Description

Technical Field

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

[0002] A fire sprinkler head is a fire-fighting device that is fixedly installed inside a building and can extinguish fires in a timely manner when a fire occurs.

[0003] Existing fire sprinklers consist of a frame with a deflector plate at one end and a connector at the other, with a nozzle on the connector. A glass tube is housed inside the frame. The deflector plate typically has a fastening screw, and the nozzle usually contains a sealing element. One end of the glass tube is inserted into the nozzle and contacts the sealing element, while the other end contacts the fastening screw. When a fire occurs in the building, the indoor temperature rises, and the liquid inside the glass tube absorbs heat and bursts, causing the sealing element to detach and opening the nozzle. Water then flows out through the nozzle and sprays onto the deflector plate, achieving the purpose of sprinkling water. However, because the glass tube is installed exposed inside the frame without any external protective structure, and because the tube wall is thin and the structure is relatively fragile, it is easily broken by minor bumps during transportation, resulting in poor durability. Utility Model Content

[0004] The purpose of this utility model is to provide a fire sprinkler head to solve the above-mentioned problems.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a fire sprinkler head includes a frame, a deflector plate at one end of the frame, a connecting seat at the other end, a pipe opening on the connecting seat, a glass tube inside the frame, an elastic element inside the pipe opening, a sealing element on the glass tube for inserting into the pipe opening and abutting against the elastic element, a threaded sleeve at the center of the deflector plate, a fastening screw threaded inside the threaded sleeve, a protective rubber sleeve detachably installed on the fastening screw, the protective rubber sleeve for wrapping the glass tube, and the protective rubber sleeve being made of rubber material.

[0006] As a further feature of this invention, a through hole is provided at the bottom of the protective sleeve, and a support plate is provided on the fastening screw. The support plate is used to pass through the through hole and be inserted into the interior of the protective sleeve. The diameter of the through hole is smaller than the diameter of the support plate.

[0007] As a further feature of this utility model, the connecting seat is provided with a groove communicating with the pipe opening, and the end of the protective sleeve away from the through hole is used to be inserted into the groove.

[0008] As a further feature of this invention, a first magnetic block is provided at the end of the protective sleeve away from the rotating disk, and a second magnetic block matching the first magnetic block is provided inside the groove.

[0009] As a further feature of this invention, the elastic element includes a connecting ring fixedly connected to the inner wall of the pipe opening, and a spring is connected to the connecting ring.

[0010] As a further feature of this invention, both the frame and the splash plate are made of stainless steel.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] During transportation, the glass tube can be placed inside the frame first, the sealing element can be inserted into the tube opening and brought into contact with the elastic element, and then the fastening screw can be tightened until it contacts the other end of the glass tube. At this point, the glass tube is inserted into the protective sleeve, which can wrap and protect the glass tube to prevent damage from impacts. When installing and using the fire sprinkler head, the fastening screw can be unscrewed first, then the glass tube can be removed, then the protective sleeve can be removed from the fastening screw, and finally the glass tube can be reinstalled. The operation is relatively convenient, thus giving the fire sprinkler head better durability. Attached Figure Description

[0021] 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.

[0022] Please see Figure 1-7 As shown, a fire sprinkler head includes a frame 1, a deflector plate 2 at one end of the frame 1, and a connecting seat 3 at the other end, with a pipe opening 4 on the connecting seat 3. Both the frame 1 and the deflector plate 2 are made of stainless steel, which has high strength and hardness, is not easily corroded, and is durable. A glass tube 5 is installed inside the frame 1, and an elastic element is installed inside the pipe opening 4. A sealing element 6, made of rubber, is installed on the glass tube 5 for insertion into the pipe opening 4 and contacting the elastic element. A threaded sleeve 7 is located at the center of the deflector plate 2, and a fastening screw 8 is threadedly connected inside the threaded sleeve 7. A protective rubber sleeve 9 is detachably installed on the fastening screw 8, used to wrap the glass tube 5. The protective rubber sleeve 9 is made of rubber and has good elasticity. Therefore, during the transportation of the fire sprinkler head, the glass tube 5 can be placed inside the frame 1 first, and the sealing element 6 can be inserted into the pipe opening 4 and contacting the elastic element. Then, tighten the fastening screw 8 until it contacts the other end of the glass tube 5. At this point, the glass tube 5 is inserted into the protective sleeve 9, which can wrap and protect the glass tube 5 to prevent it from being damaged by impact. When installing and using the fire sprinkler, the fastening screw 8 can be unscrewed first, then the glass tube 5 can be removed, then the protective sleeve 9 can be removed from the fastening screw 8, and finally the glass tube 5 can be reinstalled. The operation is relatively convenient, which makes the fire sprinkler more durable. The elastic element includes a connecting ring 15 fixedly connected to the inner wall of the pipe opening 4, and a spring 16 is connected to the connecting ring 15. When the sealing element 6 is inserted into the pipe opening 4, it will be squeezed with the spring 16, causing the spring 16 to compress and deform. The spring 16 will then exert a thrust on the glass tube 5 due to the deformation, pushing it towards the fastening screw 8, thus making the installation of the glass tube 5 more secure.

[0023] Please see Figure 2-5As shown, a through hole 10 is provided at the bottom of the protective sleeve 9, and a support plate 11 is provided on the fastening screw 8. The support plate 11 is used to pass through the through hole 10 and be inserted into the protective sleeve 9. The diameter of the through hole 10 is smaller than the diameter of the support plate 11. By passing the support plate 11 through the through hole 10 and inserting it into the protective sleeve 9, the protective sleeve 9 can be installed on the fastening screw 8. By expanding the through hole 10 and then prying the support plate out of the through hole 10, the protective sleeve 9 can be removed. This design makes the installation and removal of the protective sleeve 9 relatively convenient. A groove 12 communicating with the pipe opening 4 is provided on the connecting seat 3. The end of the protective sleeve 9 away from the through hole 10 is used to be inserted into the groove 12. After the protective sleeve 9 wraps around the glass tube 5, the end of the protective sleeve 9 away from the through hole 10 can be used to fit into the groove 12. The groove 12 limits the installation of the protective sleeve 9 within the frame 1, making it more stable and less prone to slippage, thus ensuring the protection of the glass tube 5. A first magnetic block 13 is provided at the end of the protective sleeve 9 away from the rotating disk, and a second magnetic block 14 matching the first magnetic block 13 is provided inside the groove 12. After the protective sleeve 9 is fitted into the groove 12, the first magnetic block 13 and the second magnetic block 14 will attract each other. The mutual attraction between the first magnetic block 13 and the second magnetic block 14 can improve the secure fit of the protective sleeve 9 within the groove 12.
