The commonly used installation methods of the marine ceiling lamp include top bracket fixing and side self-tapping screw fixing, the former is to weld a bracket in the ceiling first, and then fix the lamp to the bracket, and the latter is to fix a wooden frame along the lamp hole, and then fix the lamp to the wooden frame. Both the above two methods need to open the lamp interior, and need to add auxiliary parts (the bracket in method one and the wooden frame in method two), and the whole installation process is complex and tedious, and consumes a lot of manpower. In view of the defects of the above two methods, the industry has appeared a spring bayonet installation method similar to the installation of a civilian tube lamp, but the method has new problems. The ceiling lamp is subject to various requirements of the ship lamp, such as salt mist resistance, corrosion resistance, electromagnetic interference resistance, protection (IP) level and the like, and usually uses a lamp body made of full metal, and the lamp body is large in size and heavy in weight, so that in order to ensure firm installation, a large number of spring buckles or buckles with large spring force are used in the spring bayonet installation method, and at this time, a contradiction occurs: if the number of spring buckles is small or the spring force is small, the installation, maintenance and disassembly are convenient, but the lamp installation is not firm enough, and there is a safety risk; if the number of spring buckles is large or the spring force is large, the lamp is fixed too firmly, but the installation, maintenance and disassembly are very difficult, and even when some cabin ceilings use composite materials, the ceiling is easily deformed or damaged during disassembly. In addition, relative to the service life of the lamp of at least ten years, the metal fatigue problem of the spring itself is also a hidden danger.

[0018] See Figs. 1 to 3 The utility model relates to a kind of fixing structure of ceiling lamp, including the ceiling 1 of cabin and the lamp body 2 of being fixed and installed with ceiling 1 by lamp body fixing assembly 3.The lamp body 2 is formed with the lower edge 21 of outwardly folding at bottom, the lamp body fixing assembly 3 is arranged on the outer side wall of lamp body 2 and is contained in the lamp hole 11 of ceiling 1 with lamp body 2, the lower edge 21 needs to be located below ceiling 1.To make way for lamp body fixing assembly 3, there needs to be a certain gap between the inner periphery of lamp hole 11 and the outer side wall of lamp body 2.The lamp body fixing assembly 3 is decided according to the size of lamp, usually, multiple lamp body fixing assembly 3 are distributed at the periphery of lamp body 2 to make lamp firm installation.

[0019] The lamp body fixing assembly 3 comprises a bracket 31, a stopper 32, a fixing bolt 33 and a non-coming-off nut 34. The bracket 31 comprises a first side plate 311, a second side plate 312, a bottom plate 313 and a top plate 314. The first side plate 311 is fixedly installed with the outer side wall of the lamp body 2, preferably by welding. The second side plate 312 is arranged perpendicularly to the first side plate 311 and vertically approaches the ceiling 1 from the side of the lamp body 2. The second side plate 312 can be formed by vertically bending a longitudinal side of the first side plate 311. When the lamp body fixing assembly 3 is located in the lamp hole 11 of the ceiling 1 with the lamp body 2, the bottom plate 313 is between the upper side of the lower edge 21 of the lamp body 2 and the lower side of the ceiling 1 and connects the bottom of the first side plate 311 and the second side plate 312, and the top plate 314 connects the top of the first side plate 311 and the second side plate 312. The fixing bolt 33 is sequentially threaded through the lower edge 21, the bottom plate 313 and the top plate 314 from bottom to top and is screwed with the non-coming-off nut 34. The lower edge 21 is also provided with a bolt clearance hole 211. To ensure that the stopper 32 can extend above the ceiling 1 and be installed in cooperation with the ceiling 1, the length of the stopper 32 should be greater than the distance between the outer side wall of the lamp body 2 and the inner wall of the lamp hole 11. A threaded hole 321 is formed at one end of the stopper 32 in the length direction, and the threaded hole 321 is threadedly connected with the non-coming-off nut 34 between the top plate 314 and the bottom plate 313. The other end of the stopper 32 in the length direction is formed with a pressing head 322 for cooperation with the ceiling 1. Preferably, the bottom of the stopper 32 is a flat surface, and the top is gradually inclined downward from the top of the threaded hole 321 to form the pressing head 322. A boss 323 is formed on the side of the stopper 32 towards the second side plate 312, which cooperates with the second side plate 312 to limit the stopper 32. When the boss 323 is rotated and kept against the second side plate 312 by screwing the fixing bolt 33, the stopper 32 gradually descends by further screwing the fixing bolt 33 upward until the lower edge 21 is attached to the lower surface of the ceiling 1 and the pressing head 322 is pressed against the upper surface of the ceiling 1, thereby achieving the fixed installation of the lamp body 2 and the ceiling 1.

[0020] The specific installation process of the lamp is described below. At the beginning of installation, the lamp body 2 is placed in the lamp hole 11 of the ceiling 1, and the first side plate 311 of the bracket 31 is fixedly installed with the outer side wall of the lamp body 2, preferably by welding. Fig. 2As shown, first use the cross screwdriver and other tools to tighten the fixed bolt 33 to the first side plate 311 side, the block 32 will slowly rise to the highest with the tool rotation direction, because the fixed bolt 33 tail has a anti-loose nut 34, so when the block 32 rises to the highest, the block 32 will keep close to the side wall of the lamp body 2. At this time, the lamp body 2 is put into the lamp hole 11 of the ceiling 1, the block 32 will not hinder the embedded installation of the lamp body fixing assembly 3. When starting to install, use the tool to tighten the fixed bolt 33 to the second side plate 312 direction, at this time the block 32 will slowly rotate and close to the ceiling 1, while closing, the block 32 rotates to the second side plate 312 with the tool rotation direction, the second side plate 312 and the boss 323 resist the block 32 to limit. At this time, continue to tighten the fixed bolt 33 upward to the second side plate 312, the block 32 keeps in the position and gradually descends until the lower edge 21 is close to the lower surface of the ceiling 1 while the pressure head 322 is pressed tightly on the upper surface of the ceiling 1, like Fig. 3 As shown, at this time, the firm installation of the lamp is completed. The whole installation process is simple and convenient, but can firmly install the lamp, and ensure the installation life.

[0021] After adopting the scheme, when the lamp is fixed to the ceiling 1, it does not need to install auxiliary parts in the ceiling 1, saves the installation cost, and does not need to open the inside of the lamp, saves the installation and disassembly time; at the same time, because there is no spring structure, the metal fatigue problem is also avoided, the installation life of the lamp is ensured, and thus the purpose of the application is achieved.
