[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This three-section concealed slide rail mechanism uses a support plate to install the three-section slide rail body, and a positioning plate to fix the support plate. When installing the drawer, the three-section slide rail body can be pulled out, and then the connecting plate is pushed upward to make the traction plate slide on the support rod. At this time, the traction plate will compress the elastic element, and at the same time, the top rod pushes the extension plate upward. Then, the through hole on the drawer is aligned with the extension plate, and the extension plate is inserted into the misalignment groove on the drawer. Then, the drawer is pushed to displace the extension plate from the through hole, and the connecting plate is released. At this time, the spring in the compressed state causes the traction plate to move the top rod downward under its own rebound force, which in turn causes the locking block on the bottom of the extension plate to engage with the locking groove on the misalignment groove, thus realizing the installation and fixation between the drawer and the three-section slide rail body. This utility model uses a snap-fit ​​fixing component to facilitate the assembly and fixation between the drawer and the three-section slide rail, and the operation is simple and convenient.
