[0033] Reference example Figures 1 to 5A primary and secondary fusion ring network box with a wire bundling function comprises a box body 1, and support rails 2 are arranged on both sides of the box body 1, the support rails 2 are provided with a plurality of movable plates 3 that can be lifted and lowered, the movable plates 3 are provided with wire bundling columns 4 that can be moved left and right, both sides of the wire bundling columns 4 are provided with wire bundling parts 41 that can be retracted toward the center, a first spring 5 is arranged in the wire bundling column 4 and acts on the movable plate 3, a liftable wire pressing plate 6 is arranged above the wire bundling part 41, the wire pressing plate 6 is provided with a pressing groove 61, both sides of the pressing groove 61 are provided with inclined surfaces 62 and abut against the outer wall of the wire bundling part 41, and the wire pressing plate 6 is pressed down to make the wire bundling part 41 retract toward the center direction;

[0034] It is worth mentioning that a first position-limiting through hole 21 is provided on one side of the support rail 2, and the first position-limiting through hole 21 limits the range of motion of the movable plate 3;

[0035] It is worth mentioning that a box door 11 is provided on both sides of the box body 1, and the box door 11 is provided with a plurality of rubber threading holes 12 at equal intervals, and the rubber threading holes 12 are used for cables to enter the box body 1, and the rubber threading holes 12 have the function of dustproof and waterproof;

[0036] It is worth mentioning that the cable tie column 4 is provided with a convex column 42, the cable tie portion 41 is arranged on the top of the convex column 42, grooves 43 are arranged on both sides of the convex column 42, the cable tie column 4 is provided with a first blind hole 44, and second limiting through holes 441 are arranged on both sides of the first blind hole 44. The convex column 42 provides support for the cable tie portion 41, the groove 43 is used in conjunction with the convex block 32, the first blind hole 44 provides a guide for the top column 45, and the second limiting through hole 441 limits the telescopic range of the top column 45;

[0037] It is worth mentioning that a top column 45 is slidably provided in the blind hole, and convex bumps 451 are provided on both sides of the top column 45, and are slidably provided in the second limit through hole 441. The two ends of the first spring 5 abut against the first blind hole 44 and the top column 45 respectively. The elastic force of the first spring 5 is applied to the top column 45, so that the top column 45 abuts against the bottom of the guide groove 31, so that the movement of the cable tie column 4 has a damping effect and is fixed at the position after the movement;

[0038] It is worth mentioning that the movable plate 3 is provided with a guide groove 31 for the cable tie column 4 to move, and protrusions 32 are provided on both sides of the top of the movable plate 3 and abut against the groove 43. The two sides of the movable plate 3 are provided with butterfly screws 33, which are slidably arranged in the first limit through hole 21. The protrusions 32 abut against the groove 43 to prevent the cable tie column 4 from rotating during the movement, ensuring that the cable tie portion 41 is always located below the inclined surface 62. When the movable plate 3 moves to the specified position, the butterfly screw 33 is rotated, and its end and head abut against the support guide rail 2, so that the movable plate 3 is fixed in the moved position;

[0039] It is worth mentioning that fastening screws 63 are provided on both sides of the wire pressing plate 6 and are threadedly connected to the movable plate 3. The outer wall of the fastening screw 63 is provided with a second spring 7 and is arranged between the wire pressing plate 6 and the movable plate 3. The wire pressing plate 6 and the movable plate 3 are provided with a second blind hole 8 for accommodating the second spring 7. After the cable is placed on the wire harness portion 41, the wire pressing plate 6 is gradually lowered by tightening the fastening screws 63. When the inclined surface 62 abuts against the outer wall of the wire harness portion 41, the inclined surfaces 62 at the entrance of the pressing groove 61 are wider and narrower as they go inward. Therefore, as the distance between the wire pressing plate 6 and the movable plate 3 becomes smaller, the force of the wire harness portion 41 being squeezed inward by the inclined surface 62 becomes greater, and the clamping force applied to the cable becomes greater; when the fastening screw 63 is loosened, the second spring 7 pushes the wire pressing plate 6 to return to its original position, so that the wire harness portion 41 is returned to its original position.

[0040] The above design scheme can enable the product to have the advantages of wire bundling function and easy maintenance.

[0041] The above content is a further detailed description of the utility model in combination with specific implementation methods. It cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, without departing from the concept of the utility model, they can also make several simple deductions or substitutions, which should be regarded as belonging to the scope of protection determined by the claims submitted for the utility model.
