Abstract

La présente invention concerne un niveau à bulle. Le tube 4 contenant le liquide et la bulle d'air peut être réglé par un dispositif d'ajustage 28 dans un orifice de réception 24 du boîtier de l'appareil par rapport à la surface de mesure 30. Pour cela on utilise au moins une vis 44, 46, 48 dont l'extrémité conique 42 vient s'appliquer sur un bord conique prévu sur le corps d'enveloppe 20 par exemple. Un organe formant ressort 51 délimite la force d'ajustage de la vis. Grâce à l'invention le réglage du niveau reste constant.The present invention relates to a spirit level. The tube 4 containing the liquid and the air bubble can be adjusted by an adjustment device 28 in a receiving orifice 24 of the housing of the apparatus relative to the measuring surface 30. For this, at least one is used. screw 44, 46, 48 whose conical end 42 comes to rest on a conical edge provided on the casing body 20 for example. A spring member 51 delimits the adjustment force of the screw. Thanks to the invention, the level adjustment remains constant.
