Some embodiments of the present utility model are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without collision.

Referring to fig. 1 to 4, a waterproof plug 100 for plugging a drain is provided in an embodiment of the present utility model. The waterproof plug 100 includes a stopper portion 10, a plug rod 20, and a sealing portion 30. One end of the plunger 20 is connected to the limiting portion 10, and the other end of the plunger 20 extends in a direction away from the limiting portion 10. The seal portion 30 is provided on the outer peripheral wall of the plunger 20. The sealing portion 30 includes a first surface 31 and a second surface 32, the first surface 31 and the second surface 32 are disposed opposite to each other along an axial direction of the plunger 20, wherein the first surface 31 is disposed opposite to the stopper portion 10, and the second surface 32 is disposed opposite to the stopper portion 10. The seal portion 30 is flexible and is capable of swinging relative to the plunger 20 to switch between a first state or a second state. When the sealing portion 30 is in the first state, the second surface 32 is located between the first surface 31 and the insert pin 20, that is, the first surface 31 is located radially outward of the second surface 32, and an included angle between the second surface 32 and the outer circumferential surface of the insert pin 20 is an acute angle; when the sealing portion 30 is in the second state, the first surface 31 is located between the second surface 32 and the insert pin 20, that is, the second surface 32 is located radially outward of the first surface 31, and an included angle between the first surface 31 and the outer peripheral surface of the insert pin 20 is an acute angle.

When in use, the plug rod 20 is inserted into a water outlet to be plugged by controlling the limiting part 10, wherein the radial dimension of the drain opening is smaller than the radial dimension of the sealing portion 30. In the process of inserting the insert rod 20, since the radial dimension of the sealing part 30 is larger than the radial dimension of the drain opening, the sealing part 30 can be blocked by the cross section of the opening of the drain opening or the friction of the inner wall of the drain opening to swing to the first state, so that the first surface 31 can be contacted with the inner wall of the drain opening to enlarge the contact area between the insert rod 20 and the inner wall of the drain opening, and the sealing part 30 swinging to the first state can be extruded by the inner wall of the drain opening in the drain opening, so that the first surface 31 is tightly attached to the inner wall of the drain opening under the action of the elastic restoring force of the sealing part 30, and the sealing effect between the insert rod 20 and the inner wall of the drain opening is improved.

Similarly, in the process of pulling out the insert rod 20, since the radial dimension of the sealing portion 30 is greater than the radial dimension of the drain opening, the sealing portion 30 is rubbed by the inner wall of the drain opening and swings reversely to the second state, so that the second surface 32 can be contacted with the inner wall of the drain opening to increase the contact area between the insert rod 20 and the inner wall of the drain opening, and the sealing portion 30 swinging to the second state is extruded by the inner wall of the drain opening in the drain opening, so that the second surface 32 is tightly attached to the inner wall of the drain opening under the action of the elastic restoring force of the sealing portion 30, and the sealing effect between the insert rod 20 and the inner wall of the drain opening is improved.

In addition, no matter in the process of inserting or extracting the inserted link 20, when the inner wall of the water outlet is provided with a raised barrier, the sealing part 30 has flexibility, so that the first surface 31 or the second surface 32 positioned at the outer side can be concave when encountering the barrier, friction between the first surface 31 or the second surface 32 and the barrier is reduced, thereby playing a guiding role, reducing the hardness of the inserted link 20 in the process of inserting or extracting, and further achieving the purpose of improving the sealing effect and improving the inserting and extracting hand feeling.

In other embodiments, the first surface 31 and the second surface 32 may have other shapes, such as a wave-breaking surface or a honeycomb surface formed by splicing regular polygons, so as to improve flexibility or increase a contact area with an inner wall of the drain opening.

In some embodiments, the distance between the first surface 31 and the second surface 32 gradually decreases from the plunger 20 in a direction away from the plunger 20, so that the thickness of the sealing portion 30 is thinner and thinner, and thus the portion of the sealing portion 30 away from the plunger 20 is easier to deform and swing between the first state and the second state.

In some embodiments, the cross section of the insert rod 20 is the same along the axial direction of the insert rod 20, so that the gap between the insert rod 20 and the inner wall of the water outlet is small enough along the axial direction, thereby ensuring the tightness, facilitating the processing and improving the production efficiency.

In some embodiments, a guiding portion 21 is disposed at an end of the insert rod 20 away from the limiting portion 10, the cross section of the guiding portion 21 gradually decreases toward a direction away from the limiting portion 10, and the guiding portion 21 is used for guiding the end of the insert rod 20 to be inserted into the drain outlet so as to improve the feel. As an exemplary example, the guide portion 21 includes a tapered surface 211 and a spherical surface 212 that are smoothly connected, the bottom of the tapered surface 211 is connected to the end of the insert rod 20, the spherical surface 212 is connected to the top of the tapered surface 211, and the spherical surface 212 can better guide the end of the insert rod 20 to be inserted into the drain opening and avoid sharp corners of the tapered surface 211 to improve safety. In other embodiments, the guide portion 21 may be a spherical surface, a conical surface, a curved surface of another shape, or the like.
