The distribution box acts as the terminal equipment in the circuit system, and various circuit components will be installed on its upper end for circuit control. A large number of connecting wires are required for the installation and connection of circuit components. In order to ensure that the circuit collection in the distribution box and the wear between circuits can be minimized, a wire trough structure is generally set in it to comb the lines.

[0003] In view of this, Chinese Patent No. CN210669001U proposes a wire trough mechanism for a distribution box, in which a pad is placed on the wire harness, and then the third spiral rod is rotated to rotate and move downward on the third spiral sleeve, pushing the strap downward, and then the jacket at the bottom of the strap will be stuck on the baffle, the strap will squeeze the pad, so that the pad fixes the wire harness to prevent the wire harness from shaking and being squeezed to cause damage to the wire harness. However, in the above technology, when combing the line connection wires in the wire trough, the operation steps are cumbersome, and there are many parts on the upper end of the structure. Long-term use can easily cause the parts to loosen, and maintenance is also very troublesome, thereby reducing the convenience of using the device. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model proposes a wire trough mechanism for a distribution box, comprising a distribution box back plate, wherein a cover plate type wire trough mechanism is arranged at the upper end of the distribution box back plate;

[0006] The cover-type wire trough mechanism includes a base plate fixed on one side of the back plate of the distribution box, first connecting grooves are opened at both ends of one side of the base plate, connecting rods are rotatably provided on the inner walls of the two first connecting grooves, and a protective cover plate is provided at one end of the two connecting rods. A plurality of first arc-shaped wire troughs are opened at equal distances on one side of the base plate, and an insulating bandage is fixed at one end of the inner wall of each of the first arc-shaped wire troughs, oblique grooves are opened at both ends of one side of the base plate, a plurality of second arc-shaped wire troughs are opened at equal distances on one side of the protective cover plate, and oblique blocks are fixed at both ends of one side of the protective cover plate.

[0007] In one example, the outer walls of the two inclined blocks are respectively connected with the inner walls of the two inclined grooves, and second connecting grooves are opened in the middle position of both ends of one side of the protective cover plate, and the outer walls of one end of the two connecting rods are respectively rotatably connected with the inner walls of the two second connecting grooves.

[0008] In one example, a plurality of heat dissipation holes are formed at equal distances on the other side of the protective cover plate, and the inner wall of each second arc-shaped wire groove is respectively connected to the inner walls of a plurality of the heat dissipation holes.

[0010] In one example, a plurality of heat dissipation slots are provided at equal distances on both ends of the bottom plate on one side of the back plate of the distribution box.

[0011] In one example, mounting blocks are fixedly provided at four corners of one side of the back plate of the distribution box, and screw holes are provided on one side of the four mounting blocks.

[0012] The wire trough mechanism for a distribution box proposed by the utility model can bring the following beneficial effects:

[0013] 1.

When the bottom plate and the protective cover plate are used to comb the line connection lines, the connection line parts inserted from both ends thereof pass through the limit brackets at both ends respectively and are guided by the rollers at the upper ends thereof, so that the surface wear of the connection lines is reduced and they are not easily damaged. The heat dissipation holes on one side of the protective cover plate and the heat dissipation grooves at both ends of the back plate of the distribution box are used to dissipate heat together to reduce the heat at the upper end thereof, so that the lines are not easily damaged due to heat, thereby improving the protection of the device.

When the base plate 2 and the protective cover plate 5 are in contact with each other, the oblique block 10 is just inserted therein and fits tightly with its inner wall.

[0025] The outer walls of the two inclined blocks 10 are respectively connected with the inner walls of the two inclined grooves 8, and the middle positions of the two ends of one side of the protective cover plate 5 are provided with second connecting grooves 11, and the outer walls of one end of the two connecting rods 4 are respectively connected with the inner walls of the two second connecting grooves 11, and when the bottom plate 2 is engaged with the protective cover plate 5, the two first connecting grooves 3 are just connected with the inner walls of the two second connecting grooves 11, so that the connecting rod 4 is stored therebetween without affecting the direct and close contact between the bottom plate 2 and the protective cover plate 5;

[0026] Furthermore, a plurality of heat dissipation holes 12 are formed at equal distances on the other side of the protective cover plate 5 , and the inner wall of each second arc-shaped wire groove 9 is respectively connected to the inner walls of a plurality of the heat dissipation holes 12 .

[0027] The two ends of one side of the back plate 1 of the distribution box are fixed with limit brackets 13, and the outer walls of the two limit brackets 13 are sleeved with rollers 14, and the two rollers 14 are rotatably connected to the outer walls of the two limit brackets 13, so that the connecting wires are guided at both ends of the bottom plate 2 to reduce the wear on the surface of the connecting wires, and prevent the long-term traction friction from causing the skin damage and leakage of the connecting wires;
