The inflating device of the outer portion 22 of the member 20 is inserted into the space 253, and the inflating device is provided with an opening 254 through the unit 251 to the end of the inner surface 21 of the engaging member 20. The extending direction of the slit 254 is defined as the slit direction D1. The slit direction D1 is parallel to the longitudinal direction Y, and the slit 254 is in communication with the inflator insertion space 253; and the reset unit 252 and the inflator passage unit 251 of the charge and discharge unit 25 are integrally formed of plastic, and the reset unit 252 An elastic restoring force F is generated, the elastic restoring force F having an elastic restoring force direction D2 that is perpendicular to the slit direction D1 and parallel to the horizontal direction X, and causes the reset unit 252 The opposite sides of the slit 254 apply an elastic restoring force F to the slit 254.

And the slit 254 is exposed, and the counterpart 20, the inflator passing unit 251 and the reset unit 252 are all formed by plastic injection molding, and the elastic resetting capability of the reset unit 252 is greater than that of the inflator. The elastic resetting capability of the unit is achieved by a plastic material of different characteristics; and a connecting member 30 is an integral structure of plastic injection molding, and the connecting member 30 is composed of an upper portion 31, a lower portion 32 and a side portion. 33 is connected to the upper portion 31 and the lower portion 32.

以上為本發明可調整氣壓之塑料彈性體的結構關係，該各對合件20是由塑料射出一體成形所製成，且該充洩氣單元25也是由塑料射出一體成形於對合件20上，因此該各對合件20是可快速地大量製造的構件，而當該各對合件20製作完成並對合之後，再射出成型該連結件30封閉該各對合件20，則於射出成型的過程中產生的瓦斯氣將會被封存於該各對合件20之間的容置空間24內，使該各對合件20對合並封存氣體，如此該彈性體藉由該各對合件20之間的氣體就能提供緩衝彈性的功效。The above is the structural relationship of the plastic elastomer capable of adjusting the air pressure, and the respective engaging members 20 are integrally formed by plastic injection molding, and the charging and deflating unit 25 is also integrally formed on the counterpart 20 by plastic injection. Therefore, each of the mating members 20 is a member that can be mass-produced quickly, and after the mating members 20 are finished and joined, the joint member 30 is again injection molded to close the mating members 20, and then the injection molding is performed. The gas generated in the process will be sealed in the accommodating space 24 between the respective mating members 20, so that the pair of mating members 20 are combined to seal the gas, so that the elastic body is used by the mating parts. A gas between 20 can provide cushioning elasticity.
而當該彈性體使用於不同的場合或不同的使用者使用時，所需的緩衝彈性能耐需求也有可能產生改變，此時就能藉由該對合件20上的充洩氣單元25進行充洩氣的動作，如第5、6圖所示，使用者可將充氣裝置的充氣頭A由該對合件20外面的充氣裝置插置空間253***，並使該充氣頭A貫穿該充氣裝置通過單元251的切口254，則該充氣頭A就能位於該二對合件20的內面21之間進行充氣，此時，該充氣頭A撐開該充氣裝置通過單元251的切口254，則該充氣裝置通過單元251因受該充氣頭A撐抵施力，該充氣裝置通過單元251也就會對成形其上的復位單元252施予向外擴張的力量，而由於該復位單元252的彈性復位力F是由切口254的兩側對該切口254施加彈性力，因此在進行充氣過程時，該充氣頭A雖然撐開該切口254，但該復位單元252會迫使該切口254緊密貼合於該充氣頭A，使該充氣頭A與切口254之間不會產生空隙，防止氣體外漏；而當充氣完成，使用者要拔取出該充氣裝置的充氣頭A時，拉拔該充氣頭A，當該充氣頭A脫離該切口254時，該復位單元252的彈性復位力F持續對切口254施力，使該切口254也迅速閉合，如第5圖所示，當該充氣頭A完全脫離該切口254時，該復位單元252也就能使該切口254回到最初的閉合狀態，防止氣體由該切口254洩出，且有 內部氣體產生的內壓加強閉合力。When the elastic body is used in different occasions or different users, the required cushioning elastic resistance requirement may also be changed, and the filling and deflating unit 25 on the pairing member 20 can be deflated. The action, as shown in FIGS. 5 and 6, the user can insert the inflation head A of the inflator from the inflator insertion space 253 outside the mating member 20, and let the inflator A pass through the inflator passage unit. The slit 254 of the 251, the inflatable head A can be inflated between the inner faces 21 of the two mating pieces 20, and at this time, the inflating head A opens the slit 254 of the inflating device through the unit 251, and the inflating The device passing unit 251 is biased by the inflating head A, and the inflating device passing unit 251 applies an outwardly expanding force to the reset unit 252 formed thereon, and the elastic restoring force due to the reset unit 252 F is an elastic force applied to the slit 254 by the both sides of the slit 254, so that when the inflation process is performed, the inflation head A expands the slit 254, but the reset unit 252 forces the slit 254 to closely fit the inflation. Head A, the inflation head A and No gap is formed between the ports 254 to prevent leakage of gas; and when the inflation is completed, when the user pulls out the inflator A of the inflator, the inflating head A is pulled, and when the inflating head A is separated from the slit 254 The elastic restoring force F of the resetting unit 252 continues to apply a force to the slit 254, so that the slit 254 is also quickly closed. As shown in FIG. 5, when the inflating head A is completely separated from the slit 254, the resetting unit 252 is also The slit 254 can be returned to the original closed state to prevent gas from escaping from the slit 254, and The internal pressure generated by the internal gas enhances the closing force.
另外，當使用者欲進行洩氣的動作時，只要將該充洩氣單元25的切口254撐開，則氣體就會由該切口254洩出，達到洩氣的目的，而當使用者對該切口254不再施予撐開的力量時，該復位單元252的彈性復位力F就能使該切口254回復到閉合的初始狀態。In addition, when the user wants to perform the deflation action, as long as the slit 254 of the deflation unit 25 is distracted, the gas is vented from the slit 254 to achieve the purpose of deflation, and when the user does not scribe the 254. When the expanding force is applied again, the elastic restoring force F of the resetting unit 252 returns the slit 254 to the closed initial state.
而由於本發明之可調整氣壓之塑料彈性體是由塑料射出成形所製成，並使結構成為一體，使得本發明可調整氣壓之塑料彈性體沒有結構缺陷，而該對合件20與該充氣裝置通過單元251及該復位單元252之間也沒有開放式的間隙，因此能確保氣體封存的能力，提供最佳的結構特性，且該彈性體又因設置了該充洩氣單元25，藉由該充洩氣單元25提供使用者可改變該彈性體的氣壓，也就改變了該彈性體的緩衝彈性能耐，使該彈性體的適用性更高，增加該彈性體的附加價值。However, since the adjustable air pressure plastic elastomer of the present invention is formed by plastic injection molding and the structure is integrated, the plastic elastomer of the present invention can adjust the air pressure without structural defects, and the counterpart 20 and the inflation There is also no open gap between the device passing unit 251 and the reset unit 252, so that the ability of gas sealing can be ensured, and the optimal structural characteristics can be provided, and the elastic body is provided with the charging and deflating unit 25, by the The charging and deflating unit 25 provides a user with the ability to change the air pressure of the elastic body, thereby changing the cushioning elastic resistance of the elastic body, making the flexibility of the elastic body higher, and increasing the added value of the elastic body.
