Description

Technical Field

[0001] This utility model relates to the field of inflatable mat technology, and in particular to a double-person outdoor inflatable mat. Background Technology

[0002] A double-person inflatable outdoor mat is a portable rest equipment designed specifically for outdoor activities, primarily used in camping, picnics, and travel, providing users with a comfortable temporary sleeping or resting platform. Its definition can be summarized as: an airtight mat made of high-strength waterproof materials (such as PVC, TPU, etc.), which, when inflated, forms a cushioning layer of a certain thickness and support, effectively isolating the effects of ground moisture, cold, and unevenness. Inflatable mats typically employ a compartmentalized air chamber design to improve stability and pressure resistance, and are equipped with inflation nozzles for rapid inflation and deflation. Modern double-person inflatable mats often integrate additional features such as anti-slip surfaces and insulation layers to meet diverse needs in outdoor environments.

[0003] Currently, the inflation nozzles of most double-person outdoor inflatable mats are fixed to the mat surface using glue. This design has significant drawbacks in practical use. Glue-bonded inflation nozzles are prone to delamination or breakage due to the mechanical stress of inflation and deflation, as well as the effects of outdoor environments (such as UV radiation and temperature differences), leading to airtightness failure. Once damaged, users often cannot replace them themselves, usually requiring professional repair or replacement of the entire inflatable mat, increasing usage costs and wasting resources. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to provide a double-person outdoor inflatable mat to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides a double-person outdoor inflatable mat, comprising a double-layered inflatable mat body and an inflation nozzle body. The inflatable mat body includes an outer layer, and an inner layer is glued to the inner wall of the outer layer. One end of the inflatable mat body has two protruding structures for headrest areas, which are connected to the inner layer. A first mounting ring and a second mounting ring are glued to the outer surface of the outer layer and the inner wall of the inner layer. An assembly tube is fixedly connected between the first mounting ring and the second mounting ring. The inflation nozzle body is threadedly connected to the assembly tube. A blocking ring is fixedly connected to the inner wall of the assembly tube, and the top surface of the blocking ring is in contact with the bottom surface of the inflation nozzle body. A threaded tube is threadedly connected to the inner wall of the assembly tube, and the bottom surface of the threaded tube is in contact with the top surface of the inflation nozzle body. A protective ring is fixedly connected to the inner wall of the threaded tube, and the air inlet pipe of the inflation nozzle body is located inside the protective ring.

[0007] Preferably, the outer layer is made of polyvinyl chloride and the inner layer is made of thermoplastic polyurethane elastomer.

[0008] Preferably, in any of the above embodiments, the outer surface of the assembly tube is fixedly connected with a plurality of circumferentially arrayed reinforcing ribs, and the top of each of the plurality of reinforcing ribs is fixedly connected to a second mounting ring.

[0009] Preferably, in any of the above embodiments, the top surface of the protective ring is rotatably connected to a rubber plug via a rubber band, and the rubber plug is inserted into the air inlet pipe of the inflator body.

[0010] Preferably, the inner wall of the assembly tube is provided with a first internal thread and a second internal thread, the first internal thread and the second internal thread have opposite thread directions, the air inlet body is threaded to the assembly tube through the first internal thread, and the threaded tube is threaded to the assembly tube through the second internal thread.

[0011] Preferably, in any of the above embodiments, a sealing groove is provided on the top surface of the blocking ring, and a sealing ring is fixedly connected to the bottom surface of the inflation nozzle body, wherein the sealing ring is slidably connected to the blocking ring through the sealing groove.

[0012] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0013] 1. This inflatable mat features an innovative detachable inflator body design. During operation, first rotate the threaded tube to disengage it from the assembly tube along the second internal thread, releasing the inflator body from its fixation. Then, rotate the inflator body to separate it from the assembly tube along the first internal thread. The fit between the sealing ring and the sealing groove ensures that the sealing structure is not damaged during disassembly. This design completely avoids the defects of traditional glue bonding, allowing for quick replacement of the inflator when damaged, without the need for professional tools or glue repairs. The dual protection structure of the retaining ring and protective ring prevents damage to the inlet pipe of the inflator body during disassembly. The reverse thread design of the threaded tube ensures a secure fixation and easy operation, significantly improving the maintenance convenience and service life of the inflator.

