Description

Technical Field

[0001] This utility model belongs to the technical field of inflatable products, specifically relating to a connecting component for two inflatable products. Background Technology

[0002] Chinese patent CN222329538U discloses an air-guiding structure for connecting two inflatable products, including a first connector and a second connector. The first connector is disposed on one of the inflatable products and has a first air hole communicating with that inflatable product. The second connector is disposed on the other inflatable product and has a second air hole for fluid to pass through. The first connector is removably and sealingly connected to the second connector, such that the first and second air holes form an airflow channel between the two inflatable products. This solves the problem in existing vehicle-mounted inflatable mattresses where it is difficult to balance user comfort and ease of inflation / deflation.

[0003] However, actual testing revealed that this air-guiding structure, when applied to inflatable products, poses a risk of air leakage, reducing inflation speed and increasing inflation time. Furthermore, due to the insufficiently tight connection between the air-guiding structure and the inflatable product, there is a risk of detachment, hindering smooth inflation.

[0004] To address the issues of air leakage and detachment in the air-conducting structure of existing in-vehicle inflatable mattresses, a more reasonable solution is needed to resolve these technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a connecting component for two inflatable products to solve the problems of easy air leakage and detachment in the air guiding structure of existing vehicle-mounted inflatable mattresses.

[0006] To achieve the above objectives, this utility model provides a connecting assembly for two inflatable products, including an air bed connector, a foot pedal connector, and a sleeve. The air bed connector is disposed on one of the inflatable products, the wing plate of the foot pedal connector is connected to the other inflatable product, and the foot pedal connector is used to be inserted into the sleeve.

[0007] The air bed connector has a limiting ring on its cylindrical column; the foot pedal connector includes a main cylinder with a first end and a second end opposite to each other. The first end of the main cylinder has a wing plate for limiting the movement of the foot pedal connector; the second end of the main cylinder has a stop plate for limiting the position of the sleeve; the inner hole of the main cylinder has a limiting groove that cooperates with the limiting ring, the cylindrical column of the air bed connector is embedded in the main cylinder, and the limiting ring is embedded in the limiting groove.

[0008] In one possible design, the connecting assembly further includes a spacer sleeve fitted onto the cylindrical column and inserted into the main cylinder; the spacer sleeve is connected to the cylindrical column and the main cylinder respectively via a wire drawing structure.

[0009] In one possible design, the wire drawing structure includes a wire drawing ring and a wire drawing groove. The inner wall of the spacer is provided with the wire drawing groove to engage the limiting ring; the outer wall of the spacer is provided with a wire drawing ring to engage the limiting groove.

[0010] In one possible design, the outer contour of the limiting ring is arc-shaped.

[0011] In one possible design, multiple limiting rings are provided and spaced apart along the axial direction of the cylinder, wherein the second end of the foot pedal connector is provided with the limiting ring.

[0012] In one possible design, the wing plate is integrally formed with the main tube.

[0013] In one possible design, multiple stop blocks are provided and spaced apart along the circumferential direction of the main cylinder, wherein the contact surfaces of the stop blocks and the sleeve are both planar.

[0014] In one possible design, the air bed connector includes an annular plate and a hollow cylindrical column, the annular plate being used to abut against the wing plate, and the edges of the annular plate and the wing plate being flush.

[0015] In one possible design, the ring plate and the cylindrical column are integrally formed.

[0016] In one possible design, the cylinder has vents at both ends for gas flow.

[0017] In one possible design, both ends of the cylinder are closed ends.

[0018] In one possible design, the side of the cylinder closest to the annular plate is a closed end, and the side furthest from the annular plate is an open end.

