The present invention relates to a basin accessory, and more particularly to a pop-up drain stopper linkage assembly adapted for the basin.
A conventional pop-up drain stopper linkage assembly is disclosed in U.S. Pat. No. 8,136,179 B2 and contains: a lift rod fixed on a basin on which a faucet is mounted and configured to be pulled upward and pressed downward; a drain base screwed with a bottom of the basin and cooperating with a screwing element, the draining base including an outlet defined on a top thereof and a through hole formed on a peripheral side thereof; a connector connected with the through hole of the drain base; a coupling rod retained with a bottom of the lift rod and moving vertically in response to the lift rod, the coupling rod including a plurality of orifices formed thereon; a driving rod including a first segment, a second segment, and a spherical ball adjacent to the first segment and rotatably connected with the connector so as to form a fulcrum, wherein the first segment extends into the drain base from the through hole, the driving rod also includes plural fitting portions arranged proximate to the second segment, and one of the plural fitting portions selectively fits with one of the plurality of orifices on the coupling rod, such that the driving rod moves upward and downward in response to the coupling rod and causes a lever movement along the fulcrum; a drain stopper including a bottom end retaining with the first segment of the driving rod from the outlet of the drain base, and the drain stopper moving upward and downward in response to the lever movement of the driving rod, wherein the drain stopper moves downward, the outlet of the drain base is turned off, and when the drain stopper moves upward, the outlet of the drain base is turned off.
However, the coupling rod is removed from and is fitted with the first segment of the driving rod repeatedly, thus fixing the conventional pop-up drain stopper linkage assembly under the basin troublesomely.
A distance exits between any two adjacent orifices on the coupling rod, so the first segment of the driving rod cannot be adjustably moved on the coupling rod.
The driving rod selectively retains with the one of the plurality of orifices on the coupling rod by using the plural fitting portions, and a protrusion of any two adjacent fitting portions resists against the plurality of orifices, thus adjusting the driving rod difficultly.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
One aspect of the present invention is to provide a pop-up drain stopper linkage assembly which is fixed under the basin quickly and exactly, and a drain stopper moves upward or downward as a lift rod is pulled upward or is pressed downward, thus turning on/off an outlet of a drain base.
To obtain the above aspect, a pop-up drain stopper linkage assembly provided by a first embodiment of the present invention contains: a lift rod, a drain base, a connector, a threaded rod, a threaded sleeve, a driving rod, and a drain stopper.
The lift rod extends through a basin, and the lift rod is pulled upward or is pressed downward and is rotated by a user after extending through the basin.
The drain base is disposed on the basin and including an outlet.
The connector is fixed on the drain base.
The threaded rod includes a top end connected with a bottom end of the lift rod, and the threaded rod moves upward and downward and rotating in response to the lift rod.
The first threaded sleeve is configured to screw with the threaded rod and to move upward and downward along the threaded rod in response to a rotation of the threaded rod, the first threaded sleeve includes a first retaining portion formed on an outer wall thereof.
The fixing holder includes an aperture and a second retaining portion arranged on an outer wall thereof so as to retain with the first retaining portion.
The second threaded sleeve rotatably connects with the aperture of the fixing holder.
The driving rod includes a first segment, a second segment, a spherical ball formed adjacent to the first segment and rotatably connecting with the connector so as to form a fulcrum, and a screwing extension arranged proximate to the second segment so as to screw with the second threaded sleeve, such that the second threaded sleeve is rotated to move along the screwing extension, and the driving rod causes a lever movement along the fulcrum as the threaded rod moves upward and downward.
The drain stopper is secured on the drain base and includes a bottom end moving upward and downward in response to the lever movement of the driving rod, such that the outlet of the drain base turns on/off as the bottom end of the drain stopper moves upward and downward respectively.
In addition, a pop-up drain stopper linkage assembly provided by a second embodiment of the present invention contains: a lift rod, a drain base, a connector, a threaded rod, a first threaded sleeve, affixing holder, a second threaded sleeve, a driving rod, and a drain stopper.
The lift rod extends through a basin, and the lift rod is pulled upward or is pressed downward and is rotated by a user after extending through the basin.
The drain base is disposed on the basin and includes an outlet.
The connector is fixed on the drain base.
The threaded rod includes a top end connected with a bottom end of the lift rod, and the threaded rod moves upward and downward and rotates in response to the lift rod.
The first threaded sleeve is configured to screw with the threaded rod and to move upward and downward along the threaded rod in response to a rotation of the threaded rod, the first threaded sleeve includes a first retaining portion formed on an outer wall thereof.
The fixing holder includes an aperture and a second retaining portion arranged on an outer wall thereof so as to retain with the first retaining portion.
The second threaded sleeve rotatably connects with the aperture of the fixing holder.
The driving rod includes a first segment, a second segment, a spherical ball formed adjacent to the first segment and rotatably connecting with the connector so as to form a fulcrum, and a screwing extension arranged proximate to the second segment so as to screw with the second threaded sleeve, such that the second threaded sleeve is rotated to move along the screwing extension, and the driving rod causes a lever movement along the fulcrum as the threaded rod moves upward and downward.
The drain stopper is secured on the drain base and includes a bottom end moving upward and downward in response to the lever movement of the driving rod, such that the outlet of the drain base turns on/off as the bottom end of the drain stopper moves upward and downward respectively.
With reference to
The lift rod 10 extends through the basin 2, and wherein when a faucet is mounted on the basin 2, the lift rod 10 also extends through the faucet, such that the lift rod 10 is pulled upward or is pressed downward and is rotated by a user after extending through the basin 2 or the faucet.
The drain base 20 is disposed on the basin 2 and includes an outlet 21.
The connector 30 is fixed on the drain base 20. In this embodiment, the connector 30 includes a body 31, a cap 32 screwing with the body 31, and two washers 33 matching with the body 31 and the cap 32 respectively, wherein the body 31 is rotatably retained with the drain base 20.
As shown in
As illustrated in
The driving rod 60 includes a first segment 61, a second segment 62, a spherical ball 63 formed adjacent to the first segment 61 and rotatably connecting with the connector 30 so as to form a fulcrum, and plural second retaining portions 64 horizontally arranged proximate to the second segment 62 so that the first retaining portion 51 of the threaded sleeve 50 selectively retains with one of the plural second retaining portions 64, such that the driving rod 60 causes lever movement along the fulcrum as the threaded rod 40 moves upward and downward.
The spherical ball 63 is limited and rotates between the two washers 33 of the connector 30.
In this embodiment, each of the plural second retaining portions 64 is a locking hole so that the spherical surface 511 of the column selectively retains with the one of the plural second retaining portions 64. Preferably, the column rotates relative to the one of the plural second retaining portions 64, hence the threaded sleeve 50 moves upward and downward along the threaded rod 40 and is not limited by the driving rod 60.
The drain stopper 70 is secured on the drain base 20 and includes a bottom end moving upward and downward in response to the lever movement of the driving rod 60, such that the outlet 21 of the drain base 20 turns on/off as the bottom end of the drain stopper 70 moves upward and downward respectively.
