Auxiliary door lock
The invention aims at providing an auxiliary door lock which is compact in structure, reasonable in design and capable of carrying out limiting operation on an auxiliary lock. The auxiliary door lockcomprises a shell, and a spring bolt hole is formed in one side of the shell. A lock head pulling support is rotationally mounted in the shell, and a first hook and a second hook are arranged at the two ends of the shell in a longitudinal sliding manner. The first hook and the second hook each has a locking position extending outwards and an unlocking position retracting inwards. The lock head pulling support and the first hook are lined through a first linkage sheet, and the first hook and the second hook are linked through a second linkage sheet. A second elastic part capable of making the first hook to reset and pop out to the locking position is arranged on the first hook. The first hook comprises a first hook body and a straight rod part, and the straight rod part is arranged in the shell in a longitudinal sliding manner. The first hook is integrally formed at the outer end of the straight rod part, and the inner end of the straight rod part is a limiting end.
