[0002] Fire sprinkler hoses are crucial components of fire protection systems. To ensure the rapid activation and effective extinguishing of fires, protecting lives and property, fire sprinkler safety regulations encompass multiple aspects, guaranteeing system safety, reliability, and effectiveness. For instance, patent application CN202120870222.4 discloses a fire sprinkler hose where the inlet connector is threaded into the inlet pipe. While this threaded connection is common, it results in slow installation and is prone to leakage. Therefore, a fire sprinkler hose with fast installation and excellent sealing is urgently needed.

The ring-clamp sealed fire sprinkler metal hose greatly improves the installation speed through the setting of the ring-clamp joint, saving valuable time for fire fighting, and also greatly improves the sealing performance of the connection to prevent water leakage.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this utility model provides the following technical solution: a ring-clamp sealed fire sprinkler metal hose, comprising a stainless steel corrugated hose, one end of which is fixed with a ring-clamp connector, and the other end of which is fixed with a sprinkler nozzle.

[0007] Preferably, the ring clamp includes a first cylindrical portion fixedly connected to a stainless steel corrugated pipe, a first frustum portion fixed to the first cylindrical portion, a second cylindrical portion fixed to the first frustum portion, an annular protrusion fixed to the second cylindrical portion, a third cylindrical portion fixed to the annular protrusion, a second frustum portion fixed to the third cylindrical portion, and a fourth cylindrical portion fixed to the second frustum portion.

[0009] Preferably, the annular convex portion includes an arc-shaped convex section located at the middle position, with inclined sections connected to both ends of the arc-shaped convex section, and an arc-shaped concave section connected to the lower end of the inclined section.

[0010] Preferably, the spray nozzle includes a spray nozzle body, a circular ring plate is fixed on the spray nozzle body, and two centrally symmetrical fixing plates are fixed on the side wall of the circular ring plate, with through holes opened on the fixing plates.

[0011] Preferably, the annular protrusion includes an annular protruding wall and a sealing ring fixed to the inner wall surface of the annular protruding wall, with the inner wall surface of the sealing ring extending out of the groove of the annular protrusion.

[0012] Preferably, the diameter of the inner wall surface of the sealing ring gradually decreases from left to right.

[0013] Preferably, the inner wall surface of the sealing ring is configured as a continuous wavy shape.

[0015] Preferably, a portion of the clamping block extends beyond the rectangular groove, and the bottom surface of the clamping block is set as an arc-shaped surface that is higher on the left and lower on the right, and the spring is set to tilt to the left.

[0016] (III) Beneficial Effects

[0017] 1. This utility model greatly improves the installation speed with the water inlet pipe by setting the ring clamp joint, saving valuable time for fire fighting. At the same time, it greatly improves the sealing performance of the connection between the water inlet pipe and the ring clamp sealed fire sprinkler metal hose, which plays a good role in preventing water leakage.

[0018] 2. This utility model, through the setting of the second truncated cone and the first truncated cone, plays a good role in narrowing the diameter, thereby effectively squeezing and clamping the water inlet pipe inserted into the ring clamp connector. The water inlet pipe is clamped twice by the second truncated cone and the first truncated cone, and the first truncated cone has a greater degree of squeezing and limiting the water inlet pipe than the second truncated cone. This provides a good clamping and sealing effect for the water inlet pipe. In addition, the second truncated cone and the first truncated cone also play a good guiding and connecting role. The annular protrusion provides a good sealing effect for the water inlet pipe inserted therein, further improving the sealing performance.

[0019] 3. The present invention configures the annular convex part as being composed of an annular convex wall and a sealing ring. The annular convex part is configured as being composed of an arc-shaped convex section, an inclined section and an arc-shaped concave section. This configuration makes the sealing ring and the annular convex wall more firmly fixed. The inner wall surface of the sealing ring extends out of the groove of the annular convex part. In this way, when the water inlet pipe passes through the sealing ring, it exerts a squeezing effect on the sealing ring, so that the sealing ring is finally pressed tightly against the outer wall surface of the water inlet pipe, thereby achieving a good sealing effect.

[0020] 4. This utility model sets the inner wall diameter of the sealing ring to gradually decrease from left to right, and sets the inner wall surface of the sealing ring to a continuous wave shape, which not only facilitates the quick passage of the water inlet pipe through the sealing ring, but also further improves the sealing and fixing effect of the water inlet pipe.

[0021] 5. This utility model uses a clamping mechanism to ultimately limit and clamp the water inlet pipe. Attached Figure Description

Detailed Implementation

[0030] The following will refer to the appendix in the embodiments of this utility model. Figure 1-7 The technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0031] This utility model provides a technical solution: a ring-clamp sealed fire sprinkler metal hose, including a stainless steel corrugated hose 1, one end of which is fixed with a ring-clamp connector 2, and the other end of which is fixed with a sprinkler nozzle 3. In use, when it is necessary to connect the water inlet pipe to the ring-clamp sealed fire sprinkler metal hose, simply insert the water inlet pipe into the ring-clamp connector 2. Installation is very convenient. The water inlet pipe is tightly clamped within the ring-clamp connector 2, providing a good seal. Therefore, this utility model greatly improves the installation speed of the water inlet pipe through the ring-clamp connector 2, saving valuable time for firefighting. It also significantly improves the sealing performance at the connection between the water inlet pipe and the ring-clamp sealed fire sprinkler metal hose, effectively preventing leakage.

