Abstract

The utility model relates to a self inflator of a bicycle, which is composed of a saddle standpipe, a connecting rod, a piston, an air pipe, an air pipe joint, a bearing, a rocking arm, a support bracket, etc. The saddle standpipe of the bicycle is modified to an inflator body which utilizes the connecting rod, the piston, etc. to inflate, that is, the inflator is combined with the bicycle, and the people can use the pump at any time and any place when riding; the inflator is not limited, and can keep the normal work status of tyres at any time; the self inflator of a bicycle has convenient operation, labor saving, material saving and high efficiency.

Description

Self inflator of bicycle

The utility model belongs to a kind of bicycle Self-aid inflator.

At present, the bicycle pump great majority are the individual instruments of separating with bicycle, when bicycle need be inflated, not directly to inflating the station, be exactly to look for Floor Pump everywhere, not only time-consuming but also take merit, Nan assurance is required again, thereby the phenomenon that has caused frequent superpressure of bike tyre or low pressure to travel has greatly shortened service life of bike tyre.

The purpose of this utility model is that the bicycle saddle standpipe is adapted as air cylinder, utilizes members such as connecting rod, piston to inflate, and Floor Pump and bicycle combine.Man, woman, old, few rider can use whenever and wherever possible, and be unrestricted, so whenever all can keep the normal operating condition of tire.

The utility model is by saddle stand pipe; Connecting rod; Piston; Tracheae; The tracheae joint; Bearing; Rocking arm; The compositions such as support; With bicycle saddle stand pipe (23) as air cylinder; In-built connecting rod (22) and with the piston component (21) of check valve; Exterior outlet nozzle (20); The gentle pipe joint of tracheae (19); The connecting-rod bearing (3) that is integrated with connecting rod; Connecting axle (4); Rocking arm (13); Bearing (14); Axle (7) is integral type; Bearing (14) can rotate around axle (15); Shift rod (16) can rotate around axle (17); Support (18) front end of axle (17) is that axle saddle seat (12) front end is connected with axle (15) by rack plate (27); The rear end is by saddle spring (11); Hold-down nut (9); Set bolt (10) is connected with rocking arm (13); Crank (25) is connected with rocking arm transverse axis (7) by bearing (6); The lower end of crank (25) then inserts and is welded in the upper vertical groove (24) of clothes hanger (26), and regulating pin (1) cooperates the angle of saddle (12) to adjust with pin-and-hole (2).

The utility model and bicycle combine, and be easy to use, laborsaving, effect is high, and men and women, old and young can inflate whenever and wherever possible, and are unrestricted, whenever all can keep the normal operating condition of tire, but saving in material simultaneously.

Fig. 2 is the utility model structure internal organs view;

Fig. 3 is that the utility model B is to view.

Piston of the present utility model, tracheae, gas-tpe fitting.Bearing, bolt, nut etc. all can be bought, and all available steel such as remaining connecting rod, rocker arm support process.When riding at ordinary times, the matching relationship of Floor Pump and bicycle if need to adjust saddle height, can be adjusted joint by collar nut (7) after unclamping vehicle frame as shown in Figure 1.If adjust the upper and lower angle of saddle (12), can change cooperating of latch (1) and pin-and-hole (2), simultaneously, can cancel saddle clamp plate and bolt, nut etc.When bicycle need be inflated, earlier gas-tpe fitting (19) is pressed last tire tube valve, crank (25) is transferred to, rotate around axle (7), make fixed block (8) put pin button (5), twist pin button (5), make it block fixed block (8), successively can the upper and lower crank (25) that shakes have been inflated by bicycle.When inflating, rocking arm and saddle are that fulcrum is done upper and lower motion simultaneously with axle (15), connecting rod bearing (3), and shift rod (16) is shifted and rotates, thus connecting rod is not blocked by saddle standpipe (23) when guaranteeing to inflate.When assembling was adjusted, the front end of support (18) should exceed 1.5～2 centimetres than the rear end, best results.
