具体实施方式
以下将结合附图所示的各实施方式对本实用新型进行详细描述。但这些实 施方式并不限制本实用新型，本领域的普通技术人员根据这些实施方式所做出的结构、方法、或功能上的变换均包含在本实用新型的保护范围内。
参照图1-2所示，本实用新型提供的一种金属搭扣组件包括主板1，主板1包括内侧面12和外侧面13，主板1上端形成向内弯曲的开放式的圆弧形结构14，该圆弧形结构形成了一个圆弧形的槽，该圆弧形槽是用于容纳圆柱形轴或连杆状类似物，使得主板能绕轴或连杆旋转，圆弧形槽的内壁上设有凸点17，该凸点可以设置一个，也可以设置多个，依具体的槽的长度而定，凸点可以是通过向内冲压圆弧形结构14的表面而形成，也可以通过其他方式增加，凸点起到了对轴或连杆进行限位的作用，防止主板在旋转的过程中脱落出，凸点外表面最好为圆滑结构，从而不会影响主板的转动。
再参照图1-3所示，主板1左右两端都向内侧面弯折一定角度，最好为90度，从而形成了两个折弯的端面15、16，扣板2左右两端也相应的向内侧面弯折相同的角度形成折弯部24、25，主板1除去折弯部后的长度应与扣板2除去折弯部的长度大致相同，因此扣板2才能被压装入主板1的内侧面12上，最好被压装在主板1的大致中间位置，压装后扣板2的外侧面紧压贴在主板的内侧面12上，折弯部24、25的外侧面也分别紧压贴住主板1的折弯的端面15、16的内侧面上，从而扣板2就被通过压装的方式固定到了主板1上。
参照图4-5所示，扣板2’也可以通过铆钉铆接到主板1上，扣板2’的折弯部24’、25’设有铆钉孔241’、251’，同时主板1的折弯端面15、16上也设有铆钉孔(图中未标出)，通过铆钉3将主板1和扣板2’铆接在一起，当然也可也使用螺纹联接，销联接或焊接等其他连接方式。
需要注意的是，所述主板和扣板通常均为金属材料制成，但在保证强度足够的前提下扣板也可以由塑料或者其他材料制成。
再参照图3-4和6所示，扣板2上设有三个勾部21、22、23，三个勾部末端均向内弯折一次或两次，或者其中一个向内弯折两次，其他两个向内弯折一次，当勾部与箱体上设置的凸台配合时，末端向内弯折一次的勾部与凸台相互 支撑，防止上下晃动，勾部末端向内弯折一次一方面能使得定位效果更好，另一方面也避免了在装配金属搭扣的过程中，冲压成型的金属板的毛边破坏箱体上的塑料凸台结构。末端向内折弯两次的勾部，不仅可以防止上下晃动也可以防止左右晃动，主要起到扣合的作用，使金属搭扣被稳固的扣合到箱体上。为了达到更好的扣合和支撑的作用，勾部的折弯的角度和形状也可也是多样的。如图6所示的其中一种方式是中间位置的勾部22”末端向内折弯两次，两边的勾部21”、23”末端向内弯折一次，且折弯度较平缓，两边的勾部21”、23”主要用于支撑作用，中间的勾部22”主要用于扣合的作用，这样的对称布置，扣合稳定，强度好。如图3所示的另一种方式是三个勾部21、22、23均作出较为平缓的双折弯形状，这样的设计使得扣合效果更好更稳定。如图4中所示的另一种方式是中间的勾部22’的背部221’向上以一定的角度延伸后再在末端位置折弯，且折弯角度较大，折弯角度大于90度，勾部22’形成了一个锐角，这样的设置是为了更好的与箱体上的凸台配合达到扣合锁定的效果，勾部21’和23’的折弯角度相对平缓，主要是起支撑限位的作用。
