Abstract
The utility model relates to a pedal inflating pump which belongs to the machinery sort. A bracket 5 is rotatablely connected with a cylinder bottom axis 6, a commutator assembly 7 is fixed on the cylinder axis 6, and the commutator assembly, a cylinder 8 and an upper cover 9 of the cylinder are fixedly connected together by a cylinder locking screw rod 18. A piston return spring 10 is sheathed with a piston rod 16, a gas output conduit 11 is connected with the commutator assembly 7, a manometer 17 is connected with the gas output conduit, and a pedal rod 12 is fixedly connected with a force arm 13. An upper axis 14 of the cylinder and a main axis 15 are respectively and rotatablely connected with the force arm, and the main axis is fixedly connected with the bracket 5. One end of the return spring 1 of a one-way valve is fixedly connected with a casing 4, the other end of the return spring 1 of the one-way valve is fixedly sheathed with a one-way valve core 2, and the casing 4 is provided with a one-way valve 3. The utility model has the advantages that the pedal inflating pump has convenient use, favorable mechanical strength, durable use, high air pressure output and large air flow, and can be widely suitable for the tire inflation, etc. in the field operation and the running mechanical operation without using the power supply.
Description
Technical field
The utility model relates to mechanical, and particularly a kind of foot-operated gas-filled pump refers to a kind of gas-filled pump without power supply that is widely used in inflations such as oil field, railway, court, skin rowboat, automobile especially.
Background technique
As everyone knows, the inflator of Chu Shouing mainly is a pump in the market, but inflator structure commonly used is all simpler and easy, mechanical strength is also poor, very easily damage, and maximum weakness is that output pressure is low, output tolerance is few, does not satisfy the demand of all trades and professions on the market, is badly in need of being improved.
Summary of the invention
The purpose of this utility model is in order to overcome the bad mechanical strength that above-mentioned inflator commonly used exists, very easily to damage, and the problem that output pressure is low, tolerance is few provides a kind of foot-operated gas-filled pump.Its concrete technological scheme is: support 5 is rotationally connected with cylinder lower shaft 6, commutator assembly 7 is fixed on this cylinder axis 6, this commutator assembly, cylinder 8 and cylinder upper cover 9 are fixed together by cylinder locking screw 18, piston reset spring 10 and piston rod 16 sockets, gas output duct 11 is connected with commutator assembly 7, pressure gauge 17 is connected with this gas output duct, treadle 12 is fixedlyed connected with the arm of force 13, axle 14 and main shaft 15 are rotationally connected with this arm of force respectively on the cylinder, and this main shaft is fixedlyed connected with support 5; One end of one-way valve Returnning spring 1 is fixedlyed connected with housing 4, and the other end and one-way valve spool 2 are fixedly sleeved, and housing 4 is provided with one-way valve 3.Principle of the present utility model is: when external force acts on treadle 12, axle 14 moves downward cylinder 8 inner carriers to pressing down on the arm of force 13 drive cylinders, and gas is extruded and produce certain pressure, this pressure≤1.2Mpa, general conventional electric power drags the air pressure of air pump equipment below 1.0Mpa; Pin is lifted after trampling treadle 12 on earth, piston reset spring 10 is withdrawn into initial position with piston immediately again, prepares next action beginning, and to-and-fro motion will have endlessly pressurized gas export by gas output duct 11 like this; After last working piston moved to the bottom gas is discharged, piston reset spring 10 retracted piston, and at this moment cylinder 8 need replenish into sufficient air and finish the next operation cycle; Input and output gas mainly drives 7 work of commutator assembly by the motion of piston, in the time of the piston resilience, cylinder 8 bottoms produce a negative pressure, and this negative pressure is drawn back one-way valve spool 2, air fully enters in the cylinder 8, when piston moved downward, gas was discharged by one-way valve 3, for one-way valve spool 2, gas produces a pressure this one-way valve spool is resetted, seal gas, thereby in cylinder 8, produce air pressure, gas is discharged the produce power acting.
Advantage of the present utility model is: easy to use, mechanical strength is good, and is durable in use, and output pressure height, large-minded is widely used in the field and does industry and the tyre inflation used of running mechanism industry etc., and without power supply.
