Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinet installation, in particular to an adjustable installation frame for a power distribution cabinet. Background Art

[0002] High-voltage distribution cabinet refers to an electrical product with a voltage level of 3.6kV to 550kV, which plays the role of switching, controlling or protecting in the power generation, transmission, distribution, power conversion and consumption of the power system.

[0003] High-voltage distribution cabinets are all equipped with mounting frames for installing electrical components. Currently, the mounting frames used in high-voltage distribution cabinets are welded structures, and the positions of the wiring harness brackets on the mounting frames are relatively fixed and cannot be adjusted. Therefore, when installing electrical components, space is wasted or insufficient, which cannot meet the use requirements.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] See also Figures 1 to 4In the utility model, an adjustable mounting frame for a power distribution cabinet includes two mounting plates 1 and a mounting cross frame 2. The mounting cross frame 2 is located on the opposite side of the two mounting plates 1. The opposite side of the two mounting plates 1 is provided with matching holes 3 arranged at equal distances. The left and right sides of the mounting cross frame 2 are provided with mounting grooves 4. A matching block 5 is slidably connected to the inner wall of the mounting groove 4. The matching block 5 is located inside the matching hole 3. A spring 6 is fixedly connected to the inner wall of the mounting groove 4. The other end of the spring 6 is fixedly connected to the matching block 5. A through groove 7 is provided on the inner wall of the mounting groove 4. The bottom of the matching block 5 A synchronous plate 8 is fixedly connected, the synchronous plate 8 passes through the through slot 7 and extends to the bottom of the mounting cross frame 2, a movable slot 9 is provided on the top of the mounting cross frame 2, and evenly distributed movable seats 10 are slidably connected to the inner wall of the movable slot 9, and a mounting hole 11 is provided on the movable seat 10, and two expansion slots 12 are provided on the inner wall of the movable slot 9, and two through holes 13 are provided on the movable seat 10, and a locking shaft 14 is arranged inside the through hole 13, and both ends of the locking shaft 14 respectively pass through the two expansion slots 12 and extend to the outside of the mounting cross frame 2, and both ends of the locking shaft 14 are threadedly connected with nuts.

[0024] A limiting rod 15 is slidably connected to the inner wall of the mounting groove 4 , and the bottom end of the limiting rod 15 penetrates and extends to the bottom of the mounting cross frame 2 . A limiting hole 16 is provided at the bottom of the fitting block 5 , and the limiting hole 16 is arranged corresponding to the limiting rod 15 .

[0025] The mounting plate 1 is connected to the inner wall of the power distribution cabinet by bolts so that the fitting holes 3 on the two sets of mounting plates 1 have the same height, and then the mounting cross frame 2 can be installed. The user pulls the synchronous plate 8 at the bottom, so that the fitting block 5 moves inside the mounting groove 4 along with the synchronous plate 8. The spring 6 begins to shrink under pressure and generates an opposite force. As the synchronous plate 8 continues to move, the fitting block 5 completely enters the interior of the mounting groove 4. At this time, the limiting hole 16 moves to the top of the limiting rod 15. The user pushes the limiting rod 15 upward so that the limiting rod 15 enters the limiting hole 16. At this time, the thrust generated by the spring 6 causes the side of the limiting rod 15 to be stressed, thereby restricting the fitting block 5 from being reset. After the user retracts the fitting blocks 5 on both sides, the mounting cross frame 2 can be lifted to the two sets of mounting plates 1. On the opposite side, after adjusting to the appropriate position, the user pulls the limit rod 15 downward, at this time the spring 6 pushes the fitting block 5 so that the fitting block 5 enters the fitting hole 3, and the two groups of fitting blocks 5 are engaged with the fitting holes 3 to complete the limitation of the installation cross frame 2. The user can release the limitation of the installation cross frame 2 by changing the position of the fitting block 5, and then adjust the installation cross frame 2 to different heights. During the installation process, the user can move the movable seat 10 so that the movable seat 10 moves horizontally inside the movable groove 9, and then change the position of the installation hole 11, so that the internal components of the distribution cabinet can be better installed. After the locking shaft 14 passes through the through hole 13, the user connects the nut to the two ends of the locking shaft 14, so that the nut contacts the installation cross frame 2 to generate friction to limit the movable seat 10.

[0026] In the utility model, the position of the fitting block 5 can be changed by supporting the fitting block 5 through the spring 6, so that the mounting cross frame 2 can be assembled with the fitting holes 3 at different heights on the mounting plate 1, avoiding the waste of space or insufficient space when installing the components of the distribution cabinet, and the fitting block 5 can be limited by the cooperation of the limiting rod 15 and the limiting hole 16. During the adjustment process, there is no need to continuously pull the fitting block 5, which reduces the difficulty of installation. At the same time, the movable seat 10 can be moved arbitrarily inside the movable groove 9, so it can cooperate with the installation positions of different components to improve assembly efficiency.

[0027] See also Figure 2 , wherein: a telescopic rod 17 is arranged inside the spring 6, and two ends of the telescopic rod 17 are fixedly connected to the inner wall of the mounting groove 4 and the fitting block 5 respectively.

[0028] In the present invention, the arrangement of the telescopic rod 17 can limit the engagement block 5, so that the engagement block 5 is always located inside the installation groove 4 to maintain stable movement in the horizontal direction.

[0029] See also Figure 1 , wherein: the front side of the mounting cross frame 2 is provided with evenly distributed scale markings 18 , and the scale markings 18 are located at the top of the expansion slot 12 .

[0030] In the present invention, when the user adjusts the movable seat 10, the adjustment error of the movable seat 10 can be reduced according to the position of the scale mark 18, so that the position of the mounting hole 11 is more suitable for installing the distribution cabinet components, thereby improving the assembly efficiency.

[0031] See also Figure 1 and 4 , wherein: the front and back sides of the movable seat 10 are fixedly connected with a slider 19 , and the slider 19 is slidably connected to the inner wall of the expansion groove 12 .

[0032] In the present invention, the setting of the slider 19 can limit the movable seat 10, so that the movable seat 10 is always located inside the movable groove 9 to maintain stable lateral movement.

[0033] See also Figure 2 , wherein: a soft pad is fixedly connected to the synchronization plate 8, and the soft pad is provided with evenly distributed anti-slip patterns.

[0034] In the utility model, when the user needs to pull the synchronous plate 8, the soft pad can improve the comfort of the user, and the anti-skid pattern can prevent the user from slipping.

[0035] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
