Description

Technical Field

[0001] This utility model relates to the field of fire sprinkler technology, specifically to a heat-sensing fire sprinkler head. Background Technology

[0002] Heat-sensitive fire sprinkler heads are part of a sprinkler system. In the event of a fire, the sprinkler heads on the sprinkler pipes spontaneously combust due to high temperatures. This triggers a water flow indicator installed on the sprinkler pipes, which sends a signal to the fire alarm control system controller to activate the sprinkler pump. This causes water to spray from the sprinkler heads, achieving the purpose of extinguishing the fire. Currently, most fire sprinkler heads have threads on their outer surface before being installed on the water pipes. Installing and removing fire sprinkler heads typically requires the installer to carry a wrench to tighten and loosen them, making the process inconvenient. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides a heat-sensing fire sprinkler head.

[0004] The technical solution adopted by this utility model to solve its technical problem is a heat-sensing fire sprinkler head, including a support. The top of the support is integrally formed with a connecting pipe, and the outer wall of the connecting pipe is provided with external threads. The bottom of the support is integrally formed with two support rods. A splash plate is provided below the support. The bottom ends of the two support rods are connected to the splash plate. A glass body is provided between the splash plate and the connecting pipe. A retainer is fixed on the support. Connecting rods are hinged to both sides of the retainer. The support is located between the two connecting rods.

[0005] By adopting the above technical solution, during installation, first connect the connecting pipe to the pipe threadedly, then manually rotate the two connecting rods until they are roughly horizontal. Hold the connecting rods to facilitate rotating the clamp. When the clamp is rotated, the support rotates accordingly, which facilitates tightening the connecting pipe. After the connecting pipe is installed, release the two connecting rods. The two connecting rods will return to their original shape under their own weight, without affecting the use of the nozzle. During disassembly, rotate the two connecting rods until they are roughly horizontal, then hold the connecting rods to facilitate loosening and disassembling the connecting pipe.

[0006] Specifically, both sides of the sleeve are integrally formed with limit blocks, the bottom ends of the two limit blocks are integrally formed with locking blocks, and the two connecting rods are provided with locking slots that are adapted to the locking blocks.

[0007] By adopting the above technical solution, when the two connecting rods are roughly in a horizontal state, the locking block is inserted into the locking groove on the connecting rod, which facilitates the positioning of the connecting rod. During installation or disassembly, even if the connecting rod is released, it will not rotate, which is conducive to gripping the connecting rod.

[0008] Specifically, the support is provided with a sealing gasket, which is located above the ferrule, and the bottom end of the sealing gasket is connected to the support by an adhesive.

[0009] By adopting the above technical solution, the sealing gasket can improve the sealing performance between the connecting pipe and the pipeline.

[0010] Specifically, both connecting rods have multiple anti-slip protrusions integrally formed on them.

[0011] By adopting the above technical solution, the anti-slip protrusions can increase the friction between the fingers and the linkage, making it easier to grip the linkage.

[0012] Specifically, the card sleeve has multiple anti-slip grooves on both sides.

[0013] By adopting the above technical solution, the anti-slip groove is designed to facilitate gripping the card sleeve.

[0014] Specifically, the ferrule is connected to the nozzle body by adhesive, and both the ferrule and the connecting rod are made of metal.

[0015] The beneficial effects of this utility model are:

[0016] The present invention relates to a heat-sensing fire sprinkler head. During installation, the connecting pipe is first threadedly connected to the pipeline. The two connecting rods are then manually rotated until they are roughly horizontal. Holding the connecting rods allows for easy rotation of the retaining sleeve. Rotating the retaining sleeve causes the support to rotate as well, facilitating the tightening of the connecting pipe. After the connecting pipe is installed, the two connecting rods are released, and they return to their original position under their own weight, without affecting the use of the sprinkler head. During disassembly, the two connecting rods are rotated until they are roughly horizontal, then held by hand to facilitate loosening and disassembling the connecting pipe.

