Abstract

The utility model relates to a high-and low-pressure inflating pump, which is composed of a motor, a speed reducing gear, a connecting pin, a piston, a suction cup, etc. Two cranks are sheathed on the connecting pin, the two cranks are driven by the motor, and the gas with high-and low-pressure can be extruded by the piston and the suction cup that are driven by the crank. The utility model is suitable for the inflating products, such as a tyre, plastic, etc. That need the inflation pump for different inflation pressure requirements. The high-and low-pressure inflating pump has the advantages of dual purpose and convenient operation.

Description

The inflating pump that high-pressure and low-pressure is dual-purpose

The utility model relates to a kind of inflating pump, refers to a kind of different dual-purpose inflating pumps of high-pressure and low-pressure of inflation pressure height such as tire or plastic object that are suitable for especially.

In the daily life, often need inflate some object, as: amusement and leisure equipment such as tire, inflatable toys, balloon and rubber dinghy; when inflatable substrate is inflated; the air pressure deficiency takes place in regular meeting, fails to reach the optimum state of inflatable substrate, promptly needs this moment to inflate with inflating pump.

Yet be broadly divided into two classes with regard to the character that inflatable substrate is inflated, a class such as tire or ball etc. needs high-pressure aerated, the low inflation of another kind of toy for the needs lowpressure, balloon or rubber dinghy.Its mesohigh with inflating pump its to inflate speed slower but inflatable in the inflatable substrate of high pressure; The speed that low pressure is inflated with inflating pump is very fast, but only inflatable in the inflation body of low pressure.Filling low pressure with the high pressure inflating pump when inflating thing, or when aerating high-pressure aerated thing, be not to inflate, can produce danger exactly with the inflating pump of low pressure.Therefore in order to adapt to two kinds of inflatable substrates of different nature, often need to purchase two kinds of inflating pumps, cause the inconvenience in the use, and the trouble in the keeping maintenance.

The purpose of this utility model is promptly to drive the inflating pump that provides a kind of high-pressure and low-pressure dual-purpose two cranks by a motor, and drive piston and sucker simultaneously, produces high pressure and two kinds of character air of low pressure, to adapt to the demand of different inflatable substrates.

The technical solution of the utility model is such: it comprises elements such as motor, reduction gear, connection pin, piston and sucker, wherein cover unification driving gear on the transmission shaft of motor; Reduction gear is meshed with driving gear, and is provided with rotating shaft in the reduction gear centre, a sheathed cam in the rotating shaft; Connection pin is arranged at the appropriate location in the cam outside, sheathed two cranks on the connection pin; Piston combines and embeds in the cylinder with a crank wherein; Sucker combines with another crank, and is clamped between panel and the ring plate.

Inflating pump recited above, wherein: cylinder is provided with suction port and air outlet and establishes suction valve respectively and gas outlet valve is controlled unidirectional unlatching; And also be provided with suction port and air outlet on the panel, establish suction valve and gas outlet valve respectively and control unidirectional unlatching; After the combination, drive by motor, make two cranks drive respectively piston and sucker with compression, draw the pressurized air of releasing high pressure and low pressure.

Below in conjunction with drawings and Examples the utility model being done one describes in detail.

Fig. 1 is textural association figure of the present utility model;

Fig. 2 is an action schematic representation of the present utility model;

Fig. 3 is another action schematic representation of the present utility model;

Fig. 4 is an External view of the present utility model.

Consult shown in Figure 1ly, the utility model is made up of elements such as motor 1, driving gear 12, reduction gear 2, cam 22,

crank

31,32, piston 4 and suckers 5; Wherein driving gear 12 is sleeved on the transmission shaft 11 of motor 1, outer rim and a reduction gear 2 engagements; Cam 22 centers are sleeved in the rotating shaft 21 of reduction gear 2 central authorities, and in outside appropriate location pin joint one connection pin 3, with

socket crank

31,32,

crank

31,32 tops are affixed piston 4 and sucker 5 respectively.And piston 4 is arranged in cylinder 43, and 5 in sucker is clamped on 54 of panel 51 and ring plates.

Cylinder 43 and panel 51 are provided with suction port 41,511 and air outlet 42,512 in appropriate location, and suction port 41,511 and air outlet 42,512 are respectively by

suction valve

44,52 and

gas outlet valve

45,53 control air one-way trips.

Consult Fig. 1,2 and shown in Figure 3, motor 1 outputting power is through driving gear 12, reduction gear 2, make cam 22 and reduction gear 2 do equifrequent melody, and cam 22 rotations drive the

crank

31,32 on its outside connection pin 3 of fit, make the piston 4 upper and lower slip in cylinder 43 on the crank 31, crank 32 then repetitiousness draws and pushes away sucker 5.When crank 31 promoted on the pistons 4 sliding extruding air, suction valve 44 cut out and air ejection gas outlet valve enters in the inflatable substrate; When piston 4 descends, gas outlet valve 45 is closed in the air pressure ejection of inflatable substrate, ambient air then is inhaled in the cylinder 43 by suction valve 44, treat that piston 4 pressurized air that rises again overcomes inflatable substrate air pressure and then backs down the air that gas outlet valve 45 will compress high pressure and pour in the inflatable substrate, pressure and volume are inversely proportional in the seal container, the volume that air enters in the inflatable substrate in the each compression cylinder 43 of inflatable substrate pressure is fewer, therefore be suitable for that inflatable substrate air pressure uses when big but more time-consuming, as be used for the inflatable substrate of highpressure such as tire.

Crank 32 is drawn by cam 22 rotation repetitiousness also and pushes away sucker 5, air is inhaled between sucker 5 and the panel 51 in the crack via suction valve 52, ejection is pressed in the inflatable substrate via gas outlet valve 53 again, because of 5 in sucker as elastomer, 51 of sucker 5 and panels can be made bigger compression volume, but can't compress the air that highpressure compares, thus be applicable to air pressure more very fast than less demanding inflatable substrate and inflation rate, as the inflatable substrate of life ring of balloon, plastic cement system etc.

As shown in Figure 4, above-mentioned element is assembled in the housing 6, the top of housing 6 is a handle 61, can be turned round by motor behind the power connection 7 connection power supplys.

Consult Fig. 1 and shown in Figure 4, utilize a motor 1 to drive two

cranks

31,32 simultaneously and drive piston 4 and sucker 5 respectively, with the pressurized air that compresses high pressure or low pressure to be fit to different inflatable substrates; And crank 32 drives suckers 5 compressions fast and the air of low pressure, still can utilize to do air releasing device and use, and makes the suction port of inflatable substrate connect the suction port 511 of panel 51, can make the sucker 5 of crank 32 drive dump air 512 discharges from the air outlet of inflatable substrate fast.Be a maintenance and all good easy product of use.

In sum, the utility model utilizes single motor to drive the pressurized air that two cranks produce the pressure difference respectively, with the inflatable substrate inflation that is fit to high pressure or low pressure or lose heart, has the effect of a thing dual-purpose, and easy to use, practicability is good.
