Mounting structure of coupler for sprinkler
Disclosed herein is a mounting structure of a coupler for a sprinkler. The mounting structure is constructed so that a coupler to which a sprinkler head and a water supply line are connected is fitted into a clamp in a lateral direction and is secured at a predetermined position by a snap part, and a support structure having a shape corresponding to the cross-section of the coupler is provided so as to prevent the coupler from rotating in the clamp.
1. A mounting structure of a coupler for a sprinkler, comprising:
a coupler having flat surfaces, extrapolated lines of the flat surfaces forming a polygon;
a clamp, comprising:
a first cavity provided in a first end of the clamp in such a way as to be open to the top;
an opening provided in a second end of the clamp;
a second cavity provided in each of sidewalls of the clamp which are adjacent to the opening in such a way as to be open to the top;
a through hole provided at a position on each of the sidewalls so that a stock bar is fitted into the through hole; and
a hinge part protruding outwards from the second cavity;
a support plate provided integrally on each of upper and lower ends of the sidewalls, and having a fitting hole which is open towards the opening and is formed to correspond to the flat surfaces; and
a rotary part rotatably connected at an end thereof to the hinge part, and opening or closing the opening; and
a snap part, comprising:
a holding part rotatably connected at both ends thereof to the sidewalls of the clamp, so that a position of the holding part is limited by the first cavity; and
a compressing part formed by bending an end of the holding part, and pushing the stock bar towards the opening.
2. The mounting structure as set forth in claim 1 , wherein the rotary part is a rectangular pipe.
3. The mounting structure as set forth in claim 1 , wherein the through hole communicates with the fitting hole.
4. The mounting structure as set forth in claim 1 , wherein a wing is provided on an upper edge of the through hole, a screw being fastened to the wing.
