Abstract
The utility model discloses a joint lock enabling doors to be closed sequentially. The joint lock comprises a tension spring, a sliding baffle and a support used for fixation. A sliding groove is formed in the sliding baffle. A fixing shaft is arranged on the support. The fixing shaft is arranged inside the sliding groove. One end of the tension spring is fixed to the sliding baffle. The other end of the tension spring is arranged on the fixing shaft. The sliding baffle is provided with a blocking sheet, wherein a lock hole is covered with the blocking sheet. The joint lock is installed at the lap joint position of a left door and a right door of a switch cabinet cable chamber, the left door pushes the sliding baffle to move so that the blocking sheet which the lock hole is covered with on the sliding baffle can be moved away, a latch on the right door of a switch cabinet can be inserted into the lock hole to make the right door be closed only at this time, and therefore the latch on the right door can be locked and the right door can be closed completely only when the left door is closed.
