一种连接件、连接组件、连接系统、安装工具及安装系统 技术领域
本发明涉及一种连接件，用于二合一、三合一家具五金连接件；本发明还涉及一种连接组件及连接系统，用于连接第一构件和第二构件，特别用于连接家具板件；本发明还涉及一种安装工具及安装系统，用于将连接件安装至第一构件内，特别用于将连接件安装于家具板件内。

目前，随着人们的审美观念不断提高，两个家具板件之间逐渐采用隐形连接件实现隐形式连接，从而提高家具的美观性，其中，二合一或三合一或四合一连接件广泛应用于两个家具板件之间的连接。但是，使用现有二合一或三合一连接件时用于安装偏心轮的板件开孔直径较大(通常需要大于等于7mm)，或者，使用现有四合一连接件时用于安装销件的板件开孔直径较大，用户容易通过较大的孔径观察到偏心轮或销件，从而导致二合一或三合一或四合一连接件的隐形性较低，影响了家具的美观性。
为此，中国专利公告号为CN213954095公开了《连接件》，将第一螺帽和至少部分螺钉件固定于第一板材的内部，至少部分螺钉件和第二螺帽位于第二板材的内部，通过球形扭件卡合于第二螺帽内的螺钉件，从而使两个板材稳定拼接。其中，球形扭件可以预先安装在第二螺帽内并随第二螺帽一起插入第二板材的内部，如此避免了球形扭件通过板材上的开孔插入板材的内部，使得板材上的开孔直径供工具(例如螺丝刀或内六角扳手)穿过以驱动球形扭件转动即可，大大减小了板材上的开孔直径，提高美观性。
进一步地，上述《连接件》的第二螺帽的外侧表面是螺旋纹状，第二螺帽通过转动的方式旋入第二板材的内部。但是，由于第二板材上的 开口部存在一定位置误差，导致第二螺帽安装至第二板材的内部后，位于第二螺帽内的球形扭件的中心轴线容易与第二板材的开口部的中心轴线不位于同一直线、或球形扭件的的第三凹陷部没有对准第二板材的开口部，需要再次转动第二螺帽来调整球形扭件的位置。但是，转动第二螺帽的过程中，第二螺帽会同时沿其周向和轴向两个方向上进行位置调整，导致球形扭件同时在第二螺帽的周向和轴向的两个方向上也发生变化，难以保证球形扭件的中心轴线与第二板材的开口部的中心轴线位于同一直线，调整难度较大，影响装配效率。

所述避让凹部靠近所述连接通道的开口设置。基于该实施例的技术方案，避让凹部的位置与第一构件的用于预埋灯带或电线的嵌装槽的位置相对应，避免连接件的靠近连接通道的开口一端会对第一构件的具有嵌装槽部分造成损坏或裸露出来。
此外，本发明第二方面提供了一种连接组件，用于连接第一构件和第二构件，所述连接组件包括偏心轮及如上面本发明第一方面所述的连接件，所述偏心轮可转动地安装于所述安装孔内。

实施例1
如图1-图28所示，本实施例1提供了一种连接件1，连接件1用于与连接杆4及偏心轮3配合使用以实现第一构件10与第二构件20连接。第一构件10的一侧形成有横截面为圆形状的安装通道101，安装通道101可以是通过钻孔工艺在第一构件10的侧面一次性加工而成，加工简单快捷有效率，安装通道101具体为圆柱体结构。连接件1为塑料件，例如通过注塑成型工艺制备而成。连接件1包括连接件主体，连接件主体的横截面的外轮廓与安装通道101的横截面相适配，具体连接件主体可以为圆柱体或圆台体或类圆柱体结构，其中类圆柱体结构可以是连接件主体的横截面外轮廓为椭圆形或梅花形或多角星形状。连接件主体的一端端部形成有沿连接件主体的轴向延伸的连接通道11，连接件主体的顶部外侧上形成有与连接通道11相连通的安装孔12，安装孔12用于安装偏心轮3，连接通道11的横截面包括操作截面14，连接通道11的具有操作截面14的部分用于与操作工具2配合以驱动连接件1沿连接件主体的中心轴线15转动；连接件主体的左右两外侧上分别形成有至少一个紧固倒牙13，紧固倒牙13用于将连接件主体限制在安装通道101内，紧固倒牙13用于当操作工具2驱动连接件1绕连接件主体的中心轴线15转动时，连接件1不能沿连接件主体的轴向移动。
