Abstract

The utility model discloses a portable theft-proof inflator for bicycle which is an inflating tool capable of being carried with the vehicle. The portable theft-proof inflator for bicycle is composed of a connection-pin piece which can assemble the inflator with a bicycle lock, and, a portable inflator. The portable theft-proof inflator for bicycle is characterized in that an upper connection-pin piece and a lower connection-pin piece, which adopt the dismount-proof structure, are fixed to the bicycle beam through fastening screws; besides, the upper connection-pin piece is provided with a lock which controls the telescoping of a movable chuck-head of the upper connection-pin piece, so that the lock of the portable inflator can be fixed between the upper connection-pin piece and the lower connection-pin piece. The handle of the portable inflator being detachable, the utility model has the advantages of convenience for carrying, and, convenient operation.

Description

Portable theftproof inflator for bicycle

The portable antitheft inflator of bicycle is a kind of air-inflating tools that can carry with car.

In the past we seen and recognize with the car Floor Pump, what have is non-anti-theft, what have makes as one inconvenience with bicycle, the inconvenience that has is used and is carried.So can not see on the market now anti-theft feature with the car Floor Pump.

The purpose of this utility model: be that will to design a kind of energy antitheft, be easy to carry, use again Floor Pump easily, and make also and want easily.

The utility model by last connection fastener (1), connect fastener (2) down, portable inflator (15) is formed.Antitheft in order to realize, when carrying, inflator is contained between the fastener of connection up and down of bicycle beam by lock.Take on last connection fastener, a lock to be housed,, reach antitheft purpose with stretching out and measure such as withdrawal of the movable chuck of its control on fastener.The handle of inflator is removable free handle, thus can be when using as common inflator, the both hands lever is exerted all one's effort downwards, and it is smaller to add the inflator diameter, so laborsaving.When carrying, handle can be pulled down again, and eye-splice reaches portable purpose so can resemble to be installed on the Inflator mounted on bicycle that we see on cross girders on the tracheae outer wall of inflator.

Wherein:, (1) goes up the connection fastener, (2) connect fastener down, (3) lock, (4) movable chuck, (5) tracheae of inflator, (6) piston set, (7) piston rod, (8) mother that performs, (9) inflator head, (10) free handle, (11) coupling nut, (12) inflate flexible pipe, (13) movable foot-operated, (14) damping rubber, (15) portable inflator, (16) bicycle car beam, (17) semicircle card-1-

Below in conjunction with details are as follows with embodiment shown in the accompanying drawing:

The fixedly ear that connects fastener (1) and (2) up and down upwarps about 45 °, is separately fixed at the above and below of cant beam before the bicycle by holding screw.When inflator (15) block be placed between connection fastener (1) and (2) after, the cap head of holding screw will be blocked by inflator, and can not dismantle.As shown in Figure 6.Under connect a fixed chuck arranged on the fastener (2).A movable chuck (4) is arranged on the last connection fastener (1), and it is locked (3) control and stretches out and regain.A unthreaded hole is arranged in the middle of the head of movable chuck (4).As shown in Figure 3.

The tracheae of inflator (5) bottom has a pit, side that the blind hole of give vent to anger a tapped bore and a dress movable foot-operated (13) is arranged, and on the pipe outer wall one and half garden cards is housed.Piston rod (7) is a upper end steel pipe interlinked with the outside, and the upper end is connected with inflator head (9).Inflator head (9) is a cup-shaped, and head is that half garden shape and centre have a logical tapped bore, and this hole communicates with the hole of piston rod (7).The end spiral shell head of flexible pipe (12) of inflating can join with the tapped bore of giving vent to anger of tracheae (5), and the other end is the movable screw female, can join with the bicycle valve.When carrying, can be hidden in the piston rod (7), but the movable screw female is exposed at the outside of inflator head (9).Free handle (10) is a microscler semicircle pipe, and there is boss the centre and a via hole is arranged.As shown in Figure 5.When inflator carried with car, free handle was buckled on the outer wall of tracheae (5), and an end is entangled by inflator head (9), and an end is inserted in the half garden card of tracheae (5).The pit of tracheae (5) bottom is inserted in down on the fixed chuck that connects fastener (2).Coupling nut's (11) one ends be exposed at inflator head (9) outer inflate flexible pipe (12) the traveling nut headgear together, the other end is inserted in the unthreaded hole of the movable chuck (4) that stretches out.The movable chuck that stretches out (4) is pinned by lock (3) again.So just the inflator lock is contained on the bicycle.Referring to Fig. 1, Fig. 3, shown in Figure 4.

In the time of need inflating, take off the order with load onto opposite.At first extract out and inflate flexible pipe (12), be connected between inflator and the bicycle valve.Draw back inflator head (9), take off free handle (10), be fixed on the inflator head (9) by coupling nut (11) then, pin steps down in the activity of opening foot-operated (13) and goes up just can resemble and use the common Floor Pump.Referring to shown in Figure 2

Claims

1, a kind of bicycle pump, this inflator is characterized in that by be fixed on go up connecting fastener (1), connect fastener (2) and can lock the portable inflator (15) that is contained between the upper and lower connection fastener and form down on the bicycle car beam by holding screw:

A, being equipped with one at the axial location of last connection fastener (1) can axially movable cylindricality movable chuck (4), this movable chuck by on the horizontal position of last connection fastener (1) one have the cylinder locks (3) of short slot to control its axially activity;
