Abstract
Disclosed is a single tube high pressure type pump which an inflation tool for bicycles, human powered rubber tire carts, tractors, etc. The utility model is similar to the common single tube pump in appearance and structure, and is characterized in that an oil-resistant rubber ring in O shape is assembled on the piston in an air tube; a conical surface which can seal closely with the oil-resistant rubber ring in O shape on the piston; a high pressure air chamber composed of a high pressure valve, a steel ball in the high pressure valve and a spring is also installed in the air tube; the high pressure air chamber is communicated with a rubber pipe by a high pressure channel. Compared with the common single tube pump and the double tube pump, the utility model has the advantages of long service life, low cost, high pressure efficiency, labor saving, uneasy heating of the air tube, convenience and materials saving.
Description
The utility model relates to a kind of high-pressure pump of improved pump, particularly single tube, is suitable for the inflatable tool of bicycle, manpower rubber-tired cart etc.
The pump that generally uses has two kinds now, and a kind of is the single tube pump, and another kind is a double-barreled pump.These two kinds of pumps all have the ox-hide leather cup on endotracheal piston, and the ox-hide leather cup is aging easily, usually will change, and are cumbersome when repair and replacement, generally need the mechanic to keep in repair; Because ox-hide leather cup and tracheal wall contact friction face are big, when the operating time was long slightly, tracheae is heating just, and was more obvious when giving manpower rubber-tired cart, hand tractor aerating; Especially be difficult to inflation after the ox-hide leather cup wears out, efficient is low.Then use inconvenience.Double-barreled pump is Duoed a tracheae than the single tube pump, can produce high pressure in this tracheae, and people feel more laborsaving than single tube pump when using double-barreled pump, efficient is high, but double-barreled pump will consume a steel pipe more, the cost height, price is expensive, and weight increases uses inconvenience.
The utility model provides a kind of improved pump, and this pump is that a kind of more existing pump can improve charging efficiency, increases the service life, the high-pressure pump of economical with materials, single tube easy to use.
This single tube high-pressure pump profile and structure are similar with common single tube pump, it has inflator base and connected tracheae, have an end of piston rod, piston rod that piston is arranged in tracheae and be fixed with nut, the end in addition of piston rod stretches out the tracheae outer fixing handle, one end of sebific duct is connected with the inflator base, end connection duck chews folder in addition, be characterised in that on piston, to be equipped with O type oil-resistant rubber ring, and on piston, have can with the conical surface of O type oil-resistant rubber ring driving fit; Also has the plenum chamber that in tracheae, constitutes by the steel ball in high pressure valve and the high pressure valve, spring.And plenum chamber communicates with sebific duct by the passage of calming the anger.
The single tube high-pressure pump is owing to adopt O type oil-resistant rubber ring, and on piston, have can with the conical surface of O type oil-resistant rubber ring driving fit, sealability is fabulous, simultaneously because plenum chamber is arranged in tracheae, the efficient of calming the anger height, easy to use, laborsaving; Also, do not generate heat during use, pour and change conveniently, and high pressure valve is wear-resistant because O type oil-resistant rubber ring and tracheal wall surface of contact are minimum; Also have economical with materials, cheap advantage in addition.
Accompanying drawing is the structural representation of single tube high-pressure pump.
Now in conjunction with the accompanying drawings the utility model is described in detail.
The single tube high-pressure pump has the base same with common pump (1), make of plain cast iron or spheroidal graphite cast iron, the tracheae (2) that the electrically welded tube of any caliber is made among employing specification φ 28mm to the φ 35mm is connected with base (1), the piston rod (3) that useful φ 10mm cold-drawn round steel is made in tracheae (2), the one end has piston (4), be fixed with nut (5), piston (4) is that nylon or ABS plastic or plexiglass are made with material, wear-resistant, the end in addition of piston rod (3) stretches out outside the tracheae (2), and be fixed with an end of wooden handle (8) sebific duct (7) and be connected with the passage of calming the anger (13) on the inflator base (1) and communicate, end connection duck chews folder in addition, on piston (4), be equipped with an O type oil-resistant rubber ring (6), and on piston (4), have can with the conical surface (14) of O type oil-resistant rubber ring (6) driving fit, the O type oil-resistant rubber ring (6) and the conical surface (14), tracheae (2) inner wall sealing performance is fabulous, and the interior gas pressure of tracheae (2) is high more just tight more, the efficient of calming the anger is just high more, in tracheae (2) lower tube, a plenum chamber (10) is arranged, this plenum chamber (10) is by the steel ball (11) in high pressure valve (9) and the high pressure valve (9), spring (12) constitutes, high pressure valve (9) is that nylon or ABS plastic or plexiglass are made with material, plenum chamber (10) communicates with sebific duct (7) by the passage of calming the anger (13), be assemblied on the piston (4) O type oil-resistant rubber ring (6) can along with the pressurized gas pressure change at A, the B position translation, when piston (4) moves downward, O type oil-resistant rubber ring (6) is in the B position, when piston (4) moves upward, O type oil-resistant rubber ring (6) moves to the A position.When bicycle or manpower rubber-tired cart inner tube of a tyre unsaturated vapor, the pore that duck is chewed folder is aimed at the inner tube valve core and is clamped, hold handle (8) and down calm the anger, at this moment O type oil-resistant rubber ring (6) is in the conical surface (14) driving fit of B position and piston (4), and tracheae (2) bottom pressure increases; Hold handle (8) when up carrying O type oil-resistant rubber ring (4) move to A position, at this moment air inlet.When calming the anger several times repeatedly, form a high pressure area in tracheae (2) bottom, steel ball (11) in the plenum chamber (10) is backed down by air-flow simultaneously, pressure spring (12), gas enters sebific duct (7) by the passage of calming the anger (13), because the air pressure in the vehicle tyre is well below the interior air pressure of plenum chamber (10), thereby gas charges into inner tube by sebific duct (7).When work finishes, spring (12), steel ball (11) all restore to the original state.If will change O type oil-resistant rubber ring (6), only need the primary nut on tracheae (2) top is outwarded winding, with small screw driver old circle replacing is got final product.
