Description

一种连接组件及连接系统 技术领域
本发明涉及一种连接组件及连接系统，连接组件用于连接第一构件和第二构件，特别用于连接家具构件。
背景技术
目前，随着人们的审美观念不断提高，两个家具板件或两个金属构件之间逐渐采用隐形连接件实现隐形式连接，从而提高家具或设备的美观性，其中，三合一连接件或二合一连接件广泛应用于两个家具板件之间的连接。但是，使用现有三合一连接件的偏心轮的板件开孔直径较大(通常需要大于等于10mm)，用户容易通过较大的孔径观察到偏心轮，从而导致三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CN216519026U公开了《一种加固件、连接组件及连接系统》，先将偏心轮预装在加固件上，然后偏心轮随加固件从板件的一侧插装在第一构件的安装通道，使得偏心轮与第一构件的第一安装孔相连通，最后采用螺丝刀等工具穿过第一安装孔以驱动偏心轮与连接杆相互锁紧，从而完成第一构件与第二构件之间的隐形性连接。由于偏心轮不需要从第一安装孔安装至板件内，使得第一安装孔的孔径只需要供螺丝刀等工具穿过即可，极大地减小了第一安装孔的孔径，从而提高了偏心轮在板件上的隐形性。
但是，上述现有技术的加固件通过紧固倒牙紧固在板件的内部，导致加固件安装结束后难以从板件上拆除，当加固件出现安装位置偏差或需要将加固件与板件相互拆分时，需要破坏板件后才能将加固件拆除，操作难度大且效率低，同时不利于板件的美观性或循坏使用。

实施例1
如图1-图29所示，本发明实施例1提供了一种连接组件，包括加固件1、偏心轮2及插件3。加固件1具有相对置的连接端11和安装端12，连接端11的端部形成有连接通道13，连接端11的侧壁上形成有至少一个形变间隙14，连接端11的一部分通过形变间隙14限定形成有至少一个弹性部15,弹性部15的外侧壁上形成有紧固凸起151；加固件1的外侧壁上形成有与连接通道13相连通的安装空间16；偏心轮2可转动地安装于安装空间16内；插件3形成有贯穿于插件3两端的插接通道31，插件3的一端从连接端11插入连接通道13内；插接通道31的至少一部分用于与外部工具配合插接以驱动插件3在连接通道13内移动，或，插接通道31的至少一部分用于与外部工具配合插接以驱动插件3在连接通道13内转动；其中，插接通道31的内侧壁上具有至少一个操作平面或操作凸点或操作凹槽；或，插接通道31的至少一部分的横截面形状与套筒内圈的横截面形状相同；其中，插件3能够在松开位置与锁紧位置之间切换；当插件3从松开位置往锁紧位置切换时，插件3驱动弹性部15的至少一部分发生弹性形变并向外张开。
使用时，偏心轮2先预装在加固件1的安装空间16内且在安装空间16内可转动，偏心轮2与加固件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的顶部或底部以驱动偏心轮2在安装空间16内转动，从而使偏心轮2与连接杆4相互锁定或释放。由于偏心轮2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上的孔位只需要供螺丝刀等工具穿过即可，极大地提高了偏心轮2在第一构件10上的隐形性。
其中，本发明实施例1并不限定安装空间16的具体形状及尺寸，具体根据偏心轮2的形状及尺寸适应性设计，只要满足偏心轮2能够 在安装空间16内转动即可。
