Description

Technical Field

[0001] This utility model relates to a trachea structure, specifically to a rotatable, tool-free, L-shaped multifunctional trachea device. Background Technology

[0002] In existing technologies, most inflatable hoses on the market adopt a straight hose structure, with the nozzle and hose designed coaxially. This structure requires the hose to be bent at a large angle to adapt to different inflation directions, which not only makes storage inconvenient but also easily causes wear and tear on the hose during repeated bending, leading to air leakage. To avoid this, some solutions use L-shaped hoses, but this structure usually requires tools for installation and removal, resulting in a poor user experience and low efficiency when quick replacement of nozzles or hoses is needed.

[0003] In addition, valve compatibility is a common problem in existing technologies. Most adapters on the market are of a single specification, supporting only one type of valve, either American or French, lacking universality. In cycling or outdoor scenarios, if users encounter different valve sizes, they must carry multiple adapters or hose assemblies, which is not only cumbersome but also increases the burden of carrying them, failing to meet diverse inflation needs.

[0004] In terms of structural sealing and flexibility, traditional L-shaped air hoses typically employ a rigid, fixed sealing structure. While this maintains a certain level of airtightness, it prevents adjustment of the hose angle during use. This lack of flexibility restricts operational freedom, leading to a poor user experience, especially in situations with limited space or inconvenient operating angles. Furthermore, while existing threaded valves offer stable connections, tightening and loosening the threads during cycling is time-consuming and complex, hindering rapid inflation. While push-button valves can save time, they often lack compatibility and cannot balance stability and efficiency.

[0005] Therefore, existing inflatable hoses mainly have the following problems: First, straight hoses are difficult to store and easily worn, while L-shaped hoses require tools to disassemble, making the operation cumbersome; Second, valve adapters generally have poor compatibility and cannot simultaneously support French and American valves; Third, there is a contradiction between the sealing structure and rotational flexibility, making it impossible to balance airtightness and angle adjustment; Fourth, threaded valves and push-button valves each have their own limitations in use and cannot meet users' dual needs for stability and convenience. Summary of the Invention

[0006] To address the aforementioned problems, this invention provides a rotatable, tool-free, L-shaped multifunctional tracheal device, which effectively overcomes the shortcomings of existing technologies.

[0007] This utility model is achieved through the following technical solution: a rotatable, tool-free, L-shaped multifunctional tracheal device, comprising: The air hose connector has a sealed air-conducting area in the middle, one end of the air hose connector is a screw-on position, and the other end of the air hose connector is a cylinder connector, which is connected to the inflation cylinder. A connecting tube, one end of which is a connecting bushing, the air tube connector is inserted into the connecting bushing through the sealed air guiding area, and the other end of the connecting tube is an adapter connector; The adapter is an integrated dual-purpose structure used to connect with different models of air nozzles, and the adapter connector is sealed to one end of the adapter.

[0008] As a preferred technical solution, one end of the adapter has a first 8V1 internal thread interface and a built-in 6V1 internal thread interface for connecting with a Presta French valve, and the other end has a second 8V1 internal thread interface with an American valve for connecting with a Schrader American valve.

[0009] As a preferred technical solution, the adapter connector is configured with an 8V1 external thread, which engages with the first 8V1 internal thread interface at one end of the adapter.

[0010] As a preferred technical solution, the sealed air guiding area includes an annular groove provided on the air pipe connector, a sealing ring is provided on each side of the annular groove, and a small air outlet is provided on the bottom surface of the annular groove. An air passage is provided between the connecting bushing and the connecting pipe. When the sealed air guiding area of ​​the air pipe connector is located inside the connecting bushing, the small air outlet is connected to the air passage.

[0011] As a preferred technical solution, the screwing position and the air pipe connector are integrally formed by a rubber-coating injection molding process.

[0012] As a preferred technical solution, the outside of the screwing position is provided with an anti-slip texture.

[0013] As a preferred technical solution, the connecting tube is a flexible air tube made of a highly elastic and flexible material.

[0014] The beneficial effects of this utility model are as follows: The tracheal connector of this utility model has a sealed air-guiding area in the middle, and an annular groove is formed on its outer periphery. Sealing rings are provided on both sides of the annular groove, and a small air outlet is provided at the bottom. When the tracheal connector is inserted into the connecting sleeve, the air outlet connects with the air passage of the connecting pipe, thus ensuring airtightness while allowing the tracheal connector to rotate 360° within the connecting pipe. Users can freely adjust the direction of the tracheal tube according to different usage angles, significantly improving operational flexibility and adaptability. Compared to the existing rigid L-shaped structure, this utility model can simultaneously achieve efficient sealing and multi-angle adjustment, greatly improving the user experience. This invention features a screw-in position at one end of the air hose connector, integrally molded using a rubber-coated injection molding process. The screw-in position also has an anti-slip texture, allowing users to quickly install or remove the air hose by hand without tools. The operation is simple and quick. Compared to traditional L-shaped air hoses that require wrenches or other tools for installation and removal, this invention significantly improves operational efficiency, enabling users to quickly replace air hoses while cycling or in outdoor settings, meeting emergency inflation needs. This utility model's adapter adopts an integrated dual-use structure. One end has an 8V1 thread and a built-in 6V1 thread, making it compatible with Presta French valves. The other end is a second 8V1 internal thread interface with an American valve, allowing direct connection to Schrader American valves, thus achieving universal compatibility with two mainstream valve types. This design avoids the inconvenience of users having to carry multiple adapters in different inflation scenarios, significantly improving the device's versatility and applicability.

