Technical Field

[0001] This utility model relates to the field of electricity meters, and in particular to an electricity meter. Background Technology

[0002] Currently, wiring and installing smart meters is very time-consuming and requires professional personnel and tools. For this scenario, there are specially designed spring terminal blocks with built-in operating handles that can achieve tool-free operation. However, the operating handle is directly connected to the elastic device. When the elastic device rebounds, the hand will be quickly rebounded due to the force. If the fingers are in the path of its movement, there is a safety hazard of being injured. Utility Model Content

[0003] One objective of this invention is to address the shortcomings of existing technologies by proposing a structural design for an anti-slapping handle. This design involves disassembling the individual handles, allowing them to retain their normal prying function, and ensuring that the elastic force of the elastic device does not directly act on the operating handle when the handle is reset, thus solving the problem of hand slapping.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] An electricity meter includes: a housing with an internal mounting space and a wire passage hole; a movable component located within the housing, the movable component including a movable seat and an elastic member disposed within the movable seat, the movable seat being movably disposed on one side of the wire passage hole; a stop member rotatably disposed above the movable seat; an operating handle rotatably connected to the stop member via a rotating shaft, the operating handle and the stop member having a first abutment position and a second abutment position, the operating handle being freely rotatable relative to the stop member between the first abutment position and the second abutment position; the rotation position of the operating handle includes a first position, a second position, and a third position, the third position being located between the first position and the second position; the operating handle abuts against the stop member. Holding at the first abutment position, the operating handle drives the abutment member to rotate in the forward direction around the rotation axis, causing the operating handle to rotate from the first position to the second position. The abutment member presses down on the movable seat, causing the movable seat to move downward. The elastic member undergoes elastic deformation, and the cable passage hole opens to allow the cable to pass through the installation space. The operating handle rotates in the opposite direction relative to the abutment member, and the operating handle and the abutment member abut against each other at the second abutment position. The operating handle is located at the third position. The operating handle and the abutment member abut against each other at the second abutment position. The reverse rotation of the operating handle drives the abutment member to rotate in the opposite direction to disengage from the movable seat. The elastic member rebounds, the movable seat moves upward, the abutment member rotates in the opposite direction, and abuts against the operating handle at the first abutment position. The movable seat presses against the cable.

[0006] In an exemplary embodiment, the end of the abutment near the operating handle is provided with a first abutting portion, and the end wall of the operating handle near the abutment is provided with a first abutting wall; when the operating handle and the abutment are abutted at the first abutting position, the first abutting portion abuts against the first abutting wall.

[0007] In an exemplary embodiment, the end of the operating handle near the abutment is provided with a second abutting portion, and the end wall of the abutment near the operating handle is provided with a second abutting wall; when the operating handle and the abutment are abutted at the second abutting position, the second abutting portion abuts against the second abutting wall.

[0008] In an exemplary embodiment, the operating handle has a third abutting wall on its end wall near the abutting member, the third abutting wall being disposed between the second abutting portion and the first abutting wall; the abutting member has a fourth abutting wall on its end wall near the operating handle; the fourth abutting wall being disposed between the first abutting portion and the second abutting wall; when the operating handle abuts against the abutting member at the first abutting position, the third abutting wall abuts against the fourth abutting wall.

[0009] In one exemplary embodiment, the first abutment wall and the second abutment wall are concentrically arranged with the rotation axis.

[0010] In one exemplary embodiment, the operating handle includes a driving part and a connecting part; the abutting member includes an abutting part and a clamping part, the clamping part having a clamping space therein; the connecting part extends into the clamping space, and the connecting part and the clamping part are rotatably connected by a rotating shaft.

[0011] In an exemplary embodiment, the bottom of the movable seat is provided with a blocking plate, which is arranged directly opposite the wire passage hole; when the operating handle is in the first position, the blocking plate blocks the wire passage hole; when the operating handle is in the second position, the blocking plate opens the wire passage hole.

