Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Referring to FIG. 2, the present invention is set whether the locking rim 20 is rotated along the circumference of the lid body 10 to be sealed with the inner pot.

Referring to FIG. 3, in the present invention, the upper plate 32 is fixed to the upper surface of the locking rim 20, and the stopper member 30 is movable to the upper and lower portions of the locking rim 20 under the upper plate 32. It is installed in a state of being elastically supported downward by the spring 35.

Specifically, the stopper member 30 is formed with an arm 33 extending from the upper side to the lid body 10 side, the arm 33 is interfered with the locking projection 11 formed on the upper portion of the lid body 10. . On the other hand, the stopper member 30 has a lifting post 34 formed vertically downward, and the lifting post 34 is mounted to be movable up and down through the locking rim 20.

In addition, one side of the elevating post 34 is formed with a spring mounting projection 36 is fixed one end of the spring (35). Accordingly, a spring 35 is mounted on the spring mounting protrusion 36, and the upper portion of the spring mounting protrusion 36 supports the upper end of the spring 35 by the upper plate 32 fixed to the upper portion of the locking rim 20 by a bolt 31. do. Accordingly, the stopper member 30 is pressed downward by the elastic force of the spring 35 so that the elevating post 34 of the stopper member 30 protrudes to the lower surface of the locking rim 20. .

Meanwhile, referring to FIG. 7, a pair of fastening holes H are formed on the upper surface of the locking rim 20, and bolts 31a and 31b are fastened to the fastening holes H as shown in FIG. 8, respectively. The upper plate 32 is fixed. That is, the upper plate 32 is fixed on the locking rim 20 to support the elastic force of the spring 35 in the lower portion of the locking rim 20.

On the other hand, on the upper surface of the lid body 10, when the stopper member 30 is lowered, a locking protrusion 11 protruding upward is formed so that the end of the arm 33 is interfered.

Here, the locking projection 12 is formed by the inclined surface 12 on one side when the locking rim 20 is rotated in the counterclockwise direction, even if the stopper member 30 is in the lowered state, the arm of the stopper member 30 ( 33) rides over the inclined surface 12 of the locking projection 11 to enable rotation of the locking rim 20 counterclockwise.

However, in the state as shown in FIG. 4, when the locking rim 20 is rotated in the clockwise direction, the arm 35 of the stopper member 30 is locked to the tip of the locking protrusion 11 corresponding to the opposite side of the inclined surface 12. Clockwise rotation of the rim 20 becomes impossible.

This structural operation principle can be set in the operating direction for the closed lock and release of the locking rim 20 and the inner pot. That is, even when the inner pot cover 60 is separated, the rotation of the locking rim 20 in the opening direction is enabled, and the opening of the cooker lid can be set to be possible.
