[0016] The working principle and beneficial effects of the present invention are: In the present invention, the box body is the outer shell of the entire electric energy metering box. It is a structure with certain strength and sealing performance, which is used to protect the internal electrical components. A through hole is opened on the side of the box body, and the through hole is used for external cables to enter the box body and connect with the equipment related to electric energy metering. The first clamp is installed at the through hole position of the box body. The first clamp is designed with a plurality of first threading holes arranged in an arranged manner. The main function of the first threading hole is to allow different cables such as power cables, signal cables, etc. to pass through in an orderly manner and enter the box body. The second clamp is rotatably arranged on the first clamp by a rotating shaft. When it is necessary to protect the cable, the second clamp can be rotated to a specific position, thereby blocking part of the first threading hole. When it is necessary to add cables or perform maintenance operations, the second clamp can be rotated in the opposite direction to cancel the blocking of the threading hole, so as to operate the cable. The locking member is slidably and rotatably arranged on the first clamp. When it is necessary to fix the position of the second clamp, the locking member can be slidably and rotated. For example, the locking member can slide along the slideway on the first clamping member to the top of the second clamping member, and then rotate so that the pressing part of the locking member is tightly pressed on the second clamping member, thereby ensuring that the second clamping member will not rotate at will, thus playing a locking role. When the position of the second clamping member needs to be adjusted, the locking member is operated in the reverse direction, that is, first rotated so that it no longer presses the second clamping member, and then slid away from the top of the second clamping member to cancel the pressing state.

[0017] During the initial installation of the electric energy meter box, first install the first clamp at the through hole of the box body. Then, according to actual needs, the corresponding number of cables are inserted into the box body through the first threading hole. After all the required cables have been inserted, rotate the second clamp to block the unused first threading hole. Then, slide the locking member to a suitable position above the second clamp, and rotate the locking member to press the second clamp. In this way, the setting of the protection state is completed, and unauthorized cables can no longer be inserted into the blocked first threading hole, thereby improving the safety of the electric energy meter box. In subsequent maintenance or when new cables need to be added, first operate the locking member to cancel the pressing of the second clamp. First rotate the locking member in the opposite direction, and then slide the locking member away from the top of the second clamp. Then, rotate the second clamp to cancel the blocking of the corresponding first threading hole, and pass the new control line through the threading hole. After completing the cable operation, rotate the second clamp and operate the locking member again to restore the protection state.

[0018] From a security perspective, unauthorized lines may often have uneven quality, and they are like time bombs hidden in the dark. Once these lines are mixed into the meter box, they may cause sparks or even fires due to line aging, short circuits and other problems. By strictly prohibiting their entry, it is like building an indestructible firewall between danger and safety, keeping these potential safety hazards out, effectively protecting the safety of the surrounding environment and people's lives and property, and strangling fire hazards in the cradle, so that the area where the meter box is located is always in a safe state. The electric energy meter box plays an important role in accurately counting electric energy consumption. Every kilowatt-hour record is related to the interests of users and power suppliers. If unauthorized lines enter quietly, they may interfere with the normal metering process and cause confusion and inaccuracy in the data. Whether it is malicious theft of electricity or unintentional line interference, it will break the balance of fair measurement. Through the role of the first card and the second card, it is ensured that only legal and compliant lines participate in the process of electric energy metering, so that every data is true and reliable, ensuring the accuracy and fairness of electric energy metering, and maintaining the normal order of the power market. The power system is a complex and sophisticated network. Any abnormal line access may trigger a chain reaction and affect the stability of the entire power grid. Just like throwing a stone into a calm lake will cause ripples, unauthorized lines entering the meter box may cause voltage fluctuations, abnormal current and other problems, which in turn have an impact on the entire power system. By preventing these lines from entering, it is like adding a guarantee for the stable operation of the power system, allowing electricity to be transmitted and distributed on a safe and stable track, ensuring that electrical equipment can operate normally, and avoiding major power system failures caused by small line violations.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0024] Reference Figure 1 to Figure 8 , which is the eighth embodiment of the present invention, proposes an electric energy meter box with a security structure, including: a box body 1, the box body 1 has a through hole 101, a first clamp 2 is arranged on the through hole 101, the first clamp 2 has a first threading hole 201, the first threading hole 201 is arranged in a plurality of rows, and the first threading hole 201 is used for passing cables, a second clamp 3 is rotatably arranged on the first clamp 2, and the second clamp 3 blocks or cancels blocking of part of the threading hole after rotation, and a locking member 4 is slidably and rotatably arranged on the first clamp 2, and the locking member 4 presses or cancels pressing of the second clamp 3 after sliding and rotating.

