Abstract

La présente invention concerne une lancette de sécurité, dans laquelle un premier ressort (21) et un second ressort (22) sont placés respectivement à deux extrémités à l'intérieur d'un boîtier (1), une tige protectrice est adjacente à une sortie (121) ménagée sur le boîtier (1) et un interrupteur à poussoir (13) est préréglé sur le boîtier (1). Un premier bloc coulissant (3) et un second bloc coulissant (4) sont disposés entre le premier ressort (21) et le second ressort (22) et une aiguille (43) est positionnée sur l'extrémité du second bloc coulissant (4) à l'opposé de la sortie (121). Deux paires de glissières (31,41) s'étendent axialement à partir des faces d'extrémité opposées du premier bloc coulissant (3) et du second bloc coulissant (4), et les deux paires de glissières (31,41) sont logées dans une paire de fentes coulissantes (14) correspondantes à l'intérieur du boîtier (1). Les interfaces des deux paires de coulisses (31,34) ont la configuration de plans inclinés opposés. Les plans inclinés (311,411) sont amenés en contact étroit l'un avec l'autre par la force appliquée par le premier ressort (21) et le second ressort (22). Le premier bloc coulissant (3) comprend en outre une tige d'emboîtement (32) qui s'accroche sur l'interrupteur à poussoir (13), de sorte que le premier ressort (21) est pré-chargé pour être comprimé, ce qui maintient le premier bloc coulissant (3) et le second bloc coulissant (4) dans un état de stockage d'énergie.