[0019] The above technical solution creates an airflow channel between the air mattress and the inflatable foot pedals, enabling integrated inflation. This simplifies the inflation process, eliminating the need to inflate each product separately, thus improving inflation efficiency and saving time and labor costs. Furthermore, it solves the problem of cumbersome assembly of different inflatable products. Previously, connecting different products might have required complex tools or tedious procedures. This connecting component, with its simple structure and the use of limiting rings and grooves, allows for quick, accurate, and stable connection of two inflatable products. Users can easily assemble them according to their needs; for example, when camping outdoors, the air mattress and inflatable foot pedals can be easily connected, enhancing the user experience and product practicality. The air mattress connector and the foot pedal connector are connected by a limiting ring and a limiting groove, and the foot pedal connector's upper wing plate and stop plate limit the position of itself and the sleeve. This ensures that the two inflatable products have good stability after connection, and are not easy to loosen or fall off. During use, they can maintain a good connection and ensure the normal use of the products. For example, when resting, the air mattress and inflatable foot pedal will not affect comfort or cause accidents due to unstable connection. Attached Figure Description

Detailed Implementation

[0038] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that while the description of these embodiments is intended to aid in understanding the present invention, it does not constitute a limitation thereof. The specific structural and functional details disclosed herein are only for describing exemplary embodiments of the present invention. However, the present invention may be embodied in many alternative forms and should not be construed as being limited to the embodiments described herein.

[0039] According to a specific embodiment of this utility model, a connecting component for two inflatable products is provided, which can respectively connect an air mattress 4 and an inflatable foot pedal 5. In one embodiment, an airflow channel can be established between the air mattress 4 and the inflatable foot pedal 5, thereby achieving integrated inflation; alternatively, two purely inflatable products can be connected to achieve integrated inflation, thus solving the problem of cumbersome assembly of different inflatable products. Figures 1 to 16 Several specific implementation examples of this connecting assembly for two inflatable products are shown.

[0040] See Figures 1 to 16 As shown, the connecting assembly for two inflatable products includes an air bed 4 connector, a foot pedal connector 2, and a sleeve 3. The air bed 4 connector is disposed on one of the inflatable products, and the wing plate 23 of the foot pedal connector 2 is connected to the other inflatable product. The foot pedal connector 2 is used to insert into the sleeve 3. A limiting ring 11 is provided on the cylindrical column 12 of the air bed 4 connector. The foot pedal connector 2 includes a main cylinder 22, which has a first end and a second end. The first end of the main cylinder 22 is provided with a wing plate 23, which is used to limit the movement of the foot pedal connector 2. The second end of the main cylinder 22 is provided with a stop 24 to limit the position of the sleeve 3. A limiting groove 21 that cooperates with the limiting ring 11 is provided in the inner hole of the main cylinder 22. The cylindrical column 12 of the air bed 4 connector is embedded in the main cylinder 22, and the limiting ring 11 is embedded in the limiting groove 21.

[0041] The working principle of this connecting assembly is as follows: the connecting assembly connects two inflatable products through the mutual cooperation between the air bed 4 connector, the foot pedal connector 2, and the sleeve 3. The air bed 4 connector is fixed to one of the inflatable products (such as air bed 4). The foot pedal connector 2 has a cylindrical structure, and the limiting groove 21 in its inner hole cooperates with the limiting ring 11 on the outer periphery of the air bed 4 connector. When the air bed 4 connector is inserted into the inner hole of the foot pedal connector 2, the limiting ring 11 is inserted into the limiting groove 21, thereby fixing the relative position of the two in the axial or radial direction and ensuring the stability of the connection. At the same time, the foot pedal connector 2 is installed on another inflatable product (such as inflatable foot pedal 5). The sleeve 3 provides support and positioning for the foot pedal connector 2. The wing plate 23 and the stop plate 24 on the foot pedal connector 2 further restrict the movement of the foot pedal connector 2 itself and limit the position of the sleeve 3, so that the entire connecting assembly can stably connect the two inflatable products.

