Description

Technical Field

[0001] This utility model relates to the field of fire protection technology for building construction, and in particular to a sprinkler system for fire protection in building construction. Background Technology

[0002] Fire sprinkler heads are used in fire sprinkler systems. When a fire occurs, water is sprayed out through the sprinkler head's splash plate to extinguish the fire and prevent it from spreading. In scenarios where flammable materials are used on the walls, a sprinkler device that can be tilted to spray water onto the walls is needed.

[0003] A search revealed Chinese Patent Publication No. CN221637210U, which discloses a fire sprinkler device. The device includes a mounting plate, a fixed box at the bottom of the mounting plate, and a sprinkler head at the bottom of the fixed box. The mounting plate contains a translation mechanism for moving the fixed box laterally. A connecting rope is attached to the top of the sprinkler head. A winch mechanism for winding or unwinding the connecting rope is located on the top inner side of the fixed box. A pushing mechanism for swinging the sprinkler head is also located within the fixed box. This invention uses the winch mechanism to wind or unwind the connecting rope, causing the sprinkler head to rise and fall. The lowered sprinkler head sprays more concentrated water, enabling rapid extinguishing of lower-level flames and improving fire suppression. Users can control the spray range by raising and lowering the sprinkler head. The device has a compact overall structure, making it suitable for installation in confined spaces such as indoors. However, in actual installation, the device can only spray at the height of the sprinkler head and cannot adjust the tilt angle or spray direction, limiting its application and making it unsuitable for controlling flammable wall materials. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a sprinkler device for fire protection in buildings, aiming to improve the problem that the existing technology can only spray the sprinkler head at a certain height and cannot adjust the tilt angle and spray direction of the sprinkler head, thus limiting the application scenarios of the sprinkler head.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a fire sprinkler system for building construction, comprising a branch pipe and a support base. The front end of the branch pipe is connected to a corrugated pipe, the right end of the corrugated pipe is connected to a connecting pipe, the right end of the connecting pipe is connected to a flexible hose, and the right end of the flexible hose is connected to a sprinkler head. The sprinkler head is rotatably connected to the inner wall of the support base. A vertical rod is rotatably connected to the top of the support base. A height adjustment component is provided at the top of the vertical rod. A gear is fixedly connected to the outer wall of the vertical rod. A limit frame is fixedly connected to the front top of the support base. A pull rod is slidably connected to the inner wall of the limiting frame. A toothed block is fixedly connected to the rear end of the pull rod. The toothed block is slidably connected to the branch pipe and engages with the gear. A spring is fixedly connected to the front side of the toothed block. The front end of the spring is fixedly connected to the limiting frame. A threaded sleeve is rotatably connected to the right side of the inner wall of the support base. A lead screw is threadedly connected to the inner wall of the threaded sleeve. A ball head is fixedly connected to the bottom of the lead screw. A ball seat is fixedly connected to the top of the spray head. The ball seat is slidably connected to the ball head. An adjustment mechanism is provided at the top of the connecting pipe.

[0006] Through the above technical solution: the branch pipe, as the key water source channel, is connected to the corrugated pipe. The corrugated pipe has flexible characteristics, which allows the connecting pipe to flexibly adapt to different installation angles, effectively improving the installation adaptability of the device in complex environments. The connecting pipe connects to the hose and the sprinkler head in sequence, undertaking the responsibility of delivering water to the sprinkler head so that the sprinkler head can spray water. The sprinkler head is set on the inner wall of the support base by a rotating connection. This design facilitates the adjustment of the spray direction and enhances the controllability of the spray coverage area. The top of the support base is rotatably connected to the upright, and the gear on the outer wall of the upright can slide within the limit frame. The toothed blocks at the rear end of the pull rod engage with each other. Pulling the pull rod unlocks or locks the gears, thereby rotating or fixing the support base. This allows for further adjustment of the spray head's rotation angle. Additionally, the threaded sleeve rotating on the right side of the support base's inner wall is threadedly connected to the lead screw. The ball head at the bottom of the lead screw is slidably connected to the ball seat at the top of the spray head. When the threaded sleeve is rotated, the lead screw drives the ball head to move, causing the spray head to rotate around its connection point with the support base, thus adjusting the tilt angle. The adjustment mechanism at the top of the connecting pipe allows for fine adjustment of the connecting pipe's height to better suit the overall spraying needs.