其中，本实施例1的连接杆4及偏心轮3可以为现有二合一或三合一连接件的连接杆4及偏心轮3，也可以为中国专利公告号为CN114321115A公开的《一种第一连接件、连接组件及连接系统》中的第一连接件及第二连接件。本实施例1的偏心轮3先预装在连接件1的安装孔12内，偏心轮3与连接件1从第一构件10的一侧安装至第一构件10的内部，采用螺丝刀等工具穿过第一构件10的顶部或底部以控制偏心轮3的工作状态，从而使第一构件10与第二构件20相互连接或相互分开。由 于偏心轮3不需要从第一构件10的顶部或底部安装至第一构件10的内部，使得第一构件10上的开孔直径只需要供螺丝刀等工具穿过即可，极大地提高了偏心轮3在第一构件10上的隐形性。
进一步地，本实施例1的安装孔12的直径尺寸根据偏心轮3的直径尺寸适配性设计，安装孔12的直径尺寸略大于偏心轮3的直径尺寸，以使偏心轮3能够在安装孔12内发生转动。
如图17-图20所示，为了使偏心轮3通过本实施例1的连接件1安装至第一构件10的内部，需要先在第一构件10上与第二构件20相连接的一侧开设有安装通道101，具体采用钻孔工艺(如六面钻等)在第一构件10的侧壁上加工而成，安装通道101的横截面形状可以与连接件主体的横截面形状相同(即安装通道101的横截面形状为圆形)，也可以与连接件主体的横截面形状相似或相适配(例如安装通道101的横截面为椭圆形或腰圆形或由多段曲线拼接而成)。进一步地，安装通道101通常优选为圆柱形槽孔，为了使连接件1通过紧固倒牙13紧固在安装通道101内，紧固倒牙13最外侧边缘所在的外周圆的直径尺寸大于安装通道101的直径尺寸，以使连接件1插入安装通道101的过程中，安装通道101的内侧壁抵顶至紧固倒牙13以使紧固倒牙13发生弹性形变，产生形变张力，从而增大了连接件1在安装通道101内的滑动摩擦力，通过紧固倒牙13将连接件主体限制在安装通道101内，以使连接件1稳固在第一构件10的内部。此外，通过钻孔方式在第一构件10的顶部或底部加工有与安装通道101相连通的连接孔102(连接孔102的孔径只需要供螺丝刀或扳手等工具穿过即可)，当连接件1插入安装通道101后并使安装孔12的位置与连接孔102的位置相对应并相连通，采用螺丝刀等工具穿过连接孔102后驱动偏心轮3转动。
进一步地，本发明的连接件1的左右方向为连接件1插入第一构件10的安装通道101后，使用者面对连接件1时的左右方向。在一些具体的应用场景中，如图17-图20所示，第一构件10为层板，第二构件20为柜体的侧板，左右方向为层板的长度方向或宽度方向，上下方向为层板的 厚度方向。
进一步可以理解的是，本实施例1的连接件1采用PP或PE或PET或PVC或POM等材料通过注塑工艺制备而成，成型后的连接件1具有一定的硬度，但硬质塑料材质的连接件1也能够具有一定的弹性形变能力，当连接件1的具有紧固倒牙13部分在插入安装通道101的过程中，由于塑料材质的紧固倒牙13与安装通道101的内侧壁相互抵顶后会产生弹性形变，从而使连接件1紧固在第一构件10的内部，难以从安装通道101内拔出。在连接件1安装至安装通道101后，当安装孔12的中心轴线与第一构件10的连接孔102的中心轴线不在同一直线上时，采用操作工具2插入连接通道11的具有操作截面14的部分以驱动连接件1沿连接件主体的周向转动一定角度、或者采用工具推动连接件1沿连接件主体的轴向移动一定距离，当连接件1在安装通道101内转动时，通过紧固倒牙13保证连接件1在安装通道101内转动的过程中只沿连接件主体的周向发生移动，确保连接件1在调整过程中只沿一个方向上发生移动，从而使安装孔12的中心轴线与连接孔102的中心轴线调整至同一直线或接近同一直线上，便于工具(例如螺丝刀或扳手)驱动安装孔12内的偏心轮3转动，操作简单且效率高，确保装配效率。
