Abstract
The utility model relates to a double-layer zipper air leakage prevention flexible air pipe, which comprises a flexible pipe body, wherein the flexible pipe body is correspondingly connected with an outer zipper along two outer side edges of an opening in the length direction of the flexible pipe body, a pipe body on one outer side edge of the outer zipper is provided with a cover edge for covering the outer zipper, two inner side edges of the opening of the flexible pipe body are correspondingly connected with an inner zipper, the pulling and closing direction of the inner zipper is opposite to or the same as that of the outer zipper, and closing seams of the inner and outer zippers are staggered on the circumference of the flexible pipe body. The novel zipper sealing device is simple in structure, can effectively prevent the zipper from being loosened, and improves the sealing performance of the zipper closing seam.
Description
Technical Field
The utility model relates to an air duct structure, in particular to a double-layer zipper air leakage-proof flexible air duct.
Background
In the flexible air duct structure, the prior art patent adopts a mode that a sheet material is combined with a zipper to be assembled into a tubular structure on site, and the prior art adopts a mode that a cover edge structure is covered on the zipper for ensuring the sealing performance of the zipper. But rely on the zip fastener alone and cover the setting on limit, the zip fastener pull head is pulled full in tuber pipe length direction back, exists and receives the impact to lead to the zip fastener to take off hidden danger to the limit just relies on the magic to paste the taut cover of bonding, can't accomplish to the whole cover of zip fastener, when carrying high-pressure high-speed gas in inside, zip fastener seam and zip fastener pine takes off the department and still can be by the outside air leakage of limit, influence performance.
Disclosure of Invention
The utility model provides a double-layer zipper air leakage prevention flexible air pipe which has a simple structure, can effectively prevent the zipper from loosening and improve the sealing performance at the zipper joint.
The technical scheme adopted by the utility model is as follows: the utility model provides a flexible tuber pipe of double-deck zip fastener leak protection wind, includes flexible body, and flexible body corresponds the joint along flexible body length direction open-ended two outside limits and sets up outer zip fastener, sets up the lid limit that covers outer zip fastener on the body of the outer side of outer zip fastener, its characterized in that: the two inner side edges of the opening of the flexible pipe body are correspondingly connected with an inner zipper, the pulling and closing direction of the inner zipper is opposite to or the same as that of the outer zipper, and the closing seams of the inner zipper and the outer zipper are staggered on the circumference of the flexible pipe body.
The socket and the pulling piece of the outer zipper are outwards provided with a button-pressing male head, the front end and the rear end of the flexible pipe body in the length direction of the cover edge are inwards provided with a button-pressing female head, and the button-pressing male head is matched with the button-pressing female head.
The cover Bian Chao is internally provided with a magic tape hook surface, and the flexible pipe body corresponds to the magic tape burr surface.
The zipper cloth belt of the outer zipper side facing the inner zipper is downward and the zipper cloth belt of the inner zipper side facing the outer zipper is upward, and a magic tape is matched between the zipper cloth belt of the outer zipper side facing the inner zipper and the zipper cloth belt of the inner zipper side facing the outer zipper.
The beneficial effects of the utility model are as follows:
1. the inner zipper and the outer zipper are adopted, the pulling and closing directions of the two zippers are opposite and optimal, the single zipper Shan Cela can be prevented from being loosened due to the closing force, the closing seams of the inner zipper and the outer zipper are misplaced, the cloth belts at the misplaced middle positions are bonded by using the magic tape, when high-speed high-pressure gas is conveyed, the air is firstly sealed through the inner zipper, then is leak-proof through the bonding at the misplaced middle positions, and finally is covered by the outer zipper closing seam and the cover edge, and the three-channel air leakage prevention device is good in overall sealing performance.
2. The male button heads are arranged on the outer zipper socket and the pull piece, the female button heads at the two ends in the cover edge are matched to be buckled with each other, so that the cover strength of the cover edge can be improved, the stability of the outer zipper socket and the pull piece, which are subjected to internal gas weight and external impact after being pulled and closed, is further improved, the tail and the head of the outer zipper are effectively prevented from loosening, and the overall sealing and leakage-preventing performance of the air pipe is further improved.
Drawings
FIG. 1 is a schematic diagram of the structure of the present utility model;
fig. 2 is a schematic cross-sectional view of fig. 1.
In the figure: the flexible pipe body 1, the outer pull chain 2, the socket 3, the pull piece 4, the button buckle male head 5, the cloth belt 6, the cover edge 7, the magic tape 8, the button buckle female head 9 and the inner pull chain 10.
Detailed Description
Further description is provided below with reference to the accompanying drawings.
Fig. 1 and 2 show: a flexible air pipe with double-layer zippers for preventing air leakage is characterized in that an outer zipper 2 is correspondingly arranged on two outer side edges of an opening of a flexible pipe body in a length direction, a cover edge 7 for covering the outer zipper is arranged on the pipe body on one outer side edge of the outer zipper 2, an inner zipper 10 is correspondingly arranged on two inner side edges of the opening of the flexible pipe body 1 in a joint mode, the pulling-in direction of the inner zipper 10 is opposite to that of the outer zipper 2, closing seams of the inner and outer zippers are staggered on the circumference of the flexible pipe body, and a magic tape 8 is matched between a zipper cloth belt 6 on one side of the outer zipper, which faces downwards, of the inner zipper and a zipper cloth belt on one side of the inner zipper, which faces upwards; the socket 3 and the pull tab 4 of the outer zipper 2 are outwards provided with a button male head 5, the front end and the rear end of the cover edge 7 along the length direction of the flexible pipe body are inwards provided with a button female head 9, and the button male head is matched with the button female head.
In this embodiment, the cover edge 7 is adhered to the flexible pipe body 1 by using a velcro tape.
