Abstract
The utility model relates to an alarm capable of detecting engine oil pressure and sending out alarm signals. The alarm comprises an integral shell body shaped like a circular truncated cone, and a connecting inserting piece, a telescopic structure and an oil pressure chamber are sequentially arranged inside the shell body from top to bottom. The telescopic structure comprises a spring and a cylindrical contact point arranged inside the spring. An insulation boss is arranged in the cylindrical contact point, the top of the insulation boss penetrates through the cylindrical contact point, and the bottom of the insulation boss contacts with a membrane. The bottom of the insulation boss is connected with a contact disc, and when the insulation boss ascends or descends, the contact disc contacts with or breaks away from the cylindrical contact point. The bottom of the membrane contacts with the top of the oil pressure chamber, and the oil pressure chamber is provided with an oil inlet pipe. The telescopic structure is located in a sealed cavity isolated from the oil pressure chamber, an exhaust hole is arranged in the sealed cavity, and a seal ring is arranged between the sealed cavity and the oil pressure chamber. According to the engine oil pressure alarm, the seal ring is arranged between the sealed cavity and the oil pressure chamber, sealing performance is improved, and measuring precision is therefore improved.
Description
Technical field
The utility model relate to a kind of can the detecting engine engine oil pressure, and send the alarm of alarm signal.
Background technique
When the engine oil pressure of motor was in the improper scope, engine oil pressure alarm sent alarm signal.Engine oil pressure alarm of the prior art mainly exists defective to be, the extending means in the alarm is prone to movable the inefficacy, thereby causes sending alarm signal, so that security incident occurs after moving through the long period.Simultaneously, poor sealing performance between extending means chamber of living in and the oil pressure chamber, easily leakage of oil, thus cause detection accuracy to reduce even inefficacy.
The model utility content
In order to solve the technical problem that exists in the prior art, the purpose of this utility model is to provide a kind of engine oil pressure alarm of simple in structure, function admirable.
The technical solution adopted in the utility model is as follows:
Engine oil pressure alarm is characterized in that, comprises the integral housing that is round table-like,
Under upper, be provided with successively connection inserted sheet, shrinking structure and oil pressure chamber in the housing;
Shrinking structure comprises spring, places the cylindrical contact of spring inner;
Be provided with the insulation boss in the cylindrical contact, cylindrical contact is passed at insulation boss top, and insulation boss bottom contacts with diaphragm;
Insulation boss bottom is connected with contact disc, and when the insulation boss rose or descends, contact disc contacted with cylindrical contact or breaks away from;
The bottom of diaphragm contacts with the top of oil pressure chamber, and the oil pressure chamber is provided with oil inlet pipe;
Extending means is in the airtight cavity that completely cuts off with the oil pressure chamber, and described airtight cavity is provided with exhaust port, is provided with seal ring between described airtight cavity and the oil pressure chamber.
Comparatively perfect is that the outside of described housing is provided with several annular grooves.
The utility model engine oil pressure alarm has following advantage:
1, be specially designed the spring shrinking structure, by the jacking of oil pressure chamber or whereabouts, drive the insulation boss and rise or descend, thereby contact disc is contacted with cylindrical contact or break away from, thereby the generation alarm signal provides warning message in instrument panel.
2, between airtight cavity and oil pressure chamber, be provided with seal ring, with the raising sealing, thereby measuring accuracy be improved.
3, structural design is simple, cheap, and adaptability is wider.
Description of drawings
For the ease of it will be appreciated by those skilled in the art that below in conjunction with accompanying drawing model utility is further described.
Fig. 1 is structural representation of the present utility model.
Embodiment
See also Fig. 1, engine oil pressure alarm comprises the integral housing 8 that is round table-like, is provided with successively under upper in the housing 8 to connect inserted sheet 5(and be connected transmission of signal usefulness with electrical equipment), shrinking structure and oil pressure chamber.
Shrinking structure comprises spring 10, places the cylindrical contact 2 of spring 10 inside.
Be provided with insulation boss 9 in the cylindrical contact 2, cylindrical contact 2 is passed at insulation boss 9 tops, and insulation boss 9 bottoms contact with diaphragm 6.
Insulation boss 9 bottoms are connected with contact disc 4, and when insulation boss 9 rose or descends, contact disc 4 contacted with cylindrical contact 2 or breaks away from.
The bottom of diaphragm 6 contacts with the top of oil pressure chamber, and the oil pressure chamber is provided with oil inlet pipe 7.
Extending means is in the airtight cavity that completely cuts off with the oil pressure chamber, and this airtight cavity is provided with exhaust port 11, is provided with seal ring 3 between airtight cavity and the oil pressure chamber.
Simultaneously, the outside of housing 8 is provided with several annular grooves 1 that is used for installation.
Above content only is to the utility model structure example and explanation; under those skilled in the art described specific embodiment is made various modifications or replenish or adopt similar mode to substitute; only otherwise depart from the structure of model utility or surmount this scope as defined in the claims, all should belong to protection domain of the present utility model.
