Abstract

A lock inflator comprises an inflator, a trachea, a socket, a vent locking whip and a wrench, characterized in that the inflator socket which is double as the socket of the lock body is connected with the bottom of the air reservoir, wherein the upper end of the air reservoir is connected with an inlet plug, and the upper end of the inlet inflator with the lower end of the inlet inflator being connected with a chassis jacketed on the air reservoir is connected with a handle. A steel cable and a venting rubber hose are arranged in the flexible pipe with both ends of the flexible pipe being respectively fixed with an air outlet nozzle and a fillister of the connector, and a suction nozzle and a fillister on the air inflation lock. A drag hook is connected with a casing pipe with the inside of the casing pipe being equipped with a venting locking bar and a spring fixed by screw nuts, also the locking bar head is fixed on the side of the lock bar by a locking cap. Employing the drag hook mode of the design which is easier and more flexible to fix a valve cock applies to the two valve cocks, wherein the protective wrench arranged under the socket can also be a temporary vehicle repairing tool. The assembling design of the lock and the inflator has the advantages of being attractive, practical, ingenious, compact, and convenient to install, also low in price.

Description

The locking-type inflator

Technical field

The utility model relates to a kind of lock, especially a kind of locking-type inflator that integrates inflation, lock car, three kinds of functions of instrument.

Background technique

Bicycle is the means of transportation of extensively popularizing, and in order to strengthen anti-theft effect, the lock on rear wheel frame, generally also is equipped with long steel rope lock or Steel chain lock, is used for car and fixture bolt together.Yet, the rubber inner tube of bicycle often because of temperature change or by hard thing puncture become flat, the flat phenomenon of tire, need inflate with inflator, but gas finding tube inconvenience sometimes outside by bike, this is the trouble that the cyclist can run into.

Summary of the invention

The purpose of this utility model provides a kind of locking-type inflator, integrates inflation, lock car, three kinds of functions of instrument, and is both artistic and practical, easy for installation.

The design's locking-type inflator, comprise inflator, tracheae, base, ventilation lock whip and spanner, it is characterized in that the inflator seat again the base of double as lock body is communicated with connection inlet valve on the gas receiver with the gas receiver lower end, the air induction mast upper end connects handle, and the air induction mast lower end connects with the chassis that is enclosed within on the gas receiver; Wire rope and ventilating glue tube are in flexible pipe, and two ends are fixed with the outlet nozzle of connecting body and air inlet nozzle and the groove on groove and the inflation tapered end respectively; The drag hook adapter sleeve has ventilation locking bar, spring in the sleeve pipe, fixed by nut, and lock rod head is fixed on the locking bar end by lock nut.

This locking-type inflator, change fixed valve cock with iron clamp in the past during inflation, because of iron clamp can only be fixed a kind of valve cock, and had the valve cock of plunger also need mix corresponding mouthpiece to another kind.And the fixing valve cock of the drag hook mode that adopts the design all is suitable for two kinds of valve cocks, and is more apparent free and relaxed.The protection spanner that base is equipped with down also can be used as interim car repair tool.The Combination Design of this lock and inflator has possessed both artistic and practical, agile exquisiteness, advantage cheap, easy for installation, that carry with car.

Embodiment

The design's locking-type inflator is seen Fig. 1: comprise inflator, tracheae, base, ventilation lock whip and spanner, it is characterized in that gas receiver 4 lower ends and glue moulds flexible pipe 8 lower ends and be communicated with on the base 11 of double as lock body again at the inflator seat by connecting body 7; Gas receiver 4 upper ends are installed into vent plug 12, its plastics holder cap 16 and gas receiver 4 inwalls gummed, and gas receiver 4 is in lining sleeve pipe 3, metal jacket pipe 2 is arranged outward, as 3 top closure of sleeve pipe in the air induction mast, the plastic top screw thread combines with handle 1, and outer sleeve 2 is screwed with foundation ring 46.Wire rope 19 two ends are compressed with aluminium ring 22,35, and glue is moulded pipe 8 sebific duct 18 and wire rope 19 is nested together, and constitutes to lock whip; Referring to Fig. 4, Fig. 5: wire rope 19 and sebific duct 18 two ends are connected with groove 21 with the air inlet nozzle 20 of the outlet nozzle 33 of connecting body 7 and groove 34, inflation tapered end respectively, sheathed casing 6, sheathed casing 5 are enclosed within respectively and connect outside tapered end and the inflation tapered end, are fixed on rivet hole 36,23 places by rivet; Drag hook 32 rivetings are enclosed within sleeve pipe 24 on the locking bar 27 of ventilating with air inlet nozzle at sleeve pipe 24 lower end rivet holes 30 places, push spring 25, nut 26, rubber cushion 29, lock rod head 28, screw lock nut 9.Lock rod head 28 centers are exhaust nozzles 31.

The structure of base is seen Fig. 2: lock core port 10 is arranged on the base 11, lock core is mounted in it; Connecting head 37 puts cushion rubber and is communicated with 40 screw threads of the air outlet on the base, more than is the combination that whip is locked in base and ventilation.Suction port 39 puts cushion rubber with the gummed sealing of gas receiver 4 lower ends, and outer sleeve 2 is enclosed within gas receiver 4, lining sleeve pipe 3 outsides, and joins with chassis 46, uses bolt.Fore shaft 38 and air outlet 40 are arranged.The air inlet nozzle 39 that is with cushion rubber is integral with base 11, opposite side has the fixing clamp 47 of fixing this inflator, for one slotting pull 43 and eye pull 42 stage casings and present convex body 45, the gap fluted 41 between fore shaft 38 and air outlet 40, its shape is identical with convex body 45, but back-up wrench.Insert to pull and also have screw-driver 44 on 43.This inflator can be installed in bicycle back rest below with fixing clamp 47 and screw.

The structure of inlet valve 12 is seen Fig. 3: there are cushion rubber groove 13, rubber cushion 14 in inlet valve 12 lower ends, and the built-in rubber thimble 15 of ventilating hole combines with holder cap 16 screws, and there is vent 17 inlet valve 12 lower ends, make piston become live body.
