DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0027] See Figures 1 to 5 The figure shows an adjustable angle three-tube lamp, comprising a lamp holder 1, plugs 2 fixed to the bottom of the lamp holder by screws at both ends. Three lamp tubes 3 are mounted on the bottom of the lamp holder, and a lamp plate 4 is fixed to the inner wall of each lamp tube. In this embodiment, the lamp holder is a metal structure, and the plugs are an insulating plastic structure. Because the lamp plate is fixed to the inner wall of the lamp tube, it can illuminate the lamp tube from any direction, and the illumination direction can be adjusted by rotating the lamp tube.

[0028] In actual application, the plug 2 includes an inner plug 21 and an outer plug 22 fixed on the inner plug, and the outer plug is provided with three mounting circular holes 23 on the same straight line; in this embodiment, the inner plug and the outer plug are fixed by buckles or screws, and can be set as needed.

[0029] In actual use, the end of the lamp tube is fixed with an end cap 5. Several snap-on lugs 6 are fixed to the side of the end cap facing away from the lamp tube. The outer surface of each snap-on lug is provided with a locking protrusion 7. During assembly, the end cap is attached to the surface of the outer plug and rotatably connected to the mounting hole via the snap-on lugs and the locking protrusions. The number of snap-on lugs is three or four, so the snap-on lugs can be rotated and adjusted within the mounting hole.

[0030] In actual use, semi-arc-shaped retaining grooves 8 are evenly distributed on the inner wall of the circular mounting hole. Several C-shaped tabs 9 are integrally formed on the outer side of the end cap, surrounding the snap-on lugs. During assembly, the snap-on lugs are rotatably connected within the circular mounting hole, and the arched surfaces of the C-shaped tabs abut against the semi-arc-shaped retaining grooves for retention. As the lamp rotates, the C-shaped tabs abut against the semi-arc-shaped retaining grooves for retention, ensuring stable and reliable positioning after rotation.

[0031] In actual use, the outer plug is also provided with an arcuate guide groove 10, located at the edge of the mounting hole and concentric with the mounting hole. A guide boss 11 is fixed to the side of the end cap; the guide boss is movable within the arcuate guide groove. Furthermore, the center angles of the two ends of the arcuate guide groove are 150-180 degrees. This structure allows the guide boss and arcuate guide groove to provide guidance and position control during rotation, meeting the angle adjustment requirements in insufficient situations and providing high practicality.

[0032] Furthermore, in actual application, a driving power source and a power supply line 12 connected to the driving power source are fixed in the plug; the driving power source is electrically connected to the light board via a wire, thereby achieving effectiveness and reliability of the electrical connection.

[0033] The utility model has positive effects: the structure of the utility model is reasonably arranged, there are three mounting circular holes on the outer plug of the plug, and end covers are provided at both ends of the lamp tube, and the end covers are rotatably connected to the mounting circular holes through snap-on ears and buckle protrusions, so that the three lamp tubes can be adjusted to different illumination angles as needed, which is beneficial to improving the lighting range, meeting the usage requirements of different situations, and facilitating the adjustment of the illumination angle. At the same time, it can also improve the stability and reliability of the installation, and has strong applicability and good practicality.

[0034] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components described in the specification can also be directly processed according to existing technical common sense without any doubt. At the same time, the connection method of each component adopts the mature conventional means in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so no specific description is given here.

[0035] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to enumerate all embodiments here. However, obvious variations or modifications arising from the essence of the present invention remain within the scope of protection of the present invention.
