Description

Inflator

The utility model relates to a kind of pump.

Existing pump is made up of socket, handgrip, piston, piston pulling rod, base that outlet nozzle and soft air pipe be housed, is equipped with foot-operated on the base.On the inflator base that has gas holder is housed also.The shortcoming of its existence is, because piston pulling rod drives piston moves, pull bar must be pulled to the socket top when inflating in tube, and the greasy dirt on the pull bar is easy to rub on one's body the user, the clothing of making dirty.

The utility model is at the deficiencies in the prior art, proposed a kind of piston relative fixed, the sleeve novel pump with the handgrip motion.

Task of the present utility model is to realize like this, the utility model is a kind of pump, comprise riding on socket, handgrip, piston, the base that outlet nozzle and soft air pipe are housed and the base, base is fixed in the air-guide standpipe lower end, and be communicated with outlet nozzle, piston is fixed in the upper end of air-guide standpipe, and is provided with the vent that is communicated with air-guide standpipe, the socket that internal diameter and piston coincide and Open Side Down is enclosed within the air-guide standpipe periphery, and handle is fixed on the socket upper bottom portion.Like this, during use, mention socket with handle and back and forth inflate, pressurized air enters air-guide standpipe from the hole at piston center, enter tire from outlet nozzle through soft air pipe again.

Described pump, but the suction port of the air-guide standpipe of gas storage be equipped with can only air inlet one-way valve.Like this, air-guide standpipe just can doublely be made gas holder, has dwindled the volume of gas storage inflator.

Described pump, the nozzle of socket are provided with and protrude the outer, base with foot-operated between be equipped with to make and ride the torque spring that turns on the nature, foot-operated middle part is provided with the card that can block the socket outer, is provided with the pressure spring that is enclosed within the air-guide standpipe periphery between socket and the base.When not using inflator, socket is pressed onto the end, on the base ride under spring action on turn over, the card on foot-operated blocks the socket edge, when carrying, as long as catch handgrip, and base can not skid off.

Described pump, the non-tight insertion ring is equipped with in socket nozzle inboard, and the socket wall is provided with inlet hole.Can reduce noise, air inlet is smooth, and inlet hole also can doublely be done tank filler sleeve.

Described pump, the stage casing of handle is provided with hanging nose.Inflator is the time spent not, and soft air pipe is hung over or is clipped on the hanging nose.

The utility model compared with prior art owing to taked piston relative fixed, sleeve to move with handgrip, and the outside of sleeve keeps clean, so people's the clothing of can not making dirty is clarity when using; The double gas holder of doing of air-guide standpipe has dwindled the volume of gas storage inflator; Turn on riding under spring action, the card of riding blocks the socket edge, catch handgrip, and base can not skid off, and is easy to carry.

Fig. 1 looks schematic representation for structure of the present utility model.

Fig. 2 is the cross-sectional schematic of A-A face among Fig. 1.

Fig. 3 is the structure cross-sectional schematic of prior art gas storage inflator.

Fig. 3 is existing pump, and by socket 33, handgrip 31, piston 34, piston pulling rod 32, gas holder 38 and the base 35 of taking valve 39 and soft air pipe 40 out of are housed form, the suction port of gas holder 38 is equipped with one-way valve 37.Be equipped with foot-operated 36 on the base 35.

Fig. 1, Fig. 2, Fig. 3 are an embodiment of the present utility model.Be a kind of air storing type pump, comprise foot-operated 4 on socket 3, handgrip 1, piston 16, the base 9 that outlet nozzle 13 and soft air pipe 12 are housed and the base 9, base 9 is fixed in air-guide standpipe 15 lower ends, and be communicated with outlet nozzle 13, piston 16 is fixed in the upper end of air-guide standpipe 15, and be provided with the vent that is communicated with air-guide standpipe 15, and internal diameter and the socket 3 that piston 16 coincide and Open Side Down are enclosed within air-guide standpipe 15 peripheries, and handle 1 is fixed on socket 3 upper bottom portion.But the suction port of the air-guide standpipe 15 of gas storage be equipped with can only air inlet one-way valve 11.The nozzle of socket 3 is provided with and protrudes outer 6, is equipped with between the base 9 and foot-operated 4 to make the torque spring 8 that turns on foot-operated 4 natures, and foot-operated 4 middle parts are provided with the card 5 that can block socket outer 6, are provided with the pressure spring 7 that is enclosed within air-guide standpipe 15 peripheries between socket 3 and the base 9.Non-tight plastic filler circle 14 is equipped with in socket 3 nozzle inboards, and socket 3 walls are provided with inlet hole 10.The stage casing of handle 1 is provided with hanging nose 2.Like this, during use, air inlet is smooth, mentions socket with handle and back and forth inflates, and pressurized air enters air pipe from the hole at piston center, enter tire by outlet nozzle through soft air pipe again; Air pipe just can doublely be made gas holder, and volume is less than original gas storage inflator.When not using inflator, socket is pressed onto the end, on the base ride under spring action on turn over, the card on foot-operated blocks the socket edge, when carrying, as long as catch handgrip, and base can not skid off.Inflator is the time spent not, and soft air pipe is hung over or is clipped on the hanging nose.
