Description

Technical Field

[0001] The present invention relates to the technical field of electric meter boxes, and specifically, to electric meter boxes. Background Art

[0002] An electric meter box is a box used to install and protect electric meters and related electrical equipment. It is usually used in residential, commercial or industrial buildings to supply electricity to the building and perform metering. The electric meter box usually contains equipment such as electric meters, circuit breakers, and terminal blocks, which play roles such as electric power metering, safety protection, and current control. According to different requirements, the electric meter box may also be equipped with additional equipment such as switches and leakage protectors.

[0003] The existing installation of electric meter boxes usually adopts the traditional rivet fixing method or screw fixing method, connecting the bottom plate of the electric meter box to the box wall through a plastic seat or aluminum profile, and the bracket is attached to the box wall through rivets or screws.

[0004] This fixing method requires more manual operation steps during assembly, and due to the limited fitting accuracy of some components, uneven stress may occur during the installation process. Especially under external forces, the rivets or screws may become loose due to vibration or long-term use, thereby affecting the stability of the overall structure of the electric meter box.

[0016] The working principle and beneficial effects of the present invention are as follows:

[0017] The working process of this embodiment: When the meter box needs to close and seal the first box door, rotate the first box door so that the first limiting pin turns to abut against the limiting block, and then push the first box door towards the box body. The card on the box door is inserted into the limiting hole of the second mounting member, pushing the second limiting member downward. At this time, the clamping end on the clamping member is inserted into the clamping hole in the card. Under the push of the second limiting spring on the control end of the clamping member, it is ensured that the card cannot be pulled out after being locked, completing the sealing of the meter box; When the meter box is disassembled during normal operation of the motor, start the driving motor. The screw rod rotates to drive the first abutting member to move, pushing the control member downward. At this time, the clamping member rotates away from the card, and the first box door can be opened; When the motor is damaged and the meter box needs to be disassembled, open the safe, press down the second abutting member, so that the second abutting member pushes the clamping member to rotate away from the card. At this time, the first box door can be opened.

[0018] In this embodiment, a working cavity is provided inside the box body. The meter is installed and fixed through the first insulating bracket and the second insulating bracket. Through the cooperation of the first positioning groove and the first positioning rib, it replaces the prior art of directly connecting the first insulating bracket, the second insulating bracket and the box body through bolts. Not only does it make the installation and positioning of the first insulating bracket, the second insulating bracket and the box body faster, but also due to the increased connection constraint between the first insulating bracket, the second insulating bracket and the box body, the meter box is installed more firmly and stably, with strong practicability.

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts fall within the scope of protection of the present invention.

[0033] As Figures 1 to 10 shown, an electric meter box is proposed in this embodiment, and its structure includes a box body 1.

[0034] In this embodiment, the first box door 2 is rotatably connected to the box body 1. The working cavity 11 is arranged inside the box body 1. The first insulating bracket 31 and the second insulating bracket 32 are arranged inside the working cavity 11. In this embodiment, both the first insulating bracket 31 and the second insulating bracket are used to install the electricity meter. A number of first positioning ribs 111 are arranged inside the working cavity 11. A number of first positioning grooves 311 are arranged on the first insulating bracket 31 and the second insulating bracket 32. The first positioning ribs 111 and the first positioning grooves 311 correspond to each other one by one. The first positioning ribs 111 are inserted into the first positioning grooves 311. Both the first insulating bracket 31 and the second insulating bracket 32 are fixedly connected to the working cavity 11 by bolts. The side brackets 33 are arranged on the first insulating bracket 31 and the second insulating bracket 32. The side brackets 33 are made of elastic materials. In this embodiment, through the cooperation of the first positioning ribs 111 and the second positioning grooves 312, not only can the positioning be carried out more quickly when the first insulating bracket 31 and the second insulating bracket 32 are installed, which is convenient for the first insulating bracket 31, the second insulating bracket 32 and the box body 1 to be fixedly connected by bolts, but also the constraint between the first insulating bracket 31, the second insulating bracket 32 and the box body 1 is increased, making the internal parts of the box body 1 more firm and reliable.

