Description

Technical Field

[0001] Embodiments of the present application relate to the field of power metering, and more particularly to an electric meter. Background Art

[0002] In the field of power metering, an electric meter can measure and record various electrical quantities such as current and voltage, and has been widely used in daily life and production activities. During the installation process of the electric meter, operations such as positioning and wiring are required. Therefore, the structural optimization of the electric meter has become the key to improving the user interactivity and convenience of the electric meter.

[0003] The wiring part on the electric meter is used to connect with the electric wire and needs to be protected by the meter cover. To facilitate user operation, the existing meter cover is usually set as a flip cover. The user only needs to open the flip cover when wiring and close the flip cover after wiring.

[0004] However, the existing flip cover usually uses a buckle structure to realize the closing of the flip cover. When the user closes and opens the flip cover, they need to perform locking and unlocking actions that match the buckle structure. And if the user opens the flip cover through the wrong unlocking action, it is very likely to damage the flip cover. Therefore, how to improve the convenience of opening and closing the flip cover has become a technical problem to be solved. Summary of the Utility Model

[0005] In view of the above problems, embodiments of the present application provide an electric meter, in which the locking and unlocking of the flip cover can be automatically completed when the flip cover is closed and opened, improving the convenience of operation.

[0006] Embodiments of the present application provide an electric meter, which includes: an electric meter body and a flip cover. The flip cover is rotatably arranged on the electric meter body, and a first engaging part is arranged on the flip cover. A second engaging part corresponding to the first engaging part is arranged on the electric meter body, and the first engaging part can form an interference fit with the second engaging part when the flip cover is closed to keep the flip cover in the closed position. The locking and unlocking of the flip cover can be automatically completed when the flip cover is closed and opened, without specific locking and unlocking actions, improving the convenience of user operation.

[0007] Optionally, the first engaging part is a protruding part, and the second engaging part is a groove corresponding to the protruding part. The protruding part can extend into the groove and form an interference fit with the inner wall of the groove when the flip cover is closed. The arrangement of the protruding part and the groove makes the structures of the first engaging part and the second engaging part simple, occupy less space, and are convenient to process.

[0008] Optionally, an embedding part is arranged on the protruding part, and an embedding groove corresponding to the embedding part is arranged on the inner wall of the groove. The embedding part can slide into the embedding groove along the inner wall of the groove when the flip cover is closed, and the embedding part can slide out of the embedding groove when the flip cover is opened. The embedding part can increase the resistance when the interference fit is released, thereby improving the reliability of the flip cover when it is engaged.

[0009] Optionally, the outer surface of the insert is arc-shaped, and / or the surface of the groove body of the insertion groove is arc-shaped. The insert can smoothly extend into or slide out of the insertion groove under the guiding action of the arc-shaped outer surface, thereby improving the smoothness when the flip cover is buckled and opened.

[0010] Optionally, the first engaging portion is a groove, and the second engaging portion is a convex portion corresponding to the groove. The convex portion can extend into the groove when the flip cover is buckled and form an interference fit with the inner wall of the groove. The settings of the convex portion and the groove make the structures of the first engaging portion and the second engaging portion simple, occupy less space, and are convenient for processing.

[0011] Optionally, the first side of the flip cover is rotatably connected to the electricity meter body. A first blocking portion is provided on the first side of the flip cover, and a second blocking portion corresponding to the first blocking portion is provided on the electricity meter body. The first blocking portion can abut against the second blocking portion as the flip cover is opened to block the buckling of the flip cover. The first blocking portion and the second blocking portion can block the buckling of the flip cover after the flip cover is opened, so that the flip cover can remain in the open state after being opened, facilitating operations such as installation and inspection of the internal components of the electricity meter by the user, and further improving the convenience during user operation.

[0012] Optionally, the first blocking portion is the first edge on the first side of the flip cover, and the second blocking portion is an abutting groove corresponding to the first edge. The first edge can be snapped into the abutting groove as the flip cover is opened to block the buckling of the flip cover through the groove wall of the abutting groove. This structure makes the flip cover simple in structure, convenient for processing, and can ensure the reliability of blocking the buckling of the flip cover.

[0013] Optionally, a guiding portion is provided at the opening of the abutting groove, and the guiding portion is located on the moving path of the first edge, so that the first edge slides into the abutting groove under the guiding action of the guiding portion. The setting of the guiding portion enables the first edge to smoothly snap into the abutting groove, making the opening process of the flip cover smoother.

