[0006] To achieve the above objectives, this utility model provides the following technical solution: an easily detachable fire sprinkler, comprising: a supporting housing, and a nozzle disposed on the left side of the supporting housing, and further comprising:

[0007] A positioning rod is installed inside the support housing, and a ball valve is provided on the upper side of the positioning rod. A limit ring is provided on the outer side of the ball valve, and a first sealing ring is provided on the inner side of the limit ring. An operating rod is provided on the upper side of the limit ring, and a guide ring is provided in the middle of the operating rod. A switch mark is provided on the outer side of the operating rod. An inlet is provided on the right side of the support housing, and a connecting pipe body is provided on the right side of the inlet. A second sealing ring is provided on the left side of the connecting pipe body, and a connecting block is provided on the outer side of the connecting pipe body. A connecting component is provided on the left side of the connecting block. A probe is provided on the left side of the ball valve, and a pressure gauge is connected to the upper side of the probe. Rifling is provided inside the nozzle, and a limit rod is provided on the outer side of the nozzle. A gripping rod is provided at the lower end of the support housing.

[0008] In one possible implementation, the connecting assembly includes a pressing plate mounted on the left side of the connecting block, with a limit plate provided on the inner side of the pressing plate, a guide block provided in the middle of the pressing plate, and a damper provided on the inner side of the limit plate.

[0009] In one possible implementation, the connecting block and the limiting plate are engaged relative to each other, and the connecting block is symmetrically arranged about the central axis of the connecting pipe body.

[0010] In one possible implementation, the pressing plate and the guide block are slidably arranged relative to each other, and the pressing plate and the central axis of the supporting housing are arranged symmetrically vertically.

[0011] In one possible implementation, the ball valve and the positioning rod are rotatably arranged relative to each other, and the limiting rings are symmetrically arranged about the central axis of the ball valve.

[0012] In one possible implementation, the switch mark is engaged with the support housing, and the switch mark is symmetrically arranged about the central axis of the operating lever.

[0013] In one possible implementation, the limiting rod is threadedly connected to both the nozzle and the support housing, and the limiting rod is symmetrically arranged about the central axis of the support housing, with the rifling grooves being opened at equal angles inside the nozzle.

[0014] In one possible implementation, a support ring is provided on the right side of the nozzle, and a third sealing ring is provided on the right side of the support ring.

[0015] In one possible implementation, the third sealing ring is engaged with the support ring, and the longitudinal section of the support ring is an annular structure.

[0016] Compared with the prior art, the beneficial effects of this utility model are: This easy-to-disassemble fire sprinkler facilitates disassembly and maintenance after use, making it easy to replace damaged parts, thus avoiding impacts on maintenance efficiency and reducing maintenance costs. Furthermore, it allows for quick connection to pipelines before use, saving operators time and ensuring efficient firefighting and rescue operations, thereby improving overall efficiency and performance. Specifically, as shown below:

[0017] The damper, in conjunction with the guide block, pushes the limiting plate outward, causing the limiting plate to engage with the connecting block and fix the connecting pipe body to the right side of the support shell. This allows operators to more quickly and conveniently complete the connection work between the support shell and the connecting pipe body when using the device, thus improving the efficiency of the device.

[0018] The ball valve is rotated along the positioning rod inside the support housing by the operating lever and the guide ring. This allows the ball valve to cut off the flow of extinguishing agent inside the support housing, making it easy for operators to switch the device on and off and reducing the consumption of extinguishing agent.

[0019] By rotating the limiting rod, the limiting rod is released from its restriction on the nozzle, making it easier for the operator to remove the nozzle to the left, thereby improving the efficiency of disassembly and maintenance of the device, reducing maintenance costs, and extending the service life of the device.

[0020] By using nozzles and rifling to guide the high-pressure extinguishing agent, the extinguishing agent is sprayed more concentratedly to the left, which increases the extinguishing radius under the same pressure. At the same time, the presence of rifling can still concentrate the extinguishing agent when the pressure is low, thus improving the efficiency of the device.

