Abstract

L'invention concerne une dent de fermeture à glissière ronde comprenant un corps de dent de fermeture à glissière (1). Le corps de dent de fermeture à glissière (1) est un corps colonnaire semi-circulaire. Une extrémité de deux surfaces d'engrènement (11 et 12) du corps de dent de fermeture à glissière (1) est en retrait vers le corps de dent de fermeture à glissière (1) en vue de former une partie d'engrènement (13) et des parties évidées d'engrènement (11b et 12b). Des parties de positionnement (11a et 12a) sont disposées de manière correspondante sur les parties évidées d'engrènement (11b et 12b). Une rainure de positionnement (13a) est disposée sur la partie d'engrènement (13). La conception structurale de la dent de fermeture à glissière ronde est unique : lorsque les dents de fermeture à glissière sont engrenées les unes avec les autres, les dents de fermeture à glissière engrenées les unes avec les autres sont de forme ronde ; par comparaison avec l'état de la technique, les dents de fermeture à glissière rondes sont verrouillées par double engrènement lorsqu'elles sont engrenées les unes avec les autres, la partie d'engrènement (13) de la dent de fermeture à glissière est en prise avec les parties évidées d'engrènement (11b et 12b) d'une autre dent de fermeture à glissière, les parties de positionnement (11a et 12a) de la dent de fermeture à glissière sont verrouillées en prise avec la rainure de positionnement (13a) de l'autre dent de fermeture à glissière, les dents de fermeture à glissière sont verrouillées par engrènement dans deux directions dimensionnelles, les dents de fermeture à glissière coopérant peuvent être engrenées avec une plus grande fermeté. Même lorsqu'elles sont arrachées par une grande force externe dans les directions gauche et droite, les dents de fermeture à glissière en prise les unes avec les autres sont peu susceptibles de se désolidariser.