其中，如图2-图3所示，紧固倒牙13具有预设平面131及引导面132，沿连接通道11的开口的一端往另一端的方向上，预设平面131与引导面132依次设置。引导面131用于使连接件1顺利插入安装通道101内，预设平面131可以不是连接件1从外观上观察到的平面，而是一个虚拟的内部平面，预设平面131的存在是用来描述紧固倒牙13不同于旋转螺旋纹状，或，不同于旋转螺旋纹状片段或组合，以对紧固倒牙13进行功能性限定。在一些实施方式中，预设平面131与引导面132相连接的位置处所形成的外周圆与连接件主体的中心轴线15相互垂直，使得当操作工具2驱动连接件1绕连接件主体的中心轴线转动时，连接件1不能沿连接件主体的轴向移动。进一步地，本实施例1的操作工具2的至少一部分的横 截面形状与操作截面14的形状相同或相似，用于保证操作工具2能够顺利插入连接通道11内，通常情况下，操作工具2插入连接通道11的部分的横截面形状相同。连接通道11的全部横截面可以与操作截面14形状相同，也可以是一部分截面与操作截面14形状相同(操作截面14优选为靠近连接通道11开口的部分)，另一部分为圆形。
如图23-图28所示，操作工具2可以为现有常用的标准工具，如内六角扳手或多角星形扳手或花瓣形扳手或梅花形扳手或其他横截面为多边形状的柱状体等，操作截面14的形状与操作工具2的横截面相同或相近。在一些具体的使用场景中，卖家或制造商只生产或销售连接件1，当连接件1的操作截面14适配于标准的工具，如六角扳手或多角星形扳手或花瓣形扳手或梅花形扳手或其他横截面为多边形状的柱状体等等，也落入本专利的保护范围。
在一些实施方式中，如图26-图28所示，设定连接件主体的径向包括相互垂直的X轴方向和Y轴方向，X轴方向沿左右方向延伸，Y轴方向沿上下方向延伸，操作工具2沿X轴方向的外侧壁与操作截面14沿X轴方向的边线之间的距离D1为0.025-1.5mm，操作工具2沿Y轴方向的外侧壁与操作截面14沿Y轴方向的边线之间的距离D2为0.005-0.5mm，且D1大于D2。当连接件1滑动插入第一构件10的安装通道101的过程中，安装通道101的内侧壁抵顶紧固倒牙13以使紧固倒牙13发生弹性形变，同时使连接件主体的左右两侧也发生变形，导致连接通道11的左右两内侧壁也发生微量变形，缩小了操作截面14的左右两侧缘之间的距离，使得D1与D2相等或接近相等，以使操作工具2顺利插入连接通道的具有操作截面14的部分并保证操作工具2的外侧壁与操作截面14之间的距离较小，满足操作工具2驱动连接件1在安装通道101内沿周向转动的间距要求，从而调整连接件1在安装通道101的位置以使安装孔12的中心轴线与第一构件10上的连接孔102的中心轴线位于同一直线或接近同一直线上，便于工具(例如螺丝刀或扳手)驱动安装孔12内的偏心轮3转动，操作简单且效率高，避 免了安装孔12与连接孔102的位置不相对应的麻烦，确保装配效率。
在一些实施方式中，如图27、图28所示，操作截面14的形状为六边形，操作截面14包括第一预设边线141、第二预设边线142、两个第三预设边线143及两个第四预设边线144，第一预设边线141靠近连接件主体的顶部并沿X轴方向延伸；第二预设边线142靠近连接件主体的底部并沿X轴方向延伸；两个第三预设边线143分别靠近连接件主体的左侧并呈夹角设置；两个第四预设边线144分别靠近连接件主体的右侧并呈夹角设置；第一预设边线141、第二预设边线142、两个第三预设边线143及两个第四预设边线144共同围合形成操作截面14的外侧边缘。其中，两个第三预设边线143分别一一对应与两个第四预设边线144相互平行，操作工具2沿X轴方向的外侧壁与两个第四预设边线144的交点的距离为D1，操作工具2沿Y轴方向的外侧壁与第一预设边线141的距离为D2。其中，两个第三预设边线143之间的夹角为120°或接近120°，两个第四预设边线144之间的夹角为120°或接近120°。相应地，本实施方式的操作工具2的至少一部分的横截面形状为六边形，具体可以为现有技术中通用的内六角扳手。
