[0002] In numerous fields such as outdoor recreation, water sports, and emergency rescue, air cushions play an irreplaceable role as an essential auxiliary device. For example, in outdoor camping, air cushions provide a comfortable sleeping environment; in water sports, they serve as buoyancy tools to ensure safety; and in emergency rescue scenarios, they can be used to temporarily construct shelters or rescue the injured. However, the proper use of air cushions relies on stable, efficient, and convenient inflation equipment. Traditional inflation methods and air pumps have many drawbacks and can no longer meet the growing demand. Therefore, a backpack-style rechargeable air pump for inflating air cushions is provided. Utility Model Content
[0003] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a backpack-type charging air pump for inflating air cushions.
[0004] To achieve the above objectives, the present invention provides a backpack-type inflatable air pump for air cushions, comprising a pump body with a handle on the pump body; it also includes a shoulder strap, and a connecting component is provided on the pump body, with the shoulder strap mounted on the pump body via the connecting component; the connecting component includes a first piece mounted on the pump body, with the shoulder strap mounted on the pump body via the first piece.
[0005] Preferably, the pump body has a first groove for accommodating the first piece. The first piece, made of rigid material, is bent to form a protrusion with a groove. The end of the protrusion does not protrude from the free end face of the pump body. The first groove provides installation space for the first piece, allowing it to be stably installed on the pump body. The bending of the rigid first piece to form a protrusion with a groove, with the end not protruding from the free end face of the pump body, ensures the compactness of the structure and facilitates subsequent connection with the shoulder strap. This achieves a stable connection between the first piece and the pump body, providing a reliable foundation for the installation of the shoulder strap. At the same time, it avoids the inconvenience and safety hazards caused by the protrusion, making the entire connection assembly more reasonable and practical.
[0006] Preferably, the shoulder strap is provided with a second ring body, and a buckle body is rotatably provided on the second ring body. The shoulder strap is set on the protrusion through the buckle body. The second ring body and the rotatably provided buckle body make the connection between the shoulder strap and the protrusion body more flexible. The buckle body can rotate relative to the second ring body, which makes it easy to adjust the angle of the shoulder strap, and realizes the flexibility and adjustability when the shoulder strap is connected to the pump body.
[0007] Preferably, a first ring is rotatably mounted on the protrusion. The first ring is formed by bending a rigid material and is D-shaped. The buckle is used to hang on the first ring. The rotatable first ring provides a hanging point for the buckle. The D-shaped design makes the buckle hanging more stable. At the same time, the rigid material ensures the strength and durability of the first ring, realizing a stable and flexible connection between the strap and the protrusion. The D-shaped structure prevents the buckle from easily falling off, ensuring the reliability of the connection between the strap and the pump body. The rotatable design also facilitates the installation and removal of the strap.
[0008] Preferably, the pump body also has a second groove that communicates with the first groove. The second groove is located at the end of the pump body near the protrusion. The second groove communicates with the first groove, providing more space and support for the installation of the first piece and the protrusion. At the same time, the position close to the protrusion helps to avoid the protrusion from being overly restricted to the pump body, which could cause discomfort to the user. This allows for a more stable installation of the first piece on the pump body, further improving the overall stability of the connecting components. This makes the connection between the strap and the pump body more reliable and reduces the inconvenience and risks caused by loose connections.
[0009] Preferably, the cross-sections of the first and second grooves are trapezoidal. The trapezoidal cross-section design allows the first piece to fit better with the groove during installation, facilitating the installation and removal of the connecting components, increasing the contact area, improving the stability of the connection, achieving a tighter connection between the first piece and the pump body, effectively preventing the first piece from shaking in the groove, improving the durability and reliability of the connecting components, and ensuring the stability of the connection between the strap and the pump body.
[0010] Preferably, the first plate is mounted on the pump body by external bolts. This external bolt fixing method makes the connection between the first plate and the pump body more secure, facilitates installation and disassembly, and achieves a reliable and detachable connection between the first plate and the pump body. This allows for easy maintenance or replacement of the connection components when needed, improving the maintainability and service life of the product.
[0011] Preferably, both ends of the carrying strap are equipped with connecting components. These components allow the carrying strap to be more stably connected to the pump body, distributing the pulling force exerted by the pump body on the carrying strap and improving carrying comfort. This achieves a more stable and balanced connection between the pump body and the carrying strap, preventing the carrying strap from breaking or slipping due to excessive force on one end, thus ensuring the user's safety and comfort when carrying the air pump.
[0012] Preferably, the carrying strap includes a strap body and an adjustment component disposed on the strap body. The adjustment component is used to adjust the effective length of the strap body acting on the human body. The strap body provides basic carrying functions. The adjustment component can adjust the length of the strap body according to the body size and needs of different users, realizing the adaptability of the carrying strap to different users. Users can adjust to a suitable carrying length according to their height, body type and other factors, improving the comfort and convenience of carrying, and making it easier for more people to use the air pump.
[0013] Preferably, a pad is also provided on the pump body. The pad is located at the bottom of the pump body. The pad is located at the bottom of the pump body, which can increase the friction between the pump body and the placement surface and play a buffering role. This can realize the stability of the pump body when it is placed and prevent the pump body from sliding during the placement process. At the same time, the buffering effect can reduce the impact force when the pump body collides with the placement surface, protect the pump body from damage, and extend the service life of the product.
[0014] The beneficial effects of this utility model are as follows: The handle allows users to easily operate the air pump by hand. When close-range operation is required or carrying it on a shoulder strap is inconvenient, the user can directly hold the handle for inflation. The shoulder strap and connecting components allow the air pump to be carried like a backpack, reducing hand strain and making it convenient for users to carry the air pump while moving. This diversifies the air pump's operation methods, allowing users to flexibly choose between handheld or shoulder carrying depending on the usage scenario. This improves the flexibility and convenience of air pump use. For users who need to use the air pump for extended periods or move around a large area, the shoulder carrying method greatly reduces hand fatigue and improves work efficiency.