[0035] This embodiment further includes positioning pins 331. In this embodiment, positioning card corners 313 are arranged on the side brackets 33. The positioning pins 331 and the positioning card corners 313 correspond to each other one by one. The positioning pins 331 are clamped with the positioning card corners 313. Both the first insulating bracket 31 and the second insulating bracket 32 are fixedly connected to the side brackets 33 by bolts. In this embodiment, a plastic seat can be arranged inside the box body 1. The first insulating bracket 31, the second insulating bracket 32 and the side brackets 33 are all fixedly connected to the box body 1 through the plastic seat. In the prior art, the electricity meter is installed and fixed on the first insulating bracket 31 and the second insulating bracket 32. The two sides of the electricity meter are respectively attached to the wall of the box body 1 and riveted, resulting in dryness when cooperating with the lid, affecting the use performance of the product. Now, the structure has been changed. The first insulating bracket, the second insulating bracket and the plastic seat are respectively provided with card corner limits, and then they are attached to the bottom surface of the box body 1 and fixed with the original installation screws, improving the consistency of the brackets and reducing the assembly process. When the electricity meter is installed inside the box body 1, the electricity meter box is installed and fixed inside the box body 1 through the limit abutment of the side brackets 33 and the first box door 2.

[0036] In this embodiment, the wiring clip 4 is arranged at both ends of the first insulating bracket 31. The wiring bracket 41 is arranged between the wiring clip 4 and the first insulating bracket 31. A number of second positioning grooves 312 are arranged on the first insulating bracket 31, and second positioning ribs 411 are arranged on the wiring bracket 41. In this embodiment, through the cooperation of the second positioning grooves 312 and the second positioning ribs 411, when the wiring bracket 41 is installed on the first insulating bracket 31, it is pre-positioned through the second positioning ribs 411 and the second positioning grooves 312, making the installation of the wiring bracket 41 smoother and more accurate. The second positioning ribs 411 are inserted into the second positioning grooves 312. A number of positioning posts 412 are arranged on the wiring bracket 41, and each positioning post 412 abuts against the wiring clip 4. In this embodiment, the preset installation position of the wiring clip 4 is determined through the positioning posts 412, making the installation of the wiring clip 4 smoother and more accurate. The wiring clip 4, the first insulating bracket 31 and the wiring bracket 41 are fixedly connected by bolts, and the structures of the first insulating bracket 31 and the second insulating bracket 32 are the same. The wiring clip 4 in the meter box is mainly used to connect and fix the cable line. The traditional reinforcing clip 42 is designed on the periphery of the wiring clip 4, and its structure can only play a limiting role and has no rebounding effect. Or there is a stainless steel wire inside the wiring clip 4, but it cannot be fixed effectively and is prone to skewing and falling. The currently designed reinforcing clip 42 is similar in shape to the wiring clip 4 and is placed inside the wiring clip 4 and fixed with the original screws. It can not only play a role in restricting the force for the clip to open, but also play a role in rebounding the clip. In this embodiment, the meter is installed in the box body 1, and the connection piece on the meter is inserted and fixed on the wiring clip 4 to ensure power supply to the meter.

[0037] In this embodiment, the reinforcing clip 42 is arranged inside the wiring clip 4. The reinforcing clip 42 and the wiring clip 4 are fixedly connected by bolts, and the reinforcing clip 42 abuts against the wiring clip 4. The traditional reinforcing clip 42 is designed on the periphery of the wiring clip 4, and its structure can only play a limiting role and cannot provide a rebounding force. If a stainless steel wire is placed inside the wiring clip 4, although it can provide certain support, it cannot be fixed effectively and is prone to skewing or falling of the clip. The currently designed reinforcing clip 42 is similar in shape to the wiring clip 4, is placed inside the wiring clip 4, and is fixed with the original screws. In this way, it can not only effectively restrict the force for the clip to open, but also provide a rebounding force to ensure the stability and fixing effect of the clip. In this embodiment, double-headed screws can be used to connect the wiring clip 4 and the reinforcing clip 42 to increase the locking effect of the wiring clip 4 and the reinforcing clip 42 and reduce the temperature rise caused by loosening.

[0038] The traditional reinforcing clip 42 is designed on the periphery of the wiring clip 4, and its structure can only play a limiting role and has no rebounding effect. Or there is a stainless steel wire inside the wiring clip 4, but it cannot be fixed effectively and is prone to skewing and falling. The currently designed reinforcing clip 42 is similar in shape to the wiring clip 4 and is placed inside the wiring clip 4 and fixed with the original screws. It can play a role in restricting the force for the clip to open and also play a role in rebounding the clip.

