Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a straining device that grinds and purees various cooking materials such as potatoes and boiled eggs.

[Prior Art] According to the utility model registration application filed at the same time, the applicant has determined that the rotating shaft to which the pressing member is attached can be slidably supported in the axial direction. We proposed a straining device in which a handle member is rotatably provided between the strainer and the strainer. That is, when the handle member is rotated and pushed down from the upper position to the horizontal position, the rotating shaft is pushed down by the pressing portion that comes into contact with the upper end of the shaft, allowing the pressing member to crush the cooking material. In this case, since the rotating shaft is pushed down at its center, it is possible to avoid applying extra stress in a direction other than the axial direction to the support shaft that slidably supports the rotating shaft. It has the characteristics of being able to efficiently grind cooking ingredients with a small force, and also reducing wear on the support shaft and improving durability.

[Problems to be solved by the invention] In order to enable the pressing part to push down the rotating shaft, the straining device having the above-mentioned structure has the pressing part thrust into the support shaft as the handle is rotated. There is. As a structure for making this plunge possible, a structure is formed in the upper part of the support shaft with an axial length corresponding to the movement stroke of the rotary shaft, and the pressing part can be thrust into the groove. There is. However, in such a structure, when attaching the attaching portion to the support shaft, the pressing portion must be positioned so that it can enter into the groove, making the attaching work time-consuming.

[Purpose of the invention] In view of the above-mentioned conventional drawbacks, the purpose of the invention is to
It is an object of the present invention to provide a handle attachment structure for a straining device that can easily attach a handle to a support shaft that supports a rotating shaft so as to be slidable in the axial direction, and can improve workability.

Another object of the present invention is to provide a handle mounting structure for a strainer that allows easy removal of the handle from the support shaft.

[Means for Solving the Problems] Therefore, the present invention includes a container body having a straining mesh attached to the bottom opening, a lid that covers the top opening of the container body, and a lid that is rotatable with respect to the lid. a support shaft supported by the support shaft and having a hollow portion; the support shaft is slidable in the axial direction within the hollow portion of the support shaft and is prevented from rotating;
A rotating shaft having a pressing member on the outer periphery of the lower part, and a base end rotatably supported by a support part, which rotates the supporting shaft in a desired direction and abuts against the upper end of the rotating shaft to press it in the axial direction. In the straining device, the strainer is attached to the support shaft, and when the handle member is attached to the support shaft, the support shaft is rotated by a predetermined amount of rotation, so that the strainer is attached to the support shaft. A handle mounting structure of the strainer is composed of a groove portion that allows the pressing portion to enter into the support shaft, and a positioning engagement member that positions the handle member with respect to the support shaft.

[Operation of the invention] Since the invention is configured as described above, when the handle member is attached to the upper part of the support shaft and the support shaft is rotated by the required rotation amount by the positioning engagement member, The pressing portion of the handle member is positioned with respect to the groove portion of the support shaft, and the support shaft and the handle member are engaged. This allows the pressing part to push into the groove during the process of crushing cooking ingredients, and as the handle member is rotated in the vertical direction, the rotating shaft is pushed down by the pressing part to the downward axis line, and the pressing member It makes it possible to press cooking ingredients. Further, since the handle member is prevented from rotating due to the engagement between the support shaft and the handle member, the handle member and the support shaft can rotate together, thereby making it possible to grind the cooking ingredients. On the other hand, when the positioning engagement member is rotated in the opposite direction in the above state, the engagement of the handle member with the support shaft is released and a mismatched state is created in which it is impossible for the pressing part to enter into the groove. Ru. This allows the handle member to be removed from the support shaft.
