Description

Technical Field

[0001] This utility model relates to the field of building lighting technology, specifically a connection structure for a building lighting unit. Background Technology

[0002] The lighting design of industrial plant building units is a key link in ensuring production efficiency, visual comfort of personnel and safe production. The lighting method is mainly natural lighting and supplemented by artificial lighting, which is achieved by setting up skylights in a reasonable way. For plants with a large depth (such as more than 12 meters) or equipment in the middle that blocks the light, skylights are often used to supplement the internal lighting.

[0003] In existing technologies, skylights are generally used to increase the lighting area inside the factory. Since the machines in the factory need a low-dust environment to operate, drive components and screens are installed on the connection structure between the skylight and the building to prevent dust or insects from entering the factory when the light is being emitted.

[0004] Existing skylight screen components are generally flexible structures, which cause the screen to fold back and forth during the opening and closing of the window, increasing the risk of damage to the screen and shortening its lifespan. At the same time, the screens are all designed to let in light, and existing devices cannot quickly block sunlight when shading is needed. Machines in the factory are at risk of overheating due to prolonged exposure to sunlight. Therefore, a connection structure for building lighting units is proposed to address the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a connection structure for a building lighting unit to solve the problem of easy damage to the screens of existing building lighting units mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A connection structure for a building lighting unit includes an outer fixing cylinder, a drive assembly installed inside the outer fixing cylinder, and a screen assembly. The outer fixing cylinder has a sliding groove inside, and the sliding groove contains multiple limiting grooves. The screen assembly includes a fixing ring slidably connected to the inner side of the sliding groove. Multiple ball bearings, rotatably connected to the fixing ring, are embedded on the outer side of the fixing ring. The ball bearings are positioned inside the limiting grooves and are tightly fitted to them. The fixing ring has multiple vertically penetrating air holes inside. A composite mesh is fixedly connected to the top of the fixing ring, and a fixing frame is embedded inside the composite mesh. The drive assembly and the top of the composite mesh are both installed at the bottom of the building lighting unit.

[0008] Preferably, the composite mesh is provided with elastic rings fixedly connected to the top of the outer fixing cylinder on both the inner and outer sides, and the side of the elastic ring closest to the composite mesh is in contact with the composite mesh.

[0009] Preferably, a rainproof component is installed on the top of the outer fixing cylinder, and the rainproof component is located inside the building's daylighting unit.

[0010] Preferably, the rainproof component includes a rainproof ring, which is tapered, with the side of the rainproof ring having a smaller inner diameter facing upwards, and multiple fixing plates fixedly connected to the inner side of the rainproof ring.

[0011] Preferably, a storage slot is provided below the sliding groove and inside the outer fixed cylinder. A sunshade assembly is installed in the storage slot. The sunshade assembly includes a motor installed inside the outer fixed cylinder. An elastic rod is fixedly connected to the top of the motor output shaft. The end of the elastic rod away from the motor is slidably connected to the inside of the storage slot. A sunshade cloth is fixedly connected to the outside of the elastic rod. The side of the sunshade cloth away from the elastic rod is fixedly connected to the inside of the storage slot.

[0012] Preferably, the sunshade fabric has multiple elastic strips fixedly connected inside, and the two ends of the elastic strips are fixedly connected to an elastic rod and a storage groove, respectively.

[0013] Preferably, a reflector is provided inside the outer fixing cylinder.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In this utility model, through the setting of the screen window assembly, during the process of the composite screen rising, the fixing ring can slide inside the sliding groove, and the ball bearings on the outside of the fixing ring can roll in the limiting groove. The air hole on the fixing ring can balance the air pressure inside the sliding groove, making the movement of the fixing ring smoother. Since the composite screen is equipped with a fixing frame inside, the composite screen will not be folded during the movement of the screen window assembly. Therefore, the risk of damage to the screen window assembly is greatly reduced and the service life is significantly increased. This design can ensure the stability of the skylight assembly operation and ensure that the factory is in a low-dust environment.

[0016] 2. In this utility model, the rainproof component can play a role in preventing rain. When raindrops fall on the outside of the skylight, some raindrops will splash onto the rainproof ring. Due to the design of the rainproof ring being wider at the bottom and narrower at the top, the rainwater can flow to the outside along the rainproof ring without affecting the screen window component, thus effectively preventing the machines inside the factory from getting wet.

[0017] 3. In this utility model, the sunshade component can be set up so that when it is hot in summer, the motor can be started to make the elastic rod slide inside the storage groove. The sunshade cloth in the storage groove can block the inside of the outer fixing cylinder, so as to achieve the sunshade effect and prevent the machine in the factory from being exposed to the sun for a long time, which would cause the machine to overheat.

[0030] Please see Figure 1-8 This utility model provides a technical solution:

[0031] A connection structure for a building lighting unit includes an outer fixing cylinder 1, a driving assembly 2 installed inside the outer fixing cylinder 1, and a screen assembly 3. The outer fixing cylinder 1 has a sliding groove 11 inside, and multiple limiting grooves 12 are provided within the sliding groove 11. The screen assembly 3 includes a fixing ring 31 slidably connected to the inner side of the sliding groove 11. Multiple ball bearings 311 rotatably connected to the fixing ring 31 are embedded on the outer side of the fixing ring 31. The ball bearings 311 are located inside the limiting grooves 12 and are tightly fitted to them. Multiple vertically penetrating air holes 312 are provided inside the fixing ring 31. A composite mesh 32 is fixedly connected to the top of the fixing ring 31. The composite mesh 32 has a fixed frame 321 embedded inside. The drive assembly 2 and the top of the composite mesh 32 are both installed at the bottom of the building lighting unit. Through the screen assembly 3, during the upward movement of the composite mesh 32, the fixed ring 31 can slide inside the sliding groove 11, and the ball bearings 311 on the outside of the fixed ring 31 can roll in the limiting groove 12. The air hole 312 on the fixed ring 31 can balance the air pressure inside the sliding groove 11, making the fixed ring 31 move more smoothly. Since the composite mesh 32 has a fixed frame 321 inside, the composite mesh 32 will not be folded during the movement of the screen assembly 3. Therefore, the risk of damage to the screen assembly 3 is greatly reduced, and the service life is significantly increased.

