[0028] The following is combined with Figure 1-6 This application is described in further detail. Embodiment 1

[0029] like Figure 1 , Figure 2 As shown, the modular smart meter box includes a box body 1, a box door 2 and a plurality of meter bodies 3. The box body 1 is provided with a receiving cavity 11 for placing the meter body 3. The receiving cavity 11 is provided with a support plate 12 in the horizontal direction. The meter body 3 is placed on the support plate 12 and is snap-connected with the receiving cavity 11.

[0030] In this embodiment, the box body 1 is a vertical cabinet structure, and there are four box doors 2 distributed along the height direction of the box body 1. The box door 2 is provided with a handle 21. The number of support plates 12 corresponds to the number of box doors 2. Each support plate 12 supports a number of electric meter bodies 3. The back of the electric meter body 3 is snap-connected with the accommodating cavity 11, and the snap-connection can adopt a snap-on structure.

[0031] like Figure 2 , Figure 3 As shown, a limiting rod 4 is slidably arranged inside the accommodating cavity 11 .

[0032] In this embodiment, the limiting rod 4 is arranged along the horizontal direction of the box body 1, and a slide groove 13 is opened along the horizontal direction on the inner side of the accommodating cavity 11. The end of the limiting rod 4 is slidably connected to the slide groove 13, and the limiting rod 4 slides with the accommodating cavity 11 through the slide groove 13.

[0033] like Figure 2 , Figure 3 , Figure 4 As shown, the box door 2 is hinged to the box body 1 through a rotating shaft 5, and a transmission device 6 is provided between the rotating shaft 5 and the limiting rod 4.

[0034] In this embodiment, the rotating shaft 5 includes a main shaft 51 and a plurality of sub-shafts 52. The number of the cabinet doors 2 corresponds to the sub-shafts 52 and the cabinet doors 2 are fixed on the sub-shafts 52. In this embodiment, the cabinet doors 2 and the sub-shafts 52 adopt an integrated structure. As another solution, the door 2 and the sub-axis 52 may also be fixed by welding or screws.

[0035] The split shaft 52 can be installed on the housing 1 via a bearing, and the bearing can support the split shaft 52 .

[0036] A clutch mechanism is provided between the main shaft 51 and the branch shaft 52 .

[0037] Preferably, the sub-shaft 52 is provided with a through hole along its own axial direction, the sub-shafts 52 are coaxially arranged, and the through holes of the sub-shafts 52 are also coaxially arranged, and the main shaft 51 passes through the through holes of the sub-shafts 52 .

[0038] In this embodiment, the clutch mechanism includes a slot 521 and a platform 511 that can be engaged with each other. The slot 521 is opened at the upper end of the branch shaft 52, and the platform 511 is arranged on the outer side of the main shaft 51. The main shaft 51 can slide axially relative to the branch shaft 52, so that the platform 511 is embedded in the slot 521 or slides out of the slot 521.

[0039] Preferably, the upper end of the main shaft 51 passes through the upper end face of the box body 1 and is provided with a knob 512. The user can rotate the main shaft 51 to align the clamping platform 511 of the main shaft 51 with the clamping groove 521 of the sub-shaft 52 and insert it into the clamping groove 521 of the sub-shaft 52, so that the main shaft 51 and the sub-shaft 52 can rotate synchronously. Lift the main shaft 51 upward and rotate it in the reverse direction to extract the clamping platform 511 from the clamping groove 521 of the sub-shaft 52, interrupting the power transmission between the main shaft 51 and the sub-shaft 52.

[0040] As Figure 3 , Figure 5 shown, the transmission device 6 is arranged between the sub-shaft 52 and the limiting rod 4.

[0041] When the box door 2 swings around the main shaft 51 to the closed state, the limiting rod 4 is driven by the transmission device 6 to abut against the side of the electricity meter body 3 close to the box door 2. When the box door 2 swings around the main shaft 51 to the open state, the limiting rod 4 is driven by the transmission device 6 to move away from the electricity meter body 3.

[0042] In this embodiment, the box body 1 is provided with an installation cavity. The transmission device 6 includes a driving wheel, a driven wheel 62, a transmission belt 63, a vertical shaft 64, a driving bevel gear 65, a driven bevel gear 66, a horizontal shaft 67, a circular gear 68 and a rack 69. The driving wheel is coaxially fixed on the sub-shaft 52. The vertical shaft 64 is rotatably arranged in the installation cavity. The driven wheel 62 is coaxially fixed on the vertical shaft 64. The driving wheel is connected to the driven wheel 62 through the transmission belt 63. The driving bevel gear 65 is coaxially fixed on the vertical shaft 64. The horizontal shaft 67 is rotatably arranged in the installation cavity. The driven bevel gear 66 is coaxially fixed on the horizontal shaft 67. The driving bevel gear 65 meshes with the driven bevel gear 66. The circular gear 68 is coaxially fixed on the horizontal shaft 67. The rack 69 is fixed on the limiting rod 4. The circular gear 68 cooperates with the rack 69.

