[0034] Reference Figure 1 The modular light tube of this utility model embodiment includes a splicing component 1 and a lamp body 2. Multiple splicing components 1 are provided, and the two ends of the lamp body 2 are respectively inserted into two relatively independent splicing components 1. Referring to… Figure 2 The splicing component 1 includes a sleeve 100 and a rotating shaft 200. Multiple sleeves 100 are provided. One end of the sleeve 100 is provided with a connecting part 110 and the other end is provided with a sleeve hole 120. A rotating hole 130 is provided through the middle of the connecting part 110. One end of the rotating shaft 200 is provided with a plug 210 and the other end is detachably connected with a locking member 220. The rotating shaft 200 can be inserted into the rotating hole 130 and rotatably connected with the connecting part 110. The multiple connecting parts 110 can be stacked so that the multiple rotating holes 130 are in corresponding positions. The rotating shaft 200 passes through the multiple rotating holes 130. The plug 210 and the locking member 220 respectively abut against the surfaces of the two connecting parts 110 at both ends.

[0035] In practical use, two adjacent lamp bodies 2 are combined by splicing parts 1, so that multiple splicing parts 1 and multiple lamp bodies 2 are spliced ​​together. In the splicing parts 1 that connect two adjacent lamp bodies 2, two sleeves 100 are connected by a rotating shaft 200. The angle between the two sleeves 100 can be adjusted by the rotational engagement between the connecting part 110 and the rotating shaft 200. Specifically, when the two connecting parts 110 are stacked, the independent rotation of multiple sleeves 100 can be achieved by inserting the rotating shaft 200 into multiple rotating holes 130 at corresponding positions. Through the above technical solution, the combination of lamp tubes of different shapes can be achieved without multiple mold openings, improving the adaptability of splicing parts 1 and reducing the overall cost.

[0036] Specifically, as a specific implementation method, refer to Figure 3 and Figure 4 The sleeve 100 includes a first sleeve 100A and a second sleeve 100B, and the connecting part 110 includes a first connecting part 110A and a second connecting part 110B. The first sleeve 100A is provided with the first connecting part 110A, and the second sleeve 100B is provided with the second connecting part 110B. The first connecting part 110A and the second connecting part 110B are stacked. The first connecting part 110A is placed on top of the second connecting part 110B, and a rotating shaft 200 passes through a rotating hole 130 to connect the first sleeve 100A and the second sleeve 100B, so as to realize the mutual rotation between the first sleeve 100A and the second sleeve 100B.

[0037] During rotation, after a single splice 1 rotates to a certain angle, its shape needs to be fixed and constrained. Accordingly, a plurality of positioning grooves 112A are provided on the side of the first connecting part 110A facing the second connecting part 110B. The plurality of positioning grooves 112A are equidistantly arranged around the rotation center of the first connecting part 110A. A plurality of positioning protrusions 112B are provided on the side of the second connecting part 110B facing the first connecting part 110A. The plurality of positioning protrusions 112B are equidistantly arranged around the rotation center of the second connecting part 110B. The positioning protrusions 112B can correspond one-to-one with the positioning grooves 112A, and the positioning protrusions 112B can be embedded in the positioning grooves 112A.

[0038] In practical use, when it is necessary to adjust the angle of the two sleeves 100, the rotating shaft 200 and the locking member 220 are loosened, causing the first connecting part 110A and the second connecting part 110B to separate, and the positioning protrusion 112B to disengage from the positioning groove 112A. The first sleeve 100A and the second sleeve 100B rotate relative to each other to adjust the angle. After adjusting to a certain angle, the locking member 220 and the rotating shaft 200 are then locked, so that the plug 210 and the locking member 220 abut against the first connecting part 110A and the second connecting part 110B respectively, while the positioning protrusion 112B is embedded in the positioning groove 112A, thereby achieving the adjustment of the angle between the first sleeve 100A and the second sleeve 100B. For the positioning of 100B, preferably, the included angle between the rotation centers of two adjacent positioning protrusions 112B and the second connecting part 110B is 30°. Correspondingly, the included angle between the rotation centers of two adjacent positioning grooves 112A and the first connecting part 110A is 30°. This allows the included angle between the two sleeves 100 to be a stable multiple of 30°, which is convenient for use. Specifically, a scale is also provided on the connecting part 110 of one of the sleeves 100. Correspondingly, a pointer is provided on the other sleeve 100 which is on the same plane as the connecting part 110. During the relative rotation of the two sleeves 100, the rotation angle can be intuitively controlled.

[0039] In some embodiments, a rotating groove 113A is provided on the side of the first connecting portion 110A facing the second connecting portion 110B, and the rotating groove 113A and the rotating hole 130 of the first connecting portion 110A are coaxial; an annular protrusion 113B is provided on the side of the second connecting portion 110B facing the first connecting portion 110A, and the protrusion 113B can be inserted into the rotating groove 113A and rotate with the rotating groove 113A. The rotational engagement between the protrusion 113B and the rotating groove 113A enables the first sleeve 100A and the second sleeve 100B to rotate with each other. Specifically, as a further optimization of this structure, a positioning groove 112A is provided at the bottom of the rotating groove 113A, and a positioning protrusion 112B is provided on the protrusion 113B.

[0040] It is worth mentioning that, referring to Figure 5 The connecting part 110 has a recessed side that forms a hollow part 114. A power connection hole 140 is provided on the end face of the sleeve hole 120, and the hollow part 114 and the power connection hole 140 are connected. When the connecting parts 110 are stacked, the hollow parts 114 of two adjacent connecting parts 110 are connected. The power connection hole 140 is used to insert the power connection module of the lamp body 2. Multiple lamp bodies 2 are electrically connected by embedding wires or the like inside the hollow part 114.

[0041] Furthermore, a pillar 131 is built into the center of the hollow part 114, and a rotating hole 130 penetrates the pillar 131 to isolate the rotating hole 130 from the hollow part 114.

[0042] Among them, reference Figure 6 The sleeve 100 and the connecting part 110 are detachably connected. Specifically, the connecting part 110 is provided with a through hole 101 on the side near the sleeve 100, and the through hole 101 communicates with the hollow part 114. The sleeve is provided with a sealing plate 102 on the side near the connecting part, and the sealing plate 102 is provided with an electrical connection hole 140. When the sleeve 100 and the connecting part 110 are connected, the electrical connection hole 140 and the through hole 101 are positioned to correspond, so that the electrical connection hole 140 and the hollow part 114 are connected.

[0043] In some embodiments, the rotating shaft 200 is a bolt, the plug 210 is a nut, the plug 210 is circular, and the locking member 220 is a nut. The locking member 220 can be sleeved on the rotating shaft 200 and threadedly connected to the rotating shaft 200. The locking member 220 moves along the axial direction of the bolt, causing the distance between the locking member 220 and the plug 210 to change, so as to clamp the first connecting part 110A and the second connecting part 110B, or to loosen the first connecting part 110A and the second connecting part 110B.

[0044] Preferably, the connecting portion 110 that abuts against the plug 210 is provided with a first groove 111A, the shape of the first groove 111A matches the shape of the plug 210, and the plug 210 is embedded in the first groove 111A; the connecting portion 110 that abuts against the locking member 220 is provided with a second groove 111B, the shape of the second groove 111B matches the shape of the locking member 220, and the locking member 220 is embedded in the second groove 111B.

[0045] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
