When the wires 12 are connected to other electrical components, if the length of the wires 12 is insufficient, the surplus can be released, which is more practical. Compared with the prior art, the present invention avoids the problem that traditional wiring racks usually adopt a fixed structure design, and their installation position and angle are determined at the initial installation stage, making it difficult to make large-scale adjustments later, through the setting of the adjustment mechanism.

[0055] In one embodiment of the present invention, see Figure 1-Figure 8 , the self-locking adjustment component comprises:

[0056] A support column 8 is fixedly mounted on the mounting plate 6, and a circular hole is provided at the bottom of the mounting box 7 for the support column 8 to pass through;

[0057] Limiting posts 18, the limiting posts 18 are fixedly installed in the installation box 7, and a plurality of limiting posts 18 are arranged at equal intervals in the circumferential direction of the installation box 7;

[0058] An adjustment plate 32 slidably mounted in the installation box 7, the adjustment plate 32 is fixedly connected to the support column 8, and a plurality of groups of limiting holes 19 for accommodating the limiting columns 18 are provided on the adjustment plate 32;

[0059] and a spring 20 for elastically pressing the adjustment plate 32, wherein the spring 20 is arranged in the installation box 7;

[0060] The inclination adjustment component comprises:

[0061] Support tubes 16, wherein the support tubes 16 are rotatably connected to the sliding seats 9 via support rotating tubes 13, and two groups of support tubes 16 are provided on each group of sliding seats 9;

[0062] An internally threaded tube 15, wherein the internally threaded tube 15 is rotatably mounted on a support tube 16, and a locking screw 17 for fixing the internally threaded tube 15 is also provided on the support tube 16; wherein an internally threaded hole threadedly connected to the locking screw 17 is provided on the side wall of the support tube 16, and the locking screw 17 can be moved by rotating the locking screw 17, so that the end of the locking screw 17 is pressed onto the internally threaded tube 15, thereby fixing the internally threaded tube 15 and preventing the internally threaded tube 15 from rotating without human drive;

[0063] and a threaded rod 14 threadedly connected to the internal threaded tube 15, wherein one end of the threaded rod 14 away from the internal threaded tube 15 is rotatably connected to the mounting plate 6 through a support rotating tube 13; wherein the support rotating tube 13 may be provided with multiple groups, wherein two groups of support rotating tubes 13 are rotatably mounted on both sides of the mounting plate 6, and two groups of support rotating tubes 13 are rotatably mounted on each group of sliding seats 9, so as to facilitate the installation of the threaded rod 14 and the support tube 16;

[0064] The sliding seat 9 is a U-shaped structure, and a plurality of strip-shaped protrusions are arranged inside the sliding seat 9 for slidingly cooperating with the strip-shaped grooves on the long rod; the strip-shaped protrusions are stuck in the strip-shaped grooves, which is beneficial to improve the stability of the connection between the sliding seat 9 and the wiring rack body 1, and at the same time makes the sliding seat 9 move more smoothly.

[0065] In this embodiment, when the horizontal angle of a single-group wiring rack body 1 needs to be adjusted after installation, the wiring rack body 1 can be pressed upward so that the inclination adjustment assembly can electrically move the mounting plate 6 upward, thereby enabling the support column 8 to push the adjustment plate 32 upward, and the spring 1 20 is compressed. At this time, the limiting hole 19 can be separated from the limiting column 18, so that the adjustment plate 32 can be rotated in the installation box 7 to adjust the horizontal angle of the wiring rack body 1. After the adjustment is completed, the wiring rack body 1 is released, and the spring 1 20 will push the adjustment plate 32 downward so that the limiting column 18 is reinserted into the limiting hole 19 to fix the adjustment plate 32. The more limiting columns 18 and limiting holes 19 there are, the wider the range of adjustable angles will be. If the wall will block the wiring rack body 1, it is only necessary to slide the wiring rack body 1 on the sliding seat 9 so that the sliding seat 9 moves to the end of the wiring rack body 1, so that the wiring rack body 1 can be rotated with the support column 8 as the axis to prevent wall obstruction.

