A limiting groove 41 is provided on the support arm 2, and a snap-in jack 42 is provided in the limiting groove 41; a first elastic buckle 14 is provided on the outer wall of the insertion groove 12. After the insertion groove 12 is inserted into the insertion block 13, it is inserted into the limiting groove 41, and the first elastic buckle 14 is engaged with the snap-in jack 42. After the two arc lamp holders 11 are inserted and fitted together, the first elastic buckle 14 on the insertion groove 12 is snap-fitted with the snap-in jack 42 in the limiting groove 41 to connect the arc lamp holder 11 and the support arm 2 together. At the same time, the insertion block 13 in the insertion groove 12 is locked in the insertion groove 12. The limiting groove 41 limits the angle between the two arc lamp holders 11, making the structure of the assembled annular lamp holder 1 more stable and not easily deformed. The connection method between the above support arm 2 and the arc lamp holder 11 has a simple, ingenious structure, convenient assembly and low production cost.

[0036] See Figures 1 to 3 and Figure 9 and Figure 10 According to the above embodiments of the present invention, the lighting assembly includes a light strip (not shown in the figure) and a wire (not shown in the figure) connected to the light strip. A strip-shaped card slot 15 is provided on the arc lamp holder 11, and the light strip is arranged in the strip-shaped card slot 15. The light strip is fixed on the annular lamp holder 1 through the above structure, with a simple structure and convenient assembly. The opening of the strip-shaped card slot 15 is inclined towards the side of the installation dartboard 8. This makes the light of the light strip converge towards the dartboard 8, and the lighting effect is better.

[0037] See Figures 4 to 10 According to the above embodiments of the present invention, a wire passing hole 43 is provided on the limiting groove 41, and a wire clamping groove 44 is provided on the support arm 2. One end of the wire is connected to the light strip, and the other end of the wire passes through the wire passing hole 43 and is clamped in the wire clamping groove 44. The wire in the lighting assembly is strung from the annular lamp holder 1 to the support arm 2 through the above wire passing hole 43 and is clamped in the wire clamping groove 44 on the support arm 2, making the appearance of the present invention more neat and beautiful during use, and avoiding the interference or the risk of easy breakage caused by the floating of the wire during use.

[0038] See Figures 4 to 10, according to the above embodiments of the present invention, the support arm 2 includes a dartboard connecting foot 3 and a lamp holder connecting arm 4. The dartboard connecting foot 3 is hinged to the lamp holder connecting arm 4. One end of the lamp holder connecting arm 4 is hinged to the dartboard connecting foot 3, and the other end of the lamp holder connecting arm 4 is connected to the annular lamp holder 1. The limiting groove 41 is provided at the other end of the lamp holder connecting arm 4. The wire clamping groove 44 is provided on the lamp holder connecting arm 4. During specific use, the dartboard connecting foot 3 is fixedly connected to the dartboard 8 on which the shadowless lamp is to be installed. The process of installing the present invention on the dartboard 8 is as follows: after first fixedly connecting the dartboard connecting foot 3 to the dartboard 8, fold the lamp holder connecting arm 4 so that the lamp holder connecting arm 4 is close to the dartboard 8. Without the interference of the support arm 2, the dartboard protection ring 9 can be directly sleeved on the dartboard 8. By setting the support arm 2 as a foldable support arm, the installation process of the dartboard protection ring 9 is simplified, and the use process is very convenient.

[0039] See Figure 1 and Figures 4 to 10 , according to the above embodiments of the present invention, the dartboard connecting foot 3 includes a connecting plate 31 and a support plate 32. The plane where the connecting plate 31 is located is perpendicular to the plane where the support plate 32 is located, and the support plate 32 is hinged to the lamp holder connecting arm 4. Generally, when the dartboard 8 is hung on the wall for use, a dartboard protection ring 9 is sleeved outside the dartboard 8 to prevent the dart from hitting the wall directly when it misses, causing damage to the wall or the dart head. The installation of the dartboard protection ring 9 makes it so that when the dart misses, it generally hits the dartboard protection ring 9, neither causing damage to the wall nor to the dart head. When installing the present invention on the dartboard 8, the connecting plate 31 is located on the back of the dartboard 8 and is fixedly connected to the dartboard. The support plate 32 is close to the side wall of the dartboard 8. After the dartboard protection ring 9 is installed, the support plate 32 is located in the gap between the dartboard 8 and the dartboard protection ring 9. Therefore, the dartboard connecting foot 3 in the above structure does not affect the installation of the dartboard protection ring 9 during use, and the above dartboard connecting foot 3 has a simple structure, convenient assembly, firm fixation, and low production cost.

