Description

Technical Field

[0001] This utility model relates to the field of LED tube technology, specifically to a splicable and expandable LED tube. Background Technology

[0002] LED tubes are lighting products that use LEDs (light-emitting diodes) as their light source. They typically consist of multiple LED beads arranged either in a concentrated or dispersed manner within a tubular casing to provide illumination. LED tubes can replace traditional fluorescent tubes and are widely used in various occasions and applications.

[0003] Chinese patent CN 222849069 U discloses a splicable LED tube, including a lampshade. A first fixing buckle is provided on the outer surface of the lampshade, and a buckle core is welded to the inner surface of the first fixing buckle. A second fixing buckle is provided on the outer surface of the lampshade. Spring bases are installed on the inner surfaces of the slots, and springs are provided on the outer surfaces of the spring bases. A buckle and a push block are respectively installed on one side of the spring. A support frame is provided on the inner surface of the second fixing buckle, and the support frame is connected to the second fixing buckle via a bearing. A third fixing buckle is welded to the inner surface of the second fixing buckle. By setting the diameter of the first fixing buckle to be slightly larger than that of the second fixing buckle, the second fixing buckle can be fitted into the first fixing buckle. When the brightness is low, the buckle core inside the first fixing buckle inserts into the gap of the second fixing buckle. At this time, the buckle core presses against the third fixing buckle and the second fixing buckle. The bearing rotates, causing the second fixing buckle to rotate, thus the first fixing buckle can hold the second fixing buckle, forming a self-locking mechanism.

[0004] However, the above method cannot adjust the angle of the LED tubes during assembly. In some specific situations where it is necessary to install two adjacent LED tubes at a certain angle, it is inconvenient to fix the LED tubes, making the operation inconvenient. Utility Model Content

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0022] Please see Figures 1 to 4 This utility model provides a technical solution: a splicable and expandable LED tube, including: a lamp holder 1 and a lamp tube 2, the lamp tube 2 being an LED tube, the lamp tube 2 being installed on one side of the lamp holder 1 and electrically connected to the lamp holder 1, a plug being installed on one side of the lamp holder 1 via a wire, and electrically connected to an external power source via the plug, side frames 3 being provided at both ends of the lamp holder 1, a limiting groove 4 being provided at the outer end of the side frame 3, and a fixing groove 5 being provided on the outer side of both ends of the lamp holder 1, the lamp holder 1 being connected by a fixing component, the fixing component being used to movably connect two lamp holder 1 together to expand the LED tube.

[0023] The fixing components include a first connecting plate 6 and a second connecting plate 9, which are slidably connected. A side plate 10 is fixedly installed at one end of both the first connecting plate 6 and the second connecting plate 9. A limiting post 11 corresponding to the limiting groove 4 is fixedly installed on the middle side of the outer end of the side plate 10. A fixing block 12 corresponding to the fixing groove 5 is fixedly installed on the lower side of the outer end of the side plate 10. When the limiting post 11 is inserted into the limiting groove 4, the fixing block 12 is simultaneously inserted into the fixing groove 5 and fixed by screws. The fixing block 12 has a screw hole 13. One end of the screw passes through the screw hole 13 and is threaded to the inner wall of the fixing groove 5. The side plate 10 contacts the side frame 3, thereby fixing the side plate 10 to the outside of the side frame 3. By fixing the side plate 10 on one side of the first connecting plate 6 to one side of a lamp holder 1, and then fixing the side plate 10 on one side of the second connecting plate 9 to one side of another lamp holder 1, the two lamp holders 1 and the lamp tube 2 are spliced ​​together.

[0024] One end of the connecting plate 6 has a strip hole 8, and the other end of the connecting plate 6 has several limiting holes 7 evenly distributed. The strip hole 8 and the limiting holes 7 are located on the same horizontal line. A movable column 17 is fixedly installed on one side of the lower end of the connecting plate 9. The lower end of the movable column 17 slides through the strip hole 8 and is fixedly installed with a baffle 18. The diameter of the baffle 18 is larger than the width of the strip hole 8. By allowing the movable column 17 to slide in the strip hole 8, the connecting plate 9 slides on one side of the connecting plate 6, changing the distance between the two side plates 10, thereby changing the distance between the two lamp holders 1 and the lamp tube 2, which facilitates their installation.

[0025] A groove 14 is provided on the other side of the lower end of the connecting plate 2 9. A sliding column 15 is slidably inserted into the groove 14. A spring 16 is fixedly installed on the upper end of the sliding column 15. The upper end of the spring 16 is fixed to the inner wall of the bottom end of the groove 14. The sliding column 15 can slide in the groove 14 by compressing the spring 16. When the spring 16 is in a balanced state, one end of the sliding column 15 is located outside the groove 14. When the spring 16 is in a balanced state, the lower end of the sliding column 15 is inserted into the limiting hole 7, connecting the connecting plate 1 6 and... The connecting plate 29 is fixed in place. By inserting the sliding column 15 into different limiting holes 7, the distance between the two lamp tubes 2 can be adjusted. If it is necessary to splice the two lamp tubes 2 at a certain angle, push the sliding column 15 upward and into the sliding groove 14. The connecting plate 29 can then rotate around the upper end of the connecting plate 16 with the moving column 17 as the center, thereby realizing the rotation of the lamp holder 1 and the lamp tube 2. After adjusting the angle, the lamp holder 1 can be attracted to the part to be installed by the magnet at the rear end of the lamp holder 1.

[0026] When this device is in operation, if it is necessary to expand and splice the lamp tubes 2, the limiting post 11 is inserted into the limiting groove 4, and the fixing block 12 is simultaneously inserted into the fixing groove 5 and fixed with screws. The side plate 10 and the side frame 3 are in contact, thereby fixing the side plate 10 to the outside of the side frame 3. By fixing the two side plates 10 to one side of two adjacent lamp holders 1, the two lamp holders 1 can be spliced ​​together. Alternatively, the sliding post 15 can be pushed upward to enter the sliding groove 14, allowing the connecting plate 2 9 to rotate on the connecting plate 1 6, thereby adjusting the connection angle between the two lamp tubes 2.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
