The connecting member 13 is threadedly connected to the adjusting member 12, and the rotation of the adjusting member 12 causes the lock rod 11 and the connecting member 13 to move closer to or away from each other. Thus, when the lock rod 11 and the connecting member 13 move closer to each other, the lock tongues 40 at the upper and lower ends of the cabinet door lock 100 are driven to move closer to each other, that is, the length of the cabinet door lock 100 is shortened. Similarly, when the lock rod 11 and the connecting member 13 move away from each other, the lock tongues 40 at the upper and lower ends of the cabinet door lock 100 are driven to move away from each other, that is, the length of the cabinet door lock 100 is increased.

[0059] In some preferred embodiments, the adjusting member 12 is a sleeve with an internal thread. The cabinet door lock 100 further includes a locking nut 50, which is screwed to the locking rod 11 and / or the connecting member 13 and is fastened to the end surface of the adjusting member 12 to limit the rotation of the adjusting member 12.
