DETAILED DESCRIPTION

[0021] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] like Figure 1 to Figure 10 As shown, this embodiment proposes an electric meter box, the structure of which includes a box body 1.

[0023] In this embodiment, the first box door 2 is rotatably connected to the box body 1, the working chamber 11 is arranged in the box body 1, the first insulating bracket 31 and the second insulating bracket 32 ​​are arranged in the working chamber 11, and the first insulating bracket 31 and the second insulating bracket 32 ​​in this embodiment are used to install the electric meter. A plurality of first positioning ribs 111 are arranged in the working chamber 11, and a plurality 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, and the first positioning ribs 111 are plugged into the first positioning grooves 311. The first insulating bracket 31 and the second insulating bracket 32 ​​are both fixed to the working chamber 11 by bolts, and the side bracket 33 is arranged on the first insulating bracket 31 and the second insulating bracket 32, and the side bracket 33 is made of elastic material. In this embodiment, the first positioning rib 111 and the second positioning groove 312 cooperate to not only enable faster positioning of the first insulating bracket 31 and the second insulating bracket 32 ​​during installation, and facilitate the fixing of the first insulating bracket 31 and the second insulating bracket 32 ​​to the box body 1 by bolts, but also increase the constraints between the first insulating bracket 31 and the second insulating bracket 32 ​​and the box body 1, making the internal parts of the box body 1 more firm and reliable.

[0024] This embodiment also includes a positioning pin 331. The positioning angle 313 in this embodiment is set on the side bracket 33. The positioning pin 331 corresponds to the positioning angle 313 one by one. The positioning pin 331 is clamped with the positioning angle 313. The first insulating bracket 31 and the second insulating bracket 32 ​​are both connected and fixed to the side bracket 33 by bolts. In this embodiment, a plastic seat can be set in the box 1. The first insulating bracket 31, the second insulating bracket 32 ​​and the side bracket 33 are all connected and fixed to the box 1 through the plastic seat. The prior art is to install and fix the electric meter on the first insulating bracket 31 and the second insulating bracket 32. The two sides of the electric meter are respectively fitted with the wall of the box 1 and fixed with rivets, which causes dryness with the cover and affects the performance of the product. Now the structure has been changed. The first insulating bracket, the second insulating bracket and the plastic seat are respectively fixed with angle limits, and then fit with the bottom surface of the box 1. The original mounting screws are used to fix it, which improves the consistency of the bracket and reduces the assembly process. When the electric meter is installed in the box body 1 , the electric meter box is installed and fixed in the box body 1 through the limiting contact between the side bracket 33 and the first box door 2 .

[0025] The wiring clamp 4 in this embodiment is arranged at both ends of the first insulating bracket 31, the wiring bracket 41 is arranged between the wiring clamp 4 and the first insulating bracket 31, a plurality of second positioning grooves 312 are arranged on the first insulating bracket 31, and a second positioning rib 411 is arranged on the wiring bracket 41. In this embodiment, the second positioning groove 312 and the second positioning rib 411 cooperate, so that when the wiring bracket 41 is installed on the first insulating bracket 31, the second positioning rib 411 and the second positioning groove 312 are pre-positioned, so that the wiring bracket 41 is installed more smoothly and accurately. The second positioning rib 411 is plugged into the second positioning groove 312. A plurality of positioning columns 412 are arranged on the wiring bracket 41, and each positioning column 412 abuts against the wiring clamp 4. In this embodiment, the positioning column 412 presets the installation position of the wiring clamp 4, so that the wiring clamp 4 is installed more smoothly and accurately. The wiring clamp 4, the first insulating bracket 31 and the wiring bracket 41 are fixed by bolts, and the first insulating bracket 31 and the second insulating bracket 32 ​​have the same structure. The wiring clamp 4 in the meter box is mainly used to connect and fix the cable line. The conventional reinforcing clip 42 is designed to be attached to the periphery of the wiring clip 4, and the structure can only play a limiting role without a rebound effect, or the stainless steel wire is attached to the inside of the wiring clip 4, but it cannot be fixed and is easy to tilt and fall. The reinforcing clip 42 designed in the present invention is similar in appearance to the wiring clip 4, and is placed inside the wiring clip 4 and fixed with the original screws, which can not only play a role in limiting the opening of the clip, but also play a role in rebounding the clip. In this embodiment, the electric meter is installed in the box 1, and the wiring piece on the electric meter is plugged and fixed on the wiring clip 4 to ensure that the electric meter is powered.