[0014] Optionally, the first blocking portion is an abutting groove provided on the first side of the flip cover, and the second blocking portion is provided as a convex structure corresponding to the abutting groove. The abutting groove can catch the convex structure as the flip cover is opened to block the buckling of the flip cover through the convex structure. The first blocking portion is set as an abutting groove, and the second blocking portion is set as a convex structure. The cooperation between the two can reliably and effectively block the buckling of the flip cover.

[0015] Optionally, a first lead seal is provided on the flip cover, and a second lead seal is provided on the electricity meter body. The lead seal wire passes through the first lead seal and the second lead seal in sequence to seal the flip cover and the electricity meter body. After the first lead seal and the second lead seal are sealed with the lead seal wire, it can prevent the electricity meter from being opened by unauthorized personnel for improper operations, improving the safety performance of the electricity meter.

[0016] In the electric meter provided by the embodiment of the present application, a first engaging portion is provided on the flip cover, and a second engaging portion corresponding to the first engaging portion is provided on the electric meter body, and the first engaging portion can form an interference fit with the second engaging portion as the flip cover is buckled. When the user buckles the flip cover, only a single buckling action needs to be performed on the flip cover to make the first engaging portion of the flip cover and the second engaging portion form an interference fit, so that the flip cover is locked to form a protection. When the user opens the flip cover, only a single opening action needs to be performed on the flip cover to release the interference fit between the first engaging portion and the second engaging portion, so as to release the lock of the flip cover and open the flip cover. Therefore, in this kind of electric meter, the locking and unlocking of the flip cover can be automatically completed when the flip cover is buckled and opened, without specific locking and unlocking actions, and the operation is more convenient and the convenience is higher.

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0041] The electric meter provided in this embodiment is as Figure 1 and Figure 2 shown. Figure 1 It is a schematic structural diagram when the flip cover of the electric meter provided in the embodiment of the present application is opened. Figure 2 It is a schematic structural diagram when the flip cover of the electric meter provided in the embodiment of the present application is closed. As shown in the figure, the electric meter includes: an electric meter body 20 and a flip cover 10.

[0042] The electric meter body 20 is a frame structure for installing components such as a display module, a metering module, wires, and the flip cover 10. Moreover, on the electric meter body 20, structures such as grooves, cavities, through holes, and bosses can be provided corresponding to the sizes, shapes, and connection relationships of the components for positioning and installing the components.

[0043] The flip cover 10 is used to isolate the components to be protected from the external environment and prevent the components from being exposed. The position of the flip cover 10 on the electric meter body 20 corresponds to the components to be protected. For example, if the flip cover 10 is to protect the wiring part, the position of the flip cover 10 is set corresponding to the wiring part so that the wiring part is closed after the flip cover 10 is closed. If the flip cover 10 is to protect the display module, the position of the flip cover 10 is set corresponding to the display module so that the display module is closed after the flip cover 10 is closed.

[0044] The flip cover 10 is flippably arranged on the meter body 20. Specifically, it can be arranged that the first side of the flip cover 10 is rotatably connected to the meter body 20, so that the rotation axis of the flip cover 10 is located on the first side of the flip cover 10, and the first side refers to the side close to the first edge 131 of the flip cover 10. The flip cover 10 can also be arranged that the middle section of the flip cover 10 is rotatably connected to the meter body 20, such as making the rotation shaft 31 located on the central axis of the flip cover 10, so that the flip cover 10 forms a lever structure with the rotation axis as the fulcrum, and when one side located on both sides of the flip cover 10 is tilted up, the other side falls down synchronously.

[0045] The flip cover 10 can be connected to the meter body 20 via a single shaft 31 or via multiple shafts 31. The shaft 31 can be a separate component or can be fixedly set on the flip cover 10 or the meter body 20. When the shaft 31 is a separate component, both the flip cover 10 and the meter body 20 are provided with shaft holes 32 corresponding to the shaft 31. When the shaft 31 is fixedly set on the meter body 20, the flip cover 10 is provided with shaft holes 32 corresponding to the shaft 31. When the shaft 31 is fixedly set on the flip cover 10, the meter body 20 is provided with shaft holes 32 corresponding to the shaft 31, as shown in FIG. Figure 3 and Figure 4 As shown, Figure 3 This is a schematic diagram of the structure of a flip cover involved in an embodiment of the present application. Figure 4 This is a schematic diagram of the local structure of an electric meter body involved in an embodiment of the present application.

[0046] like Figure 1 and Figure 2 As shown, the flip cover 10 is provided with a first engaging portion 11. The meter body 20 is provided with a second engaging portion 21 corresponding to the first engaging portion 11, and the first engaging portion 11 can form an interference fit with the second engaging portion 21 as the flip cover 10 is buckled, so as to keep the flip cover 10 in the buckled position.

