Inflatable group inflatable tight structure improvement

This creation is related to the technical field related to manual inflation, and in particular to the improvement of an inflatable group and an intimate structure.

Referring to Figure 12, the conventional inflator assembly includes a pumping mechanism 90 and a nozzle mechanism 80; wherein the nozzle mechanism 80 is normally attached to an inflator (not shown). The pumping mechanism 90 includes an air bag 91 and an air outlet head 92 that connects the air bag 91. The air nozzle mechanism 80 includes a cover 81 with a plug hole 811, a bottom cover 82 fixed to the bottom end of the cover 81, and a valve plug rod extending through the insertion hole 811 and the communication hole 821. 83. A valve plug ring 84 disposed outside the end of the valve plug rod 83, a set of elastic members 85 disposed on the outer periphery of the valve plug rod 83 and pushing the end of the valve plug rod 83 and the bottom cover 82, and a plurality of accommodating elements The spacer 86 is inserted into the hole 811.

By the composition of the above-mentioned members, the air outlet head 92 of the air pumping mechanism 90 is inserted into the insertion hole 821 of the cover mechanism 82 of the air nozzle mechanism 80 and is screwed, and the air outlet head 92 is pressed against the spacer 86 to maintain The outer peripheral side of the air outlet head 92 is airtight to the insertion hole 821.

It is conventional to use the air outlet head 92 to press against the spacer 86 to achieve a hermetic structural design, and there are many defects, such as:

1. The air outlet head 92 can be selectively inserted into the insertion hole 811 of the cover 81 and connected by means of a twist lock, so the structure must maintain a large tolerance, and the thickness of the spacer 86 Will affect the ease of the air head 92 twist lock. An excessively thick spacer 86 causes a reduction in tolerance, which is very laborious for the user to twist the lock, and is also likely to cause rapid wear of the gasket 86. Once worn, the airtight effect is reduced. On the other hand, when the thickness of the spacer 86 is insufficient, since the air outlet head 92 cannot form a tight fit with the spacer 86, the airtight effect is poor.

2. The gasket 86 is placed in the insertion hole 811, and is easily deformed due to repeated stress and twisting, and is also easily deformed by aging, so that when the air outlet head 92 is inserted, it is impossible to apply pressure to the gasket on average. On 86, the airtight effect is not good.

3. The inflator (not shown) is in a closed shape, and an internal pressure is formed after the gas is driven into the air pumping mechanism 90. There is a considerable chance that when the air is inflated, the internal pressure is fed back to the pumping mechanism 90 to generate a thrust due to the gas. The nozzle mechanism 80 is made of a plastic material and is easily deformed by force, so that the air outlet head 92 of the air pumping mechanism 90 is slightly displaced from the direction of the air nozzle mechanism 80 due to the deformation of the air nozzle mechanism 80, so that the air outlet head 92 is pressed against the spacer 86. The deadlock effect produces slack, and the air leak problem occurs in which the deadlock effect fails.

In view of the problems and deficiencies of the above-mentioned prior art, the main purpose of the present invention is to provide an improved inflation and tight structure of the inflatable group. By designing the structure, in addition to ensuring smooth operation of related components, airtightness can be ensured. maintain.

According to the above object of the present creation, an inflatable group is inflated and sealed. In a structural improvement, the inflatable group includes an air pumping mechanism and a gas nozzle mechanism; wherein the air nozzle mechanism is fixed to an inflator. The air pumping mechanism comprises an air bag, an air outlet head connected to the air bag, a set of a tight ring disposed on the outer periphery of the air outlet head, and a one-way air outlet valve housed in the air outlet head. The air nozzle mechanism includes a cover with a plug hole, and the hole of the plug hole has a tapered upper ring segment which is tapered from the top to the bottom, a bottom cover fixed at the bottom end of the cover, and a bottom cover having a communication hole. a valve plug rod extending through the insertion hole and the communication hole, a valve ring disposed on the outer side of one end of the valve plug rod, and a set on the outer circumference of the valve plug rod, and pushing the end of the valve plug rod and the bottom cover Elastic element. By the composition of the above-mentioned members, when the air outlet head is inserted into the insertion hole of the cover, the airtightness is formed by the abutment of the outer ring and the tapered upper ring segment.

