Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the case of the example 1, the following examples are given,

please refer to fig. 1-5, in an embodiment of the present invention, a driving rod self-locking reset device for a fire window, includes a lock body 9 fixed on a window frame and a driving rod 1 fixed on the window frame, the lock tongue 91 is fixedly connected to the outside of the lock body 9, a notch 10 is disposed at a position of the driving rod 1 close to the lock tongue 91, a lock catch 3 and a connecting piece 4 are mounted on the upper and lower end faces of the notch 10, a rivet 5 for fixing the lock catch 3 and the connecting piece 4 is disposed on the outside of the notch 10, a hanging buckle 11 is disposed on one side of the lock body 9 far from the notch 10, a limit buckle 41 is disposed on one side of the connecting piece 4, a spring 6 is disposed on the end face of the lock body 9, pull rings 61 are integrally connected to both sides of the spring 6, a pull ring 61 on one side of the spring 6 is hung on the limit buckle 41, and a pull ring 61 on the other side is hung on the hanging buckle 11.

In this embodiment, the latch 3 and the connecting plate 4 correspond to the notch 10 on the rod body 1, and are riveted by the rivet 5, the pull ring 61 on one side of the spring 6 is hung on the limit buckle 41 at one end of the connecting plate 4, and the pull ring 61 on the other side is hung on the hanging buckle 11.

When the latch 3 moves, the spring 6 can pull it to reset.

When the window sash is closed by external force, the lock catch 3 and the lock tongue 91 are automatically buckled; when the transmission rod moves upwards, the lock catch 3 slides to the position above the bolt 91, and the spring 6 is stretched; when the window is opened, the lock catch 3 is separated from the lock tongue 91, and the spring 6 drives the lock catch 3 to reset.