[0042] During operation, firstly, install the air bed 4 connector onto one of the inflatable products, such as the air bed 4, ensuring it is properly positioned and securely fixed. Specifically, connect the ring plate 13 on the air bed 4 connector to the air bed 4. Connect the wing plate 23 of the foot pedal connector 2 to the foot pedal of the air bed 4, ensuring the foot pedal connector 2 is inserted into the inner hole of the sleeve 3. At this point, the stop plate 24 on the foot pedal connector 2 contacts the sleeve 3, determining the position of the sleeve 3 on the foot pedal connector 2. Simultaneously, the wing plate 23 at the first end of the foot pedal connector 2 is in its natural state, used to restrict its subsequent movement. Connect the air bed 4 with the air bed 4 connector installed to another inflatable product (such as an inflatable foot pedal) with the foot pedal connector 2 assembled. Embed the air bed 4 connector into the inner hole of the foot pedal connector 2, ensuring the limiting ring 11 on the outer periphery of the air bed 4 connector is accurately embedded into the limiting groove 21 in the inner hole of the foot pedal connector 2, thus completing the connection between the two inflatable products. If airflow is required to achieve integrated inflation, ensure that the airflow channels inside the air mattress 4 connector and the foot pedal connector 2 are interconnected.

[0043] The above technical solution enables the formation of an airflow channel between the air mattress 4 and the inflatable foot pedals 5, achieving integrated inflation. This simplifies the inflation process, eliminating the need to inflate each product separately, thus improving inflation efficiency and saving time and labor costs. Furthermore, it solves the problem of cumbersome assembly of different inflatable products. Previously, connecting different products might have required complex tools or tedious procedures. This connecting component, with its simple structure and the cooperation of limiting rings 11 and limiting grooves 21, allows for quick, accurate, and stable connection of two inflatable products. This facilitates user assembly according to their needs; for example, when camping outdoors, the air mattress 4 and inflatable foot pedals 5 can be easily connected, enhancing the user experience and product practicality. The air mattress 4 connector and the foot pedal connector 2 are connected by a limiting ring 11 and a limiting groove 21, and the foot pedal connector 2's upper wing plate 23 and stop plate 24 limit the position of itself and the sleeve 3. This ensures that the two inflatable products have good stability after connection, are not easy to loosen or fall off, and can maintain a good connection during use, ensuring the normal use of the products. For example, when resting, the air mattress 4 and the inflatable foot pedal 5 will not affect comfort or cause accidents due to unstable connection.

[0044] For products like filament mattresses that require maintaining a specific air pressure to ensure comfort, good sealing performance is essential. Therefore, the connecting assembly also includes a spacer 6, which is fitted onto the cylinder 12 and inserted into the main cylinder 22. The spacer 6 is connected to both the cylinder 12 and the main cylinder 22 via a filament structure. Because the spacer 6 is connected to the cylinder 12 and the main cylinder 22 via a filament structure, this not only enhances the connection strength between the components but also effectively distributes pressure, preventing damage or deformation caused by excessive localized stress. The spacer 6 with its filament structure is easier to position and install, reducing the complexity of the assembly process. This design allows even non-professional users to easily assemble the inflatable product, improving the user experience.

[0045] The design of the spacer 6 allows for smooth air flow between the cylinder 12 and the main cylinder 22, ensuring the continuity and efficiency of the entire inflation system. For brushed mattresses, this allows for more even airflow distribution, ensuring a more balanced pressure distribution on the mattress surface and improving comfort. Thus, by optimizing the airflow path, the internal air distribution of the brushed mattress is made more uniform, avoiding areas that are too firm or too soft, providing a more comfortable sleep experience.

[0046] In one possible design, the wire drawing structure includes a wire drawing ring 61 and a wire drawing groove. The inner wall of the spacer 6 is provided with the wire drawing groove to engage the limiting ring 11. The outer wall of the spacer 6 is provided with a wire drawing ring 61 to engage the limiting groove 21.

[0047] The wire drawing groove is located on the inner wall of the spacer 6. Its function is to hold the limiting ring 11 on the cylinder 12, so that the spacer 6 and the cylinder 12 can be tightly connected, preventing the spacer 6 from sliding or rotating axially during use, thereby ensuring the stability of the entire connection assembly.

