Abstract
The utility model relates to a portable folding high pressure inflator, comprising a draw rod, a handle part, a cylinder body part, an air storing cylinder part, etc. The utility model is characterized in that the air storing cylinder body is arranged in the cylinder body; a one-way valve is arranged in the air storing cylinder, and a piston cylinder-body cover is arranged between the cylinder body and the cylinder body; an air cavity which is sealed by an O-shaped sealing ring is formed between the piston cylinder-body cover and the cylinder body. The handle, the draw rod, a crank, and the piston cylinder-body cover are in movable connection, and are foldable. The utility model has the advantages of small volume, light weight, foldable property, convenient carrying, etc. The utility model is particularly suitable for using as the stand-by tool for the outgoing travel by bike.
Description
The utility model relates to the improvement of a kind of inflator structure in the field of mechanical technique.The shortcoming that the pump that existing market occurs exists is the side that the gas storage bag places pump cylinder.This inflator volume is big and seem heavy, is unfavorable for that the cyclist's is easy to carry.
The purpose of this utility model is to overcome the deficiencies in the prior art part, adopted pull bar to fold and placed the interior design proposal of pump cylinder with gas receiver, also traditional leather bucket structure is improved simultaneously, it is small and exquisite to make that this portable folding high-pressure pump has, and inflates evenly laborsaving and the advantage easily that is easy to carry.
The portable folding gas cylinder takes following scheme to realize, with reference to accompanying drawing 1.
This pump is mainly by pull bar handgrip part, shell portion, and the gas receiver part, the one-way valve part, base portion is formed.Pull bar handgrip part is made up of handgrip 9, pull bar 10, rivet 7, crank 18.Shell portion is made up of upper shield 6, cylindrical shell 11, cover 17.The gas receiver part is made up of storing gas 12, piston gas storage cover 14, " O " shape seal ring 15.Base portion is made up of base 1, plug screw 2, spring 3, foot-operated 4, steel ball 5, steam outlet pipe 28.The one-way valve part is made up of valve body 27, rubber seal 26, steel ball 25, swivel nut 24, tracheae 23, nut 22, spring washer 21.
The utility model is reasonable in design, compact structure.Its novel part is: gas storage cylindrical shell 11 places in the pump cylinder 10, has played the effect of reduced volume; Gas receiver can store the effect that pressurized gas have also played the conventional piston bar; The piston gas receiver covers " O " shape seal ring is housed, because this piston structure is air-breathing fully, inflates and does not leak, so replaced traditional piston cup structure; The handgrip part of inflator is flexible folding when collection, can draw back during use, and available setting sleeve 8 fixes the connection curved section of pull bar 10 and crank 18 and cover 17.
Be further described below in conjunction with 1 pair of the utility model of accompanying drawing.
With reference to accompanying drawing 1, the handgrip of inflator part is connected by the end with handgrip 9 and pull bar 10 such as rivet 7 or pin, and be the fulcrum rotation with rivet 7.The other end of pull bar 10 passes setting sleeve 8 by rivet 19 or pin etc. and 18 movable connections of crank.Shell portion is by upper shield 6 and cylindrical shell 11 scyewed joint, the other end of cylindrical shell 11 and cover 17 scyewed joint, and cover 17 is again by rivet 20 or pin etc. and 18 movable connections of crank.The gas receiver part is by gas storage cylindrical shell 12 1 ends and base 1 scyewed joint, and the other end and piston gas receiver 14 scyewed joint are equipped with " O " shape seal ring 15 on the piston gas dome.Base portion is fixed on spring 3, steel ball 5 in the hole of base 1 by plug screw 2.Foot-operated 4 and gas outlet 28 be contained in respectively on the base 1, the one-way valve part is passed nut 22 and packing ring 21 and piston gas storage cover 14 scyewed joint by an end of tracheae 23, the other end and valve body 27 scyewed joint, rubber seal 26 is contained in the valve body 27, and steel ball 25 places on the rubber seal 26.By swivel nut 24 and valve body 27 scyewed joint, make the activity of steel ball 25 be able to spacing.
The use working principle of portable folding gas cylinder is as follows: during use handgrip is partly pulled to the side, make handgrip part and shell portion place straight line, simultaneously with setting sleeve 8 with pull bar 10 and crank 18 and cover 11 3 partial fixings firmly.Put down and ride 4, stir 10 one-tenth vertical positions of handgrip 9 and pull bar, as shown in Figure 2.
With reference to accompanying drawing 1 and accompanying drawing 2.When using inflator, holding handgrip 9 drive cylindrical shells 11 moves upward, because causing on " O " shape seal ring 15, the frictional force between cylindrical shell 11 and " O " shape seal ring 15 moves, make the vent slot on the piston gas dome connect by the vent slot 29 and the atmosphere of upper shield 6, in the abundant suction cylindrical shell 11 of air, " O " shape seal ring 15 moves down when holding handgrip 9 and pressing down, the vent slot of piston gas dome is shut, make the air that sucks in the cylindrical shell 11 pass through tracheae 23, back down steel ball 25, be pressed into fully in the gas storage cylindrical shell 12, after this steel ball 25 falls, because the effect of steel ball 25 can only be advanced in the gas receiver air in the cylindrical shell 11, and can not be flow backwards.Motion and so forth makes to form pressurized gas in the gas storage cylindrical shell that air-flow will enter in the tire by air outlet hole 30 and steam outlet pipe 28 uniformly.
Because the utility model is in the handgrip part, the gas receiver part, piston gas dome part one-way valve partial design is new reasonable, and it is laborsaving to make this inflator inflate, and air inlet is even, and is in light weight, collapsible, is convenient to collection and carries.
