DETAILED DESCRIPTION

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] like Figure 1 As shown, one embodiment of this utility model provides an oxygen filling device, including a filling machine 1 and an oxygen tank 2. A placement rack 5 is fixedly connected to one side of the filling machine 1. The placement rack 5 is L-shaped, and the oxygen tank 2 is located at the upper end of the placement rack 5. Three sets of inflation pipes 3 are connected to one side of the filling machine 1 and at the upper end of the placement rack 5. An inflation connector 4 is connected to the end of the inflation pipe 3 away from the filling machine 1, and the inflation connector 4 is inserted into the interface of the oxygen tank 2. Three vertical slots 501 are equally spaced on the side of the placement rack 5 away from the filling machine 1. A limit frame 6 is movably connected to the outside of each vertical slot 501, and the oxygen tank 2 is snapped into the inside of the limit frame 6. A baffle 9 is hinged to the upper end of the side of the limit frame 6 away from the placement rack 5.

[0021] As a preferred technical solution in this embodiment, such as Figure 2 As shown, the interior of each of the three vertical slots 501 is rotatably connected to a threaded rod 8 via a throttle. A fixing block 7 is fixedly connected to one side of the limiting frame 6, and the fixing block 7 is slidably connected to the interior of the vertical slot 501 and threadedly connected to the outer surface of the threaded rod 8.

[0022] In this embodiment, the oxygen tank 2 is placed on the upper end of the placement rack 5 and engaged inside the limiting rack 6. Then, according to the height of the oxygen tank 2, the throttle is rotated to drive the threaded rod 8 to rotate, so that the fixing block 7 rotates on the outer surface of the threaded rod 8 and moves up or down along the inside of the vertical groove 501 under the limitation of the vertical groove 501, thereby adjusting the position of the limiting rack 6 according to the height of the oxygen tank 2.

[0023] As a preferred technical solution in this embodiment, such as Figure 3 and Figure 4 As shown, a connecting block 10 is fixedly connected to the bottom end of the baffle 9 away from the hinge end. A movable cavity 1001 is opened inside the connecting block 10. A limiting rod 11 extending through to the outside of the connecting block 10 is movably connected inside the movable cavity 1001. A limiting plate 12 is fixedly connected to the outer surface of the limiting rod 11 on one side inside the movable cavity 1001, and the limiting plate 12 is slidably connected inside the movable cavity 1001. A spring 13 is fixedly connected between one side of the limiting plate 12 and one side of the inner wall of the movable cavity 1001, and the spring 13 is wrapped around the outer surface of the limiting rod 11. A limiting frame 6 is located on the side away from the placement frame 5, and a limiting groove 601 is opened on the outer surface of the limiting frame 6. One end of the limiting rod 11 extending through to the outside of the connecting block 10 is inserted into the limiting groove 601.

[0024] In the embodiment, the baffle 9 is rotated around one side of the upper end of the limiting frame 6, and the limiting rod 11 is pulled, so that the limiting rod 11 drives the limiting plate 12 to compress the spring 13 and moves the other end of the limiting rod 11 to retract into the inside of the movable cavity 1001. When the baffle 9 is rotated away from the end of the rotating shaft to the upper end of the limiting frame 6, the pulling of the limiting rod 11 is released, so that the spring 13 releases the elastic force, and then the limiting rod 11 extends to the outside of the connecting block 10 and is inserted into the limiting groove 601, so as to fix the baffle 9 to the front end of the limiting frame 6, avoiding the oxygen tank 2 from falling.

[0025] When the oxygen filling device is used, the oxygen tank 2 is placed on the upper end of the placing frame 5 and clamped in the inside of the limiting frame 6, and then the rotating handle is rotated to drive the threaded rod 8 to rotate, so that the fixed block 7 is screwed on the outer surface of the threaded rod 8 and moves up or down along the inside of the vertical groove 501 under the limiting of the vertical groove 501, so as to adjust the position of the limiting frame 6 according to the height of the oxygen tank 2. Then the baffle 9 is rotated around one side of the upper end of the limiting frame 6, and the limiting rod 11 is pulled, so that the limiting rod 11 drives the limiting plate 12 to compress the spring 13 and moves the other end of the limiting rod 11 to retract into the inside of the movable cavity 1001. When the baffle 9 is rotated away from the end of the rotating shaft to the upper end of the limiting frame 6, the pulling of the limiting rod 11 is released, so that the spring 13 releases the elastic force, and then the limiting rod 11 extends to the outside of the connecting block 10 and is inserted into the limiting groove 601, so as to fix the baffle 9 to the front end of the limiting frame 6, avoiding the oxygen tank 2 from falling.
