Description

Technical Field

[0001] This utility model relates to the field of outdoor equipment technology, and in particular to a waterproof connection structure for a tent and a tent. Background Technology

[0002] In existing technologies, waterproof sealing of tent zipper areas primarily relies on a single-layer waterproof cover structure. However, this approach has significant limitations and shortcomings: the single-layer waterproof structure provides only one level of water resistance (just one layer), and its impermeability has an inherent upper limit (a low penetration threshold). In practical use, rainwater can easily create leakage channels through the micropores of the material, defects caused by aging, or assembly gaps. More importantly, after long-term repeated use, the sealing performance of the single-layer structure deteriorates significantly, leading to a substantial decrease in waterproof reliability and a significantly increased risk of leakage. These issues are key technical bottlenecks restricting the performance and service life of existing tent waterproof connection structures. Utility Model Content

[0003] In view of this, the present invention provides a waterproof connection structure and a tent, which has a good waterproof effect. It uses four layers of materials to build a layered waterproof barrier. Each layer independently blocks water and forms a physical maze between the layers. The right-side plug is embedded in the gap between the two layers on the left to form a physical barrier structure. Rainwater is blocked by the four layers of materials, which significantly improves the reliability of waterproofing.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A waterproof connection structure for a tent includes a left waterproof cover and a right waterproof cover covering the surface of a connecting zipper. The left waterproof cover has a left fitting portion and a left covering portion separated by creases, which are folded upwards to form a bottom-up layered structure. The right waterproof cover has a right covering portion and a right insertion portion separated by creases, which are folded downwards to form a top-down layered structure. The right insertion portion is embedded in the gap between the left fitting portion and the left covering portion, forming a four-layered, staggered, labyrinthine waterproof barrier. The left fitting portion contacts the zipper surface, and the four-layered, staggered waterproof barrier forces rainwater to penetrate the right covering portion, the left covering portion, the right insertion portion, and the left fitting portion in succession before it can seep in.

[0006] A four-layered, interlocking physical waterproof barrier is formed. Through a tiered water-blocking path design, rainwater is forced to penetrate sequentially: right cover (first layer of water blocking) → left cover (secondary layer of water blocking) → right interlocking section (tertiary layer of water blocking) → left bonding section (final layer of water blocking), achieving a significant leap in waterproof performance compared to a single-layer structure. Supplemented by creases and self-locking compression, the crease structure ensures precise folding of the left and right waterproof covers, while the right interlocking section embeds into the gap between the two left layers, forming a physical maze barrier. Rainwater must penetrate all four layers to seep in, greatly improving waterproof reliability. The synergistic effect of material rigidity and thickness allows the four-layered, interlocking waterproof barrier to achieve self-locking fixation through mutual compression on both flat and curved zippers, eliminating the need for additional fasteners. This reduces installation complexity and avoids sealing failure due to aging of auxiliary parts. In the curved connection areas of the tent, the four-layer self-locking compression structure further enhances the interlayer compression force based on the curved surface, improving waterproof reliability.

[0007] Preferably, the width of the left cover is greater than the width of the zipper teeth.

[0008] The wider coverage area compensates for installation errors, and the zipper can still be completely covered even if the cover is offset laterally, thus improving the product's fault tolerance.

[0009] Preferably, the width of the right-side cover is greater than the width of the zipper teeth, and a water-guiding edge is formed on one side of it.

[0010] The water-guiding edge can play a certain role in guiding water flow, further enhancing the waterproof capability. The extra-wide design covers the full width of the zipper teeth and extends into the non-working area, eliminating the risk of water seepage due to gaps caused by zipper deformation.

[0011] Preferably, the four layers of overlapping waterproof barrier are stacked in the following order from bottom to top: left side fitting part, right side insertion part, left side covering part, and right side covering part, and the length of the right side insertion part is less than the width of the left side covering part.