[0017] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0018] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0019] like Figures 1-3 As shown in a specific embodiment of this utility model, a rotatable, tool-free, multi-functional air tube device is provided. The device consists of three main parts: an air tube connector 2, a connecting tube 6, and an adapter 9. Through reasonable structural cooperation and sealing design, the various parts achieve the functions of tool-free quick disassembly, adjustable angle, and compatibility with multiple air nozzles.

[0020] In this embodiment, the air hose connector 2 plays a crucial role in connection and air conduction. Its central area is designed as a sealed air conduction zone, with an annular groove 12 on its outer wall. Sealing rings 11 are installed on both sides of the annular groove 12, and a small air outlet hole 13 is formed on the bottom surface of the annular groove 12. When the air hose connector 2 is inserted into the connecting sleeve 4 at one end of the connecting pipe 6, the air outlet hole 13 communicates with the air passage 5 inside the connecting pipe 6, thus forming a stable gas transmission channel during inflation. The sealing ring 11 not only provides reliable airtightness but also allows the air hose connector 2 to rotate freely relative to the connecting pipe 6 in the inserted state, enabling the user to adjust the air hose direction according to actual needs. Through this design, the air hose maintains efficient sealing while achieving 360-degree rotation adjustment, ensuring operational flexibility and avoiding the inconvenience caused by the fixed angle of traditional L-shaped air hoses.

[0021] A screw-in position 1 is provided at one end of the air tube connector 2. This screw-in position 1 and the air tube connector 2 are integrally molded using a rubber-coated injection molding process, thus ensuring structural strength and sealing performance. The outer surface of the screw-in position 1 is further designed with anti-slip textures, allowing users to easily grip the screw-in position 1 with their hands during operation and easily install or remove the air tube without the need for additional tools such as wrenches. This structure enables quick replacement of the device during cycling or in outdoor scenarios, significantly improving usage efficiency. The integrated design of the screw-in position 1 and the air tube connector 2 also effectively avoids loosening or air leakage problems that may occur due to the splicing of multiple parts, improving overall reliability.

[0022] The other end of the air pipe connector 2 is equipped with a cylinder connector 3, which can be directly connected to the inflation cylinder to ensure stable gas input under high pressure. The cylinder connector 3 and the air pipe connector 2 are fitted with high-precision machined threads, thereby enhancing the stability and durability of the connection and maintaining good sealing even under repeated assembly and disassembly.

[0023] In this embodiment, one end of the connecting tube 6 is a connecting bushing 4, the internal dimensions of which match the sealing and air guiding area of ​​the air tube connector 2, allowing the air tube connector 2 to be smoothly installed and kept stable. The other end of the connecting tube 6 is provided with an adapter connector 7, which adopts an 8V1 external thread structure and can engage with the thread at one end of the adapter 9 to achieve a reliable sealing connection.

[0024] The connecting tube 6 features a flexible hose design and is made of a highly elastic flexible material. This material can withstand significant bending stress and maintain good resilience during repeated use, thus significantly improving the durability and safety of the air tube. The flexible connecting tube 6 allows the device to adapt to multi-angle operation during inflation, avoiding the risk of breakage or leakage caused by rigid tubing.

[0025] The adapter 9, as a key functional component of the device, is designed as an integrated dual-purpose structure. One end has a first 8V1 internal thread interface 8, and an internal 6V1 internal thread interface for connecting to the Presta French valve. When the user needs to inflate a tire equipped with a French valve, simply screw one end of the adapter 9 into the French valve to achieve a stable connection.

[0026] The other end of adapter 9 is a second 8V1 internal thread interface 10 with an American-style valve, used for connecting to a Schrader American-style valve. Users can directly connect this end to the American-style valve to achieve a sealed fit. Through this bidirectional design, adapter 9 can be compatible with both French and American standard valve interfaces in a single integrated structure, greatly improving the versatility and convenience of the device.

[0027] In actual use, the user first inserts the screw-in part 1 of the airway connector 2 into the connecting sleeve 4 of the connecting tube 6, and then tightens it to complete the positioning. Due to the anti-slip texture design on the outer surface of the screw-in part 1, the user can complete the operation by hand without the need for tools.

[0028] When the air pipe connector 2 enters the connecting bushing 4, the small air outlet 13 on its sealed air guiding area is connected to the air passage 5 inside the connecting pipe 6, forming a sealed and rotatable gas transmission path under the action of the sealing ring 11.

[0029] The user then selects the appropriate connection end of adapter 9 based on the desired inflatable object. For a Presta French valve, the connection is made via the first end of adapter 9; for a Schrader American valve, the connection is made directly via the other end of adapter 9. The entire process requires no additional tubing replacements or the carrying of multiple adapters 9, making it simple and efficient to use.

[0030] After inflation, the user can quickly disassemble the air hose connector 2 by twisting the screw 1. The flexible connecting tube 6 can be folded and stored, significantly reducing its size and making it convenient to carry. Compared with the traditional straight air hose that requires a large angle bend and the L-shaped air hose that requires tools for disassembly, this utility model can achieve the combined functions of space saving, tool-free quick disassembly, and compatibility with multiple air nozzles.

[0031] The specific implementation of this utility model achieves a balance between air tightness and rotational freedom through the matching design between the sealing air guiding area of ​​the air tube connector 2 and the connecting tube 6; it achieves tool-free quick assembly and disassembly through the integrated injection molding and anti-slip texture design of the screwing position 1; and it achieves universal compatibility between French and American air nozzles through the design of the integrated dual-purpose adapter 9. Through the selection of materials and structural design of the flexible hose, excellent operational flexibility and durability are achieved. This device demonstrates good applicability and convenience in scenarios such as cycling, outdoor camping, and electric vehicle tire inflation, exhibiting significant practical value.

[0032] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