为了使偏心轮2通过本发明实施例1的加固件1安装至第一构件10的内部，如图14-图16所示，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的横截面形状与加固件1的横截面形状相适配，安装通道101的横截面面积等于或略大于加固件1的横截面面积，以使加固件1插入安装通道101的过程中，加固件1的外侧壁与安装通道101的内侧壁相互贴合或接近贴合或存在很小的间隙，以使加固件1能够很轻松地插装至安装通道101内或从安装通道101中拔出。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等工具穿过即可)，当加固件1插入安装通道101后并使安装空间16的位置与连接孔102的位置相对应并相连通，使得螺丝刀等工具穿过连接孔102后直接驱动偏心轮2在安装空间16内转动。
进一步地，安装通道101是通过钻孔工艺加工而成，为了适配安装通道101的横截面形状，加固件1为圆柱体或圆台状，即沿连接端11往安装端12的观察方向上，加固件1呈圆形状，以使加固件1更轻松插装至安装通道101内。
由于加固件1与安装通道101之间的滑动摩擦力较小，导致加固件1容易从安装通道101内拔出。因此，在加固件1插入第一构件10的安装通道101后，插件3的一端插入连接通道13内，当插件3从松开位置往锁紧位置切换时，插件3驱动加固件1的弹性部15的至少一部分发生弹性形变并向外张开，使得弹性部15上的紧固凸起151抵紧至安装通道101的内侧壁，增大加固件1在安装通道101内的滑动摩擦力，以使加固件1难以在安装通道101内滑动，从而将加固件1紧固在安装通道101内。当需要将加固件1从第一构件10上拆除时，将插件3调整至松开位置，使弹性部15恢复至原状，解除弹性部15上的紧固凸起151与安装通道101之间的抵紧效果，从而使加固件1能 够在安装通道101内自由滑动，进而将加固件1从安装通道101内轻松拔出，操作便捷且效率高，同时避免对第一构件10造成破坏，有效保证了板件的完整性及美观性，有利于板件的循环使用。
需要说明的是，本实施例1并不限定插件3的外轮廓形状，例如插件3的横截面的外轮廓形状为圆形或椭圆形或腰圆形等，连接通道13的横截面的形状与插件3的外轮廓形状相适配即可。同时连接通道13的长度尺寸大于插件3的长度尺寸，以使插件3能够全部插入连接通道13的内部，以实现第一构件10与第二构件20之间的隐形性连接。
本实施例1的松开位置是指弹性部15未发生弹性形变时插件3的位置，具体可以为插件3未插入连接通道13或插件3的一部分插入连接通道13。锁紧位置是指弹性部15发生弹性形变时插件3的位置，具体可以为插件3完全插入连接通道13内或插件3的一部分插入连接通道13。当插件3从松开位置往锁紧位置切换的过程中，弹性部15逐渐发生弹性形变，弹性部15的紧固凸台对连接通道13的内侧壁的抵紧效果越来越大，当插件3的全部插入连接通道13时，弹性部15的紧固凸台对连接通道13的内侧壁的抵紧效果最大，此时加固件1在连接通道13内的紧固效果最好。
为了控制插件3在松开位置与锁紧位置之间切换，本实施例1通过外部工具(如柱状体等)插入插接通道31内，通过驱动插件3在连接通道13内转动，从而调整插件3在加固件1内的位置。其中，为了使外部工具(如柱状体等)插入插接通道31后驱动插件3转动，插接通道31的至少一部分的横截面形状为非圆形，例如插接通道31靠近其开口的一部分的横截面为非圆形状，插接通道31另一部分的横截面为圆形状；又例如插接通道31整体的横截面形状相同且为非圆形状。具体地，本发明实施例1的外部工具为与插接通道31的横截面形状相适配的柱状体，当外部工具插入插接通道31后，外部工具的至少一部分与插接通道31的内侧壁相互抵接，以使转动的柱状体能够驱动插件3在连接通道13内转动。
在另一种实施方式中，为了控制插件3在松开位置与锁紧位置之间切换，如本实施例1通过外部工具(如柱状体等)通过驱动插件3在连接通道13内平移，从而使插件3从松开位置移动到锁紧位置；通过外部工具(如钩状件等)通过驱动插件3在连接通道13内平移，从而使插件3从锁紧位置移动到松开位置；以调整插件3在加固件1内的位置。