[0014] 2. This inflatable mat adopts a double-layer composite structure with an outer and inner layer. The outer layer uses polyvinyl chloride (PVC) for abrasion and tear resistance, while the inner layer uses thermoplastic polyurethane elastomer to ensure airtightness and comfort. The first and second mounting rings are glued to the outer and inner layers respectively, forming a stable connection. The assembly tube, secured to the mounting rings with reinforcing ribs, provides reliable support for the inflation nozzle. This double-layer structure ensures the overall strength of the inflatable mat while fully utilizing the performance advantages of both materials. The raised structure and the connection design with the inner layer further enhance the comfort of the headrest area, making the inflatable mat more durable and comfortable for outdoor use.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited thereto.

[0023] like Figures 1 to 6 As shown, a double-person outdoor inflatable mat includes a double-layered inflatable mat body 1 and an inflation nozzle body 2. The inflatable mat body 1 includes an outer layer 101, and an inner layer 102 is glued to the inner wall of the outer layer 101. One end of the inflatable mat body 1 has two protruding structures 3 for the headrest area, which are connected to the inner layer 102. A first mounting ring 4 and a second mounting ring 5 are glued to the outer surface of the outer layer 101 and the inner wall of the inner layer 102. An assembly tube 6 is fixedly connected between the first mounting ring 4 and the second mounting ring 5. The inflation nozzle body 2 is threadedly connected to the assembly tube 6. A blocking ring 7 is fixedly connected to the inner wall of the assembly tube 6. The top surface of the blocking ring 7 is in contact with the bottom surface of the inflation nozzle body 2. A threaded tube 8 is threadedly connected to the inner wall of the assembly tube 6. The bottom surface of the threaded tube 8 is in contact with the top surface of the inflation nozzle body 2. A protective ring 9 is fixedly connected to the inner wall of the threaded tube 8. The air inlet pipe of the inflation nozzle body 2 is located inside the protective ring 9.

[0024] As an optional technical solution of this utility model, the outer layer 101 is made of polyvinyl chloride, and the inner layer 102 is made of thermoplastic polyurethane elastomer. The outer layer 101 is made of polyvinyl chloride, which has excellent wear resistance and tear resistance, and can effectively resist the wear and tear of the air pad in the complex outdoor environment. The inner layer 102 is made of thermoplastic polyurethane elastomer, which has good flexibility and air tightness, ensuring that the air pad is not prone to air leakage during long-term use, while providing a comfortable tactile experience, making outdoor rest more comfortable and durable.

[0025] As an optional technical solution of this utility model, the outer surface of the assembly tube 6 is fixedly connected with a plurality of circumferentially arrayed reinforcing ribs 10, and the top of each of the plurality of reinforcing ribs 10 is fixedly connected to the second mounting ring 5. The circumferentially arrayed reinforcing ribs 10 on the outer surface of the assembly tube 6 and the fixed connection with the second mounting ring 5 can significantly improve the overall strength and stability of the inflation nozzle structure, prevent deformation or loosening of the connection parts due to frequent inflation and deflation or external force, and ensure that the inflatable pad can maintain reliable airtightness and structural integrity even after long-term use.

[0026] As an optional technical solution of this utility model, the top surface of the protective ring 9 is rotatably connected to a rubber plug 11 via a rubber belt. The rubber plug 11 is inserted into the air inlet pipe of the air nozzle body 2. The protective ring 9 is rotatably connected to the rubber plug 11 via a rubber belt, so that the plug can be flexibly opened and closed and tightly inserted into the air inlet pipe of the air nozzle body 2, effectively preventing foreign objects such as dust and water vapor from entering the air nozzle, avoiding blockage or corrosion of the air valve. At the same time, the rubber material ensures sealing and extends the service life of the air cushion.

