Description

Technical Field

[0001] This application relates to the field of quick-disassembly technology for electricity meters, and in particular to a quick-disassembly type electricity meter. Background Technology

[0002] As the core equipment for electricity metering, electricity meters require regular calibration, replacement, or troubleshooting. Currently, most electricity meters are fixed to the mounting brackets of the distribution box using traditional bolts.

[0003] Regarding the aforementioned technologies, the inventors believe the following problems still exist: First, when installing an electricity meter, operators must use special tools such as screwdrivers to loosen the bolts one by one, which not only makes the process cumbersome but also time-consuming and labor-intensive. In addition, when installing an electricity meter, it is necessary to align the meter with the installation position before inserting it. This is very inconvenient when performing installation work in a narrow distribution box, and it is easy for installation misalignment to occur.

[0004] Secondly, after long-term use, dust, oil, or oxidation can easily accumulate at the plug-in holes of the electricity meter, leading to increased contact resistance, overheating, or even malfunctions, thus reducing transmission efficiency. Therefore, it is necessary to install additional protective components at the plug-in holes to further reduce its performance.

[0005] To address the aforementioned problems, the inventors proposed a quick-detachable electricity meter 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 a quick-detachable energy meter.

[0007] To solve the above problems, this utility model provides the following solution: a quick-detachable energy meter, including an energy meter body, a connecting mechanism on one side of the energy meter body, a protective mechanism shared by the connecting mechanism and the lower part of the energy meter body, the connecting mechanism including a mounting shell, an mounting plate fixedly mounted on the outer surface of the mounting shell, grooves on both inner walls of the mounting shell, two telescopic rods fixedly mounted on the inner walls of the opposite sides of the two grooves, springs movably sleeved on the outer surfaces of the multiple telescopic rods, a locking block slidably mounted on the telescopic ends of two telescopic rods located inside the same groove, the locking block rotatably mounted on one inner wall of the groove, a pull rod rotatably mounted on the side of the locking block near the telescopic rod, the end of the pull rod away from the locking block movably penetrating the mounting shell, a connecting plate fixedly mounted on one side of the energy meter body, and a fixing block cooperating with the locking block fixedly mounted on the side of the connecting plate facing away from the energy meter body.

[0008] Preferably, the protection mechanism includes two support plates, both of which are fixedly installed on the lower surface of the mounting shell. A rotating shaft is rotatably installed between the two support plates. A fixing plate is fixedly sleeved on the outer surface of the middle part of the rotating shaft. A pressing plate is fixedly installed on one side of the fixing plate. A protection plate is fixedly installed on the side of the pressing plate facing away from the fixing plate. The protection plate is in contact with the bottom surface of the electricity meter body. A plurality of through-type circular grooves are opened on the top surface of the protection plate. Rubber rings are fixedly installed inside the plurality of circular grooves.

[0016] 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.

[0017] Example: Figure 1-3 As shown, this utility model provides a quick-detachable electricity meter, including an electricity meter body 1. A connecting mechanism 2 is provided on one side of the electricity meter body 1. The connecting mechanism 2 can be installed on a structure such as a power distribution cabinet through the mounting plate 21. At the same time, the electricity meter body 1 can be installed and disassembled more conveniently through the cooperation of the fixing block 29 and the locking block 23, without the need to frequently remove bolts to disassemble and assemble the electricity meter body 1, thus improving the disassembly and assembly efficiency.

[0018] The lower part of the connecting mechanism 2 and the electricity meter body 1 are jointly provided with a protection mechanism 3. Through the protection mechanism 3, the electricity meter body 1 will push the pressing plate 37 during the installation process, thereby causing the pressing plate 37 to drive the protection plate 31 to rotate, so that the protection plate 31 rotates to fit against the bottom surface of the electricity meter body 1, so that the protection plate 31 protects the plug interface at the bottom of the electricity meter body 1, reduces the accumulation of dust, and improves its service life.

