Description

Technical Field

[0001] This utility model relates to the field of metering box technology, and more specifically, to a cover plate structure and an electricity metering box. Background Technology

[0002] Currently, when operators open the switch cover of the metering box to maintain or operate the internal structure, they need to use tools to unscrew the screws at the bottom of the switch cover and then manually flip it upwards. At the same time, they need to keep the switch cover in the open position at all times to prevent it from closing under gravity. In addition, they need to operate the internal structure with one hand, and in some specific situations, two people are even needed to operate it, making the maintenance process quite cumbersome. Utility Model Content

[0003] The present invention aims to at least solve the technical problem of cumbersome maintenance operations in the prior art or related technologies.

[0004] In view of this, an embodiment of the first aspect of the present invention provides a cover plate structure.

[0005] A second aspect of this utility model provides an energy metering box.

[0006] To achieve the above objectives, embodiments of this utility model provide a cover structure for an electricity metering box. The cover structure includes: a plate body with at least one switch slot on the plate body, the bottom of the switch slot having an opening for the circuit breaker of the electricity metering box to extend out; a switch cover rotatably connected to the plate body to open and close the switch slot; a reset member, one end of which is connected to the plate body and the other end of which is connected to the switch cover; a first latching member disposed on the switch cover; and a second latching member disposed on the plate body. When the switch cover is rotated relative to the switch slot to the locked position, the first latching member and the second latching member are latched together, and the reset member is in a stretched state.

[0007] According to the cover structure proposed in this utility model, the normal opening and closing function of the switch cover is realized, and it can remain stable under the action of the reset member when closed to the locking position. The circuit breaker or other equipment in the switch slot can be operated with one hand, which effectively reduces the operation difficulty of the operator and thus improves the maintenance efficiency.

[0008] Specifically, the cover structure includes a plate body, a switch cover, a reset component, a first latching component, and a second latching component. The plate body has one or more switch slots, each with an opening at the bottom. The switch slots provide space for the circuit breaker, allowing it to be installed inside the energy metering box and isolated from external operations, protecting the circuit breaker from external interference. The opening at the bottom of the slot allows the operating parts of the circuit breaker (such as a handle) to extend, facilitating user operation such as connecting or disconnecting the circuit.

[0009] The first latching element is located on the switch cover, and the second latching element is located on the plate body. When the switch cover rotates relative to the switch slot to the locked position, the first and second latching elements engage. In the closed state, the switch cover can be stably held in the locked position, preventing accidental opening due to external vibration, misoperation, or other reasons. The latching action of the latching elements provides additional fixing force, enhancing the safety and reliability of the cover structure. In the locked position, the reset element is in a stretched state, meaning that it stores a certain amount of elastic potential energy. When it is necessary to open the switch cover, after overcoming the latching force of the latching elements, the elastic restoring force of the reset element can assist in opening the switch cover without manual operation by the user.

[0010] In some technical solutions, the switch cover may optionally include: a cover plate, one end of which is provided with a rotating part that is rotatably connected to the plate body, and the other end of which is provided with a first snap-fit ​​member.

[0011] In this technical solution, the switch cover mainly includes a cover plate as the main body, which serves to shield and protect the switch slot. One end of the cover plate has a rotating part, and the other end has a first locking member. The rotating part is mainly used to achieve a rotatable connection with the plate body, allowing the cover plate to rotate relative to the plate body, thereby realizing the opening and closing operation of the switch cover. The first locking member is located at the other end of the cover plate and is used to cooperate with a second locking member on the plate body. When the switch cover is closed to the locked position, it is locked in place, ensuring the stability and safety of the switch cover in the closed state.

[0012] The rotating part serves as the connection between the cover and the plate, enabling the cover to rotate and allowing it to open and close flexibly, facilitating user operation, while ensuring the stability of the connection between the cover and the plate.

[0013] In some technical solutions, optionally, the first latching component specifically includes: a latching plate, which is spaced apart from the cover plate and connected to the side of the cover plate facing the switch groove; wherein, when the switch cover is rotated to the locked position, the latching plate is in contact with the bottom of the switch groove.

