In summary, the environmentally friendly and energy-saving electric energy meter box described in the present invention has significant innovations and advantages in fire prevention and fire extinguishing, and is expected to provide a safer and more reliable solution for the field of electric energy metering in practical applications.

[0032] Furthermore, it also includes a head valve body 5, which is arranged at the nozzle 402, has a rotating valve stem 501 and a first pin hole 502, and the first pin hole 502 is located on one side of the rotating valve stem 501; a pressure handle 6 is arranged on the rotating valve stem 501, and the pressure handle 6 has a second pin hole 601; one end of the first elastic member 7 is connected to the fire extinguisher 4, and the other end is connected to the pressure handle 6, providing a force for the pressure handle 6 to rotate to open the head valve body 5; the opening pin 8 is slidably arranged in the first pin hole 502, and extends into the second pin hole 601.

[0033] In this embodiment, the electric energy meter box further includes a valve body 5, a pressure handle 6, a first elastic member 7 and an opening pin 8. The valve body 5 is arranged at the nozzle 402 of the fire extinguisher 4, and is provided with a rotating valve stem 501 and a first pin hole 502; the pressure handle 6 is arranged on the rotating valve stem 501 and has a second pin hole 601; one end of the first elastic member 7 is connected to the fire extinguisher 4, and the other end is connected to the pressure handle 6; the opening pin 8 is slidably arranged in the first pin hole 502 and extends into the second pin hole 601.

[0034] In this embodiment, the head valve body 5 is installed at the nozzle 402 of the fire extinguisher 4, which plays a key role in controlling the ejection of the fire extinguishing agent. The opening and closing operations of the fire extinguisher 4 are realized by rotating the valve stem 501 and cooperating with the pressure handle 6. Innovation: Accurately control the release of the fire extinguishing agent to ensure that the fire extinguishing agent can be ejected quickly and effectively when fire extinguishing is required, thereby improving the timeliness and accuracy of fire extinguishing. The function of the pressure handle 6: It is arranged on the rotating valve stem 501, and through operations such as rotation or pressing, it cooperates with the head valve body 5 to open the fire extinguisher 4 and eject the fire extinguishing agent. It provides a convenient way to operate the fire extinguisher 4, so that the fire extinguishing device can be quickly started in an emergency. One end of the first elastic member 7 is connected to the fire extinguisher 4, and the other end is connected to the pressure handle 6, which provides the pressure handle 6 with a force to rotate so that the head valve body 5 is opened. Under normal conditions, the pressure handle 6 is kept in a closed position. When fire extinguishing is required, the force of the first elastic member 7 pulls the pressure handle 6 to open the head valve body 5 for fire extinguishing. Thereby ensuring that the fire extinguisher 4 is in a closed state when not in use, improving safety. At the same time, when a fire needs to be extinguished, the fire extinguisher 4 can be quickly opened with the help of the force of the first elastic member 7, improving the response speed of fire extinguishing.

[0035] In this embodiment, the opening pin 8 is slidably disposed in the first pin hole 502 and extends into the second pin hole 601, playing the role of locking the pressure handle 6 to prevent the fire extinguisher 4 from being accidentally opened due to misoperation. When it is necessary to extinguish a fire, the opening pin 8 is pulled out to release the lock on the pressure handle 6. The safety of the fire extinguisher 4 is increased, unnecessary release of the fire extinguishing agent due to misoperation is avoided, and the reliability of the electric energy meter box is improved.

[0036] In this embodiment, fire extinguishing can be precisely controlled: the cooperation between the valve body 5 and the pressure handle 6 can realize precise control of the spraying of the fire extinguishing agent, ensuring the maximum fire extinguishing effect. Quick response to fire extinguishing: the setting of the first elastic member 7 enables the fire extinguisher 4 to be opened quickly in an emergency, thereby improving the response speed of fire extinguishing and reducing the losses caused by the fire. Safe and reliable: the locking function of the opening pin 8 effectively prevents misoperation and improves the safety and reliability of the electric energy meter box.

