Each replacement requires coordination and communication with customers regarding power outages, which is both time-consuming and labor-intensive. Furthermore, improper installation can easily cause the meter to burn out, leading to service and financial losses. Replacing a three-phase, direct-flow meter can also cause power outages for nearby customers, severely impacting their electricity needs. Summary of the Invention
[0012] The purpose of the present invention is to provide a quick-install electric energy meter box, which has the effect of quickly disassembling and assembling the electric energy meter.
[0013] The above technical objectives of the present invention are achieved through the following technical solutions: a quick-install electric energy meter box, including an electric energy meter and a connector module, the connector module including a base, a plurality of terminals installed on the base, and a plurality of cover plates corresponding to the plurality of terminals, the terminals including a conductor cylinder fixed to the base, a plurality of elastic metal sheets fixed to the end of the conductor cylinder, and an inner rod passing through the conductor cylinder, the surface of the inner rod being provided with an adjustment surface for adjusting the opening or closing of the plurality of elastic metal sheets, the cover plate being fixed to the inner rod, and the electric energy meter being provided with an inlet and outlet wire hole for plugging in the terminals.
[0014] By adopting the above technical solution, the present invention designs a connector module, in which the terminal posts in the connector module replace the input and output wires of the electric energy meter, which can not only stabilize the electric energy meter, but also clearly calibrate the position of the input and output wires, ensuring the accuracy of the electric energy meter installation. When removing the electric energy meter, the cover plate is pulled downward, and the cover plate drives the inner rod to descend, and the elastic metal sheets are moved closer together, reducing the force between the terminal posts and the electric energy meter input and output holes, making it easier to directly unplug the electric energy meter. When installing the electric energy meter, the input and output holes of the new electric energy meter can be aligned with the terminal posts, and the electric energy meter can be plugged into the terminal posts of the connector module. Since the input and output holes and the terminal posts are one-to-one corresponding and matched, and the inner wall of the input and output holes is installed with a conductive sleeve, there is no need to worry about the electric energy meter being installed incorrectly. Then, the cover plate is pushed up, and the cover plate drives the inner rod to rise and then spreads the elastic metal sheet and opens it. The elastic metal sheet is pressed tightly against the inner wall of the input and output holes, realizing a tight combination of the terminal posts and the electric energy meter, forming a whole, ensuring good conductive performance. The above design greatly improves the efficiency of meter replacement and at the same time closes the inlet and outlet holes.
[0015] The present invention is further configured to include a safety base, the number of the electric energy meters and the number of the connector modules are multiple and correspond one to one, and the connector modules are mounted and fixed on the safety base.
[0016] By adopting the above technical solution, when multiple electricity meters need to be installed on a wall, in order to reduce damage to the wall, a safety base is designed. The safety base is fixed on the wall, and then multiple connector modules are fixed on the safety base. The electricity meter is installed on the connector module, avoiding multiple damages to the wall caused by directly installing multiple connector modules on the wall.
[0017] The present invention is further configured as follows: ceramic fiber paper is provided on the back of the safety base.
[0018] By adopting the above technical solution, flame-retardant materials are required during installation of the electricity meter box to prevent wall burns and ensure safety. Choosing the right flame-retardant material is crucial in the construction and industrial sectors, especially to prevent wall burns and ensure the safety of the overall structure. Ceramic fiber paper, a flame-retardant material renowned for its exceptional high-temperature resistance, is used. At a thickness of only 3mm, it can withstand temperatures up to 1260°C. This material effectively blocks prolonged high temperatures from scorching the wall, thereby avoiding damage and potential safety risks.
[0019] The present invention is further configured as follows: the cover plate is provided with a connecting plate, the connecting plate is formed with a hook, the electric energy meter is provided with a plurality of blocks, the plurality of blocks correspond one-to-one to the plurality of connecting plates, the hook hooks the blocks, the electric energy meter is provided with an adjustment component for adjusting the movement of the blocks to move closer to or away from the hook, the base is fixed with a block, and the block is used to block the cover plate.