[0014] In this technical solution, the first snap-fit ​​component includes a snap plate, which is spaced apart from the cover plate and is used to fit against the bottom of the switch slot in the locked position. That is, the second snap-fit ​​component can directly pass through the snap plate and snap the snap plate to achieve the snap-fit ​​and fixation function.

[0015] It is understandable that, due to the spacing between the card plate and the cover plate, the middle part provides a space for the structure of the second snap-fit ​​component, so as to achieve precise snap-fit ​​positioning.

[0016] In some technical solutions, optionally, the first snap-fit ​​element is hole-shaped, and the second snap-fit ​​element includes a connected support portion and a snap-fit ​​portion. One end of the support portion is connected to the plate body, and the other end of the support portion is provided with a snap-fit ​​portion. In this case, when the switch cover is rotated to the locked position, the snap-fit ​​portion passes through the first snap-fit ​​element to realize the snap-fit ​​between the first snap-fit ​​element and the second snap-fit ​​element.

[0017] In this technical solution, the first latching component has a hole-like structure, meaning it is perforated. The second latching component includes a support portion, one end of which is connected to the plate body, and the other end has a latching portion. The support portion stably fixes the latching portion to the plate body. The latching portion is located at the other end of the support portion, allowing it to interact effectively with the first latching component when the switch cover is rotated to the locked position. It can be understood that in this solution, when the switch cover is rotated to the locked position, the latching portion of the second latching component passes through the first latching component (hole-like structure). This latching method utilizes the shape fit of the two components. After the latching portion enters the hole-like first latching component, it forms a mechanical constraint, thereby achieving the latching between the first and second latching components. This effectively fixes the switch cover in the locked position, preventing it from disengaging from the closed state due to unexpected external forces (such as vibration, accidental contact, etc.), ensuring the safety and stability of the internal equipment of the power metering box, such as circuit breakers.

[0018] The engagement of the first, perforated latching element and the second, latching element with a latching portion provides guidance during the latching process. As the cover closes, the latching portion accurately aligns with the first latching element (perforated structure), ensuring accurate latching every time. This helps improve the overall reliability of the cover structure and reduces the risk of equipment failure due to inaccurate latching.

[0019] In some technical solutions, optionally, the projection size of the snap-fit ​​part on the plane of the plate is variable, and the snap-fit ​​part includes snap-fit ​​forms and mating forms with different deformations; wherein, when the snap-fit ​​part is in the snap-fit ​​form, the projection of the snap-fit ​​part on the plate covers the projection of the support part on the plate, and when the snap-fit ​​part is in the mating form, the projection of the first snap-fit ​​member on the plate covers the projection of the snap-fit ​​part on the plate.

[0020] In this technical solution, the projection size of the latching part on the plane of the plate is variable. The latching part has the characteristic of being able to change its size on the plate plane. Depending on its shape, the latching part is divided into a latching form and a mating form. In the latching form, the projection of the latching part on the plate covers the projection of the supporting part on the plate, meaning the size of the latching part is larger, enabling a firm latching with the first latching member. In the mating form, the projection of the first latching member on the plate covers the projection of the latching part on the plate, indicating that the size of the latching part is relatively smaller, allowing it to smoothly pass through the first latching member and achieve the closing action of the switch cover.

[0021] The variable projection size of the snap-fit ​​part allows it to take on different forms at different operating stages, thus meeting the needs of snap-fit ​​and mating. When it is necessary to snap-fit ​​and fix the switch cover, the snap-fit ​​part changes to a snap-fit ​​form to ensure the stability of the switch cover; when it is necessary to close the switch cover, the snap-fit ​​part changes to a mating form to facilitate the passage of the first snap-fit ​​member and complete the closing action.

[0022] In some technical solutions, optionally, the board body is provided with a display part and a switch part in the first direction, the switch slot is provided in the switch part, one end of the switch cover along the first direction is rotatably connected to the switch slot, the first snap-fit ​​member is provided at the other end of the switch cover along the first direction, and the reset member extends along the first direction, with one end of the reset member connected to the side surface of the switch cover away from the switch slot.

[0023] In this technical solution, the panel includes a display section and a switch section. By restricting the display section and switch section to be arranged along a first direction, the display and operation functions of the energy metering box are clearly spatially divided. The display section is used to show energy metering information, such as energy consumption, voltage, and current, for user convenience. The switch section is the area for accommodating the circuit breaker and performing operational control. The fact that both are arranged in the same direction helps improve the logicality and convenience of operation.

