In one use, the first ratchet and the second ratchet are each provided with 4, and the tooth tips of the first ratchet and the second ratchet are staggered, which can be a 45° angle formed by the tooth tips of the first ratchet and the second ratchet; a first spring 32 is arranged between the water stop plug and the movable shaft, and a second spring 52 is arranged between the water stop plug and the main body; a clamping block 33 is provided at the lower end of the movable shaft, and when the clamping block is abutted with the hook, the water stop plug blocks the drain pipe, and at this time the hook hooks the clamping block, so that the water stop plug cannot move upward, and when the clamping block is misaligned with the hook, the clamping block cooperates with the interval, and the water stop plug can move axially (upward) with the drain pipe under the action of the second spring, so that the drain pipe can drain.
[0026] Preferably, a water-stop sealing ring 23 is provided on the outer periphery of the water-stop plug, and the water-stop sealing ring can be sealed with the inner peripheral wall of the drain pipe; when the clamping block and the clamping hook are in abutment with each other, the water-stop sealing ring and the inner peripheral wall of the drain pipe maintain a sealed fit, and when the clamping block and the clamping hook are misaligned, the water-stop sealing ring is separated from the inner peripheral wall of the drain pipe. For details, please refer to the drawings in the specification. Figure 1 , Figure 2 .
[0027] Furthermore, a first connecting hole 24 is provided in the middle of the water stopper, the movable shaft is inserted in the first connecting hole, and a first spring that can cooperate with the movable shaft is provided in the first connecting hole. A plug hole 25 is also provided at the lower end of the water stopper, a plug 40 is inserted in the plug hole, a cavity is formed between the plug and the plug hole, a second connecting hole 42 that can be coaxial with the first connecting hole and the plug hole is provided on the plug, the movable shaft can be inserted in the second connecting hole, the first ratchet is provided on the upper end surface of the plug hole, and the second ratchet is provided on the upper end surface of the plug.

At the same time, under the action of the second spring, the plug and the water stop plug are guaranteed to perform synchronous axial movement.
[0029] In order to limit the water stopper and the body, a guide groove 27 is provided on the side wall of the water stopper located in the body, and a threaded hole 53 is provided on the body. A screw 54 is provided in the threaded hole. The screw can extend into the guide groove to limit the axial travel of the water stopper.
[0030] Preferably, the inner wall of the drain pipe is provided with a step surface 11, and the bottom end of the main body can abut against the step surface. The outer periphery of the main body is annularly arranged with ribs 55 that can cooperate with the inner wall of the drain pipe. The ribs can block hair to prevent the drain pipe from being blocked by the hair. At the same time, there is a channel for water to pass between the main body and the inner wall of the drain pipe.
[0031] Furthermore, the body further comprises an outer ring 56 located on the outer peripheral side of the rib, and the bottom end of the outer ring can abut against the step surface. The utility model can be provided with a seal at the matching position of the parts, which will not be elaborated again.
[0032] To be more specific, the utility model: the water stop plug is pressed by external force, and after it moves a certain stroke, the opening and closing of the drain pipe is realized through a spring rebound structure. The specific implementation method is as follows: the water stop plug is pressed, and the clamping block of the movable shaft presses against the lower end surface of the main body. When the pressure continues, the first spring is also compressed, and the pin shaft of the movable shaft is guided by the first ratchet on the water stop plug, so that the movable shaft rotates horizontally by about 45°, and the water stop plug and the main body are in contact and pressed without moving; after releasing the hand, it rebounds through the second spring, and the first spring also rebounds during this period, so that the pin shaft of the movable shaft hits the second ratchet, and the movable shaft rotates horizontally again by about 45°. At this time, the clamping block disengages from the hook and cooperates with the interval. Under the action of the second spring, the water stop plug and the water stop sealing ring bounce off the drain pipe as a whole to realize drainage.
[0033] The above description shows and describes the preferred embodiments of the utility model. As mentioned above, it should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the utility model concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not depart from the spirit and scope of the utility model, and should be within the scope of protection of the claims attached to the utility model.
