Concealed fire sprinkler for easy assembly

technical field

The convenient assembly concealed fire sprinkler provided by the utility model is a novel concealed sprinkler which can simplify the number of components and is easy to install, and is designed for the inconvenience encountered in the assembly of the hidden fire sprinkler. .

Background technique

Sprinklers for firefighting are usually installed on the ceiling-mounted fire-fighting water supply pipelines in the building. When a fire occurs accidentally in the room, the automatic temperature-sensing design of the temperature-sensitive glass ball is set in the sprinkler. Spray fire water from the valve to extinguish the flames.

At present, the sprinklers for fire protection with automatic temperature sensing performance seen by the people can be divided into two types: concealed and non-concealed sprinklers. The difference between them is only whether there is a decorative cover on the periphery and bottom of the sprinkler body 1. 2 and the shutter plate 3 (as shown in Figure 1). Among them, the hidden sprinkler head is better, because the hidden sprinkler head can cover the dirt on the indoor ceiling through the decorative cover 2 and the cover plate 3, so as to protect the water gate 11 and the temperature-sensitive glass bulb loaded in the body. 12, and improve the action flexibility of components such as the backwater plate 13 (cooperating shown in Figure 3), so among the people, the installation and use of hidden sprinkler heads are more popular.

There are two temperature-sensing devices in the concealed fire sprinkler, such as taking the common hidden sprinkler as an example (as shown in Figure 3), wherein the first temperature-sensing device is set on the pin 33 at the bottom of the nest 31 , and then use the low-temperature tin 34 to solder the pin 33 to the cover plate 3, and use the low-temperature tin 34 to automatically melt when the room temperature in the fire zone reaches 57°C±3°C%, so that the cover plate 3 will automatically fall off, and This releases the water return plate 13 on the body 1, and when the room temperature in the fire zone continues to rise to 68°C (95%-115%), the temperature-sensitive glass bulb 12 of the second temperature-sensing device on the body 1 will automatically break , to release the sluice 11 in the body 1, allowing the water flow in the fire fighting water pipe 9 to vent out, and through the backwater plate 13 bifurcations, the diffused water flow becomes the spraying effect of water splashes, so as to reach the purpose of extinguishing a large range of indoor flames.

The hidden fire sprinkler currently used by the people is not convenient to install, because the conventional hidden fire sprinkler mainly consists of a sprinkler body 1 equipped with components such as a water gate 11, a temperature-sensitive glass ball 12, and a water return plate 13. 1, a base 31 with a shutter 3 at the bottom, and another decoration cover 2 and many other unit components (as shown in Figure 1), when installing and using (as shown in Figure 2), the decoration cover 2 must first It is locked on the tooth tube part 10 of the main body 1, and then a screw pliers 14 must be used to buckle the ribs 15 on the main body 1 that are parallel on both sides, and in the narrow space of the decorative cover 2, apply force to rotate the screw. pliers 14, so that the tooth pipe part 10 of the body 1 can be engaged with the inner tooth part 91 in the ceiling-type fire-fighting water pipe 9, so that the body 1 can be suspended and locked on the fire-fighting water pipe 9, and then the tooth on the decorative cover 2 The surface 21 is used as a guide rail, and the socket 31 of the protruding teeth 32 is locked, so that the bottom is welded with the socket 31 of the cover plate 3, and the body 1 of the sprinkler head, the water gate 11 and the temperature-sensitive glass mounted on the body can be covered and sealed. Ball 12 and water return plate 13 and other components, for the installer, its assembly process is really too difficult. There are too many assembly components around the body 1, which is the key to the disadvantages of labor-intensive and time-consuming assembly.

Contents of the invention

The purpose of this utility model is to improve and design a kind of convenient assembly concealed fire sprinkler head that can be assembled without using screw pliers hand tools, aiming at the above shortcomings.

The utility model is realized in the following manner:

The technical solution of the utility model is to simplify the three components of the conventional sprinkler body, the shroud, the insert and the decorative cover, and make a combination of the shroud and the decorative cover, and the combined body can be easily rotated. The locking position is located on the periphery of the sprinkler body, making it a shield unit that hides and protects the internal components of the sprinkler body; in addition, the sprinkler body has a toothed part, which can lock the body on the ceiling-type fire hose. Teeth are extended on the rib arms on both sides of the shield unit, and the decorative cover with the circumferential tooth surface in the shield unit is locked on the teeth.

The positive effect of the utility model is: when the simple locking shield is implemented on the sprinkler body, there is no need to use screw pliers, so the number of hand tools carried by the assembler can be greatly reduced, and the fall of the assembler on the indoor ceiling can be greatly reduced. The power consumption of the hanging lock for installing the sprinkler head is extremely convenient and practical for assembly.
