There is a problem in that it is difficult to adjust the position of the device 8 after it is placed on the floor 202.

[0008]

The connecting structure between the toilet drain port and the drain socket according to the present invention has been devised to solve such a problem. According to the first aspect of the present invention, a socket packing is attached to a cylindrical connection port at an upper end of a drain socket fixed to a floor surface in a state of being connected to a drain pipe buried in the floor to form a toilet bowl. Toilet bowl having a downwardly projecting drain port inserted into the insertion port at the center of the socket packing in an elastic contact state, so that the drain port and the drain socket are connected in a watertight manner via the socket packing. In the connection structure between the drain port and the drain socket, an elastic cylindrical packing is fitted around the outer peripheral surface of the drain port of the toilet, and the outer peripheral surface of the cylindrical packing is elastically attached to the inner peripheral surface of the insertion port portion of the socket packing. It is characterized in that it is fitted in a watertight manner in a contact state.

According to a second aspect of the present invention, in the first aspect, the insertion opening of the socket packing is formed in a cylindrical shape having an inner diameter corresponding to an outer diameter of the cylindrical packing mounted on the drain port. Features.

According to a third aspect of the present invention, in the first or second aspect, the socket packing is provided with an insertion guide portion having a tapered shape increasing in diameter upward following the upper end of the insertion opening. It is characterized by the following.

According to a fourth aspect of the present invention, in the socket packing according to any one of the first to third aspects, the socket packing is provided between the insertion opening and the outer peripheral portion by elastic deformation in a radial direction of the insertion opening. It is characterized in that a deformation absorbing portion for absorbing deformation is provided.

According to a fifth aspect, in the fourth aspect, the deformation absorbing portion has a bellows shape.

According to a sixth aspect of the present invention, in any one of the first to fifth aspects, at least one of the cylindrical packing and the socket packing has self-lubricating performance.

[0014]

In the above conventional connection structure,
The drain port 210 of the toilet bowl is inserted into the insertion port part by pushing the insertion port part 216 of the socket packing firmly because the outer peripheral surface of the ceramic drain port 210 has many fine irregularities. This is because the minute unevenness is absorbed by the socket packing so as to prevent the generation of a gap, but this makes it difficult to adjust the position of the toilet 208 as described above.

Here, in the connection structure according to the first aspect, an elastic cylindrical packing is externally fitted on the outer peripheral surface of the drain port of the toilet, and the outer peripheral surface of the cylindrical packing is connected to the inner peripheral surface of the insertion port portion of the socket packing. According to the connection structure of the first aspect, the outer peripheral surface of the cylindrical packing is made to be a smoother surface with respect to the outer peripheral surface of the drain port of the toilet. Therefore, when the drain port is inserted into the insertion port of the socket packing via such a cylindrical packing, the water port between them does not need to be pushed so strongly as in the conventional connection structure. Nature can be secured.

Therefore, according to the connection structure of the first aspect,
When the drain port of the toilet is inserted into the socket packing, the operation can be facilitated. Furthermore, according to this connection structure, the watertightness between the drain port and the socket packing can be enhanced through the cylindrical packing.

According to a second aspect of the present invention, the insertion opening of the socket packing is formed in a cylindrical shape having an inner diameter corresponding to the outer diameter of the cylindrical packing. In this case, the cylindrical packing and the socket packing are formed. In this case, the contact area with the insertion opening can be increased, and the sealing performance can be further improved.

According to a third aspect of the present invention, there is provided a tapered insertion guide portion having an upwardly increasing diameter following the upper end of the insertion opening of the socket packing. When the cylindrical packing is attached to the drain port and inserted into the insertion opening of the socket packing, the insertability can be improved, and the insertion operation can be facilitated. In this case, a tapered insertion guide surface in a direction corresponding to the lower end portion can be provided on the side of the cylindrical packing.

According to a fourth aspect of the present invention, the socket packing is provided with a deformation absorbing portion for absorbing radial deformation of the insertion opening by elastic deformation. Due to the elastic deformation of the deformation absorbing portion, the radial deformation of the insertion port can be easily absorbed, and therefore, the state where the toilet is placed on the floor, that is, the toilet drain port is inserted into the insertion port of the socket packing. It becomes possible to easily adjust the position of the toilet under the condition.

In this case, the deformation absorbing portion can be formed in a bellows shape. With this configuration, the deformation absorbing portion can be elastically deformed more easily, and therefore, the insertion opening portion of the socket packing can be easily deformed in the radial direction with a small force. That is, it is possible to more easily adjust the position of the toilet along the floor surface.

In the present invention, at least one of the cylindrical packing and the socket packing can have self-lubricating performance. Here, the self-lubricating performance means a material that holds a liquid lubricant on the surface and inside, and exerts the lubricating performance by the action of the liquid lubricant.

According to this configuration, it is possible to smoothly insert the cylindrical packing attached to the toilet drain into the insertion opening of the socket packing. That is, it is possible to insert the cylindrical packing into the insertion opening while satisfactorily sliding the cylindrical packing and the insertion opening of the socket packing without causing a large frictional force between them.

In particular, when the socket packing is provided with a deformation absorbing portion such as the bellows-shaped portion, by providing the tubular packing or the socket packing with self-lubricating performance, the insertion opening of the socket packing is provided. When a tubular packing is inserted into a part under a condition attached to the toilet drain, the socket packing is elastically deformed in the deformation absorbing part based on the frictional resistance between them, and the insertion work cannot be performed well. Such inconveniences can be avoided.
