[0030] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. The following text is only used to describe one or several specific implementations of the present invention and does not strictly limit the scope of protection specifically claimed by the present invention.

[0031] The quick installation and removal mechanism of the oxygen concentrator provided by the present invention is explained below with reference to the accompanying drawings.

[0032] The utility model provides a quick installation and disassembly mechanism, see Figure 1 It is mainly composed of a transition plate 1, a pin 2, a hexagonal self-locking nut 3, a base plate 4, a rear internal thread 5, a front internal thread 6, a limiting step 7 and a sleeve component 8.

[0033] The transition plate 1 is flat and fixed on the aircraft. A tail boss is provided at the tail end. A rear threaded hole is provided on the tail boss. A rear internal thread 5 is provided in the rear threaded hole for fixing the tail end of the latch 2. A ball head is provided on the top of the latch 2.

[0034] A front threaded hole is provided at the front end of the transition plate 1, and a front internal thread 6 is provided in the front threaded hole for limiting and fixing the oxygen concentrator after it is installed in place;

[0035] Limiting steps 7 are provided on both sides of the bottom plate 4 of the oxygen concentrator. A sleeve component 8 matching the latch 2 is provided at the rear end of the bottom plate 4, and a positioning hole is provided at the front end.

[0036] The limiting steps 7 are provided on both sides of the transition plate 1 to guide the direction during the loading and unloading of the oxygen concentrator.

[0037] After the base plate 4 of the oxygen concentrator is pushed into place toward the rear, the sleeve component 8 is sleeved on the outside of the ball head of the latch 2, the positioning hole overlaps with the front internal thread 6, and the base plate 4 of the oxygen concentrator is connected to the transition plate 1 by screws passing through the front threaded hole and the positioning hole.

[0038] Optionally, the ball head of the latch pin 2 has a diameter of 10 mm and a length of 10 mm.

[0039] Optionally, the number of the latches 2 is two.

[0040] Optionally, it also includes: a hexagonal self-locking nut 3;

[0041] The hexagonal self-locking nut 3 is sleeved on the portion of the latch pin 2 that extends beyond the tail boss.

[0042] Optionally, reinforcing ribs are provided on the transition plate 1 .

[0043] Optionally, the diameter of the ball head of the latch pin 2 is larger than the diameter of the tail thread section.

[0044] Optionally, the clearance between the ball head diameter of the latch pin 2 and the inner diameter of the sleeve component 8 is less than 0.5 mm.

[0045] The features of transition plate 1 are detailed in Figure 2 、 Figure 4 and Figure 5 The rear boss has a rear internal thread 5 for securing the latch 2, and the front flat surface has a front internal thread 6 for securing the oxygen concentrator in place. Multiple reinforcing ribs are also located in the center of the transition plate to ensure the strength of the connection between the oxygen concentrator and the mounting plate.

[0046] The characteristics of pin 2 are detailed in Figure 3 Made of stainless steel, it has stable physical and chemical properties. It is primarily secured to the rear boss of the transition plate 1 via its threaded section, and its front spherical head engages with the sleeve 8 on the oxygen concentrator base plate 4 to limit and secure the product.

[0047] The features of the bottom plate 4 are detailed in Figure 6 and Figure 7 The base plate is machined with limit steps 7 on both sides, and a sleeve component 8 at the rear end. The limit steps primarily engage with the sides of the transition plate 1, providing guidance during product loading and unloading. Once the oxygen concentrator is pushed inward, the sleeve component 8 engages with the front ball end of the latch 2 on the transition plate 1 and secures the product in place via screws threaded through the front threaded holes and locating holes.

[0048] The overall concept behind this quick-release mechanism is that a stopper step 7 secures the oxygen concentrator's movement on the transition plate 1, preventing it from being positioned in inaccessible spaces. After the product is pushed into place and snapped into place with the latch 2, the screws in the pre-threaded and locating holes are tightened to complete the assembly. Disassembly requires only removing the two outer screws and pulling the entire product out, eliminating the need for traditional mounting methods to remove all inner screws before moving the product. This mechanism is ideal for use in unusually shaped spaces where access is limited.

[0049] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
