[0004] The meter box may need to be embedded in the wall due to insufficient space to save space. However, the door of the meter box is rotatably connected to the meter box. When opening the door, it may not be able to be opened due to insufficient space, which affects the normal use of the meter box and makes it unable to adapt to narrow venues. Summary of the invention

[0005] In order to improve the problem that the electric meter box cannot adapt to a narrow space, the present application provides an electric meter box.

[0006] The present application provides an electric meter box, which adopts the following technical solution: An electric meter box comprises a box body and a box door, wherein the box door is rotatably connected to the box body, the box door comprises a first rotating door and a second rotating door, the second rotating door is rotatably connected to the box body, and the first rotating door is rotatably connected to the second rotating door.

[0007] By adopting the above technical solution, the second rotating door is rotatably connected to the box body, and the first rotating door is rotatably connected to the second rotating door. When people open the box door, they can rotate the first rotating door to fold the first rotating door onto the second rotating door, so as to reduce the length of the box door and reduce the space occupied by the box door during the rotation process, thereby greatly avoiding the box door being restricted by space when opening, so that the meter box can adapt to narrow venues and improve the applicability of the meter box.

[0008] Optionally, a receiving plate is provided on the box body, a door frame is provided on the receiving plate, and a receiving groove is opened on the door frame for placing the first rotating door and the second rotating door. When the box door blocks the box body, the surface of the door frame away from the box body and the surface of the box door away from the box body are coplanar.

[0009] By adopting the above technical solution, the first rotating door and the second rotating door are placed in the receiving groove, and the surface of the door frame away from the box body and the surface of the box door away from the box body are coplanar. When the box door blocks the box body, the box door can be protected by the receiving plate, reducing the possibility of external debris touching the box door and causing damage to the box door, thereby extending the service life of the box door.

[0010] Optionally, the box body includes a support plate and an extension plate, the support plate is provided with a first support bar, the extension plate is provided with a second support bar, and the first support bar and the second support bar are fixed to each other.

[0011] By adopting the above technical solution, when the overall length of the box is not enough, people can add an extension plate and fix the extension plate to the support plate by means of a first support bar and a second support bar, so as to increase the length of the box and allow the box to meet the different size requirements of users, thereby further improving the adaptability of the meter box.

[0012] Optionally, a moving bar is rotatably connected to the first rotating door, a moving bar is provided with a moving block, a movable groove for sliding the moving bar is provided on the box body, a first through-hole and a second through-hole are provided on the movable groove, both the first through-hole and the second through-hole are provided for the moving bar and the moving block to pass through, when the moving block is located at the first through-hole, the first rotating door blocks the box body, and when the moving block is located at the second through-hole, the first rotating door folds toward the second rotating door.

[0013] By adopting the above technical solution, in case one, the staff pulls the first rotating door to allow the moving bar to pass through the first perforation to achieve the overall opening of the box door; in case two, the staff pulls the second rotating door to allow the moving bar to slide in the movable groove until the moving bar is disengaged from the second perforation, so that the first rotating door is bent toward the second rotating door, so that the staff does not need to manually rotate the first rotating door when the second rotating door is opened, thereby reducing the staff's operating steps; by preventing the moving block from passing through the movable groove, the moving bar can slide stably in the movable groove, reducing the possibility of the moving bar being detached from the box body, and achieving the moving bar being able to stably move to the second perforation.

[0014] Optionally, a clamping strip for covering the first perforation is slidably connected to the box body, and a clamping spring is provided on the clamping strip, and the clamping spring can drive the clamping strip to block the first perforation, and a third magnet is provided on the clamping strip. A clamping rod is slidably connected to the first rotating door, and the clamping rod is provided with a first magnet. When the first magnet attracts the third magnet, the clamping strip does not block the first perforation.

[0015] By adopting the above technical solution, the card rod slides on the first rotating door, so that the first magnet can absorb the third magnet, so that the card rod drives the card strip to move, so that the card strip does not block the first perforation; the card strip is driven to move by the card spring, so that the card strip can block the first perforation, so that the card strip can limit the moving bar from leaving the first perforation, and when the moving bar moves to the second perforation, the first rotating door and the box body form an inclined angle, so that the card strip will not block the second perforation, so that people do not need to limit the first rotating door when pulling the second rotating door, and can pull the second rotating door directly with one hand.

