Description

The disposable lighter inflator

The utility model belongs to the apparatus for filling of liquid gas, is applicable to the usefulness of giving the inflation of disposable lighter with cylinder for liquefied gas.

Be to process with turner with cylinder for liquefied gas to the capital equipment that disposable lighter charges liquefied gas at present, it comprises base, column and charge valve, charges liquefied gas by the charge valve that directly is fixed on lever one end to disposable lighter.Its shortcoming is: operation is many during manufacturing, the cost height, Heavy Weight, transportation inconvenience, in charging process because of can only on could inflate when arguing bar, stop during depress lever inflating, once do not note unclamping lever, liquefied gas will leak automatically, easy initiation fire is dangerous.

The purpose of this utility model is a design disposable lighter inflator a kind of in light weight, simple in structure, safe and convenient to use.

Task of the present utility model is finished as follows, it includes base, column and charge valve, it is characterized in that: two standing screws are arranged between the base of punching press or casting forming and the hollow column, screw rod also is fixed with a fixed head by nut simultaneously in the column upper end, the fixed head top is arranged with a movable pressing board in parallel, fixed head and movable pressing board at one end are connected with bearing pin by their link arm, the other end at movable pressing board is fixed with a charge valve with nut, charge valve top is for connecting the hose coupling of cylinder for liquefied gas, the bottom is the air tube to the disposable lighter inflation, having a hole near on the movable pressing board of charge valve, on the fixed head of hole below also correspondence have a hole, screw rod is housed in the hole, the screw rod nut, packing ring is fixed with a chuck, have on the chuck with air tube is corresponding and can block the bayonet socket that the lighter inflation is chewed, screw rod stretches out the activity of upper end parallel activity pressing plate and is connected with depression bar from the hole of movable pressing board, with this interface is that fulcrum is provided with a moving fulcrum at depression bar by, lining, be connected with the collar with depression bar on the moving fulcrum, following and fixed head is connected with a back-moving spring.Chuck can be a cross, and each end is provided with bayonet socket symmetrically, uses in order to replacing.

The utlity model has following advantage: because its critical piece all adopts punching press or die casting to make, other annex adopts standard component to assemble, it is simple in structure, in light weight, cost is low, transports, carries and use all very convenient, because of having utilized the principle of composite lever dexterously, become the formula inflation into the pressure type inflation, can not lose heart, increased security because of unclamping depression bar.

Fig. 2 is the plan structure schematic diagram of chuck of the present utility model;

Fig. 3 is the structural representation of charge valve.

Describe embodiment in detail below in conjunction with accompanying drawing, the utility model disposable lighter inflator, its critical piece all adopts punching press or casting forming, other annex adopts standard component, in the middle of base 1 and hollow column 2, there are two screw rods 3 fixing, screw rod 3 also is fixed with a fixed head 4 by nut simultaneously in column 2 upper ends, fixed head 4 tops are arranged with a movable pressing board 6 in parallel, fixed head 4 at one end connects with bearing pin 5 with the reinforcement link arm of movable pressing board 6 by them, the other end at movable pressing board 6 is fixed with a charge valve 11 with two nuts 13, charge valve 11 tops are for connecting the hose coupling 12 of cylinder for liquefied gas, the bottom is the air tube 14 to the disposable lighter inflation, having a hole near on the movable pressing board 6 of charge valve 11, on the fixed head 4 of hole below also correspondence have a hole, screw rod 10 is housed in the hole, two nuts 17 of screw rod 10 usefulness and packing ring are fixed with a chuck 16, have on the chuck 16 with the air tube 14 corresponding lighter that can block and inflate the bayonet socket of chewing 15, screw rod 10 stretches out the activity of upper end parallel activity pressing plate and is connected with a depression bar 7 from the hole of movable pressing board 6, with this interface is that fulcrum is provided with a moving fulcrum at depression bar 7 by the position, lining, connect with the depression bar 7 usefulness collars 9 on the moving fulcrum, be provided with a back-moving spring 8 down and between the fixed head 4.Chuck 16 can be a cross, and each end is provided with four bayonet sockets 15 symmetrically, uses in order to replacing.When giving disposable lighter topping up gasification, hose coupling 12 with flexible pipe on the cylinder joint and charge valve 11 tops is locked earlier, it is standby to open gas-filled switching tube, as long as the bayonet socket 15 that snaps on the chuck 16 is chewed in the inflation on the disposable lighter, depress depression bar 7, depression bar 7 moves down with the form drive charge valve 11 of composite lever, the inflation that makes air tube 14 aim at and compress on the lighter is chewed, air tube 14 overcomes to move on the pressure of the spring 20 in the charge valve 11 makes rubber cushion 18 leave core 19 on the air tube 14, and the liquefied gas in the steel cylinder just can enter in the air container of disposable lighter in charge valve.When unclamping depression bar 7, lever recovers original position under the effect of the back-moving spring 8 of moving fulcrum, the air tube 14 of charge valve 11 also retracts air tube 14 position that original rubber cushion 18 is sealed air tube core 19 under the effect of back-moving spring 20, do not have gas leak, reach the purpose of safety in production.When actual charging, be the mode that adopts pedal, promptly the end at depression bar 7 is a rope, rope is being hung with pedal near the place, ground, with the foot-operated hand that replaces.When inflation, be that cylinder for liquefied gas is being stood upside down in addition, charge into the liquid gas that is only in the lighter.