如图1、图10、图26、图29所示，插接通道31的至少一部分的横截面形状与套筒内圈的横截面形状相同，此时插接通道31的至少一部分为套筒扳手的套筒结构，其中套筒扳手为本领域中常用工具，例如为国标GB T 3390.1-2004的手动套筒扳手，或者其他国标的手动套筒扳手或电动扳手，呈套筒结构的插接通道31的横截面为非圆形，包括但不限于三角形或方形或六边形或八边形或椭圆形或腰圆形或花瓣形等，外部工具的横截面形状与插接通道31的横截面形状相适配，以使外部工具插入插接通道31后驱动插件3在连接通道13转动，从而调整插件3在连接通道13内的位置。
进一步地，本发明并不限定形变间隙14的数量、位置、形状或尺寸，形变间隙14的数量可以为一个或多个，例如图7、图17、图20、图25、图28，当形变间隙14为两个时，两个形变间隙14分别设于连接端11的左右两侧，连接端11的左右两侧分别通过形变间隙14限定形成弹性部15。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及以上)，在第一构件10的侧壁开设有安装通道101后，第一构件10在安装通道101位置的上下方向厚度较薄，当加固件1滑动插入安装通道101的过程中，为了避免弹性部15对第一构件10的顶部或底部造成损坏，弹性部15应当设于第一构件10的长度方向或宽度方向上，两个弹性部15分别沿第一构件10的长度方向或宽度方向间隔设置，从而保证第一构件10不被弹性部15造成损坏。其中，本发明的左右方向是加固件1安装在第一构件10后沿第一构件10的长度方向或宽度方向。
形变间隙14的形状可以为V字形或U字形或7字形等，形变间隙14可以为连续设置而成或间断设置而成，只需要满足连接端11的侧壁的一部分通过形变间隙14能够发生弹性形变即可，即连接端11的一部分通过形变间隙14形成弹性部15。
下面针对本发明的插件3驱动弹性部15发生弹性形变并向外张开的结构做详细说明。
如图1-图9、图17-图20所示，作为插件3驱动弹性部15发生弹性形变并向外张开的第一种具体实施方式，弹性部15的内侧壁与连接通道13的内侧壁共同限定形成有第一内螺纹部17，插件3的外周侧壁上形成有与第一内螺纹部17配合螺纹连接的第一外螺纹部32。其中，采用外部工具(如柱状体等)插入插接通道31内驱动插件3在连接通道13内转动，通过第一外螺纹部32与第一内螺纹部17之间旋转运动转化为插件3在连接通道13内滑动，从而使插件3插装至连接通道13内。同时，当插件3插入连接通道13的弹性部15的部分时，插件3的外周壁抵顶弹性部15以使弹性部15发生弹性形变并向外张开，从而使弹性部15的紧固凸台抵紧至安装通道101的内侧壁，进而将加固件1紧固在安装通道101内。加固件1的具体加工工艺可以如下：连接通道13在连接端11部分加工有连续的内螺纹结构，然后在连接端11的侧壁上加工有形变间隙14以限定形成有弹性部15，使得弹性部15上内螺纹结构与连接通道13的内螺纹结构共同形成第一内螺纹部17。第一内螺纹部17的齿体可以为直齿或斜齿，第一外螺纹部32的齿体相适应为直齿或斜齿。
进一步地，上述第一种实施方式并不限定连接通道13在连接端11部分的结构，例如，沿连接端11往安装端12的方向上，连接通道13在弹性部15的部分的截面的形状及面积均相同(即呈圆柱体状)，又例如，沿连接端11往安装端12的方向上，连接通道13在弹性部15的部分的截面的面积逐渐减小(即呈圆台状)；再例如，沿连接端11往安装端12的方向上，连接通道13在弹性部15的部分的截面的面积 先逐渐变大后变小。