[0025] In this embodiment, the box body 1 is used as the outer shell of the entire electric energy metering box. It is a structure with certain strength and sealing performance, which is used to protect the internal electrical components. A through hole 101 is opened on the side of the box body 1. This through hole 101 is used for external cables to enter the box body 1 and connect with the equipment related to electric energy metering. The first clamp 2 is installed at the position of the through hole 101 of the box body 1. The first clamp 2 is designed with a plurality of first threading holes 201 arranged in an arranged manner. The main function of the first threading hole 201 is to allow different cables such as power cables, signal cables, etc. to pass through in an orderly manner and enter the box body 1. The second clamp 3 is rotatably arranged on the first clamp 2 through a rotating shaft. When it is necessary to protect the cable, the second clamp 3 can be rotated to a specific position to block part of the first threading hole 201. When it is necessary to add cables or perform maintenance operations, the second clamp 3 can be rotated in the opposite direction to cancel the blocking of the threading hole so as to operate the cable. The locking member 4 is slidably and rotatably arranged on the first clamp 2. When the position of the second clamping member 3 needs to be fixed, the locking member 4 can slide and rotate. For example, the locking member 4 can slide along the slideway on the first clamping member 2 to the top of the second clamping member 3, and then rotate so that the pressing part of the locking member 4 is tightly pressed on the second clamping member 3, thereby ensuring that the second clamping member 3 will not rotate at will, playing a locking role. When the position of the second clamping member 3 needs to be adjusted, the locking member 4 is operated in the reverse direction, that is, first rotated so that it no longer presses the second clamping member 3, and then slid away from the top of the second clamping member 3 to cancel the pressing state.

[0026] During the initial installation of the electric energy meter box, the first clamp 2 is first installed at the through hole 101 of the box body 1. Then, according to actual needs, the corresponding number of cables are inserted into the box body 1 through the first threading hole 201. After all the required cables have been inserted, the second clamp 3 is rotated to block the unused first threading hole 201. Then, the locking member 4 is slid to a suitable position above the second clamp 3, and the locking member 4 is rotated to press the second clamp 3. In this way, the setting of the protection state is completed, and unauthorized cables can no longer be inserted into the blocked first threading hole 201, thereby improving the safety of the electric energy meter box. In subsequent maintenance or when new cables need to be added, the locking member 4 is first operated to cancel the pressing of the second clamp 3. First, the locking member 4 is rotated in the opposite direction, and then the sliding locking member 4 is moved away from the second clamp 3. Then, the second clamp 3 is rotated to cancel the blocking of the corresponding first threading hole 201, and the new control line is passed through the threading hole. After the cable operation is completed, the second clamping member 3 and the operation locking member 4 are rotated again to restore the protection state.

