Example 1

Referring to FIGS. 1 to 3 , an embodiment of the present invention provides a lint filter clipping device, which is used to install the lint filter on a washing machine.

The clamping device includes two elastic arms 10 , one end of the two elastic arms 10 is connected, and the other ends are arranged at intervals, thereby forming a clamping opening between the two elastic arms 10 . By pressing one elastic arm 10, the two elastic arms 10 can be brought close to each other, and the lint filter can be installed and removed.

The two elastic arms 10 can be arranged in parallel or at an included angle. If the two elastic arms 10 are parallel, one side of the two elastic arms 10 is connected by a connecting piece. The two elastic arms 10 can be integrally formed, that is, formed by bending one elastic plate several times. The shape of the clamping device is not limited here, and may be U-shaped, triangular or trapezoidal as shown in the figure.

A limiting portion is provided between the other ends of the two elastic arms 10 , which can selectively prevent the two elastic arms 10 from approaching each other. During installation and disassembly, the limiter does not work. By pressing one elastic arm 10, the two elastic arms 10 can be brought close to each other, and the lint filter can be installed and disassembled; during use, the limiter restricts The two elastic arms 10 are close to each other. When one elastic arm 10 is pressed, the limiting part will give the elastic arm 10 a resistance in the opposite direction of the pressing force, thereby preventing the clamping device from loosening under the action of external force and preventing the lint filter fall off. Of course, there is an upper limit on the bearing force of the limiting portion. If the external force on the elastic arm 10 is too large and exceeds the maximum force that the limiting portion can bear, the clamping device may be deformed excessively and damaged.

One end of the limiting portion is connected to one elastic arm 10 , and the other end of the limiting portion can selectively abut with another elastic arm 10 . During installation and disassembly, the limiting portion does not abut with another elastic arm 10, and does not affect the two elastic arms 10 approaching each other; during use, the limiting portion can abut with another elastic arm 10, limiting the two The elastic arms 10 are close to each other.

In this embodiment, the limiting portion includes a rotating member 11 , one end of the rotating member 11 is rotatably connected to one elastic arm 10 , and the other end of the rotating member 11 selectively abuts with another elastic arm 10 . The rotating member 11 has at least two states, namely the installation state and the use state. In the installed state, the rotating member 11 does not abut with another elastic arm 10, and does not affect the two elastic arms 10 approaching each other, so that the lint filter can be performed. In the use state, the rotating member 11 can be in contact with the other elastic arm 10, when one elastic arm 10 is pressed against the rotating member 11, the rotating member 11 restricts the two elastic arms 10 to approach each other. In this embodiment, the rotating member 11 is rotated from the installation state to the use state, and the rotation angle is 90 degrees.

The rotating member 11 is connected with the elastic arm 10 through the rotating shaft 13 . The rotating member 11 is passed through the rotating shaft 13 , and the rotating shaft 13 is rotatably arranged on the elastic arm 10 . Alternatively, the rotating shaft 13 is provided on the rotating member 11 , the elastic arm 10 is provided with mounting holes matched with both ends of the rotating shaft 13 , and the rotating shaft 13 is rotatably connected with the mounting holes. Of course, the rotating member 11 can also be rotatably connected to the elastic arm 10 through a ball head, so that the rotating member 11 can be rotated in any direction to the use state. In this embodiment, the rotating member 11 is a rod. In the installed state, the extending direction of the rotating member 11 is parallel to the surface of the elastic arm 10 . In the use state, the extending direction of the rotating member 11 is perpendicular to the surface of the elastic arm 10 .

In order to make the rotating member 11 function well in the use state, the end of the rotating member 11 is provided with an arc surface, the arc surface is provided with a protrusion, and the elastic arm 10 is provided with a groove matching with the protrusion. When the rotating member 11 is rotated from the installation state to the use state, the protrusions are inserted into the grooves, which play a certain position limiting effect on the rotating member 11 and prevent the rotating member 11 from shifting during use. Only when a certain rotational force is applied to the rotating member 11 can the protrusion and the groove be snap-fitted.

The limiting portion further includes a connecting piece 12 , the connecting piece 12 is fixedly connected with the other elastic arm 10 , and the rotating piece 11 selectively abuts against the connecting piece 12 . The arrangement of the connecting piece 12 shortens the distance between the rotating piece 11 and the other elastic arm 10 , thereby shortening the length of the rotating piece 11 and increasing the structural strength of the rotating piece 11 .

Both the rotating member 11 and the connecting member 12 have limit surfaces, and the two limit surfaces can abut. In the use state, the limiting surface of the rotating member 11 faces the limiting surface of the connecting member 12 . When one elastic arm 10 is pressed, the two limiting surfaces can abut, thereby restricting the two elastic arms 10 from approaching each other.
