Description

Technical Field

[0001] The present invention relates to the technical field of smart electric meters, and in particular to a smart electric meter with an anti-theft function. Background Art

[0002] As an important tool for modern electricity metering and management, smart meters use advanced sensors and metering technology. They can measure the electricity consumed by users with accuracy to very small units of electricity. When in use, the smart meter must first be fixed to a suitable installation position with fasteners, and then the smart meter must be connected to the power system through wires. When current passes through the wires, the smart meter can detect the current flowing through the wires, then convert it and convert the consumed electricity into a digital display screen.

[0003] Smart meters are mostly installed with bolts or screws during the installation process. Since bolts or screws are standard parts, tools for removing bolts or screws are also very common. This leads to non-staff members being able to use commercially available tools to privately dismantle smart meters. Since non-staff members lack business training, there is a risk of electric shock during private disassembly. In addition, the wiring terminals at the bottom of the meter are generally fastened to the wires with screws, and ordinary tools can also be used to privately dismantle and wire the wires. Private wiring may cause risks such as short circuits, which not only affects normal use but also causes electric shock accidents. Summary of the invention

[0004] Technical issues to be solved

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art, meet practical needs, and provide a smart electric meter with an anti-theft function to solve the above technical problems.

[0006] Technical Solution

[0007] In order to achieve the purpose of the present invention, the technical solution adopted by the present invention is:

[0009] The anti-theft cover comprises a guard plate covering the outside of the electric energy meter, the guard plate is arranged in a U shape, and both ends of the guard plate are provided with plug holes, a rectangular plug rod is inserted into the plug hole, and a compression spring is connected to the top of the rectangular plug rod;

[0010] The mounting base includes a base plate that is attached to the end of the electric energy meter, and positioning slots are provided on both sides of the bottom of the base plate. Both ends of the guard plate are inserted into the positioning slots. A storage groove corresponding to a rectangular plug rod is also provided above each of the positioning slots, wherein the rectangular plug rod and the compression spring are respectively located in the storage grooves.

[0011] As a further technical solution of the present invention, to protect the wiring terminals, first connect the wires to the wiring terminals, and use tools to lock the screws at the connections, then place the guard plate on the side of the wiring terminals, and push the guard plate close to the wiring terminals. At this time, the guard plates are respectively inserted into the inner sides of the positioning slots, which have a positioning effect on the two ends of the guard plate. When the guard plate is completely attached to the ends of the wiring terminals, the two ends of the guard plate are just completely inserted into the positioning slots. At this time, the compression spring in the receiving groove pushes the rectangular plug rod to slide to the bottom and insert it into the jack at the corresponding position of the end of the guard plate. By covering the outside of the wiring terminals with the guard plate, non-staff can be prevented from making private changes to the wires on the wiring terminals, thereby improving the anti-theft effect.

[0012] As a further technical solution of the present invention, a positioning cavity is provided on the side of the base plate, and the electric energy meter is fitted in the positioning cavity. The inner side of the positioning cavity is provided with countersunk bolt holes for placing bolts in a rectangular array. A groove seat is provided at one end of the electric energy meter close to the base plate, and an installation groove is provided at a position corresponding to the base plate and the groove seat. An elastic lock core is provided in the installation groove and is snap-fitted with the groove seat.

[0013] As a further technical solution of the present invention, the elastic lock core includes a rotary locking frame, a hollow rotary cavity is arranged on the upper part of the rotary locking frame, an outer locking claw is movably connected in the rotary cavity, an arc-shaped claw is arranged at one end of the outer locking claw, an axial hole is opened at the other end of the outer locking claw, and an installation shaft that rotates with the axial hole is arranged in the rotary cavity on the rotary locking frame, and the installation shaft passes through the inner side of the axial hole.

[0014] As a further technical solution of the present invention, a rotating shaft is provided at both ends of the rotating locking frame, and a cross clamp extending outward is provided at the end of the rotating shaft away from the rotating locking frame, which is convenient for workers to disassemble the connection by cooperating with professional tools. Disassembly holes corresponding to the rotating shaft are opened on both sides of the installation groove, and the ends of the disassembly holes extend to the inner side of the installation groove.

[0015] As a further technical solution of the present invention, the rotary locking frame is placed on the inner side of the mounting groove, the rotary shaft at the end of the rotary locking frame is inserted into the inner side of the disassembly hole and movably connected with the disassembly hole, and the rotary shaft is rotationally connected with the disassembly hole, so that the rotary locking frame can rotate on the inner side of the mounting groove with the rotary shaft as the axis.

[0016] As a further technical solution of the present invention, a positioning column is integrally provided on the upper side of the outer locking claw away from the rotating shaft, and a locking spring is sleeved on the outer side of the positioning column. The locking spring applies downward pressure to the outer locking claw to ensure that the end of the outer locking claw is always subjected to downward force, one end of the locking spring is in contact with the outer locking claw, and the other end is inserted into the limiting groove at the top of the installation groove.

