Summary of the Invention
[0008] The purpose of this invention is to provide a quick-installation electricity meter box, which has the effect of quickly installing and removing electricity meters.
[0009] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a quick-installation electricity meter box, including an electricity meter and a connector module. The connector module includes a base, a plurality of terminals installed on the base, and a plurality of cover plates corresponding to the plurality of terminals. Each terminal includes a conductor cylinder fixed to the base, a plurality of elastic metal pieces fixed to the end of the conductor cylinder, and an inner rod passing through the conductor cylinder. The surface of the inner rod is provided with an adjustment surface for adjusting the opening or closing of the plurality of elastic metal pieces. The cover plate is fixed to the inner rod. The electricity meter is provided with inlet and outlet holes for the terminals to be inserted.
[0010] By adopting the above technical solution, this invention designs a connector module in which the terminals replace the inlet and outlet wires of the electricity meter. This not only stabilizes the electricity meter but also clearly marks the inlet and outlet wire positions, ensuring the accuracy of the electricity meter installation. When disassembling the electricity meter, pulling down the cover plate causes the inner rod to descend, bringing the elastic metal sheets closer together and reducing the force between the terminals and the electricity meter's inlet and outlet holes, making it easier to remove the electricity meter directly. When installing the electricity meter, align the inlet and outlet holes of the new electricity meter with the terminals and insert the meter into the terminals of the connector module. Since the inlet and outlet holes and terminals are one-to-one matched, and the inner walls of the inlet and outlet holes are fitted with conductive sleeves, there is no need to worry about incorrect meter installation. Then, pushing the cover plate up causes the inner rod to rise, opening the elastic metal sheets and pressing them tightly against the inner walls of the inlet and outlet holes, achieving a tight connection between the terminals and the electricity meter, forming a unified whole and ensuring good conductivity. The above design greatly improves the efficiency of meter replacement while sealing the inlet and outlet holes.
[0011] A further feature of the present invention is that it also includes a safety base, and the number of the energy meters and the number of the connector modules are multiple and correspond one-to-one, with the connector modules installed and fixed on the safety base.
[0012] By adopting the above technical solution, when multiple electricity meters need to be installed on the wall, in order to reduce damage to the wall, a safety base is designed. The safety base is fixed to the wall, and then multiple connector modules are fixed to the safety base. The electricity meters are installed on the connector modules, avoiding multiple damages to the wall caused by directly installing multiple connector modules on the wall.
[0013] A further feature of the present invention is that the back of the safety base is provided with ceramic fiber paper.
[0014] By adopting the above technical solutions, flame-retardant materials must be selected during the installation of electricity meter boxes to prevent scorching of the walls and ensure safety. In the construction and industrial sectors, selecting suitable flame-retardant materials is crucial, especially to prevent wall scorching and thus ensure the safety of the overall structure. Flame-retardant ceramic fiber paper is used; this material is renowned for its excellent high-temperature resistance, with a thickness of only 3mm, yet it can withstand temperatures up to 1260°C. The use of this material effectively blocks prolonged exposure to high temperatures on the walls, thereby avoiding wall damage and potential safety risks caused by high temperatures.
[0015] A further configuration of the present invention is as follows: the cover plate is provided with a connecting plate, the connecting plate is formed with a hook, the energy meter is provided with a plurality of stops, the plurality of stops correspond one-to-one with the plurality of connecting plates, the hook hooks the stops, the energy meter is provided with an adjustment component for adjusting the movement of the stops to move closer to or further away from the hook, and the base is fixed with a stop block, the stop block is used to block the cover plate.
[0016] By adopting the above technical solution, to prevent unauthorized personnel from disassembling the electricity meter for electricity theft or theft, it is necessary to effectively lock the electricity meter and connector module. This invention designs a connecting plate on the cover plate. The hook of the connecting plate engages with the stop seat. After the operator adjusts the stop seat away from the hook using the adjusting component, the cover plate can be pulled down. The stop block assists in positioning; the operator pushes the cover plate upwards until it rests against the stop block, and then uses the adjusting component to move the stop seat so that the hook engages with it.