[0027] From a security perspective, unauthorized lines may often have uneven quality, and they are like time bombs hidden in the dark. Once these lines are mixed into the meter box, they may cause sparks or even fires due to line aging, short circuits and other problems. By strictly prohibiting their entry, it is like building an indestructible firewall between danger and safety, keeping these potential safety hazards out, effectively protecting the safety of the surrounding environment and people's lives and property, and strangling fire hazards in the cradle, so that the area where the meter box is located is always in a safe state. The electric energy meter box plays an important role in accurately counting electric energy consumption. Every record of electricity is related to the interests of users and power suppliers. If unauthorized lines enter quietly, they may interfere with the normal metering procedure and cause confusion and inaccuracy in data. Whether it is malicious theft of electricity or unintentional line interference, it will break the balance of fair measurement. Through the role of the first card 2 and the second card 3, it is ensured that only legal and compliant lines participate in the process of electric energy metering, so that each data is true and reliable, ensuring the accuracy and fairness of electric energy metering, and maintaining the normal order of the power market. The power system is a complex and sophisticated network. Any abnormal line access may trigger a chain reaction and affect the stability of the entire power grid. Just like throwing a stone into a calm lake will cause ripples, unauthorized lines entering the meter box may cause voltage fluctuations, abnormal current and other problems, which in turn have an impact on the entire power system. By preventing these lines from entering, it is like adding a guarantee for the stable operation of the power system, allowing electricity to be transmitted and distributed on a safe and stable track, ensuring that electrical equipment can operate normally, and avoiding major power system failures caused by small line violations.

[0028] Further, the second clamping member 3 includes: a rotating member 301, which is rotatably set on the first clamping member 2, and the upper end of the rotating member 301 has an arc groove 302, which is connected to the first threading hole 201, and the rotating member 301 passes through the bottom of the first clamping member 2, and the stopper 303 is raised and lowered and slidably set on the rotating member 301. After the stopper 303 is raised and lowered, it is inserted into or canceled from the first threading hole 201, and after the stopper 303 slides, it abuts or cancels the abutment with the cable.

[0029] In this embodiment, the rotating member 301 is rotatably disposed on the first clamping member 2 via a rotating shaft. An arc groove 302 is designed at the upper end of the rotating member 301, and the arc groove 302 is connected to the first threading hole 201, so that the cable can pass smoothly under certain circumstances. The rotating member 301 passes through the bottom of the first clamping member 2, and it also has a clamping portion and a mounting groove. The clamping portion can be a protruding structure with a certain elasticity, which is convenient for clamping operation with other components.

[0030] The stopper 303 can be lifted and slid on the rotating member 301. When the first threading hole 201 needs to be blocked, the stopper 303 can be raised and then inserted into the first threading hole 201. The size of the stopper 303 matches the first threading hole 201, and when it is inserted, it can tightly block the threading hole. When it is necessary to adjust the cable or perform other operations, the stopper 303 can cancel the insertion state. In addition, the stopper 303 can also slide in the horizontal direction, and when it slides, it can abut or cancel the abutment with the cable, which is very useful when arranging the cables or fixing the cable positions. In the initial state of the electric energy meter box, the stopper 303 is in a descending state, and the insertion into the first threading hole 201 is canceled. When the cables need to be arranged, the cables are introduced through the first threading hole 201 and the arc groove 302 on the rotating member 301. At this time, the stopper 303 can be slid to abut the cables, and the cables are arranged in a suitable position to ensure that the cables are arranged neatly and avoid entanglement and confusion between the cables. When the cables are arranged or it is necessary to prevent unauthorized cables from entering, operate the stopper 303 to make it snap into the first threading hole 201. When there are already cables connected to the meter box, it is necessary to prevent other cables from mixing in, and the stopper 303 is inserted into the unused first threading hole 201. In subsequent maintenance or when new cables need to be added, the second clamp 3 needs to be adjusted. The stopper 303 is removed from the state of being inserted into the first threading hole 201, and the cable can be adjusted or a new cable can be inserted. When the new cable is connected, operate the stopper 303 again to insert it into the first threading hole 201, and fix it with the connector to restore the protection state. The operation is simple, which is convenient for the operator to maintain, and solves the safety problems that may arise from the theft of electricity and the theft of electricity.