[0017] As a further technical solution of the present invention, to place the electric energy meter into the positioning cavity, it is necessary to first align the groove seat with the installation groove, and as the electric energy meter moves, the groove seat is inserted into the inner side of the installation groove, and the end of the outer locking claw first contacts the groove seat. Since the end of the outer locking claw is arranged in an arc shape, the end of the outer locking claw first moves upward, and then the rotary locking frame contacts the groove seat. At the same time, the end of the rotary locking frame also rotates upward until the end of the rotary locking frame is located above the groove in the groove seat, and the locking spring pushes the rotary locking frame and the outer locking claw to be clamped into the groove on the groove seat. Since the elastic lock core is completely immersed in the inner side of the mounting seat, there are no fasteners after the electric energy meter is installed, thereby preventing non-staff from disassembling the electric energy meter privately.

[0018] As a further technical solution of the present invention, the groove seat is inserted into the inner side of the installation groove, the groove on the inner side of the groove seat is set upward, and the ends of the rotating locking frame and the outer locking claw are both clamped in the groove on the inner side of the groove seat. The electric energy meter is locked by clamping, and it is convenient for the staff to disassemble it.

[0019] As a further technical solution of the present invention, the protective plate is located at the outer bottom of the electric energy meter, and the protective plate covers the side of the terminal block to shield the screws at the connection between the terminal block and the wire, thereby improving the anti-theft effect.

[0020] (3) Beneficial effects:

[0021] A. In the present invention, the electric energy meter is first placed inside the positioning cavity, and the groove seat at the end of the electric energy meter is inserted into the inner side of the installation groove. As the installation groove moves, the outer locking claw and the rotating locking frame rotate upward one after another, respectively, to compress the locking spring above the outer locking claw. When the installation groove is completely located inside the installation groove, the locking spring applies downward pressure to the outer locking claw, so that the outer locking claw and the rotating locking frame are stuck in the groove of the groove seat. Since the locking structure is hidden inside the seat plate, the electric energy meter and the mounting seat can be disassembled after being fixed using professional tools, thereby improving the anti-theft effect of the smart meter;

[0022] B. In the present invention, the electric energy meter is first installed in the positioning cavity on the base plate, and then the wire is connected to the wiring terminal at the bottom of the electric energy meter, and then the guard plate covers the front end of the wiring terminal, and both ends of the guard plate are inserted into the positioning slots at the corresponding positions. When the end of the guard plate is completely inserted into the inner side of the positioning slot, the compression spring pushes the rectangular plug rod to move to the bottom, so that the bottom of the rectangular plug rod is inserted into the jacks opened at both ends of the guard plate. At this time, the guard plate completely covers the outside of the electric energy meter to protect the wiring terminal, and the bolts on the inner side of the wiring terminal cannot be moved, preventing non-professionals from privately wiring, and further improving the anti-theft effect of the smart meter;

[0023] C. In the present invention, when disassembling the electric energy meter, a special disassembly tool is inserted from the end of the disassembly hole, and a cross groove is provided at the end of the disassembly tool. The disassembly tool is moved close to the rotating shaft in the disassembly hole until the cross clamp at the end of the rotating shaft is inserted into the cross groove at the end of the disassembly tool. Then the disassembly tool is rotated, and the disassembly tool drives the rotary locking frame to rotate through the rotating shaft, so that the end of the rotary locking frame rotates upward. While the rotary locking frame rotates, the end of the outer locking claw is driven to rotate upward until the outer locking claw and the rotary locking frame are separated from the grooves of the groove seat respectively, and the electric energy meter is moved forward to be removed. The disassembly does not require complicated steps, but requires a special disassembly tool, which improves the anti-theft effect and is convenient for professionals to disassemble, shortens the time consumed during maintenance, and improves the replacement efficiency;

[0024] D. In the present invention, the seat plate is fixed to the installation position, and a number of bolts are passed through the countersunk bolt holes and threadedly connected to the installation position to fix the seat plate, and the ends of the bolts are completely immersed in the countersunk bolt holes. When the electric energy meter is installed in the positioning cavity, the electric energy meter blocks the bolts on the inner side of the countersunk bolt holes to prevent non-staff from disassembling them privately, thereby further improving the anti-theft effect.

The guard plate 71 is U-shaped, and both ends of the guard plate 71 are provided with plug holes, and a rectangular plug rod 72 is inserted into the plug hole. The top of the rectangular plug rod 72 is connected to a compression spring 73;

[0040] The mounting base 5 includes a base plate 51 that is attached to the end of the electric energy meter 1, and positioning grooves 56 are provided on both sides of the bottom of the base plate 51. Both ends of the protective plate 71 are inserted into the positioning grooves 56. A storage groove 57 corresponding to the rectangular plug rod 72 is also provided above each of the positioning grooves 56, wherein the rectangular plug rod 72 and the compression spring 73 are respectively located in the storage grooves 57.