[0024] In addition, one end of the switch cover along the first direction is rotatably connected to the switch slot, so that the switch cover can rotate relative to the switch slot around the connection point, thereby realizing the opening and closing operation of the switch cover. This ensures that the switch cover has a stable fulcrum during the opening and closing process, making the movement trajectory relatively fixed, which is convenient for operation and control.

[0025] The reset member extends along a first direction, with one end connected to the side surface of the switch cover away from the switch slot, enabling the reset member to function during the opening and closing of the switch cover. When the switch cover is closed and in the locked position, the reset member is stretched, storing elastic potential energy; when the external force disappears, the elastic potential energy of the reset member causes the switch cover to return to the open position.

[0026] It should be added that the layout of the display section and the switch section along the first direction conforms to the user's operating habits. After viewing the power information on the display section, the user can conveniently operate the switch section in the same direction, reducing the complexity and time required for operation.

[0027] The design of the switch cover, with a rotating connection at one end and a snap-fit ​​at the other, ensures the stability of the switch cover during opening and closing. During opening, the rotating connection provides a stable pivot point; during closing, the snap-fit ​​mechanism ensures that the switch cover closes tightly, preventing accidental opening.

[0028] In some technical solutions, optionally, the reset element is a spring. When the first latching element and the second latching element are disengaged, the reset element retracts to drive the switch cover to rotate relative to the switch slot to the open position.

[0029] In this technical solution, the reset element is a spring, which has a certain degree of elasticity. When the first and second latching parts are disengaged, the spring is no longer restricted by tension and will quickly contract. The contraction force of the spring will cause the switch cover to rotate relative to the switch slot, so that it automatically reaches the open position, which reduces the number of steps required for the user to manually open the switch cover and improves the convenience and efficiency of operation.

[0030] It is understandable that using a spring to automatically open the lid can complete the opening and closing action in a short time. Especially when frequent operation is required, it can significantly save operation time and improve work efficiency.

[0031] Among them, the mechanical properties of the spring are relatively stable, which can provide reliable contraction force, ensuring that the cover can be smoothly rotated to the open position, reducing the possibility of failure to open the cover due to improper operation or other factors.

[0032] In some technical solutions, optionally, a support column is also included, located at the bottom of the switch slot, such that when the switch cover is rotated relative to the switch slot to the locked position, the support column is in contact with or has a gap with the wall surface of the switch cover facing the bottom of the slot.

[0033] In this technical solution, a support column is provided at the bottom of the switch slot. When the switch cover is rotated to the locked position, the support column fits against the wall of the side of the switch cover facing the bottom of the slot, which can provide additional support for the switch cover, enhance the stability of the entire structure, and reduce the shaking or deformation of the switch cover during use.

[0034] In some technical solutions, optionally, a guide plate is also included, disposed on one side wall of the switch cover facing the bottom of the switch slot, and the guide plate extends along a first direction.

[0035] In this technical solution, a guide plate is disposed on the side wall of the switch cover facing the bottom of the switch slot, allowing the guide plate to directly interact with the internal structure of the switch slot. The guide plate extends along a first direction, aligning with the orientation of the display and switch portions on the panel, and conforming to the overall layout of the structure in the first direction.

[0036] The guide plate, by extending along a first direction, provides accurate directional guidance for the switch cover during its opening and closing rotation relative to the switch slot. Due to the limited internal space and compact layout of the components in the energy metering box, the guide plate prevents the switch cover from shifting or wobbling during rotation, ensuring that each opening and closing action of the switch cover follows a predetermined trajectory.

[0037] The guide plate reduces frictional resistance and unnecessary obstruction during the rotation of the switch cover. This makes the movement of the switch cover more linear and smooth, providing users with a more relaxed and fluid operating experience. Especially in situations involving frequent opening and closing of the switch cover, this smoothness improves operational efficiency and reduces wear on components.

[0038] An embodiment of the second aspect of this application provides an electricity metering box, comprising: a box body, a circuit breaker disposed inside the box body; any of the aforementioned cover structures, disposed on the box body, and at least a portion of the circuit breaker extending through an opening.

