Description

Technical Field

[0001] The utility model belongs to the technical field of inflatable products, and in particular relates to a closed inflatable block with a reinforcement device. Background Art

[0002] In the existing Chinese patent database, a patent named "Stretching Reinforcement and Inflatable Product" is disclosed, with application number CN202320213603.4 and application date 2023-02-07. The device includes the following steps: weaving dense woven areas and pattern woven areas in sequence according to preset sizes, wherein the weaving density of the pattern woven area is lower than that of the dense woven area; locally applying glue along the surface of the dense woven area; after the gluing is completed, cutting is performed in the dense woven area according to needs to form a stretching reinforcement; wherein the pattern woven area between any two adjacent sections of the dense woven area is the height of the stretching reinforcement; by adopting a weaving method and using different weaving densities to form a woven dense woven area and a pattern woven area, the formed stretching reinforcement has the advantages of being strong, light and breathable, and local gluing can save costs and reduce weight, alleviating the technical problems of comprehensive gluing on the surface of the stretching reinforcement in the prior art, resulting in increased cost and weight of the inflatable product, and the stretching reinforcement blocking the airflow and affecting the inflation and deflation efficiency.

[0003] The inflatable products in the prior art lack a supporting structure inside, resulting in a small pressure on the internal cavity of the product. At the same time, it is easy to deform and cannot form the required inflatable structure. Therefore, this article aims to propose a closed inflatable block with a tie rod device. By arranging tie rods inside the inflatable product, the shape of the product after inflation can be better controlled while the internal cavity of the product can withstand greater pressure. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the inflatable products in the prior art lack a supporting structure inside, resulting in the internal cavity of the product to withstand a small pressure, and at the same time it is easy to deform and cannot form the required inflatable structure. In order to improve its shortcomings, the utility model provides a closed inflatable block with a tensioning device.

[0005] In order to achieve the above object, the utility model is realized by the following technical solutions:

[0006] A closed inflatable block with a tie rod device comprises a block body, wherein tie rods are arranged inside the block, one end of the tie rods are bent and heat-sealed to the upper surface of the block body, and the other end of the tie rods are bent and heat-sealed to the lower surface of the block body to form a vertical supporting structure, and an inflation valve and a pressure relief valve are arranged on the outer surface of the block body.

[0007] Compared with the prior art, the beneficial effects of the utility model are: due to the setting of the tie rods, the interior of the cavity of the product can withstand greater pressure after inflation; in addition, these tie rods can also better control the shape of the product after inflation, so that after the product is inflated, the middle position inside the cavity will not protrude too high and affect subsequent use. The device is suitable for industrial production and has strong practicality.

[0008] As a preferred embodiment, a plurality of first cloth tapes are heat-sealed to the edges of the front and back sides of the block, triangular rings are inserted into the first cloth tapes, a plurality of second cloth tapes are heat-sealed to the middle part of the block, waist-shaped holes are provided on the second cloth tapes, draw ropes are inserted into the triangular rings, and the draw ropes are arranged through the waist-shaped holes corresponding to the second cloth tapes.

[0009] As a preferred solution, the second cloth tape includes a long cloth tape and a short cloth tape.

[0010] As a preferred solution, the length direction of each of the long cloth strips is consistent with that of the corresponding short cloth strips.

[0011] As a preferred solution, the tie rod is a PVC plastic component. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a structural schematic diagram of the utility model.

[0013] Figure 2 It is a schematic diagram of the connection of the internal reinforcement of the block in the utility model.

[0014] In the figure: 1 block, 2 tension rods, 3 inflation valve, 4 pressure relief valve, 5 first cloth belt, 6 triangular ring, 7 second cloth belt, 8 waist-shaped hole. DETAILED DESCRIPTION

[0015] The technical solution of the present application is further described below in conjunction with the accompanying drawings and embodiments.

[0016] like Figure 1-2 As shown, a closed inflatable block with a tie rod device includes a block 1, a tie rod 2 is arranged in the block 1, one end of the tie rod 2 is bent and heat-sealed with the upper surface of the block 1, and the other end is bent and heat-sealed with the lower surface of the block 1 to form a vertical support structure, and an inflation valve 3 and a pressure relief valve 4 are arranged on the outer surface of the block 1. A plurality of first cloth tapes 5 are heat-sealed on the front and back edges of the block 1, and a triangular ring 6 is inserted in the first cloth tape 5. A plurality of strips of second cloth tapes 7 are heat-sealed in the middle part of the block 1, and a waist-shaped hole 8 is opened on the second cloth tape 7. A drawstring is inserted in the triangular ring 6, and the drawstring is arranged through the waist-shaped hole 8 corresponding to the second cloth tape 7. The second cloth tape 7 includes a long cloth tape and a short cloth tape. The length direction of each long cloth tape is consistent with that of the corresponding short cloth tape. The tie rod 2 is a PVC plastic component.

[0017] Before the block 1 is inflated, the tie rod 2 is preheated and closed on the inner surface of the block 1. After the block 1 is inflated by the inflation valve 3, the tie rod 2 becomes a supporting structure, so that the block 1 can better control its shape after inflation. At the same time, in order to facilitate the connection and use of multiple blocks 1, the pull rope is passed through the triangular ring 6, the long cloth belt and the short cloth belt in sequence, so that the block 1 can be used as a buoyancy block on the water surface.

[0018] The present utility model is not limited to the above-mentioned embodiments. On the basis of the technical solution disclosed in the present utility model, technicians in this field can make some substitutions and deformations to some technical features therein according to the disclosed technical content without creative labor, and these substitutions and deformations are all within the protection scope of the present utility model.