[0037] In summary, the newly added components realize accurate control, rapid response and safe and reliable operation of the fire extinguisher 4, providing a stronger guarantee for the safe operation of the electric energy metering box.

[0038] Furthermore, it also includes a tension spring 9, one end of which is connected to the opening pin 8 and is used to provide a force for pulling the opening pin 8 out of the second pin hole 601; a rubber puller 10, one end of which is used to act with the opening pin 8 and is used to provide a force for pulling the opening pin 8 into the second pin hole 601, and the rubber puller 10 is used to be burned so that the opening pin 8 is pulled out of the second pin hole 601.

[0039] In this embodiment, a tension spring 9 and a rubber puller 10 are further introduced. One end of the tension spring 9 is connected to the opening pin 8, and its function is to provide a force for the opening pin 8 to be pulled out from the second pin hole 601. One end of the rubber puller 10 also acts on the opening pin 8, and its function is to provide a force for the opening pin 8 to be pulled into the second pin hole 601, and when encountering a specific situation, the rubber puller 10 will be burned off, so that the opening pin 8 is pulled out from the second pin hole 601, so that when a fire occurs in the metering box, the fire can be quickly extinguished.

[0040] In this embodiment, the tension spring 9 is always in a stretched state, exerting an outward pulling force on the opening pin 8. When the fire extinguisher needs to be opened, this pulling force can help the opening pin 8 to be quickly pulled out from the second pin hole 601, thereby releasing the lock on the pressure handle 6, so that the pressure handle 6 opens the valve body 5 under the action of the first elastic member 7, allowing the fire extinguisher to start extinguishing the fire. A reliable opening force source is provided to ensure that the opening pin 8 can respond quickly in an emergency, thereby improving the timeliness of fire extinguishing.

[0041] In this embodiment, in a normal state, the rubber puller 10 applies a pulling force to the opening pin 8 to keep the opening pin 8 in the second pin hole 601, thereby locking the pressure handle 6 and preventing the fire extinguisher from being accidentally started. When a fire occurs inside the electric energy meter box and the temperature rises to a certain level, the rubber puller 10 will be burned out. At this time, the tension of the tension spring 9 will play a leading role, quickly pulling the opening pin 8 out of the second pin hole 601 and starting the fire extinguishing procedure. On the one hand, under normal circumstances, the safety of the fire extinguisher is ensured to avoid misoperation; on the other hand, when a fire occurs, the fire extinguishing device can be automatically triggered without manual intervention, thereby improving the reliability and timeliness of fire extinguishing.

[0042] In this embodiment, the automatic fire extinguishing function: through the synergistic effect of the tension spring 9 and the rubber puller 10, the automatic fire extinguishing function of the electric energy meter box in the event of a fire is realized. When a fire occurs, the rubber puller 10 is burned out, and the tension spring 9 quickly pulls the opening pin 8 to start the fire extinguisher to extinguish the fire, which greatly improves the efficiency and timeliness of fire extinguishing. Safe and reliable: Under normal circumstances, the rubber puller 10 can effectively lock the fire extinguisher to prevent accidental start-up, thereby improving the safety of the electric energy meter box. At the same time, the presence of the tension spring 9 also ensures that the fire extinguishing device can be quickly started when fire extinguishing is needed, thereby improving the reliability of the equipment. Strong adaptability: This design can adapt to different ambient temperatures and fire conditions, and has strong adaptability and stability. Whether in a high temperature environment or in the event of a sudden fire, it can effectively play a fire extinguishing role.

[0043] In summary, the addition of the tension spring 9 and the rubber pull piece 10 further improves the fire extinguishing function of the environmentally friendly and energy-saving electric energy metering box, improves the safety and reliability of the equipment, and has important practical application value.

