[0010] Preferably, the inner wall of the outer casing is provided with a ratchet plate located below the thread, and the upper end of the ratchet plate is provided with ratchet teeth, and the lower end of the flange of the inner sleeve is provided with a section of teeth that are adapted to the ratchet teeth of the ratchet plate.

[0011] Preferably, the overflow drain head further includes an inner plate and a decorative plate. The inner plate is provided with a locking groove near both ends, and the locking groove cooperates with the locking seat on the decorative plate for locking.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model, by setting an outer shell and an inner sleeve, forms a height difference between the lower end of the inner sleeve and the overflow water inlet and outlet, thus preventing odors with a water seal. The drain pipe has a compact structure and occupies little installation space, making it suitable for installation in small spaces at the bottom of the bathtub.

[0014] 2. This utility model, by setting a ratchet plate and toothed engagement, prevents the inner sleeve from rotating due to the thread and ratchet / toothed engagement between the inner sleeve and the outer sleeve, thus preventing the inner sleeve from rotating due to the lateral impact of overflowing water and the lower end of the inner sleeve from rising and losing the water seal effect.

[0015] 3. This utility model features an overflow drain head with an interlocking structure between the inner panel and the decorative panel, which facilitates the replacement of the decorative panel. Attached Figure Description