[0048] A draw ring 61 is located on the outer wall of the spacer 6 and is used to engage with the limiting groove 21 inside the main cylinder 22. The design of the draw ring 61 allows the spacer 6 to be securely inserted into the main cylinder 22 and achieves precise positioning through its engagement with the limiting groove 21. This ensures a good connection even under frequent use or external impact.

[0049] In use, first, the spacer 6 with the wire-drawing groove is fitted onto the cylinder 12, ensuring that the limiting ring 11 is correctly embedded in the wire-drawing groove. Then, the spacer 6, together with the cylinder 12, is inserted into the main cylinder 22. At this time, the wire-drawing ring 61 on the outer wall of the spacer 6 will fit tightly with the limiting groove 21 inside the main cylinder 22, completing the final connection. This ensures that the airflow channel between the air mattress 4 and the inflatable foot pedal 5 is unobstructed, while providing excellent stability and sealing, offering users a comfortable and reliable user experience.

[0050] It should be noted that the term "and / or" in this article is merely a description of the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, B exists alone, and A and B exist simultaneously.

[0051] In one embodiment provided in this disclosure, the outer contour of the limiting ring 11 is arc-shaped. The arc-shaped outer contour design of the limiting ring 11 makes the fit between the limiting ring 11 and the limiting groove 21 tighter, which can effectively prevent relative movement between the air mattress 4 connector and the foot pedal connector 2, thereby enhancing the stability of the entire connection assembly and ensuring that the two inflatable products will not affect the use effect due to loose connection during use.

[0052] The tight fit between the arc-shaped limiting ring 11 and the limiting groove 21 effectively reduces gaps at the connection point and improves the sealing performance of the connecting components. This is especially important for integrated inflation functions that require airflow channels, effectively preventing gas leakage, ensuring smooth inflation, and improving inflation efficiency. The design of the arc-shaped limiting ring 11 makes the installation and disassembly of the connecting components smoother, reducing jamming caused by loose fits between the limiting ring 11 and the limiting groove 21, thereby optimizing the user experience and making it easier for users to assemble and use inflatable products.

[0053] To improve the anti-detachment effect, multiple limiting rings 11 are provided and spaced apart along the axis of the cylinder 12, effectively preventing the air mattress 4 connector from detaching from the foot pedal connector 2, thereby significantly improving the anti-detachment effect of the connecting assembly. In specific applications, the number and position of the limiting rings 11 can be flexibly adjusted according to actual usage needs and the characteristics of different inflatable products. For example, in scenarios requiring a higher anti-detachment effect, the number of limiting rings 11 can be increased; in cases of limited space or high requirements for connection flexibility, the number of limiting rings 11 can be appropriately reduced or their positions adjusted to meet the needs of different usage scenarios.

[0054] The foot pedal connector 2 is provided with a limiting ring 11 at its second end, which can provide a stronger limiting effect and effectively prevent the air mattress 4 connector from coming off the foot pedal connector 2. This significantly improves the anti-detachment effect of the connecting components and ensures that the two inflatable products maintain a stable connection during use, avoiding accidents caused by loosening or falling off.

[0055] In this disclosure, the wing plate 23 and the main cylinder 22 are integrally molded, making the overall structure of the pedal connector 2 more robust, able to withstand greater external forces and pressures, and less prone to deformation or damage. This improves the service life and reliability of the connecting components, ensuring that the two inflatable products maintain a stable connection during use. The integrally molded wing plate 23 and main cylinder 22 make the pedal connector 2 more concise and aesthetically pleasing, without unnecessary connecting parts or gaps. This not only enhances the overall aesthetics of the product but also reduces problems such as dust and dirt accumulation caused by a complex appearance, facilitating cleaning and maintenance.

[0056] Meanwhile, compared with manufacturing the wing plate 23 and the main tube 22 separately and then assembling them, the one-piece molding process can reduce production steps and processing time, improve production efficiency, and reduce production costs, which is conducive to the large-scale production and application of this connecting component.

