Description

Technical Field

[0001] The utility model relates to the technical field of electric meter boxes, in particular to a household electric meter box with an anti-theft function. Background Art

[0002] The electric meter box refers to a shell used to install electric energy meters, which is commonly found in residential buildings, commercial buildings, industrial plants and other places. It is not only a carrier for installing electric meters, but also an important device for protecting electric meters and their surroundings. It is usually made of metal or plastic and has the characteristics of corrosion resistance, heat insulation, and waterproofness. Among them, the household electric meter box is a box used to install household electric meters.

[0003] At present, most of the existing household electricity meter boxes have a simple structure and are protected against theft by a box lock mechanism. The lock hole of the box lock mechanism is generally exposed to the outside, which makes it easy for criminals to pry open the box lock mechanism and steal the electricity used by the residents through the meter. After the theft, the criminals will restore the pried-open box lock mechanism to its original state, so it is difficult for power personnel to find traces of theft of residents' electricity, resulting in losses of residents' electricity. Utility Model Content

The upper and lower sides of the rear side of the inner wall of 8 and the upper and lower sides of the rear side of the inner wall of the movable groove 17 are both provided with a slide groove 18, and the inner walls of the two slide grooves 18 are jointly provided with a hidden mechanism with a variable covering range. The alarm mechanism includes a first spring 9, the upper end of the first spring 9 is fixedly connected to the upper side of the inner wall of the cavity 7, the lower end of the first spring 9 is fixedly connected to an insulating orifice plate 10, the insulating orifice plate 10 is made of phenolic resin glass fiber, the inner wall of the insulating orifice plate 10 is fixedly connected to an arc push rod 11, the arc push rod 11 is made of PVC, and the bottom surface of the insulating orifice plate 10 is fixedly connected to a first conductive plate 1 2, a second conductive plate 13 is fixedly connected to the lower side of the inner wall of the cavity 7, and the second conductive plate 13 is connected to the external power supply through a line. A bullet hole 14 is opened on the lower side of the inner wall of the cavity 7, and an alarm 26 is fixedly connected to the top surface of the block 6, and the alarm 26 is connected to the first conductive plate 12 through a connecting line, so that the first conductive plate 12 forms a closed state when in contact with the second conductive plate 13, thereby providing power for the activation of the alarm 26, and a limited block 15 is fixedly connected to the upper right side behind the alarm door 4, and the hidden mechanism includes two sliders 19, and the surfaces of the two sliders 19 are Slidingly connected with the corresponding slide groove 18, the front of the two sliders 19 are fixedly connected with a telescopic rod 20, the telescopic ends of the two telescopic rods 20 are sleeved with a second spring 21, the output ends of the two second springs 21 are commonly fixedly connected with a warning plate 22, and the rear side of the inner wall of the movable groove 17 is provided with a second box lock 16. The device has an anti-theft function. When the lawbreakers pry open the first box lock 5 on its surface and open the alarm door 4, the device will sound an alarm to remind the residents that someone has opened the meter box to steal the residents' electricity, so that the residents can take alarm measures to avoid losses in the residents' electricity use.

[0024] like Figure 2-3 As shown, in some embodiments, the surface of the insulating hole plate 10 is slidably connected to the inner wall of the cavity 7, the lower side of the arc push rod 11 is slidably connected to the inner wall of the bullet hole 14, and the surface of the second box lock 16 is slidably connected to the inner wall of the movable groove 17, which can ensure the normal operation of the device and improve the stability of the internal parts of the device during operation.

[0026] Working principle of the utility model: during the use of the device, the first box lock 5 is used to confuse criminals. When the criminals pry open the first box lock 5 and open the alarm door 4, the alarm door 4 will drive the limit block 15 to move, so that the limit block 15 releases the limit on the arc push rod 11. The arc push rod 11 is driven downward by the insulating hole plate 10 under the elastic potential energy of the first spring 9. The moving arc push rod 11 and the insulating hole plate 10 will drive the first conductive plate 12 to contact the second conductive plate 13. The first conductive plate 12 in contact with each other will form a closed circuit with the second conductive plate 13, providing power for the alarm 26 to make it emit an alarm sound, reminding the residents that there are criminals stealing the residents' electricity, which is convenient for the residents to take alarm measures. At the same time, the opening of the through port 3 is too small, which is not convenient for criminals to quickly steal the residents' electricity by wiring.

[0027] Afterwards, when the electrician needs to inspect and repair the electric meter installed inside, the electrician manually pushes the warning plate 22 backwards, so that the warning plate 22 squeezes the second spring 21 and the telescopic rod 20 to enter the hidden groove 8, and then pushes the warning plate 22 to the left. The warning plate 22 drives the slider 19 to move to the left on the inner wall of the slide groove 18 through the telescopic rod 20, so that the warning plate 22 enters the inside of the movable groove 17, which is convenient for the electrician to open the second box lock 16 with the key, so that the operator can open the hidden box door 2 by pulling the handle 24, thereby facilitating the operator to inspect and repair the electric meter installed inside. After inspecting and repairing the electrician after inspecting and repairing the electric meter installed inside, the electrician operates the device in the same reverse direction as above, and the hidden box door 2 can be closed and locked, so that the warning plate 22 enters the inside of the hidden groove 8 and returns to its original position under the elastic potential energy of the second spring 21. The parts not introduced in detail in this device are all prior art and will not be described in detail here.

[0028] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