[0012] The layering and dimensional constraints produce key benefits. The strictly defined stacking sequence ensures that the right-side interlocking part is always completely covered by the left-side covering part, preventing capillary water seepage caused by exposed interlocking ends. The length of the right-side interlocking part is less than the width of the left-side covering part, ensuring that the end of the interlocking part is at a safe distance from the edge, so that it will not be exposed even if the material shrinks. This dimensional relationship creates a progressive waterproof gradient with four layers of staggered waterproof barriers. After rainwater penetrates the left-side bonding part, it will form a secondary sealing interface at the junction of the right-side interlocking part and the left-side covering part.

[0013] Preferably, friction texture is provided between the lower surface of the left cover portion and the upper surface of the right insertion portion.

[0014] Friction textures enhance dynamic sealing, increasing the friction coefficient at the contact surface between the two layers, resisting interlayer displacement caused by external vibration or wind, and maintaining joint stability. Micro-groove structures disrupt the continuity of the water film, increasing capillary seepage resistance and extending the rainwater penetration path. Specific texture directions guide the lateral diffusion of a small amount of intruding water, preventing vertical penetration, while providing deformation compensation space for thermal expansion and contraction.

[0015] Preferably, the left and right waterproof covers are composed of a base fabric layer and a surface waterproof coating. The micropores of each waterproof coating layer are staggered.

[0016] The composite structure optimizes material performance. The base fabric layer provides mechanical strength support, and its high tensile modulus ensures that the folded parts do not loosen during repeated deformation, maintaining crease accuracy. The surface coating forms a continuous, non-porous waterproof membrane that directly blocks water molecule penetration. The synergistic effect of the base fabric and coating balances rigidity and flexibility. The high-strength support of the base fabric layer ensures that the four staggered waterproof barriers maintain a stable overlapping relationship in wind and rain. The surface waterproof coating forms an independent waterproof membrane on the surface of each material layer, achieving a dual improvement in material lifespan and sealing performance. The four staggered waterproof barriers construct a directional water-blocking path, requiring rainwater to penetrate sequentially: right cover layer → left cover layer → right interlocking part → left bonding part. The micropore distribution of each waterproof coating layer is staggered, forming a cascaded waterproof barrier.

[0017] Preferably, a detachable fixing component may be selectively provided between the right cover and the left cover.

[0018] Selective configuration provides application flexibility. In strong winds or extreme weather, the fixed components enhance the connection strength between the covers and prevent interlayer separation. For daily use, the components can be omitted, simplifying the disassembly and assembly process and avoiding parts wear. This design is compatible with temporary reinforcement needs and long-term maintenance-free scenarios, expanding the product's applicable environment range.

[0019] Preferably, the detachable fixing component is a discretely distributed Velcro dot or strip magnetic element.

[0020] Discrete fastening components optimize the user experience. Velcro dots provide strong localized fastening without affecting material flexibility, facilitating localized replacement and maintenance. Magnetic components offer contactless adsorption for quick alignment and installation. The discrete distribution avoids large-area coverage of the material surface, preserving the integrity of the waterproof coating while allowing the material to expand and contract freely with temperature changes.

[0021] Preferably, the left waterproof cover is provided with a left connecting flange at its base, and the right waterproof cover is provided with a right connecting flange at its base.

[0022] The flange design achieves a permanent seal through bolts or stitching, eliminating the risk of water leakage at the connection.

[0023] A tent comprising multiple modular tent structures and a waterproof connection structure as described above, wherein the multiple modular tent structures are connected by the waterproof connection structure.

[0024] Ensures continuous waterproofing for tents, covering various application scenarios such as carports and camping tents.

[0025] The advantages of this utility model compared to the prior art are:

[0026] Four-layer waterproof breakthrough: The right-side connector is embedded in the left-side double-layer gap to form a labyrinthine sealing structure. Rainwater needs to continuously penetrate four independent material layers (right-side cover → left-side cover → right-side connector → left-side bonding). The four independent material layers construct a geometrically increasing water-blocking path, and the probability of penetration decreases geometrically. Attached Figure Description

Therefore, they should not be construed as limitations on this application.