[0039] The existing electricity meter box is opened by horizontally opening the first box door 2. Although this method can open or close the first box door 2 of the electricity meter box, if the first box door 2 is not closed in time, the following problems may exist: 1. It is easy to cause the door to not close completely due to improper human operation (such as not aligning completely or applying uneven force when pushing or pulling the door), which may affect the sealing performance and safety of the box body 1; 2. It is easy to be interfered by the surrounding environment or objects (such as collision), resulting in the incorrect position of the first box door 2 of the electricity meter, so that it cannot be completely closed or locked. To solve the above problems, the following improvements are proposed in this embodiment.

[0040] A number of first limit members 12 are fixedly connected by screw threads at the top of the working cavity 11. A number of first limit pins 13 are fixedly connected by screw threads on the first box door 2. A second limit pin 14 is rotatably connected to the side of the first limit pin 13 away from the first box door 2. A sliding groove 121 is provided on each first limit member 12. Both the first limit pin 13 and the second limit pin 14 are slidably connected to the sliding groove 121. A limit block 141 is also fixedly connected to the side of the second limit pin 14 close to the first limit pin 13. When the first limit pin 13 enters the sliding groove 121, since the first limit pin 13 enters the sliding groove 121 and cannot rotate, it is convenient for the card 55 in the first box door 2 to accurately enter, ensuring the sealing and locking of the first box door 2; when the first limit pin 13 disengages from the sliding groove 121, the first limit pin 13 can rotate to help open the first box door 2. Through the design of the first limit member 12 in this embodiment, it is ensured that the first box door 2 can finally be pressed into the box body 1 in the vertical direction, ensuring that when the electricity meter is installed, it abuts against the first box door 2 in the vertical direction, and the installation of the electricity meter is more firm and reliable.

[0041] On the side of the first box door 2 away from the first limit pin 13, there are several first mounting parts 5. On the side of the working chamber 11 close to the first mounting parts 5, there are second mounting parts 6. Inside the first mounting parts 5, there is a connection structure for clamping and fixing the first mounting parts 5 and the second mounting parts 6 or separating the first mounting parts 5 and the second mounting parts 6. The connection structure in this embodiment includes a clamping part 62. The clamping part 62 is in a "Z" - shaped structure. The clamping end 621 and the control end 622 are arranged at both ends of the clamping part 62. The control cavity 65 is arranged inside the second mounting part 6. The clamping part 62 is rotatably connected to the control cavity 65. The card 55 is fixedly arranged on the first mounting part 5. A card hole 551 is arranged on the card 55 to ensure that the card 55 cannot be taken out after being clamped out when it penetrates into the limit hole 66. The limit hole 66 is arranged on the second mounting part 6. The card 55 is slidably connected to the limit hole 66. The card hole 551 is clamped with the clamping end 621. The second limiting part 63 and the third limiting part 64 are arranged on the side of the control cavity 65 away from the first mounting part 5. The second limiting part 63 abuts against the clamping part 62. The third limiting part 64 abuts against the control end 622. The control part 611 is arranged at the end of the control cavity 65 away from the third limiting part 64. The control part 611 abuts against the clamping end 621. When the clamping end 621 on the clamping part 62 is clamped with the card hole 551, the clamping part 62 is driven to rotate by the control part 611, so that the clamping part 62 disengages from the card hole 551, facilitating the removal of the card 55.

[0042] In this embodiment, the first limiting groove 633 is arranged inside the control cavity 65. The first sliding block 631 is fixedly arranged on the second limiting part 63. The first sliding block 631 is slidably connected to the first limiting groove 633. The first limiting groove 633 is in a square structure to prevent the first sliding block 631 from rotating and deviating during the sliding process. The first limiting spring 632 is arranged inside the first limiting groove 633. Both ends of the first limiting spring 632 are fixedly connected to the first limiting groove 633 and the first sliding block 631 respectively to ensure that when the card 55 is in the removed state, the second limiting part 63 moves upward, thus replacing the card 55 to abut against the clamping part 62 and preventing interference when the card 55 enters again, resulting in difficulty for the card 55 to enter. The first sliding hole 634 is arranged at the end of the first limiting groove 633 close to the card 55. The first sliding hole 634 is slidably connected to the second limiting part 63. The projection plane of the first sliding hole 634 in the vertical direction falls inside the first limiting groove 633 to prevent the first sliding block 631 from disengaging from the first limiting groove 633. When the card 55 is not inserted into the limit hole 66, the second limiting part 63 is pushed upward under the action of the first limiting spring 632, so that the clamping part 62 rotates in a direction away from the second limiting part 63, facilitating the card 55 to be inserted without the clamping part 62 blocking the insertion path of the card 55. When the card 55 is inserted into the limit hole 66, the card 55 replaces the second limiting part 63 to contact the clamping part 62 until the clamping part 62 enters the card hole 551, making the card 55 unable to be taken out, forming a lock.

