Description

Technical Field

[0001] The utility model relates to the technical field of meter boxes, in particular to a three-phase single-meter non-metallic meter box. Background Art

[0002] The meter box is a device used to install meters and measure electricity. It usually includes electrical components such as meters, circuit breakers, fuses, etc., which are used to measure and control the use of electricity. The meter box is usually installed in the distribution room of residential or commercial buildings and is managed and maintained by the power company.

[0003] There are many wires inside the existing meter box, and cable ties are usually used to tighten and fix the multiple wires. However, this method not only affects the appearance of the interior of the box, but also requires the cable tie to be cut when a single wire is replaced, and the wire needs to be tightened and fixed with the cable tie again after the replacement, which makes the operation more cumbersome and inconvenient; and in order to improve the heat dissipation effect, the existing meter box has heat dissipation holes on the surface of the box. In order to prevent dust from entering the inside of the box through the heat dissipation holes during ventilation and heat dissipation, a dustproof net is usually provided at the heat dissipation holes. However, some fine dust cannot be completely blocked by the dustproof net, resulting in dust still entering the inside of the box after long-term use, causing the inside of the box to be affected.

[0012] Beneficial Effects

[0013] The above one or more technical solutions in a three-phase single-meter non-metallic meter box provided by the embodiment of the utility model have at least one of the following technical effects:

[0014] Through the above technical scheme, the wires are separately embedded in the wire clamping parts on the wire locking block to achieve split fixation of the wires, so there is no need to use cable ties to tighten and fix the wires, making the interior of the box more beautiful, and solving the problem that the cable tie needs to be cut when replacing a single wire, and the wire needs to be tightened and fixed with the cable tie again after the replacement, resulting in cumbersome and inconvenient operation; and through the dust sticking plate and the electrostatic sticker, the fine dust particles that the dustproof net cannot completely filter can be adsorbed, which solves the problem that some fine dust cannot be completely blocked by the dustproof net, resulting in dust still entering the box after long-term use, causing the interior of the box to be affected.

[0025] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] like Figure 1-6 As shown, it is a structural schematic diagram of a three-phase single-meter non-metallic meter box in a preferred embodiment of the utility model;

[0027] In this embodiment, it includes a box body 1 and a box door 2. The inner rear wall of the box body 1 is provided with a plurality of fixing blocks 3. A plurality of the fixing blocks 3 are detachably provided with wire locking blocks 4. Through the detachable structure, when the wire locking blocks 4 are damaged after long-term use, they are easy to be removed and replaced. The front part of the wire locking block 4 is provided with a wire clamping part 5, and the wire clamping part 5 is composed of two symmetrical arc-shaped plates. When in use, the wire is embedded in the wire clamping part 5, and the wire is clamped and fixed by the wire clamping part 5. Heat dissipation holes 6 are provided on both sides of the box body 1, and the heat dissipation holes 6 are provided with dustproof nets. Connecting plates 7 are provided on the top and bottom of the two inner side walls of the box body 1, and a connecting groove 8 is provided on the side of the connecting plate 7 away from the heat dissipation hole 6. A dust sticking plate 9 is embedded in the connecting groove 8, and the dust sticking plate 9 is detachably installed in the connecting groove 8. An electrostatic sticker 10 is provided on one end face close to the heat dissipation hole 6. The electrostatic sticker 10 is a multi-layer peelable structure. The electrostatic sticker 10 can adsorb fine dust particles that the dustproof net cannot filter. When the electrostatic sticker 10 adsorbs too much dust, the sticky plate 9 can be pulled out of the connecting groove 8, the outermost layer of the electrostatic sticker 10 can be torn off, and then the sticky plate 9 can be installed into the connecting groove 8 to continue to adsorb fine dust particles. The front and rear ends of the sticky plate 9 are not in contact with the box body 1 and the box door 2, so the heat dissipation hole 6 will not be completely blocked, thereby ensuring the heat dissipation effect; the wind blows into the heat dissipation hole 6 and first filters the larger dust particles through the dustproof net, and then the fine dust particles are adsorbed by the electrostatic sticker on the sticky plate 9. The wind after dust removal enters the box body 1 from the front and rear ends of the sticky plate 9 to ventilate and dissipate heat inside the box body 1.

[0028] In this embodiment, the fixing block 3 is provided with an insertion hole 11, and the rear of the locking block 4 is provided with an insertion rod 12, and the insertion rod 12 is inserted into the insertion hole 11. This structure can realize the detachable setting of the locking block 4.

Columns 15 are provided at the top and bottom of the two inner side walls of the box door 2. When connected, the box door 2 moves from top to bottom so that the columns 15 are embedded in the slots 14. The door 2 is fixed by this structure. A limit block 16 is rotatably provided at the bottom of the door 2. A limit plate 17 is provided on one side of the top of the limit block 16. The limit plate 17 is rotated to one side of the box body 1 by rotating the limit block 16, and the limit plate 17 is fitted with the box body 1 to limit the door 2.

[0030] In this embodiment, a plurality of mounting holes 18 are provided at the top of the inner rear wall of the box body 1, and a mounting bridge 19 is provided at the bottom of the inner rear wall of the box body 1. The mounting holes 18 are screw holes for installing the electric energy meter, and the mounting bridge 19 is for installing the circuit breaker switch.

[0031] In this embodiment, a wire inlet hole 20 and a wire outlet hole 21 are provided at the bottom of the box body 1. The wire inlet hole 20 is used for wire inlet, and the wire outlet hole 21 is used for wire outlet.

[0032] In this embodiment, an observation window 22 is provided on the top of the box door 2. The observation window 22 is made of a transparent acrylic plate to facilitate observation of the internal conditions of the metering box.

[0033] The utility model provides a three-phase single-meter non-metallic meter box, and its installation method, connection method or setting method are all common mechanical methods, and can be implemented as long as the beneficial effects can be achieved.