[0016] Optionally, a limit strip is slidably connected to the first rotating door, the clamping rod is located on the sliding path of the limit strip, and a clamping hole for the clamping rod to pass through is provided on the limit strip. When the clamping rod passes through the clamping hole, the first magnet can absorb the third magnet.

[0017] By adopting the above technical solution, the first rotating door is slidably connected to the limit bar. Since the card rod is located on the sliding path of the limit bar, the card rod cannot pass through the card hole, so that the limit bar can limit the card rod from being inserted into the box, and the first magnet in the card rod cannot absorb the third magnet, so that the card rod cannot drive the card bar to move, thereby reducing the possibility of staff accidentally touching the card rod; the card rod passes through the card hole and is inserted into the box, so that the first magnet can absorb the third magnet, so that the card rod can smoothly drive the card bar to move, and the card bar cannot block the first through-hole.

[0018] Optionally, a stop spring is provided on the box body, a stop strip is provided on the stop spring, a stop slope is provided on the limit strip, the distance between the stop slope and the stop strip gradually decreases along the direction from the first rotating door to the second rotating door, the stop slope is located on the moving path of the stop strip, and when the box door is closed, the card hole is not on the moving path of the card rod.

[0019] By adopting the above technical solution, the stop bar is driven to move by the stop spring. Since the stop bevel is located on the moving path of the stop bar, the stop bar can drive the limit bar to move through the stop bevel, so that the card hole is not on the moving path of the card rod, so that the card rod cannot be inserted into the box through the card hole, and the limit bar automatically limits the card rod when the box door is closed, so that the staff does not need to manually drive the limit bar to move, further reducing the possibility of the staff accidentally touching the card rod.

[0020] Optionally, a reset bar is provided on the second rotating door, and the reset bar is located on the rotation path of the stop slope. The length of the clamping rod is longer than the length of the moving bar. When the first rotating door is folded on the second rotating door, the clamping rod can pass through the clamping hole.

[0021] By adopting the above technical scheme, when the first rotating door blocks the second rotating door, the reset bar is located on the rotation path of the stop bevel, so that the reset bar drives the limit bar to slide through the stop bevel, and the card hole in the limit bar moves with the limit bar, so that the card rod can pass through the card hole, and the card rod can stably pass through the card hole. In addition, the length of the card rod is longer than the length of the moving bar. When the box door is closed, the card rod is inserted into the box body before the moving bar, and the card rod drives the card bar to move, so that the card bar does not block the first perforation, so that the moving bar and the moving block can be inserted into the first perforation, so that people do not need to move the card bar when closing the box door, thereby reducing people's operating steps and facilitating people to quickly close the box door.

[0022] Optionally, a card slot is provided on the second rotating door, and a second magnet is provided in the card slot. When the first magnet attracts the second magnet, the card rod passes through the card hole and is inserted into the card slot.

[0023] By adopting the above technical solution, the first magnet attracts the second magnet, and the card rod passes through the card hole and is inserted into the card slot, so that the card rod limits the limit bar, and the staff does not need to move to the side of the first revolving door away from the second revolving door to slide the card rod, which reduces the staff's operation and further simplifies the operation of closing the box door.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: 1. The second rotating door is rotatably connected to the box body, and the first rotating door is rotatably connected to the second rotating door. When people open the box door, they can rotate the first rotating door to fold the first rotating door onto the second rotating door, so as to reduce the length of the box door and reduce the space occupied by the box door during the rotation process, thereby greatly avoiding the box door being restricted by space when opening, so that the meter box can adapt to narrow venues and improve the applicability of the meter box.

[0025] 2. In case one, the staff pulls the first revolving door to allow the moving bar to pass through the first perforation to achieve the overall opening of the box door; in case two, the staff pulls the second revolving door to allow the moving bar to slide in the movable groove until the moving bar is disengaged from the second perforation, so that the first revolving door is bent toward the second revolving door, so that the staff does not need to manually rotate the first revolving door when the second revolving door is opened, thereby reducing the staff's operating steps; by preventing the moving block from passing through the movable groove, the moving bar can slide stably in the movable groove, reducing the possibility of the moving bar being disengaged from the box body, and achieving the moving bar being able to stably move to the second perforation.

