[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0031] Refer to Figure 1 - Figure 3, an embodiment provided by the present utility model: a single-phase multi-metering-position metal metering box, including a box body 1. Inside the box body 1, multiple groups of metering meters and some control components are installed, which can perform metering management on electricity. The metering meters and control components are both prior arts and can be realized by those skilled in the art. Since they are prior arts, they will not be described in detail in this case. At the top of the right surface of the box body 1, a chute 4 is provided. On the front surface of the box body 1, a rectangular groove 6 is provided. A protective component is arranged on the inner wall of the rectangular groove 6. An opening and closing component is arranged on the inner wall at the front end of the box body 1. The opening and closing component includes an opening and closing plate 21. Multiple groups of opening and closing plates 21 are provided and are symmetrically arranged with respect to the center line of the box body 1 to ensure that different areas of the box body 1 can be protected. The opening and closing plate 21 slides on the inner wall at the front side of the box body 1. On the left side of the front surface of the opening and closing plate 21, a lock body is provided. The lock body is a prior art and can be used to fix the opening and closing plate 21 to ensure the stability when the opening and closing plate 21 is closed. It can be realized by those skilled in the art, so it will not be described in detail in this case. A rectangular bar 24 is slidably connected to the inner wall at the right end of the opening and closing plate 21. Through the rectangular bar 24, when the opening and closing plate 21 is opened, it can move horizontally to the right by a certain distance and then be flipped open, which can reduce the space occupied in the front side when it is flipped open. A round bar 23 is rotatably connected to the inner wall of the rectangular bar 24. On the upper surface of the round bar 23, a moving block 22 for ensuring the stable movement of the round bar 23 back and forth is fixedly connected. The left end of the moving block 22 is slidably connected to the inner wall of the chute 4.
[0032] Refer to Figure 1 - Figure 2 、 Figure 5 , the protective component includes a rectangular shell 33 for ensuring the stable movement of the protective shell 31. The rear surface of the rectangular shell 33 is slidably connected to the inner wall of the rectangular groove 6. A slider 34 is slidably connected to the inner wall of the rectangular shell 33. The front surface of the slider 34 is fixedly connected to the protective shell 31. The protective shell 31 can protect the lock body and ensure the service life of the lock body. The rear surface of the protective shell 31 contacts the front surface of the box body 1.
[0033] Refer to Figure 2 - Figure 4, the inner wall at the left end of the moving block 22 is elastically connected with a limiting rod 25 through a first spring 26. The first spring 26 always pushes the limiting rod 25 to move leftward through its own elasticity to ensure the stability of the limiting of the limiting rod 25. The limiting rod 25 is slidably connected to the inner wall at the left end of the moving block 22. One end of the first spring 26 is fixedly connected to the inner wall at the left end of the moving block 22, and the other end of the first spring 26 is fixedly connected to the right surface of the limiting rod 25. The left surface of the limiting rod 25 is set as an arc surface. The set arc surface ensures that the limiting rod 25 has a certain limiting stability for the moving block 22, but will not lock it, ensuring that the maintenance worker pulls the opening and closing plate 21. The inner wall of the chute 4 is provided with a plurality of groups of limiting grooves 5. By setting a plurality of groups of limiting grooves 5, one group is the limiting point of the moving block 22 when the opening and closing plate 21 is hidden on the side of the box body 1, and the other group is the limiting point of the moving block 22 when the opening and closing plate 21 is closed. The left surface of the limiting rod 25 contacts the inner wall of the limiting groove 5.
[0034] Refer to Figure 1 - Figure 2 、 Figure 5 , a first sealing groove 27 is opened at the left end of the front surface of the opening and closing plate 21. The first sealing groove 27 is arranged outside the lock body to ensure the protection effect of the sealing frame 32 on the lock body. A second sealing groove 7 is opened on the front surface of the box body 1 above the rectangular groove 6. The second sealing groove 7 is communicated with the first sealing groove 27. A second spring 35 is fixedly connected to the rear surface of the slider 34. The second spring 35 always pulls the slider 34 to move backward through its own elasticity to ensure the sealing effect of the protective shell 31. The rear end of the second spring 35 is fixedly connected to the inner wall of the rectangular shell 33. The protective component further includes a sealing frame 32 for improving the sealing performance of the protective shell 31. The sealing frame 32 is fixedly connected to the rear surface of the protective shell 31. The middle part of the rear surface of the sealing frame 32 contacts the inner wall of the second sealing groove 7, and the right part of the rear surface of the sealing frame 32 contacts the inner wall of the first sealing groove 27.
[0035] Working principle: When it is necessary to open the opening and closing plate 21, the maintenance worker opens the lock through the lock body and then pushes the opening and closing plate 21 to the right. At this time, the rectangular bar 24 slides on the inner wall at the right end of the opening and closing plate 21 until the opening and closing plate 21 can no longer be pushed. Then, the opening and closing plate 21 can be flipped, so that the opening and closing plate 21 drives the rectangular bar 24 to rotate on the outer wall of the round rod 23 until the opening and closing plate 21 is in a vertical state from front to back. Then, the opening and closing plate 21 can be pushed backward. The opening and closing plate 21 will drive the round rod 23 and the moving block 22 to move successively through the rectangular bar 24. During the movement of the moving block 22, the limiting rod 25 will move under the action of the edge of the limiting groove 5, compress the first spring 26 and slide into the inner wall at the left end of the moving block 22. Continue to push the opening and closing plate 21 until the limiting rod 25 overlaps with another set of limiting grooves 5. The first spring 26 will push the limiting rod 25 to reset and insert into the inner wall of another set of limiting grooves 5 through its own elasticity, so that the opening and closing plate 21 is hidden on the side of the box body 1. When it is necessary to close the opening and closing plate 21, just pull the opening and closing plate 21 in the reverse direction. The following structural cooperation method is the same as above, but the movement direction of some structures is opposite to the above.
[0036] In addition, when the opening and closing plate 21 is closed, the rear surface of the protective shell 31 contacts the front surface of the box body 1, so that the middle part of the rear surface of the sealing frame 32 contacts the inner wall of the second sealing groove 7, and the right part of the rear surface of the sealing frame 32 contacts the inner wall of the first sealing groove 27 to protect the lock body on the left side of the front surface of the opening and closing plate 21. When it is necessary to open the lock body, pull the protective shell 31 forward, and the slider 34 slides on the inner wall of the rectangular shell 33 to stretch the second spring 35. Then, push the protective shell 31 downward so that it moves to the bottom end of the front surface of the box body 1, and then the lock body can be opened.
[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
