Abstract
The utility model relates to a man-power pump for inflating and suction, which comprises that a middle cylinder 15 is provided with an exhaust valve 8; preliminary pressure cylinders 14, 16 are respectively arranged on both sides of the middle cylinder 15; piston rods 3, 4 are arranged in the preliminary pressure cylinders 14, 16, wherein, one end of each of the piston rods 3, 4 is respectively provided with pistons 5, 11, and the other end is respectively connected with both ends of a pressure plate 1; the middle of the pressure plate 1 is connected with a support frame 17; the support frame 17 is arranged on the middle cylinder 15; the preliminary pressure cylinders 14, 16 are respectively provided with air intake valves 5, 10 and exhaust valves 7, 9 communicated with the middle cylinder 15. The utility model has the advantages of continuous inflating and suction, high efficiency of inflating and suction, etc.
Description
The utility model relates to that a kind of manpower is taken out, inflator, especially for to the inflation of tire, air cushion etc. with to bleeding such as the bag storage of varicosity things such as silk, cotton, eider down and air film etc.
Conventional pump not only acts on dullness, and can not reach continuous charge, only push the time give tyre inflation, only play the air inlet effect when mentioning operation handlebar, can not inflate, thereby in whole gas replenishment process, exist the gap and stop filling phenomenon, thus charging efficiency low, waste time and energy.
The purpose of this utility model be to provide a kind of can continuous charge, can bleed and take out, fill that the high manpower of efficient is taken out, inflator again.
The purpose of this utility model is achieved like this: a kind of manpower is taken out, inflator, it comprises a middle part cylinder 15 that has outlet valve 8, be separately positioned on the first cylinder pressure 14,16 of cylinder 15 both sides, middle part, the piston rod 3,4 that in first cylinder pressure 14,16, is provided with, one end of piston rod 3,4 is equipped with piston 5,11, the other end is connected with the two ends of pressing plate 1 respectively, the middle part of pressing plate 1 is connected with support 17, support 17 is contained on the cylinder 15 of middle part, the outlet valve 7,9 that suction valve 6,10 is respectively arranged and communicate with middle part cylinder 15 on first cylinder pressure 14,16.
Below in conjunction with accompanying drawing the utility model is further described below.
Accompanying drawing is a structural drawing of the present utility model.
Piston 5,11 of the present utility model is provided with elasticity.Piston 5,11 adopts metallic material to make, be fixed on the end of piston rod 3,4 one ends, around piston 5,11, cover whippy material, as leather, plastics, nylon etc., also can add the cover elastic expansion ring, as the rubber circle, so that make the outer wall of piston 5,11 and the inwall driving fit of cylinder pressure 14,16 just, unlikely gas leakage.The other end of piston rod 3,4 stretches out cylinder pressure 14,16 just, respectively is shaped on plush copper 21,22 on it, is provided with pin-and-hole on plush copper 21,22.Arch is made at the middle part of pressing plate 1, rotatingshaft 2 is inserted in perforate on it in hole, be located at by the two ends with rotatingshaft 2 in the axis hole of support 17 upper ends, be connected with the active of support 17 thereby reach the middle part that makes panel 1, the upper-end surface of the lower end of support 17 and middle part cylinder 15 fixes; Be shaped on projection 18,19 at the two ends of pressing plate 1, have on it with plush copper 21,22 on the pin-and-hole that matches of hole, by pin plush copper 21,22 is connected with projection 18,19 respectively, thereby the other end that reaches piston rod 3,4 is connected with the two ends of pressing plate 1, when the A that presses dynamic pressure plate 1, B two ends, piston rod 3,4 just can move up and down freely, thereby has guaranteed that piston rod 3,4 drives piston 5,11 and moves up and down.
The utility model is divided into intermediate pressure cylinder 23 and high-pressure cylinder 20 by dividing plate 24, be provided with outlet valve 8 at intermediate pressure cylinder 23 tops, also be provided with outlet valve 25 at high-pressure cylinder 20 tops, when not needing pressure too big, dismountable outlet valve 25 is as vent, and gas tube is connected on the outlet valve 8, can directly externally inflate, when the pressure of needs inflations was big, gas tube was connected on the outlet valve 25.
The upper end portion of cylinder pressure 14,16 just of the present utility model is provided with vent 12,13 respectively.When piston rod 3,4 is done upper and lower to-and-fro motion, guarantee the air pressure balance that piston 5,11 is suffered by vent 12,13.
When manpower adopted foot-operated or hand to press A end by press table 1, piston rod 3 drove pistons 5 and moves down, and this moment, suction valve 6 was closed, and the gas in the first cylinder pressure 14 bottom cylinders is compressed, cylinder 15 inflations of 7 pairs of middle parts of outlet valve; Meanwhile, the piston rod 4 of the other end drives piston 11 and up moves, and makes just and causes negative pressure in the cylinder pressure 16 bottom cylinders, and outlet valve 9 is closed, and suction valve 10 is opened, and extraneous air-flow is entered in the first cylinder pressure 16 by suction valve 10.When pressing the B end of press table 1 again, piston rod 4 drives piston 11 and moves downward, this moment, suction valve 10 cut out, outlet valve 9 is opened, air-flow enters in the cylinder 15 of middle part from outlet valve 9, externally inflated by outlet valve 8, and the piston rod 3 drive pistons 5 of the other end moves upward, outlet valve 7 is closed, just cause negative pressure in the cylinder pressure 14, suction valve 6 is opened, and air-flow enters in the first cylinder pressure 14 from the external world, A is pressed in circulation and so forth, the B end, when the needs inflation pressure was big, when the pressure in the intermediate pressure cylinder 23 arrived to a certain degree, outlet valve 8 was opened, be inflated to high-pressure cylinder 20, thereby finish the continuous charge action.In the time will bleeding to the varicosity thing of the silk of bag storage, eider down, cotton fabric and so on, as long as will be linked to the other end of the connecting tube on the suction valve 6,10 fills in the bag, air in the bag can be taken out, thereby can make the varicosity thing that is loaded in the bag be in the compression stored condition, after adding moth-proof and mould-proof change medicine, can play the effect that moth-proof and mould-proof becomes.In addition air film is vacuumized effects such as can reaching cold storing and fresh-keeping.
The efficient height is taken out, filled to the utility model, laborsaving saving time owing to after adopting said structure, can take out continuously, inflate.
