DETAILED DESCRIPTION

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0020] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0021] The utility model embodiment provides an indoor transparent ball screen with a sealing structure, such as Figure 1-4 As shown, it includes a base 1, a card slot 2 is opened on the top of the base 1, and a PVC inflatable transparent ball curtain body 3 is arranged at the upper position of the base 1. The PVC inflatable transparent ball curtain body 3 is a hemispherical structure, and an inflatable sealing ring sleeve 4 is integrally formed at the bottom of the PVC inflatable transparent ball curtain body 3, and a door hole 5 is opened on the outer wall of one side of the PVC inflatable transparent ball curtain body 3 near the upper position of the inflatable sealing ring sleeve 4, a lower outer waterproof cover 6 is fixed to the outer position of the top of the base 1 near the card slot 2 by sealing waterproof adhesive, and a lower inner waterproof cover 7 is fixed to the inner position of the top of the base 1 near the card slot 2 by sealing waterproof adhesive, and the inflatable The bottom of the sealing ring sleeve 4 is fixed with an upper outer waterproof sleeve 8 and an upper inner waterproof sleeve 9 by sealing waterproof adhesive. The upper outer waterproof sleeve 8 is located on the outside of the upper inner waterproof sleeve 9. The PVC inflatable transparent ball curtain body 3 is a hemispherical structure. A waterproof zipper 10 is provided between the lower outer waterproof sleeve 6 and the upper outer waterproof sleeve 8 and between the lower inner waterproof sleeve 7 and the upper inner waterproof sleeve 9. An inflatable airbag 11 is integrally formed between the bottom of the inflatable sealing ring sleeve 4 near the upper outer waterproof sleeve 8 and the upper inner waterproof sleeve 9. The inflatable sealing ring sleeve 4 and the inflatable airbag 11 are both connected to the PVC inflatable transparent ball curtain body 3, and the outer side wall of the inflated airbag 11 matches and fits with the inner side wall of the card slot 2.

[0022] It should be noted that, since the existing transparent inflatable ball curtain is mostly placed directly on the grass or the ground after being inflated, there is a gap between the bottom of the transparent inflatable ball curtain and the grass or the ground, rainwater and mosquitoes can easily enter the interior of the transparent inflatable ball curtain through the gap, and the transparent inflatable ball curtain lacks an effective sealing structure. In this embodiment, the lower outer waterproof cover 6 and the upper outer waterproof cover 8 are connected together by a waterproof zipper 10, and the lower inner waterproof cover 7 and the upper inner waterproof cover 9 are connected together to achieve sealing at the connection between the base 1 and the PVC inflatable transparent ball curtain body 3. The inflatable airbag 11 can be limited by the card slot 2 after expansion to prevent the inflatable airbag 11 from falling off from the card slot 2, and the inflated airbag 11 can be tightly attached to the inner side wall of the card slot 2 after expansion, so as to achieve sealing at the connection between the base 1 and the PVC inflatable transparent ball curtain body 3. The double sealing can prevent external water and mosquitoes from entering the PVC inflatable transparent ball curtain body 3.

[0023] Specifically, in this embodiment, the scheme mainly includes a lower outer waterproof cover 6, a lower inner waterproof cover 7, an upper outer waterproof cover 8, an upper inner waterproof cover 9 and a waterproof zipper 10. When the transparent ball screen is installed, the base 1 is placed on the grass or the ground. At this time, the contracted inflatable airbag 11 is inserted into the card slot 2, and air is pressed into the PVC inflatable transparent ball screen body 3, the inflatable sealing ring sleeve 4 and the inflatable airbag 11. The PVC inflatable transparent ball screen body 3, the inflatable sealing ring sleeve 4 and the inflatable airbag 11 expand. After the inflatable airbag 11 expands, its outer side wall is attached to the inner side wall of the card slot 2. Due to the card slot 2, the inflatable airbag 11 can be limited by the card slot 2 after expansion to prevent the inflatable airbag 11 from falling off from the card slot 2. The inflated airbag 11 is tightly attached to the inner wall of the card slot 2 after expansion, so that the base 1 and the PVC inflatable transparent ball curtain body 3 are initially sealed. The lower outer waterproof cover 6 and the upper outer waterproof cover 8 are connected together by the waterproof zipper 10, and the lower inner waterproof cover 7 and the upper inner waterproof cover 9 are connected together to achieve the base 1 and the PVC inflatable transparent ball curtain body 3 are sealed again. The double sealing can prevent external water and mosquitoes from entering the PVC inflatable transparent ball curtain body 3.

[0024] In a further preferred embodiment of the present invention, Figure 3-4 As shown, the horizontal cross-sections of the card slot 2 and the inflatable airbag 11 are both annular structures, and the vertical cross-sections of the card slot 2 and the inflatable airbag 11 are both T-shaped structures.

[0025] In this embodiment, through the T-shaped structure of the card slot 2, the card slot 2 can be used to limit the inflatable airbag 11 after expansion to prevent the inflatable airbag 11 from falling off from the card slot 2. After expansion, the inflatable airbag 11 is tightly attached to the inner wall of the card slot 2, thereby achieving preliminary sealing of the base 1 and the PVC inflatable transparent ball curtain body 3.

[0026] In a further preferred embodiment of the present invention, Figure 2 As shown, the lower outer waterproof cover 6, the lower inner waterproof cover 7, the upper outer waterproof cover 8 and the upper inner waterproof cover 9 are all annular structures.

[0027] In this embodiment, the connection between the base 1 and the PVC inflatable transparent ball curtain body 3 can be fully sealed by the lower outer waterproof cover 6, the lower inner waterproof cover 7, the upper outer waterproof cover 8 and the upper inner waterproof cover 9 of the annular structure.