如图4、图7、图12、图13所示，当沿连接端11往安装端12的方向上，连接通道13在弹性部15的部分的截面的形状及面积均相同，紧固凸起151的外轮廓所在的外周圆的横截面面积大于安装端12的外轮廓所在的外周圆的横截面面积。此时插件3为外周壁带第一外螺纹部32的圆柱体结构。如此当加固件1插入安装通道101后，紧固凸起151与安装通道101的内侧壁相互贴合，加固件1在安装通道101内就产生有一定的摩擦以保证插件3顺利旋入连接通道13内，同时插件3与弹性部15接触后就驱动弹性部15发生弹性形变，使紧固凸台抵紧至安装通道101的内侧壁，保证加固件1在安装通道101内的紧固效果。
如图19、图20所示，当沿连接端11往安装端12的方向上，弹性部15的内侧壁逐渐靠近连接通道的中心轴线131。同样地，插件3为外周壁带第一外螺纹部32的圆柱体结构。其中，紧固凸起151的外轮廓所在的外周圆的横截面面积等于安装端12的外轮廓所在的外周圆的横截面面积，或者紧固凸起151的外轮廓所在的外周圆的横截面面积大于安装端12的外轮廓所在的外周圆的横截面面积。优选地，紧固凸起151的外轮廓所在的外周圆的横截面面积可以等于安装端12的外轮廓所在的外周圆的横截面面积，由于插件3为呈圆柱体结构，且插件3的横截面面积大于弹性部15内侧壁所在的横截面面积，使得当插件3移动至连接通道13的弹性部15的部分时，插件3抵顶弹性部15发生较大的弹性形变，从而使紧固凸起151的外轮廓所在的外周圆的横截面面积大于安装端12的外轮廓所在的外周圆的横截面面积，进而使紧固凸台抵紧至安装通道101的内侧壁，保证加固件1在安装通道101内的紧固效果。
进一步地，上述第一种实施方式中当插件3完全插入连接通道13后，再次驱动插件3转动即可带动加固件1在安装通道101内转动，从而对加固件1在安装通道101内位置进行微调，提高加固件1在第 一构件10内的安装精度。
当需要将加固件1从第一构件10上拆除时，先驱动插件3反向转动以使插件3从连接通道13内全部移出，使弹性部15恢复至原状，解除弹性部15上的紧固凸起151与安装通道101之间的抵紧效果，然后加固件1能够从安装通道101内轻松拔出。
如图21-图26所示，作为插件3驱动弹性部15发生弹性形变并向外张开的第二种具体实施方式，连接通道13的内周侧壁呈光滑状，弹性部15上靠近安装空间16的一端的内侧壁上形成有连接环部18，连接环部18的外周侧与连接通道13的内周侧相对间隔设置，连接环部18的内周侧形成有第二内螺纹部181，插件3的外周侧壁上形成有与第二内螺纹部181配合螺纹连接的第二外螺纹部33。采用外部工具(如柱状体等)插入插接通道31内驱动插件3通过间隙配合滑动插入连接通道13内，当插件3滑动至连接环部18时，驱动插件3相对连接环部18转动，通过第二外螺纹部33与第二内螺纹部181之间旋转运动转化为插件3在连接环部18内滑动，以使插件3进一步插入连接通道13内。当插件3的端部抵接至连接通道13内的台阶后，再次驱动插件3转动即可带动连接环部18及弹性部15发生弹性形变并向外张开，从而使弹性部15的紧固凸台抵紧至安装通道101的内侧壁，进而将加固件1紧固在安装通道101内。其中，紧固凸起151的外轮廓所在的外周圆的横截面面积大于或等于安装端12的外轮廓所在的外周圆的横截面面积。
当需要将加固件1从第一构件10上拆除时，先驱动插件3反向转动以使插件3从连接环部18移出，使弹性部15恢复至原状，解除弹性部15上的紧固凸起151与安装通道101之间的抵紧效果，然后驱动插件3从连接通道13内全部滑出，最后加固件1能够从安装通道101内轻松拔出。
