Title (EN) EXPANSION SCREW
(FR) VIS D'EXPANSION
(ZH) 一种膨胀螺丝
Abstract:
(EN) An expansion screw, comprising an expansion plate (1), a movable support screw rod (2) and a fixed ejection piece (3), wherein the movable support screw rod (2) comprises a U-shaped support portion (21) and a screw rod portion (22); a first U-shaped groove (23) is formed on the U-shaped support portion (21); the fixed ejection piece (3) comprises an ejection rod portion (31) and a fixed support portion (32); the fixed support portion (32) forms a second U-shaped groove (33); the second U-shaped groove (33) of the fixed ejection piece (3) passes through the first U-shaped groove (23) of the movable support screw rod (2) to be sheathed on the first U-shaped groove (23), so that the screw rod portion (22) is positioned in the second U-shaped groove (33), and the ejection rod portion (31) is positioned in the first U-shaped groove (23); the lower portion of the screw rod portion (22) is sheathed with a flat gasket (4); and a nut (5) is mounted under the flat gasket (4). When a load is increased, the movable support screw rod is pulled outwards, and the ejection rod portion pushes inwards; in such a way, the expansion plate is expanded gradually, and the expansion screw is fixed firmly.
(FR) L'invention concerne une vis d'expansion, comprenant une plaque d'expansion (1), une tige de vis de support mobile (2) et une pièce d'éjection fixe (3), la tige de vis de support mobile (2) comprenant une partie support en U (21) et une partie tige de vis (22) ; une première rainure en U (23) est formée sur la partie support en U (21) ; la pièce d'éjection fixe (3) comprend une partie tige d'éjection (31) et une partie support fixe (32) ; la partie support fixe (32) forme une seconde rainure en U (33) ; la seconde rainure en U (33) de la pièce d'éjection fixe (3) traverse la première rainure en U (23) de la tige de vis de support mobile (2) devant être gainée sur la première rainure en U (23), de telle sorte que la partie tige de vis (22) est positionnée dans la seconde rainure en U (33), et la partie tige d'éjection (31) est positionnée dans la première rainure en U (23) ; la partie inférieure de la partie tige de vis (22) est gainée d'un joint plat (4) ; et un écrou (5) est monté sous le joint plat (4). Lorsqu'une charge est augmentée, la tige de vis de support mobile est tirée vers l'extérieur, et la partie tige d'éjection pousse vers l'intérieur ; de telle sorte que la plaque d'expansion est élargie progressivement, et que la vis d'expansion est fermement fixée.
(ZH) 一种膨胀螺丝,包括膨胀板(1),活动支架螺丝杆(2)和固定顶件(3),其中活动支架螺丝杆(2)包括U支架部(21)和螺杆部(22),U支架部(21)上形成有第一U形槽(23);固定顶件(3)包括顶杆部(31)和固定支架部(32),固定支架部(32)形成第二U形槽(33);固定顶件(3)的第二U形槽(33)穿过活动支架螺丝杆(2)的第一U形槽(23)套在第一U形槽(23)上使得螺杆部(22)位于第二U形槽(33)内,顶杆部(31)位于第一U形槽(23)内;螺杆部(22)下方套有平面垫片(4),平面垫片(4)的下方安装有螺母(5)。当载荷越重时,越会将活动支架螺丝杆往外拉,相对地,顶杆部则向里顶,膨胀板被撑的越大,从而膨胀螺丝固定的越牢固,不易脱落。
