Description

Technical Field

[0001] This utility model belongs to the technical field of inflatable products, specifically relating to an air nozzle connector for air exchange between inflatable products. Background Technology

[0002] Most existing inflatable products are single-unit structures, requiring individual inflation of each product before they can be combined for use. However, this increases the workload for staff as the number of inflatable products increases, causing inconvenience.

[0003] To address the issue of using multiple inflatable products in combination, prior art with publication number CN222329538U discloses an air guiding structure for connecting two inflatable products. This solution employs a first connector and a second connector, so that the first air hole and the second air hole form an airflow channel between the two inflatable products, thereby solving the problem that existing vehicle-mounted inflatable mattresses cannot simultaneously achieve both user comfort and convenient inflation / deflation.

[0004] However, in the above structure, the first and second connectors are maintained by the squeezing force of the inflatable products. When the mattress shakes, the connection is prone to instability and air leakage. It is necessary to design an air nozzle connector that enables stable connection between multiple inflatable products. Utility Model Content

[0005] To address the aforementioned problems in the existing technology, this solution provides an air nozzle connector for air exchange between inflatable products.

[0006] The technical solution adopted in this utility model is as follows:

[0007] An air nozzle connector for air exchange between inflatable products includes a first connector and a second connector;

[0008] The two inflatable products connected by the air nozzle connector each have a first air nozzle and a second air nozzle; both the first air nozzle and the second air nozzle have threads.

[0009] The first connecting body of the first connector is in the shape of a tube, and both ends of the first connecting body are threaded, namely a first threaded end and a first plug-in end; the first threaded end is used to thread-connect the first air nozzle, and the first plug-in end is used to connect the second connector.

[0010] The second connector includes a second connecting body and an internally threaded collar; the second connecting body is in the shape of a tube, and its two ends are a second threaded end and a second insertion end, respectively; the second threaded end is used to thread-connect the second air nozzle, and the second insertion end is used to insert into the first insertion end; the internally threaded collar is rotatably connected to the outside of the second insertion end, one end of the internally threaded collar is engaged in the collar mounting groove of the second insertion end, and the internally threaded collar is used to thread-connect the first insertion end.

[0011] As an alternative or supplement to the above structure: the middle part of the first connecting body has a first convex ring, the end face of the first convex ring has a first annular groove, and a first axial sealing ring is installed in the first annular groove. The first axial sealing ring is used for sealing between the first connector and the first air nozzle.

[0012] As an alternative or supplement to the above structure: the middle part of the second connecting body has a second convex ring, the end face of the second convex ring has a second annular groove, and a second axial sealing ring is installed in the second annular groove. The second axial sealing ring is used for sealing between the second connector and the second air nozzle.

[0013] As an alternative or supplement to the above structure: a sealing ring mounting groove is provided on the outer wall of the second plug end, and a radial sealing ring is installed in the sealing ring mounting groove; when the second plug end is inserted into the first plug end, the radial sealing ring seals both of them.

[0014] As an alternative or supplement to the above structure: both the first and second air nozzles are valves, the valves including a valve body and a valve core disc; the valve body is provided with a channel for fluid to pass through; the valve core disc is provided with a through hole, and a one-way diaphragm is provided on one side of the valve core disc, the one-way diaphragm is used to seal the through hole in one direction, so that the valve core disc seals the channel in one direction.

[0015] The cross-section of the channel and the valve core disc are both circular, square, or elliptical. An annular groove is provided on the outer circumferential surface of the valve core disc along the extending direction of the outer circumferential surface. A sealing ring is provided in the annular groove. The sealing ring is interference-fitted with the side wall of the channel to fill the gap between the valve core disc and the side wall of the channel, and to make the valve core disc flip relative to the valve body.

[0016] As an alternative or supplement to the above structure: both the first and second air nozzles are connected to air nozzle plugs via a hanging rope, and the air nozzle plugs can be threadedly connected to the first or second air nozzle.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. The air nozzle connector in this solution can connect two adjacent air nozzles when multiple inflatable products are used in combination, so that the inflatable products can be interconnected. When one inflatable product is inflated, the other inflatable products can also be inflated, thus bringing convenience to the staff.

[0019] 2. In the structure of this solution, when the three connection points of the first air nozzle and the first connector, the second air nozzle and the second connector, and the first connector and the second connector are connected, they can be tightened independently, thereby avoiding the three connection points from interacting with each other and affecting the airtightness.

Detailed Implementation

[0026] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only a part of the embodiments, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments in this solution without creative effort are within the protection scope of this solution.