[0027] As an optional technical solution of this utility model, the inner wall of the assembly tube 6 is provided with a first internal thread 12 and a second internal thread 13. The first internal thread 12 and the second internal thread 13 have opposite thread directions. The inflation nozzle body 2 is threadedly connected to the assembly tube 6 through the first internal thread 12, and the threaded tube 8 is threadedly connected to the assembly tube 6 through the second internal thread 13. The inner wall of the assembly tube 6 is provided with the first internal thread 12 and the second internal thread 13, and the two have opposite thread directions, so that the inflation nozzle body 2 and the threaded tube 8 can be firmly locked by the reverse threads, preventing the connection from loosening due to vibration or external force, ensuring that the inflation nozzle can still maintain a stable seal in complex outdoor environments, and avoiding air leakage problems.

[0028] As an optional technical solution of this utility model, the top surface of the blocking ring 7 is provided with a sealing groove 14, and the bottom surface of the inflation nozzle body 2 is fixedly connected with a sealing ring 15. The sealing ring 15 is slidably connected to the blocking ring 7 through the sealing groove 14. The sealing groove 14 on the top surface of the blocking ring 7 slides and cooperates with the sealing ring 15 on the bottom surface of the inflation nozzle body 2 to form a double sealing structure, which further improves the air tightness of the inflation nozzle and prevents gas from leaking from the connection. At the same time, the sliding connection method facilitates disassembly and maintenance, ensuring that the inflation pad can maintain high-efficiency sealing performance even after long-term use.

[0029] A double-person outdoor inflatable mat works on the following principle:

[0030] 1): During operation, first rotate the threaded tube 8 to make it exit the assembly tube 6 along the second internal thread 13, thus releasing the fixation on the air nozzle body 2. Then rotate the air nozzle body 2 to separate it from the assembly tube 6 along the first internal thread 12.

[0031] 2) The fit between the sealing ring 15 and the sealing groove 14 ensures that the sealing structure will not be damaged during disassembly. This design completely avoids the defects of traditional glue bonding, and the inflation nozzle can be quickly replaced when damaged, without the need for professional tools or glue repair.

[0032] 3): The double protection structure of the blocking ring 7 and the protective ring 9 prevents damage to the air inlet pipe of the air nozzle body 2 during disassembly. The reverse thread design of the threaded pipe 8 ensures a firm fixation and easy operation.

[0033] In summary, this double-person outdoor inflatable mat features an innovative detachable inflation nozzle body 2. During operation, first rotate the threaded tube 8 to disengage it from the assembly tube 6 along the second internal thread 13, releasing the inflation nozzle body 2 from its fixation. Then, rotate the inflation nozzle body 2 to separate it from the assembly tube 6 along the first internal thread 12. The fit between the sealing ring 15 and the sealing groove 14 ensures that the sealing structure is not damaged during disassembly. This design completely avoids the defects of traditional glue bonding, allowing for quick replacement of the inflation nozzle when damaged, without the need for professional tools or glue repairs. The dual protection structure of the blocking ring 7 and the protective ring 9 prevents damage to the air inlet pipe of the inflation nozzle body 2 during disassembly. The reverse thread design of the threaded tube 8 ensures a secure fixation and easy operation, significantly improving the maintenance convenience and service life of the inflation nozzle. It employs a double-layer composite structure of an outer layer 101 and an inner layer 102. The outer layer 101 uses polyvinyl chloride for wear-resistant and tear-resistant protection, while the inner layer 102 uses thermoplastic polyurethane elastomer to ensure airtightness and comfort. The first mounting ring 4 and the second mounting ring 5 are fixed to the outer layer 101 and the inner layer 102 respectively with adhesive, forming a stable connection base. The assembly tube 6, fixed to the mounting rings by the reinforcing ribs 10, provides reliable installation support for the inflation nozzle body 2. This double-layer structure ensures the overall strength of the inflatable mat while fully utilizing the performance advantages of the two materials. The connection design between the raised structure 3 and the inner layer 102 further enhances the comfort of the headrest area, making the inflatable mat more durable and comfortable for outdoor use.