[0044] Furthermore, the first hanging joint 11 and the second hanging joint 12 are provided at the other ends of the tension spring 9 and the rubber pull member 10, respectively. The first hanging ring 13 and the second hanging ring 14 are both arranged on the fire extinguisher 4 or on the box 1 , the first hanging joint 11 is used for hanging on the first hanging ring 13 , and the second hanging joint 12 is used for hanging on the second hanging ring 14 .

[0045] In this embodiment, a first hanging joint 11, a second hanging joint 12, a first hanging ring 13 and a second hanging ring 14 are designed. The first hanging joint 11 and the second hanging joint 12 are respectively arranged at the other ends of the tension spring 9 and the rubber pull member 10, the first hanging ring 13 and the second hanging ring 14 are arranged on the fire extinguisher 4 or the box 1, the first hanging joint 11 is hung on the first hanging ring 13, and the second hanging joint 12 is hung on the second hanging ring 14.

[0046] In this embodiment, the first hanging joint 11 and the second hanging joint 12 are key components for connecting the tension spring 9 and the rubber puller 10 with the hanging ring, ensuring that the tension spring and the rubber puller can function stably. The first hanging joint 11 transmits the tension of the tension spring to the first hanging ring, and the second hanging joint 12 transmits the tension of the rubber puller to the second hanging ring. It is easy to install and disassemble, and convenient to operate during maintenance and replacement of parts. At the same time, the design of the hanging joint can ensure the firmness of the connection and prevent it from falling off during use.

[0047] In this embodiment, the first hanging ring 13 and the second hanging ring 14 provide a hanging position so that the tension spring 9 and the rubber puller 10 can be connected to the fire extinguisher 4 or the box 1. The first hanging ring 13 receives the tension of the tension spring transmitted by the first hanging joint 11, and the second hanging ring 14 receives the tension of the rubber puller transmitted by the second hanging joint 12. It can be set at different positions according to actual needs, which improves the flexibility of the design. The hanging ring has a simple structure and high reliability, and can withstand a certain tension, ensuring that the effect of the tension spring and the rubber puller can be effectively transmitted to the fire extinguisher.

[0048] In this embodiment, the connection stability is enhanced: through the cooperation of the hanging joint and the hanging ring, the connection between the tension spring 9 and the rubber puller 10 and the fire extinguisher 4 or the box 1 is more stable and reliable. When a fire occurs, it can ensure that the tension spring and the rubber puller can play their role accurately, and the fire extinguisher can be started to extinguish the fire. Convenient maintenance and replacement: The design of the hanging joint and the hanging ring makes the maintenance and replacement of components more convenient and quick. When the tension spring or rubber puller needs to be replaced or maintained, it is only necessary to remove the hanging joint from the hanging ring to operate, which improves maintenance efficiency. Improve design flexibility: The position of the hanging ring can be set according to actual conditions, which increases the flexibility of the design. The appropriate hanging ring position can be selected according to factors such as the installation position of the fire extinguisher and the structure of the box, making the design of the entire electricity meter box more reasonable and efficient.

[0049] In summary, the addition of the first hanging joint 11, the second hanging joint 12, the first hanging ring 13 and the second hanging ring 14 further improves the structure of the environmentally friendly and energy-saving electric energy metering box and improves its performance and reliability.

[0050] Furthermore, the opening pin 8 has a strip hole 801 and also includes an insertion rod 15, which is inserted into the strip hole 801. There are two rubber pullers 10, and one end of the two rubber pullers 10 is respectively connected to the two ends of the insertion rod 15. After one of the rubber pullers 10 is burned, the insertion rod 15 swings in the strip hole 801 and is pulled by the other rubber puller 10.

[0051] In this embodiment, the structural features of the opening pin 8 are designed and the insertion rod 15 is newly added. The opening pin 8 has a strip hole 801, and the insertion rod 15 is inserted into the strip hole 801. At the same time, there are two rubber pull pieces 10, and one end of the two rubber pull pieces 10 is respectively connected to the two ends of the insertion rod 15. When one of the rubber pull pieces 10 is burned off, the insertion rod 15 swings in the strip hole 801 and is pulled by the other rubber pull piece 10.