[0019] The connecting mechanism 2 includes a mounting shell 22, which serves as a housing to support and fix the components, thereby preventing them from falling off.

[0020] Mounting plate 21 is fixedly mounted on the outer surface of mounting housing 22. Mounting plate 21 is frame-shaped and fits onto the outer surface of mounting housing 22. By means of bolts or other structures, mounting plate 21 can be fixedly installed inside components such as power distribution cabinet, thereby fixing the connection mechanism 2.

[0021] The mounting shell 22 is hollowed out, which makes it easier for the fixing block 29 to be inserted between the locking blocks 23 and provides a better locking effect.

[0022] The inner walls on both sides of the mounting shell 22 are provided with grooves 20. The grooves 20 are rectangular and can accommodate two locking blocks 23, so that the locking blocks 23 are inserted into the interior of the grooves 20.

[0023] Two telescopic rods 25 are fixedly installed on the inner wall of each of the two grooves 20 on opposite sides. By using the telescopic rods 25, the rotating block 23 can be supported. At the same time, in cooperation with the spring 24, the block 23 can be kept in a protruding state.

[0024] Springs 24 are movably sleeved on the outer surface of multiple telescopic rods 25. By squeezing the locking block 23, the locking block 23 is kept in a protruding state, thereby locking the fixing block 29.

[0025] The telescopic ends of the two telescopic rods 25 located inside the same groove 20 are slidably mounted with a locking block 23. By using the locking block 23, the fixing block 29 can be locked in place, thereby keeping the electricity meter body 1 fixed.

[0026] Two grooves 27 are provided on one side of the locking block 23. The grooves 27 allow the telescopic rod 25 and the spring 24 to slide. The telescopic end of the telescopic rod 25 is slidably installed inside the groove 27. When the locking block 23 is pressed, it will press the telescopic rod 25, causing the telescopic rod 25 to slide inside the groove 27, thereby adapting to the angle change of the locking block 23.

[0027] One side of the locking block 23 is rotatably connected to the inner wall of the groove 20. The locking block 23 rotates inside the groove 20 via a hinge, thereby engaging the fixing block 29.

[0028] The locking block 23 is rotatably installed inside the groove 20. When it is squeezed, it will sink into the groove 20, thereby allowing the fixing block 29 to enter the mounting shell 22. When it is no longer squeezed, the spring 24 will cause it to bulge out, thereby locking the locking block 23.

[0029] A pull rod 26 is rotatably mounted on the side of the locking block 23 near the telescopic rod 25. By pulling the pull rod 26, the locking block 23 can be rotated, thereby releasing the locking block 23 from the fixed block 29, and thus the electricity meter body 1 can be disassembled smoothly.

[0030] The end of the pull rod 26 away from the locking block 23 moves through the mounting shell 22, allowing one end of the pull rod 26 to move on the outer surface of the mounting shell 22, thus making it easier to pull the pull rod 26 and further making it easier to disassemble the electricity meter body 1.

[0031] A connecting plate 28 is fixedly installed on one side of the electricity meter body 1, which can be fixedly connected to the electricity meter body 1 by bolts.

[0032] A fixing block 29 is fixedly installed on the side of the connecting plate 28 facing away from the power meter body 1. The fixing block 29 is used in conjunction with the card block 23.

[0033] The cross-sectional shape of the locking block 23 is set in a right trapezoid, and the cross-sectional shape of the fixing block 29 is set in a T-shape. By cooperating with the fixing block 29 and the locking block 23, the electricity meter body 1 can be installed and disassembled more conveniently without having to frequently remove the bolts to disassemble and install the electricity meter body 1, thus improving the disassembly and assembly efficiency.

[0034] The protective mechanism 3 includes two support plates 36, which can support the protective mechanism 3 and prevent it from falling off.

[0035] Both support plates 36 are fixedly installed on the lower surface of the mounting shell 22. The support plates 36 are fixedly connected to the mounting shell 22, which can prevent the support plates 36 and the protection mechanism 3 from falling off. The two support plates 36 can also support the fixed plate 35 below, allowing it to rotate between the two support plates 36.

