Description
Technical field
This utility model belongs to inflator level pressure auxiliary accessories technical field, is specifically related to a kind of independent constant pressure arrangement.
Background technology
Current inflator structure is relatively simple, and function is more single.In daily life, people often inflate to the ordinary articles such as tire, sport ball with inflator, but need during inflating repeatedly to press sensed pressure with hands, to ensure that air pressure is normal.But owing to Manual press exists the problems such as air pressure perception is inaccurate, regular service conditions cannot be met so that be inflated object or do not reach ideal effect.For overcoming drawbacks described above, it is necessary to design a kind of independent constant pressure arrangement.
Summary of the invention
This utility model solves the technical problem that and there is provided a kind of independent constant pressure arrangement that can automatically judge and conveniently dismantle, this device can be added to family and commonly use on inflator, thus realize the standard pressure of the ordinary articles such as bicycle tyre, basketball, football is inflated, and have cheap, the advantage such as be readily disassembled.
This utility model adopts the following technical scheme that for solving above-mentioned technical problem, a kind of independent constant pressure arrangement, including sealing cavity, it is arranged at and seals the piston of inside cavity and be arranged at the air pressure regulator sealing cavity top, the bottom wherein sealing cavity is provided with and seals the gas outlet that cavity communicates, connect on this gas outlet and have single direction inflating valve, the bottom sealing cavity is provided with and seals the air inlet that cavity communicates, this air inlet is connected with inflator by single direction inflating valve, the middle part sealing cavity is provided with and seals the pressure-reduction outlet that cavity communicates, air pressure regulator is sealed by the accurate thread on screw rod and is bolted in the top sealing cavity, the bottom of screw rod is fixed on by spring in the top of piston.
Further preferably, the screw rod of described air pressure regulator is from top to bottom sequentially provided with datum line, football datum line, basketball datum line, vollyball datum line, tire datum line and end line.
Further preferably, described pressure-reduction outlet connects has gas to blow a whistle.
Further preferably, described single direction inflating valve is American Air inflating valve.
Major function of the present utility model is: set corresponding datum line on air pressure regulator, this device is arranged on inflator, when inflating to object, gas in inflator enters inlet chamber by air inlet, enter the part of the gas in inlet chamber to be directly entered through gas outlet (or through ball pin) and inflated object, another part compression piston, when by inflated interior of articles air pressure reach set air pressure time, piston is just compressed to pressure-reduction outlet and turns on inlet chamber, gas in inlet chamber is discharged through pressure-reduction outlet, entrance gas is blown a whistle, this seasonal epidemic pathogens is blown a whistle to send and is piped, prompting inflate people stop inflate, inflate and can pull up this device after terminating, it is the most convenient to use.
It is simple that this utility model compared with prior art has the advantages that (1) uses, and practicality is wider；(2) convenient dismounting, easy to use；(3) using level pressure, degree of accuracy is high.

Detailed description of the invention
Particular content of the present utility model is described in detail in conjunction with accompanying drawing.A kind of independent constant pressure arrangement, including sealing cavity 7, it is arranged at the piston 4 sealed within cavity 7 and is arranged at the air pressure regulator 1 sealing cavity 7 top, the bottom wherein sealing cavity 7 is provided with and seals the gas outlet 10 that cavity 7 communicates, connect on this gas outlet 10 and have single direction inflating valve 6, the bottom sealing cavity 7 is provided with and seals the air inlet 5 that cavity 7 communicates, this air inlet 5 is connected with inflator by single direction inflating valve 6, the middle part sealing cavity 7 is provided with and seals the pressure-reduction outlet 8 that cavity 7 communicates, air pressure regulator 1 is sealed by the accurate thread on screw rod 2 and is bolted in the top sealing cavity 7, the bottom of screw rod 2 is fixed on by spring 3 in the top of piston 4.Datum line 101, football datum line 102, basketball datum line 103, vollyball datum line 104, tire datum line 105 and end line 106 from top to bottom it is sequentially provided with on the screw rod 2 of described air pressure regulator 1, for different inflated articles, conveniently air pressure regulator 1 is regulated to corresponding datum line.Connecting on described pressure-reduction outlet 8 has gas to blow a whistle, and when reaching the pressure reference set in advance, the outside aerofluxus of inlet chamber 9 is blown a whistle by gas and sent sound as prompting.Described single direction inflating valve 6 is American Air inflating valve, for ensureing the sealing of inlet chamber 9.
Operation principle of the present utility model is: first against different inflatable objects, setting corresponding datum line on air pressure regulator, now piston prevents the conducting of pressure-reduction outlet and inlet chamber；nullThen this device is arranged on inflator (inflator gas outlet is connected with this device air inlet)，This device gas outlet and object of being inflated connect (or through ball pin and object conducting of being inflated)，When inflating to object，Gas in inflator enters inlet chamber by air inlet，Enter the gas part of inlet chamber to be directly entered through gas outlet (or through ball pin) and inflated object，Another part gas compression piston，Piston compression spring，Along with the carrying out inflated，Gas in inlet chamber is more and more severe to the compression of piston，When by inflated interior of articles air pressure reach set air pressure time，Piston is just compressed to pressure-reduction outlet and turns on inlet chamber，Gas in inlet chamber is discharged through pressure-reduction outlet，Entrance gas is blown a whistle，Blow a whistle can send under the situation having gas to enter due to gas and pipe，Thus can remind inflate people stop inflate，End of inflating can pull up this device.
Of the present utility model ultimate principle has more than been shown and described; principal character and advantage; on the premise of without departing from this utility model spirit and scope, this utility model also has various changes and modifications, and these changes and improvements both fall within claimed scope of the present utility model.
