[0002] An inflatable tent consists of a tent fabric and multiple inflatable columns that support the tent fabric.

[0003] In existing technologies, the assembly of tent fabric and inflatable columns is a wrapping assembly. That is, the tent fabric is typically wrapped around the inflatable columns using a cover, thus securing the columns and enabling the tent to be erected. However, the production, connection, and wrapping of the cover to the tent fabric require significant material and labor costs.

[0004] CN209976149U describes an inflatable tent, comprising a tent fabric, an inflatable keel for supporting the tent fabric, a first buckle on the tent fabric, and a second buckle on the inflatable keel, which can engage with the first buckle, making the assembly of the tent fabric and the inflatable keel very convenient, and also easy to disassemble.

[0005] This connection method has the following problems: First, the buckle connection is not reliable enough and is easy to come loose; second, the force is uneven and the fastener is easy to break; and third, the fastener is between the air tube and the fabric, which will wear down the waterproof coating on the fabric and cause the tent to leak.

[0037] A connection structure between an inflatable column 5 and the tent body, as described in Embodiment 1. Figures 1 to 7 As shown, the tent consists of a first tent body fabric 1, a second tent body fabric 2, a connecting strip 3, an inflation tube sleeve 4, and an inflation column 5. The inflation tube sleeve 4 is used to insert the inflation column 5. The first tent body fabric 1, the second tent body fabric 2, and the first side of the connecting strip 3 are sewn together. The first tent body fabric 1 and the second tent body fabric 2 form the tent fabric. The inflation tube sleeve 4 is sewn together with the second side of the connecting strip 3. This invention reduces the splicing process, thus lowering the manufacturing difficulty and saving material costs. In traditional connection methods, due to the numerous splicing points, complex waterproof structures are required at each splice, resulting in high material consumption and cumbersome processes. This invention, by optimizing the connection structure, reduces the number of splicing points, correspondingly reducing the need for waterproof structures, lowering the amount of waterproof tape and other materials used, and reducing costs.

[0038] Both the first tent body fabric 1 and the second tent body fabric 2 are made of high-density polyethylene. This gives the tent body excellent abrasion resistance and waterproofness, effectively extending the tent's lifespan while ensuring performance in outdoor environments.

[0039] Reflective strips can be installed on the surface of the tent fabric to reflect light at night or in low-light conditions, improving the tent's visibility in outdoor environments and increasing user safety.

[0040] like Figures 1 to 6 As shown, the inflatable tube sleeve 4 includes a first tube sleeve fabric 6 and a second tube sleeve fabric 7; the design of the inflatable tube sleeve 4 including the first tube sleeve fabric 6 and the second tube sleeve fabric 7 makes the manufacturing of the inflatable tube sleeve 4 more flexible and convenient to adjust and customize according to inflatable columns 5 of different sizes and shapes.

[0041] The first side of the first sleeve fabric 6 is sewn together with the first side of the second sleeve fabric 7; the second sides of the first sleeve fabric 6 and the second sleeve fabric 7 are both sewn together with the second side of the connecting strip 3. The connection method of the inflatable sleeve 4 and the sewing of the connecting strip 3 enhance the firmness of the connection between the inflatable sleeve 4 and the connecting strip 3, further improve the stability of the overall structure, and ensure that the inflatable sleeve 4 and the connecting strip 3 will not easily separate during use.

[0042] The air tube sleeve 4 is located inside the tent body, and the air column 5 is also located inside the tent body. This design makes the tent look neater and more aesthetically pleasing, while also preventing the air column 5 and air tube sleeve 4 from being directly frictioned and damaged by the external environment.

[0043] The inflation sleeve 4 is equipped with a zipper 15. Opening the zipper 15 allows for the installation or removal of the inflation column 5. The zipper 15 on the inflation sleeve 4 facilitates quick installation or removal of the inflation column 5, improving the ease of use of the tent.

[0044] A preferred embodiment of this invention is that both ends of the inflatable tube sleeve 4 are evenly provided with adhesive structures, such as zippers 15 or Velcro. This makes installation and removal more convenient, especially when the inflatable column 5 is long, allowing for easier installation and removal.

[0045] The inner wall of the inflation sleeve 4 is provided with anti-slip texture, which increases the friction between the inflation sleeve 4 and the inflation column 5, preventing the inflation column 5 from shifting or sliding within the inflation sleeve 4, and ensuring the stability of the connection between the inflation column 5 and the tent body. This avoids uneven tent support caused by displacement of the inflation column 5, which could affect the normal use and stability of the tent, thus improving the safety and reliability of the tent during use.

[0046] The inflatable column 5 is a hollow tubular structure made of an airtight material, such as TPU. TPU is a polymer material between rubber and plastic, possessing excellent elasticity. This high elasticity allows the inflatable column 5 to undergo significant deformation under external force and quickly return to its original shape after the force is removed. This ensures that the inflatable column 5 can inflate properly and provide stable support for the tent. Simultaneously, TPU material also has good abrasion resistance, low-temperature resistance, and UV resistance, enabling it to adapt to different outdoor environments and extending the service life of the inflatable column 5.

[0047] The width of the connecting strip 3 is optimally 4-6 cm. This suitable width ensures that the connecting strip 3 provides sufficient connection strength without adding unnecessary weight and material costs due to excessive width. In a further preferred embodiment, the connecting strip 3 is made of elastic fabric, whose elasticity coefficient ensures that the connecting strip 3 can stretch appropriately when the inflatable column 5 is inflated, thereby creating a uniform tensile force distribution on the tent fabric and preventing localized stress concentration that could damage the tent fabric.

[0048] A first waterproof strip 8 is provided at the connection between the first tent fabric piece 1 and the connecting strip 3; a second waterproof strip 9 is provided at the connection between the second tent fabric piece 2 and the connecting strip 3. This application provides further waterproofing treatment at the connection between the tent fabric and the connecting strip 3 by providing the first and second waterproof strips, effectively preventing rainwater from seeping through the connection and enhancing the waterproof performance of the tent.

[0049] Specifically, this application employs adhesive to bond both the first waterproof strip 8 and the second waterproof strip 9 to the tent fabric and the inflation tube sleeve 4. In the manufacture of an inflatable tent, for areas unsuitable for sewing, such as those requiring waterproofing, adhesive bonding can be used. This effectively prevents fabric damage, maintaining its integrity and aesthetics, while also providing good bonding strength. On one hand, the high bonding strength ensures long-term waterproofing; on the other hand, it avoids fabric damage that may occur due to sewing or other operations, maintaining the tent's overall integrity and aesthetics.

[0050] The first waterproof strip 8 has a first bend 11 along its length, dividing it into two first side strips 12, which are respectively attached to the connecting strip 3 and the first tent fabric 1. The second waterproof strip 9 has a second bend 13 along its length, dividing it into two second side strips 14, which are respectively attached to the connecting strip 3 and the second tent fabric 2. This structural design, dividing the first and second waterproof strips 8 and 9 into two side strips and attaching them to the connecting strip 3 and the tent fabric respectively, increases the contact area between the strips and the components, further improving the adhesion of the waterproof strips and making the waterproofing effect more reliable. It also enhances the overall integrity and structural strength of the joints.

[0051] This invention describes the connection structure between an inflatable column and a tent body. Specific examples are used to illustrate the principle and implementation of this invention. The descriptions of these embodiments are merely for the purpose of helping to understand this invention and its core concepts. It should be noted that those skilled in the art can make various improvements and modifications to this invention without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this invention.
