DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] The utility model provides a technical solution: Figures 1 to 4 As shown, in this embodiment, a novel oxygen flow brake device includes an oxygen cylinder 1, an airflow regulating member 2 is provided at the upper opening position of the oxygen cylinder 1, an air inlet 3 is provided at the front end of the airflow regulating member 2, and an air valve 4 acting on the oxygen flow is provided at the side end of the airflow regulating member 2 (the air valve 4 is a common prior art, and its internal structure is not described in detail here), and the outer surface of the air valve 4 is provided with a locking mechanism acting on itself, and the locking mechanism is composed of a connecting plate 6, a mounting plate 5, and a locking plate 8. The mounting plate 5 is an annular plate and is sleeved on the outer surface of the air valve 4. The mounting plate 5 is fixedly mounted on the outer wall of the airflow regulating member 2 through the connecting plate 6, and two locking plates 8 are provided on the inner side of the mounting plate 5. The two locking plates 8 are symmetrically distributed on the upper and lower sides of the air valve 4, and the two locking plates 8 are connected to the mounting plate 5 through the adjusting mechanism.

[0021] Among them, the adjustment mechanism is composed of a double-headed screw 9, a rotating part 10, a guide rod 11 and an extension plate 12. The extension plates 12 are fixedly connected to both sides of the locking plate 8. The guide rod 11 slides through the two extension plates 12 located on one side of the air valve 4, and both ends of the guide rod 11 are fixedly connected to the inner wall of the mounting plate 5. The double-headed screw 9 penetrates the two extension plates 12 located on the other side of the air valve 4 and the two ends are respectively connected to the two extension plates 12 by threaded cooperation. The two ends of the double-headed screw 9 are rotatably connected to the inner wall of the mounting plate 5. One end of the double-headed screw 9 penetrates the mounting plate 5 and extends to the outside of the mounting plate 5. The extended end of the double-headed screw 9 is fixedly connected to the rotating part 10.

[0022] When in use, the rotating part 10 is rotated to drive the double-headed screw 9 to rotate. Under the restriction of the double-headed screw 9 and the guide rod 11, the two locking plates 8 cannot rotate. When the double-headed screw 9 rotates, the two locking plates 8 will approach each other or move away from each other. By controlling the two locking plates 8 to approach each other, the air valve 4 can be locked and fixed.

[0023] Among them, the ends of the two locking plates 8 close to each other are fixedly connected with a rubber layer, and a plurality of anti-skid grooves 13 are opened on the outer wall of the air valve 4. The anti-skid grooves 13 are distributed along the axial direction, and the plurality of anti-skid grooves 13 are distributed in a ring array.

[0024] By providing the rubber layer and the anti-skid groove 13 , the friction between the locking plate 8 and the air valve 4 can be increased, so that the air valve 4 is more firmly locked.

[0025] Among them, four fixing bolts 7 are arranged on the connecting plate 6, and the four fixing bolts 7 are located at the four corners of the connecting plate 6. Four threaded holes 14 threadedly matched with the fixing bolts 7 are opened on the outer wall of the airflow adjustment member 2, and the four threaded holes 14 correspond to the four fixing bolts 7 one by one.

[0026] The connecting plate 6 can be fixed to the outer wall of the airflow adjustment member 2 by the threaded cooperation between the fixing bolts 7 and the threaded holes 14 .

[0027] The utility model provides a novel oxygen flow brake device, and the specific working principle is as follows:

[0028] During use, after rotating the air valve 4 to adjust the oxygen flow rate, rotate the rotating part 10 to drive the double-headed screw 9 to rotate. Under the restriction of the double-headed screw 9 and the guide rod 11, the two locking plates 8 cannot rotate. When the double-headed screw 9 rotates, the two locking plates 8 will approach each other or move away from each other. By controlling the two locking plates 8 to approach each other, the air valve 4 can be locked and fixed, thereby preventing the air valve 4 from being accidentally touched by the patient or family members and rotating, which will cause the oxygen flow to change and affect the patient's life safety.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