[0026] The reinforcing clip 42 in this embodiment is arranged in the wiring clamp 4, and the reinforcing clip 42 and the wiring clamp 4 are connected and fixed by bolts, and the reinforcing clip 42 abuts against the wiring clamp 4. The traditional reinforcing clip 42 is designed to be located on the periphery of the wiring clamp 4, and its structure can only play a limiting role and cannot provide resilience. If the stainless steel wire is placed inside the wiring clamp 4, although it can provide a certain support, it cannot be effectively fixed, which can easily cause the clip to tilt or fall off. The reinforcing clip 42 of the current design is similar in appearance to the wiring clamp 4, is placed inside the wiring clamp 4, and is fixed by the original screws. This can not only effectively limit the force of the clamp opening, but also provide resilience to ensure the stability and fixing effect of the clamp. In this embodiment, double-headed screws can be used to connect the wiring clamp 4 and the reinforcing clip 42, increase the locking effect of the wiring clamp 4 and the reinforcing clip 42, and reduce the temperature rise caused by loosening.

[0027] The conventional reinforcing clip 42 is designed to be attached to the periphery of the wiring clip 4, and the structure can only play a limiting role without a rebound effect, or the stainless steel wire is attached to the inside of the wiring clip 4, but it cannot be fixed and is easy to tilt, fall, etc. The reinforcing clip 42 designed now has a similar shape to the wiring clip 4, is placed inside the wiring clip 4 and fixed with the original screws, which can play a role in limiting the force of the clamp opening and also play a role in rebounding the clamp.

[0028] The existing electric meter box is opened by opening the first box door 2 horizontally. Although this method can realize the opening or closing of the first box door 2 of the electric meter box, if the first box door 2 is not closed in time, the following problems may occur: 1. The door cannot be completely closed due to improper human operation (such as not fully aligned or uneven force when sliding the door), which may affect the sealing and safety of the box body 1; 2. It is easy to be disturbed by the surrounding environment or objects (such as collision), resulting in the first box door 2 of the electric meter being misaligned and unable to be completely closed or locked. In order to solve the above problems, this embodiment proposes the following improvements.

[0029] A plurality of first stoppers 12 are fixed to the top of the working chamber 11 by threaded connection, and a plurality of first stopper pins 13 are fixed to the first door 2 by threaded connection. The first stopper pin 13 is rotatably connected to the second stopper pin 14 away from the first door 2. Each first stopper 12 is provided with a sliding groove 121. The first stopper pin 13 and the second stopper pin 14 are both slidably connected to the sliding groove 121. A stopper block 141 is also fixed to the second stopper pin 14 near the first stopper pin 13. When the first stopper pin 13 enters the sliding groove 121, the first stopper pin 13 cannot rotate because it enters the sliding groove 121, which facilitates the accurate entry of the card 55 in the first door 2 and ensures the sealing and locking of the first door 2; when the first stopper pin 13 is out of the sliding groove 121, the first stopper pin 13 can rotate to help the first door 2 open. The design of the first limiting member 12 in this embodiment ensures that the first box door 2 can be finally pressed into the box body 1 in the vertical direction, ensuring that the electric meter is vertically abutted against the first box door 2 during installation, and the installation of the electric meter is more firm and reliable.