[0047] The first engaging portion 11 and the second engaging portion 21 are structures that match each other to form an interference fit, and both can be set to one or more. The interference fit in this embodiment refers to the relative position relationship between the first engaging portion 11 and the second engaging portion 21, which forms an interaction force that blocks each other when the two are in contact, thereby forming a tight connection, which is similar to and includes the interference fit of a hole and a shaft.

[0048] The first engaging portion 11 is disposed on the flip cover 10 and moves synchronously with the movement of the flip cover 10. When the flip cover 10 is buckled under the action of an external force, the first engaging portion 11 continuously approaches the second engaging portion 21 and forms an interference fit with the second engaging portion 21 when the flip cover 10 reaches the buckled position. The buckled position is the final resting position of the flip cover 10 to protect the components after buckling.

[0049] When the user wants to close the flip cover 10, the user only needs to perform a closing action and apply sufficient closing force to the flip cover 10, so that the flip cover 10 can reach the closing position and complete the closing of the flip cover 10. Since the first engaging portion 11 and the second engaging portion 21 form an interference fit when the flip cover 10 reaches the closing position, if the external force received by the first engaging portion 11 does not reach the release threshold of the interference fit, the flip cover 10 will still remain in the closed position, thus realizing the locking of the flip cover 10 and preventing the flip cover 10 from being accidentally opened by being accidentally touched by other objects, thereby protecting the components to be protected.

[0050] When the user wants to open the flip cover 10, the user only needs to perform an opening action and apply sufficient opening force to the flip cover 10, that is, make the force to open the flip cover 10 greater than the release threshold of the interference fit, so as to release the interference fit between the first engaging portion 11 and the second engaging portion 21, unlock the flip cover 10, and then easily open the flip cover 10.

[0051] In this embodiment, there are many specific structural forms of the first engaging portion 11 and the second engaging portion 21. For example, it can be set as a shaft-hole type fitting structure, or a fitting structure of a clamping block and a clamping groove, or other forms of structures that can perform interference fit. The following gives an example for illustration.

[0052] The first exemplary implementation manner of the first engaging portion 11 and the second engaging portion 21 can be as Figure 3 、 Figure 4 、 Figure 5 and Figure 6 shown. Figure 5 FIG. 20 is a partial front view of the flip cover of the electric meter involved in the embodiment of the present application when it is opened. Figure 6 FIG. 22 is a partial front view of the flip cover of the electric meter involved in the embodiment of the present application when it is closed. Wherein, the first engaging portion 11 is a protruding portion 111, and the second engaging portion 21 is a groove 211 corresponding to the protruding portion 111. The protruding portion 111 can extend into the groove 211 along with the closing of the flip cover 10 and form an interference fit with the inner wall of the groove 211.

[0053] The protruding portion 111 is a component protruding from the cover plate 12 of the flip cover 10, and it can specifically be a convex platform, a convex column or other protruding structures. The groove 211 is a structure provided on the electric meter body 20 that can catch the protruding portion 111, and it is located on the moving path of the protruding portion 111, so that the protruding portion 111 just extends into the groove 211 and forms an interference fit with the inner wall of the groove 211 when moving along with the flip cover 10.

[0054] In order to increase the release threshold of the interference fit, the protruding portion 111 can be further configured. For example, the interference amount between the protruding portion 111 and the groove 211 can be increased. Alternatively, a structure such as an insert 112 can be provided on the protruding portion 111 to increase the resistance when the interference fit is released.

[0055] Exemplarily, in a specific implementation manner of providing the insert 112, the insert 112 is provided on the protruding portion 111, and an insertion groove 212 corresponding to the insert 112 is provided on the inner wall of the groove 211. The insert 112 can slide into the insertion groove 212 along the inner wall of the groove 211 as the flip cover 10 is fastened, and the insert 112 can slide out of the insertion groove 212 as the flip cover 10 is opened.

[0056] The insert 112 can be a structure integral with the protruding portion 111 and protruding from the protruding portion 111, or can be another part added to the protruding portion 111 by means of threaded connection, snap connection, bonding, etc. Moreover, the protruding size of the insert 112 is set within a smaller preset size range to prevent the insert 112 from being too large and affecting the docking of the protruding portion 111 and the groove 211.

[0057] The outer shape of the insert 112 can be specifically set as an arc, a rectangle, etc. Similarly, the groove shape of the insertion groove 212 can also be set as an arc, a rectangle, etc., which is not limited herein. In an alternative implementation manner, the outer surface of the insert 112 is an arc, and / or the groove surface of the insertion groove 212 is an arc. That is to say, at least one of the insert 112 and the insertion groove 212 is set as an arc, so that when the insert 112 moves along with the protruding portion 111, it can smoothly extend into the insertion groove 212 or slide out of the insertion groove 212 under the guiding action of the arc-shaped outer surface.

