Abstract

The utility model discloses a piston type high-pressure inflator, adequate to be used as the man-power inflator of bicycles, tricycles, motorcycles, etc. The utility model is provided with an air barrel, a pressing rod, a handle, steel balls, a spring, a base and an air cylinder to constitute the primary structure. The lower parts of an exhaust rubber hose, a spring clip and the pressing rod are provided with pistons and regulating nuts. The lower parts of the pistons are provided with tapered plugs. The air barrel is connected to the base with screw-threads. The base is elaborated with an exhaust vent. The piston type high-pressure inflator has the advantages of easy inflation, convenient maintenance, long service life and high work efficiency.

Description

Piston type high pressure tyre pump

The utility model piston type gas cylinder is suitable for doing bicycle, tricycle, motorcycle etc. and makes manual inflator usefulness.

The high-pressure pump of selling in the market is short working life, damage easily, leather cup particularly, use and skull patch to occur after some times, can not beat gas, adorning of more renewing is bad not air-breathing, and pump inflator and base connect extremely in addition, has impurity to clog as exhaust port and just is difficult to remove, and make inflator ineffective, even cause and scrap.

The purpose of this utility model is to provide a kind of piston type gas cylinder at the deficiency that pump exists, inflate brisk, easy to maintenance, long service life.

The piston type gas cylinder takes following mode to realize: piston type gas cylinder main structure has inflator, and inflator employing screw thread is connected with base is convenient to dismounting, maintenance cleaning.Depression bar is housed in the inflator, the depression bar upper end portion is equipped with handle, spring, bottom piston is housed, have inlet hole, steel ball is housed, piston can adopt rubber piston, piston uses fixed by nut in the depression bar bottom, piston adopts the degree of tightness of conical plug regulating piston and cylinder inner wall, if piston can tighten adjusting nut gently owing to wearing and tearing are loosening after using a period of time, conical plug is about to piston and dilates to cylinder inner wall, the recovery effect of calming the anger, the piston long service life.Rubber washer is equipped with in inflator and base joint, and to increase tightness, gas receiver is contained in the base opposite side.Inflator bottom base is processed with exhaust port and links to each other with the gas receiver inlet valve hole, and exhaust port leads to chassis outer side plug is housed, and is blocked by dirt as exhaust port, can conveniently turn on plug mediation exhaust port.The gas receiver bottom has air outlet hole and links to each other with gas cylinder exhaust rubber hose, and spring clip is housed on the rubber hose, is used for inflating fashionable dress gas enclosure door to vehicle tyre.

The piston type gas cylinder has inflates advantages such as brisk easy to maintenance, long service life, working efficiency height, the lube pistons of refueling before use better effects if.

The utility model is described in further detail below with reference to accompanying drawing.

Fig. 1 is a piston type gas cylinder structural representation.

Have in inflator (2) inflator with reference to accompanying drawing piston type gas cylinder main structure depression bar (3) is housed, handle (1) is equipped with in the depression bar upper end portion, spring (10), piston (12) is equipped with in depression bar (3) bottom, adjusting nut (13), conical plug (5) is housed in the endoporus of piston bottom, piston adjusting nut (13) regulating piston (12) and conical plug degree of tightness, thereby change the degree of tightness of piston and inflator (2) inwall, can eliminate piston and cylinder inner wall because of occurring wear gap in the using process.Depression bar (3) lower end has inlet hole (4), and relief opening is equipped with steel ball (6).Depression bar also can adopt the hollow pipe to make.Inflator (2) is connected in order to increase sealing with base (9) with screw thread, be convenient to the inflator mounting or dismounting, rubber washer (7) also is equipped with in the joint, being processed with exhaust port (8) on the base (9) links to each other with gas receiver (9) inlet valve hole, lean against chassis outer side plug (14) is housed, can conveniently install and remove and clean the exhaust port dirt.Gas receiver is installed on the base (9), and near pump (2), gas receiver (9) bottom has air outlet hole and gas cylinder exhaust rubber hose (10) joins, and spring clip (11) is contained on the outlet nozzle of exhaust rubber hose.
