Description

Technical Field

[0001] This application relates to the field of electricity meter structure technology, and in particular to an electricity meter with an electric shock protection structure. Background Technology

[0002] An electricity meter, also known as a kilowatt-hour meter, is a key device installed at the user's end to measure electricity consumption.

[0003] Regarding the aforementioned technologies, the inventors believe the following problems still exist: First, most existing electricity meters have simple flip-top or snap-on covers. These covers lack a locking mechanism, making them prone to accidental opening due to collisions or workers touching them during daily use. This exposes the wiring terminals and poses a risk of electric shock if people accidentally touch them.

[0004] Secondly, when the wires at the terminals of the electricity meter become loose due to external pulling or other reasons, the built-in cover cannot protect the loose and exposed terminals in time, and there is still a risk of electric shock. At the same time, the existing electricity meter's built-in cover has poor sealing performance with the meter body, and foreign objects such as dust and metal shavings can easily enter the wiring cavity and accumulate at the terminals, which can easily cause short circuits at the terminals, leading to electric shock or equipment damage.

[0005] To address the aforementioned problems, the inventors proposed an electricity meter with an electric shock protection structure to solve these issues. Utility Model Content

[0006] In order to improve the problem that some existing devices are inconvenient to use, the purpose of this utility model is to provide an energy meter with an electric shock protection structure.

[0007] To solve the above problems, this utility model provides the following solution: an electricity meter with an anti-electric shock protection structure, including an electricity meter body, an anti-electric shock mechanism provided at the lower part of the electricity meter body, multiple protective mechanisms provided on the bottom surface of the anti-electric shock mechanism, the anti-electric shock mechanism including a cover plate body, the cover plate body being snapped into the lower part of the electricity meter body, a sealing strip provided on the side of the electricity meter body near the cover plate body, multiple permanent magnets fixedly installed on the inner wall of one side of the cover plate body, an iron sheet cooperating with the permanent magnets provided at the lower part of one side of the electricity meter body, two insertion rods fixedly installed on the inner wall of one side of the cover plate body, and two slots cooperating with the insertion rods provided at the lower part of the electricity meter body.

[0008] Preferably, the protection mechanism includes multiple limiting plates. The lower part of the cover plate body is provided with multiple through slots that cooperate with the plug interface of the energy meter body. An inner groove is opened between the inner walls on both sides of the multiple through slots. A rotating shaft is rotatably installed between the upper and lower inner walls of the multiple inner grooves. A rotating rod is movably sleeved on the outer surface of the multiple rotating shafts. One side of each of the multiple rotating rods is fixedly connected to one side of the multiple limiting plates. A buckle is fixedly installed on the side of the multiple limiting plates near the rotating rod. A slot for cooperating with the buckle is opened on the inner wall of the multiple inner grooves. An arc-shaped push plate is fixedly installed on one side of the multiple limiting plates. The limiting plates and the push plates are perpendicularly distributed.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, by setting up an anti-electric shock mechanism, uses the permanent magnet of the anti-electric shock mechanism to cooperate with the iron plate to fix the cover plate body of the electricity meter body. At the same time, by using the plug rod to cooperate with the slot, it can prevent the cover plate body from being opened directly by sliding, reducing the risk of electric shock caused by accidental contact.

[0010] 2. This utility model, by setting up a protection mechanism and using the limiting plate of the protection mechanism, can protect the wiring after installation.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example: Figure 1-4 As shown, this utility model provides an energy meter with an anti-electric shock protection structure, including an energy meter body 1, which uses existing mature technology.

[0019] The lower part of the electricity meter body 1 is provided with an anti-electric shock mechanism 2. The permanent magnet 24 of the anti-electric shock mechanism cooperates with the iron plate 22 to fix the cover body 23 of the electricity meter body 1. At the same time, the plug 25 cooperates with the slot 21 to prevent the cover body 23 from being opened directly by sliding, reducing the risk of electric shock caused by accidental contact.

