[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] This utility model provides a filling and discharging sealing assembly, such as... Figures 1-6 As shown, the device includes a fixing ring 1, a connecting assembly 2 mounted on the upper part of the fixing ring 1, and a sealing cover 3 mounted on the outside of the connecting assembly 2. The connecting assembly 2 includes a main housing 21, the lower end of which is detachably connected to the fixing ring 1 via an inner connector 22, and the upper end of which is detachably connected to the sealing cover 3 via an outer connector 24. A movable assembly 25 is mounted in the middle of the main housing 21. The outer connector 24 is inserted into the air outlet of an external air pump. The outer wall of the inner connector 22 is provided with several vent holes 222. The movable assembly 25 includes a movable part 251. An external pressure plate 253 is installed on the top of the device. A vent is provided in the middle of the external pressure plate 253 to facilitate the introduction of gas into the device after an external air pump is connected. A sealing gasket 252 is installed at the bottom of the movable part 251. Normally, the sealing gasket 252 seals the external pressure plate 253. When inflating, the air pump outlet is inserted into the external connector 24 to push the movable part 251 downward, thereby causing the sealing gasket 252 to move downward and open the vent 222. A return spring 254 is sleeved on the outside of the movable part 251. The return spring 254 is used for the rebound and reset of the movable part 251.
[0025] In this embodiment, the fixing ring 1, the connecting component 2 and the sealing cover 3 are connected by an anti-detachment component 4 to prevent them from separating and falling off after each component is opened.
[0026] Specifically, the anti-detachment component 4 includes an upper ring 41, a middle ring 42, and a lower ring 43. The upper ring 41 is connected to the sealing cap 3, the middle ring 42 is connected to the connecting component 2, and the lower ring 43 is connected to the fixing ring 1. The upper ring 41 and the middle ring 42 are connected by an upper connecting strap 44, and the middle ring 42 and the lower ring 43 are connected by a lower connecting strap 45, which facilitates connection and fixation.
[0027] Furthermore, the middle of the fixing ring 1 is provided with a first internal thread 11, and the outer wall of the inner connector 22 is provided with a first external thread 221. The first internal thread 11 and the first external thread 221 are threadedly connected. The fixing ring 1 is installed on the air bag, and then the connecting component 2 is installed on the air bag.
[0028] Furthermore, the outer wall of the outer connector 24 is provided with a second external thread 242, and the outer connector 24 is connected to the inner thread of the sealing cover 3 through the second external thread 242, which facilitates the sealing cover 3 to be tightly sealed.
[0029] Furthermore, a sealing ring 23 is installed on the main housing 21 above the first external thread 221 to ensure the sealing of the connecting assembly 2 when it is installed on the fixing ring 1.
[0030] Furthermore, a positioning element 26 is installed in the middle of the main housing 21, and several sliders are provided on the outer wall of the movable element 251. An opening is provided in the middle of the positioning element 26, and a groove is provided on the inner wall of the opening. The movable element 251 passes through the positioning element 26, and the movable element 251 can move vertically through the cooperation of the slider and the groove. The sealing gasket 252 is located below the positioning element 26. Under normal circumstances, due to the high pressure inside the bag, the sealing gasket 252 is pressed tightly against the positioning element 26 to achieve a seal inside the main housing 21. When inflating, the sealing gasket 252 is pushed downward to open the vent 222, so that the air pump can smoothly inflate the air bag. When it is necessary to deflate, the connecting component 2 can be directly removed.
[0031] In use, the sealing assembly for inflation and deflation of this invention operates as follows: During inflation, the outlet of the external air pump is tightly connected to the external connector 24 via a plug-in joint, forming a stable connection. This pushes the movable part 251 downwards, causing the sealing gasket 252 to move downwards and open. When the air pump starts, high-pressure gas enters the main housing 21 through the external connector 24. The movable part 25 plays a crucial role in this process. Under the action of the air pump outlet, the movable part 251 is pushed downwards, simultaneously moving the sealing gasket 252 at its bottom downwards. This action opens the vent 222 on the internal connector 22, allowing gas to pass smoothly into the air bag. After inflation, the air pump outlet is pulled out, at which point the return spring 254 springs the movable part 251 back to its original position, ensuring airtightness.
[0032] During the venting process, the user can quickly vent simply by disassembling the connecting component 2. Since the fixing ring 1, the connecting component 2, and the sealing cover 3 are connected by the anti-detachment component 4, this design not only ensures the stability of the connection after opening, but also effectively prevents the components from separating and falling off.
[0033] In addition, the slider and groove design between the positioning member 26 and the moving member 251 ensures that the moving member 251 can move stably up and down inside the main housing 21, further enhancing the durability and reliability of the component.
[0034] In summary, the sealing assembly for filling and discharging of this utility model, through its unique design and the interaction between its components, enables fast, simple, and safe filling and discharging operations, greatly improving user experience and work efficiency.
