Description

A side pressure opening type drain cover

technical field

The utility model relates to the technical field of a drainer cover, in particular to a side pressure opening type drainer cover.

Background technique

The drain cover is a cover for sealing water installed at the mouth of the drain. When it is necessary to store water in the sink, install the cover to the mouth of the drain, and the sealing structure of the sealing rubber ring of the cover is closely attached to the inner cylindrical surface of the mouth of the drain to realize water sealing; when it is not necessary to store water in the sink When the water is stored, the cover is removed, and the water is discharged from the inner hole of the drainer. The composition of the cover of the drain must have a cover and a sealing rubber ring. Simultaneously, because the cover of the water tank is subjected to the effect of water pressure after storing water, the covers of the drains seen in the market are all assembled on the cover body or have handles to take the cover. The cover equipped with a handle has a complex product structure and high cost; the cover with a handle has a complicated manufacturing process and high cost.

Contents of the invention

Aiming at the above-mentioned problems of the cover of the drainer on the market at present, the utility model breaks through the inertial thinking, does not attach a handle structure to the cover body, simplifies the product composition, simplifies the product manufacturing process, and greatly reduces the product cost.

The technical scheme that the utility model adopts is:

The utility model discloses a lateral pressure-opening type drain cover, which is composed of a cover body and a sealing rubber ring. The upper surface of the cover body is a plane, and the middle circumference of the cover body is provided with a sealing groove, and a sealing rubber ring is installed in the sealing groove; the outer cylindrical surface of the sealing groove of the cover body and the inner cylindrical surface of the sealing rubber ring Closely attached, its upper plane is attached to the upper surface of the sealing rubber ring, and its lower plane is attached to the lower surface of the sealing rubber ring; the sealing rubber ring is specially designed, and its cross-section is in the shape of a C-shaped ring. The outer diameter of the upper edge of the sealing rubber ring is larger, and the outer diameter of the lower edge of the sealing rubber ring is smaller; there are several raised structures on the circular plane of the lower side of the upper edge (lower side during work), and these raised structures are distributed In the range of about 180 degrees of the circular plane. Install the cover to the mouth of the drainer to allow the sink to store water; when opening the cover to drain water, press the upper surface edge of the sealing rubber ring of the cover without the raised structure, and then seal the cover with the sealing rubber ring The two raised structures near the non-raised structure area are fulcrum tilted, the seal is opened to drain water, and the cover is also easy to take after the water pressure is removed.

The sealing rubber ring is molded and manufactured in large quantities at low cost. Therefore, the utility model has incomparable advantages in simplifying the product structure and reducing the product cost. Simultaneously, the structure of the utility model also has the advantage of simplicity and beauty, and adapts to the current trend.

Description of drawings

Below in conjunction with accompanying drawing, the utility model is further described:

Figure 1 is a schematic diagram of the assembly structure of the cover and the drain;

Fig. 2 is a schematic diagram of the explosion structure of the cover and the drainer;

Fig. 3 is a schematic diagram of A-A section structure in Fig. 2;

In the accompanying drawings: 10, the cover body; 100, the sealing groove; 20, the sealing rubber ring; 21, the upper edge of the sealing rubber ring; 211, the lower side of the upper edge; 22, the lower edge of the sealing rubber ring; 221, the outer cylindrical surface of the lower edge ; 23, raised structure; 30, drainer.

detailed description

Referring to Fig. 1 to Fig. 3 , a cover for a side pressure-opening type sewer includes a cover body 10 and a sealing rubber ring 20. Sealing groove 100, the sealing rubber ring 20 is embedded in the sealing groove 100; the sealing rubber ring 20 is a ring shape with a C-shaped structure in section, the outer diameter of the upper edge 21 of the sealing rubber ring is relatively large, and the lower sealing rubber ring The outer diameter of the edge 22 is small; several raised structures 23 are arranged on the lower side 211 (lower side during operation) of the upper edge, and these raised structures 23 are evenly distributed in the range of about 180 degrees of the circular plane.

The sealing rubber ring 20 is embedded in the sealing groove 100 of the cover body 10; after the cover body 10 and the sealing rubber ring 20 are combined, they are put into the mouth of the drainer 30, and due to the position-limiting effect of the raised structure 23, the upper edge and the lower side 211 There is a certain gap with the upper surface of the drainer 30, and the outer cylindrical surface 221 of its lower edge is closely attached to the inner cylindrical surface of the mouth of the drainer 30 to realize sealing, and the water tank stores water; The edge of the upper surface of the sealing rubber ring 20 without the protruding structure 23 side, the cover lifts up with the two protruding structures 23 near the area without the protruding structure 23 on the sealing rubber ring 20 as the fulcrum, the seal is opened and the water is drained , and after removing the water pressure, the cover is also easy to take.

The above description is only a preferred embodiment of the utility model. According to the idea of the utility model, there may be changes in the specific implementation and application scope. The content of this specification should not be construed as a limitation of the utility model.
