[0021] Example

[0022] like Figure 1-Figure 4 As shown,

[0023] The utility model provides a power distribution cabinet. A power distribution cabinet comprises a threading device 1, a control button 2 is installed on the surface of the threading device 1, a plurality of safety doors 3 are provided on the front side of the threading device 1, a rainproof structure 4 is installed beside the safety door 3, a threading device 11 is provided inside the threading device 1, a bottom block 111 is provided inside the threading device 1, a plurality of large and small sleeve shafts 116 are nested at the upper end of the bottom block 111, a plurality of fixed shafts 114 are installed beside the large and small sleeve shafts 116, a spring 113 is placed on the outer ring of the fixed shaft 114, an upper movable plate 115 is connected above the spring 113, the upper end of the bottom block 111 is nested with the lower end of the fixed shaft 114, an irregular body 112 is placed beside the bottom block 111, the lower end of the spring 113 is connected to the upper end of the bottom block 111, and the inner side of the movable plate 115 is connected to the fixed shaft The outer sides of the threader 114 are penetrated, a fitting device 12 is installed on the upper left side of the threader 11, the tail end of the fitting device 12 is fixedly connected to the outer wall 14, the inner side of the outer wall 14 is fixedly connected to the mounting frame 13, the inner side of the threader 11 cooperates with the front end of the fitting device 12, a wire cavity 43 is opened in the rainproof structure 4, the wire cavity 43 is connected to the rainproof shell 41 outside, a plurality of external through holes 42 are opened inside the rainproof shell 41, the inner side of the outer wall 14 is fixedly connected to the outer side of the rainproof shell 41, a mounting plate 121 is opened in the fitting device 12, a threading port 122 is fixedly connected to the front end of the threading port 122, a guide port 123 is fixedly connected to the front end of the threading port 122, the outer side of the threading port 122 cooperates with the inner side of the threader 11, and the outer side of the mounting plate 121 is embedded with the inner side of the outer wall 14.

[0024] The position of the threading port 122 inside the adapter 12 and the position of the large and small sleeve shafts 116 are on the same horizontal plane, so that the wires can be more stable when passing through the large and small sleeve shafts 116 and the inside of the adapter 12.

[0025] When in use, the irregular body 112 is inserted between the hexagonal block of the fixed shaft 114 and the upper movable plate 115. During the rotation of the irregular body 112, its two outermost sides will have multiple different lengths, so that the user can adjust the distance between the upper movable plate 115 and the bottom block 111 as needed.

[0026] The horizontal position of the wire cavity 43 is consistent with the horizontal position of the wire threading opening 122 , so that the wire can be inserted into the outer through-hole 42 more quickly through the wire cavity 43 when extending outward from the wire threading opening 122 .

[0027] The large and small sleeve shafts 116 are of a structure in which a hollow large shaft is nested within a solid small shaft, so that the upper movable plate 115 can directly carry the large and small sleeve shafts 116 to move within the corresponding shaft when moving.

[0028] The working principle of the present invention is explained as follows: the various mechanical structures inside the distribution cabinet are all fixed by threads unless otherwise specified. In order to more intuitively observe the professional and technical features in the figure, the bolt connections are appropriately hidden. Before using the distribution cabinet, the user installs the required electrical devices in the mounting frame 13. The safety door 3 is used to protect the internal safety of the distribution cabinet. The user can control the internal structure of the distribution cabinet through the control button 2. When the electronic devices inside the distribution cabinet need to be connected to external devices, the user will classify the wires that need to be connected, and pass the classified wires through different sizes of sleeve shafts 116 to complete the classification of different wires. The maintenance personnel can also use this to quickly maintain the equipment inside the distribution cabinet.

[0029] After the wire passes through the fixed shaft 114 and the large and small sleeve shafts 116, the wire enters the threading port 122 along the guide port 123, and finally passes through the outer perforation 42 through the wire cavity 43, so that the distribution cabinet can be more stably connected to external devices. Since the rainproof shell 41 is in an inclined shape, the rainproof shell 41 can prevent rainwater from entering the distribution cabinet. The wire will inevitably move up and down during the process of passing through the threader 11. At this time, the wire moving upward will allow the upper movable plate 115 to be buffered by the spring 113. Impact buffering is performed. When the wire passes through the wire threader 11 and the installation is completed, the user picks up the irregular body 112 and puts the irregular body 112 into the hexagonal lower end of the fixed shaft 114 and the lower end of the upper movable plate 115. At this time, the spring 113 will shrink. Rotating the irregular body 112 can change the shrinkage of the spring 113. The user rotates the irregular body 112 and selects the optimal distance between the two sides of the irregular body 112 to fix the wires in the upper movable plate 115 and the bottom block 111, which greatly improves the practicality of the distribution cabinet.

[0030] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0031] Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the utility model is limited by the appended claims rather than the above description, so it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the utility model.