[0012] In an exemplary embodiment, a fixing member is provided within the installation space, and the fixing member is fixed within the installation space; one end of the elastic member abuts against the fixing member, and the other end of the elastic member abuts against the movable seat, and the extension direction of the elastic member is the same as the movement direction of the movable seat.

[0013] In one exemplary embodiment, the top of the housing has a rotating opening, and the operating handle is rotatably disposed within the rotating opening; when the operating handle is in a first position, the operating handle abuts against one end wall of the rotating opening; when the operating handle is in a second position, the operating handle abuts against the other end wall of the rotating opening.

[0014] In one exemplary embodiment, the housing includes a body and a rear cover disposed at the rear end of the body, the mounting space being formed between the body and the rear cover; the rotation opening is located at the top of the body.

[0015] As can be seen from the above technical solution, this utility model has at least the following advantages and positive effects:

[0016] This utility model provides an electricity meter that utilizes an operating handle that is rotatably positioned between a first abutment position and a second abutment position relative to abutment members. When rotating between the first and second abutment positions, no force is transmitted between the operating handle and the abutment members. This allows the operating handle to reset a certain distance before the elastic member rebounds. Consequently, when the elastic member rebounds, its force is first transmitted to the abutment members, which then rotate a certain distance before driving the operating handle to reset. Therefore, this application reduces the reset path of the operating handle when the elastic member rebounds, thereby reducing the range of motion of the elastic member during reset and reducing the risk of injury when the operating handle rebounds rapidly.

[0025] Currently, wiring and installing smart meters is very time-consuming and requires professional personnel and tools. For this scenario, there are specially designed spring terminal blocks with built-in operating handles that can achieve tool-free operation. However, the operating handle is directly connected to the elastic device. When the elastic device rebounds, the hand will be quickly rebounded due to the force. If the fingers are in the path of its movement, there is a safety hazard of being injured.

[0026] Figure 1 This is a cross-sectional view of an embodiment of the electricity meter provided by this utility model. Figure 2 yes Figure 1 A diagram of another state. Figure 3 yes Figure 1 A diagram illustrating yet another state. Figure 4 This is a schematic diagram of cable 6 installed in the electricity meter.

[0027] Please see Figures 1 to 4 As shown, the electricity meter includes a housing 1, a moving component 2, a contact part 3, and an operating handle 4.

[0028] In some embodiments, the housing 1 can serve as the outer casing of an electricity meter. The interior of the housing 1 is hollow. The interior of the housing 1 is provided with a mounting space 11, which can be used to accommodate devices.

[0029] In some embodiments, a wire-passing hole 12 may be provided on the side wall of the housing 1. The wire-passing hole 12 is used for inserting the cable 6.

[0030] In some embodiments, a copper sheet 13 may be provided inside the housing 1. The copper sheet 13 can be used to electrically connect with the connection terminals inside the electricity meter.

[0031] In some embodiments, the housing 1 may include a body 14 and a rear cover 15 disposed at the rear end of the body 14, and the mounting space 11 may be formed between the body 14 and the rear cover 15.

[0032] In some embodiments, the copper sheet 13 can be positioned directly opposite the wire hole 12, so that when the cable 6 outside the energy meter is inserted through the wire hole 12, the cable 6 can be electrically connected to the copper sheet 13, thereby realizing the connection between the cable 6 and the internal connection terminal of the energy meter.

[0033] In some embodiments, the movable component 2 is disposed within the housing 1. The movable component 2 may include a movable seat 21 and an elastic member 22, wherein the elastic member 22 is disposed inside the movable seat 21. The movable seat 21 is movably disposed on one side of the wire hole 12.

[0034] In some embodiments, the wire hole 12 may be located on one side of the movable base 21. The movable base 21 may cover one side of the wire hole 12, thereby providing dust protection and protection against electric shock.