[0021] By using a support ring in conjunction with a third sealing ring to seal the gap between the nozzle and the support housing, the extinguishing agent is less likely to seep outwards from the gap between the two, thus improving the safety of the device. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-6 This utility model provides a technical solution: an easy-to-disassemble fire sprinkler, comprising: a supporting shell 1, and a nozzle 16 disposed on the left side of the supporting shell 1, and further comprising:

[0031] A positioning rod 2 is installed inside the supporting housing 1. A ball valve 3 is installed on the upper side of the positioning rod 2. A limit ring 4 is installed on the outer side of the ball valve 3. A first sealing ring 5 is installed on the inner side of the limit ring 4. An operating rod 6 is installed on the upper side of the limit ring 4. A guide ring 7 is installed in the middle of the operating rod 6. A switch mark 8 is installed on the outer side of the operating rod 6. An inlet 9 is opened on the right side of the supporting housing 1. A connecting pipe body 10 is installed on the right side of the inlet 9. A second sealing ring 11 is installed on the left side of the connecting pipe body 10. A connecting block 12 is installed on the outer side of the connecting pipe body 10. A connecting component 13 is installed on the left side of the connecting block 12. A probe 14 is installed on the left side of the ball valve 3. A pressure gauge 15 is connected to the upper side of the probe 14. A rifling 17 is opened inside the nozzle 16. A limit rod 20 is installed on the outer side of the nozzle 16. A gripping rod 21 is installed at the lower end of the supporting housing 1, which constitutes a complete fire sprinkler.

[0032] like Figure 3 , Figure 4 and Figure 5 As shown, the connecting assembly 13 includes a pressing plate 1301 installed on the left side of the connecting block 12, and a limiting plate 1302 is provided on the inner side of the pressing plate 1301. A guide block 1303 is provided in the middle of the pressing plate 1301, and a damper 1304 is provided on the inner side of the limiting plate 1302. The connecting block 12 and the limiting plate 1302 are engaged relative to each other, and the connecting block 12 is symmetrically arranged vertically about the central axis of the connecting pipe body 10. The pressing plate 1301 and the guide block 1303 are slidably arranged relative to each other, and the pressing plate 1301 is symmetrically arranged vertically about the central axis of the supporting shell 1. By pressing the pressing plate 1301 inward, the pressing plate 1301 pushes the limiting plate 1302 inward along the guide block 1303 to squeeze the damper 1304. At this time, the connecting pipe body 10 is installed on the right side of the support shell 1. At the same time, the pressing of the pressing plate 1301 is released, causing the damper 1304 to rebound and push the limiting plate 1302 outward to reset and engage with the connecting block 12, thus fixing the connecting pipe body 10 on the right side of the support shell 1. This completes the quick connection between the support shell 1 and the connecting pipe body 10, improving the efficiency of the device.

[0033] like Figure 1 and Figure 2 As shown, the ball valve 3 and the positioning rod 2 are rotatably arranged relative to each other, and the limiting ring 4 is symmetrically arranged about the central axis of the ball valve 3. The switch mark 8 is engaged with the supporting housing 1, and the switch mark 8 is symmetrically arranged about the central axis of the operating rod 6. By rotating the operating rod 6 along the guide ring 7, the operating rod 6 pushes the ball valve 3 to rotate inside the supporting housing 1. The ball valve 3 cuts off the flow of the extinguishing agent inside the supporting housing 1, thereby completing the convenient opening and closing of the device.

[0034] like Figure 1 and Figure 2 As shown, the limiting rod 20 is threadedly connected to both the nozzle 16 and the support housing 1. The limiting rod 20 is symmetrically arranged about the central axis of the support housing 1, and the rifling 17 is opened at equal angles inside the nozzle 16. After the device is used, the limiting rod 20 is rotated to release its restriction on the nozzle 16, making it easier for the operator to remove the nozzle 16 to the left, thereby improving the efficiency of disassembly and maintenance of the device and reducing maintenance costs.

[0035] like Figure 1 , Figure 2 and Figure 6As shown, a support ring 18 is provided on the right side of the nozzle 16, and a third sealing ring 19 is provided on the right side of the support ring 18. The third sealing ring 19 is engaged with the support ring 18, and the longitudinal section of the support ring 18 is a circular structure. The rifling 17, which is opened at equal angles inside the nozzle 16, guides the high-pressure ejected extinguishing agent, making the extinguishing agent sprayed more concentrated to the left. This increases the extinguishing radius under the same pressure. At the same time, the presence of the rifling 17 can still make the extinguishing agent more concentrated when the pressure is low, thus improving the efficiency of the device. At the same time, the support ring 18 and the third sealing ring 19 on the right side of the nozzle 16 seal the gap between the nozzle 16 and the support housing 1, making it difficult for the extinguishing agent to seep outward from the gap between the two, thus improving the safety of the device.
