[0021] As Figures 1-5 As shown in a kind of cabinet door lock that can indicate switch state, including lock seat 1, lock shell 2, lock cylinder 3, lock tongue assembly 5, lock shell 2 is connected rod shape, including fixed part 22 and connecting rod part 23, fixed part 22 is fixed to lock seat 1, lock tongue assembly 5 is connected with fixed part 22, lock cylinder 3 is located at the connecting rod part 23 of lock shell, lock seat 1 is equipped with the push button 4 that cooperates with lock shell 2, lock cylinder 3 side wall is equipped with first tooth groove 31, lock shell 2 inside is equipped with indicating gear 6, indicating gear 6 is engaged with first tooth groove 31, indicating gear 6 is equipped with indicating mark 61, lock shell 2 surface is equipped with view hole 21 corresponding indicating mark, lock cylinder 3 rotates and will drive indicating gear 6 to rotate correspondingly, the rotation condition of lock cylinder can be directly understood through the observation view hole 21, thereby can judge the rotation condition of the lock tongue, and it is convenient and intuitive, and it is convenient to use.
[0022] In this embodiment, a mounting slot is provided on the lock base 1, and the lower end of the push button 4 is hingedly connected to the mounting slot. A limiting slider 8 for limiting the push button 4 is provided in the mounting slot. The limiting slider 8 has a limiting slot 81 that cooperates with the lock cylinder. After the corresponding key is inserted into the lock cylinder 3, the limiting protrusion 32 at the lower end of the lock cylinder will pop out and limit itself in the limiting slot 81. At this time, rotating the lock cylinder 3 will drive the limiting slider 8 to rotate, thereby releasing the limit of the push button 4. The push button 4 can be pushed to lift the lock housing 2 to unlock. Furthermore, a spring 7 is provided between the push button 4 and the mounting slot. The upper end of the spring 7 presses against the push button 4, and the lower end presses against the bottom of the mounting slot, providing elastic restoring force for the push button 4 to return to its original position.
