Background Art

[0002] As we all know, in order to increase the safety of ships, sprinklers need to be installed on the ceiling of the ship. When a fire or other danger occurs, the sprinklers spray water to extinguish the fire. However, the existing sprinklers cannot be fixed on the ceiling and need to be rigidly connected. The end of the pipe connected to the sprinkler needs to be welded to the ceiling through welding, which makes the construction difficult. Summary of the invention

[0003] The purpose of the present invention is to solve the above-mentioned deficiencies of the prior art and provide a marine nozzle fixing thread holder which has a simple structure, avoids secondary construction processing, reduces fire and gas operations, improves pipeline quality, and is convenient for nozzle installation.

[0004] The technical solution adopted by the present invention to solve the technical problem is: A marine nozzle fixing thread seat, characterized in that the fixing thread seat comprises a fixing pipe and a flange, the lower end outer wall of the fixing pipe is fixedly connected to the flange, the lower end inner wall of the fixing pipe is provided with an internal thread connected to the nozzle, the upper end outer wall of the fixing pipe is provided with an external thread connected to the connecting nut at the end of the hose, and the flange is provided with a connecting hole, and the connecting bolt passes through the connecting hole to be connected to the lower end surface of the ceiling.

[0005] The upper end of the spray head of the present invention is provided with an external thread matched with the internal thread of the lower end of the fixed pipe, and the spray head is fixedly connected with the internal thread of the fixed pipe via the external thread.

[0006] The connecting nut at the end of the hose of the present invention is fixedly connected to the hose, and the hose is fixedly connected to the outer wall of the fixed pipe through the connecting nut.

[0007] The fixing tube on the upper part of the ceiling described in the present invention is provided with a locking thread, a locking nut is sleeved on the outer wall of the locking thread, a locking plate is provided on the outer wall of the lower end of the locking nut, a locking hole is provided on the locking plate, and a locking bolt passes through the locking hole and is connected to the upper end surface of the ceiling.

[0008] The present invention has the advantages of simple structure, avoiding secondary processing during construction, reducing fire and gas operations, improving pipeline quality, and facilitating nozzle installation, etc. due to the adoption of the above structure.

[0012] The present invention is further described below in conjunction with the accompanying drawings: As shown in the accompanying drawings, a marine nozzle fixing thread holder is characterized in that the fixing thread holder comprises a fixing pipe 1 and a flange 2, wherein the lower end outer wall of the fixing pipe 1 is fixedly connected to the flange 2, the lower end inner wall of the fixing pipe 1 is provided with an internal thread connected to the nozzle 3, the upper end outer wall of the fixing pipe 1 is provided with an external thread connected to the connecting nut 5 at the end of the hose 4, the flange 2 is provided with a connecting hole 7, and the connecting bolt 6 passes through the connecting hole 7 and is connected to the lower end surface of the ceiling 8.

[0013] Furthermore, the upper end of the nozzle 3 is provided with an external thread 12 that matches the internal thread of the lower end of the fixed pipe 1 , and the nozzle 3 is fixedly connected to the internal thread of the fixed pipe 1 via the external thread 12 .

[0014] Furthermore, the connecting nut 5 at the end of the hose 4 is fixedly connected to the hose 4 , and the hose 4 is fixedly connected to the outer wall of the fixed pipe 1 through the connecting nut 5 .

[0015] Furthermore, a locking thread 13 is provided on the fixing tube 1 on the upper part of the ceiling 8, a locking nut 9 is sleeved on the outer wall of the locking thread 13, a locking plate 10 is provided on the outer wall of the lower end of the locking nut 9, a locking hole is provided on the locking plate 10, and a locking bolt 11 passes through the locking hole and is connected to the upper end surface of the ceiling 8.

[0016] When the present invention is in use, a fixing seat installation hole is pre-opened on the ceiling 8. During the installation process, the fixing pipe 1 of the fixing thread seat of the marine nozzle 3 is passed through the bottom of the ceiling 8, and the flange 2 is in contact with the lower end surface of the ceiling 8. Then, the connecting bolt 6 is passed through the connecting hole 7 of the flange 2 and fixedly connected to the ceiling 8. Then, the locking nut 9 and the locking plate 10 are sleeved on the top of the fixing pipe 1. The locking nut 9 is rotated through the locking thread 13 position until the locking plate 10 is locked and contacted with the upper end surface of the ceiling 8. Then, the locking bolt 11 is passed through the locking hole and connected to the upper end surface of the ceiling 8. Finally, the connecting nut 5 and the hose 4 are connected to the external thread 12 at the rear end of the fixing pipe 1, thereby realizing the fixed connection between the fixing thread seat of the marine nozzle 3 and the ceiling 8. Finally, the nozzle 3 is installed on the internal thread at the lower end of the fixing pipe 1 to realize the installation of the nozzle 3. Due to the adoption of the above structure, the present invention has the advantages of simple structure, avoiding secondary construction processing, reducing fire and gas operations, improving pipeline quality, and facilitating the installation of the nozzle 3.