[0031] Furthermore, the rotating member 301 has a mounting portion 304, and the blocking member 303 is slidable and raised and lowered relative to the mounting portion 304. The mounting portion 304 is L-shaped, and has a transverse fixing portion 305 and a vertical fixing portion 306. It also includes a first elastic member 307. One end of the first elastic member 307 acts on the transverse fixing portion 305, and the other end acts on the blocking member 303 to provide a force for the blocking member 303 to be inserted into the first threading hole 201. One end of the second elastic member 308 acts on the vertical fixing portion 306, and the other end acts on the blocking member 303 to provide a force for the blocking member 303 to abut against the cable.

[0032] In this embodiment, in the electric energy meter box with a security structure, the mounting portion 304 of the rotating member 301 is L-shaped. Among them, the horizontal fixing portion 305 is placed horizontally, and the vertical fixing portion 306 is perpendicular to the horizontal fixing portion 305. One end of the first elastic member 307 is connected to the horizontal fixing portion 305, and the other end is connected to the stopper 303. When it is in a natural state, it will apply a force to the stopper 303, and the direction of this force is to cause the stopper 303 to be inserted into the first threading hole 201. In the initial state, the first elastic member 307 is in a stretched state, storing a certain amount of elastic potential energy, and is always ready to push the stopper 303 to the first threading hole 201. One end of the second elastic member 308 acts on the vertical fixing portion 306, and the other end acts on the stopper 303. When the second elastic member 308 abuts against the cable, it will generate a force on the stopper 303, so that the stopper 303 has a force to press against the cable.

[0033] When the cable is installed or the unused first threading hole 201 needs to be blocked, the first elastic member 307 comes into play. Due to the elastic potential energy stored in the first elastic member 307, it will make the stopper 303 inserted into the first threading hole 201, automatically push the stopper 303 into the unused threading hole to achieve blocking. In subsequent maintenance or when a new cable needs to be added, when the stopper 303 needs to be withdrawn from the first threading hole 201, the staff needs to overcome the pulling force of the first elastic member 307. When the stopper 303 drops, the second elastic member 308 will make the stopper 303 abut against the newly introduced cable, which is convenient for cable arrangement and positioning.

[0034] Furthermore, the blocking member 303 has an arc-shaped abutting portion 309 and a cylindrical inserting portion 310 , and the cylindrical inserting portion 310 is located at the lower end of the arc-shaped abutting portion 309 .

[0035] In this embodiment, the arcuate abutment portion 309 of the stopper 303 presents a smooth arcuate profile. The arcuate design enables the stopper 303 to better fit the outer surface of the cable when in contact with the cable. After the cable passes through the first threading hole 201, the arcuate abutment portion 309 can abut along the arcuate surface of the cable, increasing the contact area, thereby improving the stability of the cable position fixation. The cylindrical insertion portion 310 is located at the lower end of the arcuate abutment portion 309. The main function is to insert into the first threading hole 201 to achieve blocking of the threading hole. During the cable arrangement process of the electric energy meter box, after the cable passes through the first threading hole 201, the arcuate abutment portion 309 of the stopper 303 begins to play a role. When the unused first threading hole 201 needs to be blocked, the cylindrical insertion portion 310 of the blocking member 303 starts to work, and when all cables to be connected have been installed, the blocking member 303 is driven by the relevant mechanism, and the cylindrical insertion portion 310 is accurately inserted into the corresponding first threading hole 201. Since the cylindrical insertion portion 310 matches the shape of the first threading hole 201, it can effectively prevent unauthorized cables from entering the meter box.

[0036] Furthermore, the first clamping member 2 has an anti-slipping portion 202, and the locking member 4 includes: a first annular pressing portion 401, the first annular pressing portion 401 is used to press the second clamping member 3, a connecting column 402 is arranged on the first annular pressing portion 401, and the second annular pressing portion 403 is used to abut against the anti-slipping portion 202. The first annular pressing portion 401 and the second annular pressing portion 403 both have a yield groove 404. A third elastic member 405 is arranged in the connecting column 402, one end of which acts on the first annular pressing portion 401, and the other end acts on the second annular pressing portion 403, providing a force for the first annular pressing portion 401 to clamp with the second clamping member 3, and at the same time providing a force for the first annular pressing portion 401 to abut against the anti-slipping portion 202.

