Concrete curing device

The utility model relates to the technical field of concrete curing, and provides a concrete curing device which comprises a curing water tank and a bottom plate, a curing mechanism is arranged in an inner cavity of the curing water tank, and a height adjusting mechanism is arranged in an inner cavity of a direction adjusting mechanism. An operator pulls a pull rod outwards to drive a pull plate and an inserting rod to move outwards to extrude a connecting spring, when the inserting rod leaves an inner cavity of a lifting rod, the lifting rod loses fixed limiting, and then the lifting rod can be moved upwards, so that the spraying height of the hard pipe is adjusted, concrete of different heights is subjected to spraying maintenance, and the practicability of the device is improved; the situation that the maintenance effect is poor due to the fact that concrete at the high position cannot be sprayed is avoided, and the defects existing in the prior art are overcome through the technical scheme. 本实用新型涉及混凝土养护技术
