向)翻转的角度(或者说翻转的幅度)。
在本实施例中，如图6、图7所示，所述自锁连接扣4上的第一滑出结合45设置为 向上凸起的上凸块，所述上钩臂43和第一滑出结合部45之间具有敞口朝上的上部空槽44，所述上部空槽44用于活动结合所述脱扣器3，如图11所示，当所述脱扣器3沿所述自锁连接扣4的上表面向前(A向)移动时，所述脱扣器3的前叉臂31及呈下凸状的所述第二滑出结合部33能够伸入到所述上部空槽44中，所述第二滑出结合部33位于第一滑出结合部45的前面。当然为了实现脱扣功能，等同的方案还可以是，所述第一滑出结合部45还可以设置为凹槽状的凹槽，当然所述脱扣器3上所述第二滑出结合部33也就对应地设置为能够伸入所述凹槽的下凸块。
第四，关于脱扣器3。
如图2、图8、图9和图10所示，所述脱扣器3大致呈板状能够固定连接到内轨7。所述脱扣器3包括有能够插入到所述上钩臂43中的前叉臂31和能够结合所述第一滑出结合部45的第二滑出结合部33，所述前叉臂31的前端具有与所述上钩臂43适配的倾斜面311，所述第二滑出结合部33呈下凸状能够伸入到所述第一滑出结合部45的前面，即所述第二滑出结合部33与所述第一滑出结合部45是相对凸出的凸出柱并前后排列的组合结构。
其中，所述前叉臂31的前端面311呈与所述上钩臂43的折弯壁面430适配的斜面状，这样当所述脱扣器3的前叉臂插入到所述自锁连接扣4的上钩臂43中时，所述第一滑出结合部45结合在所述第二滑出结合部33的后方，限制了所述第二滑出结合部33后退的空间，让所述脱扣器3难以后退脱出所述上钩臂43，而所述前叉臂31能够借助于两个斜面的配合让它们之间不能在上、下方向上分离，不能从所述自锁连接扣4的上钩臂43上向上脱出，进而连接其上的所述内轨7的内侧端也就不能随意翘起。
如图8所示，所述前叉臂31及所述第二滑出结合部33在水平方向上的宽度W小于一对所述围栏体(25、26)之间的宽度，从而让所述前叉臂31及所述第二滑出结合部33能够在所述轴向走廊27中轴向移动。
如图10所示，所述脱扣器3的所述前叉臂31往下延伸形成延伸部312，所述延伸部312与所述第二滑出结合部33之间设置有第一凹坑32，所述第二滑出结合部33的后面还设置有第二凹坑34。在应用中，如图11所示，当所述脱扣器3的前叉臂31插入到所述自锁连接扣4的上钩臂43中时，实际上是所述第一滑出结合部45是插入到所述第二凹坑34中，这样当所述脱扣器3后退时，所述第二滑出结合部33在所述第一滑出结合部45的前方挤推所述第一滑出结合部45从而让所述自锁连接扣4以及连接其上的所述滑块2也 一并后退，如果因所述第二滑出结合部33破裂、因跳动而越过等原因导致所述第二滑出结合部33的挤推动作失灵，所述第一滑出结合部45顺次滑入所述第一凹坑32中，让所述延伸部312接着继续往后挤推所述第一滑出结合部45进而继续推动所述自锁连接扣4以及结合其上的所述滑块2向后移动。
如图12所示，当所述脱扣器3带着所述自锁连接扣4以及连接其上的所述滑块2一并后退(图中的B向)并且当所述下钩臂46后退移动到所述陷阱17的上方时，所述下钩臂46向下旋转(图中的C向)伸入所述陷阱17并钩住所述钩臂结合部151，所述第一滑出结合部45也随之下沉，下沉的所述第一滑出结合部45逐渐为所述第二滑出结合部33腾出后移的避让空间，此时所述第二滑出结合部33一边越过所述第一滑出结合部45一边进一步向下挤压所述第一滑出结合部45，促使所述下钩臂46向下旋转伸入所述陷阱17。随后所述脱扣器3的前叉臂31开始脱离所述自锁连接扣4的上钩臂43，所述内轨7及其上的所述脱扣器3完全与所述自锁连接扣4脱离向外端移动。为了让所述第二滑出结合部33能够平滑地向下挤压所述第一滑出结合部45，最好是将它们之间的结合面的顶端过渡部位设置为圆角，就像齿轮的轮齿顶部结构一样。
