Abstract
The invention discloses an air pressure signal lamp switch. The switch comprises a switch body, wherein a briquette is arranged in the cavity of the switch body; an electrode seat is arranged above the briquette, and a gasket is arranged between the briquette and the electrode seat; two L-shaped electrodes are arranged in the cavity of the electrode seat, horizontal ends of the two electrodes are connected into a whole, vertical ends of the two electrodes are arranged in the electrode seat in a sliding way and penetrate through the electrode seat; a cloth clamp membrane is arranged under the briquette; a top block is arranged in the briquette in a sliding way; an arc face at the lower end of the top block is supported against the cloth clamp membrane; the upper end of the top block and the horizontal ends of the electrodes are connected into a whole; a seal ring is arranged in the opening of the lower part of the cavity of the switch body; and a through cavity is formed in the center of the seal ring. The air pressure signal lamp switch has a simple structure and is easy to realize, and the air tightness of the air pressure signal lamp switch is improved, thus a signal lamp can be quickly lightened, the automatic reset of the air pressure signal lamp switch is realized, and the safety of the air pressure signal lamp switch is improved.
Description
Technical field
The present invention relates to the auto parts machinery field, be specially a kind of air pressure signal lamp switch.
Background technology
During running, need the air pressure of automobile gas circuit braking system be detected in real time, and the form with acousto-optic is reported to the police when air pressure reaches set point.The air pressure signal lamp switch is a kind of of baroswitch, and its effect is that Continuity signal circuit for lamp realization signal lamp is lighted when air pressure reaches set point.The air pressure signal lamp switch is reported to the police in the prior art has time-delay, and sensitivity is relatively poor, and is prone to because air-tightness causes switch failure inadequately.
Summary of the invention
The object of the invention provides a kind of air pressure signal lamp switch, to solve prior art air pressure signal lamp poor sensitivity, is prone to the problem that lost efficacy.
In order to achieve the above object, the technical scheme that the present invention adopted is:
The air pressure signal lamp switch comprises the Switch main body with inner chamber, it is characterized in that: be provided with the briquetting with inner chamber in the said Switch main body inner chamber; In the Switch main body inner chamber of briquetting top the electrode tip holder with inner chamber is installed; And be provided with packing ring between briquetting and the electrode tip holder, two L type electrodes are installed in the said electrode tip holder inner chamber, two electrode horizontal ends connect altogether in electrode tip holder and are one; Two electrodes vertically end are slidingly mounted in the electrode tip holder and the vertical end of electrode passes electrode tip holder respectively; Folder cloth diaphragm is installed in the Switch main body inner chamber of briquetting below, is slidingly fitted with jacking block in the said briquetting, said jacking block lower end is shaped to cambered surface; And the jacking block lower end passes briquetting and replaces on folder cloth diaphragm; Said jacking block upper end is stretched in the electrode tip holder to connect altogether with two electrode horizontal ends and is one, is arranged in Switch main body inner chamber bottom accent and is equipped with to cooperate with the Switch main body sidewall and constitutes the sealing ring that seals, and said sealing ring center has the cavity of coupling cock chamber body.
Described air pressure signal lamp switch; It is characterized in that: said electrode tip holder top is provided with deep trouth, and jacking block upper end, two electrode horizontal ends joints are provided with resetting block, are provided with spring in the said deep trouth; Said spring lower end is fixed on the resetting block, and the spring upper end is fixed on deep trouth bottom land place.
Described air pressure signal lamp switch is characterized in that: said jacking block outer wall forms annular table, and is connected with a plurality of springs between the annular table of jacking block and the packing ring.
The present invention is simple in structure, is easy to realize, electrode tip holder, jacking block sealing ring cooperate the formation sealing with Switch main body, has improved the air-tightness of air pressure signal lamp switch; Cavity through sealing ring is introduced air pressure signal, makes folder cloth diaphragm receive the gas pressure effect and drives jacking block and move, and then drive the electrode action and can light signal lamp rapidly; Electrode resets through the spring in the electrode tip holder deep trouth, and jacking block resets through the spring between jacking block annular boss and the packing ring, can realize automatically reseting of air pressure signal lamp switch; The effect of insulation is also played in the setting of packing ring, has improved the fail safe of air pressure signal lamp switch.
