[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-4 , the present invention provides a technical solution: a distributed DTU device convenient for maintenance, including a terminal cabinet 1 and a DTU body 2. A wiring port is provided on the rear wall of the DTU body 2. A short shaft 2.1 is provided at the bottom of one side wall of the DTU body 2. A support plate 2.2 is fixed at a position corresponding to one side of the short shaft 2.1 in the middle of the top surface of the DTU body 2. A positioning bolt 2.3 is threadedly sleeved on the support plate 2.2.

[0024] At least two mutually parallel guide rails 3 are horizontally fixed at the top of one side wall of the inner cavity of the terminal cabinet 1.

[0025] A linear card slot 4.1 that is slidably clamped and matched with the guide rail 3 is provided on the outer side wall of the sliding substrate 4. Positioning screw holes 4.3 and shaft holes 4.2 are respectively provided at the top and bottom of the middle part of the inner side wall of the sliding substrate 4. The short shaft 2.1 is rotatably sleeved in the shaft hole 4.2, and the positioning bolt 2.3 is threadedly sleeved and matched with the positioning screw hole 4.3. A buckle plate 4.6 is provided at the front end of the middle part of the inner side wall of the sliding substrate 4.

[0026] The cable positioning member 5 is vertically arranged at the rear end of the inner side wall of the sliding base plate 4 and is used to arrange the cables vertically. The cable positioning member 5 includes a vertical plate 5.1 and a plurality of partitions 5.2 extending horizontally and arranged vertically and fixed to the side walls of the vertical plate 5.1. The top and bottom ends of the side walls of the partitions 5.2 are respectively provided with through-holes 5.1.1. The top and bottom ends of the inner side wall of the sliding base plate 4 are respectively provided with fixing screw holes 4.4 corresponding to the through-holes 5.1.1. The through-holes 5.1.1 are respectively provided with fixing bolts 5.3 threadedly connected to the fixing screw holes 4.4. The outer ends of the partitions 5.2 are respectively provided with slots 5.2.1 vertically, and the slots 5.2.1 are collectively inserted with slats 5.4. The top ends of the slats 5.4 are fixed with end plates 5.5, and the top surfaces of the end plates 5.5 are fixed with lifting caps 5.6. That is, multiple cables connected to the connection ports on the rear wall of the DTU are passed through the cavity between two adjacent partitions 5.2. After the strips 5.4 are inserted into the slots 5.2.1, the strips 5.4 play a role in preventing the cables from falling out of the cavity between the partitions 5.2.

[0027] In summary, when the DTU body 2 needs to be repaired, the sliding base 4 can be pulled forward through the pinch plate 4.6, and the sliding base 4 moves toward the cabinet door of the terminal cabinet 1 under the guidance of the guide rail 3. The cables connected to the rear wall of the DTU body 2 have a certain amount of excess length to meet the movement requirements of the DTU body 2.

[0028] When maintenance is required on the connection port on the rear wall of the DTU body 2, first tighten the positioning bolt 2.3 to disengage it from the positioning screw hole 4.3, so that the DTU body 2 can be flipped forward along the short axis 2.1 to present the rear wall of the DTU body 2 to the maintenance personnel for easy routine maintenance operations.

[0029] To guide the DTU body 2's rotation and limit its maximum forward tilt angle to 90°, a curved slot 4.5 is provided on the front center of the inner wall of the sliding base 4, concentric with the axis hole 4.2. A roller 2.4 is rotatably mounted in the center of the side wall of the DTU body 2, slidingly engaging along the curved slot 4.5. As the DTU body 2 is tilted, the roller 2.4 rolls along the curved slot 4.5, providing guidance. The two ends of the curved slot 4.5 limit the maximum tilt angle of the DTU body 2 by restricting the position of the roller 2.4.