The second rotating door 22 is rotatably connected to the box body 1, and the first rotating door 21 is rotatably connected to the second rotating door 22. When the first rotating door 21 and the second rotating door 22 are located in the receiving groove 161, the first rotating door 21 and the second rotating door 22 both block the box body 1. When the box door 2 is opened, the first rotating door 21 can rotate in the direction of the second rotating door 22, that is, the first rotating door 21 is folded onto the second rotating door 22.

[0037] The implementation principle of Example 1 is as follows: people pull the first rotating door 21 until the cabinet door 2 opens to a position where the first rotating door 21 can be folded, and then people rotate the first rotating door 21 to allow the first rotating door 21 to be folded onto the second rotating door 22 .

[0038] Example 2 Reference Figure 6 and Figure 7 The difference between this embodiment and the first embodiment is that a moving bar 3 is rotatably connected to the first rotating door 21, and a moving block 31 is integrally formed on the moving bar 3. The moving bar 3 can be rotated to the side of the first rotating door 21 away from the second rotating door 22.

[0039] Reference Figure 7 and Figure 8 The box body 1 is provided with a movable groove 4, which extends along the length direction of the box body 1. The movable groove 4 allows the moving bar 3 to pass through, and the moving block 31 cannot pass through the movable groove 4. The box body 1 is provided with a first through hole 41 and a second through hole 42 connected to the movable groove 4, and the movable groove 4 is located between the first through hole 41 and the second through hole 42. The first through hole 41 and the second through hole 42 allow the moving bar 3 and the moving block 31 to pass through.

[0040] Reference Figure 6 , Figure 7 and Figure 8 In the first case, people directly pull the first rotating door 21, and the moving bar 3 passes through the first perforation 41, allowing people to open the door 2; in the second case, people directly pull the second rotating door 22, and the moving bar 3 moves from the first perforation 41 to the second perforation 42 through the movable groove 4. At this time, the first rotating door 21 is still connected to the box body 1, that is, the first rotating door 21 is folded toward the direction of the second rotating door 22, until the moving bar 3 is separated from the second perforation 42, so that the first rotating door 21 can be folded onto the second rotating door 22, allowing people to open the door 2.

[0041] Reference Figure 7 and Figure 8The box body 1 is provided with a receiving groove 5 connected to the first through hole 41, and a clamping strip 51 is slidably connected in the receiving groove 5, and the clamping strip 51 extends along the length direction of the box body 1. A clamping spring 52 is fixedly connected to the groove wall of the receiving groove 5 away from the first through hole 41, and the clamping strip 51 is fixedly connected to the end surface of the clamping spring 52. The clamping spring 52 drives the clamping strip 51 to be inserted into the first through hole 41, that is, when the clamping strip 51 is located in the first through hole 41, the clamping spring 52 is in a non-stressed state, and when the clamping strip 51 is completely located in the receiving groove 5, the clamping spring 52 is in a compressed state. When the clamping strip 51 is located in the first through hole 41, the clamping strip 51 restricts the moving block 31 from leaving the first through hole 41.

[0042] Reference Figure 8 and Fig. 9 The first rotating door 21 is provided with a receiving hole 211 , in which a clamping rod 212 is slidably connected. The clamping rod 212 extends along the width direction of the box body 1 , and the length of the clamping rod 212 is greater than the length of the moving bar 3 .

[0043] Reference Figure 8 and Fig.10 The first magnet 213 is fixedly connected to the end surface of the clamping rod 212 facing the box body 1, and the third magnet 53 is fixedly connected to the end surface of the clamping strip 51. When the clamping rod 212 is inserted into the receiving groove 5, the first magnet 213 can attract the third magnet 53, so that the clamping strip 51 is separated from the first through hole 41, so that the moving block 31 and the moving strip 3 can be inserted into the first through hole 41.

[0044] Reference Fig.10 The first rotating door 21 is slidably connected to a limit strip 32, which extends along the length direction of the box body 1. The limit strip 32 is provided with a clamping hole 322 for the clamping rod 212 to pass through, and the limit strip 32 is located on the sliding path of the clamping rod 212. When the clamping hole 322 is located on the sliding path of the clamping rod 212, the clamping rod 212 can pass through the clamping hole 322 and be inserted into the receiving groove 5; when the clamping hole 322 is not located on the sliding path of the clamping rod 212, the limit strip 32 restricts the clamping rod 212 from being inserted into the receiving groove 5.