[0032] The inner and outer sides of the composite mesh 32 are provided with elastic rings 5 ​​that are fixedly connected to the top of the outer fixing cylinder 1. The side of the elastic ring 5 closest to the composite mesh 32 fits against the composite mesh 32. This design can fill the gaps on the outside of the composite mesh 32 and prevent dust and insects from entering the gap between the composite mesh 32 and the outer fixing cylinder 1.

[0033] The top of the outer fixing cylinder 1 is equipped with a rainproof component 4, which is located inside the building's lighting unit. If the skylight is not closed during rainy weather, the rainproof component 4 can provide rain protection.

[0034] The rainproof component 4 includes a rainproof ring 41, which is tapered with the smaller inner diameter side facing upwards. Multiple fixing plates 42 are fixedly connected to the inner side of the rainproof ring 41. When rainwater drips onto the outside of the skylight, some raindrops will splash onto the rainproof ring 41. Due to the design of the rainproof ring 41, which is wider at the bottom and narrower at the top, rainwater can flow out along the rainproof ring 41 without affecting the screen component 3.

[0035] Below the sliding groove 11 is a storage groove 13 located inside the outer fixed cylinder 1. A sunshade assembly 6 is installed in the storage groove 13. The sunshade assembly 6 includes a motor 61 installed inside the outer fixed cylinder 1. An elastic rod 62 is fixedly connected to the top of the output shaft of the motor 61. The end of the elastic rod 62 away from the motor 61 is slidably connected to the inside of the storage groove 13. A sunshade cloth 63 is fixedly connected to the outside of the elastic rod 62. The side of the sunshade cloth 63 away from the elastic rod 62 is fixedly connected to the inside of the storage groove 13. When using the sunshade assembly 6, the motor 61 is started, causing the elastic rod 62 to slide inside the storage groove 13. The sunshade cloth 63 in the storage groove 13 can block the inside of the outer fixed cylinder 1, thus achieving a sunshade effect.

[0036] Multiple elastic strips 64 are fixedly connected inside the sunshade cloth 63. The two ends of the elastic strips 64 are fixedly connected to the elastic rod 62 and the storage groove 13, respectively. When sunshade is not needed, the motor 61 is started, the elastic rod 62 slides and bends inside the storage groove 13. At this time, the elastic strips 64 rebound and can pull the sunshade cloth 63 back into the storage groove 13, thereby preventing the sunshade cloth 63 from drooping and blocking the outer fixing cylinder 1.

[0037] The outer fixing cylinder 1 is equipped with a reflector 7. The design of the reflector 7 can reduce the absorption of light by the outer fixing cylinder 1, so that sunlight can pass through the outer fixing cylinder 1 and shine into the room smoothly.

[0038] Workflow: When ventilation is required by opening the sunroof, the drive assembly 2 on the outer fixing cylinder 1 is activated. The drive assembly 2 can drive the sunroof and composite screen 32 to rise. At this time, the fixing ring 31 can slide inside the sliding groove 11, and the ball bearings 311 on the outside of the fixing ring 31 can roll in the limiting groove 12. The air holes 312 on the fixing ring 31 can balance the air pressure inside the sliding groove 11, making the movement of the fixing ring 31 smoother. Since the composite screen 32 has a fixing frame 321 inside, during the movement of the screen assembly 3, the composite screen 3... 2. Since it cannot be folded, the risk of damage to the screen assembly 3 is greatly reduced, and its service life is significantly increased. This design ensures the stability of the skylight assembly's operation and maintains a low-dust environment in the factory. If the skylight is not closed during rainy weather, the rainproof assembly 4 can provide rain protection. Raindrops falling on the outside of the skylight will splash onto the rainproof ring 41. Due to the design of the rainproof ring 41, which is wider at the bottom and narrower at the top, rainwater can flow out along the rainproof ring 41 without affecting the screen assembly 3, thus effectively preventing rain from damaging the machinery inside the factory. When wet, the fixing plate 42 inside the rainproof ring 41 can provide stable support for the rainproof ring 41. During the use of the device, the elastic ring 5 on the outside of the composite mesh 32 can fit against the composite mesh 32. This design can fill the gaps on the outside of the composite mesh 32, preventing dust and insects from entering the gap between the composite mesh 32 and the outer fixing cylinder 1. When it is hot in summer, the sunshade component 6 can be used for sunshade. When using the sunshade component 6, the motor 61 is started, so that the elastic rod 62 slides inside the storage groove 13. The sunshade cloth 63 can block the inside of the outer fixing cylinder 1, thus achieving a sunshade effect and preventing the machines in the factory from being exposed to the sun for a long time, which would cause the machines to overheat. When the sunshade is not needed, the motor 61 is started, and the elastic rod 62 slides and bends inside the storage groove 13. At this time, the elastic pull strip 64 rebounds and pulls the sunshade cloth 63 back into the storage groove 13, thereby preventing the sunshade cloth 63 from drooping and blocking the outer fixing cylinder 1. The design of the reflector 7 can reduce the absorption of light by the outer fixing cylinder 1, so that sunlight can pass through the outer fixing cylinder 1 and shine into the room smoothly.
