Description
Technical Field
[0001] This application relates to the field of lighting unit technology, and in particular to a disc-type LED lighting unit for subway use. Background Technology
[0002] In subway transportation systems, signal controllers play a crucial role in ensuring the safe and orderly operation of trains. As a core component of these signal controllers, the performance of the LED light source transformer directly affects the reliability and stability of the signal display. With the acceleration of global urbanization and the development of rail transit, subway construction projects are increasing. As a key piece of equipment in subway signaling systems, the LED light source transformer for signal controllers will need to meet higher usage requirements, and market demand continues to expand. Against this backdrop, the subway-specific LED lighting unit project has emerged. The LED lighting unit provides power to the signal controllers, and immediately cuts off the load and issues an alarm if the signal lights malfunction and go out. The LED lighting unit consists of a main body and a base. The main body includes a housing, which is bolted to the base. The main body contains multiple parts. After prolonged use, these parts may malfunction. However, the bolted mounting of the housing to the base makes disassembly of the main body inconvenient. Utility Model Content
[0003] The purpose of this utility model is to address the shortcomings and deficiencies of the existing technology by providing a disc-type LED lighting unit for subway use.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: The device includes a lighting unit body and a base. The lighting unit body is located on the base. The lighting unit body includes a housing. The housing has a fixing buckle on one side near the base and a driving buckle on the other side. The upper surface of the base has a first fixing hole and a second fixing hole. The fixing buckle is fastened in the first fixing hole and the driving buckle is fastened in the second fixing hole. The driving buckle can be disengaged from the second fixing hole under external force.
[0005] Preferably, the drive buckle is rotatably connected to the outer shell, a drive plate is provided on one side of the drive buckle, and a locking member is provided on the base, the locking member locking the drive plate to the base.
[0006] Preferably, the locking component includes a locking rod and a pressure cap. The side wall of the drive plate has a through hole. The locking rod is disposed on the base and is fixed inside the through hole. The pressure cap is sleeved on the upper end of the locking rod.
[0007] Preferably, the lower end of the outer shell is provided with a stabilizing post, which is inserted and fixed inside the side wall of the base.
[0008] Preferably, the lighting unit body further includes a wiring housing, one side of which is rotatably connected to the side wall of the outer casing.
[0009] Preferably, the outer side of the wiring housing is provided with a fixing plate, and the base is provided with a mating pressure plate, which is pressed against the fixing plate.
[0010] Preferably, the mating pressure plate slides on the base.
[0011] In summary, this application includes at least one of the following beneficial technical effects: 1. When it is necessary to remove the lighting unit body from the base, pull the pressure cap out of the locking rod, then the drive plate disengages from the locking rod, then the drive plate drives the drive buckle to rotate, then the drive buckle disengages from the second fixing hole, and finally the fixing buckle is pulled out from the first fixing hole, which facilitates the replacement of parts of the lighting unit body and improves the convenience of disassembling the lighting unit body. 2. When it is necessary to disassemble the terminal housing, the mating pressure plate can be driven to slide, so that the mating pressure plate and the fixed plate are misaligned. Then the terminal housing can be rotated on the outer shell, thereby exposing the parts inside the terminal housing, which facilitates the maintenance of the internal structure of the terminal housing.

[0014] The present invention will be further described below with reference to the accompanying drawings.
[0015] This application discloses a disc-type LED lighting unit for subway use.
[0016] Reference Figure 1 and Figure 2 The device includes a lighting unit body 1 and a base 2. The lighting unit body 1 is located on the base 2. The lighting unit body 1 includes a housing 3 and a wiring housing 4. The wiring housing 4 is rotatably connected to the side wall of the housing 3. The side wall of the housing 3 has a connecting hole. One side of the wiring housing 4 is connected to the housing 3 through the connecting hole.
[0017] Four stabilizing posts 15 are uniformly and integrally provided at the lower end of the outer casing 3. The stabilizing posts 15 are inserted and fixed inside the side wall of the base 2. When the outer casing 3 needs to be installed on the base 2, the four stabilizing posts 15 are inserted into the base 2 respectively, so that the outer casing 3 and the base 2 are pre-fixed.
[0018] Reference Figure 3 and Figure 4 A fixing buckle 5 is integrally provided on one side of the lower end of the housing, and a rotating groove 6 is provided on the other side of the lower end of the housing. A driving buckle 7 is rotatably connected in the rotating groove 6. The longitudinal section of the fixing buckle 5 and the driving buckle 7 is "L" shaped. The fixing buckle 5 and the driving buckle 7 are symmetrically arranged. A first fixing hole 8 and a second fixing hole 9 are provided on the side wall of the base 2. The lower end of the fixing buckle 5 is fastened and fixed in the first fixing hole 8, and the lower end of the driving buckle 7 is embedded and fixed in the second fixing hole 9.
[0019] A drive plate 10 is rotatably connected to the outside of the drive buckle 7. There are two locking parts 11 between the drive plate 10 and the base 2. The two locking parts 11 are symmetrically arranged. The locking part 11 includes a locking rod 12 and a pressure cap 13. One end of the locking rod 12 is fixed to the upper end face of the base 2. Two through holes 14 are opened on the side wall of the drive plate 10. The other end of the locking rod 12 passes through the through holes 14 and protrudes from the upper side wall of the drive plate 10. The pressure cap 13 is sleeved and fixed to the upper end of the locking rod 12. The pressure cap 13 can lock the drive plate 10 onto the base 2.
[0020] Reference Figure 5 A fixing plate 16 is integrally formed on the outer side of the wiring housing 4. A T-shaped groove 17 is formed on the upper end face of the base 2. A mating pressure plate 18 slides in the T-shaped groove 17. The longitudinal section of the mating pressure plate 18 is "L"-shaped, and the upper end of the mating pressure plate 18 presses on the fixing plate 16. Driving the mating pressure plate 18 to slide, so that the mating pressure plate 18 and the fixing plate 16 are offset from each other, the wiring housing 4 can then rotate on the outer shell 3, thereby exposing the parts inside the wiring housing 4, which facilitates the maintenance of the internal structure of the wiring housing 4.
[0021] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