如图27-图29所示，作为插件3驱动弹性部15发生弹性形变并向外张开的第三种具体实施方式，连接通道13的内周侧壁呈光滑状；沿 连接端11往安装端12的方向上，弹性部15上靠近安装空间16的一端的内侧壁逐渐靠近连接通道的中心轴线131；插件3的外周侧壁呈光滑状，插件3的一端的外侧壁上设有解锁凹槽34。在插件3插装至连接通道13时，先将解锁凹槽34的位置对准弹性部15的位置，然后采用外部工具(如柱状体等)插入插接通道31内驱动插件3通过间隙配合滑动插入连接通道13内，当解锁凹槽34的位置滑动至弹性部15时，驱动插件3在连接通道13内转动一定角度(例如90°或80°等)，以使插件3的弧形外侧壁抵顶至弹性部15，驱动弹性部15弹性形变并向外张开，从而使弹性部15的紧固凸台抵紧至安装通道101的内侧壁，进而将加固件1紧固在安装通道101内。其中，紧固凸起151的外轮廓所在的外周圆的横截面面积大于或等于安装端12的外轮廓所在的外周圆的横截面面积。
当需要将加固件1从第一构件10上拆除时，先驱动插件3反向转动一定角度(例如-90°或-80°等)，以使解锁凹槽34的位置与弹性部15的位置相对应(弹性部15插入解锁凹槽34内)使弹性部15恢复至原状，解除弹性部15上的紧固凸起151与安装通道101之间的抵紧效果，然后驱动插件3从连接通道13内全部滑出，最后加固件1能够从安装通道101内轻松拔出。
在一些实施方式中，当上述本发明实施例1的连接组件与连接杆4配合使用时，加固件1及偏心轮2安装至第一构件10上，连接杆4的一端凸出形成有连接凸台41，连接杆4的另一端设有安装部42，连接杆4通过安装部42(安装部42例如为外螺纹结构)锁紧在第二构件20上，连接凸台41与安装部42之间固定设有操作部，操作部与连接凸台41相对间隔设置以形成有连接凹槽，操作部用于被外部工具驱动以带动连接杆4的至少一部分转动，操作部为塑料材质；其中，操作部的外侧壁上具有至少一个操作平面或操作孔或操作凸点或操作凹槽，或，操作部的横截面适配于套筒的横截面；偏心轮2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2处于释放位置时，连 接凸台41穿过插接通道31插设于偏心槽23内；当偏心轮2处于锁定位置时，夹紧臂24限制连接凸台41从偏心槽23内拔出。其中，本实施方式的连接杆4的具体结构及连接杆4与第二构件20的安装方式，请参考中国专利公告号为CN114321115A公开的《一种第一连接件、连接组件及连接系统》中的第一连接件及其安装方式，此处省略赘述。
如图11、图14-图16所示，当上述本发明实施例1的连接组件安装在第一构件10后组成连接系统，具体为：第一构件10的一侧开设有安装通道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；加固件1插入安装通道101内，且安装空间16与连接孔102的位置相对应并相连通，以使偏心轮2与连接孔102连通；当插件3从松开位置往锁紧位置切换时，插件3驱动弹性部15的至少一部分发生弹性形变并向外张开，以使紧固凸起151抵紧至安装通道101的内侧壁。在加固件1插装至安装通道101后，将插件3的一端插入连接通道13内，当插件3从松开位置往锁紧位置切换时，插件3驱动加固件1的弹性部15的至少一部分发生弹性形变并向外张开，使得弹性部15上的紧固凸起151抵紧至安装通道101的内侧壁，增大加固件1在安装通道101内的滑动摩擦力，以使加固件1难以在安装通道101内滑动，从而将加固件1紧固在安装通道101内。当需要将加固件1从第一构件10上拆除时，将插件3调整至松开位置，使弹性部15恢复至原状，解除弹性部15上的紧固凸起151与安装通道101之间的抵紧效果，从而使加固件1能够在安装通道101内自由滑动，进而将加固件1从安装通道101内轻松拔出，操作便捷且效率高，同时避免对第一构件10造成破坏，有效保证了板件的完整性及美观性，有利于板件的循环使用。
