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.

What is claimed is: 
     
         1 . A line-controlled type loose-prevention bath tub water drainage device, comprising:
 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,   wherein, 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, while the other end of the first rotation axis is connected to and drives the poking rod, the water blocking plug and the poking rod are disposed on a water exit port, the poking rod is connected to and drives a first control rod, while the first control rod is connected to the first end of the breaking line,   wherein, 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, while the rotation button is connected to and drives the other end of the second rotation axis, the rotation button is connected to and drives a second control rod, while the second control rod is connected to and drives the second end of the breaking line, on the water overflowing bend is provided with a first position limiting slot, while the second pull rod is disposed in the first position limiting slot, in the first position limiting slot is provided with a position limiting piece restricting the rotation angle of the second pull rod.   
     
     
         2 . The line-controlled type loose-prevention bath tub water drainage device as claimed in  claim 1 , wherein a distance between the second pull rod and the first side wall of the first position limiting slot is less than a length of the second pull rod, such that the first side wall of the first position limiting slot is a position limiting piece. 
     
     
         3 . The line-controlled type loose-prevention bath tub water drainage device as claimed in  claim 1 , wherein the position limiting piece is a protrusion block in the first position limiting slot. 
     
     
         4 . The line-controlled type loose-prevention bath tub water drainage device as claimed in  claim 3 , wherein the first position limiting slot is further connected and in communication with a second position limiting slot, used to restrict a position of a second end of the braking line, the second position limiting slot is located below the first position limiting slot, and is close to the first side wall of the second position limiting slot. 
     
     
         5 . The line-controlled type loose-prevention bath tub water drainage device as claimed in  claim 4 , wherein the first position limiting slot is of a rectangular structure, while the second position limiting slot is connected below the first position limiting slot, and is close to a corner angle of the first side wall. 
     
     
         6 . The line-controlled type loose-prevention bath tub water drainage device as claimed in  claim 5 , wherein the first control rod and the first pull rod are located on a same side of the first rotation axis, and are located facing away from each other. 
     
     
         7 . The line-controlled type loose-prevention bath tub water drainage device as claimed in  claim 6 , wherein above the water exit port is provided with a sieve basket, while a central portion of the sieve basket is provided with threads used to connect the hollow bolt, to allow the insertion rod of the water blocking plug to be inserted into an inner hole of the hollow bolt.
