The pressure gauge (1) is connected in seal to an air input nozzle via an airway (2). The utility model is characterized in that: the air intake nozzle comprises a taper body (3); a through hole is arranged in the axial direction of the taper body (3); the airway (2) is connected in seal to the bottom surface of the taper body (3) via the through hole; partial of the taper body (3) in the utility model is inserted with a spark plug hole of the cylinder, so as to measure the cylinder pressure. Because a propping rod (4) inside the air intake nozzle can prop up a thimble on the tyre, the utility model can be adopted to detect the pressure of tyre or cylinder. Besides, with excellent portability, the utility model can be applied for the repair and daily maintenance of motor vehicles.
Description
Technical field
The utility model relates to a kind of pressure-detecting device, and especially a kind of tire, cylinder are used pressure-detecting device more.
Background technology
Tire and cylinder pressure pick-up unit are widely used in the maintenance and the operational maintenance of motor vehicles, at any time detect tire and cylinder pressure etc., as Chinese patent CN2455502Y " the portable type tire pressure detects and the supplemental inflatable device ", CN2380418Y " tire pressure gauge ", and the cylinder pressure pick-up unit is mainly used in measuring machine motor vehicle inner cylinder pressure, discloses a kind of cylinder pressure pick-up unit very easily that uses and carry all as Chinese patent CN2160896Y " cylinder pressure pick-up unit ".
Tire and cylinder pressure value are motor vehicles maintenance and the required significant data of operational maintenance, measure above-mentioned two kinds of pressure at present and must adopt several different devices, but its measuring principle is identical, have caused the inconvenience of using.
Summary of the invention
For addressing the above problem, but the utility model proposes a kind of not only measure tire pressure but also can measure the cylinder pressure tires, cylinder is used pressure-detecting device more.
A kind of tire, cylinder is used pressure-detecting device more, comprise tensimeter, this tensimeter is tightly connected by wireway and admission piece, its special feature is, admission piece comprises a cone, on this cone is axial, have a through hole, wireway is tightly connected by this through hole and pyramidal bottom surface, being equipped with one in pyramidal through hole can be along the push rod of this through hole slip, one section of this push rod for solid and stretch out outside the through hole, the remainder of this push rod is a hollow tubular, have at least one air admission hole on it, one spring is arranged between wireway and push rod in through hole, and an end of this spring is connected with push rod, and the other end is connected with wireway or cone inside surface.
The admission piece of this device is inserted the spark-plug hole of cylinder, can measure cylinder pressure, because push rod can back down the thimble of tire, therefore also can be used for measure tire pressure, adopt the utility model can detect tire or cylinder pressure, and easy to carry, be fit to the maintenance of motor vehicles and the usefulness of operational maintenance, can also be in operation and check that at any time tire and cylinder work quality and cylinder pad wash out, judge the cylinder barrel method plug ring degree of wear etc.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the structural representation of embodiment one admission piece part in the utility model;
Accompanying drawing 3 is the structural representation of embodiment two admission pieces part in the utility model.
Embodiment
Come the utility model is described in further detail below in conjunction with accompanying drawing.
Example one:
As shown in Figure 1, the utility model is made of tensimeter 1, wireway 2 and admission piece, adopts O-ring seal to be connected and sealed between wireway 2 and tensimeter 1, the admission piece, to avoid producing measuring error because of gas leakage.
As shown in Figure 2, admission piece mainly comprises a cone 3, have a through hole along axis direction in this cone 3, wireway 2 is inserted in the through hole, be tightly connected with the bottom surface of cone 3, one push rod 4 is installed in the through hole of cone 3, this push rod 4 can slide in through hole, one section of this push rod 4 is solid, stretch out outside through hole, the remainder of this push rod 4 is a hollow tubular, is positioned at through hole substantially, on this part, have air admission hole 5, drive pore 5 places into and be positioned at outside the through hole, spring 6 also is installed in the through hole of cone 3, between 6 on this spring and wireway 2 and the push rod 4, one end of this spring 6 is connected with push rod 4 afterbodys, and the other end is connected with wireway 2 or cone 3 inside surfaces.
Can leave the gap between push rod 4 and the cone 3, on the one hand be convenient to processing and manufacturing, though on the other hand on the push rod 4 drive into pore 5 places be positioned at through hole can the block airflow passage yet.
For being convenient for measuring, whole wireway 2 has at least one section to adopt flexible pipe, plays universal effect, can certainly adopt one whole flexible pipe.
Because temperature is higher and oil stain is arranged in the cylinder, so cone 3 parts should adopt rubber or plastics, especially oil resistant rubber or heat resistant rubber material.
During practical set, spring 6 stretches out outside the through hole push rod 4, air admission hole 5 on the push rod 4 is also outside through hole, all the time be in communication with the outside, when needs were measured cylinder pressure, with the spark-plug hole that cone 3 is aimed at cylinder, hollow space, wireway 2 that gas can pass through air admission hole 5, push rod 4 successively entered tensimeter 1, perhaps, from tensimeter 1, can directly read the cylinder pressure value directly from the gap process of push rod 4 with cone 3.
When needing measure tire pressure, cone 3 is aimed at the valve of tire, push rod 4 natures can back down the thimble in the cranked tire valve, though push rod 4 slightly shrinks, but the air admission hole 5 on the push rod 4 still is connected with the external world at this moment, gas in the tire enters tensimeter through air admission hole 5, the hollow space of push rod 4, wireway 2 equally successively, even air admission hole 5 is headed in the vertebra shape body 3, gas still can directly read tire pressure value directly from the gap process of push rod 4 with cone 3 from tensimeter 1.
Example two:
As shown in Figure 3, be with a housing 7 outside push rod 4, fixing casing respectively has an annular boss at housing 7 inside surfaces and push rod 4 outside surfaces in vertebra shape body 3, be set with spring 8 on the push rod between two annular boss 4.
Can leave the gap between push rod 4 and the housing 7, promptly can be used as the passage of gas flow, also be convenient to processing and manufacturing, the gap of push rod 4 and cone 3 acts on identical among its effect and the embodiment one.
Remainder is identical with embodiment one.
