Description

Double-tube inflator capable of being fixed on bicycle

The utility model is the double-barreled pump that can be fixed on the bicycle, also is applicable to the inflation of tires such as tricycle, motorcycle, and it belongs to the assistant product of people's daily life.

Known bicycle inflator is more, and immediate by its technical spirit is the plain edition high-pressure pump of selling on the market.It is by the single tube inflator, single piston guide rod, and fixed handle, cylinder, pneumatic tube are formed.The single tube inflator comprises loam cake and lower bottom base again, and piston guide rod comprises the perforation leather cup, steel compressing tablet and packing ring, nut, guide rod stake and coaxial springs, and cylinder is by air chamber and unidirectional spring valve.Thereby promote the upper and lower motion that the upper and lower action of a handle drives piston during work, carry out air-breathing compression, inflation work, pressurized air enters cylinder from one-way valve, air-breathingly enters tracheae from the perforation leather cup.When the pressure in the air chamber during greater than the elastic force of gas outlet valve, high-pressure air reaches the purpose of inflation just from pneumatic tube output.

Because known common high-pressure pump belongs to the single tube gas-filled type, so volume is bigger, carries inconvenience, must place ground when using simultaneously, both hands pressure-raising one was both required great effort piston guide rod, and operation is inconvenient again.

Task of the present utility model just provides a kind of double-barreled pump that is fixed on the bicycle, it is had with car carry, and inflation pressure is big, and is easy to use, and firm applied range is installed.

Task of the present utility model is finished as follows, adopts and settles two inflators on the little air reservoir of a horizontal type, in the tube two piston guide rods is set respectively, two piston guide rods are synchronously fixing with connecting plate, connecting plate is riveted mutually with lever handle, disposes backup plate again, and parts such as pneumatic tube are formed jointly.Wherein the little air reservoir of horizontal type is made up of air chamber and unidirectional spring suction valve and unidirectional spring gas outlet valve; Little inflator is by bobbin, upper and lower sealing sleeve, and upper and lower setting sleeve, center clamping screw rod, nut are formed; Piston guide rod is by leather cup, and steel compressing tablet, pad, nut, guide rod post are formed; Connecting plate is made up of connecting plate, pad, nut; Lever handle by two can take off folding handle, retaining pin module, two foldable support flap, the collar, steering knuckle are formed; Backup plate is made up of upper and lower backup plate, locking.Wherein retaining pin module is fixed on an end that leans on connecting plate on the handle, form by bayonet lock, grip block, fulcrum, bullet cover, another handle is being opened a pin-and-hole by connecting plate one end, two foldable support flap rivetings, it is fixing that the collar is straight, a support plate is riveted with following backup plate, and the other end of another root support plate is connected with handle by steering knuckle, but constitutes the lever handle of the application of force.

Carry two during use and can take off the folding handle, press down grip block bullet cover end on one side, be inserted in after allowing bayonet lock aim at the pin-and-hole of another root handle, handle is straight, then the collar is inserted in the joint of two foldable support flap, cause vertical support, form lever handle, power arm with a upper and lower motion lever handle of hand, connecting plate is also along with driving two piston guide rod motions, form two-tube upper and lowerly together, that double-tube inflator carries out simultaneously is air-breathing, compression, inflation action, pressurized air enter pneumatic tire by pneumatic tube, reaches the inflation purpose.

The utlity model has and carry lightly, compact structure is owing to adopt the fixing device of backup plate form, be difficult for becoming flexible in the driving way, need not place ground again during inflation work, add the lever handle of using lever principle, the application of force is light, one-handed operation, and air pressure can reach 7.5kg/cm ²More than.Simultaneously with become car supporting elegant in appearance.

Fig. 1 is for being fixed on the plan view of the double-barreled pump on the bicycle.

Fig. 2 is for being fixed on the side view of the double-barreled pump on the bicycle.

Fig. 3 is the partial view of retaining pin module on the lever handle that can be fixed on the double-barreled pump on the bicycle.

Below in conjunction with accompanying drawing full model utility is further described:

With reference to Fig. 1, Fig. 2: air reservoir (9) is equipped with unidirectional spring suction valve (22), scyewed joint, and spring gas outlet valve (10) is housed between the pneumatic tube (11); Two inflators have socket (5), on seal (18), lower sealing (7), on locate cage plate (17), locate cage plate (8) down, upper and lower setting sleeve is connect fastening by center clamping screw rod (18), nut (14); An end is equipped with leather cup formula piston (21) in the tube of piston guide rod (20), the other end and connecting plate (14) are fixed with nut, lever handle (13) is set on connecting plate (14), adopt pivot pin (15) hinged, lever handle (13) can take off folding handle (12) by two, (2) form, cooperate the location to make the bayonet lock on the handle (12) cooperate the location by the bayonet lock that takes off on the folding handle (12) with the pin-and-hole that another root takes off on the folding handle (2) with the pin-and-hole that another root takes off on the folding handle (2), make handle straight, be connected with collapsible location piece (3) with steering knuckle (1) at the other end that takes off folding handle (2), and two collapsible location pieces (3), (6) riveting of living between is equipped with the straight fixedly formation of the collar (4) fulcrum again, the lower end of collapsible location piece (6) connects with following backup plate (26) to be fixed, and forms lever handle (13).Backup plate is divided into backup plate (24) again, following backup plate (26), goes up locking strap (23) locking strap (25) down, and setting sleeve (8) welding is fixing down with last setting sleeve (17) respectively.

With reference to Fig. 3, in can take off the partial view of folding handle (2) (12) retaining pin module when straight, retaining pin module is by bayonet lock (27), grip block (28), fulcrum (29), spring (30) is formed.

Its member mostly adopts metal to constitute during manufacturing, air reservoir (9) wherein, take off folding handle (2), (12) and can adopt forming tubular product, on seal (18), lower sealing (7), last setting sleeve (17), following setting sleeve (8), are gone up backup plate (24) at connecting plate (14), down by the principal columns of a hall (26) but all punching press is in full bloom, join some standard piece and a small amount of machining again, decorate processing and just can finish.

During use locking strap is locked on the vehicle frame pipe of bicycle up and down, install air delivery device, a portable active handle (12) then, mother refers to the bullet cover position (38) of grip block in the depresses detent assembly (28), make and loosen mother behind the pin-and-hole on bayonet lock (27) alignment handle (2) and refer to, bayonet lock (27) enters the straight or Fig. 1 form of pin-and-hole handle, vertical foldable support flap (3) (6), allow the collar (4) fix and form fulcrum, carry on the afterbody of active handle (12), following motion, village's air that contracts just enters air reservoir (9) and achieves the goal by the tire that pneumatic tube enters required inflation then from inflator (5).Finish using,, can take off just folding down of folding handle (2), (12), be in the form of taking as long as bayonet lock (27) is broken away from pin-and-hole.