[0039] The assembly system provided in this application includes a housing and a cover structure. The housing, as the main body of the electricity metering box, provides space for the installation and protection of internal components such as circuit breakers. The circuit breaker is installed inside the housing and is used to control the on / off state of the circuit, thus providing protection and control for the circuit.

[0040] Circuit breakers control the opening and closing of circuits. When abnormal conditions such as overload or short circuit occur in the circuit, the circuit breaker can automatically trip and disconnect the circuit, effectively protecting the circuit and equipment and avoiding damage and safety accidents caused by circuit faults.

[0041] Since the electricity metering box includes any of the above-mentioned cover structures, it has the beneficial effects of any of the above-mentioned cover structures, which will not be elaborated here.

[0042] Additional aspects and advantages of this invention will become apparent in the description that follows, or may be learned by practice of this invention. Attached Figure Description

[0052] To better understand the above-mentioned objectives, features, and advantages of the embodiments of this utility model, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0053] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, embodiments of the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0054] The following reference Figures 1 to 6 Some embodiments of the present invention are described below.

[0055] like Figure 1 As shown, this embodiment provides a cover structure 100, which realizes the normal opening and closing function of the switch cover 104, and can remain stable under the action of the reset member 106 when closed to the locking position. The circuit breaker 2022 or other equipment in the switch slot 1022 can be operated with one hand, which effectively reduces the operation difficulty of the operator and improves the maintenance efficiency.

[0056] Specifically, such as Figure 1 and Figure 2As shown, the cover structure 100 includes a plate 102, a switch cover 104, a reset member 106, a first latching member 1082, and a second latching member 1084. The plate 102 has one or more switch slots 1022, each with an opening 1024 at its bottom. The switch slots 1022 provide space for the circuit breaker 2022, allowing it to be installed inside the energy metering box 200 and isolated from external operations, protecting the circuit breaker 2022 from external interference. The opening 1024 at the bottom of the slot allows the operating parts of the circuit breaker 2022 (such as a handle) to extend, facilitating user operation such as connecting or disconnecting the circuit.

[0057] The switch cover 104 is rotatably connected to the plate 102, allowing the switch cover 104 to rotate relative to the plate 102, thereby enabling the opening and closing of the switch slot 1022. This connection method is simple and reliable, ensuring the normal operation of the switch cover 104 while reducing the complexity of components and lowering costs. The rotatable connection can be achieved through hinges or other means, ensuring a stable movement trajectory for the switch cover 104 during opening and closing. The two ends of the reset member 106 are connected to the plate 102 and the switch cover 104 respectively, allowing the reset member 106 to undergo elastic deformation during the movement of the switch cover 104. When the switch cover 104 is in the locked position, such as... Figure 3 As shown, at this time, the first latching member 1082 and the second latching member 1084 are engaged, causing the switch cover 104 to be fastened to the switch slot 1022. At this time, the reset member 106 is in a stretched state. After unlocking it, as shown... Figure 4 As shown, when the external force disappears, the reset member 106 will pull the switch cover 104 to rotate relative to the switch slot 1022 to the open position due to its own elastic restoring force. At this time, the operator does not need to hold the switch cover 104 and can operate the exposed switch slot 1022 with both hands, thereby effectively improving the convenience of operation.

[0058] The first latching member 1082 is located on the switch cover 104, and the second latching member 1084 is located on the plate 102. When the switch cover 104 rotates relative to the switch slot 1022 to the locked position, the first latching member 1082 and the second latching member 1084 engage. In the closed state, the switch cover 104 can be stably held in the locked position, preventing the switch cover 104 from being accidentally opened due to external vibration, misoperation, or other reasons. The latching action of the latching members provides additional fixing force, enhancing the safety and reliability of the cover structure 100. In the locked position, the reset member 106 is in a stretched state, which means that the reset member 106 stores a certain amount of elastic potential energy. When it is necessary to open the switch cover 104, after overcoming the latching force of the latching members, the elastic restoring force of the reset member 106 can assist the opening action of the switch cover 104 without manual operation by the user.