[0066] By rotating the internally threaded tube 15, relative movement can be generated between the internally threaded tube 15 and the threaded rod 14, thereby changing the distance between the mounting plate 6 and the wiring rack body 1, thereby adjusting the inclination angle of the wiring rack body 1, allowing the wiring rack body 1 to transition to positions of different heights, and having a wider range of applications.

[0071] A support frame 22, wherein the support frame 22 is fixedly mounted on the support plate 4, and a guide rod 23 is also fixedly mounted in the support frame 22;

[0072] A support slider 25 rotatably connected to the support roller 21, wherein the support slider 25 is slidably mounted on the guide rod 23, and two groups of the support slider 25 are symmetrically arranged on the guide rod 23;

[0073] A spring 24 is sleeved on the guide rod 1 23, and the two ends of the spring 24 are respectively fixedly connected to two sets of supporting slide blocks 1 25;

[0074] A transmission gear 27, wherein the transmission gear 27 is rotatably mounted on the support frame 22;

[0075] and a rack 26 meshing with the transmission gear 27, wherein two groups of the racks 26 are slidably mounted on the support frame 22, and the two groups of racks 26 are fixedly connected to the two groups of support sliders 25 respectively;

[0076] The side surface of the support roller 21 is provided with an annular groove for placing the wire 12;

[0077] The cable support mechanism also includes an auxiliary limiting plate 2, which is detachably connected to the support plate 4 by screws; when in use, you can decide whether to use the auxiliary limiting plate 2. The auxiliary limiting plate 2 can block both sides of the support roller 21 by cooperating with the support plate 4, thereby further limiting the wires 12 passing between the two groups of support rollers 21, and further preventing the wires 12 from falling off;

[0078] The volume releasing mechanism comprises:

[0079] A reinforcing plate 10, wherein the reinforcing plate 10 is fixedly installed between the two sets of long rods;

[0080] A support frame 11, wherein at least one set of the support frame 11 is fixedly mounted on the reinforcing plate 10;

[0081] The second guide rods 28 are symmetrically arranged in two groups on the support frame 11, and the second support sliders 30 are slidably mounted on the two groups of the second guide rods 28;

[0082] A fixed plate 31 for placing the wires 12, wherein the fixed plate 31 is fixedly installed between the two sets of supporting slide blocks 30;

[0083] A pressing frame 5 for fixing the electric wires 12 passing through the fixing plate 31, wherein the pressing frame 5 is provided with multiple sets of fixing holes, and the fixing plate 31 is provided with strip holes 3; during installation, the pressing frame 5 can be fixed to the fixing plate 31 by bolts in combination with the strip holes 3 and the fixing holes, and the setting of the strip holes 3 can adjust the fixing position of the pressing frame 5, so as to facilitate the fixing of the electric wires 12;

[0084] And a spring three 29 for elastically supporting the supporting sliding block two 30 , wherein the spring three 29 is sleeved on the guide rod two 28 .

[0085] In this embodiment, when in use, the wire 12 can be passed through the release mechanism and the cable support mechanism in the manner shown in the wiring rack body 1 of the attached figure. When the length of the wire 12 is adjusted appropriately, the wire 12 is fixed to the fixed plate 31 by using the pressing frame 5, so that the wire 12 has a fixed point on each set of the wiring rack body 1. When the wire 12 passes through the two sets of support rollers 21 in an S-shaped trajectory, the traction force at both ends of the wire 12 and the gravity of the wire 12 itself will cause the two sets of support rollers 21 to generate opposite forces, so that the spring 24 is compressed, and at the same time, the Rongguo rack 26 and the transmission gear 27 are The coordinated setting can make the two groups of support rollers 21 approach each other. When the edges of the two groups of support rollers 21 touch, the wires 12 can be confined to the annular groove to prevent the wires 12 from falling off. At the same time, the rotating support rollers 21 can guide the wires 12. When the length of the wires 12 is not enough, pulling the wires 12 can make the fixed disk 31 press the spring three 29. When the fixed disk 31 moves downward, the straight-line distance between the fixed disk 31 and the support rollers 21 is shortened, so that the length of the wires 12 on the wiring rack body 1 that are stretched outward can be extended, making the installation more convenient.