[0007] As a further description of the above technical solution:

[0008] The adjusting mechanism includes two fixed rings. The inner walls of the two fixed rings are respectively fixedly connected to the top left and right sides of the outer wall of the connecting pipe. A threaded rod is fixedly connected to the top of each of the two fixed rings. A hollow rod is slidably connected to the top of the outer wall of each of the two threaded rods. A positioning plate is fixedly connected to the top of each of the two hollow rods. A slider is fixedly connected to the left and right sides of the outer wall of each of the two threaded rods. A sliding groove is slidably connected to the left and right sides of the inner wall of each of the two hollow rods. Multiple sliders are slidably connected to the corresponding sliding grooves. A rotating sleeve is rotatably connected to the bottom of each of the two hollow rods. The two rotating sleeves are threadedly connected to the corresponding threaded rods.

[0009] The above technical solution involves an upward-extending threaded rod that forms a sliding connection with a hollow rod. This structure provides a vertical guide path for adjusting the height of the connecting pipe, ensuring a clear direction of movement during height adjustment. Slider blocks are fixedly installed on the left and right sides of the outer wall of the threaded rod, while corresponding grooves are installed on the left and right sides of the inner wall of the hollow rod. The sliders and grooves are precisely matched and slidably connected. This connection method serves a dual purpose: firstly, it restricts the rotation of the threaded rod, and secondly, it ensures smooth vertical movement of the threaded rod within the hollow rod. A rotating sleeve is rotatably connected to the bottom of the hollow rod, and the rotating sleeve is threadedly connected to the threaded rod. When the rotating sleeve is rotated, based on the principle of threaded transmission, the rotational motion of the rotating sleeve is converted into the vertical linear motion of the threaded rod within the hollow rod. Since the threaded rod is fixedly connected to a fixed ring, and the fixed ring is tightly connected to the connecting pipe, the vertical movement of the threaded rod will cause the fixed ring and the connecting pipe to rise and fall synchronously, thereby achieving precise height adjustment of the connecting pipe to meet the actual needs of fire sprinkler systems in different building scenarios.

[0010] As a further description of the above technical solution:

[0011] The height adjustment assembly includes a sleeve, the inner wall of which is slidably connected to the top of the outer wall of the upright. A fixing plate is fixedly connected to the top of the sleeve, and bolts are threaded to the left and right sides of the bottom of the fixing plate. The front and rear sides of the outer wall of the upright are provided with reserved slots. A spring is fixedly connected to the inner wall of each of the two reserved slots. A locking block is fixedly connected to the front end of each of the two springs. The two locking blocks are slidably connected to the corresponding reserved slots. The front and rear sides of the outer wall of the sleeve are provided with multiple reserved holes, and the two locking blocks engage with the two reserved holes at the bottom.

[0012] The above technical solution allows for height adjustment of the upright pole using a height adjustment assembly. Within this assembly, a sleeve is fitted onto the top of the upright pole, and a fixing plate is fixed to the top of the sleeve. Bolts secure the fixing plate to a wall or other supporting surface, ensuring the stability of the entire device. A spring on the upright pole works in conjunction with a locking block, which slides within a pre-drilled groove and engages with pre-drilled holes at different locations on the sleeve, thereby adjusting the height of the support base and sprinkler head.

[0013] As a further description of the above technical solution:

[0014] A mounting box is fixedly connected to the bottom of the support base, and a smoke detector is fixedly connected to the inner wall of the mounting box.

[0015] The above technical solution involves a smoke detector that monitors the ambient smoke concentration in real time. When the concentration reaches a set value, it sends a signal to trigger the sprinkler system to start, enabling timely water spraying for fire extinguishing.

[0016] As a further description of the above technical solution:

[0017] Fireproof cotton is fixedly connected to the outer wall of the hose, and fastening rings are fixedly connected to both the left and right sides of the outer wall of the fireproof cotton.

[0018] The above technical solution involves fireproof cotton on the outer wall of the hose, which can effectively block heat and prevent flames from spreading to the hose, ensuring the safety of the water supply line. The fastening rings on both sides firmly fix the fireproof cotton to the hose, enabling the fireproof cotton to stably perform its fireproof function and ensuring the safety of related facilities.

