[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a drainage connector used for connecting an eaves basket and a basket and draining rainwater from the eaves to the basket.
[0002]
[Prior art]
FIG. 5 is a use state diagram showing a conventional drainage connector.
[0003]
In the drainage connector 100, a screw part 121 is formed on the outer periphery of a cylindrical part 111 that is inserted into a drop opening N <b> 1 formed in the eaves bowl N, and a hook piece part 131 is formed on the upper end of the cylindrical part 111. A screw groove 112 to be screwed into the screw portion 121 of the cylindrical portion 111 is formed on the upper end side of the lid 101, and the upper end portion of the lid 101 sandwiches the periphery of the drop opening N1 to hold the flange piece portion. Covers the cylindrical main body 102 in which a flange 122 superposed on 131 is formed and a lower connecting portion 132 inserted in the flange T or the like is formed on the lower end side, and the opening 141 of the lid 101. And a dustproof net 103 installed.
[0004]
In the drainage connector 100 having such a structure, the cylindrical portion 111 of the lid body 101 is inserted into the drop opening N1 of the eaves N, and the screw groove 112 of the cylindrical main body 102 is inserted into the screw portion 121 of the cylindrical portion 111. When screwed, the collar piece 131 and the collar 122 are pressure-bonded with the peripheral edge of the drop opening N1 being clamped, and the cylindrical main body 102 and the lid 101 are connected.
[0005]
Then, if the eaves T or the like is extrapolated to the lower connecting portion 132 of the cylindrical main body 102, the eaves N and the eaves T are connected, and rainwater from the eaves N can be drained to the eaves T or the like. it can.
[0006]
[Problems to be solved by the invention]
However, in order to connect the drainage connector 100, the threaded structure is such that the screw part 121 of the cylindrical part 111 is fastened to the screw groove 112 of the cylindrical main body 102.
[0007]
Therefore, in order to connect the cylindrical main body 102 and the lid 101, it takes time and effort to turn and tighten the cylindrical portion 111, and there is a problem that the connecting operation is troublesome.
[0008]
Further, because of the screwed structure, the cylindrical main body 102 provided with the thread groove 112 is limited to a cylindrical shape, and other than the cylindrical collar T or the like is directly connected to the lower connecting portion 132 of the cylindrical main body 102. There was also a problem that could not be connected.

[0047]
As shown in FIG. 2 (a), once this hooked portion 32 is hooked on the hook portion 31 of the lid 1, and the operating portion 33 is pushed downward as indicated by the arrow in the figure, The operating portion 33 is folded by tensioning the hooking portion 31 and the hooked portion 32, and as shown in FIG. 2B, the cylindrical main body 2 and the lid body 1 are pressure-bonded and easily connected. Can do.
[0048]
Moreover, even if the latching | locking part 31 and the to-be-latched part 32 are provided in the cylindrical main body 2 and the cover body 1 reversely, it is the same.
[0049]
As described above, according to the present invention, the cylindrical main body 2 and / or the lid body 1 is provided with the fixing tool 3 to which both are crimped and connected. The lid 1 and the cylindrical main body 2 can be easily connected by pressure bonding.
[0050]
FIG. 3 is a use state diagram showing another reference example of the fixing device according to the present invention, and FIG. 4 is a longitudinal sectional view schematically showing a main part of FIG.
[0051]
Incidentally, FIG. 1, denoted by the No. identical marks at a site common to FIG. 2, their description is omitted.
[0052]
The fixing tool 3 includes a main body arm portion 52 provided on the inner surface of the cylindrical main body 2 and provided with a screw hole 51, and a hole portion 53 provided on the inner surface of the lid body 1 and superimposed on the screw hole 51. The cover arm portion 54 is provided, and a screw hole 51 and a fastener 55 such as a screw penetrating the hole portion 53.
[0053]

The tubular body 2 and the lid body 1 are connected by being crimped by 55.
[0054]
Here, the fastening by the fastener 55 is not the above-described screwed structure.
[0055]
The screw hole 51 includes a hole in which a screw groove is formed, a tap hole, and the like, but in short, a structure in which the fastener 55 is screwed is sufficient.
[0056]
Moreover, although the hole part 53 of the example illustrates the through-hole through which the fastener 55 passes, the hole part 53 is not limited to this, and a hole or a tap hole in which the screw groove is formed. You may form in etc.
[0057]
The fastener 55 is meant to include a bolt and a nut in addition to a tapping screw having a cutting function.
[0058]
According to the drainage connector A provided with the fixing tool 3 having such a structure, when the fastener 55 is tightened and the main body arm portion 52 and the lid arm portion 54 are crimped, the cylindrical main body 2 and the lid body 1 Can be easily connected by pressure bonding.
[0059]
Further, as shown in FIGS. 3 and 4, the main body arm portion 52 and the lid arm portion 54 can be installed in a crossed state.
[0060]
Thus, if the main body arm portion 52 and the lid arm portion 54 are installed in a crossed state, when the cylindrical main body 2 and the lid body 1 are connected by pressure bonding, the main body arm portion 52 and the lid arm arm are connected. a Department 54 can function as except garbage in the waste water.
[0061]
In addition, although the fixing tool 3 shown by the present Example illustrated the case where operation and a fastening operation | work were performed from the upper part of the cover body 1 of all, of course, it is also possible to work this from the downward direction of the cylindrical main body 2. Depending on the installation location of the drainage connector A, the fixing tool 3 can be operated from above or below.
[0062]
In addition, one or more fixing tools 3 are sufficient.
[0063]
