Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a racetrack-style ceiling light. Background Technology

[0002] A good ceiling lighting system is essential for normal work and personnel activities. It is typically installed on the ceiling of a living space. However, existing ceiling light designs struggle to meet the growing demands, especially when quick disassembly and replacement are required. Traditional ceiling light designs have a fixed structure, consisting mainly of a bracket screwed to the ceiling, LED bulbs mounted on the bracket, and a lampshade clipped onto the bracket. Disassembling a traditional ceiling light requires prying out the lampshade, removing the LED bulbs, and finally unscrewing the bracket to replace the light. This process easily damages the embedded wire in the ceiling. Once the embedded wire is damaged, replacement requires adjusting the entire embedded part, resulting in significant maintenance costs and time. Therefore, a new ceiling light design is urgently needed to solve these problems. Utility Model Content

[0003] The purpose of this utility model is to provide a racetrack-style ceiling light to improve the efficiency of disassembly and assembly of existing ceiling lights.

[0004] To achieve the above objectives, this utility model provides a racetrack-style ceiling light, installed on an embedded iron in the ceiling of an activity space. It includes a fixed bracket with an overall racetrack-style structure and a top cover. The top cover is placed between the fixed bracket and the embedded iron, and the fixed bracket is connected and fixed to the embedded iron by a first countersunk bolt. A lighting fixture is arranged inside the fixed bracket, and several threaded grooves are provided on both sides of the fixed bracket. Spring pins are installed in the threaded grooves, and the spring pins are threadedly connected to the fixed bracket through the threaded grooves. The lighting fixture is detachably engaged with the fixed bracket through the spring pins.

[0005] The top covering pad is placed between the top of the activity space and the fixed bracket. On the one hand, it serves as protection to prevent damage to the top of the activity space from the fixed bracket. On the other hand, it enhances the appearance. In this practical technical solution, the fixed bracket is added and the spring pin is installed inside the fixed bracket. When facing the need for quick disassembly and assembly of lamps, the fixed bracket is retained, reducing the damage to the fixed bracket and embedded iron during the replacement process. The entire lighting fixture can be replaced directly, which significantly improves the efficiency of lamp disassembly and assembly.

[0006] The spring pin includes a pin rod and a fixing sleeve. The fixing sleeve is threaded and is installed in the fixing bracket through the thread. The pin rod passes through the fixing sleeve along the axial direction of the fixing sleeve, and the pin rod and the fixing sleeve are movably engaged.

[0007] The fixing sleeve is fixed inside the fixing bracket by the thread. The spring pin inside the fixing sleeve is movably engaged with the fixing sleeve. When it is necessary to fix the lighting fixture, the pin is used to limit and fix the lighting fixture, so that the lighting fixture can be fixed inside the fixing bracket. When it is necessary to disassemble, the pin is driven to move away from the fixing bracket, so that the pin can be disassembled from the lighting fixture, thereby completing the disassembly and assembly of the lighting fixture.

[0008] The fixed sleeve is further provided with a converging end, which cooperates with the pin rod to limit the axial displacement of the pin rod within the fixed sleeve.

[0009] The converging end is used to close one end of the fixing sleeve. The pin rod cooperates with the converging end to prevent the pin rod from detaching from the fixing sleeve. The inner diameter of the converging end is the same as the diameter of the rod body to guide the movement direction of the rod body.

[0010] The pin includes a rod body, a return spring, a connecting sleeve, and a limiting sleeve disposed outside the rod body. The limiting sleeve is movably engaged with the rod body and abuts against the converging end. The connecting sleeve is fixedly connected to the rod body. The return spring is disposed between the connecting sleeve and the limiting sleeve. Under normal conditions, the return spring drives the connecting sleeve to couple the rod body with the lighting lamp holder.

[0011] The limiting sleeve moves between itself and the rod body. The return spring cooperates with the limiting sleeve fixed between itself and the rod body, so that the limiting sleeve outside a part of the rod body is always in contact with the converging end, and the limiting sleeve outside another part of the rod body drives the rod body to maintain coupling with the lighting lamp holder.

[0012] The lighting fixture includes two parallel parts and two arc-shaped parts. The two parallel parts are arranged in parallel, and the two arc-shaped parts are arranged opposite each other on both sides of the two parallel parts. The two parallel parts and the two arc-shaped parts are joined together to form a racetrack-like structure and are placed in the fixed bracket.

