Abstract
The utility model relates to the ammeter case protector field, particularly to an air vent protector for an ammeter case. The air vent protector comprises an outer frame, an inner frame, and an air vent at the central position, wherein the outer edge of the inner frame is embedded in the air vent in the case plate; the outer frame is provided with a thread hole capable of fixing the outer frame upon the case plate, thereby facilitating and securing the assembling; the inner frame is internally provided with a plurality of parallel shielding sheets which are arranged in a spaced manner; the shielding sheets tilt outward and downward, thereby allowing the heat inside the ammeter case to go out through the gaps between the shielding sheets and realizing the heat radiation and cooling effect, shielding the air vent, and beautifying the appearance of the ammeter case; the inner frame is provided with two blocking rods at the inner side of the shielding sheets; the upper side edge and the lower side edge of the inner frame are respectively provided with embedded holes to match to the head and tail ends of the blocking rods; and a dustproof net and a moisture absorption cotton pad are arranged between the blocking rods and the shielding sheets, thereby better preventing dust, water, and foreign material.
Description
Technical field
The utility model relates to ammeter box protective device field, refers in particular to for a kind of ammeter box air hole protecting device.
Background technology
Now present ammeter box one-piece construction is closed, can produce hot gas during the ammeter running, and enclosed construction makes in the ammeter box and do not circulate, hot gas can't discharge, thereby ammeter the temperature inside the box is risen, 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 the ammeter box or rainwater splashes into, bring impact can for the normal operation of ammeter.
Summary of the invention
The purpose of this utility model is to provide a kind of 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 utility model adopts following technical scheme:
A kind of ammeter box air hole protecting device, described protective device are 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 the box plate; Be provided with some shielding plates and two pins in the internal frame body, be respectively equipped with the embedding hole that is 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 the internal frame body is parallel to each other and be spaced; The outside declivity of shielding plate makes between two shielding plates and forms ventilation gap.
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 the box plate.
The utility model is by being provided with some parallel and spaced shielding plates in internal frame body, the hot gas in the 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.
Description of drawings:
Accompanying drawing 1 is the structural representation of utility model;
Accompanying drawing 2 is the sectional view of utility model.
Embodiment:
Understand for the juror can be had purpose, feature and the function of the utility model further, hereby lift preferred embodiment and cooperate graphic being described in detail as follows:
See also shown in Figure 1, it is the structural representation of the preferred embodiment of the utility model, the utility model is to be 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 the box plate 4, outer frame body 1 is provided with the threaded hole that can be fixed on the 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 the internal frame body 2 can be discharged the hot gas in the ammeter box, reaches the effect of radiating and cooling; Shielding plate 5 outside declivities can not only effectively intercept dust, foreign material enter casing, can prevent that also rainwater from splashing into; Be provided with two pins 6 in the shielding plate inboard in the air vent 3, enclose and be respectively equipped with the embedding hole that is complementary with pin 6 head and the tail terminations on the upper and lower dual-side of frame; 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.
