DETAILED DESCRIPTION
[0019] The utility model will be further described in combination with the embodiment shown in the drawings.
[0020] A medical oxygen flow meter joint conversion cover, such as Figures 1-4As shown, the device includes a conversion cover body 1, a button 2, a locking plate 201, a reset plate 202, a first elastic element 203, a locking rod 204, a sliding rod 3, a cover plate 302, and a second elastic element 4. The conversion cover body 1 is internally connected to the sliding rod 3. The upper outer side of the conversion cover body 1 has an external thread, allowing for quick connection to a medical oxygen flow meter. The lower inner side of the conversion cover body 1 has an internal thread, allowing for external connection to a humidifier. The lower end of the sliding rod 3 is connected to the cover plate 302. The conversion cover body 1 has an air outlet 103, which the cover plate 302 abuts against. The cover plate 302 seals the air outlet 103, preventing oxygen leakage. The cover plate 302 is connected to the conversion cover body 1 via the second elastic element 4. The top front side of the cover plate 302 has a locking plate 201. A slot is provided on the cover 201, which is adapted to the locking rod 204. A reset plate 202 is provided on the rear side of the top of the cover 302. The reset plate 202 has a reset groove. Buttons 2 are slidably connected to both ends of the convertible cover body 1. The ends of the two buttons 2 that are close to each other are connected to the locking rod 204. When the front button 2 is pressed into the convertible cover body 1, the locking rod 204 will be locked into the slot. The convertible cover body 1 has symmetrical slots 101 arranged inside, and each slot 101 is connected to a first elastic element 203. The other ends of the two first elastic elements 203 are respectively connected to the locking rods 204 on the front and rear sides. The convertible cover body 1, sliding rod 3, locking plate 201 and reset plate 202 are all made of PP material. The use of PP material not only ensures the safety and durability of this convertible cover, but also reduces the potential risks to the patient's health, meeting the high standards of medical equipment.
[0021] like Figures 1-4 As shown, it also includes a sealing ring 102, an O-ring 301, and a sealing element 5. The upper outer side of the conversion cover body 1 is fitted with a sealing ring 102. The sealing ring 102 can prevent oxygen leakage at the connection between the conversion cover and the medical oxygen flow meter 6.