Therefore, the above is a marble ball machine which can be quickly assembled and repaired by a preferred embodiment of the present invention, and various components and assembly methods are introduced. The actuation characteristics of the present embodiment are described below.

First, referring to FIGS. 6 to 10, when the inflator 300 is to be inflated, the air outlet head 12 of the air pumping mechanism 100 is aligned with the insertion hole 211 of the cover 21 of the nozzle mechanism 200, and the air outlet head 12 is The locking ribs 126 of the outer edge of the insertion portion 122 are respectively inserted and twisted corresponding to the locking groove 212 (known in the art). During the insertion of the insertion portion 122, the ejector shaft 125 (crossbar 1252) located in the socket 1221 of the insertion portion 122 presses against the stem 232 of the valve plug rod 23 to make the valve plug rod 23 self-closing position. (As shown in Fig. 7), the displacement to the gas injection position (as shown in Fig. 8) causes the tailstock seat 233 and the valve plug ring 24 to be separated from the end faces of the communication holes 221 (tapered lower ring segments 2211) of the bottom cover 22.

When the valve plug lever 23 is displaced to the air injection position (as shown in FIG. 8), the retaining ring 13 sleeved on the insertion portion 122 abuts against the tapered upper ring segment 2112 of the cover 21, so that the outer circumference of the air outlet head 12 is made. The side and the insertion hole 211 of the cover 21 are airtight. When the insertion portion 122 of the air outlet head 12 is deeper into the insertion hole 211 of the cover 21, the tapered upper ring segment 2112 is tapered by the tapered insertion hole 211, so that the air outlet head 12 and the cover 21 can be inserted into the hole. The 211 is closer.

At this time, the user can apply force to the airbag 11 (as shown in FIG. 9), so that the air in the air chamber 111 of the airbag 11 is forced to enter along the connecting hole 1211 of the air outlet head 12, the one-way air outlet valve 14, and the socket hole 1221. The cover 21 then enters the inflator 300 along the insertion hole 211 and the bottom cover 22 communication hole 221 . When the user releases the airbag 11 to return the shape (as shown in FIG. 10), the air in the inflator 300 is restricted by the one-way air outlet valve 14 and cannot be returned to the air chamber 111 of the airbag 11, so that the air chamber 111 of the airbag 11 It can only be inhaled from the air inlet 113.

This is repeated until the inflator 300 is filled with the required amount of air, and the pumping mechanism 100 can be rotated away from the nozzle mechanism 200. During the process, the valve plug rod 23 is no longer pushed by the ejector shaft 125 of the air outlet head 12, and is pushed against the force of the return of the elastic member 25, so that the valve plug rod 23 is self-injected (as shown in Fig. 8). The displacement to the closed position (as shown in Fig. 7) causes the tailstock seat 233 and the valve plug ring 24 to abut against the tapered lower ring segment 2211 of the communication hole 221 of the bottom cover 22.

Please refer to FIG. 11 for another embodiment of the present invention, wherein each member is the same as the above embodiment except that the airbag 11' can be a ball-type structure (such as FIG. 1). The illustrated) may also be a long strip having a foam therein with an air outlet providing a gas head connection. In the implementation, the inner air is output from the air outlet head 12 by pressure by holding the long airbag.

In addition, when the long air bag is stored, the ends can be folded in half to reduce the whole The volume of the body can be avoided, and the long strip-shaped airbag that avoids inflation takes up too much storage space.

The above description is only for the preferred embodiment of the present invention, and is intended to clarify the features of the present invention, and is not intended to limit the scope of the present embodiment, and the average variation made by those skilled in the art according to the present creation. Changes that are well known to those skilled in the art, and still fall within the scope of this creation.
