Abstract
A dust-proof and moisture-proof electric meter box belongs to the technical field of electric meter boxes. The dust-proof and moisture-proof electric meter box comprises a box body and a box cover, wherein the box cover is provided with a visual window. The dust-proof and moisture-proof electric meter box is characterized in that a sealing ring is arranged at the contact of the box body and the box cover, and an L-shaped dust-proof cap is arranged on the visual window. The L-shaped dust-proof cap is connected with the box cover through flanges arranged at the left, right and lower sides of the visual window. Compared with the prior art, the dust-proof and moisture-proof electric meter box is reasonable in structural design, and the arrangement of the sealing ring makes the box body good in water-proofing and sealing performances so that potential safety hazards are avoided. When the electric meter box is not in use at ordinary times, the L-shaped dust-proof cap can cover the visual window to prevent debris and dust from entering the box body; and when the electric meter box needs to be used, the power consumption can be read by lifting the L-shaped dust-proof cap up to expose the visual window. The dust-proof and moisture-proof electric meter box has the advantages of being simple and reasonable in structure, low in manufacturing cost, convenient for users and meter readers to observe the readings of the meter, moisture-proof, longer in service life and broad in market prospects.
Description
Technical field
The utility model relates to a kind of structure of ammeter box, and especially a kind of structure of dust and moisture ammeter box belongs to the ammeter box technical field.
Background technology
Ammeter box is the protective device of ammeter, and municipal administration, residential quarter, telecommunications, electric power, rural power grids, factory, enterprise, office, heating power, fire-fighting etc. have the place of communal facility all to need to install ammeter, also just need ammeter box.Traditional ammeter box is made up of casing, case lid, runs into sleety weather, and water or moisture flow in the ammeter box from casing, case lid junction easily, conduct electricity after the ammeter moisture-sensitive like this, exist great potential safety hazard, and serviceable life is short.
On the other hand, present most of ammeter box all is installed in the open air, because it is long-time through exposing to the weather, phenomenons such as laying dust, fragmentation, weather stain can appear in the glass of ammeter box or plastics visual windows, so give and table look-up and internal unit brings certain trouble safely, even cause the ammeter box internal unit to break down and then whole ammeter box is burnt in short circuit.
Therefore, people are badly in need of a kind of dustproof ammeter box of protection against the tide again.
The utility model content
The purpose of this utility model is at above-mentioned the deficiencies in the prior art, and a kind of dust and moisture ammeter box is provided.
The purpose of this utility model is achieved through the following technical solutions: a kind of dust and moisture ammeter box, comprise casing and case lid, described case lid is provided with visual window, it is characterized in that, described casing, case lid contact position are provided with O-ring seal, and described visual window is provided with L type dust cover.
Described L type dust cover is connected with case lid by the chimb that is arranged on visual window left side, right side, downside.
Be equipped with the stopper slot that is complementary with L type dust cover on the chimb of described visual window left side, right side, downside setting, L type dust cover inserts in the stopper slot and is connected with case lid.
The utility model compared with prior art, reasonable in design, O-ring seal be arranged so that the casing waterproof, good airproof performance has been avoided potential safety hazard; When unmanned use at ordinary times, L type dust cover covers visual window, can prevent that foreign material, dust from entering in the casing, phenomenons such as laying dust, fragmentation, weather stain appear in the visual window of having avoided glass or plastics to make, when needs use, upwards mention L type dust cover and expose visual window, read power consumption.
The utility model is simple and reasonable, and low cost of manufacture has made things convenient for user and the person's of checking meter observation ammeter reading, also plays moisture-proof role, has prolonged serviceable life, has vast market prospect.
