Abstract
The utility model relates to a hand mini-inflator, which relates to the field of a device for inflating a tyre, in particular for a portable vehicle inner tyre for a bicycle, etc. The utility model is composed of a casing body, a rotor and a sealing apical plate, the rotor is eccentrically arranged in the inner chamber of the casing body, and the rotor and the casing body are contacted at one point. One end of the sealing apical plate is contacted with the rotor, the other end of the sealing apical plate is connected with a spring in the casing body, the casing body is provided with an air inlet and an air outlet, and a crank handle is connected with the rotor. The utility model has simple structure, easy fabrication, strong practicability, small size and convenient carrying, and the utility model is an ideal portable hand mini-inflator.
Description
The miniature hand inflator pump of the utility model relates to roadster inner tube of a tyre inflations such as Tire Inflation System field, particularly bicycle.
The piston type pump is adopted in existing roadster inner tube of a tyre inflation, and volume is big, portably uses inconvenience.
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, and volume is little, portably uses miniature easily hand inflator pump.
The purpose of this utility model reaches by following measure, it is made up of housing, rotor, sealing top flat, in the housing inner chamber, the eccentric rotor of settling, rotor and housing are tangential on a bit, and sealing top flat one end contacts with rotor, and an end is connected with spring in housing, port is arranged on housing, and wind links to each other with rotor.The contact of the point of contact of rotor and housing and sealing top flat and rotor is divided into two upper gas chambers with the inner chamber of housing, with the rotation of rotor, inlet hole is entered into the air compression of housing inner chamber, discharges from exhaust port, reaches the purpose to tyre inflation.In order to improve the sealing between rotor, housing inner chamber, the sealing top flat, can a seal ring be installed on rotor, be enclosed within on the rotor, the seal ring that seal ring is made by skeleton and flexible material is formed.But slide relative between seal ring and rotor makes seal ring become relative rolling with the housing points of tangency by slide relative, thereby has reduced friction, has strengthened serviceability, and has reduced the machining accuracy to inner walls, rotor, makes product be easier to processing and fabricating.
Sealing top flat of the present utility model also can adopt and be installed on the rotor, and an end contacts with the housing inner chamber, and an end is connected with spring in rotor, and the sealing top flat can be installed 1～3.At the housing inner chamber seal ring can be set also.
For easy to use, rapid, on exhaust port of the present utility model, connect a supercharging gas storage chamber, at the suction port of supercharging gas storage chamber one one-way valve is arranged.
The utility model is simple in structure, makes easily, and practical, volume is little, and is easy to carry, is the hand inflator pump of a kind of desirable portable minisize.
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is an external structure schematic representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is further described:
Shown in accompanying drawing 1, accompanying drawing 2, the utility model is made up of housing (3), rotor (4), sealing top flat (7), wind (10), port (6), (9), supercharging gas storage chamber (2) and seal ring (5), in housing (3) inner chamber, the eccentric rotor (4) of settling, rotor (4) is tangential on a bit with housing (3), go up installation one seal ring (5) at rotor (4), be enclosed within on the rotor (4), seal ring (5) is made up of skeleton and seal ring, skeleton is enclosed within on the rotor, and the seal ring of being made by elastic material is arranged on the skeleton.Sealing top flat (7) one ends contact with rotor (4), and an end is connected with spring (8) in housing (3), and port (6), (9) are arranged on housing (3), and wind (10) links to each other with rotor (4).Go up to connect a supercharging gas storage chamber (2) at exhaust port (9), an one-way valve (1) is arranged at the suction port of supercharging gas storage chamber (2).Shake handle (10), driving rotor (4) rotates, the contact of the point of contact of rotor (4) and housing (3) and sealing top flat (7) and rotor (4) is divided into two air chambers with the inner chamber of housing (3), rotation with rotor (4), inlet hole (6) is entered into the air compression of housing (3) inner chamber, discharge from exhaust port (9), reach purpose to tyre inflation.
Claims (3)
1, a kind of miniature hand inflator pump, it is characterized in that forming by housing, rotor, sealing top flat, in the housing inner chamber, the eccentric rotor of settling, rotor and housing are tangential on a bit, and sealing top flat one end contacts with rotor, and an end is connected with spring in housing, port is arranged on housing, and wind links to each other with rotor.
2, miniature hand inflator pump according to claim 1 is characterized in that a seal ring is installed on rotor, is enclosed within on the rotor, and seal ring is made up of skeleton and seal ring.
3, miniature hand inflator pump according to claim 2 is characterized in that on the exhaust port connecting a supercharging gas storage chamber, at the suction port of supercharging gas storage chamber one one-way valve is arranged.
