Two positions up and down in portion 44 are played, tapped through hole 45 and screwed hole 42 turn into coaxial.Then, using two screws 46, on screw-in
The tapped through hole 45 and screwed hole 42 at lower two positions, so as to which horizontal tube 10 and junction block 20 interfix.In addition, by removing
Screw 46, horizontal tube 10 and junction block 20 can be easily separated.
Further, when inner side lug boss 41 is embedded in exterior projection 44, the screwed hole 42 in inner bulge portion 41
Around flat part 42a be embedded in exterior projection 44 recess (not shown) flat part, so as to horizontal tube 10 and joint
Pipe 20 is prevented from rotating against around axis L1.That is, in the fourth embodiment, the flat part 42a in inner bulge portion 41 and outside
The flat part of the recess of lug boss 44 constitutes " rotation constrained mechanism ".It is somebody's turn to do effect and first embodiment party of " rotation constrained mechanism "
Formula is identical.In addition, in this embodiment, be fixed using two screws 46 at upper and lower two position, but same with this enter
The position of row screw fastening can also be a position, or more than three positions.
As described above, the mechanical snap fastener 1,2,3,4 of each embodiment is configured to fix horizontal tube 10 and connect
Head tube 20, and the structure of horizontal tube 10 and junction block 20 can be loaded and unloaded.Thus, for example, as shown in FIG. 11 and 12, can be right
Horizontal tube 10 is changed with other kinds with the mechanical snap fastener of the mechanical snap fastener same configuration of the horizontal tube 10
The junction block of class is simultaneously installed on the horizontal tube 10.
Figure 11 is the figure for the first variation for representing junction block, and Figure 12 is the figure for the second variation for representing junction block.Figure
The construction of the junction block 20 ' of the first variation shown in 11 is by the drain passageway 20c courts of the junction block 20 of first embodiment
To horizontal direction.That is, the axis L1 of the axis L2 ' of the junction block 20 ' and horizontal tube 10 is rectangular and turns into horizontal direction.Separately
Outside, the junction block 20 of the second variation shown in Figure 12 " is the drain passageway 20c and water for the junction block 20 for making first embodiment
The path 10a of flat pipe 10 turns into axis L1 coaxially to be formed.In addition, in the first variation and the second variation, with horizontal tube
The 10 mechanical snap fasteners 1 together constituted with are identical with first embodiment.Thus, it is also possible to species is installed not to horizontal tube 10
Same junction block.
More than, detailed narration is carried out to embodiment of the present utility model referring to the drawings, but specific structure is unlimited
In these embodiments, do not depart from change of the design of the scope of objective of the present utility model etc. and be also included within the utility model
In.
