Detailed implementation manners

[0028] Refer to Figure 1 、 2 、 3, 4 and 5 to describe in detail an embodiment of installing electronic components in a distribution box:

[0029] A distribution box includes a back plate 11, and a top plate 12 and a bottom plate 13 fixedly connected to the upper and lower sides of the back plate 11 respectively. Two pairs of fixed hinges 14 are fixedly connected to the left and right sides of the back plate 11 respectively. A movable hinge 23 is rotatably connected to each fixed hinge 14. A first side plate 21 and a second side plate 22 are fixedly connected to the two pairs of movable hinges 23 respectively. Fixed shafts 16 corresponding to each other are fixedly connected to the corners on the outer sides of the top plate 12 and the bottom plate 13. A sealing plate 32 is rotatably connected to each fixed shaft 16. A door panel 31 is fixedly connected to the two sealing plates 32.

[0030] Common distribution boxes are fixed boxes, and only the cabinet door can rotate. When opening the cabinet door, mounting plates are installed on the back plate, the upper and lower panels, the left and right side panels and the cabinet door of the distribution box, and then guide rail boards are installed on the mounting plates for fixation, and then various electronic components are installed on the guide rail boards; when installing the mounting plates, guide rails and electronic components, it is not convenient to operate the electronic components. However, the first side plate 21 and the second side plate 22 can rotate under the cooperation of the fixed hinge 14 and the movable hinge 23. The first side plate 21 and the second side plate 22 expand towards the two sides of the back plate 11. After the expanded first side plate 21 and second side plate 22, the obstacles during the installation of electronic components are reduced, and the convenience of installing electronic components in the distribution box is increased; when closing the expanded first side plate 21 and second side plate 22 after installing the electronic components, rotate the first side plate 21 and the second side plate 22 until the first side plate 21 and the second side plate 22 are attached to the back plate 11, the top plate 12 and the bottom plate 13. When the door panel 31 rotates around the axes of the two fixed shafts 16 and the door panel 31 is opened, it is more convenient to install mounting plates, guide rails and electronic components on the back plate 11, the top plate 12, the bottom plate 13 and the door panel 31.

[0031] Refer to Figure 1 、 2, 3 and 4, detailed description of the embodiment of limiting the first side plate 21 and the second side plate 22 for fixing:

[0032] A pair of clamping sleeves 24 are fixedly connected to the inner walls of the edges of the first side panel 21 and the second side panel 22 away from the back panel 11, and clamping columns 15 clamped with the clamping sleeves 24 are correspondingly arranged on the top panel 12 and the bottom panel 13. When the first side panel 21 and the second side panel 22 are rotated to fit the edges of the back panel 11, the top panel 12, and the bottom panel 13, until the clamping sleeve 24 is clamped on the clamping column 15, the first side panel 21 and the second side panel 22 are fixed by limiting the clamping sleeve 24 through the clamping column 15, so that the first side panel 21 and the second side panel 22 can be unfolded to increase convenience when installing the hanging board, the guide rail and the electronic components. After the installation of the electronic Yuannian is completed in the distribution box, the first side panel 21 and the second side panel 22 are rotated and fixed, and the distribution box is closed.

[0033] refer to Figure 1 , 3 , 5, 6 and 7, detailed description of the embodiment of locking the door panel 31:

[0034] A hanging sleeve 33 is fixedly connected to the edge of the free end of the door panel 31 , a fixed sleeve 25 is fixedly connected to the second side panel 22 , a sliding rod 41 is slidably connected to the fixed sleeve 25 , and a hanging rod 42 inserted into the hanging sleeve 33 is fixedly connected to the sliding rod 41 . After completing the installation of the electronic components in the distribution box, when closing the door panel 31, manually pick up the sliding bar 41 and slide it upward to rotate the door panel 31 until the door panel 31 is in contact with the edge of the second side panel 22. Pushing the sliding bar 41 before this can avoid movement interference between the hanging rod 42 and the hanging sleeve 33. When the door panel 31 is rotated until the hanging sleeve 33 corresponds to the hanging rod 42 up and down, release the sliding bar 41. Under its own gravity, a hole is provided on the hanging sleeve 33, which can be a through hole or a blind hole. The hanging rod 42 slides into the hole of the hanging sleeve 33, thereby limiting the movement of the hanging sleeve 33 again and realizing the limiting of the hanging sleeve 33 and the door panel 31. When the door panel 31 needs to be opened again, the sliding bar 41 is pushed to drive the hanging rod 42 to disengage from the hanging sleeve 33. At this time, the hanging rod 42 loses the limiting position on the hanging sleeve 33, so that the door panel 31 can be rotated again.

