[0027] Reference Figure 1-7 As shown, a curved arm assembly with built-in wires includes a first arm 1, a second arm 2, and a wire 3. Both the first arm 1 and the second arm 2 are provided with arm seats 4, and the hinge area of ​​the two arm seats 4 is provided with a cover 6. The cover 6 is provided with a fastener 7 and is fixed to at least one of the arm seats 4. At least one wire retainer 5 is provided in both the first arm 1 and the second arm 2.

[0028] like Figure 1As shown, the first arm 1 and the second arm 2 are rotatably connected together by a first arm seat 41 disposed on the first arm 1 and a second arm seat 42 disposed on the second arm 2. The lighting area on the curved arm assembly is disposed below the curved arm. The wire 3 is disposed at the hinge position of the first arm 1 and the second arm 2. The fastener 7 on the cover 6 is fixed to the first arm seat 41.

[0029] A recessed area 9 is provided at the hinge area of ​​the first arm seat 41 and the second arm seat 42. At the same time, a notch 91 is provided at the second through hole 421 on the second arm seat 42 opposite to the recessed area 9. The cover 6 covers the recessed area 9 and is fixed to the first arm seat 41 by the fastener 7. Meanwhile, a through groove 61 is provided on the cover 6, which is opposite to the first through hole 411. A boss 62 is provided in the through groove 61, the upper surface of which is higher than the horizontal plane of the recessed area 9. The purpose of the boss 62 is to prevent the first wire 31 from rubbing against the edge of the recessed area 9. The first wire 31 is placed on the surface of the boss 62 after passing through the first through hole 411, so that when the second arm 2 is rotating, the first wire 32 will not rub against the edge of the recessed area 9.

[0030] To ensure that the wire 3 is not exposed, such as Figure 4 As shown, a first through hole 411 and a second through hole 421 are respectively provided on the first arm seat 41 and the second arm seat 42. The wire 3 in the first arm 1 enters the hinge area through the first through hole 411 on the first arm seat 41 and enters the second arm 2 through the second through hole 421 on the second arm seat 42.

[0031] Meanwhile, the light strips in the first arm 1 and the second arm 2 need to be connected synchronously. The wire 3 includes a first wire 31 disposed in the first arm 1 and a second wire 32 disposed in the second arm 2. A first connector 311 is provided on the first wire 31, and a second connector 321 matching the first connector 311 is provided on the second wire 32. The installation positions of the first connector 311 and the second connector 321 are not limited, but preferably, the first connector 311 and the second connector 321 are installed in the second through hole 421. It is necessary to leave a portion of the excess first wire 31 at the hinge of the first arm 1 and the second arm 2. This arrangement is to prevent pulling when the articulated arm assembly moves.

[0032] like Figure 7As shown, a light groove 8 for installing a light strip is provided on the first arm 1 and the second arm 2. The light groove 8 includes a lampshade section 81 and a wire section 82. The light strip is fixed to the bottom of the light groove 8 by its own adhesive. The lampshade 83 is installed in the lampshade section 81, and the wire 3 is installed in the wire section 82. The wire retainer 5 is also installed here.

[0033] Specifically, within the conductor section 82, symmetrical steps 821 are provided on both sides, and an arc-shaped concave surface 811 is provided in the lampshade section 81. This is because the step 821 provides a more secure hold, and since the lampshade needs to be disassembled multiple times, the arc-shaped concave surface 811 makes it easier to fit.

[0034] The wire retainer 5 is assembled from a pressure block 51 and a threaded post 52. The pressure block 51 is U-shaped and consists of a main body 511 and stepped hook blocks 512 located on both sides of the main body 511. The connecting section between the main body 511 and the stepped hook blocks 512 is relatively thin, and the material of the pressure block 51 is plastic, which allows the stepped hook blocks 512 to deform on the main body 511. At the same time, a threaded hole 5111 is provided at the center of the surface of the main body 511. The threaded post 52 moves up and down on the main body 511 by being screwed into the threaded hole 5111. In order to ensure that the pressure block 51 will not come out of the lamp groove 8 when the threaded post 52 is pressing the wire 3, the minimum distance between the two stepped hook blocks 512 is less than the diameter of the threaded post 52.

[0035] The working process of this utility model is as follows: The first wire 31, the second wire 32, and the light strip are installed into the first arm 1 and the second arm 2. The first connector 311 of the first wire 31 passes through the first through hole 411 and is inserted into the second connector 321 installed in the second through hole 421. The wire retainer 5 is provided at both ends of the first arm 1 and at one end of the second arm 2 near the second arm seat 42. First, the pressure block 51 is embedded into the wire section 82 of the light groove 8. The step hook block 512 is pre-locked at the step 821. Then, the threaded post is... 52 is screwed into the threaded hole 5111 on the main body 511. The threaded post 52 expands the step hooks 512 at both ends so that they do not detach from the step 821. At the same time, the lower end of the threaded post 52 passes through the threaded hole 5111 and presses the first wire 31 and the second wire 32. Then, the lampshade 83 is fitted into the lampshade section 81 on the body through the arc-shaped concave surface 811. The cover 6 is covered at the hinge area of ​​the first arm seat 41 and the second arm seat 42 and fixed to the first arm seat 41 by the fastener 7.
