Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0026] The utility model provides a technical scheme:

[0027] Please refer to Figs. 1-4 A portable oxygen conversion joint, including joint body 1, the bottom of joint body 1 is fixedly connected with conveying pipe 2, the bottom of conveying pipe 2 is fixedly connected with connecting pipe 3, the left and right two ends of connecting pipe 3 are fixedly connected with protective shell 5, the two ends of connecting pipe 3 are fixedly connected with connecting interface 4, the inside of the end of protective shell 5 away from connecting pipe 3 is provided with the through hole of oxygen pipe size adaptation, and the inside of two protective shell 5 is connected with sealing assembly 6.

[0028] The sealing assembly 6 includes telescopic rod 61 fixedly connected to the top and bottom of protective shell 5, sealing block 63 is fixedly connected between the telescopic rod 61, two sealing blocks 63 are fixedly connected with spring 62 on the outer surface of the ring side, and the end of spring 62 away from sealing block 63 is fixedly connected with the inner side wall of protective shell 5.

[0029] The sealing block 63 is a rubber air bag made of rubber, the top of the side close to the protective shell 5 is inclined, the number of the spring 62 is multiple, and the size of the multiple springs 62 is equal and the elastic force is greater than the gravity of the sealing block 63.

[0030] By adopting the above technical scheme, when in use, the connector body 1 is clamped to the oxygen tank interface, the connector body 1 is stably connected with the oxygen tank, then the oxygen pipe to be connected is penetrated through the through hole to the inside of the protective shell 5, the outer surface of the oxygen pipe pushes the sealing block 63 when the oxygen pipe is penetrated, the sealing block 63 drives the telescopic rod 61 and the spring 62 to stretch and retract after being pushed, then when the oxygen pipe is clamped to the outer surface of the connecting interface 4, the rebound of the telescopic rod 61 and the spring 62 drives the sealing block 63 to descend and press the outer surface of the oxygen pipe, at the same time, the sealing block 63 clamps and extrudes the position of the oxygen pipe and the connecting interface 4 close to one end of the connecting interface 4, when the oxygen pipe leaks, the oxygen is transported to the inside of the protective shell 5 from the side of the sealing block 63, as the continuous output of the oxygen, the pressure generated extrudes the sealing block 63, the telescopic rod 61 and the spring 62 are driven to stably seal between the oxygen pipe and the connecting interface 4 after the sealing block 63 is extruded, which is beneficial to improve the sealing performance of the oxygen pipe in use.

[0031] Specifically, as shown in Figs. 2-4 The top and the bottom of the two protective shells 5 away from one end of the connecting pipe 3 are fixedly connected with the fixed pipes 7, the outer surfaces of the two fixed pipes 7 are provided with the pressure valves 8, and the two fixed pipes 7 away from one end of the protective shell 5 are commonly connected with the clamping assembly 9.

[0032] The clamping assembly 9 comprises the connecting ring 91 fixedly connected between the two fixed pipes 7 away from one end of the protective shell 5, the clamping air bag 92 fixedly connected to the side of the connecting ring 91 away from the fixed pipe 7, and the friction balls 93 fixedly connected to the inner side wall of the clamping air bag 92.

[0033] The number of the friction balls 93 is multiple, and the multiple friction balls 93 are equal in size and equidistantly distributed on the inner side wall of the clamping air bag 92.

[0034] By adopting the above technical scheme, when the oxygen inside the protective shell 5 reaches a certain value, the pressure valve 8 opens to deliver the gas inside the protective shell 5 to the inside of the fixed pipe 7, and then the oxygen is delivered to the inside of the connecting ring 91, and then delivered to the cavity 94 through the connecting ring 91. When the gas inside the cavity 94 becomes more, the clamping air bag 92 is stretched out, and the clamping air bag 92 after stretching out wraps the outer surface of the oxygen pipe, and at the same time, the friction ball 93 is attached to the outer surface of the oxygen pipe during the wrapping process of the clamping air bag 92, which increases the contact area between the clamping air bag 92 and the oxygen pipe and improves the stability during the connection process of the oxygen pipe.

[0035] Working principle: when in use, the connector body 1 is clamped to the oxygen tank interface to stably connect with the oxygen tank. The connector body 1 is widely used in the field of medical equipment, especially in the connection conversion of oxygen supply devices. The connector body 1 is often used to realize direct and rapid connection with oxygen pipes and the like. After the stable connection between the connector body 1 and the oxygen tank, the oxygen pipe to be connected is extended to the inside of the protective shell 5, and the outer surface of the oxygen pipe extrudes the sealing block 63. After the sealing block 63 is extruded, it extrudes the telescopic rod 61 and the spring 62. Then the oxygen pipe is clamped to the outer surface of the connecting interface 4. After clamping is completed, the reset of the telescopic rod 61 and the spring 62 drives the sealing block 63 to seal and extrude the connection between the oxygen pipe and the connecting interface 4. Oxygen is delivered to the inside of the connecting pipe 3 through the delivery pipe 2, and then delivered to the oxygen pipe through the connecting interface 4. When oxygen leaks between the oxygen pipe and the connecting interface 4, oxygen enters the inside of the protective shell 5 after passing through the sealing block 63. As the oxygen continues to increase, the gas pressure generated by the oxygen presses the sealing block 63. After the sealing block 63 is pressed, the force generated by the sealing block 63 presses the connection between the oxygen pipe, thereby improving the sealing effect between the oxygen pipe and the connecting interface 4.

[0036] When the oxygen inside the protective shell 5 reaches a certain value, the pressure valve 8 opens, and then the oxygen is delivered to the inside of the connecting ring 91 through the fixed pipe 7. The oxygen is delivered to the cavity 94 through the connecting ring 91. As the oxygen continues to be input, the clamping air bag 92 is stretched out after the oxygen in the clamping cavity 94 increases. The clamping air bag 92 after stretching out wraps the outer surface of the oxygen pipe, and at the same time, the setting of the friction ball 93 improves the friction force of the clamping air bag 92 wrapping the outer surface of the oxygen pipe, thereby improving the stability during the connection process of the oxygen pipe.

[0037] Finally, it should be noted that: the above embodiments are used to illustrate the technical solutions of the present application, but not limited to them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
