Description

Technical Field

[0001] This utility model relates to the field of electricity meter technology, and in particular to a flip-type electricity meter. Background Technology

[0002] Existing rail-mounted energy meters have wiring requirements for functional terminals such as communication and pulse. In order to protect the functional terminals, rail-mounted energy meters are generally equipped with a flip cover. When the flip cover is closed, it can cover the functional terminals to protect them. When wiring is required, the flip cover can be opened.

[0003] However, the existing flip cover cannot be fixed in the open position after being opened, requiring staff to hold the flip cover while wiring, which makes wiring difficult. Furthermore, there is no corresponding limiting structure when the flip cover is closed, making it easy for the flip cover to be accidentally opened or for problems such as the flip cover tilting up.

[0004] Therefore, there is an urgent need to develop a flip-type electricity meter to solve the above-mentioned technical problems. Utility Model Content

[0005] This utility model provides a flip-type energy meter, which can remain in the open position after the flip is opened, making it convenient for wiring; and can remain in the closed position after the flip is closed, which can prevent the flip from being accidentally opened or lifted up. Moreover, the flip has a clear tactile indication when it is closed, and the closure reliability is also high.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] Flip-type electricity meters include:

[0008] The housing has a wiring portion and an opening limiting portion and a closing limiting portion near the wiring portion. The closing limiting portion includes a first limiting protrusion and a limiting groove disposed on the first limiting protrusion.

[0009] A flip cover is rotatably connected to the housing and has an open position that exposes the wiring portion and a closed position that covers the wiring portion. The flip cover is provided with an opening limiting engagement portion and a closing limiting engagement portion. The opening limiting engagement portion is used to cooperate with the opening limiting portion to keep the flip cover in the open position. During the process of the flip cover rotating from the open position to the closed position, the closing limiting engagement portion can press against the first limiting protrusion and finally be engaged in the limiting groove.

[0010] Optionally, the opposite side walls of the flip cover are rotatably connected to the opposite side sides of the wiring part, the side of the wiring part is provided with the opening limiting part and the closing limiting part, and the side wall of the flip cover is provided with the opening limiting mating part and the closing limiting mating part.

[0011] Optionally, the opening limiting part and the closing limiting part are provided on both opposite sides of the wiring part, and the opening limiting mating part and the closing limiting mating part are provided on both opposite side walls of the flip cover.

[0012] Optionally, the closing limiting fitting part has a hemispherical structure, and the limiting groove is a hemispherical groove that mates with the hemispherical structure.

[0013] Optionally, the first limiting protrusion is further provided with a first arc-shaped guide surface, and the closing limiting mating part presses against the first limiting protrusion under the guidance of the first arc-shaped guide surface.

[0014] Optionally, the opening limiting fitting part includes a second limiting protrusion, the side of which has a smoothly connected arc-shaped transition section and a limiting section, and the opening limiting part is a limiting rib; during the process of the flip cover rotating from the closed position to the open position, the arc-shaped transition section is interference-fitted with the side wall of the limiting rib, and when the flip cover is in the open position, the limiting section abuts against the top wall of the limiting rib.

[0015] Optionally, the sidewalls and topwalls of the limiting rib are connected by a second arc-shaped guide surface.

[0016] Optionally, when the flip cover is in the open position, the opening angle of the flip cover is 80°-98°.

[0017] Optionally, the wiring portion has oppositely arranged connecting holes on opposite sides, and the flip cover has oppositely arranged rotating shafts on opposite side walls, the rotating shafts being rotatably connected to the corresponding connecting holes.

[0018] Optionally, the housing is further provided with a first threading hole, and the flip cover is provided with a second threading hole corresponding to the first threading hole. When the flip cover is in the closed position, the first threading hole and the second threading hole form an arc-shaped threading channel, which is used for threading lead sealing wire.

[0019] The beneficial effects of this utility model are:

[0020] This utility model provides a flip-type energy meter, including a housing and a flip cover. The flip cover has an open position that exposes the wiring portion and a closed position that covers the wiring portion. When the flip cover is rotated to the open position, the opening limiting part on the flip cover engages with the opening limiting part on the housing, keeping the flip cover in the open position for easy wiring. During the process of rotating the flip cover from the open position to the closed position after wiring is completed, the closing limiting part on the flip cover first presses against the first limiting protrusion of the closing limiting part. At this time, resistance to rotating the flip cover can be felt. As the flip cover is rotated further, the closing limiting part slides on the first limiting protrusion and finally engages in the limiting groove on the first limiting protrusion, keeping the flip cover in the closed position, preventing the flip cover from being accidentally opened or lifted, and improving the reliability of the flip cover closure.

