Title (EN) THREADED INTERFACE BUFFER PROVIDED WITH ANTI-ROTATION STRUCTURES
(FR) DISPOSITIF-TAMPON À INTERFACE FILETÉE AYANT DES STRUCTURES ANTI-ROTATION
(ZH) 具有防转结构的螺纹接口缓冲器
Abstract: front page image
(EN) A threaded interface buffer provided with anti-rotation structures, said buffer comprising a buffer housing (1), a buffer core (2) and a drawbar (3), the drawbar (3) comprising a connection portion (4) connected to the buffer core (2). The drawbar (3) is threadedly connected to the buffer core (2) via the connection portion (4), a primary anti-rotation structure (5) limiting the rotation of the drawbar (3) and the buffer core (2) is mounted on said components, and a secondary anti-rotation structure (6) limiting the rotation of the drawbar (3) and the buffer housing (1) is mounted between said components, thereby enhancing the versatility and adaptability of the buffer, and ensuring the operational stability of the buffer.
(FR) L'invention concerne un dispositif-tampon à interface filetée ayant des structures anti-rotation, ledit dispositif-tampon comprenant un logement de dispositif-tampon (1), une partie centrale de dispositif-tampon (2) et une barre d'attelage (3), la barre d'attelage (3) comprenant une partie de liaison (4) reliée à la partie centrale de dispositif-tampon (2). La barre d'attelage (3) est reliée par filetage à la partie centrale de dispositif-tampon (2) par l'intermédiaire de la partie de liaison (4), une structure anti-rotation primaire (5) limitant la rotation de la barre d'attelage (3) et la partie centrale de dispositif-tampon (2) étant montée sur lesdits éléments, et une structure anti-rotation secondaire (6) limitant la rotation de la barre d'attelage (3) et le logement de dispositif-tampon (1) étant monté entre lesdits éléments, ce qui permet d'améliorer la polyvalence et l'adaptabilité du dispositif-tampon et d'assurer la stabilité fonctionnelle du dispositif-tampon.
(ZH) 具有防转结构的螺纹接口缓冲器,包括缓冲器壳体(1)、缓冲器芯子(2)和牵引杆(3),所述牵引杆(3)包括一段与缓冲器芯子(2)连接的连接部(4);牵引杆(3)通过连接部(4)与缓冲器芯子(2)螺纹连接,牵引杆(3)与缓冲器芯子(2)上安装有限制二者转动的一级防转结构(5),牵引杆(3)与缓冲器壳体(1)之间安装有限制二者转动的二级防转结构(6),由此能够增强缓冲器的通用性和适配性,保证缓冲器工作的稳定性。