[0035] refer to Figure 8 , 9 and 10, detailing an embodiment of increasing the area for installing electronic components in a distribution box:

[0036] The top plate 12 and the bottom plate 13 are fixedly connected with slideway frames 51. A slide pipe 53 is slidably connected between the two slideway frames 51. The slide pipe 53 is fixedly connected with a middle plate 54. The middle plate 54 is located in the middle of the first side plate 21 and the second side plate 22, and can divide the space inside the distribution box into two parts. The middle plate 54 can add a plate for installing electronic components inside the distribution box, increasing the area of the plate for installing electronic components inside the distribution box and making more full use of the space inside the distribution box. The slide pipe 53 can slide within the two slideway frames 51, and the slide pipe 53 and the middle plate 54 can slide. When the slide pipe 53 slides to the front ends of the two slideway frames 51, it is more convenient to install electronic components on the middle plate 54, increasing the convenience of installing electronic components in the distribution cabinet. At the same time, when installing electronic components on the middle plate 54, an outgoing line body needs to be reserved to prevent the slide pipe 53 and the middle plate 54 from being restricted by the line body and unable to slide.

[0037] Reference Figure 9 and 10 , a detailed description of the embodiment in which the middle plate 54 rotates after being drawn out:

[0038] Round frames 52 are provided at the ends of the two slideway frames 51. The slide pipe 53 is a circular pipe symmetrically provided with planes, and the diameter of the slide pipe 53 is the same as the inner diameter of the round frame 52. A circular hole is provided in the middle of the round frame 52, and the slide pipe 53 can rotate within the circular holes at the ends of the two round frames 52. Thus, when the middle plate 54 and the slide pipe 53 rotate, the spaces on both sides of the middle plate 5 can be exposed, giving the operator a wider space and field of vision and making it more convenient to operate and maintain the electronic components inside the distribution box.

[0039] Reference Figure 10 , a detailed description of the embodiment for increasing the heat dissipation inside the distribution box:

[0040] A plurality of through holes are provided on the middle plate 54. Air can circulate in the spaces on both sides of the middle plate 54 inside the distribution box through the plurality of through holes. The distribution box usually dissipates heat through a fan, and the fan is usually arranged on two parallel vertical planes. Therefore, through holes can be processed on the door panel 31 and the back panel 11 and fans can be installed. The fans installed on the door panel 31 and the back panel 11 can be respectively arranged on both sides of the middle plate 54, so as to drive the air circulation inside the distribution box through the rotation of the fans, and thus ensure the air circulation on both sides of the middle plate 54 through the plurality of through holes, ensuring the full heat dissipation of the electronic components inside the distribution box.

[0041] Reference Figure 1 and 5 , a detailed description of the embodiment for ensuring the air to flow through a predetermined air duct:

[0042] A rubber strip corresponding to the edges of the top plate 12, the bottom plate 13, the first side plate 21, and the second side plate 22 is fixedly connected to the door panel 31. Thus, the edges of the door panel 31 and the top plate 12, the bottom plate 13, the first side plate 21, and the second side plate 22 can be sealed by the rubber strip, preventing air from flowing at the joints of the door panel 31 and the top plate 12, the bottom plate 13, the first side plate 21, and the second side plate 22. When a fan is installed on the power distribution box to circulate the air in the predetermined air duct, it will affect the guiding effect of the fan on the air and the heat dissipation effect of the electronic components in the power distribution box.

[0043] Reference Figure 1 、 3 、5, and 6 to detail the embodiments of limiting the rotation of the first side plate 21 and the second side plate 22:

[0044] The upper end surfaces of the top plate 12, the first side plate 21, the second side plate 22, and the door panel 31 are in the same plane, and the lower end surfaces of the bottom plate 13, the first side plate 21, the second side plate 22, and the door panel 31 are in the same plane.

[0045] Thus, the rotating first side plate 21 and the second side plate 22 can be limited by the top plate 12 and the bottom plate 13, preventing the first side plate 21 and the second side plate 22 from rotating into the space of the back plate 11, the top plate 12, and the bottom plate 13 during rotation, causing collisions of electronic components and damage to the electronic components. It can protect the electronic components. At the same time, the top plate 12 and the bottom plate 13 can also limit the rotation of the rotating door panel 31, preventing the door panel 31 from rotating into the space in the middle of the back plate 11, the top plate 12, and the bottom plate 13, and preventing collisions of electronic components and damage, affecting the use of the electronic components.

[0046] Reference Figure 3 to detail the embodiments of the sealing at the joints of the first side plate 21 and the second side plate 22:

[0047] Rubber strips corresponding to the back plate 11, the top plate 12, and the bottom plate 13 are provided on the first side plate 21 and the second side plate 22. Thus, when the first side plate 21 and the second side plate 22 are rotated to fit the back plate 11, the top plate 12, and the bottom plate 13, the rubber strips can be squeezed by the first side plate 21 and the second side plate 22 to seal the joints of the first side plate 21 and the second side plate 22 with the back plate 11, the top plate 12, and the bottom plate 13, preventing the air in the power distribution box from escaping everywhere, affecting the air duct for guiding the air flow by the fan installed on the power distribution box, and affecting the heat dissipation effect of the electronic components in the power distribution box.

[0048] Reference Figure 2 and 3 to detail the embodiments of ensuring that the ferrule 24 can be stuck on the clamping post 15 for positioning the first side plate 21 and the second side plate 22:

[0049] The ferrule 24 is made of an elastic material and is provided with an opening. Thus, when the first side plate 21 and the second side plate 22 rotate, the opening of the ferrule 24 can undergo elastic deformation and be stuck on the clamping post 15, thereby realizing the positioning of the first side plate 21 and the second side plate 22.
