[0024] See also Figures 1 to 5In this practical embodiment, an intelligent low-voltage distribution box includes a distribution box body 1. Existing low-voltage integrated intelligent complete distribution boxes are generally equipped with leakage monitoring and fire alarm light intelligent functions, so they will not be explained in detail here. A wire threading cover 2 is provided at the bottom of the distribution box body 1. The bottom of the wire threading cover 2 is provided with wire threading holes 3 arranged at equal intervals. An adjustment mechanism is provided on one side of the wire threading cover 2. Both ends of the adjustment mechanism extend into the wire threading cover 2 and are fixedly connected to two symmetrically arranged clamping plates 4. The side walls of the two clamping plates 4 are provided with wire threading slots 5 corresponding to the wire threading holes 3. The two clamping plates 4 can be used to clamp the wiring cables to prevent the wiring terminals from loosening and falling off due to external force. A sealing mechanism is provided in the wire threading slots 5. A locking mechanism is provided on the side of the wire threading cover 2 away from the adjusting mechanism. Both ends of the locking mechanism are fixedly connected to one end of the two clamping plates 4 respectively.

[0025] The adjusting mechanism includes a first shell 6 that is connected to one side of the threading cover shell 2, and a handwheel rod 7 is inserted and rotatably connected to one side of the first shell 6. One end of the handwheel rod 7 is fixedly connected to a disc 8, and two symmetrically arranged pull rods 9 are hingedly connected on both sides of the disc 8. The far ends of the two pull rods 9 are hingedly connected to a moving block 10, and the two moving blocks 10 are respectively fixedly connected to one end of the two clamps 4. When it is necessary to adjust the spacing between the two clamps 4 according to the thickness of the cable, first, the locking mechanism is unlocked, and then the handwheel rod 7 can be rotated to drive the disc 8 to rotate, and then the two pull rods 9 are pulled to produce a swinging displacement. At this time, the two moving blocks 10 can be pulled toward each other to achieve spacing adjustment, so as to clamp and fix cables of different thicknesses. Then, the locking mechanism can be locked. The operation is simple and can be suitable for clamping and fixing wiring cables of different thicknesses.

[0026] like Figure 5 As shown: the sealing mechanism includes a number of grooves 11 that are evenly spaced and opened on the inner bottom wall of the threading slot 5. The inner bottom wall of the groove 11 is fixedly connected to a first spring 12. One end of the first spring 12 is fixedly connected to a sealing block 13. The sealing block 13 extends into the threading slot 5. When the two splints 4 are displaced, until the two threading slots 5 are clamped to the cable, the sealing block 13 can press against the cable. As the thickness of the cable changes, the sealing blocks 13 at different positions are subjected to different pressures and displace. At this time, the relative first springs 12 are squeezed and contracted to generate elastic force, and the sealing block 13 is tightly fitted against the cable, which can seal and reduce the gap between the threading slot 5 and the cable, thereby preventing mice or insects from entering the distribution box body 1 from the threading hole 3. The structure is simple and the sealing operation is convenient. It is not necessary to seal completely here, and the existing gap is not enough for mice or insects to enter.

[0027] like Figure 5As shown, the locking mechanism includes a second shell 14 connected to the threading cover shell 2, and the inner wall of the second shell 14 is provided with two movable shells 15, and the two movable shells 15 are fixedly connected to the two clamping plates 4 respectively. The inner bottom wall of the movable shell 15 is fixedly connected to a second spring 16, and one end of the second spring 16 is fixedly connected to a T-shaped clamping block 17. The side wall of the second shell 14 is provided with clamping holes 18 arranged at equal intervals. One end of the T-shaped clamping block 17 passes through the movable shell 15 and is inserted into the clamping hole 18. When the T-shaped clamping block 17 is inserted into the clamping hole 18, the displacement of the movable shell 15 can be locked, thereby positioning the displacement of the clamping plate 4, and thus the cable clamping is more stable. When it is necessary to adjust the displacement of the clamping plate 4, the T-shaped clamping block 17 is first pushed to retract into the movable shell 15. At this time, the second spring 16 is squeezed and contracted to generate elastic force. When the T-shaped clamping block 17 is completely separated from the clamping hole 18, the movable shell 15 can be displaced, which can move the clamping plate 4.

[0028] like Figure 5 As shown, the inner wall of the second shell 14 is slidably connected to the outer wall of the movable shell 15, so that the displacement of the movable shell 15 is more stable.

[0029] like Figure 5 As shown, a sliding hole is opened on the side wall of the movable shell 15, and the T-shaped block 17 is arranged through the sliding hole to facilitate the displacement of the T-shaped block 17.

[0030] like Figure 4 As shown, the inner wall of the first shell 6 is slidably connected to the side wall of the moving block 10, so that the displacement of the moving block 10 is more stable.

[0031] like Figure 3 As shown, the lower side wall of the clamping plate 4 is frictionally connected to the inner bottom wall of the threading cover 2, thereby improving the sealing performance of the threading hole 3.

[0032] Working principle: When the distribution box body 1 needs to adjust the clamping plate 4 for displacement after wiring, the T-shaped clamping block 17 is first pushed to move and retract into the movable shell 15. At this time, the second spring 16 is squeezed and contracted to generate elastic force. When the T-shaped clamping block 17 is completely separated from the clamping hole 18, the movable shell 15 can be displaced, so that the clamping plate 4 can be moved;

[0033] Then, the hand wheel rod 7 is rotated to drive the disc 8 to rotate, and then the two pull rods 9 are pulled to produce a swing displacement. At this time, the two moving blocks 10 can be pulled toward each other to achieve spacing adjustment, so that cables of different thicknesses can be clamped and fixed. Then, the locking mechanism can be locked. The operation is simple and can be applied to clamp and fix wiring cables of different thicknesses.

[0034] Due to the different thicknesses of the cables, the sealing blocks 13 at different positions are subjected to different pressures and thus displaced. At this time, the relative first springs 12 are squeezed and contracted to generate elastic force, and the sealing blocks 13 fit tightly against the cables, thereby sealing and narrowing the gap between the threading slots 5 and the cables, thereby preventing mice or insects from entering the distribution box body 1 through the threading holes 3. The structure is simple and the sealing operation is convenient.