[0035] In some embodiments, the elastic element 22 can undergo elastic deformation. When the movable seat 21 covers the cable hole 12, the cable 6 outside the housing 1 cannot extend into the installation space 11, at which time the elastic element 22 is in a relaxed state.

[0036] In some embodiments, the electricity meter includes a handle assembly and a rotating shaft 5. The handle assembly is rotatably mounted on the housing 1 via the rotating shaft 5. One end of the handle assembly extends into the mounting space 11, and the other end extends out of the housing 1. The end of the handle assembly extending into the mounting space 11 can be positioned above the movable seat 21. The user can drive the handle assembly to rotate forward, causing the handle assembly to move the movable seat 21 downward and causing the elastic element 22 to elastically deform, thereby opening the wire hole 12 in the movable seat 21 to allow the cable 6 to pass through the mounting space 11 and achieve electrical connection with the terminal block.

[0037] In some embodiments, the user can drive the handle assembly to rotate in the opposite direction, thereby causing the handle assembly to disengage from the movable seat 21, causing the elastic element 22 to rebound and the movable seat 21 to move upward. If the cable 6 passes through the cable hole 12 and enters the installation space 11 at this time, the movable seat 21 can hold the cable 6 to improve the stability of the cable 6 connection; if no cable 6 passes through the cable hole 12 at this time, the movable seat 21 can move upward and reset.

[0038] In some embodiments, the handle assembly includes an abutment 3 and an operating handle 4. The abutment 3 is rotatably disposed above the movable base 21. The operating handle 4 is rotatably connected to the abutment 3 via a rotating shaft 5. The operating handle 4 can extend out of the housing 1. The user can drive the operating handle 4 to rotate the abutment 3, thereby causing the abutment 3 to rotate.

[0039] In some embodiments, the rotation position of the operating handle 4 may include a first position and a second position.

[0040] When the user rotates the operating handle 4 in the forward direction, the operating handle 4 can drive the abutment 3 to rotate in the forward direction around the rotating shaft 5, so that the operating handle 4 can rotate from the first position to the second position, and drive the abutment 3 to press down the movable seat 21, so that the movable seat 21 moves down, the elastic member 22 undergoes elastic deformation, and the wire hole 12 opens to allow the cable 6 to pass through the installation space 11, so as to realize the electrical connection with the terminal block.

[0041] When the user rotates the operating handle 4 in the opposite direction, the operating handle 4 can drive the abutment 3 to rotate in the opposite direction around the rotating shaft 5, so that the operating handle 4 can rotate back from the second position to the first position, and the abutment 3 disengages from the movable seat 21, causing the elastic element 22 to rebound, the movable seat 21 to move upward, and the movable seat 21 presses the cable 6, improving the stability of the cable 6 installation.

[0042] In some embodiments, the operating handle 4 may have a third position. The third position may be located between the first position and the second position. When the operating handle 4 is in the second position, the operating handle 4 can rotate in the opposite direction relative to the abutment 3, so that the operating handle 4 can rotate from the second position back to the third position. During this process, no force is transmitted between the operating handle 4 and the abutment 3. At this time, the abutment 3 and the movable seat 21 are still in the state of the second position, that is, the abutment 3 abuts against the top surface of the movable seat 21, the elastic member 22 is in a compressed state, and the movable seat 21 opens the wire hole 12 to allow the cable 6 to pass through.

[0043] In some embodiments, when the operating handle 4 is in the third position, the user can continue to push the operating handle 4 to rotate in the opposite direction. At this time, the operating handle 4 can drive the abutment 3 to rotate in the opposite direction, so that the abutment 3 disengages from the movable seat 21, causing the elastic member 22 to rebound, the movable seat 21 to move upward, and press the cable 6.

