A groove 406 adapted to the connecting block 401 is provided inside the cable trough 1, and two grooves 406 are provided inside the groove 406. 5, the card slot 407 is snap-fitted with the card block 405; the connecting block 401 is placed into the groove 406 in the cable trough 1, so that the connecting block 401 can drive the two card blocks 405 to slide downward along the inner wall of the groove 406. When sliding to the inside of the groove 406, the two card blocks 405 can be snap-fitted with the card slot 407 under the action of the spring 1 404, so that the cable trough 2 2 can be snap-fitted with the cable trough 1 1, thereby increasing the number of cable troughs in the horizontal direction.

[0032] Two oblique grooves 408 adapted to the clamping block 405 are formed inside the groove 406 , and the outer surface of the connecting block 401 is fixed to the upper surface of the cable trough 2 2 .

[0033] Please refer to Figure 4 The locking mechanism 5 includes a lock body 1 501 and a lock body 2 502. The lock body 1 501 and the lock body 2 502 are both provided with a special-shaped groove 1 503. A lock tongue 504 is rotatably connected to the interior of each special-shaped groove 1 503. A connecting rod 505 is fixed to the outer surface of the lock tongue 504. A special-shaped groove 2 506 is provided to the interior of each special-shaped groove 1 503. A fixing column 507 is fixed to the interior of the special-shaped groove 2 506. A spring 2 508 is fixed between each fixing column 507 and the connecting rod 505.

[0034] A slider 509 is fixed to the end of the lock body 1 501 and the lock body 2 502 that are close to each other, and a slide groove 510 that matches the slider 509 is provided inside each of the lock body 1 501 and the lock body 2 502. When the lock body 1 501 and the lock body 2 502 are moved close to each other, since the outer surfaces of the lock body 1 501 and the lock body 2 502 slide in contact with each other, the two lock tongues 504 can drive the connecting rod 505 to rotate in the special-shaped groove 1 503, so that the inclined surfaces of the two lock tongues 504 are parallel to the lock body 1 501 or the lock body 2 502. When the two sliders 509 on the lock body 1 501 and the lock body 2 502 slide into the two slide grooves 510, under the action of the spring 2 508, the two connecting rods 505 can rotate close to the lock body 1 501 or the lock body 2 502, thereby driving the two lock tongues 504 in the special-shaped groove 1 503. By rotating in the special-shaped groove 1 503, a part of the two locking tongues 504 is rotated into the other special-shaped groove 1 503, thereby realizing the locking of the lock body 1 501 and the lock body 2 502, and then realizing the locking of the cable groove 1 1 and the cable groove 3 3, and increasing the number of cable grooves from the longitudinal direction; through the coordinated arrangement of the clamping mechanism 4 and the locking mechanism 5, the number of cable grooves can be increased from the transverse and longitudinal directions according to actual use requirements, and different cables can be placed in different cable grooves, so that the cables do not affect each other, avoid the situation where multiple cables are entangled with each other, can quickly find the required cables, and facilitate the maintenance of the cables.

[0035] A limiting block 511 is fixed inside each of the special-shaped grooves 503 , and the outer surface of the limiting block 511 is slidably connected to the inside of the locking tongue 504 .

[0037] Please refer to Figure 5 The anti-slip mechanism 6 includes a fixed block 601 and a stopper 602. A mechanism slot 603 is provided inside the fixed block 601. A clamping rod 604 is hinged inside the fixed block 601 through a hinge column. One end of the clamping rod 604 away from the fixed block 601 is clamped with the stopper 602. A spring 3 605 is fixed between the inner bottom wall of the mechanism slot 603 and the clamping rod 604. Pressing the clamping rod 604 in the anti-slip mechanism 6 downward first can make the clamping rod 604 rotate downward along the hinge column in the mechanism slot 603. At this time, the clamping connection between the clamping rod 604 and the stopper 602 can be released, and the cable can be placed in the cable slot. The clamping rod 604 is released. Under the action of the spring 3 605, the clamping rod 604 can be rotated upward along the hinge column in the mechanism slot 603, thereby realizing the clamping connection between the clamping rod 604 and the stopper 602, effectively avoiding the situation where the cable is lifted after being hung up and causing the hook to be unhooked, thereby improving the safety factor of cable hanging.

[0038] The side of the cable trough 1 away from the hook 7 is fixed to the outer surface of the stopper 602, and the side of the fixing block 601 away from the stopper 602 is fixed to the outer surface of the cable trough 1.

[0039] When the utility model is in use: when the number of cable troughs needs to be increased horizontally, the connecting block 401 is placed in the groove 406 in the cable trough 1, so that the connecting block 401 can drive the two clamping blocks 405 to slide downward along the inner wall of the groove 406. When sliding to the inside of the groove 406, under the action of the spring 1 404, the two clamping blocks 405 can be clamped with the clamping groove 407, so that the cable trough 2 2 can be clamped with the cable trough 1 1, and the number of cable troughs can be increased horizontally; when the number of cable troughs needs to be increased vertically, the lock body 1 501 and the lock body 2 502 are moved closer to each other. Since the outer surfaces of the lock body 1 501 and the lock body 2 502 slide and contact with each other, the two lock tongues 504 can drive the connecting rod 505 The two locking tongues 504 rotate in the special-shaped groove 1 503, so that the inclined surfaces of the two locking tongues 504 are parallel to the lock body 1 501 or the lock body 2 502. When the two sliders 509 on the lock body 1 501 and the lock body 2 502 slide into the two sliding grooves 510, under the action of the spring 2 508, the two connecting rods 505 can be rotated close to the lock body 1 501 or the lock body 2 502, thereby driving the two locking tongues 504 to rotate in the special-shaped groove 1 503, so that a part of the two locking tongues 504 rotates into the other special-shaped groove 1 503, thereby realizing the locking of the lock body 1 501 and the lock body 2 502, and then realizing the locking of the cable trough 1 1 and the cable trough 3 3, and increasing the number of cable troughs in the longitudinal direction, and the number of cable troughs can be increased according to actual use requirements;

[0040] Placing different cables in different cable troughs prevents the cables from interfering with each other and avoids the situation where multiple cables are entangled with each other, so that the required cables can be found quickly and the cables can be easily inspected and repaired. When placing the cables in the cable trough, first press down the clamping rod 604 in the anti-slip mechanism 6, so that the clamping rod 604 can be rotated downward along the hinged column in the mechanism groove 603. At this time, the clamping connection between the clamping rod 604 and the stopper 602 can be released, and the cables can be placed in the cable trough. After loosening the clamping rod 604, the clamping rod 604 can be rotated upward along the hinged column in the mechanism groove 603 under the action of the spring three 605, so as to realize the clamping connection between the clamping rod 604 and the stopper 602, effectively avoiding the situation where the cables are lifted up after being hung up and caused to be unhooked, thereby improving the safety factor of cable hanging.
