DETAILED DESCRIPTION

[0024] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0025] Example 1

[0026] A distribution box for electrical engineering, such as Figure 1-Figure 3 As shown, it includes a distribution box 2, a box cover 1 is rotatably connected to the side of the distribution box 2, four sliding shafts 3 are fixedly connected inside the distribution box 2, the four sliding shafts 3 are arranged at the four corners of the distribution box 2, the sliding shafts 3 are provided with annular circular grooves distributed at intervals, a fixed plate 4 is slidably connected to the sliding shaft 3, a sliding groove 10 is provided at the edge of the fixed plate 4, the sliding groove 10 is an arc-shaped sliding groove, a limit shaft 6 is slidably connected in the sliding groove 10, and the limit shaft 6 passes through the two ends of the fixed plate 4 and is slidably connected to two lower clamping plates 7, The two lower clamping plates 7 are symmetrically arranged on both sides of the fixed plate 4, and an annular groove matching the annular groove on the sliding shaft 3 is opened in the lower clamping plate 7. The side of the lower clamping plate 7 away from the limiting shaft 6 is rotatably connected with a rotating shaft 9. The rotating shaft 9 passes through both ends of the fixed plate 4 and is rotatably connected with an upper clamping plate 5. The upper clamping plate 5 is symmetrically arranged on both sides of the fixed plate 4, and the rotating shaft 9 is rotatably connected to the fixed plate 4. The lower clamping plate 7 is rotatably connected to the upper clamping plate 5 through the rotating shaft 9, and the other ends of the two upper clamping plates 5 are connected through a positioning shaft 8.

[0027] like Figure 4 , Figure 7 As shown, a limiting groove 11 is provided on the side of the lower clamping plate 7 away from the rotating shaft 9, a sliding groove corresponding to the limiting groove 11 is provided on the fixed plate 4, the sliding groove is connected to the sliding groove 10, and the limiting shaft 6 is slidably connected in the limiting groove 11.

[0028] like Figure 4-Figure 5 As shown, the upper clamp plate 5 is slidably connected to a ejection pin 12 on the side away from the rotating shaft 9, a spring is fixedly connected between the upper clamp plate 5 and the ejection pin 12, two limit pins 13 are slidably connected inside the limit shaft 6, and a spring is fixedly connected between the end of the limit pin 13 and the limit shaft 6.

[0029] like Figure 6As shown, a trigger column 14 is slidably connected on the lower clamping plate 7 and located on one side of the limiting groove 11. The end of the trigger column 14 extending out of the lower clamping plate 7 is rotatably connected to a clamping plate 16 through a rotating shaft. The end of the clamping plate 16 is hook-shaped, and the middle part of the clamping plate 16 is rotatably connected to a support plate 15 through a rotating shaft. The support plate 15 is fixedly connected to the side of the lower clamping plate 7, and a return spring 17 is arranged between the outer side of the upper clamping plate 5 and the inner side of the clamping plate 16. The return spring 17 is fixedly connected to the clamping plate 16. The elastic force of the compression spring at the end of the limiting pin 13 is greater than the sum of the elastic forces of the spring at the end of the ejection pin 12 and the return spring 17.

[0030] When the height of the fixing plate 4 needs to be adjusted, the box cover 1 is opened, and the limiting shaft 6 is pushed to move inward. The limiting shaft 6 moves inward and slides in the limiting groove 11. When the limiting shaft 6 moves inward to the other end of the limiting groove 11, the end of the limiting pin 13 contacts the lower clamping plate 7, and the spring at the other end of the limiting pin 13 is compressed. Under the action of the reset spring 17, the clamping plate 16 is disengaged from the upper clamping plate 5 and moves outward, so that the clamping plate 16 rotates through the rotating shaft in the middle thereof, and the other end of the clamping plate 16 moves inward to trigger the column 14 Push inward to unlock the upper clamping plate 5 and the lower clamping plate 7. The ejector pin 12 in the upper clamping plate 5 releases the rear spring pressure to push the lower clamping plate 7 downward. At this time, the lower clamping plate 7 is disengaged from the limit of the sliding shaft 3. The limit shaft 6 drives the lower clamping plate 7 to move downward along the sliding groove 10. The lower clamping plate 7 moves downward along the sliding groove 10 with the rotating shaft 9 as the center. The lower clamping plate 7 is unlocked from the sliding shaft 3. In this way, the four pairs of upper clamping plates 5 and lower clamping plates 7 on the fixed plate 4 are opened, and the fixed plate 4 can be pulled up and down to adjust the height of the fixed plate 4.

[0031] When the height adjustment of the fixed plate 4 is completed, the limit shaft 6 is pushed upward, and the limit shaft 6 moves upward to drive the lower clamping plate 7 to move upward along the sliding groove 10. The lower clamping plate 7 moves upward along the sliding groove 10 with the rotating shaft 9 as the center. After the limit shaft 6 moves to the top of the sliding groove 10, the limit shaft 6 is pushed toward the outside of the limit groove 11 under the action of the limit pin 13 releasing the compression spring. The limit shaft 6 slides in the limit groove 11 and pushes the trigger column 14 to move outward. The trigger column 14 moves outward and the clamping plate 16 contacts the upper surface of the upper clamping plate 5 under the action of the middle rotating shaft. The clamping plate 16 contacts the upper surface of the upper clamping plate 5 to compress the reset spring 17, and the lower clamping plate 7 compresses the ejection pin 12 into the upper clamping plate 5. At this time, the upper clamping plate 5 is fitted with the lower clamping plate 7 and is locked with the sliding shaft 3, and the height of the fixed plate 4 can be locked, thereby completing the adjustment of the height of the fixed plate 4.