[0059] The second snap-fit ​​component 1084 has a larger size on the side closer to the plate 102 and a smaller size on the side farther away from the plate 102, forming a shape that is smaller at the top and larger at the bottom, with a slope and an open space in the middle.

[0060] In some embodiments, the switch cover 104 may optionally include a cover plate 1042 as the main body, which serves to cover and protect the switch slot 1022. One end of the cover plate 1042 has a rotating part 1044, and the other end has a first latching member 1082. The rotating part 1044 is mainly used to achieve a rotatable connection with the plate body 102, allowing the cover plate 1042 to rotate relative to the plate body 102, thereby realizing the opening and closing operation of the switch cover 104. The first latching member 1082 is located at the other end of the cover plate 1042 and is used to cooperate with the second latching member 1084 on the plate body 102. When the switch cover 104 is closed to the locked position, it is latched and fixed, ensuring the stability and safety of the switch cover 104 in the closed state.

[0061] It is understandable that the cover plate 1042 can effectively shield the switch slot 1022, prevent foreign objects from entering, protect internal components such as the circuit breaker 2022, reduce the impact of external factors on the inside of the power metering box 200, and improve the reliability and safety of the equipment.

[0062] The rotating part 1044 serves as the part connecting the cover plate 1042 and the plate body 102, realizing the rotation function of the switch cover 104, so that the switch cover 104 can be opened and closed flexibly, making it convenient for users to operate, while ensuring the connection stability between the switch cover 104 and the plate body 102.

[0063] The first latching member 1082 and the second latching member 1084 cooperate to latch when the switch cover 104 is closed to the locked position, keeping the switch cover 104 in the closed state. This enhances the stability of the switch cover 104 in the closed state, prevents the switch cover 104 from being opened accidentally, and improves the overall safety of the electricity metering box 200. At the same time, by using the latching method, the cover can be unlocked directly when the user performs the opening operation, and then the cover can be opened automatically under the action of the reset member 106, reducing the difficulty of operation for the operator.

[0064] In some embodiments, the first snap-fit ​​member 1082 may optionally include a snap-fit ​​plate 1083, which is spaced apart from the cover plate 1042 and is used to fit against the bottom of the switch slot 1022 in the locked position. That is, the second snap-fit ​​member 1084 can directly pass through the snap-fit ​​plate 1083 and snap the snap-fit ​​plate 1083 to achieve the snap-fit ​​and fixation function.

[0065] It is understandable that, since the card plate 1083 and the cover plate 1042 are spaced apart, the middle part provides a space for the structure of the second card connector 1084, so as to achieve precise card positioning.

[0066] In some embodiments, optionally, such as Figure 6 As shown, the first latching member 1082 has a hole-like structure, meaning it is perforated. The second latching member 1084 includes a support portion 1085, one end of which is connected to the plate 102, and the other end has a latching portion 1086. The support portion 1085 stably fixes the latching portion 1086 to the plate 102. The latching portion 1086 is located at the other end of the support portion 1085, allowing it to effectively interact with the first latching member 1082 when the switch cover 104 is rotated to the locked position. It can be understood that in this design, when the switch cover 104 is rotated to the locked position, the latching portion 1086 of the second latching member 1084 passes through the first latching member 1082 (hole-like structure). This snap-fit ​​method utilizes the shape matching of two components. After the snap-fit ​​part 1086 enters the hole-shaped first snap-fit ​​member 1082, it forms a mechanical constraint, thereby realizing the snap-fit ​​between the first snap-fit ​​member 1082 and the second snap-fit ​​member 1084. This can effectively fix the switch cover 104 in the locked position and prevent the switch cover 104 from falling out of the closed state due to unexpected external forces (such as vibration, accidental contact, etc.), thus ensuring the safety and stability of the internal equipment of the power metering box 200, such as the circuit breaker 2022.

[0067] The engagement of the perforated first latching member 1082 and the second latching member 1084 with a latching portion 1086 provides guidance during the latching process. During the closing of the switch cover 104, the latching portion 1086 accurately aligns with the first latching member 1082 (perforated structure), ensuring accurate latching each time. This helps improve the reliability of the entire cover structure 100 and reduces the risk of equipment failure due to inaccurate latching.

