Description

A kind of portable extension type pump

Technical field

The present invention relates to a kind of scalable inflator, but be a kind of portable tire pump of the free adjustment height that is easy to carry of process improvement design.

Background technique

Along with the fast development of economy and the progressively raising of living standard, people's spiritual demand has also obtained very big raising, and people begin more to pay attention to the grade of household articles, the aesthetic and convenience of producing product.

At present, known pump mainly is divided into three kinds of manual pump, foot-operated inflating function cylinder and electric inflators, and foot-operated inflating function cylinder and vehicle carried type pump volume are heavy especially, carry very inconvenient, manual pump has long and short two kinds, and long also being inconvenient to carried, and for short, although easy to carry, but pump in the market all need to be bent over when inflating, very inconvenient, especially concerning a part suffers from the people of LB, can cause the deterioration of disease.

Summary of the invention

The object of the invention is to: propose a kind of novelly, have very large height adjustment range and portable pump, allow people become convenient laborsaving in the inflation to bicycle etc.

In order to reach above purpose, portable extension type pump of the present invention comprises inflator top cover 1, outer cover 2, urceolus 3, base 4, foot treadle 5, leather cup 6, nut 7, packing ring 8, intermediate cylinder 9, inner core 10, middle bung 11, handle 12, seal ring 13, packing ring 14, nut 15, nut 16, packing ring 17, nut 18, leather cup 19, packing ring 20, described outer cover 2 and urceolus 3, urceolus 3 and base 4, intermediate cylinder 9 and middle cover 11, all be threaded connection, thread rotary orientation is dextrorotation, guarantees sealing.Leather cup 6 and leather cup 19 are fixed on the inner core 10 by nut (7,15) and packing ring (8,16) respectively.Above the bung, can rotate in the middle of handle 12 is fixed on, the upper end of inner core 10 is fixed with leather cup 19, and diameter and intermediate cylinder internal diameter are equal, and the lower end is fixed with leather cup 6, and diameter and urceolus internal diameter are equal, and urceolus, intermediate cylinder, inner core are hollow.

The time spent can wrap in above the intermediate cylinder 9 it with handle 12 to anticlockwise, and intermediate cylinder 9 and inner core 10 all are retracted to urceolus 3 the insides, then covers inflator top cover 1, can guarantee like this to dwindle a part of space, is easy to carry.

With the time handle 12 can be turned clockwise, make it be in level, then intermediate cylinder 9 and inner core 10 are pulled upwardly, so that leather cup 19 enters air compressing among the urceolus by inner core, then leather cup 6 enters base with the air compressing among the urceolus again, at last by tracheae output gas, because the cause of three layers of cylinder being arranged, can make that the height of inflator is higher than general portable tire pump when inflating, therefore do not need to bend over, more laborsaving, be convenient for carrying simultaneously.

The present invention relies on ingenious rational structure, solved the conventional portable pump short and small, inflate and to bend over to take in inconvenient problem with handle, handle portion is through design simultaneously, drawn the form of bird head, accomplish the design of hommization, when function satisfies, also satisfied people's aesthetic requirement.

Wherein 1 is the inflator top cover, the 2nd, and outer cover, the 3rd, urceolus, the 4th, base, the 5th, foot treadle, the 6th, leather cup, the 7th, nut, the 8th, packing ring, the 9th, intermediate cylinder, the 10th, inner core, the 11st, middle bung, the 12nd, handle, the 13rd, seal ring, the 14th, packing ring, the 15th, nut, the 16th, nut, the 17th, packing ring, the 18th, nut, the 19th, leather cup, the 20th, packing ring.

Embodiment

Embodiment: a kind of portable extension type pump (seeing accompanying drawing 5) is characterized in that mainly being comprised of inflator top cover 1, outer cover 2, urceolus 3, base 4, foot treadle 5, leather cup 6, nut 7, packing ring 8, intermediate cylinder 9, inner core 10, middle bung 11, handle 12, seal ring 13, packing ring 14, nut 15, nut 16, packing ring 17, nut 18, leather cup 19, packing ring 20.Described outer cover 2 and urceolus 3, urceolus 3 and base 4, intermediate cylinder 9 and middle cover 11 all are threaded connection, and thread rotary orientation is dextrorotation, guarantees sealing.Above the bung, can rotate in the middle of handle 12 is fixed on, the upper end of inner core 10 is fixed with leather cup 19, its diameter and intermediate cylinder internal diameter are equal, and the lower end is fixed with leather cup 6, and its diameter is identical with the urceolus internal diameter, each cylinder all is hollow, can guarantee that air passes through smoothly from the centre.

The time spent can be with the handle 12 of bird head shapes to anticlockwise, it is wrapped in above the intermediate cylinder 9, intermediate cylinder 9 and inner core 10 are all shunk downwards, make it wrap in urceolus 3 the insides, then cover inflator top cover 1, can guarantee like this to dwindle a part of space, be easy to carry, make simultaneously integral body look very succinct.

With the time handle 12 can be turned clockwise, make it be in level, then intermediate cylinder 9 and inner core 10 are pulled upwardly, to press down with handle downwards by, so that leather cup 19 is with air compressing in the intermediate cylinder, enter urceolus by inner core, then leather cup 6 continues the air compressing in the urceolus is entered base, entering at last inflator inflates to objects such as cycle tyres, because the cause of three layers of cylinder being arranged, can make that the height of inflator is higher than general portable tire pump when inflating, therefore do not need to bend over, more laborsaving, be convenient for carrying simultaneously.

Technological scheme and appearance scheme that the equal replacement of all employings or equivalent transformation form all drop within the protection domain of the presently claimed invention.
