Abstract
The utility model relates to a vehicle tire pump, mainly comprising an air reservoir 1, a piston, an O-shaped ring 3, an air container cap 4, a spring 5, a stressed plate 6, a piston pole 7, a pressure gauge 8, a connecting pipe 9, an O-shaped ring 10, a connecting nut 11, a sealing ring 12, a core axis 13, an air pipe 14, a valve pin 15, a valve 16, a valve base 17, a base 18 and a horse 19. The utility model is characterized in that the air reservoir 1 is provided with two cavities: one is cavity I and the other is cavity II, and the two cavities are communicated with each other; the upper part the cavity II of the air reservoir is connected with the air pipe 14 by a pressure three way device and the lower part is provided with a non return valve; the non return valve is arranged and sealed by the base cap 18. The utility model has the advantages of high work efficiency, small size, and convenient carrying, also can measure the pressure of tire mainly used for the pumping of bicycles, motorcycles and balls.
Description
One, technical field:
The utility model relates to a kind of inflating pump, in particular for tire and the ball tire inflating pump of inflating thereof to bicycle, motorcycle.
Two, background technique:
At present, the inflating pump majority of domestic production is the inflating pump of conventional structure, this inflating pump is mainly by gas cylinder, piston, piston rod, spring, tracheae, the foot-operated parts that wait are formed, because its structure is a bypass structure, do not design one-way valve, make each to bicycle, when the tire of motorcycle and ball inflating thereof, the gas flow that injects only is 2/5 of a gas cylinder volume, and the tire internal air pressure has much can not learning during gas injection, so working efficiency is very low when using this inflating pump, tire is exploded, simultaneously, the volume and weight of this inflating pump is bigger, is not easy to carry.
Three, summary of the invention:
The purpose of this utility model provides a kind of injection efficiency height, can measure the tire inflating pump of tire pressure.
Concrete scheme of the present utility model is: a kind of tire inflating pump, comprise gas cylinder, piston, " O " type circle, air storage cover, spring, stressed plate, piston rod, tracheae, foot rest, it is characterized in that: A, gas cylinder have two chambeies, I chamber and II chamber, and this two chamber communicates; The top in B, gas cylinder II chamber is communicated with tracheae by the pressure three-way device, and its bottom is provided with one-way valve, and this one-way valve is installed and sealing by bottom.
The advantage of concrete scheme of the present utility model is: (1), because the gas cylinder of tire inflating pump is provided with two chambeies, when inflating a tire, high working efficiency.(2), because of pressure gauge is installed, can measure tire pressure, thereby tire be exploded when avoiding inflating.(3), this equipment volume is little, light practicality is easy to carry.
Four, description of drawings:
Fig. 1 is a structural representation of the present utility model.
Five, embodiment:
As shown in Figure 1: the utility model mainly is made up of gas cylinder 1, piston 2, " O " type circle 3, air storage cover 4, spring 5, stressed plate 6, piston rod 7, pressure gauge 8, connecting tube 9, " O " type circle 10, attaching nut 11, seal ring 12, mandrel 13, tracheae 14, valve pin 15, valve 16, valve seat 17, base 18, foot rest 19, it is characterized in that: A, gas cylinder 1 have two chambeies, I chamber and II chamber, this two chamber communicates; The top in B, gas cylinder II chamber is communicated with tracheae 14 by the pressure three-way device, and its bottom is provided with one-way valve, and this one-way valve is installed and sealing by bottom 18.
Also can see from Fig. 1: the II chamber the gas cylinder 1 communicates with bottom, I chamber.
Also can find out from Fig. 1: the pressure three-way device is made up of pressure gauge 8, connecting tube 9, " O " type circle 10, attaching nut 11, seal ring 12, mandrel 13, wherein connecting tube 9 is three-way pipes, setting pressure table 8 is managed in going up of it, following pipe is installed on the II chamber of gas cylinder, and side pipe connects tracheae 14 by attaching nut 11; Be provided with mandrel 13 in connecting tube 9, mandrel 13 is equipped with " O " type circle 10 with the jointing place of pressure gauge 8 and connecting tube 9, and connecting tube 9 has seal ring 12 with the jointing place in the II chamber of gas cylinder.
From Fig. 1 further as can be known: one-way valve is made up of valve pin 15, valve 16, valve seat 17, and wherein valve 16 is installed in the valve seat 17 by valve pin 15, and the bottom of valve seat 17 is connected with bottom 18.
Working principle of the present utility model: piston 2 moves downward the gas in the gas cylinder I chamber is injected in the gas cylinder II chamber under external force, and because of the effect of one-way valve, gas cylinder II chamber forms hyperbaric chamber pressurized gas are transported in the tire by tracheae 14.Each spring 5 is compressed the back and eliminates the external force spring and release energy and make piston return to position before the compression to repeat next time and inflate, and rotates and measures tire pressure all the time along with the tire internal pressure strengthens pressure gauge 8 pointers.