[0020] The bottom surface of the anti-electric shock mechanism 2 is equipped with multiple protection mechanisms 3. The limit plate 34 of the protection mechanism 3 can protect the installed line. At the same time, the buckle 36 can fix the line to prevent the line from being exposed due to external forces such as bending, thereby reducing the possibility of electric shock when workers operate the electricity meter body 1.

[0021] The anti-electric shock mechanism 2 includes a cover plate body 23, which works in conjunction with the electricity meter body 1 to protect the wiring copper busbar from electric shock.

[0022] The cover plate body 23 is fitted into the lower part of the electricity meter body 1, so that it can be fixed by the permanent magnet 24 and the iron plate 22. At the same time, by the insertion rod 25 and the slot 21, the cover plate body 23 can be prevented from being opened directly by sliding, reducing the risk of electric shock caused by accidental contact.

[0023] A sealing strip 26 is provided on the side of the electricity meter body 1 near the cover plate body 23. The sealing strip 26 can seal the gap between the electricity meter body 1 and the cover plate body 23, reducing the occurrence of dust and other impurities inside the electricity meter body 1.

[0024] Multiple permanent magnets 24 are fixedly installed on one inner wall of the cover plate body 23. The permanent magnets 24 can cooperate with the iron sheet 22 to fix the cover plate body 23 of the electricity meter body 1, reducing the risk of electric shock caused by accidental contact or other situations that may cause the cover plate to open.

[0025] A metal plate 22 is provided on the lower side of one side of the electricity meter body 1 to work with a permanent magnet 24. The metal plate 22 can work with the permanent magnet 24 to achieve a magnetic attraction effect and fix the cover plate body 23 that comes with the electricity meter body 1.

[0026] Two insert rods 25 are fixedly installed on one inner wall of the cover plate body 23. The insert rods 25 are made of rigid material. The two permanent magnets 24 and the two insert rods 25 are distributed in a mirror image. The two insert rods 25 are distributed on both sides of the two permanent magnets 24. By distributing the two permanent magnets 24 and the two insert rods 25 in a mirror image, the force can be distributed more evenly, thereby improving the stability of the cover plate body 23 during installation.

[0027] The lower part of the electricity meter body 1 is provided with two slots 21 that cooperate with the plug rod 25. The slots 21 can fix the plug rod 25. The plug rod 25 and the slots 21 are connected in a damped sliding manner, which makes it require more force to open, thereby reducing accidental contact that could cause the cover body 23 to open and thus prevent electric shock.

[0028] The protection mechanism 3 includes multiple limit plates 34, which are arc-shaped and can be adapted to the shape of the line to limit the line and protect the line after installation. This prevents the line from being exposed due to external forces such as bending, thereby reducing the risk of electric shock when workers operate the electricity meter body 1.

[0029] The lower part of the cover plate body 23 is provided with multiple through slots 31 that are used in conjunction with the plug interface of the electricity meter body 1. The through slots 31 can accommodate the wires, allowing the wires to pass through the through slots 31 and connect to the electricity meter body 1.

[0030] The cover plate body 23 is sleeved on the lower part of the electricity meter body 1. Multiple through slots 31 are located below the plug interface of the electricity meter body 1. This not only protects the copper busbars of the wiring, but also protects the circuit, reducing the risk of electric shock caused by the exposure of the internal copper wires due to external forces.

[0031] The cross-sectional shape of the through groove 31 is U-shaped. The U-shaped through groove 31 can enclose the line, thereby limiting and protecting the line through the limiting plate 34. One side of the through groove 31 is hollowed out, so that the line enters the through groove 31 from the opening.

[0032] An inner groove 33 is provided between the inner walls on both sides of the multiple through grooves 31. The inner grooves 33 are arranged in a stepped shape. The inner grooves 33 where the rotating shaft 38 is installed are deeper, while the inner grooves 33 where the slot 32 is provided are shallower.