[0041] By adopting the above technical scheme, the terminal 2 is protected. First, the wire is connected to the terminal 2, and the screws at the connection are locked by tools. Then the guard plate 71 is placed on the side of the terminal 2, and the guard plate 71 is pushed close to the terminal 2. At this time, the guard plates 71 are respectively inserted into the inner sides of the positioning slots 56, which have a positioning effect on the two ends of the guard plate 71. When the guard plate 71 is completely attached to the end of the terminal 2, the two ends of the guard plate 71 are just completely inserted into the positioning slots 56. At this time, the compression spring 73 in the receiving groove 57 pushes the rectangular plug rod 72 to slide to the bottom and insert it into the jack at the corresponding position of the end of the guard plate 71. By covering the outer side of the terminal 2 with the guard plate 71, non-staff can be prevented from making private changes to the wires on the terminal 2, thereby improving the anti-theft effect.

[0042] In this embodiment, please refer to Figure 5-8 A positioning cavity 52 is provided on the side of the base plate 51, and the electric energy meter 1 fits in the positioning cavity 52. ​​The inner side of the positioning cavity 52 is provided with countersunk bolt holes 53 for placing bolts in a rectangular array. A groove seat 4 is provided at one end of the electric energy meter 1 close to the base plate 51, and an installation groove 55 is opened at a position corresponding to the base plate 51 and the groove seat 4. An elastic lock core 6 is provided in the installation groove 55 and is engaged with the groove seat 4.

[0043] By adopting the above technical solution, the base plate 51 can be installed before installing the electric energy meter 1, and the base plate 51 can be placed at the installation position. Then, a number of bolts are passed through the countersunk bolt holes 53 and threadedly connected to the installation position. Since the countersunk bolt holes 53 are arranged in a stepped shape, when the bolts are connected to the installation position, the nuts at the ends of the bolts will be completely immersed in the countersunk bolt holes 53, and then the electric energy meter 1 can be installed in the positioning cavity 52 to completely cover the bolts in the countersunk bolt holes 53. The hidden setting of the installation bolts can improve the anti-theft effect.

[0044] In this embodiment, please refer to Figure 11-12 The elastic lock core 6 includes a rotating locking frame 61, a hollow rotating cavity is arranged on the upper part of the rotating locking frame 61, an outer locking claw 64 is movably connected in the rotating cavity, an arc-shaped claw is arranged at one end of the outer locking claw 64, and an axial hole 67 is opened at the other end of the outer locking claw 64, and a mounting shaft 63 rotatably matched with the axial hole 67 is arranged in the rotating cavity on the rotating locking frame 61, and the mounting shaft 63 passes through the inner side of the axial hole 67.

[0045] In this embodiment, both ends of the rotary locking frame 61 are provided with a rotary shaft 62, and the end of the rotary shaft 62 away from the rotary locking frame 61 is provided with a cross clamp extending outward, which is convenient for workers to disassemble the connection by cooperating with professional tools. Disassembly holes 54 corresponding to the rotary shaft 62 are opened on both sides of the installation groove 55, and the end of the disassembly hole 54 extends to the inner side of the installation groove 55.

[0046] In this embodiment, the rotary locking frame 61 is placed on the inner side of the mounting groove 55, and the rotary shaft 62 at the end of the rotary locking frame 61 is inserted into the inner side of the disassembly hole 54 and movably connected to the disassembly hole 54. The rotary shaft 62 is rotationally connected to the disassembly hole 54, so that the rotary locking frame 61 can rotate on the inner side of the mounting groove 55 with the rotary shaft 62 as the axis.

[0047] In this embodiment, a positioning column 66 is integrally provided on the upper side of the outer locking claw 64 away from the rotating shaft 62, and a locking spring 65 is sleeved on the outer side of the positioning column 66. The locking spring 65 applies downward pressure to the outer locking claw 64 to ensure that the end of the outer locking claw 64 is always subjected to downward force. One end of the locking spring 65 is in contact with the outer locking claw 64, and the other end is inserted into the limiting groove at the top of the installation groove 55.

