Abstract
The present invention relates to ammeter box protector field, refer in particular to for a kind of ammeter box air hole protecting device, described protector is divided into outer frame body, internal frame body and middle air vent, the perimeter wall of internal frame body is nested in the ventilating opening on box plate, outer frame body is provided with the screwed hole that can be fixed on box plate, makes assembling simple, firm; In internal frame body, be provided with some parallel and spaced shielding plates, the outside declivity of shielding plate can be discharged the hot gas in ammeter box the gap between shielding plate, thereby reaches radiating and cooling effect, and has covered air vent and the outward appearance of beautifying ammeter box. In internal frame body, be provided with two pins in shielding plate inner side, on the upper and lower dual-side of internal frame body, be respectively equipped with the embedding hole matching with pin head and the tail termination; Between pin and shielding plate, accompany Air Filter and the absorbent cotton sheet in enclosed ventilation hole, more effectively play the effect of dustproof, waterproof, anti-foreign material.
Description
Technical field
The present invention relates to ammeter box protector field, refer in particular to for a kind of ammeter box air hole protecting device.
Background technology
Now current ammeter box overall structure is closed, when ammeter running, can produce hot gas, and enclosed construction makes not circulate in ammeter box, hot gas cannot discharge, thereby make temperature rise in ammeter box, not only may cause ammeter short circuit, also can shorten the service life of ammeter. On the casing of part ammeter box, offer little air vent, 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 work of ammeter.
Summary of the invention
The object of the present invention is to provide one can make 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 protector 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; In internal frame body, be provided with some shielding plates and two pins, on the upper and lower dual-side of internal frame body, be respectively equipped with the embedding hole matching with pin head and the tail termination; Between shielding plate and pin, can accompany Air Filter and the absorbent cotton sheet in enclosed ventilation hole.
Shielding plate in internal frame body is parallel to each other and be spaced; The outside declivity of shielding plate, makes to form ventilation gap between two shutters.
Pin is made up 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 screwed hole that can be fixed on box plate.
The present invention, by be provided with some parallel and spaced shielding plates in internal frame body, can discharge the hot gas in ammeter box, thereby reaches radiating and cooling effect the gap between shielding plate, and has covered air vent and the outward appearance of beautifying ammeter box; Between pin and shielding plate, accompany Air Filter and the absorbent cotton sheet in enclosed ventilation hole, more effectively play the effect of dustproof, waterproof, anti-foreign material.
Brief description of the drawings:
The structural representation that accompanying drawing 1 is invention;
The sectional view that accompanying drawing 2 is invention.
Detailed description of the invention:
In order to make juror can the present invention's object, feature and function be had further and be understood, 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 protector, internal frame body 2 is nested in the ventilating opening on box plate 4, outer frame body 1 is provided with the screwed 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; In air vent 3, be provided with two pins 6 in shielding plate inner side, enclose and on the upper and lower dual-side of frame, be respectively equipped with and embedding hole that pin 6 head and the tail terminations match; Between pin 6 and shielding plate 5, 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 made up of plagioclase bar, horizontal quarter butt and vertical quarter butt, and plagioclase bar and horizontal quarter butt surround triangular shape, can expand Air Filter and absorbent cotton sheet holding area. In the time that Air Filter 7 needs cleaning or absorbent cotton sheet 8 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, 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.
Claims (2)