[0057] In one embodiment of this disclosure, multiple stop plates 24 are provided and spaced apart along the circumference of the main cylinder 22, wherein the contact surfaces between the stop plates 24 and the sleeve 3 are all planar. This design not only increases the contact area but also improves the anti-detachment effect. This design effectively prevents the sleeve 3 from detaching from the pedal connector 2 during use, ensuring a more stable and reliable connection between the two inflatable products. The arrangement of multiple stop plates 24 makes the contact between the sleeve 3 and the pedal connector 2 more uniform, better distributing the force and enhancing the stability of the entire connection assembly. When subjected to external forces or vibrations during use, the connection assembly can maintain good connection performance and will not easily loosen or shift, improving the reliability and durability of the product.

[0058] In this disclosure, the air mattress 4 connector includes an annular plate 13 and a hollow cylindrical column 12. The annular plate 13 abuts against the wing plate 23, and the edges of the annular plate 13 and the wing plate 23 are flush. This flush edge design between the annular plate 13 and the wing plate 23 ensures a tighter contact between the air mattress 4 connector and the foot pedal connector 2, providing stronger support and restraint, thereby enhancing the stability of the connection. During use, the connection between the two inflatable products is more secure and less prone to loosening or detachment. Simultaneously, it helps improve installation accuracy, ensuring accurate alignment of the air mattress 4 connector and the foot pedal connector 2 during docking, reducing installation errors, and improving the reliability and consistency of the connection.

[0059] Specifically, the ring plate 13 and the cylinder 12 are integrally molded, which makes the overall structure of the air bed 4 connector more robust, able to withstand greater external forces and pressures, and less prone to deformation or damage. This design improves the service life and reliability of the connecting components, ensuring that the two inflatable products maintain a stable connection during use.

[0060] Since the ring plate 13 and the cylinder column 12 are integrally formed, the relative positional relationship between the two can be better guaranteed during installation, improving installation accuracy and reducing problems such as unstable connection or functional failure caused by installation errors.

[0061] In one embodiment of this disclosure, the cylindrical column 12 has air holes 14 at both ends for gas flow. The design of the air holes 14 at both ends of the cylindrical column 12 allows for airflow between the two inflatable products, thus achieving integrated inflation. Users no longer need to inflate the two products separately, simplifying the inflation process, improving inflation efficiency, and saving time and labor costs. Using the inflatable products is also more convenient and faster for users, eliminating the need to carry multiple inflation devices or perform complex inflation operations. Simultaneously, the design of the air holes 14 makes the inflation process smoother, reducing inconvenience caused by uneven inflation or difficulty in inflation, and improving the overall user experience.

[0062] In another embodiment provided in this disclosure, both ends of the cylindrical column 12 are closed ends. It should be noted that the structure of this embodiment is mainly used for connecting two inflatable products rather than for one-piece inflation.

[0063] Specifically, the two ends of the cylinder 12 are closed, which effectively prevents gas leakage from both ends of the cylinder 12 during inflation, ensuring the airtightness of the inflatable product. This design improves the safety and reliability of the inflatable product, avoiding problems such as insufficient inflation or inflation failure due to gas leakage. This simplifies the structural design of the connecting components, reducing unnecessary complex structures and parts. This design makes the connecting components more compact, lightweight, easy to carry and use, while also helping to reduce production costs and improve production efficiency.

[0064] In another embodiment provided in this disclosure, the side of the cylinder 12 closest to the annular plate 13 is a closed end, and the side furthest from the annular plate 13 is an open end. This unidirectional open design allows for better control of the gas flow direction, ensuring that the gas flows along a predetermined path during inflation or deflation. This not only improves the efficiency of inflation and deflation but also reduces inconvenience caused by unclear gas flow direction, enhancing the overall user experience.

[0065] Finally, it should be noted that this utility model is not limited to the above-described optional embodiments, and anyone can derive other various forms of products under the guidance of this utility model. The above specific embodiments should not be construed as limiting the scope of protection of this utility model, which should be determined by the claims, and the description can be used to interpret the claims.
