Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a connection device for lighting fixtures. Background Technology

[0002] Work platform lights, also known as LED linear lights, are commonly used as lighting fixtures on the ceilings of maintenance workshops in subway depots and high-speed rail depots. Currently, the work platform lights used in these workshops are typically suspended from the ceiling using bolts and clips, with no other parts securing the lights except for the clips. Multiple work platform lights are arranged in a straight line along their length, forming a single work platform light group.

[0003] To meet illumination standards, workshop lighting typically involves installing multiple sets of work platform lights. To ensure these lights align in a straight line, current technology relies solely on adjusting the angle of individual lights using bolt holes on clips, visually aligning them along the length of the fixture without any connecting structures. However, in subway depots and high-speed rail maintenance workshops, the vibrations caused by subway and high-speed trains entering and exiting the workshop, coupled with the fact that the work platform lights are only suspended from the ceiling and lack any connecting structures, lead to displacement due to long-term vibration. This causes the lights to lose their straight line, affecting the workshop's aesthetics. Furthermore, relying solely on visual alignment during installation only results in a relatively straight line; under prolonged vibration, even slight displacement of a light can cause the entire work platform light line to bend. Utility Model Content

[0004] In view of this, and to solve the above problems, the purpose of this utility model is to provide a connection device for lamps, comprising:

[0005] The device comprises a rotating buckle, two side covers, two sealing rings, and two side plate assemblies. Each side cover has a through hole at one end, and each through hole has two locking blocks on its inner wall. The two locking blocks are arranged symmetrically about the center of the through hole. The two sealing rings are fitted onto the outer walls of both ends of the rotating buckle. The two ends of the rotating buckle are installed in the two through holes. Both ends of the rotating buckle can be operably engaged or disengaged from the corresponding two locking blocks. The two side plate assemblies are used to connect the two side covers and are installed on the two side walls of the two side covers.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0020] like Figure 1 As shown, a preferred embodiment of a connection device for a lighting fixture is illustrated, comprising:

[0021] The rotating buckle 1, two side covers 2, two sealing rings 3 and two side plate assemblies are provided. Each side cover 2 has a through hole 4 at one end. Each through hole 4 has two locking blocks 5 on its inner wall. The two locking blocks 5 are arranged symmetrically about the center of the through hole 4. The two sealing rings 3 are sleeved on the outer walls of both ends of the rotating buckle 1. The two ends of the rotating buckle 1 are installed in the two through holes 4. Both ends of the rotating buckle can be operably engaged or disengaged from the corresponding two locking blocks 5. The two side plate assemblies are used to connect the two side covers 2 and are installed on the two side walls of the two side covers 2.

[0022] Each side panel assembly includes a side panel body 6 and a hinge buckle 7. One end of the hinge buckle 7 is rotatably mounted on one end of the side panel body 6, and the other end of the hinge buckle 7 is rotatably mounted on the side wall of one side cover 2. The other end of the side panel body 6 is operably engaged or disengaged from the side wall of the other side cover 2.

[0023] In actual use, by rotating the buckle 1 and cooperating with the corresponding buckle 5, the two side covers 2 are connected and fixed. Then, one end of the side plate body 6 is rotated and installed on the side wall of one side cover 2 through the hinge buckle 7, and the other end of the side plate body 6 is fastened to the side wall of the other side cover 2, thus completing the installation of the rotating buckle 1, the two side covers 2 and the two side plate assembly.

[0024] Furthermore, as a preferred embodiment, each side panel body 6 has two parallel connecting plates 8 on one surface. The two connecting plates 8 are perpendicular to the side panel body 6. Each connecting plate 8 has a rotating hole 9 at one end. The hinge buckle 7 is rotatably installed in the two rotating holes 9 at one end. Each side panel body 6 has a main hook 10 at the other end. The main hook 10 can be operably engaged or disengaged from the side wall of the other side cover 2.

[0025] Furthermore, as a preferred embodiment, the hinge buckle 7 is arranged in a U-shape, and two hinge rods are formed on both sides of one end of the hinge buckle 7 in a mutually distant direction. The two hinge rods are rotatably installed in the two rotating holes 9.

[0026] Furthermore, as a preferred embodiment, each side cover 2 has a hinge seat 11 on one side wall, and each hinge seat 11 has a hinge groove 12 on one surface. The two ends of the hinge groove 12 pass through the two ends of the hinge seat 11. The other end of the hinge buckle 7 is rotatably installed in the hinge groove 12. Each side cover 2 has a pair of hooks 13 on the other side wall. Each main hook 10 can be operably engaged or disengaged from the corresponding pair of hooks 13. Furthermore, in actual use, firstly, the two sides of one end of the hinge buckle 7 are rotatably installed in the two rotating holes 9 of the two connecting plates 8, and then the other end of the hinge buckle 7 is rotatably installed in the hinge groove 12, so that one end of the side plate body 6 can rotate around the hinge seat 11. Then, the other end of the side plate body 6 is pressed, so that the main hook 10 of the other end of the side plate body 6 is engaged with the secondary hook 13 on the side wall of the side cover 2, thus completing the installation of the side plate body 6. Furthermore, a hinge seat 11 is provided on one side wall of the side cover 2, and a secondary hook 13 is provided on the other side wall of the side cover 2. When the two side covers 2 are connected by the rotating buckle 1, the two side plate bodies 6 are centrally symmetrically installed on the two side walls of the side cover 2 about the rotating buckle 1, thereby making the connection of the two side covers 2 more stable.

