[0056] Example 1

[0057] <Wire passing device>

[0058] like Figures 1 to 4 As shown, this embodiment provides a wire-passing device for fixing a power line between two electrical devices that require linkage control; the two electrical devices are arranged side by side and spaced apart, one electrical device includes a first housing 31, and a first housing mounting structure 311 is formed on the side wall of the first housing 31; the other electrical device includes a second housing 41, and a second housing mounting structure 411 is formed on the side wall of the second housing 41; the wire-passing device includes a wire-passing box 1, and the wire-passing box 1 includes:

[0059] The first box body 11 includes a first wire-passing plate 111 and a first box body mounting structure 1121; the first wire-passing plate 111 is formed with a first wire-passing hole; the first box body mounting structure 1121 is arranged on one side of the first wire-passing plate 111 and away from the first wire-passing hole; the first box body mounting structure 1121 corresponds to and cooperates with the first housing mounting structure 311;

[0060] The second box body 12 is rotatably connected to the first box body 11 around a preset axis; the second box body 12 includes a second wire-passing plate 121 and a second box body mounting structure 1221; the second wire-passing plate 121 is arranged parallel to the first wire-passing plate 111 and is formed with a second wire-passing hole; the second box body mounting structure 1221 is arranged on one side of the second wire-passing plate 121 and away from the second wire-passing hole; both the second wire-passing hole and the first wire-passing hole can pass the power cord; the second box body mounting structure 1221 corresponds to and cooperates with the second shell mounting structure 411; the preset axis is perpendicular to both the first wire-passing plate 111 and the second wire-passing plate 121;

[0061] The first box body 11 and the second box body 12 are rotated relative to each other, so that the first box body 11 can be installed on the first housing 31 along a first installation direction, and the second box body 12 can be installed on the second housing 41 along a second installation direction;

[0062] Specifically, the first housing mounting structure 311 is a first mounting hole, and the second housing mounting structure 411 is a second mounting hole; the length direction of the first mounting hole is the first mounting direction, and the length direction of the second mounting hole is the second mounting direction. The first mounting direction and the second mounting direction may be the same or different;

[0063] A first box body limiting portion 112 is formed on the side of the first wire-passing plate body 111 away from the second wire-passing plate body 121, and the first box body limiting portion 112 protrudes from the plate surface of the first wire-passing plate body 111, and the first box body limiting portion 112 is formed with a first limiting groove, and the first limiting groove is the first box body mounting structure 1121; the first limiting groove extends along the width direction of the first wire-passing plate body 111; a second box body limiting portion 122 is formed on the side of the second wire-passing plate body 121 away from the first wire-passing plate body 111, and the second box body limiting portion 122 protrudes from the plate surface of the second wire-passing plate body 121, and the second box body limiting portion 122 is formed with a second limiting groove, and the second limiting groove is the second box body mounting structure 1221; the second limiting groove extends along the width direction of the second wire-passing plate body 121;

[0064] The first limiting groove cooperates with the hole wall of the first mounting hole to install the first box body 11 on the first shell 31 ; the second limiting groove cooperates with the hole wall of the second mounting hole to install the second box body 12 on the second shell 41 .

[0065] When the first installation direction is the same as the second installation direction, before installing the wire box 1, the first box body 11 and the second box body 12 are rotated and aligned and arranged side by side, and then, along the same installation direction, the first limiting groove is matched with the hole wall of the first installation hole, and the second limiting groove is matched with the hole wall of the second installation hole; when the first installation direction is different from the second installation direction, before installing the wire box 1, the first box body 11 and the second box body 12 are rotated and arranged to intersect, and then, along the first installation direction, the first limiting groove is matched with the hole wall of the first installation hole, and along the second installation direction, the second limiting groove is matched with the hole wall of the second installation hole;

[0066] The installation of the wire-passing box 1 is more flexible and can be applied to different first shell mounting structures 311 and second shell mounting structures 411, which expands the use scope of the wire-passing box 1 and meets different wire-passing requirements; the process of arranging the power lines is simple and convenient, the power lines are arranged regularly and not prone to errors, ensuring electrical safety, and solving the problem of complex and inconvenient power line arrangement in the prior art; the wire-passing device has a simple structure, occupies a small space, is easy to disassemble and assemble, and is simple to operate.

[0067] In order to solve the problem of complex rotation structure required when the first box body 11 and the second box body 12 are connected to each other in relative rotation, this embodiment proposes that the wire passing device further includes a rotating shaft assembly, which is arranged between the first box body 11 and the second box body 12; the rotating shaft assembly includes a first rotating shaft 21 and a second rotating shaft 22, and the first rotating shaft 21 and the second rotating shaft 22 are both hollow structures;

[0068] The first rotating shaft 21 is provided on the first box body 11 and communicates with the first wire hole; the second rotating shaft 22 is provided on the second box body 12 and communicates with the second wire hole; the power cord can be sequentially passed through the first wire hole, the first rotating shaft 21, the second rotating shaft 22, and the second wire hole;

[0069] The first rotating shaft 21 and the second rotating shaft 22 are coaxially arranged and rotatably matched together. The axis of the first rotating shaft 21 or the axis of the second rotating shaft 22 is a preset axis. When the first rotating shaft 21 and the second rotating shaft 22 rotate relative to each other, the first box body 11 and the second box body 12 can rotate relative to each other, and the positions of the first box body 11 and the second box body 12 can be flexibly adjusted to adapt to different shell installation structures.

