Description

Technical Field

[0001] This utility model belongs to the field of transportation technology and relates to an automatically detachable quick-connect fitting for inserting a tube. Background Technology

[0002] Airbags are frequently used for protection in emergency situations involving aviation, aerospace, and automotive equipment. Currently, airbags used in aviation, aerospace, and automotive applications in China typically use quick-connect fittings to quickly connect the inflation tubing to the airbag. However, separating the inflation tubing from the airbag requires manual rather than automatic separation. Utility Model Content

[0003] The purpose of this invention is to provide an automatically detachable quick-connect fitting for inserting a cannula, which enables rapid connection and separation of the inflation tubing from the airbag inflation tubing.

[0004] The technical solution adopted by this utility model is as follows: an automatically detachable quick-connect insertion tube includes an air channel formed by an air supply line, a fixed part of the quick-connect insertion tube, a movable part of the quick-connect insertion tube, an adapter, and a double-layer airbag, as well as an airbag lifting ring and an auxiliary separation rope. The fixed part and the movable part of the quick-connect insertion tube are arranged on the air supply line. The movable part of the quick-connect insertion tube is provided with a small hole. The double-layer airbag is provided with an airbag lifting ring. One end of the auxiliary separation rope is tied to the airbag lifting ring, and the other end passes through the small hole reserved in the movable part of the quick-connect insertion tube so that the auxiliary separation rope is tightened until the movable part of the quick-connect insertion tube and the fixed part of the quick-connect insertion tube are detachable and knotted.

[0005] In the above scheme, the air supply pipeline includes air supply pipeline one, air supply pipeline two, and Y-shaped diversion air supply pipeline. Air supply pipeline one is connected to the fixed part of the quick-connect fitting for insertion, air supply pipeline two is connected to the Y-shaped diversion air supply pipeline, one end of air supply pipeline two is connected to the Y-shaped diversion air supply pipeline, and the other end is connected to the double-layer airbag.

[0006] In the above scheme, the adapter includes adapter one and adapter two, characterized in that the quick insertion connector fixing part is connected to air supply line one through adapter one, and air supply line two is connected to double-layer airbag through adapter two.

[0007] In the above solution, the quick-connect connector for the separation cannula also includes a circular fixing strap, which is attached to the double-layer airbag, and the airbag sling is connected to the double-layer airbag through the circular fixing strap.

[0008] In the above scheme, both gas supply line one and gas supply line two are high-pressure hoses. The circular fixing strap is made of textile material. The auxiliary separation rope is made of flexible polyester textile material.

[0009] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows: It provides an automatically detachable quick-connect cannula. After the airbag is fully inflated, the auxiliary separation rope pulls the movable part of the quick-connect cannula, causing the movable part to automatically separate from the fixed part, thus achieving separation of the quick-connect cannula. This device, based on the ability to quickly insert and remove the inflation tubing from the airbag inflation tubing, also achieves rapid automatic separation of the inflation tubing from the airbag inflation tubing, solving the problem of requiring manual separation of the quick-connect cannula. It fulfills the need for rapid inflation and disengagement of the airbag, thereby ensuring the safety of the occupants or equipment. Attached Figure Description

Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0015] Figure 1 - Figure 3 As shown, an automatically detachable quick-connect cannula includes an air supply line 1, an air supply line 2, a fixed part of the quick-connect cannula 3, a movable part of the quick-connect cannula 4, a Y-shaped shunt air supply line 5, an adapter 6, an airbag sling 7, an auxiliary separation rope 8, a circular fixing strap 9, a double-layer airbag 10, and an adapter 11. Air supply lines 1 and 2 are composed of high-pressure hoses and adapters. The circular fixing strap 9 is made of high-strength textile. The auxiliary separation rope 8 uses a high-strength, flame-retardant flexible polyester textile material.

[0016] One end of adapter 6 is connected to air supply line 1, and the other end is connected to the quick-connect fitting 3. One end of the movable part 4 of the quick-connect fitting is connected to the quick-connect fitting 3, and the other end is connected to the Y-shaped diversion air supply line 5. The movable part 4 of the quick-connect fitting has a small hole for tying one end of the auxiliary separation rope 8. The other end of the auxiliary separation rope 8 is tied to one end of the airbag hanging ring 7. The other end of the airbag hanging ring 7 is connected to one end of the circular ring fixing strap 9. The other end of the circular ring fixing strap 9 is pasted on the double-layer airbag 10. The other end of the Y-shaped diversion air supply line 5 is connected to air supply line 2. The other end of air supply line 2 is installed on the double-layer airbag 10 through adapter 2 11.

[0017] Without the auxiliary separation rope 8 installed, connect all the structures as shown in the diagram, inflate the double-layer airbag 10 to the working pressure, then tie one end of the auxiliary separation rope 8 to the airbag lifting ring 7, and pass the other end through the small hole reserved in the movable part 4 of the quick-connect fitting. Tighten the auxiliary separation rope 8 until the movable part 4 of the quick-connect fitting is just detachable from the fixed part 3. Mark the position where the auxiliary separation rope 8 passes through the small hole in the movable part 4 of the quick-connect fitting, and mark the end where one end of the auxiliary separation rope 8 is knotted with the airbag lifting ring 7. Measure the auxiliary separation rope 8. The distance between the two marked positions on the auxiliary separation rope 8 is the knot distance between the two ends of the auxiliary separation rope 8 and the airbag ring 7 and the movable part 4 of the quick-connect cannula. When the double-layer airbag 10 is not inflated, the movable part 4 of the quick-connect cannula is connected to the fixed part 3 of the quick-connect cannula. The distance between the airbag ring 7 and the movable part 4 of the quick-connect cannula is relatively close. The length of the auxiliary separation rope 8 is less than the distance between the airbag ring 7 and the movable part 4 of the quick-connect cannula, so the movable part 4 of the quick-connect cannula cannot be separated from the fixed part 3 of the quick-connect cannula.

[0018] When the double-layer airbag 10 is inflated, gas enters through air supply line 1, air supply line 2, quick-connect fitting fixed part 3, quick-connect fitting movable part 4, Y-shaped diversion air supply line 5, and adapter 2 11. The double-layer airbag 10 is equipped with a mounting base, which is connected to adapter 2 11. Gas can directly enter the double-layer airbag 10 through adapter 2 11, causing the double-layer airbag 10 to inflate. The distance between the airbag lifting ring 7 and the quick-connect fitting movable part 4 increases, but is still less than the length of the auxiliary separation rope 8.

[0019] When the double-layer airbag 10 is about to be fully inflated, the distance between the airbag ring 7 and the movable part 4 of the quick-connect cannula increases further. The length of the auxiliary separation rope 8 is less than the distance between the movable part 4 of the quick-connect cannula and the airbag ring 7, and a pulling force is generated. The pulling force of the auxiliary separation rope 8 causes the movable part 4 of the quick-connect cannula to separate from the fixed part 3 of the quick-connect cannula, thus completing the separation of the quick-connect cannula.

[0020] The above technical solutions are merely preferred embodiments of this utility model and should not be construed as limiting the scope of this utility model. Therefore, any equivalent changes made in accordance with the scope of this utility model patent shall still fall within the protection scope of this utility model.
