The utility model relates to a nut adjusting seat which comprises a main seat surface, a base and left and right overturning seat surfaces, wherein the main seat surface is hinged with the left and right overturning seat surfaces through hinges, a supporting rod is hinged with the left and right overturning seat surfaces, a screw rod is fixed at the bottom of the base, a nut is connected to the screw rod, a retaining sleeve which can rotate relatively to the nut and move up and down along the screw rod along with the nut is arranged on the nut, and the other end of the supporting rod is hinged on the retaining sleeve.

Preferably, the nut is provided with a supporting concave table for supporting the bottom of the retaining sleeve, the side wall of the nut above the retaining sleeve is provided with an annular limiting groove, and the limiting groove is internally provided with an elastic retainer ring. The upper end and the lower end of the limit retaining sleeve can be simply and conveniently limited.

Preferably, a limiting hole is formed in the bottom of the screw rod, and a limiting bolt for preventing the bottom of the nut from falling out of the screw rod is fixed in the limiting hole. Preventing the nut from falling out of the bottom of the screw rod.

As one preferable mode, the hinge comprises a fixed hinge fixed with the main seat surface and a movable hinge fixed with the left and right overturning seat surfaces, the movable hinge is provided with an ear plate in an integral stamping mode, the manufacturing is more convenient, and the upper end of the supporting rod is hinged on the ear plate through a pin shaft.

The utility model has the following beneficial effects:

through adjusting nut's high position on the lead screw to adjust the height that keeps the cover, reach the purpose of controlling upset seat and main seat contained angle, the adjustable contained angle of controlling upset seat is more selected more accurately, more can adapt to market demand, and can shorten the height of stay tube, reserve enough space for the bottom of seat, reduced the potential safety hazard, simple structure in addition, the cost is lower.
