Abstract
The utility model relates to a bidirectional air inflation pump which is composed of an air pump, a piston rod, a piston, an end cover provided with a vent hole, a one-way valve, an air pipe, a guide rod connected to the piston rod and two connecting rods movably connected to the air pump, wherein a guide slot is formed on the air pump, and the guide rod penetrates through the guide slot and is movably connected to the two connecting rods. The bidirectional air inflation pump has the advantages of simple structure, labour saving, small size and portability.
Description
The utility model relates to a kind of hand air pump that is used for inflating tyres of vehicles.
Existing bidirectional inflating tube has No. 92228967 described hand-pulling type bidirectional pump tubes of Chinese patent, the pull handle that its structure mainly constitutes by cylindrical shell, top cover, bottom, by hollow round bar and holding assembly, first, second piston that is articulated on the pull handle are formed, wherein on the round bar of first, second piston space, have pore, between top cover and inflator, be equipped with one-way valve between bottom and inflator, its working principle is that air enters inflator from top cover, bottom, and the air after the compression is discharged by the hollow round bar by piston.Though this hand-pulling type bidirectional pump tube is than unidirectional pump efficient height, complex structure pulls and inflates effort.
The purpose of this utility model is to overcome above-mentioned deficiency and a kind of simple in structure, labour-saving bidirectional pump tube is provided.
The utility model is realized by adopting two connecting rods to drive piston rod, its structure is except that including inflator, piston rod, piston, the end cap that has exhaust port, one-way valve, tracheae, also include the guide rod that is connected on the piston rod, be actively socketed on two connecting rods on the inflator, wherein have guide groove on inflator, guide rod passes guide groove and two connecting rod loose joints.
The utility model adopts two connecting rods to inflate, and is not only laborsaving, and two connecting rods from guide rod separate folding after, bidirectional inflating tube overall volume is little, is easy to carry, and compared with the prior art, has characteristics simple in structure, easy to manufacture, easy to use.
Fig. 1 is an organigram of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
Now in conjunction with the accompanying drawings and embodiments the utility model is described in further detail:
Among Fig. 1, Fig. 2, end cap, 6 one-way valves, 7 guide rods, 8 two connecting rods, 9 that 1 inflator, 2 guide grooves, 3 piston rods, 4 pistons, 5 have an exhaust port have sealing cover, 10 seal rings, 11 tracheaes of pore 12.
As shown in Figure 1 and Figure 2, the utility model mainly is made of inflator 1, piston rod 3, piston 4, the end cap 5 that has exhaust port, one-way valve 6, tracheae 11, laborsaving in order to inflate, on piston rod 3, be connected with guide rod 7, loose joint has two connecting rods 8 on the end cap that has exhaust port 5 of inflator 1, on inflator 1, have guide groove 2, guide rod 7 passes guide groove 2 and 8 loose joints of two connecting rods, for anti-sealing enters in the inflator 1 by guide groove 2, on guide groove 2, be provided with the sealing cover 9 that has pore 12, have the sealing cover 9 of pore 12 and the junction point of guide rod 7 and be provided with seal ring 10.When using the utility model, swing two connecting rods 8, drive the action that inflation is finished in pistons 4 motions by guide rod 7, piston rod 3, time spent not, again two connecting rods 8 are separated with guide rod 7 folding, to be convenient for carrying.
Claims (2)
1, a kind of bidirectional inflating tube, comprise inflator, piston rod, piston, the end cap that has exhaust port, one-way valve, tracheae, it is characterized in that on piston rod, being connected with guide rod that loose joint has two connecting rods on inflator, have guide groove on inflator, guide rod passes guide groove and two connecting rod loose joints.