[0021] Both the first limiting protrusion and the limiting groove of the closing limiting part can restrict the rotation of the flip cover through the closing limiting mating part, achieving double locking of the flip cover closure and further improving the reliability of the flip cover closure. In addition, the closing limiting mating part can produce a clear tactile indication when it is engaged with the limiting groove, reducing the difficulty of operation. Attached Figure Description

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0035] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0037] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0038] This embodiment provides a flip-type energy meter, which can remain in the open position after the flip is opened, making it convenient for wiring; and can remain in the closed position after the flip is closed, which can prevent the flip from being accidentally opened or tilted up, and the flip has a clear tactile indication when it is closed, and the closure reliability is also high.

[0039] Specifically, such as Figures 1-4 As shown, the flip-type energy meter includes a housing 100 and a flip cover 200. The housing 100 has a wiring portion 110, an opening limiting portion 120, and a closing limiting portion 130 near the wiring portion 110. The closing limiting portion 130 includes a first limiting protrusion 131 and a limiting groove 132 provided on the first limiting protrusion 131. The flip cover 200 is rotatably connected to the housing 100 and has an open position exposing the wiring portion 110 and a closed position covering the wiring portion 110. The flip cover 200 has an opening limiting engagement portion 210 and a closing limiting engagement portion 220.

[0040] When the flip-type energy meter needs to be wired, the flip cover 200 is rotated to move it to the open position. At this time, the opening limit fitting part 210 on the flip cover 200 cooperates with the opening limit part 120 on the housing 100 to keep the flip cover 200 in the open position, so that the staff can perform wiring.

[0041] After the wiring is completed, during the process of rotating the flip cover 200 from the open position to the closed position, the closing limiting engagement part 220 on the flip cover 200 will first press against the first limiting protrusion 131 of the closing limiting part 130. At this time, the resistance of rotating the flip cover 200 can be felt. As the flip cover 200 is rotated further, the closing limiting engagement part 220 will slide on the first limiting protrusion 131 and finally be engaged in the limiting groove 132 on the first limiting protrusion 131, so that the flip cover 200 is kept in the closed position, preventing the flip cover 200 from being accidentally opened or tilted up, and improving the reliability of the flip cover 200 closing.

[0042] Both the first limiting protrusion 131 and the limiting groove 132 of the closing limiting part 130 can restrict the rotation of the flip cover 200 through the closing limiting engagement part 220, achieving double locking of the flip cover 200 and further improving the reliability of the flip cover 200 closing. Furthermore, the closing limiting engagement part 220 provides a clear tactile feedback when it engages with the limiting groove 132, reducing the difficulty of operation.

[0043] Optionally, when the flip cover 200 is in the open position, the opening angle of the flip cover 200 is 80°-98°. This angle can prevent the flip cover 200 from obstructing the wiring terminals on the wiring section 110.

[0044] Optionally, in one possible embodiment, the flip-type energy meter has a wiring portion 110, and therefore, a corresponding flip cover 200 is provided. In another possible embodiment, the flip-type energy meter may also have two wiring portions 110, and therefore, two corresponding flip covers 200 are provided.

[0045] Further, see also Figures 1-3 The opposite side walls of the flip cover 200 are rotatably connected to the opposite side walls of the wiring portion 110. The side of the wiring portion 110 is provided with an opening limit portion 120 and a closing limit portion 130. The side wall of the flip cover 200 is provided with an opening limit mating portion 210 and a closing limit mating portion 220. This arrangement ensures that the mating error between the opening limit mating portion 210 on the flip cover 200 and the opening limit portion 120 on the housing 100, and between the closing limit mating portion 220 on the flip cover 200 and the closing limit portion 130 on the housing 100, is only related to its own machining error, and is not affected by the assembly error of the rotatable connection between the flip cover 200 and the housing 100, thus reducing the machining difficulty of this flip-type energy meter. Furthermore, when the flip cover 200 is in the closed position, the opening limit fitting part 210 and the closing limit fitting part 220 on the flip cover 200, as well as the opening limit part 120 and the closing limit part 130 on the housing 100, can be hidden, which improves the aesthetics of the flip-type energy meter.

[0046] Optionally, in this embodiment, an opening limiting part 120 and a closing limiting part 130 are provided on opposite sides of the wiring portion 110. An opening limiting engagement part 210 and a closing limiting engagement part 220 are provided on opposite sides of the flip cover 200. This arrangement improves the reliability of the flip cover 200 in maintaining the open and closed positions.