参照图7-8所示，在另一种实施方式中，在主板1的上端圆弧形槽的内壁也可以不设置凸点，而采用钢丝连杆4来对容纳在槽里面的轴或连杆进行限位，钢丝连杆包括连接部和抵触部，钢丝连杆的形状可以设置成如图8所示的形状，左右两端对称设置的折弯部41、42分别连接至主板折弯的左右端面15、16的孔(图中未标出)内，钢丝连杆4对称的上端部43、44用于抵住容纳在槽里面的轴或连杆，从而避免了主板在旋转的过程中脱落出。这样的钢丝连杆的设计结构简单，拆卸方便，成本低，能很好的起到限位的作用。
本实用新型一较佳实施方式中，参照图9所示，一种箱体式组合工具5，包括上盖51，中盖52，和箱体53，金属搭扣组件6用于连接中盖52和箱体53，金属搭扣组件7用于连接上盖51和中盖52。具体的，参照图11所示，中盖52上设有连杆59包括杆部59a、59b，中部位置一体成型有筋板59c，筋板59c的作用是加强连杆的强度，连杆较短的时候，强度好的时候则不需要增加筋板， 当连杆较长的时候为了增加连杆的强度需要增加筋板，箱体53的对应位置设有三个凸台58，这三个凸台的形状相同均是由横向筋板和纵向筋板组成，中间凸台的长度小于两边凸台的长度，凸台长度也可以是相同，具体根据空间位置的需要设置。参照图11-13所示，当金属搭扣组件6装配到箱体式组合工具5上时，金属搭扣组件6的上端部62a与中盖52上的连杆59a配合，62b与连杆59b配合，槽62c与筋板59c配合，中盖52上的连杆被卡入金属搭扣6上端部形成的圆弧形槽内，从而金属搭扣组件6即被安装到了中盖52上可以绕中盖52上的连杆旋转，在凸点621的限制下，连杆不会轻易地从圆弧形槽内脱落出且金属搭扣组件可以绕连杆能够随意转动，但只要施加足够的力又能使连杆越过凸点从槽内分离出，从而可以将金属搭扣从中盖上拆下。
参照图18所示，在另一种实施方式中也可以利用钢丝连杆8抵住连杆59使得连杆59不会从金属搭扣组件6上端的圆弧形槽内脱落出。需要拆卸金属搭扣组件时，只需要先把钢丝连杆8拆卸下，即可以解除锁定，然后将金属搭扣组件拆卸下。
参照图13所示，当金属搭扣组件6往箱体方向旋转实现扣合时，金属搭扣组件6上的勾部61与箱体上的凸台58接触配合，勾部61对凸台58起到支撑和扣合的作用，防止上下左右晃动，将中盖52紧密的锁定到箱体53上。
参照图14所示，上盖51上设有连杆54a、54b，中部位置一体成型有筋板54c，筋板54c的作用是加强连杆的强度，中盖52上设置有三个凸台55、56、57，两边的凸台55和57形状相同均是由上筋板和两个侧筋板组成，中间的凸台57也是由上筋板和两个侧筋板组成，但是上筋板中间设有穿孔，凸台的长度和形状可以根据具体的需要作出适应的调整。参照图14-16所示，当金属搭扣组件7装配到箱体式组合工具5上时，金属搭扣组件7的上端部74a、74b、74c相应地与上盖51上的连杆54a、54b、54c对应配合，从而金属搭扣组件7即被安装到了上盖51上，可以绕上盖上的连杆旋转，同样在凸点的作用下防止脱落，同时又可以被拆卸下，当金属搭扣组件7绕连杆往箱体方向旋转直到金属搭扣 组件上的勾部与中盖上的凸台相抵接的时候则实现扣合，参照图16-17所示，扣合时，两边的凸台55、56与金属搭扣组件7两边的勾部73、72配合，此时的凸台55、56对勾部73、72主要起到支撑作用，防止上下晃动，中间的勾部71与凸台57配合，勾部71的顶端部分被卡入57的穿孔内起到锁紧限位的作用，防止上下左右晃动，中间的勾部71主要实现了扣合的作用，从而将上盖51锁紧到中盖52上。
