Description

Technical Field

[0001] The present invention relates to the technical field of basin accessories, and in particular to a basin drainer. Background Art

[0002] The basin drain is a device for being installed at the bottom of the basin and used for drainage. The basin drain currently on the market includes a shell assembly, a plug assembly, a bracket, a traction line, a cable and a connecting pipe. The bracket is fixed to the inside of the shell assembly, and a drainage channel is formed between the bracket and the shell assembly. The plug assembly is arranged at the water inlet at the upper end of the shell assembly. The traction line is movably passed through the bracket. The upper end of the traction line is connected to the plug assembly. The lower end of the traction line extends out of the bracket and the shell assembly and is fixed with a first connecting head. One end of the pull line in the cable is fixed with a second connecting head, one end of the outer sleeve in the cable is connected to one end of the connecting pipe, and the other end of the connecting pipe is connected to the bracket. The other end of the pull line is used to be connected to the driving end in the push-pull assembly, and the other end of the outer sleeve is used to be fixed to the outer shell in the push-pull assembly; in addition, the first connecting head and the second connecting head are both located at the connecting pipe. The interior and the first connector is connected to the second connector; when the push-pull assembly pulls the pull wire, the pull wire can pull the traction wire and the plug assembly to make the plug assembly block the water inlet, and when the push-pull assembly pushes the pull wire, the pull wire can push the traction wire and the plug assembly to make the plug assembly release the blockage of the water inlet; however, in the above structure, since the traction and pushing of the pull wire are achieved by the push-pull assembly, and the push-pull assembly in the prior art has the disadvantage of large size, so after the push-pull assembly is installed on the table, there is a disadvantage of poor aesthetics. In addition, after the push-pull assembly pulls the pull wire and the pull wire pulls the traction wire and the plug assembly to make the plug assembly block the water inlet, since the push-pull assembly itself does not have a self-locking structure, the traction wire and the pull wire are easily affected by the pull-back force of the plug assembly and move back, which in turn affects the sealing effect of the plug assembly on the water inlet. Summary of the Invention

[0034] When using the present invention, when the button in the automatic ballpoint pen pressing assembly is pressed to cause the automatic ballpoint pen pressing assembly to pull the pull wire, the pull wire can pull the traction wire and the plug assembly to cause the plug assembly to block the water inlet, and when the button in the automatic ballpoint pen pressing assembly is pressed again to cause the automatic ballpoint pen pressing assembly to push the pull wire, the pull wire can push the traction wire and the plug assembly to cause the plug assembly to release the blockage of the water inlet; in the above-mentioned process of pressing the button in the automatic ballpoint pen pressing assembly, when the button is pressed, the driving end of the automatic ballpoint pen pressing assembly can pull the pull wire, and when the button is pressed again, the driving end of the automatic ballpoint pen pressing assembly can push the pull wire. This structure is the same as the button structure at the tail end of the automatic ballpoint pen, which is the existing technology, so it will not be repeated here.

[0035] The foregoing is merely an embodiment of the present invention and is not intended to limit the present invention. It will be apparent to those skilled in the art that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are intended to be included within the scope of the claims of the present invention.
