[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-2 In this embodiment, an oxygen tube fixing device is used to fix the oxygen tube to the flow meter head, thereby improving the stability of the oxygen tube after the two are connected.

[0025] Specifically, it includes a regulating valve 1, a connecting pipe 2, a docking joint 3, a pipeline head 4 and a fixing component 5; the connecting pipe 2 is connected to the regulating valve 1, the docking joint 3 is threadedly connected to the end of the docking joint 3 away from the regulating valve 1, and is connected to the regulating valve 1, the pipeline head 4 is sleeved on the outside of the docking joint 3, and a limit ring 6 is sleeved on the outside of the pipeline head 4; at least one raised ring 301 is provided on the outside of the docking joint 3, and corresponding to the raised ring 301, a groove adapted to the at least one raised ring 301 is opened on the inner circumferential wall of the pipeline head 4.

[0026] In actual settings, by setting a raised ring 301 on the outside of the docking joint 3, after the pipe head 4 and the docking joint 3 are docked, the raised ring 301 located on the outside of the docking joint 3 will be embedded in the inside of the groove, thereby increasing the friction between the pipe head 4 and the docking joint 3, and at the same time improving the stability between the pipe head 4 and the docking joint 3.

[0027] See also Figure 3-4 In order to further fix the pipeline head 4, the fixing component 5 in this embodiment is arranged between the connecting pipe 2 and the docking joint 3, and the fixing component 5 includes a U-shaped plate 501, a bottom plate 502 and a clamping plate 503; the U-shaped plate 501 is assembled between the docking joint 3 and the connecting pipe 2, the bottom plate 502 is installed at the bottom of the U-shaped plate 501, and the clamping plate 503 is arranged on the bottom plate 502 and fits with the side of the limiting ring 6 away from the docking joint 3.

[0028] During actual use, the U-shaped plate 501 is installed between the docking joint 3 and the connecting pipe 2. By tightening the docking joint 3, the U-shaped plate 501 is fixed between the docking joint 3 and the connecting pipe 2. After the pipeline head 4 is connected to the docking joint 3, the clamping plate 503 is moved to the front side of the limiting ring 6 and fits with the front side of the limiting ring 6, so as to further improve the stability of the pipeline head 4 after being connected to the docking joint 3.

[0029] Further, in order to adapt to the shape of the outer surface of the pipe head 4, the upper end surface of the clamping plate 503 in the embodiment is concave downward to form an arc-shaped portion, so that the upper end surface of the clamping plate 503 is fitted with the outer peripheral surface of the pipe head 4.

[0030] In addition, in order to install the U-shaped plate 501 between the butt joint 3 and the connecting pipe 2 without disassembling the pipe head 4, the inside of the preferred U-shaped plate 501 in the embodiment is provided with a U-shaped groove downward, and after installation, the bottom plate 502 is located directly below the butt joint 3 and the pipe head 4, and the pipe head 4 is supported by the clamping plate 503, thereby ensuring effective connection of the butt joint 3 and the pipe head 4.

[0031] It should be noted that only the pipe butt joint 3 needs to be loosened during disassembly or installation, so that a gap is reserved between the butt joint 3 and the connecting pipe 2 for the insertion of the U-shaped plate 501.

[0032] Preferably, in order to ensure that the clamping plate 503 is effectively fitted with the limiting ring 6, the fixing assembly 5 in the embodiment further includes a baffle plate 504 arranged on the upper surface of the bottom plate 502 and opposite the U-shaped plate 501, at least one guide rod 505 is assembled between the side opposite the U-shaped plate 501 of the baffle plate 504, and at least one spring 506 is assembled between the clamping plate 503 and the baffle plate 504.

[0033] In actual use, when the clamping plate 503 moves forward, the spring 506 is compressed, so that the spring 506 has a certain elastic potential energy, that is, when the clamping plate 503 moves to the front side of the limiting ring 6, the clamping plate 503 is loosened, at this time the spring 506 automatically rebounds without constraint, thereby pushing the clamping plate 503 to move towards the limiting ring 6, so that the clamping plate 503 is effectively fitted with the front side of the limiting ring 6, and the pipe head 4 has a force moving towards the butt joint 3, so that the pipe head 4 is effectively connected with the butt joint 3.

[0034] In detail, in order to enable the clamping plate 503 to move outside the guide rod 505 and effectively compress the spring 506, a through hole adapted to the guide rod 505 is formed in the inside of the clamping plate 503 in the embodiment, so that the clamping plate 503 can move left and right along the extension direction of the guide rod 505, and the spring 506 is sleeved outside the guide rod 505.

[0035] In addition, in order to improve the stability of the clamping plate 503 during movement, the number of guide rods 505 in the embodiment is preferably two, and the two guide rods 505 are arranged in parallel.

[0036] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