[0019] As a further description of the above technical solution:

[0020] A shock-absorbing pad is fixedly connected to the top of the fixing plate, and the top ends of the two bolts both penetrate the shock-absorbing pad.

[0021] The above technical solution uses a shock-absorbing pad to buffer vibrations and reduce the impact on the fixed wall surface. Bolts penetrate the shock-absorbing pad to achieve stable installation of the fixed plate.

[0022] As a further description of the above technical solution:

[0023] Multiple anti-slip strips are fixedly connected to the outer walls of both rotating sleeves, and the spacing between adjacent anti-slip strips is equal.

[0024] The above technical solution involves an anti-slip strip on the outer wall of the rotating sleeve, which increases the friction between the hand and the rotating sleeve during rotation, making it easier for people to accurately rotate the rotating sleeve and adjust the height of the connecting pipe.

[0025] As a further description of the above technical solution:

[0026] The front end of the pull rod is slidably connected to a pull ring, and the surface of the pull ring is treated with an anti-slip coating.

[0027] The above technical solution involves an anti-slip treatment on the pull ring at the front end of the pull rod, making it easy for operators to grip and pull the rod, thereby adjusting the rotation angle of the support base.

[0028] As a further description of the above technical solution:

[0029] This utility model has the following beneficial effects:

[0030] 1. In this utility model, the corrugated pipe enables the connecting pipe to adapt to different curved installation surfaces, improving installation flexibility. Through the interaction of the pull rod, toothed block, spring and gear, the rotation angle of the support can be adjusted, which drives the spray head to rotate to adjust the spray direction. In addition, the threaded sleeve, lead screw, ball head and ball seat work together to realize the adjustment of the spray head tilt angle, which comprehensively improves the problem of the single adjustment function of the spray head and the limited application scenarios in the prior art.

[0031] 2. In this utility model, when the rotating sleeve is rotated, based on the threaded transmission, under the restriction of the slider and the groove, the threaded rod can only move up and down inside the hollow rod. Since the threaded rod is connected to the fixed ring, and the fixed ring is sleeved on the top of the connecting pipe, the threaded rod drives the fixed ring and the connecting pipe to rise and fall synchronously, so as to achieve precise adjustment of the height of the connecting pipe. This design can flexibly and accurately adjust the height of the connecting pipe as needed, and improve the applicability and effectiveness of the sprinkler device in different fire-fighting scenarios.

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.