[0020] By adopting the above technical solution, in order to prevent unauthorized disassembly of the energy meter by non-staff members to steal electricity or the energy meter, it is necessary to effectively lock the energy meter and the connector module. The present invention designs a connecting plate on the cover plate, and the hook portion of the connecting plate hooks the stopper. The staff can only pull the cover plate downward after adjusting the stopper away from the hook portion using the adjustment assembly. The stopper functions as an auxiliary positioning block. The staff pushes the cover plate upward until it contacts the blocker, and then uses the adjustment assembly to adjust the stopper so that the hook portion hooks the blocker.
[0021] The present invention is further configured as follows: the electric energy meter is provided with a plurality of slide grooves, one end of the slide groove is provided with an accommodating cavity, the other end of the slide groove is fixed with a spring, the plurality of slide grooves respectively correspond to a plurality of block seats, the block seat includes a seat body one and a seat body two, the seat body one is located in the slide groove, the spring is fixed to the seat body one, the outer wall of the electric energy meter is formed with an accommodating groove, the accommodating groove is used to accommodate the hook and the connecting plate, the two ends of the accommodating cavity are respectively connected with the slide groove and the accommodating groove, one end of the seat body two passes through the accommodating cavity and is located in the accommodating groove, and the hook hooks the two end portions of the seat body.
[0022] By adopting the above technical solution, the seat body 1 slides in the slide groove, so that the seat body 2 is close to or away from the hook portion, and the spring force drives the end of the seat body 1 close to the seat body 2 to rest on the inner wall of the slide groove.
[0023] The present invention is further configured such that a cross section of the seat body and a cross section of the slide groove are both rectangular.
[0024] By adopting the above technical solution, the cross-sections of the slide groove and the seat body 1 are both rectangular, which prevents the seat body 1 from rotating relative to the slide groove.
[0025] The present invention is further configured as follows: the electric energy meter is formed with an adjustment hole and a plurality of connecting grooves, the plurality of connecting grooves correspond one to one with the plurality of slide grooves, the side wall of the adjustment hole is formed with an accommodating notch, the connecting groove connects the slide groove with the accommodating notch, the cross-section of the adjustment hole is circular, the adjustment assembly includes an adjustment rod and a plurality of shift blocks fixed on the side wall of the adjustment rod, the cross-section of the adjustment rod is circular, the accommodating notch and the connecting groove are used for the shift blocks to enter, the seat body is formed with a shift groove for the shift block to be embedded, and the shift block is used to shift the seat body away from the hook.
[0026] By adopting the above-mentioned technical solution, the present invention uniquely designs an adjustment rod and a shift block as a dedicated tool for unlocking the electric energy meter and the connector module. The adjustment rod is inserted into the adjustment hole, and the shift block of the adjustment rod enters the receiving slot. After one end of the adjustment rod abuts the inner wall of the adjustment hole, the shift blocks are located at the connection points between the connecting grooves and the receiving slots. At this time, the adjustment rod is rotated, and the shift blocks enter the connecting grooves and contact the embedded groove of the first seat body. This moves the first seat body toward the spring, driving the second seat body away from the hook, thereby unlocking the cover plate. The outer wall of the electric energy meter is formed with a receiving groove, and the connecting plate is embedded in the receiving groove. The second seat body is also located within the receiving groove.
[0027] In addition, since non-staff cannot determine the internal structure of the electricity meter from the appearance alone, it is difficult to unlock the cover without special tools consisting of an adjustment rod and a dial block, and thus it is impossible to disassemble the electricity meter and the connector module.
[0028] The present invention is further configured as follows: the upper end of the inlet and outlet holes is communicated with the accommodating cavity, a middle hole is formed in the middle of the inner rod, an insulating elastic rubber sleeve is fixed to the inner wall of the middle hole, an insulating plug rod is inserted into the insulating elastic rubber sleeve, the upper end of the insulating plug rod is located outside the middle hole after passing through the middle hole, a connecting column is fixed on the insulating plug rod, the connecting column is made of a conductor, a ball head is fixed on the upper end of the insulating plug rod, a ball head is formed on the upper end of the insulating plug rod, the upper end of the insulating plug rod, the ball head and the upper end of the elastic metal sheet are all located in the accommodating cavity, the two lower end faces of the seat body are formed with guide surfaces, the guide surfaces are formed with guide grooves, and the two ends of the guide grooves are formed with guide grooves. The ends are each provided with a notch, the notch is for the ball head to enter the guide groove, the guide surface includes a first plane, an inclined surface, 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 column is plugged between the multiple elastic metal sheets, and the guide groove guides the insulating rod to rise so that the connecting column is separated from the elastic metal sheet, a short-circuit circuit is provided in the connector module, and a wire hole is formed in the insulating rod. The short-circuit circuit is connected to a number of wires, and the several wires correspond one-to-one to the several connecting columns. The wires are connected to the connecting columns after passing through the wire holes.
