Description

Technical Field

[0001] This utility model relates to the field of electricity meter technology, specifically a portable, recording miniature electricity meter. Background Technology

[0002] With the rapid development of industrial automation and power monitoring technology, miniature energy meters, as core devices for energy metering and data recording, are widely used in equipment debugging, energy consumption detection, and temporary power monitoring. Currently, most miniature energy meters on the market adopt a rectangular shell structure and are placed directly on a flat surface such as a workbench or the ground. Their display module is usually designed with a fixed tilt angle to the top surface of the shell.

[0003] The display screen and housing of existing micro energy meters are integrated and fixed. When the micro energy meter is placed on a low-lying workbench, the operator needs to frequently change the observation position to read the data accurately. Under conditions such as light refraction and insufficient ambient light, reading errors are easily caused. In addition, the bottom of the device is not equipped with a dedicated support structure, so it is easy to slide and shift when placed on an inclined plane, which poses a risk of falling and damage. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model provides a portable recording micro energy meter.

[0005] The technical solution of this utility model is as follows:

[0006] A portable recording micro energy meter includes an energy meter body, which includes a display module and a measurement module arranged sequentially in a front-to-back direction. A protective shell is fitted around the display module, and a first support adjustment plate is rotatably provided at the lower part of the protective shell. The length of the first support adjustment plate is adjustable, and the side of the first support adjustment plate near the protective shell is connected by a first connector. The first support adjustment plate has multiple insertion interfaces along its length.

[0007] A second support adjustment plate is rotatably mounted on the side of the first support adjustment plate away from the protective shell. An angle limiting rod is provided on one side of the second support adjustment plate. One end of the angle limiting rod is hinged to the second support adjustment plate, and the other end is inserted into one of the plug-in interfaces.

[0008] Preferably, the lengths of both the first and second support adjustment plates are greater than half the total length of the electricity meter body.

[0009] The specific structure of the first support adjustment plate is as follows: the first support adjustment plate includes a first adjustment plate rotatably connected to the protective shell and a second adjustment plate sleeved on the first adjustment plate. The second adjustment plate is detachably connected to the first adjustment plate through a second connector. The height of the display module can be adjusted by adjusting the length of the first support adjustment plate, and thus the display angle of the display module can be adjusted according to the actual situation.

[0010] The protective housing protects the frame of the display module and can be used to connect the first support adjustment plate, preventing the first support adjustment plate from directly contacting the display module and causing damage or drilling to the display module. Regarding the structure of the protective housing, the protective housing includes a middle frame and a front plate located on the front side of the middle frame. The front plate has an observation window. The display module is plugged into the protective housing, and the front side of the display module abuts against the front plate.

[0011] Furthermore, a baffle is detachably connected to the lower rear side of the mid-frame, and the mid-frame, baffle, and front plate form a clamping frame for holding the frame of the display module.

[0012] Preferably, the length of the second support adjustment plate is greater than the maximum length of the first support adjustment plate.

[0013] To facilitate adjustment of the second connecting plate on the outside of the first support adjusting plate, the second connecting piece and the plug interface are located on opposite sides of the first support adjusting plate.

[0014] Preferably, the upper part of the first adjusting plate is rotatably connected to the baffle via a rotating shaft, and the rotating shaft and the baffle are arranged parallel to each other.

[0015] The beneficial effects of this utility model are as follows:

[0016] The protective housing protects the frame of the display module and can be used to connect the first support adjustment plate, preventing the first support adjustment plate from directly contacting the display module and causing damage or drilling to the display module. The display module can be directly inserted into the frame formed by the middle frame and the front plate. The back of the display module is limited by the baffle, which wraps around the frame of the display module. The baffle is detachable, which facilitates the installation and removal of the display module.

[0017] The first support adjustment plate can adjust the tilt angle of the display module on the workbench from below. When the energy meter body is placed too low and it is inconvenient to observe the content of the display module, and it is necessary to adjust the display direction of the display module upward, the first support adjustment plate is connected to the baffle through the first connector in the vertical direction, so that the angle position of the first adjustment plate is fixed. After adjusting the position of the second adjustment plate, the total height of the first support adjustment plate is adjusted by tightening the second connector. The angle of the second support adjustment plate is adjusted according to the upward tilt angle of the display module, and the angle of the second support adjustment plate to the first support adjustment plate is fixed by the angle limiting rod, so that the first support adjustment plate, the second support adjustment plate and the angle limiting rod form a stable triangular structure.

[0018] A typical measurement module has multiple terminals at its rear end. By using the first and second support adjustment plates, the energy meter body is raised to a certain height, so that the terminals at the rear end of the measurement module can be higher than the plane, without affecting the wiring of the terminals or interfering with the angle of the wire harness contacting the ground after wiring.
