DETAILED DESCRIPTION

[0026] The features and performances of the utility model are further described in detail in combination with embodiments.

[0027] The adjustable cable trench box of the utility model utilizes the cooperation of the adjusting cover plate and the cable trench mounting hole, the position of the adjusting cover plate can be adjusted, the position of the cable trench connected to the adjusting cover plate is adjusted, and the requirement of different installation distances from the cable trench edge is met.

[0028] As a basic scheme, as shown in Figures 1-6 The adjustable cable trough box includes a box body 1, the box body 1 includes a top wall 2, an outer end wall 3 corresponding to the side of the cable trench away from the electrical equipment, an inner end wall 4 opposite to the outer end wall 3, and a side wall 5 connected between the inner end wall and the outer end wall, the bottom of the box body 1 is open, and the length of the box body 1 is greater than the width of the cable trench to be matched, so that the cable trough box can completely cover the cable trench, and the gap between the cable trough box and the cable trench caused by the deviation in the construction process of the cable trench is avoided, and the overall aesthetic appearance is affected. The cable trough mounting hole 6 is arranged on the top wall 2 of the box body 1, and the cable trough 7 is mounted in the cable trough mounting hole 6. One end of the cable trough 7 is embedded in the box body 1, which not only prevents the cable trough 7 from falling off or deviating when the cable is pulled out, but also helps to store and constrain the cable to be pulled out in advance at the embedded section of the cable trough 7. The cable in the cable trench passes through the box body 1 and is pulled out from the cable trough 7 to be connected to the electrical equipment. The cable trough mounting hole 6 leaves an adjustment interval on the side of the cable trough 7 close to the outer end wall 3 in the length direction of the box body 1. The adjustment cover plate 8 covering the adjustment interval is arranged on the top wall 2 of the box body 1 on the side of the cable trough 7 close to the outer end wall 3. The adjustment cover plate 8 has an adjustment compensation part overlapping with the top wall 2 of the box body 1 in the length direction of the box body 1. The adjustment compensation part can provide a moving space for the adjustment cover plate 8 on the top wall 2 of the box body 1. The cable trough 7 changes position with the movement of the adjustment cover plate 8 in the adjustment compensation part to meet the requirement of different installation distances of the cable trough 7 and the cable trench.

[0029] As a preferred embodiment, as shown in Figure 1 The cable trough 7 and the adjustment cover plate 8 are fixedly connected. The fixed connection between the cable trough 7 and the adjustment cover plate 8 facilitates the movement of the adjustment cover plate 8 together with the cable trough 7, thereby achieving the purpose of changing the position of the cable trough 7. Specifically, the connection plate 11 can be used to connect the cable trough 7 and the adjustment cover plate 8, and the connection plate 11 is perpendicular to the adjustment cover plate 8. In this way, the contact area between the connection plate 11 and the cable trough 7 can be increased, thereby improving the stability of the connection. Then, the bolts can be arranged on the connection plate 11 to connect and fix the cable trough 7 and the adjustment cover plate 8. The connection plate 11 and the adjustment cover plate 8 can also be designed as an integral design to enhance the stability of the connection. In other embodiments, welding or bonding can also be used to fixedly connect the cable trough 7 and the adjustment cover plate 8.

The cooperation between the long holes 9 and the locking bolts 10 makes the mounting connection between the adjustment cover plate 8 and the top wall 2 simple and convenient. When the adjustment cover plate 8 needs to be adjusted to a specified position, the adjustment or fixation between the adjustment cover plate 8 and the top wall 2 can be completed by loosening or tightening the locking bolts 10. Moreover, the cooperation between the long holes 9 and the locking bolts 10 has high installation flexibility. Whether the adjustment distance is long or short, the locking bolts 10 are relatively moved along the hole wall of the long hole 9. After the cable groove 7 is adjusted to the required position, the locking bolts 10 are tightened to complete the fixation. In addition, the structure of the long hole 9 and the locking nut is relatively simple, which is convenient for processing and installation, thereby improving the convenience of the cable groove box assembly. In other embodiments, as shown in Figure 6 long holes 9 extending along the length direction of the box body 1 can be arranged on one of the adjustment cover plate 8 and the top wall 2, and only a bolt hole for the locking bolt 10 to pass through is arranged on the other one.