[0030] A plurality of first mounting members 5 are provided on the side of the first door 2 away from the first limiting pin 13, a second mounting member 6 is provided on the side of the working chamber 11 close to the first mounting member 5, and a connecting structure for clamping and fixing the first mounting member 5 and the second mounting member 6 or separating the first mounting member 5 and the second mounting member 6 is provided in the first mounting member 5. The connecting structure in this embodiment includes a clamp 62, which is in a "Z"-shaped structure, with a clamping end 621 and a control end 622 arranged at both ends of the clamp 62, a control chamber 65 arranged in the second mounting member 6, the clamp 62 is rotatably connected to the control chamber 65, and a card 55 is fixedly arranged on the first mounting member 5. A clamp hole 551 is arranged on the card 55 to ensure that the card 55 is clamped out after penetrating into the limiting hole 66 and cannot be taken out. The limiting hole 66 is provided on the second mounting member 6, the card 55 is slidably connected with the limiting hole 66, the clamping hole 551 is clamped with the clamping end 621, the second limiting member 63 and the third limiting member 64 are provided on the side of the control cavity 65 away from the first mounting member 5, the second limiting member 63 abuts against the clamping member 62, the third limiting member 64 abuts against the control end 622, the control member 611 is provided at the end of the control cavity 65 away from the third limiting member 64, and the control member 611 abuts against the clamping end 621. When the clamping end 621 on the clamping member 62 is clamped with the clamping hole 551, the clamping member 62 is driven to rotate by the control member 611, so that the clamping member 62 is separated from the clamping hole 551, and the card 55 is convenient to be taken out.

[0031] In this embodiment, the first limit groove 633 is arranged in the control cavity 65, the first sliding block 631 is fixedly arranged on the second limit member 63, the first sliding block 631 is slidingly connected with the first limit groove 633, and the first limit groove 633 is a square structure, which is used to prevent the first sliding block 631 from rotating and deviating during the sliding process. The first limit spring 632 is arranged in the first limit groove 633, and the two ends of the first limit spring 632 are respectively fixedly connected with the first limit groove 633 and the first sliding block 631, which is used to ensure that when the card 55 is in the removal state, the second limit member 63 moves up, thereby replacing the card 55 and contacting the card 62, preventing interference when the card 55 enters again, making it difficult for the card 55 to enter. The first sliding hole 634 is arranged at the end of the first limit groove 633 close to the card 55, and the first sliding hole 634 is slidingly connected with the second limit member 63. The vertical projection of the first sliding hole 634 falls within the first limiting groove 633, which is used to prevent the first sliding block 631 from being separated from the first limiting groove 633. When the card 55 is not inserted into the limiting hole 66, the second limiting member 63 is pushed upward by the first limiting spring 632, so that the card 62 rotates away from the second limiting member 63, so that the card 62 will not hinder the insertion path of the card 55 when the card 55 is inserted. After the card 55 is inserted into the limiting hole 66, the card 55 contacts the card 62 instead of the second limiting member 63 until the card 62 enters the card hole 551, so that the card 55 cannot be taken out, forming a lock.

[0032] In this embodiment, the second limit groove 643 is arranged in the control cavity 65, the second sliding block 641 is fixedly arranged, the second sliding block 641 is slidingly connected with the second limit groove 643, and the second limit groove 643 is a square structure, which is used to prevent the second sliding block 641 from rotating and deviating during the sliding process, so that the movement of the second sliding block 641 is more stable and reliable. The second limit spring 642 is arranged in the second limit groove 643, and the two ends of the second limit spring 642 are respectively fixedly connected with the second limit groove 643 and the second sliding block 641, which is used to ensure that the card 62 always keeps in contact with the second limit member 63 or the card 55, so that the clamping end 621 on the card 62 is conveniently clamped into the limit position to prevent the box 1 from being stolen. The second sliding hole 644 is arranged in the second limit groove 643 near the end of the card 62, and the second sliding hole 644 is slidingly connected with the third limit member 64. The projection surface of the second sliding hole 644 in the vertical direction falls within the second limiting groove 643 , so as to prevent the second sliding block 641 from being separated from the second limiting groove 643 .

[0033] The control box 61 in this embodiment is arranged in the control cavity 65, the third sliding block 612 is slidingly arranged in the control box 61, the third sliding block 612 is fixedly connected to the control member 611, the third limit spring 613 is sleeved on the control member 611, and the two ends of the third limit spring 613 are respectively fixedly connected to the control box 61 and the third sliding block 612. In this embodiment, the third limit spring 613 is used to ensure that the control member 611 remains away from the clamping member 62 when no external force is applied, so that the clamping member 62 is clamped into the clamping hole 551, and the box body 1 remains clamped and fixed 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 removed, the clamping member 62 will be reset under the action of the third limit spring 613, so that the lower card 55 can enter and be clamped.