[0040] See Figures 4 to 11, according to the above embodiments of the present invention, it further includes a locking block 7. A locking groove 71 is provided on the locking block 7, and a second elastic buckle 35 is provided on the connecting plate 31. The second elastic buckle 35 cooperates with the locking groove 71. When installing the dartboard connecting foot 3 through the locking block 7, first fix the locking block 7 on the back of the dartboard 8 near the edge by screws, and then insert the second elastic buckle 35 into the locking groove 71 to engage with the locking groove 71 to fix the dartboard connecting foot 3 on the dartboard. The dartboard connecting foot 3 is assembled on the dartboard 8 in this way, and the disassembly and assembly are very convenient. Spare screw holes 36 are provided on both the connecting plate 31 and the support plate 32. After the dartboard 8 is used for a long time, the screws between the locking block 7 and the dartboard 8 may become disengaged, resulting in the loosening of the locking block 7, and the dartboard connecting foot 3 cannot be locked on the dartboard 8 continuously. The dartboard connecting foot 3 can be fixed on the dartboard 8 continuously by passing screws through the spare screw holes 36 on the connecting plate 31, thereby extending the service life of the dartboard 8.

[0041] See Figures 4 to 10 and Figure 12, according to the above embodiments of the present invention, the dart target connecting foot 3 is provided with a first hinge portion 33, and the lamp holder connecting arm 4 is provided with a second hinge portion 45. The first hinge portion 33 and the second hinge portion 45 are hinged together by a hinge shaft 6; a torsion spring 5 is provided between the first hinge portion 33 and the second hinge portion 45. The torsion spring 5 is provided with a first torsion arm 51 and a second torsion arm 52. The first torsion arm 51 abuts against the dart target connecting foot 3, and the second torsion arm 52 abuts against the lamp holder connecting arm 4; a clamping protrusion 34 is provided on the first hinge portion 33, and a clamping edge 46 is provided on the lamp holder connecting arm 4. The clamping protrusion 34 and the clamping edge 46 are in limiting cooperation. In the above structure, the setting of the torsion spring 5 can ensure that after the support arm 2 is installed on the dart target 8, the lamp holder connecting arm 4 and the dart target connecting foot 3 that are hinged together are always in an unfolded state when not affected by external forces, avoiding the folding of the hinge portion caused by the self-weight of the lamp holder connecting arm 4. The unfolded state of multiple support arms 2 facilitates the installation of the annular lamp holder 1. When it is necessary to fold the lamp holder connecting arm 4, push the lamp holder connecting arm 4 along the hinge shaft 6 towards the front end of the dart target 8. During this process, it is necessary to overcome the limiting resistance of the clamping protrusion 34 to the clamping edge 46. When the clamping edge 46 passes over the clamping protrusion 34, that is, the clamping edge 46 moves from one side of the clamping protrusion 34 to the other side, at this time, release the lamp holder connecting arm 4. Under the limiting resistance of the clamping protrusion 34 to the clamping edge 46, the lamp holder connecting arm 4 cannot be unfolded; when it is necessary to unfold the lamp holder connecting arm 4, only an external force is needed to pull the lamp holder connecting arm 4 outwards, overcome the resistance of the clamping protrusion 34 to the clamping edge 46, make the clamping edge 46 pass over the clamping protrusion 34 again, and then the lamp holder connecting arm 4 can be in an unfolded state under the action of the torsion spring 5. The above structure enables the user, when not using the shadowless lamp, in order to avoid snagging with the rest of the outside world, there is no need to remove it as a whole. Just remove the annular lamp holder 1, and then fold the lamp holder connecting arm 4. When using it again, just unfold the lamp holder connecting arm 4 and install the annular lamp holder 1, which has high flexibility. At the same time, the folded state of the lamp holder connecting arm 4 also facilitates the sleeving and fixing of the dart target protection ring 9.

[0042] See Figure 1 , Figure 9 and Figure 10 , according to the above embodiments of the present invention, the number of the arc lamp holders 11 is the same as the number of the support arms 22. Multiple arc lamp holders 11 in the present invention are connected end to end in sequence to form an annular lamp holder 1, so that the number of connection points in the annular lamp holder 1 is the same as the number of arc lamp holders 11. Therefore, the number of support arms 22 is the same as the number of the above connection points. In addition to being clamped and matched with the arc lamp holders 11, the support arms 22 also strengthen and fix the connection points between two adjacent arc lamp holders 11 and limit the angle after the two arc lamp holders 11 are connected, greatly improving the structural strength of the present invention and making it more stable and reliable during use.

[0043] SeeFigure 4 and Figure 6 According to the above embodiments of the present invention, the lamp holder connecting arm 4 is provided with an external fixing hole 47 or an external fixing groove. In this embodiment, it is preferably to provide an external fixing hole 47 on the lamp holder connecting arm 4. The provision of the external fixing hole 47 or the external fixing groove facilitates the installation of a mobile phone or other shooting device on the lamp holder connecting arm 4, which is convenient for the user to shoot the dart throwing process or the moment when the dart hits the dartboard 8.

[0044] The above is only the specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
