[0023] The utility model provides an oxygen concentrator that is easy to carry and move through improvement. The technical solution of the utility model is:

[0024] like Figure 1-Figure 5 As shown, an oxygen concentrator that is easy to carry and move includes a mobile base 1 and an oxygen concentrator body 2, the oxygen concentrator body 2 is fixedly connected to the mobile base 1, a universal wheel 3 is arranged at the bottom of the mobile base 1, a handle 4 is fixedly connected to the mobile base 1, a station assembly 5 is arranged at the bottom of the mobile base 1, the station assembly 5 includes a bracket 51 and a rotating plate 52, two brackets 51 are fixedly connected to the bottom of the mobile base 1, two rotating plates 52 are rotatably connected to the two brackets 51 respectively, a driving assembly 6 is arranged on the mobile base 1, the universal wheels 3 are arranged around the bottom of the mobile base 1, and the two rotating plates 52 are located between the four universal wheels 3, the bottom ends of the two rotating plates 52 are in contact with the ground, and are made of wear-resistant rubber material, so when the rotating plates 52 are in contact with the ground, if the mobile base 1 needs to be moved, it is necessary to overcome a large static friction force.

[0025] Furthermore, the station component 5 also includes a slider 53 and a slide bar 54. The two slide bars 54 are slidably connected to the bottom of the mobile seat 1. The two sliders 53 are respectively rotatably connected to the bottom of the two slide bars 54. The two sliders 53 are respectively slidably connected to the two rotating plates 52. The sliders 53 slide in contact with the rotating plates 52. When the slide bar 54 moves up and down, the sliders 53 can move up and down, thereby controlling the rotation of the rotating plates 52 so that the bottom ends of the rotating plates 52 contact or do not contact the ground.

[0026] Furthermore, the station component 5 also includes a sliding seat 55, a sliding groove 56 and a slide 57. The sliding seat 55 is slidably connected to the inside of the mobile seat 1. Two sliding grooves 56 are opened on both sides of the sliding seat 55. The two slides 57 are respectively slidably connected to the inside of the two sliding grooves 56. The two slides 57 are respectively fixedly connected to the two sliding rods 54. The sliding groove 56 is an inclined groove, and the slide 57 can only move up and down with the sliding rod 54. Therefore, the movement of the sliding seat 55 will cause the sliding groove 56 to move, thereby causing the slide 57 to move up and down, and then control the up and down movement of the sliding rod 54.

[0027] Furthermore, the station assembly 5 also includes springs 58. Two springs 58 are fixedly connected between the inner wall of the moving seat 1 and the sliding seat 55. The springs 58 can reset the sliding seat 55 when the pull rope 62 is not subjected to external force.

[0028] Furthermore, the driving assembly 6 includes a pull rope 62 and a pulley 63. The pull rope 62 is fixedly connected to the sliding seat 55, and the pulley 63 is arranged on the inner wall of the moving seat 1. The pull rope 62 moves on the pulley 63 to avoid wear.

Therefore, when the traction rod 64 is lifted, the connecting block 61 can be moved, thereby pulling the pull rope 62 to control the movement of the sliding seat 55.

[0030] The specific working method is as follows: when the oxygen concentrator body 2 needs to be moved, the movable seat 1 only needs to be moved by the handle 4, so that the oxygen concentrator body 2 can be moved accordingly. The movement is achieved by the universal wheel 3. Before moving the movable seat 1 by the handle 4, the traction rod 64 needs to be pulled upward by hand to make the traction rod 64 and the handle 4 fit together, and then the movable seat 1 is moved by the handle 4. When the traction rod 64 moves upward, the connecting block 61 inside the movable seat 1 can be driven to move upward, so that the pull rope 62 is pulled, and the movement of the pull rope 62 drives the sliding seat 55 in the lower movable seat 1 to move, and the movement of the sliding seat 55 causes the slide 57 to move upward, so that the slide rod 57 4 moves upward, the sliding bar 54 moves upward to drive the sliding block 53 to move upward, so that the two rotating plates 52 are lifted upward, and the rotating plate 52 originally in contact with the ground is lifted, so that the movable seat 1 can move through the universal wheel 3, and when there is no need to move the oxygen concentrator body 2, the traction rod 64 is released, and the spring 58 resets the sliding seat 55, and the sliding seat 55 resets to move the carriage 57, the sliding bar 54 and the sliding block 53 downward, so that the rotating plate 52 rotates downward, and the bottom of the rotating plate 52 contacts the ground. Due to the contact surface between the rotating plate 52 and the ground, a large static friction force can be generated between the movable seat 1 and the ground, so that the movable seat 1 is not easy to move, so that the whole device is fixed.