[0017] A further configuration of the present invention is as follows: the energy meter is provided with a plurality of sliding grooves, one end of the sliding groove is provided with a receiving cavity, the other end of the sliding groove is fixed with a spring, the plurality of sliding grooves correspond to a plurality of stop seats, the stop seat includes a first seat body and a second seat body, the first seat body is located in the sliding groove, the spring is fixed to the first seat body, the outer wall of the energy meter is formed with a receiving groove, the receiving groove is used to accommodate the hook and the connecting plate, the two ends of the receiving cavity are respectively connected to the sliding groove and the receiving groove, one end of the second seat body passes through the receiving cavity and is located in the receiving groove, and the hook hooks the end of the second seat body.
[0018] By adopting the above technical solution, the first seat slides in the groove, allowing the second seat to move closer to or further away from the hook. The spring force drives the end of the first seat that is closer to the second seat to press against the inner wall of the groove.
[0019] A further feature of the present invention is that the cross-section of the seat and the cross-section of the slide are both rectangular.
[0020] By adopting the above technical solution, both the cross-section of the slide and the cross-section of the seat are rectangular, thus preventing the seat from rotating relative to the slide.
[0021] A further configuration of the present invention is as follows: the energy meter is formed with an adjustment hole and a plurality of connecting grooves, the plurality of connecting grooves corresponding one-to-one with a plurality of sliding grooves; the side wall of the adjustment hole is formed with a receiving slot; the connecting grooves connect the sliding grooves with the receiving slots; the cross-section of the adjustment hole is circular; the adjustment assembly includes an adjustment rod and a plurality of levers fixed to the side wall of the adjustment rod; the cross-section of the adjustment rod is circular; the receiving slots and the connecting grooves are used for the levers to enter; the base is formed with a lever groove for the levers to be embedded; the levers are used to move the base away from the hook.
[0022] By adopting the above technical solution, this invention innovatively designs an adjusting rod and levers as special tools to unlock the electricity meter and connector module. The adjusting rod is inserted through the adjusting hole, and the levers of the adjusting rod enter the receiving slots. After one end of the adjusting rod abuts against the inner wall of the adjusting hole, several levers are respectively located at the connection points between several connecting slots and the receiving slots. At this time, rotating the adjusting rod causes the levers to enter the connecting slots and contact the groove of the seat body one, moving the seat body one towards the spring and causing the seat body two away from the hook, thereby unlocking the cover plate. The outer wall of the electricity meter is formed with a receiving groove, the connecting plate is embedded in the receiving groove, and the seat body two is also located inside the receiving groove.
[0023] In addition, since non-staff members cannot determine the internal structure of the electricity meter from its appearance alone, it is difficult to unlock the cover without special tools consisting of adjustment rods and levers, thus making it impossible to disassemble the electricity meter and connector module.
[0024] A further configuration of the present invention is as follows: the upper end of the inlet / outlet hole is connected to the receiving cavity; a central hole is formed in the middle of the inner rod; an insulating elastic rubber sleeve is fixed to the inner wall of the central hole; an insulating rod is inserted into the insulating elastic rubber sleeve; the upper end of the insulating rod passes through the central hole and is located outside the central hole; a connecting post is fixed on the insulating rod; the connecting post is made of conductor material; a ball head is fixed to the upper end of the insulating rod; the upper end of the insulating rod, the ball head, and the upper end of the elastic metal sheet are all located within the receiving cavity; a guide surface is formed on the lower end face of the seat body; a guide groove is formed on the guide surface; and the guide groove has two... Each end is provided with a notch, which allows the ball head to enter the guide groove. The guide surface includes a first plane, an inclined plane, and a second plane. The guide groove includes a first groove body, an inclined groove, and a second groove body. The guide groove guides the insulating rod to descend so that the connecting post is inserted between multiple elastic metal sheets. The guide groove guides the insulating rod to rise so that the connecting post is detached from the elastic metal sheets. The connector module is provided with a short-circuit circuit. The insulating rod has a wire hole formed inside. The short-circuit circuit is connected to several wires, which correspond one-to-one with several connecting posts. The wires pass through the wire hole and connect to the connecting post.
