Description

Inflator with rotating pressure gauge

The present invention relates to a pump, especially a pump with a rotating pressure gauge.

At present, there are many types of pumps on the market, which generally include a pumping body, a pressure gauge, and an air pipe. The pumping body has a base, a cylinder seat extending upward from the base, and a piston rod that can move up and down into the cylinder seat. The base defines an air outlet channel communicating with the cylinder base. The piston rod moves compressed air downwards, which generates high-pressure gas and sends it into the air outlet channel. The pressure gauge communicates with the gas outlet channel and can display the pressure of the high-pressure gas. The air guide pipe communicates with the air outlet channel and is used to guide the high-pressure gas to output outward.

However, because the pressure gauge is screwed on the base, it can be screwed to adjust the angle during use. However, this screw design not only has the problem of difficult positioning, but also easily loosens under long-term use. Therefore, the design of the pump still needs to be improved.

Therefore, the purpose of the present invention is to provide a pump with a rotary pressure gauge that can overcome at least the shortcomings of the prior art.

Therefore, the pump of the present invention with a rotating pressure gauge includes an pumping unit, a watch body unit, and an air guiding unit. The pumping unit defines an air outlet channel extending along a first axis, and an insertion channel extending along a second axis spaced transversely from the first axis. The insertion channel partially communicates with the air outlet channel. The watch body unit includes a pressure gauge, and a convex shaft extending outward from the pressure gauge and inserted into the air outlet channel, the convex shaft has a ring groove formed on the outer peripheral surface and corresponding to the insertion channel. The air guide unit includes a manifold that extends into the insertion channel and is embedded in the ring groove.

The effect of the present invention lies in: inserting the protruding shaft through the manifold, not only can be surely positioned, but also can not be loosened.

Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same number.

Referring to FIGS. 1, 2, and 3, one of the first embodiments of the present invention of a pump with a rotary pressure gauge includes an pump unit 1, a meter unit 2, and an air guide unit 3.

As far as the internal space is concerned, the air pumping unit 1 defines an actuating space 11 in which air can be compressed to generate high-pressure gas, an air outlet passage 12 extending along a first axis 121 and communicating with the actuating space 11, and a The insertion channel 13 extends along a second axis 131 spaced transversely from the first axis 121. The insertion channel 13 partially communicates with the air outlet channel 12.

In terms of the basic structure, the pumping unit 1 of the first embodiment is in the form of a foot pump. The pumping unit 1 includes a base 14, a cylinder base 15 extending upward from the base 14, and a A piston rod 16 that can move up and down into the cylinder base 15 and cooperate with the cylinder base 15 to define the actuating space 11, and a pedal that is provided at the top of the piston rod 16 and can be used to step down and press the piston rod 16 A plate 17, an elastic member 18 disposed between the cylinder base 15 and the piston rod 16 and having an elastic force to drive the piston rod 16 to return upward after being depressed, and a rotatably mounted on one side of the base 14 Auxiliary parts 19.

The base 14 has a boss portion 141 on the side of the barrel base 15 opposite to the auxiliary member 19 and protruding outward, the boss portion 141 is formed with a first inclined surface 142 facing away from the barrel base 15, and A channel surface 143 surrounding the gas outlet channel 12 is defined. The first inclined surface 142 gradually extends downward from a side near the cylinder base 15 to a side away from the cylinder base 15, perpendicular to the first axis 121 and At an angle of 45 degrees with the cylinder base 15, the air outlet channel 12 is inclined into the first inclined surface 142 along the first axis 121. The pedal 17 has a groove 171 formed on the top surface. The elastic member 18 is a compression spring. The auxiliary member 19 is U-shaped, and has two side rod sections 191 spaced apart on both sides of the pedal board 17 and one end pivotally connected to the base 14, and one end connecting the side rod sections 191 away from the base 14 And corresponding to the link segment 192 of the card groove 171.

The watch body unit 2 includes a pressure gauge 21, and a protruding shaft 22 protruding outward from the pressure gauge 21 and inserted into the air outlet passage 12 airtightly. The pressure gauge 21 has a surface 211 and a second inclined surface 212 abutting on the first inclined surface 142 of the boss portion 141, the second inclined surface 212 is perpendicular to the first axis 121 and is in contact with the boss portion 141 The slope of the first slope 142 is the same as that of the surface 211 at an angle of 45 degrees. As for the internal structure of the pressure gauge 21 and the operating principle for measuring the high-pressure gas, it is not the focus of this new model. This is no longer explained. The protrusion shaft 22 obliquely protrudes the pressure gauge 21 along the first axis 121 and is perpendicular to the second inclined surface 212, and is rotatably pivoted in the air outlet channel 12, the protrusion shaft 22 has a along the The first axis 121 extends from one end away from the pressure gauge 21 to the shaft hole 221 communicating with the pressure gauge 21, a through hole 222 transverse to the shaft hole 221 and communicating with the outer peripheral surface, and a depression formed on the outer peripheral surface A round and communicating the through hole 222 and the ring groove 223 of the insertion channel 13.