[0044] Therefore, by utilizing the fact that the third position is between the first and second positions, and during the process of rotating from the second position back to the third position, no force is transmitted between the operating handle 4 and the abutment 3. This allows the operating handle 4 to reset a certain distance before the elastic member 22 rebounds. As a result, when the elastic member 22 rebounds, the force of the elastic member 22 is first transmitted to the abutment 3. After the abutment 3 rotates a certain distance, it drives the operating handle 4 to reset. Therefore, this application can reduce the reset path of the operating handle 4 when the elastic member 22 rebounds, thereby reducing the risk of hitting the hand when the operating handle 4 rebounds quickly.

[0045] Please see Figures 1 to 3As shown, in some embodiments, the operating handle 4 and the abutment 3 have a first abutment position and a second abutment position, and the operating handle 4 can rotate freely between the first abutment position and the second abutment position relative to the abutment 3. When the operating handle 4 and the abutment 3 abut against each other at the first abutment position, the operating handle 4 drives the abutment 3 to rotate around the rotation axis 5 in the positive direction, causing the operating handle 4 to rotate from the first position to the second position. The abutment 3 presses down on the movable seat 21, causing the movable seat 21 to move down, and the elastic member 22 to undergo elastic deformation, thereby opening the wire hole 12 to allow the cable 6 to pass through the installation space 11, thereby realizing the electrical connection between the cable 6 and the connecting terminal.

[0046] In some embodiments, when the operating handle 4 is in the second position and rotates in the opposite direction to the abutment 3, the operating handle 4 and the abutment 3 abut against each other in the second abutment position. When the operating handle 4 is in the third position, it can rotate freely between the second and third positions, and there is no force transmission between the operating handle 4 and the abutment 3. At this time, the abutment 3 and the movable seat 21 are still in the state of the second position, that is, the abutment 3 abuts against the top surface of the movable seat 21, the elastic member 22 is in a compressed state, and the movable seat 21 opens the wire hole 12 to allow the cable 6 to pass through.

[0047] In some embodiments, when the operating handle 4 and the abutment 3 are abutted at the second abutment position, the operating handle 4 rotates in the opposite direction to drive the abutment 3 to rotate in the opposite direction to disengage from the movable seat 21, so that the elastic member 22 rebounds, the movable seat 21 moves upward, the abutment 3 rotates in the opposite direction and abuts against the operating handle 4 to the first abutment position, and the movable seat 21 presses the cable 6.

[0048] Therefore, by utilizing the fact that the operating handle 4 is rotatably positioned between the first and second abutment positions relative to the abutment member 3, when rotating between the first and second abutment positions, no force is transmitted between the operating handle 4 and the abutment member 3. This allows the operating handle 4 to reset a certain distance before the elastic member 22 rebounds. Consequently, when the elastic member 22 rebounds, the force of the elastic member 22 is first transmitted to the abutment member 3. After the abutment member 3 rotates a certain distance, it drives the operating handle 4 to reset. Thus, this application can reduce the reset path of the operating handle 4 when the elastic member 22 rebounds, thereby reducing the range of motion of the elastic member 22 during reset, and further reducing the risk of the operating handle 4 hitting the hand when it rebounds rapidly.

[0049] Please see Figures 1 to 4 As shown, in some embodiments, the top of the housing 1 has a rotating opening 16. The handle assembly is rotatably disposed within the rotating opening 16. When the operating handle 4 is in the first position, the operating handle 4 abuts against one end wall of the rotating opening 16, thereby limiting the reverse rotation of the operating handle 4 by the end wall of the rotating opening 16, thus facilitating the user to position the operating handle 4 in the first position.

[0050] In some embodiments, when the operating handle 4 is in the second position, the operating handle 4 abuts against the other end wall of the rotating port 16. Thus, the forward rotation of the operating handle 4 is limited by the other opposite end wall of the rotating port 16, thereby facilitating the user to position the second position of the operating handle 4.

[0051] In some embodiments, the rotation port 16 may be provided on the top of the body 14.