[0013] The lighting fixtures form a racetrack-like structure, which allows light to cover the activity space more evenly, eliminates lighting dead spots, and provides a sufficient and uniform lighting environment for all work and personnel activities in the activity space.

[0014] The parallel section and the arc-shaped section both include a transition bracket and a top light holder. The transition bracket has a U-shaped cross-section, with its opening facing downwards and being embedded in the fixed bracket via a spring pin. The top light holder is installed in the opening of the transition bracket.

[0015] The transition bracket works in conjunction with the ceiling light holder. The transition bracket has a U-shaped cross-section. The transition bracket and the fixed bracket are detachably connected by the spring pin. When the light fixture needs to be replaced, the coupling between the spring pin and the fixed bracket can be adjusted to disassemble the transition bracket together with the lighting fixture.

[0016] The transition bracket has pin holes on both sides and a fixing hole at the top. The pin holes are elastically engaged with the spring pins, and the fixing hole is threadedly connected to the top light holder.

[0017] The pin hole is adapted to the rod body, and the fixing hole is used to install the top light holder, so that the top light holder is fixed in the transition bracket, and a gap is left between the transition bracket and the top light holder for the rod body to be installed.

[0018] The top light holder has a second countersunk bolt on its upper side. The end of the second countersunk bolt passes through the fixing hole and is fixed to the transition bracket by an external nut. The lower side of the top light holder is fitted with an elastically deformable cover. A light strip is glued to the top of the inner cavity of the top light holder.

[0019] The second countersunk bolt is used to connect and fix the top light holder to the transition bracket. The light strip is installed inside the top light holder so that the entire light strip can be fixed inside the top light holder.

[0020] The top light holder is provided with a fastening groove, which is opened on both sides of the inner wall of the top light holder and engages with the cover.

[0021] The fastening groove is used to fit the cover. The cover is elastically deformed and fitted into the fastening groove to provide a closed space for the light strip and reduce external interference to the light strip. The light strip can be controlled automatically or manually as needed. Because there are many existing technologies, they are not described in detail in this application.

[0022] This utility model discloses a racetrack-style ceiling light. Based on existing technology, it adds a fixed bracket that does not need to be replaced and improves the structure of the fixed bracket by adding a spring pin that can be elastically reset. After the spring pin is fixed in the fixed bracket, the lighting fixture is fixed in the fixed bracket by the action of the spring pin itself. This satisfies the need for quick assembly and disassembly of the ceiling light in the activity space without disassembling the fixed bracket, thus reducing damage to the embedded iron in the ceiling of the activity space.

[0030] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0031] Please see Figures 1 to 5This utility model provides a racetrack-style ceiling light, which is installed on an embedded iron 1 pre-embedded in the top of an activity space. It includes a fixed bracket 2 with an overall racetrack-style structure and a top cover 3. The top cover 3 is placed between the fixed bracket 2 and the embedded iron 1, and the fixed bracket 2 is connected and fixed to the embedded iron 1 by a first countersunk bolt 4. A lighting fixture 5 is arranged inside the fixed bracket 2. Several threaded grooves 6 are provided on both sides of the fixed bracket 2. Spring pins 7 are installed in the threaded grooves 6. The spring pins 7 are connected to the fixed bracket 2 by threads 13 through the threaded grooves 6. The lighting fixture 5 is detachably engaged with the fixed bracket 2 by the spring pins 7.

[0032] In this embodiment, the embedded iron 1 at the top of the activity space is used to fix the fixed bracket 2. The top cover 3 is placed between the embedded iron 1 and the fixed bracket 2 to reduce the damage of the fixed bracket 2 to the embedded iron 1. The structure of the fixed bracket 2 is improved. After the spring pin 7 is installed, the spring pin 7 can lock the lighting fixture 5. When it needs to be replaced, the locking of the lighting fixture 5 can be released by adjusting the spring pin 7, thereby improving the replacement efficiency of the lighting fixture 5.

[0033] Furthermore, the spring pin 7 includes a pin rod 11 and a fixing sleeve 12. The fixing sleeve 12 is externally threaded with a thread 13 and is installed in the fixing bracket 2 through the thread 13. The pin rod 11 passes through the fixing sleeve 12 along the axial direction of the fixing sleeve 12, and the pin rod 11 and the fixing sleeve 12 are movably engaged.

