The cable holders 9 are inserted into the plug-in slots 27 below the wiring channels 10, so that the wiring is embedded in the cable slots 11 of the cable holders 9. In this way, the wiring can be arranged neatly and orderly, avoiding messy wiring and facilitating subsequent maintenance and repair.
[0028] Operating principle and advantages: In use, the enclosure 2 serves as the main structure of the entire lighting distribution box, providing installation and protection space for internal electrical components. A threaded rod 6 is rotatably mounted on one side of the enclosure. A knob 12 is located on the side of the threaded rod 6 away from the enclosure 2. Rotating the knob 12 rotates the threaded rod 6. A limit rod 7 is fixedly mounted on the side of the enclosure 2 away from the threaded rod 6. The limit rod 7 is parallel to the threaded rod 6, providing guidance for the movement of the connecting plate 20. A door 3 is hinged to one side of the enclosure 2. The door 3 can rotate around the hinge to open and close. The side of the door 3 away from the hinge is engaged with one side of the enclosure 2, specifically through the cooperation of a fixing block 5, a sliding block 22, a locking block 21, a connecting block 4, a sliding groove 13, and a locking groove 25. When the box door 3 is closed, the sliding block 22 slides along the sliding groove 13 inside the connecting block 4, and the locking block 21 is locked into the locking groove 25 under the action of the spring 23, so that the box door 3 is firmly closed; when the box door 3 is opened, simply press the locking block 21 to disengage it from the locking groove 25, and the box door 3 can be rotated open. The outer ring of the threaded rod 6 and the outer ring of the limit rod 7 are both fitted with connecting plates 20. One side of each of the two connecting plates 20 is integrally formed with a mounting plate 16. The mounting plate 16 is used to install various electrical components in the lighting distribution box, such as circuit breakers, contactors, relays, etc. When it is necessary to adjust the position of the mounting plate 16, rotating the knob 12 drives the threaded rod 6 to rotate. Since one of the connecting plates 20 has an internal threaded hole 15, the threaded rod 6 enters the connecting plate 20 through the internal threaded hole 15. The first mounting plate 16 is threaded, while the second mounting plate 20 has a limiting hole 18 inside. The limiting rod 7 slides inside the connecting block 4 through the limiting hole 18. Therefore, the rotation of the threaded rod 6 will drive the threaded connecting plate 20 to move axially along the threaded rod 6. At the same time, under the guidance of the limiting rod 7 and the limiting hole 18, the other mounting plate 20 will also move synchronously, thereby realizing the synchronous adjustment of the positions of the two mounting plates 16. This design allows the mounting plates 16 to be flexibly adjusted according to the size of the installed electrical components, improving space utilization. Inside the housing 2, there are wiring grooves 10 on both sides below the threaded rod 6 and the limiting rod 7. A wire holder 9 is inserted below the two wiring grooves 10. The wiring grooves 10 provide initial guiding space for the arrangement of wiring. The cable tray 9 has a cable tray 11 inside, which can further organize and fix the cable. When installing electrical components, the cable to be connected is first placed into the cable tray 10, and then the cable tray 9 is inserted into the plug slot 27 below the cable tray 10, so that the cable is embedded in the cable tray 11 of the cable tray 9. In this way, the cable can be arranged neatly and orderly, avoiding messy cable, and facilitating subsequent maintenance and repair. The mounting plate 16 has three heat dissipation slots 17 inside. The setting of the heat dissipation slots 17 increases the air circulation channel inside the box 2. When the electrical components in the lighting distribution box are working, the heat generated can be dissipated to the outside of the box 2 through the heat dissipation slots 17, effectively reducing the temperature inside the box 2 and preventing the performance and life of the electrical components from being affected by excessive temperature.