所述脱扣器3的上部还设置有侧边翼片35，所述侧边翼片35向左延展出所述轴向走廊27的左侧围栏体25，并让所述侧边翼片35高于所述前叉臂31及所述第二滑出结合部33，这样当所述脱扣器3在所述滑块2的上方前后滑移时，让所述前叉臂31及所述第二滑出结合部33在一对所述围栏体(25、26)中移动，而所述侧边翼片35下表面滑动搭接在所述轴向走廊27的左侧围栏体25上。当然所述脱扣器3的上部还设置有侧边翼片35还可以向右边延伸，也可以向两边同时延伸。
根据上述技术方案，(1)脱扣动作过程：当所述内轨7及连接其上的所述脱扣器3在所述滑块2或者说在所述自锁连接扣4的上方向前(内侧端)移动时，所述脱扣器3的前叉臂31能够插接到所述自锁连接扣4的上钩臂43上，所述前叉臂31的前端倾斜面311结合到所述上钩臂43所具有的折弯壁面430的下面，并给予所述自锁连接扣4向前移动的力矩从而让所述自锁连接扣4稍微向上翻转并让所述下钩臂46与所述底座1之间脱扣，此时所述第二滑出结合部33也结合在所述第一滑出结合部45的前方，所述第一滑出结合部45是插入到所述第二凹坑34中，保证所述脱扣器3既使在中间停止前进所述前叉臂31也不会脱离所述上钩臂43；脱扣后所述复位弹簧(11、12)能够带着所述滑块2，所述滑块2通过所述第一转动结合部41和所述第二转动结合部24带着所述自锁连接扣4，所述 自锁连接扣4通过所述第一滑出结合部45和所述第二滑出结合部33带着所述脱扣器3，所述脱扣器3带着连接其上的内轨7一并向前移动自动复位，其中所述阻尼缓冲器13又能让所述复位弹簧(11、12)的回弹速度得以缓冲。在所述前叉臂31插入到所述上钩臂43中的期间内，所述前叉臂31不能从所述上钩臂43中向上脱出，从而连接在所述脱扣器3上的内轨7的内侧端也就不能向上翘起，让所述内轨7的内侧端始终贴合在所述中轨6上，这样所述内轨7与所述中轨6之间的间隙就不会被加大从而大大提高了滑轨100运行的稳定性。
(2)上扣动作过程：当所述内轨7带着结合在所述自锁连接扣4上的所述脱扣器3向后移动时，由于所述第一滑出结合部45是插入到所述第二凹坑34中，所述第二滑出结合部33向后挤推所述第一滑出结合部45从而带动所述自锁连接扣4及与其连接的所述滑块2在所述底座1上向后滑动，但当所述自锁连接扣4的下钩臂46后退移动到所述陷阱17的上方时，因所述下钩臂46能够向下旋转伸入所述陷阱17从而所述第一滑出结合部45也随之下沉，下沉的所述第一滑出结合部45能够避让所述第二滑出结合部33从而让所述第二滑出结合部33越过所述第一滑出结合部45继续向后移动，此时所述脱扣器3的前叉臂31开始脱离所述自锁连接扣4的上钩臂43，并且所述第二滑出结合部33还能在越过所述第一滑出结合部45的同时进一步向下挤压所述第一滑出结合部45，进而也进一步让所述下钩臂46向下旋转伸入所述陷阱17钩住所述钩臂结合部151。随后所述内轨7及其上的所述脱扣器3完全与所述自锁连接扣4脱离向外端移动。在所述内轨7及其上的所述脱扣器3再次向内侧移动时，由于所述下钩臂46已经旋转伸入所述陷阱17钩住了所述钩臂结合部151，所述第一滑出结合部45也处于下沉位置而能够避让所述第二滑出结合部33，为此所述脱扣器3能够再次以水平方向前进直接插入到所述自锁连接扣4上开始脱扣的进程。
