, 13, and an inward convex portion 16 protruding from the lower inner circumferential edge of the frame 24 to enable the clamping bodies 12, 13 to be attached and held on the lower side of the stopper 3, and by thermal melting or thermal softening, The clamping force on both the clamping bodies 12 and 13 and the locking body 11 by the clamping bodies 12 and 13
and a heat-fusible fusible body 22 provided in order to be able to reduce the clamping force of the clamping bodies 11, and the locking bodies 11 are provided with heat-fusible fusible bodies 22 provided to reduce the clamping force of the clamping bodies 12 and 13. In a sprinkler head configured to be expandable and retractable so that the clamping bodies 12 and 13 can be detached from the frame 24 by contracting to release the engagement with the plug body 3, a female thread is provided on the inner circumferential surface of the plug body 3. 6 is formed, and a threaded body 19 that can come into contact with the upper surface of the clamping body 12 is screwed into the female threaded part 6 with a gap 3a formed in the plug body 3. A sprinkler head characterized by: 5. A stopper 3 for abutting against the lower surface of the peripheral edge 1c of the outlet 4 of the sprinkler head body 1 to close the outlet 4 and a ring-shaped or partially cut-out ring-shaped locking body 11 are attached to the flange. A pair of upper and lower clamping bodies 12 that can be clamped with parts exposed from 12d and 13b.
, 13, and an inward convex portion 16 protruding from the lower inner circumferential edge of the frame 24 to enable the clamping bodies 12, 13 to be attached and held on the lower side of the stopper 3, and by thermal melting or thermal softening, The clamping force on both the clamping bodies 12 and 13 and the locking body 11 by the clamping bodies 12 and 13
and a heat-fusible fusible body 22 provided to reduce the clamping force of the locking body 1.
1 is configured to be expandable and contractible so that the clamping bodies 12 and 13 can be detached from the frame 24 by contracting to release the engagement with the inward convex portion 16 due to a decrease in the clamping force of the clamping bodies 12 and 13. In this sprinkler head, a notch 17 is provided on the inner circumferential surface of the inward convex portion 16 in which the locking body 11 can be fitted and locked, and the clamping bodies 12 and 13 fall off and the plug is removed. In order to guide the downward movement of the plug body 3 when the body 3 falls from the sprinkler head body 1,
A guide ring 9 having a slidable guide portion 10 is fitted onto the sprinkler head main body 1 on its outer peripheral surface, and the guide ring 9 is provided on the plug body 3 via a deflector 8. Outlet 4 of the sprinkler head body 1
A sprinkler head characterized in that an elastic body 7 is interposed between the bottom surface of the peripheral edge 1c and the stopper 3 in a press-contact state.