[0048] By adopting the above technical solution, the electric energy meter 1 is placed in the positioning cavity 52. ​​It is necessary to first align the groove seat 4 with the installation groove 55, and as the electric energy meter 1 moves, the groove seat 4 is inserted into the inner side of the installation groove 55, and the end of the outer locking claw 64 first contacts the groove seat 4. Since the end of the outer locking claw 64 is arranged in an arc shape, the end of the outer locking claw 64 first moves upward, and then the rotating locking frame 61 contacts the groove seat 4. At the same time, the end of the rotating locking frame 61 also rotates upward until the end of the rotating locking frame 61 is located above the groove in the groove seat 4. The locking spring 65 pushes the rotating locking frame 61 and the outer locking claw 64 to be clamped into the groove on the groove seat 4. Since the elastic lock core 6 is completely immersed in the inner side of the mounting seat 5, there is no fastener after the electric energy meter 1 is installed, thereby preventing non-staff from disassembling the electric energy meter 1 privately;

[0049] When disassembling the electric energy meter 1, the staff needs to use professional tools for disassembly. The staff inserts the end of the tool which is set in an L shape as a whole into the disassembly hole 54, and the end of the tool is provided with a cross groove, until the cross clamp at the end of the rotating shaft 62 is inserted into the cross groove of the end of the tool, and the professional tool is rotated upward. The tool drives the rotating locking frame 61 and the outer locking claw 64 to rotate at the same time through the rotating shaft 62, so that the ends of the rotating locking frame 61 and the outer locking claw 64 are separated from the grooves on the groove seat 4, and then the electric energy meter 1 is moved forward and disassembled. During disassembly, there is no need to disassemble the bolts for a long time, so that the staff can quickly disassemble the electric energy meter 1.

[0050] In this embodiment, the groove seat 4 is inserted into the inner side of the installation groove 55, the groove inside the groove seat 4 is set upward, and the ends of the rotating locking frame 61 and the outer locking claw 64 are both clamped in the groove inside the groove seat 4. The electric energy meter 1 is locked by clamping, and it is convenient for the staff to disassemble it.

[0051] In this embodiment, the protective plate 71 is located at the outer bottom of the electric energy meter 1, and the protective plate 71 covers the side of the terminal block 2 to shield the screws at the connection between the terminal block 2 and the wire, thereby improving the anti-theft effect.

[0052] In this embodiment, the seat plate 51 is made of an integrally formed plastic plate, which ensures that the magnet attached to the side of the seat plate 51 can be attracted to the rectangular plug rod 72 and reduces the overall weight of the seat plate 51.

[0053] In this embodiment, the rectangular plug rod 72 is slidably connected to the inner side of the receiving groove 57, and the rectangular plug rod 72 adopts a rectangular magnet rod. The magnet is attached to the side of the seat plate 51 close to the rectangular plug rod 72. Due to the principle of opposite poles attracting each other, the magnet will attract when it moves upward, and the rectangular plug rod 72 moves upward on the inner side of the receiving groove 57, so that the bottom of the rectangular plug rod 72 is separated from the socket.

[0054] In this embodiment, a rubber pad 3 is provided on one side of the electric energy meter 1 close to the mounting seat 5 , and the rubber pad 3 is attached to the side of the positioning cavity 52 to fill the connection and prevent the electric energy meter 1 from shaking inside the positioning cavity 52 .

[0055] By adopting the above technical solution, the mounting base 5 is first installed, and a plurality of bolts are taken to pass through the countersunk bolt holes 53 and are threadedly connected to the mounting position. Since the countersunk bolt holes 53 are arranged in a stepped shape, when the bolts are connected to the mounting position, the nuts at the ends of the bolts will be completely immersed in the countersunk bolt holes 53, and then the electric energy meter 1 is installed into the positioning cavity 52 to completely cover the bolts in the countersunk bolt holes 53. As the electric energy meter 1 moves, the groove seat 4 at the end of the electric energy meter 1 is inserted into the inner side of the mounting groove 55, and the end of the outer locking claw 64 first contacts the groove seat 4. Since the end of the outer locking claw 64 is arranged in an arc shape, the end of the outer locking claw 64 first moves upward, and then the rotating locking frame 61 contacts the groove seat 4. At the same time, the end of the rotating locking frame 61 also rotates upward until the end of the rotating locking frame 61 is located above the groove in the groove seat 4, and the locking spring 65 pushes the rotating locking frame When the locking clasp 71 is in the closed position, the locking clasp 71 is in the closed position, and the locking clasp 71 is in the closed position, so that the locking clasp 71 is in the closed position, and the locking clasp 71 is in the closed position, so that the locking clasp 71 is in the closed position, and the locking clasp 71 is in the closed position, so that the locking clasp 71 is in the closed position, and the locking clasp 71 is in the closed position, so that the locking clasp 71 is in the closed position, and the locking clasp 71 is in the closed position, so that the locking clasp 71 is in the closed position, and the locking clasp 71 is in the closed position, so that the locking clasp 71 is in the closed position, and the locking clasp 71 is in the closed position, so that the locking clasp 71 is in the closed position, and the locking clasp 71 is in the closed position,
