Description

Fixing type theft-proof high-pressure

The utility model is applicable to that bicycle, trishaw make inflatable tool and use.

In the prior art, the single tube Floor Pump that carries with car only, suction quantity is few, and efficient is low, and is fragile, and inconvenience is easily lost.

The purpose of this utility model is: design a kind of can being integral with vehicle frame, anti-theft is strong, easy and simple to handle, again can be high-pressure aerated, the air-inflating tools of high efficiency, rainproof, laborsaving, no leak, long service life.

The antitheft high-pressure pump of fixed type of the present utility model is made up of pipe, cross bolt, stage clip, rubber spool, piston, piston, obturator piston ring, end socket outer tube, antitheft snap ring, universal base, cardan pin, antitheft nail, fixation clamp etc. in tire tube valve, rubber pad, mouth cap, joint cap, corrugated hose, joint, the end socket.Piston is a garden shape, and its middle part, outer garden is a cone, with the conelet end that joins be Cylinder, the half-blindness hole of (φ 1～φ a 8) mm is arranged, and tangent with little conehead on the post of garden, in the outer face axial line central authorities of Cylinder hole, a garden is arranged.Joining an end also for Cylinder with auger, and auger and Cylinder joint are the angles, garden of mm of a R1～R4), and it is a garden male screw body that the other end of Cylinder joins.There is an internal thread hole in axle center central authorities at garden male screw body, and communicate with hole, garden, piston other end axle center.

Piston adopts metal or non-metallic material to make.The external diameter of obturator piston ring is than big (0.1～2) mm of internal diameter of end socket outer tube, and its internal diameter is than big conehead footpath little (0.1～3) mm of piston, and seal ring adopts the oil resistant antifriction rubber to make.Pipe is hollow tubular in the end socket.The one end is a garden shape enclosed shape, and (tapped through hole of mm of M5～M8), the other end are flat mouthful, are processed with the long fine thread of (5～15) mm on its inwall to have one in its axle center central authorities.The end socket outer tube is a hollow tubular, and an end is a reducing garden shape enclosed shape, and the other end has a groove for flat mouthful on its internal diameter, and pipe and end socket outer tube all can adopt metal or non-metallic material to make in uniform 4 through holes around the channel bottom, end socket.Universal base is an oblong, and its end face is a spill, in spill axis central authorities hole, a garden is arranged.Cardan pin is made up of two reducing Cylinders and a cuboid, and a through hole is arranged in the side of cuboid.

The utility model compared with prior art, its advantage is: can fuse with vehicle frame, can be antitheft, rainproof, can be high-pressure aerated, high efficiency, no leak, long service life, easy and simple to handle.

Below in conjunction with description of drawings embodiment.

See Figure 12.Mouth cap (3) is inserted on tire tube valve (1) large-diameter, rubber pad (2) is enclosed within on the small axle diameter of tire tube valve (1), two ends with bellows (5) put joint cap (4) again, tire tube valve (1) large-diameter one end is inserted in bellows (5) the one end pipes, with utensil joint cap (4) is pushed, make tire tube valve (1), corrugated hose (5), joint cap (4) are close to together.An end that again joint (6) is had a thread rod inserts in the other end pipe of corrugated hose (5) outwardly, with its joint cap (4) extruding, it is tightly connected with utensil.With the core print of rubber spool (10) outwardly, be enclosed within on the stage clip (9) again, and in the threaded hole of piston (11) of packing into together, the cross recessed one side arranged inwardly, be screwed in the axis hole screw thread of piston (11), it is tightened with cross bolt (8).Again that cardan pin (18) belt length is a square end inserts in the Qi Yuan hole from the direction of universal base (17) band groove, the bipod of groove abuts against the interior pipe of end socket (7) band garden shape and seals on the external diameter of an end, and welding (or bonding) is integral, and more antitheft snap ring (16) is enclosed within on the external diameter of pipe (7) in the end socket.After the threaded end of piston (11) external diameter coated sealant, be screwed in the end socket in pipe (7) negative thread, obturator piston ring (12) is enclosed within on the cone of piston (11).Coat lubricating oil again on the inwall with end socket outer tube (13) and be sleeved on outside obturator piston ring (12), piston (11), the interior pipe of end socket (7), with utensil antitheft jump ring (16) is sent in end socket outer tube (13) the pipe internal channel again.Four uniform through holes of groove bottom are to be convenient to utensil to get antitheft jump ring (16) usefulness.End socket outer tube (13) can be managed (7), piston (11), obturator piston ring (12) outside back and forth movement in end socket.On the thread rod of joint (6), coat sealant, be screwed in the end socket and manage in the shape end socket central, threaded hole, (7) garden.Again the cardan pin (18) on the pipe (7) in the end socket is inserted the centre of two fixation clamps (20), riveted tightly after tightening with anti-theft screw (19).Two fixation clamps (20) are the fixed positions that is welded on the vehicle frame.Two small size clamps (14) large size clamps (15) are enclosed within respectively on the vehicle frame, are used for clamping the antitheft high-pressure pump of fixed type.

When tire need be inflated, corrugated hose (5) is taken off from small size clamp (14), tire tube valve (1) is aimed at the tire valve inside, mouth cap (3) is screwed on the screw rod of valve inside, take off inflator from large size clamp (15) then, inflator can be transferred direction arbitrarily.End socket outer tube (13) is upwards mentioned, obturator piston ring (12) falls into piston (11) conelet bottom, enter in the end socket outer tube (13) the half-blindness hole of air from piston (11), when antitheft jump ring (16) touches piston (11) by the Cylinder end face of screw thread one end, air-breathing stopping.When pressing down, gas is washed the endoporus of rubber spool (10) compression spring (9) by cross bolt (10) open with end socket outer tube (13), pipe (7), joint (6) in the end socket, and corrugated hose (5) enters the inner tube of a tyre.When the batt joint of end socket outer tube (13) touched universal base (17), downward motion stopped.Pressure-raising end socket outer tube (13) is till the required air pressure of tire so repeatedly.Because of a valve is respectively arranged on piston (11) and the tire, so energy stored-gas in the interior pipe of end socket (7) pipe after continuous air inlet, can produce than anticyclonic pressure, make high efficiency, laborsaving.After having inflated, inflator can be leaned against large size clamp (15) trough and fix, again corrugated hose (5) be unloaded from tire, fixing by being placed in small size clamp (14) groove.