[0070] Furthermore, the first rotating shaft 21 is sleeved on the outer circumference of the second rotating shaft 22. The inner side wall of the first rotating shaft 21 is formed with a first rotating shaft limiting portion 211 and a second rotating shaft limiting portion 212. The second rotating shaft limiting portion 212 is arranged adjacent to the first rotating shaft limiting portion 211. The outer side wall of the second rotating shaft 22 is formed with a third rotating shaft limiting portion 221.

[0071] When the first rotation shaft limiting portion 211 cooperates with the third rotation shaft limiting portion 221, the first rotation shaft 21 and the second rotation shaft 22 can rotate relative to each other;

[0072] When the second rotation shaft limiting portion 212 cooperates with the third rotation shaft limiting portion 221 , the first rotation shaft 21 and the second rotation shaft 22 can be relatively fixed.

[0073] Specifically, the first rotation shaft limiting portion 211 is an annular groove, and the second rotation shaft limiting portion 212 is an arc-shaped groove. The first rotation shaft limiting portion 211 and the second rotation shaft limiting portion 212 are both coaxially arranged with the first rotation shaft 21, and the first rotation shaft limiting portion 211 and the second rotation shaft limiting portion 212 are adjacently arranged along the axial direction of the first rotation shaft 21.

[0074] The third rotation shaft limiting portion 221 is an arc-shaped protrusion, and the third rotation shaft limiting portion 221 is coaxially arranged with the second rotation shaft 22; the structure of the arc-shaped protrusion is adapted to the structure of the arc-shaped groove.

[0075] To address the problems of instability when the first and second box bodies 11 and 12 rotate relative to each other and the lack of firmness when the first and second box bodies 11 and 12 are fixed relative to each other, this embodiment proposes that the inner side wall of the first rotating shaft 21 is formed with a plurality of annular grooves, and the plurality of annular grooves are sequentially spaced along the axial direction of the first rotating shaft 21; the inner side wall of the first rotating shaft 21 is formed with a plurality of arcuate groove groups, and the plurality of arcuate groove groups are sequentially spaced along the axial direction of the first rotating shaft 21, and the arcuate groove groups and the annular grooves are alternately arranged; each arcuate groove group includes a plurality of arcuate grooves, and the plurality of arcuate grooves are spaced along the circumference of the first rotating shaft 21;

[0076] The outer wall of the second rotating shaft 22 is formed with a plurality of arc-shaped protrusion groups, which are sequentially spaced apart along the axial direction of the second rotating shaft 22; each arc-shaped protrusion group includes a plurality of arc-shaped protrusions, which are spaced apart along the circumference of the second rotating shaft 22;

[0077] The annular grooves, the arc-shaped groove groups and the arc-shaped protrusion groups correspond one to one, and the arc-shaped grooves in the arc-shaped groove groups correspond one to one with the arc-shaped protrusions in the arc-shaped protrusion groups;

[0078] When the arc-shaped protrusions in the arc-shaped protrusion group are embedded in the corresponding annular grooves, the first rotating shaft 21 and the second rotating shaft 22 can rotate relative to each other;

[0079] When the arc-shaped protrusions in the arc-shaped protrusion group are embedded in the arc-shaped grooves in the corresponding arc-shaped groove group, the first rotating shaft 21 and the second rotating shaft 22 can be relatively fixed; when different arc-shaped protrusions in the arc-shaped protrusion group are embedded in different arc-shaped grooves in the corresponding arc-shaped groove group, the position between the first box body 11 and the second box body 12 can be adjusted, and then the installation method between the wire box 1 and the first shell 31 and the second shell 41 can be adjusted.

[0080] In this embodiment, three annular grooves are formed on the inner side wall of the first rotating shaft 21, and three arc groove groups are formed on the inner side wall of the first rotating shaft 21, each arc groove group includes four arc grooves; three arc protrusion groups are formed on the outer side wall of the second rotating shaft 22, and each arc protrusion group includes four arc protrusions.

[0081] In response to the problem that the arc-shaped protrusion does not fit firmly with the arc-shaped groove and the annular groove, this embodiment proposes that the outer diameter of the arc-shaped protrusion is larger than the inner diameter of the first rotating shaft 21, the outer diameter of the arc-shaped protrusion is smaller than the diameter of the annular groove and smaller than the diameter of the arc-shaped groove; the diameter of the annular groove is smaller than the diameter of the arc-shaped groove.

[0082] In order to solve the problem that the third rotation shaft limiting portion 221 is difficult to operate when it is matched with the first rotation shaft limiting portion 211 to match with the second rotation shaft limiting portion 212 along the axial direction of the first rotation shaft 21, this embodiment proposes that the second rotation shaft 22 or the third rotation shaft limiting portion 221 is made of a compressible material and has elasticity.
