Description

Technical Field

[0001] The utility model belongs to the technical field of inflatable pools, and in particular relates to a bottom sheet connection structure of an inflatable pool. Background Art

[0002] The inflatable pool is a miniaturized version of the real swimming pool. It is light and easy to carry, so it can be used in many occasions, such as small parks, roadsides, homes, etc. Just fill the inflatable pool with gas and inject a certain amount of water into it before using it.

[0003] Nowadays, with the widespread application of inflatable pools, in order to ensure the overall strength of the inflatable pools, the connection structure between the components is also constantly improving. Among them, the comparative document 201821847822.3 discloses a drawstring and an inflatable pool for an inflatable pool, which are mainly used to solve the problem of reducing air leakage or water leakage in the inflation chamber of the inflatable pool, while taking into account the sensory quality of the product. However, the following problems have arisen during the long-term production and subsequent feedback from use: 1. The welding point between the pool bottom film and the pool side wall coincides with the welding point on the pool side wall itself, which can easily cause partial leakage during the second welding process. 2. There is no reserved space between the welding point and the reinforcement belt set therein. After the inflatable pool is filled with gas, it is easy to forcibly pull the reinforcement belt to produce wrinkles. After the wrinkles are squeezed against each other, it is also easy to cause leakage. In order to further optimize the pool bottom film connection structure solution, practitioners have designed an inflatable pool bottom film connection structure. Utility Model Content

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Embodiment 1:

[0025] Combination Figures 1 to 3 The inflatable pool bottom film connection structure shown in the figure includes a pool side wall 1 with a hollow interior. The hollow setting is convenient for inflation through the inflation port 5 to form support, and is convenient for storage after deflation. A pool bottom film 2 is arranged below the pool side wall 1, and a bottom covering material 3 is arranged between the pool side wall 1 and the pool bottom film 2. The bottom covering material 3 is welded to the pool side wall 1 and the pool bottom film 2 respectively, and the welding method adopts high-frequency welding. The welding point constitutes a first sealing point 301, and two groups of first sealing points 301 are arranged. The two groups of settings can ensure the overall sealing effect after the connection. A reserved part 302 is arranged between the two groups of first sealing points 301. The reserved part ensures that the connection has a certain ductility after the pool is inflated, which can reduce the wrinkling phenomenon in this part, ensure the aesthetics and improve the strength. End folding ears 303 are arranged at both ends of the bottom covering material 3, and the end folding ears 303 are used to cover the first sealing point 301 after folding, so as to ensure the overall appearance while further strengthening the sealing of the welding point.

[0026] In this embodiment, a reserved space is provided between the bottom of the pool side wall 1 and the pool bottom sheet 2 to ensure that a certain expansion space is provided to the pool side wall 1 after being inflated, thereby further reducing the pressure on the welding joint.

[0027] In this embodiment, the pool side wall 1 includes two groups of surrounding sheets 101 arranged opposite to each other, and a number of pulling wires 102 are evenly distributed between the two groups of surrounding sheets 101. The pulling wires 102 are used to strengthen the overall strength of the pool side wall 1 after inflation. The two groups of surrounding sheets 101 are provided with edge sealing sheets 103 at the upper and lower ends. The surrounding sheets 101 and the edge sealing sheets 103 are sealed by welding. The welding point constitutes a second sealing point 104, thereby forming a pool side wall 1 with strong sealing performance.

[0028] In this embodiment, the first sealing point 301 located on the side wall 1 of the pool is arranged above the second sealing point 104. This arrangement can preferentially stagger the first sealing point 301 and the second sealing point 104, thereby preventing the two welding points from overlapping and possible air leakage during the second welding.

[0029] In this embodiment, the end folded ear 303 is folded and connected to the first sealing point 301 by bonding. The bonding method can adapt to good sealing between different materials, and is easy to operate and highly adjustable when errors occur.

[0030] In this embodiment, the end folded ear 303 is integrally arranged with the bottom covering material 3 , and the integrally arranged end folded ear 303 belongs to the end reserved portion of the bottom covering material 3 , so that the connection strength between the end folded ear 303 and the bottom covering material 3 can be ensured.

[0031] In this embodiment, a handle 4 is provided on the outer wall above the side wall 1 of the pool, and the handle 4 is convenient for moving the position of the pool at a later time. An inflation port 5 is provided on the outer wall below the side wall 1 of the pool, and the inflation port 5 is connected with the cavity of the side wall 1 of the pool, so as to facilitate subsequent inflation. A water injection port 6 is provided on one side of the inflation port 5 and is connected with the cavity of the side wall 1 of the pool, so as to facilitate the subsequent water injection of the pool.

[0032] Embodiment 2: The connection method between the end folded ear and the bottom covering material in the embodiment 2 is improved on the basis of the above embodiment. The technical contents disclosed in the above embodiment are not described repeatedly, and the contents of the above disclosed embodiment also belong to the contents disclosed in the embodiment 2.

[0033] One embodiment of the utility model, combined with Figure 4 As shown, the end folded ear 303 and the bottom covering material 3 are separately arranged, and the end folded ear 303 and the bottom covering material 3 are connected by bonding. This arrangement has lower connection strength than that of the first embodiment, but the separate arrangement can facilitate replacement and adjustment when the bottom covering material 3 is incorrectly arranged.
