Description

Technical Field

[0001] This utility model relates to the field of power transmission and transformation engineering technology, specifically to a power transmission and transformation engineering distribution box and cable fixing bracket. Background Technology

[0002] In the field of power transmission and transformation engineering, distribution boxes are key equipment for power distribution and control. Numerous cables and electrical components need to be rationally arranged inside. However, traditional power transmission and transformation distribution boxes have a simple structure, mainly welded from multiple steel plates. They lack internal cable fixing functions, and the cables between various electrical components are usually scattered inside the distribution box, easily leading to cable tangling. This not only poses safety hazards but also makes it inconvenient for workers to maintain the equipment later. Some workers use multiple cable ties to bind all the cables together and then cut off the excess length with scissors. While this method solves the problem of cable tangling, it is cumbersome, and the cable ties are difficult to open. Later maintenance can only be done by cutting the ties with scissors, and after maintenance, new cable ties need to be used to re-tie the cables together, wasting both time and resources.

[0023] like Figures 1 to 5 As shown, this embodiment provides a cable fixing bracket, including a base plate 1 and a cable fixing structure 3. A first insert block 302 is fixed on the base block 301 of the cable fixing structure 3. A second slot 304 is opened on the top of both the base block 301 and the expansion block 303 of the cable fixing structure 3. A second insert block 305 that can cooperate with the second slot 304 is fixed on the bottom of both. The expansion block 303 can be installed on the base block 301 or another expansion block 303 through the cooperation of the second slot 304 and the second insert block 305.

[0024] Both the base block 301 and the expansion block 303 have cable fixing buckles 4 installed on their front sides. The bottom of the U-shaped plate 401 is horizontally fixed to the front sides of the base block 301 and the expansion block 303 in the cable fixing buckle 4. The cable can be clipped inside the U-shaped plate 401. The two ends of the U-shaped plate 401 have third slots 403. The upper and lower ends of the baffle 402 have fourth slots 404. The fourth slots 404 of the baffle 402 are inserted into the third slots 403 of the U-shaped plate 401 to complete the installation of the baffle 402 at the opening of the U-shaped plate 401. After the baffle 402 is installed, it can prevent the cable from falling out of the U-shaped plate 401.

When the first insert block 302 is directly inserted into the first slot 2, the base block 301 and the expansion block 303 of the cable fixing structure 3 are vertically distributed, which can organize and fix multiple horizontally arranged cables. When the first insert block 302 is rotated 90° and then inserted into the first slot 2, the base block 301 and the expansion block 303 of the cable fixing structure 3 are horizontally distributed, which can organize and fix multiple vertically arranged cables. Example

[0026] This embodiment provides a power transmission and transformation engineering distribution box, including the cable fixing bracket described in Embodiment 1, and also includes a box body 6. Vertically arranged columns 7 are fixed on both sides of the rear side wall of the inner cavity of the box body 6. Multiple vertically distributed fifth slots 8 are provided on the opposite side of the two columns 7. The fifth slots 8 on the two columns 7 are paired and face forward, allowing the third insert 5 at the end of the base plate 1 to be inserted. By inserting the third insert 5 at both ends of the base plate 1 into the fifth slots 8 on the two columns 7 respectively, the installation of the base plate 1 inside the box body 6 can be completed.

[0027] A horizontally fixed partition 9 is fixed on the column 7 and between two adjacent fifth slots 8. A U-shaped notch 10 is opened on the side of the partition 9. The threaded rod 11 is placed inside the U-shaped notch 10 of the two adjacent partitions 9, so that the threaded rod 11 blocks the front of the base plate 1. The bottom end of the threaded rod 11 is fixed with a clamping plate 12, and the top end is fitted with a washer 13 and connected to a nut 14 by thread. The two partitions 9 are located between the clamping plate 12 and the washer 13. By tightening the nut 14, the clamping plate 12 and the washer 13 clamp the two partitions 9, thereby fixing the threaded rod 11 on the partition 9, thus restricting the position of the base plate 1 and preventing the third insert 5 from dislodging from the fifth slot 8.

[0028] A horizontally mounted electrical component mounting bracket 15 is installed on the rear side wall of the inner cavity of the enclosure 6 by screws for installing electrical components. The front of the enclosure 6 has an opening and a door 16 is installed by hinge. A lock is installed between the enclosure 6 and the door 16 to ensure the safety of the equipment inside the enclosure 6. The enclosure 6 also has a through hole for cables to pass through.

[0029] Working principle and usage process of this utility model: When using the power distribution box for this power transmission and transformation project, first install the electrical components onto the electrical component mounting bracket 15 inside the box 6, then assemble the cable fixing bracket. Based on the distribution of the electrical components, install the base plate 1 at a suitable height inside the box. Insert the third inserts 5 at both ends of the base plate 1 into the fifth slots 8 on the two uprights 7 inside the box, so that the base plate 1 is initially positioned inside the box 6. Then place the threaded rod 11 inside the U-shaped notch 10 on the side of the two partitions 9, so that the threaded rod 11 blocks the front of the base plate 1. Then put the washer 13 on the top of the threaded rod 11 and tighten the nut 14, so that the two partitions 9 are located between the clamp 12 and the washer 13. By tightening the nut 14, the threaded rod 11 is fixed between the two partitions 9, thereby fixing the position of the base plate 1. Then assemble the cable fixing structure 3. Based on the number of cables to be fixed, select an appropriate number of expansion blocks 303 and install the expansion blocks 303 onto the base block 301 through the cooperation of the second slot 304 and the second plug 305, or onto the expansion blocks 303 that have already been installed on the base block 301. After that, install an appropriate number of the assembled cable fixing structures 3 onto the base plate 1 through the cooperation of the first slot 2 and the first plug 302, and adjust their horizontal position to complete the overall assembly of the cable fixing bracket. Then connect all the cables between the electrical components, and then insert all the cables into the U-shaped plates 401 of the different cable fixing buckles 4 in sequence. Next, insert the fourth slots 404 on the upper and lower sides of the baffle 402 into the third slots 403 on the two sides of the U-shaped plate 401, so that the baffle 402 is installed at the opening position of the U-shaped plate 401, thereby neatly fixing the cables in the box 6. Finally, close and lock the box door 16 to ensure the safety of the equipment and cables in the box 6.
