Structural improvement of high pressure inflatable pump

This creation relates to a high-pressure inflatable pump, especially a pump structure that can be quickly inflated by releasing high-pressure gas after being filled with a carbon dioxide gas cylinder or other high-pressure gas cylinder.

A conventional high-pressure inflator includes a body 10 and a connecting sleeve 11 as shown in FIG. 1 and FIG. 2, as disclosed in Patent No. M423745 of the Chinese Patent Publication No. M423745. a gas nozzle joint 12, a valve plug 13, a control member 14, a reset member 15, a cylinder adapter 16 and a gas cylinder container 17, the body 10 having orthogonally shaped and connected one of the first air passages 101 and The second air passage 102; the connecting sleeve 11 is a hollow tubular body, is located in the first air passage 101, and is screwed with one of the first air passages 101, and the inner and outer sides of the connecting sleeve 11 are respectively sleeved. An O-ring 18 is provided; the air nozzle joint 12 is a hollow tubular body, one end of which is screwed into the screw end 103, and the inner and outer sides of the air nozzle joint 12 are respectively sleeved with an O-ring 18; A neck portion 131 is recessed on the outer side of the plug 13 , and a pressing portion 132 and a gas nozzle sleeve portion 133 are respectively disposed at the two ends of the valve plug 13 . The valve plug 13 is inserted into the connecting sleeve 11 and the gas. In the nozzle joint 12, the neck portion 131 is located on the inner side of the connecting sleeve 11 O-ring 18 And the O-ring 18 inside the gas nozzle joint 12; the control element 14 is screwed to the pressing portion 132; the resetting member 15 is sleeved between the pressing portion 132 and the connecting sleeve 11; The bottle connecting member 16 is sleeved in the second air passage 102 of the body 10, and has a hollow airflow hole 161 at the center thereof. The cylinder container 17 is screwed to the end of the second air passage 102 of the body 10, and the inside is formed. A gas cylinder chamber 171.

When the high-pressure inflator is in a normal state, the connecting sleeve 11, the air nozzle joint 12 and the valve plug 13 are airtight by the plurality of O-rings 18 against the valve plug 13; When the gas in the gas cylinder is pressed, the steering element 14 is pressed to cause the steering element 14 to displace the valve plug 13, and when the valve plug 13 is displaced to the position corresponding to the O-ring 18 of the neck portion 131, as shown in FIG. The neck portion 131 allows the first air passage 101 and the second air passage 102 to communicate with the outside, and the gas in the cylinder can be vented by the first air passage 101 and the second air passage 102 through the air nozzle joint 12.

However, the valve plug 13 must be inserted into the connecting sleeve 11 and the air nozzle joint 12 when being assembled, and connected to the steering element 14, and must also be positioned at an appropriate position to ensure the airtight effect in the normal state, resulting in a conventional high voltage. The internal components of the inflator are numerous and complicated, and the assembly is difficult, which is not conducive to mass production. At the same time, when the gas discharge flow rate is to be changed, the control element 14 and the valve plug 13 are also matched with the gas nozzle joint 12 The relative relationship state, the interlocking structural relationship will lead to a decrease in the certainty of the operation, and the smoothness of the operation will be affected once the structural assembly is not confirmed.

In view of this, the creator conceived and further studied and finally created a structural improvement of a high-pressure inflatable pump.

The present invention provides a structural improvement of a high pressure inflation pump, the main purpose of which is to simplify the internal structure of the high pressure inflation pump, which makes the production and assembly more convenient.

In order to achieve the above objective, the present invention provides a structural improvement of a high-pressure inflatable pump, comprising: a body having a first air passage and a second air passage connected to each other, wherein the two ends of the first air passage are respectively a screw portion and a a first air passage is formed near the opening, and a first O-ring is disposed between the threaded portion and the second air passage; a nozzle joint is a hollow tubular structure, One end is screwed to the screwing portion of the body; a valve plug is received in the first air passage, a neck is recessed on the outer side of the proximal end, and a pressing portion is disposed at the other end of the valve plug, the pressing portion is Passing through the opening, the valve is inserted at one end of the pressing portion and sleeved with a resetting element, and the resetting element is located between the pressing portion and the structural ring; a cylinder connecting member is received on the body The second air passage has a gas flow through hole therein; and a gas cylinder container is a hollow container structure, and the gas cylinder container is assembled to the body.