[0027] like Figures 1 to 4 As shown in the figure, this embodiment designs an air nozzle connector for air exchange between inflatable products.

[0028] The inflatable products covered in this solution include one or more air nozzles. Some air nozzles are used to connect to adjacent inflatable products, while others are used to connect to inflation equipment, air pumps, or to close directly. Air nozzles with one-way valves are readily available on the market. Details are not provided here.

[0029] The two inflatable products connected by the air nozzle connector have a first air nozzle 1 and a second air nozzle 4 respectively; both the first air nozzle 1 and the second air nozzle 4 have threads; the air nozzle connector is threadedly connected to the first air nozzle 1 and the second air nozzle 4.

[0030] The first connector 2 includes a first connecting body 22 and a first axial sealing ring 21.

[0031] The first connecting body 22 is in the shape of a tube. Both ends of the first connecting body 22 have external threads. The two ends of the first connecting body 22 are a first threaded end 221 and a first plug-in end 222, respectively. The first threaded end 221 is used to thread-connect the first air nozzle 1, and the first plug-in end 222 is used to connect the second connector 3.

[0032] The first connecting body 22 has a radially outwardly protruding first convex ring 223 at its center. The end face of the first convex ring 223 has a first annular groove 224. A first axial sealing ring 21 is installed within the first annular groove 224, and the first axial sealing ring 21 is used for sealing between the first connector 2 and the first air nozzle 1. The outer ring wall of the first convex ring 223 has anti-slip textures to facilitate manual rotation of the first connecting body 22 to tighten the first connector 2 onto the first air nozzle 1.

[0033] The second connector 3 includes components such as a second connecting body 33, an internal threaded collar 32, and a second axial sealing ring 34.

[0034] The second connecting body 33 is tubular in shape, with a second threaded end and a second insertion end 331 at its two ends. The second threaded end has an external thread and is used for threaded connection to the second air nozzle 4. The second insertion end 331 is used to insert into the first insertion end 222. The internally threaded collar 32 is rotatably connected to the outside of the second insertion end 331. One end of the internally threaded collar 32 is engaged in the collar mounting groove 334 of the second insertion end 331, allowing the internally threaded collar 32 to rotate freely relative to the second insertion end 331 without axial movement. The internally threaded collar 32 has an internal thread to facilitate threaded connection to the first insertion end 222.

[0035] The second connecting body 33 has a second convex ring 332 in the middle, and a second annular groove on the end face of the second convex ring 332. A second axial sealing ring 34 is installed in the second annular groove, and the second axial sealing ring 34 is used for sealing between the second connector 3 and the second air nozzle 4. The outer ring wall of the second convex ring 332 has anti-slip texture to facilitate manual rotation of the second connecting body 33 to tighten the second connector 3 onto the second air nozzle 4.

[0036] The outer wall of the second plug end 331 is provided with a sealing ring mounting groove 333, and a radial sealing ring 31 is installed in the sealing ring mounting groove 333; when the second plug end 331 is inserted into the first plug end 222, the radial sealing ring 31 seals both of them.

[0037] When the one-way valve in the second air nozzle 1 is opened, the inflation product where the first air nozzle 1 is located is connected to the cavity of the first connecting body 22 in one direction. At the same time, the cavity of the second connecting body 33 is connected to the inflation product where the second air nozzle 4 is located, so that the first air nozzle 1 can supply air to the second air nozzle 2.

[0038] Both the first air nozzle 1 and the second air nozzle 4 are connected to air nozzle plugs 5 via a hanging rope. The air nozzle plugs 5 can be threadedly connected to the first air nozzle 1 or the second air nozzle 4. Thus, after disassembling the air nozzle connector, the air nozzle plugs 5 can be used to block the corresponding air nozzle, thereby enabling the inflatable product to be used independently.

[0039] The first air nozzle 1 and the second air nozzle 4 can adopt the valve with publication number CN107101024A. Specifically, the valve includes a valve body and a valve core disc; the valve body is provided with a channel for fluid to pass through; the valve core disc is disposed in the channel and rotates relative to the valve body; the valve core disc is provided with a through hole, and a one-way diaphragm is provided on one side of the valve core disc for one-way sealing of the through hole, so that the valve core disc one-way seals the channel. Since the valve core disc can rotate relative to the valve body, it realizes the one-way charging and discharging function, and when discharging, rotating the valve core disc opens the channel to release air, and the user can adjust the discharging speed by rotating the valve core disc. This valve is not only simple in structure, but also convenient for users to discharge air.

[0040] The above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation; it is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom remain within the scope of this technology.
