Abstract

La présente invention concerne une manchette de pénétration pour un revêtement mural, comprenant : un premier manchon (100) ayant une forme cylindrique et comprenant une première partie de tuyau circulaire (110), dont une extrémité est fermée de telle sorte qu'une première surface d'extrémité (120) est formée, une première broche de fixation (121) étant formée au centre externe de la première surface d'extrémité (120) de telle sorte que celle-ci est ajustée à un trou de fixation (11) d'un moule (10) ; un second manchon (200) ayant une forme cylindrique et comprenant une seconde partie de tuyau circulaire (210), dont une extrémité est fermée de telle sorte qu'une seconde surface d'extrémité (220) est formée, l'autre extrémité du second manchon (200) étant insérée dans la surface périphérique interne de la première partie de tuyau circulaire (110) de façon à coulisser/fonctionner vers la gauche/vers la droite, une seconde broche de fixation (221) étant formée au centre externe de ladite extrémité de façon à être ajustée sur un trou de fixation (21) d'un moule (20) ; et un élément élastique (251) disposé à l'intérieur du premier manchon (100) et du second manchon (200) de telle sorte que le premier manchon (100) et le second manchon (200) appliquent une force élastique aux moules. Une force élastique est appliquée sur les deux côtés extérieurs du premier manchon (100) et du second manchon (200) de telle sorte que, lorsque les deux extrémités de ceux-ci sont ajustées/fixées entre les trous de fixation (11, 21) formés dans les moules (10, 20), la longueur de ceux-ci est ajustée en fonction de l'intervalle entre les moules (10, 20). Un rebord de mise en prise (160) est formé sur la surface périphérique interne de la partie d'extrémité ouverte de la première partie de tuyau circulaire (110) du premier manchon (100). Une première partie de mise en prise (260) est formée sur la surface périphérique externe à proximité de la seconde surface d'extrémité (220) de la seconde partie de tuyau circulaire (210) du second manchon (200) de telle sorte que celle-ci correspond au rebord de mise en prise (160) et peut être fixée à celui-ci. La manchette de pénétration pour un revêtement mural selon la présente invention est avantageuse en ce que la longueur des largeurs des deux extrémités de la manchette de pénétration peut être ajustée rapidement par un corps élastique ; lorsqu'un élément de mise en prise est couplé à un moule, l'élément élastique et la broche de fixation effilée empêchent le détachement ; et, pendant l'assemblage, le volume est réduit par fixation entre le rebord de mise en prise et la première partie de mise en prise, ce qui facilite le stockage et le transport et réduit les coûts.
