Abstract
A foot -operated pump of windy case, it includes bellows, bellows are connected in the both sides of zone of aeration, are equipped with one -way admission valve and one -way air bleeding valve on the zone of aeration. Bellows are two, respectively have bellows to connect in the zone of aeration both sides. Two corners of two bellows are equipped with each other and detain or the magic subsides for the complex primary and secondary, and the convenience is overlapped about fixing two bellows become, and can operate with single foot this moment, opening the primary and secondary and detaining or the magic subsides, spread out two bellows out, this moment is with both feet operation back and forth. Foam formula network structure packs in the bellows. The beneficial effects of the utility model are that, owing to adopt a plurality of bellows to constitute the pump, adopt both feet to make a round trip to trample, raise the efficiency, and the treader more can not tire out.
Description
Technical field
The utility model relates to a kind of pedal inflating pump, particularly a kind of windy case pedal inflating pump.
Background technique
Existing pedal inflating pump is mostly single bellows, and single foot operation is done, and such efficiency is lower.
Model utility content
The purpose of this utility model, is to provide a kind of windy case pedal inflating pump, due to multiple bellows, both feet can be adopted to trample back and forth, raise the efficiency.
The utility model is achieved in that the windy case pedal inflating pump of described one, and it comprises bellows, and described bellows are connected to the both sides of zone of aeration, and zone of aeration is provided with breather cheek valve and one-way exhaust valve.
Bellows described in the utility model are two, respectively have bellows to be connected to zone of aeration both sides.
Two corners of two bellows described in the utility model are provided with the snap button or MAGIC TAPE that coordinate each other, conveniently two bellows are fixed into upper and lower overlap, now can operate with single pin; Open snap button or MAGIC TAPE, spread two bellows out, now use double-legged passes.
One-way exhaust valve described in the utility model connects a flexible pipe, is provided with unidirectional air-stopping valve in flexible pipe.
Filled and process formula reticular structure in bellows described in the utility model.
Bellows described in the utility model are four to six, and namely two to three bellows superposed respectively are established in zone of aeration both sides, by double-legged passes.
The beneficial effects of the utility model are, owing to adopting multiple bellows to form gas-filled pump, adopt both feet to trample back and forth, raise the efficiency, and treader compare and can not tire out.
Accompanying drawing explanation
Fig. 1 is the schematic diagram that described in the utility model pair of bellows launch, and applicable both feet are trampled back and forth.
Fig. 2 is that described in the utility model pair of bellows are fixed into schematic diagram overlapping up and down through snap button, is applicable to single pin and tramples.
In figure: 1. bellows, 2. zone of aeration, 3. breather cheek valve, 4. one-way exhaust valve, 5. snap button.
Embodiment
The windy case pedal inflating pump of one described in the utility model, as shown in Figure 1, 2, it comprises bellows 1, and described bellows 1 are two, and respectively have bellows to be connected to the both sides of zone of aeration 2, zone of aeration 2 is provided with breather cheek valve 3 and one-way exhaust valve 4.Two corners of two bellows 1 described in the utility model are provided with the snap button 5 or MAGIC TAPE that coordinate each other, conveniently two bellows are fixed into upper and lower overlap, now can operate with single pin; Open snap button or MAGIC TAPE, spread two bellows out, now use double-legged passes.In order to allow gas-filled pump be connected with the person of being inflated, one-way exhaust valve described in the utility model connects a flexible pipe, is provided with unidirectional air-stopping valve in flexible pipe.Filled and process formula reticular structure in bellows described in the utility model, it contains large quantity of air, and has resilience function, plays spring action.
In order to improve charging efficiency, bellows described in the utility model are four to six, and namely two to three bellows superposed respectively are established in zone of aeration both sides, by double-legged passes.
The utility model bellows are by composite material, and as scribbled TPU, the fabric of EVA, PEVA, PU, PVC, PE etc., by sewing or bonding or ultra-sonic welded mode, forms various shape and specification.
Breather cheek valve 3 described in the utility model can join a lid, uncap during use, so that air-breathing; Establish the reverse side position of breather cheek valve 3 at zone of aeration 2, separately establish an opening, and be furnished with sealing lid, after the utility model uses, open sealing lid, namely opening loses heart, and makes foam type reticular structure shrink like this, reduces volume, is easy to carry.Certainly, also separately can not establish an opening, finish using, covered tightly by breather cheek valve lid, pin steps on gas-filled pump, allows gas run away from one-way exhaust valve 4, and foam type reticular structure is shunk, and reduces volume, is easy to carry.
Claims (6)
