Description

Multifunction air-extracting and -inflation pump

The utility model belong to bleed, inflator is made the field.

Prior art in the utility model prior art field is: in the market single function of Chu Shouing bleed, inflator, the deficiency of existence be take a lot of work, time-consuming, inefficiency.

Purpose of design of the present utility model is: at the deficiency of above-mentioned existence, design and a kind ofly can bleed, inflate, again fixedly body and jack-up weight multi-functional bleed, inflator.

Design proposal of the present utility model is: multi-functional bleeding, inflator is made up of on a body three parts, first portion 30 is shaped on air chamber in the front portion of body 29, piston 3 adopts nut 4 to be fixed on the piston rod 25, compression ring 24 is housed on the piston, during work owing to affect arm 1 to pump, make piston move along air chamber, air chamber cover (2,27) adopt upper end portion and the underpart of screw respectively at air chamber, and in the hole of air chamber cover, be embedded with seal ring 26, force air in air chamber, to cause the pressure of bleeding and supplying gas, make air enter second portion 32 by the air flue in the body 29.Cushion block 11 in the second portion, air dividing plate 12, the valve cage 13 and the plate 14 of supplying gas together adopt the rear portion that is bolted to body, and spring 15 and valve block 16 are housed in valve cage 13, when making pistons work, because the effect of bleeding and calming the anger, force valve block opening and closing respectively, thereby reach the purpose of bleeding and inflating, gas is chewed 17 and is positioned on the plate 14 of supplying gas and is communicated with air flue, one end of the band of gas 18 is chewed with the gas on the plate of supplying gas and is connected, the other end then with the gas storage chamber 23 that is positioned at underpart on gas chew and be connected, its main effect is to send into the air that extrudes in the gas storage chamber again, after the air of air pressure inequality mixes again when making work, chew 21 from exhaust and send, simultaneously gas storage chamber also has airborne moisture content is condensed in the interior effect of gas storage chamber, and gas storage chamber is then chewed 21 with exhaust and is connected.The bottom of gas storage chamber is to adopt mobilizable base plate 22 sealings, and its main effect is: seal and discharge water.Third part 31 is to be shaped on a jack at the middle part of body 29, is used for fixing body and jack-up weight.The top 7 of jack is positioned at the upper end of push rod 10, it mainly acts on and makes push rod and by head part good the contact can be arranged, 19 lower ends that are positioned at push rod of positioning plate, it just can not be again to rising after mainly acting on and making push rod be raised to certain height, play the security insurance effect, push rod is positioned at body, ratchet nut 8 adopts screw thread to be connected with push rod, and that ratchet nut is embedded in the body is spacing with screw, makes ratchet nut freely to rotate in the hole, and ratchet 9 is meshed with ratchet nut, thereby rotation ratchet, will make ratchet nut rotation, and it is up and down to drive push rod, reaches the fixedly purpose of body and jack-up weight.

The utility model compared with prior art has compact structure, bleed, inflation, jack simultaneously and the characteristics of depositing, having overcome jack and air pump in the present work can not the while and deposit the deficiency of application, thus save time, saving of labor, high working efficiency.

Embodiment:

Fig. 1 be multi-functionally bleed, a kind of embodiment of inflator.

Multi-functionally bleed, the enforcement of inflator: in conjunction with the accompanying drawings 1 and specification the 5th part, the body 29 and by existing machining technique processing body and other parts in addition of at first casting carries out Installation and Debugging and gets final product by shown in Figure 1 then.

Claims (2)

1, a kind ofly multi-functionally bleed, inflator, it is characterized in that:

A, front portion at body 29 is shaped on air chamber, piston 3 adopts nut 4 to be fixed on the piston rod 25, compression ring 24 is housed on the piston, during work owing to affect arm 1 to pump, make piston move along air chamber, air chamber cover (2,27) adopt upper end portion and the underpart of screw respectively at air chamber, and in the hole of air chamber cover, be embedded with seal ring 26, force air in air chamber, to cause the pressure of bleeding and supplying gas, and cushion block 11, air dividing plate 12, the valve cage 13 and the plate 14 of supplying gas together adopt the rear portion that is bolted to body, and spring 15 and valve block 16 are housed, when making pistons work, in valve cage 13 because the effect of bleeding and calming the anger, force valve block opening and closing respectively, thereby reach the purpose of bleeding and inflating, gas is chewed 17 and is positioned on the plate 14 of supplying gas and is communicated with air flue, and an end of the band of gas 18 is chewed with the gas on the plate of supplying gas and is connected, the other end then with the gas storage chamber 23 that is positioned at underpart on gas chew and be connected, gas storage chamber is then chewed 21 with exhaust and is connected;

B, a jack is arranged at the middle part of body 29, the top 7 of jack is positioned at the upper end of push rod 10,19 lower ends that are positioned at push rod of positioning plate, and push rod is positioned at body, ratchet nut 8 adopts screw thread to be connected with push rod, and that ratchet nut is embedded in the body is spacing with screw, makes ratchet nut freely to rotate in the hole, and ratchet 9 is meshed with ratchet nut, thereby rotation ratchet, will make ratchet nut rotate, and it is up and down to drive push rod, thereby has realized the purpose of jack.

2, according to claim 1ly multi-functionally bleed, inflator, it is characterized in that: mobilizable base plate 22 sealings are adopted in the bottom of gas storage chamber 23.
