FIELD: mechanics.SUBSTANCE: tripod includes base (1) with central hole (2) and three brackets (3) at the base with eyes (4) made in them. Between eyes (4) on conical surface of base (1) there are grooves (5) providing free-from-play connection of legs (6) and base (1) and specifying the required angle between them. Legs (6) have telescopic structure with varying length and are equipped with limit stops (8). A leg clamping device is installed on base (1), which includes instrument fastening device (9) that is rigidly attached to stock (10). Stock (10) is made in the form of a cylinder with flange (11) with possibility of back-and-forth movement in vertical plane by means of a screw pair. Flange (11) ensures fixation of all the legs in transport and working positions. In order to avoid the play of the legs in the working position, adjustment screws (17) are provided. Height and inclination of tripod (1) is changed owing to changing the length of telescopic legs of the tripod.EFFECT: simpler design, smaller weight, improved usability, reduced time of conversion from transport position to the working position and vice versa.4 dwg |