如图28所示，进一步设定第一预设边线141的长度为L1、第二预设边线142的长度为L2、第三预设边线143的长度为L3及第四预设边线144的长度为L4,为了保证D1大于D2，L1、L2均大于L3和L4，进一步为了使操作截面14适配现有通用的内六角扳手(内六角扳手的横截面为正六边形状)，可以使L1＝L2或L1≈L2，L3＝L4或L3≈L4。当连接件11插入安装通道101后，安装通道101的内侧壁抵顶紧固倒牙13以使紧固倒牙13发生弹性形变，从而使连接件主体的具有紧固倒牙13部分也发生变形，进而导致连接通道11的内侧壁发生微量变形，缩小L3与L4之间的距离，即L1与L2的长度缩短了，并使得L1＝L2＝L3＝L4或L1≈L2≈L3≈L4，此时连接通道11的横截面为正六边形状或接近正六边形状，以使内六角扳手顺利插入连接通道11的操作截面14部分并能够轻松带动连接件11在安装通道101内发生转动，调整连接件11在安装通道101的位置以使安 装孔12的中心轴线与第一构件10上的连接孔102的中心轴线位于同一直线或接近同一直线上，操作简单且效率高。
进一步地，第一预设边线141的长度L1(或第二预设边线142的长度L2)与第三预设边线143的长度L3(或第四预设边线144的长度L4)之间可以满足：0.2mm≤L1-L3≤1mm(或0.2mm≤L1-L4≤1mm)，如此控制L1、L2、L3及L4之间的尺寸差，保证连接通道11发生变形后L1＝L3或L1≈L3，从而使操作截面14呈正六边形状或接近正六边形状。第三预设边线143的长度L3根据现有通用的内六角扳手的尺寸适配性设计，L3的取值范围为2mm≤L3≤8mm。
在另外一些实施方式中，如图24、图25所示，操作截面14的形状为多边形或梅花形或花瓣形或多角星形。其中多边形状包括三角形、四边形、五边形等形状，相应地，操作工具2的横截面也呈三角形、四边形、五边形等形状。当操作截面14呈梅花形或花瓣形或多角星形时，操作工具2的横截面也呈梅花形或花瓣形或多角星形。
在一些实施方式中，紧固倒牙13设于连接件主体的左外侧和/或右外侧。当第一构件为层板(层板的厚度通常为18mm或16mm等)时，由于第一构件10在安装通道101上下两侧的厚度较小，为了避免连接件1在插入安装通道101的过程中紧固倒牙13对第一构件10的上侧或下侧造成胀起或凸起，将紧固倒牙13设在连接件主体的左外侧和/或右外侧能够保证紧固倒牙13对第一构件1的抵顶力的方向是朝向左侧或右侧，提高连接件1安装后的第一构件的美观性。本发明并不限定位于连接件主体左侧或右侧的紧固倒牙13的数量，位于连接件主体左右两侧的紧固倒牙13数量可以相同或不相同，例如位于左侧的紧固倒牙13数量大于位于右侧的紧固倒牙13数量，或者又例如左侧的紧固倒牙13数量等于位于右侧的紧固倒牙13数量。在一些实施方式中，如图1-图7所示，连接件主体的左右两外侧上分别形成有多个紧固倒牙13，位于连接件主体左侧或右侧的多个紧固倒牙13沿连接件主体的轴向依次间隔设置。本实施方式的各紧固倒牙13沿连接件主体的周向 连续延伸，以使紧固倒牙13呈连续的弧形长条体状，如此紧固倒牙13与安装通道101内侧壁之间的接触面积较大，提高连接件1在安装通道101内的紧固效果。同时，当操作工具2驱动连接件1在安装通道101内转动时，各连续的紧固倒牙13与安装通道101内侧壁之间的受力轨迹是连续且均匀，有利于提高连接件1在安装通道101内转动的稳定性。
