Description

A multi-tap for installation for sewer traps}

The present invention relates to a power strip for installing a sewer trap, and relates to a power strip for installing a sewer trap, which is easy to install and has improved binding force of the drain trap.

In general, toilets, sinks, and bathrooms, where water is used, form sewers to let domestic sewage flow. As it is contaminated with many inorganic and organic substances, it decomposes and emits an odor, and the odor of the sewer is introduced into the room along the drain pipe connected to the sewer, so the room is polluted with the odor.

Moreover, since the toilet is mainly installed inside the bathroom at home, the odor leaking through the sealing portion of the toilet is introduced into the home as it is, causing another problem of contaminating the room.

In order to solve this problem, various types of sewer traps have been developed, commercialized, and released on the market, and an example of this is a sewer odor prevention device disclosed in Korean Patent Registration No. 10-1113539.

In the conventional sewer trap, the rotational cover maintains a state in which the incision is closed by a return means, which is usually a torsion spring, and when the sewage drained to the sewer exceeds a certain amount, the rotational cover rotates downward to open the incision and drain the water. is using

In addition, research and development of multi-tap for drain trap installation are actively progressing in order to efficiently prevent odor with a plurality of drain pipes using a small number of drain traps.

Accordingly, the sealing unit 117 may be provided with stronger fixing force.

The sealing part 117 may be provided to be inserted into the accommodating part 135 by about 5% to 15% of the cross-sectional area. This is to ensure that the sealing part 117 can receive a predetermined or more bonding force from the accommodating part 135 and to facilitate positioning the sealing part 117 inside the accommodating part 135 .

Drain coupling shield 7 may be provided with an elastic material to facilitate separation and coupling. In addition, the drain coupling shield 7 may have a different shape depending on the diameter of the drain coupling portion 113 .

For example, when the diameter of the drain coupling portion 113 is relatively small, the drainage coupling shield 7 may be provided in a shape surrounding the outer circumferential surface of the drainage coupling portion 113 in a circular plate.

In addition, when the diameter of the drainage coupling portion 113 is relatively large, the drain coupling shield 7 surrounds both the outer and inner circumferential surfaces of the drainage coupling portion 113, and the center is the inner side of the drainage coupling portion 113. It may be provided in a recessed shape.

Furthermore, the drain coupling shield 7 may be provided with a plurality of protrusions (not shown) on the inner circumferential surface. Accordingly, the drainage coupling shield 7 can be maximally prevented from sliding away from the drain coupling portion 113 due to the plurality of protrusions.

Although representative embodiments of the present invention have been described in detail above, those skilled in the art will understand that various modifications are possible to the above-described embodiments without departing from the scope of the present invention. . Therefore, the scope of the present invention should not be limited to the described embodiments and should not be defined, and should be defined by not only the claims to be described later, but also those equivalent to these claims.