[0043] Reference Figure 3 , Figure 4 and Figure 5This utility model provides an embodiment of a fire sprinkler system for building construction, comprising a branch pipe 1 and a support base 7. The branch pipe 1, as a component connected to the main fire water supply pipeline, is responsible for introducing water into the entire sprinkler system. The support base 7 provides an installation and support foundation for components such as the sprinkler heads 6, ensuring the stability of the device. The front end of the branch pipe 1 is connected to a corrugated pipe 3, and the right end of the corrugated pipe 3 is connected to a connecting pipe 4. The corrugated pipe 3 allows for multi-angle connections between the connecting pipe 4 and the branch pipe 1 to adapt to different installation environments and spatial layouts. The right end of the connecting pipe 4 is connected to a flexible hose 5, which has a certain degree of flexibility and can be bent freely within a certain range to facilitate adjustment of the position of the sprinkler heads 6. The right end of the flexible hose 5 is connected to the sprinkler heads 6, which are responsible for spraying the introduced water as a mist. The spray is applied evenly to achieve fire extinguishing. The sprinkler head 6 is rotatably connected to the inner wall of the support base 7, allowing the sprinkler head 6 to be angled within the support base 7, thereby expanding the spray coverage area. A vertical rod 8 is rotatably connected to the top of the support base 7, providing vertical support for the support base 7 and allowing the horizontal angle of the support base 7 and sprinkler head 6 to be changed by rotation. A height adjustment component is installed at the top of the vertical rod 8 to adjust the vertical height of the vertical rod 8 and support base 7. A gear 9 is fixedly connected to the outer wall of the vertical rod 8, engaging with a toothed block 12 to control the rotation angle of the support base 7, thus positioning the sprinkler head 6 horizontally. A limit bracket 10 is fixedly connected to the top front of the support base 7, providing a sliding track for the pull rod 11. The movement range of the pull rod 11 is limited. The pull rod 11 is slidably connected to the inner wall of the limiting frame 10. A toothed block 12 is fixedly connected to the rear end of the pull rod 11. The toothed block 12 is slidably connected to the branch pipe 1. The pull rod 11 slides within the limiting frame 10, driving the toothed block 12 to move, thereby locking and unlocking the gear 9. The toothed block 12 engages with the gear 9. Engaging or disengaging the toothed block 12 with the gear 9 allows the support seat 7 to rotate and be fixed. A spring 13 is fixedly connected to the front side of the toothed block 12. The front end of the spring 13 is fixedly connected to the limiting frame 10, serving as a buffer and reset function. After the pull rod 11 pulls the toothed block 12 away from the gear 9, the toothed block 12 can automatically reset and engage with the gear 9 when the pull rod 11 is released. The inner wall of the support seat 7 is right A threaded sleeve 14 is rotatably connected to the side, which can cooperate with the spray head 6 to rotate. A screw 15 is threadedly connected to the inner wall of the threaded sleeve 14. A ball head 16 is fixedly connected to the bottom of the screw 15. When the screw 15 moves up and down, it can drive the ball head 16 to move up and down, thereby driving the spray head 6 to rotate through the ball seat 17. The top of the spray head 6 is fixedly connected to the ball seat 17. The ball seat 17 and the ball head 16 are slidably connected. The ball head 16 and the ball seat 17 cooperate so that the linear movement of the screw 15 can drive the spray head 6 to rotate around the ball seat 17 as the center, realizing the adjustment of the tilt angle. An adjustment mechanism 2 is provided at the top of the connecting pipe 4 for fine adjustment of the height of the connecting pipe 4, so that the entire spray device can better adapt to different space conditions and installation requirements during installation and use.The height adjustment assembly includes a sleeve 18, which is fitted onto the top of the outer wall of the upright 8, providing guidance and positioning for height adjustment. The inner wall of the sleeve 18 is slidably connected to the top of the outer wall of the upright 8. A fixing plate 19 is fixedly connected to the top of the sleeve 18 to secure the entire height adjustment assembly to the wall or other supporting structure of the building, ensuring the stability of the device. Bolts 20 are threaded onto the left and right sides of the bottom of the fixing plate 19. Reserved slots 21 are provided on the front and rear sides of the outer wall of the upright 8 to provide installation space for the spring 22 and the locking block 23. Springs 22 are fixedly connected to the inner wall of the groove 21. Each spring 22 has a locking block 23 fixedly connected to its front end. The locking block 23 provides elastic force so that it can automatically engage or disengage from the reserved hole 24 on the sleeve 18. The two locking blocks 23 are slidably connected to the corresponding reserved groove 21. Multiple reserved holes 24 are opened on the front and rear sides of the outer wall of the sleeve 18. The two locking blocks 23 engage with the two reserved holes 24 at the bottom. By engaging the locking blocks 23 with the reserved holes 24, the upright 8 is fixed at the required height position to ensure the stability of the height of the sprinkler head 6.

[0044] Specifically, branch pipe 1 serves as a water source channel, connecting to corrugated pipe 3. Corrugated pipe 3 is flexible, allowing connecting pipe 4 to adapt to different installation angles. Connecting pipe 4 sequentially connects hose 5 to sprinkler head 6, delivering water to sprinkler head 6 for spraying. Sprinkler head 6 is rotatably connected to the inner wall of support base 7 for easy adjustment of the spray direction. Support base 7 is rotatably connected to upright rod 8. Upright rod 8 is height-adjustable via a height adjustment assembly. In the height adjustment assembly, sleeve 18 is fitted onto the top of upright rod 8, and fixing plate 19 is fixed to the top of sleeve 18. Bolts 20 can be used to fix it to a wall or other supporting surface. Spring 22 on upright rod 8 cooperates with locking block 23, which can slide in the pre-drilled groove 21 and engage with pre-drilled holes 2 at different positions on sleeve 18. 4. Engagement is used to adjust the height of the support base 7 and the spray head 6. The gear 9 on the outer wall of the upright 8 engages with the toothed block 12 at the rear end of the sliding pull rod 11 inside the limit frame 10. Pulling the pull rod 11 can unlock or lock the gear 9, thereby rotating or fixing the support base 7 and further adjusting the rotation angle of the spray head 6. The threaded sleeve 14 rotating on the right side of the inner wall of the support base 7 is threadedly connected to the lead screw 15. The ball head 16 at the bottom of the lead screw 15 is slidably connected to the ball seat 17 at the top of the spray head 6. Rotating the threaded sleeve 14 can drive the ball head 16 through the lead screw 15, so that the spray head 6 rotates around the connection point with the support base 7 to adjust the tilt angle. The adjustment mechanism 2 at the top of the connecting pipe 4 can finely adjust the height of the connecting pipe 4 to adapt to the overall spraying requirements.