在另外一些实施方式中，如图8-图14所示，连接件主体的左右两外侧上分别形成有多个紧固倒牙13，位于连接件主体左侧或右侧的多个紧固倒牙13呈零星状间隔设置。具体地，紧固倒牙13呈凸点或凸块状等，位于连接件主体左侧或右侧的多个紧固倒牙13可以呈有规律分布，例如一部分紧固倒牙13沿连接件主体的周向间隔分布的同时，一部分紧固倒牙13沿连接件主体的轴向间隔分布，例如呈矩阵形式分布；或者连接件主体左侧或右侧的多个紧固倒牙13可以呈无规律分布，从而使多个紧固倒牙13分布于连接件主体的左侧或右侧。如此多个紧固倒牙13呈零星状间隔设置能够使连接件1在安装通道101内的紧固力是呈不均匀分布或多点分布，有利于提高连接件1在安装通道101内的紧固效果。
在一些实施方式中，多个紧固倒牙13靠近连接通道11的开口的一端设置。如此连接件1在滑动插入安装通道101的过程中，由于紧固倒牙13与安装通道101内侧壁的接触行程较短，减小连接件1插入安装通道101的装配阻力，使得连接件1在第一构件10上的安装较为省力轻松，提高安装效率。
进一步地，引导面132为弧形面或倾斜平面或球形面，当引导面132为倾斜平面，引导面132与预设平面131之间形成的夹角为锐角，此时紧固倒牙13呈倾斜的三角形体状；再例如图13所示，引导面132为球形面，此时紧固倒牙13呈半球体状或类球体状。由于连接件1是沿连接件主体的具有连接通道11开口的一端往另一端的方向插入安装通道101，通过引导面132减小连接件1在插入过程中与安装通道101 内侧壁之间的接触面面积，从而减小连接件1移动的摩擦力，提高连接件1插入安装通道101的顺畅性及便捷性。
在一些实施方式中，当第一构件10为柜体的层板时，第一构件10的厚度尺寸较小(通常厚度为16mm以下)，为了避免第一构件10在运输或使用过程中出现损坏，第一构件10在安装通道101的顶部或底部部分应当具有足够的厚度，为此，位于连接件主体左右两侧的紧固倒牙13形成的外接圆的直径尺寸为9-15mm，例如9mm、10mm、10.5mm、12mm、15mm等，此时呈圆形的安装通道101的直径尺寸为9-15mm，从而保证第一构件10在安装通道101的顶部及底部的厚度均大于0.5mm，有效保证第一构件10的结构强度及稳定性，同时也避免连接件1在插入安装通道101的过程中对第一构件10造成损坏。
在一些实施方式中，如图18-图20所示，当第一构件10的顶部或底部安装有电器时，通常需要在第一构件10的顶部或底部的边缘位置或中间位置加工有嵌装槽103，嵌装槽103用于预埋灯带或让布置在嵌装槽103中的电线(电线可以是连接灯带或电器)，达到美观化效果。但是，当厚度较薄的第一构件10的顶部或底部加工有嵌装槽103时，嵌装槽103会进一步降低了第一构件10的边缘位置的厚度，导致当连接件1插入第一构件10的安装通道101后，连接件1的靠近连接通道11的开口一端会对第一构件10的具有嵌装槽103部分造成损坏或导致连接件1裸露出来，降低美观性。或者，在连接件1插入第一构件10后再加工有嵌装槽103时，会对连接件1的靠近连接通道11的开口一端造成损坏。为此，如图1-图14所示，连接件主体的顶部外侧和/或底部外侧上形成有避让凹部16，避让凹部16靠近连接通道11的开口设置，避让凹部16的深度可以是根据嵌装槽103的槽深适应性设计，例如避让凹部16的深度为0.1-1.5mm，避让凹部16的宽度与嵌装槽103的槽宽相同或接近相同，例如避让凹部16的宽度为0.1-3.0mm，以使连接件1插入安装通道101后，避让凹部16的位置刚好移动至嵌装槽103的位置。