[0026] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0028] See also Figure 1-Figure 6As shown, the utility model is a fence for construction of a distribution transformer, comprising a plurality of boxes 1 and a connecting mechanism 6, wherein the connecting mechanism 6 completes the fixed installation between the two boxes 1 by connecting two of the boxes 1, a warning light 13 is fixedly installed on the top of the box 1, a limited opening 12 is provided on the top of the box 1, the limited opening 12 passes through the top of the box 1, a rotating opening 11 is provided on one side of the box 1, and the rotating opening 11 passes through the other side of the box 1 with one of the narrow sides as the axial center, and two equidistantly arranged fixing rings 2 are fixedly connected inside the box 1, wherein one of the fixing rings 2 is located at the top of the box 1, and the other fixing ring 2 is located at the top of the box 1. Located at the bottom of the box body 1, one of the fixed rings 2 is fixedly connected to the first connecting block 21 on its surface, and the other fixed ring 2 is also fixedly connected to the first connecting block 21. The surfaces of the two fixed rings 2 are rotatably connected to a rotating ring 3, one of the rotating rings 3 is fixedly connected to the second connecting block 31 on its surface close to one end, and the other rotating ring 3 is also fixed to the second connecting block 31. The two rotating rings 3 are fixed by the second connecting block 31. When one of the rotating rings 3 is fixed, the other rotating ring 3 is driven to rotate by the second connecting block 31. The surfaces of the fixed ring 2 and the rotating ring 3 are fixedly connected to a plug-in block 4.

[0029] Depending on the size of the distribution transformer, the number of devices required is also different. When more than four boxes 1 and the internal structure need to be connected and installed through the connecting mechanism 6, it is necessary to change the position of the plug-in block 4 fixed on the surface of the rotating ring 3 inside the box 1 at the four corners of the device to ensure the connection between the devices. At this time, push the plug-in block 4 inside the rotating mouth 11, and the rotating ring 3 starts to rotate. At the same time, the other rotating ring 3 follows the rotation through the second connecting block 31. When one side of the plug-in block 4 on the rotating ring 3 contacts the other narrow side of the rotating mouth 11, it stops rotating.

[0030] By rotating the rotating ring 3 on the surface of the fixed ring 2, when the size of the distribution transformer is too large, the device can be added by changing the direction of the plug-in block 4 fixed on the surface of the rotating ring 3 inside the middle box 1, thereby avoiding the need to replace the device when the size of the distribution transformer is large. At the same time, the space inside the device can be increased by adding the box 1 and the internal structure and the connecting mechanism 6, thereby increasing the construction space for construction personnel.

[0031] By fixing the warning light 13, it is convenient to warn passers-by at night that the construction is going on inside the device, thereby avoiding the situation where passers-by bump into the device due to obstructed vision at night.

[0032] In addition, in specific applications, the warning light 13 is an existing structure, including a lamp holder and a lamp head, wherein the lamp holder is used to fix the warning light 13 on the surface of the box body 1, and the lamp head can emit brightness through the wick inside it.

[0033] In one embodiment, for the above-mentioned connecting mechanism 6, the connecting mechanism 6 includes a first rotating rod 61 and a second rotating rod 62, the first rotating rod 61 and the second rotating rod 62 are in a cross shape, the second rotating rod 62 is rotatably connected to the inside of the first rotating rod 61, the first rotating rod 61 and the second rotating rod 62 are respectively fixedly connected to the inside of the first rotating rod 61 and the second rotating rod 62 with a first moving block 612 and a second moving block 621, and the first moving block 612 and the second moving block 621 pass through the two sides of the first rotating rod 61 and the second rotating rod 62 respectively, the surfaces of the first rotating rod 61 near both ends are slidably connected to the connecting plates 63, and the surfaces of the second rotating rod 62 near both ends are also slidably connected to the connecting plates 63. A sliding groove 632 is provided on the surface of the connecting plate 63, and the sliding groove 632 completely penetrates the connecting plate 63. The inner walls of the sliding groove 632 slide on the surfaces of the first movable block 612 and the second movable block 621 respectively. Two equidistantly arranged blocks 631 are fixedly connected to one side of the connecting plate 63. An insert block 64 is fixedly connected to the surface of the block 631. Four equidistantly arranged fixed blocks 633 are fixedly connected to the surface of the block 631, and the four fixed blocks 633 are grouped in pairs. The two groups of fixed blocks 633 respectively surround the two sides of the insert block 64. A slot 641 is provided on the surface of the insert block 64, and the slot 641 penetrates the four sides of the insert block 64.