[0045] Reference Figure 2 , Figure 7 and Figure 8The adjusting mechanism 2 includes two fixing rings 201. The inner walls of the two fixing rings 201 are respectively fixedly connected to the top left and right sides of the outer wall of the connecting pipe 4 to securely connect the adjusting mechanism 2 and the connecting pipe 4. A threaded rod 202 is fixedly connected to the top of each of the two fixing rings 201, providing a vertical displacement basis for adjusting the height of the connecting pipe 4. A hollow rod 203 is slidably connected to the top of the outer wall of each of the two threaded rods 202, providing guidance for the up-and-down movement of the threaded rods 202. A positioning plate 204 is fixedly connected to the top of each of the two hollow rods 203 to fix the adjusting mechanism 2 in a specific position. Slider 205 is fixedly connected to both the left and right sides of the outer wall, which cooperates with the slide groove 206 to restrict the rotation of the threaded rod 202. The slide groove 206 is slidably connected to both the left and right sides of the inner wall of the two hollow rods 203. The slide groove 206 and the slider 205 are adapted to each other to provide a sliding track for the slider 205. Multiple sliders 205 are slidably connected to the corresponding slide groove 206 respectively. Rotating sleeve 207 is rotatably connected to the bottom of the two hollow rods 203. As a driving component, the rotation is converted into linear motion of the threaded rod 202, thereby realizing the adjustment of the height of the connecting pipe 4. The two rotating sleeves 207 are threadedly connected to the corresponding threaded rods 202 respectively.

[0046] Specifically, the threaded rod 202 at the top of the fixing ring 201 extends upward and slides with the hollow rod 203, providing a vertical guide path for the height adjustment of the connecting pipe 4. The sliders 205 on the left and right sides of the outer wall of the threaded rod 202 precisely match and slide with the sliding grooves 206 on the left and right sides of the inner wall of the hollow rod 203, which not only restricts the rotation of the threaded rod 202, but also ensures that it can move up and down smoothly in the hollow rod 203. When the rotating sleeve 207 is rotated, based on the thread transmission principle, the threaded rod 202 is driven to move up and down in the hollow rod 203, thereby driving the fixing ring 201 and the connecting pipe 4 to rise and fall synchronously, realizing the precise adjustment of the height of the connecting pipe 4 to meet the fire sprinkler requirements in different scenarios.

[0047] Reference Figure 1 , Figure 2 and Figure 6 The bottom of the support base 7 is fixedly connected to the mounting box 25, and the inner wall of the mounting box 25 is fixedly connected to the smoke detector 26, which monitors the smoke concentration of the surrounding environment in real time and sends a signal when the smoke concentration reaches the set value; the outer wall of the hose 5 is fixedly connected to the fireproof cotton 27, which can effectively block heat and prevent the flame from spreading to the hose 5. The left and right sides of the outer wall of the fireproof cotton 27 are fixedly connected to the fastening rings 28, which firmly fix the fireproof cotton 27 to the hose 5;

[0048] Specifically, the smoke detector 26 monitors the smoke concentration in the surrounding environment in real time. When the smoke concentration reaches the set value, it sends a signal to trigger the sprinkler system to start and spray water to extinguish the fire in time. The fireproof cotton 27 on the outer wall of the hose 5 can effectively block heat and prevent the flame from spreading to the hose 5, ensuring the safety of the water supply line. The fastening rings 28 on both sides firmly fix the fireproof cotton 27 to the hose 5 to ensure the stable performance of the fireproof function.

