DETAILED DESCRIPTION

[0024] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0025] like Figure 1-Figure 7 As shown, the present embodiment provides an adjustable distribution box, comprising a box body 1 and a base plate 2, wherein the base plate 2 is fixedly mounted on the bottom of the box body 1, and a plurality of supporting legs 3 are arranged below the base plate 2, a rack 4 is movably mounted inside the supporting leg 3, one end of the rack 4 is fixedly connected to the base plate 2, a gear 5 meshingly connected to the rack 4 is rotatably mounted inside the supporting leg 3, a plurality of limiting holes 6 are provided on the rack 4, a crank 7 connected to one side of the gear 5 is rotatably mounted on the supporting leg 3, a fixed switch 8 is fixedly mounted on one side of the supporting leg 3, the fixed switch 8 comprises a sleeve 9 fixedly mounted on one side of the supporting leg 3, a latch 10 movably inserted into the sleeve 9 and penetrating into the limiting hole 6, a first spring 11 is sleeved on the surface of the latch 10, a diameter of one end of the latch 10 is larger than a diameter of the other end, and two ends of the first spring 11 are respectively connected to the surface of the latch 10 and the inner wall of the sleeve 9.

[0026] In this embodiment, when the distribution box is installed on an uneven ground or there are obstacles, the bolt 10 is pulled outward to move away from the inside of the limiting hole 6. When the bolt 10 moves outward, since the diameter of one end of the bolt 10 is greater than the diameter of the other end, the bolt 10 can squeeze the first spring 11 to shrink when it moves upward. At the same time, the crank 7 is turned to drive the gear 5 to rotate. The gear 5 can roll on the rack 4 when it rotates, so that the height of the support leg 3 can be adjusted to ensure that the bottom plate 2 is always Keep it level, avoid the situation that when the height is uneven or the ground is uneven, the bottom of the distribution box cannot be kept level with the ground, resulting in unstable installation affecting the use effect. When adjusted to the appropriate height, release the latch 10 and use the resilience of the first spring 11 to make the latch 10 rebound to the inside of the limiting hole 6 to limit and fix the rack 4. Through the arrangement of the sleeve 9, the latch 10, the first spring 11, and the limiting hole 6, it is convenient to quickly limit and fix the rack 4, and indirectly limit and fix the support leg 3 after the height is adjusted.

[0027] like Figure 1-Figure 3 As shown, a plurality of fixed blocks 12 are fixedly installed on the inner wall of the box body 1, a plurality of positioning holes 13 are opened on the fixed block 12, a slide groove 14 is opened on the upper surface of the fixed block 12, a push block 15 is movably inserted into the slide groove 14 and penetrates into the positioning hole 13, a clamping groove 16 is opened on one side of the inner wall of the slide groove 14, a second spring 17 is installed in the clamping groove 16, two ends of the second spring 17 are respectively connected to the inner wall of the clamping groove 16 and one end of the push block 15, a pressure plate 18 is fixedly installed on one end of the push block 15, and a handle 19 is fixedly installed on the upper surface of the push block 15.

[0028] In this embodiment, when the distribution box is in use, there are often a large number of wires inside. Pulling the handle 19 toward the slot 16 drives the push block 15 to slide, squeezing the second spring 17 to shrink until the pressure plate 18 is away from the inside of the positioning hole 13, so as to facilitate passing each group of wires through the positioning hole 13. When the wires pass through the positioning hole 13, loosening the handle 19 and utilizing the resilience of the second spring 17, the push block 15 can drive the pressure plate 18 to move toward the positioning hole 13, and the pressure plate 18 can squeeze and fix the wires inside the positioning hole 13, so that the wires in the distribution box are more orderly. This can reduce the probability of accidents such as short circuits and poor contact, and improve the safety of electricity use.

[0029] like Figure 1-2As shown, mounting grooves 20 are provided on both sides of the inner wall of the box body 1, and a filter screen 28 is fixedly installed on the mounting groove 20. A plurality of support frames 21 are fixedly installed on the inner wall of the mounting groove 20, and a dual-axis motor 22 is fixedly installed on the support frame 21. A spiral blade 23 is installed at one end of the dual-axis motor 22, and the other end of the dual-axis motor 22 is movably inserted into the outer surface of the filter screen 28 and is connected to a turntable 24. A plurality of cleaning brushes 25 are fixedly installed on the surface of the turntable 24, and the cleaning brushes 25 are in contact with the surface of the filter screen 28.

[0030] In this embodiment, through the setting of the dual-axis motor 22, the spiral blade 23 and the cleaning brush 25 on the turntable 24 can be driven to rotate at the same time, so that the spiral blade 23 draws air outward to cool the distribution box when rotating, thereby preventing the electrical equipment inside the distribution box from overheating and causing the performance of the equipment to decline. Through the setting of the filter 28, dust in the air can be filtered and prevented from entering the distribution box, thereby preventing dust from adhering to the electrical appliances inside the distribution box, resulting in poor heat dissipation, overheating, short circuit and other problems. At the same time, the cleaning brush 25 can clean the dust on the surface of the filter 28 while rotating, thereby preventing dust accumulation and blockage, thereby affecting the air circulation and affecting the heat dissipation effect.

[0031] like Figure 1 As shown, a protective door 26 is movably installed on the front end surface of the box body 1, and an observation window 27 is provided on the surface of the protective door 26.

[0032] In this embodiment, the protective door 26 can protect the electrical components inside the distribution box, and the observation window 27 can facilitate observation of the internal operation of the distribution box without opening the protective door 26.

[0033] like Figure 1-Figure 7As shown, the principle of the easily adjustable distribution box provided in this embodiment is as follows: when the distribution box is installed on an uneven ground or there are obstacles, the bolt 10 is pulled outward to move away from the inside of the limiting hole 6. When the bolt 10 moves outward, since the diameter of one end of the bolt 10 is larger than the diameter of the other end, the bolt 10 can squeeze the first spring 11 to contract when it moves upward, and at the same time, the crank 7 is turned to drive the gear 5 to rotate. The gear 5 can roll on the rack 4 when rotating, so that the height of the support leg 3 can be adjusted. The bottom plate 2 is ensured to remain level at all times, and the bottom of the distribution box is prevented from being unable to remain level with the ground when the height is uneven or the ground is uneven, resulting in unstable installation and affecting the use effect. When the height is adjusted to a suitable level, the latch 10 is released and the resilience of the first spring 11 is utilized to make the latch 10 rebound to the inside of the limiting hole 6 to limit and fix the rack 4. The arrangement of the sleeve 9, the latch 10, the first spring 11 and the limiting hole 6 facilitates the rapid limit and fixation of the rack 4, and indirectly limits and fixes the support leg 3 after the height is adjusted.