[0037] In the present embodiment, the anti-slip portion 202 on the first card 2 is a special structural design, for example, it can be an annular edge protruding outward or a convex block with a specific angle, and its main function is to cooperate with the relevant part of the locking member 4 to prevent the locking member 4 from accidentally disengaging. The shape of the first annular pressing portion 401 matches the partial structure of the second card 3, and it can be an annular metal sheet with a certain width and thickness. When the second card 3 needs to be locked, the first annular pressing portion 401 can be tightly pressed on the second card 3, thereby limiting the rotation of the second card 3. The connecting column 402 is a key component connecting the first annular pressing portion 401 and the second annular pressing portion 403. It is a cylindrical shape, and there is a certain space inside for placing the third elastic member 405. The second annular pressing portion 403 is used to abut against the anti-slip portion 202, and it is similar to the first annular pressing portion 401 and is also an annular structure. And the first annular pressing portion 401 and the second annular pressing portion 403 both have a clearance groove 404, which can provide space for the movement of other components during installation and operation to avoid interference. The third elastic member 405 is arranged in the connecting column 402 and is a compression spring. One end of it acts on the first annular pressing portion 401, and the other end acts on the second annular pressing portion 403. In the initial state, the third elastic member 405 is in a compressed state, and it applies a force to the first annular pressing portion 401, so that the first annular pressing portion 401 is in close contact with the second clamping member 3, and also applies a force to the second annular pressing portion 403, so that the second annular pressing portion 403 is in contact with the anti-slip portion 202. When the electric energy meter box needs to be maintained or the second clamping member 3 needs to be adjusted, the elastic force of the third elastic member 405 needs to be overcome. The operator applies an external force to the locking member 4, which causes the first annular pressing portion 401 to move away from the second clamping member 3, and the second annular pressing portion 403 also disengages from the anti-slip portion 202. When the maintenance or adjustment operation is completed, the external force applied to the locking member 4 is released. Due to the elastic restoring force of the third elastic member 405, the first annular pressing portion 401 will re-press the second clamping member 3, and the second annular pressing portion 403 will again abut against the anti-slip portion 202.

[0038] Furthermore, the anti-slip portion 202 has a positioning hole 203, which is arranged in a circle and also includes: a positioning bead 5, which is arranged on the second annular pressure portion 403, and there are several positioning beads 5, which correspond one to one with the positioning holes 203. The unlocking member 6 is used to unlock the locking member 4. The unlocking member 6 has an unlocking portion 601 and an abutting portion 602. The unlocking portion 601 is used to abut against the positioning bead 5. When the unlocking portion 601 abuts against the positioning bead 5, the abutting portion 602 abuts against the wall of the give way groove 404. After the unlocking member 6 rotates, the locking member 4 is unlocked from the first clamping member 2.

[0039] In this embodiment, the positioning holes 203 on the anti-slip part 202 are arranged in a circle, and these positioning holes 203 provide matching positions for the subsequent positioning beads 5. The positioning beads 5 are arranged on the second annular pressing part 403, and the number corresponds to the positioning holes 203. The positioning beads 5 can be metal beads with a diameter slightly smaller than the positioning holes 203. Under normal conditions, they can be partially embedded in the positioning holes 203 to play a role in positioning and preventing the locking member 4 from accidentally moving. The unlocking member 6 includes an unlocking portion 601 and an abutting portion 602. The unlocking portion 601 is used to abut against the positioning beads 5. The unlocking portion 601 is a convex structure with a certain angle. When it contacts the positioning beads 5, it can push the positioning beads 5 out of the positioning holes 203. The abutting portion 602 abuts against the wall of the give way groove 404 during the unlocking operation, providing a support point for the unlocking action. When the electric energy meter box is working normally and the locking member 4 is in a locked state, the positioning beads 5 are embedded in the positioning holes 203 of the anti-slip part 202. The elastic force of the third elastic member 405 enables the second annular pressing portion 403 to tightly press the positioning bead 5 into the positioning hole 203, ensuring a stable and reliable connection between the locking member 4 and the first clamping member 2, and preventing the locking member 4 from being unlocked due to unauthorized operation.

