Technical Field

[0001] This invention relates to the field of marine technology, specifically to a mounting device for a marine ceiling light fixture. Background Technology

[0002] A ship is a man-made means of transportation that primarily operates in water. Civilian ships are generally called boats, military ships are called warships, and small boats are called vessels or dinghies; collectively, they are referred to as ships or dinghies. Internally, they mainly include interior space, supporting structures, and drainage structures, and have a propulsion system that utilizes external or internal energy sources. Their shape is generally a streamlined envelope that helps overcome fluid resistance. Materials used are constantly evolving with technological advancements; early materials included natural materials such as wood, bamboo, and hemp, while modern materials primarily include steel, aluminum, fiberglass, acrylic, and various composite materials.

[0003] In floating production facilities, marine engineering products, and civilian ship projects, explosion-proof battery-powered lighting fixtures are often installed on the ceilings of living quarters. Since these devices require pre-drilling holes in the ceiling to fix the fixtures, with the device face down and the back up, and because these battery-powered lighting fixtures typically weigh over ten kilograms, the ceiling cannot usually support such weight for extended periods. Therefore, external brackets are needed to secure the fixtures, requiring additional welding work on-site, which is difficult, time-consuming, and labor-intensive. Addressing the shortcomings of existing technology, this invention designs a shipboard ceiling lighting fixture fixing device. Summary of the Invention

[0004] This invention provides a ceiling light fixture fixing device for ships, which has the advantage of solving the problem that the ceiling cannot support light fixtures weighing more than 10 kilograms for a long time, and solves the problems mentioned in the background art.

[0005] This invention provides the following technical solution: a ship ceiling light fixture fixing device, comprising a fixing structure, two inspection port structures, and a fireproof and waterproof structure. The fixing structure includes a reinforced U-shaped frame, a fixing frame, and a light fixture body. Two first fastening bolts are threaded on both sides of the outer surface of the reinforced U-shaped frame, and the four first fastening bolts can be fixedly connected to the ceiling. Second fastening bolts are welded and installed on both sides of the top of the outer surface of the reinforced U-shaped frame. Long bolts are installed in the internal threads of the two second fastening bolts. Threaded rods are installed in the internal threads of the reinforced U-shaped frame. A rotating handle is fixedly installed on the top of the threaded rods, and a connecting plate is rotatably installed on the bottom of the threaded rods. Side rods are fixedly installed on both sides of the outer surface of the connecting plate. Collars are fixedly installed at the ends of the two side rods. The two collars are sleeved on the outer surface of the long bolts, and fixing nuts are threaded on the outer surfaces of the two long bolts.

[0006] As a preferred embodiment of the present invention, sleeve plates are fixedly installed on both sides of the outer surface of the fixed frame, and sleeve holes are opened inside the two sleeve plates, which can be movably connected with long bolts.

[0007] As a preferred embodiment of the present invention, the outer surface of the fixed frame is threaded with third fastening bolts on both sides, and the third fastening bolts on both sides can be fixedly connected to the lamp body.

[0008] As a preferred embodiment of the present invention, the two access ports include a fixing plate, and four first fixing screws are installed on the internal threads of the two fixing plates, which can be fixedly connected to the ceiling.

[0009] As a preferred embodiment of the present invention, hinge seats are fixedly installed on both sides of the outer surface of the two fixed plates, and a rotating rod is fixedly installed between the two sets of hinge seats.

[0010] As a preferred embodiment of the present invention, hinge rods are hinged to the outer surfaces of the two rotating rods, baffles are fixedly installed on the outer surfaces of the two hinge rods, and handles are fixedly installed on the outer surfaces of the two baffles.

[0011] As a preferred embodiment of the present invention, the fireproof and waterproof structure includes a sealing base, and the sealing base has a slot inside.

[0012] As a preferred embodiment of the present invention, the slot has four second fixing screws installed on its internal threads, and the four second fixing screws can be fixedly connected to the ceiling.

[0013] As a preferred embodiment of the present invention, a fireproof cover is inserted into the slot, and holes are provided on both sides of the outer surface of the fireproof cover.

