Description

Technical Field

[0001] This utility model relates to the field of fire sprinkler head technology, specifically to an installation structure for a fire sprinkler head. Background Technology

[0002] Fire sprinklers are nozzles that automatically activate within a predetermined temperature range under heat, or are activated by control equipment according to a fire signal, and spray water to extinguish fires according to the designed spray pattern and flow rate. Glass bulb sprinklers are a common type of fire sprinkler, whose heat-sensitive element is a glass bulb. When the nozzle is heated, the working fluid inside the glass bulb reacts, causing the bulb to burst and open.

[0003] A search revealed a patent publication dated October 10, 2023, in China, patent number CN219804183U, describing an installation structure for a fire sprinkler head. The structure includes a pipe joint, a limiting ring fixedly connected to the inner wall of the pipe joint, a sealing valve engaged with the inner wall of the limiting ring, a threaded rod slidably connected to the limiting sleeve, a sealing block fixedly installed on the outer wall of the top of the threaded rod, a thermosensitive glass body installed on the outer wall of the sealing block away from the threaded rod, and a bearing ring fixedly connected to the outer wall of the bottom of the limiting sleeve. A deflector plate is rotatably connected to the end of the bearing ring away from the limiting sleeve. In this invention, through the cooperation of the deflector plate, bearing ring, limiting sleeve, threaded rod, and sealing block, after a fire, if the thermosensitive glass body shatters and the sealing valve falls off, rotating the deflector plate drives the threaded rod upward, thereby moving the sealing block upward until it inserts into the inner wall of the limiting ring. The sealing block adheres to the inner wall of the limiting ring to achieve a seal, thus enabling timely temporary sealing of the sprinkler head after a fire, saving water resources.

[0004] While the aforementioned existing technical solution facilitates temporary sealing of the sprinkler heads and saves water resources, the device requires two pull plates to be pulled simultaneously during installation and disassembly, necessitating additional personnel to install the equipment. This makes it inconvenient for a single person to install the equipment, reducing work efficiency. Utility Model Content

[0029] The present invention will be further described in detail below with reference to the accompanying drawings.

[0030] Reference Figures 1-6An installation structure for a fire sprinkler head includes a pipe joint 1 and an installation ring 2. A limiting ring 3 is fixedly connected inside the pipe joint 1. A first sealing element 4 is movably provided at the opening of the limiting ring 3. An annular groove 5 that mates with the installation ring 2 is fixedly connected to the bottom end of the pipe joint 1. The top end of the installation ring 2 is inserted into the annular groove 5. Two corresponding 7-shaped grooves 6 are formed on the outer wall of the installation ring 2. A positioning block 7 that mates with the 7-shaped groove 6 is fixedly connected to the inner wall of the annular groove 5. A positioning groove 8 that mates with the positioning block 7 is formed on the inner wall of the 7-shaped groove 6. Four evenly distributed connecting rods 9 are fixedly connected to the bottom end of the installation ring 2. A connecting plate 10 is fixedly connected to the bottom end of the four connecting rods 9. A deflector plate 11 is fixedly connected to the bottom end of the connecting plate 10. A threaded hole is formed on the connecting plate 10. A threaded rod 12 is threadedly connected inside the threaded hole. A second sealing element 13 is rotatably connected to the top end of the threaded rod 12. The thermosensitive glass body 14 is held between the inlet fitting 13 and the first sealing fitting 4. The pipe connector 1 is connected to the outlet position. At this time, the mounting ring 2 is inserted into the annular groove 5, so that the positioning block 7 is inserted from the short groove of the 7-shaped groove 6. Then, the positioning block 7 slides along the long groove of the 7-shaped groove 6. When the position of the positioning block 7 coincides with the positioning groove 8, the mounting ring 2 moves downward under the action of gravity, so that the positioning block 7 is inserted into the positioning groove 8, thereby connecting the mounting ring 2 and the pipe connector 1. At this time, the first sealing fitting 4 can be abutted against the opening of the limiting ring 3. Then, the thermosensitive glass body 14 is placed between the first sealing fitting 4 and the second sealing fitting 13. At this time, the threaded rod 12 can be rotated to drive the second sealing fitting 13 to move, so that the second sealing fitting 13 and the first sealing fitting 4 cooperate to clamp the thermosensitive glass body 14, thereby installing the equipment. This facilitates the installation of the equipment by a single person and improves work efficiency.

[0031] Reference Figures 2-6 A rubber sealing ring 15 is fixedly connected to the bottom end of the limiting ring 3. The bottom end of the rubber sealing ring 15 is in close contact with the first sealing member 4. The rubber sealing ring 15 is used to improve the sealing between the limiting ring 3 and the first sealing member 4, thereby preventing water leakage and improving the stability of the equipment.

[0032] Reference Figures 2-5 The bottom end of the first sealing member 4 and the top end of the second sealing member 13 are provided with anti-slip grooves 16. The two ends of the thermal glass body 14 are respectively inserted into the two anti-slip grooves 16. The two anti-slip grooves 16 cooperate to position the thermal glass body 14 and prevent the thermal glass body 14 from tilting and slipping, thereby improving the stability of the equipment.

[0033] Reference Figure 2 and Figure 3A push ring 17 is slidably connected inside the annular groove 5. Multiple evenly distributed springs 18 are provided between the push ring 17 and the annular groove 5. The bottom end of the push ring 17 is in close contact with the mounting ring 2. When the positioning block 7 is inserted into the positioning groove 8, the springs 18 push the push ring 17 to move, so that the push ring 17 presses the mounting ring 2, reducing the shaking or tilting of the mounting ring 2, thereby improving the stability of the equipment.

[0034] Reference Figure 2 and Figure 3 Two limiting rods 19 are fixedly connected to the top of the connecting plate. Both limiting rods 19 are slidably connected to the second sealing member 13. The limiting rods 19 are used to limit the second sealing member 13 to prevent the second sealing member 13 from deflecting, thereby improving the stability of the equipment.

[0035] In summary, the working principle and process of the fire sprinkler head installation structure are as follows: First, connect the pipe connector 1 to the outlet position. Then, insert the installation ring 2 into the annular groove 5, allowing the positioning block 7 to be inserted from the short groove of the 7-shaped groove 6. The positioning block 7 then slides along the long groove of the 7-shaped groove 6. When the position of the positioning block 7 coincides with the positioning groove 8, the installation ring 2 moves downwards under gravity, causing the positioning block 7 to insert into the positioning groove 8, thus connecting the installation ring 2 to the pipe connector 1. At this point, the first sealing member 4 can be placed against the opening of the limiting ring 3. Then, the heat-sensitive glass body 14 is placed between the first sealing member 4 and the second sealing member 13. The threaded rod 12 can then be rotated to move the second sealing member 13, causing the second sealing member 13 and the first sealing member 4 to cooperate, thus sealing the heat-sensitive glass body 14. The clamping mechanism is used to install the equipment, facilitating single-person installation and improving work efficiency. The rubber sealing ring 15 enhances the seal between the limiting ring 3 and the first sealing member 4, preventing water leakage and improving equipment stability. The two anti-slip grooves 16 work together to position the thermosensitive glass body 14, preventing it from slipping or tilting, thus improving equipment stability. When the positioning block 7 is inserted into the positioning groove 8, the spring 18 pushes the push ring 17 to press the mounting ring 2, reducing shaking or tilting of the mounting ring 2 and improving equipment stability. The limiting rod 19 limits the second sealing member 13, preventing it from tilting and improving equipment stability.

[0036] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