[0033] A rotating shaft 38 is rotatably installed between the upper and lower inner walls of multiple inner grooves 33, so that the rotating shaft 38 can rotate inside the inner groove 33, thereby driving the limiting plate 34 to rotate.

[0034] Multiple rotating shafts 38 are movably fitted with rotating rods 37 on their outer surfaces, so that when they rotate through the rotating shafts 38, they can drive the limiting plate 34 to rotate, and thus the limiting plate 34 limits the circuit.

[0035] One side of each of the multiple rotating rods 37 is fixedly connected to one side of each of the multiple limiting plates 34, so that the rotating rods 37 drive the limiting plates 34 to rotate, and thus when they rotate, they drive the limiting plates 34 to rotate synchronously.

[0036] The two limiting plates 34 located inside the same through slot 31 are mirror-distributed, so that the two limiting plates 34 inside the same through slot 31 can be used together to limit and protect the circuit inside the through slot 31.

[0037] Multiple limiting plates 34 are fixedly installed with buckles 36 on the side near the rotating rod 37. As a mature existing technology, the buckles 36 can be locked inside the slot 32 to fix the limiting plates 34 and prevent the limiting plates 34 from moving.

[0038] The buckle 36 is an elastic buckle, preferably made of elastic material, which makes it easier to snap into the slot 32, thereby increasing the stability between it and the slot 32.

[0039] The inner walls of multiple inner grooves 33 are provided with slots 32 that cooperate with buckles 36. The slots 32 are grooves inside the inner grooves 33 and can cooperate with buckles 36. The slots 32 are provided with protrusions that cooperate with buckles 36, so that buckles 36 can be locked and prevented from falling off. At the same time, the buckles 36 can be used to fix the wires and prevent the wires from being exposed due to external forces such as bending, thereby reducing the possibility of electric shock when workers operate the electricity meter body 1.

[0040] An arc-shaped push plate 35 is fixedly installed on one side of multiple limit plates 34, and the other limit plates 34 are fixedly connected to one side, so that they can drive the limit plates 34 to move. The limit plates 34 and the push plates 35 are perpendicularly distributed. When the line is inserted into the through groove 31, it will squeeze the push plate 35. Since the push plate 35 is perpendicular to the limit plate 34, the push plate 35 rotates around the pivot 38, which in turn drives the rotating rod 37 to rotate. The rotating rod 37 drives the limit plate 34 to rotate, thereby surrounding the line in the opposite direction and limiting and protecting the line.

[0041] Working principle: First, connect the line to the copper busbar at the bottom of the meter body 1. Then, put the cover plate 23 of the anti-electric shock mechanism 2 on the bottom of the meter body 1, so that it covers the bottom of the meter body 1. At the same time, insert the plug 25 into the corresponding slot 21 and bring the iron plate 24 close to the permanent magnet 22, so that the cover plate 23 is fixed to the bottom of the meter body 1, protecting the copper busbar. The sealing strip 26 can seal the inside to reduce dust entry.

[0042] When the cover plate body 23 is installed, multiple limiters are connected through multiple through slots 31, and the opened limit plate 34 enters the through slot 31, allowing the wire to move inside the through slot 31. When the wire is stuck inside the through slot 31, it will squeeze the push plate 35. Since the push plate 35 is perpendicular to the limit plate 34, the push plate 35 rotates around the pivot 38, which in turn drives the rotating rod 37 to rotate. The rotating rod 37 rotates inside the inner slot 33, and drives the limit plate 34 to rotate, thereby surrounding the wire in the reverse direction, limiting and protecting the wire. At the same time, the buckle 36 on the back of the limit plate 34 will engage with the slot 32, thereby fixing the limit plate 34. When it is necessary to disassemble the cover plate body 23, the limit plate 34 can be disassembled by pushing the wire in the reverse direction.

[0043] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
