Embodiment 1

[0025] see Figure 1-2 , an air column bag with a co-extruded film air-locking air-tight body, comprising an outer casing 1 and an interface device 2 provided on the outer casing 1, the interface device 2 includes a wall sleeve 21, the wall sleeve 21 is connected with the outer sleeve 1, and the wall sleeve 21 is connected inside There is a connecting sleeve 28 extending into the outer casing 1, a connecting shaft sleeve 23 is fixed inside the wall sleeve 21, a first sealing cone sleeve 24 is connected to the lower end of the connecting shaft sleeve 23, and the outer surface of the connecting sleeve 28 is in contact with the first sealing cone. The inner wall of the sleeve 24 and the inner wall of the wall sleeve 21 are slidably connected with the extrusion device 4. The extrusion device 4 includes a push ring 44. A sealing cone 24 is deformed to seal the connecting sleeve 28 .

[0026] In this embodiment: the air nozzle is inserted into the interior of the wall sleeve 21, th...

Embodiment 2

[0028] This embodiment is an improvement made on the basis of Embodiment 1. The push ring 44 is connected to the locking device 3 , and the inner wall of the wall sleeve 21 is sleeved with the first pressing pad 22 at the position close to the first sealing cone sleeve 24 . A pressing pad 22 is in contact with the outside of the first sealing cone 24 , and the push ring 44 is against the outside of the first pressing pad 22 , and the first pressing pad 22 is pressed against the first seal by the axial movement of the push ring 44 . The tapered sleeve 24 is deformed to seal the connecting sleeve 28;

[0029]A conveying sleeve 26 is sleeved on the inner wall of the wall sleeve 21 near the connecting sleeve 28, a second pressing pad 25 is disposed on the conveying sleeve 26, and a second sealing cone sleeve 27 is disposed on the connecting sleeve 28. The second sealing cone sleeve 27 and the The second pressing pads 25 are all snapped into the inside of the first sealing cone 24,...

Embodiment 3

[0034] This embodiment is an improvement made on the basis of Embodiment 2. The locking device 3 includes an air delivery channel 31. The air delivery channel 31 is snapped into the inner wall of the wall sleeve 21, and one end of the air delivery channel 31 extends to the outer sleeve. 1, the other end of the air delivery channel 31 penetrates the inner wall of the wall sleeve 21 and is connected with a first folded pipe 32, and the inner wall of the wall sleeve 21 is provided with a second limit air cushion 34 and a first limit air cushion 33. The positioning air cushion 34 and the first limiting air cushion 33 wrap one end of the first folding tube 32. When the first folding tube 32 is inflated and unfolded, the second limiting air cushion 34 and the first limiting air cushion 33 are used to limit the first position. A folded tube 32 squeezes the second pressing pad 25 at an angle after inflation and expansion.

[0035] In this embodiment: when the gas fills the outer casin...

Abstract

The invention relates to the technical field of air column bags, and discloses an air column bag with a co-extruded film air-locking air-tight body, comprising an outer casing and an interface device provided on the outer casing, the interface device comprising a wall sleeve, and the wall sleeve is connected to the outer casing , the wall sleeve is connected with a connecting sleeve extending into the outer casing, the wall sleeve is provided with a first sealing cone sleeve, the outer surface of the connecting sleeve abuts against the inner wall of the first sealing cone sleeve, the wall An extrusion device is slidably connected to the inner wall of the sleeve, and the extrusion device includes a push ring. The push ring slides on the inner wall of the extrusion device. Seal the connection sleeve. In the present invention, the second pressing pad is arranged to uniformly apply pressure to the outer surface of the second sealing cone sleeve to better seal the connection sleeve, so that the device can be sealed in multiple stages through the cooperation of the first pressing pad and the second pressing pad. And has impact resistance.

Description

technical field [0001] The invention relates to the technical field of air-column bags, in particular to an air-column bag with a co-extruded film closed air-locked air-tight body. Background technique [0002] With the rapid development of social economy, air column bag, also known as buffer air column bag, inflatable bag, bubble column bag, and columnar inflatable bag, is a new type of packaging material filled with natural air in the 21st century. protection to minimize product shipping losses. The air-packing bag has anti-stretching and equalizing properties, good surface printing, and forms an airtight inflatable column through continuous pressing. [0003] However, the existing air-column bag of the co-extruded film air-locking air-sealing body has poor automatic air-locking effect and no impact resistance effect, resulting in the leakage of the internal gas; therefore, it does not meet the existing needs, and we propose a A needle-type positioning detection system d...
