Fig. 5 is the part sectional view of inflator parts among Fig. 1.

One, inflator parts (referring to Fig. 1, Fig. 5). It is the Self-carried type inflator that adds the transformation of the way of other part with vertical pipe of bicycle frame and saddle pipe.

1, seat tube (1) is done inwall polishing, reducing the wearing and tearing of leather cup, and termination, its underpart (2) are sealed; Left side in vehicle frame lower contact (3) and standpipe contact portion processes a facet (4), the center is left a tapped venthole (5), the little catch (7) of loading onto a near-rhombic, can turning left with a little rivet (6) on the facet in left side, hole is in case mud, dirt etc. enter standpipe.

2, make push rod (8) with one section thinner steel pipe, hide with its inner space and put the air guide sebific duct; Handle (9) is made of plastic, and top is round pie, and the bottom is cylindric when inflation (in order to avoid finger dampened), and there is the circular hole of perforation the center, with clampings push rod on; The push rod lower end is filled in a nut (10) and is welded.Push rod is passed saddle pipe (11 from the upper end, make induction opening with crack generation between the two) after, with a lag bolt (12) and a locknut (13) leather cup (14) and upper and lower packing ring (15,16) are fastened on the nut of push rod lower end, put into standpipe afterwards, saddle fixation.

3, the front end of air guide sebific duct (17) has negative thread (with the outside thread coupling of plunger on the wheel), trailing portion that the rotary ozzle (18) of rubber cradle is arranged with a leading portion, replaces common duck bill clip, puts and prevent gas leakage so that hide; Its rear end then is a fixed type ozzle (19), there are outside thread (with the negative thread coupling of air gate in the vehicle frame lower adaptor) and little round platform (an ox-hide packing ring ［ 20 ］ is equipped with in its front) in the front portion, middle have an embossing handwheel near air guide sebific duct place, so that free-hand demolition, installation air guide sebific duct.

Two, saddle parts (referring to Fig. 2, Fig. 3, Fig. 4).It is with the open-close type saddle of two upright spring saddle (non-other type) transformations of the way, and this is the critical component of this device.

1, with a thin steel rod crossbeam at two upright spring saddle rear portions, changes the upper and lower double-ply steel plate of purpose made crossbeam into.Respectively there is a circular hole two ends and the centre of upper and lower crossbeam (21,22), and the Kong Jun at two ends has screw thread, middle Kong Junwu screw thread; Entablatrance thin (because of the pitch of bolts at two ends little), the aperture is little, bent intermediate place vertical dimension is big, cross sill thicker (because of the pitch of bolts at two ends big), the aperture is big, bent intermediate place vertical dimension is little.

2, two plain bolts of upright spring (23) lower end of two upright spring saddles, change big half by the termination into and do not have screw thread, the termination is hemispheric special bolt (24), it is penetrated under the upright spring behind the hole, the tapped bore that is screwed into the entablatrance two ends is interior fastening, threadless big half exposes, and cooperates with the hollow bolt with the cross sill two ends; Again an isometric with it plain bolt (25) is passed the circular hole of entablatrance centre from top to bottom,, cooperate with special wing nut with the cross sill centre with locknut (26) locking.The above has just constituted the top of open-close type saddle.

3, two purpose made hollow bolts (27) bigger than the diameter of bolt at entablatrance two ends are penetrated the metapore (28, the corresponding increasing in aperture) of saddle clamp beam from below, be tightened in the tapped bore at cross sill two ends, its termination flushes with the top edge of tapped bore; Again with a special wing nut (29) that has one section fine steel tube (outer fluted), one section of fine steel tube pierced into circular hole in the middle of the cross sill from bottom to top after, block a circular jump ring (30), make wing nut not only rotatable but also can not come off.The above has then constituted the lower part of open-close type saddle.Upper and lower two parts cooperate, but saddle just folding freely, thereby the obstacle when having got rid of the inflator operation of components reaches the purpose with the car inflation.

4, locate at the anterior inboard little rivet (32) of saddle support (31) near folder beam front end, load onto the little rivet (33) of a same specification in addition, make it after saddle opens, to prop up the front end of folder beam (34), the front portion of excessive damage saddle cover (car purchaser adds in addition) of neither can overturning, saddle top during inflation also can be avoided it to turn back backward and hinder operation.

The utility model compared with prior art has following excellent length:

One, very easy to use.When needing inflation, as long as unscrew purpose made wing nut in this device with hand, from behind saddle top is mentioned and upset forward, again the air guide sebific duct is taken out from handle and push rod, dial the little catch in the frame lower adaptor of changing trains or buses then left, the ozzle of air guide sebific duct rear end is tightened on the tapped air gate, can uses as common Floor Pump.With finishing, the air guide sebific duct is placed the original place, put down saddle top and wing nut is tightened (the slightly upwards arching of cross sill this moment, its elastic force can not get loose wing nut in driving; Simultaneously, two hollow bolts are strained to the centre, are made the upper and lower two parts of saddle in conjunction with firm), just rideable.Except that gas replenishment process, half a minute is once only used in operation.Indivedual persons of short and small stature if inconvenience firmly, then can be nearby easily by means of objects such as atural object such as road curb, little ditch, rut or brick, stone, wooden units.

Two, cost is very cheap.Because this device mainly is to utilize the transformation of the way of frame parts, only adds a spot of finding in addition, so compact conformation, technology is simple, and cost is very low, and than the Floor Pump of making same specification, every is reduced cost 1/3rd approximately.Particularly under the situation that the market steel are in short supply at home, produce the national conditions that this kind device is fit to China especially.

Three, light and handy use more.The bicycle of this device is housed, only increases deadweight 500 grams, so road speed is not had influence.The length overall that adds a part of saddle pipe because of seat tube is greater than the length of general Floor Pump stack shell, and uses small size leather cup, so brisk laborsaving when inflating, a hand just can be operated.It not only can give the gas injection of this car whenever and wherever possible, makes inside and outside tire exempt from also to can be inflations such as other bicycle and hand barrow, three-wheel vehicle and motor bike because of the tolerance deficiency causes improper damage.In addition, also can be loaded on the light-duty vehicles such as trishaw.

Four, firm attractive in appearance.This device does not have any destruction to the various holding capacity of bicycle, and can't integral body steal under the situation of instrument not having, and is safe and reliable.Its consumable accessory only has a leather cup, as long as unscrew the saddle pipe locknut during replacing, saddle is taken off from vehicle frame, just can operate.It exposes part and has only a little catch that nail is big, but places than the shelter, and is not fragile, and outward appearance is good.

Preferred forms of the present utility model is to be practiced midwifery by the bicycle special manufacturer.Can estimate that the new bicycle that this device is housed is with popular, even as for the upgraded product that is expected to become on the bicycle development history.Also can carry out the old bike repacking by small-sized repair plant and self-employed worker.In this way, provide great convenience not only can for hundreds of millions customers, bring good social benefit, and producer also will get ahead of others the acquisition considerable economic in intense market competition.