其中，连接件主体的顶部可以形成有避让凹部16，或者连接件主体的底部可以形成有避让凹部 16，再或者连接件主体的顶部和底部分别形成有避让凹部16，具体根据第一构件10上的嵌装槽103的位置适应性设置。避让凹部16位于连接件主体一端以使连接件主体的端部呈缺口状。当第一构件10与第二构件20连接后，灯带或电线穿设于嵌装槽103内，且灯带或电线的一部分跨过避让凹部16。
在另外一些实施方式中，嵌装槽103还可以位于第一构件10的具有连接通道11的开口的侧面上，例如图18、图20所示，嵌装槽103的一部分穿过避让凹部16，又例如图19所示，嵌装槽103的一部分滑过连接通道11的开口，以使第一构件10与第二构件20连接后，第一构件10与第二构件20相连接的位置形成有缝隙(该缝隙即为嵌装槽103)，以使电线穿设于嵌装槽103内，且电线的一部分跨过避让凹部16，起到隐藏美观的效果。
在一些实施方式中，如图4、图6、图9、图13所示，连接件主体的背离连接通道11的开口的一端形成有环形倒角部17。一方面，环形倒角部17减小了连接件1在插入连接通道11时的接触面积，起到定位导向作用，同时环形倒角部17减小连接件主体与安装通道101之间的滑动摩擦力，提高连接件1插入安装通道101的顺畅性。另一方面，环形倒角部17使连接件主体的背离连接通道11的开口的一端端部呈圆锥形或圆台形状，当连接件1插入安装通道101后，连接件主体的背离连接通道11的开口的一端端部与安装通道101的底部之间保证预留有一定的空间，该空间用于容纳钻头在第一板材上加工安装通道101时产生的切屑，或者该空间用于因钻头磨损而导致安装通道101的端部加工不完全，保证连接件1能够全部容纳至安装通道101内，避免连接件1部分突出于第一构件10外而导致第一构件10与第二构件20相连接的位置处形成有缝隙，提高第一构件10与第二构件20连接后的美观性。
在一些实施方式中，如图1、图5-图14、图21-图22所示，连接件主体的外侧上形成有定位凹部18。该定位凹部18用于当偏心轮3通 过自动装配机30安装至连接件1的安装孔12时，定位凹部18提供一个夹持位，自动装配机30通过夹持定位凹部18以将连接件1定位在自动装配机30上，避免偏心轮3在压装至安装孔12安装到安装孔12时连接件1发生转动或移动，保证了偏心轮3在连接件1上的装配效率。其中，自动装配机30属于本领域中常规的自动化设备，此处省略赘述自动装配机30的结构及工作原理。本发明并不限制定位凹部18在连接件主体的位置，例如图1、图7-图14所示，定位凹部18位于连接件主体的背离连接通道11的开口的一端的外侧上，此时定位凹部18与环形倒角部17位置发生干涉，以使环形倒角部17不是一个完整的环状；又例如图5、图6所示，定位凹部18位于连接件主体的中央部分的外侧上。
基于上述本实施例1的连接件1的结构，如图6所示，连接件1与二合一或三合一连接件的偏心轮3组成连接组件，偏心轮3可转动地安装于连接件1的安装孔12内。其中，本发明并不限制偏心轮3的结构，例如偏心轮3可以为现有技术中二合一或三合一连接件的偏心轮3结构，即如图15所示，偏心轮3具有偏心槽31，偏心槽31的至少一个内侧壁设有夹紧臂32(夹紧臂32的数量通常为两个，两个夹紧臂32分别设于偏心槽31的相对两侧)。由于偏心轮3先安装在连接件1的安装孔12后一起插入第一构件10的安装通道101内，因此偏心轮3可以预装在安装孔12内，也可以在使用时才将偏心轮3安装在安装孔12内，此处不作限定。优选地，为了提高使用便捷性，通常在销售时将偏心轮3通过自动装配机30预装在安装孔12内，一方面提高装配效率，另一方面保证偏心轮3的偏心槽31的槽口位置对准连接通道11，以使便于后续二合一或三合一连接件的连接杆4穿过连接通道11后插入偏心轮3的偏心槽31内，提高后续的使用效率。