[0052] Please see Figures 1 to 4 As shown, in some embodiments, the abutment 3 is provided with a first abutting part 31 near the end of the operating handle 4. The operating handle 4 is provided with a first abutting wall 41 on the end wall near the abutment 3. When the operating handle 4 and the abutment 3 are abutted in the first abutting position, the first abutting part 31 abuts against the first abutting wall 41. At this time, the operating handle 4 is located in the first abutting position. Thus, by utilizing the abutting part 31 against the first abutting wall 41, when the user drives the operating handle 4 to rotate in the forward direction to the second position, the operating handle 4 can drive the abutment 3 to rotate in the forward direction, thereby driving the abutment 3 to press down the movable seat 21, causing the movable seat 21 to move down, the elastic member 22 to undergo elastic deformation, and the wire hole 12 to open so that the cable 6 can pass through the installation space 11 to realize the electrical connection with the terminal block.

[0053] In some embodiments, the operating handle 4 is provided with a second abutting portion 42 near the end of the abutting member 3. The abutting member 3 is provided with a second abutting wall 32 near the end wall of the abutting member 3. When the operating handle 4 and the abutting member 3 are abutted in the second abutting position, the second abutting portion 42 abuts against the second abutting wall 32. At this time, the operating handle 4 is in the third position. Thus, by utilizing the abutting portion 42 against the second abutting wall 32, the user drives the operating handle 4 to rotate in the opposite direction. When the operating handle 4 rotates from the third position to the first position, the operating handle 4 can drive the abutting member 3 to rotate in the opposite direction, thereby driving the abutting member 3 to disengage from the movable seat 21, causing the elastic member 22 to rebound, and the movable seat 21 to move upward, so that the movable seat 21 presses the cable 6.

[0054] Please see Figures 1 to 4As shown, in some embodiments, the operating handle 4 has a third abutment wall 43 on the end wall near the abutment member 3, and the abutment member 3 has a fourth abutment wall 33 on the end wall near the operating handle 4. When the operating handle 4 and the abutment member 3 are abutted in the first abutment position, the third abutment wall 43 and the fourth abutment wall 33 abut against each other, and the operating handle 4 is in the first abutment position. The third abutment wall 43 is located between the second abutment part 42 and the first abutment wall 41, and the fourth abutment wall 33 is located between the first abutment part 31 and the second abutment wall 32, allowing the operating handle 4 to rotate freely between the first abutment position and the second abutment position. This allows the operating handle 4 to be pre-reset relative to the abutment member 3, resulting in a smaller reset path and reset range for the operating handle 4 when the elastic member 22 subsequently rebounds and resets the abutment member 3, thus reducing the risk of the operating handle 4 hitting the hand during reset.

[0055] In some embodiments, the third abutment wall 43 and the fourth abutment wall 33 are concentrically arranged with the rotation shaft 5, thereby improving the smoothness of free rotation of the third abutment wall 43 and the fourth abutment wall 33 between the first abutment position and the second abutment position.

[0056] In some embodiments, the second abutment wall 32 and the fourth abutment wall 33 are smoothly transitioned, so that when the operating handle 4 rotates freely between the first abutment position and the second abutment position, the relative rotation between the operating handle 4 and the abutment member 3 is smoother.

[0057] Please see Figures 1 to 4 As shown, in some embodiments, the operating handle 4 may include a driving part 44 and a connecting part 45. The abutment 3 includes an abutment part 34 and a clamping part 35. The clamping part 35 has a clamping space 341. The connecting part 45 is located at the end of the driving part 44 near the abutment 3, and the clamping part 35 is located at the end of the abutment part 34 near the operating handle 4. The connecting part 45 can extend into the clamping space 341, and the connecting part 45 and the clamping part 35 can be rotatably connected via a rotating shaft 5. Thus, the user can drive the driving part 44, and through the rotatable connection of the connecting part 45 and the clamping part 35, drive the abutment 34 to rotate. Thus, by using the connecting part 45 and the clamping part 35 to achieve a rotatable connection between the operating handle 4 and the abutment 3, the smoothness of the rotatable connection between the operating handle 4 and the abutment 3 can be improved.