[0068] This snap-fit ​​connection tightly links the switch cover 104 and the plate 102 together, making the cover structure 100 a single unit. During normal use of the electricity metering box 200, whether it is vibration during transportation or external forces during daily operation, this snap-fit ​​structure can maintain the integrity of the cover structure 100, preventing the switch cover 104 from loosening or falling off, thereby protecting the electrical components inside the electricity metering box 200 from interference from external factors.

[0069] In some embodiments, optionally, the projection size of the latching portion 1086 on the plane of the plate 102 is limited to be variable. The latching portion 1086 has the characteristic of being able to change its size on the plane of the plate 102. The latching portion 1086 is divided into a latching mode and a mating mode according to its shape. In the latching mode, the projection of the latching portion 1086 on the plate 102 covers the projection of the support portion 1085 on the plate 102. That is, the size of the latching portion 1086 is larger at this time, which can achieve a firm latching with the first latching member 1082. In the mating mode, the projection of the first latching member 1082 on the plate 102 covers the projection of the latching portion 1086 on the plate 102. This indicates that the size of the latching portion 1086 is relatively smaller, so that it can pass smoothly through the first latching member 1082 to realize the closing action of the switch cover 104.

[0070] The variable projected size of the latching part 1086 allows it to take on different forms at different operating stages, thus meeting the needs of latching and mating. When it is necessary to latch and fix the switch cover 104, the latching part 1086 changes to a latching form to ensure the stability of the switch cover 104; when it is necessary to close the switch cover 104, the latching part 1086 changes to a mating form to facilitate passing through the first latching member 1082 and completing the closing action.

[0071] When the snap-fit ​​part 1086 switches from snap-fit ​​mode to mating mode, the user generally needs to apply a certain external force to it. The specific external force may include, but is not limited to, moving from both sides to the middle, or moving in one direction from left to right or from right to left.

[0072] It is understandable that during the process of closing the switch cover 104, the engagement form of the snap-fit ​​part 1086 reduces interference with the first snap-fit ​​part 1082, making the operation easier. When it is necessary to fix the switch cover 104, the snap-fit ​​form can provide a reliable fixing effect without the need for additional complicated operations.

[0073] In some embodiments, the panel 102 optionally includes a display section 1032 and a switch section 1034. By restricting the display section 1032 and the switch section 1034 to be arranged along a first direction, the display and operation functions of the energy metering box 200 are clearly spatially partitioned. The display section 1032 is used to display energy metering-related information, such as energy consumption, voltage, and current, for user convenience. The switch section 1034 is the area for accommodating the circuit breaker 2022 and performing operation control. The fact that both are arranged in the same direction helps improve the logic and convenience of operation.

[0074] Based on this, the switch slot 1022 is set in the switch section 1034. Since the switch section 1034 is mainly related to the operation of the circuit breaker 2022, the switch slot 1022 provides suitable space for the circuit breaker 2022, so that the circuit breaker 2022 can perform corresponding actions in the slot. At the same time, the existence of the switch slot 1022 also provides a basis for the setting of the switch cover 104.

[0075] In addition, one end of the switch cover 104 along the first direction is rotatably connected to the switch groove 1022, so that the switch cover 104 can rotate relative to the switch groove 1022 around the connection point, thereby realizing the opening and closing operation of the switch cover 104. This ensures that the switch cover 104 has a stable fulcrum during the opening and closing process, making the movement trajectory relatively fixed, which is convenient for operation and control.

[0076] The first latching member 1082 is located at the other end of the switch cover 104 along the first direction. When the switch cover 104 rotates around the rotation connection point to the closed position, the first latching member 1082 at the other end can engage with the second latching member 1084 on the plate 102, thereby firmly fixing the switch cover 104 in the closed state. The design of providing a rotation connection point and a latching member at both ends of the switch cover 104 makes the structure of the switch cover 104 more stable and improves the latching effect.

[0077] Furthermore, the reset member 106 extends along the first direction, and one end of it is connected to the side surface of the switch cover 104 away from the switch slot 1022, so that the reset member 106 can function during the opening and closing of the switch cover 104. When the switch cover 104 is closed and in the locked position, the reset member 106 is stretched and stores elastic potential energy; when the external force disappears, the elastic potential energy of the reset member 106 will cause the switch cover 104 to return to the open position.