[0034] This embodiment includes a driving motor 8. The first control structure in this embodiment includes a first abutment member 54, a third sliding hole 56 is arranged at the top of the second mounting member 6, the third sliding hole 56 is communicated with the control box 61, the mounting cavity 51 is arranged in the first mounting member 5, and the screw rod 53 and the sliding rod 52 are rotatably arranged in the mounting cavity 51. Since the rotation stroke of the screw rod 53 is much greater than the movement stroke of the first abutment member 54, it is more accurate and reliable to control the movement of the first abutment member 54 through the screw rod 53. The first abutment member 54 passes through the third sliding hole 56 and abuts against the control member 611, the first abutment member 54 is threadedly connected to the screw rod 53, and the first abutment member 54 is slidably connected to the sliding rod 52. The first gear 81 is fixedly arranged on the output shaft of the driving motor 8, and the second gear 531 is fixedly arranged on the screw rod 53. The first gear 81 is meshed with the second gear 531. When the present invention needs to set multiple clamps 62 to ensure that the box body 1 and the second mounting member 6 are more firmly installed, a synchronous belt can be set between multiple screws, and the synchronous belt can be used to synchronously control each first abutment member 54 at the same time, so as to facilitate the rapid disassembly and installation of the box body 1. In this embodiment, the screw rod 53 is controlled by the driving motor 8 to drive the first abutment member 54 to control the member 611 to rotate the clamp 62, which replaces manual operation and is more convenient and reliable. In this embodiment, the driving motor 8 can be controlled by a Bluetooth or infrared sensor to realize automatic unlocking of the first box door 2.

[0035] The second control structure in this embodiment includes a second abutment 9, a fourth sliding hole 72 is arranged on the first abutment 54, the second abutment 9 is slidingly connected with the fourth sliding hole 72, the safe 7 is arranged in the working chamber 11, the second box door 71 is arranged on the safe 7, the fourth sliding hole 72 is arranged between the safe 7 and the installation chamber 51, the second abutment 9 is slidingly connected with the fourth sliding hole 72, the first limiting bolt 91 is arranged on the second abutment 9 near the end of the safe 7, the second limiting bolt 92 is arranged on the side of the second abutment 9 near the installation chamber 51, the fourth limiting spring 93 is sleeved and arranged on the second abutment 9, and the two ends of the fourth limiting spring 93 are respectively fixedly connected with the first limiting bolt 91 and the safe 7. When the drive motor 8 fails or cannot work normally, the safe 7 can be opened, the second abutment 9 is pressed down, and the card 62 is manually controlled to rotate, so that the card 55 is separated from the card 62, so as to facilitate the disassembly and installation of the box body 1. In this embodiment, a safety lock may be provided on the safe 7, and the second door 71 may be locked by the safety lock to reduce the possibility of the box body 1 being stolen.

[0036] The working process of this embodiment is as follows: when the electric meter box needs to close and seal the first box door 2, the first box door 2 is rotated so that the first limit pin 13 rotates to abut the limit block 141, and then the first box door 2 is pushed toward the box body 1. The card 55 on the box door is inserted into the limit hole 66 of the second mounting member 6, and the second limit member 63 is pushed downward. At this time, the clamping end 621 on the clamp 62 is inserted into the clamp hole 551 in the card 55, and the control end 622 of the clamp 62 is pushed by the second limit spring 642 to ensure that the card 55 is locked. It cannot be pulled out, completing the sealing of the meter box; when the meter box is disassembled when the motor is operating normally, start the drive motor 8, the screw rod 53 rotates to drive the first abutment 54 to move, and pushes the control member 611 to move downward. At this time, the card member 62 rotates away from the card 55, and the first box door 2 can be opened; when the motor is damaged and the meter box needs to be disassembled, open the safe 7, press the second abutment 9 down, so that the second abutment 9 pushes the card member 62 to rotate away from the card 55, and the first box door 2 can be opened.