[0052] In this embodiment, the strip hole 801 of the opening pin 8 provides a space for installation and movement of the insertion rod 15. The design of the strip hole 801 allows the insertion rod 15 to swing to a certain extent therein, so that the opening pin 8 can be opened after one of the two rubber pull pieces 10 is burned off.

[0053] In this embodiment, the plug rod 15 is an intermediate component connecting the two rubber pull members 10. The plug rod 15 plays a key role in transmitting tension and realizing specific actions in the system. When one rubber pull member 10 is burned off, the plug rod 15 swings in the strip hole 801, so that the other rubber pull member 10 can slide out of the strip hole 801 following the plug rod 15, thereby ensuring the start of fire extinguishing, so that after one of the two rubber pull members 10 is burned off, the start of fire extinguishing can be realized.

[0054] Furthermore, the opening of the second pin hole 601 faces the insertion rod 15 .

[0055] In this embodiment, when the opening pin 8 is matched with the pressure handle 6 through the second pin hole 601, the opening of the second pin hole 601 is directed toward the insertion rod 15, so that the opening pin 8 is subjected to more uniform and direct force when subjected to the pulling force of the rubber puller 10 and the insertion rod 15. Such a design helps to ensure that the opening pin 8 can be stably inserted into the second pin hole 601 under normal conditions, thereby improving the stability of the locked state of the fire extinguisher. At the same time, the accurate opening direction can reduce the possibility of misalignment between the opening pin 8 and the second pin hole 601 due to external interference or loose components, further enhancing the reliability of the system.

[0056] In this embodiment, when a fire occurs, after one of the rubber pull members 10 is burned off, the insertion rod 15 swings in the strip hole 801 and is pulled by the other rubber pull member 10. At this time, since the opening of the second pin hole 601 faces the insertion rod 15, the opening pin 8 can respond to the change of tension more quickly and is more easily pulled out of the second pin hole 601. This design can speed up the activation speed of the fire extinguisher and improve the timeliness and effectiveness of fire extinguishing.

[0057] Furthermore, the end of the opening pin 8 close to the second pin hole 601 has a circular slot 802, and further includes: The positioning bead 16 is disposed in the second pin hole 601 , and the head of the positioning bead 16 extends into the circular slot 802 .

[0058] In this embodiment, the structural features of the opening pin 8 are designed and the positioning bead 16 is newly added. The opening pin 8 has a circular groove 802 at one end close to the second pin hole 601 , and the positioning bead 16 is arranged in the second pin hole 601 and partially extends into the circular groove 802 .

[0059] In this embodiment, the circular card slot 802 provides a position for the positioning bead 16 to engage, thereby enhancing the connection stability between the opening pin 8 and the pressure handle 6. When the opening pin 8 is inserted into the second pin hole 601, the positioning bead 16 is inserted into the circular card slot 802, which can prevent the opening pin 8 from accidentally coming out, and ensure that the fire extinguisher is in a locked state under normal conditions. The reliability and safety of the connection are improved. The design of the circular card slot 802 makes the connection between the opening pin 8 and the pressure handle 6 more secure, reducing the possibility of the opening pin 8 loosening due to external vibration or other factors.

[0060] In this embodiment, the positioning bead 16 disposed in the second pin hole 601 plays a role in positioning and locking. When the opening pin 8 is inserted into the second pin hole 601, the positioning bead 16 partially extends into the circular slot 802, further fixing the position of the opening pin 8 to prevent it from moving under unexpected circumstances. When it is necessary to pull out the opening pin 8 to start the fire extinguisher, the positioning bead 16 can be pulled out of the circular slot 802 under the action of a certain external force, and will not hinder the movement of the opening pin 8. The stability and reliability of the system are increased. The design of the positioning bead 16 makes the locking of the opening pin 8 more reliable, and at the same time, it can be smoothly unlocked when the fire extinguisher needs to be started, thereby improving the response speed and safety of the system.