The gas guiding unit 3 is used to guide the high-pressure gas to be output outward, and includes a manifold 31 that extends into the insertion channel 13 and is inserted into the ring groove 223, and one end connected to the manifold 31 and extending outward Hose 32, an inflation head 33 mounted on one end of the hose 32 away from the manifold 31 and for ejecting the high-pressure gas, and an end cap 34 detachably sleeved on the other end of the manifold 31, And an airtight member 35 sleeved between the end of the manifold 31 away from the hose 32 and the end cover 34. The manifold 31 has a through hole 311 that communicates with the hose 32 from an end remote from the hose 32, and a through hole 312 that communicates laterally with the outer periphery of the through hole 311 and corresponds to the ring groove 223.

It is worth mentioning that the cross section of the ring groove 223 of the protruding shaft 22 is arc-shaped, and the cross section of the insertion channel 13 communicating with the ring groove 223 is circular, corresponding to the insertion of the ring groove 223 and the insert The manifold 31 of the insertion channel 13 has a circular tube shape. Therefore, when assembling, as long as the protruding shaft 22 is inserted into the air outlet channel 12, the manifold 31 is inserted from one end of the insertion channel 13, and the end cover 34 is inserted from the other end of the insertion channel 13 Screwing on the manifold 31, the manifold 31 can be positioned in the insertion channel 13 without being detached, and at the same time, by designing the partial outer peripheral surface of the manifold 31 to be fitted into the ring groove 223, The card limits the protruding shaft 22 so that the protruding shaft 22 cannot be detachably positioned in the air outlet channel 12 and can rotate around the first axis 121.

The following further describes the pumping situation of the pump, first swinging the auxiliary member 19 away from the cylinder base 15 and laying down on a floor, then stepping on the auxiliary member 19 with one foot for positioning, and the other foot on the pump When the pedal 17 is stepped on, the piston rod 16 is pressed down as shown in FIG. 4 to compress the air in the actuation space 11 into a high-pressure gas, and the high-pressure gas flows into the outlet passage 12 , And flows into the pressure gauge 21 from the projecting shaft 22, and also flows into the hose 32 from the manifold 31 and then is discharged from the inflation head 33. Then, when the pedal 17 is stepped on without force, as shown in FIG. 2, the piston rod 16 can be driven up by the reset elastic force of the elastic member 18 to be reset to the original state, which can be used to step on the intake air again.

It should be noted that, during use, the angle of the pressure gauge 21 can be changed as needed. As long as the pressure gauge 21 is rotated during adjustment, the protrusion shaft 22 is rotated 180 degrees in place in the air outlet channel 12, and the second The inclined surface 212 will relatively rotate on the first inclined surface 142, so that the watch body unit 2 switches between a use position (see FIG. 2) and a retracted position (see FIG. 5) relative to the pumping unit 1, such as As shown in FIG. 2, when the watch body unit 2 is in the use position, the surface 211 extends laterally and is horizontally placed upwards. When the pumping unit 1 is pumping, it can watch the pressure while pumping, and when the watch body When the unit 2 is in the stowed position, the surface 211 extends vertically and is placed upright to facilitate folding. As shown in FIG. 5, when the watch body unit 2 is located at the retracted position, the auxiliary member 19 can also be leaned against the barrel base 15 and swing upward, and the link segment 192 can be used to latch the latch groove 171 correspondingly. Therefore, the pedal 17 is limited to prevent it from moving and pumping up. Finally, the hose 32 can also be positioned around the periphery of the barrel base 15 in order to reduce the volume.

Referring to FIGS. 6 and 7, a second embodiment of a pump with a rotary pressure gauge of the present invention, the structure of the second embodiment is roughly the same as that of the first embodiment, the difference is that the shape of the pumping unit 1 is different, In the second embodiment, the pumping unit 1 is in the form of a hand-pressing pump. The pumping unit 1 also includes the base 14, the cylinder base 15, and the piston rod 16, except that the pumping unit 1 further includes a The handle 17' on the top of the piston rod 16 replaces the pedal 17 of FIG. 1 to allow the user to hold and inflate. At the same time, the inflator unit 1 also omits the setting of the elastic member 18 in FIG. The member 19 is modified to fix a pedal formed on at least one side of the base 14, so that the base 14 can be stably supported on a ground, and can be used by the user to step on and position during use.

In summary, the design of the pump with a rotary pressure gauge, through the design of the manifold 31 engaging the convex shaft 22, has the effect of reliable positioning, is not easy to loosen, and can improve product yield and use Life, so it can really achieve the purpose of new cost.

In addition, according to the design of the pump with a rotating pressure gauge, the design of the first inclined surface 142 of the base 14 and the second inclined surface 212 of the pressure gauge 21 allows the pressure gauge 21 to rotate to change the surface 211 Angle, the surface 211 is horizontal in the use position for easy viewing, so the size of the surface 211 can be relatively increased in order to read the pressure value, the surface 211 is upright in the collapsed position, does not protrude the base 14 , So you can reduce the storage space and reduce packaging volume.

However, the above are only examples of the new model. When the scope of the new model cannot be limited by this, any simple equivalent changes and modifications made according to the patent application scope and patent specification content of the new model are still regarded as Within the scope of this new patent.
