Description

  The present invention relates to a drainage device for a tank body used for drainage equipment having a cabinet section such as a wash basin or a sink, and more particularly to a drainage device for a tank body having a trap function.

  Conventionally, living equipment that has a tank part such as a wash basin and a sink and generates drainage by use (hereinafter these equipment is called “drainage equipment”), drainage generated in the tank from the piping under the floor. To drain to the sewage side, connect a drain to the bottom of the tank. These drainers are equipped with a drainage reservoir inside the drainage that simply allows the drainage to pass through, so that odors and pests do not flow back from the sewage side. There are various types such as a drainage device called a drainage trap constructed, but it is usually necessary to connect the drainage device to the tank body regardless of which structure is adopted.

  FIG. 18 shows an example of a well-known drainage device, and the details thereof will be described. The drainage port having a bottomed cylindrical shape and having an opening provided above, and the upper end of the drainage device main body are shown in detail. A drainage body comprising a flange portion which is a protruding portion provided continuously along the circumference at the periphery, a male screw portion provided along the circumference below the flange portion, and a discharge port provided at the lower end of the side surface; The nut member is provided with a female screw portion that is ring-shaped and screwed with the male screw portion on the inner surface thereof, and has an abutting surface that presses the lower surface of the flange member via the peripheral edge of the attachment hole.

When attaching the above drainage device to the tank body, first, the drainage device main body is brought into contact with the attachment hole provided on the bottom surface of the tank body such as a sink, and the lower surface of the flange portion is brought into contact with the periphery of the attachment hole via packing or the like. Arrange as follows.
Next, the upper surface of the nut member is brought into contact with the peripheral edge of the mounting hole, and then the nut member is rotated, and the male screw portion of the drainage device main body and the female screw portion of the nut member are screwed together, Since the periphery of the attachment hole is strongly sandwiched and fixed with the upper surface of the nut member via the packing, the drainage is attached to the attachment hole of the tank body in a watertight manner. Thereafter, drainage pipes such as S-shaped trap pipes and bellows pipes communicating with the sewage side are connected to the discharge port, and piping to the drainage equipment is completed.

Japanese Patent Laying-Open No. 2003-301491 (FIGS. 14 and 15)

As described in paragraph 0004 above, the drainage device tank and drainage are mostly connected at the factory where the drainage device is manufactured, but the drainage body is large and heavy. If it fits in the attachment hole, the line of sight is blocked, and the state of the back surface of the tank body cannot be seen from the front side of the tank body. For this reason, when performing the screwing operation of the drainage machine body and the lock nut member,
1. 1. When connecting, it is difficult to align the large and heavy drainage body when adjusting so that the male screw part and the female screw part are engaged with each other. When adjusting so that the male screw part and female screw part are meshed at the time of connection, the state of the lock nut member is not visible from the surface side of the tank body. There is. When working from the back side, the state of the lock nut member can be visually recognized, but conversely, the flange portion is a fixed position of the tank body (the stepped portion for housing the flange section provided at the periphery of the mounting hole of the tank body) ) Is not correct because it cannot be confirmed, and it is not possible to directly confirm whether the screw is correctly meshed.

In rare cases, the drainage device is installed on the drainage device after the drainage device is installed at the construction site. For example, when the drain of the drain is on the lower surface of the drain and the drain pipe connecting the drain of the drain and the underfloor piping is a straight pipe made of hard material, the drain is temporarily drained. This is because the drain pipe cannot be piped unless it is removed from. In connection between the attachment hole of the drainage device and the drainage device, there is a problem that water leakage occurs if the tightening strength (hereinafter referred to as “tightening torque”) of the male screw portion and the female screw portion is weak. When connecting in factories, etc., because the equipment is extensive, a work called torque management is performed to numerically manage the tightening torque using a highly calibrated jig. However, unlike a factory that always has jigs, it is time-consuming to prepare such jigs at the construction site. In many cases, there was no problem if water was collected in the tank body and there was no water leakage. Since this torque management was not thorough, there was a strong tendency for quality management to be neglected.
The present invention was invented to solve the above problems, and in a drainage device for a tank body, the drainage device can be easily connected to the tank body, and the drainage device can be connected to the tank body at the construction site.