[0045] Reference Fig. 9 The second rotating door 22 is provided with a limiting groove 221 for the limiting strip 32 to be inserted into. When the limiting strip 32 is inserted into the limiting groove 221, the clamping hole 322 is located on the insertion path of the clamping rod 212, and the limiting strip 32 is located between the first rotating door 21 and the second rotating door 22, so that the first rotating door 21 cannot rotate in the direction of the second rotating door 22.

[0046] Reference Fig.11A stop groove 43 is provided on the box body 1, and a stop spring 431 is provided in the stop groove 43. One end of the stop spring 431 is fixedly connected to the bottom wall of the stop groove 43, and the other end of the stop spring 431 is fixedly connected to a stop bar 432. The stop spring 431 drives the stop bar 432 to protrude from the stop groove 43. When the stop bar 432 protrudes from the stop groove 43, the stop spring 431 is in a non-stressed state. When the stop bar 432 is located in the stop groove 43, the stop spring 431 is in a compressed state.

[0047] Reference Fig. 9 and Fig.11 A stop groove for inserting the stop strip 432 is provided on the surface of the limit strip 32 away from the first rotating door 21, and a stop slope 321 is provided on the bottom wall of the stop groove. When the door 2 is closed, the distance between the stop slope 321 and the box body 1 gradually increases along the direction from the stop slope 321 to the moving strip 3, and the stop slope 321 is located on the protruding path of the stop strip 432. When the door 2 is closed, the stop spring 431 drives the stop strip 432 to abut against the stop slope 321, allowing the limit strip 32 to move, so that the clamping hole 322 is not on the sliding path of the clamping rod 212.

[0048] Reference Fig.10 , Fig.11 and Fig.12 A reset bar 222 is fixedly connected to the surface of the second rotating door 22, and the reset bar 222 is located on the rotation path of the stop slope 321. When the first rotating door 21 is folded on the second rotating door 22, the reset bar 222 abuts against the stop slope 321, and the reset bar 222 drives the limit bar 32 to move through the stop slope 321, so that the clamping hole 322 is located on the sliding path of the clamping rod 212, so that people can use the box door 2 to block the box body 1 later.

[0049] Reference Fig.10 and Fig.12 The second rotating door 22 is provided with a slot 23 for the insertion of the locking rod 212. A second magnet 231 is fixedly connected to the bottom wall of the slot 23, and the second magnet 231 attracts the first magnet 213. When the first rotating door 21 is folded onto the second rotating door 22, the reset bar 222 drives the limit bar 32 to move, so that the locking hole 322 and the slot 23 are aligned. At this time, the second magnet 231 attracts the first magnet 213, so that the locking rod 212 passes through the locking hole 322 and is inserted into the slot 23.

[0050] Reference Figure 7 , Figure 8 and Fig.10 Since the length of the card rod 212 is greater than the length of the moving bar 3, when the card rod 212 passes through the card hole 322 and the first rotating door 21 is closed, the card rod 212 can first be inserted into the accommodating groove 5, so that the card rod 212 can stably prevent the card bar 51 from blocking the first through hole 41.

[0051] The implementation principle of Example 2 is as follows: in case one, people slide the limit strip 32 to insert the limit strip 32 into the limit groove 221, and then move the clamping rod 212 to allow the clamping rod 212 to pass through the clamping hole 322 and be inserted into the accommodating groove 5, so that the first magnet 213 absorbs the third magnet 53, so that the clamping strip 51 does not block the first through hole 41, and the moving block 31 can pass through the first through hole 41, and finally people directly pull the first revolving door 21 or the second revolving door 22.

[0052] In the second situation, people directly open the first revolving door 21. Since the moving block 31 is restricted by the locking bar 51, the moving bar 3 and the moving block 31 are moved from the first through-hole 41 to the second through-hole 42 through the movable groove 4. At this time, the first revolving door 21 can rotate in the direction of the second revolving door 22 until the reset bar 222 drives the limit bar 32 to move, so that the locking hole 322 is aligned with the locking slot 23, and the first magnet 213 absorbs the second magnet 231, so that the locking rod 212 passes through the locking hole 322 and is inserted into the locking slot 23, so that the locking rod 212 is fixed in the locking hole 322, so that the subsequent staff can close the first revolving door 21.
