Abstract
The invention relates to a single-head gourd lock for guarding against a universal key, the structure comprising a linking rod and a dialing wheel in the existing single-head gourd lock is changed into the structure comprising double rotating wheels and the dialing wheel, and two keys of the double rotating wheels and two grooves of an inner hole of the dialing wheel are asymmetric. When a key is inserted into a lock core, the two grooves at the tail part of the lock core can drive the two keys of the key rotating wheels, when the key is rotated to enable the two keys of the key rotating wheels to be in superposition with the positions of the two grooves of the inner hole of the dialing wheel, the key rotating wheels can be combined with the dialing wheel together under the push of the key, the dialing wheel is further driven and then the lock is opened by the dialing wheel. As the linking rod in the existing single-head gourd lock is abolished, the groove at the head part of the linking rod for being utilized by a steel wire curved hook is absent; and furthermore, a circular gasket is added in front of the key rotating wheels, thereby thoroughly preventing the possibility that a steel wire of the curved hook and various external unlocking tools skip over the lock core and directly dial the key rotating wheels. Although the universal key can rotate the lock core, the key rotating wheels can not be pushed forwards while the lock core is rotated (because the push force of a spring needs to be overcome by a greater force), and the lock can not be opened yet.