[0036] A rotating shaft 34 is rotatably installed between the two support plates 36, which can rotate between the two support plates 36, thereby driving the central fixed plate 35 to rotate.

[0037] A fixing plate 35 is fixedly sleeved on the outer surface of the middle part of the rotating shaft 34. The fixing plate 35, as a plate-like structure, can be fixed to the outer surface of the rotating shaft 34, so that it rotates together with the rotating shaft 34. At the same time, it can drive the protective plate 31 to rotate. A pressing plate 37 is fixedly installed on one side of the fixing plate 35. The pressing plate 37 is made of flexible material. When the electricity meter body 1 is installed, it will push the pressing plate 37, causing the pressing plate 37 to drive the fixing plate 35 to rotate.

[0038] A protective plate 31 is fixedly installed on the side of the extrusion plate 37 facing away from the fixing plate 35. The extrusion plate 37 drives the protective plate 31 to rotate through the fixing plate 35, so that the protective plate 31 is in contact with the bottom surface of the electricity meter body 1, thus protecting the bottom surface of the electricity meter body 1.

[0039] The protection plate 31 and the pressing plate 37 are arranged perpendicularly to the protection plate 31. The protection plate 31 is attached to the bottom surface of the electricity meter body 1. This arrangement allows the protection plate 31 to rotate when the electricity meter body 1 presses the pressing plate 37, thus protecting the bottom surface of the electricity meter body 1.

[0040] The top surface of the protection plate 31 has multiple through-type circular grooves 32, through which wires can pass. The multiple circular grooves 32 are used in conjunction with the plug holes at the interface at the bottom of the energy meter body 1, so that the wires can be inserted into the interface at the bottom of the energy meter body 1.

[0041] Rubber rings 33 are fixedly installed inside the multiple circular grooves 32. The rubber rings 33 can reduce dust adhesion at the insertion holes.

[0042] Working principle: First, install the mounting plate 21 in a suitable position, then fix the connecting plate 28 to the electricity meter body 1, and then insert the fixing block 29 into the mounting shell 22. The protrusions on both sides of the fixing block 29 press against the locking blocks 23 on both sides, causing the locking blocks 23 to rotate and press against the telescopic rod 25 and the spring 24, causing the telescopic rod 25 and the spring 24 to slide inside the slide groove 27, and causing the locking blocks 23 to be completely submerged in the groove 20, so that the fixing block 29 is completely inserted into the mounting shell 22. After that, the protrusions press against the locking blocks 23, and the spring 24 will reset, thereby driving the telescopic rod 25 to extend, thereby driving the locking blocks 23 to rotate and protrude outward, thereby locking the protrusion of the fixing block 29, and thus fixing the electricity meter body 1.

[0043] When it is necessary to disassemble the electricity meter body 1, the pull rods 26 on both sides can be pulled, causing the pull rods 26 to rotate the locking blocks 23 on both sides, thereby releasing the locking of the fixing block 29, allowing the fixing block 29 to be separated from the mounting shell 22, and thus the electricity meter body 1 can be disassembled.

[0044] As the electricity meter body 1 is installed, it moves towards the mounting housing 22, pushing the pressing plate 37. This pushes the pressing plate 37, causing the fixing plate 35 to rotate. The fixing plate 35 rotates between the two support plates 36 via the rotating shaft 34, thereby causing the protection plate 31 to rotate. Once the electricity meter body 1 is installed, the protection plate 31 will fit against the bottom surface of the electricity meter body 1. At the same time, the circular groove 32 will align with the insertion hole on the bottom surface of the electricity meter body 1, allowing the wire to pass through the circular groove 32 and connect to the electricity meter body 1. Meanwhile, the rubber ring 33 inside the circular groove 32 will wrap around the wire, sealing the connection between the wire and the insertion hole and reducing the entry of dust.

[0045] 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.
