A high-fault-tolerance door nail connecting structure comprises a fixed base, a door nail and a buckle connecting piece. The fixing base comprises a clamping sliding groove, a reinforcing rib, a buckling groove formed in one side of the clamping sliding groove, a limiting groove and a torsion rib. The door nail comprises an anchoring part, a door nail connecting part and an abutting seat. The buckle connecting piece comprises a clamping part and a nail clamping part. The anchoring part comprises a body, an elastic piece, a spacing groove and a buckle groove. And the staple bolt part comprises a staple bolt main body, a door nail insertion hole and an elastic lock catch. Compared with the prior art, the connecting structure has the advantages that the clamping sliding grooves are formed, so that the connecting structure has higher self-adaptive capacity. By arranging the anchoring part, the connecting structure can be suitable for insertion of different sheet metal parts, meanwhile, by controlling the deformation hardness and the buckle included angle, connection at the elastic lock catch position is easier to disengage than connection at the elastic piece position, and therefore the possibility that the anchoring part disengages is reduced, and the connecting effect is improved. And the automobile sheet metal parts are prevented from being damaged due to repeated plugging and unplugging.

    一种高容错门钉连接结构,其包括固定基座,门钉,卡扣连接件。所述固定基座包括卡接滑槽,加强筋,一个设置在所述卡接滑槽一侧的卡扣槽,限位槽,扭筋。所述门钉包括锚定部,门钉连接部,抵顶座。所述卡扣连接件包括卡接部,卡钉部。所述锚定部包括本体,弹片,间隔槽,卡扣凹槽。所述卡钉部包括卡钉主体,门钉插孔,弹性锁扣。与现有技术相比,本发明通过设置所述卡接滑槽,使得连接结构具有更强的自适应能力。通过设置所述锚定部,使得本连接结构可以适用于不同的钣金件进行插入,同时通过控制形变硬度和卡扣夹角,使得所述弹性锁扣处比弹片处的连接更容易脱离,从而减小所述锚定部脱离的可能性,防止因为多次插拔导致的汽车钣金件受损。
