The invention provides a deformable clamping structure which comprises a buckling piece and a clamping piece, the buckling piece comprises a supporting part, an elastic limiting part and a clamping hook part, the elastic limiting part and the clamping hook part are arranged on the supporting part, a via hole is formed in the connecting position of the elastic limiting part and the supporting part, the clamping hook part is located at the via hole, and a first guide face is arranged on the side, opposite to the via hole, of the clamping hook part; the clamping piece comprises a base part and a clamping tongue arranged on the base part, the clamping tongue is provided with a clamping groove used for being matched with the clamping hook part, and the end, away from the base part, of the clamping tongue is provided with a second guide face used for being matched with the first guide face; when the clamping tongue is stressed to be inserted into the through hole, the first guide face and the second guide face are attached and apply pressure, the clamping tongue and the elastic limiting part are stressed to elastically deform so that the clamping tongue can penetrate through the through hole, the clamping hook part can be inserted into the clamping groove, and the elastic limiting part abuts against the side wall of the base part. According to the deformable clamping structure, the problems that when a mold stripping negative angle exists on the modeling surface of the clamping area, the clamping structure cannot be arranged, or clamping is not firm, and the appearance quality is poor can be solved.
本发明提供了一种可变形卡接结构,包括卡扣件和卡合件,卡扣件包括支撑部和设置在支撑部上的弹性限位部、卡钩部,弹性限位部与支撑部的连接处形成过孔,卡钩部位于过孔处,卡钩部与过孔相对的一侧设有第一导向面;卡合件包括基部和设置在基部上的卡舌,卡舌上设有用于与卡钩部相配合的卡槽,卡舌远离基部的一端具有用于与第一导向面相配合的第二导向面;当卡舌受力插入过孔时,第一导向面与第二导向面贴合并施加压力,卡舌及弹性限位部受力发生弹性形变以使卡舌穿过过孔,卡钩部插入卡槽,弹性限位部与基部侧壁相抵接。本发明的可变形卡接结构能够解决当卡接区域的造型面存在出模负角时无法布置卡接结构、或卡接不牢靠、及外观质量差的问题。
