The invention relates to the technical field of door locks and in particular to a manual unlocking structure for a door lock. The manual unlocking structure comprises an inner panel, an outer panel and a lock body. A manual unlocking control mechanism used for manual control unlocking operation is arranged in the inner panel. In use, a user can naturally use the thumb of one hand for pressing a handle key and then pressing an inner handle downwards, the inner handle drives a square rod to rotate to control the lock body to be unlocked, a door is opened, and the structure is quite convenient to use. Due to the adoption of two square rods, the square rod of the inner panel only moves in the inner panel, the assembled square rod of the outer panel does not move inwards or outwards relative to the lock body and the like, the square rod of the inner panel receives small resistance when the handle key moves, and the situation that friction force is large and the handle key is difficult to reset due to oblique installation can be avoided.