[0029] By adopting the above technical solution, the adjustment rod in the adjustment assembly rotates. As the entire adjustment block moves away from the hook, the ball head at the upper end of the insulating rod moves sequentially along the first slot, the inclined slot, and the second slot, driving the insulating rod and the connecting post downward until they reach the notch in the second slot. At this point, the adjustment rod remains in place. The insulating rod descends, driving the connecting post to insert between the elastic metal sheets, contacting the connecting post with the elastic metal sheets and connecting the terminal to the short-circuit circuit. As the operator pulls down the cover and the inner rod descends, the elastic metal sheet remains in contact with the connecting post due to the elastic force. At the same time, the second block seat is disengaged from the hook, and the connecting plate and the cover plate are in an unlocked state. After pulling down the cover plate, the old electricity meter is removed, and then the new electricity meter is plugged in. The cover plate is pushed up to drive the inner rod to rise until the ball head at the upper end of the insulating plug rod on the inner rod is embedded in the notch on the second slot body. At this time, the adjusting rod is reversed, and the seat body one moves away from the spring under the action of the spring force, driving the seat body two to approach the hook, so that the hook hooks the seat body two, locking the position of the hook, connecting plate and cover plate. At the same time, the ball head moves from the notch of the second slot body along the second slot body, the inclined slot, and the first slot body to the notch of the first slot body, driving the connecting column to rise relative to the elastic metal sheet and then separate from the elastic metal sheet, thereby disconnecting the terminal from the short-circuit circuit.
[0030] The present invention utilizes a dedicated tool consisting of an adjustment rod and a shift block. When the dedicated tool is used to unlock the hook position, the terminal is energized to the shorting circuit. After removing or installing the meter, the dedicated tool is used to lock the hook position, disconnecting the terminal from the shorting circuit, ensuring that the meter remains powered during removal and installation. This innovative design significantly reduces maintenance time, improves work efficiency, and provides a strong guarantee for the stable operation of the power system. More importantly, the switching between disconnecting and closing the shorting circuit is performed using a dedicated tool, further preventing unauthorized shorting operations by non-staff members.
[0031] In addition, the on-off of the short circuit is linked to the unlocking action of the hook position, which simplifies the steps for industrial personnel to replace the electricity meter and reduces the probability of errors during the operation.
[0032] The present invention is further configured as follows: the first plane is located on the side of the inclined surface close to the seat body 2, the second plane is located on the side of the inclined surface close to the hook portion, the first groove body is located on the side of the inclined slot close to the seat body 2, the second groove body is located on the side of the inclined slot close to the hook portion, the first plane is higher than the second plane, and the first groove body is higher than the second groove body.

[0034] The beneficial effects of the present invention are:
[0035] 1. The connector module is plugged into the inlet and outlet holes of the energy meter through the terminal posts, making the connection of the inlet and outlet holes of the energy meter stable and reliable. It can reliably short-circuit the inlet and outlet currents of the energy meter, and realize the function of replacing the energy meter without powering off. In addition, the disassembly and assembly of the energy meter requires fewer steps, and the operation is simple and convenient. The safety of workers and equipment is fully protected during the replacement of the energy meter, which greatly improves work efficiency and safety.
[0036] 2. With the widespread installation of plastic meter boxes, electricity users have enjoyed a cleaner and more efficient energy supply. However, in recent years, incidents of plastic meter box burns have become frequent. This not only places pressure on power supply personnel to urgently repair and restore power, but also triggers user complaints, complaints, and claims disputes. To address these issues, we conducted a cause analysis and damage assessment. To improve the installation environment, we developed a safety base for the meter box, equipped with a flame-retardant ceramic fiber paper material, to reduce damage and losses caused by meter box burns.
[0037] 3. The quick-install energy meter box developed by this invention enables rapid replacement of energy meters without power outages. This represents not only a significant technical breakthrough but also demonstrates enormous potential for social, economic, and safety benefits.