[0032] The ring-shaped connector 2 includes a first cylindrical portion 4 fixedly connected to a stainless steel corrugated pipe 1. The first cylindrical portion 4 is fixed with a first frustum 5. The first frustum 5 is fixed with a second cylindrical portion 6. The second cylindrical portion 6 is fixed with an annular protrusion 7. The annular protrusion 7 is fixed with a third cylindrical portion 8. The third cylindrical portion 8 is fixed with a second frustum 9. The second frustum 9 is fixed with a fourth cylindrical portion 10. The diameter of the end of the first frustum 5 connected to the first cylindrical portion 4 is smaller than the diameter of the end of the first frustum 5 connected to the second cylindrical portion 6. The diameter of the end of the second frustum 9 connected to the third cylindrical portion 8 is smaller than the diameter of the end of the second frustum 9 connected to the fourth cylindrical portion 10. The diameter of the end connected to the 10-cylinder joint is such that the outer diameters of the second cylindrical part 6 and the third cylindrical part 8 are equal. The second frustum part 9 and the first frustum part 4 effectively limit the diameter, thereby effectively squeezing and clamping the water inlet pipe inserted into the ring clamp joint 2. The water inlet pipe is clamped twice by the second frustum part 9 and the first frustum part 4, and the first frustum part 4 squeezes and limits the water inlet pipe to a greater extent than the second frustum part 9. This provides a good clamping and sealing effect for the water inlet pipe. In addition, the second frustum part 9 and the first frustum part 4 also serve as a good guide and connector. The annular protrusion 7 provides a good seal for the water inlet pipe inserted into it, further improving the sealing performance. Therefore, the ring clamp joint 2 with its left-end larger and right-end smaller structure greatly facilitates the insertion and clamping of the water inlet pipe and also greatly improves the sealing performance.

[0033] The annular protrusion 7 includes an arc-shaped protrusion 11 located in the middle position. Both ends of the arc-shaped protrusion 11 are connected to inclined sections 12. The lower end of the inclined section 12 is connected to an arc-shaped recessed section 13. By setting the annular protrusion 7, the annular protrusion 7 is relatively thick, which greatly improves the sealing effect on the water inlet pipe inserted therein.

[0034] The spray nozzle 3 includes a spray nozzle body 14, on which a circular ring plate 15 is fixed. Two centrally symmetrical fixing plates 16 are fixed to the side wall of the circular ring plate 15. The fixing plates 16 have through holes 17. The circular ring plate 15 and the fixing plates 16 provide convenient fixation for the spray nozzle 3 when needed. The inner wall of the water outlet end of the spray nozzle 3 can be provided with internal threads, which facilitates lengthening or changing the shape of the spray nozzle.

[0035] The annular protrusion 7 includes an annular protruding wall 18 and a sealing ring 19 fixed to the inner wall of the annular protruding wall 18. The inner wall of the sealing ring 19 extends out of the groove 20 of the annular protrusion 7. The annular protrusion 7 is configured with an arc-shaped protruding section 11, an inclined section 12, and an arc-shaped recessed section 13. This configuration makes the fixing of the sealing ring 19 to the annular protruding wall 18 more secure. Since the inner wall of the sealing ring 19 extends out of the groove 20 of the annular protrusion 7, it exerts a squeezing effect on the sealing ring 19 as the water inlet pipe passes through it, thus ultimately pressing the sealing ring 19 tightly against the outer wall of the water inlet pipe, thereby achieving a good sealing effect.

[0036] The inner wall diameter of the sealing ring 19 gradually decreases from left to right. This design allows the water inlet pipe to perform a gradual compression process on the sealing ring 19, which not only facilitates the passage of the water inlet pipe, but also makes the squeezing force of the sealing ring 19 on the outer wall of the water inlet pipe gradually increase from left to right, further improving the sealing and fixing effect of the water inlet pipe.

[0037] The inner wall of the sealing ring 19 is designed with a continuous wave shape. This design greatly reduces the contact area between the outer wall of the water inlet pipe and the inner wall of the sealing ring 19 when the water inlet pipe passes through the sealing ring 19, thus allowing the water inlet pipe to pass through the sealing ring 19 more quickly. In addition, the design forms a groove between two adjacent waves. When squeezed, the groove acts like a suction cup, which can effectively adsorb the water inlet pipe, thereby improving the sealing and fixing effect.

[0038] The inner wall of the first cylindrical part 4 is provided with several rectangular grooves 21. A clamping mechanism 22 is provided in the rectangular grooves 21. The clamping mechanism 22 includes a fixing rod 23 fixed between the two side walls of the rectangular groove 21. A clamping block 24 is rotatably connected to the fixing rod 23. Several springs 25 are fixed between the top wall of the clamping block 24 and the bottom wall of the rectangular groove 21. Through the setting of the clamping mechanism 22, the water inlet pipe is finally limited and clamped. When the water inlet pipe is inserted into the annular protrusion 7, when the water inlet pipe contacts the clamping block 24, it will squeeze the clamping block 24 until the spring 25 reaches its limit and the clamping block 24 can no longer rotate. This further improves the clamping and fixing of the water inlet pipe and provides good limitation of the water inlet pipe, avoiding unnecessary trouble caused by the water inlet pipe being inserted into the stainless steel corrugated hose 1.

[0039] Part of the clamping block 24 extends out of the rectangular groove 21, and the bottom surface of the clamping block 24 is set as an arc surface with the left side higher than the right side. The spring 25 is set to tilt to the left. The setting of the left-tilting spring 25 matches the direction of rotation of the clamping block 24 around the fixed rod 23. This can better compress the spring 25 and prevent the spring 25 from twisting.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
