The first embodiment of the present invention, as shown in FIGS. 1 to 5, corresponds to a female member, a kitchen sink (7) which is a tank having a connection port (2), and a male member. At the upper end, a flange-shaped fixed wall (4) that is in contact with the peripheral edge of the connection port (2) is provided around the drainage trap (1). 6), packing (P), which is an annular watertight member interposed between the kitchen sink (7) and the drain trap (6), and a substantially annular shape, the outer peripheral edge of which is larger than the connection port (2). Spacer (5) whose periphery is larger than the pressure contact wall (1), kitchen sink (7) and drain trap (6)
And a wedge member (3) having a substantially annular shape and having a cutout on one side.

The connecting mechanism is used in such a manner that the fixing wall (4) comes into contact with the periphery of the connecting port (2) via the packing (P) so that the drain trap is connected to the kitchen sink (7) from the connecting port (2) on the upper surface. (6) is inserted and arranged. Next, a spacer (5) for uniformly dispersing the respective stresses from below the drain trap (6) is arranged between the drain trap (6) on the back side of the kitchen sink (7) and the pressure contact wall (1). From this state, the pressure contact wall (1) of the drain trap (6)
The wedge member (3) is driven between the and the spacer (5) while pressing the members against each other. As a result, a force is applied to the periphery of the connection port (2) of the kitchen sink (7) and the pressure contact wall (1) in a direction away from each other, but the fixed wall (4) of the kitchen sink (7) and the drain trap (6) is moved. Since it is in contact, the drain trap (6) does not fall out of the kitchen sink (7). Further, since the drain trap (6) and the kitchen sink (7) are strongly in contact with each other via the packing (P) at the fixed wall (4), the drain trap (6) and the kitchen sink (7) are watertight. Connection is made.
Since there is no screw part as described above, it is not necessary to control the torque and the construction method is simple. Therefore, the installation of the drain trap (6), which was conventionally performed by two persons, must be performed by one person. Can be done. In addition, since there is no screw portion, it is not particularly necessary to make the shape of the drain trap (6) cylindrical, and the drain trap (6) has a substantially elliptical shape in plan view as in the embodiment.
The range of shape selection can be expanded.

Next, a second embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 6 to 8, the second embodiment of the present invention has a substantially annular connection port (2) corresponding to a female member, and furthermore, a drain pipe strongly in contact with a drain pipe (8) described later. A drain trap (6), which is a drain device having a fixed wall (4) having a connection port (2) with a smaller diameter than (8);

Packing (hereinafter referred to as "triangular packing (D)"), a substantially annular spacer (5), and a connection member for connecting the drainage pipe (8) and the drainage trap (6). And a wedge member (3) having a portion.

As a method of using this connection mechanism, as shown in FIGS. 6 and 7, a triangular packing (D) and a spacer (5) are attached to a tip of a drain pipe (8) in order from the end, and a drain trap ( The drain pipe (8) is inserted into the connection port (2) of (6), and the triangular packing (D) arranged in the drain pipe (8) is brought into contact with the fixed wall (4). Further, a wedge member (3) is driven between the connection port (2) and the spacer (5). Then, a force acts in a direction in which the triangle packing (D) and the connection port (2) of the drain trap (6) are separated from each other via the spacer (5), and the triangle packing (D) is strongly pressed against the fixed wall (4). You. At this time, the inclination of the triangle packing (D) converts the pressing force exerted on the fixed wall (4) toward the inside to a force for tightening the drain pipe (8), and the triangle packing (D) and the drain pipe (D). Since the frictional force during step 8) is increased to make it impossible to slide, the drain pipe (8) and the triangular packing (D) function as an integral unit. Thereafter, as in the conventional example described in paragraph 0003, the triangular packing (D) is fixed to the wedge member (3) and the fixed wall (4), and the drain pipe (8) slides with respect to the triangular packing (D). As it becomes impossible, drain pipe (8)
Is fixedly connected to the drain trap (6). As described above, this connection mechanism does not require any tightening work such as screwing, and even in a narrow space such as a cabinet of a kitchen or the like, only by driving the wedge member (3) into a predetermined position, the drain trap (6) and the drain pipe are connected. (8) can be connected,
It can be constructed in a short time.

Although the present invention is as described above, the present invention is not limited to the above embodiment, and various changes can be made without departing from the gist of the invention. For example, in addition to the kitchen sink (7) and the drain trap (6) of the first embodiment, and the drain trap (6) and the drain pipe (8) of the second embodiment, a female drain pipe shown in FIGS. (8b) for connection with the male drain pipe (8a) and for connection between the drain plug (8c) of the wash basin functioning as the female drain pipe shown in FIGS. 12 to 15 and the male drain pipe (8a). Can be done.

[0017]

The connection mechanism of the present invention has the following effects. 1. Since the male member and the female member can be connected only by driving the wedge member into a predetermined position, it is not necessary to perform a troublesome operation such as torque management. 2. Since the male member and the female member can be connected only by driving the wedge member into a predetermined position, the connection can be easily performed even in a narrow connection space where the screw cannot be turned, and the connection space is not particularly limited. 3. By connecting the male member and the female member via the spacer, the force from the wedge member can be uniformly applied to the male member or the female member. 4. Since there is no threaded portion, shapes other than the cylindrical shape can be used, and the width of the shapes of the male member and the female member can be increased. 5. Since there is no threaded portion, the male member and the female member do not run idle, and can be mounted by one person. 6. For the reasons 1 and 2 above, the cost can be further reduced as compared with the conventional method due to the effect of increasing workability and reducing the number of workers.