进一步地，当上述本实施例1的连接件1与偏心轮3组成的连接组件与二合一或三合一连接件的连接杆4配合使用时，如图16所示，连接杆4的一端凸出形成有连接凸台41，连接杆4的另一端形成有安 装部42，安装部42例如为外螺纹结构，连接杆4通过安装部42锁紧在第二构件20上；偏心轮3能够在释放位置和锁定位置之间的转动方向上转动；当偏心轮3处于释放位置时，连接凸台41穿过连接通道11插设于偏心槽31内；当偏心轮3处于锁定位置时，夹紧臂32限制连接凸台41从偏心槽31内拔出。
其中，本实施例1并不限制二合一或三合一连接件的连接杆4的结构，例如连接杆4可以为现有技术的二合一或三合一连接件的连接杆4，还可以为中国专利公告号为CN114321115A公开的《一种第一连接件、连接组件及连接系统》中的第一连接件。
基于上述本实施例1的连接组件的结构，如图17-图20所示，连接组件与第一构件10配合使用时，连接组件与第一构件10组成连接系统，具体为：第一构件10的一侧形成有横截面为圆形状的安装通道101，第一构件10的顶部或底部开设有与安装通道101相连通的连接孔102；连接件主体插入安装通道101内，且安装孔12与连接孔102的位置相对应并相连通，以使偏心轮3与连接孔102连通。当偏心轮3及连接件1插入安装通道101后出现安装出错或安装孔12的位置出现偏差造成偏心轮3的中心轴线与连接孔102的中心轴线不在同一直线时，采用操作工具2插入至连接通道11的具有操作截面14部分，驱动连接件1沿连接件主体的中心轴线15并朝相应的方向转动一定角度后，以使偏心轮3的中心轴线与连接孔102的中心轴线处于同一直线，从而使螺丝刀或扳手等工具穿过连接孔102后驱动偏心轮3转动，进而控制连接杆4与偏心轮3相互锁定或释放，完成第一构件10与第二构件20之间的连接或分开。
实施例2
基于上述实施例1的连接件1的结构，如图29-图31所示，本实施例2公开了一种安装工具，用于将连接件1安装于第一构件10的安装通道101内，以使连接件1安装于安装通道101后安装孔12的中心轴线与连接孔102的中心轴线位于同一直线或接近同一直线上，避免 或者减小采用操作工具2对连接件1进行校正。具体地，本实施例2的安装工具5包括第一定位部51、第二定位部52及定位柱55；第二定位部52与第一定位部51相对间隔设置，第一定位部51与第二定位部52通过连接部53相连接，第一定位部51、连接部53及第二定位部52依次围合以形成有定位槽54；定位柱55设于定位槽54内，且定位柱55的一端与连接部53连接，第一定位部51的内侧面与第二定位部52的内侧面分别与定位柱55相对间隔设置，定位柱55用于插装连接通道11内。其中，安装工具5将连接件1安装至安装通道101过程中，可以是连接件1通过连接通道11插装在定位柱55上，或者定位柱55插入连接通道11内。
作为连接件1通过上述本实施例2的安装工具5安装至第一构件10的第一种安装方式，当连接件1通过本发明的安装工具5安装至第一构件10的安装通道101时，可以先将连接件1通过连接通道11插装于定位柱55上，并使偏心轮3的轴线垂直于第一定位部51(偏心轮3的轴线可以在定位槽54内或不在定位槽54内)，由于定位柱55的至少一部分横截面与连接件1的至少一部分连接通道11横截面相同或相近，使得连接件1在安装通道101内不会发生转动或难以发生转动，然后将定位槽54的槽口套在第一构件10的具有安装通道101的一侧，并使连接件1及定位柱55对准第一构