Description

Technical Field

[0001] The invention belongs to the technical field of electric power instruments and meters, and in particular relates to a quickly detachable electric energy meter and an electric energy meter box device. Background Art

[0002] An energy meter is a meter used to measure electrical energy, commonly known as an watt-hour meter, fire meter, or kilowatt-hour meter. As the demand for electricity increases, the use of energy meters is becoming more and more common, especially in outdoor environments.

[0003] However, the detachable design of traditional energy meters has certain safety hazards. For example, energy meters installed outdoors are easy to become targets of thieves due to their detachable characteristics. Traditional energy meters are usually fixed in the energy meter box by multiple bolts. Although this design is convenient for maintenance and replacement, it also makes the energy meter easy to be disassembled and stolen by unrelated personnel. This not only causes economic losses to the power company, but also may affect the normal electricity consumption of users. Secondly, the transparent observation window on the energy meter is generally exposed to the outside and is easily cracked by sunlight or eroded by rain.

[0004] In view of the deficiencies in the prior art, the present invention provides a quickly detachable electric energy meter and an electric energy meter box device, aiming to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to overcome the deficiencies in the prior art and to provide a quickly detachable electric energy meter and an electric energy meter box device, which can realize the rapid disassembly of the electric energy meter while preventing it from being stolen by other persons.

[0006] To achieve the above object, the present invention is implemented by adopting the following technical solutions:

[0007] In a first aspect, the present invention provides a quickly detachable electric energy meter, comprising:

[0008] An electric energy meter, comprising a transparent observation window, a mounting shell and a back plate, wherein the back plate is connected to the mounting shell;

[0009] And a mounting plate, wherein the mounting plate is provided with a mounting hole and is detachably connected to the back plate through a snap-fit ​​anti-theft mechanism.

[0010] Preferably, a rectangular slide slot hole is provided in both the mounting shell and the back plate, and a first vertical slide slot is provided in the rectangular slide slot hole.

[0011] Preferably, a mounting hole is provided on the mounting plate, the mounting hole is a circular hole, and a second limit block is installed on the hole wall of the mounting hole, and the cross-section of the second limit block is a disconnected ring; a second vertical slide groove is also provided on the mounting plate, and the top of the second vertical slide groove is connected to the mounting hole.

[0012] Preferably, the locking anti-theft mechanism comprises a protective plate and a sliding shaft, wherein:

[0013] The protective plate adjusts the visual range of the transparent observation window by translating outside the mounting shell;

[0014] The connecting end of the sliding shaft is connected to the protective plate, and the side of the sliding shaft is fixedly connected to a pair of guide blocks that slide in the first vertical slide groove, and the free end of the sliding shaft is movably connected to a pair of locking blocks, the pair of locking blocks are connected to the back plate, and the pair of locking blocks are moved closer to or away from each other through an elastic component and the sliding shaft; the cross-section of the pair of locking blocks is semicircular, and the arc portion of the locking block is provided with a rotating groove for sliding in the mounting hole.

[0015] Preferably, the elastic component includes a pair of compression springs, which are arranged in a transverse slide groove opened on the back plate, one end of the compression spring is connected to the guide block through a connecting block, and the other end is connected to the groove wall of the transverse slide groove, and the pair of transverse slide grooves are also connected to a first limit block to prevent the movement trajectory of the compression spring from being disordered.

[0016] Preferably, the external shape generated when the pair of engaging blocks contact each other is a circle, and the diameter of the circle is less than or equal to the inner diameter of the annular cross-section of the second limiting block.

[0017] Preferably, two of the rotation slots and two of the second limit blocks are provided.

[0018] In a second aspect, the present invention provides an electric energy meter box device, comprising an electric energy meter box and the quickly detachable electric energy meter described in the first aspect, wherein the mounting plate is installed in the electric energy meter box.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The present invention is designed with a snap-fit ​​anti-theft mechanism. First, by pushing the protective plate upwards, the visible range of the transparent observation window can be adjusted to protect the internal components from external influences, such as cracking due to direct sunlight or erosion by rain. At the same time, when the electric energy meter needs to be disassembled, the electric energy meter needs to be rotated one circle first, and then the protective plate is pushed downwards so that the sliding shaft moves into the second vertical sliding groove before the disassembly can be completed. Under normal circumstances, most people only think that the protective plate is only used to adjust the visible range of the transparent observation window, but ignore that the sliding shaft connected to the protective plate can also realize the disassembly of the electric energy meter. The present design realizes the disassembly of the electric energy meter through an ingenious structure, and further prevents theft, thereby improving the safety of the electric energy meter.
