Description

Technical Field

[0001] This application relates to the field of inflatable tent or canopy technology, and more specifically to a connection structure for an air column and an air pump. Background Technology

[0002] Inflatable column tents, as a rapidly developing innovative category of outdoor equipment in recent years, have become a popular choice for outdoor enthusiasts and family camping scenarios due to their convenient setup and stable structural performance. Their core technology lies in replacing the traditional frame with an air pressure support system, and the crucial inflatable connection process is particularly noteworthy.

[0003] Currently, mainstream products mainly adopt an external inflation system: inflation is performed through an external interface using an electric / manual air pump.

[0004] In the implementation of the external inflation system, the connecting structure is welded to the air column and then connected to the connector on the air pump through a threaded structure. Since the connecting structure is made of PE material, it has low rigidity and is easily deformed under the action of air pressure inside the air column, which leads to irregular deformation of the threaded structure. Furthermore, when the electric air pump is connected to the connector on the air pump through the threaded connection, it is easy to strip the thread, which affects the airtightness and stability of the connection between the connecting structure and the air pump.

[0031] Reference Figure 1-5 This application proposes an embodiment of the connection structure between the air column and the air pump, which includes:

[0032] Connector 10 is used for a sealed connection with air column 50.

[0033] The connecting member 20 is connected to and sealed to the connecting seat 10, and the connecting member 20 is provided with a connector 21 and an air hole 22.

[0034] The rigidity of the connecting member 20 is greater than that of the connecting seat 10.

[0035] This application divides the connection structure for the air column and the air pump into two parts: a connecting seat 10 and a connecting member 20, which are interconnected and sealed in contact. The connecting seat 10 is connected to and sealed with the air column 50, and the connecting member 20 is sealed to the air pump 60. The air pump can pump or inflate the air column 50 through the air hole 22. The rigidity of the connecting member 20 is greater than that of the connecting seat 10, that is, the deformation resistance of the connecting member 20 is greater than that of the connecting seat 10. Even if the connecting seat 10 deforms under the action of air pressure inside the air column, the connector 21 on the connecting member 20 will not deform under the action of the connecting seat 10 and affect the connection with the air pump 60, thereby ensuring the stability and airtightness of the connection structure of this application with the air pump 60.

[0036] The connector 21 is connected to the air column 50 through the air hole 22. The connector 21 can be connected to an air pump so that the air pump installed on the connector 21 can pump or inflate the air column 50 through the air hole.

[0037] In this embodiment, the connecting seat 10 is provided with a mounting hole 12 communicating with the air column 50. The connecting member 20 extends into the mounting hole 12, and a sealing ring 30 is provided between the connecting member 20 and the mounting hole 12 to achieve a seal. At the same time, the connecting head 21 communicates with the air column 50 through the air hole 22. Referring to the accompanying drawings, the connecting member 20 and the mounting hole 12 are sealed by an O-ring radial seal to ensure that the compressed air in the air column does not leak.

[0038] Preferably, the connecting seat 10 has a pressure plate 13 that protrudes toward the air column 50. In this embodiment, the connecting seat 10 has a pressure plate 13 distributed between the mounting hole 12 and the air column 50. When the pressure plate 13 bears the air pressure in the air column, the pressure can be dispersed radially along the pressure plate 13, which helps to reduce the deformation of the pressure plate 13 after bearing the air pressure.

[0039] Furthermore, multiple reinforcing ribs 14 are provided on one or both sides of the pressure plate 13. These reinforcing ribs 14 are evenly distributed along the outer periphery of the mounting holes, further improving the pressure-bearing strength of the pressure plate 13 and helping to further reduce the deformation of the pressure plate 13 under air pressure. The reinforcing ribs 14 can be provided on one or both sides of the pressure plate 13; referring to the attached drawings, both sides of the pressure plate 13 are provided with the reinforcing ribs 14.

[0040] Preferably, the outer side of the connecting seat 10 is provided with a wall 15 for connecting with the air column 50. When the air column 50 is welded to the connecting seat 10, it is beneficial to increase the contact area between the connecting seat and the air column and ensure the connection stability.

[0041] In this embodiment, the connector 21 is provided with a threaded structure for connecting with the air pump 60. In this embodiment, the connector 21 and the housing of the air pump 60 are made of the same material. When the connector 21 and the housing of the air pump 60 are threadedly connected, stripping is avoided, and the two can be screwed together and locked to achieve a stable connection and seal.

[0042] In this embodiment, the air pump housing is made of ABS material, and the connector 21 is also made of ABS material.

[0043] Accordingly, the connecting seat 10 is preferably made of PE material, which is the same material as the air column 50, and the wall 15 of the connecting seat 10 and the air column 50 can be connected by welding to form a sealed connection.

[0044] Referring to the accompanying drawings, the connecting seat 10 and the connecting member 20 are stably connected to each other by fasteners. Specifically, the connecting member 20 passes through the mounting hole 12 and is provided with an outward flange 23. The outward flange 23 is provided with a through hole 24. The connecting seat 10 is provided with a column 16, which is provided with a first threaded hole. The fastener passes through the through hole 24 and is screwed into the first threaded hole.

[0045] In one embodiment, the connector can be connected to an air pump to evacuate the air column.

[0046] In another embodiment, the connector can be connected to an air pump 60. When the air pump 60 inflates the air column, a one-way valve structure 40 is provided at the air hole 22. The one-way valve structure 40 means that the air pump 60 can inflate the air column from the air hole 22, while preventing the gas in the air column from escaping from the air hole 22.

[0047] In this embodiment, the one-way valve structure 40 includes a sealing diaphragm and a fixing post. The connecting seat 10 is provided with a small hole. The fixing post is installed in the small hole and makes the sealing diaphragm contact the connecting seat 10 and cover the air hole 22.

[0048] When the air pump 60 is connected to the connecting structure and inflates the air column, the sealing diaphragm deforms under the action of the airflow and opens the air hole 22, allowing gas to flow into the air column from the air hole 22. When inflation stops, the sealing diaphragm, under the action of the air pressure inside the air column, adheres tightly to the sealing part, thereby covering the air hole 22 and preventing air from escaping from the air hole 22. Those skilled in the art should understand that the sealing diaphragm is made of a flexible material so that it can adhere tightly to the sealing part under air pressure and can also deform under the action of airflow to open the air hole 22.

[0049] In this embodiment, the fixing post is also made of flexible material. The fixing post is provided with a limiting protrusion. The fixing post is inserted into a small hole. The limiting protrusion is used to limit the fixing post in the small hole so that the sealing diaphragm covers the air hole 22, and prevents the fixing post from coming out of the small hole under the action of the airflow injected by the air pump 60.

[0050] The air holes 22 are provided in multiple ways, and the multiple air holes 22 are distributed at intervals around the mounting hole 12, which helps to improve the inflation speed of the air column.

[0051] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