[0034] When it is necessary to increase the space inside the device, the second rotating rod 62 and the first rotating rod 61 are controlled to rotate toward the opposite surfaces of the two rod bodies. During the rotation of the two rod bodies, the end close to the ground gradually moves away from the ground, and the end away from the ground gradually approaches the ground. At the same time, the first moving block 612 and the second moving block 621 slide on the inner walls of the sliding groove 632 connected to each other, and squeeze the two connecting plates 63. After the two connecting plates 63 are squeezed, the distance between the two connecting plates 63 gradually becomes farther, and then the distance between the boxes 1 connected on both sides of the connecting mechanism 6 gradually becomes farther, and then the internal space gradually increases.

[0035] Through the relative rotation of the second rotating rod 62 and the first rotating rod 61, during the rotation process, the angle between the two rod bodies toward the ground gradually becomes smaller, and at the same time, the two rod bodies gradually tend to be horizontal, and at the same time, the connecting plate 63 will be squeezed. During the squeezing process, the distance between the two connecting plates 63 gradually becomes farther, and at the same time, the distance between the boxes 1 connected by the connecting mechanism 6 gradually becomes farther, thereby increasing the space inside the device.

[0036] In one embodiment, for the above-mentioned plug-in block 4, a first slide groove 41 is provided on the top of the plug-in block 4, a second slide groove 43 and four equidistantly arranged plug-in grooves 42 are provided on one side of the plug-in block 4, the four plug-in grooves 42 are arranged in groups of two, and the two groups of the plug-in grooves 42 are located on both sides of the second slide groove 43, the plug-in grooves 42 are connected to the first slide groove 41, and a slider 51 is slidably connected to the inner wall of the first slide groove 41, and a telescopic rod 5 is fixedly connected to the surface of the plug-in block 4 located at the top position of the box body 1, and the surface of the telescopic rod 5 is fixedly connected to the slider 51, and the surface of the telescopic rod 5 is fixedly connected to the connecting rod 53, and the connecting rod 53 is also fixedly connected to the slider 51 located at the bottom position, so that the telescopic rod 5 not only drives the slider 51 at the top to move during the movement change, but also can drive the slider 51 at the bottom position to move through the connecting rod 53.

[0037] In addition, in specific applications, the telescopic rod 5 is an existing mechanical structure, the inner rod slides on the inner wall of the outer rod, and a spring is fixed to one end of the inner rod, and the other end of the spring is fixed to the inside of the outer rod.

[0038] In one embodiment, for the above-mentioned fixing block 633 , the surface of the fixing block 633 is slidably connected to the inner wall of the plug-in slot 42 , and the surface of the plug-in block 64 is slidably connected to the inner wall of the second sliding slot 43 .

[0039] When preparing to connect the two box bodies 1, first insert the two plug blocks 64 on one of the connecting plates 63 into the inside of the second slide groove 43, and the fixed block 633 is gradually inserted into the inside of the plug-in groove 42 while following the movement, and at the same time, the sliding block 51 is gradually slid out from the inside of the first slide groove 41 by pulling the telescopic rod 5. At the same time, the sliding block 51 at the bottom of the box body 1 is fixed with the connecting rod 53, and then gradually slides out from the inside of the first slide groove 41 following the pulling of the telescopic rod 5. When the plug block 64 is completely in contact with the inner wall of the second slide groove 43, the telescopic rod 5 is released, and the sliding block 51 gradually returns to the initial state, and at the same time blocks the inner wall of the slot 641 to prevent the plug block 64 from moving. Then, the two plug blocks 64 on the other connecting plate 63 are inserted into the inside of the second slide groove 43 on the other box body 1. After insertion, the connection between the two boxes 1 is completed.

[0040] The installation of the two boxes 1 by the connecting mechanism 6 facilitates the workers to enter the interior of the device, and also facilitates the workers to carry the device after the construction is completed or in the process of preparing for the construction.