[0017] The present invention relates to a heat-sensing fire sprinkler head. When the two connecting rods are in a roughly horizontal state, the locking block is inserted into the locking groove on the connecting rod, which facilitates the positioning of the connecting rod. During installation or disassembly, even if the connecting rod is released, it will not rotate, which is conducive to gripping the connecting rod. Attached Figure Description

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] For ease of installation and disassembly, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 As shown, the present invention provides a heat-sensing fire sprinkler head, comprising a support 1, a connecting pipe 11 integrally formed at the top of the support 1, the outer wall of the connecting pipe 11 having external threads, two support rods 10 integrally formed at the bottom of the support 1, a splash plate 12 provided below the support 1, the bottom ends of the two support rods 10 being welded to the splash plate 12, a glass body 13 being provided between the splash plate 12 and the connecting pipe 11, a retaining sleeve 2 being fixed on the support 1, and connecting rods 4 being hinged to both sides of the retaining sleeve 2, the support 1 being located between the two connecting rods 4.

[0025] During installation, first connect the connecting pipe 11 to the pipe thread. At this time, the connecting pipe 11 is not tightened. Manually rotate the two connecting rods 4. After the two connecting rods 4 are roughly horizontal, hold the connecting rods 4 to facilitate rotating the clamp 2. When the clamp 2 is rotated, the connecting pipe 11 rotates accordingly, which facilitates tightening the connecting pipe 11. After the connecting pipe 11 is installed, release the two connecting rods 4. The two connecting rods 4 will return to their original position under their own weight. Figure 1 This does not affect the use of the nozzle. When disassembling, rotate the two connecting rods 4. After the two connecting rods 4 are roughly horizontal, hold the connecting rods 4 to easily loosen and disassemble the connecting pipe 11.

[0026] To facilitate gripping link 4, for example, as shown Figure 1 As shown, both sides of the sleeve 2 are integrally formed with limit blocks 20, and the bottom ends of the two limit blocks 20 are integrally formed with a locking block 21. Both connecting rods 4 are provided with a locking groove that matches the locking block 21.

[0027] When in use, with the two connecting rods 4 in a roughly horizontal position, the two locking blocks 21 are inserted into the slots on the two connecting rods 4 to facilitate the positioning of the connecting rods 4. During installation or disassembly, even if the connecting rods 4 are released, the connecting rods 4 will not rotate or reset, making it easier to grip the connecting rods 4. After installation, pressing down on the connecting rods 4 will cause the locking blocks 21 to disengage from the slots on the connecting rods 4, facilitating the reset of the connecting rods 4.

[0028] To improve the sealing between the connecting pipe 11 and the pipeline, for example, such as Figure 1 As shown, the connecting pipe 11 is provided with a sealing gasket 3, which is located above the sleeve 2. The bottom end of the sealing gasket 3 is connected to the support 1 by adhesive.

[0029] When in use, after tightening the connecting pipe 11, the top of the sealing gasket 3 will be in close contact with the pipe, which can improve the sealing between the connecting pipe 11 and the pipe.

[0030] To facilitate gripping link 4, for example, as follows: Figure 1 As shown, both connecting rods 4 are integrally formed with multiple anti-slip protrusions 5.

[0031] To facilitate gripping the card holder 2, for example, as shown... Figure 1 As shown, the card sleeve 2 has multiple anti-slip grooves on both sides.

[0032] The sleeve 2 is connected to the nozzle body 1 by adhesive, and both the sleeve 2 and the connecting rod 4 are made of metal.

[0033] When using this utility model, first connect the connecting pipe 11 to the pipe thread. At this time, the connecting pipe 11 is not tightened. Manually rotate the two connecting rods 4. When the two connecting rods 4 are roughly in a horizontal state, the two locking blocks 21 are inserted into the locking slots on the two connecting rods 4 to facilitate the positioning of the connecting rods 4.

[0034] Holding the connecting rod 4 makes it easy to rotate the ferrule 2. When the ferrule 2 is rotated, the connecting pipe 11 rotates accordingly, which facilitates tightening the connecting pipe 11. The sealing gasket 3 improves the sealing between the connecting pipe 11 and the pipeline. After the connecting pipe 11 is installed, pressing down on the connecting rod 4 will disengage the locking block 21 from the slot on the connecting rod 4. The two connecting rods 4 will return to their original position under their own weight. Figure 1 This does not affect the use of the nozzle;

[0035] During disassembly, rotate the two connecting rods 4 upwards. When the two connecting rods 4 are roughly horizontal, insert the two locking blocks 21 into the locking slots on the two connecting rods 4. Hold the connecting rods 4 to easily loosen and disassemble the connecting pipe 11.
