Description

Bike tyre make things convenient for inflator pump

Affiliated technical field:

The utility model relates to the inflatable tool of bike tyre, is a kind of inflator that makes things convenient for that is arranged in the vehicle frame.

Background technology:

The Regular Bicycle tire often need be inflated with inflator pump, particularly uses tire more long afterwards, usually results in hand cramps to people because jogging gas.For this reason, attach on the cycle frame that has inflator pump is arranged.Like this, though can make things convenient for use, long inflator has not only occupied the limited space of bicycle, and inflator is stolen easily.

Summary of the invention:

The purpose of this utility model is to overcome the shortcoming of prior art, and a kind of inflator pump that makes things convenient for of bike tyre is provided, and it is arranged on the inflator pump of general structure in the vertical tube of bicycle dexterously, not only made things convenient for use, and inflator pump is difficult for stolen.

For achieving the above object, the utility model provides a kind of inflator pump that makes things convenient for of bike tyre, comprise: cylindrical shell, piston, pull bar, handle, flexible pipe, its cylindrical shell was made up of tube head, stack shell, the tube end, and with being threaded, an end is the end socket shape to stack shell at the end with tube head, tube, sidewall is provided with the tapped bore of connection hose, barrel jacket is contained in the vertical beam pipe of bicycle, and the tube end is positioned at vertical beam pipe bottom, offers the air extractor vent of a connection hose on the vertical beam pipe corresponding to tapped bore; Handle is a short tube type, and a hinged and rotatable back, the upper end of it and pull bar and a tube headgear close; Handle place bike saddle below, and fastening with bike saddle.Described short tube type handle is provided with hinge at the short tube middle part, has notch from the middle part along pipe range on the short tube sidewall, the tubular type handle can be revolved around hinge turn 90 degrees, with the tube head fit.Described bike saddle is to be fastened on the handle that closes with the tube headgear with fly nut by clip.

The utility model compared with prior art since the inflator structure that adopted the Floor Pump with common is identical basically, just with the inflator diameter according to the design of standpipe of bicycle internal diameter, diameter is littler, but the length lengthening, therefore, tolerance does not reduce.Because inflator is placed in the vehicle frame vertical tube, and be the short tube types of rotatable 90 degree with handle design, offer the air extractor vent of a connection hose in the vertical tube bottom, therefore, when needs are given inflation of tire, in the tapped bore at the bottom of hose coupling is screwed into tin, connect the inflation of tire inlet, only need then the fly nut below the vehicle seat is unclamped, removed vehicle seat, handle is mentioned, revolved and turn 90 degrees, can press handle up and down, give inflation of tire.The utlity model has reasonable in design, easy to use, be difficult for advantages such as stolen.