[0035] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0036] The technical solutions in this application will now be described with reference to the accompanying drawings. Example 1

[0037] This embodiment provides a waterproof connection structure for a tent, including a left waterproof cover 2 and a right waterproof cover 3 covering the surface of the connecting zipper 1. The left waterproof cover 2 has a left fitting portion 21 and a left covering portion 22 separated by creases, which are folded upwards to form a bottom-up stacked structure. The right waterproof cover 3 has a right covering portion 31 and a right insertion portion 32 separated by creases, which are folded downwards to form a top-down stacked structure. The right insertion portion 32 is embedded in the gap between the left fitting portion 21 and the left covering portion 22, forming a four-layer staggered physical maze barrier. The path is: right covering portion 31 → left covering portion 22 → right insertion portion 32 → left fitting portion 21. This structure reduces the probability of single-point penetration to less than 1 / 16 of the traditional single-layer solution, and the crease separation ensures molding accuracy. The left fitting portion is in contact with the zipper surface, and the four-layer staggered waterproof barrier forces rainwater to continuously penetrate the right covering portion, the left covering portion, the right insertion portion, and the left fitting portion before it can penetrate.

[0038] Through a four-layered, staggered, labyrinthine waterproof barrier design, the right-side connector is embedded in the gap between the two layers on the left, forming a physical barrier structure. Rainwater is blocked by the four layers of material, resulting in a significant leap in waterproof reliability. Supplemented by crease separation and self-locking compression, the crease structure ensures that the left and right waterproof covers can be precisely folded, and the right-side connector is embedded in the gap between the two layers on the left, forming a physical labyrinthine barrier. Rainwater must penetrate all four layers to seep in, greatly improving waterproof reliability. The synergistic effect of material rigidity and thickness allows the four-layered, staggered waterproof barrier to achieve self-locking fixation through mutual compression on both flat and curved zippers, eliminating the need for additional fasteners. This reduces installation complexity and avoids sealing failure caused by aging of auxiliary parts. In the curved connection areas of the tent, the four-layered self-locking compression structure further enhances the interlayer compression force based on the curved shape, improving waterproof reliability.

[0039] In this embodiment, the width of the left cover 22 is greater than the width of the toothed chain of the zipper 1.

[0040] The wider coverage area compensates for installation errors, and the zipper can still be completely covered even if the cover is offset laterally, thus improving the product's fault tolerance.

[0041] In this embodiment, the width of the right cover 31 is greater than the width of the toothed chain of the zipper 1, and its two sides extend outward to form a water-guiding edge 311.

[0042] The water-guiding edge 311 can play a certain role in guiding water flow, further enhancing the waterproof capability. The extra-wide design covers the full width of the zipper 1 teeth and extends to the non-working area, eliminating the risk of water seepage due to gaps caused by deformation of the zipper 1.

[0043] In this embodiment, the four layers of overlapping waterproof barrier are stacked in the following order from bottom to top: left side fitting part 21, right side insertion part 32, left side covering part 22, and right side covering part 31, and the length of the right side insertion part 32 is less than the width of the left side covering part 22.

[0044] The layering and dimensional constraints produce key benefits. The strictly defined stacking sequence ensures that the right-side insertion part 32 is always completely wrapped by the left-side covering part 22, preventing capillary water seepage caused by exposed insertion ends. The length of the right-side insertion part 32 is less than the width of the left-side covering part 22, ensuring that the end of the insertion part is at a safe distance from the edge, so that it will not be exposed even if the material shrinks. This dimensional relationship creates a progressive waterproof gradient with four layers of staggered waterproof barriers. After rainwater penetrates the left-side bonding part 21, it will form a secondary sealing interface at the junction of the right-side insertion part 32 and the left-side covering part 22.

[0045] In this embodiment, friction texture is provided between the lower surface of the left cover portion 22 and the upper surface of the right insertion portion 32.