[0041] In one embodiment, for the telescopic rod 5 , one end of the telescopic rod 5 is fixedly connected to a pull ring 52 , so that when the pull ring 52 is pulled, the movement of the inner rod inside the telescopic rod 5 can be controlled by pulling the pull ring 52 , thereby facilitating the staff to operate the telescopic rod 5 .

[0042] In summary, with the aid of the above technical solution of the utility model, the number of devices required varies according to the size of the distribution transformer. When more than four boxes 1 and the internal structure need to be connected and installed through the connecting mechanism 6, it is necessary to change the position of the plug-in blocks 4 fixed on the surface of the rotating ring 3 inside the box 1 at the four corners of the device to ensure the connection between the devices. At this time, the plug-in block 4 located inside the rotating port 11 is pushed, and the rotating ring 3 starts to rotate. At the same time, another rotating ring 3 follows the rotation through the second connecting block 31. When one side of the plug-in block 4 on the rotating ring 3 contacts the other narrow side of the rotating port 11, the rotation stops.

[0043] When it is necessary to increase the space inside the device, the second rotating rod 62 and the first rotating rod 61 are controlled to rotate toward the opposite surfaces of the two rod bodies. During the rotation process, the ends of the two rod bodies close to the ground gradually move away from the ground, while the ends away from the ground gradually move closer to the ground. At the same time, the first moving block 612 and the second moving block 621 slide on the inner walls of the sliding grooves 632 connected to them, and squeeze the two connecting plates 63. After the two connecting plates 63 are squeezed, the distance between the two connecting plates 63 gradually becomes farther, and then the distance between the boxes 1 connected on both sides of the connecting mechanism 6 gradually becomes farther, and then the internal space gradually increases;

[0044] When it is necessary to increase the space inside the device, the second rotating rod 62 and the first rotating rod 61 are controlled to rotate toward the opposite surfaces of the two rod bodies. During the rotation process, the ends of the two rod bodies close to the ground gradually move away from the ground, while the ends away from the ground gradually move closer to the ground. At the same time, the first moving block 612 and the second moving block 621 slide on the inner walls of the sliding grooves 632 connected to them, and squeeze the two connecting plates 63. After the two connecting plates 63 are squeezed, the distance between the two connecting plates 63 gradually becomes farther, and then the distance between the boxes 1 connected on both sides of the connecting mechanism 6 gradually becomes farther, and then the internal space gradually increases;

[0045] When preparing to connect the two box bodies 1, first insert the two plug blocks 64 on one of the connecting plates 63 into the inside of the second slide groove 43, and the fixed block 633 is gradually inserted into the inside of the plug-in groove 42 while following the movement, and at the same time, the sliding block 51 is gradually slid out from the inside of the first slide groove 41 by pulling the telescopic rod 5. At the same time, the sliding block 51 at the bottom of the box body 1 is fixed with the connecting rod 53, and then gradually slides out from the inside of the first slide groove 41 following the pulling of the telescopic rod 5. When the plug block 64 is completely in contact with the inner wall of the second slide groove 43, the telescopic rod 5 is released, and the sliding block 51 gradually returns to the initial state, and at the same time blocks the inner wall of the slot 641 to prevent the plug block 64 from moving. Then, the two plug blocks 64 on the other connecting plate 63 are inserted into the inside of the second slide groove 43 on the other box body 1. After insertion, the connection between the two boxes 1 is completed.

[0046] Through the above technical scheme, 1. By rotating the rotating ring 3 on the surface of the fixed ring 2, when the size of the distribution transformer is too large, the device can be added by changing the direction of the plug-in block 4 fixed on the surface of the rotating ring 3 inside the middle part of the box 1, thereby avoiding the need to replace the device when the size of the distribution transformer is large. At the same time, the space inside the device can be increased by adding the box 1 and the internal structure and the connecting mechanism 6, thereby increasing the construction space for construction personnel; 2. Through the relative rotation of the second rotating rod 62 and the first rotating rod 61, during the rotation process, the angle between the two rod bodies toward the ground gradually becomes smaller, and the two rod bodies gradually tend to a horizontal state, and at the same time, the connecting plate 63 will be squeezed. During the squeezing process, the distance between the two connecting plates 63 gradually becomes farther, and at the same time, the distance between the boxes 1 connected by the connecting mechanism 6 gradually becomes farther, thereby increasing the space inside the device.
