Description

Inline pressure gauge

This creation is about the technical field of an inflator, especially an in-line pressure gauge used with an inflator or as a tire pressure gauge.

Today, more and more people value leisure activities, and cycling is one of the common activities. During the cycling process, the tire pressure is an important factor affecting safety, so most people will prepare their own pumps to adjust the tire pressure at any time.

However, the general air pump does not provide a pressure display, so the user can only press the tire with the hand to determine whether the tire pressure is appropriate.

Another cylinder device is equipped with a pressure gauge design. The pressure gauge is exposed on the outer surface of the air pump. Although the air pumping device has a function of pressure display, the air pumping device is usually too bulky to be carried by the user.

The purpose of this creation is to solve the disadvantage that the pressure gauge of the conventional air pumping device is exposed and the overall volume is too large.

The purpose of this creation is to provide an in-line pressure gauge that provides good containment, reduces the chance of deflation, and improves the accuracy of the air pressure display.

The purpose of this creation is to provide an in-line pressure gauge that can be combined with different air pumping devices for a wider range of usability and convenience.

In order to achieve the above purposes and effects, the inline pressure gauge disclosed in the present invention comprises a barrel, a pressure display, a sealing block and a spring. The axial inner portion of the barrel has an accommodating space. The air pressure display is movably received in the accommodating space of the barrel. Further, the surface of the air pressure display has a scale; the air pressure display has a gas nozzle at one end and an engagement end at the other end; the axial interior of the air pressure display has a gas passage therethrough, and one end of the gas passage is located at the a gas nozzle, the other end of the gas passage is located at the engaging end; the sealing block is sleeved at the engaging end of the air pressure display and the peripheral surface contacts an inner wall surface of the receiving space of the barrel; the spring sleeve The outer periphery of the air pressure display is disposed at one end, and the other end abuts the one end of the receiving space of the barrel.

The following is a description of the preferred embodiment and the detailed description in conjunction with the drawings.

Referring to Figures 1 and 2, the pressure gauge disclosed in the figure comprises a barrel 10, a pressure display 20, a sealing block 30, and a spring 40.

The axial interior of the barrel 10 has an accommodation space 12. The air pressure display 20 is movably received in the accommodating space 12 of the barrel 10. Further, the surface of the air pressure display 20 has a scale 22; one end of the air pressure display 20 is a gas nozzle 24, and the other end is an engagement end 26; the axial interior of the air pressure display 20 has a gas passage 28 therethrough. One end of the gas passage 28 is located at the gas nozzle 24, and the other end of the gas passage 28 is located at the engagement end 26; a sealing block 30 is sleeved at the engagement end 26 of the air pressure display 20 and the peripheral surface contacts the An inner wall surface of the accommodating space 12 of the tubular body 10; a spring 40 is sleeved on the outer periphery of the air pressure display 20, one end abuts the engaging end 26, and the other end abuts against the accommodating space 12 of the barrel 10. One end.

Secondly, an outer end block 50 can be included for locking at one end of the barrel 10. The outer end block has a through hole 52 communicating with the accommodating space 12 of the barrel 10. A further set of mouth seals 60 (see Fig. 2) are disposed at the ends of the barrel 10 and are provided for passage of the nozzles 24. The sleeve seal 60 can be used to seal the spacing between the barrel 10 and the gas nozzle 24.

Referring to FIG. 3, the creation may further include an extension nozzle 70 disposed on the gas nozzle 24. And a connecting pipe 72 is connected to one end of the tubular body 10, and the outer end block 50 is coupled to the other end of the connecting pipe 72. The extension tube 70 is located at one end of the combination of the barrel 10, the air pressure display 20 and the spring 40. The connection tube 72 is located at the other end of the combination of the barrel 10, the air pressure display 20 and the spring 40. .

Referring to FIG. 4, the combination of the connecting tube 72 and the outer end block 50 can be connected to an inflator 80. The extension stub 70 can be coupled to an inflated member 82, such as a tire. The gas supplied from the pump 80 can be output to the member to be inflated 82 through the pressure gauge.

Referring to FIG. 5, the gas enters the inside of the barrel 10 and is output to the inside of the inflatable member (not shown) to form an isostatic state, and the pressure pushes the air pressure display 20, thereby causing the air pressure display 20 to protrude. The barrel 10 and the spring 40 are compressed. The user thus receives gas pressure from the scale 22 of the air pressure display 20. Since the sealing block 30 is in contact with the inner wall surface of the accommodating space 10 of the tubular body 10, it can provide good airtightness, reduce the probability of deflation, and improve the accuracy of the air pressure display 20.

Referring to FIG. 6, the combination of the pressure gauge disclosed in the present invention can be coupled to a holding pump 84. In particular, the barrel 10 is embedded in the axially inner portion of the hand-held pump 84. Further, one end of the barrel 10 is coupled to the extension tube 70, and the extension tube 70 is connected to the air nozzle 24 of the air pressure display 20. Thus, the gas supplied by the hand pump 80 is output by the gas passage 28 through the extension pipe 70.

Referring to FIG. 7, the present invention can be fitted with a joint 86 attached to the gas nozzle 24, and a closed end 88 formed at one end of the tubular body 10. So that the joint 86 is coupled to the inflated member (not shown), the gas in the inflated member can be input into the barrel 10 and push the sealing block 30 and the air pressure display 20, thereby making the scale 22 is exposed to show the gas pressure value of the member to be inflated.

The present invention is provided with a sealing block 30 which provides good airtightness, reduces the chance of deflation, and improves the accuracy of the air pressure display 20. In addition, this creation can be combined with different air pumping devices, so it has wider use and convenience.
