Abstract
The utility model discloses a pedaled air pump. The pedaled air pump comprises a pump body, one-way valves and a piston. The pump body comprises a working chamber. The piston divides the working chamber into an upper chamber and a lower chamber. The piston is connected with a connecting rod which extends out of the upper chamber. The lower chamber is provided with a spring which drives the piston to move upwards. An air inlet one-way valve and an air outlet one-way valve are mounted on the top of the upper chamber or at the bottom of the lower chamber. According to the pedaled air pump, the spring drives the piston to move upwards and return; the air inlet one-way valve and the air outlet one-way valve are arranged on the upper chamber or the lower chamber as needed to form the air pump. The pedaled air pump is simple in structure, convenient to carry, capable of achieving the air pumping function and the pressurizing function, convenient to operate, practical, and capable of meeting multipurpose requirements of an extinguishment site.
Description
Technical field
The utility model belongs to Machine Design and makes field, particularly a kind of pedal inflating pump.
Background technique
Existing air pump adopts piston type usually, utilizes piston moving back and forth back and forth in inflator to realize bleeding or supplying gas, and moving around of piston all needs external force to drive.In the fire-fighting fire extinguishing process, usually need a kind of air pump portable, easy to use, particularly plant when operation carrying out the multiplex (MUX), need to vacate hand and carry out air pump driving operation with pin, with the on-the-spot preparatory work before the equipment operations such as convenient fire extinguishing water pump, existing pedal inflating pump complex structure can't be satisfied the demand.
Summary of the invention
The utility model discloses a kind of pedal inflating pump according to the deficiencies in the prior art.Problem to be solved in the utility model provide a kind of simple in structure, easy to carry, can realize bleeding and pressurization function, and easy to operate practicality pedal inflating pump.
The utility model provides following technological scheme to realize:
Pedal inflating pump comprises the pump housing, one-way valve and piston, it is characterized in that:
The described pump housing comprises active chamber, and piston is divided into upper and lower chamber with active chamber, and piston is connected with the connecting rod that stretches out upper chamber, and lower chambers is provided with the up spring of driven plunger;
Described upper chamber top is equipped with breather check valve and outgassing nonreturn valve;
When breather check valve and outgassing nonreturn valve were installed by described upper chamber, connecting rod and active chamber sliding contacting part had seal ring, and the pore that is communicated with atmosphere is arranged at the lower chambers bottom.
Another kind of mode also can be equipped with breather check valve and outgassing nonreturn valve in the lower chambers bottom.
When breather check valve and outgassing nonreturn valve were installed in described lower chambers bottom, the pore that is communicated with atmosphere was arranged at the upper chamber top.
For foot-operated driven plunger is stable, be provided with foot treadle at the connecting rod top.Foot treadle adopts larger flat board and the connecting rod of area to be connected and fixed formation, can also annular projection be set or other can increase the structure of friction at dull and stereotyped upper surface.
The utility model helpfulness, shape is replied on the utility model Spring driving piston, in upper chamber or lower chambers breather check valve and outgassing nonreturn valve formation air pump are set as required, the utility model is simple in structure, easy to carry, can realize bleeding and pressurization function, and easy to operate, practical, be fit to fire-extinguishing location multipurpose needs.

Embodiment
Below by embodiment the utility model is conducted further description; present embodiment only is used for the utility model is further detailed; but can not be interpreted as the restriction to the utility model protection domain, those skilled in the art can make the scope that some nonessential improvement and adjustment belong to the utility model protection according to above-mentioned content of the present utility model.
In conjunction with Fig. 1 to Fig. 2.
Pedal inflating pump comprises the pump housing, one-way valve and piston, and the pump housing comprises active chamber 5, and piston 4 is divided into upper and lower chamber with active chamber 5, and piston 4 is connected with the connecting rod 1 that stretches out upper chamber, and lower chambers is provided with the up spring 6 of driven plunger 4.
The upper chamber top is equipped with breather check valve 2 and outgassing nonreturn valve 3.
Connecting rod 1 has seal ring with active chamber 5 sliding contacting parts, and the pore that is communicated with atmosphere is arranged at the lower chambers bottom.Connecting rod 1 top is provided with foot treadle 7.
As depicted in figs. 1 and 2, this routine active chamber 5 arranges breather check valve 2 and outgassing nonreturn valve 3 for the cylindrical body of sealing on cylindrical body top, connecting rod 1 is connected with piston 4, connecting rod 1 has seal ring one to guarantee the seal of active chamber 5 with active chamber 5 sliding contacting parts, and connecting rod 1 top is provided with foot treadle 7.Foot treadle 7 adopts larger flat board and the connecting rod 1 of areas to be connected and fixed formation, can also annular projection be set or other can increase the structure of friction at dull and stereotyped upper surface.Lower chambers that piston 4 is separated to form is installed and is provided with spring 6, and when piston 4 compressions were bled, spring was compressed, naturally unclamp connecting rod 1 after, driven plunger 4 exhaust that resets that releases energy of compressed spring 6.
This routine breather check valve 2 and outgassing nonreturn valve 3 are arranged on cylindrical body active chamber 5 tops.When bleeding, breather check valve 2 is communicated with the needs evacuated vellel, outgassing nonreturn valve 3 is communicated with atmosphere; Step connecting rod 1 and foot treadle 7, the volume of active chamber 5 changes, and finishes and bleeds, naturally unclamp connecting rod 1 and foot treadle 7 after, driven plunger 4 exhaust that resets that releases energy of compressed spring 6.
In conjunction with Fig. 3, this example is installed in the lower chambers bottom with breather check valve 2 and outgassing nonreturn valve 3 settings, and the pore that is communicated with atmosphere is arranged at the upper chamber top.Other structure is substantially the same manner as Example 1.Connecting rod 1 and foot treadle 7 are not expressed among Fig. 3.
When bleeding, breather check valve 2 is communicated with the needs evacuated vellel, outgassing nonreturn valve 3 is communicated with atmosphere; Step connecting rod 1 and foot treadle 7, the volume of active chamber 5 changes, and finishes exhaust, naturally unclamp connecting rod 1 and foot treadle 7 after, compressed spring 6 driven plunger 4 that releases energy resets and bleeds.
