Abstract

The utility model relates to an integral device of the inflation and the vehicle lock for the bicycle. The utility model is an improvement of the inflator and the vehicle lock structure of the bicycle. The device is a hand-operated inflator. The link mechanism of a hand crank makes a piston type air-pressing mechanism to compress the air, and is in screw thread fit with the head of the air nozzle of the bicycle tyre through the inner screw threads of a shielded air duct and an inflator-lock dual-purpose joint of an end air lock to inflate the bicycle. When the utility model is used as the bicycle lock, the air duct and passes through the spoke ribs of the bicycle tyre to fasten any other fixture, and the inflator-lock double-purpose joint is inserted into the lock hole of a locking head. The utility model has the advantages of one object with two purposes, labor saving in operating, convenient carrying, and hard stolen.

Description

Integral inflating, lock implement for bicycle

The utility model is the improvement to bicycle pump and Vehicle lock structure.

Existing bicycle pump and lock are separately manufacturings and use.Floor Pump adopts long tube type cylinder and long handle type piston, and oad is bigger, be difficult for carrying with car, and be being contained on the bicycle of having, also stolen easily.This Floor Pump is required great effort very much simultaneously, and Ms, children are not easy to operate.

The utility model purpose provides a kind of bicycle inflation, integrated lock device, and this inflator pump can be given Tyre inflating double as lock function again, dual-use material.Laborsaving during inflation, carry with car, be difficult for stolen.

The utility model is to realize like this, this device adopts the shaking inflator pump, it is that a cross-sectional plane is garden shape or ellipse garden shape cylinder, one piston crank mechanism is arranged at the top in the cylinder, small end and crank are hinged connection even, the connecting rod lower end combines as a whole by hinge and piston, the coaxial connection of handle that crank and cylinder are outer.Shake handle and rotate, make the crank drivening rod, force piston to move up and down in cylinder, the piston lower plane is being close to sealing rubber ring.Descent of piston, make the rubber seal pressurized air, when air pressure acquires a certain degree, will the steel ball of cylinder lower end outlet be backed down, gas slit around the steel ball enters the armouring ventilation flue, and the gas that the ventilation flue does not hold, the dual-purpose joint of lock and bicycle quick nausea are chewed to cooperate to bike tyre and inflated.

Because the ventilation flue is the India rubber tube that armouring or braided steel wire net surround, it has certain-length, can be used as the lock rope and uses.Like this gas do not held of ventilation flue, lock dual-purpose joint, there is negative thread its in-to-in inboard, can chew head with the bicycle quick nausea and cooperate.There is the dead bolt draw-in groove in the outside, also dual-purpose joint can be inserted in the tapered end lockhole of cylinder hypomere, and dead bolt is blocked, and has only the key of insertion just can open.

Accompanying drawing is illustrated:

When Fig. 1 gives the inflation of tire state for this device, its inner structure scheme drawing;

Its contour structures scheme drawing when Fig. 2 installs lock state for this.

Fig. 1,2, this device is the shaking inflator pump, the cross-sectional plane of cylinder (6) is garden shape or ellipse garden shape, piston crank mechanism is equipped with in the upper end in the cylinder, connecting rod (3) upper end is hinged connection even with crank (2), connecting rod (3) lower end and piston (4) are hinged and are connected as one, and crank (2) is coaxial the connection with cylinder (6) external handle (1).The lower plane of garden shape or ellipse garden shape piston (4) is connecting sealing rubber ring (5), and and certain interval arranged between the piston, piston (4) has induction opening (13), rubber ring (5) has induction opening (14), air in the two right title aperture and the certain distances that stagger, cylinder (6) is provided by cylinder balancing hole (15).Atmosphere is by cylinder balancing hole (15), and induction opening (13) and induction opening (14) are inflated in cylinder (6).When piston (4) is up, the seal ring (5) of piston (4) bottom is under cylinder wall friction force effect around it, make seal ring (5) and piston (4) certain distance that staggers, induction opening (13) is linked to each other with induction opening (14), and the air that enters cylinder balancing hole (15) like this will enter into following cylinder (6) inner chamber of seal ring (5).When piston passes through top dead point, piston enters compression stroke, rubber seal (5) is close to piston (4) lower plane again like this, induction opening (13) and induction opening (14) are stopped up, the following air of seal ring (5) in the cylinder (6) is compressed, pressure increases to a certain degree, cylinder (6) exit is installed steel ball (7) and is backed down, make support spring (10) compression under the steel ball (7), pressurized air flow in the ventilation flue (8) all around from steel ball (7) like this, when piston (4) reaches after bottom center, piston (4) begins to enter upstroke again under piston crank mechanism drives, spring (10) elongation at this moment makes steel ball (7) close outlet (12), like this on the piston (4), following back and forth movement supplies gas constantly for cylinder outlet bonded assembly ventilation flue (8) compression.

Ventilation flue (8) is the India rubber tube that is surrounded by armouring or braided steel wire net, and it has certain-length.Not holding ventilation flue (8) has the dual-purpose joint of gas lock (9), and there is negative thread the joint inboard, can chew head with the bicycle quick nausea and cooperate, inflates for bike tyre (21).Simultaneously, in the dual-purpose joint outside dead bolt draw-in groove (20) is arranged, the dual-purpose joint of this gas lock (9) can be inserted in the lockhole (17) of cylinder (6) lower surface (11) bonded assembly tapered end (16), makes dead bolt (19) block dead bolt draw-in groove (20), has only the key of insertion just can open.Ventilation flue (8) can be used as the use of lock rope again like this, this can be passed the bike tyre spoke, and bicycle and other fixtures lock together, and makes bicycle be difficult for theft.

Outer wall at cylinder (6) also has fastening annex (18), and the clip that it has fixed orifice is installed on the bicycle inflator pump, carries with car, and inflator pump is difficult for stolen again like this.Because adopt the inflation of shaking piston, very laborsaving, Ms, children, weakling also can use.

This handle can be collapsible, drawer type, also handle can be changed into belt pulley, sprocket wheel etc., and the type of drive that perhaps useful cycle chain drives reaches laborsaving purpose.

This shows this bicycle inflation, integrated lock device, it has inflation and lock function, and dual-use material is loved by people deeply, and rapid operation is easy to carry simultaneously, is difficult for advantages such as stolen.