[0040] When the locking member 4 needs to be unlocked, the operator inserts the unlocking member 6. The unlocking portion 601 of the unlocking member 6 abuts against the positioning bead 5, and the abutting portion 602 abuts against the connecting column 402. When the operator rotates the unlocking member 6, the unlocking portion 601 applies an outward thrust to the positioning bead 5, so that the positioning bead 5 withdraws from the positioning hole 203. Due to the push of the unlocking portion 601 and the support of the abutting portion 602, the elastic force of the third elastic member 405 is overcome, so that the locking between the locking member 4 and the first clamping member 2 is released.

[0041] Furthermore, it also includes: a mounting frame 7, which is arranged in the box body 1, an electric meter 8, which is arranged on the mounting frame 7, and an air switch 9 which is arranged on the mounting frame 7 and is located below the electric meter 8.

[0042] In this embodiment, the mounting frame 7 is arranged in the box body 1, which plays the role of supporting and fixing other components. The structure of the mounting frame 7 needs to have sufficient strength and stability to ensure that the electric meter 8 and the air switch 9 installed thereon can work safely and stably. The electric meter 8 is arranged on the mounting frame 7 to measure the consumption of electric energy. The installation method between the electric meter 8 and the mounting frame 7 needs to ensure the accuracy and reliability of the electric meter 8, and at the same time facilitate installation, maintenance and replacement. Usually, the electric meter 8 can be fixed on the mounting frame 7 by means of a slot, bolts, etc., to ensure that it will not shake or shift easily during operation. The air switch 9 is arranged on the mounting frame 7 and is located below the electric meter 8. The air switch 9 plays the role of overload and short circuit protection in the circuit. Placing it below the electric meter 8 is convenient for wiring connection on the one hand, and on the other hand, it also meets the conventional layout requirements of electrical equipment. The connection method between the air switch 9 and the mounting frame 7 can be screw fixing, etc., to ensure that it will not loosen during actions such as tripping.

[0043] The electric meter 8 and the air switch 9 are centrally installed in the electric energy metering box through the mounting frame 7, which effectively utilizes the internal space of the box body 1 and makes the layout of the entire electrical equipment more compact and reasonable. In some distribution rooms or distribution boxes with limited space, this centralized installation method can improve space utilization and facilitate equipment management and maintenance. The electric meter 8 and the air switch 9 are both installed on the same mounting frame 7. When operations such as meter reading, maintenance or replacement of equipment are required, operators can work in a relatively concentrated area, which improves work efficiency. The mounting frame 7 provides a stable installation foundation for the electric meter 8 and the air switch 9, reducing the risk of electrical failures that may be caused by shaking or loosening of the equipment. At the same time, a reasonable layout is also conducive to the dissipation of heat and reduces the possibility of equipment overheating.

[0044] Furthermore, the cylindrical inserting portion 310 extends into the arc-shaped groove 302 .

[0045] In this embodiment, the cylindrical insert 310 is a structural component with a cylindrical shape. Its size and shape are designed to cooperate with the arc groove 302. The diameter and length of the cylindrical insert 310 need to be matched according to the size and depth of the arc groove 302 to ensure smooth insertion and achieve specific functions. When the cylindrical insert 310 extends into the arc groove 302, accurate positioning between the two components can be achieved. This positioning method can ensure that the relevant components maintain a relatively stable positional relationship during assembly or operation. In the electric energy metering box, the cooperation between the arc groove 302 and the cylindrical insert 310 can provide a mechanical limit function. The range of motion of the stopper 303 when the second clamp 3 rotates is limited to prevent excessive movement or dislocation. Through the connection between the cylindrical insert 310 and the arc groove 302, the connection points of the structure are increased, thereby enhancing the stability of the entire structure.