[0058] A second exemplary implementation manner of the first engaging portion 11 and the second engaging portion 21 can be that the first engaging portion 11 is a groove, and the second engaging portion 21 is a protruding portion corresponding to the groove. The protruding portion can extend into the groove when the flip cover 10 is fastened and form an interference fit with the inner wall of the groove.

[0059] In this exemplary implementation manner, a groove is provided on the first engaging portion 11, and a protruding portion is provided on the second engaging portion 21. Specifically, the positions of the groove 211 and the protruding portion 111 in the first exemplary implementation manner of the first engaging portion 11 and the second engaging portion 21 are swapped. Its specific structure is analogous to the relevant content of an exemplary implementation manner, and will not be elaborated herein.

[0060] In this embodiment, the mutual cooperation between the first engaging portion 11 and the second engaging portion 21 enables the flip cover 10 to be automatically locked in the closed position when the user performs a closing action, and can also be automatically unlocked when the user performs an opening action. On this basis, this embodiment further provides a structure that enables the flip cover 10 to remain in the open state after being opened, based on the first engaging portion 11 and the second engaging portion 21.

[0061] A feasible structure for maintaining the open state can be as Figure 3 、 Figure 4 and Figure 7 and Figure 8 shown. Figure 7 FIG. is a partial cross-sectional view when the flip cover of the electric meter involved in the embodiment of the present application is closed. Figure 8 FIG. is a partial cross-sectional view when the flip cover of the electric meter provided by the embodiment of the present application is opened. Among them, the first side of the flip cover 10 is rotatably connected to the electric meter body 20. A first resisting portion 13 is provided on the first side of the flip cover 10, and a second resisting portion 22 corresponding to the first resisting portion 13 is provided on the electric meter body 20. The first resisting portion 13 can abut against the second resisting portion 22 as the flip cover 10 is opened to block the closing of the flip cover 10.

[0062] The first resisting portion 13 and the second resisting portion 22 are mutually cooperating structures. When the two abut against each other, they can block the closing of the flip cover 10, and both of them can be set to one or more. In a specific implementation manner, the first resisting portion 13 and the second resisting portion 22 can be an embedded abutting structure or a non-embedded abutting structure. Hereinafter, the structures of the first resisting portion 13 and the second resisting portion 22 will be exemplarily described with an embedded abutting structure.

[0063] A feasible implementation manner is as Figure 7 and Figure 8 shown. The first resisting portion 13 is the first edge 131 on the first side of the flip cover 10, and the second resisting portion 22 is the abutting groove 221 corresponding to the first edge 131. The first edge 131 can be inserted into the abutting groove 221 as the flip cover 10 is opened to block the closing of the flip cover 10 through the groove wall of the abutting groove 221.

[0064] Among them, the first edge 131 refers to the edge portion at the end of the first side of the flip cover 10. The first edge 131 rotates around the rotation axis of the flip cover 10 when the flip cover 10 is flipped. The abutting groove 221 is a groove structure that can catch the first edge 131. Its shape and size correspond to the shape and size of the first edge 131, and the abutting groove 221 is located on the rotation path of the first edge 131 so that the first edge 131 can be just inserted into the abutting groove 221 when it rotates.

[0065] The outer surface of the first edge 131 can be set to an angular shape or an arc shape without corners. Similarly, the inner surface of the abutting groove 221 can be set to an angular shape or an arc shape without corners. In an alternative embodiment, the outer surface of the first edge 131 and the surface of the abutting groove 221 are both set to an arc shape to make the process of the first edge 131 being inserted into or removed from the abutting groove 221 smoother.

[0066] It should be clear that the first abutting portion 13 only abuts against the second abutting portion 22 after the flip cover 10 is flipped to a preset angle, and the abutment between the first abutting portion 13 and the second abutting portion 22 will not be released when the external force is small. It allows the first abutting portion 13 and / or the second abutting portion 22 to achieve abutment or release of abutment through slight elastic deformation during the abutment process to ensure the reliability of the abutment, thereby ensuring the effect of blocking the flip cover 10 from closing.

[0067] For example, when the first abutting portion 13 is the first edge 131 on the first side of the flip cover 10 and the second abutting portion 22 is the abutting groove 221 corresponding to the first edge 131, the first abutting portion 13 rotates with the flip cover 10. When the first abutting portion 13 approaches the abutting groove 221, it can undergo partial deformation and smoothly slide into the abutting groove 221, and then recover the deformation after entering the abutting groove 221, so that the first edge 131 is reliably inserted into the abutting groove 221.