[0027] Furthermore, in a preferred embodiment, the rotating buckle 1 includes: an annular seat 14, a limiting ring 15, and two arc-shaped limiting plates 16. One end of the limiting ring 15 is installed at one end of the annular seat 14. The outer wall of the limiting ring 15 has two first slots 17, the length direction of which is arranged along the circumference of the annular seat 14. The two first slots 17 are centrally symmetrical about the center of the annular seat 14. The other end of the limiting ring 15 has two notches 18, which are connected to one end of the two first slots 17. The width of each first slot 17 gradually decreases from one end to the other end. The two first slots 17 engage or disengage with the corresponding two locking blocks 5. The two arc-shaped limiting plates... One end of each of the two arc-shaped limiting plates 16 is installed on the other end of the annular seat 14. Two second slots 19 are provided on the outer wall of the two arc-shaped limiting plates 16. The two second slots 19 are arranged along the circumference of the annular seat 14. The two second slots 19 are centrally symmetrical about the center of the annular seat 14. One end of the two second slots 19 passes through one side of the two arc-shaped limiting plates 16. The width of each second slot 19 gradually decreases from one end to the other end. The direction of the width change of the two second slots 19 is opposite to that of the two first slots 17. The two second slots 19 are engaged or disengaged from the corresponding two locking blocks 5. One sealing ring 3 is sleeved on the outer wall of the limiting ring 15, and the other sealing ring 3 is sleeved on the outer wall of the two arc-shaped limiting plates 16. Furthermore, in actual use, the side cover 2 is installed on two adjacent lamps. On one lamp, the two locking blocks 5 inside the through hole 4 of the side cover 2 slide from the notch 18 into the two first locking slots 17 of the limiting ring 15. Then, the lamp is rotated to lock it into the rotating buckle 1. Then, the two locking blocks 5 inside the through hole 4 of the side cover 2 on the other lamp slide from the gap 20 between the two arc-shaped limiting plates 16 into the two second locking slots 19. The lamp is then rotated. The two adjacent lamps rotate in opposite directions. In a vibrating environment, if the rotating buckle 1 rotates due to vibration, for example, if the rotating buckle 1 rotates clockwise, due to the width of the first locking slot 17 or the width of the second locking slot 19… The width of the first slot 17 must gradually decrease counterclockwise. Assuming that the width of the first slot 17 gradually decreases counterclockwise, rotating the buckle 1 clockwise will only make the buckle 1 more and more tightly connected to the lamp on one side. Moreover, since the length of the first slot 17 is limited, when the block 5 rotates to the end of the first slot 17, it will restrict the rotation of the buckle 1. When the buckle 1 rotates counterclockwise, the same principle applies. Therefore, no matter whether the buckle 1 rotates clockwise or counterclockwise, the buckle 1 and the side cover 2 will always be connected together, ensuring a stable connection between the lamps and thus limiting the lamps from shifting randomly during vibration, ensuring that all the work platform lamps are on the same straight line.

[0028] Furthermore, in a preferred embodiment, two spacer openings 20 are formed between the two arc-shaped limiting plates 16, and the two notches 18 are staggered with the two spacer openings 20. Further, the staggered arrangement of the two notches 18 and the two spacer openings 20, meaning they are not directly opposite each other, ensures that when the rotating buckle 1 is tightened with the locking block 5 in the through hole 4 of the side covers 2, the locking block 5 is located at the narrowest point of the first locking groove 17 or the second locking groove 19, thus securing it in place.

[0029] Furthermore, in a preferred embodiment, each through hole 4 includes a first channel portion 21 and a second channel portion 22 that are interconnected. The inner diameter of the first channel portion 21 is larger than the inner diameter of the second channel portion 22, and the locking block 5 is installed on the inner wall of the second channel portion 22.

[0030] Furthermore, in a preferred embodiment, the surface of each card block 5 facing the center of the through hole 4 is arc-shaped. This arc-shaped surface of the card block 5 ensures close contact between the surface of the card block 5 and the bottom inner wall of the first card slot 17 or the second card slot 19, preventing wobbling.

[0031] Furthermore, in a preferred embodiment, a sealing groove 23 is formed on the connecting surface of the first channel portion 21 and the second channel portion 22. The sealing groove 23 is arranged circumferentially along the through hole 4, and each sealing ring 3 is installed in a corresponding sealing groove 23. Furthermore, the cooperation between the sealing ring 3 and the sealing groove 23 improves the sealing performance and prevents dust from entering the lamp.

[0032] Furthermore, in a preferred embodiment, the outer diameter of the annular seat 14 is equal to the inner diameter of the first channel portion 21, and the outer diameters of the limiting ring 15 and the two arc-shaped limiting plates 16 are both equal to the inner diameter of the second channel portion 22. This improved sealing, preventing dust from entering the lamp fixture, and also prevented the outer diameters of the limiting ring 15 and the two arc-shaped limiting plates 16 from wobbling within the through hole 4, thus improving the stability of the lamp fixture connection.

[0033] Furthermore, in a preferred embodiment, the depth of the first channel portion 21 along its axial direction is equal to half the thickness of the annular seat 14 along its axial direction. Further, the fact that the depth of the first channel portion 21 along its axial direction is equal to half the thickness of the annular seat 14 along its axial direction ensures that the side covers 2 of adjacent lamps are in close contact, preventing dust from entering.

[0034] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