实施例2
如图30-图33所示，本发明实施例2公开了一种连接组件，其与上述实施例1的连接组件结构相似，其不同之处在于：本实施例2的连接 组件不包括插件3，且本实施例2的连接组件的偏心轮2’的外周侧壁为偏心弧面，且连接组件的加固件1’的安装空间为偏心孔14’结构，通过偏心轮2’在偏心孔14’内转动以驱动加固件1’的一部分发生弹性形变并向外张开，从而使加固件1’紧固在第一构件10的内部。
具体地，本发明实施例2的连接组件包括加固件1’和偏心轮2’，加固件1’具有相对置的连接端11’和安装端12’，连接端11’的端部形成有连接通道13’，安装端12’形成有与连接通道13’相连通的偏心孔14’，安装端12’的外侧壁上形成有与偏心孔14’相连通的形变间隙15’，安装端12’的外侧壁上形成有紧固凸起16’；偏心轮2’的外周侧壁为偏心弧面，且偏心轮2’的外周侧壁与偏心孔14’的内周侧壁相适配，偏心轮2’可转动地安装于偏心孔14’内；其中，偏心轮2’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2’从释放位置往锁定位置转动时，偏心轮2’驱动安装端12’的侧壁的一部分发生弹性形变并向外张开。
需要说明的是，如图30-图33所示，本实施例2的偏心孔14’的结构是指偏心轮2’的一部分内侧壁的半径尺寸是绕一个中心轴线逐渐增大或逐渐减小，偏心轮2’的外周侧壁的形状与偏心孔14’的形状相同，以使偏心轮2’通过间隙配合插入偏心孔14’内，然后驱动偏心轮2’转动一定角度后，偏心轮2’半径较大的部分移动至偏心孔14’半径较小的部分，偏心轮2’的外侧壁抵接至偏心孔14’的内侧壁，以使偏心轮2’驱动安装端12’的侧壁的一部分发生弹性形变并向外张开。
其中，如图32-图33所示，本发明的释放位置是指连接杆4’的连接凸台41’能够穿过连接通道13’后插入偏心轮2’的偏心槽23’时偏心轮2’的位置，本发明的锁定位置是指限制连接凸台41’从偏心轮2’的偏心槽23’内拔出时偏心轮2’的位置。
使用时，预装有偏心轮2’的加固件1’通过间隙配合方式滑动插入第一构件10的安装通道101内，并使偏心孔14’的位置与第一构件10的连接孔102的位置相对应并相连通。加固件1’由于加固件1’与安装 通道101之间的滑动摩擦力较小，导致加固件1’容易从安装通道101内拔出。因此，当连接杆4’的连接凸台41’穿过连接通道13’插入偏心轮2’的偏心槽23’后，驱动偏心轮2’从释放位置往锁定位置转动，通过偏心轮2’的外周侧抵顶至偏心孔14’的内周侧，以使安装端12’的侧壁的一部分发生弹性形变并向外张开，使得安装端12’上的紧固凸起16’抵紧至安装通道101的内侧壁，增大加固件1’在安装通道101内的滑动摩擦力，以使加固件1’难以在安装通道101内滑动，从而将加固件1’紧固在安装通道101内。当需要将加固件1’从第一构件10上拆除时，驱动偏心轮2’转动至松开位置，使安装端12’恢复至原状，解除安装端12’上的紧固凸起16’与安装通道101之间的抵紧效果，从而使加固件1’能够在安装通道101内自由滑动，进而将加固件1’从安装通道101内轻松拔出，操作便捷且效率高，同时避免对第一构件10造成破坏，有效保证了板件的完整性及美观性，有利于板件的循环使用。
在一些实施方式中，沿连接端11’往安装端12’的观察方向上，加固件1’呈圆形状。加固件1’呈圆柱体状或圆锥体状，以适配于通过钻孔工艺加工形成的安装通道101，减小加固件1’与安装通道101内侧壁之间的缝隙，提高加固件1’在安装通道101内的安装稳定性。
