Description

Technical Field

[0001] This utility model relates to the field of inflation equipment technology, and in particular to an inflation connector. Background Technology

[0002] During the use of inflatable equipment, the stability of the connection between the air tube and the air nozzle is one of the key factors affecting the performance of the equipment and the user experience. This is especially true for equipment that requires long-term inflation or is used in complex environments, such as air mattresses, air mattresses, and air tents. This is particularly evident in the air mattresses commonly used in hospitals. The use of air mattresses makes bedridden patients more comfortable, and the contact surface between the body and the wavy mattress is more breathable, greatly reducing the possibility of bedsores. However, existing air mattresses use an interface between the air pump and the air mattress that is connected by a simple plug-and-play method. Although the operation is simple, the air tube and air nozzle are prone to loosening or even falling off due to external force or vibration during repeated use, which can lead to air leakage. This loosening not only reduces inflation efficiency but may also make the equipment difficult to use normally, causing safety risks. Utility Model Content

Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Example

[0016] Please combine Figure 1-4 This embodiment of an inflatable connector includes a connecting tube 1; a mounting sleeve 2, on the surface of which an installation mechanism is fixedly connected, and the mounting sleeve 2 is fixedly connected to one end of the outer surface of the connecting tube 1; and an installation mechanism, of which two are provided, respectively fixedly connected to both sides of the outer surface of the mounting sleeve 2. The connecting tube 1 is clamped to the connecting tube 2 11 by the installation mechanism, and a positioning mechanism is fixedly connected to the surface of the connecting tube 2 11. During the connection process, the personnel use the cooperation of the installation mechanism and the positioning mechanism to achieve a stable connection between the connecting tube 1 and the connecting tube 2 11, effectively avoiding the problem of the air pump's air pipe and the air nozzle of the air mattress being loose or falling off.

[0017] The installation mechanism includes an adjusting slot plate 3, with a pressing plate 4 slidably connected inside the adjusting slot plate 3. A pressure rod 5 is fixedly connected to the surface of the pressing plate 4, and a return spring 6 is fixedly connected to one end of the pressure rod 5. A receiving tube 7 is fixedly connected to the surface of the return spring 6, a guide rod 8 is fixedly connected to the surface of the pressing plate 4, an extension rod 9 is fixedly connected to the surface of the guide rod 8, and a shaped locking block 10 is rotatably connected to the surface of the extension rod 9. When installing connecting tube 1 and connecting tube 2 11, the operator first connects the two and then pushes the pressing plate 4. After the pressing plate 4 is subjected to force, it drives the guide rod 8, the extension rod 9, and the shaped locking block 10 to move towards connecting tube 2 11. At the same time, the movement of the pressing plate 4 stretches the return spring 6 inside the receiving tube 7 through the pressure rod 5. At this time, the return spring 6 stores elastic potential energy, providing power for the subsequent locking action.

[0018] The positioning mechanism includes a limiting plate 12. The surface of the limiting plate 12 has a through groove 13, and the inner wall of the limiting plate 12 has a slot 14. When the irregularly shaped locking block 10 moves to the position of the limiting plate 12, the operator rotates the angle of the irregularly shaped locking block 10 so that it coincides with the through groove 13, and then continues to push the pressing plate 4 so that the irregularly shaped locking block 10 passes through the through groove 13. After the irregularly shaped locking block 10 passes through the through groove 13, the operator readjusts its angle so that it coincides with the slot 14, and then slowly releases the pushing force on the pressing plate 4. Under the reset action of the reset spring 6, the irregularly shaped locking block 10 is retracted and locked into the slot 14. At this time, the irregularly shaped locking block 10 no longer moves. The preload of the reset spring 6 ensures that the irregularly shaped locking block 10 is firmly locked in the slot 14, thereby realizing a stable connection between the connecting pipe 1 and the connecting pipe 2, effectively preventing loosening and falling off.

[0019] The adjusting groove plate 3 is fixedly connected to the outer surface of the mounting sleeve 2, and the irregularly shaped locking block 10 is adapted to the through groove 13 and the locking slot 14. A guide groove 15 is provided on the surface of the adjusting groove plate 3, and a guide slider 16 is slidably connected inside the guide groove 15. The guide groove 15 and the guide slider 16 provide guidance for the movement of the pressing plate 4, ensuring that the pressing plate 4 can smoothly and accurately drive the guide rod 8, the extension rod 9, and the irregularly shaped locking block 10 during movement, thus improving the stability and reliability of the connection process. The guide slider 16 is fixedly connected to the surface of the pressing plate 4, and the receiving tube 7 is fixedly connected to the inner wall of the guide groove 15.

[0020] Connecting pipe 1 and connecting pipe 2 are connected to each other, and the irregularly shaped card block 10 is snapped into the inside of the card slot 14.

[0021] The implementation principle of an inflatable connector in this application embodiment is as follows: During the installation process, the personnel first connect the connecting pipe 1 and the connecting pipe 2 11, and then push the pressing plate 4. After the pressing plate 4 is subjected to force, it will drive the guide rod 8, the extension rod 9 and the irregularly shaped block 10 to move in the direction of the connecting pipe 2 11. At the same time, the movement of the pressing plate 4 stretches the return spring 6 inside the storage tube 7 through the pressure rod 5. When the irregularly shaped locking block 10 moves to the position of the limiting plate 12, the operator needs to rotate the angle of the irregularly shaped locking block 10 so that it coincides with the through groove 13, and then continue to push the pressing plate 4 so that the irregularly shaped locking block 10 passes through the through groove 13. After the irregularly shaped locking block 10 passes through the through groove 13, the operator adjusts its angle again so that it coincides with the locking slot 14, and then slowly releases the pushing force on the pressing plate 4. Under the reset action of the reset spring 6, the irregularly shaped locking block 10 is retracted and locked into the locking slot 14. At this time, the irregularly shaped locking block 10 no longer moves. The preload of the reset spring 6 ensures that the irregularly shaped locking block 10 is firmly locked in the locking slot 14, thereby realizing a stable connection between the connecting pipe 1 and the connecting pipe 2 11, effectively preventing loosening and falling off.
