Abstract

PURPOSE: A built-in type sprinkler head is provided to maintain a compressed form of a fuse box and a triangular plate by being operated by spraying a fire extinguishing solution. CONSTITUTION: A built-in type sprinkler head comprises a frame, a body(230), and a fuse box(240). The frame is combined with a tailrace connected to a pipe for a fire-extinguishing solution. In the body, a hanging sill combined with the end of frame is formed. The fuse box is composed of a fusible material, bead and a thermal conductor(248). The fuse box is formed by being successively laminated. The fuse box pushes the support plate to outside in order to expand the support plate. In the fuse box, the lower part of support plate is combined with the lower part of the body.

Description

 Buried sprinkler head {built-in type sprinkler head}

The present invention relates to a buried sprinkler head, when the melted material melts due to room temperature conditions, the bead leaves the fuse box by the restoring force of the c-type spring, and at the same time, the triangular support is introduced into the fuse box and the support body. This function works by releasing the locking jaw of the stopper and spraying the extinguishing water by lowering the deflector to keep the fuse box and the triangular support compressed. It is directed to an embedded buried sprinkler head.

In general, sprinkler is mandatory in high-rise buildings or factory buildings of a certain size or more in order to extinguish the fire at the time of an unexpected fire. The installation of the fire sprinkler for fire extinguishing has been used in various ways depending on the installation method and the purpose of use of the sprinkler head, but the height of the ceiling according to the shape of the sprinkler head and a malfunction thereof have always been accompanied by problems.

The conventional sprinkler head is formed of two pillars (frame) on the left and right sides of the waterproof passage, and fixedly attaches a water jet plate to the bottom of the pillar grounding point, and assembles the waterproof passage blocking plate and the glass bulb between the two pillars. Is completed.

This type of sprinkler head has a problem that can be easily broken from the impact even after the handling process or installation because there is no protection of the thermal element assembled in the center of both pillars.

In particular, the conventional built-in sprinkler head is installed by attaching an impact prevention plate with lead to the bottom of the head body connected to the pipe in order to prevent protruding from the ceiling material. This structure has a double structure in which the impact prevention plate is separated and separated from the left and right shocks and the up and down impacts, and the fuse installed inside the head body is separated and operated in the second place.

 An object of the present invention is to provide a buried sprinkler head so that the sprinkler head is not protruded more than the ceiling material in order to solve the problems of the prior art.

In addition, the present invention is to provide a buried sprinkler head that is exposed to the heat collecting plate is in close contact with the molten material can react quickly and accurately to the external temperature conditions in the event of a fire.

An object of the present invention, the sealing membrane is coupled to the waterproof passage connected to the pipe; A deflector coupled to the closed membrane end; Trivet shaped supports; A fuse box formed of a molten material, a bead, and a thermal conductor is sequentially stacked, and the fuse box pushes the c-type spring outward to expand the support outward, and the support bottom is coupled to the locking jaw of the lower part of the body. Being a sprinkler head; Including a deflector built in the body, blocking the discharge port of the frame, the deflector is coupled to the sealing film supported by the fuse box, when the molten material of the fuse box is melted by external heat, by the restoring force of the c-type spring The triangular support is pushed inwards and the beads are released and at the same time the support is moved inwards to release the locking jaw of the lower body, the fuse box is achieved by the buried sprinkler head is disengaged.

 This buried sprinkler head reduces the size of the sprinkler head by the compression coupling of the triangular support and the fuse box, so that the sprinkler head does not protrude from the ceiling material, which makes the interior of the building beautiful and there is no protruding part. By using the restoring force of beads and C-type springs, the shape was simplified and thus the production efficiency was increased, and at the same time, it was able to respond quickly and accurately to external temperature conditions in case of fire.

Figure 8 is an exploded perspective view of the fuse box of the built-in sprinkler head according to an embodiment of the present invention.

The sprinkler head of the present invention is a fuse box made of a molten material, a bead and a heat conductor is a principle that the beads are aligned in a straight line by holding the beads in the molten material and the heat conductor to keep the support inflated outward.

In addition, when heat is applied to the heat collecting plate, the molten material in close contact with the heat collecting plate is melted and fixed, and the bead and the heat conductor are separated by the restoring force of the C-type spring, and the support moves to the inside, so that the fuse box and the support are caught in the lower part of the inner body. Depart from.

When the fuse box and the support are separated, the extinguished water, which is sealed by the lowering of the deflector by water pressure, is injected.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. Prior to this, terms or words used in the present specification and claims should not be construed as being limited to the common or dictionary meanings, and the inventors should properly explain the concept of terms in order to best explain their own invention. Based on the principle that it can be defined, it should be interpreted as meaning and concept corresponding to the technical part of the present invention.

Therefore, the embodiments described in the specification and the drawings shown in the drawings are only the most preferred embodiment of the present invention and do not represent all of the technical parts of the present invention, various modifications that can be replaced at the time of the present application It should be understood that there may be equivalents and variations.