[0043] In this embodiment, the second limiting groove 643 is arranged in the control cavity 65. The second sliding block 641 is fixedly arranged and is slidably connected with the second limiting groove 643. The second limiting groove 643 is of a square structure, which is used to prevent the second sliding block 641 from rotating and deviating during the sliding process, making the movement of the second sliding block 641 more stable and reliable. The second limiting spring 642 is arranged in the second limiting groove 643, and both ends of the second limiting spring 642 are fixedly connected with the second limiting groove 643 and the second sliding block 641 respectively, which is used to ensure that the clamping member 62 always contacts with the second limiting member 63 or the card 55, facilitating the clamping end 621 on the clamping member 62 to be clamped into the limit to prevent the box body 1 from being stolen. The second sliding hole 644 is arranged at the end of the second limiting groove 643 close to the clamping member 62, and the second sliding hole 644 is slidably connected with the third limiting member 64. The projection plane of the second sliding hole 644 in the vertical direction falls within the second limiting groove 643, which is used to prevent the second sliding block 641 from detaching from the second limiting groove 643.

[0044] In this embodiment, the control box 61 is arranged in the control cavity 65. The third sliding block 612 is slidably arranged in the control box 61. The third sliding block 612 is fixedly connected with the control member 611. The third limiting spring 613 is sleeved on the control member 611, and both ends of the third limiting spring 613 are fixedly connected with the control box 61 and the third sliding block 612 respectively. In this embodiment, the third limiting spring 613 is adopted to ensure that the control member 611 keeps away from the clamping member 62 without external force, so that the clamping member 62 is clamped into the card hole 551, and the box body 1 is fixedly clamped relative to the second mounting member 6. When the control member 611 moves downward to drive the clamping member 62 to rotate, when the external force is withdrawn, the clamping member 62 will reset under the action of the third limiting spring 613, facilitating the subsequent card 55 to be clamped in after entering.

[0045] This embodiment includes a drive motor 8. The first control structure in this embodiment includes a first abutting member 54. A third sliding hole 56 is provided at the top of the second mounting member 6. The third sliding hole 56 communicates with the control box 61. An installation cavity 51 is provided in the first mounting member 5. A lead screw 53 and a sliding rod 52 are rotatably arranged in the installation cavity 51. Since the rotation stroke of the lead screw 53 is much larger than the movement stroke of the first abutting member 54, controlling the movement of the first abutting member 54 by the lead screw 53 is more accurate and reliable. The first abutting member 54 passes through the third sliding hole 56 and abuts against the control member 611. The first abutting member 54 is threadedly connected to the lead screw 53 and slidably connected to the sliding rod 52. A first gear 81 is fixedly arranged on the output shaft of the drive motor 8, and a second gear 531 is fixedly arranged on the lead screw 53. The first gear 81 and the second gear 531 are meshed. When multiple clamping members 62 are required in the present invention to ensure a more secure installation of the box body 1 and the second mounting member 6, a synchronous belt can be arranged between multiple lead screws to simultaneously synchronously control each first abutting member 54 through the synchronous belt, facilitating the quick disassembly and installation of the box body 1. In this embodiment, the drive motor 8 is used to control the lead screw 53 to drive the first abutting member 54 to control the rotation of the clamping member 62 of the control member 611, replacing manual operation, which is more convenient and reliable. This embodiment can control the drive motor 8 through Bluetooth or an infrared sensor to achieve automatic unlocking of the first door 2.

[0046] The second control structure in this embodiment includes a second abutting member 9. A fourth sliding hole 72 is provided on the first abutting member 54. The second abutting member 9 is slidably connected to the fourth sliding hole 72. A safe 7 is arranged in the working cavity 11, and a second door 71 is arranged on the safe 7. The fourth sliding hole 72 is arranged between the safe 7 and the installation cavity 51. The second abutting member 9 is slidably connected to the fourth sliding hole 72. A first limit bolt 91 is arranged at the end of the second abutting member 9 close to the safe 7, and a second limit bolt 92 is arranged on the side of the second abutting member 9 close to the installation cavity 51.
