Description
Technical field
The present invention mainly discloses the pump of a kind of pressure gauge at handle, refers in particular to a kind of manually disappointing pump that pressure gauge is made zero that need not.
Background technique
Pressure gauge is located at handle and has the advantage that reads pressure value easily, but traditional pressure gauge of being located at handle need be provided with outlet valve at handbar, needs after operator's aeration manually to lose heart, and manometric numerical value is made zero.
With reference to Fig. 8, schematic representation for the pressure display unit of existing bicycle pump, it mainly is by makers-ups of institute such as watchcase 91, instrument panel 92, pointer 93, connecting rod 94, central siphon 95, spring 96, outlet valve 97 and handgrip bodies 98, wherein this watchcase 91 is the transparent body, is covered on handgrip body 98 end faces outside the instrument panel 92; Wherein this pointer 93 floats on the scale of instrument panel 92, with its connecting rod 94 move forward and backward and left and right sides slippage; Wherein these central siphon 95 internal diameters place the connecting rod 94 of a winding spring, and this connecting rod 94 front ends linking has a pipe close 99; Wherein be provided with one in this outlet valve 97 and push knob 100 to push at any time to discharge the former gas that fills in the handgrip body 98 gas cabin path 10s 1; Wherein this handgrip body 98 is the handgrip of pump, but is provided with gas cabin path 10 1 in it, can unidirectional inflow be same as the gas of air-inflating tube flow pressure.
But, existing design is provided with an one-way cock between pump and air-inflating tube, also be provided with an one-way cock at inflator central siphon end, and the end at the handgrip body need be provided with an outlet valve, and in other words, existing design is provided with two one-way cocks and an outlet valve altogether, and after inflating, the operator gas must be released via outlet valve, the gas that order is filled in pressure gauge releases fully, if the operator has omitted the step of losing heart, pressure gauge shows wrong force value in the time of will making inflate next time.Moreover, though only needing careful note to inflate afterwards gas to be released promptly, the operator can exempt this disappearance, but, the design that this needs lose heart also can't obtain operator's favor, the operator wishes to obtain a kind of simple, easy mode of operation, therefore, existing design has the necessity that is improved.The problem that hope is got rid of by the present invention or alleviated Prior Art at least and met with.
Summary of the invention
Pressure gauge of the present invention is at the pump of handle, and the technical problem that institute's desire solves is that existing pressure gauge does not have the design of auto zero, and the operator must careful note manually lose heart, and existing design can't be satisfied operator's expectation really, and remains to be improved.The invention provides the pump of a kind of pressure gauge at handle, for solution need not the additional designs Decompression valves, the gas in the pump can be released by flexible pipe automatically, and the problem that pressure gauge is made zero is main goal of the invention.Another goal of the invention of the present invention is for the pump of a kind of pressure gauge at handle, and the user carries out need not to carry out extra disappointing action after the aeration, and pressure gauge meeting auto zero makes the operator that preferable convenience of use is arranged.
The present invention is a goal of the invention again, is for the pump of a kind of pressure gauge at handle, reaches aeration shows pressure in object to be inflatable and pressure gauge effect.
For achieving the above object, the present invention takes following technological means: a kind of pressure gauge is at the pump of handle, include: an aeration tube, comprise a base, a urceolus, a connecting rod and a tracheae, this base inside is provided with an air flue, this base connects establishes this urceolus, be provided with valve body in this urceolus, this valve body is provided with through hole, this through hole communicates in this air flue, and this connecting rod comprises first end and second end, and this connecting rod first end is inserted into this urceolus and is provided with a piston, this tracheae secure bond is in the valve body of this urceolus, and this tracheae is extended through piston and this connecting rod inside of this connecting rod; A handle, this handle are arranged in this connecting rod second end, and this handle is provided with a pressure gauge that can detect gas pressure value in the connecting rod; And a flexible pipe, comprising first end and second end, this flexible pipe first end is located at this base, and this flexible pipe second is terminated at object to be inflatable.
Beneficial effect of the present invention is, be provided with tracheae in the connecting rod of the present invention, and tracheae is incorporated into the valve body of urceolus, gas enters the air valve of base after via the aeration action, and the gas in the air valve enters flexible pipe and tracheae respectively, reaches aeration shows pressure in object to be inflatable and pressure gauge effect; The present invention need not the additional designs Decompression valves, and the gas in the pump can be released by flexible pipe automatically, and pressure gauge is made zero, and makes the operator that preferable convenience of use is arranged.