[0061] Furthermore, there are two positioning beads 16 , which are respectively located on both sides of the opening pin 8 .

[0062] In this embodiment, two positioning beads 16 are respectively located on both sides of the opening pin 8, and the opening pin 8 can be positioned and fixed from two different directions. This symmetrical layout can make the opening pin 8 receive a more uniform force after being inserted into the second pin hole 601, thereby improving the stability of the connection. Compared with a single positioning bead, two positioning beads can better resist the interference of external forces, reduce the movement or loosening of the opening pin 8 under unexpected circumstances, and ensure that the fire extinguisher is always in a reliable locked state under normal conditions.

[0063] The arrangement of the two positioning beads 16 can make the insertion and extraction process of the opening pin 8 smoother and more stable. When inserting the opening pin 8, the positioning beads on both sides can cooperate with the circular slot 802 at the same time, guiding the opening pin 8 to accurately insert into the second pin hole 601, reducing the difficulty and error of operation. When extracting the opening pin 8, the synchronous removal of the two positioning beads can also make the operation easier and more reliable.

[0064] Furthermore, it also includes a safety clip 17, one end of which is hingedly set on the valve body 5 of the head, and the other end has a bayonet 1701. After the safety clip 17 is rotated, the end of the insertion rod 15 is inserted into the bayonet 1701. There are two safety clips 17, which are symmetrically arranged on both sides of the valve body 5 of the head.

[0065] In this embodiment, a safety clip 17 is newly added. One end of the safety clip 17 is hingedly arranged on the valve body 5 of the device head, and the other end has a bayonet 1701. After the safety clip 17 is rotated, the end of the insertion rod 15 can be inserted into the bayonet 1701, and there are two safety clips 17, which are symmetrically arranged on both sides of the valve body 5 of the device head.

[0066] In this embodiment, the safety card 17 serves as an additional safety mechanism. The safety card 17 can clamp the plug rod 15 through the bayonet 1701 before installation, further preventing the opening pin 8 from accidentally falling out, thereby ensuring that the fire extinguisher will not be activated by mistake. When the fire extinguisher is installed, the safety card 17 can be turned open to release the restriction on the plug rod 15 to ensure that the fire extinguisher can extinguish the fire in time after a fire occurs. The safety and reliability of the system are increased. The safety card 17 provides double insurance, which can effectively prevent the fire extinguisher from accidentally starting even if the positioning bead 16 fails. At the same time, the two symmetrically arranged safety cards 17 can fix the plug rod 15 from both sides at the same time, thereby improving the stability of the fixation.

[0067] In this embodiment, the bayonet 1701 cooperates with the plug rod 15 to achieve the clamping and fixing of the plug rod 15. When the safety clamp 17 is rotated to a suitable position, the bayonet 1701 can tightly clamp the plug rod 15 to prevent it from moving. The safety clamp 17 is ensured to effectively fix the plug rod 15, thereby improving the safety of the system. The shape and size of the bayonet 1701 can be designed according to the specifications of the plug rod 15 to ensure the firmness of the clamping.

[0068] In this embodiment, the safety is improved: the setting of the safety card 17 provides additional safety protection before the fire extinguishing system of the electric energy meter box is installed, reducing the risk of the fire extinguisher being accidentally started. Enhanced stability: The two symmetrically arranged safety cards 17 can fix the plug rod 15 from both sides at the same time, improving the stability of the fixation and ensuring that the fire extinguisher can maintain a reliable locked state before being installed in the electric energy meter box. Easy to operate: After the fire extinguisher is installed in the electric energy meter box, you only need to turn the safety card 17 to open it, which is simple and convenient to operate. The newly added safety card 17 further improves the design of the environmentally friendly and energy-saving electric energy meter box and improves its safety and reliability.
