Description

Sink for Think

1 is a partially disassembled perspective view of the present invention drainage.

2 is a longitudinal cross-sectional view of the assembled state of the in-phase.

The present invention overlaps the outer and inner cylinders formed with the flanges each bent outward at the upper periphery, and forms an annular reservoir for water rods around the drainage pipe installed at the center of the bottom of the outer cylinder. The inner and outer cylinders can be fastened by bolts at the center of the bottom surface, and the bolt mounting pipes are vertically installed at the inner center of the drain pipe so as to be integral with the support pieces, and the lower end of the inner cylinder has an inner center of the drain pipe. The sink is configured to install the deodorant before being able to be covered with a certain interval in the upper part as a support piece, and to fasten and assemble the inner and outer cylinders by attaching the bolt to the screw through a well-known bolt ball installed in the center of the deodorization. It is about dragon drainage.

In the conventional drainage for sinks, female and female threads are generally formed on the inner and outer circumferential walls of the upper end of the outer cylinder and the inner cylinder, and the inner and outer cylinders are subtracted from each other with the sink bottom plate interposed therebetween. In the case of drainage to be formed, a screw is formed on the outer circumferential wall of the upper end of the outer cylinder to be attached to the sink bottom plate using a separate annular fastening nut that can be screwed together.

Therefore, such a conventional drainage for sink has to process the screw in the mold to install the threaded portion on the inner wall of the inner cylinder or the outer cylinder. In case of disassembly or disassembly, it is necessary to use special tools such as wrenches to firmly tighten the inner and outer parts of the cylinder. Therefore, it was not easy to clean, replace or repair the drainage. On the other hand, as a design for eliminating these defects, a drainage hydrant for fastening the outer cylinder and the inner cylinder with a single screw is known as Published Utility Model No. 77-255. There is a flaw that the original deodorizing function could be expected.

The present invention is to solve the above-mentioned conventional defects and to devise a low, and described in detail by the accompanying drawings the structure and effect of the present invention as follows.

Periphery of the drain pipe 4 provided with the outer cylinder body 1 and the inner cylinder body 6 in which the flanges 2 and 7 which were bent outwardly at the upper periphery, respectively, overlapped with each other, and installed in the bottom center of the outer cylinder body 1. In the annular reservoir 5 for sealing, the bolt screwing tube 8 is integrally formed with the drain pipe 4 with several supporting pieces 9 at the inner center of the drain pipe 4 of the outer cylinder 1. It is installed vertically, and in the inner center of the lower end of the inner cylinder (6), the deodorizing war 11 that can be covered with a predetermined interval on the upper portion of the drain pipe (4) is installed integrally with the support piece (12) On the bottom of the well-known bolt ball 10 laid in the center of the deodorization 11, the protrusion 14 to be brought into contact with the above-described bolt screw mounting tube 8 is projected to turn the bolt 14 into the bolt ball 10. It penetrates through and is attached to the mounting tube 8, and the outer cylinder 1 and the inner cylinder 6 are fastened.

In the figure, reference numeral 15 denotes a sink bottom plate and 16 denotes a filter plate as an imaginary line.

The present invention configured as described above has the inner cylinder 6 when the inner cylinder 6 and the outer cylinder 1 are coupled up and down with the sink bottom plate 15 interposed therebetween as shown in the cross section in FIG. ) Before the deodorization (11) is covered on the drain pipe (4) and the bottom of the projection (13) touches the top surface of the mounting tube (8). In this state, the bolt 14 is fitted with the bolt ball 10 to be attached to the screwing tube 8, and the inner and outer cylinders 6 and 1 clamp the sink bottom plate 15 between the flanges 7 and 2. It is firmly assembled in one state.

In addition, the water seal is formed in the annular reservoir 5 by the deodorization 11 which is covered on the drain pipe 4 to prevent the occurrence of odor.

The present invention, as described above, can not only firmly fasten the inner and outer cylinders as one bolt 14, but also before the deodorization (11) is fixed to the inner cylinder (6) by the support piece (12) to the inner cylinder (6) Is assembled into the outer cylinder 1, the deodorization 11 of the inner cylinder 6 is covered with a predetermined interval on the drain pipe 4 of the outer cylinder 1 to form a water seal, and thus deodorization, which is an original function of drainage. The effect is that the structure is simple and simple, there is also an effect that can reduce the production cost.

Claims (1)

The inner pipe 6 is superposed inside the outer cylinder 1 in which the drain pipe 4 is vertically placed in the bottom center to form the annular reservoir 5 for sealing, and the inner and outer cylinders have one bolt 14. In the well-known drainage system which is fastened to the main body, the bolt screwing tube 8 is vertically inserted into the support piece 9 at the inner center of the drain pipe 4, and the drain pipe 4 is located at the inner center of the lower end of the inner cylinder 6. The drainage for sink configured to fix the bolt 14 to the screwing pipe 8 with the well-known bolt hole 10 installed before the deodorization 11 is fixed to the support piece 12 installed on the cover. I'm.
