[0045] The server provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0046] Embodiment 1:

[0047] like Figures 1 to 3 As shown, an embodiment of the present application provides a self-sealing non-woven bag, including a bag body 1 and a pair of hand-carrying ropes 2, and also includes a plurality of quick-release devices 3 for detachably connecting the ends of each hand-carrying rope 2 to the bag body 1; a sealing device 4 is installed on the top of the bag body 1 to close the bag opening.

[0048] Furthermore, the sealing device 4 includes: a pair of positive magnets 41, respectively installed on a pair of quick-release devices 3 on the same side; a pair of negative magnets 42, respectively installed on a pair of quick-release devices 3 on the other side, and the pair of positive magnets 41 and the pair of negative magnets 42 can be adsorbed correspondingly.

[0049] Furthermore, the quick-release device 3 includes a mounting hole 31, which is arranged on the side wall of the bag body 1; an outer sleeve 32, which can be inserted into the mounting hole 31, and an inner ring plate 33 is fixedly provided at the inner end; an inner sleeve 34, which is inserted into the outer sleeve 32 after passing through the end of the corresponding hand strap 2, and an outer ring plate 35 is fixedly provided at the outer end.

[0050] Furthermore, the quick-release device 3 also includes a plurality of slots 36, which are circumferentially spaced apart at the inner ends of the inner circumferential walls of the outer sleeves 32; a plurality of floating connectors 5, which can be floatably mounted on the inner ends of the inner sleeves 34; wherein the positive pole magnet 41 / negative pole magnet 42 can be floatably mounted on the inner end of the inner sleeve 34 via a spring, and the outer circumferential wall can contact and limit the position of each floating connector 5.

[0051] Furthermore, the quick-release device 3 also includes a limiting groove 37 , which passes through the middle of the positive pole magnet 41 / negative pole magnet 42 from top to bottom; an insertion rod 38 , which is slidably installed in the limiting groove 37 , and both ends are fixedly connected to the inner sleeve 34 .

[0052] In this embodiment of the present application, due to the above structure, when the bag body 1 is lifted by the pair of hand-carrying ropes 2, the pair of positive magnets 41 and the pair of negative magnets 42 are attracted to each other, so that the bag opening of the bag body 1 is closed. When the bag opening needs to be opened, the pair of hand-carrying ropes 2 or the bag opening of the bag body 1 is pulled to both sides, so that the pair of positive magnets 41 and the pair of negative magnets 42 can be separated, so that the bag opening of the bag body 1 is opened;

[0053] When the hand strap 2 needs to be replaced, the corresponding positive magnet 41 / negative magnet 42 is pressed into the inner end of the inner sleeve 34 to disengage from the cooperation with each floating connector 5, so that each floating connector 5 can be disengaged from the corresponding slot 36, and the fixation between the inner sleeve 34 and the outer sleeve 32 is released, and the inner sleeve 34 is pulled out of the outer sleeve 32 so that the end of the hand strap 2 is removed, and the end of the new hand strap 2 is sleeved on the outer end of the outer sleeve 32 so that the inner sleeve 34 is inserted into the outer sleeve 32, and the positive magnet 41 / negative magnet 42 is released. The spring releases elastic potential energy to push the positive magnet 41 / negative magnet 42 to cooperate with each floating connector 5, so that each floating connector 5 is inserted into the corresponding slot 36, and the replacement of the hand strap 2 is completed. At this time, the inner ring plate 33 abuts against the inner wall of the bag body 1, and the outer ring plate 35 abuts against the hand strap 2;

[0054] When the positive magnet 41 / negative magnet 42 slides in the inner cavity of the inner sleeve 34 , the limiting groove 37 is displaced and cooperates with the insertion rod 38 to limit the movement stroke of the positive magnet 41 / negative magnet 42 and prevent it from falling out of the inner cavity of the inner sleeve 34 .

[0055] Embodiment 2:

[0056] like Figures 2 to 3 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the floating connector 5 includes a through hole 51, which is arranged on the outer peripheral wall of the inner sleeve 34 and connected to the inner cavity of the inner sleeve 34; a lifting rod 52, which can be floated and installed in the through hole 51, and the outer end can be inserted into the slot 36; an elastic member 6, which is used to apply a thrust to the lifting rod 52 away from the slot 36.

[0057] Furthermore, the floating connector 5 further includes a guiding slope 53 , which is arranged at the bottom end of the lifting rod 52 toward the outer ring plate 35 .

[0058] Furthermore, the elastic member 6 includes a floating annular groove 61, which is arranged at the inner end of the through hole 51; a floating plate 62, which is fixed to the lower outer peripheral wall of the lifting rod 52; and a spring 63, which is sleeved on the outer side of the lifting rod 52, and its two ends are respectively abutted against the floating plate 62 and the inner end of the floating annular groove 61.

[0059] In this embodiment of the present application, due to the adoption of the above-mentioned structure, when the outer peripheral wall of the positive pole magnet 41 / negative pole magnet 42 contacts the inner end of each lifting rod 52, the outer end of each lifting rod 52 is respectively inserted into the corresponding slot 36, and each spring 2 63 is compressed and shortened. When the positive pole magnet 41 / negative pole magnet 42 is pressed and compressed into the inner end of the inner cavity of the inner sleeve 34, each spring 2 63 exerts elastic potential energy and cooperates with the corresponding floating plate 62 to push the outer end of each lifting rod 52 out of the corresponding slot 36, and the inner end extends into the inner sleeve 34. in the inner cavity until the inner surface of each lifting rod 52 abuts against the outer wall of the corresponding positive magnet 41 / negative magnet 42. When the outer end of each lifting rod 52 needs to be inserted into the corresponding slot 36, the positive magnet 41 / negative magnet 42 is released, and the spring 1 releases elastic potential energy to push the positive magnet 41 / negative magnet 42 to slide toward the outer end of the inner cavity of the inner sleeve 34, and cooperates with the guiding inclined surface 53 at the lower end of each lifting rod 52 to push the outer end of each lifting rod 52 into the corresponding slot 36, and each spring 2 63 is compressed and shortened.
