Abstract
The utility model discloses an inflator for bicycles, comprising a cylinder block (6), a handle (9), a piston rod (2) and a piston (7). The utility model is characterized in that a saddle (1) is in a structure which can be turned over. The cylinder block (6) of the inflator is arranged in a vertical pipe (16), and the lower end of the interior of the cylinder block (6) is provided with an air valve (13) matching with the lower cover (10) of a cylinder. The upper end of the cylinder block (6) is provided with a multifunctional cylinder liner (3) which can be used for air pressure adjustment, overpressure protection and air pipe joint (27). The utility model which has the advantages of convenient use and labor saving can not be stolen separately. The utility model is suitable for inflating the tyres of bicycles, boosted vehicles, manpower vehicles, motorcycles, etc.
Description
The utility model relates to a kind of manual aerator, is used for the inflation of vehicle tires such as bicycle, mini-motorcycle.
At present, Floor Pump is adopted in the inflation of bike tyre usually, and its weak point is to be not easy to carry.Utility model patent (CN93225885.9) provides a kind of bicycle aerator that is installed on bicycle tripod or the schoolbag frame strut bar, because its gas-tpe fitting is in the bottom of cylinder block, so need perforate on spider or schoolbag frame strut bar, make troubles for manufacturing, installation.
The purpose of this utility model is exactly the deficiency that inconvenience is installed for the manufacturing that overcomes above-mentioned bicycle aerator, provide in a kind of standpipe that is installed in bicycle, gas-tpe fitting in the cylinder block upper end, be convenient to install and inflate laborsaving, can keep air pressure in the tire at the aerator of the scope of setting.
In order to reach above-mentioned purpose, the utility model adopts the turning structure of saddle (1); The cylinder block of aerator (6) is located in the standpipe (16); lower end in the cylinder block (6) is provided with the air valve (13) that matches with lower cover of air cylinder (10), and the upper end of this cylinder block (6) is provided with the Multifunctional, air cylinder sleeve (3) of scalable air pressure, overpressure protection and gas-tpe fitting (27).
Owing to adopted technique scheme, make the utility model install, easy to use, inflate laborsaving, safe and can not have things stolen separately.
Now in conjunction with the accompanying drawings the utility model embodiment is described as follows:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of Multifunctional, air cylinder sleeve of the present utility model;
Fig. 3 is a turning saddle structure scheme drawing of the present utility model.
Saddle (1) adopts turning structure; The cylinder block of aerator (6) is located in the standpipe (16); lower end in the cylinder block (6) is provided with the air valve (13) that matches with lower cover of air cylinder (10), and the upper end of this cylinder block (6) is provided with the Multifunctional, air cylinder sleeve (3) of scalable air pressure, overpressure protection and gas-tpe fitting (27).
The turning structure of described saddle (1) is meant that the front end of this saddle (1) is provided with a rotating shaft (17), and its rear end is provided with a latching device (20), and saddle pillar (18) is fixedly connected with saddle pipe (11).Multifunctional, air cylinder sleeve (3) is made of pressure regulation bolt (22), pressure spring (23), pressure regulation sealing member (24) and pronunciation reed (25).
When need are inflated, open latching device (20), upset saddle (1), make the handle (9) of aerator, piston rod (2) is in control position, handle (9) is upwards drawn, drive piston (7) and piston seal (8) upwards, the upper surface of piston seal (8) and the fitting surface of piston (7) are thrown off, the piston (7) and the cylinder contact surface of piston seal (8) are also thrown off, and form an annular space, the air of piston (7) upper end charges into the lower end of piston (7) by this annular space, contacts up to the end face of piston (7) with cylinder upper cover (4), finishes breathing process.
During inflation, handle (9) is pressed down, piston rod (2) moves downward, the lower surface of piston (7) and the planar end surface of piston seal (8) are adjacent to, piston (7) is adjacent on the cylinder of garden with the inner edge of piston seal (8), make the space between piston (7) and the piston seal (8) all eliminate, the air between the upper and lower end face of piston (7) is also isolated.When piston rod (2) continues when descending, the air of piston (7) lower end by compression, air pressure raises gradually, this atmospheric pressure has also been born in the upper surface of the air valve (13) that matches with lower cover of air cylinder (10), the atmospheric pressure that bears when air valve (13) upper surface is slightly larger than the pressure that bears air valve (13) lower surface when (comprising the pressure of the air pressure of spring 14 and bottom inner chamber (5) to air valve (13) lower surface), air valve (13) moves down, sealing member (12) on it is thrown off with the lower surface of lower cover of air cylinder (10), form the space, pressurized air in the cylinder block (6) enters bottom (15) inner chamber (5) thus, and through circular hole (19) and annular space (21,26) enter the gas-tpe fitting (27) of Multifunctional, air cylinder sleeve (3), by gas piping to Tyre inflating, make to press gradually in the tire and raise, when piston (7) arrives the following terminal point of cylinder block (6), finish once inflation.
Locating air pressure when the gas-tpe fitting (27) of bottom (15) inner chamber (5) and Multifunctional, air cylinder sleeve (3) is slightly larger than when setting up air pressure, atmospheric pressure in the air pressure adjustment chamber (28) overcomes the application force that pressure spring (23) is exchanged densification sealing (24), and pressure regulation confidential paper (24) is promoted, make the seal in itself and the Multifunctional, air cylinder sleeve (3) form the gap, make the pressurized air of superpressure charge into the hole slot of air pressure adjustment chamber one side (29) fast, make pronunciation reed (25) vibration pronunciation, air pressure in prompting operation person's inner tube of a tyre has reached setting, can stop inflation.