[0046] Furthermore, it also includes: a telescopic column 10, which is arranged in the connecting column 402, a third elastic member 405 is arranged outside the telescopic column 10, one end of the telescopic column 10 is arranged on the first annular pressing portion 401, and the other end is arranged on the second annular pressing portion 403.

[0047] In this embodiment, the telescopic column 10 is arranged in the connecting column 402, and it can perform telescopic movement inside the connecting column 402. The structural design of the telescopic column 10 enables it to change its own length according to the action of external force or the deformation of the internal elastic member. The telescopic column 10 is composed of a plurality of nested pipes, or a rod with a special telescopic structure to achieve a flexible telescopic function. The third elastic member 405 is arranged on the outside of the telescopic column 10, and it cooperates with the telescopic column 10 to work. The third elastic member 405 is an elastic element such as a spring, and its elastic deformation can provide power or resistance for the telescopic movement of the telescopic column 10. When the telescopic column 10 is extended and retracted, the third elastic member 405 will be compressed or stretched accordingly, thereby storing or releasing elastic potential energy. One end of the telescopic column 10 is arranged on the first annular pressing portion 401, and the other end is arranged on the second annular pressing portion 403. This enables the telescopic column 10 to associate the movement of the first annular pressing portion 401 and the second annular pressing portion 403 during operation. When the first annular pressing portion 401 or the second annular pressing portion 403 is subjected to external force, the force will be transmitted and buffered through the telescopic column 10 and the third elastic member 405. When the electric energy meter box is subjected to external impact or vibration, the telescopic column 10 and the third elastic member 405 can play a role in buffering and shock absorption. Through the telescopic movement of the telescopic column 10 and the elastic deformation of the third elastic member 405, external energy can be absorbed and dissipated, reducing the impact on the internal equipment of the meter box. The combination of the telescopic column 10 and the third elastic member 405 can be used to adjust and balance the force or position relationship between the first annular pressing portion 401 and the second annular pressing portion 403. Through the mutual cooperation between the connecting column 402, the telescopic column 10 and the two annular pressing portions, a more stable mechanical structure is formed. During long-term use, even if part of the structure is slightly deformed or loose, this structure can maintain the overall stability and improve the reliability of the meter box.

[0048] Furthermore, the anti-slip portion 202 has a connecting hole 205 , which is connected to the positioning hole 203 . The diameter of the connecting hole 205 is smaller than that of the positioning hole 203 , and is used for inserting the unlocking portion 601 .

[0049] In this embodiment, the anti-slip part 202 is a specific structural component, which has a connecting hole 205. The existence of the connecting hole 205 provides a channel for the insertion of the unlocking part 601. The connecting hole 205 is connected to the positioning hole 203, and its diameter is smaller than the diameter of the positioning hole 203. This design forms a special connection area in the structure. The size design of the connecting hole 205 is specifically used for the insertion of the unlocking part 601. The unlocking part 601 can enter the area related to the positioning hole 203 through this connecting hole 205 with a smaller diameter, thereby realizing the unlocking operation of the positioning bead 5. Since the diameter of the connecting hole 205 is smaller than the diameter of the positioning hole 203, this requires that the unlocking part 601 must be inserted into the connecting hole 205 accurately. This design can ensure the accuracy of the unlocking operation and avoid misoperation. The smaller connecting hole 205 limits the operation of the positioning hole 203 by unauthorized objects or tools to a certain extent. General tools may not be able to reach the positioning hole 203 through the connecting hole 205, thereby preventing the illegal opening of the metering box. The design of the anti-slip portion 202 and the communicating hole 205 maintains the integrity of the overall structure of the meter box while realizing the unlocking function. The appearance or structure of the meter box will not become complicated or fragile due to the existence of the security structure.
