Description

Technical Field

[0001] The utility model relates to the technical field of electric meters, in particular to a small electric meter which is easy to install. Background Art

[0002] A small electric meter generally refers to a device designed to measure and record electricity consumption, which is small in size. These meters are widely used in homes, small offices, apartment buildings, and other places where accurate measurement of electricity usage is necessary. Small electric meters typically feature a compact design, making them easy to install and carry. They may include a digital display or an analog needle, and the meter casing is typically made of durable, insulating materials. Ease of installation is a key feature of small electric meters.

[0004] Although the above-mentioned existing technology can realize the installation of the meter box, in actual use, on the one hand, the meter box is difficult to adapt to different meter boxes. Usually, the meter box is fixedly installed inside the meter box, which makes it difficult to install the meter box on different mounting racks, thereby reducing the convenience of meter box installation. On the other hand, the flexibility of meter cover installation is not high enough. Usually, after the wires are installed, multiple screws are used to fix the meter cover to the meter box, which increases the workload of the operator. Therefore, it does not meet the existing needs. In this regard, we propose a small electric meter that is easy to install. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model can improve the convenience of meter box installation through the slide groove and the threaded rod. When installing the meter box, the fixing plate is first adjusted according to the position of the mounting bracket inside the meter box. At this time, the fixing plate is pulled to move in the slide groove according to the position of the mounting bracket, and the threaded rod moves together in the fixing groove until the fixing plate is moved to a suitable position. At this time, the nut is rotated to move the nut toward the meter box through the thread on the threaded rod until the nut contacts the inner wall of the fixing groove, completing the position fixation of the fixing plate. The meter box is hung inside the meter box through the limit groove, and then the meter box is fixed to the mounting bracket inside the meter box with bolts, thereby improving the convenience of meter installation.

[0015] 2. The present invention can quickly install the watch cover through the snap-in plate and the snap-in slot. After the wires are connected, the wires of the display screen are connected to the electronic components first. At this time, the snap-in plate inside the watch cover is aligned with the opening of the snap-in slot and the watch cover is moved downward until the snap-in plate inside the watch cover enters the snap-in slot. The watch cover is continued to be moved downward until it is moved to a suitable position. At this time, the opening at the front end of the watch box is blocked by the watch cover, thereby improving the flexibility of the watch cover installation.

[0016] 3. The utility model increases the insulation of the electric meter by providing a rubber pad. After the meter box is fixed inside the meter box, the rubber pad at the rear end of the meter box contacts the inner wall of the meter box and is squeezed and deformed, so that a certain gap exists between the meter box and the meter box. At the same time, the rubber pad is an insulating material, which prevents the current from being transmitted to the meter box when the meter box leaks, thereby providing a certain safety guarantee for maintenance personnel. At the same time, the electronic components inside the meter box may generate certain vibrations when working. The rubber pad has good elasticity and cushioning properties, which can reduce the transmission of these vibrations and noise. BRIEF DESCRIPTION OF THE DRAWINGS
