Abstract
Description
Technical Field
[0001] This utility model relates to the field of fire sprinkler technology, and in particular to a fire sprinkler that is easy to connect. Background Technology
[0002] As the terminal actuator of an automatic fire suppression system, the reliability and ease of connection between fire sprinklers and fire extinguishing pipelines directly affect the system's installation efficiency, maintenance costs, and response effectiveness during a fire. They are widely used in various locations such as residential buildings, commercial buildings, industrial plants, and warehousing and logistics facilities. According to fire safety regulations, fire sprinklers must be securely connected to the water distribution branch pipes, and the connection points must have good sealing properties to prevent extinguishing agent leakage that could lead to fire suppression failure. Currently, the mainstream connection method between fire sprinklers and pipelines is still threaded connection, with some large-diameter sprinklers using flange connections.
[0003] A fire sprinkler head that is easy to connect is disclosed in publication number CN222517639U. This fire sprinkler head includes: a main body comprising a yoke arm seat, a threaded tube on one side of the yoke arm seat, and a yoke arm frame fixedly connected to the other side of the yoke arm seat; the surface of the yoke arm frame is fitted with a glass body and a deflector plate; and a rotating mechanism including a connecting rod. This invention, by providing a rotating mechanism on the surface of the yoke arm seat, allows for installation of the fire sprinkler head without the use of a wrench, simply by rotating the connecting rod around the fire sprinkler head. Furthermore, by opening the rotating rod and rotating the connecting rod and the sleeve, the fire sprinkler head can be installed and connected more quickly and effortlessly even in situations with limited installation space. By separating the yoke arm seat and the threaded tube, the threaded tube can be retained for continued use when the fire sprinkler head is replaced after being triggered.
[0004] Currently, threaded connections require wrapping Teflon tape or applying sealant to the nozzle interface, followed by repeated tightening with a wrench, making the installation of a single nozzle time-consuming. Flange connections require aligning bolt holes, inserting bolts, and tightening them one by one, necessitating multiple people to install a single flanged nozzle. Furthermore, these procedures demand high skill levels from installers; loosely wrapped Teflon tape can lead to leaks, while overly tight tape can damage the interface threads. Uneven preload on flange bolts can cause deformation of the sealing surface. Both threaded and flanged connections are inefficient and rely heavily on specialized expertise. Utility Model Content

[0009] As a further embodiment of this utility model, a connector is inserted into one side of the connection port, and an annular sealing ring is provided inside the connector. The annular sealing ring serves to seal the connection port.
[0010] As a further embodiment of this utility model, support blocks are fixedly connected to both sides of the connector, and a connecting rod is fixedly connected to one side of the support block. The connecting rod serves to support and fix the plate.
[0011] As a further embodiment of this utility model, a fixed cylinder is rotatably connected to the surface of the connecting rod. The fixed cylinder is fixedly connected to one side of the fixed plate, and the fixed plate serves to support the telescopic plate.
[0012] As a further embodiment of this utility model, limit blocks are fixedly connected to both sides of the surface of the telescopic plate. The limit blocks are slidably connected in the grooves opened inside the fixed plate. The grooves serve to limit the position of the limit blocks.

[0015] (III) Beneficial Effects
[0016] This utility model provides a fire sprinkler head that is easy to connect, and has the following beneficial effects:
[0017] 1. This easy-to-connect fire sprinkler head, through the setting of a positioning mechanism, positioning block and tensioning mechanism, allows for quick assembly and disassembly of the fire sprinkler head body and the connecting parts. The connection is made possible by inserting the connector into the connector, then stretching the telescopic plates on both sides of the connector, which moves the positioning block on one side of the telescopic plate to the appropriate position. After releasing the handle, the locking block on the handle side is subjected to the reverse force provided by the torsion springs on both sides, which firmly inserts it into the locking groove on the surface of the positioning block. This effectively solves the problem of cumbersome assembly and disassembly and disassembly and the reliance on tools in traditional threaded or flanged connections.
[0018] 2. This easily connectable fire sprinkler head features a water pressure detection mechanism. Multiple miniature pressure sensors are installed on one side of the connection port to monitor the water pressure in real time. If the water pressure is too high or too low, the signal is transmitted to a PLC controller on one side. The PLC controller then activates an alarm light, achieving real-time monitoring of the water pressure at the connection port and timely warning of abnormalities. This ensures the stable operation of the fire sprinkler head and the reliability of its fire extinguishing capabilities. Attached Figure Description

One side of the PLC controller 302 is electrically connected to an alarm light 303 via a power cord. The positioning mechanism 4 includes a fixed connector 401 fixedly connected to both sides of the surface of the connection port 2. A fixed sleeve 402 is fixedly connected to the surface of the fixed connector 401. A torsion spring 403 is fixedly connected inside the fixed sleeve 402. A locking block 404 is fixedly connected to one side of the torsion spring 403. A handle 14 is fixedly connected to one side of the locking block 404.

Then, the other end of the threaded connector 13 is screwed tightly to the external connection structure to complete the overall connection.
[0028] In this invention, the working steps of the device are as follows:
[0029] First step: When using, insert the connector 2 into the connector 7, then stretch the telescopic plates 601 on both sides of the connector 7 so that the positioning block 5 on one side of the telescopic plate 601 moves to the appropriate position. Then release the handle 14 after pressing, so that the locking block 404 on one side of the handle 14 is subjected to the reverse force provided by the torsion springs 403 on both sides, and can be firmly inserted into the slot on the surface of the positioning block 5.
[0030] The second step: During use, multiple miniature pressure sensors 301 are installed on one side of the connection port 2. The miniature pressure sensors 301 detect the water pressure at the interface in real time. If the water pressure is too high or too low, the signal is transmitted to the PLC controller 302 on one side, and then the PLC controller 302 controls the alarm light 303 to issue an alarm.