[0078] It should be added that the layout of the display unit 1032 and the switch unit 1034 along the first direction conforms to the user's operating habits. After viewing the power information of the display unit 1032, the user can conveniently operate the switch unit 1034 in the same direction, reducing the complexity and time of operation.

[0079] The design of the switch cover 104, with a rotating connection at one end and a snap-fit ​​at the other, ensures the stability of the switch cover 104 during opening and closing. During opening, the rotating connection point provides a stable pivot point; during closing, the snap-fit ​​mechanism ensures that the switch cover 104 can be tightly closed, preventing accidental opening.

[0080] It is understandable that the snap-fit ​​of the first snap-fit ​​component 1082 and the second snap-fit ​​component 1084 can firmly fix the switch cover 104 in the closed position, protect the circuit breaker 2022 and other equipment in the switch slot 1022 from external interference, and also improve the safety of the power metering box 200.

[0081] In some embodiments, the reset member 106 may optionally be a spring with a certain elasticity. When the first latching member 1082 and the second latching member 1084 are disengaged, the spring is no longer restricted by tension and will quickly contract. The contraction force of the spring will drive the switch cover 104 to rotate relative to the switch slot 1022, so that it automatically reaches the open position, which can reduce the number of steps for the user to manually open the switch cover 104 and improve the convenience and efficiency of operation.

[0082] It is understandable that using a spring to achieve automatic opening of the cover can complete the opening action of the cover 104 in a short time. Especially when frequent operation is required, it can significantly save operation time and improve work efficiency.

[0083] Among them, the mechanical properties of the spring are relatively stable, which can provide reliable contraction force, ensuring that the switch cover 104 can be smoothly rotated to the open position, reducing the possibility of failure to open the cover due to improper human operation or other factors.

[0084] In some embodiments, optionally, a support column 110 is provided at the bottom of the switch slot 1022. When the switch cover 104 is rotated to the locked position, the support column 110 fits against the wall surface of the switch cover 104 on the side facing the bottom of the slot, which can provide additional support for the switch cover 104, enhance the stability of the entire structure, and reduce the shaking or deformation of the switch cover 104 during use.

[0085] Even if there are manufacturing or assembly errors between the switch cover 104 and the switch slot 1022, the support column 110 can still play a certain adjustment role. If there is a gap between the support column 110 and the wall of the switch cover 104, this gap can accommodate these errors to a certain extent, allowing the switch cover 104 to still smoothly complete the opening and closing action and remain relatively stable in the locked position.

[0086] When the switch cover 104 is closed and in the locked position, the support column 110 can share some of the pressure from the switch cover 104, making the force on the switch groove 1022 more even and extending the service life of the switch groove 1022 and the switch cover 104.

[0087] By enhancing structural stability and distributing stress, the support column 110 helps improve the overall safety of the electricity metering box 200 and reduces potential safety hazards caused by the instability of the switch cover 104.

[0088] In some embodiments, optionally, a guide plate 112 is disposed on a side wall of the switch cover 104 facing the bottom of the switch slot 1022, so that the guide plate 112 can directly interact with the internal structure of the switch slot 1022. The guide plate 112 extends along a first direction, which is the same as the orientation of the display portion 1032 and the switch portion 1034 on the plate 102, and conforms to the layout of the entire structure in the first direction.

[0089] The guide plate 112, by utilizing its extension along a first direction, provides accurate directional guidance for the switch cover 104 during its opening and closing rotation relative to the switch slot 1022. Due to the limited internal space and compact layout of the components in the energy metering box 200, the guide plate 112 prevents the switch cover 104 from shifting or wobbling during rotation, ensuring that each opening and closing action of the switch cover 104 follows a predetermined trajectory.

[0090] For example, when the switch cover 104 is closed, the guide plate 112 can guide the switch cover 104 to accurately cooperate with the various components (such as the support column 110, the snap-fit ​​component, etc.) of the switch slot 1022, so as to avoid problems such as component collision and snap-fit ​​failure caused by inaccurate movement trajectory.

[0091] The presence of the guide plate 112 reduces frictional resistance and unnecessary obstruction during the rotation of the switch cover 104. This makes the movement of the switch cover 104 more linear and smooth, providing users with a more relaxed and fluid operating experience. Especially in situations involving frequent opening and closing of the switch cover 104, this smoothness improves operating efficiency and reduces wear on components.

