Abstract
The invention relates to the field of electric meter box protection devices, in particular to a ventilation hole protection device used for an electric meter box. The protection device comprises an outer frame body, an inner frame body and a middle ventilation hole, wherein the outer edge wall of the inner frame body is embedded in a ventilation opening in a box body plate, the outer frame body is provided with a threaded hole capable of fixing the outer frame body to the box body plate so that assembling can be simple and firm, the inside of the inner frame body is provided with a plurality of parallel shielding pieces distributed at intervals, the shielding pieces are inclined downwards and outwards so that heat in the electric meter box can be exhausted from gaps among the shielding pieces, radiating and temperature reducing effects are achieved, the ventilation hole is blocked and appearance of the electric meter box is beautified. Two stopping rods are arranged on the inner side of the shielding pieces in the inner frame body, and the upper side edge and the lower side edge of the inner frame body are respectively provided with an embedment hole matched with the head ends and the tail ends of the stopping rods. A dustproof net and a moisture-absorption cotton piece are arranged between the stopping rods and the shielding pieces and are used for sealing the ventilation hole, and dustproof, waterproof and material-proof functions can be effectively achieved.
Description
Technical field
The present invention relates to ammeter box protective device field, refer in particular to for a kind of ammeter box air hole protecting device.
Background technology
Now current ammeter box one-piece construction is closed, during the ammeter running, can produce hot gas, and enclosed construction makes not circulate in ammeter box, hot gas can't discharge, thereby make ammeter the temperature inside the box increase, not only may cause the ammeter short circuit, also can shorten the serviceable life of ammeter.Offer little air vent on the casing of part ammeter box, but ventilation effect is general, and often has dust and winged insect and enter in ammeter box or rainwater splashes into, bring impact can to the normal operation of ammeter.
Summary of the invention
The object of the present invention is to provide a kind ofly can make the ammeter box inner air flow and radiating and cooling, and can effectively prevent dust, the ammeter box air hole protecting device of waterproof, anti-foreign material.
For achieving the above object, the present invention adopts following technical scheme:
A kind of ammeter box air hole protecting device, described protective device is divided into outer frame body, internal frame body and middle air vent, and the perimeter wall of internal frame body is nested in the ventilating opening on box plate; Be provided with some shielding plates and two pins in internal frame body, be respectively equipped with the embedding hole be complementary with pin head and the tail termination on the upper and lower dual-side of internal frame body; Can accompany Air Filter and the absorbent cotton sheet in enclosed ventilation hole between shielding plate and pin.
Shielding plate in internal frame body is parallel to each other and be spaced; The outside declivity of shielding plate, make to form ventilation gap between two shutters.
Pin is comprised of plagioclase bar, horizontal quarter butt and vertical quarter butt, and plagioclase bar and horizontal quarter butt surround triangular shape.
Outer frame body is provided with the threaded hole that can be fixed on box plate.
The present invention is by being provided with some parallel and spaced shielding plates in internal frame body, the hot gas in ammeter box can be discharged the gap between shielding plate, thereby reach the radiating and cooling effect, and covered air vent and the outward appearance of beautifying ammeter box; Accompany Air Filter and the absorbent cotton sheet in enclosed ventilation hole between pin and shielding plate, more effectively play the effect of dustproof, waterproof, anti-foreign material.
the accompanying drawing explanation:
Accompanying drawing 1 is the structural representation of invention;
Accompanying drawing 2 is the sectional view of invention.
embodiment:
Understand for the juror can be had the present invention's purpose, feature and function further, hereby lift preferred embodiment and coordinate graphic being described in detail as follows:
Refer to shown in Fig. 1 and Fig. 2, it is the structural representation of the present invention's preferred embodiment, the present invention is divided into outer frame body 1, internal frame body 2 and middle air vent 3 about described protective device, internal frame body 2 is nested in the ventilating opening on box plate 4, outer frame body 1 is provided with the threaded hole that can be fixed on box plate 4, assembling is simple, and structure is fixed; The gap that is provided with 5 of some parallel and spaced shielding plate 5, two shielding plates in internal frame body 2 can be discharged the hot gas in ammeter box, reaches the effect of radiating and cooling; The outside declivity of shielding plate 5, can not only effectively intercept dust, foreign material enter casing, also can prevent that rainwater from splashing into; Be provided with two pins 6 in air vent 3 in the shielding plate inboard, enclose on the upper and lower dual-side of frame and be respectively equipped with and embedding hole that pin 6 head and the tail terminations are complementary; 5 of pin 6 and shielding plates can accompany Air Filter 7 and the absorbent cotton sheet 8 in enclosed ventilation hole, the effect of can play better dustproof, waterproof, putting foreign material.
Pin 6 is comprised of plagioclase bar, horizontal quarter butt and vertical quarter butt, and plagioclase bar and horizontal quarter butt surround triangular shape, can enlarge Air Filter and absorbent cotton sheet holding area.When Air Filter 7 needs cleaning or absorbent cotton sheet 8 to need to change, only need two fingers to press pin 6 by plagioclase bar and horizontal quarter butt, the angle of plagioclase bar and horizontal quarter butt reduces, the pin whole height dwindles, extract out from the embedding hole of internal frame body the head and the tail termination of pin, and Air Filter and absorbent cotton sheet can take out.