在一些实施方式中，如图31所示，为了使调整加固件1’在安装通道101的位置，连接通道13’的至少一部分用于与外部工具配合插接以驱动加固件1’转动；连接通道13’的内侧壁上具有至少一个操作平面或操作凸点或操作凹槽；或，连接通道13’的至少一部分的横截面形状与套筒内圈的横截面形状相同。具体地，通过外部工具(如柱状体等)插入连接通道13’后，通过驱动加固件1’在安装通道101内转动一定角度，从而调整安装空间的位置以保证偏心轮2’的位置与第一构架的连接孔102位置相对应并相连通，保证螺丝刀等工具穿过连接孔102后作用于偏心轮2’上，操作简单且效率高，避免了安装空间与连接孔102的位置不相对应的麻烦，从而保证第一构件10的完整性及美观性。其中，为了使外部工具(如柱状体等)插入连接通道13’后驱动 加固件1’转动，连接通道13’的至少一部分的横截面形状为非圆形，例如连接通道13’靠近其开口的一部分的横截面为非圆形状，连接通道13’另一部分的横截面为圆形状；又例如连接通道13’整体的横截面形状相同且为非圆形状。具体地，本发明实施例2的外部工具为与连接通道13’的横截面形状相适配的柱状体，当外部工具插入连接通道13’后，外部工具的至少一部分与连接通道13’的内侧壁相互抵接，以使转动的柱状体能够驱动加固件1’在安装通道101内转动。具体为连接通道13’的至少一部分的横截面形状与套筒内圈的横截面形状相同，此时连接通道13’的至少一部分为套筒扳手的套筒结构，其中套筒扳手为本领域中常用工具，例如为国标GB T 3390.1-2004的手动套筒扳手，或者其他国标的手动套筒扳手或电动扳手，呈套筒结构的连接通道13’11的横截面为非圆形，包括但不限于三角形或方形或六边形或八边形或椭圆形或腰圆形或花瓣形等，外部工具的横截面形状与连接通道13’11的横截面形状相适配，以使外部工具插入连接通道13’11后驱动加固件1’在安装通道101内转动。
如图34所示，当上述本发明实施例2的连接组件安装在第一构件10后组成连接系统，具体为：第一构件10的一侧开设有安装通道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；加固件1’插入安装通道101内，且偏心孔14’与连接孔102的位置相对应并相连通，以使偏心轮2’与连接孔102连通；当偏心轮2’从释放位置往锁定位置转动时，偏心轮2’驱动安装端12’的侧壁的一部分发生弹性形变并向外张开，以使紧固凸起16’抵紧至安装通道101的内侧壁。当预装有偏心轮2’的加固件1’通过间隙配合方式滑动插入第一构件10的安装通道101后，驱动偏心轮2’从释放位置往锁定位置转动，通过偏心轮2’的外周侧抵顶至偏心孔14’的内周侧，以使安装端12’的侧壁的一部分发生弹性形变并向外张开，使得安装端12’上的紧固凸起16’抵紧至安装通道101的内侧壁，增大加固件1’在安装通道101内的滑动摩擦力，以使加固件1’难以在安装通道101内滑动，从而将加 固件1’紧固在安装通道101内。当需要将加固件1’从第一构件10上拆除时，驱动偏心轮2’转动至松开位置，使安装端12’恢复至原状，解除安装端12’上的紧固凸起16’与安装通道101之间的抵紧效果，从而使加固件1’能够在安装通道101内自由滑动，进而将加固件1’从安装通道101内轻松拔出，操作便捷且效率高，同时避免对第一构件10造成破坏，有效保证了板件的完整性及美观性，有利于板件的循环使用。
此外，本实施例2的加固件1’的其他结构与上述实施例1的加固件1的其他结构相同，此处省略赘述。
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。
