Line-controlled type loose-prevention bath tub water drainage device

Abstract

A line-controlled type loose-prevention bath tub water drainage device includes: a water exit component, including a water blocking plug, an insertion rod, a hollow bolt, a sieve basket, a first rotation axis, a first control rod, and a poking rod; a control valve, including a rotation button, a water overflow pad, a water overflow cover, a water overflow bend, a second control rod, and a second pull rod; a water drainage tube; and a braking line. The first control rod includes a first rotation axis and a first pull rod, the first pull rod is connected vertically to one end of the first rotation axis. The second control rod includes a second rotation axis and a second pull rod, the second pull rod is connected vertically to one end of the second rotation axis.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a water drainage device, and in particular to a line-controlled type loose-prevention bath tub water drainage device.[0003]2. The Prior Arts[0004]In general, a bath tub water exit device is composed of a water overflow portion, a water exit portion, a breaking line, and pipelines connected in between. In the existing line-controlled type bath tub water exit device, the water exit portion controls the open or close of the water exit through a spring plate fastened to the control rod. In application, the friction between the control rod and the spring plate tends to wear off the control rod, thus leading to the failure of the line-controlled function. In addition, the spring plate is liable to have metal fatigue and tends to deform, hereby also leading to the failure of its line-controlled function. In case the water pressure becomes too great, in the water exit process of the water blocki...

AI Technical Summary

Benefits of technology

The present invention provides a line-controlled type loose-prevention bath tub water drainage device to prevent the wearing off of the control rod and prolong the service life of the device. The device includes a first position limiting slot and a second position limiting slot to restrict the position of the second end of the braking line, ensuring stable water exit operation. The control valve is capable of blocking the rotation of the second pull rod during water exit, preventing the rebound of the water blocking plug and closing the water exit hole, thereby effectively preventing the wearing off of the control rod.

Problems solved by technology

In application, the friction between the control rod and the spring plate tends to wear off the control rod, thus leading to the failure of the line-controlled function.

In addition, the spring plate is liable to have metal fatigue and tends to deform, hereby also leading to the failure of its line-controlled function.

In case the water pressure becomes too great, in the water exit process of the water blocking plug, the spring plate tends to rebound, causing the automatic closing of the water blocking plug, so that water can not be exited and discharged.

In case the line-controlled bath tub water exit function fails to work, then the bath tub can not be used by a user to take a bath.

Also, since the water exit device is installed in the bottom seat of the bath tub, its maintenance and replacement is rather difficult and cumbersome.

Therefore, presently, the design and performance of the bath tub water drainage device is not quite satisfactory, and it leaves much room for improvement.