[0014] As a preferred embodiment of the present invention, the outer surface of the sealing base is provided with insertion holes on both sides, and a fixing pin is inserted into the two insertion holes. The two fixing pins can be connected to the outer surface of the fireproof cover by a loose insertion.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This type of ship ceiling light fixture fixing device, through a fixing structure, when installing the light fixture body, uses a first fastening bolt to fix a reinforcing U-shaped frame inside the ceiling. Then, by rotating the rotating handle, the threaded rod is pushed downward to push the connecting plate. Due to the connection of the side rods, the two side collars can slide on the outer surface of the long bolts to determine the fixing position of the light fixture body. Then, the light fixture body is fixed inside the fixing frame by a third fastening bolt. Then, the bolts are inserted through the sleeve holes into the two side long bolts and pushed upward to abut against the collars. At this time, the bottom of the light fixture body is flush with the bottom of the ceiling. Then, the collars can be fixed by screwing two fixing nuts on the two long bolts, thus completing the fixing of the light fixture body. This structure can effectively solve the problem of the light fixture body weighing more than 10 kilograms, which the ceiling cannot usually bear for a long time by installing a reinforcing U-shaped frame inside the ceiling. 2. This type of ship ceiling light fixture fixing device, through the inspection port structure, after the main body of the light fixture is fixed, two fixing plates are fixed to both sides of the main body of the light fixture by the first fixing screw. The side grooves can be covered by the baffle. When it is necessary to inspect or disassemble the main body of the light fixture, by pulling down the handle, due to the hinge of the hinge rod and the rotating rod, the baffle can be folded down around the rotating rod, thereby exposing the side grooves on both sides. At this time, the crew can use tools to unscrew the fixing nuts on both sides from the long bolts. Then the fixing frame and the main body of the light fixture can be removed from the long bolts, thereby completing the quick disassembly and maintenance without the crew having to climb into the ceiling for disassembly and assembly. 3. This type of ship ceiling light fixture fixing device, through a fireproof and waterproof structure, after the main body of the light fixture is fixed, the sealing base is fixed to the outer surface of the reinforced U-shaped frame by the second fixing screw. Then, by inserting the fireproof cover into the slot and inserting the fixing pin into the hole, the fireproof cover can be fixed. This can make the grooved part of the ceiling fireproof and waterproof, ensuring the safety of the ceiling environment. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figure 1-8 A mounting device for a ship's ceiling light fixture includes a fixing structure 1, two inspection port structures 2, and a fireproof and waterproof structure 3. The fixing structure 1 includes a reinforcing U-shaped frame 101, a fixing frame 111, and a light fixture body 115. Two first fastening bolts 102 are threaded on both sides of the outer surface of the reinforcing U-shaped frame 101, and the four first fastening bolts 102 can be fixedly connected to the ceiling. Second fastening bolts 103 are welded to the top two sides of the outer surface of the reinforcing U-shaped frame 101. Long bolts 104 are installed in the internal threads of the two second fastening bolts 103. Threaded rods 105 are installed in the internal threads of the reinforcing U-shaped frame 101. A rotating handle 106 is fixedly installed on the top of the threaded rods 105. A connecting plate 107 is rotatably installed on the bottom of the threaded rods 105. Side rods 108 are fixedly installed on both sides of the outer surface of the connecting plate 107. Collars 109 are fixedly installed at the ends of the two side rods 108. The two collars 109 are fitted onto the outer surface of the long bolts 104. Fixing nuts 110 are threaded on the outer surface of the two long bolts 104.

[0020] Please see Figures 4-6 The outer surface of the fixed frame 111 is fixedly mounted with sleeve plates 112 on both sides. The two sleeve plates 112 have sleeve holes 113 inside, which can be movably connected with long bolts 104. The outer surface of the fixed frame 111 is threaded with third fastening bolts 114 on both sides, which can be fixedly connected to the lamp body 115.

[0021] The lamp body 115 is fixed inside the fixing frame 111 by the third fastening bolt 114. Then, the long bolts 104 on both sides are inserted through the sleeve hole 113 and pushed upward to abut against the collar 109. At this time, the bottom of the lamp body 115 is flush with the bottom of the ceiling. Then, the collar 109 is fixed by screwing two fixing nuts 110 on the two long bolts 104, thus completing the fixing of the lamp body 115.