[0047] Optionally, the opening limit part 120 and the closing limit part 130 can be integrated with the wiring part 110 to facilitate processing.

[0048] Further, see also Figure 3 and Figure 4 In this embodiment, the wiring portion 110 has oppositely arranged connecting holes 111 on its opposite sides, and the flip cover 200 has oppositely arranged rotating shafts 230 on its opposite side walls. The rotating shafts 230 are rotatably connected to their corresponding connecting holes 111. The rotating connection between the flip cover 200 and the housing 100 is achieved through the cooperation of the rotating shafts 230 and the connecting holes 111. The structure is simple, easy to assemble, and has good rotational smoothness.

[0049] Further, see also Figure 3 The first limiting protrusion 131 is also provided with a first arc-shaped guide surface 1311. The closing limiting mating part 220 presses against the first limiting protrusion 131 under the guidance of the first arc-shaped guide surface 1311. By providing the first arc-shaped guide surface 1311, the mating between the closing limiting mating part 220 and the first limiting protrusion 131 can be guided, improving the smoothness of the closing of the flip cover 200.

[0050] Optionally, such as Figures 3-5 As shown, in this embodiment, the closing limiting fitting part 220 has a hemispherical structure, and the limiting groove 132 is a hemispherical groove that mates with the hemispherical structure. The hemispherical structure and the first limiting protrusion 131 are in point contact, resulting in low friction, which helps protect the hemispherical structure. Furthermore, the hemispherical structure and the hemispherical groove are easy to engage, reducing the difficulty of closing the flip cover 200.

[0051] Furthermore, such as Figure 3 , Figure 6 and Figure 7As shown, the opening limiting fitting part 210 includes a second limiting protrusion 211. The side of the second limiting protrusion 211 has a smoothly connected arc-shaped transition section 212 and a limiting section 213. The opening limiting part 120 is a limiting rib. During the process of the flip cover 200 rotating from the closed position to the open position, the arc-shaped transition section 212 is press-fitted with the side wall of the limiting rib. When the flip cover 200 is in the open position, the limiting section 213 abuts against the top wall of the limiting rib. With this configuration, both the arc-shaped transition section 212 and the limiting section 213 can restrict the rotation of the flip cover 200 through the limiting rib, achieving double locking of the flip cover 200 opening. This makes it difficult for the flip cover 200 to close even if accidentally touched, improving the reliability of the flip cover 200 opening.

[0052] Optionally, see [link to relevant documentation] Figure 3 and Figure 6 The side and top walls of the limiting rib are connected by the second arc-shaped guide surface 121. This design allows the flip cover 200 to rotate more smoothly and stably.

[0053] Optionally, see [link to relevant documentation] Figure 4 In this embodiment, the pivot 230 is disposed on the second limiting protrusion 211. This arrangement helps to improve the structural strength of the flip cover 200 at the pivot 230, thereby improving the reliability of the rotatable connection between the flip cover 200 and the housing 100.

[0054] Currently, traditional flip-type energy meters typically have lead-sealed openings on the flip cover and casing for installing lead seals (lead seal wire and lead seal), ensuring the flip cover is firmly closed and preventing unauthorized alteration of the wiring after completion. However, currently, it is difficult to thread the lead seal wire through the lead seal wire hole in the flip cover and casing, affecting the installation efficiency of operators.

[0055] See also Figure 2 , Figure 4 and Figure 6 To address the aforementioned technical issues, the flip-type energy meter provided in this embodiment further includes a first wire-passing hole 140 on the housing 100 and a second wire-passing hole 240 corresponding to the first wire-passing hole 140 on the flip cover 200. When the flip cover 200 is in the closed position, the first wire-passing hole 140 and the second wire-passing hole 240 form an arc-shaped wire-passing channel, which is used for the lead-sealing wire 300 to pass through. By setting the arc-shaped wire-passing channel, the insertion of the lead-sealing wire 300 can be guided, reducing the assembly difficulty of the lead-sealing wire 300 and thus improving the installation efficiency of the operator.

[0056] Optionally, in this embodiment, a first threading hole 140 is provided on each of the opposite sides of the housing 100, and a second threading hole 240 is provided for each first threading hole 140. By providing two pairs of first threading holes 140 and second threading holes 240 for lead sealing, the locking reliability of the flip cover 200 is improved.

[0057] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