[0034] After the fixing sleeve 12 is fixed in the fixing bracket 2 by the external thread 13, the pin rod 11 is movably engaged with the fixing sleeve 12. The pin rod 11 uses the fixing sleeve 12 as an external constraint to fix the lighting lamp holder 5 in combination with its own elasticity.

[0035] Furthermore, the end of the fixed sleeve 12 is also provided with a converging end 14, which cooperates with the pin rod 11 to limit the axial displacement of the pin rod 11 within the fixed sleeve 12.

[0036] The inner diameter of the converging end 14 is the same as that of the pin rod 11, so as to guide the movement path of the pin rod 11 inside the fixing sleeve 12, so that the pin rod 11 aligns with the pin hole 213 on the lighting lamp holder 5, thereby fixing the lighting lamp holder 5.

[0037] Furthermore, the pin rod 11 includes a rod body 111, and also includes a return spring 112, a connecting sleeve 113, and a limiting sleeve 114 disposed outside the rod body 111. The limiting sleeve 114 is movably engaged with the rod body 111 and abuts against the converging end 14. The connecting sleeve 113 is fixedly connected to the rod body 111. The return spring 112 is disposed between the connecting sleeve 113 and the limiting sleeve 114. Under normal conditions, the return spring 112 drives the connecting sleeve 113 to couple the rod body 111 with the lighting lamp holder 5.

[0038] Under the action of the return spring 112, the rod 111 is inserted into the aligned pin hole 213 by the return spring 112 driving the connecting sleeve 113 to move, so that the lighting lamp holder 5 is coupled and fixed to the rod 111.

[0039] Furthermore, the lighting fixture 5 includes two parallel portions 21 and two arc-shaped portions 22. The two parallel portions 21 are arranged in parallel, and the two arc-shaped portions 22 are arranged opposite each other on both sides of the two parallel portions 21. The two parallel portions 21 and the two arc-shaped portions 22 are joined together to form a racetrack-like structure and are placed in the fixed bracket 2.

[0040] The arrangement of the two parallel portions 21 and the two arc-shaped portions 22 allows the lighting fixture 5 to be placed in the fixed bracket 2 of different shapes to adapt to the fixed bracket 2 of the racetrack-style structure.

[0041] Furthermore, both the parallel portion 21 and the arc-shaped portion 22 include a transition bracket 211 and a top light holder 212. The transition bracket 211 has a U-shaped cross-section, and its opening faces downward and is embedded in the fixed bracket 2 through the spring pin 7. The top light holder 212 is installed in the opening of the transition bracket 211.

[0042] The transition bracket 211 is used to fix the top light holder 212 on one hand, and cooperates with the rod 111 to fix the top light holder 212 on the other hand.

[0043] Furthermore, the transition bracket 211 has pin holes 213 on both sides and a fixing hole 214 on the top. The pin holes 213 are elastically engaged with the spring pin 7, and the fixing hole 214 is threaded 13 to the top lamp holder 212.

[0044] The pin hole 213 is used to align the rod 111, while the fixing hole 214 is used to fix the top lamp holder 212.

[0045] Furthermore, the upper side of the top lamp holder 212 is provided with a second countersunk bolt 215, the end of the second countersunk bolt 215 passes through the fixing hole 214 and is fixed to the transition bracket 211 by an external nut, the lower side of the top lamp holder 212 is fastened with an elastically deformable cover 216, and the top of the inner cavity of the top lamp holder 212 is bonded with a light strip 217.

[0046] The second countersunk bolt 215 is used to fix the top lamp holder 212 on the transition bracket 211, so that it is installed in the fixed bracket 2 along with the transition bracket 211 to complete the fixation. The cover 216 is used to provide a complete sealed space for the light strip 217 to reduce external influences.

[0047] Furthermore, the top light holder 212 is provided with a fastening groove 218, which is opened on both sides of the inner wall of the top light holder 212 and engages with the cover 216.

[0048] The fastening groove 218 is used to engage and fix the cover 216.

[0049] This utility model discloses a racetrack-style ceiling light. During installation, after the ceiling light base 212 is fixed on the transition bracket 211, it can be fixed to the fixed bracket 2 by means of the elastic pin. When disassembling, the elastic pin can be detached from the transition bracket 211 to complete the disassembly. This significantly improves the efficiency of disassembly and assembly of the light fixture, and there is no need to adjust the fixed bracket 2, reducing the impact of the fixed bracket 2 on the pre-embedded iron 1.

[0050] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