[0022] Please see Figure 7 The two access structures 2 include fixed plates 21, with four first fixing screws 22 threaded inside the two fixed plates 21, which can be fixedly connected to the ceiling. Hinges 23 are fixedly installed on both sides of the outer surface of the two fixed plates 21, and rotating rods 24 are fixedly installed between the two sets of hinges 23. Hinges 25 are hingedly installed on the outer surface of the two rotating rods 24, baffles 26 are fixedly installed on the outer surface of the two hinges 25, and handles 27 are fixedly installed on the outer surface of the two baffles 26.

[0023] When the main body of the lamp 115 needs to be inspected or disassembled, by pulling down the handle 27, the baffle 26 can be folded down around the rotating rod 24 due to the hinge of the hinge rod 25 and the rotating rod 24, thereby exposing the side slots on both sides. At this time, the crew can use tools to unscrew the fixing nuts 110 on both sides from the long bolt 104. Then the fixing frame 111 and the main body of the lamp 115 can be removed from the long bolt 104, thus completing the quick disassembly and inspection without the crew having to climb into the ceiling to disassemble and reassemble.

[0024] Please see Figure 8 The fireproof and waterproof structure 3 includes a sealing base 31, with a slot 32 inside the sealing base 31. Four second fixing screws 33 are threaded inside the slot 32 and can be fixedly connected to the ceiling. A fireproof cover 36 is inserted into the slot 32, and holes are formed on both sides of the outer surface of the fireproof cover 36. Insertion holes 34 are formed on both sides of the outer surface of the sealing base 31, and fixing pins 35 are inserted into two of the insertion holes 34, which can be connected to the loose insertion points on the outer surface of the fireproof cover 36.

[0025] After the main body 115 of the lamp is fixed, the sealing base 31 is fixedly fitted onto the outer surface of the reinforcing U-shaped frame 101 by the second fixing screw 33. Then, the fireproof cover 36 is fixed by inserting it into the slot 32 and the fixing pin 35 is inserted into the socket 34. This can make the grooved part of the ceiling fireproof and waterproof, and ensure the safety of the ceiling environment.

[0026] Working principle: When using a shipboard ceiling light fixture fixing device, firstly, a mounting groove is opened in the ceiling, and side grooves are opened on both sides of the mounting groove. At this time, the main body 115 of the light fixture can be installed. The main body 115 of the light fixture is fixed inside the fixing frame 111 by the third fastening bolt 114. Then, the reinforcing U-shaped frame 101 is fixed inside the ceiling by the first fastening bolt 102. Subsequently, by rotating the rotating handle 106, the threaded rod 105 is pushed downwards to the connecting plate 107. Due to the connection of the side rods 108, the... The two side collars 109 are slid on the outer surface of the long bolts 104 to determine the fixed position of the lamp body 115. Then, the lamp body 115 is fixed inside the fixing frame 111 by the third fastening bolt 114. Then, the bolts 104 are inserted through the sleeve holes 113 and pushed upward to abut the collars 109. At this time, the bottom of the lamp body 115 is flush with the bottom of the ceiling. Then, the collars 109 are fixed by screwing two fixing nuts 110 on the two long bolts 104, thus completing the installation of the lamp body. After the main body 115 is fixed, two fixing plates 21 are then fixed to both sides of the lamp body 115 by the first fixing screw 22. The side grooves can be covered by the baffle 26. When it is necessary to inspect or disassemble the lamp body 115, by pulling down the handle 27, due to the hinge of the hinge rod 25 and the rotating rod 24, the baffle 26 can be folded down around the rotating rod 24, thereby exposing the side grooves on both sides. At this time, the crew can use tools to unscrew the fixing nuts 110 on both sides from the long bolt 104, and then the fixing frame 111 can be removed. The main body 115 of the light fixture is removed from the long bolt 104, thus completing the quick disassembly and maintenance without the need for crew members to climb into the ceiling for disassembly and assembly. After the main body 115 of the light fixture is fixed, the sealing base 31 is fixed onto the outer surface of the reinforcing U-shaped frame 101 by the second fixing screw 33. Then, the fireproof cover 36 is fixed by inserting it into the slot 32 and the fixing pin 35 is inserted into the socket 34. This can make the grooved part of the ceiling fireproof and waterproof, ensuring the safety of the ceiling environment.