[0025] By adopting the above technical solution, the adjusting rod in the adjusting assembly rotates. As the adjusting stop moves away from the hook, the ball head at the upper end of the insulating rod moves sequentially along the first groove, the inclined groove, and the second groove, causing the insulating rod and connecting post to descend until they reach the notch on the second groove. At this point, the adjusting rod remains in a fixed state. The descent of the insulating rod causes the connecting post to insert between the elastic metal sheets, bringing the connecting post into contact with the elastic metal sheets and connecting the terminal post to the short-circuit circuit. During the process of the operator pulling down the cover plate and the inner rod descending, the elastic metal sheets remain firmly attached to the connecting post under the action of elasticity. At the same time, stop seat two disengages from hook, connecting plate and cover plate are unlocked. After pulling down cover plate, remove old energy meter and insert new energy meter. Push up cover plate to drive inner rod to rise until ball head of upper end of insulating plug on inner rod is embedded in notch on second groove. At this time, reverse adjustment rod, seat one moves away from spring under spring force, drive seat two to hook, hook seat two, lock hook, connecting plate and cover plate in position. At the same time, ball head moves from notch of second groove to notch of first groove, drive connecting post to rise relative to elastic metal sheet and separate from elastic metal sheet, realize disconnection of terminal post and short circuit.
[0026] This invention utilizes a specialized tool consisting of an adjusting rod and a lever. When the hook is unlocked, this tool energizes the terminal block and the short-circuit circuit. After disassembling and installing the electricity meter, locking the hook disconnects the terminal block from the short-circuit circuit, ensuring uninterrupted power supply during meter removal and installation. This innovative design significantly reduces maintenance time, improves work efficiency, and provides strong support for the stable operation of the power system. More importantly, the switching between opening and closing the short-circuit circuit is performed using this specialized tool, further preventing unauthorized short-circuit operations by non-staff members.
[0027] In addition, the short circuit is linked to the unlocking action of the hook position, which simplifies the steps for industrial personnel to replace electricity meters and reduces the probability of errors during operation.
[0028] A further configuration of the present invention is as follows: the first plane is located on the side of the inclined surface near the second seat, the second plane is located on the side of the inclined surface near the hook, the first groove is located on the side of the inclined groove near the second seat, the second groove is located on the side of the inclined groove near the hook, the first plane is higher than the second plane, and the first groove is higher than the second groove.
[0029] A further feature of the present invention is that it also includes a plug, wherein after the adjusting rod leaves the adjusting hole, the plug is used to be inserted into the adjusting hole, a handle is fixed at one end of the adjusting rod outside the adjusting hole, the handle has a through hole, a concave hole is formed on the outer wall of the energy meter, and a positioning rod is provided at the through hole and inserted into the concave hole.
[0030] The beneficial effects of this invention are:
[0031] 1. The connector module connects to the inlet and outlet holes of the energy meter through the terminal blocks, ensuring a stable and reliable connection. It can reliably short-circuit the inlet and outlet current of the energy meter, enabling the replacement of the energy meter without power interruption. Furthermore, the disassembly and assembly of the energy meter involves fewer steps, making the operation simple and convenient. During the replacement of the energy meter, the safety of personnel and equipment is fully protected, greatly improving work efficiency and safety.
[0032] 2. With the widespread installation of plastic meter boxes, electricity users enjoy a cleaner and more efficient energy supply. However, in recent years, incidents of plastic meter boxes burning have occurred frequently. This not only puts pressure on power supply personnel for emergency repairs and power restoration, but also triggers user complaints, opinions, and claims disputes. To address these problems, we conducted a cause analysis and damage assessment. To improve the installation environment, this invention developed a safety base for the meter box, incorporating flame-retardant ceramic fiber paper to reduce damage and losses caused by meter box combustion.
[0033] 3. The quick-installation electricity meter box developed in this invention enables rapid replacement of electricity meters without power outages, representing a significant technological breakthrough. Furthermore, it demonstrates immense potential in terms of social, economic, and safety benefits. By reducing power outage time, improving power supply reliability, saving costs, and enhancing equipment safety, these innovative achievements provide strong guarantees for the stable operation of the power system and the safety of users' electricity consumption.