[0043] When the box door 2 is opened, the sub-shaft 52 rotates, driving the vertical shaft 64 to rotate through the driving wheel, the transmission belt 63 and the driven wheel 62. The vertical shaft 64 drives the horizontal shaft 67 to rotate through the driving bevel gear 65 and the driven bevel gear 66. The horizontal shaft 67 drives the limiting rod 4 to slide through the circular gear 68 and the rack 69, abutting against or disengaging from the electricity meter body 3.

[0044] As Figure 2 , Figure 2 shown, the limiting rod 4 includes a rod body 41 and a limiting frame 42. The limiting frame 42 is in a "C" shape and can be attached to both sides of the electricity meter body 3 to form a limit. The rod body 41 is arranged in the horizontal direction. The end of the rod body 41 is connected to the rack 69. An adjusting device 43 is arranged between the limiting frame 42 and the rod body 41. The limiting frame 42 is located between the rod body 41 and the electricity meter body 3. The adjusting device 43 can adjust the distance between the limiting frame 42 and the rod body 41.

[0045] In this embodiment, the adjustment device 43 includes a guide rod 431 and an adjustment bolt 432. One end of the guide rod 431 is fixed on the limit frame 42. The limit rod 4 is provided with a guide hole. The other end of the guide rod 431 passes through the guide hole. The adjustment bolt 432 is rotatably set on the limit rod 4. The limit frame 42 is fixed with an adjustment nut 433 that is threadedly matched with the limit rod 4.

[0046] By rotating the adjusting bolt 432 , the threaded portion of the adjusting bolt 432 cooperates with the adjusting nut 433 , and can drive the limit frame 42 to move, thereby adjusting the position of the limit frame 42 to adapt to the meter body 3 of different thicknesses.

[0047] The working principle of this embodiment is as follows: When the box door 2 swings from the closed state to the open state, the sub-shaft 52 can be driven to rotate, and the sub-shaft 52 can drive the limit rod 4 to move away from the meter body 3 through the transmission device 6, so that the meter body 3 can be quickly removed; The box door 2 swings from the open state to the closed state, which can drive the sub-shaft 52 to rotate. The sub-shaft 52 can drive the limit rod 4 to abut against the meter body 3 through the transmission device 6 to form a limit. When multiple rows of meter bodies 3 need to be replaced, the main shaft 51 and the branch shaft 52 cooperate to achieve power transmission, and when the user opens one door 2, all the doors 2 can be opened synchronously; When a row of electric meter bodies 3 needs to be replaced, the main shaft 51 and the branch shaft 52 cooperate to interrupt the power transmission. When the user opens the corresponding door 2, the other doors 2 will not be opened synchronously. Embodiment 2

[0048] like Figure 6As shown, the difference between this embodiment and the first embodiment is that, in this embodiment, the upper end of the main shaft 51 passes through the upper end surface of the box body 1, and a rotating lifting cylinder 513 is arranged between the main shaft 51 and the fixed plate of the box body 1. The rotating lifting cylinder 513 can be set with a control switch locally, and can also be connected with a remote terminal device such as an APP on a mobile phone. By controlling the rotation and lifting movement of the rotating lifting cylinder 513, the main shaft 51 is lifted and lowered along the axial direction and rotated around the axial direction relative to the branch shaft 52. The control of the remote terminal device can also prevent electricity theft. When the meter box does not need to be repaired, the main shaft 51 is first controlled to rotate so that the card table 511 is aligned with the card slot 521 of the branch shaft 52, and the main shaft 51 is lowered, and the card table 511 is plugged into In the slot 521 of the sub-axis 52, at this time, as long as the remote terminal locks the rotating lifting cylinder 513, the main shaft 51 is in a locked state, and the corresponding sub-axis 52 is also positioned and cannot be opened, and the box door 2 cannot be opened, which plays an anti-theft role; when all the meter bodies 3 need to be inspected, the remote terminal controls the lifting cylinder 513 to rotate, and through the action of the main shaft 51 and the sub-axis 52, all the box doors 2 are opened; when only part of the meter body 3 needs to be inspected, the remote terminal controls the piston rod of the lifting cylinder 513 to extend, so that the main shaft 51 rises, and the card platform 511 of the main shaft 51 is disengaged from the slot 521 of the sub-axis 52, and each sub-axis 52 can rotate freely relative to the main shaft 51 to open the corresponding box door 2.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