[0049] Reference Figure 1 , Figure 2 and Figure 6 A shock-absorbing pad 29 is fixedly connected to the top of the fixed plate 19 to buffer the vibration generated during the operation of the device. The tops of the two bolts 20 penetrate the shock-absorbing pad 29. Multiple anti-slip strips 30 are fixedly connected to the outer walls of the two rotating sleeves 207 to increase the friction between the hand and the rotating sleeves 207 during rotation. The spacing between adjacent anti-slip strips 30 is equal. A pull ring 31 is slidably connected to the front end of the pull rod 11. The surface of the pull ring 31 is treated with anti-slip material to facilitate the operator's grip and pull of the pull rod 11.

[0050] Specifically, the shock-absorbing pad 29 can buffer the vibration generated during the operation of the device and reduce the impact on the fixed wall surface, etc. The bolt 20 passes through the shock-absorbing pad 29 to achieve a stable installation of the fixing plate 19. The anti-slip strip 30 on the outer wall of the rotating sleeve 207 increases the friction between the hand and the rotating sleeve 207 when rotating, allowing people to rotate the rotating sleeve 207 more easily and accurately to adjust the height of the connecting pipe 4. The anti-slip pull ring 31 at the front end of the pull rod 11 makes it easy for the operator to grip and pull the pull rod 11 to adjust the rotation angle of the support seat 7.

[0051] Working principle: First, the branch pipe 1 is connected to the main pipe. The corrugated pipe 3 connected to the front end of the branch pipe 1 allows the connecting pipe 4 to bend relative to the branch pipe 1, thereby adapting to installation surfaces with different degrees of curvature and improving the installation flexibility of the device. Next, the fixing plate 19 is fixed to the wall to provide stable support for the entire device. When it is necessary to adjust the height of the sprinkler head 6, the structural feature of the rotating connection between the upright 8 and the support base 7 is utilized. Specifically, the two locking blocks 23 are first pressed into the reserved groove 21 to release the restriction on the vertical movement of the sleeve 18 on the upright 8. Then, the upright 8 is moved vertically, causing the support base 7 to move up and down. After moving to the appropriate height, the height of the support base 7 is fixed by locking the locking blocks 23 into the reserved holes 24 at different heights, thereby adjusting the height of the sprinkler head 6. The rotation angle of the support base 7 is then adjusted. When the lever 11 is pulled forward, the toothed block 12 connected to the rear end of the lever 11 will squeeze the spring 13, thereby releasing the restriction of the toothed block 12 on the gear 9. At this time, the support base 7 is rotated, which drives the spray head 6 connected to it to rotate together to adjust the spray direction. After the rotation angle is adjusted, the lever 11 is released. Under the elastic force of the spring 13, the toothed block 12 is pushed to move backward and engage in the tooth groove of the gear 9, thereby locking the gear 9. Since the threaded sleeve 14 and the spray head 6 are rotatably connected to the support base 7, when the threaded sleeve 14 is rotated, its inner wall is threadedly connected to the screw 15, and the threaded sleeve 14 will move up and down. The ball head 16 at the bottom of the screw 15 is slidably connected to the ball seat 17 at the top of the spray head 6, so that the spray head 6 rotates with its connection with the support base 7 as the center, thereby realizing the adjustment of the tilt angle of the spray head 6.

[0052] Furthermore, when the height of the connecting pipe 4 needs to be adjusted, since the rotating sleeve 207 and the threaded rod 202 are threadedly connected, and the threaded rod 202 has sliders 205 fixed on both sides, and these sliders 205 are slidably connected to the grooves 206 on the left and right sides of the inner wall of the hollow rod 203, the rotation of the threaded rod 202 itself is restricted. When the rotating sleeve 207 is rotated, based on the principle of threaded transmission, the threaded rod 202 cannot rotate under the restriction of the sliders 205 and the grooves 206, and can only move up and down within the hollow rod 203. Since the inner walls of the two fixing rings 201 are fixed to the top left and right sides of the outer wall of the connecting pipe 4, and the bottom of the threaded rod 202 is fixedly connected to the top of the fixing rings 201, the up and down movement of the threaded rod 202 will drive the fixing rings 201 to move synchronously, thereby causing the connecting pipe 4 within the fixing rings 201 to move up and down, ultimately achieving precise adjustment of the height of the connecting pipe 4. This design can flexibly and accurately adjust the height of the connecting pipe 4 according to the needs of actual fire-fighting scenarios, improving the applicability and effectiveness of the sprinkler system.

[0053] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