[0068] Furthermore, in order to make the process of the first edge 131 entering the abutting groove 221 smoother, a guiding portion 23 can be provided corresponding to the first abutting portion 13 and / or the second abutting portion 22. For example, when the first abutting portion 13 is the first edge 131 on the first side of the flip cover 10 and the second abutting portion 22 is the abutting groove 221 corresponding to the first edge 131, a setting method of a guiding portion 23 can be specifically as Figure 7 shown, a guiding portion 23 is provided at the opening of the abutting groove 221, and the guiding portion 23 is located on the moving path of the first edge 131, so that the first edge 131 slides into the abutting groove 221 under the guiding action of the guiding portion 23.

[0069] When the flip cover 10 is opened, the first edge 131 rotates with the flip cover 10 and slides against the surface of the guiding portion 23 during rotation. The first edge 131 undergoes elastic deformation under the action of the guiding portion 23. After the first edge 131 passes through the guiding portion 23, it slides to the abutting groove 221. At this time, it no longer receives the action of the guiding portion 23 and recovers the deformation, and the first edge 131 is successfully inserted into the abutting groove 221.

[0070] There are many forms of setting the guiding part 23, which can be structures such as inclined surfaces and arc surfaces arranged at the opening of the abutting groove 221, or can be arranged as guiding rib plates, guiding ribs and other structures, and are not limited here. Of course, the guiding part 23 can be arranged on the cover plate 12 or on the electricity meter body 20, and is not limited here.

[0071] In this embodiment, the first edge 131 that cooperates with the abutting groove 221 is the side edge of the first side of the flip cover 10, which has the advantages of simple structure and convenient processing of the flip cover 10. Of course, in other feasible embodiments, the first edge 131 can be replaced with a convex platform, a clamping block and other protruding structures arranged on the first side of the flip cover 10, that is, the first blocking part 13 is arranged as a protruding structure. The protruding structure can be clamped into the abutting groove 221 along with the flipping of the flip cover 10 to realize the blocking of the buckling of the flip cover 10. The protruding structure is a structure protruding from the cover plate 12 and has the same function as the first edge 131. Moreover, the appearance of the protruding structure can be set to a shape with edges and corners or an arc without edges and corners, and a guiding structure can also be further set, which is analogous to the relevant content of the above first edge 131 and will not be elaborated here.

[0072] Of course, the positions of the protruding structure and the abutting groove 221 can also be interchanged, that is, the first blocking part 13 is an abutting groove arranged on the first side of the flip cover 10, and the second blocking part 22 is arranged as a protruding structure corresponding to the abutting groove. The abutting groove can catch the protruding structure along with the opening of the flip cover 10 to block the buckling of the flip cover 10 through the protruding structure. The abutting groove and the protruding structure are analogous to the foregoing relevant content and will not be elaborated here.

[0073] In addition, in order to prevent unauthorized personnel from opening the electricity meter for improper operations, on the basis of the above various embodiments, lead seals can be further arranged on the electricity meter flip cover 10 and the electricity meter body 20 to seal the flip cover 10. The specific implementation method can be as Figure 2 shown, a first lead seal 14 is arranged on the flip cover 10, a second lead seal 24 is arranged on the electricity meter body 20, and the lead seal wire passes through the first lead seal 14 and the second lead seal 24 in sequence to seal the flip cover 10 and the electricity meter body 20.

[0074] The first lead seal 14 can be one or more, and the second lead seal 24 can also be one or more. The opening shapes of the first lead seal 14 and the second lead seal 24 can be rectangular, circular, oval, etc., and the opening shapes of the first lead seal 14 and the second lead seal 24 can be the same or different, and are not limited here.

[0075] In summary, in the electricity meter described above, a first engaging portion is provided on the flip cover, and a second engaging portion corresponding to the first engaging portion is provided on the electricity meter body, and the first engaging portion can form an interference fit with the second engaging portion as the flip cover is closed. When the user closes the flip cover, only a single closing action needs to be performed on the flip cover to make the first engaging portion of the flip cover and the second engaging portion form an interference fit, so that the flip cover is locked to form protection. When the user opens the flip cover, only a single opening action needs to be performed on the flip cover to release the interference fit between the first engaging portion and the second engaging portion, so that the locking of the flip cover is released and the flip cover is opened. Therefore, in this type of electricity meter, the locking and unlocking of the flip cover can be automatically completed when the flip cover is closed and opened, without specific locking and unlocking actions, the operation is more convenient, and the convenience is higher.
