Abstract
The utility model relates to an air compressor, in particular to an air compressor with mechanically adjustable output air pressure, which mainly comprises a shell, a motor, a cylinder and a piston. The cylinder head of the cylinder is connected with an air inflation pipe and a pressure gauge and is also connected with a pressure regulating valve, and a regulating knob of the pressure regulating valve protrudes out of the shell to facilitate regulation. Moreover, the regulating knob of the pressure regulating valve is arranged on the side face or the top surface of the shell. The utility model has the advantages that: a user can select the mechanical pressure regulating valve with a higher performance-price ratio instead of a high-cost electronic pressure sensing control type air compressor according to differences of objects to be inflated, so as to adjust the output air pressure and meet the requirements for use of various objects to be inflated.
Description
Technical field
The utility model relates to a kind of air compressor, is meant a kind of air compressor of mechanical type can regulate output pressure especially.
Background technique
Air compressor is the abbreviation of air compressor, is meant by the motor driven piston reciprocating to produce the machine of superheated steam in cylinder especially.The existing technology of air compressor is shown in Fig. 1 to 2; Mainly comprise shell 1, motor 2, cylinder 3, piston 4 and pressure relief safety valve 8; Motor 2 driven plunger 4 are reciprocating discharge with suction, compression and the superheated steam of accomplishing gas in cylinder 3, is connected with pressure gauge 6 and air-inflating tube 5 on the cylinder head 31 of said cylinder 3; Pressure relief safety valve 8 is constant factory setting value, only does to exceed the pressure release Safety function of maximum set pressure, and can't let the user regulate voluntarily.During concrete work, open switch 11, motor 2 is through the transmission of gear, bent axle and connecting rod; Make piston 4 reciprocating in cylinder 3; The gas of pressurization is delivered to the object to be inflatable body through air-inflating tube 5 after discharging from cylinder head 31, and pressure gauge 6 demonstrates the air pressure of output; When output pressure exceeded the factory setting value, 8 pairs of output pressures of pressure relief safety valve carried out pressure release.In sum; The existing technology of air compressor can't adopt the mode of mechanical structure to regulate to its output pressure; Default Value such as this air compressor is the special-purpose air compressor of automobile tire; Then can't inflate bicycle tyre or kayak, can be if use then because of the factory setting value is lower than the inflation object, causing inflating object can't gassy; Perhaps because of the factory setting value is higher than the inflation object, and cause inflating danger and the hidden danger that there is explosion in object.Therefore, existing technology can not realize a tractor serves several purposes of air compressor, though and the air compressor can regulate delivery pressure value of electron pressure induction control, cost is more high than traditional mechanical air compressor, in actual life, brings inconvenience to the user.
The inventor of the utility model utilizes its professional eye and professional knowledge because the structure disappearance and the inconvenience of above-mentioned convention air compressor are being adhered to the spirit that research is innovated, kept on improving, and works out a kind of air compressor of mechanical type can regulate output pressure.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of existing technology, and provides a kind of portable, the air compressor of mechanical type can regulate output pressure.
The utility model is realized through following technological scheme; Mainly comprise housing, motor, cylinder and piston, be connected with air-inflating tube and pressure gauge on the cylinder head of said cylinder, also connect a pressure regulator valve on the said cylinder head; The adjusting knob projection of said pressure regulator valve is conveniently regulated in outside.
The adjusting knob of said pressure regulator valve is arranged on the side of housing.
The adjusting knob of said pressure regulator valve is arranged on the end face of housing.
The advantage of the utility model is; The user can be according to the difference of required inflation object; And can not select the high electron pressure induction control air compressor of cost for use; And come to be provided with voluntarily the output pressure of different sizes, thereby satisfy usage requirement to the object of various inflations with the higher mechanical type pressure regulator valve of cost performance.

Fig. 3 is one of schematic appearance of the utility model;
Fig. 4 is one of internal structure schematic representation of the utility model.
Fig. 5 be the utility model schematic appearance two;
Fig. 6 be the utility model the internal structure schematic representation two.
Embodiment
It is a kind of portable that the utility model has been proposed confession; The air compressor of mechanical type can regulate output pressure is described further below in conjunction with the preferred embodiment of 3 to 4 pairs of the utility model of accompanying drawing, and the utility model mainly comprises housing 1, motor 2, cylinder 3 and piston 4; Be connected with air-inflating tube 5 and pressure gauge 6 on the cylinder head 31 of said cylinder 3; Also connect a pressure regulator valve 7 on the said cylinder head 31, adjusting knob 71 projections of said pressure regulator valve 7 are conveniently regulated in housing 1 outside.The adjusting knob 71 of said pressure regulator valve 7 is arranged on the side of housing 1.
Before the inflation, the user can through rotation adjusting knob 71, be provided with the output pressure of pressure regulator valve 7 according to the specified air pressure of object to be inflatable body, thereby sets up the size of air compressor output pressure on their own.In the operation engineering, open switch 11, motor 2 is through the transmission of gear, bent axle and connecting rod; Make piston 4 reciprocating in cylinder 3; The gas of pressurization is delivered to the object to be inflatable body through air-inflating tube 5 after discharging from cylinder head 31, and pressure gauge 6 demonstrates the air pressure of output.Because the adjustable pressure scope of pressure regulator valve 7 still is set in a certain safety range; Delivery pressure after the adjusting can not surpass the specified upper limit of object to be inflatable body; Therefore the user can be according to the difference of required inflation object; And can not select the air compressor of the high electron pressure induction control of cost for use, and come to be provided with voluntarily the output pressure of different sizes with the higher mechanical type pressure regulator valve of cost performance, thus satisfy usage requirement to the object of various inflations.
The above embodiment has only expressed a kind of mode of execution of the utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.The adjusting knob 71 of for example said pressure regulator valve 7 also can be arranged on the end face of housing 1, referring to accompanying drawing 5,6.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.Therefore, the protection domain of the utility model patent should be as the criterion with accompanying claims.
