Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example

[0031] like Figures 1-6 As shown in the figure, an embodiment of this utility model discloses a novel oxygen valve for oxygen cylinders, comprising a valve body 1, an inlet pipe 2 fixedly connected to the lower end face of the valve body 1, an outlet pipe 3 fixedly connected to one side wall of the valve body 1, a protective structure 4 provided on the outlet pipe 3, a valve stem 5 provided inside the valve body 1, an mounting sleeve 6 fixedly connected to the top end of the valve stem 5, a lifting sleeve 7 slidably connected inside the mounting sleeve 6, a set of locking blocks 8 evenly fixedly connected to the outer peripheral side wall of the lifting sleeve 7, a set of locking grooves 9 matching the locking blocks 8 provided inside the mounting sleeve 6, a spring 10 fixedly connected to the inner bottom wall of the mounting sleeve 6, the top end of the spring 10 fixedly connected to the inner top wall of the lifting sleeve 7, and the lifting sleeve... A knob 11 is fixedly connected to the upper end of valve 7. The installation method of valve body 1 and valve stem 5 is existing technology and will not be described in detail here. When the knob 11 is pressed and pushed down, the lifting sleeve 7 will compress the spring 10 and move downward. At this time, the locking block 8 is inserted into the locking groove 9. Rotating the knob 11 will drive the lifting sleeve 7 and the locking block 8 to rotate, thereby causing the mounting sleeve 6 and valve stem 5 to rotate. When the knob 11 is released, the elastic force of the spring 10 will cause the lifting sleeve 7 to return to the initial position, and the locking block 8 will also separate from the locking groove 9. At this time, rotating the knob 11 will not cause the valve stem 5 to rotate, which has good anti-misoperation performance and improves the safety of the oxygen valve.

[0032] like Figure 1 , Figure 3 andFigure 4 As shown, in some embodiments, the protective structure 4 includes two mounting blocks 401 symmetrically arranged on the vent pipe 3. The two mounting blocks 401 are connected by a bolt assembly. A connecting block 402 is fixedly connected to the side wall of each of the two mounting blocks 401. A connecting frame 403 is rotatably connected to the connecting block 402. A protective cover 404 is fixedly connected to the end of the connecting frame 403. The two mounting blocks 401 symmetrically arranged on the vent pipe 3 are connected by a bolt assembly, which facilitates installation and disassembly and also increases the stability of the structure. The design of the connecting block 402 and the connecting frame 403 allows the protective cover 404 to rotate flexibly, which can protect the vent pipe 3 without affecting its normal use. The introduction of the protective cover 404 increases the safety of use, prevents accidental contact and damage to the vent pipe 3, and can also prevent external impurities from entering the interior of the vent pipe 3 during transportation.

[0033] like Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments, the upper surface of the protective cover 404 is fixedly connected with connecting ears 405, one connecting ear 405 is fixedly connected with a magnetic block 406, and the other connecting ear 405 is fixedly connected with an iron piece 407; the cooperation between the magnetic block 406 and the iron piece 407 enables the protective cover 404 to be closed securely, preventing accidental opening, improving the safety of use, and also making it easy for users to quickly and conveniently open or close the protective cover 404.

[0034] like Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments, a groove 408 is provided on the outer side wall of the protective cover 404, and a rubber pad 409 is fixedly connected to the inner side wall of each of the two mounting blocks 401; the introduction of the rubber pad 409 increases the sealing between the mounting block 401 and the air outlet pipe 3, and improves the stability of the mounting block 401 during installation. The groove 408 makes it convenient for users to open and close the protective cover 404.

[0035] like Figure 3 , Figure 5 and Figure 6 As shown, in some embodiments, there are four locking blocks 8 and four locking slots 9. A set of anti-slip grooves are evenly provided on the outer peripheral sidewall of the knob 11 to ensure that the locking block 8 is inserted into the locking slot 9 so that the rotation of the lifting sleeve 7 can stably drive the mounting sleeve 6 to rotate. The anti-slip grooves increase the user's feel during operation, prevent the knob 11 from slipping, and improve the convenience and safety of use.

[0036] like Figure 3As shown, in some embodiments, both the mounting sleeve 6 and the lifting sleeve 7 have an internal hollow structure design, and the diameter of the lifting sleeve 7 is the same as the inner diameter of the mounting sleeve 6. The hollow structure design reduces the overall weight and facilitates the arrangement of the internal structure. The fact that the diameter of the lifting sleeve 7 is the same as the inner diameter of the mounting sleeve 6 ensures that the lifting sleeve 7 slides smoothly and is accurately positioned within the mounting sleeve 6.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