[0058] In some embodiments, a first abutment wall 41 is provided on the end wall of the connecting portion 45 near the abutment portion 34. A second abutment portion 42 protrudes from the connecting portion 45 toward the abutment portion 34. A third abutment wall 43 is provided on the end wall of the connecting portion 45 near the abutment portion 34. When the operating handle 4 is in the first position, the first abutment wall 41 is located above the third abutment wall 43, and the second abutment portion 42 is located below the third abutment wall 43.

[0059] In some embodiments, the second abutment wall 32 is provided on the end wall of the abutment portion 34 near the drive portion 44. The first abutment portion 31 protrudes from the abutment portion 34 toward the drive portion 44. The fourth abutment wall 33 is provided on the end wall of the abutment portion 34 near the drive portion 44. When the operating handle 4 is in the first position, the second abutment wall 32 is located below the fourth abutment wall 33, and the first abutment portion 31 is located above the third abutment wall 43.

[0060] Please see Figures 1 to 4 As shown, in some embodiments, the bottom of the movable seat 21 is provided with a sealing plate 211. The sealing plate 211 is arranged directly opposite the wire hole 12; when the operating handle 4 is in the first position and the elastic member 22 is in the relaxed state, the sealing plate 211 of the movable seat 21 blocks the wire hole 12, thereby preventing dust and debris from the outside of the electricity meter from entering the electricity meter, and also preventing electric shock.

[0061] In some embodiments, when the operating handle 4 is rotated to the second position, the abutment 3 presses down on the movable seat 21, causing the movable seat 21 to move down, the elastic member 22 undergoes elastic deformation, and the sealing plate 211 opens the wire hole 12, thereby realizing the electrical connection between the cable 6 and the connecting terminal.

[0062] Please see Figures 1 to 4 As shown, in some embodiments, a fixing member 17 is provided within the installation space 11. The fixing member 17 is fixed within the installation space 11. One end of the elastic member 22 abuts against the fixing member 17, and the other end of the elastic member 22 abuts against the movable seat 21. The extension direction of the elastic member 22 is the same as the movement direction of the movable seat 21. The elastic member 22 can be a spring, which can extend vertically. Thus, when the operating handle 4 and the abutting member 3 abut against each other in the first abutting position, and the operating handle 4 drives the abutting member 3 to rotate in the positive direction around the rotating shaft 5, the abutting member 3 presses down on the movable seat 21, causing the movable seat 21 to move downward. The elastic member 22 is compressed downward, and the wire hole 12 is opened to allow the cable 6 to pass through the installation space 11.

[0063] As can be seen from the above technical solution, this utility model has at least the following advantages and positive effects:

[0064] According to the electricity meter provided by this utility model, the operating handle 4 is rotatably positioned between the first and second abutment positions relative to the abutment member 3. That is, when rotating between the first and second abutment positions, no force is transmitted between the operating handle 4 and the abutment member 3. Therefore, the operating handle 4 can reset a certain distance before the elastic member 22 rebounds. Thus, when the elastic member 22 rebounds, the force of the elastic member 22 is first transmitted to the abutment member 3. After the abutment member 3 rotates a certain distance, it drives the operating handle 4 to reset. Therefore, this application can reduce the reset path of the operating handle 4 when the elastic member 22 rebounds, thereby reducing the range of movement of the elastic member 22 when it resets, and thus reducing the risk of the operating handle 4 hitting the hand when it rebounds quickly.

[0065] The above embodiments are merely illustrative examples of structures. The structures in each embodiment are not fixed combinations. In the absence of structural conflicts, the structures in multiple embodiments can be arbitrarily combined and used.

[0066] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