[0092] When the switch cover 104 is closed, the guide plate 112 can precisely position the switch cover 104 to the locked position. Since the guide plate 112 extends along the first direction, it can cooperate with the corresponding structure in the switch slot 1022 (such as the positioning structure on the slot wall or other components related to the first direction) to ensure that the first latching member 1082 and the second latching member 1084 can be accurately latched, and that the support column 110 and the wall of the switch cover 104 achieve a predetermined fit or gap state.

[0093] When the switch cover 104 is in the closed state, the guide plate 112 can help maintain a stable relative positional relationship between the switch cover 104 and the switch slot 1022.

[0094] like Figure 5As shown, in another embodiment of this application, an electricity metering box 200 is provided, including: a box body 202, a circuit breaker 2022 is provided inside the box body 202; a cover plate structure 100 of any of the above embodiments is provided on the box body 202, and at least part of the circuit breaker 2022 extends out through the opening 1024.

[0095] The assembly system includes a housing 202 and a cover structure 100. The housing 202, as the main body of the electricity metering box 200, provides space for the installation and protection of internal components such as the circuit breaker 2022. The circuit breaker 2022 is installed inside the housing 202 and is used to control the on / off state of the circuit, thus providing protection and control for the circuit.

[0096] The 2022 circuit breaker can control the opening and closing of the circuit. When an abnormal situation such as overload or short circuit occurs in the circuit, the 2022 circuit breaker can automatically trip and disconnect the circuit, effectively protecting the circuit and equipment and avoiding damage and safety accidents caused by circuit faults.

[0097] In summary, the enclosure 202 provides a good protective environment for the internal components, the circuit breaker 2022 ensures the safe operation of the circuit, and the cover structure 100 facilitates the operation and maintenance of the circuit breaker 2022, while also ensuring the sealing and safety of the enclosure 202 to a certain extent.

[0098] Since the electricity metering box 200 includes any of the above-mentioned cover structures 100, it has the beneficial effects of any of the above-mentioned cover structures 100, which will not be elaborated here.

[0099] In one specific embodiment, an automatic flip-top metering box (i.e., an electricity metering box) is defined. Existing metering boxes require manually unscrewing screws to open the switch cover. Furthermore, after opening the switch cover, operating the interior requires one hand to hold the cover to prevent it from falling, while the other hand operates it. The operation process is cumbersome, time-consuming, labor-intensive, and inconvenient. In certain situations, two people are needed to operate it: one to hold the switch cover and the other to operate it with both hands. After operation, the cover needs to be closed and the screws tightened.

[0100] The metering box uses an automatic flip-top mechanism, employing self-locking latches (i.e., the first and second latches) and a tension spring structure (i.e., the reset mechanism). To open the lid, simply pinch both ends of the self-locking latch (i.e., the second latch), and the spring will pull the lid open, completing the automatic flip-top mechanism. To close the lid, press the lid down until it reaches the self-locking latch, which will lock the lid in place, completing the closing process.

[0101] The automatic lid-opening mechanism of the metering box mainly consists of three parts. One end of the tension spring (i.e., the reset component) is installed in the lid fixing position of the main body cover (i.e., the plate), and the other end of the tension spring is installed in the switch cover fixing position. A self-locking buckle (i.e., the second latching component) is added to the main body cover. The self-locking buckle has a sloping structure, wider at the bottom than at the top, with a gap in the middle. It utilizes the elasticity of the plastic to create a self-locking structure. When the lid is closed, the latching groove of the switch cover (i.e., the first latching component) retracts the self-locking buckle in the main body cover inward. After being pressed into place, the plastic springs back, completing the self-locking lid closure. When the lid needs to be opened, the self-locking buckle in the main body cover is squeezed by hand, and the tension spring pulls the switch cover open, completing the automatic lid opening.

[0102] Based on the cover structure and power metering box provided in this application, the circuit breaker or other equipment in the switch slot can be operated with one hand through the reset component and the snap-fit ​​relationship between the switch cover and the plate, effectively reducing the difficulty of operation for operators and thus improving maintenance efficiency.
