[0022] A limit latch device for a distribution box door includes a box body 1, a hinge 2 is provided at the port of the box body 1, a door panel 3 is installed at one end of the hinge 2, a sealing gasket 4 is installed on the inner wall of the door panel 3, and a limit latch assembly 5 is installed on the inner wall of the box body 1.

[0023] In this embodiment, please refer to Figure 1 , Figure 2 and Figure 3 The limiting buckle assembly 5 includes a mounting base plate 501 and a fixing plate 502. The mounting base plate 501 is installed on the inner wall of the housing 1. A limiting groove 503 is opened on the outer wall of the mounting base plate 501. A limiting slider 504 is slidably connected to the inner wall of the limiting groove 503. A connecting rod 505 is installed on the outer wall of the limiting slider 504.
