Abstract
The utility model relates to the improvement of the existing bicycle inflator, particularly to a multipurpose hand inflator. The utility model has the advantages of labour saving and multiple purposes, and the inflator is operated by a hand in an automatic return mode. The inflating purpose is achieved by the fact that a piston with an 'O'-shaped sealing ring repeatedly moves in a canister body. An inner hole of the canister body and an air outlet nozzle are connected by a reducing pipe. A working surface is pushed by the conic piston to fit with a reducing section of the reducing pipe, and thus the purpose of labour saving is achieved. The working travel of the inflator is 8 to 9cm. The utility model has the advantages of small volume, portability and wide application. The utility model is provided with an air outlet nozzle with a standard thread buckle, and is connected with four kinds of joints conveniently.
Description
The utility model relates to the improvement to existing bicycle pump structure.
Existing bicycle pump is to do axial perseveration by the piston of being furnished with " O " RunddichtringO at the cylindrical shell endoporus to reach the inflation purpose.Its cylindrical shell endoporus adopts the sudden contraction pipe to be connected with the air outlet.During work, because flow area dwindles suddenly, local resistance is big, causes the piston propelling force big, needs both hands to advance.Existing pump piston propulsioning face is the plane, and during work, what compressed-air actuated rebounding force can not be more concentrates on " O " RunddichtringO, after the wearing and tearing of " O " RunddichtringO, influences its sealing effect.Existing pump air outlet is to be connected with the clamp type link by flexible pipe with the bike tire valve cock, the poor reliability of linking.Simultaneously also make its purposes single.Existing pump piston stroke is long, and cylindrical shell is long, and inconvenience is carried.
The utility model takes to reduce propelling force in order to overcome above-mentioned deficiency; Shorten piston stroke and the structural design that can be connected multiple joint, made effective laborsaving, portable, multiduty pump of holding.
The utility model is as shown in Figure 1: cylindrical shell (1) endoporus is placed the piston body (4) that " O " RunddichtringO (6) is housed, and this piston body links the stopper rod of taking over a job (5) with rib-loop.Cylindrical shell bonnet (2) hole is passed piston rod and is buckled with cylindrical shell with rib-loop and be connected.Spring (8) is through on the piston rod, and handle (9) is buckled with piston rod with rib-loop and is connected.(7) be gas port, (3) are the cylindrical shell outlet nozzle.
Fig. 2 is the left view of Fig. 1.Expression: cylindrical shell (1) is concentric with outlet nozzle (3).Cylindrical shell bonnet (2) is held the place and is equated with handle (9) width.
The utility model cylindrical shell endoporus adopts reducing pipe to be connected with the air outlet.Piston taper propulsioning face can coincide with the converging transition of reducing pipe.One radial groove is arranged on the piston body, and " O " RunddichtringO is put also can be movable vertically in groove in this groove.When handle promoted the Piston Compression air by piston rod, compressed air divided rapidly on piston taper working surface that interporal lacuna acts on " O " RunddichtringO in two gas ports at the piston edge of flowing through and piston body external diameter and the cylindrical shell.Owing to be compressed the shunting of air, " O " RunddichtringO is subjected to the extruding of bigger power all the time in piston advances, even under the situation that " O " RunddichtringO is worn, also can guarantee sealing effect.Realized the validity of inflating.After this, under the effect of spring, piston is returned to end of travel.Meanwhile, ambient air is by the gap in piston rod and cylindrical shell bonnet hole, and through the gap of piston and cylindrical shell endoporus and the gap of " O " RunddichtringO and piston radial bottom land, two gas ports on piston body enter the air compression chamber and wait to press.
When said structure made the Piston Compression air, local resistance reduced, thereby had reduced the propelling force of piston.Under the mode of holding was inflated effortless condition, the utility model adopted big as far as possible piston cross-section diameter, to increase the volume in air compression chamber, reduced piston and advanced number of times, finished to inflate requirement.Through experiment, the piston cross-section diameter for well, has reached the labour-saving purpose with 1.8cm-2cm.
The mode of holding that the utility model takes a hand to inflate is worked, thereby has determined that the short ability of pump stroke is easy to use.Through experiment, piston stroke with 8-9cm for well.The utility model length overall is no more than 20cm, and decreased food is no more than 10cm, has reached portable purpose.
The utility model cylindrical shell outlet nozzle external diameter adopts the standard rib-loop, but has the multiple joint convenient assembling and disassembling of corresponding rib-loop, and this pump is served many purposes.
Shown in figure (3): through hole cone joint (10) is connected with cylindrical shell (1) rib-loop.Can inflate to the different inflatable substrate of various air inlet bores.
Fig. 4 is the left view of Fig. 3.Expression: behind through hole cone joint (10) screw-in and the cylindrical shell (1), the two is concentric.
As shown in Figure 5: a flexible pipe (12) two ends are connected with joint (11), joint (13) drive fit respectively.Joint (11) rib-loop connects cylindrical shell (1).Screwing in bike tire's valve cock with joint (13) can inflate to bicycle.
Fig. 6 is the left view of Fig. 5.Expression: joint (11), joint (13), cylindrical shell (1) are located wall and all are garden shape.
As shown in Figure 7: a kind of tubaeform cover cap (14) is connected with cylindrical shell (1) rib-loop.Is furnished with flexible pipe (15) in this cover cap.The mouth of a river under inserting flexible pipe in the civilian pond of stopping up, cover cap covers down the mouth of a river, inflates with the utility model, and the air-flow that has pressure is washed obstruction or go out open the slit, can play the effect of dredging pipeline.
Fig. 8 is the left view of Fig. 7.Expression: flexible pipe (15) is arranged in cover cap in the heart.
Shown in figure (9): minor diameter one end of the air tube of the row of being applicable to, orchid, football (17) soft joint (16) in inserting, carry out drive fit.Joint (16) is screwed in cylindrical shell (1) can inflate with orchid, row, football to playday.
Figure 10 is the left view of Fig. 9.Expression: joint (16), air tube (17) and cylindrical shell (1) are connected the back with one heart.
Claims (1)
- A pump of forming by cylindrical shell (1), piston body (4), " O " RunddichtringO (6), piston rod (5), cylindrical shell bonnet (2), spring (8), handle (9), gas port (7), cylindrical shell air outlet (3).It is characterized in that cylindrical shell endoporus and air outlet employing reducing pipe is connected, the converging transition coupling of piston taper propulsioning face and this reducing pipe.