件10的安装通道101，接着外力(外力例如为敲打或挤压或推动等)作用于连接部53的外侧面，使连接件1及定位柱55在安装通道101内移动，由于第一定位部51的内侧面贴合于或靠近于第一构件10的上表面、第二定位部52的内侧面贴合于或靠近于第一构件10的下表面，确保连接件1在安装通道101内沿安装通道101的轴向滑动的过程中，偏心轮3的轴线垂直于第一定位部51及第一构件10的上表面，从而使连接件1全部嵌装于安装通道101后，偏心轮3的轴线与安装孔12的轴线位于同一直线上或接近同一直线上，避免偏心轮3的凹槽槽口与安装孔12出现位置偏差、或减小偏心轮3的凹槽槽口与安装孔12之间的位置偏差，从而确保螺 丝刀等工具穿过安装孔12后顺利驱动偏心轮3在第一构件10内转动，提高连接件1在第一构件10上安装精度及装配效率。
作为连接件1通过上述本实施例2的安装工具5安装至第一构件10的第二种安装方式，当连接件1通过本发明的安装工具5安装至第一构件10的安装通道101时，可以连接件1的具有偏心轮3的一端插入安装通道101内，且偏心轮3的轴线垂直于第一构件10的上表面，然后将定位槽54的槽口套在第一构件10的具有安装通道101的一侧，并使定位柱55相应地插入连接件1的连接通道11内，同时第一定位部51的内侧面贴合于或靠近于第一构件10的上表面、第二定位部52的内侧面贴合于或靠近于第一构件10的下表面，接着外力(外力例如为敲打或挤压或推动等)作用于连接部53的外侧面，从而使连接件1插入安装通道101内，且使偏心轮3的轴线与安装孔12的轴线位于同一直线或接近同一直线上。
需要说明的是，本实施例2的偏心轮3的轴线例如可以为偏心轮3的凹槽的中心轴线或接近中心轴线、或者为圆柱体或球体的偏心轮3的中心轴线；安装孔12的轴线例如可以为圆形孔的安装孔12的中心轴线或接近中心轴线。
在一些实施方式中，由于连接件1的连接通道11的横截面呈非圆形状，为了使连接件1在定位柱55上不会发生转动或难以发生转动，定位柱55的横截面形状与连接通道11的横截面形状相同或相近，即定位柱55的至少一部分横截面为非圆形状，例如多边形或梅花形或椭圆形或腰圆形等，其中多边形具体包括三角形或四边形或六边形或其它不规则的多边形，从而确保连接件1在定位柱55上不会发生转动，确保偏心轮3的凹槽槽口平行地朝向于第一定位部51的内侧面。
在一些实施方式中，第一定位部51、第二定位部52、连接部53及定位柱55为一体成型的金属件，例如铁质或不锈钢材质或合金材质等，又例如采用线切割工艺制备而成。
基于上述本实施例2的安装工具5，本发明还公开了一种安装系 统，包括上述实施例1的第一构件10、实施例1的偏心轮3、实施例1的连接件1及实施例2的安装工具5，偏心轮3可转动地安装于安装孔12内，第一构件10的侧面形成有安装通道101，第一构件10的上表面形成有与安装通道101连通的安装孔12；连接通道11的至少一部分横截面的形状与定位柱55的至少一部分横截面形状相配合，连接件1及定位柱55均滑动插装至安装通道101内；其中，在连接件1及定位柱55滑动插装至安装通道101的过程中，偏心轮3的轴线垂直于第一定位部51，且第一定位部51的内侧面贴合于或靠近于第一构件10的上表面，第二定位部52的内侧面贴合于或靠近于第一构件10的下表面；当连接部53的内侧面抵接至第一构件10的侧面时，偏心轮3移动至安装孔12的位置，偏心轮3的轴线与安装孔12的轴线位于同一直线上或接近同一直线上。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示意性实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