[0046] Friction textures enhance dynamic sealing, increasing the friction coefficient at the contact surface between the two layers, resisting interlayer displacement caused by external vibration or wind, and maintaining joint stability. Micro-groove structures disrupt the continuity of the water film, increasing capillary seepage resistance and extending the rainwater penetration path. Specific texture directions guide the lateral diffusion of a small amount of intruding water, preventing vertical penetration, while providing deformation compensation space for thermal expansion and contraction.

[0047] In this embodiment, the left waterproof cover 2 and the right waterproof cover 3 are composed of a base fabric layer 201 and a surface waterproof coating 202.

[0048] The composite structure achieves optimized material performance. The base fabric layer 201 provides mechanical strength support, ensuring structural stability and crease accuracy during repeated deformation of the folded parts. The surface waterproof coating 202 forms a continuous, non-porous waterproof membrane that directly blocks water molecule penetration. The synergistic effect of the base fabric layer 201 and the surface waterproof coating 202 balances rigidity and flexibility. The high-strength support of the base fabric layer 201 ensures that the four staggered waterproof barriers maintain a stable overlapping relationship in wind and rain. The surface waterproof coating 202 forms an independent waterproof membrane at each interface, achieving a dual improvement in material lifespan and sealing performance.

[0049] In this embodiment, a left connecting flange 23 is provided at the root of the left waterproof cover 2, and a right connecting flange 33 is provided at the root of the right waterproof cover 3.

[0050] The design of the left connecting flange 23 and the right connecting flange 33 achieves a permanent seal by stitching, eliminating the risk of water leakage at the connection and preventing strong winds from blowing the cover off. Example 2

[0051] In this embodiment, the left and right connecting flanges are not stitched together; instead, other conventional connection methods are used to secure them to the tent base. For example:

[0052] - Snap-fit ​​connection: The flange edge is equipped with a flexible snap tongue, which forms a mechanical interlock with the slot of the tent base;

[0053] - Adhesive bonding and fixing: Weather-resistant adhesive is used to achieve a full circumferential seal between the flange and the tent base;

[0054] - Hot melt welding: The flange material is fused together with the tent base through a hot pressing process.

[0055] These alternative connection methods can also achieve permanent sealing and fixation, eliminate the risk of water leakage at the joint, and adapt to the needs of tent base materials of different types. Example 3

[0056] In this embodiment, a detachable fastening component may be selectively provided between the right cover and the left cover. This component is composed of discretely distributed Velcro dots.

[0057] The specific implementation method is as follows:

[0058] - Regularly arranged hook-and-loop dots are placed on the upper surface of the left cover 22;

[0059] - Velcro-like dots are provided on the lower surface of the right-side covering part 31;

[0060] - The diameter and spacing of the dots are adapted to the size of the cover plate.

[0061] When enhanced connection strength is required (e.g., in strong winds), press the corresponding area to engage the dots for a localized, strong bond; for routine disassembly, simply peel off the hook and loop fastener. The discrete distribution of the Velcro dots prevents large-area coverage of the material surface, preserving the integrity of the waterproof coating while allowing for deformation due to thermal expansion and contraction. This design provides a flexible reinforcement solution for extreme conditions while maintaining the main structure of the four-layer waterproof barrier. Example 4

[0062] In this embodiment, the detachable fixing component adopts a strip-shaped magnetic element, and the specific implementation is as follows:

[0063] - A flexible magnetic strip is embedded inside the left cover portion 22;

[0064] - A magnetic metal strip is embedded at the corresponding position of the right-side cover 31;

[0065] - Magnetic strips and metal strips are spaced apart along the length of the cover plate.

[0066] During installation, magnetic attraction enables automatic alignment and quick, contactless closure; disassembly involves applying appropriate peeling force. The magnetic components do not penetrate the material layers, preserving the continuity of the surface waterproof coating. Especially in humid environments, the magnetic connection is unaffected by moisture, avoiding the failure issues of traditional Velcro when wet. This solution provides a maintenance-free auxiliary fixing option for four-layer waterproof structures.

[0067] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
